There was no significant difference betweenfragaria vesca, hamamelis and tormentil. All solutions showed a reducing effect on the glucan formation. No significant difference was observed between fragaria vesca and CHX. Considerable alterations of the pellicle’s ultrastructure manifested by an increase in thickness and electron density resulted from rinsing with the three polyphenolic aqueous extracts.

Fragaria vesca, hamamelis and tormentil significantly reduce initial bioadhesion and glucan formation in situ and are therefore recommended as adjuvant antibacterial oral therapeutics.

The occurrence and fate of four synthetic musks and nine UV-filters were investigated in eight full-scale sewage treatment plants (STPs) and their receiving aquatic environments in Bangkok and Pattaya, Thailand. All target compounds were detected in every single sample from STPs and surface water with magnitude from ng/L to μg/L. HHCB-lactone and HMS were found as the predominant musk and UV filter in influent and effluent of STPs, respectively. HHCB-lactone was also found with the highest concentration up to 79501 ng/g (dw) in the sludge. Low removal efficiency range from -37% (HHCB-lactone) to 58% (AHTN) were found for four musks in the STPs. The total emission of Σ4musks and Σ9UV-filters were estimated to be up to 16.7 mg/person/day and 0.28 mg/person/day by the STPs. Three synthetic musks and seven UV-filters were detected in fish from the receiving river. Concentration and emission of musks and UV filters found in this study from Thailand were much higher than those reported in many other countries worldwide. The preliminary ecological risk assessment showed that Musk xylene, 4-MBC and OC may pose high risk to aquatic organisms in the riverine and estuarine environment in Thailand.Nonalcoholic fatty liver disease (NAFLD), which is the most prevalent hepatic disorder worldwide, affecting 25% of the general population, describes a spectrum of progressive liver conditions ranging from relatively benign liver steatosis and advancing to nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. Hallmark features of NASH are fatty hepatocytes and inflammatory cell infiltrates in association with increased activation of hepatic nuclear factor kappa-B (NFκB) that exacerbates liver injury. Because no pharmacological treatments exist for NAFLD, emphasis has been placed on dietary approaches to manage NASH risk. Anti-inflammatory bioactivities of catechin-rich green tea extract (GTE) have been well-studied, especially in preclinical models that have detailed its effects on inflammatory responses downstream of NFκB activation. This review will therefore discuss the experimental evidence that has advanced an understanding of the mechanisms by which GTE, either directly through its catechins or potentially indirectly through microbiota-derived metabolites, limits NFκB activation and NASH-associated liver injury. Specifically, it will describe the hepatic-level benefits of GTE that attenuate intracellular redox distress and pro-inflammatory signaling from extracellular receptors that otherwise activate NFκB. In addition, it will discuss the anti-inflammatory activities of GTE on gut barrier function as well as prebiotic and antimicrobial effects on gut microbial ecology that help to limit the translocation of gut-derived endotoxins (e.g. lipopolysaccharides) to the liver where they otherwise upregulate NFκB activation by Toll-like receptor-4 signaling. This summary is therefore expected to advance research translation of the hepatic- and intestinal-level benefits of GTE and its catechins to help manage NAFLD-associated morbidity.Flavonoids, including anthocyanins, are polyphenolic compounds present in fruits, vegetables and dietary supplements. They can be absorbed from the intestine to the bloodstream or pass into the large intestine. Various bacterial species and enzymes are present along the entire intestine. The aim of the present work was to investigate the intestinal metabolism of selected dietary polyphenol and polyphenol glycosides (quercetin, cyanidin-3-O-glucoside, cyanidin-3-O-galactoside, and delphinidin-3-O-galactoside) by human fecal bacteria. Moreover, the metabolism of metabolites formed from these compounds in human colon carcinoma cells (Caco-2) was also point of the interest. Test compounds were added to fresh human stool in broth or to Caco-2 cells in medium and then incubated for 6 or 20 h at 37°C. After incubation, samples were prepared for LC/MS determination. Main metabolic pathways were deglycosylation, hydrogenation, methylation, hydroxylation, and decomposition. 2,4,5-trihydroxybenzaldehyde, as a metabolite of cyanidin glycosides, was detected after incubation for the first time. Metabolites formed by fecal bacteria were further glucuronidated or methylated by intestinal enzymes. This metabolite profiling of natural compounds has helped to better understand the complex metabolism in the human intestine and this work also has shown the connection of metabolism of natural substances by intestinal bacteria followed by metabolism in intestinal cells.

Alcohol induces inflammation and oxidative stress, causing cell damages. We previously demonstrated that astaxanthin (ASTX), a xanthophyll carotenoid, exerts anti-inflammatory and antioxidant properties in macrophages exposed to inflammatory insults. In this study, we investigated whether ASTX can inhibit alcohol-induced inflammation and oxidative stress in macrophages with the elucidation of mechanisms.

