Acellular human gracilis tendons conjugated with gold nanoparticles (AuNP) and hydroxyapatite nanoparticles (nano-HAp) were used as a graft in an anterior cruciate ligament (ACL) reconstruction rabbit model. The ACLs of 11 New Zealand rabbits were reconstructed using grafts conjugated without nanoparticles, with AuNP only, and with both AuNP and nano-HAp. Semi-quantitative histological scoring of bone tunnel portion of grafts was performed after 14 weeks. Bone tunnels were scored for graft degeneration, graft remodeling, percentage of new host fibrous connective, collateral connection, head-to-head connection, graft collagen fiber organization, new host fibrous connective tissue organization, and graft and interface vascularity...

Plants have a remarkable ability to regenerate vascular tissue after damage or wounding. A striking example of this phenomenon is the cutting and rejoining of plants during the process of grafting, which humans have used for millennia. Here, I describe how to graft Arabidopsis seedlings and how to monitor the vascular reconnection process during wound healing using fluorescent dyes and fluorescent proteins. Furthermore, I describe how to visualize xylem formation during graft healing. These techniques are useful for studying how the vascular system regenerates and for better understanding the process of plant grafting...

PURPOSE: After liver transplantation with a small-for-size liver graft or after extensive hepatectomy for liver malignancies or other non malignant conditions with an insufficient liver volume, the survival of patients depends on liver regeneration. This study was carried out in order to create a new porcine model for the study of small-for-size syndrome (SFSS) after extensive hepatectomy. METHODS: In the present study we used 23 domestic Landrace pigs weighing 28...

A spontaneous tendon rupture is a direct consequence of rheumatoid inflammation and can appear without any noticeable impact, often during sleep. The patient then presents with inability to flex or extend metacarpophalageal or interphalangeal joints. Multiple ruptures resulting in impaired function of several fingers can also occur and markedly limit the hand's grip strength. A tear may arise from either mechanical injury to the tendon along its course over bone or connective tissues, or by biochemical action of lysosomal enzymes, released during the inflammation process, on the connective tissue of the tendon...

Tibiofemoral knee dislocation is a rare but serious limb-threatening injury. Without prompt recognition and management, amputation or long-term functional impairment may result. The authors present a case of bilateral sequential knee dislocation, secondary to low-energy trauma, in a patient with Systemic Lupus Erythematosus and antiphospholipid syndrome. Adequate stability was achieved on both occasions by reconstruction of the postero-lateral corner and MCL. During the first reconstruction, ipsi-lateral autograft, as well as hamstring tendons from the contra-lateral side, were used to strengthen the graft...

BACKGROUND: Anterior maxilla is a high esthetic region of the mouth. Some flaps are introduced for bone graft coverage, mainly based on secondary epithelization of connective tissue-periosteal tissues. This article evaluates the versatility of a new mucoperiosteal flap for reproducible coverage in anterior maxilla. METHODS: In 5 mongrel dogs a 5 mm width mucosal defect in labial mucosa was created after extraction of upper jaw incisors. Nasopalatine island advancement flap was used for mucosal replacement...

The present report describes the planning and surgery as well as pitfalls and management of a patient with a near total mandibular avulsion injury that was rehabilitated using three-dimensional (3D) laser printing of a titanium lower jaw. Laser-sintering involves zapping layers of powdered metal to recreate a 3D implantable skeletal defect. The process involves using either mirror imaging of the unaffected side or using archival image database of healthy individuals. A 25-year-old man presented with a gunshot injury that left him with a near total avulsed mandible...

The purpose of this study is to investigate the potential of the local administration of different doses of rosuvastatin (RSV) on autogenous grafted critical-sized cortical bone defects. Twenty-four rats were divided into 3 groups: Group C (control), Group RSV-0.1, and Group RSV-1. A 5-mm diameter critical-size defect was created in the calvarium of each animal. In Group C, the defect was filled by autogenous graft and sterile saline-treated absorbable collagen sponge (ACS) was applied. Defects in the experimental groups (groups RSV-0...

Facial peri-implant mucosal recessions represent an increasing complication in implant dentistry and may negatively affect the esthetic outcome and patient satisfaction. The aim of the present paper is to provide a review on the potential causes of facial peri-implant mucosal recessions and to provide a rationale for treatment along with possible treatment options. The available data indicate that soft tissue augmentation around dental implants is possible, but at present there is no evidence demonstrating that the augmented soft tissues are able to influence the peri-implant bone levels (e...

