Airborne microplastic pollution detected in the atmosphere of the South Shetland Islands in Antarctica.

Plastic pollution has emerged as a growing environmental concern, affecting even the most remote regions of the planet as the Antarctic continent, endangering its ecosystem and contributing to climate change. In this context, a continuous atmospheric microplastics monitoring study was conducted at Carlini Argentine Antarctic Station located in the southwest of 25 de Mayo (King George) Island (South Shetlands). Passive samplers were installed at three locations throughout the station, chosen based on the intensity of human activity and proved to be effective in collecting atmospheric particles over a one-year study period.

Severe Antiphospholipid Syndrome and Diffuse Glomerulonephritis After Adalimumab Treatment in a Patient With Ulcerative Colitis.

Tumor necrosis factor alpha inhibitors (TNFi) are biological drugs used worldwide to treat various autoimmune disorders. Paradoxically, TNF- antagonists can also induce autoimmune diseases being systemic vasculitis, systemic lupus erythematosus, and psoriasis, the most common. We present a 22-year-old woman with ulcerative colitis (UC) who was started on adalimumab 40 mg subcutaneously every 2 weeks.

Reversion of metabolic dysfunction-associated steatohepatitis by skeletal muscle-directed FGF21 gene therapy.

The highly prevalent metabolic dysfunction-associated steatohepatitis (MASH) is associated with liver steatosis, inflammation, and hepatocyte injury, which can lead to fibrosis and may progress to hepatocellular carcinoma and death. New treatment modalities such as gene therapy may be transformative for MASH patients. Here, we describe that one-time intramuscular administration of adeno-associated viral vectors of serotype 1 (AAV1) encoding native fibroblast growth factor 21 (FGF21), a key metabolic regulator, resulted in sustained increased circulating levels of the factor, which mediated long-term (>1 year) MASH and hepatic fibrosis reversion and halted development of liver tumors in obese male and female mouse models.
