BACKGROUND Inasmuch as endovascular brachytherapy (BT) has gained recent interest because of its inhibitory effect on mechanisms leading to restenosis after percutaneous transluminal angioplasty (PTA), we performed this randomized study to determine its efficacy for prophylaxis of restenosis after femoropopliteal PTA. METHODS AND RESULTS One hundred thirteen patients (63 men, 50 women; mean a...

Evolution of resistance by pests is the main threat to long-term insect control by transgenic crops that produce Bacillus thuringiensis (Bt) toxins. Because inheritance of resistance to the Bt toxins in transgenic crops is typically recessive, DNA-based screening for resistance alleles in heterozygotes is potentially much more efficient than detection of resistant homozygotes with bioassays. Su...

Pulsed dose rate (PDR-BT) treatment is a brachytherapy modality that combines physical advantages of high-dose-rate (HDR-BT) technology (isodose optimization, radiation safety) with the radiobiological advantages of low-dose-rate (LDR-BT) brachytherapy. Pulsed brachytherapy consists of using stronger radiation source than for LDR-BT and producing series of short exposures of 10 to 30 minutes in...

Genes of Bacillus thuringiensis var. kurstaki (Berliner) that encode lepidopteran-specific toxins were engineered into maize for protection against the European Corn Borer, Ostrinia nubilalis (Hbn.). Recent data suggest that Lepidoptera may be negatively affected, if maize pollen contains high amounts of Bt toxin and is diposited on host plants near maize fields. Monitoring the environmental ef...

Objective: To assess the cost-efficacy of three fixed-combination glaucoma treatments currently available in Spain [bimatoprost with timolol (BT)Ganfort®, latanoprost with timolol (LT) Xalacom®, and travoprost with timolol (TT) DuoTrav®]. Methods: Because no studies are available that give a direct comparison of these drugs, a systematic review was carried out to assess their efficacy. Resource...

Genetically engineered crops represent one of the most controversial and rapidly adopted technologies in the history of agriculture. To improve pest control, scientists have engineered cotton, corn, and soybeans to make insecticidal proteins from the common bacterium Bacillus thuringiensis (Bt) [1]. These Bt toxins kill some devastating pests, but unlike broad-spectrum insecticides, they do lit...

PURPOSE Ocular blood flow dysregulation has been implicated in the pathogenesis of glaucoma. Whereas the effect of single antiglaucoma substances on ocular blood flow has been addressed in various experiments, evidence for fixed combinations is sparse. In the present study, we set out to compare the effects of latanoprost 0.005%/timolol 0.5% (LT) fixed combination and brimonidine 0.2%/timolol 0...

The present paper deals with study of In-vitro cytotoxicity effect of isolated gossypol from Bt and Non-Bt cotton seeds on HeLa cell lines. Gossypol is a polyphenolic binaphthyl diadehyde natural yellow colored pigment. It is not only resistance substance for cotton plant’s self – defense system against insect pests and possibly some diseases but also an important phytochemical compound of imme...

Bloom’s Taxonomy (BT) is widely used in educational institutions to produce high-quality exam papers evaluate students’ knowledge at different cognitive levels. However, manual question labeling takes a long time, and not all evaluators are familiar with BT. The researchers worked automate the classification process based on BT as solution. Enhancement term weighting one of ways increase accura...
