cotton fibres were subjected to cleaning process and then characterized for maturity. decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and trichloroethene on the native fibres were carried out. the effects of these on the strength and moisture regain were investigated. the activation energies of the dyeings were also analysed with durazol scarlet red 4 bas. the r...

A novel microorganism, designated as LG12, was isolated from soil based on its ability to use acrylic acid as the sole carbon source. An electron microscopic analysis of its morphological characteristics and phylogenetic classification by 16S rRNA homology showed that the LG12 strain belongs to Rhodococcus erythropolis. R. erythropolis LG12 was able to metabolize a high concentration of acrylic...

BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...

PURPOSE To compare the clinical results of heparin surface modified (HSM) hydrophilic acrylic intraocular lens (IOL) with those of hydrophobic acrylic IOL. METHODS One hundred patients with cataract were randomized to receive one of acrylic foldable IOLs after phacoemulsification: HSM hydrophilic acrylic IOL (n=50) BioVue3 (BioVue, OII, Ontario, CA, USA) and hydrophobic acrylic IOL (n=50) Sen...

Responsive functional composite fibre mats that are mechanically stable and impervious to water exposure produced by coaxial electrospinning of thermotropic liquid crystal (LC) core inside a water-based solution poly(vinyl alcohol) (PVA) poly(acrylic acid) (PAA) forming the sheath. Because LCs usually cannot be spun solutions due excessive interfacial tension ?, n enabling step is addition etha...

Larger cranial bone defects can cause cranial disfigurement as well as potential mechanical brain trauma. Conventionally pre-fabricated acrylic cranioplasty implants require complicated procedures and result in potential dimensional and contour inaccuracies. The development of stereolithographic techniques for generating acrylic resin skull models allows the pre-fabrication of custom acrylic re...

BACKGROUND Chairside softliners are used more frequently than is reported and studies regarding the bond strength of chairside softliners to heat-polymerized denture base resin are few and limited. Hence, this study was conducted to comparatively evaluate the shear bond strength of two chairside soft relining materials viz., autopolymerizing plasticized acrylic resin liner and a silicone-based ...

PURPOSE This meta-analysis aims to evaluate the differences in performance of posterior capsular opacification (PCO) between hydrophobic acrylic intraocular lens (IOLs) and hydrophilic acrylic IOLs. SETTING Tianjin Medical University, Tianjin Eye Hospital, Tianjin Key Laboratory of Ophthalmology and Visual Science, Tianjin, China. DESIGN Systematic review of randomized controlled trials (RC...

statement of problem: acrylic teeth of dentures are prone to discoloration due to frequent exposure to different colouring solutions in the oral environment. thus, in order to maintain their aesthetic appearance, they must possess high colour stability while exposed to colorant solutions. objectives: to compare the colour stability of three different brands of acrylic teeth following immersion ...
