Chronic inflammation and granuloma formation around irritating foreign bodies.
A malformation of the nervous system caused by failure of the anterior neuropore to close. Infants are born with intact spinal cords, cerebellums, and brainstems, but lack formation of neural structures above this level. The skull is only partially formed but the eyes are usually normal. This condition may be associated with folate deficiency. Affected infants are only capable of primitive (brain stem) reflexes and usually do not survive for more than two weeks.

Mice that lack the angiogenesis inhibitor, thrombospondin 2, mount an altered foreign body reaction characterized by increased vascularity. (1/314)

Disruption of the thrombospondin 2 gene (Thbs2) in mice results in a complex phenotype characterized chiefly by abnormalities in fibroblasts, connective tissues, and blood vessels. Consideration of this phenotype suggested to us that the foreign body reaction (FBR) might be altered in thrombospondin 2 (TSP2)-null mice. To investigate the participation of TSP2 in the FBR, polydimethylsiloxane (PDMS) and oxidized PDMS (ox-PDMS) disks were implanted in TSP2-null and control mice. Growth of TSP2-null and control skin fibroblasts in vitro also was evaluated on both types of disks. Normal fibroblasts grew as a monolayer on both surfaces, but attachment of the cells to ox-PDMS was weak and sensitive to movement. TSP2-null fibroblasts grew as aggregates on both surfaces, and their attachment was further compromised on ox-PDMS. After a 4-week implantation period, both types of PDMS elicited a similar FBR with a collagenous capsule in both TSP2-null and control mice. However, strikingly, the collagenous capsule that formed in TSP2-null mice was highly vascularized and thicker than that formed in normal mice. In addition, abnormally shaped collagen fibers were observed in capsules from mutant mice. These observations indicate that the presence or absence of an extracellular matrix component, TSP2, can influence the nature of the FBR, in particular its vascularity. The expression of TSP2 therefore could represent a molecular target for local inhibitory measures when vascularization of the tissue surrounding an implanted device is desired.  (+info)

Disruption of filamentous actin inhibits human macrophage fusion. (2/314)

The foreign body reaction to implanted biomaterials, characterized by the presence of macrophages and foreign body giant cells (FBGC), can result in structural and functional failure of the implant. Recently, we have shown that interleukin-4 and interleukin-13 can independently induce human macrophage fusion to form FBGC via a macrophage mannose receptor (MR) -mediated pathway. The MR is believed to mediate both endocytosis of glycoproteins and phagocytosis of microorganisms, which bear terminal mannose, fucose, N-acetylglucosamine, or glucose residues. Polarization of microfilaments to closely apposed macrophage membranes as observed with fluorescence confocal microscopy led us to ask whether MR-mediated fusion occurred via a filamentous actin-dependent pathway. Cytochalasins B and D and latrunculin-A, agents that disrupt microfilaments, inhibited macrophage fusion in a concentration-dependent manner. The concentrations of cytochalasins D and B that inhibited fusion did not significantly decrease macrophage adhesion, spreading, or motility but did inhibit internalization of Candida albicans during interleukin-13-enhanced, MR-mediated phagocytosis. Very low concentrations of cytochalasin B (< 2 microM) induced a slight enhancement of macrophage fusion. Taken together, the results of this study suggest that cytokine-induced, MR-mediated macrophage fusion requires an intact F-actin cytoskeleton and that the mechanism of fusion is similar to phagocytosis.--DeFife, K. M., Jenney, C. R., Colton, E., Anderson, J. M. Disruption of filamentous actin inhibits human macrophage fusion.  (+info)

Characterization of the importance of polysaccharide intercellular adhesin/hemagglutinin of Staphylococcus epidermidis in the pathogenesis of biomaterial-based infection in a mouse foreign body infection model. (3/314)

The production of biofilm is thought to be crucial in the pathogenesis of prosthetic-device infections caused by Staphylococcus epidermidis. An experimental animal model was used to assess the importance of biofilm production, which is mediated by polysaccharide intercellular adhesin/hemagglutinin (PIA/HA), in the pathogenesis of a biomaterial-based infection. Mice were inoculated along the length of a subcutaneously implanted intravenous catheter with either wild-type S. epidermidis 1457 or its isogenic PIA/HA-negative mutant. The wild-type strain was significantly more likely to cause a subcutaneous abscess than the mutant strain (P < 0.01) and was significantly less likely to be eradicated from the inoculation site by host defense (P < 0.05). In addition, the wild-type strain was found to adhere to the implanted catheters more abundantly than the PIA/HA-negative mutant (P < 0.05). The reliability of the adherence assay was assessed by scanning electron microscopy. To exclude contamination or spontaneous infection, bacterial strains recovered from the experimental animals were compared to inoculation strains by analysis of restriction fragment length polymorphism patterns by pulsed-field gel electrophoresis. In vitro binding of the wild-type strain and its isogenic mutant to a fibronectin-coated surface was similar. These results confirm the importance of biofilm production, mediated by PIA/HA, in the pathogenesis of S. epidermidis experimental foreign body infection.  (+info)

