Since the introduction of insect-resistant crops in 1996, cultivation of this group of genetically modified crops has grown substantially. There are many Bt corn events in field trials, but only one is commercialized on the Romanian market. The levels of the protein in plant tissue would be valuable in determining the protein concentration to which(More)
Die Autoren beschreiben eine neue Methode der Suspensionskultur von Zellen. Sie beruht darauf, daß die Adhäsion der Zellen durch Benützung eines nicht-haftenden Agarsubstrats verhindert wird. Die nicht-haftenden Zellen aggregieren sich in Suspension. Morphologische Untersuchungen der Zellinseln zeigten Lebensfähigkeit und Proliferation. Es wird angenommen,(More)
After the resection of methylcholanthrene-induced fibrosarcomas, representing 1--2% of total body weight, "R" rats were immunized with glutaraldehyde-fixed tumor cells, irradiated sublethally [0.1419 C kg-1 (550 R)], and restored immunologically by thymus, spleen and bone marrow cells. Afterwards, 87.5% of them were able to reject a viable challenge cell(More)
The humoral and cellular immune status of C57BL/6 male mice and "R" male rats bearing MC-induced sarcomas were investigated in vitro, using 51Cr-releasing and mixed hemadsorption assays. Analysis was performed on mice subjected to concomitant tumor immunity (CTI) model experiments or bearing primary tumors of different sizes, that was done also in rats.(More)
masticatory and neck muscles in asymptomatic (Ceneviz et al 2006; Miralles et al 2002) and symptomatic subjects (Santander et al 1994; Miralles et al 1992), showing that temporary changes in the mandible position influences the craniocervical system. Electromyography (EMG) is performed to investigate the electrical activity of the muscles affected by CD for(More)
Concomitant tumor immunity evinced by C57BL/6 mice, bearing a MC-induced sarcoma, was evaluated by graded challenge doses for different primary tumor sizes (2-3,4-6,8-12% tumor weight of the total body weight TW/TBW). 100% of mice bearing tumors, representing 2--6% of total body weight, rejected doses from 0.2--1 X 10(4) cells. The gradual curtailment of(More)
Agriculture faces many challenges to maximize yields while it is required to operate in an environmentally sustainable manner. In the present study, we analyze the major agricultural challenges identified by European farmers (primarily related to biotic stresses) in 13 countries, namely Belgium, Bulgaria, the Czech Republic, France, Germany, Hungary, Italy,(More)
