Arterial pressure, age, gender, skin color, heart disease, body mass index, lipid profile, blood glucose

This study investigated risk factors associated with positive serological status for Trypanosoma cruzi antibodies in 26 rural communities including 905 households, 2,156 humans, and 333 dogs in Lara State, Venezuela. Serology was performed with ELISA and MABA. Data were obtained from entomological,

BACKGROUND American trypanosomiasis, known as Chagas' disease (CD) is a major cause of cardiomyopathy in South America. Irreversible damage to the heart can appear 10 to 20 years after chagasic infection. The frequency of cerebrovascular complications in chronic CD is unknown. OBJECTIVE To describe

BACKGROUND Two theories attempt to explain the changes observed in the nicotinic acetylcholine receptors (nAChRs) in chagasic cardiomyopathy. The neurogenic theory proposes that receptor changes are due to loss of intracardiac ganglia parasympathetic neurons. The immunogenic theory proposes that the

BACKGROUND The recent development of studies applied to ancient materials may be explained by the application of molecular biology techniques on the extracted ancient DNA mainly the polymerase chain reaction (PCR), the ultrasensitive DNA-amplification technique that hit the headlines in the late

BACKGROUND The present study aimed to evaluate apoptosis and cell proliferation alterations in esophageal benign lesions in comparison to esophageal carcinomas. METHODS Immunohistochemistry was performed for caspase-3 protein (CPP32) and Ki-67 antigen expression in the esophageal mucosa from

BACKGROUND Heart disease progression occurs in 30% of patients with chronic Trypanosoma cruzi infection. Supplementation with selenium (Se) in animal model of T. cruzi infection produced promising results. There is evidence that patients with Chagas heart disease have lower Se levels than healthy

Heart failure (HF) data in Latin America (LA) were reviewed to guide health service planning in the prevention and treatment of HF. The HF epidemiology and the adequacy of relevant health service provision related to HF in LA are not well delineated. A systematic search of the electronic databases
