Cholestasis is characterized by hepatic accumulation of cytotoxic bile acids (BAs), which often subsequently leads to liver injury, inflammation, fibrosis, and liver cirrhosis. Fibroblast growth factor 21 (FGF21) is a liver-secreted hormone with pleiotropic effects on the homeostasis of glucose, lipid, and energy metabolism. However, whether hepatic FGF21 plays a role in cholestatic liver injury remains elusive.

Article Synopsis
  • - Spinocerebellar ataxias (SCAs) are a group of genetic neurodegenerative diseases, primarily affecting coordination and movement, and are often caused by certain repeat expansions in DNA that lead to polyglutamine (polyQ) proteins.
  • - These diseases primarily impact the cerebellum, which is crucial for controlling eye movements, resulting in various oculomotor impairments that are characteristic of different SCA types.
  • - The review discusses the eye movement abnormalities and genetic, clinical, and neuropathological aspects of common polyQ-SCAs, highlighting that analyzing these eye movements can aid in accurately diagnosing these disorders.

  • - PLU1 is often found at higher levels in various cancers, including breast and colorectal cancer, but its role in glioma progression was previously unclear, prompting this investigation into its relationship with glioma development.
  • - The study utilized various methods, including clinical database analysis and laboratory experiments, to show that higher PLU1 expression correlates with more advanced stages of glioma and that inhibiting PLU1 decreases cell proliferation and migration.
  • - Results indicate that PLU1 not only relates to glioma progression but also plays a critical role in glucose metabolism within glioma cells, suggesting it could be a potential target for new treatment strategies.

  • - This study examines how serum calcium levels relate to coagulopathy and the risk of hemorrhagic progression in patients with traumatic intraparenchymal hemorrhage (tIPH) by analyzing data from patients admitted to a hospital between 2016 and 2019.
  • - Among the 473 patients analyzed, those with lower serum calcium levels were more likely to experience coagulopathy and hemorrhagic progression, with hypocalcemia identified as a significant risk factor.
  • - The findings suggest that while hypocalcemia may increase the risk of hemorrhagic progression, there is no direct interaction between low calcium levels and coagulopathy; instead, coagulopathy mediates a portion of the relationship between calcium levels and hemorrh

Agricultural drainage ditches can prevent flooding and mitigate agricultural pollution; however, the performance is unsatisfactory in plateau areas like the Dianchi Lake basin. Thus, a novel double-layer ditch system (DDS) with a fibrous packing as biofilm carriers was developed to form the carrier-attached biofilms and enhance the pollutant removal. The results indicated the DDS performed better than a single-layer ditch system, and annual average removal efficiencies of TN, NO-N, NH-N, TP, COD and SS were 18.
