Objective: The aim of this study was to evaluate the relation between blood gamma-glutamyltransferase (GGT) levels and coronary collateral circulation in patients with chronic total occlusion (CTO).
Methods: Two hundred twenty-two patients with chronic stable coronary artery disease (CAD) and CTO were included in this cross-sectional, observational study. Coronary collaterals were graded from 0 to 3 according to the Rentrop method. Patients with grade 0-1 collateral development were regarded as poor collateral group (n=66) while patients with grade 2-3 collateral development were regarded as good collateral group (n=156). Statistical analysis was performed using independent samples t, Mann-Whitney U and Chi-square tests, logistic regression and receiver operator curve analysis.
Results: The poor coronary collateral group had significantly higher levels of serum GGT compared to the good collateral group (p<0.001). Multiple logistic regression analysis showed that GGT levels were independent predictors of poor collateral circulation (OR-0.946, 95% CI=0.918-0.9719, p<0.001). The result of ROC curve analysis for GGT was as following: area under the ROC curve (AUC)=0.732, 95% CI: 0.622-0.841, p<0.001.
Conclusion: Higher GGT levels are associated with poor coronary collateral circulation in patients with CTO. GGT may be used to predict the grade of coronary collateral circulation in CTO patients with chronic stable CAD.

Chronic ischemia in moyamoya disease (MMD) impaired white matter microstructure and neural functional network. However, the coupling between cerebral blood flow (CBF) and functional connectivity and the association between structural and functional network are largely unknown. 38 MMD patients and 20 sex/age-matched healthy controls (HC) were included for T1-weighted imaging, arterial spin labeling imaging, resting-state functional MRI and diffusion tensor imaging.

Conflict-affected regions face severe reproductive health challenges that disproportionately impact adolescent girls and young women (AGYW) and children, who are especially vulnerable due to the breakdown of healthcare systems and limited access to essential services. AGYW are at heightened risk due to restricted access to family planning, prenatal care, and emergency obstetric services, while children face malnutrition, disease outbreaks, and developmental delays. These challenges have profound long-term consequences for both their physical and psychological well-being.

Background: Major aortopulmonary collateral arteries (MAPCAs) are rare remnants of pulmonary circulation embryological development usually associated with complex congenital anomalies of the right ventricular outflow tract and pulmonary arteries. Effective management requires surgical unifocalization of MAPCAs and native pulmonary arteries (NPAs). Traditional imaging may lack the spatial clarity needed for precise surgical planning.

: Impacted third molar extraction with a scalpel and rotary instruments is one of the most traumatic surgeries in dentistry. Therefore, it is necessary to discover less traumatic methods and instruments to reduce the risk of postoperative complications. : This study is reported in accordance with the CONSORT guidelines.

Multidrug resistance (MDR) is a major challenge in cancer research. Collateral sensitizers, compounds that exploit the enhanced defense mechanisms of MDR cells as weaknesses, are a proposed strategy to overcome MDR. Our previous work reported the synthesis of two novel Isoquinolinequinone (IQQ) N-oxides that induce collateral sensitivity in MDR ABCB1-overexpressing non-small cell lung cancer (NSCLC) and colorectal cancer cells.
