Summary: This study found that the use of probiotics in salmonid aquaculture can enhance disease resistance. The researchers developed a new, low-cost application method for rapidly revitalizing probiotic bacteria. The continuous application stabilizes the gut microbiota without excessive immune stimulation, while the cyclic application provides an opportunity for immune system activation in periods of stress.

Summary: The study investigated the acute response and long-term effects of repeated exposure to non-medical dextromethorphan (DXM) use during adolescence on adult behavior. The locomotor stimulant effect of DXM was stronger in adolescents compared to adults, and only adolescent rats showed locomotor sensitization after 10 days of DXM administration. Cross-sensitization to ketamine was evident in adolescent-treated rats. DXM also led to an increase in perseverative errors in reversal learning specifically in the adolescent-treated group. These findings suggest that repeated DXM use during adolescence may contribute to addiction and cognitive deficits.

Summary: After decades of research, cancer remains a major challenge in medical research, and colorectal cancer is one of the most common types. Although colonoscopy is a life-saving examination for preventing CRC, its unpleasant side effects and impact on gut microbiome have hindered its acceptance. However, a 30-day intervention with a multi-species probiotic formulation was found to significantly reduce the adverse events caused by bowel preparation and improve patient comfort.

Summary: The study demonstrated that flavan 3-ol (FLs) may induce browning of adipose tissue in mice by activating the sympathetic nervous system (SNS), leading to increased expression of uncoupling protein (Ucp)-1 and thermogenic transcriptome factors. This effect was confirmed by a marked increase in urinary catecholamine (CA) levels, suggesting enhanced SNS activity.

Summary: This study identified the role of TGFB signaling in intestinal regeneration following injury. TGFB1 was found to induce fetal-like transcriptional signature and enhance the regenerative response in the epithelium. Additionally, TGFB1 treatment enhanced the ability of primary epithelial cultures to engraft into damaged murine colon, suggesting potential for cellular therapy.

Summary: This article provides a detailed review of how physiological and anatomical differences between the small and large intestine affect the composition, function, and plasticity of the gut microbiota, highlighting the importance of understanding these differences for manipulation of the gut microbiota.

Summary: This study analyzed the biochemical, histological, and gene expression alterations induced by chronic administration of diethylnitrosamine (DEN) and 2-acetylaminofluorene (2-AAF) in wistar rats. The treated group showed significant increases in total cholesterol, HDL-C, AST, ALT, ALKP, and GGT levels, as well as histological changes in the liver and lung. Gene expression analysis revealed significant differences in genes related to fibrosis, inflammation, apoptosis, cell growth, angiogenesis, lipid metabolism, and alpha-fetoprotein (AFP). These findings highlight the heterogeneity of hepatocellular carcinoma and demonstrate the characteristic alterations induced by DEN+2-AAF in Wistar rats.

Summary: The study found that MTX induced astroglial and microglial reactions, leading to responses in multiple areas of the central nervous system. In the MTX5 group, this appeared to occur in the presence of decreased proinflammatory cytokines.

Summary: The gut microbiota plays a crucial role in health and disease. Probiotics have shown potential as microbiota-targeted therapies to improve host health, but the underlying molecular mechanisms are not well understood. This study investigated the effects of a probiotic formula on the small intestinal microbiota and identified significant changes in pathobionts, nutrient utilization, and metabolites. The findings highlight the potential of network theory in identifying and improving microbiota-targeted therapies.

Summary: This study investigated the effects of azithromycin (AZM) administered alone or with probiotic bacteria (Lactobacillus rhamnosus; LR) on bones in estrogen-deficient rats. The results showed that LR or AZM may have positive effects on certain skeletal parameters of estrogen-deficient rats.

Summary: Gender plays a critical role in defining drug-induced plasticity in the nucleus accumbens, with cocaine administration capable of rewriting basal proteomic function and reward-associated behaviors. The differential effects on protein expression between males and females eliminate sex differences observed under basal conditions.

Summary: Research has found that DON can induce apoptosis in intestinal epithelial cells through the FOXO3a-signaling pathway, leading to the translocation of FOXO3a into the nucleus. Inhibiting FOXO3a can alleviate apoptosis and the expression of apoptosis-related genes. Additionally, treatment with an ERK1/2 inhibitor can suppress the translocation of FOXO3a into the nucleus.

Summary: Research reveals that exposure to hypoxia in ancestors can lead to reduced lipids and fertility in the descendants reared in normoxia. The transmission of these phenotypic consequences is dependent on histone-modifying enzymes and argonaute HRDE-1. Additionally, small RNAs can be transmitted from parents to their naïve children, resulting in fertility defects.
