The ability of particles to activate and form cloud droplets influences the functioning of the Earth's hydrological cycle. This work links the particle water uptake at subsaturation to the critical supersaturation ratio needed for particles to become cloud condensation nuclei (CCN). Five models using the particle hygroscopic growth at subsaturation for predicting the critical supersaturation neede

In order to investigate molecular events involved in the regulation of lymphoid lineage commitment, we crossed lambda5 reporter transgenic mice to Rag1-GFP knock in mice. This allowed us to sub-fractionate common lymphoid progenitors (CLPs) and pre-pro-B (Fraction A) cells into lambda5(-)Rag1(low), lambda5(-)Rag1(high) and lambda5(+)Rag1(high) cells. Clonal in vitro differentiation analysis demons

Background: Gene-virus targeted therapy is a promising new method of treating pancreatic cancer. To increase the efficacy and decrease the side-effect, we constructed a conditionally replicative adenovirus (CRAd) expressing human endostatin, with a human Telomoerase Reverse Transcriptase (hTERT) promoter for the regulation of the early stage of adenovirus expression of gene E1a and a Hypoxia Respo

Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. There are no simple and reliable techniques for prediction of postoperative pain. This study was designed to evaluate if pain induced by venous cannulation or propofol injection can be used to predict postoperative pain.

Aim Our aim was to define the dynamics in collagen concentrations in the large bowel wall following decompression of experimental obstruction. Method Colonic obstruction was created in 28 male rats by the placement of a silicone ring around the distal colon. The ring was removed after 4 days to mimic endoscopical decompression by stent deployment. Colon circumference and collagen concentration wer

Twin studies have shown that criminal behavior (CB) is influenced by both genetic and shared environmental factors. Could these results be replicated using full-siblings and half-siblings?

The Swedish national register of severe alpha1-antitrypsin (AAT) deficiency was established in 1991. The main aims are to prospectively study the natural history of severe AAT deficiency, and to improve the knowledge of AAT deficiency. The inclusion criteria in the register are age ≥18 years, and the PiZ phenotype diagnosed by isoelectric focusing. The register is kept updated by means of repeated

PUFA from oil extracted from Nile perch viscera were enriched by selective enzymatic esterification of the free fatty acids (FFA) or by hydrolysis of ethyl esters of the fatty acids from the oil (FA-EE). Quantitative analysis was performed using RP-HPLC coupled to an evaporative light scattering detector (RP-HPLC-ELSD). The lipase from Thermomyces lanuginosus discriminated against docosahexaenoic

Vitronectin (Vn) is a multifunctional glycoprotein profusely present in serum and bound to epithelial cell surfaces. It plays an important role in cell migration, tissue repair and regulation of membrane attack complex (MAC) formation. In the last decade the role of Vn has been extensively investigated in eukaryotic signalling and cell migration leading to the possibility of developing novel antic

Ionizable pharmaceuticals are a class of emerging contaminants that pose a challenge to analytical chemistry due to their low environmental concentrations. To measure such low concentrations in organism tissue, e.g. fish muscle, specific extraction techniques minimizing co-extraction and interference alongside providing high enrichment of the compounds are needed. In this study we present a techni

This paper describes the vibrationnal feedback that was chosen for the guiding interaction part of the Lund Time Machine application. This tourist guide provides information on points of interests along a trail, and guides the user along it. The interface uses audio and tactile modalities to be accessible in situations where the visual channel is not available. To navigate to the next goal, the us

The lichens Parmelia olivacea and Parmeliopsis ambigua are common epiphytes in subarctic forests in Europe. They differ in abundance and vertical distribution particularly on birch trees, and these differences relate to the level and duration of the winter snow cover. Parmeliopsis ambigua is covered much of the cold season on the lower trunk whereas P. olivacea occurs well above the snow surface.

Vacuum-assisted wound closure (VAC®) therapy is considered to be superior to conventional dressings in the treatment of peri-vascular groin infections after vascular surgery at our department. Therefore, we wanted to perform an early interim analysis of clinical outcome in these seriously ill patients at risk for amputation and death. Patients were randomised to either VAC® (n = 5) or Sorbalgon® (

The coherence spectrum is of notable interest as a bivariate spectral measure in a variety of application, and the topic has lately attracted notable interest with the recent formulation of several high-resolution data adaptive estimators. In this work, we present computationally efficient time recursive implementations of the recent iterative adaptive approach (IAA) estimator, examining both the

In this study, a previously evaluated guided Internet-based cognitive behavior therapy for social anxiety disorder (SAD) was adapted for mobile phone administration (mCBT). The treatment was compared with a guided self-help treatment based on interpersonal psychotherapy (mIPT). The treatment platform could be accessed through smartphones, tablet computers, and standard computers. A total of 52 par

Although climate is known to play an important role in structuring biological communities, high-resolution analyses of recent climatic impacts on multiple components of diversity are still sparse. Additionally, there is a lack of knowledge about which species drive community response to environmental change. We used a long-term breeding bird data set that encompasses a large latitudinal and altitu

Background: Feedback is one of the most significant factors for students’ development of writing skills. For feedback to be successful, however, students and teachers need a common language – a meta-language – for discussing texts. Not least because in science education such a meta-language might contribute to improve writing training and feedback-giving. Purpose: The aim of this study was to exp

A new class of stochastic field models is constructed using nested stochastic partial differential equations (SPDEs). The model class is computationally efficient, applicable to data on general smooth manifolds, and includes both the Gaussian Matérn fields and a wide family of fields with oscillating covariance functions. Nonstationary covariance models are obtained by spatially varying the parame
