Ruminants have high concentrations of peptide-bound amino acids in the circulation. Earlier studies in our laboratory showed that a myogenic cell line (C2C12) developed from mouse skeletal muscle and a mammary epithelial cell line (MAC-T) developed from bovine mammary epithelial tissues are able to utilize peptides as amino acid sources. In this study, primary cultures of ovine myogenic satelli...

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an indigenous grain legume. It occupies a prominent place in the strategies to ensure food security in sub-Saharan Africa. Development of an efficient in vitro regeneration system, a prerequisite for genetic transformation application, requires the establishment of optimal conditions for seeds germination and plantlets development. Three type...

Hatch, M. H. (Brown University, Providence, R.I.) and C. A. Stuart. Urease activity of Proteus species in filtered compared with autoclaved urea media. J. Bacteriol. 83:1119-1123. 1962.-Urease activity of a number of strains of four Proteus species was compared in a filtered medium and an autoclaved medium. Various amounts of saline suspensions of the organisms were used as inocula for the two ...

Introduction. Central cholinergic neurons are reported to be important in memory acquisition and are known to degenerate in Alzheimer's disease.l) Since nerve growth factor (NGF) was found to increase choline acetyltransf erase (ChAT) activity''),.) and prevent cholinergic neuron death,4)-°~ investigators started to look for other neurotrophic factors for these neurons. So far, fibroblast growt...

Efficient procedures are outlined for plant regeneration through direct shoot bud formation and indirect organogenesis through callus formation in Ornithogalum virens Lindl using bulb scale as explant. Murashige and Skoog’s (MS) medium containing 1 mg/L (5.4mM) NAA and 2 mg/L (4.4mM) BA was most effective in direct induction of shoot buds from explant. Callus cultures were raised from the bulb ...

The production of beta-galactosidase by Sf9 cells infected with recombinant Autographa californica nucleopolyhedrovirus (AcNPV) was investigated in shake-flask culture using two serum-free basal media: Grace's medium and TNM-FH (Grace's medium supplemented with lactalbumin hydrolysate and yeast extract). At the time of infection, cells grown in serum-supplemented TNM-FH were transferred into fr...
