Hydroxyapatite-coated femoral stems. Histology and histomorphometry around five components retrieved at post mortem. (1/1071)

We performed a histological and histomorphometric examination in five cadaver specimens of the femoral and acetabular components and the associated tissue which had been recovered between 3.3 and 6.2 years after primary total hip arthroplasty (THA) using a proximal hydroxyapatite (HA)-coated titanium alloy implant. All had functioned well during the patients' life. All the stems were fixed in the femur and showed osseointegration of both the proximal and distal parts. The amount of residual HA was greatest in the distal metaphyseal sections, indicating that the rate of bone remodelling may be the main factor causing loss of HA. The level of activity of the patient was the only clinical factor which correlated with loss of coating. The percentage of bone-implant osseointegration was almost constant, regardless of the amount of HA residue, periprosthetic bone density or the time of implantation. HA debris was seldom observed and if present did not cause any adverse or inflammatory reaction. Partial debonding did occur in one case as a result of a polyethylene-induced inflammatory reaction.  (+info)

Coating titanium implants with bioglass and with hydroxyapatite. A comparative study in sheep. (2/1071)

This study compares the osteointegration of titanium implants coated with bioglass (Biovetro GSB formula) and with hydroxyapatite (HAP). Twenty-four bioglass-coated and 24 HAP-coated cylinders were implanted in the femoral diaphyses of sheep, and examined after 2, 4, 6, 8, 12, and 16 weeks. The HAP coating gave a stronger and earlier fixation to the bone than did bioglass. Bioglass formed a tissue interface which showed a macrophage reaction with little new bone formation activity. In contrast, HPA, showed intense new bone formation, with highly mineralised osseous trabeculae in the neighbourhood of the interface.  (+info)

The potent platelet inhibitory effects of S-nitrosated albumin coating of artificial surfaces. (3/1071)

OBJECTIVES: We studied the antithrombotic effect of coating glass, collagen and metal stent surfaces with bovine serum albumin (BSA) covalently modified to carry S-NO functional groups denoted (pS-NO-BSA). METHODS: Video-enhanced light microscopy was used to visualize canine blood platelet adhesion and aggregation in a parallel plate glass chamber. Platelet adhesion was observed for 60 min on glass, glass coated with BSA, glass coated with pS-NO-BSA, collagen I (CO) surface, CO coated with BSA and CO coated with pS-NO-BSA. We also coated Palmaz-Shatz (P-S) stents with pS-NO-BSA. Coated and uncoated stents were then immersed in porcine platelet-rich plasma for two min and the platelet cyclic GMP level was measured. In six anesthetized pigs, coated and uncoated stents were placed in the carotid arteries and [111In]-labeled platelets were circulated for 2 h. The stented arteries were then removed and placed in a gamma well counter. RESULTS: There was significantly less platelet attachment, adhesion and aggregation on the pS-NO-BSA coated surfaces compared with the BSA coated and uncoated surfaces. The pS-NO-BSA coating increased the platelet cGMP levels to 5.9+/-0.7 pmoles/10(8) platelets compared with 2.7+/-0.9 pmoles/10(8) platelets for control (p < 0.01). The average gamma ray count from [111In]-labeled platelets that attached to the coated stents was 90,000+/-42,000/min and 435,000+/-290,000/min for the uncoated stents (p < 0.01). CONCLUSIONS: The pS-NO-BSA coating of thrombogenic surfaces reduces platelet adhesion and aggregation, possibly by increasing the platelet cGMP. This inhibitory effect appears to be a consequence of the direct antiplatelet actions of NO combined with the antiadhesive properties of albumin.  (+info)

A comparative study of the rifampicin binding and elution characteristics for collagen- and albumin-sealed vascular grafts. (4/1071)

