Heart failure remains the leading cause of death in many industrialized nations owing to the inability of the myocardial tissue to regenerate. The main objective of this work was to develop a cardiac patch that is biocompatible and matches the mechanical properties of the heart muscle for myocardial infarction. The present study was to fabricate poly (glycerol sebacate)/gelatin (PGS/gelatin) core/shell fibers and gelatin fibers alone by electrospinning for cardiac tissue engineering. PGS/gelatin core/shell fibers, PGS used as a core polymer to impart the mechanical properties and gelatin as a shell material to achieve favorable cell adhesion and proliferation. These core/shell fibers were characterized by scanning electron microscopy, contact angle, Fourier transform infrared spectroscopy, and tensile testing. The cell-scaffold interactions were analyzed by cell proliferation, confocal analysis for the expression of marker proteins like actinin, troponin-T, and platelet endothelial cell adhesion ...
In the industrialized world, cardiovascular disease alone is responsible for almost half of all deaths. Many of the conditions can be treated successfully with surgery, often using transplantation techniques; however, autologous vessels or human-donated organs are in short supply. Tissue engineering aims to create specific, matching grafts by growing cells on appropriate matrices, but there are many steps between the research laboratory and the operating theatre. Neo-tissues must be effective, durable, non-thrombogenic and non-immunogenic. Scaffolds should be bio-compatible, porous (to allow cell/cell communication) and amenable to surgery. In the early days of cardiovascular tissue engineering, autologous or allogenic cells were grown on inert matrices, but patency and thrombogenicity of grafts were disappointing. The current ethos is toward appropriate cell types grown in (most often) a polymeric matrix that degrades at a rate compatible with the cells production of their own extracellular ...

A method for applying brazing material to an approximately metallic honeycomb body being wound, stratified or intertwined from at least partly structured sheet-metal layers, for brazing at least in partial regions, includes applying a thin film of a rolling oil to at least the structured sheet-metal layer, if such a film is not already present from production process; heat-treating the oil film to remove volatile components; placing regions of the sheet-metal layers to be provided with brazing material into contact with an aqueous solution of a surfactant; and putting the honeycomb bodies produced from the sheet-metal layers into contact with powdered brazing material adhering to locations where residues of the oil and the surfactant have come together. An apparatus for applying the brazing material to the honeycomb includes a heating station for passing a flow of hot air through a honeycomb body and heat-treating an oil film at a temperature of approximately 150 to 250 C. and preferably 200 to 230

Synthetic gecko-inspired adhesives rely on fibrillar structures that create non-chemical adhesion by concentrating intermolecular forces between two bodies, as discussed in recent reviews [1-3]. The potential to incorporate switchability in adhesion has only recently been explored. Examples include systems that respond to external stimuli such as temperature [4,5], magnetic field [6], mechanical deformation [7,8] and pneumatic pressure [9,10]. The common underlying principle is a reversible change in the area of contact between the adhesive surface and the test probe, leading to a change in adhesion.. In our previous work [8], the adhesion dependence on preload was established for polydimethylsiloxane (PDMS) fibrils with aspect ratio (AR) 3 (i.e. fibril height h divided by diameter d). Pull-off strengths at low preloads were high, whereas loss in adhesion was shown to occur at high preloads. The transition was due to a buckling instability of the fibrils at preloads higher than a critical value; ...

Researchers from Carnegie Melon University and Karlsruhe Institute of Technology have recently published an article in Journal of the Royal Society titled Staying Sticky: Contact Self-Cleaning of Gecko-Inspired Adhesives that presents the first gecko-inspired adhesive that matches both the attachment and self-cleaning properties of geckos foot on a smooth surface.. Using glass microspheres to simulate contamination the scientists created a synthetic gecko adhesive that could self-clean and recover lost adhesion. Real world applications of self-cleaning adhesives are reusable adhesive tapes, clothing, medical adhesives (bandages) and pick-and-place robots, among others.. Everyday challenge with traditional adhesives is that they loose their stickiness once contaminated. Geckos have been intriguing researchers for decades because of their unique and striking capability to maintain the stickiness of their toes through contact self-cleaning. They can travel up the walls and ceilings in a wide ...
In Intergel®, the hyaluronic acid is ionically crosslinked by iron, which slows absorption by the peritoneum. Intergel® provides a transient, viscous, lubricious coating on peritoneal surfaces following surgery. It is packaged in an accordion-like bottle for easy instillation to the surgical site. You don t need to be concerned about where you put Intergel® because intraperitoneal circulation will distribute the material along the peritoneal surfaces, Dr. diZerega said. However, because Intergel® is distributed, the entire bottle must be instilled so that efficacy is not compromised.. Dr. diZerega described a randomized, controlled, multicenter study, conducted by Johns and associates on 265 female patients undergoing laparotomy (Fertil Steril. 2001;76:595-604). Patients were treated with either Intergel® or lactated Ringer s solution. Follow-up laparoscopies were conducted and effectiveness was measured at 24 different abdominal and pelvic sites. The American Fertility Society (AFS) ...

Bringing new technologies to market is a challenging, time-consuming, and labor-intensive process. Dr. Alfred Crosby of the Department of Polymer Science and Engineering at UMass Amherst recalled that following a positive response to his labs development of a gecko-inspired adhesive platform technology, "our lab was launched into a media storm, which led to hundreds of inquiries from individuals and companies all over the world that wanted to use our technology in their products. This early attention made clear that a market existed for the technology, but it was less obvious how to best manage this transfer process and how to gain the most value".. Dr. Crosby and his team reached out to Abi Barrow and the MTTC staff to better understand the details of what was being asked of them by potential users of their research, how to evaluate their options for further development of the product, and how to make informed decisions about partnering and leveraging their breakthrough in adhesive ...
