Effects of hydrogen sulfide (H(2)S) on plant physiology have been previously studied, but such studies have relied on the use of NaSH as a method for supplying H(2)S to tissues. Now new compounds which give a less severe H(2)S shock and a more prolonged exposure to H(2)S have been developed. Here the effects of one such compound, GYY4137, has been(More)
Women with polycystic ovary syndrome (PCOS) have a clustering of cardiovascular risk factors, such as obesity, lipid abnormalities, impaired glucose tolerance, insulin resistance, and hypertension. Exercise is reported to lower the incidence of cardiac events. The effect of exercise on plasma homocysteine concentrations, an independent cardiovascular risk(More)
Between January 1992 and January 1999, we treated 378 B-chronic lymphocytic leukaemia (CLL) patients with cladribine (2-CdA), and 255 of the patients were also treated with prednisone. A total of 194 patients were previously untreated, and 184 had relapsed or refractory disease after previous other therapy. Complete response (CR) was obtained in 111 (29.4%)(More)
Eosinophilia and allergic skin reactions are uncommon events after 2-chlorodoxyadenosine (2-CdA, cladribine) administration. A multicentre retrospective analysis of eosinophilia in 360 patients treated with 2-CdA for lymphoid malignancies has been made. B-cell chronic lymphocytic leukaemia (B-CLL) was diagnosed in 153, hairy cell leukaemia (HCL) in 68,(More)
BACKGROUND The reactivation of telomerase is believed to play an important role in immortalization and carcinogenesis. OBJECTIVE To investigate the expression of three components of the telomerase complex (hTR, hTERT and TP1), along with telomerase activity in malignant and normal cells. METHODS Cells were isolated from gastric and colon cancer, and(More)
GH therapy is associated with a reduction in fat mass and an increase in lean mass in subjects with GH deficiency (GHD). Leptin, like GH, plays an important role in the regulation of body composition. GH treatment has been shown to reduce serum leptin; however, the physiological interactions between the leptin system (free leptin, bound leptin, and soluble(More)
PURPOSE Little is known about comparison of the activity of different purine nucleoside analogs in chronic lymphocytic leukemia (CLL). We conducted a randomized phase III trial to compare efficacy and safety of cladribine and fludarabine, each combined with cyclophosphamide, in previously untreated progressive CLL. PATIENTS AND METHODS Patients received(More)
The purpose of our study was to determine the effectiveness of 2-CdA in 2-hour intravenous infusions in the treatment of B-CLL. One hundred and ten patients with B-CLL received 1 to 10 courses of 2-CdA (median 2.5) at a dosage of 0.12 mg/kg daily for 5 consecutive days. Eighteen of them were untreated and 92 relapsed or became refractory to previous(More)
We measured serum levels of free leptin, bound leptin, and soluble leptin receptor by specific RIA methods in 20 normal and 19 insulin-dependent diabetes mellitus subjects at 20 and 30 weeks gestation and postpartum, and analyzed the data using hierarchical statistical models. Total leptin levels rise from 20-30 weeks gestation (688 +/- 58 to 785 +/- 62(More)
BACKGROUND Retinol-binding protein-4 (RBP-4) may increase insulin resistance (IR) in animals, with elevated levels reported in humans with obesity and type 2 diabetes. There are, however, few data on concentrations of RBP-4 in gestational diabetes mellitus (GDM). METHODS We measured fasting serum levels of RBP-4, soluble intercellular adhesion molecule-1(More)
