Long-chain N-vanillyl-acylamides from Capsicum oleoresin.

N-Vanillyl-acylamides (NVAs) naturally occur as capsaicinoids in Capsicum plants. NVAs with a longer chain acyl moiety (LCNVAs) have been developed as attractive tools for medicinal usage because of their capsaicin-like bioactive and physiological properties, without harmful irritancy. In this study, we isolated four LCNVAs from Capsicum oleoresin.

Oleuropein, a phenolic compound in extra virgin olive oil, increases uncoupling protein 1 content in brown adipose tissue and enhances noradrenaline and adrenaline secretions in rats.

The effects of oleuropein, a phenolic compound in extra virgin olive oil (EV-olive oil), on triglyceride metabolism were investigated by measuring the degree of thermogenesis in interscapular brown adipose tissue (IBAT), and noradrenaline and adrenaline secretions in rats. In Experiment 1, rats were given a high-fat diet (control diet) with the oleuropein supplementation of 1, 2 or 4 mg/kg of diet (0.1, 0.

Patient dose estimation for multi-detector-row CT examinations.

The spread of Multi-detector-row computed tomography (MDCT) has been remarkable. Here, various organ and tissue doses were evaluated with six types of MDCT scanners in common use in Japan; using thermoluminescence dosimeters and anthropomorphic phantoms under condition of routine clinical examinations of the chest in adult and child, of the head in child and of the abdomen-pelvis in adult. Estimated lung doses and averaged effective dose in chest examinations were 19.

Estimation of uncertainties on dose calculations of the 99mTc-MDP-injected patients in nuclear medicine.

The internal exposures of the patients in nuclear medicine can be calculated based on the equations and data in ICRP Publications 53 and 80. Physical and biological parameters are used for the calculation, and both include uncertainties. Physical parameters can be considered as more precise than biological parameters, so that uncertainties originated from biological parameters are more important.

Extra virgin olive oil increases uncoupling protein 1 content in brown adipose tissue and enhances noradrenaline and adrenaline secretions in rats.

The effects of extra virgin olive oil (EV-olive oil) on triglyceride metabolism were investigated by measuring the degree of thermogenesis in interscapular brown adipose tissue (IBAT) and the rates of noradrenaline and adrenaline secretions in rats, both in vivo and in situ. In Experiment 1 (in vivo), rats were given an isoenergetic high-fat diet (30% fat diet) containing corn oil, refined olive oil, or EV-olive oil. After 28 days of feeding, the final body weight, weight gain, energy efficiency, perirenal adipose tissue and epididymal fat pad and plasma triglyceride concentrations were the lowest in the rats fed the EV-olive oil diet.
