Lanthanum modified bentonite (LMB) has been applied to eutrophic lakes to reduce phosphorus (P) concentrations in the water column and mitigate P release from sediments. Previous experiments suggest that natural organic matter (NOM) can interfere with phosphate (PO4)-binding to LMB and exacerbate lanthanum (La)-release from bentonite. This evidence served as motivation for this study to systematically determine the effects of NOM, solution pH, and bentonite as a La carrier on P removal. We conducted both geochemical modeling and controlled-laboratory batch kinetic experiments to understand the pH-dependent impacts of humic and fulvic acids on PO4-binding to LMB and La release from LMB. The role of bentonite was studied by comparing PO4 removal obtained by LMB and La3+ (added as LaCl3 salt to represent the La-containing component of LMB). Our results from both geochemical modeling and batch experiments indicate that the PO4-binding ability of LMB is decreased in the presence of NOM, and the decrease is more pronounced at pH 8.5 than at 6. At the highest evaluated NOM concentration (28 mg C L-1), PO4-removal by La3+ was substantially lower than that by LMB, implying that bentonite clay in LMB shielded La from interactions with NOM, while still allowing PO4 capture by La. Finally, the presence of NOM promoted La-release from LMB, and the amount of La released depended on solution pH and both the type (i.e., fulvic/humic acid ratio) and concentration of NOM. Overall, these results provide an important basis for management of P in lakes and eutrophication control that relies on LMB applications.Wastewater-based epidemiology (WBE) has emerged as a useful tool in the fight to track and contain COVID-19 spread within communities. One of the motives behind COVID-19 WBE efforts is the potential for 'early warning' of either the onset of disease in a new setting or changes in trends in communities where disease is endemic. Many initial reports of the early warning potential of WBE have relied upon retrospective sample analysis, and delays in WBE analysis and reporting should be considered when evaluating the early warning potential of WBE that enable public health action. Our purpose in this manuscript is to establish a framework to critique the potential of WBE to serve as an early warning system, with special attention to the onset of viral shedding and the differential between results reporting for WBE and clinical testing. While many uncertainties remain regarding both COVID-19 clinical presentation and technical factors influencing WBE results, our analysis suggests at most a modest lead time interval ranging from six days for clinical testing to four days for WBE during community-level wastewater surveillance where clinical testing is accessible on-demand with a rapid time to results. This potential lead time for WBE subsequently increases in settings with limited clinical testing capacity or utilization. Care should be taken when reporting 'early detection' of COVID-19 disease trends via WBE to consider underlying causes (e.g., clinical testing lag or delayed result reporting) to avoid misrepresenting WBE potential.

Understanding the temporal trends and change of concentrations of per- and polyfluoroalkyl substances (PFAS) is important to evaluate the health impact of PFAS at both the individual- and population-level, however, limited information is available for pre-diabetic adults in the U.S.

Determine trends and rate of change of plasma PFAS concentrations in overweight or obese U.S. adults and evaluate variation by sex, race/ethnicity, and age.

We described temporal trends of plasma PFAS concentrations using samples collected in 1996-1998, 1999-2001, and 2011-2012 from 957 pre-diabetic adults enrolled in the Diabetes Prevention Program (DPP) trial and Outcomes Study (DPPOS) and compared to serum concentrations from the National Health and Nutrition Examination Survey (NHANES 1999-2000, 2003-2016, adults with BMI≥24kg/m

). We examined associations between participants' characteristics and PFAS concentrations and estimated the rate of change using repeated measures in DPP/DPPOS assuming a first-order elimination female and white participants, likely due to differences in exposure patterns, metabolism or elimination kinetics.

We observed a downward temporal trend in plasma PFOS concentrations that was consistent with the timing for U.S. manufacturers' phaseout. Male and Black participants consistently showed higher PFOS and PFNA than female and white participants, likely due to differences in exposure patterns, metabolism or elimination kinetics.

The World Health Organization (WHO) is currently assessing the potential health effects of exposure to radiofrequency electromagnetic fields (RF-EMFs) in the general and working population. Related to one such health effect, there is a concern that RF-EMFs may affect cognitive performance in humans. The systematic review (SR) aims to identify, summarize and synthesize the evidence base related to this question. Here, we present the protocol for the planned SR.

The main objective is to present a protocol for a SR which will evaluate the associations between short-term exposure to RF-EMFs and cognitive performance in human experimental studies.

We will search the following databases PubMed, Embase, Web of Science, Scopus, and the EMF-Portal. The reference lists of included studies and retrieved review articles will be manually searched.

We will include randomized human experimental studies that assess the effects of RF-EMFs on cognitive performance compared to no exposure or lower exposure. We will inclgistration system, to foster transparency.

