Expanded mouse blastocysts incubated with 1 to 2 microM methylmercury (MeHg) in modified Eagle's basal medium (BME + AA), which contains amino acids, collapsed and degenerated within 24 h. In contrast, blastocysts incubated with the same concentration of MeHg in egg culture medium (ECM), which does

BACKGROUND Previous results have shown that in rats with non-ascitic cirrhosis there is an altered transport of sugars and amino acids associated with elongated microvilli. These alterations returned to normal with the administration of Insulin-Like Growth Factor-I (IGF-I). The aims of this study

Beta-N-oxalyl-L-alpha-beta-diaminopropionic acid (beta-L-ODAP) is an unusual amino acid present in seeds of plants from the Lathyrus genus that is generally accepted as the causative agent underlying the motor neuron degeneration and spastic paraparesis in human neurolathyrism. Much of the

Out of 185 media formulated and studied for the growth of Sphaerophorus necrophorus, ten were selected for intensive investigation. Their ability to promote growth was compared photometrically. Medium 156 made up of Brewer's thioglycollate broth, yeast extract, L-cystine, and ascorbic acid, was

Defolliculated Xenopus laevis oocytes were injected with size-fractionated poly(A)+ RNA (RNA) isolated from the jejunal epithelium of growing pigs (average BW 33.8 kg) to identify proteins capable of Na+ -independent amino acid transport. The ability of oocytes to absorb L-lysine (lysine) or

Young rats were used in bioassays designed to assess the protein quality and tryptophan as well as cystine adequacy of the enteral product TwoCal-HN that was either freshly prepared or had been stored (nonrefrigerated) in a warehouse for 10 mo (i.e., beyond shelf life). Based upon supplementation

Chicks fed a semisynthetic basal diet deficient in selenium and vitamin E for 14 to 22 days developed skeletal myodegeneration and exudative diathesis. Chicks fed the basal diet supplemented with either 0.2 ppm of selenium (as selenite) or 100 IU alpha-tocopherol acetate/kg were protected from

Cystine lyase is the enzyme responsible for off-aroma deterioration in fresh unblanched broccoli. In this research, cystine lyase purification from broccoli has been optimized. Only one protein peak with cystine lyase activity was found during purification. Broccoli cystine lyase was purified

Experimental dietary hepatic injury (diffuse or focal necrosis and cirrhosis in rats, with or without ascites and pleural and pericardial effusion) is determined by the dietary factors instrumental also in the production of fat infiltration of the liver and thus opposed to the lipotropic activity of
