Box-like tetrakis(metalloporphyrin) supramolecular assemblies possessing Zn and Al metal sites can catalyze the methanolysis of phosphate triesters with a high rate enhancement, up to 430 times faster than the uncatalyzed reaction. Mechanistic studies suggest that the observed rate enhancement can be attributed to a high local concentration of methoxide ion that operates in concert with a solvo...

Wolfram Hörz 1944–2005

Fields of research are frequently cultivated by a few scientific entrepreneurs whose vision and drive inspire the rest of us. The analysis of chroma-tin structure and function has profited immensely from leaders such as Wolf-ram Hörz. The yeast PHO5 promoter model developed by Wolfram Hörz has become a paradigm for dissecting the events underlying promoter-specific chro-matin opening in respons...

Alexis Carrel (1873-1944)

Alexis Carrel [5] was a doctor and researcher who studied tissue cultures. He continued Ross Granville Harrison?s research and produced many improvements in the field of tissue culture and surgery. He was the recipient of the 1912 Nobel Prize in Physiology or Medicine [6] for his development of surgical techniques to repair blood vessels. Carrel was born on 28 June 1873 in Sainte-Foy-les-Lyon, ...

The Medical Annual, 1944

that given here, applies the term pyloric canal to the passage through the pyloric sphincter in X-ray photographs of the stomach (fig. 4) and in the description of the movements of the stomach. Most radiologists still use the terms pyloric antrum or pre-pyloric segment for what is anatomically the pyloric canal, though Shanks (1938) uses the terms pyloric canal and pylorus as synonymous, statin...
