Xenotransplantation. (1/119)

As transplantation waiting lists lengthen because of the shortage of donor organs, the death rates of patients continue to rise. Xenotransplantation offers the potential to solve the problem of organ shortage br providing an unlimited supply of healthy donor organs. However, there are several barriers to xenotransplantation, including graft rejection, potential xenozoonosis, physiologic incompatibilities and ethical concerns. Experimental xenotransplantation studies continue in several areas, ranging from tissue to whole- organ grafting. Clinical studies continue in the area of tissue xenotransplantation. Trials with extracorporeal xenografts in an acute setting to support fulminant organ failure are likely to begin in the near future. The reintroduction of whole-organ xenotransplantation must be based on sound scientific analysis with broad societal input so as to offer the maximal benefit to transplant recipients and their families.  (+info)

Long-term results of artificial anal sphincter implantation for severe anal incontinence. (2/119)

OBJECTIVE: To evaluate the long-term results of implantation of an artificial anal sphincter (AAS) for severe anal incontinence. SUMMARY BACKGROUND DATA: Implantation of an AAS is one of the options for treatment of anal incontinence when standard operations have failed. It is the only surgical option for treatment of anal incontinence in patients with neurologic disease that affects the pelvic floor and the muscles of the lower limb. METHODS: Seventeen patients underwent implantation of an AAS before 1993. These patients have been followed and their continence status evaluated. RESULTS: Two patients died of unrelated causes within the first 3 years after surgery, and in three patients the AAS was explanted because of infection. During the follow-up period, four patients had the AAS removed because of malfunction, and eight patients had a functioning AAS > or =5 years after the primary implantation. Five of these patients had revisional procedures, mainly because of technical problems in the early part of the study, when a urinary sphincter or slightly modified urinary sphincter was used. Continence at follow-up was good in four patients and acceptable in three, whereas one patient still had occasional leakage of solid stool. One patient had rectal emptying problems, which she managed by enema. CONCLUSIONS: An AAS based on the same principles as the artificial urinary sphincter seems to be a valid alternative in selected patients when standard surgical procedures have failed or are unsuitable. Approximately half of the patients have an adequate long-term result. Infectious complications still present a problem, whereas mechanical problems are less frequent with the modification of the device now available.  (+info)

A cell-based constitutive relation for bio-artificial tissues. (3/119)

By using a combination of continuum and statistical mechanics we derive an integral constitutive relation for bio-artificial tissue models consisting of a monodisperse population of cells in a uniform collagenous matrix. This constitutive relation quantitatively models the dependence of tissue stress on deformation history, and makes explicit the separate contribution of cells and matrix to the mechanical behavior of the composite tissue. Thus microscopic cell mechanical properties can be deduced via this theory from measurements of macroscopic tissue properties. A central feature of the constitutive relation is the appearance of "anisotropy tensors" that embody the effects of cell orientation on tissue mechanics. The theory assumes that the tissues are stable over the observation time, and does not in its present form allow for cell migration, reorientation, or internal remodeling. We have compared the predictions of the theory to uniaxial relaxation tests on fibroblast-populated collagen matrices (FPMs) and find that the experimental results generally support the theory and yield values of fibroblast contractile force and stiffness roughly an order of magnitude smaller than, and viscosity comparable to, the corresponding properties of active skeletal muscle. The method used here to derive the tissue constitutive equation permits more sophisticated cell models to be used in developing more accurate representations of tissue properties.  (+info)

Tissue engineering a blood vessel substitute: the role of biomechanics. (4/119)

The engineering of a functional blood vessel substitute has for a quarter of a century been a "holy grail" within the cardiovascular research community. Such a substitute must exhibit long term patency, and the critical issues in this area in many ways are influenced by biomechanics. One of the requirements is that it must be non-thrombogenic, which requires an "endothelial-like" inner lining. It also must have mechanical strength, i.e. a burst pressure, sufficient to operate at arterial pressures. Ideally, however, it must be more than this. It also must have viscoelastic properties that match those of the native vessel being replaced. Finally, if it is to be able to adapt to changing blood flow conditions, it must exhibit vasoactivity, a function which in and of itself can be viewed as biomechanical in nature. To achieve this requires having, as part of the construct, vascular smooth muscle cells, which are contractile in nature and oriented in a circumferential direction. Only if an engineered blood vessel substitute possesses all of these functional characteristics, can one say that the functionality exhibited by a native vessel is being mimicked.  (+info)

