The aim of this study was to evaluate the physical and physicochemical properties of different brands of traditional (A, B and E), low calorie (C) and sugar-free (D) guava preserves. The results of these analysis indicated that there are differences in the physical and physicochemical properties of the different brands studied, and the partial and/or total exclusion of sugar from guava alters i...

Although it is agreed that physicochemical features of molecules determine their perceived odor, the rules governing this relationship remain unknown. A significant obstacle to such understanding is the high dimensionality of features describing both percepts and molecules. We applied a statistical method to reduce dimensionality in both odor percepts and physicochemical descriptors for a large...

The purpose of this study was to examine the relationships that exist between the elastic properties and the physicochemical properties of cortical bone in two groups of experimental animals. The animal model was the immature mutant dwarf rat, and the groups consisted of rats treated and not treated with recombinant human growth hormone (rhGH). The objective was to establish and broaden the qua...

This critical review examines in vitro and in vivo evidence for the influence of engineered nanomaterial (ENM) physicochemical properties on their distribution into, and effects on, the nervous system. Nervous system applications of ENMs; exposure routes and potential for uptake; the nervous system and its barriers to ENM uptake; and the mechanisms of uptake into the nervous system and overcomi...

background: development of safe radioprotector is a challenging task. in this study radioprotective effect of sucrose has been demonstrated in calf thymus dna (ctdna). sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around dna and effects of radiation on dna. hoechst 33258 was used to probe the possible alteration in physicochemical p...

9-nitrocamptothecin (9-nc) is a semisynthetic and a low soluble analogue of camptothecin alkaloids that target nuclear enzyme topoisomerase i. the unstable lactone form of 9-nc in biological fluids requires for its cytotoxic activity. to improve aqueous solubility and stability in biological media, 9-nc was loaded in polymeric nanoparticles. in this paper, we studied the effect of peg percent (...

Pure and calcium-doped silica and titanium dioxide thin films were prepared by the sol-gel method. Two different metallic substrates, i.e. stainless steel (316L) and titanium alloy (Ti6Al4V), were used for thin film deposition. Physicochemical properties and roughness of the thin films derived were investigated using the Raman spectroscopy, X-ray diffraction analysis, scanning electron microsco...

Dried carrot pomace (DCP) may be used as a thickening, coloring agent and also a carotenoid-fiber enriched component in food products formulations. The main objective of this study to investigate the effect of DCP from juice industries waste material on the physicochemical, rheological, nutritional properties of ketchup by partial replacement (0.7-3.5%) of tomato paste and the carboxy methyl ce...

Present research was an attempt to develop a statistical relationship between physicochemical properties of polymers and physical characteristics of fast disintegrating tablets of ibuprofen. Polymers are generally used in formulation to provide effective drug delivery give as well as good physical appearance. Here, several physicochemical properties of three different polymers were calculated a...
