Regional differences in air velocity of microclimate inside clothing and bellows effect
Despite of a crucial role of microclimate inside clothing in thermal comfort, air velocity inside clothing has been hardly reported, ever since Lewis et al (1969) demonstrated that air velocity of the still air layer on the naked human body was 0.25 m/s using colour schlieren cinephotography. This study was aimed to investigate the air velocity of microenvironment inside clothing and the bellows e
MRI of the swallow tail sign : A useful marker in the diagnosis of lewy body dementia?
BACKGROUND AND PURPOSE: There are, to date, no MR imaging diagnostic markers for Lewy body dementia. Nigrosome 1, containing dopaminergic cells, in the substantia nigra pars compacta is hyperintense on SWI and has been called the swallow tail sign, disappearing with Parkinson disease. We aimed to study the swallow tail sign and its clinical applicability in Lewy body dementia and hypothesized that
Screening method for evaluation of inhibition of nitrification in Sweden
An investigation with respect to inhibition of nitrification of wastewater from 109 Swedish municipal wastewater treatment plants was performed. Flow proportional, 24-hour composite samples were collected during one week, and then analysed using the screening method. Inhibition of nitrification above 10% was found at only 20 plants. In general, the load of inhibiting substances is limited in Swedi
Improved molecular recognition of Carbonic Anhydrase IX by polypeptide conjugation to acetazolamide
The small molecule inhibitor acetazolamide (AZM) was conjugated to a set of designed polypeptides and the resulting conjugates were evaluated for their affinity to Human Carbonic Anhydrase II (HCA II) using surface plasmon resonance. The dissociation constant of the AZM-HCA II complex was 38. nM and that of the AZM conjugated polypeptide (4-C10L17-AZM) to HCA II was found to be 4. nM, an affinity
Optimum design of distributed energy hubs using hybrid surrogate models (HSM)
The energy hub concept is gradually getting popular due to its capability to integrate renewable energy technologies into the energy grid with a minimum impact. Designing distributed energy hubs is a challenging task due to the coupling of optimum dispatch and energy system sizing problems. Operation of the system needs to be considered for 8760 time steps and energy system sizing optimization can
Increased CXCL8 expression is negatively correlated with the overall survival of patients with ER-negative breast cancer
Background: C-X-C motif chemokine ligand 8 (CXCL8) is a multi-functional chemokine and has important roles during tumor formation and development. It was previously reported that increased CXCL8 protein levels occurred in certain patients. Materials and Methods: In the present study, we examined levels of CXCL8 mRNA in breast cancer tissues and analyzed its levels in correlation to patients' clini
Perspective : An extension of the STROBE statement for observational studies in nutritional epidemiology (STROBE-nut): Explanation and elaboration
Nutritional epidemiology is an inherently complex and multifaceted research area. Dietary intake is a complex exposure and is challenging to describe and assess, and links between diet, health, and disease are difficult to ascertain. Consequently, adequate reporting is necessary to facilitate comprehension, interpretation, and generalizability of results and conclusions. The STrengthening the Repo
The Internationalization of Vietnamese SMEs
Small and medium-sized enterprises (SMEs) have been important for Vietnam's rapid economic development. This paper investigates the ways in which Vietnam's SMEs have been affected by the ongoing internationalization of the Vietnamese economy and points out the challenges that lie ahead if the country's plans for further trade liberalization are realized. The basis of our analysis is a unique datab
Transcriptional profiling reveals functional dichotomy between human slan+ non-classical monocytes and myeloid dendritic cells
Human 6-sulfo LacNac-positive (slan+) cells have been subject to a paradigm debate. They have previously been classified as a distinct dendritic cell (DC) subset. However, evidence has emerged that they may be more related to monocytes than to DCs. To gain deeper insight into the functional specialization of slan+ cells, we have compared them with both conventional myeloid DC subsets (CD1c+ and CDHuman 6-sulfo LacNac-positive (slan+) cells have been subject to a paradigm debate.

