Scalp as a donor site in children: Is it really the best option?
… of hair is often used as a preferential donor site for small burns. Major reasons cited are that the donor site is hidden from view (covered by hair), rapidly epithelializes with minimal scarring and provides a relatively large surface area. The author postulates that the type of hair …

Microvascular Free Tissue Transfer of the Rectus Abdominis Muscle in Dogs
Objective - To assess donor site morbidity and survival of the rectus abdominis muscle with an overlying skin graft after free tissue transfer to a medial femorotibial defect in dogs. Study Design - Experimental study Sample Population: Phase one - six canine cadavers / Phase two - seven adult …

Treatment of enchondroma of hand using calcium sulfate and autobone grafting
… to harvest from the iliac crest, and there is donor-site morbidity such as pain and possible infection. Therefore, we studied the efficacy of injectable calcium sulfate as bone substitute and compared the results with autobone grafting. MATERIAL & METHOD: Thirty six patients with solitary …

The biochemical and molecular basis of Hypoxanthine-guanine phosphoribosyltransferase deficiency
… within. intron 6 which created a new splice donor site. The new splice donor site in concert with a cryptic splice acceptor resulted in the creation of a new exon. A deletion of exons 2, 3 and 4 in another patient was found to lead to the alternative splicing of exon 5. These unusual splice …

Alternative expression forms of the bovine αₛ₁-casein gene
… mutation at position +6 in the intron 4 splice donor site is responsible for this skipping (Mohr et al. 1994). The current investigation initially focused on the genetic aetiology of variant A animals in an New Zealand herd; it was found that a single base (adenine) deletion, which is different …

Functional Status of the Donor Limb of Anterolateral Thigh Flap
… In the present study, we prospectively evaluated donor extremity function and investigated the objective functional morbidity of the donor site. We performed a prospective study on 14 cases of head and neck defect reconstruction using free ALT flap at Ajou university hospital between September …

In vitro and in vivo assessments of PCL-TCP composites for bone tissue engineering
… poses no issues of rejection but will result in donor site morbidity and is limited by defect size. Allografts and xenografts are not as popular due to the increased risk of disease transmission, high cost and graft rejection. Shortcomings of current bone grafts motivate researchers to look into …

Design of a novel anterior cruciate ligament prosthesis
… which, however, result in considerable donor site morbidity. An ideal solution would be to use effective, off-the-shelf permanent prostheses: however, all such devices proposed to date have proved highly disappointing, because of poor long term stability and biocompatibility, and …

Cloning and regulation of rat and Xenopus laevis hepatic 3-hydroxy-3-methylglutaryl Coenzyme A reductase
… animals are transcribed from multiple initiation sites. Rat reductase RNA precursor, like the human precursor, is processed at a single donor site to excise the first intron, producing only one class of mRNA equivalent to hamster class I reductase mRNA. Comparison of the amino acid sequences of …

Polypyrrole : an interactive substrate for bone regeneration
… of bone repair rely on autografts (bone from a donor site) and allografts (bone from human cadaver). However, these methods are plagued with disadvantages. There is a clear and urgent need to provide alternatives for regenerating and repairing bone. Bone is known to be one of the many connective …

Long-term osteointegration of BMP-2 eluting hydroxyapatite scaffolds for bone tissue engineering
… bone grafting. Potential limitations, such as donor site morbidity, make the development of synthetic implants with similar success to current techniques an attractive alternative for the repair of these structural defecits. Due to its chemical similarity, porous hydroxyapatite (HA) remains a …

The isolation and characterization of a P. Angulosus homeobox
… the Antp (Hoxl.l) subclass (table 1.1). A splice donor site was identified 23 bp upstream of the homeobox and the observation confirmed by RNAase mapping. PaHboxl is situated in a genomic area showing a significantly higher degree of restriction fragment polymorphism than expected. This was shown …

Evaluation of biocompatible osteoconductive polymer (BOP) as an osteconductive implant
… to the proximal humerus in 7 dogs. Surgery sites were evaluated radiographically at 4 week intervals, and histologically 4, 8, 16, and 24 weeks postoperatively. Radiographic signs of bone healing were not observed in defects receiving BOP fiber. Control defects had radiographic signs of …

Osteogenic Scaffolds for Enhanced Graft-Bone Integration in Ligament Tissue Engineering
… reconstruction surgery, it is associated with donor site morbidity and a decrease in mechanical strength at the donor site. The use of allogenic grafts instead of autografts introduces the risk of disease transmission. Furthermore, integration of soft tissue grafts (e.g., hamstring tendon) to …

Microvascular free tissue transfer for the head and neck reconstructive in a resource-limited setting
… (including flap and systemic complications, donor site morbidity, haematomas as well as returns to theatre). Results: Over a 36-month period, 109 flaps for head and neck reconstruction were performed. The main indication for surgery was squamous cell carcinoma of the oral cavity. The mean …

Supercritical carbon dioxide-processed resorbable polymer nanocomposites for bone graft substitute applications
… spine fusion, their disadvantages, which include donor site morbidity and finite supply have stimulated research and development of novel bone graft substitute materials. Among the most promising candidate materials are resorbable polymers, composed of lactic and/or glycolic acid. While the …

THE ROLE OF INNERVATION IN ENGINEERED MUSCLE
… autologous grafts that require multiple surgical sites, introduce risks of donor-site morbidity, and often fail to fully restore complex muscle architecture, vascularization, and innervation. No available therapy reliably reestablishes both the structural integrity and functional capacity of lost …

Photsluminescence of ZnO: Radioactive ion-implantation and transition metal defects
… eV was shown to be due to recombination at a Ga donor site, while a feature at 3.3225 eV was shown to follow the concentration of the daughter product Ge. A broad red band was found to grow in samples implanted with 72zn. This is believed to be a damage related band, created by the high recoil …

Continuous High-Pressure Negative Suction Drain: New Powerful Tool for Closed Wound Management: Clinical Experience
… time of the drain in the latissimus dorsi donor site was significantly reduced in comparison with the authors’ previous data (P = 0.047). The volume of drainage and hospitalization period were also reduced; however, these were not statistically significant. The dead space with continuous …
