Validation of the disposable T-piece resuscitator (Neo-Tee): a bench study.

Objective: The Neo-Tee Infant T-piece resuscitator is a disposable T-piece resuscitator. The aim of this bench study was to assess the accuracy of the Neo-Tee using a measurement set-up and settings mimicking clinical practice.

Study Design: Nine Neo-Tee devices were tested using a face mask interface and a manikin.

D-amino acid aberrations in cerebrospinal fluid and plasma of smokers.

The glutamatergic neurotransmission system and the N-methyl-D-aspartate receptor (NMDAR) have been implicated in smoking and alcohol consumption behavior. Preclinical studies have demonstrated that nicotine and ethanol influence NMDAR functionality, which may have a role in tendencies to consume these substances. Nonetheless, little is known about concentrations of NMDAR coagonists in the cerebrospinal fluid (CSF) and plasma of individuals who smoke or consume alcohol.

Ex vivo changes in blood glucose levels seldom change blood glucose control algorithm recommendations.

Background: Hyperglycemia and glycemic variabilities are associated with adverse outcomes in critically ill patients. Blood glucose control with insulin mandates an adequate and precise assessment of blood glucose levels. Blood glucose levels, however, can change ex vivo after sampling.

Influence of rain, tidal wetting and relative humidity on release of carbon dioxide by standing-dead salt-marsh plants.

Dead parts of salt-marsh plants form a considerable fraction of their annual average standing crop. A microbial assemblage living on and in the standing-dead leaves and stems of Spartina alterniflora and Juncus roemerianus responds to saltwater, freshwater or water-vapor wetting by immediately beginning to release CO. Water-saturated, standing-dead leaves and culms of S.
