background: fine needle aspiration (fna) has led to a decrease in unnecessary surgeries for thyroid nodules. this study was designed to compare diagnostic value of fna and frozen section methods in the follicular lesions. methods: this is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of rasool-e-akram hospital in tehran with complaint of...

thrombotic thrombocytopenic purpura is the result of multiple thrombus disseminated in small arterioles throughout the body. principle damage is in the endothelium of small vessels and capillaries. from 1982 to 1999, 28 patients (16 female and 12 male) have been treated for ttp. the outcome was evaluated for risk factors and prognosis. these patients were 18 to 69 years old. all had neurologica...

BACKGROUND Artificial calcanei, fresh-frozen cadaver specimens, and embalmed cadaver specimens were compared in experimental testing under biocompatible loading to clarify the biocompatibility of artificial calcaneal specimens for implant testing. METHODS Two different artificial calcaneal bone models (Sawbone, Pacific Research Laboratories, Vashon, WA, and Synbone, Synbone Inc., Davos, Switz...

Background: The quality and safety of fish products is determined by chemical, physical, and microbiological parameters, important for satisfying consumers’ requirements. Also, the freshness of fish is essential for evaluation of its quality. On the Bulgarian retail market, fish is commonly offered chilled, frozen, or processed. The purpose of this study was to determine some physicochemi...

We previously demonstrated that testicular spermatozoa can be preserved as frozen testicular sections, allowing us to preserve male gametes in less space than conventional methods. However, it remains unclear whether the testicular spermatozoa can be preserved for a long period using this procedure. In this study, we examined the function of testicular spermatozoa preserved as frozen testicular...
