Background and Objective: Methicillin resistant Staphylococcus aureus (MRSA), which is the most common cause of nosocomial infection, has been a major cause of morbidity and mortality around the world. This study was carried out to find out the resistance pattern and staphylococcal cassette chromosome mec (SCCmec) typing among MRSA. Materials and Methods: This descriptive work was done on 87 Me...
Introduction: Burkitt lymphoma is an aggressive subtype of Hodgkin lymphoma with a doubling time of 25 hours. It is characterized by a MYC gene coding alteration which results from a translocation of chromosome 8 on the MYC gene locus and immunoglobulin heavy-chain locus (IGH) on chromosome 14. Even though HIV infection is associated to an increased risk of Burkitt lymphoma, th...
رفتار میوزی برای اولین بار در زیر گونه crocus cancellatus subsp. damascenus (سیتوتیپ 2n=8a ) گزارش می شود. نتایج نشان می دهد که این زیر گونه (سیتوتیپ 2n=8a) دارای مجموعه کروموزومی 2n=8 و عدد گامتی n=4 می باشد. دو جفت کروموزوم به هستک متصل بود که تایید کننده حضور دو جفت کروموزوم قمردار در این زیر گونه می باشد. حضور یک عدد b کروموزوم در هر دو مرحله میوز و میتوز در این سیتوتیپ برای اولین بار گزارش...
We conducted an autosomal genome scan to map loci for type 2 diabetes in a Hong Kong Chinese population. We studied 64 families, segregating type 2 diabetes, of which 57 had at least one member with an age at diagnosis of </=40 years. These families included a total of 126 affected sibpairs and 4 other affected relative pairs. Nonparametric linkage analysis revealed seven regions showing nomina...
Chromosomal rearrangements occur more frequently in subtelomeric domains than in other regions of the genome and are often associated with human pathology. To further elucidate the plasticity of subtelomeric domains, we examined the 3.3 kb D4Z4 repeat array on chromosome 4 and its homologue on chromosome 10 in 208 Dutch blood donors by pulsed field gel electrophoresis. These subtelomeric repeat...
Mating-type switching in yeast occurs through gene conversion between the MAT locus and one of two silent loci (HML or HMR) on opposite ends of the chromosome. MATa cells choose HML as template, whereas MATα cells use HMR. The recombination enhancer (RE) located on the left arm regulates this process. One long-standing hypothesis is that switching is guided by mating-type-specific and possibly ...
To examine whether biomarkers such as sister chromatid exchanges (SCEs) and chromosome aberrations (CAs) can predict cancer development, a nested case-control study was performed in a blackfoot endemic area with a known high cancer risk. A cohort of 686 residents was recruited from three villages in the blackfoot endemic area. Personal characteristics were collected, and venous blood was drawn ...
