Association of plasma fibrinogen concentration with vascular access failure in hemodialysis patients. (1/3384)

BACKGROUND: Elevated plasma fibrinogen is an important risk factor for coronary artery disease in the general population and patients with chronic renal failure. High plasma fibrinogen may trigger thrombus formation in arteriovenous fistulas. We performed a prospective, cohort study to evaluate the association of plasma fibrinogen concentration with vascular access failure in patients undergoing long-term haemodialysis. METHODS: Between September 1989 and October 1995, 144 patients underwent a vascular access operation. In March 1997, 102 patients (56 M, 46 F) who had been followed up for more than 18 months (median; 37 months, range; 18-102 months) were included in the study. The median age of the patients was 52 years (range; 19-78 years). In 35 patients, renal disease was secondary to diabetes mellitus. The type of vascular access was a polytetrafluoroethylene (PTFE) graft in 17 patients. Seventy-seven patients received recombinant human erythropoietin (r-HuEPO) therapy during the follow-up period. Plasma fibrinogen, albumin, total cholesterol, hematocrit, platelets and creatinine were measured at the time of operation. Vascular access failure was defined as the occurrence of complications requiring transluminal angioplasty, thrombolytic therapy or surgical repair. RESULTS: Thirty-eight patients had at least one vascular access failure and the incidence was 0.3 (range; 0-2.4) episodes per patient-year. The survival rate of vascular access was 78% (native fistula; 80%, PTFE graft; 71%) after 12 months and 70% (native fistula; 73%, PTFE graft; 51%) after 24 months. Older age, a PTFE graft, r-HuEPO therapy, higher hematocrit, lower albumin and higher fibrinogen levels were significantly associated with vascular access failure, whereas gender, diabetes mellitus, total cholesterol and platelet count were not. Plasma fibrinogen was inversely correlated with albumin (r=-0.38, P=0.001). The cumulative vascular access survival was significantly lower in patients with high plasma fibrinogen levels (> or = 460 mg/dl) compared with patients with low levels (< 460 mg/dl) (P=0.007). Independent risk factors for vascular access failure analysed by Cox's proportional hazards model were older age (RR; 1.36 by 10-year increment), higher fibrinogen level (RR; 1.20 by 100 mg/dl increment), PTFE graft (RR; 2.28) and r-HuEPO therapy (RR; 3.79). CONCLUSION: High plasma fibrinogen level is an independent risk factor for vascular access failure in haemodialysis patients.  (+info)

Transdermal photopolymerization for minimally invasive implantation. (2/3384)

Photopolymerizations are widely used in medicine to create polymer networks for use in applications such as bone restorations and coatings for artificial implants. These photopolymerizations occur by directly exposing materials to light in "open" environments such as the oral cavity or during invasive procedures such as surgery. We hypothesized that light, which penetrates tissue including skin, could cause a photopolymerization indirectly. Liquid materials then could be injected s.c. and solidified by exposing the exterior surface of the skin to light. To test this hypothesis, the penetration of UVA and visible light through skin was studied. Modeling predicted the feasibility of transdermal polymerization with only 2 min of light exposure required to photopolymerize an implant underneath human skin. To establish the validity of these modeling studies, transdermal photopolymerization first was applied to tissue engineering by using "injectable" cartilage as a model system. Polymer/chondrocyte constructs were injected s.c. and transdermally photopolymerized. Implants harvested at 2, 4, and 7 weeks demonstrated collagen and proteoglycan production and histology with tissue structure comparable to native neocartilage. To further examine this phenomenon and test the applicability of transdermal photopolymerization for drug release devices, albumin, a model protein, was released for 1 week from photopolymerized hydrogels. With further study, transdermal photpolymerization potentially could be used to create a variety of new, minimally invasive surgical procedures in applications ranging from plastic and orthopedic surgery to tissue engineering and drug delivery.  (+info)

Defensins impair phagocytic killing by neutrophils in biomaterial-related infection. (3/3384)

