In this paper we present a simple and rapid method of modifying poly(dimethylsiloxane) (PDMS) surfaces with paraffin wax. PDMS that contains a layer of paraffin wax at its surface resists the absorption of hydrophobic molecules; we used fluorescence microscopy to confirm that paraffin-modified PDMS resists the absorption of rhodamine B. Furthermore, we demonstrated that microfluidic devices mad...

Background Constipation is one of the most common disorders in children. The purpose of this study was to compare paraffin and polyethylene glycol (PEG) in the treatment of children with chronic constipation. Materials and Methods This study is a double-blind randomized trial. Total 160 children aged 2-12 years old with chronic constipation attending the pediatric clinic of Mousavi Hospital in ...

The effect of temperature on fluorescence and emission anisotropy spectra of 4-cyano-N,Ndimethylaniline (CDMA) was investigated in viscous (glycerol and paraffin oil) and rigid (polyvinyl alcohol) PVA and polyvinyl chloride) PVC) media. A strong effect of temperature on the intensity of a and b emission bands was observed. It was also found that the emission anisotropy, r, does not vary in the ...

Background: Formalin-fixed paraffin-embedded (FFPE) specimen archives are a valuable source of sample material for molecular biological analysis. However, the DNA isolated from FFPE samples is usually low in concentration and fragmented. Thus, it necessary to optimize extraction protocol obtain best results. Proteinase K incubation undoubtedly crucial procedures, but this step often not well ex...

INTRODUCTION This article reviews the literature pertaining to bismuth iodoform paraffin paste. OVERVIEW Bismuth iodoform paraffin paste is used in most otolaryngology departments on a daily basis. Questions about its properties are common in postgraduate otolaryngology examinations. This article reviews bismuth iodoform paraffin paste's current and historical usage, constituents, properties,...
