Here, we show for the first time, the contribution of relaxin and also of β-estradiol to the degradation of TMJ fibrocartilage and (to a lesser extent) of knee articular cartilage in vivo, the lack of potentiation of these responses to relaxin by β-estradiol, and progesterones prevention of matrix loss mediated by β-estradiol and/or relaxin. These findings suggest that, by modulating the remodeling of the ECM of cartilage, these hormones may play an important regulatory role in the normal and pathologic metabolism of cartilaginous tissues. In the latter scenario, it is conceivable that individuals with abnormal absolute or relative levels of one or more of these hormones or their receptors might incur progressive loss of matrix macromolecules, leading to joint disorders characterized by the degeneration of specific cartilages or fibrocartilages [27]. Such potential hormone-mediated changes in the composition of the ECM can significantly impact the ability of joints to sustain and distribute ...

Apparatus and methods for repairing damaged tendons or ligaments. Various repair apparatus include an elongate tensile member and a pair of anchor assemblies connected for movement along the tensile member on either side of a repair site, such as a tear or laceration. The anchor assemblies or structures may take many forms, and may include barbed, helical, and crimp-type anchors. In the preferred embodiments, at least one anchor structure is movable along the elongate tensile member to assist with adjusting a tendon segment to an appropriate repair position and the anchor structure or structures are then lockable onto the elongate tensile member to assist with affixing the tendon at the repair position. Tendon and/or ligament-to-bone repair apparatus and methods employ similar concepts.

My PhD focussed primarily on the structure, function, and pathology of entheses, specifically on the calcaneal (Achilles) tendon enthesis organ. An enthesis is the site of attachment of a tendon, ligament or joint capsule to bone. However, at most sites, entheses are not isolated structures; they are frequently associated with other components including adipose tissue and synovium. My PhD illustrated that although entheses are common sites of pain in pathology, under normal conditions, the enthesis itself and associated fibrocartilages are avascular and aneural. The related adipose tissue, however, is highly innervated and may therefore play a role in proprioception, and potentially be a source of pain in enthesopathies. From this research I have developed an interest in the functional role of adipose tissue in the musculoskeletal system and have recently supervised projects which investigated the structure and development of the plantar fat pads.. Since starting as a Professional Tutor I have ...
The ligament-bone interface is a complex structure that comprises ligament, fibrocartilage, and bone. We hypothesize that mesenchymal stem cells cocultured in between ligament and bone cells, on a hybrid silk scaffold with sections suitable for each cell type, would differentiate into fibrocartilage. The section of scaffold for osteoblast seeding was coated with hydroxyapatite. A trilineage coculture system (osteoblasts-BMSCs-fibroblasts) on a hybrid silk scaffold was established. RT-PCR results and immunohistochemistry results demonstrated that BMSCs cocultured between fibroblasts and osteoblasts had differentiated into the fibrocartilaginous lineage. The morphological change was also observed by SEM observation. A gradual transition from the uncalcified to the calcified region was formed in the cocultured BMSCs from the region that directly interacted with fibroblasts to the region that directly interacted with osteoblasts. The role of transforming growth factor β3 (TGF-β3) in this ...
In severe injuries with loss of tendon substance a tendon graft or a synthetic substitute is usually used to restore functional length. This is usually associated with donor site morbidity, host tissue reactions and lack of remodelling of the synthetic substitutes, which may result in suboptimal outcome. A biocompatible graft with mechanical and structural properties that replicate those of normal tendon and ligament has so far not been identified. The use of demineralised bone for tendon reattachment onto bone has been shown to be effective in promoting the regeneration of a normal enthesis. Because of its properties, we proposed that Demineralised Cortical Bone (DCB) could be used in repair of a large tendon defect. Allogenic DCB grafts in strip form were prepared from sheep cortical bone by acid decalcification and used to replace the enthesis and distal 1 cm of the ovine patellar tendon adjacent to the tibial tuberosity. In 6 animals the DCB strip was used to bridge the gap between the resected end

