One male infant was observed from the day of his birth to the end of the 6th month. Total observation days were 171 days, and total observation time was 329 h 25 min and 35s. Five hundred and sixty-five spontaneous smiles and 15 spontaneous laughs (smiles accompanied by vocal sounds) were observed. Developmental psychologists have thought that spontaneous smiles integrate at about 3 months, but...

Surgery is the treatment of choice for symptomatic disc herniation after conservative management. Several studies have suggested potential utility intradiscal ozone infiltration in this pathology. The aim trial was to compare vs. oxygen surgery. This a randomized, double-blinded, and controlled patients on waiting list herniated There were three groups: surgery; (plus foraminal ozone, steroids,...

purpose: to evaluate the efficacy of subtenon injection of botulinum toxin a (dysport) in acute 6th nerve palsy. methods: this randomized clinical trial was performed on 28 patients with 6th nerve palsy of less than 3 months’ duration without history of extraocular muscles abnormality. ophthalmic examinations included visual acuity, degree of eye deviation, slitlamp biomicroscopy and funduscopy...

INTRODUCTION The study seeks to investigate how the duration of storage of cryopreserved human cadaveric iliac arteries impacts their mechanical, structural and microbiological properties as compared to their fresh sample. MATERIALS AND METHODS Iliac arteries were harvested from 12 human cadavers and divided into 2 groups. One group underwent mechanical stress-strain assessment immediately an...

Introduction: Ultra low dose (ULD) morphine induces hyperalgesia which is mediated by excitatory Gscoupled opioid receptors. This study was designed to investigate the development of tolerance to hyperalgesic effect of morphine. Also we attempt to seek possible similarity, in view of Gs proteins, between hyperalgesic effect of ULD and hyperalgesic effect after tolerance to HD. Method: Male ...

Introduction: Pheromones play a great role in the reproductive and social behavior of animals. The main sources of pheromones are urine and paracrine secretions. Through the neuroendocrine system, prolactin is a safe parameter to measure and compare the effects of pheromones on the sexual, maternal and also lactating behavior. Methods: Female rats were divided into 19 groups (n=8). To measur...
