A foreign body granuloma is a mass lesion consisting of a foreign body with host reaction. Its diagnosis is not always easy in respect of its similarity to soft tissue sarcoma. The most common foreign body is surgical sponge which can be detectable macroscopically. We present a foreign body granuloma in the left buttock caused by microscopic surgical materials that developed into a large lesion. An 80-year-old man with a history of surgery for dislocation of the left hip 20 years earlier, presented with a slowly growing mass that had expanded rapidly over the preceding 2 months. Histological examination revealed organizing granulation tissue surrounding the scattered foreign materials. One should be aware of foreign body granuloma at previously operated sites even without a retained macroscopic gauze sponge.
Foreign body granulomas in the skin have been described frequently and may have various causes. Diagnosis is relatively easy in most cases, as most are related to foreign material penetrating into the skin due to different kinds of traumas. We present the case of a boy with multiple facial granulomas, persisting more than 6 months and related to the use of topical anti-pruriginous talc powder applied to papuloexudative lesions caused by varicella. Data gathered in the anamnesis, examination with polarized light and images seen through the electron microscope enabled us to identify the causal agent talc as the inducer of the granulomatous lesions that the patient presented, discarding other types of foreign body granulomas of exogenous origin. ...
One of the basic features of vertebrate cellular physiology is the ability of the organism to distinguish self from nonself This distinction is at times tenuous, since the body reacts to some of its own products as if they were foreign material, while some surgically implanted prosthetic materials may provoke little or no reaction at all ...
This is the first report to describe the laparoscopic removal of an FB-induced granuloma from the abdomen of a cheetah. Granuloma formation in this species has not been well described. Similarly, reports on laparoscopic surgery in this species are sparse, particularly those describing the laparoscopic excision of abdominal masses.. The cheetah is known for its strong cellular immune system and probably limited requirement for a humoral response to bacterial infection (Wachter 2014). In this cheetah, a well-encapsulated and omentalised FB was detected by ultrasound before surgery and confirmed by intraoperative cytology. The small amount of free peritoneal fluid was indicative of the marked extent to which this patient could encapsulate FB.. Standard straight laparoscopic instruments have been reported to create instrument cluttering when applied through a single access port (Manassero and others 2012, Runge and others 2012, Wilson and Monnet 2012, Runge and Mayhew 2013) and curved or articulated ...

The actual incidence of gossypiboma is difficult to determine, possibly due to a reluctance to report occurrences arising from fear of legal repercussions, but retained surgical sponges is reported to occur once in every 3000 to 5000 abdominal operations[2] and are most frequently discovered in the abdomen.[3] The incidence of retained foreign bodies following surgery has a reported rate of 0.01% to 0.001%, of which gossypibomas make up 80% of cases.[1] Gossypibomas can often present, clinically or radiologically, similar to tumors and abscesses, with widely variable complications and manifestations, making diagnosis difficult and causing significant patient morbidity.[3] Two major types of reaction occur in response to retained surgical foreign bodies. In the first type, an abscess may form with or without a secondary bacterial infection. The second reaction is an aseptic fibrinous response, resulting in tissue adhesions and encapsulation and eventually foreign body granuloma.[1] Symptoms may ...
Hyperuricemia causes urates to be deposited in the skin and sometimes in the subcutaneous fat. Visit: Pathology of Urate deposits. Gouty tophi are the pathognomonic hallmark of gout. They are formed by large aggregations of urate crystals surrounded by an intense inflammatory reaction of macrophages, lymphocytes and large foreign body giant cells which may have completely or partially engulfed mass of crystals.. Tophi may appear in the articular cartilage of joints and also in the periarticular ligaments, tendons, soft tissues including the olecranon and patellar bursae, Achilles tendons, and ear lobes. Less frequently they may appear in the kidneys, nasal cartilages, skin of the fingertips, palms and sole. Superficial tophi can lead to large ulcerations of the overlying skin.

