TRPV1 and TRPA1 stimulation induces MUC5B secretion in the human nasal airway in vivo.

Aim: Nasal transient receptor potential vanilloid 1 (TRPV1) stimulation with capsaicin produces serous and mucinous secretion in the human nasal airway. The primary aim of this study was to examine topical effects of various TRP ion channel agonists on symptoms and secretion of specific mucins: mucin 5 subtype AC (MUC5AC) and B (MUC5B). Methods: Healthy individuals were subjected to nasal challeng

The SELMA Study: A Birth Cohort Study in Sweden Following More Than 2000 Mother-Child Pairs.

Background: This paper describes the background, aim and study design for the Swedish SELMA study that aimed to investigate the importance of early life exposure during pregnancy and infancy to environmental factors with a major focus on endocrine disrupting chemicals for multiple chronic diseases/disorders in offspring. Methods: The cohort was established by recruiting women in the 10th week

Fracture mapping using seismic amplitude variation with offset and azimuth analysis at the Weyburn CO2 storage site

Cap rock integrity is an essential characteristic of any reservoir to be used for long-term CO 2 storage. Seismic AVOA (amplitude variation with offset and azimuth) techniques have been applied to map HTI anisotropy near the cap rock of the Weyburn field in southeast Saskatchewan, Canada, with the purpose of identifying potential fracture zones that may compromise seal integrity. This analysis, su

Between colourblindness and ethnicisation: Transnational adoptees and race in a Swedish context

When and how are issues of race and ethnicity articulated in the everyday lives of transnational adoptees in Sweden? Which discursive and practical ambivalences and conflicts do they provoke? What happens with issues of race in a country where antiracist colourblindness is the norm, and where there has been no debate on whether whites should adopt children of colour? Based on an analysis of interv

A bi-hyperbolic finite volume method on quadrilateral meshes

A non-oscillatory, high resolution reconstruction method on quadrilateral meshes in 2D is presented. It is a two-dimensional extension of Marquina's hyperbolic method. The generalization to quadrilateral meshes allows the method to simulate realistic flow problems in complex domains. An essential point in the construction of the method is a second order accurate approximation of gradients on an ir

Health-care quality registers: outcome-orientated ranking of hospitals is unreliable.

Public disclosure of outcome-orientated ranking of hospitals is becoming increasingly popular and is routinely used by Swedish health-care authorities. Whereas uncertainty about an outcome is usually presented with 95% confidence intervals, ranking's based on the same outcome are typically presented without any concern for bias or statistical precision. In order to study the effect of incomplete r

Reducing Unnecessary Biopsy During Prostate Cancer Screening Using a Four-Kallikrein Panel: An Independent Replication.

PURPOSE: We previously reported that a panel of four kallikrein forms in blood-total, free, and intact prostate-specific antigen (PSA) and kallikrein-related peptidase 2 (hK2)-can reduce unnecessary biopsy in previously unscreened men with elevated total PSA. We aimed to replicate our findings in a large, independent, representative, population-based cohort. PATIENTS AND METHODS: The study cohort

Lipomatous hypertrophy of the interatrial septum in a patient with carcinoma: a case report of the importanceof multi-modality imaging.

Introduction: Lipomatous hypertrophy of the interatrial cardiac septum is a benign disorder. In rare cases, the disorder can cause obstruction of atrial inflow, causing symptoms of heart failure, or cardiac arrhythmias resulting from the involvement of the atrial wall and atrioventricular conduction pathways. Case presentation: We present a case of a Caucasian 66-year-old man with urothelial carci

High Prevalence of Hypogonadism and Associated Impaired Metabolic and Bone Mineral Status in Subfertile Men.

It is yet unknown to which degree young subfertile men present with signs of hypogonadism and whether low testosterone concentration, like in older men, is associated with risk of osteoporosis and metabolic derangements in those subjects. The objective was, therefore, to investigate the prevalence of hypogonadism and its association with metabolic and bone parameters in young subfertile men.

Identification of Transplantable Dopamine Neuron Precursors at Different Stages of Midbrain Neurogenesis.

Protocols used for generation of mesencephalic dopamine (mesDA) neurons from stem cells, or fetal brain tissue, invariably result in cell preparations that are highly mixed in composition, containing mesDA neuron precursors in various states of fate commitment and differentiation. For further optimisation and refinement of these procedures it is essential to determine the optimal stage of developm

Variable velocity encoding in a three-dimensional, three-directional phase contrast sequence: Evaluation in phantom and volunteers.

PURPOSE: To evaluate accuracy and noise properties of a novel time-resolved, three-dimensional, three-directional phase contrast sequence with variable velocity encoding (denoted 4D-vPC) on a 3 Tesla MR system, and to investigate potential benefits and limitations of variable velocity encoding with respect to depicting blood flow patterns. MATERIALS AND METHODS: A 4D PC-MRI sequence was modified t

Climate sensitivity of Mediterranean pine growth reveals distinct east–west dipole

The European Mediterranean region is governed by a characteristic climate of summer drought that is likely to increase in duration and intensity under predicted climate change. However, large-scale network analyses investigating spatial aspects of pre-instrumental drought variability for this biogeographic zone are still scarce. In this study we introduce 54 mid- to high-elevation tree-ring width

Physical activity on prescription (PAP): Costs and consequences of a randomized, controlled trial in primary healthcare.

Abstract Objectives. To analyse costs and consequences of changing physical activity behaviour due to the "Physical Activity on Prescription" (PAP) programme. Design. A randomized controlled trial with a four-month intervention, with comparison between intervention and control group. Intervention. The PAP programme, with exercise twice a week, education, and motivational counselling. Subjects. 525