The certainty of evidence for each identified outcome will be assessed according to Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Performing the review according to this protocol will allow the identification of possible effects of RF-EMFs on cognitive performance in humans. The protocol has been registered in PROSPERO, an open-source protocol registration system, to foster transparency.Desertification and climate change indicate a future expansion of the global area of dry land and an increase in the risk of drought. Humans may therefore be at an ever-increasing risk of frequent exposure to, and resultant adverse health effects of desert sand dust. This review appraises a total of 52 experimental studies that have sought to identify mechanisms and intermediate endpoints underlying epidemiological evidence of an impact of desert dust on cardiovascular and respiratory health. Toxicological studies, in main using doses that reflect or at least approach real world exposures during a dust event, have demonstrated that virgin sand dust particles and dust storm particles sampled at remote locations away from the source induce inflammatory lung injury and aggravate allergen-induced nasal and pulmonary eosinophilia. Effects are orchestrated by cytokines, chemokines and antigen-specific immunoglobulin potentially via toll-like receptor/myeloid differentiation factor signaling pathways. Findings sugge go some way in clarifying the mechanistic effects of atmospheric desert dust on the upper and lower human respiratory system. In doing so, they provide support for biological plausibility of epidemiological associations between this particulate air pollutant and events including exacerbation of asthma, hospitalization for respiratory infections and seasonal allergic rhinitis.Tissue expansion is widely used to obtain new skin tissue for repairing defects in the clinical practice of plastic surgery. One major complication can be dermal thinning during expansion, which usually leads to skin rupture. Collagen synthesis can determine dermal thickness and can be influenced by macrophage polarization during expansion. The aim of the study was to test whether pigment epithelium-derived factor (PEDF) could be a modulator of collagen synthesis in fibroblasts by regulating macrophage polarization during skin expansion. Our results showed that PEDF mRNA expression was increased in expanded human and mouse epidermis. PEDF protein levels were elevated in the subcutaneous exudates of a rat skin expansion model. Increased PEDF mRNA expression was accompanied by dermal thinning during a three-week expansion protocol. Subcutaneous injection of PEDF in vivo further resulted in dermal thinning and cell number increase of M1 macrophage in the expanded skin. PEDF also promoted macrophage polarization in vitro to the M1 subtype under hypoxic conditions. PEDF did not influence collagen gene expression in fibroblasts directly, but attenuated collagen synthesis in a macrophage-mediated manner. Additionally, blockage of PEDF receptors on macrophages with inhibitors rescued collagen synthesis in fibroblasts. Our research demonstrated PEDF elevation in expanded skin leads to dermal thinning through M1 macrophage-mediated collagen synthesis inhibition in fibroblasts. Our results could form a basis for the development of novel strategies to improve skin integrity in expanded skin by using PEDF.Plant-based polyphenols are natural compounds, present in fruits and vegetables. During recent years, polyphenols have gained special attention due to their nutraceutical and pharmacological activities for the prevention and treatment of human diseases. Nevertheless, their photosensitivity and low bioavailability, rapid metabolism and short biological half-life represent the major limitations for their use, which could be overcome by polyphenols encapsulation (flavonoids and non-flavonoids) into chitosan (CS)-tripolyphosphate (TPP) based nanoparticles (NP). In this review, we particularly focused on the ionic gelation method for the NP design. This contribution exhaustively discusses and compares results of scientific reports published in the last decade referring to ionic gelation applied for the protection, controlled and site-directed delivery of polyphenols. As a consequence, CS-TPP NP would constitute true platforms to transport polyphenols, or a combination of them, to be used for the designing of a new generation of drugs or nutraceuticals.The present study is aimed at valorizing grape pomace, one of the most abundant winery-making by-products of the Mediterranean area, through the extraction of the main bioactive compounds from the skin of grape pomace and using them to manufacture innovative nanoformulations capable of both avoiding skin damages and promoting skincare. The phytochemicals were recovered through maceration in hydroethanolic solution. Catechin, quercetin, fisetin and gallic acid, which are known for their antioxidant power, were detected as the main compounds of the extract. Liposomes and phospholipid vesicles modified with glycerol or Montanov 82® or a combination of both, were used as carriers for the extract. The vesicles were small (~183 nm), slightly polydispersed (PI ≥ 0.28), and highly negatively charged (~-50 mV). The extract was loaded in high amounts in all vesicles (~100%) irrespective of their composition. The antioxidant activity of the extract, measured by using the DPPH (2,2-Diphenyl-1-picrylhydrazyl) test, was 84 ± 1%, and slightly increased when loaded into the vesicles (~89%, P less then 0.05). The grape pomace extract loaded vesicles were highly biocompatible and able to protect fibroblasts (3T3) from the oxidative stress induced by hydrogen peroxide.The treatment of diabetes mellitus aftermaths became one of medicine's most significant therapeutical and financial issues in the XXI century. Most of which are related to protein glycation and oxidative stress caused by long lasting periods of hyperglycemia. Thus, even within a venerable one, searching for new drugs, displaying anti-glycation and anti-oxidative properties seem useful as an additive therapy of diabetes. In this paper, we assessed the anti-glycating properties of phloroglucinol, a drug discovered in the XIX century and still used in many countries for its antispasmodic action. Herewith, we present its effect on