Artificial cornea: towards a synthetic onlay for correction of refractive error. (6/119)

Synthetic onlays that are implanted onto the surface of the cornea have the potential to become an alternative to spectacles and contact lenses for the correction of refractive error. A successful corneal onlay is dependent on development of a biocompatible polymer material that will maintain a healthy cornea after implantation and that will promote growth of corneal epithelial cells over the onlay, and development of a method for attachment of the onlay with minimal surgical invasiveness. The ideal onlay should be made of a material that is highly permeable yet has sufficient surface characteristics to stimulate stable and firm attachment of the corneal epithelium over the onlay. Recent research indicates that collagen I coated polymer materials that mimic the basement membrane of the corneal epithelium promote the most favorable growth of epithelial cells in vivo in comparison to wholly biological or synthetic materials.  (+info)

Chemical sensor based on nonlinearity: principle and application. (7/119)

Novel chemical sensors based on a time-dependent nonlinear response are reviewed. The strategy is to artificially mimic information transduction in living organisms. In taste and olfaction, information of chemical structure and concentration is transformed into nervous impulses in the nervous cell, i.e., time-dependent multi-dimensional information. Because the excitation and pulse generation in the nervous cell are typically nonlinear phenomena, it may be worthwhile to utilize the nonlinearity as the multi-dimensional information for molecular recognition. The principle of a "nonlinear" sensor is that a sinusoidal modulation is applied to a system, and the output signal is analyzed. The output signal of the sensor is characteristically deformed from the sinusoidal input depending on the chemical structure and concentration of the chemical stimuli. The characteristic nonlinear responses to chemical stimuli are discussed in relation to the kinetics of chemical compounds on the sensor surface. As a practical application, we introduced electrochemical sensors based on the differential capacitance, semiconductor gas sensors under the application of sinusoidal temperature or diffusion change, and a chemical sensor based on the spatio-temporal information. We demonstrated that mutli-dimensional information based on nonlinearity can provide quite useful information for the analysis of chemical species, even in the presence of another analyte or an interference with a single detector.  (+info)

Midkine, a heparin-binding growth factor, promotes growth and glycosaminoglycan synthesis of endothelial cells through its action on smooth muscle cells in an artificial blood vessel model. (8/119)

To study the interactions between smooth muscle cells and endothelial cells in vitro, we developed an artificial blood vessel model, which consisted of collagen gel containing human aortic smooth muscle cells and human umbilical vein endothelial cells grown on the gel. The blood vessel model was utilized to investigate the role of midkine, a heparin-binding growth factor, in the intercellular interactions that are important in angiogenesis. In the blood vessel model, midkine induced stratification of the endothelial cells and increased their proliferation and glycosaminoglycan synthesis. However, midkine had no effect on the smooth muscle cells or endothelial cells when they were cultured separately. Increased proliferation of the endothelial cells was also attained by coculturing them with smooth muscle cells in the presence of midkine or culturing endothelial cells with the conditioned medium of the smooth muscle cells, which had been treated with midkine. These experiments indicate that the target of midkine was smooth muscle cells, which secreted factor(s) acting on the endothelial cells. We identified interleukin-8 as one such factor; the synthesis of interleukin-8 by the smooth muscle cells was increased by exposure to midkine, and anti-interleukin-8 inhibited the midkine action. Furthermore, interleukin-8 caused stratification of the endothelial cells in the blood vessel model. These results provided evidence that midkine is one of the factors involved in epithelial-mesenchymal interactions.  (+info)

