Multi-component stable isotope records from Late Weichselian and early Holocene lake sediments at Imiolki, Poland: palaeoclimatic and methodological implications

Late Weichselian and early Holocene climatic and environmental changes are inferred from stable carbon and oxygen isotope records obtained on bulk and biogenic carbonates from the sediment sequence of Lake Lednica, western Poland. Along with sediment and pollen stratigraphic data, a wide range of carbonate components occurring in the sediments was analysed for delta C-13 and delta O-18, including

Development in children born very preterm after intrauterine growth restriction with abnormal fetal blood flow

Delivery of fetuses with intrauterine growth restriction (IUGR) with abnormal umbilical artery blood flow in the second trimester represents a clinical dilemma. So far, no evidence based management protocols are available adressing when to deliver these fetuses. The high risk of hypoxia and fetal death has to be balanced against that of extreme preterm birth with associated morbidity. The clinical

By activating matrix metalloproteinase-7, shear stress promotes chondrosarcoma cell motility, invasion and lung colonization.

Interstitial fluid flow and associated shear stress are relevant mechanical signals in cartilage and bone (patho)physiology. However, their effects on chondrosarcoma cell motility, invasion and metastasis have yet to be delineated. Using human SW1353, HS.819.T and CH2879 chondrosarcoma cell lines as model systems, we found that fluid shear stress induces the accumulation of cyclic AMP (cAMP) and i

Multicenter assessment of venous reflux by duplex ultrasound

Objective: This prospective multicenter investigation was conducted to define the repeatability of duplex-based identification of venous reflux and the relative effect of key parameters on the reproducibility of the test. Methods: Repeatability was studied by having the same technologist perform duplicate tests, at the same time of the day, using the same reflux-provoking maneuver and with the pat

Structure of premixed ammonia plus air flames at atmospheric pressure: Laser diagnostics and kinetic modeling

The structure of premixed ammonia air flames, burning at atmospheric pressure under strain-stabilized conditions on a porous-plug burner, has been investigated using laser-diagnostic methods. Profiles of OH, NH, and NO were acquired by laser-induced fluorescence (LIF) and quantitative concentrations of OH and NO were retrieved using a concept for calibration versus absorption utilizing the LIF-sig

Novel boron-10-based detectors for neutron scattering science

Nowadays neutron scattering science is increasing its instrumental power. Most of the neutron sources in the world are pushing the development of their technologies to be more performing. The neutron scattering development is also pushed by the European Spallation Source (ESS) in Sweden, a neutron facility which has just started construction. Concerning small-area detectors (similar to 1 m(2)), th

Shape evolution and magnetic rotation in Nd-141

The high-spin states in Nd-141 were investigated using the Zr-96(Ca-48, 3n) reaction and the EU-ROBALL array. The level scheme has been extended up to an excitation energy of around 16MeV and spin 81/2. Two new bands of dipole transitions and three bands presumably of quadrupole transitions were identified and their connections to low-lying states were established. Cranked Nilsson-Strutinsky and t

Antidiabetic Actions of an Estrogen Receptor beta Selective Agonist

The estrogen receptor beta (ER beta) is emerging as an important player in the physiology of the endocrine pancreas. We evaluated the role and antidiabetic actions of the ER beta selective agonist WAY200070 as an insulinotropic molecule. We demonstrate that WAY200070 enhances glucose-stimulated insulin secretion both in mouse and human islets. In vivo experiments showed that a single administratio

alpha-decay calculations of heavy nuclei using an effective Skyrme interaction

Background: For nuclei heavier than Pb-208 alpha decay is a dominating decay mode, and in the search of new superheavy elements one often observes chains of alpha decays. Purpose: Explore and test microscopic descriptions of alpha decay based on theories with effective nuclear interactions. Methods: The nuclear ground states are calculated with the Hartree-Fock-Bogoliubov (HFB) method using the Sk

Non-Main Clause Linking and Verb Form Switch in Syrian Arabic. Is there a circumstantial clause?

Recent research has brought into focus the function of switching between verb forms and types of clauses, here labelled ‘gram switching’, as a device for marking non-main clause linking in various types of Arabic and in Biblical Hebrew (Persson forthcoming a; Isaksson, Kammensjö, and Persson 2009; Isaksson 2011, 2013). The study presented here shows that a switch, either in verb form/morphology or

ENHANCE YOUR WORKPLACE! A dialogue tool for workplace health promotion with a salutogenic approach

Popular Abstract in Swedish Arbetsplatsens positiva sidor kan förbättras genom ett nytt dialogverktyg! Nu går det att mäta medarbetares positiva upplevelser av arbete. Vanligtvis kopplas människors upplevelser av arbete samman med stress och ohälsa. Men det går att tänka tvärtom, att istället fokusera på allt det positiva som arbete kan ge. När människor mår bra av sitt arbete, blir de också mer The aim of this thesis was to develop and make a quality assessment of a tool, which includes a questionnaire and a dialogue process that could be useful for workplace health promotion from a salutogenic point of view. The studies have been performed within two health care organizations between 2005 and 2009, together with hospital staff. Two questionnaire studies were conducted (n=446 n=505, resp

Impaired Tethering and Fusion of GLUT4 Vesicles in Insulin-Resistant Human Adipose Cells

Systemic glucose homeostasis is profoundly influenced by adipose cell function. Here we investigated GLUT4 dynamics in living adipose cells from human subjects with varying BMI and insulin sensitivity index (S-i) values. Cells were transfected with hemagglutinin (HA)-GLUT4-green fluorescent protein (GFP)/mCherry (red fluorescence), and were imaged live using total internal reflection fluorescence