The implantation of foreign material carries a risk of infection which frequently is resistant to all treatment short of removing the implant. We have previously shown that these materials activate neutrophils by contact, leading to production of oxygen free radicals accompanied by release of granule products. Such activation further results in depletion of local host defenses, including the capacity of biomaterial-activated neutrophils to kill bacteria. Among the granule products released from neutrophils are small cationic antibacterial peptides (human neutrophil peptides [HNP]) known as defensins. Here we tested the hypothesis that defensins, released from activated neutrophils onto the surface of biomaterials, might play a role in the deactivation of subsequent neutrophil populations. Incubation of neutrophils with purified HNP resulted in a dose-related impairment of stimulus-induced oxygen radical production and of phagocytic killing. Furthermore, fresh neutrophils added to biomaterial-associated neutrophils exhibited impaired phagocytic killing. This impairment could be abrogated by antibody to HNP but not by an irrelevant antibody. Taken together, these observations support the idea that neutrophils activated at a material surface can create, by means of HNP release, an environment hostile to their microbicidal function and that of their infiltrating brethren.  (+info)

Cylindrical or T-shaped silicone rubber stents for microanastomosis--technical note. (4/3384)

The ostium of the recipient artery and the orifice of the donor artery must be clearly visualized for the establishment of microvascular anastomosis. Specially designed colored flexible cylindrical or T-shaped silicone rubber stents were made in various sizes (400 or 500 microns diameter and 5 mm length) and applied to bypass surgery in patients with occlusive cerebrovascular disease such as moyamoya disease and internal carotid artery occlusion. The colored flexible stents facilitated confirmation of the ostium of the artery even in patients with moyamoya disease and allowed precise microvascular anastomosis without problems caused by the stent.  (+info)

Effect of dialyser biocompatibility on recovery from acute renal failure after cadaver renal transplantation. (5/3384)

BACKGROUND: It has been reported that patients with acute renal failure (ARF) requiring haemodialysis show an improved recovery of renal function when the dialysis treatment is performed using a biocompatible membrane rather than a bioincompatible membrane. However, most recent published human trials have not been able to confirm these findings. METHOD: Over a 2-year period, we prospectively studied 53 patients with ARF after cadaver renal transplantation who required haemodialysis and randomized them into two treatment groups. One group underwent dialysis with a cuprophane membrane and the other group underwent haemodialysis with a more biocompatible membrane, polysulfone. All patients received an immunosuppressive regimen which included azathioprine, prednisone and cyclosporine. RESULTS: There was no difference by patient characteristics or immunosuppressive regimen before acute tubular necrosis (ATN) recovery. In both groups the number of haemodialysis sessions required prior to the recovery of renal function (6.57+/-2.79 vs 6.05+/-2.40), the number of oliguric days (16.25+/-5.14 vs 14.40+/-4.67) and the number of hospital days (33.38+/-12.85 vs 30.10+/-11.00), were not statistically different. There was also no difference in long-term allograft outcome. CONCLUSION: Our data demonstrate that the use of a more biocompatible membrane had no influence on the recovery from acute renal failure after renal transplantation.  (+info)

Noninvasive measurement of anatomic structure and intraluminal oxygenation in the gastrointestinal tract of living mice with spatial and spectral EPR imaging. (6/3384)

EPR imaging has emerged as an important tool for noninvasive three-dimensional (3D) spatial mapping of free radicals in biological tissues. Spectral-spatial EPR imaging enables mapping of the spectral information at each spatial position, and, from the observed line width, the localized tissue oxygenation can be mapped. We report the development of EPR imaging instrumentation enabling 3D spatial and spectral-spatial EPR imaging of small animals. This instrumentation, along with the use of a biocompatible charcoal oximetry-probe suspension, enabled 3D spatial imaging of the gastrointestinal (GI) tract, along with mapping of oxygenation in living mice. By using these techniques, the oxygen tension was mapped at different levels of the GI tract from the stomach to the rectum. The results clearly show the presence of a marked oxygen gradient from the proximal to the distal GI tract, which decreases after respiratory arrest. This technique for in vivo mapping of oxygenation is a promising method, enabling the noninvasive imaging of oxygen within the normal GI tract. This method should be useful in determining the alterations in oxygenation associated with disease.  (+info)

