Effects of alumina and zirconium dioxide particles on arachidonic acid metabolism and proinflammatory interleukin production in osteoarthritis and rheumatoid synovial cells. (1/3)We describe a model which can be used for in vitro biocompatibility assays of biomaterials. We studied the in vitro response of human osteoarthritis or rheumatoid arthritis fibroblast-like synoviocytes to Al2O3 or ZrO2 particles by analysing the production of interleukin-1 (IL-1) and interleukin-6 (IL-6) and the metabolism of arachidonic acid via lipoxygenase and cyclo-oxygenase pathways. Our results show that, in these cells and under our experimental conditions, Al2O3 and ZrO2 did not significantly modify the synthesis of IL-1 and IL-6 or the metabolism of arachidonic acid. (+info)

An expandable member is located on each of the branch catheters. The balloons are held together to provide a low profile as the device is advanced over the tracking guide wire. Upon reaching the bifurcated vessel, the balloons separated and are advanced over separate guide wires into separate branches of the bifurcated vessel. The bifurcated catheter assembly can be used to dilate a stenoses or deliver and implant a Y-shaped stent in the bifurcation.
We have found several unique keys that lead us to a successful Amalgam Removal and Replacement.. Before the patient comes in for the removal we have them take a special blood test to do a blood serum biocompatible dental material testing which shows the different types of dental materials their unique body composition is compatible with. Also, we can and have used other modalities for determining the proper match up of dental materials to the patient.. Most materials in the mouth have a current that is either positive (+) or negative (-) but the natural tooth does not have a charge. The unique principal we have incorporated into our program is that the currents do not come out when they [the amalgams] are removed. The standard for normal removals is to remove one quadrant (upper right, upper left, lower right, or lower left) at a time. The problem with this is the currents will reattach to the existing metals in the mouth which can create a meridian overload and an electrical short circuiting. ...

Patent US5335651 - Ventilator and care cart each capable of nesting within and docking with a ... - Google Patents
A hospital bed supported on a wheeled base, and a ventilator supported on a wheeled cart and docked to the base of the bed, the combination of ventilator and bed capable of being rolled as a single unit. The ventilator cart includes a wheeled base, and supports connected to the base for supporting a ventilator, with the supports providing for selective raising and lowering of the ventilator. The hospital bed base is wheeled and has a generally Y-shaped base frame. The outspread arms of the Y-shaped base frame receive the ventilator cart so that the two may be docked together. The ventilator when docked to the hospital bed base falls within the footprint of the bed as projected downwardly onto the floor. A latch secures the ventilator to the bed base. A disabling switch disables the high/low function of the bed preventing the bed from being lowered downwardly onto the ventilator. A power supply mounted to the bed base provides for uninterrupted operation of the ventilator. A care cart docks to the foot
Microfluidics provides an ideal tool to manipulate small volumes of liquids precisely, typically from the nanoliter to the microliter. Numerous microfluidic platforms have been developed to apply gradients controlled in space and time to cultured cells (Keenan and Folch, 2008; Kim and Wu, 2012), but here we will restrict our discussion to the applications of microfluidic devices in the context of axon guidance. One of the first devices developed and applied for neuronal guidance is composed of free and forced-choice regions (Wittig et al., 2005). The device consists of a Y-shaped microchannel. The forced-choice point is localized at the split in the Y-shaped microchannel. Neuronal cultures are placed in the presentation region, where they encounter a broad range of concentrations before eventually going into the forced-choice region. Gradient slope and shape are quantified and depend on the flow rate in the microchannels. This assay has been used to confirm that neonatal spiral ganglion neurons ...

Engineering reversible elasticity in ductile and brittle thin films supported by a plastic foil - Infoscience
Reversible deformation is a unique property of elastic materials. Here, we design and fabricate highly stretchable multilayered films by patterning Y-shaped motifs through films of non- elastic materials, e.g. plastics, metals, ceramics. By adjusting the geometry and density of the motif, as well as the thickness of the film(s), the effective spring constant of the engineered film(s) can be tuned. Three-dimensional bending of the patterned film(s) enables macroscopic stretchability and minimizes local film strain fields. The engineered films demonstrate no preferential direction of stretching and the proposed design is versatile. Furthermore our approach is compatible with thin-film processing. We demonstrate the Y-shaped motifs allow for the design of stretchable plastic foils coated with metallic and metal oxide conductors. We anticipate the patterned motifs can be scaled down to offer a wider range of elastic electronic materials to use in stretchable electronics and to create soft bioelectronics. (c

Implanted rats were trained to collect sucrose solution rewards by approaching and nose poking into a fluid well underneath an illuminated cue light in a fully automated, Y-shaped maze consisting of three identical chambers surrounding an equilateral center platform (Ito et al., 2008; Lansink et al., 2012). Each chamber contained three combinations of a cue light and a fluid well, one on each wall (see Fig. 1A). Nose pokes into the fluid wells were registered by interruption of infrared beams, which could trigger a solenoid valve system to deliver sucrose solution (15%) into the fluid well. The rats movement activity was tracked by 3 infrared beams per chamber, one of which was located at the chambers entrance.. Naive rats learned to associate a discrete cue (i.e., the illumination of a cue light) and reward availability in daily sessions of 135 trials that each started with cue light presentation. In each 9 trial block, cue lights were presented once in random order. Nose poke responses (,500 ...

