Properties of carbohydrate utilising variants of Chinese hamster cells. | Variants of Chinese hamster ovary cells (CHO-K1) have been isolated which can grow on one of the following carbohydrates: lactose, sucrose, ribose or lactate. The ribose+ clones grow at the same rate on glucose as the parental cells whereas the others grow more slowly. With the exception of one ribose+ clone all excret... | 610,885 | [

[Melanocytes in epiloia; ultrastructural aspects (about 7 cases) (author's transl)]. | Hypopigmented macules of epiloia have been studied by photonic and electron microscopy in 7 cases. The number of melanocytes was not decreased but these cells were hypotrophic and had a low tyrosinae activity. The melanosomes were smaller in size and their maturation rate was greatly reduced; many abnormal round and gr... | 613,951 | [

Effects of maleic acid administration on urinary excretion of DCEC, and on tissue protein, in the rat. | Administration of maleic acid to rats caused increased urinary excretion of S-(1,2-dicarboxyethyl)cysteine [DCEC] and increased binding of maleic acid to tissue proteins. The trichloroacetic acid precipitate from a combined fraction of supernatant and microsome gave the maximum amount of DCEC after hydrolysis. It would... | 614,593 | [
