background: plasmodium vivax is responsible for approximately 80 million malaria cases in the world. apical membrane antigen1 (ama-1) is a type i integral membrane protein present in all plasmo­dium species. ama-1 interferes in critical steps of invasion of human hepatocytes by sporo­zoites and red blood cells by merozoites and is one of the most immunodominant antigens for elicit­ing a protect...

the protective capacity of the crude extracts from larval and nymphal stages of hyalomma anatolicum anatolicum was examined in the new zealand white rabbits. the rabbits were randomly divided into 3 groups of five animals. the rabbits in groups 1 and 2 were immunized with crude extracts of larval and nymphal antigens, respectively and group 3 was served as control. following challenge of each r...

We present microscopic and macroscopic magnetic properties of the highly frustrated antiferromagnet Ba(2)Sn(2)ZnCr(7p)Ga(10-7p)O22, respectively, probed with NMR and SQUID experiments. The T variation of the intrinsic susceptibility of the Cr3+ frustrated Kagomé bilayer, chi(Kag), displays a maximum around 45 K. The dilution of the magnetic lattice has been studied in detail for 0.29</=p</=0.97...
