PURPOSE: The purpose of this study was to examine the effects of a skin barrier cream with moisturization and skin-protectant characteristics for improving the severity of incontinence-associated dermatitis (IAD) pertaining to the skin physiology and appearance. We measured the following outcomes: (1) skin physiological characteristics indicating skin protection and enhancement of the skin's moisture barrier (stratum corneum hydration, dermis hydration level, transepidermal water loss, and skin pH); and (2) changes in skin appearance (the degree of erythema and pigmentation, and the sulcus cutis condition)...

Transdermal protein delivery is a powerful and attractive method for protein therapy and dermal vaccination compared with other administrations. However, this delivery method is restricted by the low permeability of the stratum corneum, a hydrophobic barrier that restricts the entry of hydrophilic molecules such as proteins. In this study, we developed an improved gel patch system carrying ovalbumin and ovalbumin epitope peptide, and then compared their permeability into the skin. First, the gel patch was placed on mouse skin to allow contact with the polymer coated gold nanorods and then irradiated by a continuous-wave laser...

The discovery of beta-adrenergic blocker effects on infantile hemangiomas has affected the choice of treatment in recent years. Oral propranolol is effective in treating infantile hemangiomas, but the risk of systemic side effects remains a concern. Data from literature review reported positive clinical outcomes with no major adverse effects observed in children using topical beta-blocker such as timolol maleate. Topical application of timolol eye drop has been mentioned in few studies, most of which reported that the solution cannot stay on the site of application due to its fluidity...

Accurate in-silico models are required to predict the release of drug molecules through skin in order to supplement the in-vivo experiments for faster development/testing of drugs. The upper most layer of the skin, stratum corneum (SC), offers main resistance for permeation of actives. Most of the SC's molecular level models comprise of cholesterol, and phospholipids only, which is far from the reality. In this study we have implemented a multiscale modelling framework to obtain the release profile of three drugs namely Caffeine, Fentanyl and Naphthol through skin SC...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

INTRODUCTION: Nasolabial cutaneous flaps have been routinely used to reconstruct intraoral defects. The purpose of this study was to study histological changes that may occur in the skin flap as a result of its exposure to a new environment. PATIENTS AND METHODS: Thirteen patients took part in this study. Fusiform tissue specimens were obtained from the intraoral cutaneous portion of the flap. Biopsy specimens were also taken from the skin of nasolabial region and from the buccal mucosa to serve as control...

Occurrence patterns are partly shaped by the affinity of species with habitat conditions. For winged organisms, flight-related attributes are vital for ecological performance. However, due to the different reproductive roles of each sex, we expect divergence in flight energy budget, and consequently different selection responses between sexes. We used tropical frugivorous butterflies as models to investigate coevolution between flight morphology, sex dimorphism and vertical stratification. We studied 94 species of Amazonian fruit-feeing butterflies sampled in seven sites across 3341 ha...

Health-promoting aspects attributed to probiotic microorganisms, including adhesion to intestinal epithelia and modulation of the host mucosal immune system, are mediated by proteins found on the bacterial cell surface. Notably, certain probiotic and commensal bacteria contain a surface (S-) layer as the outermost stratum of the cell wall. S-layers are non-covalently bound semi-porous, crystalline arrays of self-assembling, proteinaceous subunits called S-layer proteins (SLPs). Recent evidence has shown that multiple proteins are non-covalently co-localized within the S-layer, designated S-layer associated proteins (SLAPs)...

Enzymes may offer great potentials in topical pharmaceutical applications provided that treatment conditions are controlled for efficacy and safety. In this study, the effect of alkaline protease produced by recombinant Bacillus subtilis cells on the ex-vivo permeability of rabbit ear skin was investigated under different conditions of enzyme activity (5-60 units) and exposure time (15-60min). Data for transepidermal water loss (TEWL) and permeation of a hydrophilic dye, rhodamine B (Rb), indicated biphasic activity-dependent and exposure time-dependent skin permeability...

