Populations of onion thrips, Thrips tabaci Lindeman, from commercial onion Þelds in New York were evaluated for their susceptibility to the commonly used pyrethroid, -cyhalothrin (Warrior T), using a novel system called the Thrips Insecticide Bioassay System (TIBS). To use TIBS, thrips are collecteddirectly from theplant into an insecticide-treated 0.5-mlmicrocentrifuge tube that has a ßexible ...

The acute and subacute hypoglycemic and antihyperglycemic effects of drinkable ripe onion juice (Commercial product name is "Black Onion Extract") were investigated in normal and streptozotocin-induced diabetic rats. For tests of acute and subacute hypoglycemic effects, ripe onion juice (5 and 15 mL/kg b.w.) was administered by oral gavage to normal Sprague Dawley rats and measurements of fasti...

UNLABELLED A cell viability assessment method based computer vision analysis of the uptake of neutral red dye was used to quantify cell membrane integrity in raw and processed parenchyma cells of onion tissues. The presence of stained vacuoles was used as an indicator of tonoplast membrane integrity and photomicrographs were acquired for microscopic image analysis and cell integrity quantificat...

Onion Routing is an infrastructure for private communication over a public network. It provides anonymous connections that are strongly resistant to both eavesdropping and traac analysis. Onion routing's anonymous connections are bidirectional, near real-time, and can be used anywhere a TCP/IP socket connection can be used. This prospectus outlines the alpha onion routing system and deenes a re...

In the present study, invertase-mediated nanogold clusters were synthesized on onion membranes, and their application for sucrose biosensor fabrication was investigated. Transmission electron microscopy revealed free nanoparticles of various sizes (diameter ~5 to 50 nm) along with clusters of nanogold (~95 to 200 nm) on the surface of inner epidermal membranes of onions (Allium cepa L.). Most o...

Onion (Allium cepa L.) is widely consumed as food or medicinal plant due to its well-defined health benefits. The antioxidant and antihyperlipidemic effects of onion and its extracts have been reported well. However, very limited information on anti-hyperglycemic effect is available in processed onion extracts. In our previous study, we reported that Amadori rearrangement compounds (ARCs) produ...

Burkholderia cepacia complex strains are genetically related but phenotypically diverse organisms that are important opportunistic pathogens in patients with cystic fibrosis (CF,) as well as pathogens of onion and banana, colonizers of the rhizospheres of many plant species, and common inhabitants of bulk soil. Genotypic identification and pathogenicity characterization were performed on B. cep...

12 Some intervention studies have shown that quercetin supplementation can regulate certain biomarkers, 13 but it is not clear how the doses given relate to dietary quercetin (e.g. from onion). We conducted a 14 two-period, two-sequence crossover study to compare the bioavailability of quercetin when 15 administered in the form of fresh red onion meal (naturally glycosylated quercetin) or dieta...

Antibacterial in vitro activity of white (bulb), red (bulb) and spring (bulb and leafs) onion towards the Gramnegative Escherichia coli 8752 and the Gram-positive Bacillus subtilis 8751 was investigated. Mature onion samples were purchased from a big supermarket while the green onion was organically grown. Experiments were performed via agar well diffusion method. Samples were separately homoge...

Transient transformation is simpler, more efficient and economical in analyzing protein subcellular localization than stable transformation. Fluorescent fusion proteins were often used in transient transformation to follow the in vivo behavior of proteins. Onion epidermis, which has large, living and transparent cells in a monolayer, is suitable to visualize fluorescent fusion proteins. The oft...
