I en ny stor, randomiserad interventionsstudie (ADVANCE) har man med aktiv behandling (perindopril/indapamid) jämfört med placebo nu fått otvetydiga resultat som visar att en skärpt blodtryckssänkning hos typ 2-diabetiker ger kliniska vinster. Vid en genomsnittlig tryckskillnad på 5,6/2,2 mm Hg (med ett medelblodtryck på 135/78 mm Hg i aktiva gruppen vid studiens slut) uppnåddes signifikanta effek

Background. There is an ongoing controversy regarding how to take care of patients with mild primary hyperparathyroidism (PHPT) and how to grade their disease activity in terms of bone parameters. This prospective and randomized study was undertaken to evaluate skeletal effects of delayed surgical treatment in such patients. Methods. Fifty patients with mild PHPT (serum calcium, 2.55 to 2.95 mmol/

Techniques for estimation of element levels directly in humans (noninvasive in vivo) or in samples (in vitro) from humans are reviewed. Toxic, nonessential, trace elements may cause temporary or permanent damage to various organs and tissues in humans. There is thus a need to control the concentrations. Knowledge of the relations between toxic effects and element concentration may be extracted fro

Two hundred apparently healthy sexually active women, 17-34 years of age, who had presented for a general health check-up at the Clinic of Dermatology and Venereology, Medical University, Plovdiv, Bulgaria, were asked about genital symptoms, sexual behaviour, contraceptive use and smoking habits, and examined for signs of genital infections. They were searched for genital chlamydial infection, gon

We present a unified approach for calculating the properties of shallow donors inside or outside heterostructure quantum wells. The method allows us to obtain not only the binding energies of all localized states of any symmetry, but also the energy width of the resonant states which may appear when a localized state becomes degenerate with the continuous quantum well subbands. The approach is non

Popular Abstract in Swedish Denna studie handlar om sysselsättningsintegrationen av manliga och kvinnliga invandrare i Sverige mellan 1970 och 1995. Första kapitlet inleds med en översikt av teorier och tidigare studier om invandrares sysselsättning. Utifrån denna formuleras ett antal hypoteser. Det andra kapitlet ger en översikt av den svenska migrationshistorien, invandrarnas karaktäristika samtThis study deals with the employment integration of immigrant men and women in Sweden between 1970 and 1995. The first chapter starts with a review of theory and previous studies on immigrant employment and from this a number of testable hypotheses are framed The second chapter gives an overview of Swedish immigration history, the composition of the immigrant population and the economic background

Source-sorted municipal organic waste from different dwelling types in five Danish cities was sampled during one year. The samples were from permanent, full-scale systems or temporary, experimental systems for collection of source-sorted municipal organic waste. Pre-treatment of the organic waste prior to biological treatment was used in all cities to remove foreign objects and provide size reduct

Three new diarylheptanoids, (4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-4,6-dien-3-one, letestuianin A (1), (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-4,6-dien-3-one, letestuianin B (2), and 1,7-bis(4-hydroxyphenyl)heptan-3,5-dione, letestuianin C (3), as well as the known (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxyphenyl)hepta-4,6-dien-3-one (5) were isolated f

The energy transfer within a series of Zn-porphyrin appended dendrimers was studied by means of time-resolved fluorescence anisotropy. We show that the energy transfer process between the Zn-porphyrin units in the dendrimers is limited to a maximum of four porphyrin units. At 200 K, the energy transfer process takes place on a 100-ps time scale, and can be modeled by Forster theory. Our results at

Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters. The research is presented in the form of five sc

This study presents a simple and rapid solvent exchange procedure using a hollow fiber. Antioxidants (Irganox 1010, Irganox 1076 and Irgafos 168) and solvents such as tetrahydrofuran (THF), carbon tetrachloride and toluene were selected as model compounds and sample solvents, respectively. After injection of the sample solution into the hollow fiber and solvent evaporation, the precipitated analyt

Multiphase clock generators are conventionally implemented with a feedback loop. This paper presents a non-feedback approach to generate multiphase clocks. A simple architecture of direct phase interpolation is proposed, in which the edges of two phase-adjacent signals are used to control the discharge (or charge) of two capacitors respectively, producing time-overlapped slopes. A resistor chain c

The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision is required Before the measurements, the fibre samples were dried in an oven at
