3-HKA Promotes Vascular Remodeling After Stroke by Modulating the Activation of A1/A2 Reactive Astrocytes.
Adv Sci (Weinh)

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing, 100070, China.
Ischemic stroke is the most common cerebrovascular disease and the leading cause of permanent disability worldwide. Recent studies have shown that stroke development and prognosis are closely related to abnormal tryptophan metabolism. Here, significant downregulation of 3-hydroxy-kynurenamine (3-HKA) in stroke patients and animal models is identified.

Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

Liver ischemia-reperfusion (IR) injury is a common complication following liver surgery, significantly impacting the prognosis of liver transplantation and other liver surgeries. Betaine-homocysteine methyltransferase (BHMT), a crucial enzyme in the methionine cycle, has been previously confirmed the pivotal role in hepatocellular carcinoma, and it has also been demonstrated that BHMT inhibits inflammation, apoptosis, but its role in liver IR injury remains unknow. Following I/R injury, we found that BHMT expression was significantly upregulated in human liver transplant specimens, mice and hepatocytes.

Flagella are essential for motility and pathogenicity in many bacteria. The main component of the flagellar filament, flagellin (FliC), often undergoes post-translational modifications, with glycosylation being a common occurrence. In PAO1, the b-type flagellin is -glycosylated with a structure that includes a deoxyhexose, a phospho-group, and a previous unknown moiety.

Department of Ophthalmology, Affiliated Hospital of North Sichuan Medical College, Nanchong, Sichuan, China.
Purpose: Ocular neovascularization is a major cause of blindness. Although fibroblast growth factor-2 (FGF2) has been implicated in the pathophysiology of angiogenesis, the underlying mechanisms remain incompletely understood. The purpose of this study was to investigate the role of FGF2 in retinal neovascularization and elucidate its underlying mechanisms.
