resistance gene analog polymorphism (rgap) markers linked to fusarium head blight resistance (fhb) and co-localize with qfhs.ndsu-3bs were identified using f3 plants and f3:5 lines derived from a ‘wangshuibai’ (resistant) / ‘seri82’ (susceptible) cross. the mapping populations were genotyped using 50 degenerate primers designed based on the known r genes. out of the 50 designed primer combinati...

conclusions the relative higher frequency of some virulence genes in this study may reflect the emergence of isolates containing these genes in shiraz medical centers. background staphylococcus aureus is amongst major human pathogens both in hospitals and the community. this bacterium is an opportunistic pathogen responsible for a large number of self-limiting and even life-threatening diseases...

A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

the objective of this review is to explore the current developments on major genes working on prolific sheep breeds and the mechanism behind it, while identifying the future working points. productivity is the ultimate goal of farm animal production and prolificacy is a key feature in determining productivity in farm animals. ovulation rate in mammals is an intricate process involving genetics ...

avian reoviruses (arvs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. in this study, the molecularcharacteristics of arvs in some broiler breeder flocks were investigated in...

objective(s): we investigated the contribution of gyra and parc mutational mechanism in decreased ciprofloxacin susceptibility of acinetobacter baumannii isolated from burn wound infections. materials and methods: ciprofloxacin susceptibility of 50 a. baumannii isolates was evaluated by disk diffusion and agar dilution methods. pcr and sequencing were performed for detection of mutation in gyra...

The pLE2SCX vector was developed for the stable expression of exogenous genes in the protozoan parasite Leishmania. The pLE2SCX construct contains three independent selection markers: herpes simplex virus thymidine kinase (HSV-TK), cytosine deaminase (CD) and streptothericin acetyltransferase gene (sat) in multiple cloning site, flanking by 5’ and 3’ untranslated regions of the previously clone...

hemophagocytic lymphohistiocytosis (hlh) is an aggressive and potentially life-threatening disease and has to be considered in the differential diagnosis of many conditions. hlh comprises two different conditions that are difficult to differentiate; familial hemophagocytic lymphohistiocytosis (fhlh) or familial erythrophagocytic lymphohistiocytosis (fel), and secondary hemophagocytic syndromes ...
