cystine/fever

Our previous findings [Hazelton & Lang (1978) Fed. Proc. Fed. Am. Soc. Exp. Biol. 37(6), 2378 (abstr.)] demonstrated a senescence-specific decrease in glutathione (GSH) concentration in the yellow-fever mosquito Aedes aegypti (Louisville)]. As a possible mechanism for this change, GSH biosynthesis

Chinese hamster ovary (CHO) cells cultured in vitro were continuously exposed to increasing concentrations of diethylmaleate (DEM). Chronic exposure of these cells (designated CHO/DEM) to 80 microM diethylmaleate resulted in an increase in cystine transport, a decrease in glutathione inhibition of

We recently found that exposure of cells to different aminothiols promotes cystine uptake and leads to an increase of cellular glutathione by new biosynthesis (Issels et al., Biochem. Pharmacol., 37: 881-888, 1988). Therefore, we further investigated whether the known radioprotective and

Cystinosis, a rare autosomal recessive lysosomal storage disease, can be difficult to detect. The most common form of the disease is infantile or nephropathic cystinosis. Crystals can accumulate in the eye as early as 1 year of age. Early recognition and prompt investigations prevent further

Thirty patients (16 men and 14 women) with cystine urinary stones were treated by extracorporeal shock wave lithotripsy (Dormer HM-3) from December 1984 through October 1989. The average patient age was 35.2 years with a range of 14 to 59 years. Seventy per cent of these subjects had had previous

A 2-year old boy visited our clinic with a chief complaint of high fever. A past history of acute renal failure due to cystine stones and cystinuria was expressed. Abdominal rentogenograms and CT demonstrated a right ureteral stone and a left renal stone. Furthermore renogram evaluation indicated

Background: There are limited data about urolithiasis in young infants, especially in class age younger than 2 years. Case presentation: We report the case of a child <2 years old (13 months) affected by metabolic urolithiasis (cystinuria), and renal hypertension. He

OBJECTIVE To investigate the efficacy and safety of retrograde intrarenal surgery (RIRS) in the treatment of pediatric cystine stones. METHODS Data of the pediatric patients who underwent RIRS for kidney stones were retrospectively evaluated. A total of 14 children with cystine stones managed with

Cultures of blood from patients with rheumatism during the active and inactive phases of the disease, treated and untreated with antibiotics were studied. The following results were obtained in blood cultures (on Klodnisky's medium with a 0.01% cystine) of 105 patients with rheumatism: L-forms of

Streptococcal toxic shock syndrome (STSS) is a highly lethal, acute-onset illness that is a subset of invasive streptococcal disease. The majority of clinical STSS cases have been associated with the pyrogenic toxin superantigens (PTSAgs) streptococcal pyrogenic exotoxin A or C (SPE A or C),

We recently reported the isolation of a scorpion toxin named U1-liotoxin-Lw1a (U1-LITX-Lw1a) that adopts an unusual 3D fold termed the disulfide-directed hairpin (DDH) motif, which is the proposed evolutionary structural precursor of the three-disulfide-containing inhibitor cystine knot (ICK) motif

A five-year-old boy was referred to our pediatric clinic for evaluation of failure to thrive, headache, intermittent high fever, restlessness, polyuria, and polydipsia. His weight and height measurements were under the 3rd percentile. Clinical findings consisted of frontal bossing, carious teeth,

Chinese hamster ovary cells were exposed to the sulfhydryl compound cysteamine at different temperatures (5 degrees C, 37 degrees C, 44 degrees C) at concentrations known to generate activated oxygen species. At 37 degrees C, the cellular glutathione (GSH) content increased linearly over the time of

Although a significant decrease has been reported in the incidence of diphteria in many regions of the world following the routine diphtheria immunization programs, the emergence of new cases indicated that toxigenic strains are still circulating in the community. Diphtheria vaccine does not provide

Tularemia which is a multisystem disease of humans and some animals, is endemic in North America, some parts of Europe and Asia. The causative agent, Francisella tularensis, is a fastidious gram-negative, intracellular bacterium which requires supplementation with sulphydryl compounds (cysteine,
