Traditional Chinese acupuncture and placebo (sham) acupuncture are differentiated by their effects on μ-opioid receptors (MORs)

Controversy remains regarding the mechanisms of acupuncture analgesia. A prevailing theory, largely unproven in humans, is that it involves the activation of endogenous opioid antinociceptive systems and μ-opi...

Analysis of Type II Restriction Endonucleases that Interact with Two Recognition Sites

Many students of molecular biology know for certain that the Type II restriction endonucleases are dimeric proteins that recognise a palindromic DNA sequence, 4–8 bp (base pairs) long, and cut this single sequ...

Intraoperative ultrasound and prophylactic ursodiol for gallstone prevention following laparoscopic gastric bypass

Background: Previous studies have shown that ursodiol decreases gallstone formation from 32% to 2% following open gastric bypass, but no data exist on laparoscopic Roux-en-Y gastric bypas...

The physical maps for sequencing human chromosomes 1, 6, 9, 10, 13, 20 and X

We constructed maps for eight chromosomes (1, 6, 9, 10, 13, 20, X and (previously) 22), representing one-third of the genome, by building landmark maps, isolating bacterial clones and assembling contigs. By th...
