Introduction The development of biomaterials for biomedical applications always requires extensive biological testing to demonstrate the safety of both the material and its degradation components. K-carrageenan is a naturally occurring polysaccharide which forms a hydrogel with potassium ions and the temperature-induced gelation enables its application as an in vitro cell-carrier or as an in vivo injectable sys...
Hematological and biochemical parameters, including plasma electrolytes and thyroid hormones, were determined in 73 clinically healthy Churra-da-Terra-Quente ewes, a typical breed from the northeast of Portugal. The hemogram values were: erythrocytes 9.8±1.5×10(12)/L; haemoglobin 118.1±19.1g/L; haematocrit 40.8±5.9%; leukocytes 5.7±1.8×10(9)/L; and platelets 544.3±177.2×10(9)/L. The thrombin time was 17.3±1.7 s...

Pacientes com oligozoospermia apresentam uma redução na qualidade do sêmen, independente da etiologia do distúrbio. OBJETIVO. Investigar o papel da varicocele na redução da qualidade do sêmen, em homens oligozoospérmicos. MÉTODOS. Foram estudados dez pacientes portadores de varicocele clínica esquerda (PCV) e 21 pacientes não-portadores desta entidade (PSV), atendidos em um laboratório privado, em Petrópolis, R...