This condition is quite common in dogs although it is very rare in cats. It is really a type of stroke that affects the spinal cord instead of the brain. In this case the stroke is caused by small pieces of disc material that somehow get into the blood vessels supplying the spinal cord to cause a blockage. Clinical signs are therefore very sudden in onset and often cause immediate paralysis of one limb, of the rear limbs or sometimes of all four limbs. The animals may be painful initially but the pain usually resolves completely within a few hours. Diagnosis depends on ruling out other potential causes of the signs such as a [intlink id=1466″ type=post]fracture[/intlink] or [intlink id=1436″ type=post]disc disease[/intlink]. There is no treatment although physical therapy has been shown to influence recovery favorably. The completeness of the animals recovery depends mainly on how much of the spinal cord has been damaged by the injury and this is best determined by a neurological ...

clear areas of condylar regeneration are observed with sectors of cortical bone formation.. DISCUSSION. UCH has been widely analyzed in recent years without obtaining any clear consensus in terms of etiology and diagnosis (Olate et al., 2013b; Wolford et al., 2014). The studies conducted to determine its physiopathology have not been conclusive, indicating some histological aspects of the disease without managing to identify the processes involved in its development or sequence (Saridin et al., 2010). It has been established that fibrocartilage growth is part of the development of the disease (Saridin et al.; Eslami et al., 2003), whereas histopathological classifications of normality and disease have not been clear in terms of criteria.. The morphological characteristics of the UCH have been reported clinically with the classic facial asymmetry, chin deviation and unilateral cross-bite (Olate et al., 2013a), which being progressive help to determine the activity of the disease.

The aim of this study was to determine if treatment with reversine, a purine analog, promoted generation of skeletal progenitor cells from lineage-committed annulus fibrosus cells. Reversine modulated cell growth, morphology, and the actin cytoskeleton of annulus fibrosus cells. Microarray profiling coupled with Ingenuity Pathway Analysis revealed that reversine treatment resulted in a significant expression change in many genes including those required for cell-cell interaction, cell movement, cell growth, and development. Further analysis revealed that there was involvement of gene networks concerned with cellular assembly and organization, DNA replication and repair, tissue morphology, and cell-to-cell signaling. The gene expression profile was dependent on reversine concentration. In osteogenic media, cells pretreated with 300nM reversine exhibited an increased induction in alkaline phosphatase activity and enhanced expression of alkaline phosphatase, bone sialoprotein, osteocalcin, and ...

Despite the high prevalence of intervertebral disc disease, little is known about changes in intervertebral disc cells and their regenerative potential with ageing and intervertebral disc degeneration. Here we identify populations of progenitor cells that are Tie2 positive (Tie2+) and disialoganglioside 2 positive (GD2+), in the nucleus pulposus from mice and humans. These cells form spheroid colonies that express type II collagen and aggrecan. They are clonally multipotent and differentiated into mesenchymal lineages and induced reorganization of nucleus pulposus tissue when transplanted into non-obese diabetic/severe combined immunodeficient mice. The frequency of Tie2+ cells in tissues from patients decreases markedly with age and degeneration of the intervertebral disc, suggesting exhaustion of their capacity for regeneration. However, progenitor cells (Tie2+GD2+) can be induced from their precursor cells (Tie2+GD2-) under simple culture conditions. Moreover, angiopoietin-1, a ligand of Tie2, is
Spondylosis is mainly caused by ageing. As people age, certain biological and chemical changes cause tissues throughout the body to degenerate. In the spine, the vertebrae (spinal bones) and intervertebral discs degenerate with ageing. the intervertebral discs are cushion like structures that act as shock absorbers between the vertebral bones.. One of the structures that form the discs is known as the annulus fibrosus. The annulus fibrosus is made up of the 60 or more tough circular bands of collagen fiber (called lamellae). Collagen is a type of inelastic fiber. Collagen fibers, along with water and proteoglycans (types of large molecules made of a protein and at least one carbohydrate chain) help to form the soft, gel-like center part of each disk. This soft, center part is known as the nucleus pulposus and is surrounded by the annulus fibrosus.. The degenerative effects of ageing can cause the fibers of the discs to weaken, causing wear and tear. Constant wear and tear and injury to the ...
Tendon attaches to bone through a hierarchical and spatial graded structure called the enthesis. Entheses at the rotator cuff of the humeral head are highly resilient against injury in younger adults, but tears are common in older adults. These heal poorly, even following surgery. A central challenge is that potentially important nanoscale features of the material at these enthesis sites are not regenerated following injury or surgery. Our group aims to identify the nanoscale structures that are most important to the resilience of the enthesis, and to develop strategies for reconstituting these during healing. Here, we will present an overview of our recent results on ways that both structured and stochastic features might contribute to the mechanical functioning of the healthy enthesis.
Regeneration of complex tissues, such as kidney, liver, and cartilage, continues to be a scientific and translational challenge. Survival of ex vivo cultured, transplanted cells in tissue grafts is among one of the key barriers. Meniscus is a complex tissue consisting of collagen fibers and proteoglycans with gradient phenotypes of fibrocartilage and functions to provide congruence of the knee joint, without which the patient is likely to develop arthritis. Endogenous stem/progenitor cells regenerated the knee meniscus upon spatially released human connective tissue growth factor (CTGF) and transforming growth factor-β3 (TGFβ3) from a three-dimensional (3D)-printed biomaterial, enabling functional knee recovery. Sequentially…. ...
The knee meniscus exhibits extensive spatial variations in native healing capacity, biochemical composition, and cell morphology that suggest the existence of distinct phenotypes for meniscus cells. Constitutive gene expression levels of appropriate extracellular matrix proteins may serve as useful molecular markers of cellular phenotypes; however, relatively little is known of variations in the gene expression for meniscus cells of different regions of the tissue. The objective of the present study was to evaluate constitutive differences between radial inner and outer regions in gene expression for extracellular matrix proteins relevant to the meniscus. A secondary objective was to determine if these region-specific differences in gene expression are maintained after periods of monolayer culture. The innermost regions of the meniscus were found to constitutively express higher mRNA levels for proteins highly expressed in articular cartilage, including aggrecan, type 11 collagen, and NOS2. In ...
They are round structures with outer walls that consist of cartilage rings, similar to those of a tree trunk, with a soft jelly-like interior. The outer wall is called the annulus fibrosus and the inner substance is the nucleus pulposus.

