OBJECTIVE Evaluation of gait performance and muscle activity patterns as well as clinical efficacy and safety after single intraarticular injection with hyaluronan compared with triamcinolone in patients with knee osteoarthritis. MATERIALS AND METHODS This trial evaluated the influence of a single injection of hyaluronan or triamcinolone on gait pattern and muscle activity. For clinical evalu...

Dear Editor: Miyamoto et al show that intravitreal triamcinolone reduces macular edema as early as 1 hour after injection. They suggest that the time pattern demands that nongenomic mechanisms must be involved in the therapeutic effect of triamcinolone on retinal edema. Vasogenic edema in all tissues, including the retina, may be understood in terms of Starling’s law, by which the balance of hy...

Epidural corticosteroid injection is a commonly used approach for managing back pain of several etiologies. The risk of clinical complications from systemic absorption is felt to be rare. Ritonavir is a protease inhibitor whose potent cytochrome P450 3A4 inhibition is exploited for pharmacologic boosting in human immunodeficiency virus (HIV) infection. It has been associated with systemic hyper...

AIMS To demonstrate the potential use of in vitro poly(lactic-co-glycolic acid) (PLGA) microparticles in comparison with triamcinolone suspension to aid visualisation of vitreous during anterior and posterior vitrectomy. METHODS PLGA microparticles (diameter 10-60 microm) were fabricated using single and/or double emulsion technique(s) and used untreated or following the surface adsorption of a...

BACKGROUND Tendinopathies are often empirically treated with oral/topical nonsteroidal anti-inflammatory medications and corticosteroid injections despite their unclear effects on tendon regeneration. Recent studies indicate that tendon progenitors exhibit stem cell-like properties, i.e., differentiation to osteoblasts, adipocytes, and chondrocytes, in addition to tenocytes. Our present study a...

BACKGROUND To quantitatively compare short-term hard exudates (HEs) alteration in patients with diabetic macular edema (DME) after intravitreal triamcinolone, dexamethasone implant or bevacizumab injections. METHODS This retrospective study enrolled DME eyes with HEs that underwent a single-dose intravitreal injection of triamcinolone (25 eyes), dexamethasone implant (20 eyes), or three month...

An optical basicity scale of various ionic liquids (IL) anions has been determined by UV-Vis absorption spectroscopy. The indicator complex [Ni(tmen)(acac)][B(Ph)(4)] (tmen = tetramethylethylendiamine, acac = acetylacetonate) shows to be a sensitive probe as the position of the (3)A(2g)(F) --> (3)T(1g)(F) absorption maximum of square planar to octahedral Ni(2+) shifts distinctly depending on th...

The title compound, [Zn(C(8)H(10)F(3)O(2))(2)(CH(4)O)(2)], is a dimethanol coordinated zinc complex with the acetyl acetonate derivative 1,1,1-trifluoro-5,5-dimethyl-hexane-2,4-dionate. The bis--β-diketonate complex, which is isostructural with its Co analogue, is located on a crystallographic inversion center. The complex is octa-hedral with basically no distortion, and the methanol mol-ecules...

White organic light emitting devices were fabricated using phosphorescent materials. The device structure was ITO/ NPB (20 nm/ DPVBi(x nm)/CDBP:5% Ir(btp)2acac(35 nm)/Alq3(y nm)/BCP(5 nm)/CsF(1 nm)/Al (150 nm), where NPB is a N,N'-bis-(1naphthyl)-N,N'–biphenyl-1,1'-biphenyl-4,4'-diamine as a hole transporting layer, DPVBi is 4,4 '-bis(2,2 -diphenylvinyl)-1,1 '-biphenyl as blue fluorescent dye, ...