A tissue engineering approach was developed to produce arbitrary lengths of vascular graft material from smooth muscle and endothelial cells that were derived from a biopsy of vascular tissue. Bovine vessels cultured under pulsatile conditions had rupture strengths greater than 2000 millimeters of mercury, suture retention strengths of up to 90 grams, and collagen contents of up to 50 percent. Cultured vessels also showed contractile responses to pharmacological agents and contained smooth muscle cells that displayed markers of differentiation such as calponin and myosin heavy chains. Tissue-engineered arteries were implanted in miniature swine, with patency documented up to 24 days by digital angiography.  (+info)

Thrombopoietin stimulates endothelial cell motility and neoangiogenesis by a platelet-activating factor-dependent mechanism. (8/3384)

In this study, we demonstrate that human umbilical cord vein-derived endothelial cells (HUVECs) expressed c-Mpl, the thrombopoietin (TPO) receptor, and that TPO activates HUVECs in vitro, as indicated by directional migration, synthesis of 1-alkyl-/1-acyl-platelet-activating factor (PAF) and interleukin-8 (IL-8), and phosphorylation of the signal transducers and activators of transcription (STAT) STAT1 and STAT5B. The observation that WEB 2170 and CV3988, 2 structurally unrelated PAF receptor antagonists, prevented the motility of HUVECs induced by TPO suggests a role of PAF as secondary mediator. Moreover, kinetic analysis of TPO-induced tyrosine phosphorylation of STAT demonstrated that STAT5B activation temporally correlated with the synthesis of PAF. PAF, in turn, induced a rapid tyrosine phosphorylation of STAT5B and PAF receptor blockade, by WEB 2170, preventing both TPO- and PAF-mediated STAT5B activation. The in vivo angiogenic effect of TPO, studied in a mouse model of Matrigel implantation, demonstrated that TPO induced a dose-dependent angiogenic response that required the presence of heparin. Moreover, the in vivo angiogenic effect of TPO was inhibited by the PAF receptor antagonist WEB 2170 but not by the anti-basic fibroblast growth factor neutralizing antibody. These results indicate that the effects of TPO are not restricted to cells of hematopoietic lineages, because TPO is able to activate endothelial cells and to induce an angiogenic response in which the recruitment of endothelial cells is mediated by the synthesis of PAF. Moreover, biochemical analysis supports the hypothesis that STAT5B may be involved in the signaling pathway leading to PAF-dependent angiogenesis.  (+info)

A prosthesis is formed from a biocompatible material having one or more associated cell adhesion stimulating proteins. The biocompatible material can be a ceramic material or a carbon coated material. The cell adhesion stimulating protein can be a structural protein or a polypeptide growth factor, such as vascular endothelial growth factor. Viable cells can be adhered in vivo or in vitro to the biocompatible material with the cell adhesion stimulating protein.
Cell-material adhesions are fundamental in cell biology. Not only the chemical identity of the material, but also the spatial and temporal presentation of the adhesion molecules determine how different cell types interact with a material and activate signaling. Hence, the design of cell-instructive materials for studying cell biology and applications in tissue engineering, medical implants and cell-based screening all require independent spatiotemporal control of cell-material interactions, not just for one but for multiple cell types. By using photoswitchable proteins that respond to different colors of light, we want to photochemically control the cell-material interactions for multiple cell types. Manipulating cell-material interactions photochemically will give us control over cell adhesion with high spatial and temporal resolution, making it possible to study and manipulate intercellular processes such as collective cell migration and differentiation, and intracellular processes such as ...

