guanine/vomiting

A 39-year-old man with myotonic dystrophy consulted our hospital for nausea, vomiting and dizziness that occurred after 75 g oral glucose tolerance test (OGTT). Reexamination of OGTT revealed remarkable hyperinsulinemia (622 microU/ml) followed by reactive hypoglycemia (50 mg/dl) and such

Two Korean siblings with partial hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency are reported. The index patient was a boy aged 9 years 10 months who developed acute renal failure with a serum uric acid level of 25.9 mg/dl, after vomiting. The younger brother was asymptomatic but

Rationale: Lesch-Nyhan syndrome (LNS) is an X-linked recessive disorder presenting with uric acid overproduction, neurocognitive disability, and behavioral disturbances. Inhalational anesthesia has been frequently used in LNS patients

Introduction. Cerebral venous sinus thrombosis (CVST) is a rare form of cerebrovascular disease, which may manifest clinically by a wide variety of signs and symptoms. It has been associated with multiple risk factors including genetic or acquired blood disorders, infections, and trauma. Case

OBJECTIVE Temozolomide (TMZ) is an oral alkylating agent that produces methyl adducts at the 0.6 position of guanine. The methyl adducts are removed by the DNA repair enzyme AGAT. As demonstrated by in vitro studies, cisplatin (CDDP) is able to down-regulate the AGAT activity, suggesting that CDDP

Norovirus is an acute infection of the gastrointestinal tract causing rapid induction of vomiting and diarrhoea. The infection is sensed and controlled by the innate immune system, particularly by the RNA helicase MDA-5 and type I and III interferons (IFNs). We have observed that intracellular

BACKGROUND The majority of women with epithelial ovarian cancer present with advanced stage disease and there is a critical need for novel drugs and treatment strategies to improve outcomes. Trabectedin is a unique cytotoxic agent with a complex mechanism of action. It binds to guanines in the N2

BACKGROUND There is pre-clinical evidence of synergism between cisplatin and temozolomide due to higher inhibition of O(6)-alkyl-guanine-alkyltransferase (AGAT), an enzyme involved in the mismatch repair system and in the mechanisms of drug resistance to alkylating agents. METHODS Heavily

BACKGROUND Over the years, acyclovir has been the oral antiviral agent approved for the treatment of patients with acute herpes zoster,Its effectiveness in lessening the acute signs and symptoms of herpes zoster has been established but the effects on post herpetic neuralgia are less clear cut.

BACKGROUND PM00104 binds guanines at DNA minor grooves, impacting DNA replication and transcription. A phase I study was undertaken to investigate safety, dose-limiting toxicities (DLTs), recommended phase II dose (RP2D), pharmacokinetics (PKs) and preliminary antitumour activity of PM00104 as a 1-

Temozolomide (TMZ) is an oral imidazotetrazinone that is spontaneously converted to 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC) at physiological pH. MTIC methylates DNA at the O6 position of guanine, although this lesion may be repaired by the enzyme O6-alkylguanine-DNA alkyltransferase

Tiazofurin (2-B-D-Ribofuranosylthiazole-4-Carboxamide: NSC 286193) is a nucleoside antimetabolite that acts as a potent inhibitor of IMP dehydrogenase resulting in a guanine nucleotide deprivation. Recent in vivo biochemical observations in rats bearing hepatoma suggested a correlation between

OBJECTIVE O(6)-methylguanine-DNA-methyltransferase (MGMT) is a DNA repair protein removing mutagenic and cytotoxic adducts from O(6)-guanine in DNA. Approximately 40% of colorectal cancers (CRC) display MGMT deficiency due to the promoter hypermethylation leading to silencing of the gene. Alkylating

OBJECTIVE This Phase I study was designed to determine the maximum tolerated dose, profile of adverse events, and dose-limiting toxicity of AP5280 in patients with solid tumors. Furthermore, the platinum (Pt) pharmacokinetics after AP5280 administration and preliminary antitumor activity were
