conclusions il6 and il8 gene polymorphisms have no role in nash pathogenesis and liver fibrosis process, but presence of the a/a genotype in the il8 gene is associated with disease progression. patients and methods consecutive patients with biopsy proven nash and age- and gender-matched healthy individuals with normal liver function tests and normal ultrasonography were enrolled in the study. h...

background: the goal of the present work was to determine frequencies of different finger patterns of a population in hamadan (one of the western cities of iran) in 1997. methods: in a cross-sectional study, the .prints of the first phalanx of both hands of 717 randomly selected hamadan students (i88 men, 529 women) have taken, by using standard method (stamp ink). the fingerprints were classif...

background:in the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded rna viruses from cdna or viral minigenomes. this technique has been applied to study different steps in virus replication and virus-host interactions. reverse genetics could also be implemented for design of new vaccines. the t7 rna polymerase activity as well as virus (nucleocapsi...

the overwhelming rate of progress in biotechnological research especially in human genetics, as well as the high levels of power these researches provide us to intervene in human lives, brings serious concerns on the ethical problems that may rise from these research endeavors. to address this critical issue in iran, we conducted a study issuing publishing authors of studies in human genetics f...

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...

this paper presents a model for constrained multiobjective optimization of mixed-cropping planning. the decision challenges that are normally faced by farmers include what to plant, when to plant, where to plant and how much to plant in order to yield maximum output. consequently, the central objective of this work is to concurrently maximize net profit, maximize crop production and minimize pl...

proper scheduling of tasks leads to optimum using of time and resources, inorder to obtaining best result. one of the most important and complicatedscheduling problems is open shop scheduling problem. there are n jobs in openshop scheduling problem which should be processed by m machines. purpose ofscheduling open shop problem is attaining to a suitable order of processing jobs byspecified mach...
