Immunohistochemical detection of tyrosine phosphatase SHP-1 predicts outcome after radical prostatectomy for localized prostate cancer.

The protein tyrosine kinase (PTK) receptors and cytosolic signaling proteins as well as the protein tyrosine phosphatases (PTPs) have important roles in regulation of growth of the benign and malignant prostate gland. Here we studied expression of the protein tyrosine phosphatase SHP-1 in prostate cancer cell lines and in human prostatic tissues. SHP-1 is expressed at a high level in LNCaP prostat

GLP-1-based therapy of type 2 diabetes: GLP-1 mimetics and DPP-IV inhibitors.

Glucagon-like peptide-1 (GLP-1)-based therapy is a novel treatment for type 2 diabetes. It is executed either by GLP-1 mimetics or by dipeptidyl peptidase-IV inhibitors. In type 2 diabetes, the two strategies reduce hemoglobin A(1c) by 0.6% to 1.1% from baseline levels of 7.7% to 8.5%. They are efficient both in monotherapy and in combination with metformin or thiazolidinediones. Both treatments a

Zoom-in array comparative genomic hybridization (aCGH) to detect germline rearrangements in cancer susceptibility genes.

Disease predisposing germline mutations in cancer susceptibility genes may consist of large genomic rearrangements, including deletions or duplications that are challenging, to detect and characterize using standard PCR-based mutation screening methods. Such rearrangements range from single exons up to hundreds of kilobases of sequence in size. Array-based comparative genomic hybridization (aCGH)

Crystallization and Structure Determination of Superantigens and Immune Receptor Complexes.

Structure determination of superantigens and the complexes they form with immune receptors have over the years provided insight in their modes of action. This technique requires growing large and highly ordered crystals of the superantigen or receptor-superantigen complex, followed by exposure to X-ray radiation and data collection. Here, we describe methods for crystallizing superantigens and sup

Angptl4 maintains in vivo repopulation capacity of CD34(+) human cord blood cells.

OBJECTIVES: Methods to expand hematopoietic stem cells (HSCs) ex vivo encompass an attractive approach that would substantially broaden the clinical applicability of HSCs derived from cord blood. Recently, members of the Angiopoietin-like (Angptl) family of growth factors were shown to expand both murine and human HSCs. Specifically, Angptl5 has been implicated in the expansion of human NOD-SCID-

Evidence-based practice in a multiprofessional context

BACKGROUND: Healthcare today is a complex system with increasing needs of specific knowledge of evaluation of research and implementation into clinical practice. A critical issue is that we all apply evidence-based practice (EBP) with standardised methods and continuing and systematic improvements. EBP includes both scientific and critical assessed experience-based knowledge. For the individual,

Differences in QRS axis measurements, classification of inferior myocardial infarction, and noise tolerance for 12-lead electrocardiograms acquired from monitoring electrode positions compared to standard locations.

We tested whether the "Lund" (LU) electrode-placement system compared to the Mason-Likar (M-L) electrode-placement system would produce waveforms more similar to those of standard electrocardiograms (ECGs) with regard to the QRS axis in the frontal plane and QRS changes of inferior myocardial infarction (MI). We also tested whether LU was more noise immune than standard, and whether the noise immu

Estimation of the Age-Dependent Decline of Glomerular Filtration Rate from Formulas Based on Creatinine and Cystatin C in the General Elderly Population.

Background/Aims: To evaluate the performance of estimation formulas for glomerular filtration rate (GFR) based on creatinine and cystatin C in elderly. Methods: This study includes 2,931 men and women comprising nine age cohorts (60-93 years) from a longitudinal population-based project in Sweden. The participants were divided into four age groups. GFR was estimated from four formulas: the Modific

Outcome after primary and secondary replacement for subcapital fracture of the hip in 10 264 patients.

Between 1999 and 2005, 10 264 patients who had undergone total hip replacement (THR) for subcapital fracture of the hip were compared with 76 520 in whom THR had been performed for other reasons. All the cases were identified through the Swedish Hip Arthroplasty Register. The THRs performed as primary treatment for fracture were also compared with those done after failure of internal fixation. Aft

Pharmacological normalization of circulation after acute brain death.

BACKGROUND: Circulatory instability is a serious problem after brain death in organ donors. The hypotension is often counteracted with infusion of large amounts of crystalloid solutions, which may impair lung function leading to rejection of the lungs as donor organs. The aim was to show that the circulation can be normalized pharmacologically for 24 h in pigs after total removal of the brain and

Transition from Acenocoumarol to Warfarin in a 12-year-old Child.

The types of coumadin anticoagulants registered and available for use differ between countries. Most frequently used coumadin anticoagulants are warfarin and acenocoumarol. Under several specific conditions, transition from one coumarin to another is required. Because of different pharmacokinetic and pharmacodynamic characteristics, the transition from one type of coumarol to another type can be c

Cognitive and executive functions in anorexia nervosa ten years after onset of eating disorder

In a longitudinal study, the authors explore the course of general cognition in anorexia nervosa (AN) over time and compare general cognitive problems, executive function deficits, attentional problems and visuomotor dysfunctions across AN individuals and healthy controls. A community-based sample of adolescent onset AN cases (n = 40-47) was contrasted with an age-, sex- and school matched compari

Isolation and generation of neurosphere cultures from embryonic and adult mouse brain.

Neural stem cells are defined as cells that either gives rise to or derives from the cells of the central nervous system and have the unique properties of stem cells, i.e. self-renewal and multipotentiality. One of the widely used methods of expanding neural stem cells under culture conditions is based on the capacity of these cells to divide continuously when cultured in serum-free medium supplem

Preterm birth and psychiatric medication prescription in young adulthood: a Swedish national cohort study.

BACKGROUND: Recent studies suggest an increased risk of adverse mental health outcomes among young adults who were born preterm. These studies have been based mainly on hospital data, thus missing large numbers of mental health problems that do not require inpatient treatment. We used national outpatient and inpatient pharmacy data to evaluate whether individuals who were born preterm were more li

Spectral asymptotics for higher-order ordinary differential equations

This paper gives one-term componentwise asymptotics for the M and spectral matrices of a self-adjoint realisation of an even-order ordinary differential expression. The underlying interval is assumed to have at least one regular endpoint, and the boundary conditions are supposed to be separated. Furthermore, the weight function and the reciprocal of the highest-order coefficient are supposed to be

Central projections of the sensory innervation of the rat middle meningeal artery.

Headaches, especially migraine, involve not only pain but also aspects such as vasodilation of cranial vessels and sensitization of nerve endings, processes dependent on and connected to the central nervous system. To understand pathogenic mechanisms of headache, it is important to elucidate the central projections of sensory nerves that innervate cranial vessels, of which the middle meningeal art
