The importance of the molecular weight of ethyl cellulose on the properties of aqueous-based controlled release coatings

Previous investigations of aqueous based ethyl cellulose (EC) latex dispersions have mainly focused on the commercially available viscosity grade 20 cps. In this study, dispersions of EC with varying viscosity grades (which correspond to molecular weights), ranging from 4 to 100 cps, were produced and characterised. The dispersions showed particle sizes around 200 nm and highly negative ζ-potentia

Socio-demographic factors and long-term use of benzodiazepines in patients with depression, anxiety or insomnia

Former studies that have attempted to characterize individual socio-demographic factors associated with long-term benzodiazepine use were based on relatively small sample sizes and/or self-reported data. Our aim was to clarify this using large-scale primary health care data from Sweden. The present study covered 71 primary health care centres containing individual-level data from a total of 919, 9

Expression of STAT3 in Prostate Cancer Metastases

STAT3 and its upstream activator IL6R have been implicated in the progression of prostate cancer and are possible future therapeutic targets. We analyzed 223 metastatic samples from rapid autopsies of 71 patients who had died of castration-resistant prostate cancer (CRPC) to study protein and gene expression of pSTAT3 and IL6R. Immunohistochemical analysis revealed that 95% of metastases were posi

Synergistic effect of haloduracin and chloramphenicol against clinically important Gram-positive bacteria

The emergence of drug-resistant pathogens has triggered the search for more efficient antimicrobial agents and formulations for treatment of infections. In recent years, combination therapy has become one of the effective clinical practices in treating infections. The present study deals with the effect of haloduracin, a lantibiotic bateriocin and chloramphenicol against clinically important bacte

Cost dynamics in the deployment of photovoltaics : Insights from the German market for building-sited systems

In most studies on technology change, the analysis of cost reductions of new energy technologies has been narrow and has often neglected essential processes related to the deployment of new technologies, such as photovoltaics (PV). However, in the case of distributed PV systems, other costs than for the PV modules – aka the deployment or balance-of-system costs – are significant. This review study

Do the CAP subsidies increase employment in Sweden? estimating the effects of government transfers using an exogenous change in the CAP

This study evaluates the impact of agricultural subsidies (CAP) on employment outside the agricultural sector. A side-effect of the decoupling reform in 2005 was that Sweden introduced a grassland support which caused a redistribution of payments among regions. This heterogeneity in transfers is used to identify the effects of government transfers on regional labour markets. The effect on employme

Resonant core spectroscopies of the charge transfer interactions between C60 and the surfaces of Au(111), Ag(111), Cu(111) and Pt(111)

Charge transfer interactions between C60 and the metal surfaces of Ag(111), Cu(111), Au(111) and Pt(111) have been studied using synchrotron-based photoemission, resonant photoemission and X-ray absorption spectroscopies. By placing the X-ray absorption and valence band spectra on a common binding energy scale, the energetic overlap of the unoccupied molecular orbitals with the density of states o

Development of in situ product removal strategies in biocatalysis applying scaled-down unit operations

An experimental platform based on scaled-down unit operations combined in a plug-and-play manner enables easy and highly flexible testing of advanced biocatalytic process options such as in situ product removal (ISPR) process strategies. In such a platform, it is possible to compartmentalize different process steps while operating it as a combined system, giving the possibility to test and charact

Carbon dioxide narcosis : Influence of short-term high concentration carbon dioxide inhalation on EEG and cortical evoked responses in the rat

The effects of 1 min exposure to 80% CO2 inhalation was studied in rats under light general anaesthesia with N2O. It was found that 80% CO2 gave a rapid slowing of the EEG as well as a rapid decrease of the amplitude of cortical somatosensory evoked potentials. Only minor influences upon the blood pressure and heart rate were seen. The changes were found to be transient and most of the EEG effects

Occupational lung diseases : From old and novel exposures to effective preventive strategies

Occupational exposure is an important, global cause of respiratory disease. Unlike many other non-communicable lung diseases, the proximal causes of many occupational lung diseases are well understood and they should be amenable to control with use of established and effective approaches. Therefore, the risks arising from exposure to silica and asbestos are well known, as are the means of their pr

Regional Differences in the Prescription of Biologics for Psoriasis in Sweden : A Register-Based Study of 4168 Patients

Background: Observational studies suggest an inequitable prescription of biologics in psoriasis care, which may be attributed to geographical differences in treatment access. Sweden regularly ranks high in international comparisons of equitable healthcare, and is, in connection with established national registries, an ideal country to investigate potential inequitable access. Objective: The aim wa

Single versus serial measurements of neuron-specific enolase and prediction of poor neurological outcome in persistently unconscious patients after out-of-hospital cardiac arrest - A TTM-trial substudy

Background: Prediction of neurological outcome is a crucial part of post cardiac arrest care and prediction in patients remaining unconscious and/or sedated after rewarming from targeted temperature management (TTM) remains difficult. Current guidelines suggest the use of serial measurements of the biomarker neuron-specific enolase (NSE) in combination with other predictors of outcome in patients

Elevated ambulatory systolic-diastolic pressure regression index is genetically determined in hypertensive patients with coronary heart disease

Objectives: Ambulatory systolic-diastolic pressure regression index (ASDPRI) as a composite marker of cardiovascular (CV) properties is related to CV complications. However, genetic determinants of ASDPRI are not known. The aim of this study is to report the relationship between certain single nucleotide polymorphisms (SNP) and ASDPRI in hypertensive patients with CAD confirmed by coronary angiogr

The safety of introducing a new generation TAVR device : One departments experience from introducing a second generation repositionable TAVR

Background: In the evolving field of transcatheter aortic valve replacements a new generation of valves have been introduced to clinical practice. With the complexity of the TAVR procedure and the unique aspects of each TAVR device, there is a perceived risk that changing or adding a new valve in a department could lead to a worse outcome for patients, especially during the learning phase. The obj

Limited tumor tissue drug penetration contributes to primary resistance against angiogenesis inhibitors

Resistance mechanisms against antiangiogenic drugs are unclear. Here, we correlated the antitumor and antivascular properties of five different antiangiogenic receptor tyrosine kinase inhibitors (RTKIs) (motesanib, pazopanib, sorafenib, sunitinib, vatalanib) with their intratumoral distribution data obtained by matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI). In t

E-learning programs in oncology : A nationwide experience from 2005 to 2014

Background: E-learning is an established concept in oncological education and training. However, there seems to be a scarcity of long-term assessments of E-learning programs in oncology vis-á-vis their structural management and didactic value. This study presents descriptive, nationwide data from 2005 to 2014. E-learning oncology programs in chemotherapy, general oncology, pain management, palliat
