Prussian blue modified glassy carbon electrodes - Study on operational stability and its application as a sucrose biosensor

Stabilisation of electrochemically deposited Prussian blue (PB) films on glassy carbon (GC) electrodes has been investigated and an enhancement in the stability of the PB films is reported if the electrodes are treated with tetrabutyl ammonium toluene-4-sulfonate (TTS) in the electrochemical activation step following the electrodeposition. A multi-enzyme PB based biosensor for sucrose detection wa

Characterisation of a cluster of TRIM-B30.2 genes in the chicken MHC B locus

We have identified and characterised a cluster of six TRIM-B30.2 genes flanking the chicken BF/ BL region of the B complex. The TRIM-B30.2 proteins are a subgroup of the TRIM protein family containing the tripartite motif ( TRIM), consisting of a RING domain, a B-box and a coiled coil region, and a B30.2-like domain. In humans, a cluster of seven TRIM- B30.2 genes has been characterised within the

Diabetes and impaired fasting glycemia in a rural population of Bangladesh

OBJECTIVE: To determine the prevalence of type 2 diabetes and impaired fasting glycemia (IFG) in a rural population of Bangladesh. RESEARCH DESIGN AND METHODS: A cluster sampling of 4,923 subjects >/=20 years old in a rural community were investigated. Fasting plasma glucose, blood pressure, height, weight, and girth of waist and hip were measured. BMI and waist-to-hip ratio (WHR) were calculated.

Sensitization and exposure to pet allergens in asthmatics versus non-asthmatics with allergic rhinitis

In sensitized subjects with allergic rhinitis (AR) or asthma, allergen exposure provokes symptoms. Among non-asthmatics with AR, an association between allergen sensitization, pollen season and lower airway inflammation has been demonstrated. Our aims were to compare AR and asthma with regard to patterns of allergen sensitization, the degree of airway hyperresponsiveness (AHR) and levels of exhale

Iterative joint detection, decoding and channel estimation for dual antenna arrays in frequency selective fading

Iterative receiver algorithms for multi-user detection and decoding are a solution for mitigating multiple-access interference in multiple access communication systems. After several iterations they outperform noniterative schemes, while maintaining modest complexity. In this paper, we present an iterative receiver for multiple-antenna systems in frequency selective fading. Channel knowledge is no

A new formula for the total longshore sediment transport rate

A new predictive formula for the total longshore sediment transport (LST) rate was developed from principles of sediment transport physics assuming that breaking waves mobilize the sediment, which is subsequently moved by a mean current. Six high-quality data sets on hydrodynamics and sediment transport collected during both field and laboratory conditions were employed to evaluate the predictive

High-level expression of active human cystatin C in Escherichia coli

Expression of the human cysteine proteinase inhibitor, cystatin C (CysC) in the cytoplasm of Escherichia coli was studied using a cDNA fragment encoding the cysteine proteinase inhibitor controlled by the phage λ pImage /cI857 system. The yield of CysC was low, probably due to proteolytic degradation. By fusing the cysC cDNA to a DNA fragment encoding the signal peptide of the E. coli outer membra

108Sn Studied with Intermediate-energy Coulomb Excitation

The unstable neutron-deficient Sn-108 isotope has been studied in inverse kinematics by intermediate-energy Coulomb excitation using the RISING/FRS experimental setup at GSI. This is the highest Z nucleus studied so far with this method. Its reduced transition probability B (E2;0(g.s.)(+)-> 2(1)(+)) has been measured for the first time. The extracted B(E2) value of 0.230(57)e(2) b(2) has been dete

Topical glucocorticosteroids in rhinitis: clinical aspects

The introduction of nasal glucocorticosteroids, 30 years ago, has been the most important therapeutic progress in rhinitis management since the introduction of the first generation of antihistamines. Our knowledge of the mode of action of glucocorticosteroids in the nose has improved as the airway mucous membrane of the nose is easily accessible for investigation. However, the exact mechanism behi

Bostadsbränder och sprinkler. En koppling till brandteknisk dimensionering

The aim of this study was to develop a model for the quantification of the occupant risk in residential fires. The model should make it possible to quantitatively evaluate which effect the presence of a residential sprinkler has on the fire development. Statistics on causes and outcomes of residential fires were used as background material for the model development. A literature review was carried

Risk of contact allergy and dermatitis at a wind turbine plant using epoxy resin-based plastics

Aims: To identify workplace and individual risk factors for occupational contact allergy and dermatitis. Methods: A cross-sectional study was carried out at an international company producing wind turbine systems in Denmark. A cohort of 724 production workers at four facilities was highly exposed to epoxy resin as well as other chemicals. A screening questionnaire (participation rate 84.7%) was fo

Leaching of hazardous substances from additives and admixtures in concrete

The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700