protein glycation, glycoxidation, and oxidative damage in an albumin glycation/oxidation model and HepG2 cells treated with high glucose concentrations. The phloroglucinol showed the strongest and the widest protective effect within all analyzed antiglycating (aminoguanidine, pioglitazone) and anti-oxidative (vitamin C, GSH) agents. To the very best of our knowledge, this is the first study showing the properties of phloroglucinol in vitro what once is proven in other models might deepen its clinical applications.Since December 2019, the world was encountered a new disease called coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although SARS-CoV-2 initially causes lung damage, it also affects many other organs, including the kidneys, and on average, 5-23% of people with COVID-19 develop the symptoms of acute kidney injury (AKI), including elevated blood creatinine and urea, hematuria, proteinuria, and histopathological damages. The exact mechanism is unknown, but the researchers believe that SARS-CoV-2 directly and indirectly affects the kidneys. The direct pathway is by binding the virus to ACE2 receptor in the kidney, damage to cells, the renin-angiotensin system disturbances, activating coagulation pathways, and damaging the renal vascular endothelium. The initial evidence from studying the kidney tissue in postmortem patients is more in favor of the direct pathway. The indirect pathway is created by increased cytokines and cytokine storm, sepsis, circulatory disturbances, hypoxemia, as well as using the nephrotoxic drugs. Using renal tissue biopsy and autopsy in the patients with COVID-19, recent studies found evidence for a predominant indirect pathway in AKI induction by SARS-CoV-2. Besides, some studies showed that the degree of acute tubular injury (ATI) in autopsies from COVID-19 victims is milder compared to AKI degree. We review the mechanism of AKI induction and the renal side effects of the most common drugs used to treat COVID-19 after the overview of the latest findings on SARS-CoV-2 pathogenicity.p-Coumaric acid (PC), a naturally occurring phytochemical, possesses antioxidant and anti-inflammatory properties; however, the mechanisms underlying its protective effects against obesity-related metabolic dysfunction are largely unknown. Here, we treated C57BL/6J mice to a high-fat diet (HFD) with or without PC (10 mg/kg body weight/day) for 16 weeks to determine whether PC ameliorates HFD-induced obesity, insulin resistance, inflammation, and non-alcoholic fatty liver disease (NAFLD). We found no significant differences in food intake and body weight between the groups. However, PC-treated mice showed significantly lower white adipose tissue (WAT) weight, adipocyte size, and plasma leptin level, which were associated with decreased lipogenic enzyme activity and mRNA expression of their genes in the epididymal WAT. Moreover, hepatic lipogenic enzymes activities and expression of their genes and proteins were decreased with concomitant increases in hepatic fatty acid oxidation and mRNA expression of its gene; fecal lipid excretion was significantly increased, resulting in decreased liver weight, hepatic lipid levels, lipid droplet accumulation, and plasma aspartate aminotransferase and lipid levels. Additionally, PC-treated mice showed lower fasting blood glucose, plasma resistin, and MCP-1 levels, HOMA-IR, and mRNA expression of inflammatory genes in the epididymal WAT and liver. Our findings reveal potential mechanisms underlying the action of PC against HFD-induced adiposity, NAFLD, and other metabolic disturbances.ACE2 plays a pivotal role in the balance between the pro-oxidative pro-inflammatory and the anti-oxidative anti-inflammatory arms of the renin-angiotensin system. Furthermore, ACE2 is the entry receptor for SARS-CoV-2. Clarification of ACE2-related mechanisms is crucial for the understanding of COVID-19 and other oxidative stress and inflammation-related processes. In rat and monkey brain, we discovered that the intracellular ACE2 and its products Ang 1-7 and alamandine are highly concentrated in the mitochondria and bind to a new mitochondrial Mas-related receptor MrgE (MrgE) to produce nitric oxide. We found MrgE expressed in neurons and glia of rodents and primates in the substantia nigra and different brain regions. In the mitochondria, ACE2 and MrgE expressions decreased and NOX4 increased with aging. This new ACE2/MrgE/NO axis may play a major role in mitochondrial regulation of oxidative stress in neurons, and possibly other cells. Therefore, dysregulation of the mitochondrial ACE2/MrgE/NO axis may play a major role in neurodegenerative processes of dopaminergic neurons, where mitochondrial dysfunction and oxidative stress play a crucial role. Since ACE2 binds SARS-CoV-2 spike protein, the mitochondrial ACE2/MrgE/NO axis may also play a role in SARS-CoV-2 cellular effects.Understanding the neural processes underlying the comprehension of visual images and sentences remains a major open challenge in cognitive neuroscience. We previously demonstrated with fMRI and DTI that comprehension of visual images and sentences describing human activities recruits a common extended parietal-temporal-frontal semantic system. The current research tests the hypothesis that this common semantic system will display similar ERP profiles during processing in these two modalities, providing further support for the common comprehension system. We recorded EEG from naïve subjects as they saw simple narratives made up of a first visual image depicting a human event, followed by a second image that was either a sequentially coherent narrative follow-up, or not, of the first. Incoherent second stimuli depict the same agents but shifted into a different situation. In separate blocks of trials the same protocol was presented using narrative sentence stimuli. Part of the novelty is the comparison of sentence and visual narrative responses. ERPs revealed common neural profiles for narrative processing across image and sentence modalities in the form of early and late central and frontal positivities in response to narrative incoherence. There was an additional posterior positivity only for sentences in a very late window. These results are discussed in the context of ERP signatures of narrative processing and meaning, and a current model of narrative comprehension.

