1. Penile skin flap: a versatile substitute for anterior urethral stricture
ABSTRACT Purpose Penile skin flap uretroplasty is a useful technique for a long urethral stricture due to the ample length and surgical handling characteristics. We investigated the surgical technique and initial results of uretroplasty for anterior urethral strictures using a dorsal penile skin flap. Patients and methods From January 2003 to January 201

2. On the Global and Localised Corrosion Behaviour of the AA2524-T3 Aluminium Alloy Used as Aircraft Fuselage Skin
The aim of this work was to study the corrosion process of new aluminium alloy AA2524-T3 (Solution Heat Treated and Cold Worked), which is a promising substitute of the base line AA2024-T3 for aircrafts fabrication, by global and localised techniques in sodium chloride medium (0.05 mol L-1 NaCl). The open circuit potential results revealed a stochastic evolu

3. Sorbitol-Plasticized and Neutralized Chitosan Membranes as Skin Substitutes
Chitosan is soluble in diluted acid solutions and can easily form films by casting. However, residual acid neutralization should be performed for biomedical applications what may compromise physical and mechanical properties of the films. Thus, plasticizers can be added to improve these properties. The aim of this study was to characterize morphological, bar

4. Avaliação de fármacos fotossensíveis derivados da cloro alumínio ftalocianina no tratamento da progressão tumoral em modelo de matriz tridimensional mista / Evaluation of photosensitizers aluminum chloride phthalocyanine derivatives in the treatment of tumor progression in three-dimensional matrix.
Wound healing process can be favored by Low Level Laser Therapy, with the collagen and elastin matrix a dermic substitute described as an appropriate system in tissue engineering and in tridimensional skin systems. With this purpose, a study was elaborated using the system nanoemulsion of aluminium-chloride phthalocyanine (ClAlPc) as photosensitizer in skin

5. Desenvolvimento e caracterização de dispositivo de PLLA/Trietil-Citrato associado à derme suína acelular para reparação de lesões cutâneas / Development and characterization of PLLA/Triethyl citrate device associated to acellular dermal matrix to repair cutanous wounds
One of the challenges of the Tissue Engineering is to promote a better functioning of organs and tissues damaged by diseases or traumas. With target for developing a biphasic device for future regeneration and dermal application in Tissue Engineering and Regenerative Medicine, fibroblasts from VERO cell line were cultivated on a porcine acellular dermal matr

6. Current controversies in reconstructive surgery of the anterior urethra: a clinical overview
We performed an overview of the surgical techniques suggested for the treatment of anterior urethral strictures using MEDLINE. In applying the MEDLINE search, we used the "MeSH" (Medical Subject Heading) and "free text" protocols. The MeSH search was conducted by combining the following terms: "urethral stricture", "flap", "graft", "oral mucosa", "urethropla

7. Adesão, proliferação e genotoxicidade celular de celulose bacteriana modificada por plasma
Bacterial cellulose (BC) has a wide range of potential applications, namely as temporary substitute skin in the treatment of skin wounds, such as burns, ulcers and grafts. Surface properties determine the functional response of cells, an important factor for the successful development of biomaterials. This work evaluates the influence of bacterial cellulose

8. Extração e caracterização de gelatina de pele de tilapia e aplicação como agente encapsulante de oleo de salmão em microparticulas obtidas por coacervação complexa. / Extraction and characterization of fish skin gelatin and application as encapsulate agent of salmon oil in microparticles obtained by complex coacervation.
Two great challenges in the pisciculture production chain are the use of by-products generated during the fish processing and the production of more attractive microparticles for fish larvae feeding. The aim of this work was to extract and to characterize gelatin from tilapia skin to use it as a substitute of mammalian gelatins in the formation of matrix of

9. Surgical treatment of anterior urethral stricture diseases: brief overview
We performed an up-to-date review of the surgical techniques suggested for the treatment of anterior urethral strictures. References for this review were identified by searching PubMed and MEDLINE using the search terms "urethral stricture" or "urethroplasty" from 1995 to 2006. Descriptive statistics of the articles were provided. Meta-analyses or other mult

10. Hidroxiapatita associada à lignina no preenchimento de falha óssea experimental na tíbia de coelhos / Hydroxyapatite associated to lignin in the filling of experimental bone defect in rabbits tibia
The propose of this work was to evaluate synthetic hydroxyapatite with lignin in solid form as substitute in bone regeneration. Twenty rabbits, from New Zealand race, clinically healthy were used. The animals were divided in two groups with 10 animals each one. Group one received hydroxyapatite associated lignin and group two didnt received the implant. Afte

11. Urethroplasty using a bovine pericardium graft: an experimental study using normal urethras from dogs
The use of bovine pericardium as a urethral patch to substitute a ventral segment of canine urethras was studied. Healing, epithelial growth, urethral permeability, fistulas, and calcification were analyzed. Thirty male mongrel dogs of medium and large size underwent resection of a ventral segment of the medial urethra measuring 2.0 x 0.5 cm, which was repla

12. "Desenvolvimento de membranas como composto dermo epidérmicos" / PREPARATION OF MEMBRANES AS DERMAL EPIDERMAL COMPONENT
Neste trabalho foi estudada a formação de membranas para obtenção de compostos dermo-epidérmicos. A porção dérmica foi desenvolvida utilizando-se mistura de polímeros sintéticos, o poli(álcool vinílico) - PVAl ou poli(vinilpirrolidona) PVP, com polímero natural, a quitosana. As membranas foram reticuladas pela radiação g ou glutaraldeído.
