SMAP3-ID for Identification of Endogenous Protein-Protein Interactions Reveals Regulation of Mitochondrial Activity by Lamins.

Proteins regulate biological functions through the formation of distinct protein complexes. Identification and characterization of these protein-protein interactions are critical to deciphering their mechanism of action. Different antibody-based or cross-linking-based methods have been developed to identify the protein-protein interactions.

Peptide Backbone Cleavage and Transamidation via Thioester-to-Imide Acyl Transfer.

Cysteine thioesters are involved in a myriad of central biological transformations due to their unique reactivity. Despite their well-studied properties, we discovered an unexpected transamidation reaction of cysteine thioesters that leads to peptide backbone cleavage. -Acylcysteine-containing peptides were found to spontaneously fragment by cleavage of the amide bond in the -1 position to the acylated cysteine residue at pH 8-10.

Abraham Patchornik: The Contemporary Relevance of His Work for Chemistry and Biology.

Abraham Patchornik was born in 1926 in Ness Ziona, a town in Palestine founded by his great-grandfather Reuben Lehrer in 1883. He started to study chemistry as an undergraduate at the Hebrew University. However, this was interrupted by the war, and he completed his studies in various locations in West Jerusalem.

Decoding the Molecular Basis of the Specificity of an Anti-sTn Antibody.

The mucin -glycan sialyl Tn antigen (sTn, Neu5Acα2-6GalNAcα1--Ser/Thr) is an antigen associated with different types of cancers, often linked with a higher risk of metastasis and poor prognosis. Despite efforts to develop anti-sTn antibodies with high specificity for diagnostics and immunotherapy, challenges in eliciting high-affinity antibodies for glycan structures have limited their effectiveness, leading to low titers and short protection durations. Experimental structural insights into anti-sTn antibody specificity are lacking, hindering their optimization for cancer cell recognition.

Exploring the potential of some natural indoles as antiviral agents: quantum chemical analysis, inverse molecular docking, and affinity calculations.

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections represent critical global health challenges due to the high morbidity and mortality associated with co-infections. HIV, the causative agent of acquired immunodeficiency syndrome (AIDS), infects 4,000 people daily, potentially leading to 1.2 million new cases by 2025, while HCV chronically affects 58 million people, causing cirrhosis and hepatocellular carcinoma.

Spatio-temporal variability of mesozooplankton distribution along the Canary Current Large Marine Ecosystem: a regional perspective.

The Canary Current Large Marine Ecosystem (CCLME), extending from Cape Spartel in Morocco to Guinea-Bissau, supports high primary and fisheries productivity driven by permanent or seasonal upwelling activity. During the current study, mesozooplankton and hydrographic sampling were conducted across the CCLME in the spring/summer of 2017 and the autumn/winter of 2019. The total mesozooplankton abundance and dry weight were found to be higher in 2017, partly due to the summer reproduction cycle of diplostracans.

Sugar-sweetened beverages, relative grip strength, and psychological symptoms among rural adolescents in western China: a cross-sectional study.

Background: The increasing prevalence of psychological symptoms in adolescents has become an important problem faced by all countries in the world. The increased sugar-sweetened beverages (SSB) consumption and the decreased muscle strength had a serious negative impact on adolescent health. However, previous studies have mainly focused on adolescents in developed countries and fewer studies have been conducted in developing countries, especially in rural areas of western China.

Influenza vaccine effectiveness against influenza-associated hospitalizations in children, Hong Kong, November 2023 to June 2024.

We conducted a test negative study from November 2023 to June 2024, enrolling 4,367 children hospitalized with acute respiratory illness in Hong Kong. Among the children who tested negative for influenza virus and SARS-CoV-2, 56.8 % had received influenza vaccination.

How do tumours outside the gastrointestinal tract respond to dietary fibre supplementation?

Cancer remains one of the leading causes of death worldwide, despite advances in treatments such as surgery, chemotherapy, radiotherapy and immunotherapy. The role of the gut microbiota in human health and disease, particularly in relation to cancer incidence and treatment response, has gained increasing attention. Emerging evidence suggests that dietary fibre, including prebiotics, can modulate the gut microbiota and influence antitumour effects.

Amputees but not healthy subjects optimally integrate non-spatially matched visuo-tactile stimuli.

Our brain combines sensory inputs to create a univocal perception, enhanced when stimuli originate from the same location. Following amputation, distorted body representations may disrupt visuo-tactile integration at the amputated leg. We aim to unveil the principles guiding optimal and cognitive-efficient visuo-tactile integration at both intact and amputated legs.

Phosphoproteomics profiling of sorafenib-resistant hepatocellular carcinoma patient-derived xenografts reveals potential therapeutic strategies.

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer with poor prognosis. Sorafenib, a first-line treatment for advanced HCC, has shown limited clinical benefits due to the onset of drug resistance. Thus, it is imperative to comprehend the mechanisms underlying sorafenib resistance and explore strategies to overcome or delay it.

Application of nanomaterials in precision treatment of lung cancer.

Lung cancer remains one of the most prevalent and lethal malignancies worldwide, characterized by high mortality rates due to its aggressive nature, metastatic potential, and drug resistance. Despite advancements in conventional therapies, their efficacy is often limited by systemic toxicity, poor tumor specificity, and the emergence of resistance mechanisms. Nanomedicine has emerged as a promising approach to address these challenges, leveraging the unique physicochemical properties of nanomaterials to enhance drug delivery, reduce off-target effects, and enable combination therapies.

Decoding High Post-TAVR Gradients: Insights From 4 Clinical Scenarios.

Echocardiography is a well-established tool for evaluating bioprosthetic valve performance after transcatheter aortic valve replacement. The presence of higher-than-expected echocardiographic gradients is not an uncommon finding and can be related to different clinical settings. This case series proposes a practical and multiparametric approach to interpreting high residual gradients after transcatheter aortic valve replacement.

Transseptal Balloon-Assisted Translocation of Mitral Leaflet for Mitral Calcification: A First in Human Experience.

We present a first in human experience of transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification who was at high risk of left ventricular outflow tract obstruction.

P2X7R antagonism suppresses long-lasting brain hyperexcitability following traumatic brain injury in mice.

Post-traumatic epilepsy (PTE) is one of the most common life-quality reducing consequences of traumatic brain injury (TBI). However, to date there are no pharmacological approaches to predict or to prevent the development of PTE. The P2X7 receptor (P2X7R) is a cationic ATP-dependent membrane channel that is expressed throughout the brain.
