Objective: To investigate changes in levels of serum cartilage oligomeric matrix protein (COMP) and urine c-telopeptide of type-2 collagen (CTX-II) as markers for cartilage turnover in patients with osteoarthritis (OA) of the knee, in response to muscle strength training in combination with treatment with glucosamine, ibuprofen or placebo. Design: A 12-week double blind, placebo controlled, random
Light is an important environmental factor controlling biogenic volatile organic compound (BVOC) emissions, but in natural conditions its impact is hard to separate from other influential factors such as temperature. We studied the light response of foliar BVOC emissions, photosynthesis and stomatal conductance on three common European tree species, namely English oak (Quercus robur), European bee
This study investigated the tolerance and safety of pasteurized donor human milk (PDHM) given either alone or together with commercially-used supplements in a porcine model of premature infants. A porcine model, mimicking human neonates at 30-32 weeks of gestational age, was used. The 7-day experiment was performed on 20 piglets. After birth, the piglets were infused with porcine immunoglobulins v
The recent warming trend, and associated shifts in growing season length, challenge the principle of uniformitarianism, i.e., that current relations are persistent over time, and complicates the uncritical inferences of past climate from tree-ring data. Here we conduct a comparison between tree-ring width chronologies of Pinus sylvestris L. (Scots pine), Picea abies (L.) Karst. (Norway spruce) and
The COVID-19 pandemic has impacted production and consumption patterns across the world and forced many organisations to respond. However, there is a lack of understanding as to how sharing platforms have been affected by the pandemic, how they responded to the crisis, and what kinds of long-term implications the pandemic may have on the sharing economy. This study combined systematic literature r
The presence of genes encoding organellar proteins in different cellular compartments necessitates a tight coordination of expression by the different genomes of the eukaryotic cell. This coordination of gene expression is achieved by organelle-to-nucleus communication. Stress-induced perturbations of the tetrapyrrole pathway trigger large changes in nuclear gene expression. In order to investigat
Objective: To explore middle cerebral artery (MCA) and anterior cerebral artery (ACA) blood flow responses to superimposed acute hypoxemia in growth -restricted fetuses with and without established brain-sparing flow during basal conditions. Material and methods: 47 term fetuses suspected of growth restriction were exposed to an oxytocin challenge test with simultaneous cardiotocography and Dopple
Objective— Stretch-induced growth of the vascular wall plays a role in hypertension and neointima formation. Its signal pathways involve integrins, cytoskeleton, membrane receptors, and ion channels, some of which are organized in cholesterol-rich, membrane domains such as lipid rafts or caveolae. This study tested the role of rafts/caveolae in stretch-induced vascular growth by manipulation of me
The fraudulent treatment of cattle with growth promoting agents (GPAs) is a matter of great concern for the European Union (EU) authorities and consumers. It has been estimated that 10% of animals are being illegally treated in the EU. In contrast, only a much lower percentage of animals (< 0.5%) are actually found as being noncompliant by conventional analytical methods. Thus, it has been propose
In his commentary on our article on phenomenological subtypes of highly suggestible individuals (Terhune & Cardeña, in press), Kumar (in press) argues that methodological differences between our studies and previous research on highly suggestible subtypes temper our ability to link the two and that it is unclear whether the existence of phenomenological subtypes has implications for hypnothera
Aim: The study was undertaken to explore whether shortening of striated muscle during activity is associated with release of bound Ca2+ into the myofibrillar space as has previously been proposed in order to explain the depressant effect of active shortening. Methods: The experiments were carried out on single muscle fibres isolated from the anterior tibialis muscle of Rana temporaria. The fibres
Klimatförändringar har amplifierats sedan den industriella revolutionen och modeller pekar på att förändringen kommer forsätta att öka åtminstone till slutet av detta århundrande. Globala temperaturer och nederbörd förväntas öka avsevärt under detta århundrade. Dessa ökningar förväntas bli särskilt markanta i de arktiska områdena. Torvmyrar belägna på höga latituder vid 0ºC isothermen, såsom StorfThe rate of change of our climate has been amplified since the industrial revolution and is expected to change even further by the end of this century. Global temperature and precipitation are expected to increase considerably over the next century. These increases are expected to be magnified in the Arctic regions. In a high latitude peatland like Storflaket, near Abisko (Northern Sweden), at the
Neuropeptide Y (NPY) is a powerful vasoconstrictor in vivo but is usually much less active on isolated blood vessels. The contractile effect of NPY was examined in the isolated rat femoral artery exposed to various degrees of vasoconstriction. The effects of NPY on the relaxation induced by vasodilator agents was also studied. NPY (< or = 1 microM) had no contractile effect. In vessels pretreated
