Fibrocytes are associated with vascular and parenchymal remodelling in patients with obliterative bronchiolitis.

BACKGROUND: The aim of the present study was to explore the occurrence of fibrocytes in tissue and to investigate whether the appearance of fibrocytes may be linked to structural changes of the parenchyme and vasculature in the lungs of patients with obliterative bronchiolitis (OB) following lung or bone marrow transplantation. METHODS: Identification of parenchyme, vasculature, and fibrocytes was

Clinical isolates of Enterococcus faecalis aggregate human platelets.

Many endocarditis pathogens activate human platelets and this has been proposed to contribute to virulence. Here we report for the first time that many clinical isolates of Enterococcus faecalis, a common pathogen in infective endocarditis, aggregate human platelets. 84 isolates from human blood and urine were screened for their ability to aggregate platelets from four different donors. Platelet a

HAMLET (human alpha-lactalbumin made lethal to tumor cells) triggers autophagic tumor cell death.

HAMLET, a complex of partially unfolded alpha-lactalbumin and oleic acid, kills a wide range of tumor cells. Here we propose that HAMLET causes macroautophagy in tumor cells and that this contributes to their death. Cell death was accompanied by mitochondrial damage and a reduction in the level of active mTOR and HAMLET triggered extensive cytoplasmic vacuolization and the formation of double-memb

Critical levels of SO2 - uncertainty and relationships to Regional Forest Decline

Three methods estimating adverse effects of SO2 on Norway spruce forests were applied and evaluated on a regional level in northern Czech Republic. The methods, assuming adverse effects to occur when predetermined thresholds are exceeded, include the critical level of SO2 concentration (1), the ratio of the SO2 concentration to the vegetation period (SO2/VP) (2) and a model predicting needle loss

Polymorphic variation in the androgen receptor gene : association with risk of testicular germ cell cancer and metastatic disease

Increasing incidence of testicular germ cell cancer (TGCC) is most probably related to environment and lifestyle. However, an underlying genetic predisposition may play a role and since sex steroids are assumed to be important for the rise and progression of TGCC, a study of androgen receptor (AR) gene polymorphisms in relation to the risk, histological type and progression of TGCC was undertaken.

Erythropoietin Receptor Expression and Correlation to Tamoxifen Response and Prognosis in Breast Cancer.

PURPOSE: The main function of erythropoietin (EPO) is to stimulate erythropoiesis. EPO receptors (EPOR) are expressed in other cell types, including tumor cells, suggesting that the EPO/EPOR pathway governs additional cellular processes besides erythropoiesis. Recombinant EPO (rhEPO) is frequently given to anemic cancer patients, although data on clinical outcome are conflicting. In an attempt to

Verification of dynamic radiotherapy: the potential for 3D dosimetry under respiratory-like motion using polymer gel.

Following the implementation of advanced treatment procedures in radiotherapy, there is a need for dynamic dose verification in 3D. Gel dosimetry could potentially be used for such measurements. However, recently published data show that certain types of gels have a dose rate and fractionation dependence. The aim of this study was to investigate the feasibility of using a polymer gel dosimeter for

Better to Light a Candle: Arthur Barsky and Global Plastic Surgery.

Plastic and reconstructive surgery has had a long history with international humanitarian efforts. As the field of global surgery continues to gain momentum in academic centers throughout the world, the role of the surgical subspecialist in the public health infrastructure of low-resource communities has also begun to gain a new sense of wonder and importance. Arthur Barsky, Jr was arguably one of

Three per cent dextran-60 as a plasma substitute in blood component therapy. I. An alternative in surgical blood loss replacement.

Microaggregate-poor erythrocyte concentrate with 3% dextran-60 as a plasma substitute was compared with microaggregate-poor whole blood for replacement of intra-operative and immediately postoperative blood loss. Sixty patients undergoing total hip arthroplasty randomly received either of these two forms of therapy. In accordance with the clinical routine of our orthopedic department, an infusion

Neuroinflammation in the generation of post-transplantation dyskinesia in Parkinson's disease.

The observation that neural grafts can induce dyskinesias has severely hindered the development of a transplantation therapy for Parkinson's disease (PD). We addressed the hypothesis that inflammatory responses within and around an intrastriatal graft containing dopamine neurons can trigger dyskinetic behaviors. We subjected rats to unilateral nigrostriatal lesions with 6-hydroxydopamine (6-OHDA)

Oral health problems and support as experienced by people with severe mental illness living in community-based subsidised housing - a qualitative study.

Abstract The purpose of this study was to explore how persons with severe mental illness (SMI) experience oral health problems (especially dry mouth), and weigh the support they received in this regard from professionals and staff at community-based congregate housing through a controlled intervention programme. Oral health problems and dry mouth are found in association with apathy and indifferen

Myocardium at risk by magnetic resonance imaging: head-to-head comparison of T2-weighted imaging and contrast-enhanced steady-state free precession.

AIMS: To determine the myocardial salvage index, the extent of infarction needs to be related to the myocardium at risk (MaR). Thus, the ability to assess both infarct size and MaR is of central clinical and scientific importance. The aim of the present study was to explore the relationship between T2-weighted cardiac magnetic resonance (CMR) and contrast-enhanced steady-state free precession (CE

From lymph to fat: liposuction as a treatment for complete reduction of lymphedema.

There is some controversy regarding liposuction for late-stage lymphedemas. Although it is clear that conservative therapies such as complex decongestive therapy and controlled compression therapy should be tried in the first instance, options for the treatment of late-stage lymphedema that is not responding to treatment is not so clear. Liposuction has been used for many years to treat lipodystro

Combination of FVIII and by-passing agent potentiates in vitro thrombin production in haemophilia A inhibitor plasma.

The by-passing agents, recombinant activated factor VII (rFVIIa) and activated prothrombin complex concentrate (APCC), are important tools in the treatment of patients with haemophilia A and high-responding inhibitory antibodies. It has been observed clinically that in some patients undergoing immune tolerance induction the bleeding frequency decreases, hypothetically caused by a transient haemost

Investigation of disease-associated factors in haemophilia A patients without detectable mutations.

Summary. To investigate disease causing mechanism in haemophilia A patients without detectable mutation. Screening for F8 mutations in 307 haemophilia A patients using: re-sequencing and inversion PCR, reverse transcription (RT-PCR) of mRNA, MLPA analysis, haplotyping using SNP and microsatellite markers. No F8 mutations were detected in 9 of the 307 patients (2.9%) using re-sequencing and inversi

Recreational values of the natural environment in relation to neighbourhood satisfaction, physical activity, obesity and wellbeing.

OBJECTIVES: The aim of this population-based study was to investigate associations between recreational values of the close natural environment and neighbourhood satisfaction, physical activity, obesity and wellbeing. METHODS: Data from a large public health survey distributed as a mailed questionnaire in suburban and rural areas of southern Sweden were used (N = 24,819; 59% participation rate). G
