The current difficulty facing risk evaluations of Bacillus thuringiensis (Bt) crops on nontarget arthropods (NTAs) is the lack of criteria for determining what represents unacceptable risk. In this study, we investigated the biological parameters in the laboratory and field population abundance of Nilaparvata lugens (Hemiptera: Delphacidae) on two Bt rice lines and the non-Bt parent, together w...
This paper discusses service creation tools and the benefits which these tools can deliver. The BT VISAGE (voice interactive services application generation environment) service creation tool is used as a specific example and is described in some detail. VISAGE is currently used within BT to generate advanced network-based services, an example of this being the network-based call-answering serv...
Background—Anal fissure is perpetuated by high sphincter pressures and secondary local ischaemia. Pharmacological approaches include topical nitrates and botulinum toxin (BT) which act to reduce anal pressure. BT lowers anal pressure by preventing acetylcholine release from nerve terminals while topical nitrates act by donating nitric oxide (NO). The aims of the present study were to compare th...
تنش های زیستی نظیر آفت پیله خواراز عوامل اصلی کاهش عملکرد نخود محسوب می شوند. انتقال ژن به نخود با هدف افزایش مقاومت به این آفت، از اهداف اصلاحی در این گیاه زراعی می باشد. یکی از راهبردهای موثر برای تولید نخود تراریخته مقاوم به آفت پیله خوار، استفاده از سموم طبیعی cry از باکتری باسیلوس تورینجینسیس است. این سموم قادرند در معده حشرات فعال شده و سیستم گوارشی حشره را مختل نمایند. در مطالعه ای که تو...
one of the major obstacles of bt production as a biopesticide is its expensive bioprocess and fermentation. therefore, the objective of the present study was to optimize growth condition and develop a low-cost bioprocess for mass production of a native coleopteran-effective bacillus thuringiensis (bt) strain (kh4) based on agricultural wastes, at incubator and batch fermenter level. preliminary...
Field trials were conducted from 2007 to 2010 to compare grain fumonisin levels among non-Bt maize hybrids and Bt hybrids with transgenic protection against manual infestations of European corn borer (ECB) and Western bean cutworm (WBC). HPLC and ELISA were used to measure fumonisin levels. Results of the methods were highly correlated, but ELISA estimates were higher. Bt hybrids experienced le...
RATIONALE Bronchial thermoplasty (BT) is a bronchoscopic procedure in which controlled thermal energy is applied to the airway wall to decrease smooth muscle. OBJECTIVES To evaluate the effectiveness and safety of BT versus a sham procedure in subjects with severe asthma who remain symptomatic despite treatment with high-dose inhaled corticosteroids and long-acting beta(2)-agonists. METHODS...
PURPOSE There are limited data at a population level on adjuvant brachytherapy (BT) practice for uterine corpus malignancies. The aims of the current study were to describe BT practice for this disease in New South Wales (NSW), to assess quality of BT, and to determine if a caseload effect on quality exists. MATERIAL AND METHODS Patient, tumour, and treatment related data were collected from ...
Accessible online at: www.karger.com/journals/ene Therapeutic use of botulinum toxin type A (BT-A) has dramatically increased after its introduction by Scott [1] in 1980. It now provides help for patients suffering from muscle hyperactivity disorders in neurology, rehabilitation medicine, pediatrics, otorhinolaryngology, ophthalmology, urology and many other areas. Recently, it has been recogni...
