Phycocyanin (PC) is a bioactive compound that can function as an antioxidant, anti-inflammatory, immunomodulatory, and anti-cancer agent. It act potential material in preventing COVID-19 curing those suffering from it. Spirulina platensis (SP) one of the microalgae rich proteins PC. This study aimed to determine optimum PC extraction SP, using distilled water solvent through freezing-thawing pr...
Background The provision, maintenance and promotion of the health of infants as a vulnerable group in health care services are a high priority, and the first step in reducing infant mortality and improving their health is undoubtedly the identification of their mortality status. We aimed to study the spatial distribution of premature infant mortality in 194 count...
This study examined shape changes in two typical wastewater flocs subjected to cyclic freezing and thawing and the associated force exerted by the ice front. While freezing, the engulfing ice front gradually pulled the floc apart. Subsequent thawing only partially restored the floc's shape. By the Maxwell model, used to interpret gross shape deformations, both flocs were visco-elastic objects e...
Introduction: Ecstasy is an amphetamine derivative, which its use has been consistently increasing over the past years. Ecstasy interacts with the glutamatergic system and it is known that glutamate receptors have a key role in learning and memory. The aim of this study was to investigate the interaction of ecstasy and glutamatergic system on learning and memory. Methods: Fifty-six male Wis...
Abstract Background: Oxidative damage to sperm resulting from reactive oxygen radicals and lipid peroxidation generated by the cellular components of semen during sperm freezing is possibly one of the main causes of the decline in motility during storage. The aim of this study was to evaluate the antioxidant effect of melatonin in different doses on oxidative stress and motility of cryo-pre...
introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...
Extended abstract 1- Introduction Water scarcity is currently one of the worldchr('39')s challenges, especially in arid and semi-arid regions; This is because population growth and rising living standards require more food and water. Therefore, excessive use of natural resources has led to the destruction of potential agricultural lands and natural resources. The final process is floods, dust...
The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...
The aim of the this study was to have a comparison between Zataria multiflora and Rosemarinus officinalis extractson quality of minced frozen silver carp preserved in cold storage temperature -18°C for six months. In this research, one control and three treatments of minced silver carp were prepared as Tr1 (+ Zataria), Tr2 (+Rosemary) and Tr3 (mixed with Rosemary and Zataria) all in normal pack...
