Individual Differences of Acupuncture Analgesia in Humans Using cDNA Microarray

Individual differences of acupuncture analgesia in humans using cDNA microarray.

A large amount of evidence suggests that acupuncture stimulation enhances the experimental pain threshold in various animal models. Acupuncture analgesia is mediated by the endogenous opioid system, and the analgesic response to acupuncture shows individual variation. This study identified and characterized the genes that differ between high responders (HR) and low responders (LR) on acupunctur...

cDNA microarray image segmentation using root signals

A vector processing based framework suitable for cDNA microarray image segmentation is introduced and analyzed in this paper. By using nonlinear, generalized selection vector filters the framework proposed here classifies the cDNA image data as either microarray spots or image background. The solution converges to a root signal that represents the segmented cDNA microarray image with the regula...

Preoperative acupuncture: postoperative analgesia?

In the linked study by Coura and collaborators , it is reported that acupuncture the day before surgery can reduce postoperative pain (see article on page 16). 1 Although the study is small and there are gender differences between the groups, the fi ndings are novel, suggesting that acupuncture may be used the day before surgery rather than given in the immediate preoperative period. This sugge...

Spotted cDNA microarray image segmentation using ACWE

The segmentation of the picture (and, implicitly, the segmentation method used) is one of the three important steps in microarray image processing, together with spot gridding and information extraction. It directly affects the accuracy of gene expression analysis in the data mining process that follows. In 2001 a segmentation method for arbitrary pictures using the Active Contours Without Edge...
