We investigated the role that manganese superoxide dismutase (MnSOD), an important antioxidant enzyme, may play in the drought tolerance of rice. MnSOD from pea (Pisum sativum) under the control of an oxidative stress-inducible SWPA2 promoter was introduced into chloroplasts of rice (Oryza sativa) by Agrobacterium-mediated transformation to develop drought-tolerant rice plants. Functional expre...

native population of raspberry fruits (rubus spp) were treated with methyl jasmonate (mj) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?c. the result of experiment revealed that berries treated with methyl jasmonate (mj) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

modern biotechnology and genetic engineering using techniques and special ‎laboratory tools plays an important role in the pharmaceutical industry and medicinal ‎plant propagation. among these techniques, it can be noted that a wide range of ‎elicitors are widely used for inducing metabolites at invitro culture. due to the ‎pharmaceutical properties of artichoke and its history, it has been dee...

Now-a-days leakage power is an important issue in microprocessor’s and hardware’s. In modern computer systems memory components covers 70 to 80 percent of total area of microprocessors that means memory contains more number of transistors. Generally leakage power dissipation proportional to the number of transistors. So the leakage power dissipation is more in the memories. In high performance ...

dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...

Salicylic acid (SA) is a key molecule that alleviates abiotic stress in many plant species. In this study, the role of SA was examined to moderate lead (Pb) toxicity in the basil (Ocimum basilicum). The experimental design was a randomized complete block design with 4 levels of PbNO3; 0 (control), 100, 200 and 300 mg kg-1 of soil as the first factor, and the foliar application of SA at 3 levels...

BACKGROUND In patients with acute exacerbations of chronic obstructive pulmonary disease, noninvasive ventilation may be used in an attempt to avoid endotracheal intubation and complications associated with mechanical ventilation. METHODS We conducted a prospective, randomized study comparing noninvasive pressure-support ventilation delivered through a face mask with standard treatment in pat...

The effect of plant growth substances (IAA, 2,4-D, zeatin, kinetin, zearalenone) were studied on membrane properties of the cells of embryogenic (E) and non-embryogenic (NE) calli derived from immature inflorescences (inf) or embryos (emb) of winter wheat. Calli initiated from inflorescences show higher permeability. The ion leakage from cells of E calli was higher than from cells of NE calli. ...
