Oxidative stress plays an important role in the pathogenesis of cardiovascular diseases. In the present study, we characterize three distinct phases of the H2O2-induced response, which leads to loss of mitochondrial membrane potential (DeltaPsi(m)) and subsequent cell death in cultured cardiac myocytes. (1) Priming: After H2O2 exposure (100 micromol/L), cells maintain a constant DeltaPsi(m) for...

welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

BACKGROUND Among NSAIDs acetyl salicylic acid remains as a valuable tool because of the variety of benefic prophylactic and therapeutic effects. Nevertheless, the molecular bases for these responses have not been complete understood. We explored the effect of acetyl salicylic acid on the heat shock response. RESULTS Peripheral blood mononuclear cells from rats challenged with acetyl salicylic...

Priming of circulating human eosinophils following late response to allergen challenge. D.J. Evans, M.A. Lindsay, B.J. O'Connor, P.J. Barnes. ©ERS Journals Ltd 1996. ABSTRACT: The eosinophil is recognized as an important effector cell in asthma. To investigate the role of eosinophils in the aetiology of asthma, we have examined whether peripheral blood eosinophils are primed following whole-lun...

Seed priming is widely recognized as a significant phenomenon for synchronizing germination and enhancing the vigor of seeds. Seeking importance priming, influence magnetic treatments in overall performance plants cannot be undermined well. In present study, seeds Pisum sativum L. Plantago ovata Forssk. were primed with essential Plant Growth Regulators (PGRs) such as; Gibberellic acid (GA3), P...

This study tested the hypothesis that priming the neutrophil respiratory burst requires both granule exocytosis and activation of the prolyl isomerase Pin1. Fusion proteins containing the TAT cell permeability sequence and either the SNARE domain of syntaxin-4 or the N-terminal SNARE domain of SNAP-23 were used to examine the role of granule subsets in TNF-mediated respiratory burst priming usi...

This study aims to determine the effect of different priming methods on viability and early growth upland rice under drought stress. Priming is an important approach improve resistance plants stress from germination phase growth, especially sub-optimal land. There are several efficient as seed pretreatment increase tolerance An effective method needed seedlings for application in dryland agricu...

Drought stress is a major environmental factor limiting crop growth and productivity. Hydrogen peroxide (H2O2) plays an essential role during response by acting as signal molecule that activates multiple tolerance mechanisms. In this study, the effects of H2O2 on agronomic traits were studied in rice (Oryza sativa L.) cv. Khao Dawk Mali 105 (KDML 105) was subjected to drought stress. applied ei...

ABSTRACT Brackish waters has been increasingly used in hydroponic systems for the cultivation of vegetables. However, its use can cause significant losses crop production. Therefore, new alternatives to enhance tolerance plants salt stress are being studied, including seed priming with hydrogen peroxide (H2O2). Thus, this study aimed assess H2O2 at different periods exposure enhancing productio...