Plastic migration from implanted central venous access devices. (4/314)

BACKGROUND: This is the first reported study of histologically confirmed migration from intravenous access devices in children. METHODS: The capsules from around intravenous access devices were examined by light microscopy to determine the extent of the foreign body response; energy dispersive x ray analysis was performed to document the elemental content of the foreign material. RESULTS: A fibroconnective tissue capsule was found around all the samples. Elemental silicon was found in six of 13 tissue samples, and a foreign body giant cell reaction was seen in three of these. CONCLUSIONS: The pseudocapsule that surrounds an implanted vascular access device often has residual foreign material, including silicone.  (+info)

Symptomatic Rathke's cleft cyst coexisting with central diabetes insipidus and hypophysitis: case report. (5/314)

We describe a 48-year-old female with acute onset of central diabetes insipidus followed by mild anterior pituitary dysfunction. Magnetic resonance imaging (MRI) revealed enlargement of the hypophysis-infundibulum accompanied by a cystic component. She underwent a transsphenoidal exploration of the sella turcica. Histological examination showed foreign body type xanthogranulomatous inflammation in the neurohypophysis which might have been caused by rupture of a Rathke's cleft cyst. The MRI abnormalities and anterior pituitary dysfunction improved after a short course of corticosteroid administration, but the diabetes insipidus persisted. The histological findings in this case indicated the site of RCC rupture and the direction of the progression of RCC induced neurohypophysitis and adenohypophysitis.  (+info)

Efficacy of trisacryl gelatin microspheres versus polyvinyl alcohol particles in the preoperative embolization of meningiomas. (6/314)

BACKGROUND AND PURPOSE: Trisacryl gelatin microspheres are a new, commercially available nonabsorbable embolic agent. The purpose of this study was to evaluate their efficacy in the preoperative embolization of meningiomas as compared with polyvinyl alcohol (PVA) particles of various sizes. METHODS: In 30 consecutive patients, trisacryl gelatin microspheres (150-300 microm) were used for the preoperative superselective embolization of meningiomas (group 1). Thirty other consecutive patients had embolization with PVA particles of 45 to 150 microm (n = 15, group 2) and of 150 to 250 microm (n = 15, group 3). Extent of devascularization, intraoperative blood loss, blood transfusion, and hemostasis at the time of surgery were recorded for every patient. The inflammatory reaction, the extent of necrotic areas, and the most distal intravascular location of the embolic agent (arterial, arteriolar, precapillary, capillary) were recorded. RESULTS: There was no significant difference in the extent of angiographic devascularization among the groups. Intraoperative blood loss differed significantly between groups 1 and 2 and groups 1 and 3, but not between groups 2 and 3. The trisacryl gelatin microspheres were located more distally in tumor vessels than were the PVA particles of either size. The extent of intratumoral necrosis was not significantly different between the two embolic agents. In all groups there was a mild inflammatory tissue reaction in the vicinity of the embolic agent. CONCLUSION: Trisacryl gelatin microspheres may be effective in the preoperative embolization of meningiomas, producing significantly less blood loss at surgery than seen with PVA particles of either size, possibly because of the significantly more distal vascular penetration of the microspheres.  (+info)

Interferon-gamma protects against biomaterial-associated Staphylococcus epidermidis infection in mice. (8/314)

Survival of Staphylococcus epidermidis inside macrophages has been recognized as a pivotal process in the pathogenesis of biomaterial-associated infection (BAI). Interferon (IFN)-gamma is a potent activator of macrophages. This study examined whether subcutaneous injections of IFN-gamma can reverse macrophage deactivation induced by implanted biomaterials. Mice received subcutaneous implants combined with an injection of 106 S. epidermidis to induce an experimental BAI. Subsequently, 3 groups of mice received subcutaneous injections of 25,000 IU IFN-gamma 3 times weekly, 10,000 IU IFN-gamma 3 times in 2 weeks, or saline 3 times weekly (saline control), respectively. A fourth group received no injections (control). Segments and tissues of the IFN-gamma-treated mice were significantly less (P<.05) culture positive than those of the control groups. Histologically, the high numbers of intracellularly persisting gram-positive cocci observed in the control mice were absent in the IFN-gamma-treated mice. These data indicate that IFN-gamma protects against experimental BAI.  (+info)

Finally, on a more speculative note, we would like briefly to discuss why there is evidently a physiologic mechanism that enables inflammatory cells to recognize the partially denatured fibrinogen that accumulates on implant surfaces. Fibrin and fibrinogen degradation products, but not soluble fibrinogen, are known to participate in many situations that lead to inflammation and/or phagocyte recruitment. These include delayed-type hypersensitivity reactions, trauma, fibrosis, the reaction to many different types of solid tumors, and wound-healing reactions (49-58). It follows that surface-immobilized fibrinogen may resemble fibrin or fibrin degradation products. Fibrinolysis and fibrin degradation products are probably not involved in biomaterial-mediated inflammatory responses, because the powerful protease inhibitor, Trasylol, has no effect in vivo on the extent of acute inflammatory responses to biomaterial implants (59). Rather, the denatured fibrinogen bound to biomaterial implants may ...

