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...

statement of problem: due to the appearance of palatal height difference in orthodontic patients we decided to carry out this study. purpose: the purpose of this research was to determine palatal height in persons with normal occlusion and different malocclusions (class i, ii div i and iii) and comparing them with each other. materials and methods: in this cross sectional research, 240 subjects...

How pre-ribosomes temporally and spatially mature during intranuclear biogenesis is not known. Here, we report three nucleolar proteins, Noc1p to Noc3p, that are required for ribosome maturation and transport. They can be isolated in two distinct complexes: Noc1p/Noc2p associates with 90S and 66S pre-ribosomes and is enriched in the nucleolus, and Noc2p/Noc3p associates with 66S pre-ribosomes a...

An epizootic disease in pigeons associated with atypical pneumonia in two persons handling the birds has been studied. Most of the observations made during the work were consistent with the idea that we were dealing with an infection caused by a member of the psittacosis-lymphogranuloma venereum group of viruses. The outbreak was peculiar, however, in that tissues of the diseased pigeons contai...

BACKGROUND The capacity for herpesvirus to cause disease in cetaceans is unclear and may be varied depending on the different conditions of individuals and between different species. Kidney pathology and intralesional virus-associated infection have been rarely reported in cetaceans. RESULT On April 2004, an old adult male Blainville's beaked whale (Mesoplodon densirostris) 420 cm long with a...

Tracking humans is a diicult problem because of the non-rigid nature of the human body, and the frequent occlusion encountered among people. We present a framework to track multiple people in a xed camera situation. Our framework deals implicitly with occlusion, and is able to correctly label people during occlusion. We rst segment a person into classes of similar color using the Expectation Ma...

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...

SUMMARY An intranuclear canalicular system connecting the nuclear envelope to the nucleolus has been found in interphase cells of the Novikoff hepatoma in both the ascitic and the solid forms. Throughout the nucleoplasm, flattened canaliculi are seen in sections as parallel membranes covered by thin layers of chromatin material. Membrane-bounded tubules exist in direct contact with the nucleolu...
