Cutaneous innate lymphoid populations drive IL-17A-mediated immunity in Nannizzia gypsea dermatophytosis.

Fungal skin infections significantly contribute to the global human disease burden, yet our understanding of cutaneous immunity against dermatophytes remains limited. Previously, we developed a model of epicutaneous infection with Microsporum canis in C57BL/6 mice, which highlighted the critical role of IL-17RA signaling in anti-dermatophyte defenses. Here, we expanded our investigation to the human pathogen Nannizzia gypsea and demonstrated that skin γδTCRint and CD8/CD4 double-negative βTCR+ T cells are the principal producers of IL-17A during dermatophytosis.

Highly sensitive ultra-high-performance liquid chromatography coupled with tandem mass spectrometry method for the multiplex analysis of levosimendan and its metabolites OR-1855 and OR-1896 in human plasma.

Levosimendan is a positive inotrope and vasodilator used in patients with acute and chronic decompensated heart failure. It is metabolized into OR-1855 (inactive metabolite), which is further acetylated into OR-1896 (active metabolite having a prolonged half-life, hence a sustained effect). Levosimendan represents a valuable alternative to traditional inotropes with broad clinical applications in critically ill patients with cardiogenic shock, advanced heart failure and post-cardiac surgery.

Significant differences in knee kinematics of healthy subjects with high and low anterior tibial laxity.

Background: Anterior tibial laxity is considered to be a risk factor for knee injuries, including anterior cruciate ligament ruptures. The anterior cruciate ligament reconstruction also aims to restore anterior tibial laxity. While anterior tibial laxity is considered to be linked to dynamic knee stability, the mechanisms connecting anterior tibial laxity to these stability issues are not fully understood.

Pharmacokinetic Interaction between Imatinib and Tacrolimus in Rats.

Objective: Tacrolimus, a calcineurin inhibitor (CNI), is the first-line treatment for chronic myeloid leukemia (CML) and advanced gastrointestinal stromal tumors (GIST). Imatinib and tacrolimus are both substrates of the hepatic enzymes CYP3A4/5 and efflux transporter P-gp, so drug-drug interactions may occur during their co-administration treatment. Therefore, this study aimed to evaluate the pharmacokinetic interaction between imatinib and tacrolimus in rats.

Machine-learning based prediction of appendicitis for patients presenting with acute abdominal pain at the emergency department.

Background: Acute abdominal pain (AAP) constitutes 5-10% of all emergency department (ED) visits, with appendicitis being a prevalent AAP etiology often necessitating surgical intervention. The variability in AAP symptoms and causes, combined with the challenge of identifying appendicitis, complicate timely intervention. To estimate the risk of appendicitis, scoring systems such as the Alvarado score have been developed.

Alterations of Oscillatory Activity and Cognitive Function After Aneurysmal Subarachnoid Hemorrhage.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) can lead to cognitive impairment, but underlying neural mechanisms remain to be elucidated.

Materials And Methods: To predict long-term cognitive impairment after aSAH, resting electroencephalography (EEG) was measured in 112 patients hospitalized with a diagnosis of aSAH (n = 66) or unruptured intracranial aneurysms (UIA; controls) (n = 46). A neuropsychological battery was administered 8 to 24 months after discharge.

Glucocorticoid-Dependent Retinal Degeneration and Vision Impairment in Mice Susceptible to Prenatal Stress-Induced Behavioral Abnormalities.

Chronic exposure to prenatal stress can impair neurogenesis and lead to irreversible cognitive and neuropsychiatric abnormalities in offspring. The retina is part of the nervous system; however, the impacts of prenatal stress on retinal neurogenesis and visual function remain unclear. This study examined how elevated prenatal glucocorticoid levels differentially affect retinal development in the offspring of pregnant mice exposed to chronic unpredictable mild stress (CUMS).

Triglyceride-glucose index mediates the association between residual cholesterol and stroke among middle-aged and older adults in China: a prospective, nationwide, population-based study.

Background: Both triglyceride-glucose (TyG) index and residual cholesterol (RC) are predictors of stroke; however, to what extent the RC is associated with stroke through TyG index is unclear. This study examined whether the TyG index mediates the association of RC with incident stroke and the extent of interaction or joint relations of RC and TyG index with stroke in middle-aged and older Chinese adults.

Methods: This is an ongoing prospective cohort study initiated in 2011 that included 10,569 middle-aged and older Chinese adults without stroke at baseline.

Purpose: This study aimed to investigate the relationship between intraoperative sleep spindle activity and postoperative sleep disturbance (PSD) in elderly orthopedic surgery patients.

Patients And Methods: In this prospective observational cohort study, we collected intraoperative electroencephalography (EEG) data from 212 elderly patients undergoing orthopedic surgery from May 2023 to December 2023. We used the Athens Insomnia Scale to assess sleep quality on postoperative day (POD) 1 and POD 3 and analyzed the correlation between intraoperative sleep spindle activity and PSD through logistic regression.

Electroencephalogram criticality in cognitive impairment: a monitoring biomarker?

Unlabelled: Critical states present scale-free dynamics, optimizing neuronal complexity and serving as a potential biomarker in cognitively impaired patients. We explored electroencephalogram (EEG) criticality in amnesic Mild Cognitive Impairment patients with clinical improvement in working memory, verbal memory, verbal fluency and overall executive functions after the completion of a 6-month prospective memory training. We compared "before" and "after" stationary resting-state EEG records of right-handed MCI patients (n = 17; 11 females), using the method of critical fluctuations and Haar wavelet analysis.

Cynaropicrin Increases [Ca] and Ciliary Beat Frequency in Human Airway Epithelial Cells by Inhibiting SERCA.

Mucociliary clearance (MCC) is a host defense mechanism of the respiratory system. Beating cilia plays a crucial role in the MCC process and ciliary beat frequency (CBF) is activated by several factors including elevations of the intracellular cAMP concentration ([cAMP]), intracellular Ca concentration ([Ca]), and intracellular pH (pH). In this study, we investigated whether an artichoke-extracted component cynaropicrin could be a beneficial compound for improving MCC.
