Background And Aims: Alcohol-related liver disease (ALD) is one of the leading causes of severe liver disease with limited pharmacological treatments for alcohol-related steatohepatitis (ASH). CD44, a glycoprotein mainly expressed in immune cells, has been implicated in multiple inflammatory diseases but has never been studied in the ALD context. We therefore studied its contribution to ASH development in mice and its expression in ALD patients.

Radiotherapy can be limited by pneumonitis which is impacted by innate immunity, including pathways regulated by TRAIL death receptor DR5. We investigated whether DR5 agonists could rescue mice from toxic effects of radiation and found two different agonists, parenteral PEGylated trimeric-TRAIL (TLY012) and oral TRAIL-Inducing Compound (TIC10/ONC201) could reduce pneumonitis, alveolar-wall thickness, and oxygen desaturation. Lung protection extended to late effects of radiation including less fibrosis at 22-weeks in TLY012-rescued survivors versus un-rescued surviving irradiated-mice.

Eccentric contraction- (ECC) induced force loss is a hallmark of murine dystrophin-deficient (mdx) skeletal muscle that is used to assess efficacy of potential therapies for Duchenne muscular dystrophy. While virtually all key proteins involved in muscle contraction have been implicated in ECC force loss, a unifying mechanism that orchestrates force loss across such diverse molecular targets has not been identified. We showed that correcting defective hydrogen sulfide (H2S) signaling in mdx muscle prevented ECC force loss.

Purpose Of Review: This review explores the mechanistic pathways and clinical implications of phytochemicals in obesity management, addressing the global health crisis of obesity and the pressing need for effective, natural strategies to combat this epidemic.
Recent Findings: Phytochemicals demonstrate significant potential in obesity control through various molecular mechanisms. These include the modulation of adipogenesis, regulation of lipid metabolism, enhancement of energy expenditure, and suppression of appetite.
Virulent and multidrug-resistant Aeromonas in aquatic environments of Kerala, India: potential risks to fish and humans.

Aeromonas inhabit diverse aquatic habitats and are recognized as both opportunistic and primary pathogens of fish and humans. This study delineates the biochemical and gyrB sequence-based molecular identification of 14 Aeromonas strains isolated from aquatic environments in Kerala, India, identifying them as A. dhakensis (50%), A.
