Human Tyrosinase Displayed on the Surface of Chinese Hamster Ovary Cells for Ligand Fishing of Tyrosinase Inhibitors from Medicinal Plants.

Ligand fishing is a promising strategy for the screening of active ingredients from complex natural products. In this work, human tyrosinase (hTYR) was displayed on the surface of Chinese hamster ovary (CHO) cells for the first time; it was then used as bait to develop a new method for ligand fishing. The localization of hTYR on the CHO cell surface was verified by an enzyme activity test and fluorescence microscopy.

High Concentrations of Tilmicosin Promote the Spread of Multidrug Resistance Gene C in the Pig Gut Microbiome Through Mobile Genetic Elements.

The impact of antibiotic therapy on the spread of antibiotic resistance genes (ARGs) and its relationship to gut microbiota remains unclear. This study investigated changes in ARGs, mobile genetic elements (MGEs), and gut microbial composition following tilmicosin administration in pigs. Thirty pigs were randomly divided into control (CK), low-concentration (0.

Soluble CD72 concurrently impairs T cell functions while enhances inflammatory response in sepsis.

Background: Sepsis is defined as multi-organ dysfunction caused by dysregulated host response to infection. This dysregulated host response includes enhanced inflammatory responses and suppressed adaptive immunity, but the molecular mechanisms behind it have not yet been elucidated. CD72, a type II transmembrane protein that is primarily expressed in B cells, was found to play an immunomodulatory role in the immune system and was associated with mortality in patients with sepsis.

Effects of recombinant human growth hormone in severe neurosurgical patients: A single center, retrospective study.

Purpose: To explore the effects of recombinant human growth hormone (r-hGH) on inflammatory mediators, immune cells and prognosis in severe neurosurgical patients.

Methods: From August 2020 to June 2021, a total of 236 patients who admitted to the neurosurgical intensive care unit (NSICU) were retrospectively analyzed. The patients were divided into GH group (97 cases) and nGH group (139 cases) according to whether they received r-hGH treatment.

Sex Differences in the Association Between Cardiovascular Autonomic Neuropathy and Mortality in Patients With Type 2 Diabetes: The ACCORD Study.

Background: Cardiovascular autonomic neuropathy (CAN) is a severe complication of type 2 diabetes. Significant sex-related differences have been observed in type 2 diabetes consequences such as mortality. However, the effect of sex on the association between CAN and mortality in patients with type 2 diabetes is currently unknown.