Recent trends show methamphetamine use is increasing in the United States. American Indian and Alaska Native (AI/AN) communities face health disparities compared to the population overall, including some of the highest rates of illegal drug use. Herein, we examined the prevalence of methamphetamine use among AI/ANs and characteristics associated with methamphetamine use among AI/AN people.

We examined past-year methamphetamine use from 2015 to 2019 between AI/ANs and the general non-institutionalized U.S. population using the National Survey of Drug Use and Health. Then, we identify potential subgroups of AI/AN people at elevated risk of methamphetamine use across factors including demographic, social determinants, mental health, and co-occurring substance use.

A total of 214,505 people, aged 18 or older, were surveyed between 2015 and 2019; 3,075 (0.55%) identified as AI/AN. An estimated 26.2 out of every 1000 AI/ANs used methamphetamine compared to 6.8 out of every 1000 in the general U.S.

Compared to methamphetamine use in the general population, AI/AN methamphetamine use tends to cluster in rural areas and among those with low income. AI/ANs who use methamphetamine were more likely to be male, middle-aged, low income, have severe mental illness, and misuse other substances than AI/AN people who did not use methamphetamine.

AI/ANs experience a disproportionate amount of methamphetamine use in the U.S. To address this disparity, multifaceted, broad prevention, harm reduction, and treatment efforts are needed that leverage cultural strengths to mitigate the consequences of methamphetamine use.

European estimates of adolescent smoking cessation are lacking and studies on the role of schools in quit behaviour are scarce. We aimed to describe smoking cessation attempts and success among adolescents in Europe and explored the association with school policy and programmes.

We used cross-sectional data from the 2013 and 2016-2017 surveys of the European SILNE and SILNE-R projects. We included 4,509 12-19-year-old current or ex-smokers in 67 secondary schools in seven countries (Belgium, Germany, Finland, Ireland, Italy, the Netherlands, and Portugal). School staff reported strength of smoke-free school policies (SFSPs), proportion of grades in which anti-tobacco education was offered, and whether the school offered any form of cessation support programme. Multilevel logistic regression analysis determined school-level variation and the association of school-level and individual-level variables with self-reported and self-defined quit attempts and quit success.

Over three quarters (77.3%) of students reported a quit attempt and half of them (50.1%) reported quit success. Prevalence rates of quit success and quit attempts, showed relatively small variations between schools within countries. Associations of smoke-free school policy, tobacco educational programmes and cessation programmes with quit attempts and quit success could not be demonstrated with statistical significance. Quit attempts and quit success were inversely associated with alcohol use, parental smoking, and friend smoking.

This study demonstrates that adolescence is an important time to encourage quitting and to support quit attempts. We did not find evidence for a contribution of school policies and programmes to quit behaviour of adolescent smokers.

Betrayal trauma, as defined by (Freyd, 1996), refers to a subcategory of trauma characterized by a significant violation of trust surrounding interpersonal maltreatment (physical, sexual, or emotional). Previous research has shown that people with betrayal trauma histories experience greater dissociative symptoms of posttraumatic stress disorder and co-morbid substance use disorder symptoms. Women in the criminal legal system commonly have significant histories of betrayal trauma and related posttraumatic stress symptoms and substance use. However, no studies have specifically explored the impact of dissociative posttraumatic stress symptoms on substance use outcomes in this population. Additionally, no studies have explored whether betrayal trauma relates to nonfatal overdoses.

This cross-sectional survey study of N = 508 women with criminal legal system involvement examined the indirect effects of betrayal trauma history on substance use outcomes through dissociative posttraumatic stress symptoms.

Multivariate analyses supported an indirect effect of betrayal trauma on substance use severity, daily substance use, and history of overdose, but not alcohol use severity, through dissociative symptoms.

Women in the criminal legal system with betrayal trauma and dissociative symptoms may be at risk for substance use and related outcomes (i.e., overdose). Future work is needed to examine whether targeting such symptoms may improve substance use treatment and prevention of serious outcomes in this population.

Racially diverse sexual minority men (SMM) are disproportionately impacted by the U.S. HIV epidemic. Substance use, particularly stimulant use, may impact viral suppression for SMM living with HIV. The current study sought to characterize patterns of substance use via latent class analysis (LCA) and test associations between those patterns and future viral load outcomes, among SMM living with HIV.

Data were drawn from Thrive With Me (TWM), an RCT of an mHealth intervention targeting ART adherence among SMM living with HIV. LCA was performed with six dichotomous indicators of substance use, derived from validated measures and urinalysis results, to determine substance use classes at baseline. Bivariate and multivariable logistic regression models tested associations between baseline substance use classes and HIV viral load 5-months post-baseline.

Among 383 SMM living with HIV, we identified a three-class model of substance use fit best low probability substance use (81.3 %), high probability hazardous alcohol, marijuana, and cocaine use (7.5 %), and high probability methamphetamine and amphetamine use (11.2 %). Additionally, the high probability amphetamine use class was less likely to be virally suppressed at 5-month follow-up compared to the low probability substance use class [Adjusted Odds Ratio = 3.34, 95 % Confidence Interval = 1.39-7.99, p = .0069].

We identified that some patterns of substance use (i.e., methamphetamine and amphetamine use), but possibly not others (e.g., alcohol, marijuana, and cocaine use), are potentially important intervention targets for improving HIV-related outcomes among racially diverse SMM living with HIV.

