selenium is an essential element for humans, therefore, adding it to plants is convenient for biofortification. thus, the aim of this work was to analyze experimentally the ability of sodium selenite to increase the concentration of se and modify the antioxidant activity in tomato plants. we used plants of the toro hybrid variety and applied three treatments: 0, 2 and 5 mg l-1 of selenium as so...

previously, we reported that the kaempferol and kaempferol-7- o -glucoside isolated from securigera securidaca showed potent anti-hsv activity. in the present study the anti-hiv-1 activities of kaempferol and kaempferol-7- o -glucoside are investigated at different concentrations (100, 50, 25 and 10 µg/ml) using hiv-1 p24 antigen kit. real-time polymerase chain reaction (rt-pcr) assay was also ...

background: bone-specific alkaline phosphatase (bap) is synthesized by the osteoblasts and is presumed to be involved in the calcification of bone matrix, though its precise role in the formation process is unknown. the aim of the present study was to measure the bap activity in paget's and normal specimens by two different techniques. methods: total alp (tap) as well as bap activity-measu...

background: with increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. the changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. these changes clearly appear in specification of photoplethysmogram particularly in the size and...
