A robust HIV-1 viral load detection assay optimized for Indian sub type C specific strains and resource limiting setting

Biol. Res; 47 (), 2014
BACKGROUND: Human Immunodeficiency Virus Type 1 (HIV-1) viral load testing at regular intervals is an integral component of disease management in Acquired Immunodeficiency Syndrome (AIDS) patients. The need in countries like India is therefore an assay that is not only economical but efficient and highly...

Effects of crowding and sex on fecal cortisol levels of captive forest musk deer

Biol. Res; 47 (), 2014
BACKGROUND: Restricted space and close contact with conspecifics in captivity may be stressful for musk deer, as they are highly territorial and solitary in the wild. So we tested the effects of crowding on stress of forest musk deer (Moschus berezovskii) in heterosexual groups, using fecal cortisol anal...

Expression of TRF2 and its prognostic relevance in advanced stage cervical cancer patients

Biol. Res; 47 (), 2014
BACKGROUND: Telomeres are protective caps consisted of specific tandem repeats (5'-TTAGGG-3'). Shortening of telomeres at each cell division is known as "mitotic clock" of the cells, which renders telomeres as important regulators of lifespan. TRF2 is one of the critical members of shelterin complex, whi...

Activation of group II metabotropic glutamate receptors blocks zinc release from hippocampal mossy fibers

Biol. Res; 47 (), 2014
BACKGROUND: The hippocampal CA3 area contains large amounts of vesicular zinc in the mossy fiber terminals which is released during synaptic activity, depending on presynaptic calcium. Another characteristic of these synapses is the presynaptic localization of high concentrations of group II metabotropic...

Apoptosis in HEp-2 cells infected with Ureaplasma diversum

Biol. Res; 47 (), 2014
BACKGROUND: Bacterial pathogens have many strategies for infecting and persisting in host cells. Adhesion, invasion and intracellular life are important features in the biology of mollicutes. The intracellular location ofUreaplasma diversum may trigger disturbances in the host cell. This includes activat...

Genetic polymorphisms and asthma: findings from a case - control study in the Madeira island population

Biol. Res; 47 (), 2014
BACKGROUND: Asthma is a complex disease influenced by multiple genetic and environmental factors. While Madeira has the highest prevalence of asthma in Portugal (14.6%), the effect of both genetic and environmental factors in this population has never been assessed. We categorized 98 asthma patients acco...

Evaluación objetiva de competencias técnicas en cirugía
[Evaluation of technical skills in surgical training].

INTRODUCTION: technical skills acquisition is considered to be of paramount importance in surgical training. Yet, formal assessment of technical skills is the weakest and less developed area. Currently available resources to evaluate technical skills are largely subjective, and lack of validity and relia...

The influence of tooth brushing supervision on the dental plaque index and toothbrush wear in preschool children

Objective: To evaluate the effectiveness of tooth brushing supervision in one or more sessions on dental plaque removal and toothbrush wear. Material and Method: 3- to 5-year-old children received new toothbrushes and attended a puppet theater about oral health. Forty-nine children were randomly selected...

Objetivo: Avaliar hábitos de higiene bucal, hábitos alimentares e pH salivar em pacientes com ausência e presença de lesões cervicais não cariosas. Método: Por meio de um estudo transversal, foram avaliados 88 pacientes, de ambos os sexos, feminino (63,6%) e masculino (36,4%), entre 18 e 71 anos, ...

Experiência de cárie e osmolaridade salivar em crianças com paralisia cerebral

Introdução: Estudos têm demonstrado que quanto maior a severidade do dano neurológico em crianças com paralisia cerebral (PC), maior é o risco de doenças orais. Objetivo: Correlacionar a experiência de cárie com a osmolaridade salivar em crianças com PC. Material e Método: Participaram do estu...