Purpose : The cornea efficiently restricts permeability of topically administered drugs into the eye. Currently, permeability of drug candidates is tested across excised animal corneas ex vivo or using in vitro cell culture models. The purpose of this study was to develop an artificial cornea for drug permeability screening in early drug development that more adequately resembles the human cornea. Methods : Several modifications of artificial corneas were prepared using different hydrogel cross-linking and coating techniques. The apparent permeability coefficient (Papp) values of standard reference molecules across artificial corneas were tested using Navicyte vertical diffusion chambers. Permeability characteristics (tightness, dynamic range) of the artificial cornea was assessed, and the Papp values across artificial cornea were correlated with those of ex vivo rabbit corneas and in vitro human corneal epithelial cell (HCE-T) culture model. HCE-T cells were also grown on top of artificial ...
PURPOSE OF REVIEW:. Artificial corneas are being developed to meet a shortage of donor corneas and to address cases in which allografting is contraindicated. A range of artificial corneas has been developed. Here we review several newer designs and especially those inspired by naturally occurring biomaterials found with the human body and elsewhere.. RECENT FINDINGS:. Recent trends in the development of artificial corneas indicate a move towards the use of materials derived from native sources including decellularized corneal tissue and tissue substitutes synthesized by corneal cells in vitro when grown either on their own or in conjunction with novel protein-based scaffolds. Biologically inspired materials are also being considered for implantation on their own with the view to promoting endogenous corneal tissue.. SUMMARY:. More recent attempts at making artificial corneas have taken a more nature-based or nature-inspired approach. Several will in the near future be likely to be available ...
The term perfusion is derived from the French verb perfuse meaning to pour over or through. Perfusionists employ artificial blood pumps to propel open-heart surgery patients blood through their body tissue, replacing the function of the heart while the cardiac surgeon operates.. When a patients blood is continuously removed and returned through plastic tubing to allow health care professionals to perform an artificial organ function on the blood, it is called extra-corporeal circulation (ECC) - outside the body blood circulation.. Presently there are many artificial organs that can be placed in an ECC to substitute for a patients failing organs. The list of artificial organs presently available for clinical use includes artificial hearts (blood pump), artificial lungs (oxygenator), artificial kidneys (hemodialysis), and artificial livers.. Perfusionists are capable of combining sterile tubing and artificial organs to build an ECC to meet the needs of several physician specialists to ...

Human recombinant collagen can be cross-linked with a variety of chemical cross-linking agents. Cross-linking methods can be tuned to confer collagen-based scaffolds with specific physical properties, improved antigenicity and thermal stability without impeding the ability of the material to integrate into the surrounding tissue and to promote regeneration. Here, we describe a method to cross-link human recombinant collagen using a water soluble carbodiimide. Carbodiimides are referred to as zero-length cross-linking agents as they are not incorporated into the final cross-link and thus pose minimal risk with respect to cytotoxicity. The resulting collagen-based scaffold possesses properties comparable to that of the human cornea and is thus suitable for use as a corneal substitute.. ...

Background. Stem cell therapy to improve cardiac function after myocardial infarction is hampered by poor cell retention, while it may also increase the risk of arrhythmias by providing an arrhythmogenic substrate. We previously showed that porcine adipose tissue-derived-stromal cells (pASC) induce conduction slowing through paracrine actions, whereas rat ASC (rASC) and human ASC (hASC) induce conduction slowing by direct coupling. We postulate that biomaterial microspheres mitigate the conduction slowing influence of pASC by interacting with paracrine signaling.. Aim. To investigate the modulation of ASC-loaded recombinant human collagen-based microspheres, on the electrophysiological behavior of neonatal rat ventricular myocytes (NRVM).. Method. Unipolar extracellular electrograms, derived from microelectrode arrays (8x8 electrodes) containing NRVM, co-cultured with ASC or ASC loaded microspheres, were used to determine conduction velocity (CV) and conduction heterogeneity.

