The objective of this study was to determine the antimicrobial activity of essential oils (EOs) extracted from Cinnamomum osmophloeum leaves and different tissues of Cryptomeria japonica against pathogenic Legionella pneumophila at 42 degrees C. Ten kinds of EOs were extracted by water distillation and their chemical constituents were quantified by gas(More)
BACKGROUND Caffeic acid phenethyl ester (CAPE) has been shown to protect the heart against ischemia/reperfusion (I/R) injury by various mechanisms including its antioxidant effect. In this study, we evaluated the protective effects of a CAPE analog with more structural stability in plasma, caffeic acid phenethyl amide (CAPA), on I/R injury in streptozotocin(More)
INTRODUCTION Mannitol was used in traumatic brain injury but controversy about the onset and duration. SETTING Clinical observational study. METHODS Fourteen traumatic brain injured patients with a Glasgow Coma Scale (GCS) score < or = 8 were enrolled. Group I patients (n = 8) with intracranial pressure (ICP) < 20 mmHg, and group II patients (n = 6)(More)
In recent years, lots of researches have explored how to extend the lifetime of wireless sensor networks. Many of them focus on how to defend against Denial of Service (DoS) [1] attacks, and focus on how to arrange the locations of sensor nodes in different wireless sensor network architectures to extend the lifetime of sensor networks and to improve(More)
Cinnamon oil extracted from leaves of Cinnamomum osmophloeum has recently been proved as a promising antibacterial agent against Legionella pneumophila, an etiological agent of human pneumonia known as Legionnaires' disease. However, the pH effects on the efficacy of cinnamon oil against L. pneumophila and its applicability to recreational spring water(More)
