Immunohistochemical analysis of arterial wall cellular infiltration in Buerger's disease (endarteritis obliterans). (1/503)

PURPOSE: The diagnosis of Buerger's disease has depended on clinical symptoms and angiographic findings, whereas pathologic findings are considered to be of secondary importance. Arteries from patients with Buerger's tissue were analyzed histologically, including immunophenotyping of the infiltrating cells, to elucidate the nature of Buerger's disease as a vasculitis. METHODS: Thirty-three specimens from nine patients, in whom Buerger's disease was diagnosed on the basis of our clinical and angiographic criteria between 1980 and 1995 at Nagoya University Hospital, were studied. Immunohistochemical studies were performed on paraffin-embedded tissue with a labeled streptoavidin-biotin method. RESULTS: The general architecture of vessel walls was well preserved regardless of the stage of disease, and cell infiltration was observed mainly in the thrombus and the intima. Among infiltrating cells, CD3(+) T cells greatly outnumbered CD20(+) B cells. CD68(+) macrophages or S-100(+) dendritic cells were detected, especially in the intima during acute and subacute stages. All cases except one showed infiltration by the human leukocyte antigen-D region (HLA-DR) antigen-bearing macrophages and dendritic cells in the intima. Immunoglobulins G, A, and M (IgG, IgA, IgM) and complement factors 3d and 4c (C3d, C4c) were deposited along the internal elastic lamina. CONCLUSION: Buerger's disease is strictly an endarteritis that is introduced by T-cell mediated cellular immunity and by B-cell mediated humoral immunity associated with activation of macrophages or dendritic cells in the intima.  (+info)

Use of high-intensity focused ultrasound to control bleeding. (2/503)

OBJECTIVE: High-intensity focused ultrasound (HIFU) has been shown to be effective in controlling hemorrhage from punctures in blood vessels. The objective of the current study was to investigate the capability of HIFU to stop bleeding after a more severe type of vascular injury, namely longitudinal incisions of arteries and veins. METHODS: The superficial femoral arteries, common femoral arteries, carotid arteries, and jugular veins of four anesthetized pigs were exposed surgically. A longitudinal incision, 2 to 8 mm in length, was produced in the vessel. HIFU treatment was applied within 5 seconds of the onset of the bleeding. The HIFU probe consisted of a high-power, 3.5-MHz, piezoelectric transducer with an ellipsoidal focal spot that was 1 mm in cross section and 9 mm in axial dimension. The entire incision area was scanned with the HIFU beam at a rate of 15 to 25 times/second and a linear displacement of 5 to 10 mm. A total of 76 incisions and HIFU treatments were performed. RESULTS: Control of bleeding (major hemosatsis) was achieved in all 76 treatments, with complete hemostasis achieved in 69 treatments (91%). The average treatment times of major and complete hemostasis were 17 and 25 seconds, respectively. After the treatment, 74% of the vessels in which complete hemostasis was achieved were patent with distal blood flow and 26% were occluded. The HIFU-treated vessels showed a consistent coagulation of the adventitia surrounding the vessels, with a remarkably localized injury to the vessel wall. Extensive fibrin deposition at the treatment site was observed. CONCLUSION: HIFU may provide a useful method of achieving hemostasis for arteries and veins in a variety of clinical applications.  (+info)

Adventitial delivery minimizes the proinflammatory effects of adenoviral vectors. (3/503)

