Mitochondrial respiration in human viable platelets-Methodology and influence of gender, age and storage.
Studying whole cell preparations with intact mitochondria and respiratory complexes has a clear benefit compared to isolated or disrupted mitochondria due to the dynamic interplay between mitochondria and other cellular compartments. Platelet mitochondria have a potential to serve as a source of human viable mitochondria when studying mitochondrial physiology and pathogenic mechanisms, as well as
Express yourself: bold individuals induce enhanced morphological defences.
Organisms display an impressive array of defence strategies in nature. Inducible defences (changes in morphology and/or behaviour within a prey's lifetime) allow prey to decrease vulnerability to predators and avoid unnecessary costs of expression. Many studies report considerable interindividual variation in the degree to which inducible defences are expressed, yet what underlies this variation i
Molecular microheterogeneity of prostate specific antigen in seminal fluid by mass spectrometry.
OBJECTIVES: Prostate specific antigen (PSA) is a widely used and clinically valuable marker for prostate disease. In order to enable the development of new PSA assays and progress the understanding of the biology of PSA we have analyzed PSA in seminal plasma. Design and methods PSA in seminal plasma from men attending a fertility clinic and healthy controls was analyzed using SDS-PAGE, Western blo
Atherosclerosis aggravates ischemia/reperfusion injury in the gut and remote damage in the liver and the lung
Objective We investigated whether mesenteric ischemia/reperfusion (I/R)-associated gut injury and remote liver and lung damage are affected by prevalent atherosclerosis. Methods Mesenteric ischemia was induced in atherosclerotic ApoE-deficient (ApoE(-/-)) and control C57BL/6 mice by clamping the superior mesenteric artery for 30 min. Mesenteric microcirculatory dysfunction and leukocytic inflammat
The work experience measurement scale (WEMS): A useful tool in workplace health promotion.
OBJECTIVE: To present validity data for the Work Experience Measurement Scale (WEMS), an instrument measuring multifaceted work experience from a salutogenic health resource perspective as a contrast to the more common pathogenic risk perspective, by exploring WEMS relationship to established measurements that are positively related to health and work. A salutogenic perspective focuses on finding
Blood pressure and low-density lipoprotein-cholesterol lowering for prevention of strokes and cognitive decline: a review of available trial evidence.
It is well established by a large number of randomized controlled trials that lowering blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) by drugs are powerful means to reduce stroke incidence, but the optimal BP and LDL-C levels to be achieved are largely uncertain. Concerning BP targets, two hypotheses are being confronted: first, the lower the BP, the better the treatment outco
Betatron emission as a diagnostic for injection and acceleration mechanisms in laser plasma accelerators
Betatron x-ray emission in laser plasma accelerators is a promising compact source that may be an alternative to conventional x-ray sources, based on large scale machines. In addition to its potential as a source, precise measurements of betatron emission can reveal crucial information about relativistic laser-plasma interaction. We show that the emission length and the position of the x-ray emiss
Changes in human fetal oxygenation during maternal hyperoxia as estimated by BOLD MRI
Objective Changes in blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) signal are closely related to changes in fetal oxygenation. In this study, we aimed to investigate the changes in human fetal oxygenation during maternal hyperoxia by using the non-invasive BOLD MRI technique. Method Eight healthy pregnant women in gestational week 28 to 34 were included. With the use of a fa
Optimizing the trade-off between offspring number and quality in unpredictable environments: Testing the role of differential androgen transfer to collared flycatcher eggs
According to the brood reduction hypothesis, parents adjust their brood size in response to current environmental conditions. When resources are abundant, parents can successfully raise all hatched offspring, but when resources are scarce, brood reduction, i.e., the sacrifice of some siblings to secure the quality of a subset of offspring, may maximize fitness. Differential transfer of maternal an
Detection Of Gas Concentration By Correlation Spectroscopy Using A Multi-Wavelength Fiber Laser
A correlation spectroscopy (COSPEC) based on a multi-wavelength fiber laser is first proposed for the detection of gas concentration. The lasing wavelengths are selected to match several characteristic absorption peaks of the gas under test, and the gas concentration is easily measured by correlating it with the reference gas. The present method is immune from the instability of the light source a
Revisiting 'Weinberg's Choice': Classic Tensions in the Concept of Scientific Merit
Alvin Weinberg's classic and much debated two articles in Minerva, "Criteria for Scientific Choice" (1963) and "Criteria for Scientific Choice II - The Two Cultures" (1964), represent two of the first and most important attempts to create a meta-discourse about priority setting in science policy, and many of the points advanced remain relevant. The goal of this paper is to elaborate on the relevan
Association between the ABCC11 gene polymorphism and the expression of apolipoprotein D by the apocrine glands in axillary osmidrosis.
It has been suggested that the adenosine triphosphate‑binding cassette sub‑family C member 11 (ABCC11) gene polymorphism and apolipoprotein D (ApoD), an odor precursor carrier, may be important in the formation of axillary odor. To date, few studies have examined the potential correlation between these two factors. The present study aimed to investigate the association between a 538 G>A single‑nuc
Time-lapse electrical resistivity tomography of a water infiltration test on Johannishus Esker, Sweden
Managed aquifer recharge (MAR) is an efficient way to remove organic matter from raw water and, at the same time, reduce temperature variation. Two MAR sites were constructed by Karlskrona municipality on Johannishus Esker in Sweden. One of these sites, Vång, was monitored for electrical conductivity and electrical resistivity (using electrical resistivity tomography - ERT) during a 9-week tracer
Random walk with barycentric self-interaction
Biased motion and molecular motor properties of bipedal spiders
Molecular spiders are synthetic molecular motors featuring multiple legs that each can interact with a substrate through binding and cleavage. Experimental studies suggest the motion of the spider in a matrix is biased toward uncleaved substrates and that spider properties such as processivity can be altered by changing the binding strength of the legs to substrate [R. Pei, S. K. Taylor, D. Stefan
No association between educational level and pancreatic cancer incidence in the European Prospective Investigation into Cancer and Nutrition
Introduction: Until now, studies examining the relationship between socioeconomic status and pancreatic cancer incidence have been inconclusive. Aim: To prospectively investigate to what extent pancreatic cancer incidence varies according to educational level within the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: In the EPIC study, socioeconomic status at ba
Up-Regulation of G-Protein-Coupled Receptors for Endothelin and Thromboxane by Lipid-Soluble Smoke Particles in Renal Artery of Rat
Up-regulation of G-protein-coupled receptors (GPCR) plays key roles in renal hypertension and cardiovascular disease pathogenesis. The present study was designed to examine if lipid-soluble cigarette smoking particles (DSP), nicotine and endotoxin (LPS), induce GPCR up-regulation for thromboxane A(2) (TP), endothelin type A (ETA) and type B (ETB) receptors in renal artery, and if intracellular sig
Effect of climate change on the potential spread of the Colorado potato beetle in Scandinavia : an ensemble approach
Medical education in Sweden.
Undergraduate medical education in Sweden has moved from nationally regulated, subject-based courses to programmes integrated either around organ systems or physiological and patho-physiological processes, or organised around basic medical science in conjunction with clinical specialities, with individual profiles at the seven medical schools. The national regulations are restricted to overall aca
