Study of hepatocellular function in the murine model following hepatic artery s...

PURPOSE: To investigate the impact of selective hepatic artery clamping (SHAC) in hepatocellular function. METHODS: Three groups of Wistar male rats were subjected to SHAC ischemia period of 60min: Group A continuous SHAC were subjected to SHAC ischemia period of 60min, Group B intermittent SHAC of 30min with 5min of reperfusion and Group C intermittent SHAC of 15min with 5min of reperfusion. Animals without SH...

The influence of selective clamping of the elements of hepatic pedicle in the hepatocellular function and viability were evaluated in our department. AIM: Study the effect of selective clamping of the portal vein (CPV) in hepatocellular function in an animal model with normal liver. METHOD: Three groups of Wistar rats (males, 2 months) were subjected a CPV for 60 min: group A (n=21) submitted to a continuous ...

Halogen atom effect on photophysical and photodynamic characteristics of deriva...

Brominated and iodinated derivatives of 5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin were synthesised directly from the corresponding aldehydes. Photophysical and photochemical properties, singlet oxygen formation quantum yields, photobleaching and log P were measured. Cellular uptake measurements and cytotoxicity assays on WiDr and A375 tumour cell lines were performed. 5,10,15,20-Tetrakis(2-bromo-5-hydroxyph...

Pregnancy and its role in breast cancer

Early full-term pregnancy is the only recognized factor able to prevent breast cancer. There are several hypotheses to explain the mechanisms of this protection, namely an altered hormonal milieu, a differentiation process or a switch in stem cell properties. To explore them, authors have been using animal models, mainly in rodents. Hormonal administration with estrogen and progesterone was the most widely used...

Excesso de peso e obesidade: prevenção na escola

Introdução: A obesidade é uma doença crónica e a sua prevalência tem vindo a aumentar na infância e na adolescência de forma alarmante. A escola pode desempenhar um papel importante na prevenção desta patologia, integrando a obesidade nos programas curriculares e desenvolvendo acções complementares que visem valorizar hábitos de vida saudáveis. Objectivos: Determinar a incidência de excesso de peso e de obesida...
