Abstract:
Background: Ten to seventy percent of rotator cuff repairs form a recurrent defect after surgery. The relationship between retraction of the repaired tendon and formation of a recurrent defect is not well defined. Purpose/Hypotheses: To measure the prevalence, timing, and magnitude of tendon retraction after rotator cuff repair and correlate these outcomes with formation of a full-thickness recurrent tendon defect on magnetic resonance imaging, as well as clinical outcomes. We hypothesized that (1) tendon retraction is a common phenomenon, although not always associated with a recurrent defect

Abstract:
AbstractAtrophic scars may be defined as depressive areas on the skin, due to a defect of fatty tissue under the skin. This situation may lead to adherence to the depth (fascia, bone, tendon) to be a source of functional impairment. Most of the atrophic scars are secondary to acne localized over the face. Multiple techniques were proposed to restore the volume and uniformize the surface, like laser, injection of fat, microneedling, microdermabrasion, dermal fillers, and surgical techniques such as subcision and platlet rich plasma (PRP). On the basis of level 1 evidence currently available, it appears that PRP can improve the quality of atrophic acne scars treated with ablative fractional CO2 laser and decrease the duration of laser-related side effects including edema and erythema (Goutos). Regenerative surgery, including fat harvesting, centrifugation, and isolation of adipocyte stem cells, has been promoted since years and should be repeated when injected fat progressive crush is observed. The clinical case presented here is a paraplegic patient presenting a pressure sore in the left ischiatic area. The flap was successful but the depth of the transplanted fatty tissue was decreasing after some years. A first fat injection was programmed.

Abstract:
Abstract The year 1968 has a special meaning in some parts of the world, but other regions do not attach as much importance to it. While the view from Europe tends to assert the existence of a “global 1968,” the timeline may look quite different from another vantage point. This chapter addresses “1968 and beyond” or the “long 1960s,” as the period is often referred to, as a time of global transformations, but with particular local manifestations in terms of ideological underpinnings and legitimations for (violent) action. Israel’s defeat of Arab armies and Indonesia’s tragic events of the 1960s paved the way for a gradual strengthening of various Islamic missionary and activist movements that spread across both regions and gained huge mobilizing momentum subsequently. This period had vast repercussions for decades to come (e.g. in terms of “Islamization” in many countries around the globe).

Abstract:
Examples of intrinsic and extrinsic point defects are discussed. Models of point defects in a continuum as misfitting spheres are solved for rigid and deformablemisfitting spheres. Free surfaces alter significantly the formation volume of a point defect even when the point defect is far from any free surface. Many point defects have non-sperical symmetry, and it is then better to consider defect forces exerted by the point defect on neighbouring atoms. Defect forces capture the symmetry of the point defect in its local environment. Interaction energies between point defects and between point defects and other sources of stress are expressed conveniently and with physical transparency in terms of dipole, quadrupole etc. tensors of point defects and derivatives of the Green’s function. The dipole tensor is experimentally measurable through the lambda-tensor, which measures the derivative of the macroscopic strain of a crystal with concentration of the point defect.

Abstract:
Normal physiologic mechanisms of the upper eyelid are essential for preservation of the eye. Normal function and good cosmesis usually go hand in hand, but preservation of function is the more important of the two priorities. The general considerations in choosing a reconstruction technique include the restoration of: 1. A smooth conjunctival surface to line the eyelid and protect the cornea 2. Structural support of the tarsal plate 3. A smooth, nonabrasive lid margin 4. Normal vertical eyelid movement without ptosis or lagophthalmos 5. Normal horizontal tension with normal medial and lateral canthal tendon positions To cover small defects, the conjunctival lining may be rotated or advanced. For larger defects, the lining may be replaced with a buccal mucous membrane graft or a contralateral conjunctival graft. The tarsal plate usually requires 4 mm of vertical height to provide adequate eyelid support. If the 4 mm is unavailable, it may be replaced with lower lid tarsus, a free tarsal graft from the opposite lid, a free cartilage graft, a polytetrafluoroethylene graft, or a preserved sclera graft. The eyelid margin must be free of trichiasis or surface epithelium, which might abrade the cornea. When levator function is preserved following traumatic or surgical defects of the eyelid, ptosis can usually be avoided or corrected. The levator aponeurosis separates the orbital and palpebral portions of the lacrimal gland, and lacrimal tissue should be preserved when dissecting in the lateral canthal, lateral levator, and lateral anterior orbital areas. Lagophthalmos of the upper eyelid is usually due either to adhesion of the orbital septum to the tarsal plate or to external vertical skin shortage. Proper horizontal tension can be achieved by measuring full-thickness defects while gently pulling the edges of the defect toward each other. Careful measurement reduces the risk of excessive or deficient horizontal length following reconstruction. Skin grafts in the upper eyelids should be covered with a moderate pressure dressing for 4 to 6 days to prevent buckling or subgraft hematoma. Full-thickness skin grafts are preferred to split-thickness grafts for optimal tissue match and coloration. Upper eyelid sutures may be permanent or absorbable. Most external permanent sutures are 7-0 caliber.

