statement of problem: nowadays, evaluation of the development of occlusion in deciduous teeth for creating corrective occlusion in permanent teeth is one of the most important objectives of pediatric dentistry. in other countries, a vast number of researches have been accomplished on the details of occlusion in deciduous teeth. but, unfortunately, there is still no accurate information about th...

An analysis of the electrocardiograms from 25 patients during reduction of body temperature and total occlusion of circulation reveals marked abnormalities in conduction and rhythmicity. Hypothermia was accompanied by slowing of the heart rate, depression of intracardiac conductivity, and by inhibition of the normal centers of impulse formation with resultant atrial arrhythmias. Circulatory occ...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

MicroRNAs are non-coding RNAs. Studies have shown that miRNAs are expressed aberrantly in stroke. MiR-1 enhances ischemic damage, and previous study has demonstrated that reduction of miR-1 level has neuroprotective effect on Middle Cerebral Artery Occlusion(MCAO). Since apoptosis is one of the important process in neural protection, possible effect of miR-1 on this pathway has been tested in t...

background: caucasian norms are still used in the orthodontic treatment of iranian patients, despite the different ethnic backgrounds of iranians. the aims of this study were to evaluate the cephalometric features of an iranian population and to establish cephalometric norms for iranian living in the central region of iran (isfahan). materials and methods: a total of 238 lateral cephalometric r...

PURPOSE Retinal oxygen tension (PO2), photoreceptor oxygen consumption (QO2), the local electroretinogram (LERG), and the vitreally recorded electroretinogram (ERG) were evaluated during retinal artery occlusion in the cat. The feasibility of supplying the retina with oxygen during occlusion by ventilation with 100% O2 was evaluated. METHODS Double-barreled oxygen microelectrodes were used to...
