All these bone microstructural alterations found in obese mice were reversed by B. pseudocatenulatum CECT 7765. #link# Administration of the bacterium increased (p less then .05) the Wnt/β-catenin pathway gene expression, which could mediate effects on BMD. Bifidobacterium pseudocatenulatum CECT 7765 supplementation increased (p  less then  .05) serum osteocalcin (OC, bone formation parameter), and decreased serum C-terminal telopeptide (CTX) (p  less then  .01) and parathormone (PTH) (p  less then  .05) (both bone resorption parameters). It also altered the microstructure of the femur. In summary, HFD interfered with the normal bone homeostasis leading to increased bone loss. In obese mice, B. pseudocatenulatum CECT 7765 lowered bone mass loss and enhanced BMD by decreasing bone resorption and increasing bone formation.

Although associations between dysregulated glucose metabolism and human rheumatoid arthritis have been reported, the disturbance and influence of glycolytic metabolism on temporomandibular joint osteoarthritis remains unclear. This study aimed to investigate the expression level and metabolite profile of the critical glycolytic enzyme, lactate dehydrogenase A (LDHA) in synovial fibroblasts (SFs) of TMJOA, assess the effect of glycolytic inhibition on synthesis of hyaluronan synthase 2 (HAS2) and inflammation progression in these cells.

Immunohistochemistry and western blotting were performed to detect the expression of LDHA in the lining and sub-lining layers of synovial tissue and SFs. MTT and EdU assays were used to measure the cell proliferation. The cell apoptosis were demonstrated by TUNEL staining and Annexin V/PI double staining. A potent and specific inhibitor of LDHA, GSK2837808A, was administrated to suppress the activity of LDHA and detect the potential efficacy on HAS2.

LDHA expression was d therapeutic approach for TMJOA.Along the Viña del Mar - Concón coastal strip 11,894 litter items were collected, and grouped into 48 different categories (11 litter typologies). The average litter abundance was 0.25 items/m2, plastic items, and cigarette butts being the most common. Hazardous litter can be found along the entire study area, reaching 28.9% (3438 items of 11,894 total items collected distributed in 14 different categories), and an average of 0.071 items/m2. The application of environmental evaluation indices based on litter data, allows categorizing the study area as a clean-moderate coastal strip with some presence of hazardous litter items, and unsatisfactory environmental conditions. Studied sectors were statistically grouped into three specific types that ranged from sectors in optimal environmental conditions (Group A) to sectors in adverse environmental conditions (Group C). link2 The typology and magnitudes of litter found along the study area suggest a combination of sources that mainly include direct activities on the beach (recreational and smoking-related) as well dumping. In the same way, sanitary waste, ocean/waterway items, and items related to surfing activities were observed. Strategies for litter management and environmental quality improvement need to be developed and enforced.Global increase in the use of pharmaceutically-active compounds (PhACs), and their insufficient removal in wastewater treatment plants, have resulted in their continuous release into the marine environment. We investigated the use of the solitary ascidians Herdmania momus, Microcosmus exasperatus, and Styela plicata as bioindicators of three common PhACs in the Israeli coastal waters Bezafibrate, carbamazepine and diclofenac. Both the Mediterranean and the Red-Sea coasts were found contaminated with PhACs, detected at all 11 sampling sites, with four sites contaminated with all three studied PhACs. Diclofenac was most frequent, present in nine of the 11 sites with concentrations reaching 51.9 ng/g of dry weight sample (dw). Bezafibrate and carbamazepine reached concentrations of 47.8 ng/g dw and 14.3 ng/g dw, respectively. The alarming detection of such high concentrations of PhACs in ascidians along Israel's coasts demonstrates both the extent of PhACs contamination in the region, and the potential of ascidians as bioindicators, and emphasizes the urgent need for additional research into PhAC contamination sources and effects.Exposure to Plant Protection Products, PPPs, (fungicides, herbicides and insecticides) is a significant stressor for bees and other pollinators, and has recently been the focus of intensive debate and research. Specifically, exposure through contaminated pollen and nectar is considered pivotal, as it presents the highest risk of PPP exposure across all bee species. However, the actual risk that multiple PPP residues might pose to non-target species is difficult to assess due to the lack of clear evidence of their actual concentrations. To consolidate the existing knowledge of field-realistic residues detected in pollen and nectar directly collected from plants, we performed a systematic literature review of studies over the past 50 years (1968-2018). link3 We found that pollen was the matrix most frequently evaluated and, of the compounds investigated, the majority were detected in pollen samples. Although the overall most studied category of PPPs were the neonicotinoid insecticides, the compounds with the highest median concentrations of residues in pollen were the broad spectrum carbamate carbofuran (1400 ng/g), the fungicide and nematicide iprodione (524 ng/g), and the organophosphate insecticide dimethoate (500 ng/g). In nectar, the highest median concentration of PPP residues detected were dimethoate (1595 ng/g), chlorothalonil (76 ng/g), and the insecticide phorate (53.5 ng/g). Strong positive correlation was observed between neonicotinoid residues in pollen and nectar of cultivated plant species. The maximum concentrations of several compounds detected in nectar and pollen were estimated to exceed the LD50s for honey bees, bumble bees and four solitary bee species, by several orders of magnitude. However, there is a paucity of information for the biggest part of the world and there is an urgent need to expand the range of compounds evaluated in PPP studies.The metal-free, polymeric semiconductor graphitic carbon nitride (g-CN) family is an emerging class of materials and has striking advantages compared to other semiconductors, i.e. ease of tunability, low cost and synthesis from abundant precursors in a chemical environment. Efforts have been done to improve the properties of g-CN, such as photocatalytic efficiency, designing novel composites, processability and scalability towards discovering novel applications as a remedy for the problems that we are facing today. Despite the fact that the main efforts to improve g-CN come from a catalysis perspective, many fundamental possibilities arise from the special colloidal properties of carbon nitride particles, from synthesis to applications. This review will display how typical colloid chemistry tools can be employed to make 'better g-CNs' and how up to now overseen properties can be levered by integrating a colloid and interface perspective into materials chemistry. Establishing a knowledge on the origins of colloidal behavior of g-CN will be the core of the review.The cosmetic industry is one of the fastest growing industrial sectors that is constantly evolving by absorbing new technologies and incorporating innovative yet sustainable products. Cosmetic products are comprised of diverse formulations such as skin care, color cosmetics, hair care, makeup, body care products. Traditionally, cosmetic emulsions are stabilized using surfactants or polymers. Due to its adverse effects on environment, cytotoxicity effects, numerous health hazards, there is a strong drive to shift towards sustainable and surfactant free emulsions. With increasing consumer demand for a safer and more biodegradable products, formulating "surfactant- free" emulsions by replacing conventional stabilizers with particles has gained popularity. In this review, various important aspects and applications of particle stabilized emulsions in cosmetic formulations will be discussed. Importantly, novel ideas on surface modification of particles and use of Janus particles in cosmetic formulations will be discussed.Urban green space may help slow cognitive decline. We extend the investigation towards subjective memory and green space type using latent class analysis and multilevel models of 45,644 individuals in the Sax Institute's 45 and Up Study. Participants with more tree canopy relative to open grass within 1.6 km, compared to similar quantities of both types, tended to have more favourable odds of subjective memory complaints and self-rated excellent memory at baseline. Higher quantities of open grass relative to tree canopy did not afford similar levels of benefit. Socioeconomic factors explained associations between green space and cumulative incidence of memory-related outcomes.

