Background: The tumor suppressor gene TP53 (alias p53) located on chromosome 17 is involved in various cancers. Case-control studies have shown that p53 codon 72 polymorphism modulates the prognosis and susceptibility to various malignancies. We undertook the present study to explore a possible association between mucinous and non-mucinous adenocarcinomas with different genotypes or alleles at ...
The melanocortin-1 receptor (MC1R) gene has been investigated by many studies regarding the pigmentation variation in various species. In order to determine its allelic and genotypic distribution, we sequenced the goat MC1R gene from 78 individuals in ten populations (Gembrong, Senduro, Ettawa Grade, Boerawa, Boerka, Kosta, Samosir, Muara, Boer and Kacang). Direct sequencing m...
Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, with a complex etiology that includes a strong genetic component. The chromosome 19q 13 region surrounding the apolipoprotein E (APOE) gene has shown consistent evidence of involvement in MS. In a cross-sectional study, to show the APOE genotype and allele frequency in the MS population of Iran in comp...
angiotensin converting enzyme (ace; omim: 106180) has an important role in the conversion of angiotensin i to angiotensin ii and degradation of bradykinin. genetic polymorphism i/d (rs4646994) in the gene encoding ace has been well defined. to get more insight into the genetic structure of iranian populations, the distribution of the ace i/d polymorphism among iranians was compared with each ot...

مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
