A radial velocity (RV) survey to detect central stars in binary systems was carried out between 2002 and 2004. [5] reported that 10 out of 11 monitored stars exhibited strong RV variability, but periods were not detected. Since other mechanisms, such as wind variability, can cause apparent RV variations, we monitored 4 of the 10 RV-variable stars at echelle resolutions to determine the origin o...

BACKGROUND In advanced gastric cancer, the relationship between tumor response and prognosis is far from clear. METHODS We performed a pooled analysis on published data from 4593 patients in 25 randomized trials of first-line chemotherapy for advanced gastric cancer. A weighed analysis was used to investigate the correlation between objective response rate (RR) and time to progression (TTP) a...

A new regenerator matrix design that improves the efficiency of a Stirling engine has been developed in a numerical study of the existing SM5 Stirling engine. A new, detailed, one-dimensional Stirling engine model that delivers results in good agreement with experimental data was used for mapping the performance of the engine, for mapping the effects of regenerator matrix temperature oscillatio...

Hypoxanthine phosphoribosyltransferase (HPRT, IMP:pyrophosphate phosphoribosyltransferase, EC 2.4.2.8) can be purified 5-to 10,000-fold from extracts of HeLa (human) cells by a three-step procedure consisting of high-speed centrifugation, adsorption to Sepharose-conjugated HPRT antibody, and sodium dodecyl sulfate/polyacrylamide gel electrophoresis. Purified enzyme labeled in vivo with radioact...

Sadness is a common symptom in the general population. We tested hypothesis that sadness an intermediate state on continuum from well-being to major depressive disorder (MDD). Using data The National Epidemiologic Study of Alcohol and Related Conditions III (NESARC-III), large representative US population sample, we assessed prevalence sadness, its sociodemographic clinical correlates, using th...

Abstract Introduction Malnutrition is a key priority on the global health agenda, yet impact of nutritional state cancer surgery across income strata remains poorly described. This study aimed to determine effect malnutrition early postoperative outcomes following elective for colorectal or gastric cancer. Method Multicentre, international prospective cohort consecutive patients undergoing was ...

In the murine brain, the first post-mitotic cortical neurons formed during embryogenesis express store-operated channels (SOCs) sensitive to Pyr3, initially proposed as a blocker of the transient receptor potential channel of C type 3 (TRPC3 channel). However, Pyr3 does not discriminate between Orai and TRPC3 channels, questioning the contribution of TRPC3 in SOCs. This study was undertaken to ...

Radio variability in some radio-quiet (RQ) active galactic nuclei suggests emission from regions close to the central engine, possibly outer accretion disc corona. If origins of radio and X-ray are physically related, their may be temporarily correlated, with time delays. We present results quasi-simultaneous monitoring three RQ Seyfert galaxies, Mrk 110, 766, NGC 4593, carried out Very Large A...

INTRODUCTION Specific inspiratory muscle training (IMT) has been shown to significantly attenuate the fall in arterial oxygen saturation (SpO2) during exhaustive exercise while breathing a hypoxic gas mixture of 14% oxygen. The aim of the current study was to assess the impact of IMT on resting SpO2 over a range of altitudes in healthy individuals. METHODS Resting SpO2 and the Borg Score were...

INTRODUCTION To identify risk factors for early (< three days) intensive care unit (ICU) admission of patients hospitalised with community-acquired pneumonia (CAP) and not requiring immediate ICU admission, and to stratify the risk of ICU admission on days 1 to 3. METHODS Using the original data from four North American and European prospective multicentre cohort studies of patients with CAP,...
