background and aims: congenital anomalies are as the major causes of stillbirths, neonatal death, disability and childhood health problems all over the world. the aim of this study was to determine the incidence and pattern of congenital anomalies in newborn during the first 24 hours of life in shahid-madani hospital, azarshahr, tabriz, during two periods 2002-2003 and 2012-2013 years. methods:...

OBJECTIVE To estimate prevalence and risk factors for International Labour Organization radiographic abnormalities, and assess relationship of these abnormalities with spirometry results in former Department of Energy nuclear weapons workers. METHODS Participants were offered chest x-ray (CXR) and lung function testing. Three occupational medicine physicians read CXRs. RESULTS Forty-five (5...

Mitochondrial OXPHOS disorders are caused by mutations in mitochondrial or nuclear genes, which directly or indirectly affect mitochondrial oxidative phosphorylation (OXPHOS). Primary mtDNA abnormalities in children are due to rearrangements (deletions or duplications) and point mutations or insertions. Mutations in the nuclear-encoded polypeptide subunits of OXPHOS result in complex I and II d...

a case with two simultaneous dens invaginations (dis) and one dens evagination (de) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. de known as talon cusp of the anterior teeth is a rare entity and its co-existence with di has been reported scarcely in the literature. simultaneous occurrence of two dis with one de has not been reported elsewhere. u...

With the advent of transgenic pigs using the somatic cell nuclear transfer (SCNT), SCNT pig was thought to hold great promise in basic research, as well as in agricultural and biomedical applications, including xenotransplantation [1,2]. However, SCNT in pigs is limited by substantial problems with the current technologies, including extremely low efficiency, early embryonic and fetal mortality...

Translocations involving the HRX/ALL1 locus at chromosomal region 11q23 are among the most frequent cytogenetic abnormalities in acute leukemias. 11q23 translocations involve different chromosome partners and lead to the formation of HRX/ALL1 fusion proteins. The HRX/ALL1 protein is a putative transcription factor that has been implicated in developmental regulation in mammals. We report here t...

The micronucleus (MN) assay on exfoliated buccal cells is a useful and minimally invasive method for monitoring genetic damage in humans. To determine the genotoxic effects of calcite dust that forms during processing, MN assay was carried out in exfoliated buccal cells of 50 (25 smokers and 25 non-smokers) calcite factory workers and 50 (25 smokers and 25 non-smokers) age- and sex-matched cont...
