Association between physical activity and cognitive function in post-menopausal women with high parity: the chain-mediating effects of nutritional status and depression.

Background: It has been reported that the cognitive responses to physical activity (PA) in postmenopausal women vary by parity status, and women with higher parity show a significant association between PA and cognitive function. However, the potential pathways mediating the relationship between PA and cognitive function in women with higher parity remain unclear. The objective of this study was to examine this association in Chinese cohort and further investigate the mediating pathways.

Copper-Catalyzed 1,4-Alkylarylation of 1,3-Enynes with Ethers and Aryl Boronic Acids Enabled via C(sp)-H Functionalization.

Herein, we present a copper-catalyzed, three-component intermolecular 1,4-alkylarylation of 1,3-enynes with ethers and aryl boronic acids. This method, driven by α-C(sp)-H functionalization of the oxygen atom in ethers, regioselectively produces various tetrasubstituted allenes from simple, readily available precursors. Key features include mild reaction conditions and a simple catalytic system.

Tail Anchored protein insertion mediated by CAML and TRC40 links to neuromuscular function in mice.

Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function.

Artificial biomarker-based feedback-regulated personalized and precise thrombolysis with lower hemorrhagic risk.

The body weight-based thrombolytic medication strategy in clinical trials shows critical defects in recanalization rate and post-thrombolysis hemorrhage. Methods for perceiving thrombi heterogeneity of thrombolysis resistance is urgently needed for precise thrombolysis. Here, we revealed the relationship between the thrombin heterogeneity and the thrombolysis resistance in thrombi and created an artificial biomarker-based nano-patrol system with robotic functional logic to perceive and report the thrombolysis resistance of thrombi.