Hmmm, the world of printers might seem to be rather boring to some as improvements in this area are hardly worth reporting on - rarely making headlines, so to speak. Well, printing has taken on a new dimension with the introduction of 3D printers, as you get to deliver what your mind has conceived in an actual, 3D object - which previously you had to spend far more money elsewhere to get that done.. Guess where is another use of 3D printer applicable in our everyday lives? Were talking about using a 3D printer to roll out artificial blood vessels, and these blood vessels might soon see action during transplants of lab-created organs.. It has been the major stumbling block until now in tissue engineering, as boffins had been scratching their heads as to how to supply artificial tissue with nutrients that require the use of capillary vessels to arrive. Why not provide artificial tissue with artificial blood vessels? Thats probably the route that a team at the Fraunhofer Institute in Germany ...
A bi-functional epoxy-based cross-linker, 1,4-Butanediol diglycidyl ether (BDDGE), was investigated in the fabrication of collagen based corneal substitutes. Two synthetic strategies were explored in the preparation of the cross-linked collagen scaffolds. The lysine residues of Type 1 porcine collagen were directly cross-linked using l,4-Butanediol diglycidyl ether (BDDGE) under basic conditions at pH 11. Alternatively, under conventional methodology, using both BDDGE and 1-Ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC)/N-hydroxysuccinimide (NHS) as cross-linkers, hydrogels were fabricated under acidic conditions. In this latter strategy, Cu(BF4)2·XH2O was used to catalyze the formation of secondary amine bonds. To date, we have demonstrated that both methods of chemical cross-linking improved the elasticity and tensile strength of the collagen implants. Differential scanning calorimetry and biocompatibility studies indicate comparable, and in some cases, enhanced properties compared to ...

Keratoprosthesis is a surgical procedure where a diseased cornea is replaced with an artificial cornea. Traditionally, keratoprosthesis is recommended after a person has had a failure of one or more donor corneal transplants. More recently, a less invasive, non-penetrating artificial cornea has been developed which can be used in more routine cases of corneal blindness. While conventional cornea transplant uses donor tissue for transplant, an artificial cornea is used in the Keratoprosthesis procedure. The surgery is performed to restore vision in patients suffering from severely damaged cornea due to congenital birth defects, infections, injuries and burns. Keratoprotheses are made of clear plastic with excellent tissue tolerance and optical properties. They vary in design, size and even the implantation techniques may differ across different treatment centers. The procedure is done by ophthalmologists, often on an outpatient basis. The idea of artificial cornea was first proposed in 1789 by ...
Corneal disease is the second most common cause of blindness in the word. It is estimated that 45 million people worldwide are bilaterally blind and 10 million are affected by corneal blindness. Corneal blindness mostly affects the population in the equatorial zone, due to the high exposure to UV light. Corneal grafting presents complications such as rejections and the lack of donor material and resources. Conventional cornea grafting (keratoplasty) is not advised for patients with bilateral corneal blindness or for those who suffer from a range of clinical problems including tear deficiency, chemical burns and uncontrollable intraocular pressure. At present, an artificial cornea, i.e. a keratoprosthesis (KRPO), is the only alternative to keratoplasty (corneal donor transplantation). Cornea implants consist of a clear optic part and a surrounding ring known as the skirt, which needs to integrate with the sclera of the eye. Currently used skirt materials lead to poor tissue integration, a major ...

A proposed solution to this problem is the idea of Encapsulated Cell Therapy (Galletti, 1995). It basically works as follows: The cells used can be either human or other animal cells. These cells are genetically altered to produce whatever it is that is needed in the body (insulin, other needed proteins, hormones, etc.). The cells are then protected from the immune system in a very clever capsule system made of a polymer material. This polymer has specially designed pores that are large enough to allow the desired excretion of therapeutic substances, but small enough to keep out the bodys immune system. In effect, we have a cybernetic system here, in which an isolated colony of foreign cells lives, protected, inside the humans system. This colony feeds off of the humans blood, and excretes its wastes and its specially designed products into the humans circulatory system.. There are other applications for this type of technology such as pain control systems and treatment of otherwise ...

Tissue engineering is an emerging field with the aim to produce artificial organs and tissues for transplant treatments. Cultivating cells on scaffolds by means of bioreactors is a critical step to forming the organ or tissue substitutes prior to transplantation. Among various bioreactors, the perfusion bioreactor is known for its enhanced convection through the cell-scaffold constructs. The enhanced convection will significantly increase the mass transport and at the same time, will increase the shear stress acting on the cells and scaffolds. To manipulate the scaffold-based cell culture process, knowledge of the mass transport and fluid flow (featured by flow velocity and shear stress) in bioreactors is required. Due to the complicated microstructure and multiphase flow involved in this process, the development of models for capturing the aforementioned knowledge has proven to be a challenging task. In this research, the mass transport and fluid flow in scaffolds cultivated in perfusion ...

