Physiological changes due to aging are intensively studied as they have far-reaching implications for the mechanistic and evolutionary theories of senescence. In this respect, metabolic rate has been suggested to play a role for the deterioration and damage of cells and tissues with age, partly due to the generation of reactive oxygen species. To mitigate such damage, individuals can be predicted

The fatty acid specificity of five lipases towards eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was evaluated in the hydrolysis of fish oil, squid oil and a model system. The model system contained methyl esters of EPA, DHA and palmitic acid. All the investigated lipases discriminated against both EPA and DHA more in the model system than in the natural oils. Thus both EPA and DHA we

After severe acquired brain injury some patients develop a prolonged disorder of consciousness (vegetative state or minimally conscious state), and as such cannot actively participate in neurorehabilitation. However, international opinion and recent research developments emphasize the need for involvement of rehabilitation medicine units in the care of these patients. The article presents recommen

Stable walking depends on the coordination of multiple biomechanical degrees of freedom to ensure the dynamic maintenance of whole-body equilibrium as well as continuous forward progression. We investigated adult age-related differences in whole-body coordination underlying stabilization of center of mass (CoM) position and step pattern during locomotion. Sixteen younger (20-30 years) and 16 healt

Pulsating flow through bifurcations are of general interest. In the human body such flows are also very common; for example in blood vessels and the respiratory tract. The characteristics of the flow in arteries have been related to the process of atherogenesis, based on the observation that the initial manifestation of the process is observed at certain common locations, i.e., near bifurcations i

Popular Abstract in Swedish Skador på skelettet kan uppstå efter bl.a. olyckor, tumörkirurgi eller strålning. Ofta är sådana skador mycket handikappande då de påverkar kroppens funktion, stabilitet och utseende. Om benvävnad saknas eller måste bytas ut använder man sig idag av mikrokirurgiska metoder, där man flyttar kroppseget ben från ett ställe till ett annat. Tyvärr innebär detta att man skapaBone deficiencies, caused by malformations, trauma or adverse effects from medical treatments, are a clinical challenge and often associated with reduced physical function and quality of life. Autologeous bone grafts can be used to reconstruct skeletal defects, but the right size and quality of bone might not always be available and even so, donor-site morbidity might follow. A pre-fabricated or t

We prove a strong comparison theorem in the class ${\cal E}_p(\Omega)$ of certain plurisubharmonic functions with infinite total complex Monge-Amp\`ere masses. We also obtain a convergence theorem in ${\cal E}_p(\Omega)$

L-2,L-3-edge X-ray absorption spectroscopy (XAS) has demonstrated unique capabilities for the analysis of the electronic structure of di-Ru complexes such as the blue dimer cis,cis-[(Ru2O)-O-III(H2O)(2)(bpy)(4)](4+) water oxidation catalyst. Spectra of the blue dimer and the monomeric [Ru(NH3)(6)](3+) model complex show considerably different splitting of the Ru L-2,L-3 absorption edge, which refl

Lean premixed flame characteristics of several typical low calorific value (LCV) syngases (basis CO/H-2/CH4/CO2/N-2), including bituminous coal, wood residue, corn core, and wheat straw gasification syngas, were investigated using OH planar laser induced fluorescence (PLIF) technology. OH radical distributions within the turbulent flame were measured for different turbulence intensities. Flame str

Simulation of atmospheric and surface processes with an atmospheric model (RAMS) during a period of ten days in August 2001 over a boreal area in Sweden were compared to tower measurements and aircraft measurements of vertical profiles as well as surface fluxes from low altitude flights. The shape of the vertical profiles was simulated reasonably well by the model although there were significant b

Oat, (Avena sativa) is an excellent source of mixed linkage beta-glucans ((1 -> 3)(1 -> 4)-beta-D-glucan), a dietary fibre with cholesterol lowering properties. Using a mutagenized oat-population we screened 1700 different lines and identified ten lines that displayed beta-glucan levels above 6.7% and 10 below 3.6%. The extreme values were 1.8% and 7.5%. We chose six lines with an increased- and f

We present a flexible and compact experimental setup that combines an in vacuum liquid jet with an x-ray emission spectrometer to enable static and femtosecond time-resolved resonant inelastic soft x-ray scattering (RIXS) measurements from liquids at free electron laser (FEL) light sources. We demonstrate the feasibility of this type of experiments with the measurements performed at the Linac Cohe

Objective. Between one-third and half of all radiology examinations worldwide are probably chest studies. The aim of the current study was to retrospectively evaluate the clinical influence of chest radiography. Methods. In a tertiary referral hospital, 939 consecutive daytime chest radiography examinations were evaluated. The outcome was classified as normal, incidental, or pathologic. The referr

"Härdelin the Hymnist" Alf Härdelin (1927–2014) was a Swedish theologian and medievalist. In addition to a large academic output, he wrote eleven original hymns and translated 213 from Latin or German into Swedish. This article begins by showing how integrated this activity was with Härdelin’s theological work: both as an academic and as a hymnist he followed the Dominican adage, contemplata alii

Sphingomyelin (SM) is a sphingolipid present in all eukaryotic cell membranes. Hydrolysis of SM by sphingomyelinase (SMase) generates ceramide, which has effects on cell-cycle regulation and apoptosis. Alkaline sphingomyelinase (Alk-SMase) is the main SM-hydrolysing enzyme in the human intestine, and earlier studies have shown that it has anti-proliferative properties on colon cancer cells, and th

A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair. The measurement is based on data collected using the ATLAS detector at the LHC in proton-proton collisions at a centre-of-mass energy of 7 TeV with an integrated luminosity of 4.6fb(-1). Distri

Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0.2< E-gamma
