Introduction: Laser tissue soldering is a new technique for repair of various tissues including the skin, liver, articular cartilage and nerves and is a promising alternative to suture. To overcome the problems of thermal damage to surrounding tissues and low laser penetration depth, some exogenous chromophores such as gold nanoshells, a new class of nanoparticles consisting of a dielectric cor...

This study was conducted to identify some of ante and post-mortem surface defects in Sudanese raw sheep and goat skins and to evaluate the effect of some of these defects on some of the key physical properties of the leather produced. The results indicated that most of the ante-mortem defects disappear during the tannage, re-tannage and finishing operations. However some defects remain visible ...

Strength, stiffness, strain at fracture and moisture content of onion skins were measured after incubation at a range of humidities. Higher relative humidity (RH) resulted in skins which had greater moisture content, were stronger in multi-directional tests and which were less stiff. In uni-directional tests, skins incubated at higher RH had extended more at fracture than those incubated at low...

Four full-thickness skin wounds made in normal mice led to the significant increase in levels of nerve growth factor (NGF) in sera and in wounded skin tissues. Since sialoadenectomy before the wounds inhibited the rise in serum levels of NGF, the NGF may be released from the salivary gland into the blood stream after the wounds. In contrast, the fact that messenger RNA and protein of NGF were d...

Polyurethane/zeolite 13X nanocomposite films were fabricated using solution casting method. The synthesized nanocomposite films were structurally characterized using SEM, TGA and tensile analysis. SEM images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. Better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

Morinda citrifolia (Noni) has been traditionally used for bone and wound healing.   The present study was carried out to investigate the effect of Morinda citrifolia leaves on experimental wounds and lipid peroxide levels in rats. Effect of aqueous extract of leaves of Morinda citrifolia (200 mg/kg) on excision, resutured incision and dead space wound models were studied. Measurement...

BACKGROUND This study describes the use of a bioabsorbable suture for skin suturing during surgery for lateral ray polydactyly followed by favorable postoperative outcome without the need for postoperative suture removal. METHODS A 5-0 Vicryl Rapide suture was used for skin suturing during surgery for lateral ray polydactyly in 9 children (mean age, 12.4 mo). Children were allowed to walk and...