In August 2009, the patient underwent penetrating keratoplasty with implantation of a Boston type II keratoprosthesis (through the eyelid) for extensive corneal and conjunctival cicatrization. Several months later, a fine retroprosthetic membrane had developed and was treated with YAG laser. The patient was then stable until September 2011, when he experienced acutely decreased vision and was found to have vitritis. He underwent a tap and inject procedure with antibiotics and an antifungal agent placed into the eye. The vision improved but a leak around the prosthetic device was identified, prompting a prosthetic replacement. The intraocular pressure was elevated post-operatively, and the patient ultimately underwent an Ahmed valve placement. After the valve was in place, the pressure remained well-controlled, but in January 2012, the patient developed a macula-off retinal detachment for which 1,000 cSt of silicone oil was placed during retinal detachment repair. Subsequently, a new ...
Purpose: Titanium (Ti) is an excellent implantable biomaterial that can be further enhanced by surface topography optimization. Despite numerous data from orthopedics and dentistry, the effect of Ti surface topography on ocular cells is still poorly understood. In light of the recent adaptation of Ti in the Boston Keratoprosthesis artificial cornea, we attempted to perform an extended evaluation of the effect of Ti surface topography on corneal cell adhesion, proliferation, cytotoxicity, transformation, and matrix deposition. Methods: Different surface topographies were generated on medical grade Ti-6Al-4V-ELI (extra-low interstitial), with linearly increased roughness (polished to grit blasted). Biological response was evaluated in vitro using human corneal limbal epithelial (HCLE) cells, stromal fibroblasts (HCF), and endothelial cells (HCEnC). Results: None of the Ti surface topographies caused cytotoxicity to any of the three corneal cell types. However, rough Ti surface inhibited HCLE and ...
I am currently researching for a fictional novel I wish to write. Part of the basis for this story revolves around a human trial study of an artificial blood that is stable at room temperature for extended periods, and substitutes for any blood type. A key point in the novel will be the ability of the blood substitute to cross the blood-brain barrier, and deposit in the brain where it will cause a reaction due to a set of circumstances. Right now I am considering making the blood on a sugar base, in order to pass into the brain, where it will react when endorphins reach a certain level (an unplanned effect). I am looking for information and comments as to the feasability of this idea, as well as specifics on artificial blood and the FDA requirements to get a drug to market. This is my first novel, and I am trying to keep all scientific aspects as real as possible. All assistance I recieve will be fully credited. If anyone can help, or point me in the right direction, it will be greatly ...
Provided are artificial muscle patches, which are adapted to be implanted adjacent a patients heart, and artificial sphincter cuffs, which are adapted to be implanted around a body lumen, such as the urethra, the anal canal, or the lower esophagus. The devices of the present invention comprise: (a) one or more electroactive polymer actuators; and (b) a control unit for electrically controlling the one or more electroactive polymer actuators to expand or contract the devices.
Meanwhile, a team led by Philippe Poulin at the University of Bordeaux used a wet-spinning technique-widely used to mass-manufacture polymer fibers-to create artificial muscles from polyvinyl alcohol and flakes of graphene oxide (Science 2019, DOI: 10.1126/science.aaw3722). The researchers heated the fiber to 100 °C, twisted it tightly, and then cooled it to room temperature to lock the material into its coiled structure. When the researchers heat this shape memory fiber again, it untwists to its original straight shape. Graphene oxide makes the fiber stiffer, stronger and tougher, so that it can be twisted more tightly and store more energy without breaking, enabling it to do more work as it untwists.. ...

