Torque Teno virus (TTV) is a transfusion transmitted virus that seems to be involved in several complications such as acute respiratory diseases, liver diseases, AIDS, cancer, and autoimmune reactions.  In the present study the frequency of TTV was investigated among β- thalassemia (BT) and haemodialysis (HD) patients (high risk patients for TTV) in Mazandaran province, Iran. DNA was ...

We determined whether plant volatiles help explain why Cotesia chilonis (a parasitoid of the target pest Chilo suppressalis) is less abundant in Bt than in non-Bt rice fields. Olfactometer studies revealed that C. chilonis females responded similarly to undamaged Bt and non-Bt rice plants. Parasitoids preferred rice plants damaged by 3(rd)-instar larvae of C. suppressalis, but did not different...

A 2-yr field experiment was conducted to determine the effects on Diabrotica spp. (Coleoptera: Chrysomelidae) of an insecticidal seed treatment (Poncho 1250, (AI)/clothianidin) and a granular insecticide (Aztec 2.1G, (AI)/tebupirimphos and cyfluthrin) alone and in combination with maize producing the insectidical toxin Cry3Bb1 derived from the bacterium Bacillus thuringiensis (Bt). Yields for B...

Transgenic crops producing insecticidal toxins from Bacillus thuringiensis (Bt) are widely used to control pests, but their benefits will be lost if pests evolve resistance. The mandated high-dose/refuge strategy for delaying pest resistance requires planting refuges of toxin-free crops near Bt crops to promote survival of susceptible pests. We report that pollen-mediated gene flow up to 31 m f...

Background/Aim: To compare five radiotherapy methods for prostate cancer. Patients and Methods: During 2005-2018, the data of patients with non-metastatic cancer were retrospectively analysed. treated high-dose-rate brachytherapy (HDR-BT); low-dose-rate (LDR-BT); or external-beam (EBRT), including conventionally fractionated (CFRT), moderate-hypofractionated (MHRT), ultra-hypofractionated (UHRT...

In contrast to other transgenic Bacillus thuringiensis (Bt) crops (e.g. Bt maize and cotton), risk assessments of Bt rice on soil ecosystem are few. To assess the influence of Bt rice on rhizosphere soil ecosystems, soil samples from Bt, non-Bt and controls were taken at seedling, tillering, booting, heading and maturing stages. The activities of dehydrogenases, invertase, phenol oxidases, acid...

Increased temperature anomaly during the twenty-first century coincides with the proliferation of transgenic crops containing the bacterium Bacillus thuringiensis (Berliner) (Bt) to express insecticidal Cry proteins. Increasing temperatures profoundly affect insect life histories and agricultural pest management. However, the implications of climate change on Bt crop-pest interactions and insec...

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 marketabi...

Survival and fecundity of Colorado potato beetle adults, Leptinotarsa decemlineata (Say), that had or had not fed previously on non-transgenic potato before exposure to transgenic potato containing the Bacillus thuringiensis subsp. tenebrionis Cry3A toxin (Bt) was investigated. In the laboratory, < 5% of first-generation adults survived after two weeks when restricted to Bt foliage since eclosi...