PURPOSE: Adenovirus-mediated arterial gene transfer is a promising tool in the study of vascular biology and the development of vascular gene therapy. However, intraluminal delivery of adenoviral vectors causes vascular inflammation and neointimal formation. Whether these complications could be avoided and gene transfer efficiency maintained by means of delivering adenoviral vectors via the adventitia was studied. METHODS: Replication-defective adenoviral vectors encoding a beta-galactosidase (beta-gal) gene (AdRSVnLacZ) or without a recombinant gene (AdNull) were infused into the lumen or the adventitia of rabbit carotid arteries. Two days after infusion of either AdRSVnLacZ (n = 8 adventitial, n = 8 luminal) or AdNull (n = 4 luminal), recombinant gene expression was quantitated by histochemistry (performed on tissue sections) and with a beta-gal activity assay (performed on vessel extracts). Inflammation caused by adenovirus infusion was assessed 14 days after infusion of either AdNull (n = 6) or vehicle (n = 6) into the carotid adventitia. Inflammation was assessed by means of examination of histologic sections for the presence of neointimal formation and infiltrating T cells and for the expression of markers of vascular cell activation (ICAM-1 and VCAM-1). To measure the systemic immune response to adventitial infusion of adenovirus, plasma samples (n = 3) were drawn 14 days after infusion of AdNull and assayed for neutralizing antibodies. RESULTS: Two days after luminal infusion of AdRSVnLacZ, approximately 30% of luminal endothelial cells expressed beta-gal. Similarly, 2 days after infusion of AdRSVnLacZ to the adventitia, approximately 30% of adventitial cells expressed beta-gal. beta-gal expression was present in the carotid adventitia, the internal jugular vein adventitia, and the vagus nerve perineurium. Elevated beta-gal activity (50- to 80-fold more than background; P <.05) was detected in extracts made from all AdRSVnLacZ-transduced arteries. The amount of recombinant protein expression per vessel did not differ significantly between vessels transduced via the adventitia (17.1 mU/mg total protein [range, 8.1 to 71.5]) and those transduced via a luminal approach (10.0 mU/mg total protein [range, 3.9 to 42.6]). Notably, adventitial delivery of AdNull did not cause neointimal formation. In addition, vascular inflammation in arteries transduced via the adventitia (ie, T-cell infiltrates and ICAM-1 expression) was confined to the adventitia, sparing both the intima and media. Antiadenoviral neutralizing antibodies were present in all rabbits after adventitial delivery of AdNull. CONCLUSION: Infusion of adenoviral vectors into the carotid artery adventitia achieves recombinant gene expression at a level equivalent to that achieved by means of intraluminal vector infusion. Because adventitial gene transfer can be performed by means of direct application during open surgical procedures, this technically simple procedure may be more clinically applicable than intraluminal delivery. Moreover, despite the generation of a systemic immune response, adventitial infusion had no detectable pathologic effects on the vascular intima or media. For these reasons, adventitial gene delivery may be a particularly useful experimental and clinical tool.  (+info)

An account of the longitudinal mucosal corrugations of the human tracheo-bronchial tree, with observations on those of some animals. (4/503)

A description is given of the distribution of the longitudinal mucosal corrugations in the human tracheo-bronchial tree. It has been shown that they are made up of elastic tissue in a collagen matrix, and that the elastic fibres continue into the smallest bronchioles beyond where the corrugations are no longer visible. An examination has also been made of the tracheo-bronchial trees of the hen, rat, raccoon, pig, sheep, llama and tiger. Corrugations are present in all these animals, except the hen and the raccoon, and they have been compared and contrasted with the condition in Man. The functional significance of these corrugations remains unknown, but, they could be important in equalizing tension in the tracheo-bronchial tree during inspiration, as well as in providing elastic recoil during expiration.  (+info)

Tissue-destructive macrophages in giant cell arteritis. (5/503)