A 60-year-old US grandmother, blind for nearly a decade, has recovered her sight after surgeons implanted a tooth in her eye as a base to hold a tiny plastic lens, her doctors said Wednesday. Sharron Kay Thornton, from the southern US state of Mississippi, lost her sight in 2000 when she came down with a case of Stevens-Johnson syndrome, a rare disease that scarred her cornea, according to the University of Miamis Bascom Palmer Eye Institute.. For patients whose bodies reject a transplanted or artificial cornea, this procedure implants the patients tooth in the eye to anchor a prosthetic lens and restore vision, said Thorntons surgeon Victor Perez.. In the procedure -- which was pioneered in Italy but was a first in the United States -- the medical team extracted Thorntons canine or eyetooth and surrounding bone, shaved and sculpted it, and drilled a hole into it to insert an optical cylinder lens.. We take sight for granted, not realizing that it can be lost at any moment, the ...
Global Retinal Implant Market is expected to reach USD 74.7 million by 2026. A retinal implant is also termed as the Argus® II retinal prosthesis system or bionic eye. These implantable devices are planned to supplant photo transduction within the eyes of persons with major retinal illnesses such as age-related macular degeneration or retinitis pigmentosa. The retinal implant market is estimated to grow at a CAGR of 10.6% over the forecast period as the scope and its applications are rising enormously across the globe.. The factors that are playing a major role in the growth of retinal implant market are rising occurrence of degenerative conditions, increasing disposable income in emerging countries, growing aging population, and development of enhanced and efficient technology. However, the high cost of research, lack of trained personnels, and development and lack of medical reimbursement are the factors that may restrain overall market growth in the years to come. Retinal implant ...
Researchers have developed a line immortal stem cells that allow them to generate an unlimited supply of artificial red blood cells on demand. If these artificial blood cells pass clinical trials, theyll be far more efficient for medical use than current red blood cell products, which have to be generated from donor blood - and would be a huge deal for patients with rare blood types, who often struggle to find matching blood donors. The idea isnt for these immortal stem cells to replace blood donation altogether - when it comes to regular blood transfusions, donated blood still does the trick.
Anti-thrombogenicity and endothelialization are two essential issues in devising blood-contacting medical implants, such as artificial blood vessels and vascular stents [1, 2]. Minimizing the plasma protein adsorption and platelet adhesion has proved beneficial in reducing thrombus formation especially in the initial implantation. Subsequently, rapid endothelialization of implant surfaces may significantly reduce the risk of long-term thrombogenesis and provide a fully hemocompatible interface. Furthermore, native endothelium has unique physiological role of maintaining vascular homeostasis, including the active anti-thrombosis, and the release of soluble factors that contribute to the inhibition of smooth muscle cell proliferation and hence reduce intimal hyperplasia [3, 4]. Rapid regeneration of endothelium is thereby crucial to the success of implantation. Numerous approaches such as natural polymer coating (collagen) [5], surface biomolecule immobilization (heparin) [6], and drug-eluting ...
Aortobifemoral bypass surgery is used to bypass diseased large blood vessels in the abdomen and groin.. To bypass a narrowed or blocked blood vessel, blood is redirected through a graft made of synthetic material (such as polytetrafluoroethylene [PTFE] or Dacron). This graft is sewn above and below the diseased artery so that blood flows through the graft. These man-made grafts are more likely to be used than transplanted natural grafts for aortobifemoral surgery, because the blood vessels involved are large.. The artificial blood vessel is formed into a Y shape. The single end of the Y is sewn on the aorta. The two split ends of the Y are sewn below the blocked or narrowed areas of the femoral arteries. This allows the blood to travel around (bypass) the diseased areas.. General anesthesia is used and will cause you to sleep through the procedure.. ...
This paper is about the quantitative prediction of the long term outcome of the endovascular coiling treatment of a patients cerebral aneurysm. It is generally believed that the local hemodynamic properties of the patients cerebral arteries are strongly influencing the origin and growth of aneurysms. We describe our approach: modelling the flow in a 3D Rotational Angiography (3DRA) reconstruction of the aneurysms including supplying and draining blood vessels, in combination with simulations and experiments of artificial blood vessel phantom constructs and measurements. The goal is to obtain insight in the observed phenomena to support the diagnostic decision process in order to predict the outcome of the intervention with possible simulation of the flow alternation due to the pertinent intervention ...

