Herein, we report the first example that P(O)-H species including -phosphonates and -phosphine oxides could participate in a highly regioselective 1,4-addition to in situ generated 1-benzopyrylium ion from C3-substituted 2-chromene hemiketals, which provides a brand-new and effective approach for the synthesis of C4-phosphorylated 4-chromenes with diverse C3-functionality (ketone, ester, sulfonyl, aryl, and alkyl groups). In total, the reaction features the use of inexpensive Zn(ClO)·6HO as a catalyst, low catalyst loading (only 5 mol %), mild reaction conditions (60 °C, 10 min to 24 h), and broad substrate scope (46 examples) as well as good to high yields (>90% yield on average). More importantly, mechanistic experiments demonstrated the essential role of the C3-substituent on 2-chromene hemiketals in stabilizing the in situ generated 1-benzopyrylium ion and the regioselective 1,4-addition control.

Background: This study investigates the therapeutic efficacy of dynamic neuromuscular stabilization (DNS) technology paired with Kinesio Taping in patients with persistent nonspecific low back pain, as well as the effect on neuromuscular function and pain self-efficacy.
Methods: A randomized controlled clinical study was conducted to collect clinical data on DNS combined with KT for the treatment of chronic nonspecific low back pain from November 2023 to April 2024. The inclusion criteria were patients with chronic nonspecific lower back pain, aged between 18 and 30 years old, and without serious underlying medical conditions, such as cardiac disease, hypertension, and diabetes.

Introduction: The purpose of this study was to review rates of infection after civilian ballistic fractures and assess the effect of early antibiotic administration (EAA) on infection rates.
Methods: This was a retrospective cohort study done at an urban Level 1 Trauma Center. Patients ages 16 years and older with ballistic orthopaedic extremity injuries between May 2018 and December 2020 were enrolled.

Preharvest sprouting (PHS) is an unfavorable trait in cereal crops that significantly reduces grain yield and quality. However, the regulatory mechanisms underlying this complex trait are still largely unknown. Here, 276 rice accessions from the 3000 Rice Genomes Project were used to perform a genome-wide association study.

Objective: Spinal fusion is a commonly performed surgical procedure used to relieve pain, deformity, and instability of various spinal pathologies. Although there have been attempts to standardize spinal fusion assessment radiologically, there is currently no unified definition that also considers clinical symptomology. This review attempts to create a more holistic and standardized definition of spinal fusion.