Bacterial infections on the surface of medical devices are a significant problem in therapeutic approach, especially when implants are used in the living. In cardiology, pacemaker generator pocket surfaces, made in titanium alloy can be colonized by pathogen microorganism. This contamination represents a major risk of sepsis, endocarditis and localized infections for patients. A way to limit this bacterial contamination is to modify the surface topography using nano-structuration process of the titanium alloy surface of the implanted devices. The aim of this study is to evaluate the influence of TiO2 nanotube layers on bacterial infection in the living, considering the feasibility of an animal model of chronic foreign body infection. TiO2 nanotube layers prepared by electrochemical anodization of Ti foil in 0.4 wt% hydrofluoric acid solution were implanted subcutaneously in Wistar rats. Three weeks after implantation, TiO2 implants were contaminated by a Staphylococcus epidermilis strain using two
Clinical evaluations and diagnosis of foreign body reactions pose a challenge as they depend on the type of foreign body involved, the duration of its presence, symptoms associated and the clinical picture.. A careful evaluation of the radiographs is essential as the foreign bodies have different radiodensities, sizes and shapes. Their appearance is influenced by a number of factors which include its power to attenuate the x-ray beam which determine its radiodensity, superimposition of these objects with the anatomic hard tissue structures and the exposure parameters. 10 Any materialistic substance which is not naïve to the human body is a foreign object and will evoke an immune response as a foreign body reaction resulting in a granuloma formation. There are circumstances in which the substances that provoke the acute inflammatory reaction are particulate and larger than the phagocytes and could not be digested by the reacting neutrophils causing a response namely granulomatous inflammation. ...
To reinforce the abdominal wall with mesh material is the gold standard in hernia repair and has lead to a considerable reduction of recurrence rates, however their implantation is associated with acute and chronic side effects like seroma and as long-term complication in particular chronic pain [13, 14, 21-24]. In particular long-term complications are supposed to be the consequence of a foreign body reaction (FBR), which is induced by every implantation of non-absorbable polymeric mesh material [25, 26]. FBR offers characteristics of a chronic inflammatory reaction, which is marked by an activation of cytokine cascades and proteases, such as the matrix metalloproteinases 2 (MMP-2) [27, 28]. This well known continuous expression of MMP-2 in foreign body reaction can also be observed in our study (Figure 1) whereas MMP-2 expression after injury is normally restricted to the proliferative phase of wound healing.. For this reason the inhibition of inflammation and as a consequence the ...

Under ideal conditions, implants should initiate the desired host response. Ideally, the implant should not cause any undesired reaction from neighboring or distant tissues. However, the interaction between the implant and the tissue surrounding the implant can lead to complications.[1] The process of implantation of medical devices is subjected to the same complications that other invasive medical procedures can have during or after surgery. Common complications include infection, inflammation, and pain. Other complications that can occur include risk of rejection from implant-induced coagulation and allergic foreign body response. Depending on the type of implant, the complications may vary.[1] When the site of an implant becomes infected during or after surgery, the surrounding tissue becomes infected by microorganisms. Three main categories of infection can occur after operation. Superficial immediate infections are caused by organisms that commonly grow near or on skin. The infection ...
Diabetes, cancer, heart disease… each of these deadly problems involves chronic inflammation.. Before looking at the foods that fight it, it is good to know what it is in the first place. Why do we get inflammation? What good is it?. There are five qualities of inflammation. They are pain, swelling, redness, heat and loss of function. These are your bodys response to injury or trauma. For instance, if you get a cut, the area around the cut becomes swollen, painful, warm and red. It is also often hard to use. Your body protects itself. It rushes healing to the injury.. This is also the bodys response to germs. The germ is the cause. The inflammation is your bodys response to fight it.. For acute trauma and infection, inflammation is a very good thing indeed. It speeds healing and helps prevent further problems.. What about chronic inflammation?. In some ways it is different than the acute form. But it is still your body making an effort to heal. It shows up in diabetes, allergies, immune ...

The grinding and abrading of metal joint components releases tiny metal molecules that begin a foreign body reaction and cause dangerously elevated metal levels in the body. Metallosis occurs with titanium-based joint implants as well as those made with chromium and cobalt although the toxicity of these metals varies. When the body detects metal particles, the immune system goes into overdrive causing inflammation, swelling and other painful conditions. In the joints, metallosis causes synovitis, which is the inflammation of the synovial tissue and membranes that line the joints. Synovitis is a painful condition associated with gout that causes unbearable pain and makes joint movement difficult due to swelling and increased pressure.. ...

