BACKGROUND The immune response to bacterial antigens on mucosal surfaces may be modified in individuals allergic to aeroallergens due to a maturational or genetic difference or from the interaction between inhaled allergens and bacteria at the mucosa. METHODS Plasma from children and adults allergic (n = 97) and non-allergic (n = 54) to aeroallergens were initially tested for IgG1 (Th1) and I...

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 ...