Giant cell arteritis (GCA) is an inflammatory vasculopathy in which T cells and macrophages infiltrate the wall of medium and large arteries. Clinical consequences such as blindness and stroke are related to arterial occlusion. Formation of aortic aneurysms may result from necrosis of smooth muscle cells and fragmentation of elastic membranes. The molecular mechanisms of arterial wall injury in GCA are not understood. To identify mechanisms of arterial damage, gene expression in inflamed and unaffected temporal artery specimens was compared by differential display polymerase chain reaction. Genes differentially expressed in arterial lesions included 3 products encoded by the mitochondrial genome. Immunohistochemistry with antibodies specific for a 65-kDa mitochondrial antigen revealed that increased expression of mitochondrial products was characteristic of multinucleated giant cells and of CD68+ macrophages that cluster in the media and at the media-intima junction. 4-Hydroxy-2-nonenal adducts, products of lipid peroxidation, were detected on smooth muscle cells and on tissue infiltrating cells, in close proximity to multinucleated giant cells and CD68+ macrophages. Also, giant cells and macrophages with overexpression of mitochondrial products were able to synthesize metalloproteinase-2. Our data suggest that in the vascular lesions characteristic for GCA, a subset of macrophages has the potential to support several pathways of arterial injury, including the release of reactive oxygen species and the production of metalloproteinase-2. This macrophage subset is topographically defined and is also identified by overexpression of mitochondrial genes. Because these macrophages have a high potential to promote several mechanisms of arterial wall damage, they should be therapeutically targeted to prevent blood vessel destruction.  (+info)

Ultrastructural changes of the external elastic lamina in experimental hypercholesterolemic porcine coronary arteries. (6/503)

The external elastic lamina (EEL) serves as a barrier for cells and macromolecules between the media and adventitia in the vascular wall. We evaluated the morphological changes and quantitative assessments of the EEL architecture in the coronary circulation of pigs fed with a high cholesterol diet. Confocal microscopy analysis of the EEL from hypercholesterolemic coronary arteries revealed an altered pattern characterized by fragmentation and disorganization of the EEL associated with an increase in the thickness. Computerized digital analysis of the images obtained by confocal scanning microscopy demonstrated that compared to normal coronary arteries, the EEL of hypercholesterolemic coronary arteries decreased in the percentage of their elastin content (30.80 +/- 1.64% vs. 47.85 +/- 1.82%, p = 0.001). The percentage of elastin content was negatively correlated with the vessel wall area (r = -0.82, p = 0.001). The immunoreactivity for matrix metalloproteinase-3 (MMP-3) increased in cholesterol-fed coronary arteries, predominantly in the neointima and adventitia. This study demonstrates that experimental hypercholesterolemia induced ultrastructural changes of the EEL in coronary circulation. The EEL may also be an atherosclerosis-prone area compared with the intima. The EEL may play an important role in the development of structural changes which characterizes the early phase of coronary atherosclerosis and vascular remodeling.  (+info)

Transforming growth factor-beta1, -beta2, and -beta3 in vivo: effects on normal and mitomycin C-modulated conjunctival scarring. (7/503)

PURPOSE: To compare the effects of the three human isoforms of transforming growth factor (TGF)-beta in vivo using a mouse model of conjunctival scarring, both in normal eyes and after treatment with MMC, with a view to delineating the role of this growth factor in glaucoma filtration surgery. METHODS: Application of recombinant human TGF-beta was assessed in a prospective, randomized study of mouse conjunctival scarring, in which subconjunctival TGF-beta1, -beta2, and -beta3 (all 10(-9) M) were compared with control (phosphate-buffered saline [PBS] carrier) and mitomycin C (MMC; 0.4 mg/ml) treatment at 6 hours, and 1, 3, and 7 days after surgery (six eyes/treatment/time point). Effects of TGF-beta2 on eyes previously treated with MMC were also assessed. Histologic studies of enucleated eyes were performed to analyze development of the scarring response, extracellular matrix deposition, and the inflammatory cell profile. RESULTS: All three isoforms of TGF-beta behaved in a similar manner in vivo, being associated with a rapid-onset and exaggerated scarring response compared with control and MMC treatment. TGF-beta-treated eyes showed evidence of an earlier peak in inflammatory cell activity (P < 0.05) and increased collagen type III deposition (P < 0.05). TGF-beta2 treatment significantly stimulated scarring after MMC application (P < 0.05). CONCLUSIONS: TGF-beta1, -beta2, and -beta3 appear to have similar actions in vivo and stimulate the conjunctival scarring response. Application of TGF-beta2 modified the effects of MMC. All TGF-beta isoforms may be potent modulators of the conjunctival scarring response. These studies indicate that TGF-beta2 may naturally modify the antiscarring effects of antimetabolites such as MMC in glaucoma filtration surgery.  (+info)

