Heat-Inactivated FRT4 Alleviates Diet-Induced Obesity via Gut-Liver Axis Reprogramming.

Obesity and related metabolic disorders are major global health challenges. Postbiotics, such as heat-inactivated probiotics, have attracted attention for their improved safety, stability, and potential metabolic benefits compared to live probiotics. However, the comparative anti-obesity effects and mechanisms of live versus heat-inactivated FRT4 remain unclear, so this study systematically evaluated their effects and mechanisms in high-fat-diet-induced obese mice.

Probiotic Potentials and Protective Effects of LA-1 Against High-Fat Diet-Induced Obesity in Mice.

: Obesity is increasingly recognized as a global health concern due to its association with metabolic disorders and gut microbiota dysbiosis. While probiotics offer promise in regulating gut microbiota and improving host metabolism, strain-specific effects remain underexplored, particularly for canine-derived probiotics. This study aimed to isolate and characterize a novel probiotic strain, LA-1, and evaluate its anti-obesity effects and underlying mechanisms using a high-fat diet (HFD)-induced obese mouse model.

ZY15 Alleviates Intestinal Inflammation and Barrier Dysfunction via AKT/mTOR/HIF-1α/RORγt/IL-17 Signaling and the Gut Microbiota in ETEC K88-Challenged .

, a recognized probiotic, improves intestinal health in animals, but the mechanism remains unclear. This study investigates the mechanisms by which ZY15, isolated from healthy pig feces, mitigates intestinal barrier damage and inflammation caused by oxidative stress in Enterotoxigenic (ETEC) K88-challenged mice. The results indicated that ZY15 increased antioxidant capacity by reducing serum reactive oxygen species (ROS) and superoxide dismutase (SOD) levels.

In Vitro Evaluation of Probiotic Activities and Anti-Obesity Effects of EF-1 in Mice Fed a High-Fat Diet.

This research sought to assess the anti-obesity potential of EF-1. An extensive and robust in vitro methodology confirmed EF-1's significant potential in combating obesity, probably due to its excellent gastrointestinal tract adaptability, cholesterol-lowering property, bile salt hydrolase activity, α-glucosidase inhibition, and fatty acid absorption ability. Moreover, EF-1 exhibited antimicrobial activity against several pathogenic strains, lacked hemolytic activity, and was sensitive to all antibiotics tested.

Causal effect of age first had sexual intercourse and lifetime number of sexual partners on cervical cancer.

Objective: In this study, we aimed to investigate whether age first had sexual intercourse (AFSI) and lifetime number of sexual partners (LNSP) have a direct causal effect on cervical cancer by Mendelian randomization (MR) analysis.

Methods: Four approaches were used for MR Analysis, including MR-Egger, weighted method, weighted median, and inverse variance weighted (IVW). MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) as well as MR-Egger regression analysis were conducted to detect whether there was pleiotropy between IVs and outcome, and the outlier SNPs can be detected by MR-PRESSO.

Immune checkpoint inhibitors in advanced and recurrent/metastatic cervical cancer.

Cervical cancer (CC) poses a serious threat to women's health. Although many early-stage patients have a good prognosis, there are still a lack of effective therapies for advanced and recurrent/metastatic CC. In this context, immunotherapy and immune checkpoint inhibitors (ICIs) are particularly likely to play a role in the treatment of cervical tumors in a variety of disease settings.

Effects of targeting signal mutations in a mitochondrial presequence on the spatial distribution of the conformational ensemble in the binding site of Tom20.

The 20-kDa TOM (translocase of outer mitochondrial membrane) subunit, Tom20, is the first receptor of the protein import pathway into mitochondria. Tom20 recognizes the mitochondrial targeting signal embedded in the presequences attached to mature mitochondrial proteins, as an N-terminal extension. Consequently, ~1,000 different mitochondrial proteins are sorted into the mitochondrial matrix, and distinguished from non-mitochondrial proteins.

Tumor mutation burden in connection with immune-related survival in uterine corpus endometrial carcinoma.

Background: UCEC is the most common gynecological malignancy in many countries, and its mechanism of occurrence and development is related to tumor mutation burden (TMB) and immune cell infiltration. Therefore, it is necessary to systematically explore the TMB-related gene profile in immune cells to improve the prognosis of UCEC.

Methods: We integrated TMB-related genes with basic clinical information of UCEC patients based on TCGA dataset.

Lymphadenectomy and prognosis for elderly females with stage I endometrioid endometrial cancer.

Purpose: The potential therapeutic benefits of lymphadenectomy in endometrial cancer (EC) patients are still ambiguous. Therefore, a population-based retrospective analysis was conducted to determine the association between lymphadenectomy and survival in elderly female patients with stage I endometrioid EC.

Methods: The Surveillance, Epidemiology, and End Results (SEER) program database was retrospectively analyzed, and data of 63,372 female patients with early-stage type I EC from 1988 to 2013 were collected.

General Self-Template Synthesis of Transition-Metal Oxide and Chalcogenide Mesoporous Nanotubes with Enhanced Electrochemical Performances.

The development of a general strategy for synthesizing hierarchical porous transition-metal oxide and chalcogenide mesoporous nanotubes, is still highly challenging. Herein we present a facile self-template strategy to synthesize Co3 O4 mesoporous nanotubes with outstanding performances in both the electrocatalytic oxygen-evolution reaction (OER) and Li-ion battery via the thermal-oxidation-induced transformation of cheap and easily-prepared Co-Asp(cobalt-aspartic acid) nanowires. The initially formed thin layers on the precursor surfaces, oxygen-induced outward diffusion of interior precursors, the gas release of organic oxidation, and subsequent Kirkendall effect are important for the appearance of the mesoporous nanotubes.
