In order to study the seroprevalence of pestivirus infection in small ruminants of Ahvaz at Khouzestan province of Iran, 148 sheep sera and 143 goat sera were randomly collected and tested by seroneutralization. Seroneutralization was performed by NADL strain of Bovine viral diarrhea virus genotype 1. The results indicated the overall seroprevanelces of 46.62% in sheep and 32.871% in goats. Pre...

A number of nicotinamide adenine dinucleotide analogues have been prepared in which the purine, pyridine, and ribose moieties have been modified (2-12). These analogues have proven to be valuable in studies dealing with the site of binding of the pyridine coenzyme to dehydrogenases, in elucidating the mechanism of dehydrogenases and the configuration of the pyridme coenzymes, and as indicators ...

“Good wind and good sea” was a common sentence uttered to sailors and seamen—during the Age of Exploration—before departing on a voyage. It was intended to indicate that wind and sea currents were the two most important elements of nature for reaching a destination. In a metaphorical way, the same words describe the often unknown journey scholars embark on today in digital humanities initiative...

Recently, universal planning has become feasible through the use of efficient symbolic methods for plan generation and representation based on reduced ordered binary decision diagrams (OBDDs). In this paper, we address adversarial universal planning for multi-agent domains in which a set of uncontrollable agents may be adversarial to us. We present two new OBDD-based universal planning algorith...

In this study, we reported the isolation, identification, and molecular characteristics of nine BVDV strains that were isolated from serum persistently infected cattle. The new designated as TJ2101, TJ2102, TJ2103, TJ2104, TJ2105, TJ2106, TJ2107, TJ2108 TJ2109. TJ2102 TJ2104 found to be cytopathic BVDV, other non-cytopathic BVDV. An alignment phylogenetic analysis showed isolates share 92.2–96....

The structure of baculovirus-expressed porcine parvovirus (PPV) capsids was solved using X-ray crystallography and was found to be similar to the related canine parvovirus (CPV) and minute virus of mice (MVM). The PPV capsid protein has 57 % and 49 % amino acid sequence identity with CPV and MVM, respectively, but the degree of conservation of surface-exposed residues is lower than average. Con...

Porcine parvovirus (PPV) is one of the main causes of porcine reproductive failure. It is important for swine industries to understand the recent trends in PPV evolution. Previous data show that PPV has two genetic lineages originating in Germany. In this study, two more genetic lineages were defined, one of which was distinctly Asian. Additionally, amino acid substitutions in European strains ...
