Aim: To investigate the application of skin-to-skin care (SSC) in the Nordic countries, the existence of guidelines for SSC and the attitudes of neonatal staff towards SSC. Methods: One questionnaire was distributed at unit level and one at staff level in all Nordic neonatal intensive care units (n = 109). Results: The unit questionnaire was answered by 95 (87%) units and the staff questionnaire b
Background: Intraventricular hemorrhage (IVH) with post-hemorrhagic ventricular dilatation (PHVD) is a major cause of neurodevelopmental impairment and mortality in preterm infants. The mechanisms leading to PHVD and brain damage remain largely unknown. The choroid plexus and the ependyma, which constitute an essential part of the blood-brain barrier (BBB), are the first structures to encounter th
The brick kiln at Saltsjö Boo is one of very few such structures known from medieval Sweden. Approx ¾ of the kiln has been excavated in successive short excavations from 2006 to 2011. Carbon 14 and TL (Thermoluminiscence) analyses indicate that the kiln has been in operation from c. 1250 to c.1450. This paper presents the results of the excavations and discusses the production of bricks and indust
Salinization of soil is recognised as one of the most pressing environmental challenges to resolve for the next century. We here conduct a synoptic review of the available research on how salt affects decomposer microbial communities and carbon (C) cycling in soil. After summarizing known physiological responses of microorganisms to salinity, we provide a brief overview and qualification of a sele
Background: Tumour necrosis factor-alpha (TNF-alpha) is a pleiotropic pro-inflammatory cytokine, which is rapidly upregulated in the brain after injury. TNF-alpha acts by binding to its receptors, TNF-R1 (p55) and TNF-R2 (p75), on the cell surface. The aim of this study was first to investigate if there is altered expression of TNF-alpha and TNF-alpha receptors in cerebral artery walls following g
The administration of hydroxocobalamin (OHCob), alone or with sodium thiosulfate, is a standard therapy for cyanide poisoning. OHCob is a red chromophore, and its interference with co-oximetric and colorimetric laboratory measurements has been evaluated in a few conflicting reports. The interference of OHCob was investigated in samples spiked with 10 different concentrations of OHCob (0-1500 mg/L)
Readouts that define the physiological distributions of drugs in tissues are an unmet challenge and at best imprecise, but are needed in order to understand both the pharmacokinetic and pharmacodynamic properties associated with efficacy. Here we demonstrate that it is feasible to follow the in vivo transport of unlabeled drugs within specific organ and tissue compartments on a platform that appli
Purpose: Cells in the ependymal region in the adult central nervous system (CNS) have been found to possess neural progenitor cell (NPC) like features including capacity for generating new neurons and glia in response to injury and inflammatory disease. Whether these cells are activated after a peripheral nerve injury has not previously been extensively evaluated. Methods: We investigate the possi
The correlation between surface structure, stoichiometry and atomic occupancy of the polar MgAl2O4(100) surface has been studied with an interplay of noncontact atomic force microscopy, X-ray photoelectron spectroscopy and surface X-ray diffraction under ultrahigh vacuum conditions. The Al/Mg ratio is found to significantly increase as the surface is sputtered and annealed in oxygen at intermediat
We report on he growth of single crystal InAs nanowires on Si/SiOx substrates by chemical vapor deposition (CVD). Both pure zincblende InAs nanowires and twin superlattice InAs nanowires are produced. We demonstrate that the morphology and crystal structure of these nanowires can be controlled by tuning the H-2 carrier gas How rate in a CVD furnace and show that highly selected growth of twin supe
Experiments with birch bark samples have been carried to enable a distinction between extraction and degradation effects during pressurised hot water extraction. Two samples, E80 and El 80, contained birch bark extracts obtained after extraction at 80 and 180 degrees C for up to 45 min, respectively. Two other samples, P80 and P180, were only extracted for 5 min at the two temperatures and were th
Measurements of the centrality and rapidity dependence of inclusive jet production in root(NN)-N-S = 5.02 TeV proton-lead (p + Pb) collisions and the jet cross-section in root s = 2.76 TeV proton-proton collisions are presented. These quantities are measured in datasets corresponding to an integrated luminosity of 27.8 nb(-1) and 4.0 pb(-1), respectively, recorded with the ATLAS detector at the La
Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. A continuous anaerobic/aerobic laboratory system was operated on synthetic wastewater with acetate as sole carbon source. An ef
Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. The studies in this work invol
A new 5-station beamline for protein crystallography is being commissioned at the Swedish synchrotron light source MAX-II at Lund University. Of the 2K/gamma = 14 mrad horizontal wiggler fan, the central 2 mrad are used and split in three parts. The central 1 mrad will be used for a station optimized for MAD experiments and on each side of the central fan, from 0.5 mrad to 1 mrad, there are two fi
Popular Abstract in Swedish Evolution är förändringen av en egenskap över flera generationer i en population. För att en sådan förändring ska kunna ske måste ärftlig variation finnas i populationen. Med detta menas att en gen som påverkar en egenskap, t.ex. en fågels vinglängd, måste finnas i olika former, så kallade alleler, som har olika effekt på egenskapen (t.ex. längre eller kortare vinge). MLong-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population. In this thesis I describe the utilization of a great reed warb
