Facial rejuvenation procedures can be roughly divided into face lift surgery and nonoperative, less invasive procedures, such as fat grafts, fillers, botulinum toxin injections, thread lifts, or laserbrasion. Face lift surgery or rhytidectomy is the procedure most directly associated with rejuvenation, due to its fundamental ability to restore the anatomical changes caused by aging. Various methods of face lift surgery have been developed over the last hundred years, thanks to advances in the un

In this study, a microfluidic-based physiometer capable of measuring whole blood viscosity, hematocrit, and red blood cell (RBC) deformability on a chip is introduced. The physiometer consists of two major parts: a hydrodynamic component for whole blood viscosity measurement and an electronic component for hematocrit and RBC deformability measurement. In the hydrodynamic component, the whole blood is infused with phosphate buffered saline as a reference fluid for estimation of the whole blood vi

The novel isotropic pitch that exhibits both high solvent solubility (100% soluble in THF) and a high softening point (over 200°C) was successfully synthesized by the bromination of 2-methylnaphthalene followed by dehydrobromination/polymerization and extraction in n-hexane to eliminate lighter constituents. The molecular structure of the pitch was relatively linear with flexible methylene cross-linkages between naphthalene molecules. During bromination, a reaction temperature of 180°C was neces

OBJECTIVE: We describe specific surgical methods for angiosarcoma regarding extent of resection and reconstructive options and assess their effect on patients' prognosis. PATIENTS AND METHODS: We retrospectively examined 14 patients undergoing treatment for angiosarcoma of the scalp at our institute between January 2000 and June 2015. Surgical treatment comprised wide excision of the tumor and reconstruction using a free flap with skin graft. Kaplan-Meier survival analysis was used to assess the

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP), a rare low-grade sarcoma of fibroblast origin, tends to extend in a finger-like fashion beyond macroscopic tumor margins. Therefore, incomplete removal and subsequent recurrence are common. This study aimed to determine the efficacy of wide local excision (WLE) for controlling local recurrence of DFSP. METHODS: The medical records of 90 DFSP patients who received WLE at our hospital between June 1992 and January 2015 were retrospectively review

Barbarians should be divided into three parts at least. In Qin-Han Empire, there were two kinds of borders. One was an outer border which distinguished the Qin-Han and other hostile enemy states. The other was an inner border, within which the native barbarians had lived without being subjugated into empire. In this sense, we should not confuse the barbarians who were already under Han’s control with the others beyond the outer and inner border. Many previous studies claimed the loosened control

BACKGROUND: Extramammary Paget's disease (EMPD) is an intraepithelial carcinoma usually occurring on the skin or mucosa of the perineum. Clinically, it resembles eczema or dermatitis, and misdiagnosis and treatment delays are common. The treatment of choice for EMPD is a wide excision with adequate margins. Wide excision with intraoperative frozen biopsy and Mohs micrographic surgery are common methods; however, these are associated with a high recurrence rate and long operation time, respective
