STUDY OBJECTIVES To ascertain whether inspiratory pressure support (IPS) can be triggered reliably from and targeted at esophageal pressures (Pes), and to compare the work of breathing and time delay to initiation of inspiratory flow between conventional pressure support and esophageal-directed pressure support (EDPS). DESIGN Prospective laboratory study. SETTING University medical school. ...

The Korean prostrate spurge Euphorbia supina is abundant in polyphenols and has been used as a folk medicine in Korea against a variety of diseases. Thus, we aimed to investigate the effect of polyphenol mixtures of Korean Euphorbia supina (PES) on the invasion and metastasis of highly metastatic breast cancer MDA-MB-231 cells. Firstly, PES showed no cytotoxicity on cancer cells and endothelial...

OBJECTIVE A measure of play experience in video games was developed through literature review and two empirical validation studies. BACKGROUND Despite the considerable attention given to games in the behavioral sciences, play experience remains empirically underexamined. One reason for this gap is the absence of a scale that measures play experience. METHOD In Study 1, the initial Play Expe...

UNLABELLED The objective was to evaluate supplementation of fetal calf serum (FCS) and phenazine ethosulfate (PES), a metabolic regulator that inhibits fatty acid synthesis, in culture media during in vitro production (IVP) of bovine embryos. Taking oocyte fertilization (n = 4,320) as Day 0, four concentrations of FCS (0, 2.5, 5, and 10%) and three periods of exposure to PES (without addition-C...

AIM To compare anterior pituitary functions between subjects with total and partial primary empty sella (PES) and to assess whether all cases with PES need endocrinological evaluation. MATERIAL AND METHODS Eighty-one subjects with PES (34 total and 47 partial) were included in the study. Basal anterior pituitary and its target hormones were assessed and those with low insulin like growth fact...

Peripheral electrical stimulation (PES) has been utilized to manage chronic pain associated with nerve injury. However, the data on clinical effectiveness are conflicting and the neurophysiological mechanism is not well known. This study was designed to assess whether PES relieved neuropathic pain and its possible mechanisms. The neuropathic pain model was made with lumbar 5th (L5) and 6th (L6)...

Daniel Abramovitch Hewlett-Packard Laboratories 1501 Page Mill Road, M/S 2U-10 Palo Alto, CA 94304 Abstract– This paper describes the PES Pareto Method, a useful tool for identifying and eliminating key contributors to uncertainty in the Position Error Signal (PES) of a magnetic disk drive[1, 2, 3]. Once identified and ranked according to their overall effect on PES, the top–ranking sources can...
