When normal human keratinocytes are cultured on an appropriate dermal substrate at the air-liquid interface they give rise to a multilayered stratified epidermis closely resembling normal epidermis in vivo. Two skin equivalents, epidermis reconstructed on de-epidermized dermis (REDED) and epidermis on fibroblast-populated collagen matrix (living skin(More)
The heat shock response is a highly conserved reaction common to all cells and organisms. It has been reported that hyperthermic treatment can induce the expression of the heat shock protein (HSP) and can protect cells from ultraviolet (UV) B radiation. In this study, we evaluated the effects of induced HSP70 on resistance to UV radiation. G361 amelanotic(More)
A bidet has been proposed as a replacement for the sitz bath. Like a sitz bath, it brings water into contact with the perineum. However, the high force of water from commercially used electronic bidets may harm the anus. We developed a new electronic bidet and evaluated its effects on anal resting pressure compared with a warm sitz bath. Forty volunteers(More)
Injection of adipose tissue-derived stem cells (ASCs) is a novel method for the treatment of complex perianal fistulas. We aimed to evaluate the safety and efficacy of ASCs in the treatment of complex anal fistulas not associated with Crohn’s disease. A phase II clinical trial was performed comparing two different doses of ASCs (group 1: 1 × 107 cells/mL(More)
