Bone defects in revision hip surgery can be reconstructed with impacted morselized bone grafts. Rinsing these trabecular allografts may enhance graft incorporation by washing out immunogenic factors present in blood, marrow, and fat. However, it has been proposed that impaction of the graft releases biologically active factors, which can provide sufficient activity to stimulate new bone formati...

We developed a repeated sampling bone chamber (RSBC) and tested its suitability for studying various aspects of the bone allograft incorporation process under reproducible nonload-bearing experimental conditions in a large vertebrate. Our chamber is made of commercially pure titanium and is designed to allow bone or tissue ingrowth into a removable hollow inner core. Three chambers per animal w...

Transfer cells (TCs) play important roles in facilitating enhanced rates of nutrient transport at key apoplasmic/symplasmic junctions along the nutrient acquisition and transport pathways in plants. TCs achieve this capacity by developing elaborate wall ingrowth networks which serve to increase plasma membrane surface area thus increasing the cell's surface area-to-volume ratio to achieve incre...

Purpose. To present the clinical and histopathologic correlation of two cases of epithelial downgrowth (EDG) after prior intraocular surgery. Methods. Observational case reports. Results. We present two cases of EDG occurring after intraocular surgery. In both cases, after two anterior chamber injections of 5-fluorouracil (5FU), the area of EDG initially regressed. In Case 1, a limited area of ...

OBJECTIVE To evaluate intraretinal anatomy in patients with exudative age-related macular degeneration (AMD) using high-speed ultrahigh resolution optical coherence tomography (hsUHR-OCT) before and 1 month after intravitreal injection of ranibizumab. DESIGN Retrospective case series. PARTICIPANTS Twelve eyes of 12 patients. METHODS A broad bandwidth superluminescent diode laser light sou...

BACKGROUND To investigate the reasons for postvitrectomy diabetic vitreous hemorrhage (PDVH), and to analyze the time of PDVH onset, the treatment of PDVH, the visual outcome of the treatment, and factors that affect visual acuity after treatment. MATERIALS AND METHODS Overall, 292 eyes from 236 patients with proliferative diabetic retinopathy (PDR) underwent vitrectomy from 2006 to 2010. Fif...

Purpose: To compare postoperative anatomical sclerotomy sites of transconjunctival sutureless vitrectomy (TSV) with conventional 20-gauge vitrectomy Methods: In this prospective, nonrandomized study 30 consecutive patients divided in 2 groups: group I, 15 eyes from 15 patients underwent conventional 20-gauge and group II, 15 eyes from 15 patients underwent TSV (23, 25-gauge) pars plana vitrecto...

1 MODULAR ENDOPROSTHESES AND TENDON-INGROWTH PROSTHESES Osteosarcoma is the most common primary bone tumor of the appendicular skeleton, frequently affecting large breed dogs. While amputation is considered the gold standard for removing the tumor, many owners would prefer a limb-salvage technique and some dogs are not suitable candidates for amputation given co-morbidities such as neurologic d...
