It is almost impossible for a majority of the students to create the same environment at home that they have at school to prepare and review. To solve this problem, the authors have developed and tested a Live CD to distribute to students so they can do their work away from the school. Moreover, we developed some application software for children because of availably for not only the university...

The present work aimed at better understanding metal and metalloid bioaccumulation in the edible Pacific blue shrimp Litopenaeus stylirostris, using both laboratory and field approaches. In the laboratory, the bioaccumulation kinetics of Ag, Cd, Co, Cr, and Zn have been investigated in shrimp exposed via seawater and food, using the corresponding gamma-emitting radiotracers ((110 m)Ag, (109)Cd,...

We report on a case of a 65-year-old (CD) woman who sustained an atraumatic neck fracture. A combination of Parkinson's disease with motor fluctuations, chronic cervical dystonia and osteoporosis provided the basis for this interesting diagnosis. Mrs CD had progressed to complex phase idiopathic Parkinson's disease within 13 years of diagnosis. During this time she remained independent, only us...

AIMS To evaluate whether the a-wave of the dark adapted flash electroretinogram (ERG) is affected by glaucomatous damage. METHODS ERGs were recorded in 20 patients (age 33-65 years) with advanced glaucomas (primary and secondary open angle and low tension glaucomas) and 20 normals using a ganzfeld stimulus. After 30 minutes of dark adaptation and pupil dilatation to at least 7.5 mm in diamete...

BACKGROUND In this longitudinal cohort study we evaluated the congenital transmission of Chagas disease (CD) in a nonendemic area. The aim of this work was to analyze the predictive value of a Trypanosoma cruzi-positive polymerase chain reaction (PCR) result in pregnant women for the diagnosis of vertical transmission and to evaluate the use of PCR as a tool for early detection of infection. ...
