Combined Reduced 4D 13C Exchange and 1H Spin Diffusion Experiment for Determining the Length Scale of Dynamic Heterogeneities

✍ U. Tracht; M. Wilhelm; A. Heuer; H.W. Spiess 📂 Article 📅 1999 🏛 Elsevier Science 🌐 English ⚖ 141 KB

A multidimensional static solid-state NMR experiment is described that combines 13 C exchange sequences with 1 H spin diffusion. It realizes a spatial correlation of different reorientation rates. By means of this experiment the length scale of dynamic heterogeneities can be measured directly. The p

## Abstract PFG‐NMR methods were used to measure the translational diffusion coefficients for the Aβ peptide involved in Alzheimer's disease and also for a series of fragments of this peptide. The peptides ranged from a pentamer to the full length Aβ(1–40). They were studied at 25° C and physiologi

Acute and Chronic Toxicity of Veratrum V

Acute and Chronic Toxicity of Veratrum Viride††The Veratrum viride studied was the whole-powdered drug marketed by Irwin, Neisler & Co. under the name, Vertavis. The work reported herein was supported by a grant from this firm. The batch of powder used in these experiments was stated by the manufacturer to have been assayed biologically by the Craw method on Daphnia magna. One Craw unit of the material studied was stated to be 15.6mg. With regard to this assay, Mr. R. O. Craw has been so kind as to allow us to publish a brief explanation: A reference lot of Yerolrum oirid; powder was set-aside as a standard and a 10% w/v aqueous extract was made of this powder. The average median length of life in 50 assays of 1000 daphnia on immersion in the solution was determined to be 2.22 hours. The daphnia were considered dead when the heart was found to be in systolic standstill on microscopic examination. Succeeding lots of powder were assayed and their potency determined by relating the median length of life of daphnia to 2.22 hours, which is one unit. Twenty assays of 10 animals each were used on each lot of powder.‡‡The authors wish to thank Dr. J. F. A.,McManus of the Department of Pathology for a pathologic report on the tissues, and Mr. James Thomas and Mrs. Bobby E. Teague for technical assistance.
