Advanced lipid peroxidation end-products (ALEs) accumulate with ageing and oxidative stress-related diseases. Despite their potential therapeutic value, there are no suitably protected ALE building blocks reported in the literature to enable their site-specific incorporation into synthetic peptides. The synthesis of an Fmoc-protected ALE building block, N-(3-methylpyridinium)lysine (MP-lysine) and its incorporation into collagen model peptides is reported.

Adhesion-driven vesicle translocation through membrane-covered pores.

Translocation across barriers and through constrictions is a mechanism that is often used in vivo for transporting material between compartments. A specific example is apicomplexan parasites invading host cells through the tight junction that acts as a pore, and a similar barrier crossing is involved in drug delivery using lipid vesicles penetrating intact skin. Here, we use triangulated membranes and energy minimization to study the translocation of vesicles through pores with fixed radii.

Menstrual pain affects women's quality of life and productivity, yet objective molecular markers for its severity have not been established owing to the variability in blood levels and chemical properties of potential markers such as plasma steroid hormones, lipid mediators, and hydrophilic metabolites. To address this, we conducted a metabolomics study using five analytical methods to identify biomarkers that differentiate menstrual pain severity. This study included 20 women, divided into mild (N = 12) and severe (N = 8) pain groups based on their numerical pain rating scale.

Background: Normothermic ex situ heart perfusion (ESHP) has emerged as a valid modality for advanced cardiac allograft preservation and conditioning prior to transplantation though myocardial function declines gradually during ESHP thus limiting its potential for expanding the donor pool. Recently, the utilization of dialysis has been shown to preserve myocardial and coronary vasomotor function. Herein, we sought to determine the changes in myocardial metabolism that could support this improvement.

Background: Arterial diseases like coronary artery disease, carotid stenosis, peripheral artery disease, and abdominal aortic aneurysm have high morbidity and mortality, making them key research areas. Their multifactorial nature complicates patient treatment and prevention. Biomarkers offer insights into the biochemical and molecular processes, while social factors also significantly impact patients' health and quality of life.

Steamed egg (SE), a traditional egg dish, exhibits steaming time-dependent textural properties. This study investigated the molecular mechanisms underlying SE gel formation and deterioration through quantitative proteomics combined with physicochemical characterization. Results showed optimal gel formation at 11 min steaming, while prolonged steaming (23 min) led to gel cracking and sensory deterioration.
