Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Acne vulgaris (AV) is a common chronic inflammatory skin disorder that commonly lasts from adolescence to adulthood and has serious social and psychological consequences. Current treatments typically use antibacterial drugs, which contributes to the rise in antibacterial drug resistance. Spironolactone, a potassium-sparing diuretic with anti-androgen effects, has been used off-label to treat acne by lowering sebum production.

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune inflammatory diseases, with a progressive etiology that results in serious complications and a higher chance of early death. Visfatin, an adipokine, is correlated with disease pathologic features and becomes a key biomarker and therapeutic target for RA. This study aimed to evaluate the anti-arthritic activity of metformin (an antidiabetic drug with anti-inflammatory activities) and methotrexate (the first choice for disease-modifying antirheumatic drugs in RA, with diverse adverse effects) in complete Freund's adjuvant (CFA)-induced arthritis in female rats.

Oxidative stress plays a major role in the secondary injury of the spinal cord tissue due to the high lipid content of nervous tissue. In the present study, coaxial nanofibers were loaded with the natural antioxidant pyrroloquinoline quinone (PQQ) and used as an implantable drug-delivery system and a scaffold post-SCI. The obtained data show that the concentration of NO and the activity of inducible nitric oxide synthase (iNOS) were significantly ( < 0.

This study was conducted to investigate whether the addition of photobiomodulation therapy (PBMT) to pelvic floor exercises (PFEs) is more effective in treating postpartum coccydynia compared with either modality alone. Postpartum coccydynia is a widespread condition that significantly affects the quality of life. Inflammation as a response to childbirth trauma and weakening of the muscles and ligaments attached to the coccyx are presumed causes of postpartum coccydynia.

This study presents a comprehensive workflow to detect low seismic amplitude gas fields in hydrocarbon exploration projects, focusing on the West Delta Deep Marine (WDDM) concession, offshore Egypt. The workflow integrates seismic spectral decomposition and machine learning algorithms to identify subtle anomalies, including low seismic amplitude gas sand and background amplitude water sand. Spectral decomposition helps delineate the fairway boundaries and structural features, while Amplitude Versus Offset (AVO) analysis is used to validate gas sand anomalies.

Background And Study Aims: Hepatitis C virus (HCV) infection is a significant problem in Egypt, as it is associated with various hematological disorders, both benign and malignant. In Egypt, direct-acting antivirals (DAAs) serve as the principal therapy for HCV to achieve a sustained virological response (SVR). This study investigated the effects of sofosbuvir (SOF) and daclatasvir (DCV) on HCV patients with benign blood index abnormalities and examined the correlation between these abnormalities and SVR.
