Differential expression of osteopontin and bone sialoprotein in bone metastasis of breast and prostate carcinoma

Breast and prostate cancer often metastasise to the skeleton. Interestingly, the histopathological characteristics of the bone lesions that arise from these two cancer types differ. Breast tumours give rise to metastases in the skeleton with a mixed lytic/sclerotic pattern, whereas a predominantly sclerotic pattern is seen in metastases from prostate tumours. Osteopontin (OPN) and bone sialoprotei

Concealed conduction and dual pathway physiology of the atrioventricular node

AV Nodal Duality and Concealment. Introduction: Both concealed conduction and dual pathway physiology are important electrophysiologic characteristics of the AV node. The interaction of AV nodal concealment and duality, however, is not clearly understood. Methods and Results: The properties of AV conduction curves in the presence and absence of a conditioning blocked impulse were prospectively stu

Slepian models for chi²-processes with dependent components with application to envelope upcrossings

A Slepian model for the local behaviour near the level upcrossings of a chi²-process with dependent Gaussian components is presented. In case of independent components, this model is shown to take on a rather simple form, thereby simplifying earlier results by Aronowich and Adler. The Slepian model is applied to the envelope of a stationary Gaussian process and used to approximate the probabilit

Socioeconomic position, macroeconomic environment and overweight among adolescents in 35 countries

Objective: It is important to understand levels and social inequalities in childhood overweight within and between countries. This study examined prevalence and social inequality in adolescent overweight in 35 countries, and associations with macroeconomic factors. Design: International cross-sectional survey in national samples of schools. Subjects: A total of 11-, 13- and 15-year-olds from 35 co

Structures and stabilities of Cd(II) and Cd(II)-phthalate complexes at the goethite/water interface

The complexation of Cd(II) and Cd(II)-phthalate at the goethite/water interface were investigated by EXAFS and IR spectroscopy, by batch adsorption experiments and by potentiometric titrations at 298.15 K. The EXAFS spectra showed Cd(IT) to form only inner-sphere corner-sharing complexes with the goethite surface sites in the presence and absence of phthalate. EXAFS spectra also showed the presenc

Fracture incidence in GH-deficient patients on complete hormone replacement including GH

Fracture risk in GHD patients is not definitely established. Studying fracture incidence in 832 patients on GH therapy and 2581 matched population controls, we recorded a doubled fracture risk in CO GHD women, but a significantly lower fracture risk in AO GHD men. Introduction: The objective of this study was to evaluate fracture incidence in patients with confirmed growth hormone deficiency (GHD)

Astrophysical Lasers with Radiation Pumping by Accidental Resonance

In this paper we consider a general problem of astrophysical lasersoperating with optical pumping by accidental resonance (PAR) with strongspontaneous emission lines of other elements. The origin of populationinversion and the coefficient of amplification due to the opticalexcitation of atoms (ions) by a four-level scheme with PAR are analyzed.We elucidate conclusively the question of the manifest

Symmetry measures of vestibular evoked myogenic potentials using objective detection criteria

Vestibular evoked myogenic potentials (VEMP) has been put forward as a test to evaluate the symmetry of saccular function. In the present study, the symmetry of VEMP was evaluated in 23 healthy subjects using automatic analysis. In response to binaural clicks with a stimulus repetition rate of 4/s all subjects revealed significant VEMP on both sides. The ipsilateral response to monaural clicks was

Everyday ethics in the care of elderly people

This article analyses the general ethical milieu in a nursing home for elderly residents and provides a decision-making model for analysing the ethical situations that arise. It considers what it means for the residents to live together and for the staff to be in ethically problematic situations when caring for residents. An interpretative phenomenological approach and Sandman’s ethical model prov

2D-temperature imaging of single droplets and sprays using thermographic phosphors

A novel 2D-technique for temperature visualization of single droplets and sprays is presented. Laser induced emission from thermographic phosphor seeded to the investigated liquid was detected by a fast framing camera. The subsequent phosphorescence images measured by seven consecutively gated CCD detectors allowed pixel-to-pixel lifetime evaluation of the phosphorescence emission. The temperature

Traveling waves in compressible elastic rods

We determine all weak traveling wave solutions of a model for nonlinear dispersive waves in cylindrical compressible hyperelastic rods. Besides the previously known smooth, peaked, and cusped solutions, the equation is shown to admit compactons, stumpons, and fractal-like waves.

A multi-intervention approach on drug therapy can lead to a more appropriate drug use in the elderly. LIMM-Landskrona Integrated Medicines Management

Rationale, aims and objectives To evaluate if an integrated medicines management can lead to a more appropriate drug use in elderly inpatients. Method The study was an intervention study at a department of internal medicine in southern Sweden. During the intervention period pharmacists took part in the daily work at the wards. Systematic interventions aiming to identify, solve and prevent drug-rel

An introduction to the South Swedish Apparent Cleft (SSAC)

Abstract: In this paper, the South Swedish Apparent Cleft (SSAC) is introduced, described and briefly discussed. The SSAC was first observed in the 1940s, and it has not yet been subject to any detailed linguistic analysis. The usage of the SSAC has been examined in a corpus study and via a questionnaire, and the results suggest (albeit inconclusively) that it truly is a specifically south Swedish

Stimulation of vascular protein synthesis by activation of oestrogen receptor beta

The objective of this study was to investigate the effects of oestrogen receptor (ER) beta activation on vascular protein synthesis and protein expression. Nuclear immunoreactivity towards ER beta was observed abundantly in vascular smooth muscle and endothelial cells of mouse aorta. No ER alpha-positive cell nuclei were observed. In aorta from ovariectomized mice, treatment with the selective ER

Evidence that vildagliptin attenuates deterioration of glycaemic control during 2-year treatment of patients with type 2 diabetes and mild hyperglycaemia

Aim: To assess the 2-year efficacy and tolerability of vildagliptin (50 mg once daily) in patients with type 2 diabetes (T2DM) and mild hyperglycaemia. Methods: This was a multicentre, randomized, double-blind, placebo-controlled trial comprising a 52-week core study with a 4-week, active treatment-free washout followed by a 52-week extension study with another washout period conducted in 131 drug

Aggregate manganese Schiff base moieties by terephthalate or acetate: Dinuclear manganese and trinuclear mixed metal Mn-2/Na complexes

A reaction system consisting of terephthalic acid, NaOH, inorganic Mn(II) or Mn(III) salt, and salicylidene alkylimine resulted in dinuclear manganese complexes (salpn)(2)Mn-2(mu-phth)(CH3OH)(2) (1, salpn = N,N'-1,3-propylene-bis(salicylideneiminato); phth = terephthalate dianion), (salen)(2)Mn-2(mu-phth)(CH3OH)(2) (2, salen = N,N'-ethylene-bis(salicylideneiminato)), (salen)(2)Mn-2(mu-phth)(CH3OH)

Analysis of surface electrocardiograms in atrial fibrillation: techniques, research, and clinical applications

Atrial. fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy is sufficiently predictable by clinical and echocardiographic parameters. The purpose of this article is to describe technical aspects of novel electrocardiogram (ECG) analysis techniques and to present research and clinical applications of these m
