samanoo is a traditional iranian dessert that has a high nutritional value. its consumption is on the rise.samanoo is made using a mixture of wheat sprout extract (wheat malt) and whole wheat flour. it is mainlyprepared at home or at in small businesses and there is no standard method of preparation. this studyinvestigates the effects of wheat cultivar (hirmand and tabasi) and the ratio of whea...

The permeability of the cornea to drugs is clinically important because it is the major factor determining the efficacy of topically applied ophthalmic preparations. With this perspective, the present article gives a brief update and overview of corneal structure and proposed mechanisms of permeation. Physiological, physicochemical and formulation factors affecting drug permeation through corne...

Supercritical carbon dioxide (scCO2) could be one aspect of a significant and necessary movement towards green chemistry, being a potential replacement for volatile organic compounds (VOCs). Unfortunately, carbon dioxide has a notoriously poor solubilising power and is famously difficult to handle. This review examines attempts and breakthroughs in enhancing the physicochemical properties of ca...

The specificity of carbohydrate-protein interactions can greatly outstrip that of many other ligand-binding systems; such is the enormous density of information that sugars can convey. In addition, macromolecules allow for the fine-tuning of active drug delivery through their great ability to undergo site-specific modification and their inherent physicochemical properties. Once combined, these ...

The control of genotoxic impurities (GTIs) is a crucial activity that is performed for any new chemical entity intended for clinical use. A key element of this is the quality risk assessment. This article seeks to examine the primary components of such a strategy, focusing specifically on the effective use of in silico assessment tools to augment this process, in particular the calculation of t...

The approaches range from theoretical studies – including statistical physics of non-equilibrium systems – to the organic synthesis of molecules and macromolecules, and they include many experimental studies on biological and biomimetic systems in which the parameters can be changed. A variety of microscopical techniques are used such as optical, multiphoton, electron and atomic force microscop...

Many old paintings suffer from the effects of certain physicochemical phenomena, that can seriously degrade their overall visual appearance.Digital image processing techniques can be utilized for the purpose of restoring the original appearance of a painting, with minimal physical interaction with the painting surface. In this paper, a number of methods are presented which can yield satisfactor...

Although many sequences and linear IgE epitopes of allergenic proteins have been identified and archived in databases, structural and physicochemical discriminators that define their specific properties are lacking. Current bioinformatics tools for predicting the potential allergenicity of a novel protein use methods that were not designed to compare peptides. Novel tools to determine the quant...

AbstractMedication errors are commonly encountered in hospital setting. Intravenous medications pose particular risks because of their greater complexity and the multiple steps required in their preparation, administration and monitoring. We aimed to determine the rate of errors during preparation and administration phase of intravenous medications and the correlation of these errors with the d...