A flexible stent having a waveform pattern formed from a sheet of biocompatible material and into a tubular shape for maintaining the patency of a lumen such as in a coronary vessel. The waveform pattern of the stent is formed from a flat sheet of malleable, biocompatible material by, for example, photochemically etching the sheet and leaving a framework or plurality of closed cells. The waveform pattern is formed into a tubular shape around a deflated, delivery catheter balloon with segments of the closed cells being interposed only overlapping a reinforcing member extending longitudinally along the stent. The stent material is treated to reduce the coefficient of friction of the material and to aid in the radial expansion of the stent with the balloon. Radiopaque markers are positioned at the ends of the stent to aid the physician in positioning the stent at an occlusion site.
Background The cell-material interaction is a complex bi-directional and dynamic process that mimics to a certain extent the natural interactions of cells with the extracellular matrix. Cells tend to adhere and rearrange adsorbed extracellular matrix (ECM) proteins on the material surface in a fibril-like pattern. Afterwards, the ECM undergoes proteolytic degradation, which is a mechanism for the removal of the excess ECM usually approximated with remodeling. ECM remodeling is a dynamic process that consists of two opposite events: assembly and degradation. Methodology/Principal Findings This work investigates matrix protein dynamics on mixed self-assembled monolayers (SAMs) of -OH and -CH3 terminated alkanethiols. SAMs assembled on gold are highly ordered organic surfaces able to provide different chemical functionalities and well-controlled surface properties. Fibronectin (FN) was adsorbed on the different surfaces and quantified in terms of the adsorbed surface density, distribution and

The frame is attached to the base layer such that the biocompatible material forms a membrane extending along and between the arcuate legs.
Ver más] Tissue engineering is an emerging field of research which combines the use of cell-seeded biomaterials both in vitro and/or in vivo with the aim of promoting new tissue formation or regeneration. In this context, how cells colonize and interact with the biomaterial is critical in order to get a functional tissue engineering product. Cell-biomaterial interaction is referred to here as the phenomenon involved in adherent cells attachment to the biomaterial surface, and their related cell functions such as growth, differentiation, migration or apoptosis. This process is inherently complex in nature involving many physico-chemical events which take place at different scales ranging from molecular to cell body (organelle) levels. Moreover, it has been demonstrated that the mechanical environment at the cell-biomaterial location may play an important role in the subsequent cell function, which remains to be elucidated. In this paper, the state-of-the-art research in the physics and mechanics ...
Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. In this thesis, titanium dioxide (TiO2)-associated photocatalysis under ultraviolet (UV) irradiation was investigated as a strategy for developing bioactivity and antibacterial properties on biomaterials. Although much of the work was specifically directed towards dental materials, the results presented are applicable to a wide range of biomaterial applications.. Most of the experimental work in the thesis was based on a resin-TiO2 nanocomposite that was prepared by adding 20 wt% TiO2 nanoparticles to a resin-based polymer material. Tests showed that the addition of the nanoparticles endowed the adhesive material with photocatalytic activity without affecting the functional bonding strength. Subsequent studies indicated a ...
AbstractOptical technologies are essential for the rapid and efficient delivery of health care to patients. Efforts have begun to implement these technologies in miniature devices that are implantable in patients for continuous or chronic uses. In this review, we discuss guidelines for biomaterials suitable for use in vivo. Basic optical functions such as focusing, reflection, and diffraction have been realized with biopolymers. Biocompatible optical fibers can deliver sensing or therapeutic-inducing light into tissues and enable optical communications with implanted photonic devices. Wirelessly powered, light-emitting diodes (LEDs) and miniature lasers made of biocompatible materials may offer new approaches in optical sensing and therapy. Advances in biotechnologies, such as optogenetics, enable more sophisticated photonic devices with a high level of integration with neurological or physiological circuits. With further innovations and translational development, implantable photonic devices offer a
Center for Hierarchical Manufacturing: Diseases and disorders of cartilage tissue are one of the leading causes of disability in the US. However, many biocompatible materials do not have sufficient mechanical strength and elasticity to serve as scaffolds for cartilage repair. University of Massachusetts Amherst researchers Surita Bhatia and Gregory Tew have developed techniques to disperse nanosized discs within biocompatible polymer matrices, resulting in biocompatible gels with superior control over mechanical properties. By varying the loading and surface chemistry of the nanodiscs, the elasticity of these materials can be tuned to match the mechanical properties of several soft tissues, including cartilage. Initial results also suggest that the presence of the nanodiscs result in improved cell viability.. ...
Microfabricated systems provide an excellent platform for the culture of cells, and are an extremely useful tool for the investigation of cellular responses to various stimuli. Advantages offered over traditional methods include cost-effectiveness, controllability, low volume, high resolution, and sensitivity. Both biocompatible and bioincompatible materials have been developed for use in these applications. Biocompatible materials such as PMMA or PLGA can be used directly for cell culture. However, for bioincompatible materials such as silicon or PDMS, additional steps need to be taken to render these materials more suitable for cell adhesion and maintenance. This review describes multiple surface modification strategies to improve the biocompatibility of MEMS materials. Basic concepts of cell-biomaterial interactions, such as protein adsorption and cell adhesion are covered. Finally, the applications of these MEMS materials in Tissue Engineering are presented.
Edited by: Prof Jeong-Yeol Yoon. The well-studied tissue interaction with biomaterials has inspired a blossoming field of alternative uses for these substrates. Current methods for scaffold fabrication include hydrogels, 3D printed biocompatible materials, and other bio-inspired tissue engineered implants. Traditional study of such biomaterials has primarily focused on the implants used in vivo. The recent surge in alternative uses for biomaterials has pushed for the investigation of intravenous drug and gene delivery carriers and the use of biomaterials for lab-on-a-chip (LOC) applications, particularly stem cell differentiation and cancer studies.

