amyotrophic lateral sclerosis mimic ‎syndromes

amyotrophic lateral sclerosis (als) misdiagnosis has many broad implications for the patient and the neurologist. potentially curative treatments exist for certain als mimic syndromes, but delay in starting these therapies may have an unfavorable effect on outcome. hence, it is important to exclude similar conditions. in this review, we discuss some of the important mimics of als.

Does Nature Prefer Heterocycles?

Utilizing redox-chemistry to elucidate the nature of exciton transitions in supramolecular dye nanotubes.

Supramolecular assemblies that interact with light have recently garnered much interest as well-defined nanoscale materials for electronic excitation energy collection and transport. However, to control such complex systems it is essential to understand how their various parts interact and whether these interactions result in coherently shared excited states (excitons) or in diffusive energy tr...

A simple mimic.

ing at the University of Arizona. Saadatmanesh developed the material, called CarbonWrap, about six years ago and now sells it through CarbonWrap Solutions. The polymer is made of woven filaments of glass, carbon and Kevlar, which are placed in a resin matrix. Its tensile strength—the force required to pull it apart—is about 200 tons per square inch, 10 times stronger than steel. The fiber cost...

A photoresponsive glycosidase mimic.

Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic acid groups from the (E)-form occurs simultaneously, whereas in the (Z)-form it occurs in a stepwise fashion. The mono anionic form of the (Z)-isomer acts as a glycosidase mimic that proceeds through a general acid-general base catalytic mechanism. This is the first example of a phot...
