Gallbladder carcinoma in the era of artificial intelligence: Early diagnosis for better treatment.

Gallbladder carcinoma (GBC) is the most common malignant tumor of biliary tract, with poor prognosis due to its aggressive nature and limited therapeutic options. Early detection of GBC is a major challenge, with most GBCs being detected accidentally during cholecystectomy procedures for gallbladder stones. This letter comments on the recent article by Deqing in the , which summarized the various current methods used in early diagnosis of GBC, including endoscopic ultrasound (EUS) examination of the gallbladder for high-risk GBC patients, and the use of EUS-guided elastography, contrast-enhanced EUS, trans-papillary biopsy, natural orifice transluminal endoscopic surgery, magnifying endoscopy, choledochoscopy, and confocal laser endomicroscopy when necessary for early diagnosis of GBC.

Antibacterial Activity of Crude , , and Methanolic Extracts on serovar Manilae.

Background And Objective: Leptospirosis is a disease caused by pathogenic prevalent in tropical countries like the Philippines. Some studies have shown that the role of currently used antibiotics for leptospirosis is unclear since trials have found no significant benefit to patient outcomes compared to placebo. This signals the need for alternative therapies, such as herbal medicines, which may provide effective therapeutic regimens in treating this infection.

Rheumatic Heart Disease Burden in Africa and the Need to Build Robust Infrastructure.

Rheumatic heart disease (RHD) is an important public health problem in Africa. Mapping the epidemiology of RHD involves elucidating its geographic distribution, temporal trends, and demographic characteristics. The prevalence of RHD in Africa varies widely, with estimates ranging from 2.

Effect of chronic total occlusion of coronary arteries on cardiovascular outcomes in patients undergoing transcatheter aortic valve replacement: A systematic review and meta-analysis.

Background: Transcatheter aortic valve replacement (TAVR) has significantly advanced the treatment of severe aortic stenosis (AS), particularly in elderly patients who often have coexisting coronary artery disease (CAD). Chronic total occlusion (CTO), a severe form of CAD, may negatively impact outcomes in TAVR patients, though data are limited. This meta-analysis aims to evaluate the impact of CTO on TAVR outcomes.

Unbalanced long-chain fatty acid beta-oxidation in newborns with cystic fibrosis and congenital hypothyroidism.

Background: Immediately after birth, adaptation to the extrauterine environment includes an upregulation of fatty acid catabolism. Cystic fibrosis and untreated hypothyroidism exert a life-long impact on fatty acid metabolism, but their influence during this transitional period is unknown. Children and adults with cystic fibrosis exhibit unbalanced fatty acid composition, most prominently a relative deficit of linoleic acid.

Application of the DRASTIC Model to Assess the Vulnerability of Groundwater Contamination Near Zaporizhzhia Nuclear Power Plant, Ukraine.

Russia's invasion of Ukraine continues to have a devastating effect on the well-being of Ukrainians and their environment. We evaluated a major environmental hazard caused by the war: the potential for groundwater contamination in proximity to the Zaporizhzhia Nuclear Power Plant (NPP). We quantified groundwater vulnerability with the DRASTIC index, which was originally developed by the United States Environmental Protection Agency and has been used at various locations worldwide to assess relative pollution potential.

Nineteenth-century land use shapes the current occurrence of some plant species, but weakly affects the richness and total composition of Central European grasslands.

Context: Historical land use is thought to have influenced plant community diversity, composition and function through the local persistence of taxa that reflect ecological conditions of the past.

Objectives: We tested for the effects of historical land use on contemporary plant species richness, composition, and ecological preferences in the grassland vegetation of Central Europe.

Methods: We analyzed 6975 vegetation plots sampled between 1946 and 2021 in dry, mesic, and wet grasslands in the borderland between Austria, the Czech Republic, and Slovakia.

Two-dimensional Health State Map to define metabolic health using separated static and dynamic homeostasis features: a proof-of-concept study.

Defining metabolic health is critical for the earlier reversing of metabolic dysfunction and disease, and fasting-based diagnosis may not adequately assess an individual's metabolic adaptivity under stress. We constructed a novel Health State Map (HSM) comprising a Health Phenotype Score (HPS) with fasting features alone and a Homeostatic Resilience Score (HRS) with five time-point features only ( = 30, 60, 90, 180, 240 min) following a standardized mixed macronutrient tolerance test (MMTT). Among 111 Chinese adults, when the same set of fasting and post-MMTT data as for the HSM was used, the mixed-score was highly correlated with the HPS.

