Blue flags", development of a short clinical questionnaire on work-related psychosocial risk factors - A validation study in primary care

Background: Working conditions substantially influence health, work ability and sick leave. Useful instruments to help clinicians pay attention to working conditions are lacking in primary care (PC). The aim of this study was to test the validity of a short "Blue flags" questionnaire, which focuses on work-related psychosocial risk factors and any potential need for contacts and/or actions at the

Downregulation of Thromboxane A2 Receptor Occurs Mainly via Nuclear Factor-KappaB Signaling Pathway in Rat Renal Artery

Thromboxane A2 (TXA2) acts on TXA2 receptors (TP) to regulate renal artery blood flow and subsequently contributes to the pathogenesis of renal ischemia. The present study was designed to examine if nuclear factor-kappaB (NF-B) signaling pathway is involved in the downregulation of TP receptors in rat renal artery. Rat renal artery segments were organ cultured for 6 or 24 h. Downregulation of TP r

Phosphatidylcholine hydroperoxide-induced THP-1 cell adhesion to intracellular adhesion molecule-1

The accumulation of phosphatidylcholine hydroperoxide (PCOOH), a primary oxidation product of phosphatidylcholine (PC), in blood plasma and tissues has been observed in various pathological conditions, including atherosclerosis. However, the biological roles of PCOOH in these conditions remain unknown. To estimate the atherogenicity of PCOOH, we evaluated the effect of PCOOH on THP-1 monocytic cel

Twisted nanoribbons from a RGD-bearing cholic acid derivative

In light of the biomedical interest for self-assembling amphiphiles bearing the tripeptide Arg-Gly-Gly (RGD), a cholic acid derivative was synthesized by introducing an aromatic moiety on the steroidal skeleton and the RGD sequence on the carboxylic function of its chain 17–24, thus forming a peptide amphiphile with the unconventional rigid amphiphilic structure of bile salts. In aqueous solution,

Simulation of aortopulmonary collateral flow in Fontan patients for use in prediction of interventional outcomes

Purpose: Patients with complex congenital heart disease may need to be converted to a Fontan circulation with systemic venous return surgically connected to the pulmonary circulation. These patients frequently form aortopulmonary collaterals (APC), that is arterial inflows to the pulmonary artery vascular tree. The aim of this study was to develop a method to calculate the effect of APC on the pul

Mixed micelles of oppositely charged poly(N-isopropylacrylamide) diblock copolymers

Mixed micelle formation between two oppositely charged diblock copolymers that have a common thermosensitive nonionic block of poly(N-isopropylacrylamide) (PNIPAAM) has been studied. The block copolymer mixed solutions were investigated under equimolar charge conditions as a function of both temperature and total polymer concentrations by turbidimetry, differential scanning calorimetry, two-dimens

In vivo retention of (18)F-AV-1451 in corticobasal syndrome

OBJECTIVE: To study the usefulness of (18)F-AV-1451 PET in patients with corticobasal syndrome (CBS).METHODS: We recruited 8 patients with CBS, 17 controls, 31 patients with Alzheimer disease (AD), and 11 patients with progressive supranuclear palsy (PSP) from the Swedish BioFINDER study. All patients underwent clinical assessment, (18)F-AV-1451 PET, MRI, and quantification of β-amyloid pathology.

Effect of Travel Speed on the Visual Control of Steering Toward a Goal

Previous studies have proposed that people can use visual cues such as the instantaneous direction (i.e., heading) or future path trajectory of travel specified by optic flow or target visual direction in egocentric space to steer or walk toward a goal. In the current study, we examined what visual cues people use to guide their goal-oriented locomotion and whether their reliance on such visual cu

Does Voluntary Governance Work? : Insights from Specialty Coffee

Jordbruket har en stor miljöbelastning, men är också alltmer centralt för att finna lösningar på hållbarhetsproblem. Ett angreppssätt för ökad hållbarhet är politisk styrning och reglering. I avhandlingen analyserar jag några frivilliga marknadsbaserade regleringar: certifiering och rapportering. Detta är regleringar som involverar företag och konsumenter. Jag har undersökt hur några sådana initiaAgricultural businesses contribute to sustainability problems, but they are also increasingly central to the effort to develop solutions. One way of moving toward sustainability is through regulatory governance. In this thesis, I analyze a tool of regulatory governance called voluntary market-based regulatory initiatives. Specifically, I investigate two types of initiatives, certification and disc

Cost-effectiveness of supported employment adapted for people with affective disorders

Objective: The individual enabling and support (IES) model was effective in gaining competitive employment for people with affective disorders compared with traditional vocational rehabilitation (TVR) services in a randomized controlled trial in a Swedish setting. The object of this study is to perform a cost-effectiveness analysis of IES comparing to TVR. Methods: We considered the costs of inter

Time to awakening after cardiac arrest and the association with target temperature management

Aim: Target temperature management (TTM) at 32-36 °C is recommended in unconscious survivors of cardiac arrest. This study reports awakening in the TTM-trial. Our predefined hypotheses were that time until awakening correlates with long-term neurological outcome and is not affected by level of TTM. Methods: Post-hoc analysis of time until awakening after cardiac arrest, its association with long-t

Severe insulin-resistant diabetes due to insulin antibodies associated with eosinophilia

A 66-year-old man with type 2 diabetes on hemodialysis treatment was admitted due to poor glycemic control. His serum insulin level and the 125I-insulin binding rate were extremely high with an increased eosinophil count, although he did not have an allergic reaction to insulin or an elevation of specific IgE for human insulin. A Scatchard analysis revealed that the patient’s insulin antibodies ha

Comparison of three α-glucosidase inhibitors for glycemic control and bodyweight reduction in Japanese patients with obese type 2 diabetes

Aims/Introduction: α-Glucosidase inhibitors (αGIs) are widely used for the primary treatment of type 2 diabetes. We compared the clinical effects of three αGIs (miglitol, acarbose and voglibose) in patients with obese type 2 diabetes. Materials and Methods: Japanese patients (n = 81) with obese type 2 diabetes (body mass index [BMI] ≥25 kg/m2) were enrolled in this multicenter, open-label study. T

Association of glycated albumin with the presence of carotid plaque in patients with type 2 diabetes

Aims/Introduction: Postprandial hyperglycemia is a potent risk factor for cardiovascular disease. Serum glycated albumin (GA) has been reported to reflect postprandial blood glucose fluctuations. In the present study, we assessed the possible correlation of GA with the presence of carotid plaque to evaluate the potential clinical usefulness of GA for predicting atherosclerotic cardiovascular compl

Identifying the Authors’ National Variety of English in Social Media Texts

In this paper, we present a study for the identification of authors’ national variety of English in texts from social media. In data from Facebook and Twitter, information about the author’s social profile is annotated, and the national English variety (US, UK, AUS, CAN, NNS) that each author uses is attributed. We tested four feature types: formal linguistic features, POS features, lexicon-based