Histology of the ligamentum flavum in patients with degenerative lumbar spinal stenosis. (8/503)

The degree of calcification as well as the structural changes of the elastic fibres in the ligamentum flavum in patients with degenerative lumbar spinal stenosis were evaluated and the results were compared to those of patients without spinal stenosis. In 21 patients (13 male, 8 female) with lumbar spinal stenosis the ligamentum flavum was removed, histologically processed and stained. The calcification, the elastic/collagenous fibre ratio as well as the configuration of the fibres were evaluated with an image analyzing computer. As a control group, 20 ligaments of 10 human corpses were processed in the same way. The results were statistically analysed using the Mann-Whitney-Wilcoxon test (alpha = 0.05) and the t-test (alpha = 0.05). Nearly all the ligaments of patients with lumbar spinal stenosis were calcified (average 0.17%, maximum 3.8%) and showed relevant fibrosis with decreased elastic/collagenous fibre ratio. There was a significant correlation between age and histological changes (P<0.05). In the control group we only found minimal calcification in 3 of 20 segments (average 0.015%). No relevant fibrosis was found and the configuration of elastic fibres showed no pathologic changes. The results of this study illustrate the important role of histological changes of the ligamentum flavum for the aetiology of lumbar spinal stenosis.  (+info)

A network of circumferentially oriented collagen fibrils exists in the periphery of the human cornea, and is thought to be pivotal in maintaining corneal biomechanical stability and curvature. However, it is unknown whether or not this key structural arrangement predominates throughout the entire corneal thickness or exists as a discrete feature at a particular tissue depth; or if it incorporates any elastic fibres and how, with respect to tissue depth, the circumcorneal annulus integrates with the orthogonally arranged collagen of the central cornea. To address these issues we performed a three-dimensional investigation of fibrous collagen and elastin architecture in the peripheral and central human cornea using synchrotron X-ray scattering and non-linear microscopy. This showed that the network of collagen fibrils circumscribing the human cornea is located in the posterior one-third of the tissue and is interlaced with significant numbers of mature elastic fibres which mirror the alignment of ...
To elucidate the role of the internal elastic lamina in the development of cerebral aneurysm, the bifurcation of the anterior cerebral artery and olfactory artery was histologically studied in control and experimental rats treated with unilateral carotid ligation and renal hypertension. Various stages of aneurysm formation were compared, and it was found that early aneurysmal changes were always present just distal to the apical intimal pad on the anterior cerebral artery side. The internal elastic lamina was thinned and fragmented just distal to the pad even in the very early stage of aneurysm formation when the medial layer was still present. In control rats, the internal elastic lamina had a tendency to thin and fragment at the site where aneurysms would develop in experimental rats. Our study shows that changes of the internal elastic lamina were present just distal to the pad even in control rats, which never develop cerebral aneurysms. Under hemodynamic stress augmented by experimental ...
The formation of a mature elastic fiber is thought to proceed by the deposition of elastin on pre-existing microfibrils (10-12 nm in diameter). Immunohistochemical evidence has suggested that in developing tissues such as aorta and ligamentum nuchae, small amounts of elastin are associated with microfibrils but are not detected at the light microscopic and ultrastructural levels. Dermal tissue contains a complex elastic fiber system consisting of three types of fibers--oxytalan, elaunin, and elastic--which are believed to differ in their relative contents of microfibrils and elastin. According to ultrastructural analysis, oxytalan fibers contain only microfibrils, elaunin fibers contain small quantities of amorphous elastin, and elastic fibers are predominantly elastin. Using indirect immunofluorescence techniques, we demonstrate in this study that nonamorphous elastin is associated with the oxytalan fibers. Frozen sections of normal skin were incubated with antibodies directed against human ...

