The newly formed corpus luteum (CL) rapidly develops after ovulation and has the features of active vascularisation and mitosis of steroidogenic cells. These stage-specific mechanisms also may contribute to gain the function of prostaglandin F2 alpha (PGF2 alpha)-resistant CL at this stage. Recent studies suggest that the vasoactive peptide angiotensin II(More)
Leptin suppresses food intake and increases energy expenditure in the hypothalamus. Rats consume most of their daily food intake during the dark phase of the diurnal cycle. Lactating rats have increased food intake, but the involvement of leptin in the regulation of food intake in this physiological condition is not well understood. The present experiment(More)
The distribution and organization of odontoblast processes in young human dentin was examined with a scanning electron microscope. By applying the HCl-collagenase method, the extracellular matrix of dentin was almost completely removed, thereby exposing the odontoblast processes and their branches to direct observation. The odontoblast processes are located(More)
Brown adipose tissue (BAT) plays an important role in thermoregulation in species living in cold environments, given heat can be generated from its chemical energy reserves. Here we investigate the existence of BAT in blubber in four species of delphinoid cetacean, the Pacific white-sided and bottlenose dolphins, Lagenorhynchus obliquidens and Tursiops(More)
