“Its active ingredient is cysteamine, the same as in Cystagon.”

“Supplementation with cysteamine during maturation and embryo culture on embryo development of prepubertal goat oocytes selected by the brilliant cresyl blue test.”

“As long as the supply of methionine is adequate, cysteine is considered as nonessential.”

“Moreover, inhibition of the cysteine protease activity by chemical inhibitors suppressed the leaf senescence process.”

“Instead, the seed cysteine concentrations were consistently slightly lower for the transgenic seed flour than for the non-transgenic controls.”

“However, cystine crystals in the cornea are not usually detectable in the first year.”

“In 1812, William Hyde Wollaston found a substance in urine that he identified as a cystic oxide, and was later named cystine.”

“The proteins of soyabean yields all essential amino acids in adequate amounts, except methionine and cystine.”

“Methylmalonate levels were associated with poorer episodic memory and perceptual speed, and cystathionine and 2-methylcitrate with poorer episodic and semantic memory.”

“Cystathionine beta-synthase or thermolabile methylenetetrahydrofolate reductase enzymes, and vitamins like B12, B6 and folic acid are the cofactors in the metabolism of Hcy.”

“In one of these, cystinosis, there is progressive impairment in renal function.”

“While many medicines are unpleasant to take, the existing drug for cystinosis — Cystagon, from Mylan Inc. — literally stinks.”

“But in reality Cian, five, and two-year-old Ailbhe both suffer from cystinosis, a rare and potentially fatal genetic disorder.”

“Stadthagen and Brieger have also found, in a case of cystinuria diamines, chiefly pentamethylenediamine.”

“Scientists at Bethesda, Maryland, recently located a gene responsible for cystinuria, a common hereditary cause of kidney stones worldwide.”

“A urinary screen for cystine, if the diagnosis of cystinuria is not excluded by stone analysis, should be considered.”
