Biochemical Medicine, 1970
Abstract 35 S- l -cystine was injected intravenously into anaesthetised dogs, and the rate of disappearance of radioactive cystine was measured. Cystine was isolated from the plasma by two different techniques before determination of the radioactivity.

Cystine calculi are radiopaque
American Journal of Roentgenology, 1980Cystine calculi are said to be either radiolucent or radiopaque. In the past, contamination of the calculi with calcium has been given as the reason for a radiopaque appearance. However, most cystine stones are pure cystine and contain essentially no calcium.

Historically, cystine stone chemolysis has been approached with 2 different categories of compounds--alkalizing agents (sodium bicarbonate and tromethamine) and, more recently, protonated thiols and disulfide compounds (alpha-mercaptopropionylglycine, N-acetylcysteine and penicillamine).

Comparative Uptake of Selenium by Low Cystine and High Cystine Proteins
Canadian Journal of Biochemistry, 1971Purified preparations of skin collagen, tendon gelatin, and thymus histones, isolated from various animals administered 75Se-labeled selenite, contained only a trace of cystine (plus [Formula: see text]-cystine) and incorporated very little 75Se activity.

Cystine Urolithiasis in Ferrets
Veterinary Clinics of North America: Exotic Animal Practice, 2020Urolithiasis in captive domestic ferrets has previously been predominantly struvite uroliths, although more recent laboratory submissions show a shift to predominantly cystine uroliths. Genetic mutations for cystinuria have been identified in dogs, and it is suspected that underlying genetic mutations are partly responsible for this disease in ferrets.

Uptake of cystine by cystine-depleted fibroblasts from patients with cystinosis
Biochemical and Biophysical Research Communications, 1981Abstract [ 35 S]L-cystine uptake was measured in cultured skin fibroblasts from patients with nephropathic cystinosis, pretreated with cysteamine to deplete their cystine pools. The uptake was greater in the cystinotic cells than in normal cells.

The Effect of Cystine Level and Urinary PH on the Recurrence of Cystine Stones
Journal of Pediatric Urology, 2009Purpose Retrospective review of the medical therapy on pediatric patients with cystin stones as regards recurrence rates. Material and Methods 21 patients (12 boy, 9 girl) under follow-up with cystin stones were retrospectively evaluated. Median diagnosis age was 1 year old(range:1-16).

Response of enteroviruses to cystine
Virology, 1961Abstract Polioviruses types 1, 2, and 3 were stabilized against heat inactivation by in vitro exposure to L-cystine, 50 μg/ml. The rate of stabilization was fastest with type 1 and slowest with type 3. Strains of the same poliotype may show different rates of stabilization.

Stabilization of poliovirus by cystine
Virology, 1958Abstract Incubation of a heat-sensitive strain of (t + ) poliovirus with l -cystine produces a considerable enhancement of its thermal stability at temperatures below 50°. The effect is specific in that d -cystine and a number of other compounds are ineffective.
