007 by Adonis analysis). Specifically, according to the results of linear discriminate analysis effect size, probiotics raised the proportions of family Bacteroidaceae and Enterococcaceae, and reduced Ruminococcaceae, Halomonadaceae, Peptostreptococcaceae, Clostridiales Family XIII. https://www.selleckchem.com/products/Elesclomol.html Incertae Sedis and Erysipelotrichaceae in non-diabetic HD patients. Additionally, probiotics reduced the abundances of several uremic retention solutes in serum or feces, including indole-3-acetic acid-O-glucuronide, 3-guanidinopropionic acid, and 1-methylinosine (P  less then  0.05). In the probiotic arm, no significant changes were observed in other secondary outcomes. CONCLUSIONS Taken together, outcomes from this study suggest that probiotics do have benefits on improving intestinal imbalances and lowering exposure to several uremic toxins in HD patients.Pine trees are used as biomonitoring agents to evaluate atmospheric polycyclic aromatic hydrocarbons (PAHs). Due to industrialization, urban construction, and rapid population growth, the city of Bursa is experiencing air pollution. In this study, PAHs were measured in pine tree branches and needles at a wastewater treatment plant site, an industrial site, and semirural site in Bursa for 12 months. The concentrations fluctuated depending on the characteristics of the areas. The lowest concentration value was measured in the semirural site while the highest value was determined in the wastewater treatment plant site. The PAH concentrations in pine needles ranged from 24 to 2565 ng/g dry weight (DW) and in pine branches from 163 to 2871 ng/g DW for 16 PAHs. Naphthalene, phenanthrene, fluorene, and fluoranthene were determined as dominant species in both tree components. Diagnostic ratios, ring profile, principal component analysis, the coefficient of divergence, and the Pearson correlation coefficient methods were used in the definition of sources of PAHs in the sampling sites, although all source identification methods have advantages and disadvantages. According to the results, the PAHs mainly originated from biomass and coal burning, traffic, and mixed sources. It also was concluded that three sampling sites showed higher PAH concentrations during winter, and the main PAH sources were similar.Recent studies have shown that inflammatory diseases are becoming more frequent throughout the world. The causes of these disorders are multifactorial and include genetic, immunological, and environmental factors, and intestinal microbiota dysbiosis. The use of beneficial microorganisms has shown to be useful in the prevention and treatment of disorders such as colitis, mucositis, and even colon cancer by their immune-stimulating properties. It has also been shown that certain vitamins, especially riboflavin and folate derivatives, have proven to be helpful in the treatment of these diseases. The application of vitamin-producing lactic acid bacteria, especially strains that produce folate and riboflavin together with immune-stimulating strains, could be used as adjunct treatments in patients suffering from a wide range of inflammatory diseases since they could improve treatment efficiency and prevent undesirable side effects in addition to their nutrition values. In this review, the most up to date information on the current knowledge and uses of vitamin-producing lactic acid bacteria is discussed in order to stimulate further studies in this field.Betulinic acid (BA), a lupane-type triterpenoid, mainly distributes in birch plants. It has been reported that BA and its derivatives possess potent anticancer and anti-HIV activities. Commercial production of BA to date depends on phytochemical extraction and semi-synthesis from betulin (a biosynthetic precursor of BA). The biosynthetic pathway of BA has been completely revealed so far. The relevant enzymes involved in BA biosynthesis are summarized in this review. The studies on construction of biotechnological platforms for production of BA and other related triterpenoids are subsequently reviewed. The engineering strategies include overexpression of rate-limiting enzymes of triterpenoid biosynthesis, balancing flux between triterpenoid biosynthetic pathway and others, engineering endoplasmic reticulum, and improving cofactor availability. At the end, this review also attempted to provide future perspectives on potential strategies for further optimizing biosynthesis of BA and other triterpenoids in microbial hosts. KEY POINTS • Summarizes the relevant enzymes involved in betulinic acid (BA) biosynthesis. • Highlights recent advances in biotechnological production of BA-related compounds. • Provides future perspectives on strategies for optimizing triterpenoid biosynthesis.Anthropogenic warming's effects on phenology across environmental and temporal gradients are well recognized. Long-term phenological monitoring data are often limited in duration and geographic scope, but recent efforts to digitize herbaria collections make it possible to reliably reconstruct historic flowering phenology across broad geographic scales and multiple species, lending to an increased understanding of community response to climate change. In this study, we examined collection dates (1901 to 2015) of 8540 flowering specimens from 39 native species in the Pacific Northwest (PNW) region of North America. We hypothesized that flowering phenology would be sensitive to temperature but that sensitivity would vary depending on blooming season and geographic range position. As expected, we found that early-season bloomers are more sensitive to temperature than later-season bloomers. Sensitivity to temperature was significantly greater at low elevations and in the maritime (western) portion of the PNW than at higher elevations and in the eastern interior, respectively. The elevational and longitudinal effects on flowering sensitivity reflect spring "arriving" earlier at low elevations and in the maritime portion of the PNW. These results demonstrate that phenological responses to warming vary substantially across climatically diverse regions, warranting careful and nuanced consideration of climate warming's effects on plant phenology.
