BACKGROUND/AIMS The purpose of the study was to investigate the efficacy of plaque removal by 2 different toothbrushes in a laboratory model and in a clinical study. METHOD The 2 brushes used were the Philips/Jordan HP 735 and the Braun Oral-B Ultra Plaque Remover (D9). Both were compared in a laboratory study (using a robot system) and a short-term clinical study. For the laboratory study, p...

Methods 30 patients (21 male, 9 female; median age 69.5 years) with diagnosis of TTR amyloidosis (wild-type n=13, hereditary n=17) were evaluated by cardiac MRI (CMR; Achieva Intera Philips Medical Systems, Best, The Netherlands), and Technetium-DPD scintigraphy. EDV, ESV, EF and myocardial mass were analyzed on a standard workstation (Philips Viewforum). Longitudinal function was assessed by m...

Demand variability increases as one moves up a supply chain. The demand for finished products is less variable than for subassemblies, which is less variable than for individual components. This phenomenon is known as the bullwhip or Forrester effect. It increases inventory unnecessarily and makes managing the capacity of equipment and personnel difficult. In 1999, Philips Semiconductors confir...

The coating of thin films on substrates remains an important activity for Philips’ products, like displays, electronic devices and storage media. A characteristic of these products is that they display topographies, or chemical heterogeneities. We are therefore interested in understanding the formation of coating layers from liquid phase on such substrates. This work concentrates on geometric t...

Electrocardiogram (ECG) databases play an important role in medical research, pharmaceutical research, medical education and health care. Due to growing demands in research, training, and health care, designing and managing such ECG databases has become a complex problem. This paper reports on the new design approach and the new application model of the Philips ECG Management System (EMS). The ...

OBJECTIVES This study assessed the ability of live/real time three-dimensional transesophageal echocardiography (3DTEE) in measuring (1) atrial septal defect (ASD) maximum dimension, area, and adjacent rim size, (2) ASD occluder left and right atrial disk size, (3) length of contact between the left atrial (LA) disk and the aorta, and in (4) assessing device related complications such as residu...
