Efficiency of Target Larvicides Is Conditioned by ABC-Mediated Transport in the Zoonotic Nematode Anisakis pegreffii
2018
Anisakiasis is among the most significant emerging foodborne parasitoses contracted through consumption of thermally unprocessed seafood harboring infective Anisakis species larvae. The efficacy of the currently applied anthelminthic therapy in humans and in model organisms has not proven sufficient, so alternative solutions employing natural compounds combined with chemical inhibitors should be explored. By testing toxicity of the natural monoterpenes nerolidol and farnesol and the conventional anthelminthics abamectin and levamisole in the presence/absence of MK-571 and Valspodar, which inhibit the ABC transporter proteins multidrug resistance protein (MRP-like) and P-glycoprotein (P-gp),…
Modulation of 5-fluorouracil as adjuvant systemic chemotherapy in colorectal cancer: the IGCS-COL multicentre, randomised, phase III study
2005
The aims of this multicentre, randomised phase III trial were to evaluate: (1) the role of levamisol (LEV); and (2) the role of folinic acid (FA), added to 5-fluorouracil (5FU) in the adjuvant treatment of colorectal cancer. Patients with histologically proven, radically resected stage II or III colon or rectal cancer were eligible. The study had a 2x2 factorial design with four treatment arms: (a) 5FU alone, (b) 5FU+LEV, (c) 5FU+FA, (d) 5FU+LEV+FA, and two planned comparisons, testing the role of LEV and of FA, respectively. From March 1991, to September 1998, 1327 patients were randomised. None of the two comparisons resulted in a significant disease-free (DFS) or overall (OAS) survival a…
Determination of levamisole hydrochloride with HgI(2-)4 by a turbidimetric method and flow-injection analysis.
1986
Abstract This paper is concerned with the use of ion-association compounds in the analysis of pharmaceutical samples by FIA. The usual extraction into an organic phase is avoided by using turbidimetric detection. Determination of levamisole with HgI2−4 has been developed as a practical example: the experimental variables were optimized by the modified simplex method. The calibration graph is linear over the levamisole concentration range 7–32 μ g ml . The reproducibility (rsd) and injection sample rate are 0.9% and 80/hr, respectively.

Specific TP53 and/or Ki-ras mutations as independent predictors of clinical outcome in sporadic colorectal adenocarcinomas: results of a 5-year Grupp…
2005
BACKGROUND: Although Ki-ras and TP53 mutations have probably been the genetic abnormalities most exhaustively implicated and studied in colorectal cancer (CRC) progression, their significance in terms of disease relapse and overall survival has not yet clearly been established. PATIENTS AND METHODS: A prospective study was carried out on paired tumor and normal colon tissue samples from a consecutive series of 160 previously-untreated patients, undergoing resective surgery for primary operable sporadic CRC. Mutations within the TP53 (exons 5-8) and Ki-ras (exon 2) genes were detected by PCR-SSCP analyses following sequencing. RESULTS: Mutation analyses of exons 5 to 8 of the TP53 gene showe…
