Absfrucf.-To determine whether the embryonic period of channel catfish lcfalurus punctntus could be extended at low temperatures, fertilized channel catfish eggs were incubated at five constant water temperatures: 4, I I . 16. 21, and 26 C. Low-temperature incubation of catfish eggs extended the embryonic period at 16 (244%) and 21 C (56%) when compared to the control hatchery incubation temper...

Recent work exploring the relationship between early environmental conditions and cognition has shown that incubation environment can influence both brain anatomy and performance in simple operant tasks in young lizards. It is currently unknown how it impacts other, potentially more sophisticated, cognitive processes. Social-cognitive abilities, such as gaze following and social learning, are t...

Endogenous circulating digoxin-like immunoreactive factors (DLIF) are known to cross-react with antibodies to digoxin and to inhibit Na+/K(+)-transporting ATPase (Na+K+ATPase; EC 3.6.1.37). Moreover, increasing the immunoassay temperature from 4 to 37 degrees C markedly decreases DLIF from human cord serum. We tested several compounds, including hormonal steroids, bile salts, lipids, and methio...

we separated platelets from whole blood and incorporated them into in-ill and te-99m agents. sn-gha, tropolone, oxine (sulphate) and hmpao were used to diffuse radionuclides into the platelets. the effects of time, temperature, ph of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m c13 and te-99m on labeling efficiency were studied.

Growth in developing turbot larvae can be expressed independently of temperature when using effective day-degrees (D8 ) as an index of development. The calculation of D8 is based on the eff eff principle of thermal summation whereby the rate of development is linearly related to the ambient temperature above a species-specific threshold temperature (T ) at which development is 0 theoretically a...

The aim of current study was to test the ability and optimize decolorization textile azo Reactive Orange 122 by Streptomyces sp (A5) isolated from dye contaminated soil. isolate assessed spectrophotometer at 3, 5 7 days in starch nitrate broth media amended with 0.35 g/L dye. Different incubation conditions like concentration dye, temperature pH were used present investigate their effect on rat...
