We investigated underlying mechanism of retinoblastoma-binding protein 6 (Rbbp6)-mediated brain and muscle ARNT-like 1 (Bmal1) ubiquitination in modulating ferroptosis in DITD.
Methods: Spermatogenic cell apoptosis and viability were measured by flow cytometry and cell counting kit 8 (CCK-8), respectively.

Directed alterations of the enzyme's temperature adaptations, such as thermostability and optimal catalytic temperature (T), are usually the way to go in order to meet the applications, however they are limited by the understanding between protein structure and function. Glutamate decarboxylase (GADs) is a common enzyme in the food industry. In this study, we identified and characterized three novel L-glutamate decarboxylases from psychrophilic microorganisms.

Through integrated methods including phylogenetic analysis, molecular docking, and structural analysis, we identified a pivotal amino acid residue, αTrp116, linking the substrate binding pocket and the active site of a NHase from Pseudonocardia thermophila JCM 3095 (PtNHase). This residue acts as a crucial determinant of substrate specificity within the NHase enzyme.

Methods: A streptozotocin (STZ)-induced diabetic model and high glucose (HG)-treated in vitro diabetic model were established.
Iridocyclitis and the use of glucocorticoid medication have been widely studied as susceptibility factors for cataracts. However, the causal relationship between them remains unclear. This study aimed to investigate the causal relationship between the development of iridocyclitis and the genetic liability of glucocorticoid medication use on the risk of senile cataracts occurrence by performing Two-sample Mendelian randomization (MR) analyses.

Meanwhile, as an important foodborne pathogen, the bacterium can survive in various stressful environments and transmits through the fecal-oral route, posing a serious threat to global food safety. To investigate the roles of STM1863, a member of the DUFs protein family, involved in STM environmental adaptation, biofilm formation, and virulence.

In this study, we investigated the genetic characteristics of currently prevalent porcine epidemic diarrhea virus (PEDV) strains in the region. We collected 548 samples from animals with suspected PED on large-scale pig farms in Xinjiang.

The surface morphology and electronic structure of the electrode were characterized with SEM, XRD and XPS. The layered TiCT did not change the structure of β-PbO, and at the same time, it improved the crystallinity of the material and reduced the grains of PbO.

However, when offshore steel is in service for an extended period under conditions of high pressure, extreme cold, and high-frequency impact loads, the weld joints are prone to fatigue failure or even fractures. Addressing these issues, this study designed a narrow-gap laser wire filling welding process and successfully welded a 100-mm new type of ultra-thick offshore steel.

Electroconvulsive therapy (ECT) uses electrical currents to induce brief seizures in the brain, resulting in rapid and potent antidepressant effects. However, owing to misconceptions and controversies, ECT is not as widely used as it could and often faces stigmatization.