Based on the crucial roles of ceramides in skin barrier function, use of ceramides or their structural mimetic compounds, pseudoceramides, as cosmetic ingredients are getting more popular. While currently used pseudoceramides are intended to substitute the structural roles of ceramides in stratum corneum, development of bioactive pseudoceramides has been repeatedly reported. In this study, based on the potential involvement of sphingolipids in hair cycle regulation, we investigated the effects of newly synthesized pseudoceramide, bis-oleamido isopropyl alcohol (BOI), on hair growth using cultured human hair follicles and animal models...

INTRODUCTION: Pre-treatment of the skin to remove scales and crusts prior to photodynamic therapy (PDT) is essential to enhance the uptake of topically applied methyl aminolevulinate (MAL) and to improve treatment efficacy. This study compared the effect of two different skin preparation pads on skin integrity in ex vivo human skin. METHODS: Ex vivo human skin samples from three donors were pre-treated in triplicates with PREPSTER™ (PR) skin preparation pad (6, 8, and 10 passages) or Ambu Unilect™ (A-UN) skin preparation pad (6, 8, and 10 passages)...

In this note, we present a simple mathematical model of drug delivery through transdermal patches by introducing a memory formalism in the classical Fick diffusion equation based on the fractional derivative. This approach is developed in the case of a medicated adhesive patch placed on the skin to deliver a time released dose of medication through the skin towards the bloodstream.The main resistance to drug transport across the skin resides in the diffusion through its outermost layer (the stratum corneum)...

BACKGROUND: It has been reported that drugs which promote the N-Methyl-D-aspartate-type glutamate receptor function by stimulating the glycine modulatory site in the receptor improve negative symptoms and cognitive dysfunction in schizophrenia patients being treated with antipsychotic drugs. METHODS: We performed a placebo-controlled double-blind crossover study involving 41 schizophrenia patients in which D-cycloserine 50 mg/day was added-on, and the influence of the onset age and association with white matter integrity on MR diffusion tensor imaging were investigated for the first time...

Stratum corneum is the primary skin barrier to percutaneous absorption. Since 1980, topical liposomal formulations have been proposed and successfully employed for increasing the drug penetration through the skin. There is no clear consensus on the drug penetration mechanism from topically applied liposomes, despite a vast amount of research. One of the reasons for the ambiguity is that the interactions between the stratum corneum and liposomes are in nanoscale, which makes them difficult to probe. In this study, we employed tip-enhanced Raman scattering (TERS) to gain a better understanding of the interactions between the human stratum corneum and topically applied liposomal system called invasomes...

In this work we report the studies of the effect of temperature on skin components, such as lipids, proteins and water. Modifications of lipids structure induced by increasing temperature (from 20 to 90°C) have been studied using ATR-IR (Attenuated Total Reflectance Infrared) spectroscopy, which is a powerful tool for characterization of the molecular structure and properties of tissues, such as skin. Due to the small depth of penetration (0.6-5.6μm), ATR-IR spectroscopy probes only the outermost layer of the skin, i...

In vivo phototoxicity studies are important to predict drug-induced phototoxicity in humans; however, a standard methodology has not established. To determine differences in sensitivity to drug-induced phototoxicity among various skin sites, we evaluated phototoxic reactions in the back and abdominal skin of female Sprague-Dawley rats orally dosed with phototoxic drugs (pirfenidone, 8-methoxysoraren, doxycycline, and lomefloxacin) or a non-phototoxic drug (gatifloxacin) followed by solar-simulated light irradiation comprising 18J/cm(2) ultraviolet A...

Ablative fractional lasers (AFXL) enhance uptake of therapeutics and this newly emerging field is called laser-assisted drug delivery (LAD). This new science has emerged over the past decade and is finding its way into clinical practice. LAD is poised to change how medicine delivers drugs. Topical and systemic application of pharmaceutical agents for therapeutic effect is an integral part of medicine. With topical therapy, the stratum corneum barrier of the skin impairs the ability of drugs to enter the body...