The team, led by Dr Simon Johnston from the Universitys Department of Infection, Immunity and Cardiovascular Disease, found that fungi which are not able to make these signals were less able to grow during infection.. Dr Johnston, Senior Research Fellow in Infectious Disease, said: Weve discovered that these immune signals - fungal prostaglandins - deactivate immune cells, preventing them from destroying the infection.. We found the fungus was activating a normal immune pathway that prevents overstimulation of the immune system, but is essential in stopping infections.. Opportunistic infections like Cryptococcus - which normally pose no threat, but are potentially life-threatening in those with weakened immune systems - are an increasing problem and are often very difficult to treat.. Understanding how opportunistic infections ...
A cell is not a sack of water. Its a thick as a gelatin, and the total number of large molecules in a cell can correspond to up to 40 percent of its total volume. This means that proteins have less room to fold an function in, explains Pernilla Wittung-Stafshede. The crowdedness of a cell thus entails that the form and function of proteins can be affected. This means in such cases that it if it was possible to modulate the congestion in the cell, it could constitute a precision tool for manipulating the shape of a protein. What other proteins might have different functions if we crunched them together? With such a tool, we might be able to turn specific activities and signals on or off in proteins. We speculate that this could be used in the future to affect the course of various diseases, for example, she explains. The study is the first to show that crowdedness in the cell can entail shape changes in a large, biologically relevant protein. The studies were carried out with the aid of ...
When anaerobic exercise is being done regularly the body will adapt itself to cope with lactic acid better, during anaerobic exercise the body needs to create energy without using oxygen, however when it does it creates lactic acid which will cause discomfort and at times will cause the exercise to stop. The body will adapt itself because when these sorts of exercise are going it stimulates the muscles which once they are stimulated several times will be able to cope with the discomfort more, the body will also become better at getting rid of the lactic acid quicker as it when long term exercise occurs the chronic response of the body will be to increase the lactic acid threshold. someone who trained regularly using the lactic acid acid will be able to tolerate lactic acid better as their body will be better at disposing it and will be more used to the feeling. this means that a athlete wouldnt fatigue as quickly because lactic acid is the main cause of fatigue of the muscles. The capillary ...

With modern-day living, people constantly stimulate this system, which is most definitely not how this system was designed to be used. This constant triggering causes problems that can lead to even bigger problems.. When youre under chronic stress, you force your body to adapt to whatever the crisis situation is. The physiological stress expresses itself in many ways. When youre fasting, your body has even more difficulty dealing with stressors, because you ideally want your body to be working at cleansing your cells and burning fat and not dealing with other challenges.. Here are some of the symptoms of chronic stress adaptation: ...

By Muzamil Arif Stress can be defined as any type of change that causes physical, emotional, or psychological strain. Stress is your bodys response to anything that requires attention or action. Stress is a feeling of emotional or physical tension. It can come from any event or thought that makes you feel frustrated, angry, or nervous. Stress is your bodys reaction to a challenge or demand. In short bursts, stress can be positive, such as when it helps you avoid danger or meet a deadline. Stress is a very common problem being faced today. Every individual will experience stress in one or the other time. Not all types of stress are harmful or even negative. Some of the different types of stress that you might experience include: Acute stress: Acute stress is a very short-term type of stress that can either be positive or more distressing; this is the type of stress we most often encounter in day-to-day life. Common causes of acute stress include noise, danger, crowding, or isolation. Chronic
The cardiovascular system delivers oxygen, hormones, nutrients, and white blood cells throughout the body by circulating blood. The heart, a fist-sized series of muscles that is nothing more than a pump, powers everything. As we alerted you in the previous chapter, just like any mechanical device, the heart has a finite lifespan-80 years, more or less, which is pretty good for any pump. Depending on how hard and how fast it is required to run, under what conditions it is forced to operate, and how it is cared for, it can last significantly shorter or longer than its advertised specifications. Unlike most other pumps, the heart is subject to both automatic and manual operation. It can be speeded up or slowed down at will, just by thinking about an image of a South Pacific beach, an impending deadline, or an attractive classmate. The heart is also capable of independent action as it continues to beat steadily, thumping away when you are awake or asleep.. As you learned earlier, one immediate ...

Dr. Hooper and her colleagues showed for the first time how the protein works to police the intestinal demilitarized zone, preventing the naturally occurring bacteria from invading the wall of the intestine, where they can cause problems such as IBD.. If too many bacteria invade this demilitarized zone, you get ramped up production of the protein RegIIIγ and it pushes them back, Dr. Hooper said. In people with IBD - in which inflammation and the bodys response to it can result in painful ulcers and bloody diarrhea - the demilitarized zone is compromised and more bacteria come in contact with the intestinal lining, she explained.. Dr. Hoopers four-year study, which compared the intestinal health of mice that lacked the protein with that of normal mice, found that mice lacking the protein also lacked the protected space between the bacteria and the intestinal lining.. The researchers have patented RegIIIγ as a potential antibiotic therapeutic, though further study is needed to determine if ...

