Two cases of hypercalcemia associated with transitional cell carcinoma and negative bone scan are described. In both cases hypercalcemia appeared while there was evidence of tumor spread. Although hypercalcemia was controlled, both patients died shortly thereafter. Hypercalcemia rarely occurs in transitional cell carcinoma and its appearance may suggest spreading of the tumor and poor prognosis.

Obesity, which is becoming one of the major health hazards in developed and developing societies, results from a long-term positive energy balance. Body-weight regulation and stability depend on an axis with three interrelated components: food intake, energy expenditure and adipogenesis, although there are still many unknown features concerning fuel homeostasis and energy balance. Biochemical p...

High reproductive efficiency in the dairy cow requires a disease-free transition period, high submission rates to AI and high pregnancy rates per service. A key risk factor that causes increased incidence of metabolic disease is low negative energy balance (NEB) in the periparturient and early postpartum periods. Low NEB decreases LH pulse frequency, growth rate and diameter of dominant follicl...

In tropical countries such as Thailand, dairy cows particularly raised in small-holder farms are confronted by a problem of improper nutritional management and its consequences, which may lead to impair their production, health and fertility. This review attempted to summarize some nutritional factors influencing reproductive performance especially during postparturient period. The small-scale ...

Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...
