Background and Objective: According to the fact that neonatal infection is a challenging diagnosis field, several studies have tried to test sensitivity and specificity of diagnostic tests. This study was conducted to evaluate the sensitivity and specificity of procalcitonin (PCT) as a single early marker of neonatal sepsis. Materials and Methods: In this study, 150 neonates admitted to NIC...

background patients presenting with a mass require tissue biopsy for histological diagnosis and treatment. fine needle aspiration (fna) is offered as an atraumatic, well tolerated, and inexpensive method for obtaining a biopsy from these lesions. objectives in this study we evaluated the accuracy of fna as an atraumatic method among patients with nonthyroidal masses for diagnosis of neoplastic ...

Early in this study, an α-Amylase from Bacillus megaterium WHO (BMW) was isolated from hot springs of Ramsar (North of Iran), and its gene was cloned in E.coli. Based on its conserved sequence regions and substrate specificity, it was classified as intermediary group enzymes with the specificity of oligo-1,6-glucosidase and neopullulanase subfamilies. In the sixth conserved re...

background and aim: otoacoustic emissions (oae) and automated auditory brainstem response (aabr) are the most commonly-used methods for universal neonatal hearing screening (unhs). various sensitivity and specificity rates have been reported for the oae and aabr tests as tools for screening newborn hearing. the main objective of this review was to determine the pooled sensitivity and pooled spe...

in this study granulocyte-macrophage colony stimulating factor (csf) was prepared from rabbit and guinea pig lung tissues. the biological activity of these csfs was measured on semisolid agar culture and compared with those of mouse and rat. weight of animals, incubation time and cross-reactivity of csfs with different bone marrow sources were also investigated. the results showed that both rab...

introduction: group a beta-hemolytic streptococcus (gabhs) can induce pandas (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). gabhs is the most important and common bacterial cause of acute pharyngitis in iranian children. we studied the role of gabhs (anti-streptococcal antibodies) in suspected cases of pandas in a cross sectional studies. methods: acr...

recently, researches on motor learning have illustrated that learning with effortless process supports learning under psychological stress. also, contextual interference and practice specificity theories are among those theories which investigate desired practice conditions. the current study aimed at identifying cognitive effort and effortless process based on contextual interference and pract...
