HOST-MEDIATED INDUCTION OF alpha-AMYLASES BY LARVAE OF THE MEXICAN BEAN WEEVIL Zabrotes subfasciatus (COLEOPTERA: CHRYSOMELIDAE: BRUCHINAE) IS IRREVERSIBLE AND OBSERVED FROM THE INITIATION OF THE FEEDING PERIOD
(WILEY-BLACKWELL, 2010)
Larvae of Zabrotes subfasciatus secrete alpha-amylases that are insensitive to the alpha-amylase inhibitor found in seeds of Phaseolus vulgaris. By analyzing amylase activities during larval development on P. vulgaris, we ...
Adsorption of Pb(2+), Cu(2+) and Cd(2+) in FDU-1 silica and FDU-1 silica modified with humic acid
(ELSEVIER SCIENCE BV, 2008)
Ordered mesoporous silica with cubic structure, type FDU-1, was synthesized under strong acid media using B-50-6600 poly(ethylene oxide)-poly(butilene oxide)-poly(ethylene oxide) triblock copolymer (EO(39)BO(47)EO(39)) and ...
Differences in the early biomechanical effects of hyperopic and myopic laser in situ keratomileusis
(ELSEVIER SCIENCE INC, 2010)
PURPOSE: To compare changes in corneal hysteresis (CH) and the corneal resistance factor (CRF) in myopic and hyperopic laser in situ keratomileusis (LASIK) and evaluate their relationship to the number of photoablative ...

Background and objective: Pleurodesis is one of the best methods of controlling malignant pleural effusions (MPE), a distressing complication of metastatic disease. In recent studies of a wide range of pleural diseases, ...
PIXE analysis of chromium phytoaccumulation by the aquatic macrophytes Eicchornia crassipes
(ELSEVIER SCIENCE BV, 2009)
The uptake of hexavalent chromium in free living floating aquatic macrophytes Eicchornia crassipes cultivated in non-toxic chromium-doped hydroponic solutions is presented. A Cr-uptake bioaccumulation experiment was carried ...
Histological analyses of thermal effect caused by 1.2 W diode laser irradiation at rat periodontal pockets
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009)
The aim of this in vivo study was to evaluate the thermal effects caused by 810 nm 1.2 W diode laser irradiation of periodontal tissues. Despite all data available concerning the laser application for periodontal treatment, ...
