Evaluation of Left Ventricular Volumes by Real-Time 3-Dimensional Echocardiography

Quantitative measurements of left ventricular volume and ejection fraction are useful in the management of patients with heart disease. Several imaging methods exist, but are limited by cost, invasiveness, or exposure to radio-isotopes. Conventional echocardiography is a noninvasive method that allows estimation of left ventricular size and function; however, quantitative measurements of volume are not widely used due to lack of reproducibility and inaccurate measurements. ...

This study was an update and amplification of exposure measurements of the EPIC-Potsdam Study, which started in 1994-1998.

Comparison of On-line and Off-line Measurements of Exhaled Nitric Oxide (NO)

Asthma is a major health problem worldwide. The measurement of fractional exhaled nitric oxide (FENO) has been established as a valuable non invasive and simple tool in the diagnosis of asthma and may also act as a useful surrogate inflammatory marker on which to base treatment decisions in asthma management algorithms. The measurement is useful also in other respiratory diseases. Current methods of measuring FENO include on line measurements by heavy duty expensive analyzers w...

Salivary Antioxidant Capacity Before and After Complete Dental Rehabilitation

Salivary samples were obtained from 20 children in their fifth year of life diagnosed S-ECC and 20 age and sex matched controls. Complete dental rehabilitation under general anesthesia was performed for the 20 children with S-ECC, and follow up salivary samples were obtained one week and three months post operatively. The TAC was measured using a commercially available Oxygen Radical Absorbance Antioxidant Assay measurement kit (Zen-Bio ORAC™, AMS Biotechnology, Abington UK).

The Effect of Frequent Self Measurements of Blood Pressure on the Control of Hypertension

Despite knowledge regarding the importance of controlling patients' blood pressure (BP) only 30% of treated patients achieve BP goals. Our objective was to determine the effect of frequent self measurements of BP in the patients' natural environment as a mean to improve BP control. Our hypothesis was that frequent measurements of BP will reduce mean BP levels.
