...Show More Authors
Abstract<p>Laboratory studies were carried out to investigate the differences between uninfested and infested bitter orange <italic>Citrus aurantium</italic> leaves with oriental yellow scale <italic>Aonidiella orientalis</italic> in Iraq. From this experiment, it is reasonable to determine that releases of volatile organic compounds from both uninfested and infested bitter orange <italic>C. aurantium</italic> as a response to the infestation of the oriental yellow scale <italic>A. orientalis</italic>. Some volatile organic compounds were found in uninfested leaves, while GC-MS did not detect others. Infested leaves by oriental yellow scale insects emitted significantly D-Limonene and β- Ocimene more than uninfested leaves of bitter orange. In contrast, the uninfested leaves emitted the compound Alloaromadendrene more than infested bitter orange. The changing of chemical profile in the bitter orange leaves can explain the response of citrus trees to the infestation of oriental yellow scale <italic>A. orientalis</italic> as a way of pest control by repellence insect pests or attractive the beneficial insects.</p>

The Level of Nitric Oxide Synthase and Nitric Oxide in Hypertensive Women
...Show More Authors

Hypertension is a cardiovascular problem with high rates of epidemiology and risks of morbidity and mortality in the global area. Nitric oxide (NO) is one of the reactive oxygen species (ROS) that produced from L-arginine by nitric oxide synthase (NOS) enzyme. NO involves in various vital processes in human health, one of which is the modulation of vasoconstriction and relaxation of the vascular system. We have aimed to investigate the link between NO and NOS with hypertension in women. The relationship between NO and NOS, as well as the usefulness of them as indicators of hypertension risks were subjects of study in this article. The results have revealed that hypertensive women had significant (P<0.05) lower levels of NO (15.07±3.41 IU/m