It also needs the discs as shock absorbers to protect and shield these nerves from jolts and stress ...

The Triangular fibrocartilage complex (TFCC) is formed by the triangular fibrocartilage discus (TFC), the radioulnar ligaments (RULs) and the ulnocarpal ligaments (UCLs). The TFC is an articular discus that lies on the pole of the distal ulna. It has a triangular shape and a biconcave body; the periphery is thicker than its center. The central portion of the TFC is thin and consists of chondroid fibrocartilage; this type of tissue is often seen in structures that can bear compressive loads. This central area is often so thin that it is translucent and in some cases it is even absent. The peripheral portion of the TFC is well vascularised, while the central portion has no blood supply. This discus is attached by thick tissue to the base of the ulnar styloid and by thinner tissue to the edge of the radius just proximal to the radiocarpal articular surface. The RULs are the principal stabilizers of the distal radioulnar joint (DRUJ). There are two RULs, the palmar and dorsal radioulnar ...

The present disclosure is directed to methods for relieving pain associated with an intervertebral disc having a disc nucleus pulposus and an outer annulus fibrosus surrounding the nucleus pulposus. The method includes the steps of providing an elongated thermal or electromagnetic probe member having a flexible guidable region adjacent the distal end thereof; introducing the flexible guidable region of the probe into the annulus fibrosus of the intervertebral disc; and supplying thermal or electromagnetic energy, from an energy source, to heat or induce an electromagnetic field adjacent to the annulus fibrosus sufficient to produce a thermal or electromagnetic effect on the intervertebral disc. The flexible guidable region of the probe may be introduced at a location which is in relative close proximity to the region of intervertebral disc to be thermally or electromagnetically treated.
Spinal Intervertebral Disk Replacement Material for Nucleus Pulposus and Production Method Thereof - To provide a spinal intervertebral disk replacement material for nucleus pulposus which is relatively superior in load resistance that causes smaller damage of the anulus fibrosus by insertion during operation, remains in the anulus fibrosus stably after operation, and also allows prevention of the damage of the vertebral body cartilage endplate and the anulus fibrosus surrounding the prosthetic portion by sliding, and a production method thereof. The present invention relates to a spinal intervertebral disk replacement material for nucleus pulposus, comprising a dry polyvinylalcohol gel having a percentage of saturated water content of 18 to 50 wt % that changes its shape at a shape deformation rate of 150 vol % or more by water absorption. The present invention also relates to a method of producing the spinal intervertebral disk replacement material for nucleus pulposus above, comprising a step ...
Disc degeneration can be graded reliably on routine T2-weighted magnetic resonance images using the grading system and algorithm presented in this investigation.
Degeneration of the intervertebral disc (IVD) is characterized by marked degradation and restructuring of the annulus fibrosus (AF). Although several matrix metalloproteinases (MMPs) have been found to be more prevalent in degenerate discs, their coordination and function within the context of the disease process are still not well understood. In this study, we sought to determine whether MMP-2 is associated with degenerative changes in the AF and to identify the manner by which AF cells use MMP-2. Two established animal models of disc degeneration, static compression and transannular needle puncture of rodent caudal discs, were examined for MMP-2 immunopositivity. With lentiviral transduction of an shRNA expression cassette, we screened and identified an effective shRNA sequence for generating stable RNA interference to silence MMP-2 expression in primary rat AF cells. Gelatin films were used to compare gelatinase activity and spatial patterns of degradation between transduced cells, and both
