The conformational dynamics of enzymes is a computational resource that fuses milieu signals in a nonlinear fashion. Response surface methodology can be used to elicit computational functionality from enzyme dynamics. We constructed a tabletop prototype to implement enzymatic signal processing in a device context and employed it in conjunction with malate dehydrogenase to perform the linearly i...
Diagnosis of myocardial infarction is very important in a patient with chest pain. Chest pain is not always present or it may be from other causes rather than myocardial infarction. Q wave is present in 30] of infarction. ST,T wave changes are present in all myocardial infarctions, but these changes also are present in myocardial ischernia. For these reasons diagnosis of myocardial infarction...
Introduction : The vitreoretinal interface is involved in a wide range of vitreoretinal disorders and separation of the posterior vitreous face from the retinal surface is an essential part of vitrectomy surgeries. A diverse range of enzymatic and non-enzymatic agents are being studied as an adjunct before or during vitrectomy to facilitate the induction of posterior vitreous detachment. Ther...
Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...
Silicon (Si) can protect some plants from biotic and abiotic stresses. In this research, effects of three exogenous Si levels (0, 0.85 and 1.7 mM) on growth, lipid peroxidation, lipoxygenase activity, proline content, H2O2 accumulation, and activity of non-enzymatic and enzymatic antioxidants (catalase and ascorbate peroxidase) under powdery mildew disease stress by Sphaerotheca fuliginea on pu...
Nowadays, the use of a wide range of medicinal herbs such as saffron and its aromatic compounds is increasingly being regarded as natural sources of antioxidant properties. In addition to saffron stigma, saffron petal is a rich herbal source of antioxidant compounds. The present study was conducted in a completely randomized design with three replications to study some of the enzymatic and non-...
This experiment was conducted to evaluate the effects of foliar application of different K:Ca ratios (0, 0.5, 1 and 1.5) on growth parameters, yield and fruit quality of strawberry 'Selva' in greenhouse conditions based on completely randomized design with three replicates. Based on the results, spray application showed significant effects on the photosynthetic capacity, enzymatic and non-enzym...
Abstract Salicornia europaea L. is a common halophytic plant species distributed in many saline soils and habitats, including margins of many wetlands. Salicornia europaea grows around Mighan Wetland, a natural desert ecosystem in central Iran with fluctuating water levels due to constant heat and severe wind throughout the year. Although, aspects of biology and ecology of halophytes growi...
The atricle presents modern data on the composition and role of antioxidant system in human body.The stages components (enzymatic non-enzymatic) are considered, classifications given. Its participation pathogenesis diseases progression has been proven.
