Exocomet signatures around the A-shell star φ Leonis?

We present an intensive monitoring of high-resolution spectra of the Ca ii K line in the A7IV shell star φ Leo at very short (minutes, hours), short (night to night), and medium (weeks, months) timescales. The spectra show remarkable variable absorptions on timescales of hours, days, and months. The characteristics of these sporadic events are very similar to most that are observed toward the debr

Supported employment adapted for people with affective disorders : A randomized controlled trial

Background While effective vocational methods for gaining employment exist for people with schizophrenia and similar conditions, no evidence exists with regard to people with affective disorders. We aimed to study the effectiveness of a newly developed Individual Enabling and Support (IES) model adapted for the target group and compared to traditional vocational rehabilitation (TVR). Methods An as

Subpopulations of T regulatory cells in blood stem cell harvests influence development of acute graft versus host disease in allogeneic transplant recipients

Background: CD4+ FoxP3+ regulatory T cells (Tregs) are the potent suppressors of activation and proliferation of conventional T cells. Tregs subdivided by their expression of FoxP3 and CD45RA identify clinically important functional subsets. Methods: We analyzed Treg subpopulations in hematopoietic stem cell harvests (SCH) from 22 allogeneic (matched unrelated and sibling) donors with flow cytomet

Structural effects of sprifermin in knee osteoarthritis : a post-hoc analysis on cartilage and non-cartilaginous tissue alterations in a randomized controlled trial

Background: A recent publication on efficacy of Sprifermin for knee osteoarthritis (OA) using quantitatively MRI-defined central medial tibio-femoral compartment cartilage thickness as the structural primary endpoint reported no statistically significant dose response. However, Sprifermin was associated with statistically significant, dose-dependent reductions in loss of total and lateral tibio-fe

Survival of entrepreneurial firms : the role of agglomeration externalities

This paper analyzes the role of various types of agglomeration externalities on the survival rate of entrepreneurial firms. In particular, we trace the population cohort of newly-established and self-employed Swedish firms in the Knowledge-Intensive Business Service sector in 1997 up to 2012 and investigate the role of Marshallian and Jacobian externalities on the survival of these firms. We find

Measurement of antihaemophilic factor A antigen (VII:CAg) with a solid phase immunoradiometric method based on homologous non-haemophilic antibodies.

Antihaemophilic-factor-A-antibodies, which had spontaneously arisen in 2 patients, were used to develop an immunoradiometric method for measurement of antihaemophilic factor A antigen (VIII:CAg). 13 patients with severe haemophilia A had VIII: CAg below the limit of detection (0.01 U/ml). Patients with moderate and mild haemophilia A either had VIII:CAg roughly equal to factor VIII clotting activi

How do carriers of hemophilia and their spouses experience prenatal diagnosis by chorionic villus sampling?

A semistructured personal interview with 29 female carriers of hemophilia and 23 of their spouses was performed at a median of 3 1/2 years after the first chorionic villus sampling (CVS) and gene analysis. Carriers with a hemophilic father or brother, had high sense of coherence (SOC) scores, and thus would be expected to have good ability to handle the stress of prenatal diagnosis (PD). Prenatal

The incidence and distribution of CpG----TpG transitions in the coagulation factor IX gene. A fresh look at CpG mutational hotspots

The mutations of 76 haemophilia B patients representing the whole population registered with the Malmö haemophilia centre (42) and referrals from the UK, were characterised. RFLP haplotype analysis of the defective genes indicated that 51 single base pair substitutions were definitely of independent origin and 27 of these were CpG----TpG or CpA transitions. This represents a 38-fold excess over ot

Adverse events in orthopedic care identified via the Global Trigger Tool in Sweden - implications on preventable prolonged hospitalizations

Background: The national incidence of adverse events (AEs) in Swedish orthopedic care has never been described. A new national database has made it possible to describe incidence, nature, preventability and consequences of AEs in Swedish orthopedic care. Methods: We used national data from a structured two-stage record review with a Swedish modification of the Global Trigger Tool. The sample was 4

Two factor IX mutations in the family of an isolated haemophilia B patient : direct carrier diagnosis by amplification mismatch detection (AMD)

Rapid identification of gene defects allows definite carrier and prenatal diagnosis in virtually every family with haemophilia B. We report a study of the family of an isolated patient. Analysis of all the essential regions of the patient's factor IX gene (promoter, exons, transcript processing signals) revealed two mutations: one C----T transition at residue 17762 and another at residue 30890. Th

Moderate haemophilia B in a female carrier caused by preferential inactivation of the paternal X chromosome

The case of a female with moderate haemophilia B is reported. She is the only affected member of her family, and factor IX RFLP analysis shows her to have inherited no maternal markers for polymorphisms located in the first intron and 8 Kb 3' of the polyadenylation signal (DdeI and HhaI, respectively). This clearly indicates a deletion involving at least the last 7 exons of the factor IX gene. Her

More than half the sporadic cases of Hemophilia A in Sweden are due to a recent mutation

The aim of this study was to ascertain how many of the sporadic cases of severe Haemophilia A in Sweden are due to recent mutation, and establish its origin. DNA analysis was performed in 18 randomly selected families with a sporadic case of severe haemophilia A. Restriction fragment length polymorphism (RFLP) patterns were investigated, two intragenic (Bc1 I, Xba I/Kpn I) and two extragenic (DX 1

Population genetics of the Malmö polymorphism of coagulation factor IX

The distribution of 1.198 Malmö alleles was examined in 822 men from 16 indigenous populations and 188 women from 7 of the ethnic groups. Subjects were from several European countries, the Mediterranean, East Asia, and the USA (Anglo- and African-Americans). The frequencies of the rarer (Malmö B) allele were approximately equal across Europe, the highest frequencies (0.36) being in the French and

Identification of two distinct mesenchymal stromal cell populations in human malignant glioma

Gene profiling has revealed that malignant gliomas can be divided into four distinct molecular subtypes, where tumors with a mesenchymal gene expression are correlated with short survival. The present investigation was undertaken to clarify whether human malignant gliomas contain endogenous mesenchymal stromal cells (MSC), fulfilling consensus criteria defined by The International Society for Cell
