Intradermal DNA vaccination is a promising method of immunization that overcomes some practical drawbacks of conventional intramuscular vaccinations. However, it is difficult to deliver DNA vaccines to target cells in the skin and polyplexes. This study outlines the development of an intradermal pH1N1 DNA vaccine delivery platform using microneedles (MNs) coated with a polyplex containing poly lactic-co-glycolic acid/polyethyleneimine (PLGA/PEI) nanoparticles (NPs). Stainless steel MNs with enhanced hydrophilicity have been manufactured by silanization, which improves coating efficiency...

The moisture from skin sweat and atmospheric water affects thermal protective performance provided by multilayer protective clothing. Four levels of moisture content were selected to evaluate the impact of moisture on thermal protection under dry (thermal radiation) and wet (thermal radiation and low-pressure steam) heat exposure. Also, the role of moisture and its relationship with exposure time were analyzed based on skin heat flux and Henriques integral value. It was found that the addition of moisture to a fabric system results in differences in second---- and third-degree skin burn times...

In this study, the effectiveness of washing with soap and water in removing nanoparticles from exposed skin was investigated. Dry, nanoscale hematite (α-Fe2O3) or maghemite (γ-Fe2O3) powder, with primary particle diameters between 20-30 nm, were applied to two samples each of fresh and frozen ex vivo human skin in two independent experiments. The permeation of nanoparticles through skin, and the removal of nanoparticles after washing with soap and water were investigated. Bare iron oxide nanoparticles remained primarily on the surface of the skin, without penetrating beyond the stratum corneum...

: Graft-versus-host disease (GVHD) is a major complication that occurs following allogeneic hematopoietic stem cell transplantation, which is a potential curative therapy used in a variety of malignant or benign hematological diseases. Graft-versus-host disease primarily occurs in many organs, but most notably in the skin, lungs, gastrointestinal tract, liver, eyes, mucosa, and musculoskeletal system. Ocular manifestations of GVHD may precede other systemic GVHD findings, and it may be a poor prognosis for mortality...

AIM: We hypothesized that feeling mucosal dryness in one body region and the skin may be associated with dryness in other regions and that there are common background factors for dryness. In an earlier web-based survey, we reported prevalence figures of dry eyes, nose, mouth, skin, and vagina. In the present study, additional analyses were made to investigate the factors associated with dryness in each region, and simultaneous dryness in multiple regions. METHODS: A web-based questionnaire was completed by 310 Japanese women...

Scar management is a recognised key component of rehabilitation following burn. Moisturising often combined with massage is commenced once healing tissue has gained sufficient strength to tolerate surface friction, with the aim being to hydrate the dry scar. The studies on various moisturisers and creams provide some guidance on moisturiser selection, but many are inconclusive. OBJECTIVE: This survey aimed to determine the current expert opinion regarding moisturiser recommendations, including the basis for these recommendations, across the burns community...

Itch is a common symptom in patients with skin and systemic diseases, but the effective treatment is limited. Here, we evaluated the anti-itch effects of the botulinum toxin type A (BoNT/A) using acute and chronic dry skin itch mouse models, which were induced by compound 48/80, chloroquine, and a mixture of acetone-diethylether-water treatment, respectively. Pretreatment of intradermal BoNT/A exerted long-term inhibitory effects on compound 48/80-induced and chloroquine-induced acute itch on days 1, 3, 7, and 14, but not on day 21, in mice...

BACKGROUND: Atopic dermatitis (AD) is a common pruritic inflammatory skin disease with increasing prevalence. It can manifest with many different clinical phenotypes; however, in its chronic stage, hyperpigmentation, excoriation, lichenification, and dryness are the main symptoms. Jaungo comprises two herbs, Lithospermi radix and Angelica gigantis radix, and three carrier oils, and is an approved herbal ointment for xerosis cutis in Korea. In past studies, we demonstrated that Jaungo had anti-inflammatory and antiallergic activity in in vitro and in vivo AD models; however, there are few relevant randomized controlled clinical trials on Jaungo in AD...

Recent studies have shown that the chemokine receptor CXCR3 and its ligand CXCL10 in the dorsal root ganglion mediate itch in experimental allergic contact dermatitis (ACD). CXCR3 in the spinal cord also contributes to the maintenance of neuropathic pain. However, whether spinal CXCR3 is involved in acute or chronic itch remains unclear. Here, we report that Cxcr3 (-/-) mice showed normal scratching in acute itch models but reduced scratching in chronic itch models of dry skin and ACD. In contrast, both formalin-induced acute pain and complete Freund's adjuvant-induced chronic inflammatory pain were reduced in Cxcr3 (-/-) mice...

Imatinib mesylate (imatinib) is a tyrosine kinase inhibitor initially approved by the US Food and Drug Administration in 2001 for chronic myeloid leukemia (CML). Since then, the number of indicated uses for imatinib has substantially increased. It is increasingly important that dermatologists recognize adverse cutaneous manifestations of imatinib and are aware of their management and outcomes to avoid unnecessarily discontinuing a potentially lifesaving medication. Adverse cutaneous manifestations in response to imat-inib are not infrequent and can include dry skin, alopecia, facial edema, and photosensitivity rash...

Water insoluble monohydrochloride monohydrate free ciprofloxacin (Cipro) antibiotic was incorporated in polyvinylpyrrolidone (PVP) polymer matrix by using acetic acid co-solvent in water. The resultant solutions were cast into fully transparent antimicrobial films. Proper concentrations of acetic acid eliminated in situ crystallization of the antibiotic and the resultant phase separation upon solvent evaporation. The solutions could also be electrospun into nanofiber mats (non-transparent). Presence of residual PVP-bound acetic acid in dry PVP films induced unprecedented levels of plasticity (stretching capacity) and softness to the films...