Hi, Maybe my question is not well founded but I am under the impression that the articular hyaline cartilage contains elastic fibers. We have tried to correlate the presence of elastic fibers with enzymes within the cartilage under physiological and pathological conditions. In our hands, there are no elastic fibers in the cartilage stainable by Weigerts technique. Either I am mistaken and the cartilage is without elastic fibers, the fibers are there but masked by matrical components or

We find that the media and adventitia of adult human cerebral arteries contain elastic fibers forming a dense, coherent network, similar to that found in muscular arteries of the same size in other organs. The external elastic layer in the adult human is masked for the currently employed staining methods. By treatment with 90% formic acid before fixation, the original staining character of elastic tissue can be restored. The light microscopic and scanning electron microscopic features of this network of elastic fibers are presented. ...
Group 3 Peer Review The page is very good. The introduction is clearly and briefly and it gives a good idea about Elastic Fibres. The structure and components section is clearly, but I think a image would help to understand. Finally, I noticed that you did not put something about history and future researches that would be good in the beginning of the page. The Assembly of Elastic fibre is good too, and I really like the draw about the process of elastic fibre assembly. The other image (Role of MFAP-4 in Elastic fiber assembly) was well-chosen too. Finally, I like the step-by-step that you made in the final of section, because it summarizes the process being very informative and the reader can see the images at the same time. However, the images should be referenced correctly. The functions related with organs, like heart, lungs and skin was a great idea. Also, the clinical significance you chose relevant diseases to relate but I think you could explain more deeply how the elastic fibres are ...

The relatively high concentration in this pilot study was to be sure that the DHT receptors would all be blocked. The alcohol and water vehicle used in this pilot study was chosen in order to be certain that any beneficial effects would be from Ethocyn rather than from the vehicle. The tissue was stained with Verhoeffs stain so that the elastin stained black. At the end of the study the slides were randomized so that it was not known which slide was from which patient at which time and then photographed through the microscope with a camera which allowed the images to be stored on a computer. Computer image analysis was then performed to determine the percentage of surface area of each slide which took up the elastic tissue stain. After breaking the code it was found that the average increase in elastic tissue was about 100% as measured by computer image analysis. The findings of this study were statistically significant at a level of p ...