The US non-profit research company SRI International is testing a buoy-mounted, wave-powered generator in the ocean near Santa Cruz, California.. The wave-powered generator uses SRIs Electroactive Polymer Artificial Muscle (EPAM), a rubbery material that can generate electricity by simply being stretched and allowed to return to its original shape.. This artificial muscle can generate electricity directly from the motion of waves, with no need for complicated and costly hydraulic transmissions, typically found in other wave-power generators.. In 2004, the technology was licensed exclusively to Artificial Muscle, an SRI spin-off company. A Japanese company, Hyper Drive, has licensed the technology for wave-power generator applications from Artificial Muscle, and is sponsoring the testing of the device.. An earlier version of the generator was deployed in August 2007 in Tampa Bay, Florida. The Tampa Bay experiment used a generator design that was intended to show how the EPAM technology could ...

The major goal of this study was to evaluate the suitability of utilizing Survanta® as a dispersing agent for SWCNT to aid study of their bioactivity. The rationale behind its use include its simplicity and rapidity of nanoparticle dispersion (i.e., it is a single step process), biocompatibility (i.e., it has been approved for human clinical use), and commercial availability particularly as a sterile preparation which greatly facilitates in vivo and in vitro studies that require sterile conditions. In addition, one would argue that inhaled SWCNT would initially interact with alveolar lining fluid, which is modeled by Survanta® suspension. However, the effectiveness of this preparation in dispersing nanoparticles and its possible interfering effect on the bioactivities of SWCNT are not known, and, therefore, are investigated in the present study. The data presented demonstrate that Survanta® when used at the indicated concentrations is effective in dispersing SWCNT, yielding nanoparticles with ...

The patient returned in March of 2002. At this examination, his left eye BCVA was counting fingers at 4 feet. His left cornea was edematous and cloudy consistent with graft failure (Figure 1). IOP was approximately 5 mmHg (finger palpation) on 0.2% dorzolamide hydrochloride-0.5% timolol maleate ophthalmic solution twice daily. This time we agreed to perform keratoprosthesis implantation following detailed discussion regarding the risks and benefits. A Boston keratoprosthesis (KPro Type I) in a fresh donor corneal graft was implanted using standard technique.(7) The diameter of the donor corneal button was 8.5 mm, and the eye was trephined to 8.0 mm; anterior vitrectomy was also performed. At the end of the operation, 400 micrograms of dexamethasone was injected into the anterior chamber. A soft contact lens of 16.0 mm diameter and 9.8 mm base curve (Kontur Kontact Lens Co., Inc., Richmond, CA) was applied. No intraocular membrane formation was identified during the surgery. Histopathology of the ...
Efforts to create polymers that mimic the properties of biological muscle have come short of being practically useful. Often the bonding involved in making these polymers must be sufficiently strong to serve as actuators, but weak enough for reversible self-healing. Many models, to date, involve hydrogen bonding, but hydrogen bonds are sensitive to water. Li, et al. have, instead, exploited metal-ligand interactions as a way to mimic muscle properties.. The ligand 2,6-pyridinedicarboxamide (pdca)binds to Fe(III) via the pyridyl nitrogen and the nitrogen and oxygen on the carboxamides. Two pdca molecules coordinate to one Fe(III) atom through six coordination sites. Two of the sites are strong bonds (the pyridyl), two sites are medium strength bonds (the amides), and two are weak bonds (the carboxyl). Calculations of bond strength show that the strong bonds are similar to covalent bonds, while the weak Fe-O bonds are similar to hydrogen bonding. This multi-bonding structure, as it turns out, ...

Management of type 2 diabetes focuses on lifestyle interventions, lowering other cardiovascular risk factors, and maintaining blood glucose levels in the normal range.[25] Self-monitoring of blood glucose for people with newly diagnosed type 2 diabetes may be used in combination with education,[82] although the benefit of self-monitoring in those not using multi-dose insulin is questionable.[25] In those who do not want to measure blood levels, measuring urine levels may be done.[82] Managing other cardiovascular risk factors, such as hypertension, high cholesterol, and microalbuminuria, improves a person's life expectancy.[25] Decreasing the systolic blood pressure to less than 140 mmHg is associated with a lower risk of death and better outcomes.[83] Intensive blood pressure management (less than 130/80 mmHg) as opposed to standard blood pressure management (less than 140-160 mmHg systolic to 85-100 mmHg diastolic) results in a slight decrease in stroke risk but no effect on overall risk of ...
