Liquid crystals and acupuncture

[Guest guest]

Hi Jim,

 

I failed to locate the reference. Medline has no hits for " liquid

crystals " and acupuncture. Acubriefs had only 3 hits on crystals,

but not the one that you sent. Here is one, but it is academic, IMO:

 

A. Moreno and M. Soriano-García (1999) Acta Cryst 55(2), Feb,

577-580 (short communications) Crystal-growth kinetics of protein

single crystals along capillary tubes in the gel-acupuncture

technique. Abstract: In attempts to obtain protein crystals of a

sufficient size for structural studies, lack of knowledge of the

physicochemical properties of protein solutions and of their crystal-

growth behaviour lead to a bottleneck for drug design as well as for

X-ray crystallography. Most formal investigations on crystal-growth

phenomena have been focused on equilibrium studies, where the

protein is soluble, and on the kinetics of crystal growth, which is

related to both nucleation and crystal-growth phenomena. The aim

of this work is to measure the crystal-growth rate along a capillary

tube used as a growing cell. These experiments were carried out

using the gel-acupuncture technique [García-Ruiz et al. (1993).

Mater. Res. Bull. 28, 541-546; García-Ruiz & Moreno (1994). Acta

Cryst. D50, 484-490; García-Ruiz & Moreno (1997). J. Cryst.

Growth, 178, 393-401]. Crystal-growth investigations took place

using lysozyme and thaumatin I as standard proteins. The maximum

average growth rate obtained in the lower part of the capillary tube

was about 35Ås-1 and the minimum average growing rate in the

upper part of the capillary tube was about 8Ås-1. The crystal-

growth rate as a function of the supersaturation was experimentally

estimated at a constant height along the capillary tube.

 

 

Best regards,
