BACKGROUND To compare the results of external beam radiotherapy in combination with 3D- computed tomography (CT)-implanted interstitial high dose rate brachytherapy (ERT/3D-HDR-BT) versus conventional external beam radiotherapy (ERT) for the treatment of stage T2b nasopharyngeal carcinoma (NPC). METHODS Forty NPC patients diagnosed with stage T2b NPC were treated with ERT/3D-HDR-BT under loca...

It is often argued that learning from best examples in the neighbouring Burkina Faso and elsewhere, Ghana can succeed in revamping the collapsing cotton industry by introducing Bt cotton to farmers. This paper therefore presents a survey findings on farmers’ views and perceptions towards the possible introduction of Bt cotton. A stratified random sampling techniques was applied in selecting 254...

CONTEXT Adolescent obesity is becoming a national public health problem. Weight-loss medications including sibutramine facilitate weight control in adults and could be used with obese adolescents in combination with behavior therapy (BT). OBJECTIVE To examine whether increased weight loss in obese adolescents is induced when sibutramine is added to a family-based, behavioral weight control pr...

Genetic modifications of trees may provide many benefits, e.g. increase production, and mitigate climate change and herbivore impacts on forests. However, genetic modifications sometimes result in unintended effects on innate traits involved in plant-herbivore interactions. The importance of intentional changes in plant defence relative to unintentional changes and the natural variation among c...

Twelve local B. thuringiensis strains are used in the study, which previously isolated from the soil of seven governorates and characterized by their high toxicity against 2 instars larvae of cotton nd leafworm (Spodoptera littoralis). The PCR amplification analysis of the 12 Bt isolates revealed the presence of amplified fragments characteristic of five different cry genes. Results showed the ...

PURPOSE The BT-40 low-grade childhood astrocytoma xenograft model expresses mutated BRAF(V600E) and is highly sensitive to the MEK inhibitor selumetinib (AZD6244). In this study, we developed and characterized selumetinib resistance and explored approaches to circumventing the mechanisms of acquired resistance. EXPERIMENTAL DESIGN BT-40 xenografts were selected in vivo for selumetinib resista...

Non-target organisms associated with the soil might be adversely affected by exposure to the CrylAb protein from Bacillus thuringiensis (Bt) in transgenic corn (Zea mays L.). To check for such exposure, we used ELISA to test for Cry1Ab in ground beetles collected live from fields with Bt corn residues and Bt corn (Bt/Bt), Bt corn residues and non-Bt crops (Bt/non-Bt), or non-Bt corn residues an...

bacillus thuringiensis (bt) has been extensively used in biopesticidal formulations due to its safe environmental and human health records. the widespread use of bt is often challenged by production as well as formulation costs which are in direct contact with downstream processing, i.e. the separation/purification step. downstream separation/purification efficacy governs the marketability of a...