A continuous glucose sensor employing radio frequency (RF) signals is presented using the biocompatible material Silicon Carbide (SiC). Unlike biosensors that require direct contact with interstitial fluids to trigger chemical reactions to operate, this biocompatible SiC sensor does not require a direct interface. The sensing mechanism for this SiC sensor is based upon a shift in resonant frequency, as a function of change in glucose levels, which electrically manifests itself as a change in blood permittivity and conductivity. For in vivo applications the antenna sensor needs to operate inside the body environment, and it has been found that the best operational location of this biocompatible SiC sensor is within fatty tissue in close proximity to blood vessels. To test glucose levels, measurements using synthetic body fluid (SBF), which is electrically equivalent to blood plasma, were performed. Changes in sensor performance to varying glucose levels were measured and a shift in resonant frequency to
Biocompatible and biodegradable fibrinogen microspheres for tumor-targeted doxorubicin delivery Jae Yeon Joo, GilYong Park, SeongSoo A An Department of Bionano Technology, Gachon Medical Research Institute, Gachon University, Seongnam-si, Republic of Korea Abstract: In the development of effective drug delivery carriers, many researchers have focused on the usage of nontoxic and biocompatible materials and surface modification with targeting molecules for tumor-specific drug delivery. Fibrinogen (Fbg), an abundant glycoprotein in plasma, could be a potential candidate for developing drug carriers because of its biocompatibility and tumor-targeting property via arginine–glycine–aspartate (RGD) peptide sequences. Doxorubicin (DOX), a chemotherapeutic agent, was covalently conjugated to Fbg, and the microspheres were prepared. Acid-labile and non-cleavable linkers were used for the conjugation of DOX to Fbg, resulting in an acid-triggered drug release under a mild acidic condition and a slow

3. After the space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.. ...
Next, a small opening is made in the surface of the affected tooth to give access to the pulp chamber and root canals. Tiny instruments are used, sometimes with the aid of a microscope, to remove the dead and dying pulp tissue from inside these narrow passageways. The chamber and empty canals are then cleaned, disinfected, and prepared to receive a filling of inert, biocompatible material. Finally, adhesive cement is used to seal the opening in the tooth, preventing future infection.. Following root canal treatment, your tooth may feel some sensitivity or tenderness for a few days. Over-the-counter pain relievers like ibuprofen are generally effective in relieving discomfort, but prescription medications may also be given if needed. During this period, it may help to avoid biting hard on the affected tooth. All of these symptoms, however, should be temporary.. To further protect the tooth and restore it to full function, its usually necessary to have a crown or other restoration placed on it. ...