The intervertebral disc is a structure made up of two parts that sits between the bones of the spine, or vertebrae, and acts as a sort of shock absorber. The two parts of the disc are the anulus fibrosus, a ligament, and the nucleus pulposus, a jelly like substance. The disc is, almost literally, formed like a jelly doughnut with the ligament on the outside and the jelly in the center.. Because the nucleus has a very high water content, it cant be compressed but, rather, any pressure placed on it is redistributed, evenly, around the interior of the ligamentous anulus fibrosus. This is how it redistributes and diffuses compressive energy to act as a shock absorber.. In some breeds of dogs, though, the nucleus pulposus isnt normal. These dogs are called chondrodystrophic or hypochondroplastic. Several breeds are predisposed to this condition and, therefore, to intervertebral disc disease. This includes the dachshund, poodle, basset hound, and more. When the nucleus pulposus degenerates in ...
Continued From Above... Each intervertebral disk is composed of a band of fibrous fibrocartilage (anulus fibrosus) that surrounds a gelatinous core, called the nucleus pulposus. The bodies of adjacent vertebrae are joined on the front surfaces by anterior ligaments and on the back by posterior ligaments. Projecting from the back of each body are two short stalks called pedicles. They form the sides of the vertebral foramen. Two plates (laminae) arise from the pedicles and fuse in the back to become the spinous process. The pedicles, laminae, and spinous process together complete a bony vertebral arch around the vertebral opening, through which the spinal cord passes.. Between the pedicles and laminae of a typical vertebra is a transverse process that projects laterally and toward the back. Various ligaments and muscles are attached to the spinal process and the transverse process. Projecting upward and downward from each vertebral arch are superior and inferior articulating processes. These ...
Fibrocartilaginous embolic myelopathy (FCE) is common in dogs; however, there is conflicting information in the veterinary literature regarding clinical characteristics and data on recovery in severe cases is sparse. A systematic review of canine FCE was performed to delineate the natural history of this disease. 322 previously reported cases and 71 previously unreported cases were identified for inclusion. Source publications were identified via PubMed central search and by references from review articles. Previously unreported cases were identified via computerised medical records search at two veterinary institutions. FCE was most common in middle-aged large breed dogs (30 per cent); however, the miniature schnauzer was the most frequently reported individual breed and small breeds comprised 24 per cent of all reported cases. The most common neuroanatomical localisation was a T3-L3 myelopathy (33.1 per cent). Prognosis for recovery of ambulation was good to excellent with 85 per cent of cases ...

But, when the damage increases and the chondral defect reaches the subchondral bone, the blood supply in the bone starts a healing process in the defect. Scar tissue made up of a type of cartilage called fibrocartilage is then formed. Although fibrocartilage is able to fill in articular cartilage defects its structure is significantly different to that of hyaline cartilage; it is much denser and it doesnt withstand the demands of everyday activities as much as hyaline cartilage. It is therefore at a higher risk of breaking down. ...
Meniscus Tear Shapes:. The pattern of your meniscus tear is important because it will determine the type of treatment you receive (some tears will heal on their own, some can be treated surgically and some can�t be fixed). Tears come in many shapes and sizes however there are 3 basic shapes for all meniscal tears: longitudinal, horizontal and radial. If these tears are not treated, they may become more damaged and develop a displaced tear (moving flap of meniscus). Complex tears are a combination of these basic shapes and include more than one pattern.. A Longitudinal meniscus tear (circumferential tear)extends along the length of your meniscus and does not go all the way through. This tear divides your meniscus into an inner and outer section; however the tear generally never touches the rim of the meniscus. It tends to be more medial than lateral, and results from repeated movements. It generally starts as a partial tear in the posterior horn, which can sometimes heal on its own. However if ...

