Genetic diversity of Trypanosoma cruzi may play a role in pathogenesis of Chagas disease forms. Natural populations are classified into 6 Discrete Typing Units (DTUs) Tc I-VI with taxonomical status. This study aimed to identify T. cruzi DTUs in bloodstream and tissue samples of Argentinean patients with Chagas disease. PCR-based strategies allowed DTU(More)
Alanine aminopeptidase (AAP), carcinoembryonic antigen (CEA), and tissue polypeptide antigen (TPA) were measured in 40 patients with breast and thyroid cancer and in 40 patients suffering from benign tumors and benign noninflammatory diseases. AAP activity was significantly increased (P < 0.001) in all cancer patients considered together. TPA shows a(More)
The influence of uremic middle molecules on in vitro lymphocyte blast transformation and interleukin-2 production was studied in 12 patients on long-term hemodialysis and 12 healthy control subjects with normal kidney function. Middle molecules inhibit phytohemoagglutinin induced lymphocyte proliferation in a concentration dependent fashion, achieving more(More)
N-acetyl-beta-glucosaminidase (NAG) and its isoenzymes were measured in 60 patients with breast cancer and in 30 patients suffering from benign breast tumors. NAG activity was significantly increased (P < 0.001) in cancer patients. The concentration of isoenzyme A always exceeded that of isoenzyme B, but isoenzyme B concentration was significantly (p <(More)
We have developed a high-performance liquid chromatographic-UV-Vis-diode-array detection (HPLC-DAD) method for the determination of ethyl-p-hydroxybenzoate, a hydrolytic degradation product of the synthetic protease inhibitor, gabexate-mesilate ethyl-p-(6-guanidinohexanoyloxy) benzoate methanesulfonate (GM) (FOY) in sow pancreatic juice.(More)
We used a liquid-chromatographic method to measure xanthine, hypoxanthine, and inosine in plasma of uremic patients before and after hemodialysis. The concentrations of all three were higher than in normal subjects. After dialysis treatment, the values were significantly lower than before dialysis, but still above normal.
Forty patients with advanced transitional cell cancer (TCC) of the bladder were treated with cisplatin, epirubicin, methotrexate (PEM, every 3-4 weeks). If creatinine clearance was reduced to 40 ml/min, the usual full doses of cisplatin and methotrexate, 50 mg/m2, were proportionally reduced. 23 patients had full-dose (FD) therapy, 17 had reduced dose (RD)(More)
N-Acetyl-β-glucosaminidase (NAG) and β-glucuronidase were measured in the serum of 70 patients with breast and digestive-tract neoplasms and in 70 healthy subjects. The mean value of the NAG activity was significantly (P<0.001) elevated in patients with gastric, liver and pancreas cancer as compared with the reference population. In patients with liver and(More)
