Magnetic measurements showed that compounds up to 10% of Mn doping are paramagnetic with antiferromagnetic
interactions. However, higher Mn doped compound exhibits local ferrimagnetic ordering. Thus, no ferromagnetism has been observed for all Mn-doped tetragonal ZrO2 samples. (C) 2011 American Institute of Physics. [doi:10.1063/1.3626788]“
“Roots of Astragalus membranaceus (A. membranaceus) (Astragali Radix, AR) has been used as a herbal medicine for gastrointestinal disorders in China, Korea, Japan, and other Asia countries. In this study we investigated the effects of the AR 70% ethanol extract and compounds isolated from AR on gastritis in rats and growth of human gastric cancer cells. AR 70% ethanol extract showed the potent acid-neutralizing capacities click here and partly cytotoxicity of Helicobacter pylori and human AGS gastric cancers cell. Astragaloside I and daucosterol, which were isolated from AR, significantly
inhibited HCl/ethanol-induced gastric lesions. In addition, daucosterol increased the mucus content to almost the same as the positive control. Danusertib The results of this study suggest that astragaloside I and daucosterol may be good candidates for the development of new drugs or neutraceuticals which can be used for the treatment or prevention of gastritis.”
“Prolonged first and second stage of labor, isolated prolongation of the second stage, forceps delivery or vacuum extraction, perineal laceration, nulliparity and epidural anesthesia are known risk factors for developing prolonged postpartum urinary retention (PUR). The aim
of our study was to analyze number and constellations of these risk factors, in prolonged postpartum urinary retention (PPUR) in our own unit to facilitate the identification of patients at high risk and thus to prevent bladder overdistension by early intervention.
We performed a retrospective analysis of all our cases with PPUR between 2003 and 2008 including variables like age weight, height, body mass index, fetal birth weight and head circumference.
The H 89 clinical trial incidence of PPUR at our institution is low being 0.06%. No woman combined all six risk factors. The majority had five risk factors, all had at least four. An isolated prolonged second stage of labor was common to all patients with PPUR. Five women had an epidural anesthesia, three were nulliparous and only two women delivered spontaneously. All but one woman suffered from perineal tears. Interestingly, fetal head circumference was larger than 36 cm in four of six cases.
In contrast to simple PUR, the prolonged form of PUR could be the result of a cumulative effect of different single risk factors.”
“Low-viscosity hyperbranched epoxy resin-containing nitrogen heterocycle (HTPE) is synthesized from epichlorohydrin (ECH), dimethylol propionic acid (DMPA), and tris(2-hydrooxyethyl)-isocyanurate. The structure and properties of HTPE are characterized by FTIR, GPC, and molecular simulation.
