AIMS To investigate the status of chromosome 17 in a series of medulloblastomas using comparative genomic hybridisation (CGH) and fluorescence in situ hybridisation (FISH). METHODS Frozen tissue and formalin fixed, paraffin was embedded tissue from 27 medulloblastomas were analysed by CGH and FISH, respectively. CGH ratio profiles for chromosome 17 were compared with the results of FISH, for ...

Dental waxes are often a blend of several waxes that are necessary to develop the most desirable qualities. In general, more information is available on physical properties and manipulation of dental waxes than on the composition or nature of the ingredients. Since heats of transition are fundamental in characterizing the chemical nature of matter, this information was obtained from waxes and b...

In the oil industry, the issue of controlling paraffin deposits remains relevant today. The most common way in the Perm Krai to remove paraffin is to lower the scrapers into the well.  This method is the main in the fight against paraffin deposits, but does not provide absolute protection. The least costly way to control paraffin is to use flushing with hot oil or water, but it does not always ...

The present experimental study reports the thermal performance analysis of a phase change material (PCM)-basedfinned heat sink placed on silicone rubber heater which mimics CPU chip and is cooled by natural forced convection. subjected to constant cyclic loading for five input power values (4, 6, 8, 10, 12 W). Paraffin wax 1-hexadecanol are selected as PCM this study, have melting points in ran...

To investigate the role of chewing and taste in the meal-induced rapid increase in splanchnic blood flow, we compared the blood flow responses in the celiac artery (CA) and superior mesenteric artery (SMA) to chewing solid food with a chocolate taste (FOOD) and paraffin wax without taste (WAX). After 5 min of baseline measurement, 15 healthy subjects repeated chewing and expectorating the FOOD ...

In order to study the effects of pore structure and size porous carrier material on phase transformation behavior composite change materials (CPCMs), sizes three different expanded graphites (EGs) (50, 80, 100 mesh) were studied using N2 adsorption-desorption isotherms scanning electron microscopy. Then, thermal characterization CPCMs prepared with paraffin wax EGs tested differential calorimet...

Benchmarks Fixed tissues often need to be arranged in a particular configuration , order, or orientation prior to processing for paraffin embedding. Although it is possible to arrange tissues after infiltration (during the final stages of paraffin embedding), it can be more convenient and practical to do this at the time of dissection or tissue collection. Agar has been the classical medium use...
