<Anopheles culicifacies is a main malaria vector in southeastern part of Iran, bordring Afghanistan and Pakistan. So far, resistance to DDT, dieldrin, malathion and partial tolerance to pyrethroids has been reported in An. stephensi, but nothing confirmed on resistance status of An. culicifacies in Iran. Methods: In current study, along with WHO routine susceptibility test with DDT (4%), di...
The thermostability of Flavobacterium meningosepticum glycerol kinase was increased by the change from Ser329 to Asp [Protein Eng., 14, 663-667 (2001)]. Based on a three-dimensional structure model of the mutant, we have postulated that a new charged-neutral hydrogen bond was formed between Asp329 and Ser414, and the formation of the hydrogen bond contributed to the stabilization of the tertiar...
Abstract Background and Objectives Thalassemia is a group of inherited hemoglobin disorders with defect in the synthesis of hemoglobin chains. Case The young couple resident in Bandar Abbas, a 23 year old woman with MCV:63fl; MCH:19; HbA2:3.9 and a 25 year old man with MCV:94fl; MCH:32; HbA2:2.1; HbF:36, were referred to the Bandar Abbas Medical Genetic & PND Center for genetic counsell...
Allelic Diversity of Major Histocompatibility Complex Class II DRB Gene in Indian Cattle and Buffalo
The present study was conducted to study the diversity of MHC-DRB3 alleles in Indian cattle and buffalo breeds. Previously reported BoLA-DRB exon 2 alleles of Indian Zebu cattle, Bos taurus cattle, buffalo, sheep, and goats were analyzed for the identities and divergence among various allele sequences. Comparison of predicted amino acid residues of DRB3 exon 2 alleles with similar alleles from ...
The double-stranded RNA-dependent protein kinase (PKR) is induced in mouse and human cells on treatment with interferon. In this study, we have cloned and determined the nucleotide sequences of chicken PKR cDNA in various chicken breeds. Chicken PKR was a 550-amino-acid protein as deduced from the cDNA open reading frame (ORF), and there were specific domains (two double-stranded RNA binding do...
