BACKGROUND Photodamaged skin is characterized not only by rhytides, but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, telangiectasias, laxity, and enlarged pores. There is growing interest in the development of noninvasive methods to treat photodamaged skin. Skin photorejuvenation is the visible improvement of(More)
BACKGROUND The authors previously reported their experience achieving non-ablative skin enhancement with serial, full-face, intense pulsed light treatments in a large series of patients. A new method for skin renewal electro-optical synergy (ELOS), which combines intense pulsed optical energy and conducted bipolar radiofrequency (RF) energy into a single(More)
This multi-center study evaluating the role of Intense Pulsed Light (IPL) in the non-ablative rejuvenation of Type I and Type II photoaged skin study was conducted in order to evaluate the clinical efficacy and safety of using IPL in treating clinical indications associated with photoaged skin. Ninety-three patients of Fitzpatrick skin phenotypes I-III,(More)
The Sphygmetrics SR-2 Automatic Blood Pressure Recorder uses an infrasonic technique for detecting artery wall motion to estimate systemic arterial pressure and produces a permanent record of the results. It therefore is potentially useful in reducing observer bias in epidemiologic studies of blood pressure (BP). Two blood pressures were recorded in 21 men(More)
Studies in model organisms suggest that aged cells can be functionally rejuvenated, but whether this concept applies to human skin is unclear. Here we apply 3'-end sequencing for expression quantification ("3-seq") to discover the gene expression program associated with human photoaging and intrinsic skin aging (collectively termed "skin aging"), and the(More)
BACKGROUND AND OBJECTIVE A new 3-step protocol using broadband light allows patients with moderate to severe in ammatory acne to avoid potential side effects of systemic acne treatments and the risks and uncertainties associated with laser and light treatments to date. The protocol also addresses acne scarring and, with appropriate modi cations, all skin(More)
We assessed several modifications of thin-layer chromatography for evaluation of amniotic fluid lecithin/sphingomyelin ratios. For a procedure which is reliable, economical, and easy to perform, we preferred laboratory-prepared plates using SI-LICAR TLC-7GF. For spot detection, we preferred the iodine vapor method.
Flocculation of yeast cells is an important phenomenon that often occurs in beverage production and applications of white biotechnology. In this paper, a novel model for cell movement and cell-cell interaction to simulate yeast cell flocculation is presented. To simulate this process with acceptable runtimes, a GPU implementation based on OpenCL and Java is(More)
