From Radical Coupling to Enantioselective Controlled Protonation: Advancing Precise Construction of Stereocenters.

Recent advancements in green and sustainable platforms, particularly visible light-driven photocatalysis, have spurred significant progress in radical chemistry, enabling the efficient synthesis of important molecules from simple and readily available feedstocks under mild conditions. However, the rapid orbital flipping and high reactivity of radicals pose substantial challenges for achieving precise enantiocontrol in stereocenter formation via radical coupling. In this study, we present a generic and efficient strategy that modulates this elusive approach, facilitating enantiocontrollable protonation through 1,3-boron migration.

A Combination of Conventional Transconjunctival Lower Blepharoplasty and Percutaneous Nanofat Grafting in a Young Chinese Population With Eyelid Bags and Tear Trough Deformities.

Objective: A simple and minimally invasive combined procedure, including transconjunctival orbital fat removal and transcutaneous resected orbital fat injection, was performed based on the anatomical characteristics of the lower eyelids in our young Chinese patients. Our study aimed to investigate the efficacy and safety of this procedure in our study population.

Methods: In our retrospective study, a total of 183 consecutive patients underwent a combination of traditional transconjunctival blepharoplasty and nanofat grafting between February 2020 and June 2024.

Ascaris lumbricoides a rare cause gastric perforation: a case report and brief literature review.

(AL), a prevalent nematode causing ascariasis, infects millions worldwide, with a higher risk in preschool and school-aged children. Though infections are usually mild, rare and life-threatening complications like gastrointestinal perforation exist. This article documents a case involving a 61-year-old deaf-mute man who presented with a month-long history of epigastric pain accompanied by nausea, anorexia, and constipation.

Probiotic LV149 enhances gut repair, modulates microbiota, and alters transcriptome in DSS-induced colitis mice.

Purpose: Gut microbiota dysbiosis significantly impacts ulcerative colitis (UC) progression and exacerbation. Probiotics show promise in UC management. This study evaluated the effects of different doses of LV149, an aquatic-derived probiotic, on gut injury repair in male C57BL/6 mice with dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) and investigated the underlying mechanisms.

Dual-Asymmetric Solid Additive Enables Eco-friendly All-Polymer Solar Cells with Over 19% Efficiency and Excellent Stability.

The optimization of morphology in all-polymer solar cells (all-PSCs) often relies on the use of solvent additives. However, their tendency to remain trapped in the device due to high boiling points leads to performance degradation over time. In this study, we introduce a novel approach involving the design and synthesis of one dual-asymmetric solid additive featuring mono-brominated-asymmetric dithienothiophene (SL-1).