Selection of Nonlethal Early Biomarkers to Predict Gilthead Seabream () Growth.

One of the main challenges in aquaculture is the constant search for sustainable alternative feed ingredients that can successfully replace fishmeal (FM) without any negative effects on fish growth and health. The goal of the present study was to develop a toolbox for rapidly anticipating the dynamics of fish growth following the introduction of a new feed; nonlethal, biochemical, and molecular markers that provide insights into physiological changes in the fish. A nutritional challenge by feeding a conventional feed rich in FM protein (FM diet) versus an experimental feed rich in plant protein (PP) and low FM inclusion (PP diet), in 20 different families of gilthead sea bream () was performed.

Infant regulatory problems and the quality of dyadic emotional connection-a proof-of-concept study in a multilingual sample.

Background And Aims: Close autonomic emotional connections with others help infants reach and maintain homoeostasis. In recent years, infant regulatory problems (RPs, i.e.

Reticulocyte Binding Protein Homologue 5 is a target of balancing selection in the population of Papua New Guinea.

Reticulocyte Binding Protein Homologue (RH5), a leading malaria vaccine candidate, is essential for erythrocyte invasion by the parasite, interacting with the human host receptor, basigin. RH5 has a small number of polymorphisms relative to other blood-stage antigens, and studies have shown that vaccine-induced antibodies raised against RH5 are strain-transcending, however most studies investigating RH5 diversity have been done in Africa. Understanding the genetic diversity and evolution of malaria antigens in other regions is important for their validation as vaccine candidates.

Manipulation of mitochondrial poly(A) polymerase family proteins in impacts mRNA termini processing.

RNA-specific nucleotidyltransferases (rNTrs) add nontemplated nucleotides to the 3 end of RNA. Two noncanonical rNTRs that are thought to be poly(A) polymerases (PAPs) have been identified in the mitochondria of trypanosomes - KPAP1 and KPAP2. KPAP1 is the primary polymerase that adds adenines (As) to trypanosome mitochondrial mRNA 3 tails, while KPAP2 is a non-essential putative polymerase whose role in the mitochondria is ambiguous.

Pathogen presence, prevalence, and diversity in and mammal hosts at their expanding northern range limits.

With climate and land use changes, tick-borne pathogens are expected to become more widely distributed in Canada. Pathogen spread and transmission in this region is modulated by changes in the abundance and distribution of tick and host populations. Here, we assessed the relationships between pathogens detected in and mammal hosts at sites of different levels of disease risk using data from summer field surveys in Ontario and Quebec, Canada.

Activation of the 26S Proteasome to Reduce Proteotoxic Stress and Improve the Efficacy of PROTACs.

The 26S proteasome degrades the majority of cellular proteins and affects all aspects of cellular life. Therefore, the 26S proteasome abundance, proper assembly, and activity in different life contexts need to be precisely controlled. Impaired proteasome activity is considered a causative factor in several serious disorders.

Molecular and Immunological Properties of a Chimeric Glycosyl Hydrolase 18 Based on Immunoinformatics Approaches: A Design of a New Anti- Vaccine.

Leishmaniasis is a chronic inflammatory zoonotic illness caused by protozoan flagellates belonging to the genus. Current data suggest that over 1 billion people worldwide are susceptible to infection, primarily in tropical and subtropical countries, where up to 2 million new cases are reported annually. Therefore, the development of a vaccine is crucial to combating this disease.

Molecular Pharmacology of Dasatinib Provides Unique Insights into the Mechanistic Basis of Success and Failure of Targeted Cancer Therapy.

Despite the enthusiasm for targeted cancer therapies in preclinical studies and the success of a select few drugs, many promising drug candidates fail in clinical trials. The gap between preclinical promise and clinical outcomes underscores the need to investigate factors influencing the success or failure of targeted therapies. Dasatinib, an inhibitor of Abl and Src protein tyrosine kinases, is highly effective toward chronic myeloid leukemia (CML) by targeting BCR-Abl, but it is ineffective against solid tumors when targeting Src kinases.

