Biological roles of crop NADP-malic enzymes and molecular mechanisms involved in abiotic stress
The abiotic stress tolerance of plants is very important for plant growth, development, survival and functional performance. NADP-ME is one of the most important enzymes in plants. Studying the role that NADP-malic enzyme plays in many metabolisms may help researchers improve the plant abiotic tolerance. The studies on NADP-ME in plants focus on its activity under different stresses. The regulation of NADP-ME gene...

Transfusion-transmitted virus (TTV) is an unenveloped circular single-stranded DNA virus with a diameter of 30 to 32 nm that was first described in 1997 in Japan. TTV was detected in various populations without proven pathology, including blood donors and in patients with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV). The aim of this study was to determine the prevalence of TTV DNA in...

Antifungal activity of bacterial strains from the rhizosphere of Stachytarpheta crassifolia
This study evaluated the antifungal action of biomolecules produced from the secondary metabolism of bacterial strains found in the rhizosphere of semi arid plants against human pathogenic Candida albicans. Crude extracts were obtained using ethyl acetate as an organic solvent and the bioactivity was assessed with a bioautography technique. The results showed that bacterial...

Simple model to study the effect of temperature on the greenhouse with shading nets
Due to high solar intensity, the internal temperature of greenhouses in subtropical regions is so high that it is difficult for crops to survive. There are two types of shading nets that are applied to reduce the solar intensity entering the greenhouse. The purpose of this research is to develop a simple greenhouse model to describe the effect of these shading nets on the inside temperatures of a greenhouse. The thermal...

Effect of drying methods on the physico-chemical properties of soyflour
This study investigated the relationship between the drying methods and the physicochemical properties of soybean during drying prior to converting it into flour. Three samples were prepared for each of Tax 1485 and mixed varieties. A sample for each variety was subjected to a drying method. The three drying methods used are roasting, oven and sun drying. The dried samples were converted to flour in attrition mill....

Ultrasonic extraction of flavonoids and phenolics from loquat (Eriobotrya japonica Lindl.) flowers
Ethanol was used to extract flavonoids and phenolics from loquat (Eriobotrya japonica Lindl. cv. Ruantiaobaisha) flowers with ultrasonic pharmaceutical managing machine. Single-factor and orthogonal experiment were used to investigate the optimum extraction condition. The results showed that, the combination of 30°C, 80 min, 60% ethanol and 1:40 material ratio was optimum extraction condition with the...
