Abstract:

BACKGROUND: Epidural steroid injections are widely used to treat spinal and radiating pain. However, crystal formation has recently been reported in mixtures of ropivacaine and nonparticulate steroids, commonly used in epidural steroid injections. OBJECTIVES: Our study assessed the physicochemical stability of mixtures of different nonparticulate steroids and ropivacaine and aimed to propose a safe regimen for epidural steroid injections. STUDY DESIGN: An in vitro protocol was used to examine the physicochemical stability of epidural steroid injection mixtures most commonly used at our institu

Abstract:

Nature is highly efficient at producing chiral compounds that are enantiomerically pure. The inherent chirality of naturally occurring biomolecules means that many have the potential to be used as chiral dopants for cholesteric liquid crystal (CLC) systems. Though many biomolecules have been identified as chiral dopants, many remain yet to be probed for their ability to function as chiral dopants. Here, 10 naturally occurring biomolecules comprised of steroids and bile acids were tested as chiral dopants for CLCs. Progesterone was identified as having high miscibility with nematic liquid cryst

Background:Chronic tophaceous gout is usually difficult to treat with urate lowering therapy (ULT) [1]. Faster resolution of tophi has been seen with use of pegloticase [2], but this drug is costly and not widely available. Local steroid use is recommended in acute gouty arthritis but its role in reduction of tophi has not been studied. This study was aimed to see the effect of local steroids in tophi resolution.Objectives:To study the change in size of gouty tophi with local steroid injection compared to conventional treatment.Methods:Four crystal proven chronic tophaceous gout patients with

Abstract:

Three crystal forms of the steroid 20-hydroxyecdysone were identified by single-crystal X-ray diffraction analysis: a solvent-free modification, a methanol solvate hydrate and a trihydrate. The structure of a closely related steroid, polypodine B (the 5,20-dihydroxy derivative of ecdysone), was determined in its monohydrate form. Since the unit-cell volume of unsolvated 20-hydroxyecdysone was found to be considerably smaller than that of ecdysone [Huber & Hoppe (1965). Chem. Ber. 98, 2403–2424], a new structure determination of ecdysone was performed, which confirmed the unexpected differe

Introduction: Allergic fungal rhinosinusitis (AFRS), a subset of sinusitis secondary to hypersensitivity, is clinically similar to chronic rhinosinusitis with nasal polyp but histologically different with rich eosinophils and Charcot Leyden crystals. Since the primary pathology in AFRS is immune mediated, the recurrence rates are high. In this study, we describe the application of radical extended sinus surgery (RESS) as the surgical technique with the usage of postoperative high-volume steroidal nasal irrigation and short-term oral steroid therapy – a threefold strategy – for the prevention o

Acute gout is a common inflammatory arthritis in the adult population. Epidemiological evidence suggests that the prevalence of gout is steadily on the rise due to longevity, coexisting comorbidities, and iatrogenic causes contributing to hyperuricaemia. Acute gout usually presents as a self-limiting flare of synovitis that occurs due to deposition of monosodium urate crystals. The frequency of flares generally increases over time in patients who continue to have hyperuricaemia and their risk factors for acute gout attacks have not been adequately addressed.

Treatment of flares can be achieved with non-steroidal anti-inflammatory drugs, colchicine, or corticosteroids (systemic or intra-articular).

For example, when considering reaction mechanisms it is difficult to determine the extent of steric hindrance or the accessibility of functional groups if one does not have a three-dimensional view of the system. The electron microscope can, as was shown, for example, by Labaw and Wyckoff (1958), be used to view macromolecules such as those of viruses.

Abstract:

Abstract The stress corrosion cracking (SCC) susceptibility of zirconium (UNS R60702) and one of its alloys, Zircaloy-4 (UNS R60804), was studied in 10 g/L iodine dissolved in various alcohols: methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol and 1-octanol. SCC was observed in all the systems studied and the crack propagation rate was found to vary depending on the size of the solvent molecule. As the solvent molecular weight increased, the crack propagation rate decreased. Preceding crack propagation, intergranular attack was found in all the solutions tested. The intergranular corrosion

Abstract:

This paper presents the results of a study performed to examine the effectiveness of several different formulations of thermochromic liquid crystal (TLC) material for use in a light transmission based temperature measurement system. We report on experiments performed on six different types of TLC material. We used a spectrophotometer to measure the percent of light transmitted through a layer of each TLC material for wavelengths from 400 to 700 nm as a function of temperature. We also applied TLC material directly onto electroluminescent lights and used a CCD camera to look at the intensity of

Abstract:

The design and construction of artificial supramolecular architectures on surfaces is of great current interest and represents an important aspect of molecular self-assembly, because self-assembly offers highly ordered mesoscale structures with desired chemical functionalities and physical properties. The fabrication of polar molecular superstructures proves particularly challenging since polar molecular materials are essential to second-order nonlinear optical (NLO) technologies. Several approaches such as the Langmuir-Blodgett technique and liquid crystals have been reported to generate mole

Abstract:

Self-assembled monolayers (SAMs) have received considerable recent attention as molecular-level lubricants in, for example, micro-electro-mechanical systems (MEMS).[1] Of particular interest as tribological films have been SAMs terminated by fluorocarbon groups, because of their inert nature and enhanced thermal stability. Surprisingly however, fluorocarbon films were shown to actually produce higher coefficients of friction (relative to CH3-terminated films) in atomic force microscopy (AFM) studies. Subsequent work has concluded that the increased van der Waals radius of the fluorine groups (
