Though medicines that target mRNA are under active investigation, there has been little or no effort to develop mRNA itself as a medicine. Here, we report the synthesis of a 130-nt mRNA sequence encoding a 33-amino-acid peptide that includes the sequ

[chemical reaction: see text]. A general route of converting alkenyl ketones to functionalized allenes was developed. Substituted 1,3-dien-2-yl triflates, which were prepared from the alkenyl ketones via silyl dienol ethers, were excellent substrates

Diseases of the colon and rectum. 22(4)
A case with diagnosis of benign cystic teratoma penetrating the rectal wall is presented. Teratoma of the rectum, primary or secondary, is not familiar and diagnosis is difficult. However, it is rather easy when teeth are found on x-ray or by colonos
