nanopartmles have been used as an approach to improve the pharmacodynamic and phannacokinetie propertiesof various drues. amino acids have been considered to be useful to make such nano particles because ofthocompatithe and biodegradable characteristic. the quantum mechanical method that was chosen to analyze inethio hexa peptide nano ring]. the structure of some peptide nanorrigs as well as th...

The Bioinformatics Links Directory, http:// bioinformatics.ca/links_directory, is an actively maintained compilation of servers published in this and previous issues of Nucleic Acids Research issues together with many other useful tools, databases and resources for life sciences research. The 2007 update includes the 130 websites highlighted in the July 2007 Web Server issue of Nucleic Acids Re...

The nonconventional yeast Yarrowia lipolytica has been developed as a versatile and attractive tool for a large variety of biotechnological applications. This yeast has several physiological properties with industrial significance. Y. lipolytica uses hydrophobic substrates such as n-alkanes, oils, fats, and fatty acids as low-cost carbon sources. The yeast is able to produce a set of diverse ad...

Benzoic acids are highly important structural motifs in drug molecules and natural products. Selective C-H bond functionalization of benzoic acids will provide synthetically useful tools for step-economical organic synthesis. Although direct ortho-C-H functionalizations of benzoic acids or their derivatives have been intensely studied, the ability to activate meta-C-H bond of benzoic acids or t...

Admixtures and the water have an important role on application of concrete. The study is aimed at investigating the effect of strong acids as mixing water on setting times, soundness and compressive strength of admixture cements. This paper therefore presents the result and findings of an experimental research on the influence of strong acids on setting and strength development of admixture cem...

Wheat aleurone, due to its potentially higher bioaccessibility and bioavailability of micronutrients and phenolic acids, could represent a useful ingredient in the production of commonly consumed cereal-based food. The aim of the present study was to investigate the in vitro bioaccessibility of phenolic acids both from an aleurone-enriched bread and from a whole grain bread. The two bread sampl...

The separation (or removal) of organic residues from aqueous waste streams released from industries is important and essential from the points of view of pollution control and recovery of useful materials. The disposal of waste waters containing most widely-used industrial organic acids such as acetic acid, formic acid and propionic acid has been recognized as a significant expense to the indus...

A library of oligomeric compounds was synthesized based on the imidazole-4,5-dicarboxylic acid scaffold along with amino acid esters and chiral diamines derived from amino acids. The final compounds incorporate nonpolar amino acids (Leu, Phe, Trp), polar amino acids (Ser, Asp, Arg), and neutral amino acids (Gly, Ala), and were designed to be useful in screening for inhibitors of protein-protein...

We have reported the incorporation of labeled amino acids into the proteins of rabbit bone marrow cells in vitro (l), a study that was undertaken to compare the process in intact cells as compared with tissue slices and homogenates. Bone marrow cells are a mixture in different stages of maturity. The uptake of labeled amino acids by rat diaphragm was studied because it is an adult tissue with p...
