Physiological influence of basic perturbations assessed by non-invasive optical techniques in humans

New non-invasive techniques enabling frequent or continuous assessments of various pathophysiological conditions might be used to improve in-hospital outcome by enabling earlier and more reliable bedside detection of medical deterioration. In this preclinical study, three modern non-invasive optical techniques, laser Doppler imaging (LDI), near-infrared spectroscopy (NIRS), and tissue viability im

High frequency QRS electrocardiogram analysis during exercise stress testing for detecting ischemia

Introduction ECG stress testing is an inexpensive and non-invasive detector of myocardial ischemia; addition of high-frequency QRS analysis (HFQRS) may improve accuracy. This study compared HFQRS during exercise in patients with and without ischemia as defined by multiple criteria. Material and methods High-resolution ECGs were recorded for 139 patients undergoing T99-sestamibi/T201-thallium stre

Appropriating Facebook : Enacting Information Literacies

The aim of this paper is to describe and analyse the repurposing of Facebook into a tool for learning in teacher training, and how information literacies are enacted in the process. The study is informed by a socio-cultural view on information literacy which implies that learning and literacies are situated, tool-based practices. An ethnographic study of a Facebook Group with two hundred Swedish

Performance of mutation pathogenicity prediction methods on missense variants.

Single nucleotide polymorphisms (SNPs) are the most common form of genetic variation in humans. The number of SNPs identified in the human genome is growing rapidly, but attaining experimental knowledge about the possible disease association of variants is laborious and time-consuming. Several computational methods have been developed for the classification of SNPs according to their predicted pat

Array-CGH identifies cyclin D1 and UBCH10 amplicons in anaplastic thyroid carcinoma.

Anaplastic thyroid cancer (ATC) is a rare but highly aggressive disease with largely unexplained etiology and molecular pathogenesis. In this study, we analyzed genome-wide copy number changes, BRAF (V-raf sarcoma viral oncogene homolog B1) mutations, and p16 and cyclin D1 expressions in a panel of ATC primary tumors. Three ATCs harbored the common BRAF mutation V600E. Using array-comparative geno

Advances in understanding l-DOPA-induced dyskinesia.

The crucial role of dopamine (DA) in movement control is illustrated by the spectrum of motor disorders caused by either a deficiency or a hyperactivity of dopaminergic transmission in the basal ganglia. The degeneration of nigrostriatal DA neurons in Parkinson's disease causes poverty and slowness of movement. These symptoms are greatly improved by pharmacological DA replacement with l-3,4-dihydr

Precision of measurements of physical workload during standardized manual handling part III: Goniometry of the wrists.

Goniometry of the wrist is a feasible method for studying wrist movements in most hand-intensive work. The precision and accuracy of the method per se is good. For the knowledge on validity of field measurements, the size of imprecision is of importance. This study evaluated this condition during standardized circumstances. Six women performed three different hand-intensive work tasks: 'materials

The anti-angiogenic peptide anginex greatly enhances Galectin-1 binding affinity for glycoproteins

Angiogenesis is a key event in cancer progression and therefore a promising target in cancer treatment. Galectin-1, a β-galactoside binding lectin, is up-regulated in the endothelium of tumors of different origin and has been shown to be the target for anginex, a powerful anti-angiogenic peptide with anti-tumor activity. Here we show that when bound to anginex, galectin-1 binds various glycoprotei

Primary aldosteronism among newly diagnosed and untreated hypertensive patients in a Swedish primary care area.

Abstract Objective. To evaluate the prevalence of primary aldosteronism (PA) in newly diagnosed and untreated hypertensive patients in primary care using the aldosterone/renin ratio (ARR), and to assess clinical and biochemical characteristics in patients with high and normal ARR. Design. Patient survey study. Setting and subjects. A total of 200 consecutive patients with newly diagnosed and untre

Ethical issues in physiotherapy - Reflected from the perspective of physiotherapists in private practice.

Background: An important aspect of physiotherapy professional autonomy is the ethical code of the profession, both collectively and for the individual member of the profession. The aim of this study is to explore and add additional insight into the nature and scope of ethical issues as they are understood and experienced by Danish physiotherapists in outpatient, private practice. Methods: A qu

Riboflavin and Ultraviolet A Collagen Crosslinking of the Cornea for the Treatment of Keratitis.

PURPOSE:: To describe riboflavin and ultraviolet light (UV) collagen crosslinking as an effective treatment for infectious keratitis. METHODS:: A 25-year-old previously healthy female contact lens user was diagnosed with unilateral severe keratitis with unclear pathogenesis, although the clinical presentation suggested acanthamoeba as the infectious agent. A 4-mm diameter, annular, semi-opaque inf

Induction of apoptosis by staurosporine involves the inhibition of expression of the major cell cycle proteins at the G(2)/m checkpoint accompanied by alterations in Erk and Akt kinase activities.

BACKGROUND: Staurosporine is a therapeutic agent that inhibits tumor cell growth by inducing cell death via intrinsic apoptotic pathways. Our previous studies in clinical settings have suggested that certain subpopulations of patients with acute myeloid leukemia (AML) had poor response to chemotherapy. MATERIALS AND METHODS: The effect of staurosporine on apoptosis and cell cycle distribution in h

TPS, CA 19-9, VEGF-A, and CEA as Diagnostic and Prognostic Factors in Patients with Mass Lesions in the Pancreatic Head.

Introduction: Although numerous tumour markers are available for periampullary tumours, including pancreatic cancer, their specificity and sensitivity have been questioned.Materials and methods: To assess the diagnostic and prognostic values of tissue polypeptide specific antigen (TPS), carbohydrate antigen 19-9 (CA 19-9), vascular endothelial growth factor (VEGF-A), and carcinoembryonic antigen (

Demonstration of functionally different interactions between phospholipase C-gamma and the two types of platelet-derived growth factor receptors

Phosphorylated tyrosine residues in receptor tyrosine kinases serve as binding sites for signal transduction molecules. We have identified two autophosphorylation sites, Tyr-988 and Tyr-1018, in the platelet-derived growth factor (PDGF) alpha-receptor carboxyl-terminal tail, which are involved in binding of phospholipase C-gamma (PLC-gamma). The capacities of the Y988F and Y1018F mutant PDGF alpha

Sperm DNA Integrity in Men Treated for Childhood Cancer.

PURPOSE: It is unknown whether childhood cancer and its treatment are associated with sperm DNA damage, which subsequently affects fertility and might be transmitted to the offspring. The aim of this study was to assess DNA fragmentation index (DFI) as an indicator of sperm DNA integrity in childhood cancer survivors (CCS), treatment regimen taken into account.EXPERIMENTAL DESIGN: In 99 CCS and 19
