Much of law and ethics at the end of life turns on whether there is a moral and legal distinction between killing and letting die. That distinction, in turn, relies on a difference between intention (what one purposely aims to bring about in his actions) and foresight (what one merely believes to be likely or even substantially certain). On this distinction rests the plausibility of the legal p...

the writer in this article is going to illustrate that human rights and humanitarian law are applicable on detainees of guantanamo bay. of course ,we should know that although scope of our guantanamo bay discussions is about guantanamo bay detainee but our reasons are applicable on similar occasions .the writer does his best to refer to general comments of human rights committee this can increa...

Of William Heberden (1710-1801) Dr. Wells, in a letter to Lord Kenyon, wrote, 'Dr. Heberden, my Lord, stands in a manner alone in his profession. No other person, I believe, either in this or any other country, has ever exercised the art of medicine with the same dignity or has contributed so much to raise it in the estimation of mankind'. Heberden's modesty, integrity and scholarship earned hi...

During his long and productive career, Donald Yetter Gardner (1913-2004) played various musical instruments, directed church choirs, wrote contemporary church anthems and led many community-sponsored choral events. Additionally, he penned a number of popular spirituals, including "Man Shall Not Live By Bread Alone," and "O Give Thanks Unto the Lord". He was noted for his varied musical accompli...

We have expressed recombinant RNase P protein from Escherichia coli in high yield. A hexahistidine sequence at the amino terminus allowed protein purification in a single step. Mass spectrometry confirmed the molecular weight of the purified protein and indicated a purity of > 95%. Protein functionality was demonstrated by reconstitution of active holoenzyme.

Site-specific fluorescent labeling of proteins in vivo remains one of the most powerful techniques for imaging complex processes in live cells. Although fluorescent proteins in many colors are useful tools for tracking expression and localization of fusion proteins in cells, these relatively large tags (>220 aa) can perturb protein folding, trafficking and function. Much smaller genetically enc...