Sprinting is a cycle of repeatedly falling and catching yourself. Let me make this very, very clear: there is no pushing off in a sprint. Gravity is the propelling force when running... yes, even your precious jogging. Even when you are walking, the only thing that is keeping you moving is gravity, reactive forces, and your bodies response to these forces. Think I am full of shit? Stand up right now. As tall as you can with your hips, knees, and shoulders locked completely out. Now, try to take a step forward without LEANING into it first. If a push off actually existed, you should just be able to start moving without any assistance from gravity. This is simply impossible. Even when competitive Olympic sprinters start with their feet in the blocks, there is no push off. There is only a concentric action of the hip flexor complex in order to catch the body off the blocks. Those blocks enable sprinters to begin falling before they start running. This way, they can pretty much start in the most ...

It appears to me that much of what we do, think etc can be shown by fMRI to change the brain. No matter what method you use (brain retraining techniques, medication, vitamins, surgery that reduce local symptoms etc) a change is produced in the body. This change produces (as I understand it) a change in the brain. Isnt it true that as change affects the brain, then at the time of an inciting event that the brain would change. I believe it is time we stopped measuring the change and just conclude that change in the brain is a fact. This is an exciting development in my opinion as it would seem that we are able to effect beneficial changes to our well being by doing, thinking etc things that we now know to produce beneficial brain changes. This change can also be produced, I think, by many means, such as physical exercises, thought training, meditation, taking medicine, immuno suppressants, vitamins etc. I suspect anything that elicits a body response may be shown to change the brain. ...

In this article, well show you how to distinguish real work stress from imaginary stress using five surefire signs.Abbott *, an international company that has been researching and manufacturing drugs since 1900, helped us in preparing the material. It may seem strange, but in science there is no single and generally accepted definition of stress. It is often said that stress is the bodys response to irritating stimuli, and in a broad sense, it is generally a reaction to novelty. At the same time, the body needs some level of stress in order to maintain a comfortable psychological state. This can be seen from the so-called stress curve - it shows where the well-known comfort zone begins and ends.If the stress level is too high, the body has to overcome it, be it a human or a grape snail. Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383502/. It is customary to distinguish two forms of stress management. The first is to improve predictability by changing the environment.

A. Evidence for carcinogenicity to humans (inadequate). An early report was made of a woman who had developed an undifferentiated soft-tissue sarcoma following multiple injections of iron-dextran complex [ref: 1]. In a report on 196 cases of sarcoma of the buttock, four of 90 for whom records on drug use were still available had been given intramuscular injections of iron. In three of the cases, an interval of at least two years had elapsed [ref: 2]. A selective tendency to report receiving iron injections may have introduced bias. A review of reports during the period 1960-1977 indicated that nine malignancies had been described in five reports. Two were thought to have been foreign-body reactions to fat necrosis; one was a metastatic carcinoma at the site of an iron-dextran injection; and one was a reticulum-cell sarcoma with fractures of the pelvis possibly only coincidentally related to iron injections six years before. Several of the remainder were of different histological type [ref: 3]. ...

Macrophages are the dominant infiltrating cells that respond rapidly to biomaterial implantation in soft and hard tissues. These cells and their fused morphologic variants, multinucleated giant cells or foreign body giant cells, usually remain at biomaterial-tissue interfaces for the lifetime of the device in vivo. As a component of the immune system, macrophage activities are closely related to immune responses, inflammation and foreign body responses. However, macrophages also mediate biodegradation of bioresorbable materials via phagocytosis and extracellular degradation. In addition, macrophages are essential for effective tissue regeneration as they regulate the recruitment, proliferation and differentiation of target cells, such as fibroblasts, osteoblasts, endothelial cells and keratinocytes during healing processes.
TY - JOUR. T1 - Pharmacokinetics and PK-PD modelling of danofloxacin in camel serum and tissue cage fluids. AU - Shojaee Aliabadi, F.. AU - Ali, Badrelin H.. AU - Landoni, M. F.. AU - Lees, P.. PY - 2003/3. Y1 - 2003/3. N2 - The pharmacokinetics and pharmacodynamics of danofloxacin were studied in the camel in a two period cross-over study. After intravenous (i.v.) administration at a dose rate of 1.25 mg/kg, the pharmacokinetics of danofloxacin indicated a high volume of distribution (V darea=3.43 L/kg), relatively rapid clearance (0.44 L/kg/h) and half-life of 5.37 h. After intramuscular (i.m.) dosing absorption was complete (F=114.5) and rapid (T (1/2)abs=0.12 h) and terminal half-life was 5.71 h. Danofloxacin penetrated fairly slowly into both inflamed (exudate) and non-inflamed (transudate) tissue cage fluids and was cleared slowly from these fluids, elimination half-life being at least twice that for serum for both exudate and transudate after both i.v. and i.m. dosing. The antibacterial ...
Polypropylene meshes that are commonly used for inguinal hernia repair may trigger granulomatous foreign body reactions. Here, we show that asymptomatic patients display mesh-associated inflammatory granulomas long after surgery, which are dominated by monocyte-derived macrophages expressing high levels of inflammatory activation markers. In mice, mesh implantation by the onlay technique induced rapid and strong myeloid cell accumulation, without substantial attenuation for up to 90 days. Myeloid cells segregated into distinct macrophage subsets with separate spatial distribution, activation profiles, and functional properties, showing a stable inflammatory phenotype in the tissue surrounding the biomaterial and a mixed, wound-healing phenotype in the surrounding stromal tissue. Protein mass spectrometry confirmed the inflammatory nature of the foreign body reaction, as characterized by cytokines, complement activation, and matrix-modulating factors. Moreover, immunoglobulin deposition increased ...

