Background: Chest x-ray has an important role in the diagnosis of tuberculosis (TB). The aim of this study was to determine the radiological changes in patients with smear positive pulmonary tuberculosis.Methods: In this study, 325 patients with smear positive pulmonary TB was enrolled. The affected lobe or lobes of the left or right lung were recorded. The types of involvement were categorized...

During the bull-nose end milling operations of thin-walled structures, chatter usually occurs and adversely affects cutter performance, finished surface quality, production efficiency. To accurately predict stability, a suitable dynamic model with effective system parameters is required. In this article, three-degree-of-freedom (3-DOF) developed to analyze stability cylinders, in which dynamics...

Patients with temporal lobe epilepsy have inexplicable fear attack as the aura. However, the underlying neural mechanisms of seizure‐modulated fear are not clarified. Recent studies identified stathmin as one of the key controlling molecules in learning and innate fear. Stathmin binds to tubulin, inhibits microtubule assembly and promotes microtubule catastrophes. Therefore, stathmin is predict...

Introduction: Paranormal beliefs are defined as believing in extrasensory perception, precognition, witchcraft, and telekinesis, magical thinking, psychokinesis, superstitions. Previous studies corroborate that executive brain functions underpin paranormal beliefs. To test causal hypotheses, neurophysiological studies of brain activity are required. Method: A sample of 20 students (10 females,...

background and objective: temporal lobe epilepsy (tle) usually leads to memory deficit. in this study, we tried to assess the effect of withania somnifera extract on the impaired learning and memory in the intrahippocampal kainate model of tle in the rat. materials & methods: male rats (n=32) were divided into sham, extract+sham, kainite, and kainite+extract. for induction of epilepsy, uni...

Background & objectives: Prognosis of thyroid papillary cancer is quite well long lasting, so a 10- year survival is observed in more than 90% cases. In this study, rate of incidence of thyroid papillary cancer in contralateral lobe was assessed among patients who had a surgical thyroidectomy re-operation. Materials & Methods: In this retrospective study, we examined 82 patients diagnosed with...

Microtubule Affinity-Regulating Kinase 2 (MARK2) protein has a substantial role in regulation of vital cellular processes like induction of polarity, regulation of cell junctions, cytoskeleton structure and cell differentiation. The abnormal function of this protein has been associated with a number of pathological conditions like Alzheimer disease, autism, several carcinomas and development of...