And so it was that yesterday Lynn and I set out to Bransbury on the River Test close to my home to see if we could find Sloe Pug larvae. They overwinter as eggs that emerge as the blackthorn starts to blossom and the traditional method is to beat the taller arching branches over a beating tray. I should say that the larvae are white with a reddish dorsal line and are remarkably well camouflaged on the blackthorn flowers on which they feed. Even the head capsule looks remarkably like an anther on the end of the stamens. So I knew what we were looking for, and theoretically how to find them, but after three of hours of beating the blackthorn and carefully inspecting the contents of the tray we had found nothing more than a couple of other geometer larvae - I hadnt expected it to be this difficult! But I wasnt going to give up that easily and we moved into a slightly more sheltered area where there was no obvious grazing line on the bushes and bingo! Two small larvae on the tray one of which was ...
Scanning electron microscopy of tests of Triticites ventricosus and Schwagerina sp. shows that the microgranular wall was secreted rather than agglutinated. Grains range in size from 0.5 to 6.0 μm, but grains larger than 4 μm are rare. Evidence that grains were secreted includes tight packing, uniform size and shape, and apparently homogeneous composition. Furthermore, scanning electron microscopy confirms the perforate nature of the antetheca and the nature of the keriothecal wall. Alveoli taper toward the tectum and pass through the tectum as tiny pores, enhancing communication between chambers and with the external environment.. The traditional model for the addition of chambers is rejected. Three ways in which new chambers may have been added to the test that are consistent with observations made here: 1) The antetheca may have thickened differentially, creating a substrate to which the keriotheca of the new chamber was attached; 2) Part of the tectum, septum, and keriotheca of the ...

Ive never layed a hedge myself, but I have seen it done. You cut part way through the lower branches until you can bend them down to fill the gaps. You can peg them in place, or leave them lying and then weave them in as they grow. I beleive it is very effective when it is done well, but, it all takes time to establish. I think its a great plan, because the availability of relatively cheap fencing has led to the practice dwindling. Anyone taking it up is contributing to a revival - a good thing for saving on wooden fence posts and establishing more hedgerose. I am going to have a go myself when my hedges have grown sufficiently. I dont know if it will prove to be animal proof, but I hope to try. ...
Breast carcinoma rarely occurs in cases of foreign body granulomas following liquid silicone injection. Although the Food and Drug Administration (FDA) banned the use of all silicone injection products in 1992, liquid silicone injection for breast augmentation continues to be performed illegally. We herein report a case of breast carcinoma following liquid silicone injection in a 67-year-old female. A total of 45 years after liquid silicone injection, the patient had felt a breast mass in the right breast. Mammography showed a smooth mass that retracted the right nipple. Due to the presence of a marked acoustic shadow caused by the granulomas, evaluating the mass on ultrasonography was difficult. However, magnetic resonance imaging (MRI) showed a lobulated mass under the right nipple. The mass exhibited low signal intensity (SI) on T1-weighted images and intermingled high and low SI on T2-weighted images. Heterogeneous early enhancement with central low intensity was noted on dynamic contrast-enhanced
A close exposure of the eyes of synthetic materialused in stuffed toy animals, blankets, beddings andpullover sweaters may cause penetration of the conjunctivaby synthetic fibres. Usually, foreign bodies,that comes into contact with the ocular surface areremoved by the eye protective mechanisms as blinkingand tearing (2, 4, 5). Occasionally, foreign bodiesmay be retained in the eyelid fornix, encapsulated bythe mucous, embedded in the underlying stroma andmay induce a local inflammatory response (6, 7, 8).This may cause synthetic fibre granuloma formation inthe conjunctiva, which condition is commonly knownas „teddy bear" granuloma because of the origin ofthe synthetic fibres (1, 2).. Foreign body granulomas of the conjunctiva causedby synthetic fibres were first described by Weinbergand associates, in 1984.3 Since then eighteen caseshave been reported in the literature (1). The ages ofthe reported patients ranged from 26 months to 17years (2, 3). The granulomas usually were presented asa ...

Discussion. The foot is the second-most common location for retained foreign bodies.3 Such retention is especially frequent in developing countries where walking barefoot is very common. Thus the feet are at risk for trivial injuries, which can result in inflammation or infection.4 The foreign bodies most often retained in the hand and foot are thorns, glass, needles or wooden fragments. Retention of these foreign bodies results in a soft-tissue or bony granuloma.5 A retained foreign body can present in numerous ways, including mechanical dermatitis, cellulitis, abscess, foreign-body granuloma, peritendonitis, tendonitis, pericapsulitis, synovitis, acute septic arthritis or chronic monoarticular non-suppurative inflammation. Many aetiologies have been described to explain the pathogenesis in the sudden flare-up after a period of latency: low-grade infection, protein coating of the foreign body, toxins, mitogens in the foreign body and the crystalline structures of the foreign bodies.1 Taking a ...
Charcoal, also called black carbon, is used for preoperative localization of tumor (mainly for breast tumors) or needle track localization after biopsy (mainly sarcomas biopsy, due to a potential risk of tumor seeding along needle track with this type of tumor).. Foreign-body granulomas can lead to false-positive findings of FDG PET/CT due to strong FGD uptake. On unenhanced CT, granulomas can show variable configurations, as delimited oval or round shape, or amorphous and linear configuration. Charcoal-induced granulomas usually show a spontaneous high attenuation, due to the high density of carbon particles, and no remarkable enhancement after contrast injection. On US studies, charcoal granulomas are characterized as irregular-shaped lesions, most often with hyperechogenicity and posterior shadowing. On the contrary, tumor recurrences often appear hypoechoic.. As described by Jin Woo Choi, charcoal is known to be a safe and biologically inert material when injected subcutaneously and may ...

