There is an increasing interest by the flavor industry for producing natural aroma compds. through biocatalysts. L-Phenylalanine is transformed by Saccharomyces cerevisiae into 2-phenylethanol, which has a rose-like odor. Unfortunately this product inhibit ...

Supercapacitors are new components ale to store a high energy density aven if this energy is still lower than the energy batteries can store. This paper shows how supercapacitors can be used to supply electric vehicle such as busses and tramways. The "on-b ...
This study explores the potential of MALDI-TOF MS for the mass measurement of large non-covalent protein complexes. The following non-covalent complexes have been investigated: aerolysin from Aeromonas hydrophila (335 kDa) and α-haemolysin from Staphylococ ...
Using a paradigm by which rats forced to drink a weak ethanol solution (2.5% w/v) (conditioning session) develop ethanol preference in consecutive retention testing days, the effects of the administration of the kappa opioid antagonist MR-2266-BS, prior to ...
Attention has been focused on the possibility of an interaction between the endorphinergic system and ethanol intake. In the present study, the effects of subcutaneous (SC) administration of beta-endorphin (beta-E) (0.25, 1 and 5 micrograms/kg) and/or nalo ...
An on-resin Ugi four-component reaction followed by an intramol. nucleophilic arom. substitution (SNAr) has been developed for the rapid access to biaryl-ether contg. macrocycles. Supported isocyanide was prepd. and used together with heptanal, butylamine, ...
Combining mathematical programming and thermodynamic analysis for solving energy integration of industrial processes appears to be a very powerful tool to target minimum energy cost requirements. Defining the role played by thermodynamic analysis and numer ...
The effects of subcutaneous (SC) administration of D-Ala2-Met5-enkephalinamide (DAME) (1, 10 and 100 micrograms/kg), synthetic analog of Met-enkephalin, on the acquisition of ethanol preference were studied in male Wistar rats. Under our procedural conditi ...