Wearable medical devices such as continuous heart rate monitors, insulin pumps, and neural stimulators usually need access to an electric power source in order to function. While theres a great deal of wasted energy that our body emits that can be harvested to power such devices, making it actually happen using biocompatible materials has proven to be challenging. Now, a team of engineers at Purdue University has shown that polyvinyl alcohol (PVA), one of the most common polymers used in biomedicine, can be used to produce efficient triboelectric nanogenerators (TENGs) that can also act as cardiac activity monitors.. The PVA-based TENGs show great potential for self-powered biomedical devices and open doors to new technologies that use widely deployed biocompatible materials for economically feasible and ecologically friendly production of functional devices in energy, electronics and sensor applications, said Wenzhuo Wu, the leader of the research team.

Biomaterials are further evolving. Biomaterials for hearing implants depend on components, structural polymers, and electrodes. Biomaterials have transformed the medical treatment of hearing loss. The ear dysfunction, hearing loss is able to be addressed and repaired via a device implant that leverages biomaterials. Alloplastic and homograft biomaterials have been used to restore hearing with ossicular replacement prostheses, cochlear implants, and implantable middle ear devices. Biomaterials are used in implantable middle ear devices and inner ear implants. Biomaterials for middle ear applications of implantable devices are significant. The site of implantation and the mass of the implant dictate the choice of biomaterials. Hermetic sealing of an implant is best achieved by the use of metals, not polymers. The Osteocompatibility of an ossicular implant can be enhanced by the incorporation of calcium phosphates such as hydroxyapatite coatings. The market research study provides insight into market

This review discusses and summarizes the recent developments and advances in the use of biodegradable materials for bone repair purposes. The choice between using degradable and non-degradable devices for orthopedic and maxillofacial applications must be carefully weighed. Traditional biodegradable devices for osteosynthesis have been successful in low or mild load bearing applications. However, continuing research and recent developments in the field of material science has resulted in development of biomaterials with improved strength and mechanical properties. For this purpose, biodegradable materials, including polymers, ceramics and magnesium alloys have attracted much attention for osteologic repair and applications. The next generation of biodegradable materials would benefit from recent knowledge gained regarding cell material interactions, with better control of interfacing between the material and the surrounding bone tissue. The next generations of biodegradable materials for bone repair and
Polyimide (PI) is a commonly used polymer in microelectronics. Recently, numerous PI-based flexible neural interfaces have been developed for reducing mechanical mismatch between rigid implant and soft neural tissue. Most approaches employ non-photosensitive PI, which has been proven earlier to be biocompatible. However, photosensitive polyimide (PSPI) would simplify device fabrication remarkably, but its biocompatibility has been only sparsely reported. In this study, cytotoxicity of spin-coated PSPI (HD Microsystems PI-2771) and conventional PI (HD Microsystems PI-2525) films were evaluated in vitro using BHK-21 fibroblasts according to the ISO-10993-5 standard. PSPIs were tested as cured at a temperature of 200 degrees C (PI-2771-200) and 350 degrees C (PI-2771-350). The PI film surfaces were characterized in terms of their roughness, energy and zeta potential which are hypothesized to affect cell-material interactions. The values of the total surface free energy (SFE), and its polar and ...

