African nonhuman primate and rodent erythrocytes were tested for agglutination by adenoviruses, reoviruses, and enteroviruses. Squirrel erythrocytes were agglutinated by reovirus serotypes and adenovirus types 3, 11, 16, and 21. Adenoviruses also agglutinated brazza monkey erythrocytes to the same titers as those obtained with either rhesus or grey monkey cells. Prototype reovirus types 1 and 2...

Multiovular follicles have been observed in the ovaries of a number of species, including man, but their mode of origin has remained a matter for speculation (Brambell, 1956). Harrison (1948, 1949) noted increased frequencies of polyovular follicles during the late proliferative phase of the reproductive cycle in goats and squirrel monkeys, and speculated that this change might be related to oe...

This paper shows a comparison simulation results for two controllers using the same name plate of 2750 KW, 6.6 KV, 50 HZ for wound and squirrel cage motors using two methods of controlling, the first method is achieved by a conventional method and the second method is achieved by a frequency inverter respectively. Keywords— Squirrel cage and slip ring motors, conventional and VSD controllers si...

Unique oligonucleotide probes were synthesized to distinguish among closely related vertebrate mitochondrial rDNA sequences present in residual bloodmeals in emergent Amblyomma americanum (L.) (Acari: Ixodidae) nymph life-stage ticks. Use of these probes enabled the identification of the Eastern gray squirrel as an important bloodmeal source in nymphs harboring Ehrlichia and Borrelia species. T...

Antigenicity of IgG was compared among human, the cynomolgus monkey, the African green monkey and the squirrel monkey by the quantitative precipitation test using purified IgG of and rabbit anti-IgG serum to each species. Clear cross-antigenicity was observed between the cynomolgus monkey and the African green monkey and less clear cross-antigenicity between human and the cynomolgus monkey or t...

Recent molecular evidence suggests that Sciurus vulgaris populations from Calabria (southern Italy) are distinct from those occurring in northern and central Italy. Here, we re-analyzed using multivariate and univariate techniques an historical dataset provided by Cavazza (1913), who documented measurements for the now extinct squirrel population from Campania. Both univariate and multivariate ...

Animals that store food must decide which items to eat immediately and which to store for future consumption. Clearly, a starving animal should eat and a satiated animal should store, but other factors must influence this decision in partially satiated foragers. Characteristics of the food could affect the decision; eastern woodrats, Neotoma floridana, eat highly perishable food and store food ...

Primate growth hormone (GH) has evolved rapidly, having undergone approximately 30% amino acid substitutions from the inferred ancestral eutherian sequence. Nevertheless, human growth hormone (hGH) is physiologically effective when administered to nonprimate mammals. In contrast, its functional counterpart, the human growth hormone receptor (hGHR), has evolved species specificity so that it res...

PURPOSE Desensitization in the rod cell of the mammalian retina is initiated when light-activated rhodopsin is phosphorylated by the G protein-coupled receptor kinase (GRK), GRK1, often referred to as rhodopsin kinase. A distinct kinase that specifically phosphorylates cone opsins in a similar manner has not been identified in mammals. To determine the existence of a cone opsin kinase, RNA from...

PURPOSE This study describes the expression and distribution of arrestin, phosducin, and recoverin in the cone-dominant retina of the ground squirrel Spermophilus tridecemlineatus. METHODS mRNA expression was studied by blot hybridization of ground squirrel retinal RNA, with human and murine RNA as controls. The distribution of the gene products in the ground squirrel retina was investigated ...
