Several clinical research studies have demonstrated that chronic cutaneous wounds can be treated with hair follicle grafts. However, the clinical outcomes of hair follicle grafting compared to split-thickness skin grafting have not been examined. This study sought to compare the clinical outcomes of patients with chronic wounds following hair follicle therapy and split-thickness skin graft ther...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

background: keratinocyte stem cell is one of the adult stem cells that inhabits the skin and contributes to skin function and renewal. adult stem cells are best defined by their capacity to self-renew, and to maintain tissue function for a long period of time. these findings indicate the importance of these cells for clinical applications including regenerative medicine, tissue engineering and ...

BACKGROUND: Teat lacerations are serious injuries thatendanger the survival of a cow within the herd. In excessivelacerations, the wound should be left to heal by second intentionhealing process. However, tissue contraction during healing canchange the alignment of the teat, creating problems for machinemilking. OBJECTIVES: The purpose of the present study was toevaluate the transplantation of ...

A dry-land winter training programme for dinghy-sailors is described. Individual elements include circuit training, specific exercises for muscle strength and endurance, and distance running. Ten international-class sailors followed a progressive regimen of this type for 14 weeks after completion of the 1973 season. Excess weight and skinfold thicknesses were reduced, while muscle strength, end...

Microdialysis is a method by which compounds can be studied in the extracellular space in skin, in vivo. The microdialysis probe is inserted in the dermis using a guide cannula. It is expected that intradermal oedema associated with insertion trauma as well as the probe depth can influence the results of microdialysis studies. The aim of the present study was to assess the effects of insertion ...

Skin is the outermost layer of the human body which regulates the body temperature and protects the body from abrasion and water loss. The Young’s Modulus of skin is measured as a ratio of the stress applied to the skin in vitro or in vivo over the skin deformation. Skin is found to be highly anisotropic and Young’s Modulus is found to be dependent on orientation with respect to Langer’s lines,...

BACKGROUND The formation of free radicals in human skin by solar ultraviolet radiation is considered to be the main reason for extrinsic skin aging. The antioxidants in human tissue represent an efficient protection system against the destructive action of these reactive free radicals. In this study, the parameters of the skin, epidermal thickness, stratum corneum moisture, elasticity and wrink...
