background platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. the primary objective of this study was to use autologous platelet rich plasma (prp) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. methods in a single cen...

OBJECTIVE New vessel formation is a dynamic process of attachment, detachment, and reattachment of endothelial cells (ECs) and endothelial progenitor cells (EPCs) with each other and with the extracellular matrix (ECM). Integrin-linked kinase (ILK) plays a pivotal role in ECM-mediated signaling. Therefore, we investigated the role of ILK in ECs and EPCs during neovascularization. METHODS AND ...

The aim of this retrospective study was to determine differences between the outcomes of treatment using implant anchorage compared with straight-pull headgear and intermaxillary elastics in bimaxillary protrusion patients. The lateral cephalograms of 28 adult orthodontic patients (3 males and 25 females; age, 24.9 ± 5.0 years) who had an Angle Class I malocclusion with bimaxillary protrusion w...

Cervical cancer and a subset of anogenital and head-and-neck carcinomas are caused by high-risk types of the human papillomavirus (hrHPV). During hrHPV-induced malignant transformation keratinocytes become able to grow anchorage independently, a tumorigenic trait at least partly associated with inactivation of tumor suppressor genes. We used hrHPV-containing keratinocytes to investigate the rol...

Twenty-one anchorage-independent subclones and ten subclones with reduced serum requirements were isolated as single-step mutants spontaneously or after ethylmethanesulfonate or A/-methyl-/V'-nitro-/V-nitrosoguanidine mutagenesis of CHEF/18 diploid Chinese hamster embryo fibroblasts. An chorage-independent mutants retain the high serum require ment and nontransformed morphology typical of CHEF/...

The porcine model is frequently used during development and validation of new spinal devices, because of its likeness to the human spine. These spinal devices are frequently composed of pedicle screws with a reputation for stable fixation but which can suffer pullouts during preclinical implantation on young animals, leading to high morbidity. With a view to identifying the best choices to opti...

OBJECTIVES The aim of this study was to investigate the effects of retraction force and anchorage reinforcement with orthodontic mini implants on occlusal force. MATERIALS AND METHODS A strain gauge was attached to the palatal surface of the maxillary right first molar on an en masse retraction model. RESULTS Occlusal forces were measured from this model, according to different retraction f...

BACKGROUND Stability is determined as one of the requirements in use of Temporary Anchorage Devices (TAD) in orthodontics. Miniscrew has been a widely used Bone Anchor. Compared with mini-implant that necessitates osseointegration; mechanical retention is a determining factor for primary stability of miniscrew. Studies investigated various ways to increase primary stability. The aim of this stu...

Project conducted in cooperation with the U.S. Department of Transportation, Federal Highway Administration, and the Texas Department of Transportation 16. Abstract The findings of a literature review of topics related to the anchorage of headed reinforcement are presented. The topics are grouped in three broad categories: conventional anchorage of reinforcement, anchorage of headed reinforceme...

To determine whether methicillin-resistant Staphylococcus aureus (MRSA) USA300 commonly caused infections among Alaska Natives, we examined clinical MRSA isolates from the Alaska Native Medical Center, Anchorage, during 2000-2006. Among Anchorage-region residents, USA300 was a minor constituent among MRSA isolates in 2000-2003 (11/68, 16%); by 2006, USA300 was the exclusive genotype identified ...
