3-1960 ng/dm2 and fluorotelomer alcohols (FTOHs) at 9.7-7188 ng/dm2. High concentrations of FTOHs were also observed in one oil-proof paper bag at 454-2595 ng/dm2 and in one French fries paper bag at 22.4-167 ng/dm2.Leishmaniasis remains a serious public health problem in many tropical regions of the world. Among neglected tropical diseases, the mortality rate of leishmaniasis is second only to malaria. All currently approved therapeutics have toxic side effects and face rapidly increasing resistance. To identify existing drugs with antileishmanial activity and predict the mechanism of action, we designed a drug-discovery pipeline utilizing both in-silico and in-vitro methods. First, we screened compounds from the Selleckchem Bio-Active Compound Library containing ~1622 FDA-approved drugs and narrowed these down to 96 candidates based on data mining for possible anti-parasitic properties. Next, we completed preliminary in-vitro testing of compounds against Leishmania amastigotes and selected the most promising active compounds, Lansoprazole and Posaconazole. We identified possible Leishmania drug targets of Lansoprazole and Posaconazole using several available servers. Our in-silico screen identified likely Lansoprazole targets as the closely related calcium-transporting ATPases (LdBPK_352080.1, LdBPK_040010.1, and LdBPK_170660.1), and the Posaconazole target as lanosterol 14-alpha-demethylase (LdBPK_111100.1). Further validation showed LdBPK_352080.1 to be the most plausible target based on induced-fit docking followed by long (100ns) MD simulations to confirm the stability of the docked complexes. We present a likely ion channel-based mechanism of action of Lansoprazole against Leishmania calcium-transporting ATPases, which are essential for parasite metabolism and infectivity. The LdBPK_111100.1 interaction with Posaconazole is very similar to the known fungal orthologue. Herein, we present two novel anti-leishmanial agents, Posaconazole and Lansoprazole, already approved by the FDA for different indications and propose plausible mechanisms of action for their antileishmanial activity.A three-step stacking capillary electrophoresis (CE) composed of field-amplified sample injection, sweeping, and analyte focusing by micellar collapse (FASI-sweeping-AFMC) was developed to determine dabigatran (D) and its major active metabolite, dabigatran acyl-beta-d-glucuronide (DAG), in human plasma. After optimization and validation, this novel approach was further applied to monitor 5 real samples, and the 25.2-186.8 ng mL-1 D could be observed among those. Based on these results, the novel CE stacking strategy was successfully applied for the analysis of D and DAG in human plasma and could be served as a tool for clinical assays.

Cryptosporidium is a protozoan parasite causing diarrhoea in humans and animals. Although Cryptosporidium has been found in domestic horses (farmed or kept at pasture), there has been only one published study of Cryptosporidium infections in Chinese racehorses, which was restricted to a very small geographical area.

To investigate the presence of Cryptosporidium spp. in the faeces of racehorses in China and to perform molecular characterisation of the parasite.

Cross-sectional.

A total of 621 fresh faecal samples were collected for DNA extraction from racehorses at 17 equestrian clubs from 12 provinces of China from December 2016 to May 2018. All the DNA were analysed for the presence of Cryptosporidium species/genotypes and subtypes by PCR amplification of the small subunit ribosomal RNA and 60 kDa glycoprotein genes respectively.

PCR analysis revealed that 11 samples (1.8%) were positive for Cryptosporidium spp. Among them seven samples were identified as C. parvum and four were C. hominis. The C. parvum isolates were identified as subtype IIdA14G1 (n=4) and IIdA15G1 (n=3), while all C. hominis isolates were identified as subtype IkA18G1 (n=4).

A single faecal sample from each horse was used instead of multiple samples that could improve the detection rates of the parasite.

Although Cryptosporidium infection rate was relatively low in the investigated racehorses, the presence of zoonotic subtypes IIdA14G and 1IIdA15G1 of C. buy GI254023X parvum and IkA18G1 of C. hominis, suggesting that these animals are a potential source of Cryptosporidium in humans.

The small GTPases RAN play fundamental roles in numerous cellular processes. Although RAN GTPases have been characterized in plants, their roles in cellular processes are far from understood. We report here that RAN GTPases in Arabidopsis are critical for gametophytic development. RAN1 loss-of-function showed no defects in gametophytic development likely due to redundancy. However, the expression of a dominant negative or constitutively active RAN1 resulted in gametophytic lethality. Genetic interference of RAN GTPases caused the arrest of pollen mitosis I and of mitosis of functional megaspores, implying a key role of properly regulated RAN activity in mitosis during gametophytic development.