OBJECTIVES: To assess the rifampicin binding and elution characteristics for three protein-sealed vascular grafts. DESIGN: In vitro study. MATERIALS: Cardial and Hemashield collagen-sealed and the DeBakey/Vasculour albumin-sealed vascular grafts. METHODS: The grafts were soaked in a 60,000 mg/l solution of rifampicin at 37 degrees C for 15 min. Bound drug was eluted from the grafts at 37 degrees C and at timed intervals the concentrations of rifampicin remaining in the grafts were determined. RESULTS: Although all three grafts contained high concentrations of rifampicin immediately after soaking these rapidly fell on washing and only a small fraction of the adsorbed rifampicin was tightly bound to the grafts. Rifampicin loading of this tightly bound fraction was similar for the two collagen-sealed grafts (1.7-2.0 mg/kg) but higher for the albumin-sealed graft (16.0 mg/kg). Elution of the tightly bound fraction appeared to follow first-order kinetics with elimination half-lives of 89-141 h. The concentrations of rifampicin remaining in the grafts after eight days were above those needed to inhibit sensitive staphylococci and were 0.7 mg/kg (collagen-sealed grafts) to 3.7 mg/kg (albumin-sealed graft). CONCLUSIONS: There is broad equivalence between the rifampicin binding and elution for the two collagen-sealed grafts, but there appears to be slightly higher binding for the albumin-sealed graft.  (+info)

Radiologic and histopathologic evaluation of canine artery occlusion after collagen-coated platinum microcoil delivery. (5/1071)

BACKGROUND AND PURPOSE: Platinum coil embolization is one of the significant advances in interventional neuroradiologic techniques that has been introduced this decade. Our purpose was to evaluate the angiographic and histologic effects of collagen-coated platinum microcoil delivery in the canine artery. METHODS: We embolized the bilateral internal maxillary arteries of 18 dogs; one uncoated and one collagen-primed coil was used in each dog. We evaluated all coils by angiography, macroscopy, and scanning electron microscopy within 30 minutes of embolization. We then studied a proportional number of coated and collagen-primed coils at either 1 or 3 days, or 1, 2, 3, 4, 8, 12, or 16 weeks postoperatively. RESULTS: Six (33%) of 18 arteries embolized with uncoated coils were occluded 30 minutes after delivery, whereas 11 (61%) of 18 arteries treated with collagen-primed coils were occluded within 30 minutes of embolization. Late occlusion (3 weeks after embolization) occurred in 2 (25%) of 8 arteries embolized with untreated coils, and 6 (75%) of 8 arteries embolized with collagen-primed coils. We calculated differences in late occlusion rates by the chi2 (chi-square) test, and found these differences were significant (P=.04). Histologic findings of arteries embolized with unprimed coils revealed endothelial cell growth was limited to the organized thrombi 4 weeks after coil delivery. In contrast, endothelial cells grew directly on the collagen-primed coils 3 days postoperatively, and coils were completely covered by endothelial cells within 2 weeks. We found an organized thrombus in the inner space of coils in angiographically occluded arteries, a finding that was not evident in angiographically patent arteries. CONCLUSION: Collagen-coated platinum coils can produce rapid and stable occlusion of embolized vessels.  (+info)

Coating of extracorporeal circuit with heparin does not prevent sequestration of propofol in vitro. (6/1071)

Propofol is sequestered in extracorporeal circuits, but the factors responsible for the phenomenon are mostly unknown. We have compared two extracorporeal circuits (oxygenators, reservoirs and tubings) coated with heparin with two corresponding uncoated circuits for their capacity to sequester propofol in vitro. Three experiments were conducted with each circuit. The circuit was primed with a mixture of Ringer's acetate solution and whole blood, and the study conditions (pump flow, temperature, pH) were standardized. Propofol was added to the solution to achieve a concentration of 2 micrograms ml-1. These studies were followed with concentrations of 10- and 100-fold to assess possible saturation of propofol binding. Serial samples were obtained from the circulating solution for measurement of propofol concentration. Propofol concentrations decreased to 22-32% of the initial predicted concentration of 2 micrograms ml-1 in the circuits (no significant difference between circuits). With greater concentrations, the circuits did not become saturated with propofol, even with the highest predicted concentration of 200 micrograms ml-1. We conclude that propofol was sequestered in extracorporeal circuits in vitro, irrespective of coating the circuit with heparin.  (+info)

