Global Burden of Major Chronic Liver Diseases in 2021.

Background: This study utilised the Global Burden of Disease data (2010-2021) to analyse the rates and trends in point prevalence, annual incidence and years lived with disability (YLDs) for major chronic liver diseases, such as hepatitis B, hepatitis C, metabolic dysfunction-associated liver disease, cirrhosis and other chronic liver diseases.

Methods: Age-standardised rates per 100,000 population for prevalence, annual incidence and YLDs were compared across regions and countries, as well as the socio-demographic index (SDI). Trends were expressed as percentage changes (PC) and estimates were reported with uncertainty intervals (UI).

Exosomal delivery of rapamycin modulates blood-brain barrier penetration and VEGF axis in glioblastoma.

Exosomes (Exos), nanosized membranous vesicles (30-160 nm), have been validated as an effective drug delivery system capable of traversing biological barriers. Mesenchymal stem cells (MSCs), due to their near-limitless self-renewal capabilities, provide a plentiful source of exosomes for clinical applications. In this study, we utilized an exosome-encapsulated rapamycin (Exo-Rapa) delivery strategy, which permits the use of smaller drug dosages to achieve effects typically seen with higher dosages, thus enhancing drug efficacy.

Metabolic dysfunction-associated steatotic liver disease in adults.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the umbrella term that comprises metabolic dysfunction-associated steatotic liver, or isolated hepatic steatosis, through to metabolic dysfunction-associated steatohepatitis, the progressive necroinflammatory disease form that can progress to fibrosis, cirrhosis and hepatocellular carcinoma. MASLD is estimated to affect more than one-third of adults worldwide. MASLD is closely associated with insulin resistance, obesity, gut microbial dysbiosis and genetic risk factors.

DNA-Encoded Library Screen Identifies Novel Series of Respiratory Syncytial Virus Polymerase Inhibitors.

Respiratory syncytial virus (RSV) remains a public health burden due to unmet therapeutic needs. We recently reported the discovery of a non-nucleoside inhibitor of the RSV polymerase and characterized its binding to a novel pocket within the capping domain of the polymerase. Here, we describe our strategy to diversify the chemical matter targeting this site by screening our DNA-encoded chemical libraries, leading to the discovery of a novel and potent series of molecules that inhibits RSV polymerase's biochemical activity, as well as its viral replication in cells.
