A study with transmission electron microscopy of mycoplasma-contaminated HeLa cells using five cell donors referred to as donors A, B, C, D and E, observations are herein presented. Experiments performed with cells from donors B, C and D, revealed the presence of Mycoplasma hyorhinis after PCR and sequencing experiments. Bacteria probably originated from a cytoplasm with compacted tiny granular particles replac...
OBJECTIVE: Exercise is a protective factor for cardiovascular morbidity and mortality, with unclear mechanisms. Changing the myocardial metabolism causes harmful consequences for heart function and exercise contributes to metabolic adjustment modulation. Peroxisome proliferator-activated receptors (PPARs) are also myocardium metabolism regulators capable of decreasing the inflammatory response. We hypothesized ...
PURPOSE: To investigate the relationship between the vascular diameter and the extent and histologic characteristics of atherosclerosis in the thoracic and abdominal aortas of patients who died of atherosclerotic disease. METHOD: We measured the vascular diameter and evaluated the percentage atrophy of the medial layer of the thoracic and abdominal aortas of 19 patients who died due to atherosclerotic disease. ...
Foram estudadas biópsias de ventrículo direito de 30 pacientes, 15 com doença crônica de Chagas e 15 com miocardiopatia congestiva idiopática. Analisou-se também cinco fragmentos miocárdicos obtidos de pacientes chagásicos com menos de duas horas de óbito. Os Autores tentaram estabelecer, por meio de técnica de imunofluorescência direta, a presença de imunoglobulina G, A, e M, fibrinogênio e C3. Somente uma das...
