Purpose: The aim of this study is to analyze the utility lipid parameters individually and low-density lipoprotein cholesterol/high-density cholesterol (LDL-C/HDL-C) ratio as a possible risk marker for intracerebral hemorrhages (ICH).
 Materials Methods: This was multicenter, retrospective case-control that included 226 patients with ICH controls. Lipid were evaluated after 12 h fasting in...

INTRODUCTION C/C composites have been used for aerospace application due to their excellent properties such as low density, high heat resistance in inert gas atmosphere, high specific strength and etc. Since C/C composites have relatively higher fracture resistance than other CMCs, this material can also be used as structural components with high reliability. The fatigue properties are also imp...

We report on the application of a compact and field-deployable instrument, based on a continuous-wave fiber-coupled Telecom external cavity diode laser, to measure the C/C isotope ratio in CO2 from a wood-based combustion. Carbon dioxide, the most important greenhouse gas, is a major product of combustion. The measurements of the C/C isotopic ratio in CO2 from combustion emission permit one to ...

The astrophysical origins of ∼3 nm-diameter meteoritic nanodiamonds can be inferred from the ratio of C/ C 12 13 . It is essential to achieve high spatial and mass resolving power and minimize all sources of signal loss in order to obtain statistically significant measurements. We conducted atom-probe tomography on meteoritic nanodiamonds embedded between layers of Pt. We describe sample prepar...

The 12 C/ 13 C ratio has been measured in a sample of 10 carbon stars with high mass-loss rates, of ≥ 10 −5 M yr −1. This sample is complete for northern hemisphere carbon stars within ∼ 1 kpc of the Sun. Using the J=2–1 rotational lines of CO and 13 CO, the intensity ratio of 12 CO/ 13 CO is found to be 17 ± 11 for the sample, and the deduced 12 C/ 13 C abundance ratio, after corrections for C...

Supported vanadia catalyst was successfully synthesized using wet impregnation of gamma-Alumina to study Propane Oxidative Dehydrogenation (POD). The prepared catalysts were characterized with XRD, BET, and TPR tests. In a broad temperature range (340 to 630°C), effects of vanadia loading (2.7, 5.4, and 9 wt%) and propane to oxygen ratio (3/1 to 1/3) were investigated on propane conversion as w...

This study aimed to produce omega-3-emriched broiler meat by using ultrasonicated flaxseed oil nanoemulsions coated with whey protein-sodium alginate. Three hundred 1-d-old (Ross, 308) male broiler chicks were allocated randomly to 5 experimental treatments with 4 replicate pens. Experimental treatments included basal diet (BD), basal diet plus flaxseed oil (BD+FO, 1 mL/kg/BW), basal diet plus ...

the association between overt hypothyroidism and altered lipid profile is well known, whereas the significance of dyslipidemia in subclinical hypothyroidism (sch) is still a matter of debate. the aim of the present study was to evaluate the lipid profile in patients with sch in comparison to controls. serum lipid parameters of 34 patients with sch and 34 age- and sex-matched healthy controls we...
