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

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

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

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

Våren 2000 enades Europeiska Rådet om att senast år 2010 ha förvandlat Europa till världens mest konkurrenskraftiga kunskapsbaserade ekonomi. Riktlinjerna samlades i den s.k. Lissabonstrategin. Genom att kritiskt granska dokument som producerats inom ramen för Kommissionens agenda i2010: "Ett informationssamhälle för tillväxt och konkurrens" vill jag synliggöra hur EU beskriver informat

BACKGROUND: The aim of the study was to determine the role of Vascular Endothelial Growth Factor (VEGF) on the microvasculature and on angiogenetic gene expression after partial hepatectomy (PH) in the rat model.METHODS: To determine the effect of exogenous and endogenous VEGF after PH, rats were subjected to 70% PH and treated either with VEGF, anti-VEGF or NaCl. Postoperatively (3-168 h), vessel

The ability to predict the absorption of exenatide (Ex), a GLP-1 analogue, after oral dosing to rats in self-nanoemulsifying drug delivery systems (SNEDDS), using in vitro methods, was assessed. Ex was complexed with soybean phosphatidylcholine (SPC) prior to loading into SNEDDS. A design of experiments (DoE) approach was employed to develop SNEDDS incorporating medium-chain triglycerides (MCT), m

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

Rural depopulation is a concern in many countries, and various policy initiatives have been taken to combat such trends. This article examines whether hidden potential for rural population growth can be found in Sweden. If such potential exists, it implies that the development prospects for many rural areas are not as unpromising as they may seem today. If not, rapid rural depopulation can be expe

tRNA is the adaptor in the translation process. The ribosome has three sites for tRNA, the: A-, P-, and E-sites. The tRNAs bridge between the ribosomal subunits with the decoding site and the mRNA on the small or 30S subunit and the peptidyl transfer site on the large or 50S subunit. The possibility that, translation release factors could mimic tRNA has been discussed for a long time, since their
