Synthesis of α-Chloroboronic Esters via Photoredox-Catalyzed Chloro-Alkoxycarbonylation of Vinyl Boronic Esters.

α-Chloroboronic esters are a class of stable multifunctional molecules that show unique applications in pharmaceutical science and organic chemistry. Despite their apparent utility, the synthetic methods of these compounds remain limited. Herein, a novel strategy for the efficient synthesis of α-chloroboronic esters is developed via photoredox-catalyzed chloro-alkoxycarbonylation of vinyl boronic esters.

[Characteristics of O Production in the Western Suburb of Hefei in Summer Based on the Observation of Total Peroxy Radical].

In August 2020, the observations of total peroxy radical concentrations were carried out in the western suburb site of Hefei using a peroxy radical chemical amplifier (PERCA) instrument. The ozone production and its sensitivity were characterized with the measured O and its precursors. The results showed that the daily variation in total peroxy radical concentrations exhibited an obvious convex tend, with the highest value at approximately 12:00; the average peak peroxy radical concentration was 43.

Integrative analysis reveals a lineage-specific circular RNA landscape for adipo-osteogenesis of human mesenchymal stem cells.

Background: The balance between osteogenesis and adipogenesis of mesenchymal stem cells (MSCs) is critical to skeletal development and diseases. As a research hotspot, circular RNAs (circRNAs) have expanded our understanding of a hidden layer of the transcriptome. Yet, their roles during adipo-osteogenesis remain poorly described.

[Effects of Balance Acupuncture Combined with Motor Relearning for Lower Limb Motor Function of Stroke Patients with Hemiplegia].

Objective: To investigate the effect of balance acupuncture combined with motor relearning training on lower limb motor function in stroke patients with hemiplegia.

Methods: Eighty stroke patients were randomly assigned to motor relearning training group and balance acupuncture plus motor relearning group (＝40 cases in each). The motor relearning training program consisting of upper-limb functional training, lying supine, bedside sitting, sitting-balancing, standing up and down, standing-balancing, walking, orofacial functional training, etc.

[Improvement of Upper Limb and Hand Functions of Stroke Patients by Balancing Acupuncture Combined with Motor Relearning Training].

Objective: To observe the therapeutic effect of balance acupuncture combined with motor relearning training for upper limb and hand functions of stroke patients.

Methods: Sixty-two stroke patients were randomly divided into balance acupuncture group (＝31) and routine acupuncture group (＝31). For patients of the balance acupuncture group, Piantan, Jiantong and Wantong points on the healthy side were used.