An ex vivo investigation into the bond strength of orthodontic brackets and adhesive systems. (7/1071)

The aim of this study was to compare the shear bond strength of Adhesive Precoated Brackets (APC) with that of two types of uncoated bracket bases, Straight-Wire and Dyna-Lock. Two types of orthodontic adhesives were used, Transbond XT and Right-On. Three different curing times were evaluated with the APC brackets in order to find the best. Adhesive remnants on the enamel surface following debond were evaluated using the Adhesive Remnant Index (Artun and Bergland, 1984). Bond strengths ranged from 11.00 to 22.08 MPa. For both types of brackets Transbond produced a significant increase in bond strength compared to Right-On. The Dyna-Lock/Right-On combination produced the poorest results. APC brackets cured for 40 s had similar bond strengths to uncoated brackets fixed by means of Transbond. Overall, 79 per cent of specimens had less than half the tooth surface covered with adhesive following debond. Significantly more adhesive remained on tooth surfaces following debond of the Straight-Wire/Right-On group than any other bracket/adhesive combination. Bond strengths were higher with light-cured Transbond than with chemically-cured Right-On. When Transbond is used in association with APC brackets a 40-second cure time is recommended.  (+info)

Polyethylene wear, osteolysis and acetabular loosening with an HA-coated hip prosthesis. A follow-up of 94 consecutive arthroplasties. (8/1071)

We have followed up for a period of seven to nine years 100 consecutive arthroplasties of the hip in which an entirely HA-coated implant had been used. The clinical results were excellent and bony incorporation was extensive in all components. No stem became loose or subsided but five cups were revised because of loosening after 3.8 to 5.5 years, having functioned painlessly and shown radiological ingrowth. Revision procedures because of excessive polyethylene wear have been performed on 18 hips and are planned for six more. Two eroded metal backings with worn-through polyethylene were exchanged; six hips showed metallosis without polyethylene wear-through. There were two cases of granulomatous cysts in the groin and 66 hips had osteolysis located periarticularly, in the greater trochanter or in the acetabulum.  (+info)

The use of drug-eluting stents (DES) has led to a drastic reduction of restenosis rates compared to bare metal stents (BMS), but 5% to 10% of patients receiving DES are still in need of revascularization of the treated vessel. Two important families of drugs are used for stent coating: paclitaxel belonging to the taxane family, and the limus-family such as sirolimus, everolimus, zotarolimus, biolimus A9 and pimecrolimus.. Data regarding the optimal treatment of in-DES-restenosis is very limited. Implanting a new DES for in-DES-restenosis has been reported to be associated with re-restenosis rates as high as 43%. Several recent well published studies have shown a substantial reduction of restenosis using paclitaxel-eluting balloons (PEB) for de-novo lesions and BMS-restenotic lesions.. The objective of this randomized trial is to assess the hypothesis, that PEB are non-inferior to paclitaxel-eluting-stents (PES) for restenosis in limus-eluting-stents (LES), and both, PEB and PES, are superior ...

Multiple randomized clinical trials and pooled analyses have shown improved clinical outcomes of primary PCI when compared with fibrinolytic therapy. Primary PCI for STEMI results in greater patency of the infarct-related artery (IRA) and lower rates of death, re-infarction, and stroke when compared with fibrinolysis. The use of coronary stents has reduced the need for repeat revascularization in patients treated with primary PCI. However, in the setting of STEMI this reduction in target lesion revascularization (TLR) did not reduce re-infarction rates or both short term and long-term mortality rates. This was confirmed by a large meta-analysis by De Luca et al, using 13 randomized trials and involving 6922 patients. In studies evaluating DES versus BMS in STEMI mortality rates are similar in patients treated with BMS or DES. Although TLR rates are reduced with the use of DES, there have been concerns about long-term delay of arterial healing produced by both the Cypher DES and Taxus DES and the ...

