background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...

The effect of cold exposure (0 degrees C) on profiles of total heat production (HP), energy metabolism, and blood metabolite and hormone concentrations were measured in nine shorn Suffolk rams. Blood metabolite and hormone responses to feeding and to i.v. arginine injection (.625 mmol/kg BW) and postprandial changes in HP were also measured. Heat production was greater (P < .05) during cold exp...

OBJECTIVE To study a method of chemical sterilization and its efficacy in adult male stray dogs. METHODS Sterilization was performed 45 days after a single bilateral intratesticular injection of calcium chloride (CaCl(2)) at the doses of 5, 10, 15 or 20 mg per testis per kg body weight. RESULTS Histomorphological measures of testes showed total necrosis of testicular tissue at 45 days after...
