The bioactivities of destruxins against whitefly, Bemisia tabaci and its natural enemy, ladybird beetle Serangium japonicum were evaluated. Destruxins A and B (DA and DB) showed insignificant ovicidal, oviposition deterrent and systemic insecticidal activities to B. tabaci; however, DA and DB had certain contact virulence to its nymphs. The LC(50) values of DA at 120h to 2nd, 3rd and 4th instar...
PROBLEM STATEMENT: The development of a potent vaccine that can help treat tumors resistant to conventional cytotoxic therapies remains elusive. While part of the problem may be that trials have focused on patients with bulky residual disease, the desire to maximize responses to the vaccine remains. APPROACH: The gamma(c) family of cytokines offer a unique opportunity to support the expansion ...
Response of Mungbean to the Residual Toxicity of Herbicides Used in Wheat under Strip Tillage System
Essential oils from the leaves of two species of the genus Ocotea that occur in the Atlantic Forest in the state of Pernambuco, Brazil, were analyzed using gas chromatography-mass spectrometry. The acaricidal activity of these oils as well as 11 selected components and blends were evaluated in fumigation and residual contact tests against the two-spotted spider mite (Tetranychus urticae). Sixty...
Some studies show the uptake of disinfectants on medical devices but no studies on their cytotoxicity have been reported. This study aimed to assess that cytotoxicity in a 3-dimensional culture system using HeLa cells grown in matrices composed of collagen. Plastic materials were soaked in the use solutions of the widely used high-level disinfectants, glutaraldehyde (GA), ortho-phthalaldehyde (...
8 Flax pulp was bleached by using an enzyme treatment with laccase (L stage) in the presence of HBT as 9 mediator in order to replace chlorine-based pulp bleaching processes which produce toxic organochlorine 10 compounds with biotechnological products, achieving an environmentally friendly process technology. 11 Enzyme treatments were sequentially conducted according to a factorial design invo...
BACKGROUND The efficacy and tolerability of the regimen containing paclitaxel and cisplatin (TP) in the neo-adjuvant treatment of locally advanced squamous cell cervical cancer are unknown. The TIP regimen (TP plus ifosfamide) showed high efficacy but high toxicity and it is used as an internal control. PATIENTS AND METHODS In all, 154 patients were randomized to TP (paclitaxel 175 mg/m(2) + ...
Building on the prior work of use of pentostatin in chronic lymphocytic leukemia (CLL), we initiated a trial of combined pentostatin (2 mg/m2), cyclophosphamide (600 mg/m2), and rituximab (375 mg/m2) for 65 symptomatic, previously untreated patients. Of 64 evaluable patients, 34 (53%) were high Rai risk, 71% were nonmutated for the immunoglobulin heavy-chain variable region gene, 34% were CD38+...