The Great Dyke is a linear geological feature that trends nearly north-south through the centre of Zimbabwe passing just to the west of the capital, Harare. It consists of a band of short, narrow ridges and hills spanning for approximately 550 kilometres (340 mi). The hills become taller as the range goes north, and reach up to 460 metres (1,510 ft) above the Mvurwi Range. The range is host to vast ore deposits, including gold, silver, chromium, platinum, nickel and asbestos. Geologically the Great Dyke is not a dyke, but is lopolithic and Y-shaped in cross-section. It is a group of layered ultramafic intrusions that extend across Zimbabwe with a strike of about N20°E. The width of the intrusions vary from 3 to 12 km (7.5 mi). The Great Dyke is unusual in that most ultramafic layered intrusions display near horizontal sill or sheet forms. The well-layered lower units of ultramafic rocks comprising the Great Dyke are locally overlain by erosional remnants of gabbroic rock. These mark the centres ...
Antibody drug development has traditionally focused on engineering the tops of the "arms" of the Y-shaped antibody - a component known as the Fv domain because this region is responsible for binding to a specific target. This approach has created wildly successful drugs, yet many targets cannot be effectively addressed this way. Indeed, the great majority of successful antibody drugs bind one of a handful of targets because of the often limited impact of simply binding to a target of interest.. Xencor takes a different approach, focusing its antibody engineering on the "stem" of the antibody - a region known as the Fc domain - which has proven to be a powerful new axis for differentiation and novel function. By fine-tuning the functionality of the Fc domain, Xencor develops XmAb antibody drug candidates with significantly improved potency, half-life and stability over existing antibodies, and open doors to biology previously inaccessible with traditional antibodies.. ...

- 5. The implantable device according to claim 1, wherein the material is selected from the group consisting of a metal, a metal alloy, a ceramic material, a natural or synthetic polymer and a composite thereof. (google.com)
- The other composite groups showed lower creep recovery as compared to the conventional material (GR). The creep strain % for all the bulk-fill composites materials were increased during immersion in the liquids. (mdpi.com)
- The aim of this study is to compare the creep/recovery behavior of bulk-fill dental composites after storage in various food simulating organic solvents. (mdpi.com)
- Moreover, SF2 resulted in the highest creep recovery in all of the composites groups, as well as conventional material. (mdpi.com)
- Glass-ionomer based hybrids incorporate another dental material, for example Resin-Modified Glass Ionomer Cements (RMGICs) and compomers (or modified composites). (wikipedia.org)
- This dental material has good adhesive bond properties to tooth structure, allowing it to form a tight seal between the internal structures of the tooth and the surrounding environment. (wikipedia.org)
- The acid produced from this metabolism results in the breakdown of tooth enamel and subsequent inner structures of the tooth, if the disease is not intervened by a dental professional, or if the carious lesion does not arrest and/or the enamel re-mineralises by itself. (wikipedia.org)
- Reports of the success rate of pulp capping treatments vary greatly and it is clear that in actual dental practice current procedures are not always effective. (marquette.edu)
- However, it is recommended that the use of fluoride varnish alongside glass ionomer sealants should be applied in practice to further reduce the risk of secondary dental caries. (wikipedia.org)
- Through the unique Dental Laboratory Technology Program situated at the well equipped laboratories at the SUNY Erie South Campus, students are instructed in all aspects of dental laboratory technology. (ecc.edu)
- The Dental Laboratory Technology laboratories at the South Campus have been designed to accommodate students confined to wheelchairs. (ecc.edu)
- Students who complete all the required courses in the Dental Laboratory Technology program and who use their SUNY Erie electives as advised can earn a B.S. in Professional & Technical Studies degree at Canisius. (ecc.edu)
- While most states set no minimum qualifications for dental lab technicians, some states require technicians to be certified by the National Board for Certification in Dental Laboratory Technology. (ecc.edu)
- Dental Laboratory Technology courses are offered at South Campus. (ecc.edu)
- Growth factors have been shown to induce the formation of reparative dentine and we have shown that they can protect dental pulp cells against toxicity induced by a number of insults. (marquette.edu)
