Optical coherence tomography (OCT) is a non-invasive imaging technique, which has previously demonstrated potential for use in dermatology. The purpose of this study is to demonstrate how improvements in image quality, speed, and functionality enable qualitative and quantitative information to be obtained from in vivo human skin. We developed a portable fiber-optic based OCT imaging device that...

We study different flow control methods on turbulent around a NACA4412 airfoil, using resolved large-eddy simulation (LES). find that changes in total skin friction due to blowing and suction are not very sensitive pressure-gradient conditions nor the Reynolds number. However, boundary-layer thickness, intensity of wall-normal convection, fluctuations much more affected, mostly adverse-pressure...

Neonatal skin suffers a progressive adaptation to the extrauterine environment and special care is needed during this period. This skin is very sensitive, thin and fragile. Immaturity of the epidermal barrier reduces the defense against the excessive proliferation of microbes and makes the skin more vulnerable to trauma and percutaneous drug toxicity. Because of the peculiar characteristics of ...

Abstract Skin-integrated haptic interfaces that can relay a wealth of information from the machine to human are great interest. However, existing devices not yet able produce cues compatible with skin. In this work, we present stretchable soft actuators for feedback, which match perception range, spatial resolution, and stretchability Pressure-amplification structures fabricated using scalable ...

BACKGROUND Approximately, 50% of the population claim to have sensitive skin, which has created an important challenge for dermatologists and the cosmetic industry. This study evaluates the properties of QV Face Rescue Gel (Rescue Gel) that contains a combination of moisturizing and anti-irritant ingredients, and which is used to relieve the symptoms of sensitive facial skin. METHODS The abil...

PURPOSE We previously reported that the skin prick test was sensitive and the serum specific immunoglobulin E test was specific for predicting positive airway responses to house dust mites (HDMs) in patients with asthma. Because the nose and bronchus are one airway, the nasal provocation test would be more specific for predicting the bronchial responses to HDM than the skin test. METHODS The ...

STUDY OBJECTIVE The aim was to evaluate the hypothesis that sunlight exposure leads to the development of gallstones in people with a sun sensitive skin. DESIGN AND SETTING This was a case-control study among 206 white patients referred for an ultrasound examination of the gallbladder. Sunlight exposure and skin sensitivity were retrospectively assessed by a structured questionnaire. The ques...
