A bovine rotavirus, NGRBg8, isolated from the feces of a calf with diarrhea in Nigeria was characterized by reverse transcription-PCR, nucleotide sequence analysis, and Northern blot hybridization. The nucleotide sequence of the VP7 gene of the strain was most closely related to that of a Nigerian human G8-serotype strain, HMG035 (99.9%). The NSP1 gene of strain NGRBg8 is highly related (99.4%)...

pod length is one of the effective components on canola yield selection on the basis of which can increase not only the seed yield but also the oil yield. molecular markers asso-ciated with long pod loci were identified in a doubled haploid population derived from a cross between the canola lines ‘quantum’ (long pod) ‘china a’ (short pod) using rapd and bulked segregant analysis. a molecular ma...

equilibrium geometry, electronic structures, and vibrational modes of cob8- were investigated in the pbepbe/6-311+g(d,p) level of theory. the nucleus independent chemical shift (nics) analysis and magnetizability values were used for studying of aromaticity in cob8-. the effects of different solvents on the structure and frontier orbital energies were calculated using the polarizable continuum ...

Numerous prior studies have indicated that viable rotavirus reassortants containing structural proteins of heterologous parental origin may express unexpected phenotypes, such as changes in infectivity and immunogenicity. To provide a structural basis for alterations in phenotypic expression, a three-dimensional structural analysis of these reassortants was conducted. The structures of the reas...

Two distinct subtypes of human rotavirus serotype 4 were identified by using neutralizing monoclonal antibodies directed to the major outer capsid glycoprotein, VP7, of strains ST3 (subtype 4A) and VA70 (subtype 4B). Specimens containing serotype 4 rotavirus, obtained from different countries, were examined for subtyping by using solid-phase immune electron microscopy, enzyme-linked immunosorbe...

Nucleotide and deduced amino acid sequences of the outer capsid proteins VP4 and VP7 of a murine rotavirus strain (YR-1) isolated in Japan were determined. Comparisons of the VP7 amino acid sequence of YR-1 with other murine rotavirus strains (EB, EW, EC, EL and EHP) (1) showed that YR-1 was highly homologous to EB, EW, EC, EL and EHP. Moreover, YR-1 was more closely related to strains represen...

During February and March 2005, one of the largest national recorded outbreaks of severe acute gastroenteritis occurred in Nicaragua, affecting >or=64,000 individuals and causing >or=56 deaths, predominantly in children under 5 years of age. Through a nationwide laboratory-based study, stool samples were collected and investigated for rotavirus. Of 108 stool samples examined, 72 (67%) were posi...
