background : vitiligo is an acquired disease of skin that presents with depigmented patches due to lack of melanocytes in the epidermis. accumulation of toxic free radicals like hydrogen peroxide in the epidermis may be responsible for melanocytes death. since ethyl vanillate (vanillic acid ethyl ester) is a strong hydrogen peroxide scavenger, it may be effective against vitiligo. this study wa...

in this work, the effects of acetic and lactic acids addition to rice during cooking, on the texture and morphological properties, and too, the gelatinization temperature (gt) of the cooked domsiyah rice was investigated. all experiments were carried out in triplicate and data analyzed in randomized completely by spss15 software. the results showed that acid addition to rice during cooking caus...

an efficient and simple procedure for the synthesis of 1,8-dioxo-octahydroxanthenes from the aromatic aldehydes and 5,5-dimethylcyclohexane-1,3-dione (dimedone) in the presence of boric acid [bo3h3 or b(oh)3] as an inexpensive and reusable catalyst is described. the salient features of this methodology are: the elimination of corrosive liquid acids, high yields, simple methodology, short reacti...

background & aim: sage (salvia officinalis l.) is a perennial medicinal herb which belongs to lamiales order and lamiaceae family. this plant has economical value for four years. nowadays the use of plant growth regulators (pgr) has an important role for increasing the secondary metabolites in plants. among pgrs jasmonic (ja) and salicylic acid (sa) have many applications in medicinal plant...

single walled nanotubes (swnt) are common interested nanovehicle to make biosensors more sensitive.carbon nanotubes (cnts) have many distinct properties make them to be exploited to develop the nextgeneration of such nano sensors .the keto-enol tautomerization is one of the most common investigatedsubjects of isomerism in this regards, sensors are devices that are able to detect and change the ...

the aim of this work was to study the ability of two biodegradable chelating agents, nitrilotriaceticacid (nta) and ethylenediiminopropanedioic acid (eddm) to complex metals, in the treatment of the pulp,prior to a totally chlorine free (tcf) bleaching process, and compare with the ethylenediaminetetraacetic acid(edta) performance. firstly, speciation efficiency index (sei) was calculated by co...

background and objective: recent studies have shown that not only the quantity, but also the quality of dietary fatty acids can affect lipid parameters. elaidic acid is a major hydrogenated by-product of vegetable oil play a role in the development of cardiovascular disease, especially atherosclerosis, through changing lipid profile and increase in inflammation and inflammatory factors. on the ...