To this aim, a series of non-polar azetidinones have been synthesized and characterized. The amount of azetidinones loaded on HA could be properly controlled on changing the polarity of the loading solution and it can reach values up to 17 wt%. ...
A multi-density polymeric interbody spacer formed from biocompatible material for osteoconductivity includes multiple density regions of different porosity to provide both strength and osteoconductivity. An interface region is formed between the density regions to provide both direct adhesion and mechanical interlocking between the different density regions to increase the strength of the multi-density polymeric interbody spacer. A method for forming the multi-density polymeric interbody spacer includes curing a first density region to achieve a first target porosity. A second density region may then be molded to the first density region to achieve a second target porosity. A portion of the second density region partially flows into pores of the first density region, providing direct adhesion and mechanical interlocking between the first and second density regions.
In recent years, the development and application of decellularized extracellular matrices (ECMs) for use as biomaterials have grown rapidly. These cell-derived matrices (CDMs) represent highly bioactive and biocompatible materials consisting of a complex assembly of biomolecules. Even though CDMs mimic the natural microenvironment of cells in vivo very closely, they still lack specifically addressable functional groups, which are often required to tailor a biomaterial functionality by bioconjugation. To overcome this limitation, metabolic glycoengineering has emerged as a powerful tool to equip CDMs with chemical groups such as azides. These small chemical handles are known for their ability to undergo bioorthogonal click reactions, which represent a desirable reaction type for bioconjugation. However, ECM insolubility makes its processing very challenging. In this contribution, we isolated both the unmodified ECM and azide-modified clickECM by osmotic lysis. In a first step, these matrices were ...
The hereditary hemophilias are the most common inherited severe bleeding disorders and are characterized by lifelong bleeding, both spontaneous, internal bleeding as well external bleeding due to injury, most commonly from surgical procedures. The current research grant proposes to develop a new biocompatible matrix employing nanotechnology that is hemostatic by incorporating a peptide that accelerates blood coagulation and will therefore stop bleeding. This peptide was discovered in my laboratory and reduces bleeding in animal models of hemorrhage. Therefore, attaching this peptide to „nanotechnology‟ based materials has great promise as a novel agent to reduce bleeding from external hemorrhagic injuries. The methodology will include utilizing standard biochemical techniques to characterize the material followed by the testing of the biocompatible material in animal models. The development of this product is especially relevant to the goals of the Canadian Hemophilia Society by discovering ...

Heterostructures of wide bandgap semiconductors such as silicon carbide (SiC) or group-III nitrides are attracting increasing interest for applications in the field of chemical and biological sensing. These biocompatible materials are particularly promising due to the possibility of bandgap engineering using the different SiC polytypes or AlxGa1-xN alloys, which could allow to optimize the charge transfer between the semiconductor device and the functional layer. A basic requirement for semiconductor biosensors based on organic-semiconductor hybrid structures is the direct covalent attachment of functional organic layers to the semiconductor surface. In my Ph.D. thesis, I systematically study different routes to obtain such functional layers on SiC and AlGaN alloys, including the silanization and hydrosilylation processes ...

Proplast: Polymer of polytetrafluoroethylene and carbon filaments; porous biocompatible material used in orofacial and middle ear reconstruction and as coating for metal implants.
Endodontic treatment can often be performed in one or two visits and involves the following steps:. The dentist examines and x-rays the tooth, then administers local anaesthetic. After the tooth is numb, the dentist places a small protective sheet called a dental dam over the area to isolate the tooth and keep it clean and free of saliva during the procedure.. The dentist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.. After the space is cleaned and shaped, the dentist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.. After the final visit with your dentist, you must return ...
The sooner you get treated for tooth decay, the less likely youll lose your tooth. That could mean a simple filling-or you might need a root canal treatment if decay has reached the inner pulp.. Theres also another procedure for advanced decay called pulp capping. Its a bit more involved than filling a cavity but less so than a root canal. We can use it if decay has exposed or nearly exposed the pulp, but not yet infected it-otherwise, you may still need a root canal treatment to remove the diseased pulp tissue.. There are two types of pulp capping methods, direct and indirect. We use direct pulp capping if the pulp has been exposed by decay. After isolating the tooth to protect other teeth from contamination, we remove all of the decayed dentin up to the pulp. This may cause some bleeding, which well stop, and then clean and dry the tooth area.. Well then apply a protective biocompatible material directly over the pulp to promote healing and protect it from further infection. We then ...

The chamber and empty canals are then cleaned, disinfected, and prepared to receive a filling of inert, biocompatible material. Finally, adhesive cement is used to seal the opening in the tooth, preventing future infection.. Following root canal treatment, your tooth may feel some sensitivity or tenderness for a few days. Over-the-counter pain relievers like ibuprofen are generally effective in relieving discomfort, but prescription medications may also be given if needed. During this period, it may help to avoid biting hard on the affected tooth. All of these symptoms, however, should be temporary.. To further protect the tooth and restore it to full function, its usually necessary to have a crown or other restoration placed on it. ...