Methods of color matching a coating having a metallic flake distribution within the coating are included using reflectance factors and tristimulus values and minimizing the sum of the squares of the deviation between samples.
It would absolutely work!. The aluminium wire would have to be wrapped around, or sitting on top of, something made from tungsten or molybdenum because aluminium will definitely melt. Unfortunately the chamber, aluminium wire and plastic part would have to be super clean or the film will come out golden brown (Ive seen this happen). The "dirtiest" part of the film is the first part to be deposited, so the quality of the film will still need to be decent even to just view through the plastic. I helped someone make "disposable electrodes" for a plasma physics experiment by coating an acrylic disc with aluminium; theyd then blow it off will a few megavolts to study the plasma it made, then wed re-coat it. It worked like a charm.. Youd need more than just a rotary vacuum pump though: you could use a titanium evaporation in another part of the chamber to increase the vacuum :). You could also try using some gallium to coat the plastic part, that should leave a nice shiny plastic-metal interface ...

... ARE AN ALTERNATIVE TO organic or polymer based coatings for selected surface coating applications. When protecting a surface, it is usually less expensive to use organic coatings rather than other materials such as ceramic coatings. However, organic paints have limitations and will not meet all service requirements. Though more expensive, for some applications ceramic coatings may be a more suitable form of protection. Vitreous (glassy) ceramic coatings are chosen for application over a substrate for one or more of several reasons [1]. These reasons for selecting a ceramic coating in preference to an organic paint include rendering the surface more chemically inert, impervious to liquids and gases, more readily cleanable, and more resistant to service temperature, abrasion, and scratching. The chemical durability of ceramic coatings in service substantially exceeds that of organic paints [2]. Vitreous coatings are formulated to be resistant to a variety of reagents, from acids ...

Thick opaque ceramic coatings are used to protect delicate microelectronic devices against excited energy sources, radiation, light, abrasion, and wet etching techniques. The thick opaque ceramic coating are prepared from a mixture containing phosphoric anhydride, i.e., phosphorous pentoxide (P2 O5), and a pre-ceramic silicon-containing material. It is preferred to also include tungsten carbide (WC) and tungsten metal (W) in the coating mixture. The coating is pyrolyzed to form a ceramic SiO2 containing coating. A second coating of plasma enhanced chemical vapor deposited (PECVD) silicon carbide (SiC), diamond, or silicon nitride (Si3 N4), can be applied over the thick opaque ceramic coating to provide hermeticity. These coatings are useful on patterned wafers, electronic devices, and electronic substrates. The thick opaque ceramic coating is unique because it is resistant to etching using wet chemicals, i.e., acids such as H3 PO4 and H2 SO4, or bases.

The clinical success of a bone-anchored implant is controlled by many factors such as implant shape, chemical composition, mechanical and surface properties. The surface properties (e.g. charge, wettability and roughness) are considered to be important parameters for the biological acceptance of the biomaterial, whereas the bulk properties control the biomechanical behaviour. For implants designed to be used in load-bearing applications in the skeletal system, the biomaterial should preferably integrate into bone tissue for a long lasting function. Lack of integration between the implant and bone increases the risk of micromotions, infections, soft tissue encapsulation, which all reduces the survival rate of the implant and makes revision surgery necessary. Coatings and surface modifications can be used to tailor properties of implant surfaces, and further improve the potential bone bonding and bone in-growth, compared to unmodified surfaces. A biomimetic method, developed by Kokubo, can be used ...
Drug-coated/drug-eluting balloons (DCB/DEB) have been shown to be very effective in treatment of patients with DES-ISR [4]. According to a single-center, randomized study, DCB showed better clinical and angiographic results in treatment of DES-ISR in comparison to BA [9]. The PEPCAD-DES study, a prospective, multicenter, randomized trial of 110 randomly assigned patients, comparing the impact of paclitaxel-coated balloon angioplasty for treatment of DES-ISR versus conventional BA showed that paclitaxel-coated balloon angioplasty was superior to BA alone for treatment of DES-ISR [10]. In addition, ISAR-DESIRE 3 study, a prospective, randomized, multicenter clinical trial including 402 patients with "limus"-DES-ISR comparatively investigated the efficacy of paclitaxel-eluting balloon versus paclitaxel-eluting stent versus BA alone and confirmed that DCB/DEB was non-inferior to PES and that both DCB/DEB and PES were superior to BA alone in treatment of DES-ISR [11]. Available data from these ...
Bacterial infection from medical devices is a major problem and accounts for an increasing number of deaths as well as high medical costs. Many different strategies have been developed to decrease the incidence of medical device related infection. One way to prevent infection is by modifying the surface of the devices in such a way that no bacterial adhesion can occur. This requires modification of the complete surface with, mostly, hydrophilic polymeric surface coatings. These materials are designed to be non-fouling, meaning that protein adsorption and subsequent microbial adhesion are minimized. Incorporation of antimicrobial agents in the bulk material or as a surface coating has been considered a viable alternative for systemic application of antibiotics. However, the manifestation of more and more multi-drug resistant bacterial strains restrains the use of antibiotics in a preventive strategy. The application of silver nanoparticles on the surface of medical devices has been used to prevent

