Raman spectroscopy is a non-destructive, non-invasive, rapid and economical technique which has the potential to be an excellent method for the diagnosis of cancer and understanding disease progression through retrospective studies of archived tissue samples. Historically, biobanks are generally comprised of formalin fixed paraffin preserved tissue and as a result these specimens are often used...

“Bodies of tow and paraffin” is the phrase used by Georges Braque, pioneer with Picasso Cubism, to describe alarm that he felt at his first sight Les Demoiselles d'Avignon when paid a visit as was painting it in Bateau Lavoir 1907. This sums up well reactions work produced among friends Spanish painter who saw it. chapter summarises these horror, disgust disappointment Picasso's acquaintances. ...

PURPOSE The aim of the study was to evaluate CD31 and CD105 immunohistochemical expressions in tissue microarrays from 360 breast carcinomas. STUDY DESIGN Computerized (ACIS/Chromavision) assisted image analysis was performed to compare immunoreactions in tissue microarrays with those in current paraffin and frozen sections. We also aimed to determine the CD105 and CD31 prognostic significanc...

The data focused on the value of immunofluorescence on paraffin-embedded sections are controversial, and it is still difficult to obtain reproducible results. The aim of our study was to evaluate the usefulness of immunofluorescence on paraffin-embedded renal section in detecting immune complex deposits in IgA nephropathy (n = 24), membranous glomerulopathy (n = 22) and lupus nephritis (n = 24)...

Paraffin wax was microencapsulated by suspension polymerization with a polymer shell of methylmetacrylate (MMA)-styrene (St) copolymer. The influence of the copolymer/paraffin mass ratio and the MMA/St mass ratio on the encapsulation process and the physical properties of the microcapsules obtained were studied. It was observed that paraffin is difficultly encapsulated when the ratio polymer/pa...

This study describes results of a household survey conducted in Eshane in the rural Kwazulu-Natal Midlands in April 2002, including baseline sociodemographic, energy usage, paraffin-related injury and safety knowledge information. A total of 404 interviews were conducted in five villages that fell within a 10-kilometre radius of the proposed Eshane integrated Energy Centre. Paraffin usage was h...

Programmed death 1 (PD-1) protein and its ligands, PD-L1 are two proteins that have been widely studied in many solid tumours. However, only limited observations were made lymphomas, which mainly Hodgkin lymphomas. We aimed to evaluate the expressions of PD-1 tumour microenvironment cells primary extranodal non-Hodgkin lymphoma (peNHL). A cross-sectional study using 87 archived formalin-fixed p...

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehydrogenation, hydrogenation...
