OBJECTIVE: We had previously experienced a case involving prolonged cardiopulmonary resuscitation (CPR) on Mt. Fuji (3776 m), demanding strenuous work by the rescuers. The objective of this study was to compare the effect of compression-only and conventional CPR on oxygen saturation of rescuers in a hypoxemic environment. METHODS: Changes in percutaneous arterial oxygen saturation (SpO2) and heart rate during CPR action were measured in a hypobaric chamber with barometric pressure adjusted to be equivalent to 3700 m above sea level (630-640 hPa)...

This study's objective was to determine if nutrient restriction during late gestation affected beef heifer feed intake, body weight (BW) gain and endocrine regulation during a 10-week feeding trial. During the last 100 days of gestation, control (CON) dams were fed to increase body condition score (BCS). Whereas, nutrient-restricted dams (NR) and NR dams protein supplemented 3 days/week (NRS) were fed to decrease BCS by 1.2. After parturition, all cow-calf pairs were moved to a common pasture and fed in excess of requirements until weaning...

J Britton
BACKGROUND: Dermatology laser treatments are undertaken at regional departments using lasers of different powers and wavelengths. In order to achieve good outcomes there need to be good consistency of laser output across different weeks as it is custom and practice to break down the treatments into individual fractions. Departments will also collect information from test patches to help decide on the most appropriate treatment parameters for individual patients. OBJECTIVES: The objective of these experiments is to assess the variability of the energy outputs from a small number of lasers across multiple weeks at realistic parameters...

Mesenchymal stem cells (MSCs) have received considerable attention in regenerative medicine, particularly in light of prospects for targeted delivery by intra-arterial injection. However, little is known about the mechanics of MSC sequestration in the microvasculature and the yield pressure (PY), above which MSCs will pass through microvessels of a given diameter. The objectives of the current study were to delineate the dependency of PY on cell size and the heterogeneity of cell mechanical properties and diameters (DCELL) of cultured MSCs...

#7
Vivian Holten, Paul R MacNeilage
Optic flow patterns generated by self-motion relative to the stationary environment result in congruent visual-vestibular self-motion signals. Incongruent signals can arise due to object motion, vestibular dysfunction, or artificial stimulation, which are less common. Hence, we are predominantly exposed to congruent rather than incongruent visual-vestibular stimulation. If the brain takes advantage of this probabilistic association, we expect observers to be more sensitive to visual optic flow that is congruent with ongoing vestibular stimulation...

Active cysteinyl protease Caspase-6 is associated with early Alzheimer and Huntington diseases. Higher entorhinal cortex and hippocampal Caspase-6 levels correlate with lower cognitive performance in aged humans. Caspase-6 induces axonal degeneration in human primary neuron cultures and causes inflammation and neurodegeneration in mouse hippocampus, and age-dependent memory impairment. To assess whether Caspase-6 causes damage to another neuronal system, a transgenic knock-in mouse overexpressing a self-activated form of Caspase-6 five-fold in the striatum, the area affected in Huntington disease, and 2...

Graduate teaching assistants (GTAs) play important instructional roles in introductory science courses, yet they often have little training in pedagogy. The most common form of teaching professional development (PD) for GTAs is a presemester workshop held at the course, department, or college level. In this study, we compare the effectiveness of presemester workshops at three northeastern research universities, each of which incorporated scientific teaching as the pedagogical content framework. The comparison of GTA PD program outcomes at three different institutions is intended to test theoretical assertions about the key role of contextual factors in GTA PD efficacy...

BACKGROUND: Insulin dysregulation (ID) with basal or postprandial hyperinsulinemia is one of the key findings in horses and ponies suffering from the equine metabolic syndrome (EMS). Assessment of ID can easily be performed in clinical settings by the use of oral glucose challenge tests. Oral glucose test (OGT) performed with 1 g/kg bodyweight (BW) glucose administered via naso-gastric tube allows the exact administration of a defined glucose dosage in a short time. However, reliable cut-off values have not been available so far...

The purpose of the present study is to compare results from the 12-item General Functioning Scale (GF-FAD) of the Family Assessment Device (FAD) to a three-item version, the Brief Assessment of Family Functioning Scale (BAFFS), designed to be used when brevity is especially important. We used principal components analysis of the GF-FAD, followed by multiple sample confirmatory factor analyses to test the robustness of the BAFFS in different samples. The BAFFS correlated highly with the GF-FAD, and demonstrated good concurrent validity with another measure of global marital functioning, the Dyadic Adjustment Scale-4 in a help-seeking sample...
