Type 3 resistant starch (RS3) regulates diet-related metabolic diseases by promoting intestinal short-chain fatty acids (SCFAs) and lactate production, and facilitating microbial lactate-to-butyrate fermentation. However, its precise in vivo mechanism remains unclear. Therefore, we studied the effects of type 3 lotus seed resistant starch (LRS3) and sodium lactate (SL) on colonic microbiota composition, metabolism, and lipid parameters.

This study aims to evaluate HBsAg loss in individuals with HIV/HBV coinfection and explore the association of clinical variables with this outcome.
Methods: We enrolled 138 individuals coinfected with HIV/HBV and 480 HBV mono-infected individuals who initiated antiviral treatment.
Multifunctional memristors with a high memory density, low power consumption, flexibility, programmability, and environmental robustness are essential for next-generation memories. In this work, a titanocene-polysulfide complex (CpTiS) with strong S···S interactions and hydrogen bonds was synthesized and integrated with TiO to create a novel Cu/TiO/CpTiS/Ag memristor. This device shows bipolar nonvolatile memory performance with a remarkable ON/OFF ratio (10), low switching voltages (, -0.

Recent research has identified that plants transfer their small RNAs and microRNAs into fungal pathogens to suppress infection. However, whether and how plants send defense proteins into pathogens remains unknown.

However, mechanisms underlying phyB photoactivation and PIF binding for signal transduction remain elusive. Here, we report the cryo-electron microscopy (cryo-EM) structures of the photoactivated phyB or the constitutively active phyB mutant in complex with PIF6, revealing a similar trimer.

Aim: The study sought to assess the levels of sexual difficulties and explore the associations between sexual difficulties, mental health, and HRQoL in HIV-positive MSM.
Methods: A cohort of 475 HIV-positive MSM was studied from January 2017 to December 2021.
Aim: To comprehensively identify the status and influencing factors on maternal health literacy among postpartum women in Guangzhou urban villages.
Design: An explanatory sequential mixed-method research was conducted from November 2021 to July 2022.
Methods: The quantitative survey was conducted among postpartum women in Guangzhou urban villages using the convenience sampling principle, and a questionnaire survey was used to reflect the status and influencing factors on maternal health literacy.
Purpose: This study investigated whether RNA-Seq-based endometrial receptivity test (rsERT)-which provides precision for the optimal hour of the window of implantation (WOI)-can improve clinical outcomes of frozen embryo transfer (FET) cycles in patients with a history of repeated implantation failure (RIF).
Methods: Patients with a history of RIF who received at least one autologous high-quality blastocyst during the subsequent FET cycle were retrospectively enrolled and divided into two groups: rsERT and FET, comprising patients who underwent rsERT-guided pET (n=115) and standard FET without rsERT (n=272), respectively.
Results: In the rsERT group, 39.

Accurate prediction of drug-drug interactions (DDIs) plays an important role in improving the efficiency of drug development and ensuring the safety of combination therapy. Most existing models rely on a single source of information to predict DDIs, and few models can perform tasks on biomedical knowledge graphs. This paper proposes a new hybrid method, namely Knowledge Graph Representation Learning and Feature Fusion (KGRLFF), to fully exploit the information from the biomedical knowledge graph and molecular structure of drugs to better predict DDIs.

Multiple studies were recently undertaken to examine the factors influencing the formation of persisters and the underlying process, with a primary focus on Gram-negative bacteria and (Gram-positive bacteria). Enterococcus faecalis () is capable of causing a variety of infectious diseases, but there have been few studies of persisters.

However, the biological correlates underlying this epidemiological finding, especially the functional basis at the synapse level, have been elusive. This study reveals that motor skill performance examined via rotarod, beam walking and pole tests is impaired in aged mice.

Methods: A total of 150 adult renal transplant recipients who underwent PTA were randomized to either the experimental group or the control group.
Background: The incidence of mental health problems among medical graduate students is much higher than among students of other disciplines. This can have adverse consequences for the medical students themselves as well as their future patients. This study aims to understand the pressures faced by Chinese medical students and the current status of mental health education.

Patients And Methods: A total of 485 PLWH were enrolled. These participants were categorized into two groups based on the estimated pulse wave velocity (ePWV) level.
Objective: Retention of weight gained over pregnancy increases the risk of long-term obesity and related health concerns. While many risk factors for this postpartum weight retention have been examined, the role of mode of delivery in this relationship remains controversial. We carried out a systematic review and meta-analysis to determine the effect of mode of delivery on postpartum weight retention.

Results: We identified 14 CYCD genes in the rice genome and confirmed the presence of characteristic cyclin domains in each.
Background: Due to the chronic nature of HIV, mental health has become a critical concern in people living with HIV (PLWHIV). However, little knowledge exists about the association between fear of progression (FoP) and medical coping modes (MCMs) in PLWHIV in China.
Methods: A cohort of 303 PLWHIV were consecutively enrolled and their demographic, clinical and psychological information was collected.

However, curiosity declines as humans age, and the decline even positively predicts the extent of cognitive decline in Alzheimer's disease patients. Therefore, determining the underlying mechanism, which is currently unknown, is an urgent task for the present aging society that is growing at an unprecedented rate.
