Collins (1985) has described two separate mouse strains, obtained by selective breeding, which differ in having high (HI) or low (LO) degrees of paw preference on a standard test. In this paper I argue that the differences between these strains may not be due to a specific gene (or genes) but, instead, probably reflect differences in the total heterozygosity of the strains, such that the HI str...

Sera from various wild ruminants co-existing in the same habitats with cattle had haemagglutination-inhibition (HI) antibodies as high as those in the cattle. Sera from wildebeest (Connochaetes taurinus), kongoni (Alcelaphus cokei), Thomson’s gazelle (Gazella thomsonii), eland (Taurotragus oryx) and the African buffalo (Syncerus caffer) had titers ranging from 64 to 128. Zebra (Equus burchelli)...

Hearing-aid wearers have reported sound source locations as being perceptually internalized (i.e., inside their head). The contribution of hearing-aid design to internalization has, however, received little attention. This experiment compared the sensitivity of hearing-impaired (HI) and normal-hearing listeners to externalization cues when listening with their own ears and simulated behind-the-...

Background and Aim: Hearing impairment is a leading challenge in the education of deaf children. Compared to normal children, hearing-impaired (HI) children have poor oral health due to a lack of communication skills and effective health educations. This leads us to search for a proper method to educate these children. The present study aimed to assess the effect of different educational method...

Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent was a low-pathogenicity H9N2 avian influenza virus that caused frequent episodes of high mortality in broiler chicken farms in Iran and some other Asian countries. This study was designed to investigate the prevalence of AIV H9N2 subtype in commercial chicken flocks in Dezful, southern Iran...

Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/ Gallinarum. Positive samples were submitted to hemagglutination inhib...

OBJECTIVES Several different methods are currently used to detect antibodies to Japanese encephalitis virus (JEV) in serum samples or cerebrospinal fluid. These methods include the plaque reduction neutralization test (PRNT), the hemagglutination inhibition (HI) test, indirect immunofluorescence assay (IFA), and enzyme-linked immunosorbent assay (ELISA). The purpose of this study was to compare...

Main aim is to evaluate the genotoxic potentials of three classes of natural products, a sesquiterpene lactone (cynaropicrin), a saponin (stigmast-7en-3 -ol-glucopyranoside) and a steroid (stigmasterol), at low doses, using the Homozygotization Index test (HI). This short-term test, deals with the determination of alterations in mitotic crossing-over frequencies eventually involving heterozygou...
