Background: As a natural antioxidant, uric acid has neuroprotective effects. The association between uric acid levels and dementia risk was reported by previous studies. However, recently published studies showed that the relationship between uric acid and dementia risk might be heterogeneous in dementia subtypes.

In this study, we sought to define the pathogenic role of HSD17B13 in triggering liver inflammation. Here, we demonstrate that HSD17B13 forms liquid-liquid phase separation (LLPS) around lipid droplets in the livers of MASH patients.

Background: Post-operative AF is a common complication of surgery operations. Inflammation plays a crucial role in the pathogenesis of post-operative AF.
Ovarian cancer is currently the most lethal gynecological cancer. At present, primary debulking surgery combined with platinum-based chemotherapy is the standard treatment strategy for ovarian cancer. Although cisplatin-based chemotherapy has greatly improved the prognosis of patients, the subsequent primary or acquired drug resistance of cancer cells has become an obstacle to a favorable prognosis.

Background: Limited data are available on the responses to vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant in the Chinese population. This study aimed to investigate whether vaccination could alter the disease course of SARS-CoV-2 Omicron variant.
Methods: A retrospective cohort included 142 patients who had no or mild symptoms and were admitted to our department for centralized isolation after being locally infected with SARS-CoV-2 Omicron variant from March 4 to 30, 2022, in Shanghai, China.
The type III secretion system (T3SS) is an important molecular machinery in gram-negative bacteria Shigella flexneri as it provides ways for translocating virulence factors from the bacteria into host cells, eventually leading to severe disease symptoms such as bacillary dysentery. Due to the rising concerns of antibiotics resistance in bactericidal strategy, the anti-virulence strategy that primarily targets the T3SS components becomes an attractive alternative. MxiM, the secretin pilot protein of Shigella flexneri, binds the secretin MxiD and facilitates the formation of the secretin ring in outer membrane in T3SS assembly.

At the same time, the incidence of psychiatric disorders including depression and anxiety has been increasing. Accumulating elderly and stressed people suffer from these brain disorders, which is undoubtedly a huge burden on the modern aging society.

Mitochondria may serve as a potential therapeutic target for PTCL. A designed positively-charged segment (pKV) is anchored to the specific 15 amino acid sequence (MIASHLLAYFFTELN) to yield a cell-penetrating peptide (pHK-pKV) and a lipid chain (Pal) is conjugated to the N-terminus of pHK-pKV (Pal-pHK-pKV) are bioactive amphiphilic peptide assemblies targeting the interaction between mitochondrial voltage dependent anion channel 1 (VDAC1) and hexokinase II (HKII).

Hence, we aimed to clarify the mechanisms and potential targets between TGYP and CHB. The active compounds and related putative targets of TGYP, and disease targets of CHB were obtained from the public databases.

Ethylene glycol production has been significantly augmented in recent years due to its various uses. However, conventional oil and coal-based ethylene glycol routes are forcing severe obstacles in production cost and pollutant emissions. Biomass is regarded as a potential contributor to cleaner and sustainable development of the energy sector.

Objective: To explore the antagonistic effect of Fengzhecao extract against human red blood cell (RBC) hemolysis induced by wasp venom.
Methods: Water extract method was used to extract dried Fengzhecao and vacuum-dried to obtain Fengzhecao extract. It was diluted into 1 g/L for next use.
p38 mitogen-activated protein kinases are signaling molecules with major involvement in cancer. A detailed mechanistic understanding of how p38 MAPK family members function is urgently warranted for cancer targeted therapy. The conformational dynamics of the most common member of p38 MAPK family, p38α, are crucial for its function but poorly understood.

Recent studies have shown that CH significantly improves hemodynamic parameters such as right ventricular pressure, right ventricular hypertrophy, and pulmonary vascular remodeling in a rat model of chronic hypoxia-induced pulmonary hypertension (CHPH). These improvements are through the inhibition of NOX4 expression, reactive oxygen species and malondialdehyde production, pulmonary arterial smooth muscle cell (PASMC) proliferation, and collagen accumulation.

Osmotic pressure simulations have recently gained popularity as a means to validate common force fields for biomolecules such as proteins; up to now, however, little such effort has been made to use these methods to validate common force fields for small drug-like molecules. In this work, osmotic coefficients of 16 drug-like molecules were calculated from osmotic pressure molecular dynamics simulations using four common force fields for drug-like molecules: GAFF, CGenFF, OPLS-AA, and PRODRGFF.

Background: The sedative anesthetic, propofol, is a cardioprotective agent for hyperglycemia-induced myocardial hypertrophy and dysfunction in rats. However, the specific protective mechanism has not been clarified.
Methods And Results: In this experiment, we used H9c2 cells subjected to 22 mM glucose lasting for 72 hours as an in vitro model of cardiomyocyte injury by hyperglycemia and investigated the potential mechanism of propofol against hyperglycemic stress in cells.
Ischemia/reperfusion (I/R) injury induces irreversible oxidative stress damage to the cardiac myocytes. Many studies have revealed that propofol alleviates the important organelle-mediated injury from oxidative stress . However, it remains unclear whether propofol prevents I/R-induced DNA damage in cardiomyocytes.
