the synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.

background: acanthamoeba castellanii is the important cause of amoebic keratitis in iran. the key molecule in pathogene­sis of acanthamoeba keratitis is mannose binding protein (mbp) led to adhesion of amoeba to corneal epithelium. subse­quent to adhesion other cytopathic effects occur. the goal of this study was to identify the molecular characterization of a gene encoding mbp in an iranian is...

the isolation and characterization of two new isoquinoline alkaloids, dehydropuntarenine and dehydrosaulatine, obtained during the column chromatography of an alkaloidal fraction from the roots of b. actinacantha (berberidaceae) are described.

The engineering of biological systems can be greatly aided by better models, derived from high-quality characterization data, and by better means for designing and debugging new genetic circuits. Web-based tools and repositories have proven a successful approach to distributing such techniques, particularly because the centralization of infrastructure greatly decreases adoption cost for new use...

High throughput immune repertoire sequencing is promising to lead to new statistical diagnostic tools for medicine and biology. Successful implementations of these methods require a correct characterization, analysis and interpretation of these datasets. We present IGoR – a new comprehensive tool that takes B or T-cell receptors sequence reads and quantitatively characterizes the statistics of ...

We propose a new algebraic framework to discuss and classify recognizable tree languages, and to characterize interesting classes of such languages. Our algebraic tool, called preclones, encompasses the classical notion of syntactic Σ-algebra or minimal tree automaton, but adds new expressivity to it. The main result in this paper is a variety theorem à la Eilenberg, but we also discuss importa...
