In this study, we aimed to investigate how () affects the skin barrier and inflammation in AD and interacts with the AD therapeutic agents ruxolitinib and anti-IL4Rα.

Ex Vivo Treatment with Allogenic Mesenchymal Stem Cells of a Healthy Donor on Peripheral Blood Mononuclear Cells of Patients with Severe Alopecia Areata: Targeting Dysregulated T Cells and the Acquisition of Immunotolerance.

Alopecia areata (AA) is an autoimmune condition related to the collapse of the immune privilege of hair follicles. Certain AA populations present severe clinical manifestations, such as total scalp hair or body hair loss and a treatment refractory property. The aim of this study was to assess the effects of allogenic human mesenchymal stem cells (hMSCs) from healthy donors on the peripheral blood mononuclear cells (PBMCs) of severe AA patients, with a focus on the change in the cell fraction of Th1, Th17, and Treg cells and immunomodulatory functions.

Preventive Effects of a Human Hematopoietic Mesenchymal Stem Cell (hHMSC) Therapy in Ovalbumin-Induced Food Allergy.

No effective therapeutic strategies have been developed against food allergies. Immunomodulation during early infant period could prevent the development of food allergies. We investigated the preventive effects of human hematopoietic mesenchymal stem cells (hHMSCs) in mice with ovalbumin (OVA)-induced food allergy.

Mesenchymal Stem Cells Antagonize IFN-Induced Proinflammatory Changes and Growth Inhibition Effects via Wnt/β-Catenin and JAK/STAT Pathway in Human Outer Root Sheath Cells and Hair Follicles.

Mesenchymal stem cell therapy (MSCT) has been shown to be a new therapeutic option for treating alopecia areata (AA). Outer root sheath cells (ORSCs) play key roles in maintaining the hair follicle structure and supporting the bulge area. In human ORSCs (hORSCs), the mechanism for this process has not been extensively studied.

Inflammasome-mediated Inflammation by Malassezia in human keratinocytes: A comparative analysis with different strains.

Malassezia species are associated with several common dermatologic conditions including pityriasis versicolor, seborrhoeic dermatitis, folliculitis, and atopic dermatitis and dandruff. However, its causal role remains to be established. We intended to explore the role of inflammasome activation in human keratinocytes in response to three different Malassezia species.

Contribution of Autophagy-Notch1-Mediated NLRP3 Inflammasome Activation to Chronic Inflammation and Fibrosis in Keloid Fibroblasts.

Keloid is a representative chronic fibroproliferative condition that occurs after tissue injury. Emerging evidence showed that activation of NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) inflammasome is involved in the pro-inflammatory response in injured tissues. However, the role of NLRP3 inflammasome in keloid progression remains unclear.

Purpose: To investigate the prevalence and associated risk factors of low vision and blindness in the Korean population.

Methods: This cross-sectional, population-based study examined the ophthalmologic data of 22,135 Koreans aged ≥5 years from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V, 2010-2012). According to the World Health Organization criteria, blindness was defined as visual acuity (VA) less than 20/400 in the better-seeing eye, and low vision as VA of 20/60 or worse but 20/400 or better in the better-seeing eye.

Superamphiphilic Janus fabric.

Janus fabrics with superamphiphilicity were fabricated via electrospinning of polyacrylonitrile (PAN). PAN nanofibrous mats were formed on an aluminum foil substrate and then thermally treated to cause hydrolysis. An identical PAN solution was subsequently electrospun onto the hydrolyzed PAN layer, followed by peeling off of the bicomposite film from the collector substrate to produce a free-standing Janus fabric.

Robust superhydrophobic mats based on electrospun crystalline nanofibers combined with a silane precursor.

We demonstrate the fabrication of solvent-resistant, mechanically robust, superhydrophobic nanofibrous mats by electrospinning of poly(vinylidene fluoride) (PVDF) in the presence of inorganic silane materials. The solvent resistance and mechanical strength of nanofibrous mats were dramatically increased through the crystallization of as-spun PVDF fibers or incorporation of a tetraethyl orthosilicate (TEOS) sol into the nanofibrous matrix. The electrospun nanofibrous mats yielded a water contact angle of 156 degrees that did not vary with TEOS content.

Guideline development for the evaluation of visual impairment in Korea.

This guideline is developed to provide criteria for evaluating permanent impairment of the visual system as it affects an individual's ability to perform activities of daily living. This new assessment system is based on the 5th and 6th edition of American Medical Association and McBride impairment assessment system but revised on the consideration of Korean culture and simple application. This evaluation of impairment is based on an assessment of visual acuity and visual field.

Bilateral cataract surgery: a controlled clinical trial.

Purpose: To evaluate the efficacy and safety of simultaneous bilateral cataract surgery with respect to patient satisfaction, outcomes, and complication rates.

Methods: We conducted a prospective study of consecutive patients who had simultaneous bilateral cataract surgery on the same day or separate bilateral cataract surgery with an interval of 2 days between operations. The changes in refraction, visual acuity, degree of anisometropia, and complication rates were compared between the simultaneous bilateral cataract surgery and separate bilateral cataract surgery groups.

Validated LC-MS/MS method for quantification of gabapentin in human plasma: application to pharmacokinetic and bioequivalence studies in Korean volunteers.

A sensitive validated liquid chromatography-tandem mass spectrometric method (LC-MS/MS) for gabapentin (GB) in human plasma has been developed and applied to pharmacokinetic (PK) and bioequivalence (BE) studies in human. In a randomized crossover design with a 1-week period, each subject received a 300 mg GB capsule. The procedure involves a simple protein precipitation with acetonitrile and separated by LC with a Gemini C(18) column using acetonitrile-10 mm ammonium acetate (20:80, v/v, pH 3.

Phenotypic and immunoregulatory characteristics of monocytic iris cells.

The introduction of antigen into the anterior chamber of an eye induces the antigen-specific suppression of cell-mediated immunity and the antigen-induced production of immunoglobulin G2 antibodies. To define further the role of iris monocytic cells in the systemic suppression of cell-mediated immunity that follows the entry of foreign antigen into the anterior chamber, murine iris wholemounts or cell suspensions of iris cells were stained with fluorescent anti-F4/80 and/or anti-CD11c, anti-CD11b antibodies and examined by confocal microscopy or flow cytometry, respectively. Monocytic cells in iris cell suspensions were recovered from mice receiving an injection of trinitrophenylated bovine serum albumin (TNP-BSA) into an anterior chamber and Percoll-enriched iris cells separated into cells expressing F4/80 or CD11c were injected intravenously into TNP-BSA-immunized or naive recipients.
