Do they know what they are doing? Risk perceptions and smoking behaviour among Swedish teenagers

Cross-sectional survey data on Swedish adolescents aged 12 - 18 was used to analyse perceived risks of smoking-related lung cancer, the determinants of these risk perceptions, and how these perceptions related to smoking behaviour. Three major conclusions were drawn: ( 1) that both smokers and non-smokers overestimated the risks of lung cancer, ( 2) that these risk perceptions fell substantially w

Sustained attention analyzed by a new computerized dark adaptometer

A new computerized dark adaptometer was developed achieving a 50% reduction of examination time. Functions were implemented for the recording of sustained attention (ie, the capacity to maintain focus and alertness over time (vigilance)). Eighteen healthy subjects were tested three times each on different days. All tests were analyzed for parameters analogous to measurements derived from continuou

Relationship between pressure-volume curve and markers for collagen turn-over in early acute respiratory distress syndrome

OBJECTIVE: In acute respiratory distress syndrome, the relationships between changes in the elastic behavior of the respiratory system and biological markers of extra-cellular matrix or surfactant turn-over could give some insights into its pathophysiological determinants. DESIGN AND MEASUREMENTS: In 17 patients with acute respiratory distress syndrome, we assessed the relationship between chord c

Stability of rotating states in a weakly interacting Bose-Einstein condensate

We investigate the lowest state of a rotating, weakly interacting Bose-Einstein condensate trapped in a harmonic confining potential that is driven by an infinitesimally asymmetric perturbation. Although in an axially symmetric confining potential the gas has an axially symmetric single-particle density distribution, we show that in the presence of the small asymmetric perturbation its lowest stat

Modelling the role of agriculture for the 20th century global terrestrial carbon balance

In order to better assess the role of agriculture within the global climate-vegetation system, we present a model of the managed planetary land surface, Lund-Potsdam-Jena managed Land (LPJmL), which simulates biophysical and biogeochemical processes as well as productivity and yield of the most important crops worldwide, using a concept of crop functional types (CFTs). Based on the LPJ-Dynamic Glo

Fusion of the MORF and CBP genes in acute myeloid leukemia with the t(10;16)(q22;p13)

The CBP gene at 16p13 fuses to MOZ and MLL as a result of the t(8;16)(p11;p13) in acute (myelo)monocytic leukemias (AML M4/M5) and the t(11;16)(q23;p13) in treatment-related AML, respectively. We show here that a novel t(10;16)(q22;p13) in a childhood AML M5a leads to a MORF-CBP chimera. RT-PCR using MORF forward and CBP reverse primers amplified a MORF-CBP fusion in which nucleotide 3103 of MORF

Distress and coping in cancer patients: feasibility of the Icelandic version of BSI 18 and the WOC-CA questionnaires.

The aim of this study was to test the feasibility of two instruments within an Icelandic context, the Brief Symptom Inventory 18 (BSI 18) and the Ways of Coping Inventory – Cancer Version (WOC-CA) with specific focus on gender and type of treatment and coping techniques among cancer patients during time of treatment. The sample consisted of 40 cancer patients in three oncology outpatient clinics i

Nanowire growth and dopants studied by cross-sectional scanning tunnelling microscopy

Using a crystalline embedding scheme it has recently become possible to study free-standing III - V nanowires with cross-sectional scanning tunnelling microscopy (XSTM). In the present paper we discuss how this novel method can be used for direct atomically resolved imaging of the interior of nanowires. We will focus in particular on two areas where this method provides unique possibilities. First

Unwanted pregnancy as a risk factor for offspring schizophrenia-spectrum and affective disorders in adulthood: a prospective high-risk study.

BACKGROUND: This study investigated whether 'unwanted pregnancy' (i.e. a negative or ambivalent attitude towards the pregnancy/reproduction) is associated with schizophrenia-spectrum and affective disorders in the offspring in adulthood, and if so, whether other pregnancy, perinatal, childhood or genetic-risk factors account for this association.MethodIn a prospective study beginning during pregna

Nu startar projekt Skånes Mossor!

The Lund Botanical Society 2007-03-23 decided to launch a project with the following aims: 1) to map the frequency and distribution of all bryophytes in the province of Skåne, southernmost Sweden, thereby making way for future studies of changes in the flora, 2) to find and document as many sites as possible for nationally and regionally rare or endangered bryophytes and initiate conservation acti

NMR, cloud-point measurements and enzymatic depolymerization: Complementary tools to investigate substituent patterns in modified celluloses

The substituent patterns of some chemically modified celluloses were characterized as a function of their size distribution, using size-exclusion chromatography coupled to both nuclear magnetic resonance spectroscopy (NMR) and cloud-point measurements. Intact and enzymatically hydrolyzed methyl cellulose (MC) was fractionated according to size, and the level of substitution of the fractions was me

Sentinel node imaging

Breast cancer and melanoma metastasize predominantly via the lymphatic route. It has long been known that invasion into one or a few nodes draining the primary tumour, the sentinel nodes (SN), is the most important, early sign of dissemination. If no malignant cells are detected in the SN, dissemination is unlikely to be expected. For the last 10 years SN biopsy has become an important tool in sta
