A method based on scanning Kelvin probe microscopy is developed to probe the effects of minority carriers on the switching characteristics of organic field-effect transistors. The mobility of the minority carriers is extracted and the role they play in screening of the gate potential in the OFF state and in recombination of trapped majority carriers trapped after an ON state is understood.

Background: Around 7% of the global population has congenital hemoglobin disorders, with over 300,000 new cases of α-thalassemia annually. Diagnosis is costly and inaccurate in low-income regions, often relying on complete blood count (CBC) tests. This study employs machine learning (ML) to classify α-thalassemia traits based on gender and CBC, exploring the effects of grouping silent- and non-carriers.

One of the primary challenges in commercializing perovskite solar cells (PSCs) is achieving both high power conversion efficiency (PCE) and sufficient stability. We integrate wafer-scale continuous monolayer MoS buffers at the top and bottom of a perovskite layer through a transfer process. These films physically block ion migration of perovskite into carrier transport layers and chemically stabilize the formamidinium lead iodide phase through strong coordination interaction.

Background And Purpose: Symptomatic internal carotid artery stenosis (sCAS) is an essential cause of transient ischaemic attack (TIA) or minor stroke. We aimed to evaluate whether the superiority of aspirin-ticagrelor over aspirin-clopidogrel varies between patients with sCAS or not.
Methods: This was a post-hoc analysis of the High-Risk Patients with Acute Nondisabling Cerebrovascular Events-II (CHANCE-2) trial, all of which were loss-of-function alleles carriers.

Background: The monocarboxylate transporter 1 (MCT1) plays a crucial role in regulating lactate and pyruvate transport across cell membranes, which is essential for energy metabolism during exercise. The A1470T (rs1049434) polymorphism has been suggested to influence lactate transport, with the T (major) allele associated with greater transport efficiency. This study aimed to investigate the effect of the polymorphism on lactate and potassium (K) concentrations in response to resistance exercise (RE) following caffeine (CAF) ingestion.

Urticaria is a debilitating skin condition affecting up to 20% of the global population, characterized by erythematous, maculopapular lesions and significant quality of life impairment. This study focused on the role of interleukin 33 (IL-33) and its polymorphisms, particularly SNP , in chronic spontaneous urticaria (CSU). Using demographic, clinical, and laboratory data from CSU patients and controls, we estimated allele and genotype frequencies, Hardy-Weinberg equilibrium condition, and serum IL-33 levels, using unconditional binomial logistic regression for association analysis.
