Background: Obesity, a global health problem, is causally implicated in the development of cardiovascular disease. Bariatric surgeries are effective treatment options for obesity; however, the effectiveness of different bariatric surgeries on cardiac structure and function is not fully understood. We undertook a systematic review and network meta-analysis to comprehensively assess this effectiveness.

Objectives: To compare the efficacy of needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training in the treatment of post-stroke cognitive impairment (PSCI).

Methods: A total of 206 patients with PSCI were randomized into a needle retaining group (103 cases, 9 cases dropped out) and an electroacupuncture group (103 cases, 6 cases dropped out). In addition to the conventional basic medical treatment and the rehabilitation treatment, in the needle retaining group, electroacupuncture at Shenting (GV 24) and Baihui (GV 20) was applied, with continuous wave of 50 Hz in the first 15 min and with disperse-dense wave of 2 Hz/50 Hz in the last 15 min, the needles were continuously retained for 1 h after electroacupuncture, during which cognitive training was adopted; in the electroacupuncture group, cognitive training was performed after the same electric stimulation exerted for 30 min, without additional needles retaining.

Article Synopsis
  • - Angiogenesis, the formation of new blood vessels, is crucial for the growth and spread of colorectal cancer (CRC), but the specific mechanisms involved are not fully understood, particularly regarding the role of microRNAs (miRNAs) in this process.
  • - Researchers discovered that CRC cells can secrete a specific miRNA called N-72, which is present at high levels in the serum of CRC patients and helps promote endothelial cell migration and new blood vessel formation.
  • - The study revealed that miRNA N-72 is delivered to endothelial cells through exosomes, disrupting their junctions and enhancing angiogenesis, suggesting it could be a promising therapeutic target and biomarker for CRC.

Catalytic enantioselective transformation of alkynes has become a powerful tool for the synthesis of axially chiral molecules. Most of these atroposelective reactions of alkynes rely on transition-metal catalysis, and the organocatalytic approaches are largely limited to special alkynes which act as the precursors of Michael acceptors. Herein, we disclose an organocatalytic atroposelective intramolecular (4 + 2) annulation of enals with ynamides.

Background: Post-traumatic stress disorder (PTSD) is a mental disorder that can emerge after an individual experiences a traumatic event such as physical abuse, sexual/relationship violence, combat exposure, witnessing death, or serious injury. This study aimed to identify the most suitable drugs for the management of PTSD based on a network meta-analysis (NMA).

Methods: Six databases (Ovid Medline, EMBase, CENTRAL, PsycINFO, Ovid Health and Psychosocial Instruments, and Web of Science) were searched from inception to September 6, 2022.

Our previous studies have confirmed that luteolin (LU) has a good therapeutic effect on obesity and its complications. However, due to its poor water solubility, the bioavailability is low with limited clinical application. Therefore, the water-soluble solid dispersions (SD) of luteolin were prepared with polyvinylpyrrolidone (PVP) (K10, K40 & K90) by solvent evaporation.

This study assessed the efficacy, acceptability, and safety of pharmaceutical management for combat-related post-traumatic stress disorder (PTSD) to provide a clinical decision-making basis for clinicians. A comprehensive search was conducted using Ovid MEDLINE, Ovid EMBASE, Cochrane Library, Scopus, ScienceDirect, and Web of Science for randomized controlled trails (RCTs), which reported pharmaceutical management and placobo for adults with combat-related PTSD, that were published until April 21, 2021. The effectiveness, acceptability, and adverse events (AEs), were designed as interested outcomes.

Chiral Brønsted acid-catalysed asymmetric synthesis has received tremendous interest over the past decades, and numerous efficient synthetic methods have been developed based on this approach. However, the use of chiral Brønsted acids in these reactions is mostly limited to the activation of imine and carbonyl moieties, and the direct activation of carbon-carbon triple bonds has so far not been invoked. Here we show that chiral Brønsted acids enable the catalytic asymmetric dearomatization reactions of naphthol-, phenol- and pyrrole-ynamides by the direct activation of alkynes.

  • The study explores how Japanese whiting in the northwestern Pacific adapt to varying temperatures, focusing on genetic differences between Chinese and Japanese populations.
  • By analyzing 5.48 million SNPs, researchers found significant genetic divergence linked to geographic distance and local environmental adaptations.
  • Key genes related to temperature adaptation and membrane fluidity were identified, highlighting potential evolutionary patterns and different responses to future climate change between the two populations.

Circular RNAs (circRNAs) are a novel class of endogenous non-coding RNA molecules that are extensively expressed in a variety of species. Recently, increasing evidence suggests that circRNAs have vital functions indifferent types of human cancer, such as gastric cancer, papillary thyroid cancer and lung cancer. However, the roles of circRNAs in the development of colorectal cancer (CRC) remain unclear.

Article Synopsis
  • - The study investigates how genetic variations in the mannose-binding lectin 2 (MBL2) gene may influence the risk of developing tuberculosis (TB), analyzing data from 26 case-control studies involving nearly 8,000 TB cases and over 9,000 controls.
  • - Results showed a significant association between specific MBL2 polymorphisms and increased TB risk, particularly among Asian populations, with odds ratios indicating a heightened risk across several statistical models.
  • - The meta-analysis concludes that MBL2 exon 1 polymorphisms could be a relevant genetic factor in TB susceptibility, emphasizing the importance of the source of control samples in understanding these associations.

A novel and efficient scandium-catalyzed oxidative reaction between ynamides and alcohols for the facile synthesis of various α-alkoxyl amides is reported in this paper. The reaction avoids the need for the use of α-diazo carbonyls which are unstable and may cause some safety concerns. Instead, by using alkynes as the starting materials, this protocol features readily available substrates, compatibility with a broad range of functional groups, simple procedure, mild reaction conditions, and high chemoselectivity.

Reactive oxygen species formed within the mammalian cell can produce 8-oxo-7,8-dihydroguanine (8-oxoG) in mRNA, which can cause base mispairing during gene expression. Here we found that administration of 8-oxoGTP in MTH1-knockdown cells results in increased 8-oxoG content in mRNA. Under this condition, an amber mutation of the reporter luciferase is suppressed.
