Effects of high-intensity interval training in a cold environment on arterial stiffness and cerebral hemodynamics in sedentary Chinese college female students post-COVID-19.

Many patients with COVID-19 experience increased arterial stiffness and abnormal cerebral hemodynamics. Although previous studies have explored the effects of cold environments on cardiovascular health and cerebral hemodynamics, there is still no research on the changes in cardiovascular and cerebral hemodynamics in sedentary female students recovering from COVID-19 while performing high-intensity interval training (HIIT) in cold environments. This study investigates the effects of 1 week of HIIT in a cold environment on cerebral hemodynamics and arterial stiffness (AS) in sedentary female college students, providing new insights into the pathophysiological mechanisms in this specific context.

Discovery of JAB-3312, a Potent SHP2 Allosteric Inhibitor for Cancer Treatment.

As an oncogenic phosphatase, SHP2 acts as a converging node in the RTK-RAS-MAPK signaling pathway in cancer cells and suppresses antitumor immunity by passing signals downstream of PD-1. Here, we utilized the extra druggable pocket outside the previously identified SHP2 allosteric tunnel site by the (6,5 fused), 6 spirocyclic system. The optimized compound, , exhibited a SHP2 binding of 0.

Whole-exome sequencing analysis identifies novel variants associated with Kawasaki disease susceptibility.

Background: Kawasaki disease (KD) is an acute pediatric vasculitis affecting genetically susceptible infants and children. Although the pathogenesis of KD remains unclear, growing evidence links genetic susceptibility to the disease.

Methods: To explore the genes associated with susceptibility in KD, we applied whole-exome sequencing to KD and control subjects from Yunnan province, China.

[Anatomic study and clinical application of thinned posterior tibial artery perforator flap].

Objective: To explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.

Methods: Six fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed.

[Construction and identification of small interfering RNA expression plasmid targeting Sox9 and the function to cell growth and apoptosis of human chondrosarcoma cells HTB94].

Objectives: To construct small interfering (siRNA) Sox9 expression plasmid and transfer it into human chondrosarcoma cells HTB-94, and to check the mRNA and protein expression of Sox9 and cell growth and apoptosis of HTB-94 human chondrosarcoma cells.

Methods: siRNA(Sox9) expression plasmid was designed and synthesized. And it was transferred into HTB-94 human chondrosarcoma cells.
