neutral bidentate n-o type complexe of vo(ii) has been synthesized through condensation of dpenicillamine,(d-h2pen), with bis(acetylacetonate)- oxovanadium(iv),[vo(acac)2], at neutralmedium . the established schiff base(no type) complex was characterized on the basis of ir andmass spectroscopy techniques.besides,d-h2pen binding behavior to[vo(acac)2] has been studiedin thermodynamic viewpoint u...

objective: evaluating the effect of dentin conditioning with edta on microleakage of composite resin restorations, using two etch and rinse and two self-etch adhesives. materials and methods: one hundred and sixty extracted molars received class v cavity preparations right under the cej and were randomly divided into eight groups of 20, usingfour different adhesive systems. these adhesives incl...

Organoboranes carrying electron-withdrawing substituents are commonly used as Lewis acidic catalysts or cocatalysts in a variety of organic processes. These Lewis acids also became popular through their application in `frustrated Lewis pairs', i.e. combinations of Lewis acids and bases that are unable to fully neutralize each other due to steric or electronic effects. We have determined the cry...

INTRODUCTION To investigate the effects of bisphosphonates (Bis) (etidronate, alendronate, and risedronate), alone and in combination with statin, on the BMD (bone mineral density) and bone metabolism of rheumatoid arthritis (RA) patients. METHODS Seventy-seven RA patients who had been receiving prednisolone (PSL) and Bis for over 4 years were divided into two groups: Bis and Bis + statin (n ...

To the best of our knowledge, the palliative care unit at Port Kembla Hospital in Warrawong, New South Wales, Australia, is the only one currently evaluating the contribution that Bispectral Index (BIS)-like technology makes to the management of unconscious palliative care patients. We are trialing the BIS monitor with forty eligible subjects who, with their immediate family members, give us in...

Bisphenol A-glycidyl methacrylate (Bis-GMA) and urethane dimethacrylate (UDMA) are widely used as the primary components of (meth)acrylic monomers. However, use Bis-GMA, which is a bisphenol A derivative, in dentistry being questioned after was found to exhibit estrogenic activity. Although UDMA considered substitute for bis-GMA, mechanical properties cured resin composites containing less than...

provided the original work is properly cited. CC In October 1996, the bispectral index monitor (BIS) was introduced to anesthesiologists as a reliable brain function monitor that allowed anesthetic titration over the complete range of cortical activity [1]. In January 2004, the BIS received Food and Drug Administration (FDA) approval for reducing the incidence of intraoperative awareness during...

some new symmetrical tetraaza schiff base ligands containing 2-quinolinecarboxaldehyde moiety formed from condensation reaction of 2-quinolinecarboxaldehyde and o-phenylenediamine derivatives, such as n, nˊ-bis(2-quinolylmethylidene)-4-methoxy-1, 2-phenylenediimine (l1), n, nˊ-bis(2-quinolylmethylidene)-4-methy-1, 2-phenylenediimine (l2), n, nˊ-bis(2-quinolylmethylidene)-4-chloro-1, 2-phenylene...
