OBJECTIVES The authors performed a meta-analysis to evaluate whether levosimendan is associated with improved survival in patients undergoing cardiac surgery. DESIGN A meta-analysis. SETTING Hospitals. PARTICIPANTS A total of 440 patients from 10 randomized controlled studies were included in the analysis. INTERVENTIONS None. MEASURMENTS AND MAIN RESULTS: Four investigators independentl...

Recent data obtained from Rana temporaria sartorius muscles during an isometric tetanus indicate that the time-course of phosphocreatine (PC) splitting cannot account for the total energy (heat + work) liberation (Gilbert et al. 1971. J. Physiol. (Lond.) 218:)63). As this conclusion is important to an understanding of the chemical energetics of contraction, similar experments were performed on ...

ANDI (Aberration of normal development and involution) classification covers most of the benign breast conditions as a result of hormonal influence. Prolactin plays an important role in normal proliferation and differentiation of breast epithelium. The objective of this hospital based study was to find out clinical presentation and prolactin level of ANDI patients. Total 330 patients with diffe...

Hydroperoxide lyase (HPOOH lyase) was extracted from tomato leaves (Lycopersicon esculentum Mill.) and purified to apparent homogeneity by fractionated precipitation with polyethylene glycol 6000, ion exchange chromatography, and ultrafiltration. The enzyme is a trimer of 73 000 Da units with a molecular mass of 216 000 (determined by native-PAGE and gel filtration); its pI is around 4.9. Enzym...

We present carbon and strontium abundances for 100 metal-poor stars measured from R∼7000 spectra obtained with the Echellette Spectrograph and Imager at the Keck Observatory. Using spectral synthesis of the G-band region, we have derived carbon abundances for stars ranging from [Fe/H]= −1.3 to [Fe/H]= −3.8. The formal errors are ∼ 0.2 dex in [C/Fe]. The strontium abundance in these stars was me...

We present new measurments of the gas-phase C/O abundance ratio in both the NW and SE components of the extremely metal-poor dwarf irregular galaxy I Zw 18, based on ultraviolet spectroscopy of the two H II regions using the Faint Object Spectrograph on the Hubble Space Telescope. We determine values of log C/O = −0.63±0.10 for the NW component and log C/O = −0.56±0.09 for the SE component. In ...

In this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(BB) and Tropaeolin O(TO) in food samples using cloud point extraction (CPE) prior to spectrophotometric determination. The effects of main factors such as pH, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...

SUMMARY In a cross-sectional survey, the nutritionql status [on the basis of weight(Wt), height(Ht), body mass index(BMI) and mid-arm circumferences (MAC)] of 45 I women attending the health centers in Zabol city was investigated. The results showed that 14.4% of women were underweight and 2.2% stunted. On the basis of BMI 36.4% of women had wasting and 18.8% overweight. Also, 31.8% had amid-a...

pollen grains of five olive cultivars (olea europaea l .) were examined, using scanning electron microscopy (sem) for identification purposes. four measurments, polar axis (p), equatorial diameter (e), p/e ratio and exine patterns were made. forty pollen grains of each cultivar were viewed before finally selecting a representative pollen grain. polar diameter ranged between 22.76 μm for the...

According to Patrick Colm Hogan, in the US academic context, few people in literary theory or comparative literature have much familiarity with non-Western literary theories, and fewer still have research expertise in the field. While working on a project in non-Western literary theory, he was surprised to find that many of his friends and colleagues found it difficult to understand what non-We...
