Trypanosoma cruzi prevalence rates of human, dog and cat populations from 47 households of 3 rural localities of the phytogeographical Chaquena area of Argentina were determined both by serological and xenodiagnostic procedures. Human prevalence rates were uniform and ranged from 49.6 to 58.7%. Overall pre­ valence rate in dogs (75.0%) was significantly higher than in humans (51 .0%) . The over...

This year marks the 20th anniversary of the publica­ tion showing the blood pressure–lowering effects of the Dietary Approaches to Stop Hypertension (DASH) diet.1 The DASH diet is considered an important ad­ vance in nutritional science. It emphasizes foods rich in protein, fiber, potassium, magnesium, and calcium, such as fruits and vegetables, beans, nuts, whole grains, and low-fat dairy. It ...

Clinical Decision Support Systems (CDSS) provide clinicians, staff, patients, and other indi‐ viduals with knowledge and person-specific information, intelligently filtered and present‐ ed at appropriate times, to enhance health and health care [1]. Medical errors have already become the universal matter of international society. In 1999, IOM (American Institute of Medicine) published a report ...

Satellite transmitters were attached to green turtles Chelonia mydas while they were nesting on Ascension Island in the South Atlantic (7"57'S, 14"22'W) and individuals were subsequently monitored during the inter-nesting period and the post-nesting migration to Brazil. During the inter-nesting period, data from the transmitters suggested that turtles generally stayed within 5 km of the nesting...

The objective of this study was to perform a study of fragile X syndrome (FXS) in São Luís, Maranhão, in males residing in five specialized institutions. Two hundred thirty-eight males with intel-lectual disability of unknown etiology participated in this study. Blood samples were processed and stored until DNA extraction. Screening for FMR1 gene mutations was performed using non-isotopic polym...

In humans and rabbits, differences in the rate of N-acetylation of aromatic amines are under polymorphic genetic control. Indi viduals are classified as either rapid or slow acetylators. In the current study, the relationship between acetylator phenotype and susceptibility to the genotoxicities of benzidine, 4-aminobiphenyl, 4,4'-methylenebis-2-chloroaniline, and 2-naphthylamine was investigate...

Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...
