Needle aspiration versus intercostal tube drainage for pneumothorax in the newborn.
Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It may be treated with either needle aspiration or insertion of a chest tube. The former consists of aspiration of air with a syringe through a needle or an angiocatheter, usually through the second or third intercostal space in the midclavicular line.
Carbonate formation on p(4 x 4)-O/Ag(111)
High-resolution core-level spectroscopy and density-functional theory calculations have been used to investigate CO adsorption on the p(4 x 4) structure of oxidized Ag(111). CO adsorption with subsequent carbonate formation was observed at 100 K. The experimental results are consistent with calculations that reveal low activation barriers to form CO2 and CO32- from adsorbed CO. On the basis of a g
Comparing wine-based and beer-based baits for moth trapping: a field experiment
Vid fångst av nattfjärilar använder man ofta lockbeten. De består av en trasa eller liknande som dränks in med någon lockande vätska och hängs upp i t.ex. ett träd. Under natten kan betet inspekteras många gånger och djur samlas in. Recepten för den lockande vätska varierar kraftigt mellan olika samlare men innehåller alltid jästa produkter av något slag. En stor skiljelinje går mellan beten som b
Hyperglycemia-induced downregulation of apolipoprotein M expression is not via the hexosamine pathway.
We previously demonstrated that hyperglycemia could suppress apolipoprotein M (apoM) synthesis both in vivo and in vitro; however, the mechanism of hyperglycemia-induced downregulation of apoM expression is unknown yet.

Parity independence of the zero-bias conductance peak in a nanowire based topological superconductor-quantum dot hybrid device.
We explore the signatures of Majorana fermions in a nanowire based topological superconductor-quantum dot-topological superconductor hybrid device by charge transport measurements. At zero magnetic field, well-defined Coulomb diamonds and the Kondo effect are observed. Under the application of a finite, sufficiently strong magnetic field, a zero-bias conductance peak structure is observed. It is f

Costs and outcomes of an exercise referral programme - A 1-year follow-up study.
Aims: To analyse, at a one year follow up, cost offset and outcomes of changing the physical activity (PA) behaviour due to a primary care intervention. Methodology: Participants were 528 inactive individuals with life-style related health problems, 18-84 years, and randomised into a high-dose intervention group (n=270) or a low-dose intervention group (n=258). The four month lasting intervention
The challenges of integrating oxidative stress into life history biology.
It has been proposed that the molecular and physiological systems that regulate biological functions impose costs and constraints that are fundamental to the understanding of variation in life histories. In particular, studies of oxidative stress emphasize how evolutionary contingency can impose novel trade-offs for organisms, and how this may create or eliminate functional linkages between traits
Oxy-fuel Combustion of Ethanol in Premixed Flames
First measurements of the adiabatic laminar burning velocities of lean ethanol + oxygen + carbon dioxide flames, at 1 atm and initial gas mixture temperatures of 298, 318, and 338 K, are presented. The oxygen content O-2/(O-2 + CO2) in the artificial air was 35%. The laminar burning velocities were determined using the heat flux method, where a non-stretched flame is stabilized under adiabatic con
Quality of life in people with diabetes: a systematic review of studies in Iran.
Evaluation of health-related quality of life (HRQoL) among people with diabetes has been growing in Iran over the last decade. The main aim of the current study was to systematically review the characteristics of these studies and examine quality of their findings. Persian (SID, Magiran) and English (Pubmed, Medline, Web of Science, CINAHL, Scopus, PsycINFO and ERIC) databases were systematically

RipleyGUI: software for analyzing spatial patterns in 3D cell distributions.
The true revolution in the age of digital neuroanatomy is the ability to extensively quantify anatomical structures and thus investigate structure-function relationships in great detail. To facilitate the quantification of neuronal cell patterns we have developed RipleyGUI, a MATLAB-based software that can be used to detect patterns in the 3D distribution of cells. RipleyGUI uses Ripley's K-functi
Comparing Hall Effect and Field Effect Measurements on the Same Single Nanowire
We compare and discuss the two most commonly used electrical characterization techniques for nanowires (NWs). In a novel single-NW device, we combine Hall effect and back-gated and top-gated field effect measurements and quantify the carrier concentrations in a series of sulfur-doped InP NWs. The carrier concentrations from Hall effect and field effect measurements are found to correlate well when

Automated Decision Support for Bone Scintigraphy
A quantitative analysis of metastatic bone involvement can be an important prognostic indicator of survival or a tool in monitoring treatment response in patients with cancer The purpose of this study was to develop a completely automated decision support system for whole-body bone scans using image analysis and artificial neural networks. The study population consisted of 795 whole-body bone scan

Biomimetic and Microbial Approaches to Solar Fuel Generation
Photosynthesis is performed by a multitude of organisms, but in P nearly all cases, it is variations on a common theme: absorption of light followed by energy transfer to a reaction center where charge separation takes place, This initial form of chemical energy is stabilized by the biosynthesis of carbohydrates. To produce these energy-rich products, a substrate is needed that feeds in reductive
