The ampulla ureter and ampulla urogenital ⁄ uriniferous papilla represent differing morphologies of the caudal urogenital ducts in snakes. The ampulla ureter is an enlarged portion of the caudal extremity of the ureter that communicates the cranial regions of the ureter and the ductus deferens ⁄Wolffian duct to the urodaeum. The ampulla urogenital ⁄ uriniferous papilla is an enlarged pouch, dis...

Pollination is an important early step in sexual plant reproduction. In Arabidopsis thaliana, sequential pollination events, from pollen adhesion onto the stigma surface to pollen tube germination and elongation, occur on the stigmatic papilla cells. Following successful completion of these events, the pollen tube penetrates the stigma and finally fertilizes a female gametophyte. The pollinatio...

We compared the ability of three different posterior cruciate ligament (PCL) reconstructions to restore normal anteroposterior laxity to the knee from 0 to 130 degrees of knee flexion. Cadaver knees were tested intact, after PCL rupture or after bone-patellar tendon-bone grafting. Grafts were performed isometrically or with a single bundle representing the anatomical anterior PCL fibre bulk (aP...

BACKGROUND Ulnar collateral ligament reconstruction (UCLR) has become a common procedure performed in overhead-throwing athletes of many athletic levels. PURPOSE/HYPOTHESIS The purpose of this study was to determine whether clinical outcomes and return-to-sport (RTS) rates differ among patients undergoing UCLR based on graft choice, surgical technique, athletic competition level, handedness, ...

STATEMENT OF THE PROBLEM Gingival recession has been considered as the most challenging issue in the field of periodontal plastic surgery. PURPOSE The purpose of this study was to evaluate the clinical efficacy of root coverage procedures by using partial thickness double pedicle graft and compare it with full thickness double pedicle graft. MATERIALS AND METHOD Eight patients, aged 15 to 5...

BACKGROUND High-quality mandibular reconstruction using vascularized free fibular graft is necessary to provide an osseointegrated dental implant and fixed denture. An appropriate crown-implant ratio is needed, and a good match between bones is extremely important. There are no articles describing the analysis and evaluation of both the fibula and mandible in the same patients. METHODS Comput...

BACKGROUND There is significant interest in the restoration of the double-bundle anatomy of the native ACL when performing ACL reconstruction. Possible techniques include those utilizing two separate grafts with independent tunnels and those that attempt to mimic this anatomy with a single graft and fewer tunnels. Many of the latter techniques require specific instrumentation and are technicall...

Background To assess and compare the effectiveness of two surgical procedures (Beagle's technique and modified Beagle's technique) for the reconstruction of the lost interproximal dental papilla. Materials and Methods Twenty sites were selected based on the selection criteria which included patients within the age group of 20-50 years and the presence of Class I and Class II recession of the ...

PURPOSE To evaluate the signal characteristics of the optic papilla (optic nerve head) on routine cranial MR images in patients with clinical evidence of optic papilla elevation caused by high intracranial pressure, and to compare these findings with findings in healthy adult volunteers. METHODS We reviewed retropectively the MR imaging examinations of 15 patients who were referred with objec...
