ELISA on a microchip with a photodiode for detection of amphetamine in plasma and urine

A rapid and sensitive assay was developed for the detection of amphetamine in plasma and urine. The method relies on the principle of competitive ELISA (enzyme-linked immunosorbent assay). A flow microchip with a total volume of 7 µL was used for the development of a chemiluminescent ELISA technique. Solutions, samples, and the chemiluminescence substrate were injected by a flow system, and a phot

Associations of dietary fiber with glucose metabolism in nondiabetic relatives of subjects with type 2 diabetes - The Botnia Dietary Study

OBJECTIVE - To study cross-sectional associations of dietary fiber intake with insulin resistance, insulin secretion, and glucose tolerance in a population at high risk for type 2 diabetes. RESEARCH DESIGN AND METHODS - The subjects consisted of 248 male and 304 female adult nondiabetic relatives of patients with type 2 diabetes. Dietary intake was measured by means of two 3-day food records. Asso

Organic acid behaviour in a calcareous soil implications for rhizosphere nutrient cycling

Calcareous soils are frequently characterized by the low bioavailability of plant nutrients. Consequently, many vascular plant species are unable to successfully colonize calcareous sites and the floristic composition of calcareous and acid silicate soils has been shown to differ markedly. The root exudation of oxalate and citrate has been suggested to play a pivotal role in same nutrient acquisit

Doctors are more dangerous than gun owners: A rejoinder to error counting

Objective: This paper analyzes some of the problems with error counting as well as the difficulty of proposing viable alternatives. Background: Counting and tabulating negatives (e.g., errors) are currently popular ways to measure and help improve safety in a variety of domains. They uphold an illusion of rationality and control but may offer neither real insight nor productive routes for improvin

Modelling temperature dynamics of a district heating system in Naestved, Denmark – a case study

Modelling the temperature dynamics of a district heating system is typically validated for a single pipe or a system with limited information about dynamic consumer behaviour. In the present work, time dependent consumer data from the Naestved district heating system was used to investigate the ability of modelling tools to represent the temperature profile distortion throughout an entire heating

Supports made from recycled glass as biofilm carriers in anaerobic packed bed treatment of high-strength wastewaters

The possibility of using carriers made of recycled glass in anaerobic packed bed reactors has been studied in laboratory-scale experiments. Two types of carrier were studied: a porous bead of glass foam and an open ring of a smoother, sintered glass. The performance of processes with these carriers was compared with a conventional upflow anaerobic sludge blanket (UASB) process. The treatment of wa

Conversion and Contextual Conceptions of Christ: A Missiological Study among Young Converts in Brazzaville, Republic of Congo

Popular Abstract in Swedish Avhandlingen är baserad på forskning rörande sambandet mellan omvändelsemotiv och Kristusbild bland unga konvertiter i Brazzaville, Republiken Kongo. Förf. visar att samband föreligger och att de vanligaste Kristusföreställningarna kan relateras till två arketyper i kongolesiska traditionella trosföreställningar: nämligen broder-anfadern (Yaya) och häxdoktorn (nganga). This study presents contextual conceptions of Christ among young urban converts, within the Evangelical Church of Congo (EEC). The basic data consists of interviews, conversion stories, gathered during fieldwork in 1995-1997. From the data explicit and implicit conceptions of Christ were deducted and accounted for in the study. The main analytical questions are: How do young people (aged 17-35) co

Interligand electron transfer determines triplet excited state electron injection in RuN3-sensitized TiO2 films

Electron injection from the transition metal complex Ru(dcbpy)(2)(NCS)(2) (dcbpy = 2,2'-bipyridine-4,4'-dicarboxylate) into a titanium dioxide nanoparticle film occurs along two pathways. The dominating part of the electron injection proceeds from the initially excited singlet state of the sensitizer into the conduction band of the semiconductor on the sub-hundred-femtosecond time scale. The slowe

Characterisation of Urban Rainfall in Kuala Lumpur, Malaysia

Popular Abstract in Swedish Arbetet avser studier av regnkarakteristik i tid och rum i Kuala Lumpur, Malaysia. I storskalig betraktelse studerades ett 550 km2 område för att bl.a. finna påverkan av monsuner. I skalan av ett avrinningsområde avsåg arbetet en studie av regnets dynamiska egenskaper och rumsliga korrelationsstrukturer. I en enpunktskala, för ett 23 km2 stort område framtogs sannolikheRainfall characteristics of Kuala Lumpur, Malaysia, are studied in space and time; on a large scale, 550 km2, and long term scale to find out the monsoon influence, and on urban basin scale, 23 km2, to determine dynamic properties of rainfalls and spatial correlations, and on a point scale to determine the probabilities of very high rain intensities. The importance of spatial and temporal variabi

Effects of tiagabine, a gamma-aminobutyric acid re-uptake inhibitor, on normal rat bladder function.

PURPOSE: Previous reports have demonstrated the inhibitory effect of exogenous gamma-aminobutyric acid (GABA) on micturition. In the current study we tested whether tiagabine (Sanofi Synthelab., Newcastle-upon Tyne, United Kingdom), a GABA re-uptake inhibitor increasing endogenous GABA concentrations, would affect micturition in awake rats or influence rat detrusor contraction in vitro. MATERIALS

Attempt to establish a chronic model to study the influence of bile and pancreatic juice diversion on pancreas feedback regulation in conscious pigs

The diversion of pancreatic juice and bile stimulates pancreatic exocrine secretion but the mechanism behind this process is still not clear. The present study investigates the influence of long lasting (10 h) bile diversion or pancreatic juice and bile diversion on the pancreatic secretion in conscious pigs. The experiments were performed on 4 weaned piglets, which had a catheter inserted to the