Although sarcoidosis rarely involves the pancreas, such involvement may mimic pancreatic cancer. We herein report a case of pancreatic sarcoidosis giving rise to a cancer-mimicking retention cyst, concomitant with a neuroendocrine adenoma.

A 47-year-old Caucasian male presented to follow-up for a benign-appearing cyst of the tail of the pancreas, detected incidentally on CT scan done for a urinary stone in 2017. He had been asymptomatic since his last presentation. The lesion was found to have increased in size from 1 cm to 3 cm in greater diameter. Yet, a CT angiography showed no evidence of invasion of surrounding organs, vessels, or lymph nodes. The patient had previous medical history of treated sarcoidosis, hypertension, recurrent nephrolithiasis, and gout. Due to the size increment a neoplastic cystic lesion was considered and distal pancreatectomy was performed. Pathologic examination revealed a retention cyst associated with chronic pancreatitis and the presence of non-caseating granulomas consistent with sarcoidosis. In addition, a neuroendocrine adenoma, and an adjacent focus of pancreatic intraepithelial neoplasia-1 and 2 were noted.

Such presentations may be asymptomatic, as in this case, and a multidisciplinary workup is often required. Care must be taken to rule out pancreatic cancer. A possible relationship between pancreatic sarcoidosis and pancreatic cancer merits further study.

The diagnosis of pancreatic sarcoidosis is difficult, and conclusive diagnosis requires histopathologic assessment.

Plasma-derived AAT, indicated for genetic AAT deficiency, is presently being explored for additional medical indications. Unlike Microbiology inhibitor , some anti-inflammatory activities of AAT involve NF-κB-dependent outcomes, e.g., induction of IL-1R antagonist. AAT activities were compared to dexamethasone (DEX), using various in-vitro cells assays, animal studies, and NF-κB-p65 localization and activity studies. Results demonstrate a cytokine shift towards resolution in AAT-treated cells, as opposed to pan-suppression in DEX-treated cells. AAT enhanced, while DEX suppressed LPS-induced IL-1Ra production and re-epithelialization. When drugs were combined, AAT allowed the immunosuppressive DEX activities, while DEX at medium to high levels antagonized beneficial AAT effects. Interestingly, lower levels of DEX maintained the immunosuppressive effect, while allowing upregulation of IL-1Ra. Therefore, AAT may represent a distinct endogenous anti-inflammatory, resolution-promoting agent that may improve tissue well-being while preventing undesired corticostroids side effects.