The elastic fibers and fabrics can be used to produce structures that can have recycle compatibility between elastic and non elastic components. The novel fibers have at least about 50% recovery at 100% strain. The fibers and fabrics are especially useful in making fabricated articles and components thereof (e.g., disposable diapers).
Under several emerging application scenarios, such as in smart cities, operational monitoring of large infrastructure, wearable assistance, and Internet of Things, continuous data streams must be processed under very short delays. Several solutions, including multiple software engines, have been developed for processing unbounded data streams in a scalable and efficient manner. More recently, architecture has been proposed to use edge computing for data stream processing. This paper surveys state of the art on stream processing engines and mechanisms for exploiting resource elasticity features of cloud computing in stream processing. Resource elasticity allows for an application or service to scale out/in according to fluctuating demands. Although such features have been extensively investigated for enterprise applications, stream processing poses challenges on achieving elastic systems that can make efficient resource management decisions based on current load. Elasticity becomes even more challenging
Pay-as-you-go is one of the basic properties of Cloud computing. It means that people pay for the resources or services that they use. Moreover, the concept of load balancing has been a controversial issue in recent years. It is a method that is used to split a task to some smaller tasks and allocate them fairly to different resources resulting in a better performance. Considering these two concepts, the idea of Elasticity comes to attention. An Elastic system is one which adds or releases the resources based on the changes of the system variables. In this thesis, we extended a distributed storage called Voldemort by adding a controller to provide elasticity.. Control theory was used to design this controller. In addition, we used Yahoo! Cloud Service Benchmark (YCSB) which is an open source framework that can be used to provide several load scenarios, as well as evaluating the controller. Automatic control is accomplished by adding or removing nodes in Voldemort by considering changes in the ...
In this manuscript with Lev Truskinovsky, we developed a new nonlinear theory of large-strain incompatible surface growth. Surface growth is a crucial component of many natural and artificial processes from cell proliferation to additive manufacturing. In elastic systems, surface growth is usually accompanied by the development of geometrical incompatibility leading to residual stresses and triggering various instabilities. Here we developed a nonlinear theory of incompatible surface growth which quantitatively linkes deposition protocols with post-growth states of stress. ...
In the mouse model of MFS, we detected upregulation of MMP-2 and -9 in mRNA and protein expression in the aneurysmal TA during disease progression. Consistent with a previous study,5 increased TIMP-1 and -2 protein levels were observed during aneurysm formation in MFS. The novelty of the present study is the demonstration of the differential regulation of TIMP-1 and -2 in MFS. In the dilated TA, the greater ratio of MMP-2/TIMP-2 would favor elastinolysis especially in the early stage, whereas a slight reduction of MMP-9/TIMP-1 ratio might be a compensatory mechanism to protect from extensive vascular remodeling at the end-stage lesion (Figure 1C and 1D). We also showed that the upregulation of MMP generally correlated with the extent of loss of elastic content and elastic fiber architecture during TAA formation (Figures 1 through 3⇑⇑). In patients with dilatation or dissection of the ascending TA associated with MFS, fragmentation of elastic fibers, fibrosis with collagen production and ...
Male and female breeder rats spontaneously develop arteriosclerosis. This occurs first in the aorta and coronary arteries and subsequently in the carotid and intracranial arteries. The carotid arteries show mesenchymal cell proliferation in the media followed by subintimal swelling and mucoid deposition, elastosis, cartilaginous metaplasia and eventual bone formation. Lipid deposition occurs infrequently, and then only in advanced lesions in the media. Severe lesions are much more frequent in the female breeder and the tendency towards cartilaginous metaplasia and bone formation is peculiar to the carotid arteries. The cerebral arteries show little arteriosclerotic involvement except for aneurysm-like outpouchings of the internal elastic membrane associated with mucopolysaccha-ride accumulation about the sites of elastic tissue disruption. Despite severe fulminating arteriosclerosis in the carotid arteries, the cerebral arteries and the brain tissue itself show little or no significant evidence ...