One of the theoretical explanations of SSM errors is similarity bias - the tendency to search for similar targets and to miss the dissimilar ones. The current study focuses on both perceptual and categorical similarity and their individual roles in SSM. Five experiments investigated the role of perceptual and categorical similarity in subsequent search misses, wherein perceptual and categorical similarities were manipulated separately, and task relevance was controlled. The role of both perceptual and categorical similarity was revealed, however, the categorical similarity had greater impact on second target detection. The findings of this research suggest the revision of the traditional perceptual set hypothesis that mainly focuses on perceptual target similarity in multiple target visual search.While second generation tyrosine kinase inhibitors (2GTKIs) are highly effective therapies for chronic myeloid leukemia (CML), a significant minority of patients who initiate a 2GTKI will require a switch to an alternative TKI. The long-term outcomes of those who require a change in therapy after front-line 2GTKI therapy are largely undescribed. Here we describe the clinical outcomes associated with switch to an alternative TKI after first-line therapy with a 2GTKI. Of 232 patients who initiated a 2GTKI during the study period, 76 (33 %) switched to an alternative TKI. Reasons for switching included intolerance (79 %) and resistance (21 %). Among the 60 patients who switched due to intolerance, 53 (88 %) were able to achieve or maintain a major molecular response (MMR) with 5-year progression-free survival (PFS) 90.5 % (95 % CI 90.4-90.6 %). Amongst the 16 patients who switched due to resistance, 8 patients (50 %) were able to achieve MMR with 5-year PFS 80.4 % (95 % CI 80.2-80.6 %). Most patients who switched due to intolerance remained on their second-line TKI. Approximately 25 % of patients who initiate first-line 2GTKI in a real world setting will ultimately switch to an alternate TKI due to intolerance. Patients who switch for intolerance continue to enjoy excellent clinical outcomes.

Data on composite and sequential lymphoma between primary mediastinal lymphoma/diffuse large B-cell lymphoma (LBCL) and classical Hodgkin lymphoma (cHL) are rare.

We identified 25 cases with composite lymphoma (CL), 116 cases developing LBCL as a second primary cancer after cHL (cHL-LBCL), and 74 cases developing cHL as a second primary cancer after LBCL (LBCL-cHL) from the Surveillance, Epidemiology, and End Results (SEER) 18 database. Comparisons of overall survival (OS) and lymphoma cause-specific survival (CSS) between patients with cHL-LBCL or cHL-LBCL and their de novo counterparts were performed.

The 5-year OS of patients with CL was 74.8 %. No significant difference in unadjusted OS and lymphoma CSS were observed between patients with de novo LBCL (LBCL-1 group) and patients with cHL-LBCL. However, the age- and stage-adjusted cHL-LBCL group had inferior OS and lymphoma CSS compared with that in the LBCL-1 group. The unadjusted and adjusted OS and lymphoma CSS in the LBCL-cHL group were significantly worse than patients with de novo cHL.

CL between LBCL and cHL may have good outcomes. cHL survivors had poorer outcomes after a LBCL diagnosis versus patients with LBCL-1. Significantly poor outcomes were observed in patients with LBCL-cHL compared with patients with de novo cHL.

The translocation t(1519) produces the oncogenic BRD4-NUT fusion which is pathognomonic for NUT carcinoma (NC), which is a rare, but extremely aggressive solid tumor. Comprehensive genomic profiling (CGP) by hybrid-capture based next generation sequencing of 186+ genes of a cohort of advanced cancer cases with a variety of initial diagnoses harboring BRD4-NUT may shed further insight into the biology of these tumors and possible options for targeted treatment.

Thirty-one solid tumor cases harboring a BRD4-NUT translocation are described, with only 16% initially diagnosed as NC and the remainder carrying other diagnoses, most commonly NSCLCNOS (22%) and lung squamous cell carcinoma (NSCLC-SCC) (16%). The cohort was all microsatellite stable and harbored a low Tumor Mutational Burden (TMB, mean 1.7 mut/mb, range 0-4). In two index cases, patients treated with immune checkpoint inhibitors (ICPI) had unexpected partial or better responses of varying duration. Notably, four cases - including the two index caseredicted high affinity of the BRD4-NUT fusion peptide to MHC complexes. Further study of pMHC affinity and response to immune checkpoint inhibitors in patients with NC harboring BRD4-NUT is needed to validate this therapeutic hypothesis.The aim of the study was to determine effects of four commercial marinades on the colour, tenderness, cooking loss and sensory characteristics of semimembranosus beef muscles before and after sous-vide (SV) treatment. Muscles (n = 24) were marinated using Odessa (O; red pepper, garlic, onion), Mexico (M; red pepper, tomato), Old Polish (OP; pepper, garlic), and Bordeaux (B; pepper, red pepper, garlic) marinades for 24 h at 4 °C. Marinades uptake ranged from 3.3% (M) to 4.4% (B). Marinating and SV significantly affected all colour parameters. In SV beef, the highest values of L* were noted in OP and O samples, whereas the highest a* and b* values in M samples. Overall, marinating reduced (P less then 0.05) cooking loss (34.6%) and shear force (19.5%). The use of marinating prior to SV treatment beneficially affected taste, tenderness and juiciness of beef. OP marinade allowed to obtain beef steaks with the best sensory quality and the lowest shear force.Carcass attributes of steers were examined for influences of selection for residual feed intake (RFI), and exposure to different levels of prenatal nutrition. Heifers characterized for RFI corrected for backfat were mated to bulls with genetic potential for either High-RFI or Low-RFI, such that the progeny were expected to be H/H or L/L RFI (sire/dam). Pregnant heifers were assigned to a low diet (Ldiet; 0.40 kg/d ADG), or moderate diet (Mdiet; 0.57 kg/d ADG), from 30 to 150 days of gestation, after which all heifers were managed similarly. Steer offspring (n = 23) were also managed similarly until slaughter. Dressing percentage of steers from H-RFI dams/sires exposed to Ldiet during gestation was lower than all other groups (P = 0.02). Marbling was greater for steers from H-RFI parents, as was fat content of longissimus thoracis et lumborum and triceps brachii (P ≤ 0.02). Results suggest that parental selection for RFI and prenatal maternal diet can influence carcass characteristics of progeny.

