Biosensor microprobe arrays for in vivo monitoring of neurotransmitters

Real-time monitoring of neurotransmitters is of utmost importance for understanding the functioning of the brain. Especially L-glutamate and choline play a major role in chemical signalling and are highly involved in cognitive functions such as learning, m ...

Quantitative characterization of a recombinant Pichia pastoris Mut+ strain secreting avidin using transient continuous cultures

Carmen Jungo

The objective of this thesis was to characterize the growth stoichiometry, the specific recombinant protein productivity and the regulation of the alcohol oxidase (AOX) enzyme of a Pichia pastoris Mut+ strain, performing conventional chemostat cultures and ...

Quantification of vitamin C in the rat brain in vivo using short echo-time 1H MRS

Rolf Gruetter

Both ultrashort echo-time STEAM and MEGA-PRESS-edited spectroscopy were used to validate noninvasive quantification of vitamin C (ascorbate) in the developing rat brain, where changes in ascorbate concentration have been reported. Despite strong overlap wi ...

Une petite partie de l’imaginaire médiéval, terré, pourrait-on dire, au fond d’un certain nombre de légendes, a survécu grâce à la tradition orale. Ainsi, en fonction des événements, les quelques survivants réservent encore, parfois, une surprise métaphori ...

In vivo 13C NMR assessment of brain glycogen concentration and turnover in the awake rat

Rolf Gruetter

Brain glycogen metabolism was recently observed in vivo and found to be very slow in the lightly alpha-chloralose anesthetized rat [J. Neurochem. 73 (1999) 1300]. Based on that slow turnover, the total glycogen content in the awake rat brain and its turnov ...

Characterization of iron and manganese precipitates from an in situ ground water treatment plant

Urs von Gunten

Aquifer samples from the precipitation zone of an in situ iron and manganese removal plant that was operated for 10 years were analyzed for iron and manganese minerals. Measurements were performed by various chemical extraction techniques (5 M HCl, 0.0081 ...

Arsenic adsorption and oxidation at manganite surfaces. 1. Method for simultaneous of determination of adsorbed and dissolved arsenic species

Janet Gordon Hering

Arsenic occurs in the +III oxidation state as a metastable species in oxic waters. Under oxic conditions, As(III) is both more mobile in natural waters and less efficiently removed by water treatment processes than As(V). Other oxidants, however, can react ...

Noninvasive measurements of [1-13C]glycogen concentrations and metabolism in rat brain in vivo

Rolf Gruetter

Using a specific 13C NMR localization method, 13C label incorporation into the glycogen C1 resonance was measured while infusing [1- 13C]glucose in intact rats. The maximal concentration of [1-13C]glycogen was 5.1 ± 0.6 μmol g-1 (mean ± SE, n = 8). During ...

1-Oxa-2,3-cyclohexadiene (\"2H-isopyran\"): a strained heterocyclic allene undergoing cycloaddition reactions with characteristic typo-, regio- and stereoselectivities

1-Oxa-2,3-cyclohexadiene (I) can be readily generated by treatment of 5-bromo-3,4-dihydro-2H-pyran with potassium tert-butoxide in the presence of 18-crown-6 and can be trapped with dienes or olefins. Thus, the treatment of I with furan gave 50% yield of D ...

Vitamin D status in the elderly: seasonal substrate deficiency causes 1,25-dihydroxycholecalciferol deficiency

Johan Auwerx

The seasonal variation of 25-hydroxycholecalciferol and 1,25-dihydroxycholecalciferol was analyzed in 240 elderly subjects (mean age: 78 yr) in Belgium. Serum 25-hydroxycholecalciferol was lowest from February until May (mean levels less than 25 nmol/L). S ...
