Aims-We have previously demonstrated the abnormal localisation of expression of the CD44 gene in carcinoma cells in cryostat sections of fresh frozen tumour tissues, using radioactive in situ hybridisation (RISH). In order to facilitate further analysis of the expression of this gene in a wider range of neoplastic and non-neoplastic conditions, we have developed a technique which can visualise ...

Fifty-four extracted primary maxillary central incisors with some incisal edge intact as a reference point and no more than 25% of root resorption, signs of canal obstructions, or root anomalies were included. 3 The sample was equally and randomly distributed to pressure syringe, lentulo spiral, or incremental groups. Immediately following extraction, each tooth was placed in 10% formalin then ...

Abstract Among the flow assurance problems that petroleum industry faces, deposition of paraffin waxes on to wall pipeline is most challenging. The challenge arises when crude oil temperature decreases below wax appearance which prompts crystallization in oil. An efficient method remedying utilization chemical inhibitors. However, currently used inhibitors are costly and environmentally harmful...

Microencapsulated paraffin wax/polyaniline was prepared using a simple in situ polymerization technique, and its performance characteristics were investigated. Weight losses of samples were determined by Thermal Gravimetry Analysis (TGA). The microencapsulated samples with 23% and 49% paraffin showed less decomposition after 330 °C than with higher percentage of paraffin. These samples were the...

TiO2 nanoparticles about 20 nm in diameter in the form of anatase were prepared and characterized. The nanoparticles were successfully dispersed into a paraffin wax (PW) matrix without any surfactant. The differential scanning calorimetric instrument and the transient short hot-wire method were used to measure the thermal properties of the TiO2/PW composites. It is found that the phase-change t...

Wax D prepared from the P-6 strain of the scotochromogenic species of Mycobacterium scrofulaceum constituted 0.3% of the dry bacilli. In the acid hydrolysates, alanine, glutamic acid, glycine, and mesodiaminopimelic acid were found as amino acid constituents. Mannose, galactose, and glucosamine were detected by paper chromatography. However, arabinose could not be detected. The quantity of hexo...

Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates. To test this hypothesis, leaf appearance in spring wheat ('Nordic') ...

potassium chloride (kcl) is a highly water soluble substance which is usually used to prevent hypokalemia. oil in water disperse phase encapsulation method was used to prepare kcl loaded microcapsules using beeswax and carnauba wax as a hydrophobic matrix. the morphology and characteristics of kcl loaded microspheres were studied using scanning electron microscopy (sem), photon correlation spec...

The purpose of this study was to develop a pharmaceutical formulation containing fatty acid extract rich in free omega-3 fatty acids such as eicosapentaenoic acid and docosahexaenoic acid for topical use. Although the health benefits of cod liver oil and other fish oils taken orally as a dietary supplement have been acknowledged and exploited, it is clear that their use can be extended further ...
