Social separation, or the absence of social support, can cause physical and psychological health issues. Social separation is crucial for the welfare of the Yangtze finless porpoise (YFP) in captivity because they face many challenges like frequent social separation, noise from visitors, and animal replacement, which can cause psychological and physiological stress. This research is aimed at assessing the potential negative impacts of social separation on the gut microbiome and metabolome of captive YFP, focusing on the potential imbalances caused by mother-calf separation.

Treatment of inflammatory bowel disease (IBD), a common chronic intestinal disease, by exopolysaccharides (EPSs) produced by lactic acid bacteria has raised increasing concerns. Here, the EPS produced by NMGL2 was evaluated for its ameliorating effect on dextran sodium sulfate (DSS)-induced IBD in mice. Administration of the EPS was shown to decrease the body weight loss and the values of disease activity index (DAI) and alleviate the colon damage as evidenced by an improvement in colonic length shortening, a reduction in colonic coefficient, and a reduction in colonic mucosal architecture and inflammatory infiltration.

Article Synopsis
  • This research explores how variable viscosity, activation energy, and microgravity affect the performance of Darcy nanofluid in improving thermal energy storage (TES) via solar collectors.
  • The study emphasizes that using nanofluid can enhance heat and mass transfer in TES applications, which include heat exchangers and solar power systems, especially when combined with solar radiation and phase change materials.
  • A mathematical model is developed to simulate oscillating heat transfer in TES, revealing that lower viscosity increases fluid velocity while higher activation energy and microgravity lead to better thermal and mass transfer efficiencies.

  • Cancer remains a leading cause of death globally, and while traditional treatments like chemotherapy and surgery exist, they often harm normal cells and face issues like drug resistance, highlighting the need for new therapies.
  • Microbial products, particularly Azurins, show promise as cancer treatments, as they can target cancer cells, like those in breast cancer, without damaging healthy cells.
  • Researchers have created a fusion protein, Azurin-BR2, combining Azurin with a cell-penetrating peptide to enhance its effectiveness; computational analyses suggest it can effectively bind to the p53 protein, potentially triggering cancer cell death and aiding targeted tumor therapy.
