Jcl:WistarTGN(ARGHGEN)1Nts rat (Mini rat) is a growth hormone (GH)-deficient transgenic rat. The hair cycle in the dorsal skin of male Mini rats enters a long-lasting telogen phase after eights weeks of age, but depilation can induce a transient hair cycle again. In this study, a time-course profiling of genes expression was done on the dorsal skin of male Mini rats along the progression of dep...

The objective of this work is the investigation of intense pulsed light (IPL) photoepilation using Monte Carlo simulation to model the effect of the output dosimetry with millisecond exposure used by typical commercial IPL systems. The temporal pulse shape is an important parameter, which may affect the biological tissue response in terms of efficacy and adverse reactions. This study investigat...

We present an efficient and improved method for hair removal from dermoscopic images, which is faster and can remove hairs more effectively as compared to the existing and widely used DullRazor(®). To do so, we first detect the predominant orientation of hairs in the image by using Radon transform, followed by filtering the image by Prewitt filters using the orientation of existing hairs. Undes...

BACKGROUND AND OBJECTIVE Based upon the thermal relaxation time of the hair follicle (10-50 ms), most lasers and light devices use relatively long pulse widths for hair removal. This study was conducted to evaluate a shorter pulsed, 0.65 ms Nd:YAG laser for hair removal. METHODS One half of each axilla of six female participants was treated and the other half was monitored as a control. The t...

INTRODUCTION Laser hair removal of blond and white hair is a complicated task with often unsatisfactory results as a result of a lack of laser-absorbing chromophore. In the present study, we investigated if repetitive external application of liposomal melanin (Lipoxome; Dalton Medicare B.V., Zevenbergschen Hoek, The Netherlands) enables removal of blond/white and gray hair with a diode laser. ...

BACKGROUND A variety of lasers and light sources have been used for hair removal. A novel flashlamp-based device, with a mechanism of action mixing a combination of light and heat, has recently become available. OBJECTIVE To assess the efficacy, side effects and long-term results of this new light/heat-based system for photo-epilation. METHODS A total of 21 patients (six male, 15 female), s...

OBJECTIVE To determine the relative importance of different risk factors for the development of surgical-site infections (SSIs) in orthopedic surgery with prosthetic implants. DESIGN In a cohort of 272 patients, the following possible risk factors were studied: age, gender, method of hair removal, duration of operation, surgeon, underlying illness, and nasal carriage of Staphylococcus aureus....

Since ancient Egypt cosmetics have been a part of our life. Cosmetic products appeal to large variety areas ranging from perfume, hair dyes and care products, toothpastes, dermal face-eye make-up materials. contain biological active components. These compounds generally are sensitive parameters such as light, pH, temperature air oxidation they not stable. This also causes unwanted possibilities...

INTRODUCTION Despite the high incidence of polycystic ovary syndrome (PCOS) in women attending for facial hair removal there are few studies looking specifically at this patient group. We carried out a split-face study directly comparing the efficacy of a 3 milliseconds pulse duration alexandrite laser with the Lumina IPL system in 38 women with PCOS. MATERIALS AND METHODS Each patient underw...

Surgical decompression of the greater occipital nerve is used in the treatment of migraine headaches. Generally, hair is removed from the posterior scalp to aid with exposure and minimize interference. The securing of occipital hair with surgical tape and rubber bands instead of preoperative hair removal is a viable alternative. The preservation of hair length can lead to better patient satisfa...
