To elucidate the role of electrical signalling in the phloem of maize the tips of attached leaves were stimulated by chilling and wounding.Two different signals were detected in the phloem at the middle of the leaf using the aphid stylet technique: (i) action potentials (AP) arose in the phloem after chilling; and (ii) variation potentials (VP) wer

To determine whether NOX 5 is expressed in rabbit corneal stromal cells (RCSC).NADPH oxidases (NOXes) are enzymes that preferentially use NADPH as a substrate and generate superoxide.Several isoforms of NOXes function as multi-protein complexes while NOX5 and DUOXs do not require the accessory proteins for their activity and possess calcium binding

Stimulants are effective in treating attention-deficit/hyperactivity disorder (ADHD).Psychiatrist Charles Bradley first made this discovery in 1937 when he found that children treated with amphetamines showed improvements in school performance and behavior.Between 1995 and 2008, stimulants to treat ADHD increased six-fold among American adults and

Abstract The mechanisms of Pb(II) toxicity have been studied in human red blood cells using confocal microscopy, immunolabeling, fluorescence-activated cell sorting and atomic force microscopy.The process follows a sequence of events, ceramics starting with calcium entry, followed by potassium release, morphological change, generation of ceramide,