There is provided an elastic laminate of a base layer with one or more attached elastic elements forming an elastic region. The elastic region width varies from a terminal end of the elastic tab to a proximal end of the elastic tab such that a width adjacent the terminal end is 20 to 80 percent narrower than a width adjacent the proximal end. The elastic region is defined by a plurality of segments, having differing average widths in the length direction of the elastic tab elastic region. The one or more elastic elements vary in one or more properties such that a plurality of the segments having different widths have substantially the same degree of elongation at a given elongation of the shaped elastic tab laminate.
Our immunohistochemistry data revealed that fibrillin-1 is a major connective tissue protein in the normal adult rodent myocardium. It was relatively abundant and expressed throughout the myocardium as thin fibers that crossed over myofibril bundles and around intramural coronary arteries and arterioles. Fibrillin-1-positive fibers were oriented in the longitudinal axis of myocytes, and this spatial arrangement suggested that these microfibrils have an important role in transmitting forces from myocytes to the extracellular connective tissue framework.. In many elastic tissues, such as arteries, fibrillin-1, being the major constituent of microfibrils, is observed in close association with amorphous elastin. Except in valvular leaflets and in coronary arteries, the proportion of elastin in the interstitial myocardium is considerably less (16), and elastin does not appear to be an important constituent on this interstitial matrix.. This study reports a significant increase in fibrillin-1 ...
A blood vessel carrying blood away from the heart. All arteries except the pulmonary artery carry oxygenated blood. The walls of an artery consist of three layers: an inner layer (tunica intima), a middle smooth muscle and elastic tissue layer ( tunica media), and an outer fibrous layer ( tunica adventitia, tunica externa). See Appendix C for the main arteries of the head and neck Arteries of the head and neck. ...
Cindy, we do a considerable amount of vessel work, quite a bit in swine. historically we have always looked for internal elastica to evaluate the amount of neo-intimal proliferation and muscle/collagen changes. to this end, in addition to an H&E, we always did two seperate stains: a Verhoeff stain for elastica and a Massons trichrome for the collagen. to minimize work we simply combined the two stains, later to find out that we had devised a variation of a stain that is already in the literature. i hope the reference helps. did they not reference the stain in the italian paper you mentioned? hope this is what you are looking for. i would agree with Russ that the VG stain could be considered a 3 color stain, but am not sure about the blue and green he mentioned in his reply (i expect he was suggesting those colors in other trichrome stains --- if not, maybe he could provide a reference???). we usually use picric acid for staining the muscle component, though as most will agree, thats as non ...
Weve spoken recently of how the body makes use of tensegrity to help hold itself together. We stretch out our soft tissues and they resist further expansion and create a sea of continuous tension that tugs on and supports the bones suspended within it. Soft tissue and bone working together.. Because the soft tissues resist further expansion, they supply an ever-present, wall-to-wall, continuous pull inward on the bones. The bones, by refusing further compression, push outward locally on the soft tissues surrounding them and prevent our structure from collapsing in on itself. We create a form that is less stiff, more resilient than one relying on continuous compression.. Thinking of the bodys architecture this way leads us to view the elastic, distensible elements of the body in a new light.. If we use the word tendon to mean any soft, elastic tissue that contributes to a web of continuous tension, we begin to see many structures of the body as tendon: the lungs that want to spring back once ...
(Epimysium labeled at bottom center.) Muscle Cell Definition: A muscle cell is also known as Myocyte, which is a specialized animal cell that can shorten its length by using a series of motor proteins especially arranged in the cell. Generally, they serve as passive structures, which reduce the friction of muscular force. Discover (and save!) And several other associated proteins help, actin, and myosin form thin and thick filaments that slide past each other in order to contract small units of the muscle cell. [2] It is a layer of dense irregular connective tissue which ensheaths the entire muscle and protects muscles from friction against other muscles and bones. Muscles are surrounded and subdivided by connective tissue sheaths. The outermost fibrous sheath that covers a muscle continuous with the perimysium. N pl sia anatomy the sheath of connective tissue that encloses a. Epimysium is defined by the lexicographers at oxford dictionaries as a sheath of fibrous elastic tissue surrounding a muscle. It

With arthritis (osteoarthritis) identified as one of the most common diseases seen and treated in veterinary practice, it is often asked whether specialised food and nutritional supplements can really make a difference to our pets wellbeing.. So firstly, what is arthritis? Arthritis involves the ongoing breakdown of the joint cartilage (a tough, elastic tissue that protects the underlying bone). It is quite common, particularly in our ageing pets and affects one in four dogs and one in five cats (all ages combined).. Arthritis is also seen more often in medium to large breed dogs; but it can occur in pets of any age and breed. Certain situations can cause wearing or damage to the joints, increasing the risk of arthritis developing.. ...
Its fun to look at family albums. Hopefully lots of good memories of good times. But when those albums span decades, you cant help but notice that the peoples faces look different as they get older. No, not because they came to my office for cosmetic procedures, but actually because they didnt, and thats just the point. What you are seeing is the natural aging process of the face. And today Im going to explain what causes those changes whether you see them in your album or in your mirror. The essential process that is responsible for the aging face is age related loss of fat in your face and age and sun related loss of elastic tissue in your facial skin. And theres also some subtle bone changes in your facial bones that contribute to these changes.. Ill use a series of diagrams to show you whats happening and when I refer to ages, of course theyre only approximate and aging occurs differently for everybody. So, this is the shape and contours of a youthful face, 20s thru early ...