The aim of this study was to perform an updated description of adolescent occupational exposures reported to the US poison centers.

We performed a descriptive analysis of adolescents aged 13 to 19 years with unintentional occupational exposures from 2011 to 2020 using the National Poison Data System. A clinically significant occupational poisoning (CSOP) case is defined as exposures with moderate effect, major effect, or death. Differences in substance categories between younger (13 to 17 years) and older (18 to 19 years) adolescents with CSOP were compared.

There were 14,374 adolescent occupational exposures. There were 2151 CSOPs. The most common substance categories associated with CSOP were household cleaners (22.3%), chemicals (20.8%), industrial cleaners (14.2%), fumes/gases/vapors (10.8%), and hydrocarbons (5.9%). Categories of exposures were similar across age groups.

This study found that, despite a reduction in the number of adolescent occupational exposures, CSOPs persist.

Mental distress of employees from the financial, public transport, public service, and industrial sector was examined in a cross-sectional study during the second COVID-19 (coronavirus disease 2019) wave in Germany and retrospectively at its beginning.

Mental distress in terms of anxiety and depression symptoms was assessed with the Patient Health Questionnaire-4. High and potential occupational SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection risk (OSIR) was defined based on job information from 1545 non-health care workers.

The risks for more severe mental distress symptoms increased threefold and twofold, respectively, among employees with high and potential OSIR compared with employees without OSIR. Mental distress severity differed by the extent of work-privacy conflicts, perceived job protection, interactions with colleagues, and overcommitment.

Reducing COVID-19 exposure through workplace protective measures, strengthening interactions among colleagues, and supporting employees with work-privacy conflicts could help better protect employees' mental health.

Flagellar dyneins drive sperm motility, which accounts for the consumption of high amounts of ATP. The two main ATP-producing metabolic pathways are compartmentalized in sperm oxidative phosphorylation in the midpiece and glycolysis in the principal piece. The relative preponderance of these pathways has been discussed for decades (the so-called sperm energy debate). The debate has been muddled by species-specific variances and by technical constraints. But recent findings suggest that sperm from most mammalian species employ a versatile metabolic strategy to maintain motility according to the physiological environment. Different metabolic pathways likely coordinate by using exogenous and/or endogenous substrates in order to produce ATP efficiently. Defects in any of these pathways (glycolysis, mitochondrial oxidative phosphorylation, Krebs cycle, fatty acids oxidation, and ketone bodies oxidation, among others) may disturb sperm motility and be at the origin of male infertility. Understanding sperm bioenergetics is thus crucial for building new diagnostic tools, and for the development of treatments for patients presenting with low sperm motility. Some of these patients may benefit from personalized metabolic supplementations and dietary interventions.

The functional integration of these topics would open new avenues for treating diseases synergistically. However, these two individual topics have only been occasionally merged, probably because of the lack of functionalized design of macrocyclic host and the lack of efficient recognition between host and guest drugs. Herein, a "drug-in-drug" strategy is proposed, in which an active drug is encapsulated by a macrocycle possessing therapeutic activity to form a multifunctional supramolecular active pharmaceutical ingredient. As a proof-of-concept, a complex of hydroxychloroquine (HCQ) with sulfonated azocalix[4]arene (HCQ@SAC4A) is prepared to treat rheumatoid arthritis (RA) in a combined fashion. SAC4A is a therapeutic agent that exhibits scavenging capacity for reactive oxygen species and exerts an anti-inflammatory effect. It is also a hypoxia-responsive carrier that can deliver HCQ directly to the inflammatory articular cavity. Consequently, HCQ@SAC4A achieves the synergistic anti-inflammatory effect on both inflamed RAW 264.7 cells and RA rats. This effect is attributed to the temporal and spatial consistency of the two active ingredients of the complex. As a new paradigm for combinational therapy, the drug-in-drug strategy advances in easy preparation, mix-and-match combination, and precise ratiometric control.

To examine the association and potential mediators between rotating night shift work and serum lipid profiles in Chinese steelworkers.

Different exposure metrics of night shifts collected through face-to-face personal interviews. Serum lipid profiles were measured using an automatic biochemical analyzer. Generalized linear models and mediation analyses were used to analyze the main associations.

Compared with day workers, the total cholesterol level in night-shift workers increased in those with 13 to 20 years of night shifts and in those with average frequency of four or more night shifts per month. The association between the duration of night shifts and the total cholesterol level was mediated by systolic and diastolic blood pressure and body mass index.

Rotating night-shift work for 13 to 20 years was associated with an increase in the total cholesterol levels in steelworkers, and blood pressure and body mass index may be involved in the causal pathway.
