BACKGROUND Currently available drugs for the treatment of ulcerative colitis (UC) include salicylates, thiopurines, corticosteroids and new anti-tumour necrosis factor (TNF)-α biologics. Among these medications, corticosteroids in children and adolescents may adversely affect the patients' growth and development. Further, UC patients have elevated and activated myeloid lineage leucocytes includ...
To reduce volumetric shrinkage of the commercially available polymeric dental composite during curing reaction, (2,2-bis [4-(2-hydroxy-3-methacryloyloxy propoxy) phenyl] propane) (bis-GMA) derivatives, i.e., (2,2-bis[3-methyl, 4-(2-hydroxy-3-methacryloyloxy propoxy) phenyl] propan) (DMBis-GMA) and (2,2bis[3,5-dimethyl, 4-(2-hydroxy-3-methacryloyloxy propoxy) phenyl] propane) (TMBis-GMA) were sy...
2, 2-Bis [4- (2-hydroxy-3-methacryloyloxypropoxy) phenyl] propane (bis-GMA) is widely used in dentistry as a monomer of composite resin system and their bonding agents. Since bis-GMA is not purified, its isomers and some chemicals such as residual initiator remain in the commercial product. Bis-GMA and iso-bis-GMA were separated from bis-GMA monomer by HPLC. NMR spectra of both monomers were re...
Factorial designs are arguably the most widely used designs in scientific investigations. Generalized minimum aberration (GMA) and uniformity are two important criteria for evaluating both regular and non-regular designs. The generation of GMA designs is a non-trivial problem due to the sequential optimization nature of the criterion. Based on an analytical expression between the generalized wo...
BACKGROUND AND AIMS Subcutaneous aseptic abscess is one phenotype of neutrophilic dermatitis. We were interested to see if a case of steroid refractory Crohn's disease (CD) complicated by subcutaneous aseptic neutrophilic abscesses responds to intensive granulocyte/monocyte adsorptive apheresis (GMA). METHODS The patient was a 21-year-old male with worsening severe CD while on oral prednisolo...
R-GMA is a realization of the Grid Monitoring Architecture (GMA) that also exploits the power of the relational data model and the SQL query language. The biggest challenge during the development of R-GMA was to ensure that it could be scaled to operate in a large grid reliably. The system is being used in areas as diverse as resource discovery, job logging and bookkeeping, network monitoring a...
The psychological construct of general mental ability (GMA), introduced by C. Spearman (1904) nearly 100 years ago, has enjoyed a resurgence of interest and attention in recent decades. This article presents the research evidence that GMA predicts both occupational level attained and performance within one's chosen occupation and does so better than any other ability, trait, or disposition and ...
UNLABELLED Psychosocial work characteristics including high demands, lack of control and poor social support have consistently been linked to poor health as has poor general mental ability (GMA). However, less is known about the relationships between stable individual factors such as GMA, psychosocial work characteristics and health. OBJECTIVE The present study investigated how childhood ment...
OBJECTIVES To evaluate the effect of additives on the water sorption characteristics of Bis-GMA based copolymers and composites containing TEGDMA, CH3Bis-GMA or CF3Bis-GMA. MATERIAL AND METHODS Fifteen experimental copolymers and corresponding composites were prepared combining Bis-GMA and TEGDMA, CH3Bis-GMA or CF3Bis-GMA, with aldehyde or diketone (24 and 32 mol%) totaling 30 groups. For com...
We demonstrate a new light-responsive poly(N-isopropylacrylamide) (PNIPAAm) hydrogel nanocomposite incorporating glycidyl methacrylate functionalized graphene oxide (GO–GMA) instead of metallic nanoparticle fillers. GO–GMA is synthesized by esterification with glycidyl methacrylate. GO–GMA incorporated hydrogels are synthesized by photopolymerization of NIPAAm including 4-dimethylaminopyridine ...