Single wall carbon nanotubes (SWCNTs) are preferred vehicle for nano drug delivery in cancer therapy. However, the effects of SWCNTs alone in vivo situations are not well explored. Thus, the need of the hour is to find out SWCNTs induced cellular reactions within the organism using standard neurotoxicological approaches. Since military personnel are often inflicted with brain or spinal cord injury during combat operations either by gunshot, missile explosions, fall or direct blunt or sharp trauma to their CNS inducing life threatening illnesses, we have undertaken a series of investigation to study nanodrug delivery and its consequences in animal models using in vivo research. We found that SWCNTs alone induced potential neuronal injuries that is size and dose related indicating a need to find out co-administration of suitable drugs to reduce SWCNTs induced brain pathology in vivo. In this connection Cerebrolsyin, a balanced composition of several neurotrophic factors and active peptide fragments is
We thank you very much for allowing us to respond to the letter by Marchiori et al1 submitted in response to our recently published paper titled Parasitic infections of the lung: a guide for the respiratory physician.2. We agree with the authors that the condition may be a difficult diagnostic challenge, but in textilomas (gossypibomas) there is nearly always a history of previous surgery. In a fairly large series of CT scans performed on textilomas, Kopka et al3 observed that in seven patients gas bubbles were found inside the textiloma with a typical pattern. These patients did not have any abscess formation; however, it is interesting to note that the radio-opaque marker inside a textiloma was seen in nine patients but did not lead to a diagnosis in all of them. The authors also found that, from in vitro studies, gas bubbles were demonstrated in all surgical sponges scanned 1 hour afterwards. It is interesting that the number of gas bubbles were not significantly reduced after 6 months. CT ...

The Raman D-band feature (∼1350 cm[-][1]) is examined with 2.54 eV excitation for pure bulk carbon single-wall nanotube samples before and after treatments that increase defect densities. Upon employing mass-transport-limited oxidation to introduce defects, the D-band intensity increases approximately linearly with reaction time. A relatively constant ratio of the D-band intensity and the major tangential G-band intensity (D/G) is observed for the purified samples examined at 2.54 and 1.96 eV suggesting a characteristic number of defects is introduced for given synthesis and purification processes. The DIG ratio is ∼1/90 and 1/40 for excitation at 2.54 and 1.96 eV, respectively ...

This invention relates generally to a forming an array of single-wall carbon nanotubes (SWNT) in an electric field and compositions thereof. In one embodiment, a purified bucky paper of single-wall carbon nanotubes is used as the starting material. Upon oxidative treatment of the bucky paper surface, many tube and/or rope ends protrude up from the surface of the paper. Disposing the resulting bucky paper in an electric field results in the protruding tubes and or ropes of single-wall carbon nanotubes aligning in a direction substantially perpendicular to the paper surface. These tubes tend to coalesce to form a molecular array. In another embodiment, a molecular array of SWNTs can be made by "combing" the purified bucky paper starting material with a sharp microscopic tip to align the nanotubes ...
On December 20, 2011, the National Institute of Standards and Technology (NIST) announced it issued the worlds first reference material for single-wall carbon nanotube soot. According to NIST, "nanotube-laden soot is the primary industrial source of single-wall carbon nanotubes, perhaps the archetype of all nanoscale materials." NIST states that the new material "offers companies and researchers a badly needed source of uniform and well-characterized carbon nanotube soot for material comparisons, as well as chemical and toxicity analysis." ...
This invention relates generally to a method for growing single-wall carbon nanotube (SWNT) from seed molecules. The supported or unsupported SWNT seed materials can be combined with a suitable growth catalyst by opening SWNT molecule ends and depositing a metal atom cluster. In one embodiment, a suspension of seed particles containing attached catalysts is injected into an evaporation zone to provide an entrained reactive nanoparticle. A carbonaceous feedstock gas is then introduced into the nanoparticle stream under conditions to grow single-wall carbon nanotubes. Recovery of the product produced can be done by filtration, centrifugation and the like ...
C59N magnetic fullerenes inside single-wall carbon nanotubes (SWCNTs) are used to probe the density of states (DOS) on the host tubes using electron spin resonance (ESR). The C59N radicals are separated by C60 fullerenes to prevent dimerization and C59N-C60 heterodimers are formed at low temperatures. The electron spin-lattice relaxation time, T1, of the heterodimers is deduced from the homogeneous ESR line-width. The analysis is supported by saturation ESR studies. The inverse of the heterodimer T1 follows a linear behavior in the 20-300 K temperature range, the so-called Korringa law, evidencing a metallic DOS on all tubes in a bundle.