Probing RbBr solvation in freestanding sub-2 nm water clusters
Concentration dependent solvation of RbBr in freestanding sub-2 nm water clusters was studied using core level photoelectron spectroscopy with synchrotron radiation. Spectral features recorded from dilute to saturated clusters indicate that either solvent shared or contact ion pairs are present in increasing amount when the concentration exceeds 2 mol kg-1. For comparison, spectra from anhydrous R
The prevalence, incidence, and progression of hand osteoarthritis in relation to body mass index, smoking, and alcohol consumption
Objective. To estimate the extent that overweight/obesity, smoking, and alcohol are associated with prevalence and longitudinal changes of radiographic hand osteoarthritis (OA). Methods. Participants from the Osteoarthritis Initiative (n = 1232) were included, of whom 994 had 4-year followup data. In analyses on incident hand OA, only persons without hand OA at baseline were included (n = 406). Ou
Is there Really a Foreign Ownership Wage Premium? : Evidence from Matched Employer-Employee Data
Numerous studies on firm-level data have reported higher average wages in foreign-owned firms than in domestically owned firms. This, however, does not necessarily imply that the individual worker's wage increase with foreign ownership. Using detailed matched employer–employee data on the entire Swedish private sector, we examine the effect of foreign ownership on individual wages, controlling for
Asporin-deficient mice have tougher skin and altered skin glycosaminoglycan content and structure
The main structural component of connective tissues is fibrillar, cross-linked collagen whose fibrillogenesis can be modulated by Small Leucine-Rich Proteins/Proteoglycans (SLRPs). Not all SLRPs’ effects on collagen and extracellular matrix in vivo have been elucidated; one of the less investigated SLRPs is asporin. Here we describe the successful generation of an Aspn-/- mouse model and the inves
Recombinant factor VIIa use in acute type A aortic dissection repair : A multicenter propensity-score-matched report from the Nordic Consortium for Acute Type A Aortic Dissection
Background: Surgery for acute type A aortic dissection (ATAAD) is often complicated by excessive bleeding. Recombinant factor VIIa (rFVIIa) effectively treats refractory bleeding associated with ATAAD surgery; however, adverse effects of rFVIIa in these patients have not been fully assessed. Here we evaluated rFVIIa treatment in ATAAD surgery using the Nordic Consortium for Acute Type A Aortic Dis
Myocardium at risk assessed by electrocardiographic scores and cardiovascular magnetic resonance - a MITOCARE substudy
Introduction: The myocardium at risk (MaR) represents the quantitative ischemic area destined to myocardial infarction (MI) if no reperfusion therapy is initiated. Different ECG scores for MaR have been developed, but there is no consensus as to which should be preferred. Objective: Comparisons of ECG scores and Cardiac Magnetic Resonance (CMR) for determining MaR. Methods: MaR was determined by 3
Stimulation of nerve regeneration by macrophages in granulation tissue
The effects of granulation tissue exposure on regeneration of sensory axons after a test crush lesion in rat sciatic nerves were studied. Chromic catgut threads were applied subcutaneously in the back of rats. Three weeks later the surrounding granulation tissue was isolated and transposed to the sciatic or tibial nerve in the same rat. Immunocytochemical, light and electron microscopic evaluation
Regeneration across a partial defect in rat sciatic nerve encased in a silicone chamber
Forty-four rat sciatic nerves with partial defects were repaired with a silicone chamber. Each partial defect was created by resecting a 10 mm segment from the tibial fascicle leaving the peroneal fascicle intact. The proximal and the distal stumps of the tibial fascicle together with the intact peroneal fascicle were encased in a single silicone chamber. After seven days a fibrin matrix had surro
An Anatomically Constrained Model for Path Integration in the Bee Brain
Path integration is a widespread navigational strategy in which directional changes and distance covered are continuously integrated on an outward journey, enabling a straight-line return to home. Bees use vision for this task-a celestial-cue-based visual compass and an optic-flow-based visual odometer-but the underlying neural integration mechanisms are unknown. Using intracellular electrophysiol
