Synergistic regulation of colon microflora and metabolic environment by resistant starch and sodium lactate in hyperlipidemic rats.

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.

Engineering Titanium Dioxide/Titanocene-Polysulfide Interface for Flexible, Optical-Modulated, and Thermal-Tolerant Multilevel Memristor.

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.

Rice extracellular vesicles send defense proteins into fungus Rhizoctonia solani to reduce disease.

The exchange of molecular information across kingdoms is crucial for the survival of both plants and their pathogens. 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.

Light-induced remodeling of phytochrome B enables signal transduction by phytochrome-interacting factor.

Phytochrome B (phyB) and phytochrome-interacting factors (PIFs) constitute a well-established signaling module critical for plants adapting to ambient light. 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.

Precise hourly personalized embryo transfer significantly improves clinical outcomes in patients with repeated implantation failure.

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.

KGRLFF: Detecting Drug-Drug Interactions Based on Knowledge Graph Representation Learning and Feature Fusion.

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.

Pheromone cCF10 inhibits the antibiotic persistence of by modulating energy metabolism.

Introduction: Bacterial resistance presents a major challenge to both the ecological environment and human well-being, with persistence playing a key role. 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.

Reduced inhibitory synaptic transmission onto striatopallidal neurons may underlie aging-related motor skill deficits.

Human beings are living longer than ever before and aging is accompanied by an increased incidence of motor deficits, including those associated with the neurodegenerative conditions, Parkinson's disease (PD) and Huntington's disease (HD). 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.

Effect of mode of delivery on postpartum weight retention: A systematic review and meta-analysis.

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.

Reduction in the activity of VTA/SNc dopaminergic neurons underlies aging-related decline in novelty seeking.

Curiosity, or novelty seeking, is a fundamental mechanism motivating animals to explore and exploit environments to improve survival, and is also positively associated with cognitive, intrapersonal and interpersonal well-being in humans. 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.