Cardiovascular disease is one of the leading causes for morbidity and mortality in the developed countries. Cardiac tissue engineering is a promising novel approach in the regenerative medicine field aimed to provide a reparative solution for the damaged myocardium and restore heart function. However, functional donor-to-host integration of the engineered tissue constructs remains a critical challenge. The overall objective of this work is to design an optimal delivery system for cells and growth factors for cardiac treatment, taking into account several parameters for better integration of the engineered construct within the host tissues, including a preferable mode of implantation, superior pro-angiogenic properties and reduced foreign body response. In this context, we developed MRI/fluorescence bi-modal imaging to document the integration of the hydrogel implants in vivo in a non-invasive and continuous manner. We focused on the characterization of the scaffolds dissolution, resorption and ...

Functional artificial vascular meshes from biodegradable polymers have been widely explored for certain tissue engineered meshes. Still, the foreign body reaction and limitation in endothelialization are challenges for such devices. Here, degradable meshes from phase-segregated multiblock copolymers consisting of poly(ε-caprolactone) (PCL) and polydepsipeptide segments are successfully prepared by electrospinning and electrospraying techniques. The pEGFP-ZNF580 plasmid microparticles (MPs-pZNF580) were loaded into the electrospun meshes to enhance endothelialization. These functional meshes were evaluated in vitro and in vivo. The adhesion and proliferation of endothelial cells on the meshes were enhanced in loaded mesh groups. Moreover, the hemocompatibility and the tissue response of the meshes were further tested. The complete tests showed that the vascular meshes modified with MPs-pZNF580 possessed satisfactory performance with an average fiber diameter of 550 ± 160 nm, tensile strength of 27 ± 3
To decouple the extracellular oxidative toxicity of catechol adhesive moiety from its intracellular non-oxidative toxicity, dopamine was chemically bound to a non-degradable polyacrylamide hydrogel through photo-initiated polymerization of dopamine methacrylamide (DMA) with acrylamide monomers. Network-bound dopamine released cytotoxic levels of H2O2 when its catechol side chain oxidized to quinone. Introduction of catalase at a concentration as low as 7.5 U/mL counteracted the cytotoxic effect of H2O2 and enhanced the viability and proliferation rate of fibroblasts. These results indicated that H2O2 generation is one of the main contributors to the cytotoxicity of dopamine in culture. Additionally, catalase is a potentially useful supplement to suppress the elevated oxidative stress found in typical culture conditions and can more accurately evaluate the biocompatibility of mussel-mimetic biomaterials. The release of H2O2 also induced a higher foreign body reaction to catechol-modified hydrogel ...
The radially expandable prosthesis for implantation in a lumen comprises a tubular wall produced from sheet metal and showing cuts enabling the prosthesis to expand. By using water guided laser cutting technology to make these cuts and/or specific electrochemical polishing technology a more biocompatible prosthesis is obtained, causing less thrombogenicity and less foreign body reaction. By covering an intraluminal prosthesis with a titaniumnitride coating the biocompatibility of the prosthesis is improved. By applying perforating or non-perforating holes (4) and filling these holes with a therapeutic agent, the intraluminal prosthesis can be used to locally administer medicines, genes and or other substances to prevent in this way thrombotic occlusions and/or neointimal hyperplasia and prosthesis narrowing. Using this specific perforated prosthesis design the total drug capacity can be increased and also the drug release time prolongs significantly.
Both divinyl benzene copolymer (plastic) beads and schistosome eggs produce inflammatory reactions after intravenous deposition into the lung of a mouse. As reported previously, the schistosome egg granuloma is an immunologic reaction of the delayed hypersensitivity type; this inflammatory process is prevented by immunosuppressive measures, and characteristically demonstrates an anamnestic response. In contradistinction, the plastic bead granuloma appears to be characteristic of a foreign body reaction; it is unaffected by immunosuppressive measures and does not demonstrate an anamnestic response with repeated exposure. The data in this report suggest that the granuloma formation around plastic beads is a nonimmunologic reaction induced by chemical mediators of inflammation. This proposal is supported by the following findings: the plastic beads activate Hageman factor in normal human and mouse plasma; the plastic beads induce vascular permeability-enhancing activity as measured in guinea pig ...
Fibrin has been found to have many promising applications within the medical field, such as enhancing the endothelialization of peripheral vascular grafts in vitro [18]and promoting operative hemostasis during cardiovascular surgery [19-21]. Studies in the porcine coronary model indicate that native fibrin is deposited at the site of arterial injury and, in part, determines the neointimal response [5, 10]. This evidence prompted the first study assessing the response of the arterial wall to fibrin-coated stents [12].. Using the same porcine coronary model, 34 such stents were placed in 20 animals with no acute complications. Follow-up angiography at 28 days confirmed patency in all 31 remaining stented coronary segments. In all cases the fibrin was still structurally intact and completely endothelialized. Importantly, there was no exaggerated neointimal response or foreign body reaction to the fibrin stent, and local vascular integrity was maintained.. The use of autologous vein grafts to ...

