OBJECTIVE: To present the experiences of consumers with traditional hearing aids (T-HAs) and digital signal processing hearing aids (DSP-HAs) during the period 1999-2001, based on data obtained from a…
Improvements of ultrasound technology with knew equipments allowed enormous advances in all fields of medicine during the last years. Several conditions concerning technical equipment and training of …
The dynamic behavior of the ossicular chain is very complex and is frequency-dependent. To date, this has still not been fully investigated or understood. There remains a lack of measurement procedure…
We describe a new species of the genus Apostolepis found near S?o Salvador Hydroelectric Power Plant, municipality of S?o Salvador do Tocantins, in the central Cerrado ecoregion. The new species is di…
Physiological adaptations to various types of prolonged and intensive physical activity, as seen in elite athletes from different sports, include changes in blood pressure (BP) response to acute exerc…
Telemedicine offers the potential to alleviate the severe shortage of medical specialists in developing countries. However lack of equipment and poor network connections usually rule out video-confere…
A novel method for damage-free, artifact-free stimulation of neural tissue using pulsed, low-energy infrared laser light is presented. Optical stimulation elicits compound nerve and muscle potentials …
Reaching mothers and their newborn infants around the time of birth with adequate health services has long been a difficult problem in developing countries. In parallel, similar problems have arisen i…
OBJECTIVES: The primary objective of this study was to examine associations between depression and several measures of health behaviour change across 8 cycles of a population-based, cross-sectional su…
Ten formalin-fixed atherosclerotic carotid plaques removed by endarterectomy were molded into rectangular agar blocks containing fiducial markers on the top surface. Plaque and fiducial markers were i…
We used computer simulation method to address the question of power in an initial collaborative sample of 51 bipolar affective disorder pedigrees. Simulations were performed for all possible combinati…
Upon presentation of a calorically dense diet, rats display hyperphagia driven by increased meal size. The increased meal size and hyperphagia are most robust across the first several days of diet exp…
The use of Lactobacillus rhamnosus GR-1 and micronutrients has been associated with a preserved immune function among people living with HIV. However, use of these products in the developing world rem…
We report results of measurements of isotopic ratios obtained with atom probe tomography on U3O8 reference materials certified for their isotopic abundances of uranium. The results show good agreement…
BACKGROUND: Individuals with attention-deficit/hyperactivity disorder (ADHD) are reported to manifest visual problems (including ophthalmological and color perception, particularly for blue-yellow sti…
Here, we describe an in vitro culture assay to study coronary angiogenesis. Coronary vessels feed the heart muscle and are of clinical importance. Defects in these vessels represent severe health risk…
Retrograde drilling of osteochondral lesions has obtained acceptable results in the initial stage. Intraoperatively not all lesions are accessible with the arthroscopic technique, despite being readil…
BACKGROUND: Labyrinthine Aplasia, Microtia and Microdontia (LAMM) syndrome is characterized by the complete absence of inner ear structures (Michel aplasia), microtia and microdontia. Hypophosphatemic…
Membrane stability is of central concern in many biology and biotechnology processes. It has been suggested that intramembrane electrostatic interactions play a key role in membrane stability. However…
Even though parasitic flatworms are one of the most species-rich groups of hermaphroditic organisms, we know virtually nothing of their mating systems (selfing or kin-mating rates) in nature. Hence, w…
