Abstract Objective: To describe the chest computed tomography (CT) findings in immunocompetent children under 36 months of age with pulmonary tuberculosis. Materials and Methods: This was a descriptive case series conducted in the city of Rio de Janeiro, Brazil, between January 2004 and July 2013, invo...
Aim: To determine indicators of oxidative stress in long-lived individuals. Methods: 120 subjects were studied and two groups were formed: 50 individuals older than 85 years of nuclear families and 70 adults under 60 years old taken as a control group, all belonging to the municipality of Santa Clara....
Background: Living above 2,500 meters in hypobaric conditions induces pulmonary arterial hypertension of the neonate (PAHN), a syndrome whose main features are: pathological remodeling of the pulmonary vessels, abnormal vascular reactivity and increased oxidative stress. Melatonin could have pulmonary an...
El granuloma anular (GA) es una dermatosis inflamatoria granulomatosa, generalmente asintomática, con distintas formas de presentación clínica, que puede distribuirse de forma localizada o generalizada. su etiología es incierta pero se la ha vinculado a factores desencadenantes como traumatismos, fá...
Resumen Las especies reactivas del oxígeno (ROS) son producidas como una consecuencia del metabolismo aeróbico fisiológico normal. La cadena de transporte de electrones de la mitocondria, los peroxisomas, la NADPH oxidasa, la óxido nítrico sintetasa desacoplada y el sistema del citocromo P450 son la...
Copaifera multijuga, commonly known as copaiba, is popularly used in the form of tea for various conditions due to the presence of antioxidant substances in its composition, which protect cells against damage caused by free radicals. Its oleoresin is also used as an anti-inflammatory and antitumoral agen...
ABSTRACT Purpose: We aimed to compare the aqueous humor total oxidant status, total antioxidant capacity, and levels of interleukin-6 and vascular endothelial growth factor between patients with diabetic retinopathy and controls and to correlate these levels with the DR status. Methods: Patients who un...