Neuropsychiatric symptoms and CSF cytokine, chemokine, and SARS-COV-2 antibody profiles are unknown in pediatric patients with COVID-19 or multisystem inflammatory syndrome (MIS-C), (NP-COVID-19).

Children at a single pediatric institution quaternary referral center with laboratory-confirmed COVID-19 or MIS-C and neuropsychiatric symptoms were included in this retrospective case series. Clinical symptoms, ancillary testing data, treatments and outcomes are described. Multiplexed electrochemiluminescence assays for cytokines, chemokines and SARS-CoV-2 antibodies were tested in the CSF NP-COVID-19 patients compared to five controls and were analyzed using the Student's t-test.

Three of five NP-COVID-19 patients had psychiatric symptoms, and two patients had encephalopathy and seizures. All patients had full or near resolution of neuropsychiatric symptoms by discharge. One patient received intravenous steroids for treatment for psychiatric symptoms; 3/5 other patients received immunotherapy for MIS-C, inclammatory chemokines and SARS-CoV-2 antibodies may serve as biomarkers of SARS-CoV-2 mediated NP-COVID-19. Additional study is required to understand the pathophysiologic mechanisms of neuroinflammation in children with COVID-19 and MIS-C.

Multiple sclerosis-related optic neuritis is mostly associated with good recovery. The aim of this study was to investigate the causes of progressive visual worsening in multiple sclerosis patients despite treatment.

We retrospectively reviewed the medical records of multiple sclerosis patients with optic neuritis admitted to the ward of our Neurology Department between 2001 and 2020. The patients with unilateral/bilateral progressive visual loss or non-substantial recovery of visual acuity were screened for genetic testing for Leber's hereditary optic neuropathy.

