Halomonas boliviensis LC1 is able to accumulate poly(beta-hydroxybutyrate) (PHB) under conditions of excess carbon source and depletion of essential nutrients. This study was aimed at an efficient production of PHB by growing H. boliviensis to high cell concentrations in batch cultures. The effect of ammonium, phosphate, and yeast extract concentrations on cell concentration [cell dry weight (CDW)

This paper describes a new amperometric biosensor for glucose monitoring. The biosensor is based on the activity of glucose dehydrogenase (GDH) and diaphorase (DI) co-immobilized with NAD(+) into a carbon nanotube paste (CNTP) electrode modified with an osmium functionalized polymer. This mediator was demonstrated to shuttle the electron transfer between the immobilized diaphorase and the CNTP ele

The aim of the study was to investigate the feasibility of mobilizing Philadelphia chromosome negative (Ph-) blood stem cells (BSC) with intensive chemotherapy and lenograstim (G-CSF) in patients with CML in first chronic phase (CP1). During 1994-1999 12 centers included 37 patients 556 years. All patients received 6 months' IFN, stopping at median 36 (1-290) days prior to the mobilization chemoth

This study established the reliability of a novel upper-limb trajectory-tracking task for assessment of perceptual motor control in hemiparetic adults. Eleven persons with chronic poststroke hemiparesis (mean 58.6 months) and eleven nondisabled control subjects performed an elbow flexion-extension task against a low-resistance isotonic load at three speeds: 25degrees/s, 45degrees/s, and 65degrees/

This thesis explores the ritual dimensions of the mortuary practices in the late Mesolithic cemeteries at Skateholm in Southern Sweden and Vedbæk-Bøgebakken in Eastern Denmark. With a combination of methods and theories that all focus on the ritual practices as action, a new approach to burials in archaeology is proposed. Special attention is given to the treatment of the body after death, which i

Extraction constants for the solvent extraction of hydrofluosilicic acid with Alamine 336 have been determined. Two species were identified, (R3NH+ )2 SiF62- and R3NH+ HSiF6, whose respective extraction constants were determined to be log K21 = 7.42 and log K11 = 2.60. For the dissociation of hydrofluosilicic acid the activity coefficient model presented by Bromley was adapted to sulphuric acid an

The mechanism, thermodynamics and kinetics of light-induced cyclic electron transfer have been studied in a model energy-transducing system consisting of solubilized Rhodobacter sphaeroides reaction center/light harvesting-1 complexes (so-called core complexes), horse heart cytochrome c and a ubiquinone-0/ubiquinol-0 pool. An analysis of the steady-state kinetics of cytochrome c reduction by ubiqu

The effect of hydrophilically modified polystyrene, poly(styrene-g-poly(ethylene oxide)), P(S-g-PEC), on the viscosity of ACT oil-continuous microemulsions has been investigated as a function of PS and PEO chain lengths and PEO chain density. A series of polymers, P (S-g-PEO) with PEO chain lengths of 23 or 9, and different graft densities were synthesized by living radical polymerization. Thus, a

Eleven adults spontaneously-hypertensive male rats (SHR) were studied 22 h or 7 days after a 2 h unilateral occlusion of the right middle cerebral artery (MCA). Another 11 SHR were studied after 24 h or 7 days of permanent MCA ligation. The brain infarcts were significantly larger (P < 0.05) after permanent occlusion than after a 2 h occlusion. More extensive and widespread vasogenic oedema, emana

The development of this paper was inspired by the increase in the number of different eco-label like quality assurance schemes established in the European Union in the past few years. These schemes are flooding the market and the researchers raise the question, is there enough credibility in these schemes? This piece of research is based on 58 eco-labeling like food schemes and dissects them into

BACKGROUND: The clinically important Kidd (JK) blood group antigens are carried by the urea transporter in red cells. The rare Jk(a-b-) phenotype can be caused by homozygosity at the JK locus for a silent allele, JK: This phenotype has been recorded in many ethnic groups, but it is most abundant among people originating from the Polynesian Islands and Finland. The molecular basis for Jk(a-b-) is u

The five different CP conserving amplitudes for the decays K --> 3pi are calculated using Chiral Perturbation Theory. The calculation is made to next-to-leading order and includes full isospin breaking. The squared amplitudes are compared with the corresponding ones in the isospin limit to estimate the size of the isospin breaking effects. In this paper we add the radiative corrections to the earl
