It is likely that everyone will, at some time, suffer from a problem related to the musculoskeletal system, ranging from a very common problem such as osteoarthritis or back pain to severely disabling limb trauma or rheumatoid arthritis. Many musculoskeletal problems are chronic conditions. The most common symptoms are pain and disability, with an impact not only on individuals’ quality of life bu
Platelet-derived growth factors (PDGFs) are important in many types of mesenchymal cell. Here we identify a new PDGF, PDGF-C, which binds to and activates the PDGF alpha-receptor. PDGF-C is activated by proteolysis and induces proliferation of fibroblasts when overexpressed in transgenic mice. In situ hybridization analysis in the murine embryonic kidney shows preferential expression of PDGF-C mes
Clinical islet transplantation is currently being explored as a treatment for persons with type 1 diabetes and hypoglycaemia unawareness. Although 'proof-of-principle' has been established in recent clinical studies, the procedure suffers from low efficacy. At the time of transplantation, the isolated islets are allowed to embolise the liver after injection in the portal vein, a procedure that is
1.Among small animals dispersal parameters are mainly obtained by traditional methods using population studies of marked individuals. Dispersal studies may underestimate the rate and distance of dispersal, and be biased because of aggregated habitat patches and a small study area. The probability of observing long distance dispersal events decreases with distance travelled by the organisms. In thi
Policies to reduce household energy use usually target the individual customer. This is probably one explanation for the limited effect of many information policies, because two concepts with different meanings are confused: individual and household. In most contexts, an individual stands for what s/he does, but in the policy context, an individual is taken to represent the entire household. This
INTRODUCTION: There is an increasing number of elderly in society and some of them may have an abdominal aortic aneurysm (AAA). The prevalence of AAA in octo-And nonagenarians indicates that this number could be substantial. The question is: is there an age limit for repair? This complex question incorporates ethical, political, economic and medical aspects. To answer part of this question a revie
We address a new agricultural policy concern following the decoupling of CAP direct payments in 2005: passive farming, whereby landowners maintain their agricultural area to collect payments without producing commodities. It is claimed that passive farming is hindering agricultural development by 'blocking' access to farmland for expanding farmers. We evaluate the links between the EU's Single Pay
Recent developments in rotational CARS thermometry and critical issues when comparing vibrational and rotational CARS thermometry are described. In particular, the development of dual broadband rotational CARS and the noise characteristics of this approach are emphasized. The difficulty with unambiguous temperature determination in vibrational CARS with unknown parameters, in particular the nonres
Many experiments have shown that loss of biodiversity reduces the capacity of ecosystems to provide the multiple services on which humans depend. However, experiments necessarily simplify the complexity of natural ecosystems and will normally control for other important drivers of ecosystem functioning, such as the environment or land use. In addition, existing studies typically focus on the diver
This paper concerns the proper definition of embeddings in purely category-theoretical terms. It is argued that plain category theory cannot capture what, in the general case, constitutes an embedding of one structure in another. We discuss three available solutions to this problem: variants of monics, concrete categories, and allegories. The first and last of these are found to be unable to solve
The potential collapse of Assad’s regime would disturb not only the regional but also trans-regional balance of power at the expense of Iran, leaving it virtually alone amidst foes such as Saudi Arabia and Israel, and rivalrous friends such as Turkey and (potentially) Egypt. The IRI officials have made no secret of their strong desire that Syria under Assad should be protected from what is usually
This paper presents findings from a longitudinal, experimental project investigating the effect of translation on the morphosyntactic accuracy of advanced Swedish (L1) learners of English (L2). The subjects were first-year students of English at a Swedish university. The curriculum was communicative and translation (Focus-on-Forms) was used judiciously. The research is couched in cognitive psycho
In mitosis, transcription factors (TFs) and RNA polymerase disperse across the cytoplasm leading to transcriptional silencing, but some TFs are retained on condensed chromatin and mark genomic sites, a mechanism termed mitotic bookmarking. In pluripotent and differentiated cells this mechanism is important for pluripotency maintenance, cell reprogramming and lineage inheritance. However, the role
Humanity injects an almost incomprehensible 42 billion tonnes of carbon dioxide (CO₂) into the atmosphere every year. The majority of this comes from burning fossil fuels, but a substantial portion, about 16%, arises from how we use the land. Most of these land-use emissions are caused by deforestation, particularly in the tropics.In order to slow climate change, the global community needs to redu
