Skin stretching by a balloon tissue expander: Interplay between contact mechanics and skin growth

The interplay between morphogens and tissue growth.

Morphogens are conserved, secreted signalling molecules that regulate the size, shape and patterning of animal tissues and organs. Recent experimental evidence has emphasized the fundamental role of tissue growth in expanding the expression domains of morphogens and their target genes, in generating morphogen gradients and in modulating the response of cells to morphogens. Moreover, the classic...

Skin-to-Skin Contact After Cesarean Delivery

the use of tissue expander in repairing skin and hair lesions of the head

of 14 cases who underwent this operation only in one of them because of infection in operation site, we had to extract the expander. also, in the first day of the operation that we injected serum inside the expander of two other patients, the wound opened up and the expander appeared and came out automatically. the remaining ten patients have tolerated the operation after treatment period witho...

Stretching skin: The physiological limit and beyond.

The goal of this manuscript is to establish a novel computational model for skin to characterize its constitutive behavior when stretched within and beyond its physiological limits. Within the physiological regime, skin displays a reversible, highly nonlinear, stretch locking, and anisotropic behavior. We model these characteristics using a transversely isotropic chain network model composed of...

The Effect of Postpartum Mother–Infant Skin-to-Skin Contact on Exclusive Breastfeeding In neonatal period: A Randomized Controlled Trial

Background: The rate of exclusive breast feeding is low in many societies and has diminished in recent years in Iran. This study was conducted to determine the effects of postpartum mother–infant skin-to-skin contact on exclusive breastfeeding in neonatal period. Materials and Methods: This was a randomized control trial. 114 healthy primiparous mothers and their neonates were recruited in Om-...
