For rapid chilling fresh products we propose the immersion in melting carbon dioxide hydrate crystals, produced at +8 oC and 30 bar. We compare the chilling time of a specific fresh product from 30 to 4 oC making use of a “shock freezer” (2 m/s air velocity, air at -10 oC) and applying a slurry of CO2 hydrate crystals. Furthermore the effect of these two methods on the weight loss of the produc...

An important question for ecologically valid virtual environments is whether cohort characteristics affect immersion. If a method for assessing a certain neurocognitive capacity (e.g. attentional processing) is adapted to a cohort other than the one that was used for the initial normative distribution, data obtained in the new cohort may not be reflective of the neurocognitive capacity in quest...

The present study investigates the antinociceptive effect of the pyrazolyl-thiazole derivative 2-(5-trichloromethyl-5-hydroxy-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-bromophenyl)-5-methylthiazole (B50) in mice. Male albino Swiss mice (30-40 g) were used in the acetic acid-induced abdominal writhes and tail-immersion tests. B50 caused dose-dependent antinociception (8, 23 and 80 micromol/kg, ...

BACKGROUND Celosia cristata Linn. (Amaranthaceae) is used in traditional medicine for the treatment of headache, sores, ulcers, eye inflammations, skin eruption, painful menstruation and carpal tunnel syndrome. This study was performed to evaluate the antinociceptive activity of methanol extract of the whole plant of C. cristata (MECC). METHODS The evaluation of the antinociceptive effect of ...

The periaqueductal grey (PAG) area is involved in pain modulation as well as in opiate-induced anti-nociceptive effects. The PAG possess dopamine neurons, and it is likely that this dopaminergic network participates in anti-nociception. The objective was to further study the morphology of the PAG dopaminergic network, along with its role in nociception and opiate-induced analgesia in rats, foll...

OBJECTIVE The main objectives of this study were to qualitatively evaluate the profile of phytochemical constituents present in methanolic extract of Microcos paniculata bark (BME) and fruit (FME), as well as to evaluate their anti-inflammatory, analgesic and antipyretic activities. METHODS Phytochemical constituents of BME and FME were determined by different qualitative tests such as Molisc...

An aqueous extracts of stem and leaves of Boerhaavia Diffusa (Aq.EBD) and leaves of Anisochilus Carnosus (Aq.EAC) was studied for hepatoprotective, analgesic and antipyretic activity. Hepatotoxicity was introduced in Albino rats of either sex by intraperitoneal injection of CCl4 (in olive oil). Tail immersion method and Hot plate method in mice were studied for analgesic activity, Yeast induced...
