BACKGROUND AND AIM: Due to increasing use of X-rays in diagnosis and treatment of diseases, this study aimed to measure and compares the absorbed dose in a number of sensitive organs of head and neck in different radiographic techniques.METHODS: Thermoluminescence dosimeter (TLD) and a male equivalent RANDO phantom were used to measure the absorbed dose in organs. The dosimeters were set in cer...
Background: Ionizing radiation is present in all environment of the Earth’s surface, beneath the Earth and in the atmosphere. Human beings are exposed to external radiation from their surroundings naturally and also to internal radiation from food, water and air they consume. Then, it is important to measure and develop knowledge about radiation. Objective: This study is designed to evalu...

Pasireotide is a novel multireceptor ligand somatostatin analog that improves biochemical control of humans with HST. HYPOTHESIS/OBJECTIVES Pasireotide improves biochemical control of HST and diabetes mellitus in cats. ANIMALS Hypersomatotropism was diagnosed in diabetic cats with serum insulin-like growth f...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
A single dose, crossover bioequivalence study of two different brands of clonidine hydrochloride 25 mug tablets was conducted in 24 (+2 stand by) healthy, adult, male, Indian subjects under fasting conditions to check the implication of enterohepatic re-circulation on assessment of bioequivalence. After an overnight fasting of at least 10 h, the subjects received single oral dose of test or ref...
Aim: Interventional radiology procedures using ionizing radiation were frequent and become more and more complex. While determinants of radiation exposure during coronary angioplasty have been examined intensively during the last decade, available data regarding peripheral interventional procedures and especially the influence of pre-interventional diagnostic procedures on radiation exposure ar...
