OBJECTIVES: I. Evaluate the efficacy of oral ribose in patients with a complex 5'-nucleotidase syndrome who have not received uridine (UR) and thymidine (TDR).
II. Evaluate the efficacy of UR/oral ribose and UR/TDR. III. Evaluate the efficacy of oral ribose given in combination with UR/TDR.
PROTOCOL OUTLINE: Newly identified patients receive ribose daily for 8 weeks. Patients who improve continue therapy. If improvement then reaches a plateau, uridine (UR) and thymidine (TDR) are added to the regimen.
Patients who receive no benefit after 8 weeks of ribose are treated with UR/TDR. Patients who improve after 8 weeks of this combination continue therapy.
Ribose is added to the treatment regimen for patients on UR/TDR at entry. At maximal improvement, TDR and UR are sequentially tapered.
Primary Purpose: Treatment
ribose, thymidine, uridine

To determine whether adding Ribose 5 grams 3 x day would improve quality of life, energy, sleep and cognitive function and decrease pain in patients with CFS and/or fibromyalgia (CFS/FMS).
This is a randomized, double-blind, placebo-controlled study of the investigational drug uridine as a treatment for suicidal ideation in veterans. The investigators hypothesize that the a...
The purpose of the study is to see if the investigational medication uridine reduces depression symptoms in adolescents with bipolar disorder. Uridine is a naturally occurring chemical th...
Patients with confirmed mitochondrial DNA depletion syndrome 2 (thymidine kinase 2 [TK2] deficiency) have reduced levels of nucleotides (deoxythymidine monophosphate and deoxycytidine mono...
The purose of this research study is to determine the potential benefit of D-ribose, a nutritional supplement (a sugar), versus a placebo (another sugar) in people with fibromyalgia.
There is growing evidence that uridine may act as an endogenous neuromodulator with a potential signaling role in the central nervous system in addition to its function in pyrimidine metabolism. We pr...
Ribose-5-phosphate isomerase deficiency, a disorder of the pentose phosphate shunt, was described in 1999. There are 2 previously reported cases of ribose-5-phosphate isomerase deficiency. Here, we de...
Ribosome inactivating protein (RIP) catalyzes the cleavage of glycosidic bond formed between adenine and ribose sugar of ribosomal RNA to inactivate ribosomes. Previous structural studies have shown t...
In this study, a uridine and acetoin co-production pathway was designed and engineered in Bacillus subtilis for the first time. A positive correlation between acetoin and uridine production was observ...
Uridine is a kind of pyrimidine nucleoside that has been widely applied in the pharmaceutical industry. Although microbial fermentation is a promising method for industrial production of uridine, an e...
The enzyme catalyzing the transfer of 2-deoxy-D-ribose from thymidine to orthophosphate, thereby liberating thymidine. EC 220.127.116.11.
An enzyme that catalyzes the transfer of ribose from uridine to orthophosphate, forming uracil and ribose 1-phosphate. EC 18.104.22.168.
A group of uridine ribonucleotides in which the phosphate residues of each uridine ribonucleotide act as bridges in forming diester linkages between the ribose moieties.
An enzyme that catalyzes the conversion of ATP and thymidine to ADP and thymidine 5'-phosphate. Deoxyuridine can also act as an acceptor and dGTP as a donor. (From Enzyme Nomenclature, 1992) EC 22.214.171.124.
A ribonucleoside in which RIBOSE is linked to URACIL.
