conclusions our results suggest that human exposure to mcpyv occurs throughout life. the mcpyv antibody levels remained high among older adults in our population, consistent with reports from other populations. patients and methods in this cross-sectional study, we collected 440 serum samples from healthy individuals 2 to 78 years of age who visited the pasteur institute’s clinic in tehran, ira...

the snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. purification and partial characterization of a thrombin-like enzyme from the venom of the iranian snake, agkistrodon halys, was the aim of this study. purification was carried out by a combination of variety of chromatographic methods that included: gel fil...

  Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...

In this study, the synthesis of ceria (CeO2) nanoparticles (NPs) was examined by the biosynthesis method. Then, enzyme-like features of synthesized nanoceria were examined. Peroxidase enzyme from fig (Ficus carica) was used as a synthesis and stabilizer reagent. Furthermore, it was investigated whether the obtained nanoceria has superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) ac...
