BACKGROUND The incidence of postoperative nausea and vomiting (PONV) is 50 to 79% after neurosurgery. Our study is designed to evaluate the efficacy of pericardium 6 (P6; also known as Neiguan) acupoint stimulation versus placebo, and versus routine antiemetic for the prevention of PONV after craniotomy, as well as to compare the efficacy of invasive acupuncture with non-invasive transcutaneous...

The C terminus of the HIV-1 Gag protein contains a proline-rich domain termed p6(Gag). This domain has been shown to play a role in efficient virus release and incorporation of Vpr into virions. In a previous study (X. F. Yu, L. Dawson, C. J. Tian, C. Flexner, and M. Dettenhofer, J. Virol. 72:3412-3417, 1998), we observed that the removal of the p6 domain of Gag as well as drastic mutations in ...

Tertiary folding of the 160-nt P4-P6 domain of the Tetrahymena group I intron RNA involves burying of substantial surface area, providing a model for the folding of other large RNA domains involved in catalysis. Stopped-flow fluorescence was used to monitor the Mg2+-induced tertiary folding of pyrene-labeled P4-P6. At 35 degrees C with [Mg2+] approximately 10 mM, P4-P6 folds on the tens of mill...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. We read with great interest the article by Etri M et al. about the effects of P6 acupressure on pain and vital signs of patients following small abdominal surgeries (1). Post-operative pain is often experienced by surgical patients, with practical consequences on clinical ...

to evaluate the capability of irs-p6 liss-iii data to be employed for monitoring the pollarding forest areas in northern zagros, some parts of pollarded forests located around baneh city were selected as a case study area. the pollarding area was determined as the ground truth in a 3-year alternation period using a global positioning system (gps). radiometric and geometric corrections were appl...

The crystal structures of the [A(1)(2)][A(2)(3)](BO(4))(3)X apatites and the related compounds [A(1)(2)][A(2)(3)](BO(5))(3)X and [A(1)(2)][A(2)(3)](BO(3))(3)X are collated and reviewed. The structural aristotype for this family is Mn(5)Si(3) (D8(8) type, P6(3)/mcm symmetry), whose cation array approximates that of all derivatives and from which related structures arise through the systematic in...

Parvovirus B19 infections are associated with diverse clinical manifestations, ranging from no symptoms to severe symptoms. The virus shows an extreme tropism for replication in erythroid progenitor cells, possibly due to the activity of the only functional promoter (p6) of the B19 virus genome in combination with both cell- and cell cycle-specific factors and the trans-activator protein NS1. A...