Of 1014 multiple sclerosis patients, 411 (39%) reported having optic neuritis. During follow-up, 11 patients manifested atypical characteristics of multiple sclerosis-related optic neuritis (presence of one of the following clinical findings bilateral simultaneous or sequential eye involvement, progressive visual loss, or no response to corticosteroids during hospitalization), while others presented with typical multiple sclerosis-related optiwithout recovery during follow-up. Because Leber's hereditary optic neuropathy mitochondrial mutations indicate relatively poor visual prognosis and have important implications for genetic counseling.Delineation and quantification of normal and abnormal brain tissues on Magnetic Resonance Images is fundamental to the diagnosis and longitudinal assessment of neurological diseases. Here we sought to develop a convolutional neural network for automated multiclass tissue segmentation of brain MRIs that was robust at typical clinical resolutions and in the presence of a variety of lesions. We trained a 3D U-Net for full brain multiclass tissue segmentation from a prior atlas-based segmentation method on an internal dataset that consisted of 558 clinical T1-weighted brain MRIs (453/52/53; training/validation/test) of patients with one of 50 different diagnostic entities (n = 362) or with a normal brain MRI (n = 196). We then used transfer learning to refine our model on an external dataset that consisted of 7 patients with hand-labeled tissue types. We evaluated the tissue-wise and intra-lesion performance with different loss functions and spatial prior information in the validation set and applied the best performing model to the internal and external test sets. The network achieved an average overall Dice score of 0.87 and volume similarity of 0.97 in the internal test set. Further, the network achieved a median intra-lesion tissue segmentation accuracy of 0.85 inside lesions within white matter and 0.61 inside lesions within gray matter. After transfer learning, the network achieved an average overall Dice score of 0.77 and volume similarity of 0.96 in the external dataset compared to human raters. The network had equivalent or better performance than the original atlas-based method on which it was trained across all metrics and produced segmentations in a hundredth of the time. We anticipate that this pipeline will be a useful tool for clinical decision support and quantitative analysis of clinical brain MRIs in the presence of lesions.In this study, the biochar (BC) supported Fe-Cu bimetallic stabilized by PVP (Fe-Cu/PVP/BC) were prepared and utilized to enhance the nitrate (NO3-) removal and the selectivity toward nitrogen (N2). Results showed the optimum FeCuBC ratio and the dosage of the BC (pyrolysis at 700 °C) supported Fe-Cu bimetallic stabilized by polyvinylpyrrolidone (PVP) (Fe-Cu/PVP/BC700) were respectively 123 and 1 mg L-1 with the selectivity toward N2 of 31 %. This was mainly due to the synergy among Fe0, Cu0 and BC in the Fe-Cu/PVP/BC. The addition of Fe0 could reduce the NO3- through providing electron. The Cu0 and BC improved the selectivity of NO3- to N2 through forming [Cu-NO2-ads] and adjusting redox potential. The addition of Fe-Cu/PVP/BC could supply electrons for denitrification and enhance the relative abundances of Azospira and Thauera related to denitrification to improve NO3- removal. This result was further confirmed by the variations of denitrifying functional genes (narG, nirK, nirS and nosZ). This research provided an effective method to improve NO3- removal during surface water treatment in constructed wetlands (CWs) by adding Fe-Cu/PVP/BC.In several countries, flower import regulations are restricted to food security, by establishing maximum residue limits (MRL) for pesticides in flower-based food products and biosafety, in order to limit the circulation of vectors, pests and exotic species across borders. In this context, the lack of limits on pesticides in flower-products for ornamental purposes can influence the pesticide overuse in production areas, as well as the transfer of contaminated products between countries. Therefore, the purpose of this review was to discuss possible adverse effects on human and environmental health of pesticides used in floriculture, evaluating regulations on the use of these pesticides in the main importing and flower-producing countries. This review included 92 documents. The use of 201 compounds was identified by interviews and analytical measurements. Among them, 93 are banned by the European Union (EU), although 46.3 % of these compounds have been identified in samples from European countries. Latin American countries have a large number of scientific publications on pesticides in flower production (n = 51), while the EU and China have less studies (n = 24) and the United States and Japan have no studies. Regarding adverse health effects, poorer neurobehavioral development, reproductive disorders, congenital malformations and genotoxicity have been reported for residents of flower production areas and workers throughout the flower production cycle. Studies including water samples show overuse of pesticides, while environmental impacts are related to water and air contamination, soil degradation and adverse effects on the reproduction and development of non-target organisms. This review points out that the absence of MRL for non-edible flowers can be crucial for the trade of contaminated products across borders, including pesticides banned in importing countries. Furthermore, setting limits on flowers could reduce the use of pesticides in producing countries.Expanding applications of metal-oxide nanoparticles (NPs) and increased environmental deposition of NPs followed by their interactions with edible crops threaten yields. This study demonstrates the effects of aging (45 days in soil) of four NPs (ZnO, CuO, Al2O3, TiO2; 3.9-34 nm) and their corresponding metal oxide bulk particles (BPs; 144-586 nm) on cucumbers (Cucumis sativus L.) cultivated in sandy-clay-loam field soil and compares these with the phytotoxic effects of readily soluble metal salts (Zn2+, Cu2+, and Al3+). Data revealed the cell-to-cell translocations of NPs, their attachments to outer and inner cell surfaces, nuclear membranes, and vacuoles, and their upward movements to aerial parts. Metal bioaccumulations in cucumbers were found in the order (i) ZnO-NPs > ZnO-BPs > Zn2+, (ii) CuO-NPs > CuO-BPs > Cu2+, (iii) Al3+> Al2O3-NPs > Al2O3-BPs and (iv) TiO2-NPs > TiO2-BPs. Aging of NPs in soil for 45 days significantly enhanced metal uptake (P ≤ 0.05), for instance aged ZnO-NPs at 1 g kg-1 increased the uptake by 20.7 % over non-aged ZnO-NPs. Metal uptakes inhibited root (RDW) and shoot (SDW) dry weight accumulations. For Cu species, maximum negative impact (%) was exhibited by Cu2+ (RDWSDW = 9465) followed by CuO-NPs (RDWSDW = 7834) and CuO-BPs (RDWSDW = 2722). Aging of NPs/BPs at 1-4 g kg-1 further enhanced the toxic impact of tested materials on biomass accumulations and chlorophyll formation. NPs also induced membrane damage of root tissues and enhanced levels of antioxidant enzymes. The results of this study suggest that care is required when aged metal-oxide NPs of both essential (Zn and Cu) and non-essential (Al and Ti) metals interact with cucumber plants, especially, when they are used for agricultural purposes.With the exploitation of lead-zinc deposits, lead content around mining areas has seriously exceeded the recommended level. The most challenging problem is how to reduce lead contamination in soil efficiently. In this study, we developed a method to remediate lead-contaminated soil by adding Morchella mycelium. First, we compared the repair effects of mycelium and hyperaccumulator by conducting pot experiments. Then, we investigated the mechanism through which mycelium repairs lead-contaminated soil by conducting simulation experiments. Results showed that using mycelium was a more efficient way to repair soil than using hyperaccumulator. Compared with the untreated group, mycelium reduced the lead content of crops by 34.83 % and raised dry biomass by 134.05 % when lead