We consider the pulsar velocity problem and relate it to some unconven-tional neutrino oscillation mechanisms based on a violation of the equivalence principle by neutrinos. We show that the observed pulsar velocities may be explained by violations at the level from 10 −9 to 10 −10 in the case of a non-universal tensor neutrino-gravity coupling, whereas there is no solution in the case of a non...

OBJECTIVES To review the efficacy, safety, costs, and subsequent reproductive outcome of surgical and nonsurgical management of ectopic pregnancy (EP). DESIGN Pertinent studies were identified through computer Medline search. The rates of intrauterine pregnancy (IUP) and EP were calculated from the raw data in the original publications so that the denominator would be consistent. RESULT(S) ...

a simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (ne) and epinephrine (ep), in serum samples was developed. the method is based on the fluorescence sensitization of terbium (tb3+) by complexation with both catecholamines in the presence of lanthanum (la3+), as a co-cation, and in a na2so3 solution (chemical deoxygen...

This study was done to investigate aspects of control of extrarenal erythropoietin (Ep) production. To this end we studied the effects of three stimuli of renal Ep production in the adult, i.e. hypoxia, cobalt, and activation of adenylate cyclase on Ep generation by cultured fetal mouse liver cells. The fetal liver was taken as a model for extrarenal Ep production because this organ is consider...

OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of echo-planar diffusion-weighted magnetic resonance imaging (EP-DWI) and high-resolution computed tomography (HRCT) in the detection and localization of cholesteatoma. MATERIALS AND METHODS Fifty-four patients were prospectively included in this study. Patients with suspected primary or residual cholesteatoma were evalua...

Erythropoietin (Ep), insulin, and prostaglandins E1 and A1 (PGE1, PGA1) enhanced heme synthesis by mitochondria isolated from embryonic and adult mouse liver cells. The combination of Ep with PGE1 had an antagonistic effect, while that of Ep with PGA1 gave an additive result. The capability of isolated human platelet mitochondria to synthesize heme was also shown. This activity was stimulated b...

We have recently shown that the prostaglandin E(2) (PGE(2)) receptor EP(3) plays an important role in suppression of colon cancer cell proliferation and that its deficiency enhances late stage colon carcinogenesis. Here we examined the effects of EP(3)-deficiency on two-stage skin carcinogenesis. 7,12-Dimethylbenz[a]anthracene (50 microg/200 microl of acetone) was thus applied to the back skin ...

Objective Many previous studies have reported that pain symptoms can lead to significant brain function and anatomical changes, whereas the intrinsic brain activity changes in acute eye pain (EP) patients remain unknown. Using the amplitude of low-frequency fluctuation (ALFF) method, this study aimed to evaluate the spontaneous brain activity alterations and their relationships with clinical fe...

(Ep) production was studied in control and nephrectomized sheep fetuses beginning at about 100 d of gestation. Fetuises were given injections of either 1.2 mg/d x 13 of L-T4, 12 mg, once every 5 d x 3 of DT or the vehicle alone. Fetal plasma samples for Ep determinations were obtained before and at intervals after the start of the treatment. Retictulocyte and hematocrit levels, and the percent ...
