Although the size of an organism is influenced by many features of its environment, the relationship between temperature and body size has captivated generations of biologists. From the renowned observations by Bergmann (1847) to the phylogenetic comparative studies by our contemporaries (e.g., Ashton et al., 2000), evidence of a widespread relationship between temperature and adult body size h...

Dystrophin deficiency in skeletal muscle of the x-linked dystrophic (mdx) mouse can be partially remedied by implantation of normal muscle precursor cells (mpc) (Partridge, T. A., J. E. Morgan, G. R. Coulton, E. P. Hoffman, and L. M. Kunkel. 1989. Nature (Lond.). 337:176-179). However, it is difficult to determine whether this biochemical "rescue" results in any improvement in the structure or ...

Chromatographic separations of amino acids on ion exchange resins may be performed on a preparative scale either by elution (24) or by displacement (5-12). Some of the exceptional resolving power demonstrated in analytical separations by elution techniques (13, 14) disappears when larger columns with relatively higher loads are used (2). Displacement chromatography allows large quantities of so...

Our goal was to document effects of year-round supplemental feeding on breeding ecology of the Buff-throated Partridge, Tetraophasis szechenyii, within a Tibetan sacred site. We evaluated effects of supplemental feeding used as religious/cultural practices which could potentially aid conservation of endangered phasianids. We compared fed breeding groups to neighboring nonfed groups. Fed groups ...

The initial interaction between viral attachment proteins and the host cell is a critical determinant for the susceptibility of a host for a particular virus. To increase our understanding of avian pathogens and the susceptibility of poultry species, we developed novel avian tissue microarrays (TMAs). Tissue binding profiles of avian viral attachment proteins were studied by performing histoche...

EARLIER work has shown [Morgan, 1937; Morgan & Partridge, 1939, 1, 2; 1940, 1; Partridge & Morgan, 1940] that the antigenic substance which is responsible for the dominant serological properties of the 'smooth' form of Bact. dysenteriae (Shiga) can be extracted from the micro-organism by means of diethyleneglycol. The properties of the antigenic complex were described in some detail and three m...

I N Neurospora crassa a gene cluster encodes a multienzyme aggregate of five enzymes catalyzing steps two through six in the pre-chorismic acid part (Figure 1) of the aromatic synthetic pathway (GILES, CASE, PARTRIDGE, and AHMED 1967a). Two distinct categories of mutants have been detected within this arom cluster: single gene mutants which lack only one of the activities and pleiotropic (“pola...

BACKGROUND Indigenous peoples have traditionally relied on foods hunted and gathered from their immediate environment. The Eastern James Bay Cree people consume wild game and birds, and these are believed to provide health as well as cultural benefits. OBJECTIVE To determine the fatty acid (FA) composition of traditional game and bird meats hunted in the Eastern James Bay area. DESIGN Harve...
