OBJECTIVES This study was undertaken to evaluate the effect of hyperbaric oxygen (HBO) on the repair of critical-sized defects in the presence and absence of a nonvascularized autogenous bone graft. STUDY DESIGN Ten New Zealand White rabbits were randomly divided into 2 groups of 5 animals each. Bilateral 15-mm calvarial defects were created in the parietal bones of each animal, resulting in ...

Background: Shorter hospitalisation after childbirth raises new challenges in the transition to parenthood. Aim. This paper reports a study designed to identify first-time mothers’ experience with The Neonatal Behavioral Observation System (NBO) as a guiding model. Method: A phenomenological qualitative study sampling four first-time mothers who received guidance from the NBO-specialist nurse t...

Stroke is a leading cause of death and disability due to disturbance of blood supply to the brain. As brain is highly sensitive to hypoxia, insufficient oxygen supply is a critical event contributing to ischemic brain injury. Normobaric hyperoxia (NBO) that aims to enhance oxygen delivery to hypoxic tissues has long been considered as a logical neuroprotective therapy for ischemic stroke. To da...

We analysed RXTE data of Sco X-1 which show kHz quasi-periodic oscillations (QPOs) and the ∼6–8 Hz normal-branch oscillation (NBO) simultaneously. Using power spectra of 0.03–0.5 s data segments, we find that both the upper kHz QPO frequency ν2 and the ratio of lower to upper kHz QPO amplitude are anticorrelated to variations in the X-ray count-rate taking place on the NBO time scale. The frequ...

OBJECTIVE To examine weight change trajectories among overweight and obese patients with binge eating disorder (BED) versus without (NBO) during the year prior to seeking treatment. METHODS Participants were 97 (75 women, 22 men) overweight and obese patients recruited for the same weight-loss treatment in primary care; 26 (27%) met DSM-5 BED criteria. Participants were assessed with the Eati...

Effect of in-water oxygen prebreathing at different depths on decompression-induced bubble formation and platelet activation in scuba divers was evaluated. Six volunteers participated in four diving protocols, with 2 wk of recovery between dives. On dive 1, before diving, all divers breathed normally for 20 min at the surface of the sea (Air). On dive 2, before diving, all divers breathed 100% ...

Normobaric hyperoxia (NBO) has been shown to be neuro- and vaso-protective during ischemic stroke. However, the underlying mechanisms remain to be fully elucidated. Activation of NADPH oxidase critically contributes to ischemic brain damage via increase in ROS production. We herein tested the hypothesis that NBO protects the blood-brain barrier (BBB) via inhibiting gp91phox (or called Nox2) con...

The structural aspects of xCs2O-(1-x)B2O3 glasses have been investigated by molecular dynamics as functions of Cs2O content (x=0.2, 0.3, and 0.4) and temperature (T=300 and 1250 K). The tetrahedral (BØ4-) and triangular (BØ3,BØ2O-, and BØO2 (2-)) short-range order borate units were found to be the structure-building entities of the simulated glasses [Ø=bridging oxygen (BO) and O-=nonbridging ox...

The presence of a salvageable penumbra, a region of ischemic brain tissue with sufficient energy for short-term survival, has been widely agreed as the premise for thrombolytic therapy with tissue plasminogen activator (tPA), which remains the only United States Food and Drug Administration (FDA) approved treatment for acute ischemia stroke. However, the use of tPA has been profoundly constrain...