Abstract:
This final chapter introduces a few tissue engineering systems that either have been used clinically or are rapidly approaching clinical use for cartilage, skin, and nerve repair. Some of the elements of each tissue engineering system are presented, together with references to the primary literature. The first example involves engineering of a tissue with an important mechanical function: cartilage. The general approach described for cartilage has been attempted in other structural tissues such as bone, tendon, and skin; there are important common elements among these tissue engineering systems. One common underlying theme, which is emphasized in the first example, is the use of a material as a scaffold for the ingrowth, proliferation, and function of cells, which differentiate into mature functional cells. After being introduced to this first example and provided with an outline of some experimental results, the reader is then presented with a series of questions: some are intended to stimulate discussion in the classroom, while others can be used as homework assignments or as the basis for independent projects. The main objective of these exercises is to assimilate information from previous chapters and apply it in a situation with clinical application: cartilage tissue engineering. The second and third examples involve tissue-engineered skin and repair of nerves lost to disease or trauma. No questions are provided with these examples, but the reader is encouraged to identify the connections to material in the preceding chapters. One of the first tissue engineering products available to patients is Carticel1®, which uses autologous cultured chondrocytes for the repair of cartilage defects in the femoral condyle (spirally curved prominences on the end of the femur that is involved in the knee joint). The procedure has several phases: first, a pea-sized biopsy of healthy knee cartilage is obtained. This tissue is expanded in vitro to obtain a large number of cultured cells that are all derived from the patient. In a second procedure, a surgeon prepares the transplant site by removing diseased tissue and preparing the defect (in the clinical trials of this product, the defect had a cross-sectional area of &lt;1 to 20 cm2, with 90% of the defects &lt;10 cm2).

Abstract:
Rotator cuff disorders are one of the most common soft tissue injuries of the musculoskeletal system [1], second only to lower back pain presentations in clinical frequency [2]. Surgical repairs of chronic, massive rotator cuff tears are associated with a high rate of complications, typically by full or partial re-rupture of the repair [3,4]. The literature is replete with clinical retrospective studies or evaluation of cadaveric shoulders [5], however these studies do not address the in vivo healing characteristics of a given surgical repair.

Abstract:
The high failure rate of rotator cuff repair is often attributed to the fact that a normal zonal insertion site is not regenerated between tendon and bone. [1,2] Interestingly, a previous study in our laboratory demonstrated that a patellar tendon autograft (PTA) used to repair a central-third patellar tendon (PT) defect also does not regenerate a normal zonal insertion site at 12 weeks following surgery. Therefore, using our model of tendon healing, our objective was to design a biologic augmentation (BA) that could be implemented at the insertion site between tendon and bone to help promote

Abstract:
Non-contact geomagnetic anomaly detection, as one of passive non-destructive testing (NDT) techniques, can be used to locate pipeline defects, while its accuracy is affected by random noise and detection orientation. In order to extract effective geomagnetic anomaly signals of pipeline defects, a method based on empirical mode decomposition (EMD) and magnetic gradient tensor was studied. In order to filter random noise, EMD was performed to self-adaptively decompose magnetic field signals into a series of intrinsic mode functions (IMFs), and then Hurst exponent was implemented to exclude false

The results indicate that the tensile deformation process consists of an elastic and a plastic periods. The atomic configurations change little in elastic period but change obviously in plastic period. The changes of atomic configurations directly determine the corresponding stress-strain relation. The stress increases linearly as strain grows within the process of elastic deformation. The stress fluctuates greatly in plastic pe