Medical nanorobots on cytotherapeutic missions will often need to enter the living cell to perform repairs. Such missions may require the participation of many cooperating nanorobots, or perhaps just a few but relatively large nanorobots, per cell. And so the question logically arises: How many nanorobots can safely be crammed into a single living cell? There are at least two issues here. First, how much new foreign material can be added to a cell? Second, how much of a cells existing volume can be replaced with foreign material with no change in total cell volume? Since we cant yet do direct experiments with medical nanorobots and living cells, no precise answer is possible. But we can estimate the maximum volume of foreign material that the intracellular compartment might safely accommodate by examining analogous instances of cellular intrusion.. We can start by considering cell membrane elasticity. How much can the cellular membrane stretch before it breaks? The introduction of foreign ...

Inflammation is a series of biochemical and cellular events that constitute our bodys response to infection. Inflammatory cells surround invading pathogens and generate highly reactive and toxic chemicals including Clorox (sodium hypochlorite) and chlorine gas. They also synthesize antibodies to help clear bacteria, viruses, and other noxious stimuli, and they produce a range of signaling molecules such as prostaglandins and cytokines to amplify the inflammatory response.. This vigorous attack causes some collateral damage to surrounding tissue but normally it is local and transient. However, prolonged exposure to inflammatory stimuli or incorrect regulation of the inflammatory response leads to chronic and occasionally systemic tissue damage. As outlined elsewhere in this issue, this contributes to many important human diseases.. There is a rich history of research on the cause and treatment of inflammation, which illustrates the role that trained observation, serendipity, initiative, and hard ...

Feeding mice a high fat diet for several months causes inflammation in many tissues of the body, particularly fatty tissues (adipose tissues) in the abdomen, skeletal muscles, and liver. White blood cells migrate into these tissues and release proteins that change the normal functions of these tissues, thereby contributing to the development of type II diabetes. There are many different types of white blood cells, and our work has been to define the specific types that migrate into the tissues, and define the role these cells play in causing type II diabetes. In this study we analyzed one type of white blood cell called alpha beta T cells, and analyzed their influence in obesity-induced inflammation of skeletal muscle, a major organ that takes up glucose from the blood. In this study we wanted to evaluate the effect of alpha beta T cells on the bodys response to insulin, and their role in causing inflammation of adipose tissue and skeletal muscle as the mice become obese. We found that both ...

Pharmacogenetics, Kinetics, and Dynamics for Personalized Medicine provides a primer to understand pharmacogenetics (the study of genetic factors that influence how a drug works) in the applied context of pharmacokinetics (how the body handles a drug) and pharmacodynamics (the effects of a drug on the body). This valuable foundation illuminates how these principles and scientific advances can create optimal individual patient care, that is, personalized medicine. Through specific drug examples, this resource explores how the genetic constitution of an individual may lead to the need for an altered dose or in some cases alternative drug therapy. Real-world cases highlight the specific relationships between genetics, drug action, and the bodys response as well as adverse drug reactions, altered metabolism, and drug efficacy. Ethical issues concerning pharmacogenomics and study design are also discussed in this concise overview ...
Health & Wellness column: - We all age, but the deterioration associated with aging (called, senescence) is partly under our control. Senescence is speeded up by toxicity and our bodies response to it. The human body has many natural defenses against environmental toxicity. These include the constant shedding of the skin and the lining of the gastrointestinal tract, which slowly dispels environmental and intestinal toxins from the body; the activity of protective immune responses which limit the attachment of toxins to the surfaces of the lungs or the gastrointestinal tract; enzyme systems in the liver which destroy toxins and prepare them for excretion in the bile or the urine; enzymes which repair damaged cells and promote healing. In this column, Detoxification: The Key to Longevity, Dr. Galland discusses strategies for limiting free-radical induced damage through dietary antioxidants which help to bolster the bodys defense system, including vitamins, minerals, bioflavonoids and carotenoids.
Mast cells are unique cells of the immune system that are involved in the bodys response to inflammation and allergies.