TY - JOUR. T1 - Significance of calcium phosphate coatings for the enhancement of new bone osteogenesis - A review. AU - Surmenev, Roman A.. AU - Surmeneva, Maria A.. AU - Ivanova, Anna A.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - A systematic analysis of results available from in vitro, in vivo and clinical trials on the effects of biocompatible calcium phosphate (CaP) coatings is presented. An overview of the most frequently used methods to prepare CaP-based coatings was conducted. Dense, homogeneous, highly adherent and biocompatible CaP or hybrid organic/inorganic CaP coatings with tailored properties can be deposited. It has been demonstrated that CaP coatings have a significant effect on the bone regeneration process. In vitro experiments using different cells (e.g. SaOS-2, human mesenchymal stem cells and osteoblast-like cells) have revealed that CaP coatings enhance cellular adhesion, proliferation and differentiation to promote bone regeneration. However, in vivo, the exact mechanism of ...

Medical devices implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to help - blood clotting and bacterial infection. Researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a new surface coating for medical devices using FDA-approved materials. The super-repellent coating can be adhered to existing, approved medical devices. In a two??step surface??coating process, the researchers chemically attached a monolayer of perfluorocarbon, which is similar to Teflon. Then they added a layer of liquid perfluorocarbon, which is widely used in medicine for applications such as eye surgery. The team calls the tethered perfluorocarbon plus the liquid layer a Tethered??Liquid Perfluorocarbon surface, or TLP for short. The coating successfully repelled blood from more than 20 medically relevant substrates the team tested - made of plastic to glass and metal - and

Nanoscale Hydrogel Coatings on Cells. Abstract. The manipulation of biological function on the cellular and subcellular level holds great potential for innovation in medical diagnostics and treatment. Central to this manipulation is the interface of the biological species and its surroundings. Polymeric coatings are obvious choices for biointerfaces as they can mimic the biological environment in structure and chemical functionality and are readily tuned owing to their wide variation in architecture, mechanical properties, surface energy and transport properties.. This talk will focus on the formation of an interfacial polymer network as a tool to control transport of materials at a mammalian cell membrane. The discussion will be is focused on applications of cellular coatings for cellular sorting. An entirely new approach to cellular sorting will be presented that is based on the selective deposition of a protective coating on a cell and the destruction of all unprotected cells. This new batch ...
The research of hard protective coatings is distictively application-oriented, as the main goal is to increase the lifetime of tools in the machining environment. Optimal combination of properties required for hard coatings can only be achieved by an in-depth study in several levels: understanding the process of coating growth, analysis of influence of deposition parameters on coating properties, and analysis of coating wear processes. The topic is distinctively interdisciplinary, encompassing plasma physics, physics and chemistry of surfaces, metallurgy, materials science and mechanical engineering. Beside a targeted development of a coating for specific technological application, the study of above mentioned processes contributes to a general knowledge of deposition and application of hard coatings. The most important materials for hard coatings are transition metal nitrides, but the department is doing research on other materials such as diamond-like coatings, quasicrystals, oxides, etc. The ...