addition was 800 mg/kg. After mycelium fixation, soil catalase, urease, cellulase, and sucrase activities were significantly enhanced, and the bioavailability of lead decreased significantly. The lead solution exposure simulation test showed that Morchella mycelium immobilized lead due to its extracellular secretions. That is, mycelium secreted metabolites and lead to form salt crystals, reducing bioavailable lead content. In addition, Morchella mycelium restoration may effectively improve soil fertility and increase crop yields. Thus, mycelium may be used successfully in alternative green repair methods for environmental heavy metal remediation.Knowledge about how the COVID-19 pandemic can affect aquatic wildlife is still extremely limited, and no effect of SARS-CoV-2 or its structural constituents on invertebrate models has been reported so far. Thus, we investigated the presence of the 2019-new coronavirus in different urban wastewater samples and, later, evaluated the behavioral and biochemical effects of the exposure of Culex quinquefasciatus larvae to two SARS-CoV-2 spike protein peptides (PSPD-2002 and PSPD-2003) synthesized in our laboratory. Initially, our results show the contamination of wastewater by the new coronavirus, via RT-qPCR on the viral N1 gene. On the other hand, our study shows that short-term exposure (48 h) to a low concentration (40 μg/L) of the synthesized peptides induced changes in the locomotor and the olfactory-driven behavior of the C. quinquefascitus larvae, which were associated with increased production of ROS and AChE activity (cholinesterase effect). To our knowledge, this is the first study that reports the indirect effects of the COVID-19 pandemic on the larval phase of a freshwater invertebrate species. The results raise concerns at the ecological level where the observed biological effects may lead to drastic consequences.Our research on the operation of legal institutions related to the restriction of the legal capacity of adults (custodianship and supported decision-making) started in December 2019. Our present analysis of case law on custodianship and supported decision-making is based on cases published in the Collection of Court Decisions. The adoption of the new Hungarian Civil Code has clearly had a significant effect on the court decisions, as it made it compulsory to designate the categories of decisions to which a partial restriction on legal capacity applies. However, the change in regulation also implies a change of attitude that is considerably less apparent in the cases. In the context of international human rights expectations, any limitation of legal capacity should be applied as circumspectly as possible, and only in the most necessary cases. In the examined cases, the efforts of the Curia (the Hungarian Supreme Court) to reinforce this change of attitude in court practice may be detected but they are not exteal and judicial proceedings.Traditionally, infants have learned how to interact with objects in their environment through direct observations of adults and peers. In recent decades these models have been available over different media, and this has introduced non-human agents to infants' learning environments. Humanoid robots are increasingly portrayed as social agents in on screen, but the degree to which infants are capable of observational learning from screen-based robots is unknown. The current study thus investigated how well 1- to 3-year-olds (N = 230) could imitate on-screen robots relative to on-screen and live humans. Participants exhibited an imitation deficit for robots that varied with age. Furthermore, the well-known video deficit did not replicate as expected, and was weak and transient relative to past research. Together, the findings documented here suggest that infants are learning from media in ways that differ from past generations, but that this new learning is nuanced when novel technologies are involved.Language shapes object categorization in infants. This starts as a general enhanced attentional effect of language, which narrows to a specific link between labels and categories by twelve months. The current experiments examined this narrowing effect by investigating when infants track a consistent label across varied input. Six-month-old infants (N = 48) were familiarized to category exemplars, each presented with the exact same labeling phrase or the same label in different phrases. Evidence of object categorization at test was only found with the same phrase, suggesting that infants were not tracking the label's consistency, but rather that of the entire input. Nine-month-olds (N = 24) did show evidence of categorization across the varied phrases, suggesting that they were tracking the consistent label across the varied input.Both the movements of people and inanimate objects are intimately bound up with physical causality. Furthermore, in contrast to object movements, causal relationships between limb movements controlled by humans and their body displacements uniquely reflect agency and goal-directed actions in support of social causality. To investigate the development of sensitivity to causal movements, we examined the looking behavior of infants between 9 and 18 months of age when viewing movements of humans and objects. We also investigated whether individual differences in gender and gross motor functions may impact the development of the visual preferences for causal movements. In Experiment 1, infants were presented with walking stimuli showing either normal body translation or a "moonwalk" that reversed the horizontal motion of body translations. In Experiment 2, infants were presented with unperformable actions beyond infants' gross motor functions (i.e., long jump) either with or without ecologically valid body displacement. In Experiment 3, infants were presented with rolling movements of inanimate objects that either complied with or violated physical causality. We found that female infants showed longer looking times to normal walking stimuli than to moonwalk stimuli, but did not differ in their looking time to movements of inanimate objects and unperformable actions. In contrast, male infants did not show sensitivity to causal movement for either category. Additionally, female infants looked longer at social stimuli of human actions than male infants. Under the tested circumstances, our findings indicate that female infants have developed a sensitivity to causal consistency between limb movements and body translations of biological motion, only for actions with previous visual and motor exposures, and demonstrate a preference toward social information.

Intimate partner violence is a global problem with significant adverse sequelae. Healthcare education in this area is limited, and healthcare students and professionals generally lack the confidence to communicate with, and clinically manage patients experiencing intimate partner violence.

This study aimed to examine the perceptions of undergraduate paramedicine students about intimate partner violence and its management, and intimate partner violence education.

A qualitative, exploratory study.

An Australian undergraduate paramedicine program.

Second- and third-year paramedicine students.

Second-year paramedicine students were provided with intimate partner violence information in the form of relevant literature, a lecture and an online educational package, and a group clinical scenario session. Third-year students were not offered this information or experience. Both 2nd and 3rd year students then participated in a one-on-one clinical scenario with a standardised patient. The students intervieweed by intimate partner violence. Students value this education and are supportive of its incorporation in undergraduate paramedicine programs.

The inclusion of a multi-modal intimate partner violence education package, including the utilisation of a standardised patient can be useful in improving paramedicine student confidence to interact with and manage patients impacted by intimate partner violence. Students value this education and are supportive of its incorporation in undergraduate paramedicine programs.