RAW 264.7 macrophages and mouse bone marrow-derived macrophages were treated with 80 mM ethanol in the presence or absence of 25 μM of ASTX for 72 h. Subsequently, the expression of genes related to inflammation and oxidative stress, cellular reactive oxygen species accumulation, cellular NAD

level and sirtuin 1 (SIRT1) activity were measured. In addition, RAW 264.7 macrophages were treated with sirtinol or resveratrol, which are known inhibitors or activators of SIRT1 activity, respectively, to determine the contribution of SIRT1 to the inhibitory effect of ASTX on inflammation and oxidative stress in ages.

Hospitalisations with community-acquired pneumonia (CAP) are often not managed in accordance with antimicrobial guidelines. This study aimed to assess whether guideline-driven antimicrobial prescribing for CAP can be improved using an intervention bundle. Secondary measures assessed were hospital length of stay (LOS), mortality, duration of intravenous antibiotics and total antibiotics, improved uptake of appropriate investigations, and documentation of CURB-65 score.

A retrospective cohort of hospitalised CAP patients from August-September 2018 was compared with a post-intervention prospective cohort from May-June 2019. The intervention bundle included a mobile audience response system, promotion of the antimicrobial app, development of a physical card with local guidelines, and incorporating CURB-65 into the unscheduled admission proforma. Local guidelines are in keeping with British Thoracic Society CAP guidelines.

A total of 69 adult patients (aged >18 years) were included in the study (37 retrospective, 32 prospective). Overall compliance with local CAP guidelines improved from 21.6% to 62.5% (P < 0.001). No difference in initial intravenous antibiotic duration was seen (median 4 days vs. 4 days; P = 0.70) and total antibiotic duration was significantly shorter in the post-intervention group (median 9 days vs. 7 days; P = 0.01). No difference in LOS or mortality was seen between the groups. Documentation of CURB-65 improved from 5.4% to 46.9% (P < 0.001). Uptake of streptococcal urinary antigen testing improved from 18.9% to 40.6% (P = 0.024).

A simple, low-cost quality improvement bundle can significantly increase appropriate antimicrobial prescribing and shorten the total antibiotic duration.

Dissolved 137Cs combines with clay minerals in the soil, and hence, it is not expected to easily infiltrate over time. However, previous studies have indicated that 137Cs derived from the older global fallout migrated deeper than that of the Chernobyl accident, and this cannot be explained by only the dissolved 137Cs vertical migration in the soil. Considering the carbon and nutrient dynamics in the forest floor, the 137Cs transfer process in soil via roots may alter its vertical distribution on a decadal scale. Therefore, in this study, we investigated the 137Cs activity concentrations in both roots and soil matrix, by considering four (0-20 cm) or six (0-30 cm) mineral soil layers taken at every 5 cm at seven study sites dominated by one of the six plant species (three coniferous forests, one deciduous forest, two deciduous forests covered by Sasa, and one bamboo forest) in eastern Japan in 2013. Comparing the results of 137Cs activity concentrations between roots and soil matrix taken at the same soil layer, roots at the surface (0-5 cm) layer often showed lower values than the soil matrix. However, roots deeper than 5 cm had higher activity concentrations than the soil matrix, conversely. The 137Cs inventories ratio of roots to soil matrix are about 1% at the 0-5 and 5-10 cm soil layer, and about 2% at the soil layers deeper than 10 cm. These results suggest that decomposition of root litter little affect the short-term vertical migration of 137Cs in the forest soil. However, it indicates that continuous production and mortality of roots with relatively high 137Cs activity concentrations have an important role for changing the vertical distribution of 137Cs on time scale of decades, particularly at deeper soil layers.Rates of alcohol use disorders are increasing in women, and there is growing evidence that both the cognitive and biological consequences of alcohol dependence are distinct in women as compared to men. Despite this, the neurobehavioral outcomes of chronic alcohol exposure are poorly characterized in women and female animals. In this study, we find that ethanol dependence impaired extinction of reward seeking in a food conditioned place preference task in female mice. At the same time point, ethanol-dependent females exhibited astrocytic dysregulation as indicated by a brain region-specific reduction in glial fibrillary acidic protein (GFAP) expression. Using a chemogenetic strategy, we demonstrate that modulating astrocyte function via chemogenetic activation of Gq-signaling in nucleus accumbens astrocytes transiently rescued extinction in ethanol-dependent females without impacting basal reward seeking. These findings identify astrocyte function as a potential target for the restoration of behavioral flexibility following chronic alcohol exposure in females.
