The analysis of E-2-nonenal is of considerable interest for the brewery industry as this compound is claimed to be responsible for a paper/cardboard unpleasant flavour. Usually, the presence of E-2-nonenal can be noticed in aged beers at levels higher than 0.1 microg/l. In this work, an analytical method was developed to determine E-2-nonenal in beer(More)
The aim of this study was to evaluate the effect of green tea as a protective measure on eroded dentin. Disks of human coronary dentin were selected based on surface hardness and randomly assigned to 3 groups (n = 10): DW - distilled water, CHX - 0.2% chlorhexidine digluconate, and GT - green tea. The disks were allowed to acquire pellicle for 2 hours and(More)
BACKGROUND To analyse the infectious diseases of inpatient diabetics in a general hospital. MATERIAL AND METHODS We selected retrospectively 233 records of diabetics admitted during September, October and November 1990. There were 38 (16.3%) patients with infection, age 58.9 +/- 15.3 years, 29 (76.3%) were female, duration of diabetes were 10.8 +/- 9.1(More)
A method for the simultaneous determination of E-2-nonenal and beta-damascenone in beer by reversed-phase liquid chromatography using UV detection is presented. The method consists of beer steam distillation, followed by an extraction/concentration step using Sep-Pak Plus C18 RP cartridges and determination by HPLC at 226 nm UV-absorption maximum. The(More)
OBJECTIVE To evaluate the capacity of methotrexate (MTX) to control mild activity of systemic lupus erythematosus (SLE), and to evaluate the capacity of MTX to reduce steroid requirement, as well as to evaluate the side effects of MTX in patients with SLE. METHODS A prospective, randomized, controlled, double blind trial. Forty-one patients with SLE began(More)