Press Release issued Dec 22, 2014: One of the major breakthroughs that genetic testing has paved way for includes Personalized Medicine. Personalized medicine is the use of new methods of molecular analysis for better management of a patients disease or predisposition towards a disease. PGx, the study of variations of DNA and RNA characteristics as related to drug response, is one of the most exciting areas of personalized medicine today. Patients typically have variability in response to many drugs that are currently available. PGx seeks to understand how differences in genes and their expression affect the bodys response to medications. Such approaches promise the advent of Personalized Medicine in which drugs and drug combinations are optimized for each individuals unique genetic makeup.
Herb Lax - Do you need it?. You be the Judge!. It has been known by the natural healing profession for many years, and is recently being validated by medical physicans and surgeons, that well over 90% of degenerative disease conditions can be related directly to intestinal stasis-that is, a stagnant, fermenting condition within the bowels and related organs. This problem doesnt necessarily correspond to actual known constipation. A person can move his bowels many times a day and still be encumbered with decaying food materials, chemicals, parasites, mucus and dead cells, all of which contribute to the circulation and re-circulation of toxins throughout the whole body giving rise to an endless chain of di-sease conditions.. When Energizing Soy Protein and Vita Lea or the RX for Healthy Living are introduced to a new person for the first time the bodys response to the nutrition program is to start releasing stored toxins from the cells, and this process puts more stress on the organs of ...
Other observations about some subtle messaging we may be receiving in efforts to mitigate the harmful effects of exposure to radiation contamination (just postulating, no proof here…): Yesterdays Science/Health news reported on yet another study showing the definite harmful effects of eating red meat, saying it causes cancer and heart disease and cuts ones life short AND an article about the myths the many healthful benefits of milk being just that, myth.. Given the fact that isotopes like cesium bio accumulate in cows milk would mean it is also bioaccumulating in cows and cattle…our red meat. So…despite the scientists reporting meats harmful health effects are due to cholesterol and fat build up in our bodies, perhaps these things are happening because it is our bodies response to the radiation possibly present in the meat? Anyone else ever considered this? I saw one doctor in a video describe that salt had a corrosive effect on our arteries, so the cholesterol build up was actually ...
WHAT RESEARCH SHOWS ABOUT STRESS AND ILLNESS Traditional medicine views illness through the eyes of Newton. The cause of our problems is outside of us. Everything from genes to bacteria, the foods we eat, the weather, and aging are the cause of our problems. It is hard to accept the idea that the mind is at the source of illness but the evidence clearly shows that it is true. As early as 1983 Eric Kandel, M.D. showed that thoughts have the power to turn genes on and off. In 2000 he was awarded the Nobel Prize for this discovery. His discovery has revolutionized the field of brain rehabilitation. More recently, Candace Pert (1996) demonstrated the bodys response to our perception of our selves and our circumstances. Her work details the chemicals released into the bloodstream in response to various stressors. It leaves little room for doubt that the mind influences the body. The chemicals released when we are stressed influence organs including the pituitary, adrenals, thyroid, pancreas, and ...
Because of the autonomic nature of our bodys response, sometimes people can be unaware that they are experiencing a stress response. After all, we release stress hormones when there is a lack of sleep or when we are pressed for time. Being overworked, annoyed, or constantly exposed to excessive noise can even trigger a stress response. Unfortunately, these stress hormones make us more resistant to insulin, and therein lies the rub for people with diabetes.. When stress hormones are involved, most people with diabetes need more insulin to get the sugar into the cells. In addition, more sugar is released from the liver into the blood during stress because our brain needs more fuel to function. Its pretty clear how those two processes combined can make managing glucose levels hard for people with diabetes. Thank goodness for good tech! If you enter stress-related glucose values in the mySugr app, and note any stressful events when they occur, it can help you understand your bodys unique reaction ...
Insulin therapy is often an important part of diabetes treatment. In type 1 diabetes, the pancreas, a large gland behind the stomach, stops making insulin because the cells that make the insulin have been destroyed by the bodys immune system. Without insulin, the bodys cells cannot turn glucose (sugar), into energy. People with type 1 diabetes depend on insulin every day of their lives to replace the insulin the body cannot produce. Some people with type 2 diabetes require only oral medications for treatment. Other people will need to add insulin or another injectable medication because their blood sugar levels are not controlled. Insulin is usually given once per day, either in the morning or at bedtime. Small insulin doses are generally recommended when treatment first begins; the dose is adjusted over days, weeks, and months, once the bodys response to insulin treatment is known.

Many common diseases exhibit gender bias and gender differences have been observed in the development of high blood pressure (hypertension) and heart (cardiovascular) disease. Previous studies have reported that gender may affect vascular physiology and the bodys response to some types of blood pressure medications.
What happens to your body--and, perhaps more importantly, to your mind--when you drop 25-50% of your regular caloric intake (I tend towards the low end, at around 1600/day--its usually recommended that a man take in 2000 cal/day)? Epigentic changes are almost inevitable when the body takes punishment long enough; there is nearly indisputable evidence that most, if not all, psychiatric illnesses are due to how the genes are changed in response to environmental stressors. It only follows that the bodys responses to constant near-starvation would be to go through some changes, too. The science is still terribly convoluted as to exactly which genes get turned on and off and to what extent, but epigentic changes in response to calorie restriction happens, in yeast and mice, and, presumably, humans ...
