This article presents a technique for soft tissue reconstruction and covering defects associated with maxillary implant-supported restorations. A pedicle subepithelial connective tissue flap is prepared from the palatal mucosa near the area to be treated and is displaced into the receptor site. The donor site remains primarily covered. An increase in soft tissue volume is achieved at the recept...

The dermal papilla is a discrete group of cells at the base of the hair follicle and is implicated in controlling the hair growth cycle. Early passage dermal papilla cells can induce hair growth in vivo, but, upon further culturing, this property is lost. In order to study the events occurring in hair induction, a representative dermal papilla cell line was required. We have transfected passage...

For anurans, increasing complexity of the inner ear has been correlated with speciation rates. The evolution of a complex amphibian papilla (AP) is thought to have facilitated speciation by extending the range of frequencies over which mating calls may diverge. Although this example has been proposed to represent a key innovation, the mechanism by which the AP is thought to promote speciation m...

Lengthening of a double-looped tendon graft construct used to reconstruct the anterior cruciate ligament (ACL) can result in an increase in anterior knee laxity and affect the stability of the reconstructed knee. Three possible regions where lengthening of the construct can occur are (1) the region of the tibial fixation, (2) the region of the femoral fixation, and (3) the region of the graft b...

OBJECTIVE We recently reported a technique of unilateral double lobar lung transplantation (UDLLT) in a canine model that was associated with satisfactory early pulmonary function. The purpose of the present experimental study was to assess the quality of bronchial healing, complication rates, survival rates and long-term pulmonary function of this new transplantation technique. METHODS Unila...

Nine years after receiving a bone marrow transplant for aplastic anemia, a 14-year-old girl with severe pulmonary disease associated with graft-versus-host disease received a double lung transplant. Subsequent to lung transplant, her lung function improved dramatically (FEV1 increasing from 20 to 73 percent predicted normal, residual volume decreasing from 316 to 130 percent predicted normal va...

Metastatic tumors of the duodenal papilla (ampulla of Vater) are rare. The images here are from a middle-aged gentleman with progressive cholestatic jaundice and recurrent cholangitis, with a past history of nephrectomy for renal cell carcinoma (RCC) 6 years earlier. Endoscopy revealed a bulky duodenal papilla, and the biopsy showed features consistent with RCC (Figs. 1 and 2). Metastatic tumor...

The main strategy in experimental and clinical neural transplantation in Parkinson's disease has been to place fetal nigral grafts not in their ontogenic site (substantia nigra) but in their target area (striatum). The reason for this ectopic placement is the apparent inability of nigral grafts placed in the ventral mesencephalon (VM) of the adult host to grow axons for long distances that are ...

Background and aims Using free quadriceps tendon graft for anterior cruciate ligament (ACL) reconstruction has become more popular in the last years due to the low morbidity at the harvest site and biomechanical and structural properties similar to other types of graft (hamstring and patellar tendons). As long as the tibial tunnel fixation with interference screws is considered the standard fix...

PURPOSE The purpose of this study was to evaluate the clinical efficacy of enhancing deficient interdental papilla with hyaluronic acid gel injection by assessing the radiographic anatomical factors affecting the reconstruction of the interdental papilla. METHODS Fifty-seven treated sites from 13 patients (6 males and 7 females) were included. Patients had papillary deficiency in the upper an...
