Species Specific Pharmacokinetics of Rolitetracycline

Journal of Veterinary Medicine Series A, 1995
SummaryComparative studies on some selected pharmacokinetic parameters of rolitetracycline (effective antimicrobial activity levels) in sheep, pigs, rabbits, chickens and pigeons were carried out after intravenous administration of the drug at a dose of 5 mg/kg. The results revealed that a two‐compartment open model was usually optimal.

Species Specificity in Fertilization

1974
In his classical monograph, Problems of Fertilization, Lillie (1919) devoted a chapter to the problem of specificity in fertilization which, nearly 40 years later, Rothschild (1956) commended to all students of fertilization. In summing up his own chapter on “Specificity”, Rothschild considered the only advances to have been made since Lillie’s ...

Species specificity in mouse glycophorin

Biochemical and Biophysical Research Communications, 1991
89, 65, 46 and 29 Kd mouse glycophorin proteins identified during polyacrylamide electrophoresis of mouse erythrocytes have been further characterized. These proteins (1) stain positive with Periodic Acid Schiff reagent after sodium hydroxide treatment; (2) labeled using [125I] in intact cells; (3) co-isolated along with integral membrane proteins in ...

Species-Specific Myoglobin Oxidation

Journal of Agricultural and Food Chemistry, 2011
The effect of the lipid oxidation product, 4-hydroxy-2-nonenal (HNE), on oxidation of oxymyoglobin (OxyMb) from seven different meat-producing species was investigated. Relative to controls, HNE increased OxyMb oxidation within all species (p < 0.05) at both 25 and 4 °C, pH 5.6. The relative effect of HNE was greater for myoglobins (Mbs) that contained

Gamete interaction: Is it species‐specific?

Molecular Reproduction and Development, 2006
AbstractReproductive isolation is pivotal to maintain species separation and it can be achieved through a plethora of mechanisms. In addition, the development of barriers to gamete interaction may drive speciation. Such barriers to interspecific gamete interaction can be prezygotic or postzygotic.

Structure and species specificity

1998
The early investigators of pheromones believed that each species investigated used a unique compound for signalling purposes and, when they had isolated and identified the component found in major amount, were content to use that compound for biological investigations.

Species-specific motion detectors

Nature, 2016
A range of neuronal mechanisms can enable animals to detect the direction of visual motion. Computational models now indicate that a factor as simple as eye size might explain some of this diversity. See Article p.105 The starburst amacrine cell (SAC) dendrites of the retina play an essential role ...

“Species Specificity” of Interferons: a Misnomer?

Nature, 1967
IN 1961, there were two reports of monkey interferon protecting human cells1,2 and one of human interferon protecting monkey cells3, but in none of these was the oxtent of the cross-reaction measured. In view of the usual strict “species specificity” of iiiterferons (for example, chick interferon is not active in mouse cells, human cells4 or duck ...

Species specificity in serum albumins

Comparative Biochemistry and Physiology, 1963
Abstract 1. 1. The serum albumins of six mammalian species have been studied by methods which permit comparison of their primary structure. 2. 2. Chromatograms of the peptides produced by tryptic digestion of performate-oxidized proteins revealed patterns indicating major species differences. 3. 3.

On the Origin of Species Specificity of Fibronectin. Immunological Identification of a Species-Specific Domain of Human Fibronectin1

The Journal of Biochemistry, 1986
We have investigated whether species-specific epitopes of human fibronectin are localized at a specific domain of fibronectin using rabbit polyclonal antibodies. Tryptic fragments of human fibronectin were tested for reactivity with anti-human fibronectin antibody, which had been previously absorbed with other animal fibronectin to establish species ...
