we present the first reported case of antiphospholipid syndrome with stroke in an iranian boy (7-month-old) who had two ischemic strokes within a period of 2 months. serum anticardiolipid antibody was positive and the patient had low levels of protein s and c. this case emphasizes the importance of antiphospholipid antibody in children with unexplained ischemic stroke.

animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. nitrogen has been identified as the foremost source of nonpoint water pollution  and the potential negative impacts of n have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing aa supply to the duodenum. ruminal proteolysis...

Thermal denaturation of a-Lactalbumin in the absence and presence of various concentrations of sucrose,sorbitol, glucose and galactose as sugar osmolytes were measured by monitoring changes in the absorptions thatcarried out in a Lambd 35 UV-Vis double beam spectrophotometer at pH 6.0. These measurements gave valuesof T., (midpoint of denaturation), AH., (enthalpy change at T.), and ACp (consta...

background: it seems that the success of vaccination for cancer immunotherapy such as dendritic cell (dc) based cancer vaccine is hindered through a powerful network of immune system suppressive elements in which regulatory t cell is the common factor. foxp3 transcription factor is the most specific marker of regulatory t cells. in different studies, targeting an immune response against regulat...

synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants the concept of synchronization energy and protein was first by jhonson, implying that maximum microbial protein synthesis could be achieved by matching the rate of organic matter and protein degradation. synchronization of rumen available...

diphtheria is a fatal disease caused by exotoxin of corynebacterium     diphtheria .  this toxin consists of   two chains, catalytic chain (a) and binding (b) chain. by binding chain (b),   the toxin binds to its receptor on numerous body cells such as myocardial,   kidney and peripheral nerve cells. after entering, catalytic chain (a)   inhibits protein synthesis and finally can cause cell dea...

The aim of this study is to identify, clone and express a Mycobacterium avium subsp. paratuberculosis specific immunogenic antigen candidate, in order to develop better reagents for diagnosis and vaccines for the protection of the host. Therefore, MAP2191 gene (a member of MAPmce5 operon) from MAP, was isolated and characterized by Bioinformatics tools and <e...

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...
