Leptin is a hormone produced by adipose tissue that regulates various physiological processes. Recent studies have shown that the level of circulating leptin is elevated in obese patients and have suggested a relationship between obesity and postoperative lymphedema. However, the mechanisms by which postoperative lymphedema develops in obese patients and the mechanisms by which leptin regulates...

Five hundred specimens (288 genital, 192 dermal, and 20 ocular) were extracted by technologists, and the DNA was assayed by LightCycler PCR (DNA polymerase and thymidine kinase [TK] gene targets) and by conventional tube and shell vial cell culture. One hundred fifty-eight confirmed (by cell culture and TK target PCR) positive and LightCycler-positive specimens were detected during the first 30...

in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

objective(s): with the advent of nanotechnology, significant progress has been made in the area of nanoscale materials such as nanosilver (ag-nps). these nanoparticles have a wide range of applications and been used for antimicrobial purposes for more than a century. however, little attention has been paid to the toxicity of nanosilver wound dressing. this study was designed to investigate the ...

background we present a novel method for augmenting the standard c-v flap used for nipple reconstruction with a free dermal graft which aims to improve the appearance of the nipple reconstruction, decrease loss of projection and improve patient satisfaction overall. methods the surgical technique for performing a free dermal graft augmentation of a cv flap is described. all patients who underwe...

Stylostome and skin inflammatory reaction during feeding of Neotrombicula talmiensis (Schluger, 1955) (Acariformes, Trombiculidae) larvae on the naturally infected host animals – voles Myodes rufocanus Sundevall, 1846 Asian chipmunk Tamias sibiricus (Laxmann, 1769) were studied by histological methods. In addition, in scanning electron microscope (SEM). The apical hypostomal portions form a tem...

conclusions based on the results of the current study, it was concluded that aloe vera, licorice and mint extracts had synergistic effects on the viability of dermal fibroblasts; in addition, the combination of aloe vera and licorice with either henna or myrtle, and aloe vera and mint with either cedar or ginger resulted in synergistic effects on viability of dermal fibroblasts. the third categ...

Background: Risk factors affecting cutaneous melanoma metastasis and prognosis have been actively studied. Previously, we had found that amelanotic mild pigmentation of acral was associated with first distant metastasis, whereas heavy lymph node metastasis. Objective: We aimed to confirm lymphatic proliferation invasion according degree in melanoma, by immunohistochemical stains cell culture. M...

To understand the mechanisms by which 15(S)-hydroxyeicosatetraenoic acid (15(S)-HETE) activates Rac1 in the induction of angiogenesis, we studied the role of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase and αPix. 15(S)-HETE stimulated Rac1 in a sustained manner in human dermal microvascular endothelial cells (HDMVECs). Simvastatin, a potent inhibitor of HMG-CoA reductase, suppresse...

Objective The treatment of laryngotracheal stenosis is a major therapeutic challenge. Various treatments include observation, medical management, and surgical management. The most effective surgical management is resection and reconstruction. To the authors' knowledge, no reports have described the use of xenogenic acellular dermal matrix (ADM) for laryngotracheal stenosis. Methods A 27-year-ol...
