The four major oligomeric reaction products from saponified modified hairy regions (MHR-S) from apple, produced by recombinant rhamnogalacturonan (RC) alpha-L-rhamnopyranosyl-(1,4)-alpha-D-galactopyranosyluronide lyase (rRG-lyase) from Aspergillus aculeatu ...
Metabolite signals with short T1 or T2 are difficult to localize with full sensitivity. This limitation was overcome with the development and implementation of a single-shot, complete three-dimensional 'non-echo' localization method with reduced sensitivit ...
Bench-scale heat flux calorimetry is applied to monitor complex microbial systems producing secondary metabolites and having a rheol. complex behavior. With such systems, biol. metabolic activity can only be measured accurately if calorimetry is improved b ...
The formation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) and 2(or 5)-ethyl-4-hydroxy-5(or 2)-methyl-3(2H)-furanone (EHMF) from pentose sugars was studied in Maillard model systems. The amts. generated at 90 DegC for 1 h were detd. by isotope diln. ass ...
Adenosine triphosphate (ATP) promotes glycogenolysis in primary cultures of mouse cerebral cortical astrocytes with an EC50 of 1.5 microM. A pharmacological analysis indicates an involvement of purinergic P2Y receptors in this action of ATP. Application of ...
The natural abundance 13C NMR intensity of the glycogen C1 resonance was measured in the surgically exposed liver of rabbits in vivo (n = 17) by integration from 98 to 104 ppm and compared double blindedly to the subsequent biochemical measurement. Coil lo ...
Two alpha-L-rhamnohydrolases with different substrate specificities were isolated from a commercial preparation produced by Aspergillus aculeatus. The first rhamnohydrolase was active toward p-nitrophenyl-alpha-L-rhamnopyranoside, naringin, and hesperidin ...
A new enzyme, rhamnogalacturonan (RG) alpha-D-galactopyranosyluronohydrolase (RG-galacturonohydrolase), able to release a galacturonic acid residue from the nonreducing end of RG chains but not from homogalacturonan, was purified from an Aspergillus aculea ...
VIP neurons are a homogeneous population of intracortical bipolar cells. They receive excitatory synapses from afferent circuits to the cortex and exert effects on neurons, astrocytes, and capillaries. Effects on the two latter cell types imply that VIP ne ...
BACKGROUND: Deep hypothermia has been associated with an increased incidence of postoperative neurologic dysfunction after cardiac surgery in children. Recent studies suggest an excitotoxic mechanism involving overstimulation of glutamate receptors. Extrac ...