Attention!!! Dear Sir or Madam! I would like to inform you of unbelievable efficacy and simplicity of protuberance or herniated pultaceous intervertebral discs repair, which can be monitored by means of magnetic resonance imaging (more). It is important to know that each nerve cell in the nervous system of animal organisms (possibly including plants) has its structural and functional memory, functional in terms of neurophysiology, needed for immanent regulation of bio cybernetic functions, among others to maintain the shape of pultaceous intervertebral discs.. Attention! If objective diagnosis reveals proturbernce or herniated pultaceous intervertebral discs even with compression on the dural sac with pain stenosis. in such case it is advisable to hold skewers between your fingers (choose the sharpest ones), and perpendicularly to the skin perform auto stimulation, triggering stimulus by means of special spatulas which are 7 centimetres wide, beginning with the adams bone, then moving down to ...
An intervertebral prosthesis dimensioned for insertion within an intervertebral space between adjacent vertebrae to replace at least a portion of an intervertebral disc removed therefrom, includes a disc member having sufficient rigidity to support the adjacent vertebrae in spaced relation. The disc member defines a longitudinal axis and a lateral axis transverse to the longitudinal axis. The disc member includes an exterior wall portion having a first slit with a longitudinal component of direction and a second slit with a lateral component of direction. The first and second slits are dimensioned to extend sufficiently within the exterior wall portion and are arranged relative to the longitudinal axis whereby upon insertion of the disc member within the intervertebral space forces exerted on the disc member are transferred along the exterior wall portion as facilitated by the slit arrangement. Preferably, the first slit extends in a general longitudinal direction and the second slit extends in a

High-intensity zone (HIZ) was originally described as a high-intensity signal on T2-weighted magnetic resonance (MR) images, located in the posterior annulus fibrosus, clearly separated from the nucleus pulposus. Among symptomatic patients with low back pain, HIZ is present in 28-59% of cases. In morphologically abnormal discs, high sensitivity and specificity of 81% and 79%, respectively, were reported for HIZs and concordant pain during discography. In contrast, another report indicated low rates. Although most papers reported high sensitivity and specificity for this relationship, it remains controversial ...

A mellkas nagy részét tömegükkel elfoglaló, gyakran benignus jellegű óriástumorok sebészi kezelése különös kihívást jelent. A feladat nagyságát a műtéttechnikai nehézségek, a narkózis vezetése és a postoperativ intenzív ellátás gondjai együttesen adják. Esetünk további sajátosságát az egyébként magától értetődőnek vélhető műtéti javallat végletes ellentmondásossága adja. A 64 éves férfi másfél éve fokozódó, terhelésre jelentkező fulladása ellenére más okból végzett mellkas-röntgenvizsgálatán derült ki a mellkas jobb felének óriási térfoglaló elváltozása. A pulmonológiai kivizsgálás során végzett vastagtű-biopszia solitaer fibrosus pleuratumort igazolt. Az onkológiai konzílium műtéti megoldás mérlegelését javasolta. A beteg állapota a megelőző vizsgálatok közben rohamosan romlott, majd nyugalmi dyspnoe és pitvari fibrilláció miatt intenzív osztályra került, ahol másnap légzési elégtelenség ...

در برخی از مطالعات پیشین تاثیر فشار بر سلول های دیسک بین مهره ای (IVD) در شرایط مختلف بارگذاری دینامیکی مورد بررسی قرار گرفته است. با وجود این، در بسیاری از این مطالعات فشار هیدروستاتیک در مقادیر پایین استفاده شده و مطالعات کمی تاثیر اعمال فشار بالا را با فرکانس های مختلف بر سلول های IVD گزارش نموده اند. در این پژوهش و در ادامه این مطالعات، به منظور بررسی فرضیه وابستگی تحریک سنتز کلاژن در این گروه از سلول ها به فشار هیدروستاتیک اعمالی و فرکانس آن، آزمایش هایی بر مبنای سیستم کشت تک لایه ای طرح ریزی شد. برای اعمال فشار هیدروستاتیکی، سلول های IVD به صورت کشت تک لایه ای
