Purpose: Lactobacillus casei Zhang (LCZ) has health benefits, such as the ability to improve blood glucose levels in individuals with type 2 diabetes mellitus (T2DM). However, little is known about the effects of LCZ on brain structural plasticity and cognitive function in T2DM. The aims of this study were to determine whether LCZ can prevent and alleviate brain damage and memory impairment in T2DM, and to understand the mechanisms underlying the effects of LCZ in T2DM.

Herpes simplex virus type 1 (HSV-1) is the leading pathogen in the maxillo-facial region, affecting millions of individuals worldwide. Its periodic reactivation aligns with the most common course pattern of periodontal disease. The present study used RNA sequencing to investigate the transcriptomes of human gingival fibroblasts (HGFs) following HSV-1 infection from the early to late stages (12-72 h).

RAS is a common driver of cancer that was considered undruggable for decades. Recent advances have enabled the development of RAS inhibitors, but the efficacy of these inhibitors remains limited by resistance. Here, we developed a pan-RAS inhibitor, ADT-007, that binds nucleotide-free RAS to block GTP activation of effector interactions and MAPK/AKT signaling, resulting in mitotic arrest and apoptosis.

Background And Objective: The neutrophil percentage to albumin ratio (NPAR) is an emerging, costimulatory indicator of inflammation that is associated with a variety of diseases, such as non-alcoholic fatty liver disease, liver fibrosis, stroke, and cardiovascular disease. However, the relationship between NPAR and gallstones (GS) has not yet been explored. Therefore, this study aimed to evaluate the association of the NPAR with the odds of GS and the age of patients at the time of their first GS surgery.

Tumors occurring along the hypothalamus-pituitary axis receive axonal projection from neuroendocrine neurons, but it remains unclear whether neuroendocrine neuronal activity drives tumor expansion. Craniopharyngioma is a common suprasellar tumor with a propensity for invading the hypothalamus, leading to devastating endocrine and metabolic disorders. Here, we developed two autochthonous animal models that faithfully recapitulate the molecular pathology, clinical manifestations, and transcriptomic profiles of papillary craniopharyngioma.

Quaternary ammonium compounds (QACs) served as broad spectrum antimicrobial agents are widely applied for surface disinfection, skin and mucous disinfection, and mouthwash. The daily applications of QACs have significantly increased, especially during the COVID-19 pandemic. However, the environmental residues of QACs have demonstrated harmful impacts on the environment, leading to an increase in environmental contamination, resistant microbes and disruption of microecology.

Tuberculosis (TB), primarily caused by () and (), remains the leading cause of death from a single infectious agent globally. Intracellular survival is crucial for their virulence; yet, the underlying mechanisms are not fully understood. This study aimed to demonstrate the significance of a previously unannotated bovine gene ENSBTAG00000011305 in intracellular survival.

The scaffolding function of receptor interacting protein kinase 1 (RIPK1) confers intrinsic and extrinsic resistance to immune checkpoint blockades (ICBs) and emerges as a promising target for improving cancer immunotherapies. To address the challenge posed by a poorly defined binding pocket within the intermediate domain of RIPK1, here we harness proteolysis targeting chimera (PROTAC) technology to develop a RIPK1 degrader, LD4172. LD4172 exhibits potent and selective RIPK1 degradation both in vitro and in vivo.

Solid-state Li-ion batteries are attracting attention for their enhanced safety features, higher energy density, and broader operational temperature range compared to systems based on liquid electrolytes. However, current solid-state Li-ion batteries face performance challenges, such as suboptimal cycling and poor rate capabilities, often due to inadequate interfacial contact between the solid electrolyte and electrodes. To address this issue, we incorporated a gallium-indium (Ga-In) liquid metal as the anode in a solid-state Li-ion battery setup, employing LiPSCl as the solid electrolyte.

Objectives: This study aims to elucidate the role of cAMP responsive element binding protein 3 like 4 (CREB3L4) in the pathogenesis of lung adenocarcinoma (LUAD) and to provide new insights and approaches for its effective treatment. An analysis was conducted on the expression and prognostic implications of CREB3L4 in LUAD.

Methods: Potential downstream target genes regulated by CREB3L4 were identified through chromatin immunoprecipitation assay sequencing and mRNA sequencing analyses, and the regulatory relationship, mechanism, and prognostic significance of the identified target gene in LUAD were subsequently confirmed.

Background: The cardiovascular risk profiles of trastuzumab drug conjugates (T-DCs) in the treatment of Human Epidermal Growth Factor Receptor 2 (HER2)-positive breast cancer are uncertain. This study analyzed real-world adverse events data from the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to investigate the association between T-DCs and major adverse cardiovascular events (MACE).

Methods: We searched the FAERS database for reports of cardiovascular adverse events in patients with HER2-positive breast cancer receiving trastuzumab, ado-trastuzumab emtansine (T-DM1), and trastuzumab deruxtecan (T-Dxd).

Thirteen abietane-type diterpenoids, including seven previously undescribed compounds and six known analogs, were isolated from the root and aerial parts of Phlegmariurus carinatus. Their structures were elucidated by comprehensive spectroscopic data analysis (UV, IR, NMR, and HRESIMS) and quantum chemical calculations (calculated ECD or C NMR). Notably, these compounds exhibited high structural diversity.

Background: The lengthy duration and high frequency of drug resistance associated with currently used antimycobacterial drug treatments have intensified the need for alternative therapies against Mycobacterium tuberculosis, the causative agent of TB.

Methods: MICs and intracellular macrophage cfu counts were tested to evaluate the antibacterial activity of nintedanib and pirfenidone against drug-susceptible and -resistant M. tuberculosis.

Poor O tolerance and high reaction temperature of the conventional oxygen carriers challenge the direct utilization of impure CO via chemical looping. Here, Pt-Ni bimetallic Ce-based oxygen carriers with excellent O tolerance are developed for highly efficient reduction of O-containing CO at low temperatures. At a temperature as low as 700 °C, high CO conversion (≈92%) is obtained over 0.

Article Synopsis
  • - The study aimed to assess the prevalence of frailty and its effects on quality of life in older breast cancer patients in China, a topic not well-explored previously.
  • - Conducted as a multi-centre registry study, data was gathered from three hospitals between October 2021 and July 2023, focusing on patients over 65 who completed various assessment scales for frailty, mental health, and quality of life.
  • - Among the 946 participants, 8.8% were identified as frail, with higher rates seen in those aged 75 or older and those with advanced cancer or mental health issues; significant predictors of frailty included older age, advanced tumors, anxiety, and depression.
