Nowadays, non-alcoholic (NAB) and low-alcoholic beers (LAB) still significantly suffer from staling defects when fresh, partially due to absence of ethanol as antioxidant. In the current work, fate flavan-3-ols (monomers, dimers, trimers) bitter compounds (isohumulones, humulinones, etc.) 11 commercial NABLABs available on Belgian market was monitored through one year aging at 20 °C in dark. Fr...

In this present work the fresh flowers of Allamanda Cathartica Linn. were collected and the solution of Allamanda Cathartica was extracted with 90% methanol under reflux. The alcoholic extract was concentrated in vacuo and the aqueous concentrate, successively fractionated with benzene, peroxide free diethylether and ethylacetate. The benzene fraction was not yielding any isolable material. The...

Management of airway in trauma victim with penetrating cervical/thoracic spine injury has always been a challenge to the anaesthesiologist. Stabilisation of spine during airway manipulation, to prevent any further neural damage, is of obvious concern to the anaesthesiologist. Most anaesthesiologists are not exposed to direct laryngoscopy and intubation in lateral position during their training ...

Microwave assisted new aldol condensation reaction of 1-oxo-1,2,3,4tetrahydrocarbazoles 1 with thiophene-2-carbaldehyde 2 in the presence of alcoholic KOH affords a single product 2-Thiophen-2-ylmethylene-2,3,4,9-tetrahydro-carbazol-1-one 3. 3 on irradiation with hydroxylamine hydrochloride yielded 3-Thiophen-2-yl-4,5-dihydro-10H-2-oxa-1,10-diazacyclopenta[a]carbazole 4 and 3 on irradiation wit...

The glycoside fraction of fresh rhizomes from Magydaris pastinacea (Lam.) Paol. was separated from the alcoholic extract using the method of Kobayashi et al. The fraction was found to have six main constituents, the most abundant of which had previously been isolated and identified as 7-O-beta-D-glucopyranosyl-8-(2',3'-dihydroxy-3-methyl-butylcoumarin++ +). The present paper describes the separ...

A novel, efficient, time-saving and reliable radiolabeling procedure via nucleophilic substitution with [(18)F]fluoride is described. Different radiolabeled aliphatic and aromatic compounds were prepared in high radiochemical yields simply by heating of quaternary anilinium, diaryliodonium and triarylsulfonium [(18)F]fluorides in suitable solvents. The latter were obtained via direct elution of...

The crude extracts of fruits of Sapindus mukorossi, leaves of Cestrum nocturnm, Cestrum diurnum, and Asclepias curassavica were tested under laboratory conditions against Aedes aegypti, a vector of dengue and chikungunya, for their larvicidal properties. Bioassay experiments carried out with crude alcoholic extracts of Sapindus mukorossi, Cestrum nocturnm, Cestrum diurnum, Asclepias curassavica...

Background and objectives: Leishmaniasis is caused by the genus Leishmania. Medications such as antimony compounds for the treatment of the disease are associated with limitations along with several side effects and disease recurrence; thus, evaluation of natural compounds with history of antimicrobial properties such as   Pleurotus ostreatus, is of a great im...

Serum and tissue hepatitis B virus (HBV) markers were compared in 35 alcoholic and 23 non-alcoholic subjects affected by chronic liver disease. Seventeen point one per cent of alcoholic and 21.7% of non-alcoholic subjects had HBV tissue markers, but not serum markers, for this virus. It is therefore concluded that showing the presence of HBV tissue markers permits a better aetiological definiti...

In this study, the effect of water and alcoholic (ethanol) extracts Caper Bush Capparis spinosa L., Cumine Cuminum cyminum L. , Black pepper Piper nigrum Sage Salvia sp. Cat thyme Teucrium polium plants on 4th instar larvae Culex quinquefasciatus have been evaluated .The results showed that extract P. had highest larvae, with 48h LC50 155. 9 ppm followed by ethanol C. 308.2 ,315.1and 791.4 resp...