Non-random mating behaviour between diverging littoral and pelagic three-spined sticklebacks in an invasive population from Upper Lake Constance.

Adaptive divergence and increased genetic differentiation among populations can lead to reproductive isolation. In Lake Constance, Germany, a population of invasive three-spined stickleback () is currently diverging into littoral and pelagic ecotypes, which both nest in the littoral zone. We hypothesized that assortative mating behaviour contributes to reproductive isolation between these ecotypes and performed a behavioural experiment in which females could choose between two nest-guarding males.

Urbanization enhances body condition, but not innate immune defences, in a common waterbird.

There is a growing body of evidence that urbanization can affect body condition and immune function in wild birds, although these effects may be complex and taxa-specific. Here, we assessed the effects of urbanization on body condition (size-corrected body mass and haemoglobin concentration) and innate immune defences (haemolysis-haemagglutination assay, haptoglobin concentration and bacterial killing assay) in 136 Eurasian coots () from three urban and three non-urban populations across Poland. We also quantified the heterophil to lymphocyte ratio to control for the potential effect of physiological stress on immune defences.

Female reproductive ageing persists despite high infanticide risk in chacma baboons and geladas.

Across mammals, fertility and offspring survival are often lowest at the beginning and end of females' reproductive careers. However, extrinsic drivers of reproductive success-including infanticide by males-could stochastically obscure these expected age-related trends. Here, we modelled reproductive ageing trajectories in two cercopithecine primates that experience high rates of male infanticide: the chacma baboon () and the gelada ().

Morphological change in an isolated population of red squirrels () in Britain.

The mechanical properties of dietary items are known to influence skull morphology, either through evolution or by phenotypic plasticity. Here, we investigated the impact of supplementary feeding of peanuts on the morphology of red squirrels () from five populations in Britain (North Scotland, Borders, Jersey and two temporally distinct populations from Formby (Merseyside)). Stable isotope analysis confirmed dietary ecology in 58 specimens.

JARID1D-dependent androgen receptor and JunD signaling activation of osteoclast differentiation inhibits prostate cancer bone metastasis through demethylating H3K4.

Bone metastasis and skeletal-related complications are primary causes of mortality in advanced-stage prostate cancer (PCa). Epigenetic regulation, particularly histone modification, plays a key role in this process; however, the underlying mechanisms remain elusive. In mouse models, JARID1D was an important mediator of both visceral and bone metastases.

Revisiting the unobtrusive role of exogenous stem cells beyond neural circuits replacement in spinal cord injury repair.

Stem cell transplantation is a promising strategy to establish neural relays in situ for spinal cord injury (SCI) repair. Recent research has reported short-term survival of exogenous cells, irrespective of immunosuppressive drugs (ISD), results in similar function recovery, though the mechanisms remain unclear. This study aims to validate this short-term repair effect and the potential mechanisms in large animals.

Unveiling urinary extracellular vesicle mRNA signature for early diagnosis and prognosis of bladder cancer.

Bladder cancer (BC) ranks as one of the most prevalent cancers. Its early diagnosis is clinically essential but remains challenging due to the lack of reliable biomarkers. Extracellular vesicles (EVs) carry abundant biological cargoes from parental cells, rendering them as promising cancer biomarkers.

Cure for tantrums? Longitudinal associations between parental digital emotion regulation and children's self-regulatory skills.

Introduction: Parents often use digital devices to regulate their children's negative emotions, e.g., to stop tantrums.

Translation, cross-cultural adaptation and validation of the universal Welch Emotional Connection Screen using primary and bilingual Spanish-speaking coders of videotaped mother-child interactions.

Introduction: Using clear explicit translatable language, we translated the Welch Emotional Connection Screen into a new universal language instrument, the . In this study, we had two aims: Aim 1 was to establish of the uWECS by comparing scores coded by primary Spanish-speaking coders using the Spanish translation of the uWECS to scores coded by bilingual, secondary Spanish-speaking coders using the oWECS. Aim 2 was to establish the in terms of oWECS and uWECS performance in tracking change in autonomic emotional connection (AEC) during the course of an intervention among preschool aged children.
