Tamsulosin ameliorates bone loss by inhibiting the release of Cl through wedging into an allosteric site of TMEM16A.

TMEM16A, a key calcium-activated chloride channel, is crucial for many physiological and pathological processes such as cancer, hypertension, and osteoporosis, etc. However, the regulatory mechanism of TMEM16A is poorly understood, limiting the discovery of effective modulators. Here, we unveil an allosteric gating mechanism by presenting a high-resolution cryo-EM structure of TMEM16A in complex with a channel inhibitor that we identified, Tamsulosin, which is resolved at 2.

Characterizing ADRs of Enfortumab vedotin and Erdafitinib in bladder cancer treatment: a descriptive analysis from WHO-VigiAccess.

Introduction: Enfortumab vedotin (EV) and Erdafitinib are effective therapeutic drugs for bladder cancer patients following post-chemotherapy and immunotherapy. This study assessed adverse drug reactions (ADRs) from both drugs, comparing their safety profiles to guide clinical use.

Methods: A retrospective descriptive analysis was conducted on ADR reports for EV and Erdafitinib from the World Health Organization (WHO)-VigiAccess database.

Bioinformatics analysis reveals potential crosstalk genes and molecular mechanisms between ulcerative colitis and psoriasis.

Ulcerative colitis (UC) and psoriasis are highly correlated clinically; however, it is unclear whether they have a common pathophysiological mechanism. The purpose of this study is to investigate the important molecules and pathways that mediate the coexistence of UC and psoriasis through quantitative bioinformatics analysis of public RNA-sequencing databases. The UC (GSE38713) and psoriasis (GSE30999) datasets were downloaded from the Gene Expression Omnibus database.

Analysis of the Identification Results of Medical Damage in 20 Urological Death Cases.

Objectives: To explore the causes of related medical damage risks and preventive measures by analyzing the identification results of medical damage in 20 urological death cases.

Methods: A retrospective analysis was conducted on 20 death cases of medical damage identification involving urology diagnosis and treatment accepted by the Judicial Appraisal Center, School of Forensic Medicine, Guizhou Medical University, and Academy of Forensic Science from 2010 to 2023.

Results: Among the 20 cases, the male-to-female ratio was 1.

Metabolomic and enzymatic markers reveal critical air exposure threshold for Crassostrea hongkongensis quality.

Post-harvest air exposure is unavoidable during oyster transportation and storage, yet the physiological tolerance limits and underlying metabolic responses of commercially important oyster species remain poorly understood. While previous studies have focused on immediate post-harvest quality changes, there is limited knowledge about the time-dependent metabolic adaptations that determine product quality during extended air exposure. This study investigated the physiological and metabolic responses of Crassostrea hongkongensis during air exposure at 4 °C, focusing on identifying the optimal period for quality preservation.

Anthropogenic activities disturb phytoplankton taxa and functional groups in an urban river.

Anthropogenic activities have substantial impacts on river ecosystems, yet how phytoplankton taxa and functional groups respond to varying levels of anthropogenic activity in urban rivers remains poorly understood. Herein, we investigated the sensitivity of phytoplankton taxa and functional groups to anthropogenic disturbances in the Bahe River, which experiences increased anthropogenic activity intensity from upstream to downstream. We found that both phytoplankton composition and niche breadth exhibited distinct variations among the three reaches with different anthropogenic disturbances.

hUC-MSCs mitigate atherosclerosis induced by a high-fat diet in ApoE mice by regulating the intestinal microbiota.

Background: The mechanism underlying human umbilical cord mesenchymal stem cells (hUC-MSCs) regulating the stability of atherosclerotic plaque was explored by establishing mice models of atherosclerosis induced by a high-fat diet and hUC-MSCs intervention.

Methods: The ApoE mice atherosclerosis model was constructed using a high-fat diet, and mice were divided into a normal diet group (ND), high-fat diet group (HFD), hUC-MSCs treatment group (HFDM), while the blank control (BC) consisted of C57BL/6J mice. After successful establishment of the model, the feces, hearts, and aorta of mice were collected.

CHAC1: a master regulator of oxidative stress and ferroptosis in human diseases and cancers.

CHAC1, an essential regulator of oxidative stress and ferroptosis, is increasingly recognized for its significant roles in these cellular processes and its impact on various human diseases and cancers. This review aims to provide a comprehensive overview of CHAC1's molecular functions, regulatory mechanisms, and effects in different pathological contexts. Specifically, the study objectives are to elucidate the biochemical pathways involving CHAC1, explore its regulatory network, and discuss its implications in disease progression and potential therapeutic strategies.

Glycyrrhizic acid and patchouli alcohol in Huoxiang Zhengqi attenuate intestinal inflammation and barrier injury via regulating endogenous corticosterone metabolism mediated by 11β-HSD1.

Ethnopharmacological Relevance: Ulcerative colitis (UC), a chronic inflammatory bowel disease, has become a significant public health challenge due to the limited effectiveness of available therapies. Huoxiang Zhengqi (HXZQ), a well-established traditional Chinese formula, shows potential in managing UC, as suggested by clinical and pharmacological studies. However, the active components and mechanisms responsible for its effects remain unclear.

Hyperspectral reflectance imaging for visualizing reducing sugar content, moisture, and hollow rate in red ginseng.

Red ginseng (RG) has been traditionally valued in Northeast Asia for its health-enhancing properties. Recent advancements in hyperspectral imaging (HSI) offer a non-destructive, efficient, and reliable method to assess critical quality indicators of RG, such as reducing sugar content (RSC), water content (WC), and hollow rate (HR). This study developed predictive models using HSI technology to monitor these quality indicators over the spectral range of 400-1700 nm.

Analysis of Variable Frequency Stimulation Sacral Neuromodulation for Different Genders: A Chinese Multicentric Prospective Clinical Study.

Aim: Sacral neuromodulation (SNM) is widely recognized as the essential treatment modality for patients suffering from various lower urinary tract disorders, particularly overactive bladder (OAB). This prospective study recruited patients who underwent variable frequency SNM treatment at six Chinese medical centers, aiming to evaluate the gender-specific effects of this intervention and provide precise guidance on its application for clinical management.

Methods: This prospective study was managed by Beijing Hospital, and six Chinese medical centers participated in this prospective research.

Kupffer cells dictate hepatic responses to the atherogenic dyslipidemic insult.

Apolipoprotein-B (APOB)-containing lipoproteins cause atherosclerosis. Whether the vasculature is the initially responding site or if atherogenic dyslipidemia affects other organs simultaneously is unknown. Here we show that the liver responds to a dyslipidemic insult based on inducible models of familial hypercholesterolemia and APOB tracing.

Is Pyrolysis Treatment a Viable Solution to Detoxify Metal(loid)s in Sewage Sludge toward Land Application? Case Studies of Chromium and Zinc.

Metal(loid)s in sewage sludge (SS) are effectively immobilized after pyrolysis. However, the bioavailability and fate of the immobilized metal(loid)s in SS-derived biochar (SSB) following land application remain largely unknown. Here, the speciation and bioavailability evolution of SSB-borne Cr and Zn in soil were systematically investigated by combining pot and field trials and X-ray absorption spectroscopy.
