Enzymatic Activity of Lipase-Nanoparticle Conjugates and the Digestion of Lipid Liquid Crystalline Assemblies

Variants of lipase were attached to gold nanoparticles (NPs) and their enzymatic activity was studied. The two bioengineered lipase variants have been prepared with biotin groups attached to different residues on the protein outer surface. The biotinylation was evidenced by denaturing polyacrylamide gel electrophoresis and quantified by the ([2-(4'-hydroxyazobenzene)]benzoic acid spectrophotometri

Recovery after total intravenous general anaesthesia or spinal anaesthesia for total knee arthroplasty: a randomized trial.

BACKGROUND: /st>This study was undertaken to compare the effects of general anaesthesia (GA) and spinal anaesthesia (SA) on the need for postoperative hospitalization and early postoperative comfort in patients undergoing fast-track total knee arthroplasty (TKA). METHODS: /st>One hundred and twenty subjects were randomly allocated to receive either intrathecal bupivacaine (SA group) or GA with tar

Prevalence of non-alcoholic fatty liver disease and its relation to hypoadiponectinaemia in the middle-aged and elderly Chinese population

Introduction: Hypoadiponectinaemia is an important risk factor for non-alcoholic fatty liver disease (NAFLD). However, little is known about its role in the Chinese population. This study sought to assess the prevalence of NAFLD and its association with hypoadiponectinaemia in middle-aged and elderly Chinese. Material and methods: We conducted a population-based cross-sectional study in an urban S

Research needs for incorporating the ecosystem service approach into EU biodiversity conservation policy

Using a range of different methods including extensive reviews, workshops and an electronic conference, 70 key research recommendations and 12 priority research needs to integrate the ecosystem services approach into biodiversity conservation policy and funding were identified by a cross-disciplinary group of over 100 scientists and 50 stakeholders, including research funders and policy-makers. Th

The physical environment of purpose-built and non-purpose-built supported housing for persons with psychiatric disabilities in Sweden.

The primary aim of the present study was to investigate if methods derived from environmental psychology can be used to study the qualities of the physical environment of supported housing facilities for persons with psychiatric disabilities. Three units of analysis were selected: the private area, the common indoor area, and the outdoor area. Expert assessments of 110 features of the physical env

Impact of wind turbine sound on annoyance, self-reported sleep disturbance and psychological distress

Purpose of the research: The present government in the Netherlands intends to realize a substantial growth of wind energy before 2020, both onshore and offshore. Wind turbines, when positioned in the neighborhood of residents may cause visual annoyance and noise annoyance. Studies on other environmental sound sources, such as railway, road traffic, industry and aircraft noise show that (long-term)

Simulation of the response of base-isolated buildings under earthquake excitations considering soil flexibility

The accurate analysis of the seismic response of isolated structures requires incorporation of the flexibility of supporting soil. However, it is often customary to idealize the soil as rigid during the analysis of such structures. In this paper, seismic response time history analyses of base-isolated buildings modelled as linear single degree-of-freedom (SDOF) and multi degree-of-freedom (MDOF) s

Stem cell factor receptor/c-Kit: from basic science to clinical implications

Lennartsson J, Ronnstrand L. Stem Cell Factor Receptor/c-Kit: From Basic Science to Clinical Implications. Physiol Rev 92: 1619-1649, 2012; doi: 10.1152/physrev.00046.2011.-Stem cell factor (SCF) is a dimeric molecule that exerts its biological functions by binding to and activating the receptor tyrosine kinase c-Kit. Activation of c-Kit leads to its autophosphorylation and initiation of signal tr

Dry-Reagent Double-Monoclonal Assay for Cystatin C

BACKGROUND: Cystatin C is a low molecular weight cysteine proteinase inhibitor whose plasma or serum concentrations have been shown to be better correlated with glomerular filtration rate than serum creatinine concentrations. Routine assays for cystatin C are based on use of polyclonal antibodies and immunoturbidimetric and nephelometric designs. This study aimed to develop a double-monoclonal imm

Validation of a Parental Questionnaire to Identify Atopic Dermatitis in a Population-Based Sample of Children up to 2 Years of Age.

Background: Validated eczema questionnaires have been available for schoolchildren only, but the incidence of atopic dermatitis (AD) is highest during infancy. Objective: To validate a parental questionnaire to identify AD in children up to 2 years of age. Methods: Parents of 476 children answered a written questionnaire prior to an examination by a physician. Sensitivity, specificity, predictive

Researchers’ Blogging Practices in Two Epistemic Cultures: The Scholarly Blog as a Situated Genre

This article presents a study of 16 scholarly blogs with the aim to gain an in-depth understanding of what characterizes blogging as part of the scholarly communication. Eight blogs from high energy physics (HEP) and eight from digital history were closely followed. The analysis was made by employing an analytical framework based on genre theory. The results reveal common communicative purposes in

The tagged photon facility at the MAX IV Laboratory

The upgraded tagged photon facility at the MAX IV Laboratory is presented. The pulsed electron beam from a linac system is stretched in the MAX I ring and the electron beam hits a thin aluminium foil in which bremsstrahlung is produced. One of two available magnetic spectrometers is used to determine the energy of the post-bremsstrahlung electrons. The tagged photon ranges from 10 to 180 MeV with

Role of non-coding RNAs in pancreatic beta-cell development and physiology.

The progression of diabetes is accompanied by increasing demand to the beta-cells to produce and secrete more insulin, requiring complex beta-cell adaptations. Functionally-active and ubiquitous non-coding RNAs (ncRNAs) have the capacity to take part in such adaptations as they have been shown to be key regulatory molecules in various biological processes. In the pancreatic islets, the function of

Gene expression identifies heterogeneity of metastatic propensity in high-grade soft tissue sarcomas

BACKGROUND: Metastatic propensity of soft tissue sarcoma (STS) is heterogeneous and may be determined by gene expression patterns that do not correlate well with morphology. The authors have reported gene expression patterns that distinguish 2 broad classes of clear cell renal carcinoma (ccRCC-gene set), and other patterns that can distinguish heterogeneity of serous ovarian carcinoma (OVCA-gene s

Prospects for detecting decreasing exoplanet frequency with main-sequence age using PLATO

The space mission PLATO will usher in a new era of exoplanetary science by expanding our current inventory of transiting systems and constraining host star ages, which are currently highly uncertain. This capability might allow PLATO to detect changes in planetary system architecture with time, particularly because planetary scattering due to Lagrange instability may be triggered long after the sy

Perceptions of innovativeness among Iranian hotel managers

Despite the undisputed importance of organizational innovation and decades of academic research on the subject, there is surprisingly little agreement on what innovativeness is or how to achieve successful innovation in practice. Furthermore, the difference between the theory and practice is often interpreted in an ad hoc manner, which limits the potential for innovation to provide a competitive a

Equation of State of Colloidal Dispersions.

We present a comparison of experimentally and theoretically determined osmotic pressures for various colloidal dispersions. Experimental data is collected from several different silica and polystyrene dispersions. The theoretical pressure determinations are based on the primitive model combined with the cell model, and the physical quantities are calculated exactly using Monte Carlo simulations in
