From the water-soluble portion of the methanol extract of coriander (fruit of Coriandrum sativum L.), which has been used as a spice and medicine since antiquity, 33 compounds, including two new monoterpenoids, four new monoterpenoid glycosides, two new monoterpenoid glucoside sulfates and two new aromatic compound glycosides were obtained. Their structures, were clarified by spectral investiga...

Two experiments were conducted to evaluate the effects of providing a water-soluble globulin in the drinking water on growth performance of weanling pigs. In Exp. 1, 360 weanling pigs (5.0 +/- 1.2 kg; 17 +/- 3 d of age; PIC) were blocked by initial weight and allotted to one of six treatments in a 2 x 3 factorial arrangement. Treatments included three diet complexity regimens with or without wa...

Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubili...

in this research, the effect of water stress on the soluble sugars, starch and proteins content of two different cultivars (kaka and jam) of chickpea (cicer arietinum) was studied. the results showed that the soluble sugars increased while starch decreased during the stress in shoot and root of both cultivars. increasing of soluble sugars and decreasing of starch hall a positive correlation wit...

Background: The excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. Gum tragacanth (GT) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. Despite,  its desirable prop...

drought is considered as one of the most important limiting factors for oil seed canola plant(brassica napus l.) growth and productivity in iran. on the basis of root and shoot dry weight asaffected by water stress exerted by peg 6000, out of 9 canola cultivars, a relatively tolerant (cv. aghaii)and a sensitive cultivar (cv. po4) were selected. their responses to low water potential with respec...

A nanoscale modification strategy that can incorporate chondroitin sulfate (CS) into the cross-linked porous gelatin materials has previously been proposed to give superior performance for designed corneal keratocyte scaffolds. The purpose of this work was to further investigate the influence of carbodiimide chemistry on the characteristics and biofunctionalities of gelatin/CS scaffolds treated...

The water-soluble vitamins vary widely in chemical structure and properties, so it is not surprising that the characteristics of absorption of individual members of the group also show differences. Water-soluble vitamins are absorbed mainly into the blood, some very freely (e.g. ascorbic acid), others (e.g. thiamine) only in limited amounts. Vitamin Biz has an apparently unique mode of absorpti...

A facile and scalable preparation of aqueous solutions of isolated, sparingly sulfonated graphene is reported. (13)C NMR and FTIR spectra indicate that the bulk of the oxygen-containing functional groups was removed from graphene oxide. The electrical conductivity of thin evaporated films of graphene (1250 S/m) relative to similarly prepared graphite (6120 S/m) implies that an extended conjugat...

Ag nanoclusters consist of several to roughly a hundred atoms and possess sizes comparable to the Fermi wavelength of electrons; they exhibit molecule-like properties, including discrete electronic transitions and strong fluorescence. These nanoclusters are of significant interest because they provide the bridge between atomic and nanoparticle behavior in noble metals. Since the first observati...
