Popular Abstract in Swedish Alla växter utsätts för någon form av stress i sin dagliga miljö. Till exempel råder det väldigt sällan optimala tillväxtförhållanden på en åker, där ogräsen konkurrerar, insekterna knaprar, svamparna frodas och olika näringsbrister kan råda, för att inte tala om de torra somrarna. Det är alltså troligt att en växt utsätts för ett flertal stressfaktorer samtidigt, vilkePlants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. In this work the intera

Background: To assess balance in single-limb stance, center of pressure movements can be registered by stabilometry with force platforms. This can be used for evaluation of injuries to the lower extremities. It is important to ensure that the assessment tools we use in the clinical setting and in research have minimal measurement error. Previous studies have shown that the ability to maintain stan

Abstract in FinnishSex-determination is commonly categorized as either "genetic" or "environmental"-a classification that obscures the origin of this dichotomy and the evolution of sex-determining factors. The current focus on static outcomes of sex-determination provides little insight into the dynamic developmental processes by which some mechanisms acquire the role of sex determinants. Systems

T cells are crucial players in cell-mediated immunity. The specificity of their receptor, the T cell receptor (TCR), is central for the immune system to distinguish foreign from host antigens. Superantigens are bacterial toxins capable of inducing a toxic immune response by cross-linking the TCR and the major histocompatibility complex (MHC) class II and circumventing the antigen specificity. Here

Objective. To estimate the incidence of dystocia among nulliparous women without apparent co-morbidity and to examine maternal and fetal short-term outcomes after dystocia. Design. A multi-center cohort study with prospectively collected data. Setting. Nine obstetric departments with annual birth rates between 850 and 5,400. Population. Low-risk nulliparous women in term spontaneous labor with a s

Popular Abstract in Swedish Diabetes mellitus är en samling sjukdomar som karaktäriseras av förhöjt blodsocker. Traditionellt har man delat upp sjukdomen i två former; typ 1 och typ 2 diabetes. Vid typ 1 diabetes förstörs de insulinproducerande β-cellerna i bukspottskörteln av kroppens immunförsvar och sjukdomen debuterar ofta tidigt i livet. Typ 2 diabetes, tidigare ofta benämnd ”åldersdiabetes” Inadequate insulin secretion is a central component in the development of Diabetes Mellitus, resulting from reduced pancreatic β-cell mass, as well as diminished β-cell function. Islet produced 5-hydroxy tryptamine (5-HT) is suggested to regulate insulin secretion and β-cell mass in rodents during pregnancy and in metabolically challenged states. However, the role of 5-HT in control of insulin rel

The study is based on monitoring data on the seasonal variation during four (1996-1999) vegetation periods, as well as long-term summer data on submerged vegetation, nutrients, light, phyto-plankton and zooplankton in Lake Krankesjon, a shallow, calcium-rich, moderately eutrophic take in southern Sweden. The lake has been in the clear water state with abundant submerged vegetation since the end of

Background. The aim of this study was to investigate differences in use of antenatal care in a multi-ethnic population in Malmo, Sweden, over a 4-year period. Age, parity, cohabiting status, use of an interpreter, and tobacco-use were examined to assess the potential effects of confounding factors. Methods. A 4-year (2000-2003) retrospective community-based register study was performed. Low-risk s

The inner relative humidity (RH) and degree of saturation (S) of high-performance concrete cured for 2 years in water or 3% NaCl solution were measured at three different levels from the concrete surface (outer layer 0 to 16 mm, middle layer 16 to 32 mm, and inner layer 32 to 50 mm). The effects of many factors, such as water-to-cement (w/c) ratio, content of silica fume, and air content, were inv

Apparent standard Gibbs energy, enthalpy, entropy, and heat capacity data of the interactions of alpha-cyclodextrin (alphaCD) to some n-carboxylates H(CH2)(n)COO- (n = 4 - 6), are determined by isothermal titration microcalorimetry at different temperatures in phosphate buffer, pH 9.0, assuming a 1 : 1 model in dilute solution. Modelling of contributions of the thermodynamic properties of the solu

Popular AbstractDetta är en histora över teorier om ojämnt utbyte och deras upphovsmän. Den börjar med merkantilismen och Richard Cantillons jordvärdeteori, ger en kort beskrivning av tidig klassisk ekonomi och Gerald Fitzhugh. Bland det tidiga 1900-talets marxistiska ekonomer spelade ojämnt utbyte en roll i Otto Bauers tolkning av nationalistiska motsättningar, och i Henryk Grossmanns verk som enThis is a history of theories and theorists of unequal exchange. Starting with mercantilists and Richard Cantillon's theory based on land values, it briefly covers the early Classical economists and Gerald Fitzhugh. Among early 20th century Marxist economists, unequal exchange appeared in Otto Bauer's explanation of nationalist antagonism, and in Henryk Grossmann as countering the breakdown of cap

Positional cloning of susceptibility genes in complex diseases like rheumatoid arthritis in humans is hampered by aspects like genetic heterogeneity and environmental variations, while genetic studies in animal models contain several advantages. With animal models, the environment can be controlled, the genetic complexity of the disease is minimized and the disease onset can be predicted, which si

The effect of warmer climate on the depletion of snow-covered area has been evaluated for the Satluj River basin located in the western Himalayan region in India. Snowmelt runoff contributes substantially to the annual streamflow of this river. In order to study the impact of three warming scenarios (T+1, T+2 and T+3degreesC), more than 160 new snow depletion curves were prepared for different ele