In a study published in the Proceedings of the National Academy of Sciences, the patch lowered blood glucose in a mouse for 9 hours. Before the patch can be used in humans, clinical trials are needed. Said co-senior study author Zhen Gu, PhD, the patch works fast, is easy to use, and is made from nontoxic, biocompatible materials.. To comment on this article, contact [email protected] ...
Hypoxia in the tumor microenvironment (TME) mediates resistance to radiotherapy and contributes to poor prognosis in patients receiving radiotherapy. Here we report the design of clinically suitable formulations of hybrid manganese dioxide (MnO2) nanoparticles (MDNP) using biocompatible materials to reoxygenate the TME by reacting with endogenous H2O2. MDNP containing hydrophilic terpolymer-protein-MnO2 or hydrophobic polymer-lipid-MnO2 provided different oxygen generation rates in the TME relevant to different clinical settings. In highly hypoxic murine or human xenograft breast tumor models, we found that administering either MDNP formulation before radiotherapy modulated tumor hypoxia and increased radiotherapy efficacy, acting to reduce tumor growth, VEGF expression, and vascular density. MDNP treatment also increased apoptosis and DNA double strand breaks, increasing median host survival 3- to 5-fold. Notably, in the murine model, approximately 40% of tumor-bearing mice were tumor-free ...
There is a strong need of new materials to address current limitations in wound healing and in the translational aspects of wound healing. Progress in this area is limited by the void of information at the molecular level addressing cell-material interactions, at the tissue level addressing the evolution of implantable scaffolds and at the organ level addressing the development of new intervention methods to enhance healing. This thrust aims to create novel materials and experimental techniques to overcome these challenges. By tackling the steps between materials development and implantation, it is generating design rules and predictive models to determine the viability of a material in enhancing wound healing. Thrust Members:. ...
Theres a lot of interest in soft materials, particularly biomaterials, explains Guenther of the materials that help create functional tissue cultures, but until now no one has demonstrated a simple and scalable one-step process to go from microns to centimeters. How exactly does a machine grow a large patch of living tissue?. Scientists manipulate biomaterials into the micro-device through several channels. The biomaterials are then mixed, causing a chemical reaction that forms a mosaic hydrogel-a sheet-like substance compatible with the growth of cells into living tissues, into which different types of cells can be seeded in very precise and controlled placements.. Unique to this new approach to tissue engineering, however, and unlike more typical methods for tissue engineering (for instance, scaffolding, the seeding of cells onto an artificial structure capable of supporting three-dimensional tissue formation) cells planted onto the mosaic hydrogel sheets are precisely incorporated into ...

We report a highly biocompatible and practical protocol to create alginate microgels for bioactive encapsulation. Double-emulsion drops composed of dual cores enclosed by an ultrathin shell are prepared in a capillary microfluidic device, which exhibit selective coalescence between the cores. When the cores are laden with alginate precursors and divalent ions, respectively, coalescence leads to the formation of alginate microgels in the fused core of double-emulsion drops. The microgel can be rapidly released into a continuous water phase by rupturing the liquid shell. This method neither involves any toxic chemical cues for gelation nor long-term exposure to oil, thereby providing highly biocompatible encapsulation. ...

In addition to a material being certified as biocompatible, it is important that biomaterials are engineered specifically to their target application within a medical device. This is especially important in terms of mechanical properties which govern the way that a given biomaterial behaves. One of the most relevant material parameters is the Youngs Modulus, E, which describes a materials elastic response to stresses. The Youngs Moduli of the tissue and the device that is being coupled to it must closely match for optimal compatibility between device and body, whether the device is implanted or mounted externally. Matching the elastic modulus makes it possible to limit movement and delamination at the biointerface between implant and tissue as well as avoiding stress concentration that can lead to mechanical failure. Other important properties are the tensile and compressive strengths which quantify the maximum stresses a material can withstand before breaking and may be used to set stress ...