U937 cells were differentiated with phorbol 12-myristate 13-acetate, and cocultured with either retrieved polyethylene particles or commercially produced polyethylene particles (Ceridust 3615, Clariant Japan, Tokyo, Japan). To achieve consistent contact with the polyethylene particles, we used a rotating device. Phagocytosis of the polyethylene particles or retrieved polyethylene particles by differentiated U937 cells stimulated the release of cytokines including interleukin 1β, interleukin 6, interleukin 8, and vascular endothelial growth factor. Microarray analysis revealed that ...

Field emission properties of single wall carbon nanotubes (SWCNTs) grown on iron catalyst film by plasma enhanced chemical vapour deposition system were studied in diode configuration. The results were analysed in the framework of Fowler-Nordheim theory. The grown SWCNTs were found to be excellent field emitters, having emission current density higher than 20 mA/cm{sup 2} at a turn-on field of 1.3 V/μm. The as grown SWCNTs were further treated with Oxygen (O{sub 2}) plasma for 5 min and again field emission characteristics were measured. The O{sub 2} plasma treated SWCNTs have shown dramatic improvement in their field emission properties with emission current density of 111 mA/cm{sup 2} at a much lower turn on field of 0.8 V/μm. The as grown as well as plasma treated SWCNTs were also characterized by various techniques, such as scanning electron microscopy, high resolution transmission electron microscopy, Raman spectroscopy, and Fourier transform infrared spectroscopy before and after O{sub ...

There are two theories for the development of a cholesterol granuloma. In the obstruction-vacuum theory, Eustachian tube dysfunction is thought to cause mucosal edema, which can result in repeated episodes of bleeding and subsequent formation of cysts surrounding the blood. The cysts gradually expand.. In the exposed marrow theory, on the other hand, hyperplastic mucosa is thought to invade underlying bone and expose the bone marrow, which, in turn, bleeds.. Either way, a combination of trapped blood and a surrounding chronic inflammatory response lead to the formation of a cholesterol granuloma. In our patient, the etiology is most likely related to Eustachian tube obstruction caused by previous surgery and radiation for a trigeminal schwannoma.. Histologically, cholesterol granulomas contain yellow-brown fluid consisting of cholesterol crystals, red blood cells, and blood break-down products.. Cholesterol granulomas are surrounded by a fibrous tissue capsule and can be located in any part of ...

Autori: Yuan Chen, Dragos Ciuparu, Sangyun Lim, Yanhui Yang, Gary L. Haller and Lisa Pfefferle. Editorial: Journal of Catalysis, 225(2), p.453-465, 2004.. Rezumat:. Catalyst pretreatment and CO disproportionation reaction conditions were observed to strongly affect the diameter uniformity of single-wall carbon nanotubes (SWNT) grown on Co-MCM-41 catalysts. The prereduction and CO disproportionation reaction temperatures were varied systematically while the carbon loading and the SWNT diameter uniformity were monitored by TGA, Raman spectroscopy, and TEM. The state of the catalyst during prereduction and the size of the cobalt clusters formed during the SWNT growth process were monitored by in situ XANES during the prereduction of the Co-MCM-41, and ex situ EXAFS of catalyst samples was performed after carbon deposition. These experiments allow development of correlations between the SWNT quality and the state of the catalyst. Control of the cobalt cluster size in the Co-MCM-41 catalyst is ...

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. ...
