Two experiments were conducted to evaluate the effect of testosterone on growth and composition of cattle. In the first experiment, crossbred yearling heifers (n = 48) were assigned to four treatments: 1) control (no implant), 2) Synovex-H implants on d 1 and 84, 3) one testosterone propionate implant administered on d 1 and a second on d 84 and 4) two testosterone propionate implants administe...

objective: predoctoral dental implant education is included in dental school teaching curricula in most of the developed and some developing countries; however, it was not introduced into undergraduate curriculum of some countries and iranian dental schools. our purpose was to investigate the status of the predoctoral dental implant education of dental schools in the world. materials and method...

background: titanium (ti) implants are commonly coated with hydroxyapatite (ha). however, ha has some disadvantages such as brittleness, low tensile strength and fracture toughness. it is desirable to combine the excellent mechanical properties of zro2 and the chemical inertness of al2o3 with respect to the purpose of this project which was coating ti implants with ha-zro2-al2o3 to modify the s...

results sixteen patients (66.7%) in antibiotic group and 20 patients (90.9%) in placebo group had post-operative swelling and pain. the average pain in the antibiotic and placebo groups were (31.04 + 26.29) and (37.73 + 23.69) respectively, and the difference was not statistically significant (p value = 0.37). one patient in each group had probing depth between 5 to 7 mm in six months after sur...

BACKGROUND AND AIM: Information gathered from patients about dental implants is often incomplete and scattered. The aim of the present study was to measure the level of this information and the attitudes of patients seeking dental implants.METHODS: In the present cross-sectional descriptive-analytic study, 248 people were employed. To discover the level of knowledge and attitudes in dental impl...

Perforator flaps represent the latest in the evolution of soft tissue flaps. They allow the transfer of the patient’s own skin and fat in a reliable manner with minimal donor-site morbidity. The powerful perforator flap concept allows transfer of tissue from numerous, well-described donor sites to almost any distant site with suitable recipient vessels. The inferior gluteal artery perforator (I...

Novel, clinically relevant, approaches to shift energy balance are urgently needed to combat metabolic disorders such as obesity and diabetes. One promising approach has been the expansion of brown adipose tissues that express uncoupling protein (UCP) 1 and thus can uncouple mitochondrial respiration from ATP synthesis. While expansion of UCP1-expressing adipose depots may be achieved in rodent...
