PURPOSE Noninvasive frameless systems are increasingly being utilized for head immobilization in stereotactic radiosurgery (SRS). Knowing the head positioning reproducibility of frameless systems and their respective ability to limit intrafractional head motion is important in order to safely perform SRS. The purpose of this study was to evaluate and compare the intrafractional head motion of a...

BACKGROUND NT-proBNP measurements aid in the evaluation of patients with suspected heart failure (HF) and may facilitate risk stratification in patients with HF and acute coronary syndrome (ACS). Point-of-care (POC) assays may provide more timely results and potentially improve patient outcomes. METHODS We evaluated the analytical performance of the Response Biomedical Corporation whole blood...

We give a new proof of the result that Hankel operator Hf with bounded symbol is compact on standard weighted Fock spaces F2α(Cn) if and only H¯¯¯f compact. Our uses limit techniques extends to Fpα(Cn) when $1

n the past 2 decades, heart failure (HF) research has focused primarily on drugs and devices. In contrast, evidence remains scarce and mostly observational for dietary sodium restriction, 1–3 arguably the most widely recommended self-care measure for patients with HF. In recent studies, patients with HF consumed an average of 3600 to 4200 mg sodium daily by 24-hour urinary sodium excre-tion, 4 ...

Objective(s): Existing studies have demonstrated that intravenous and intramyocardial-administrated mesenchymal stem cells (MSCs) lead to tissue repair after cardiac disorders. We compared the efficiency of both administration methods.Materials and Methods: A rat model of isoproterenol-induced heart failure (ISO-HF) was established to co...

BACKGROUND Elevated body mass index (BMI; weight in kilograms divided by height in meters squared) in the obese range (> or =30 kg/m(2)) is associated with an excess risk of heart failure (HF). However, the impact of overweight or preobese (BMI, 25 to 29.9 kg/m(2)) status and physical activity on HF risk is unclear. METHODS AND RESULTS In a prospective cohort of 21,094 men (mean age, 53 years...

In this paper we report rovibrational energy levels, transition frequencies, and intensities computed for H 2 O-HF using a new ab initio potential surface compare with available experimental data. We use the rigid monomer approximation. A G 4 symmetry-adapted Lanczos algorithm an uncoupled product basis are employed. The levels up to J = . analytic 9-D is fit 39 771 counterpoise corrected CCSD(...

nowadays nmr spectroscopy becomes a powerful tool in chemistry because of the nmr chemical shifts. hartree–fock theory and the gauge-including atomic orbital (giao) methods are used in the calculation of 29si nmr chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. calculations have been performed at geo...
