High-density lipoprotein (HDL) and small dense low-density lipoprotein (sdLDL) represent two critical yet contrasting components in lipid metabolism and cardiovascular risk modulation. While HDL has traditionally been viewed as cardioprotective due to its role in reverse cholesterol transport and anti-inflammatory effects, emerging evidence emphasizes that HDL functionality-rather than concentration alone-is pivotal in atheroprotection. Conversely, sdLDL particles are increasingly recognized as highly atherogenic due to their enhanced arterial penetration, oxidative susceptibility, and prolong

BACKGROUND: The Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) and Longitudinal Evaluation of Amyloid Risk and Neurodegeneration (LEARN) studies were conducted between 2014 and 2023, with enrollment completed in 2017 and final study results reported in 2023. The study screening process involved the collection of initial clinical, cognitive, neuroimaging, and genetic measures to determine eligibility. Once randomized, enrolled participants were assessed every four weeks over a 4.5-year follow-up period during which longitudinal clinical, cognitive, and neuroimaging measures wer

Abstract Mammalian preimplantation embryo development is a complex sequence of events. This period of development is sensitive to oxygen (O 2 ) levels that can affect various cellular processes. We compared the influence of O 2 tension by culturing embryos either in normoxic (20% O 2 ) or physiological hypoxic (6% O 2 ) conditions, or sequential low O 2 concentration starting with 6% O 2 until 16-cell stage and then switching to ultrahypoxic conditions (2% O 2 ). Due to ethical concerns, we used bovine as an animal model with a good similarity of embryogenesis to human. We found that the cleav

Chronic obstructive pulmonary disease (COPD) remains a leading cause of morbidity and mortality around the globe. Its main characteristics are persistent respiratory symptoms and progressive airflow limitation, both of which are driven by chronic inflammation. Despite the use of maximum bronchodilation and in selected patients inhaled corticosteroids (ICS), current therapies neither halt disease progression nor prevent exacerbations and loss of lung function. Recent research has focused on developing novel anti-inflammatory agents targeting specific pathways implicated in COPD pathogenesis, ai

Muller's ratchet1 predicts that when mutation rates are high and a significant proportion of mutations are deleterious, a kind of irreversible ratchet mechanism will gradually decrease the mean fitness of small populations of asexual organisms.2 In cell culture, serial passage of genetically bottlenecked vesicular stomatitis virus, which grew quite rapidly on HeLa cells, severely reduced in fitness and virulence within 20 passages in a novel BHK host cell.2 Genetic bottlenecks are likely important in intraspecies viral transmission.3 RNA-based viruses are particularly prone to repeated bottlen

The accurate and efficient calculation of protein-protein binding affinities is an essential component in antibody and antigen design and optimization, and in computer modeling of antibody affinity maturation. Such calculations remain challenging despite advances in computer hardware and algorithms, primarily because proteins are flexible molecules, and thus, require explicit or implicit incorporation of multiple conformational states into the computational procedure. The astronomical size of the amino acid sequence space further compounds the challenge by requiring predictions to be computed
