UNLABELLED The purpose of this study is to develop a method of quantitating the cerebral metabolic rate of glucose (CMRglc) by positron emission tomography using a population-based heated venous curve and one-point sampling from a non-heated vein, i.e. that can avoid arterial puncture. METHODS We conducted this study on 17 subjects with a mean age of 61 +/- 9 years. A time-concentration curve...

STUDY OBJECTIVES To evaluate the effects of humidification on nasal symptoms and compliance in sleep apnea patients using continuous positive airway pressure (CPAP). DESIGN A randomized, crossover design was employed. SETTING The study was conducted at two suburban community-based hospital sleep laboratories. PATIENTS Data were collected on 38 obstructive sleep apnea patients (mean age, 4...

IT MAY BE CONCLUDED THAT, UNDER THE CONDITIONS OF THE EXPERIMENTS: 1. The inhibiting action on homologous fibroblasts of the heated serum of a young animal increases relatively more than that of an old animal. After it has been heated, the inhibiting action of the serum of the old animal is still greater than that of the young animal. 2. The CO(2) precipitate obtained from the serum of a young ...

This paper investigates the suitability of a nickel chromium wire cutter (NCWC) for use on the GASPACS (Get Away Special Passive Attitude Control Satellite) Mission. It is intended that when activated the NCWC will cut through a restraining wire and thereby release the stored energy of the deployable AeroBoom. Flight worthiness is based on favorable performance during functional testing to addr...

BACKGROUND Minimizing total respiratory heat loss is an important goal during mechanical ventilation. The aim of the present study was to evaluate whether changes in tracheal temperature (a clinical parameter that is easy to measure) are reliable indices of total respiratory heat loss in mechanically ventilated patients. METHOD Total respiratory heat loss was measured, with three different me...

Background. Palm oil is commonly consumed in Asia. Repeatedly heating the oil is very common during food processing. Aim. This study is aimed to report on the risk of atherosclerosis due to the reheated oil consumption. Material and Methods. Twenty four male Sprague Dawley rats were divided into control, fresh-oil, 5 times heated-oil and 10 times heated-oil feeding groups. Heated palm oil was p...