Anterior cruciate ligament (ACL) is the most frequently torn ligament in the knee, and complete healing is unlikely due to lack of vascularization. Current approaches for the treatment of ACL injuries include surgical interventions and grafting, however recent reports show that surgeries have 94% recurrency, and that repaired tissues are biomechanically inferior to the native tissue. These necessitate the need for new strategies for scar-free repair/regeneration of ACL injuries. Polycaprolactone (PCL) is a biodegradable and biocompatible synthetic polymer, which has been widely used in the connective tissue repair/regeneration attempts...

For ideal implant rehabilitation, an adequate bone volume, optical implant position, and stable and healthy soft tissue are required. The reduction of alveolar bone and changes in its morphology subsequent to tooth extraction will result in insufficient amount of bone and adversely affect the ability to optimally place dental implants in edentulous sites. Preservation of alveolar bone volume through ridge preservation has been demonstrated to reduce the vertical and horizontal contraction of the alveolar bone crest after tooth extraction and reduce the need for additional bone augmentation procedures during implant placement...

When wounding or grafting interrupts the original connection of plant tissue, cell proliferation is induced and the divided tissue is reunited. Previous studies suggested that gibberellin derived from the cotyledon is required for tissue reunion in cucumber and tomato incised hypocotyls, and tissue reunion of Arabidopsis incised flowering stems is controlled by auxin. Differences in the hormone requirements of the tissue reunion process between Arabidopsis and cucumber might be due to differences in organs or species...

PURPOSE: The present study was undertaken to evaluate the healing pattern of xenogenic demineralized dentin onlay grafts in comparison with autogenous bone grafts to the rabbit tibia. MATERIAL AND METHODS: Eight 6-month-old New Zealand male rabbits were used in the experiments. Standardized sized dentin blocks from human premolars and similar autogenous bone blocks harvested from tibia were grafted as onlay blocks on each tibia (n = 8 × 2). All animals were killed after a healing period of 12 weeks...

A xenogeneic collagen matrix recently has been suggested as an alternative to connective tissue graft for the treatment of gingival recession. The matrix avoids the second surgical site, and as a consequence could decrease surgical morbidity. This new matrix was used in various clinical situations and compared to connective tissue graft (CTG) in a split-mouth design case series. A total of 17 recessions were treated with a coronally advanced flap, 9 with CTG, and 8 with the matrix. Mean recession reduction was 2...

Localized ridge resorption, the consequence of socket collapse, following tooth extraction in the anterior maxilla can adversely affect esthetics, function, and future implant placement. Immediate grafting of extraction sockets may help preserve natural ridge contours, but a lack of available soft tissue can compromise the final esthetic outcome. The presented modified rotated palatal pedicle connective tissue flap is a useful technique for simultaneous soft tissue coverage and augmentation of grafted sockets to improve esthetic outcome...

Subepithelial connective tissue graft (SCTG) is considered the gold standard for treatment of gingival recessions. For ethical reasons, most studies report only clinical and not histologic results. A 20-year-old woman presenting with a localized gingival recession of 5 mm in the mandibular left central incisor was treated with SCTG. According to the initial treatment plan, the tooth was extracted 11 months later and a histologic study was performed, revealing new attachment of connective tissue with collagen fibers that were directly inserted in a perpendicular way into dentin areas and new cement areas (1...

BACKGROUND: Although there are many surgical treatments for covering the skin defect of the fore-mid foot, how to reconstruct the weight-bearing region remains a challenge. The weight-bearing region of the sole needs to withstand the pressure and shearing stresses of walking, so the plantar skin is anatomically different from other skins in the areas of texture, thickness, subcutaneous tissue, etc. Medial plantar flaps that are harvested from the instep region are regarded as the first choice for weight-bearing region reconstruction because of their excellent functional and aesthetic long-term result...

BACKGROUND: In this study, we aimed to clarify both systemic and local prognosis after surgical interventions for critical limb ischaemia (CLI) due to vasculitis or connective tissue related disease, and to search for any risk factors that can worsen the prognosis. METHODS: One hundred and ninety three patients that underwent surgical interventions for CLI between 2005 and 2014 were followed up for a median of 2.7 years. The patients were grouped into a group with vasculitis or connective tissue related disease (V) or with atherosclerosis (control: C)...
