Significant negative correlations were noted between LC3 protein expression in psoriasis lesions and the mean epidermal thickness or inflammatory cell density. A significant negative correlation was found between AHR and LC3 expression in psoriatic skin. AHR, CYP1A1 and Nrf2 mRNA expression were upregulated while LC3, ATG5, and BECN1 mRNA were down-regulated, in psoriatic lesional skin compared with normal controls.
AHR and autophagy could play a role in psoriasis pathogenesis by modifying epidermal hyperproliferation and inflammation. AHR and autophagy regulation are potential therapeutic targets in chronic inflammatory skin diseases.

Nail psoriasis is a common clinically significant symptom of psoriasis. However, few studies have focused on the characteristics and course of toenail psoriasis.
To investigate the treatment response of toenail psoriasis during a 52-week period of ustekinumab use.
Patients were evaluated using the Nail Psoriasis Severity Index (NAPSI) at every injection visit. NAPSI score changes throughout the treatment were analyzed. Gambogic The treatment response in each toenail and each NAPSI characteristic was also analyzed.
A total of 22 patients with chronic plaque psoriasis with concomitant toenail psoriasis were examined. Several characteristics such as ridging or onychomycosis that mimic psoriasis or hinder the evaluation were identified. NAPSI significantly improved during the treatment (
<0.05). The big and second toes were significantly improved after 52 weeks of ustekinumab treatment (
<0.05). Pitting and oil-drop discoloration were the only two characteristics that showed significant changes post-treatment (
<0.05).
Ustekinumab proved to be efficacious in treating toenail psoriasis. Because of the factors that hinder the NAPSI scoring, only NAPSI scores of the first and second toes can be used.

Interleukin (IL)-19 and IL-20 are important members of the IL-10 cytokine family, which are known to play a role in inflammatory processes. Both anti-IL-19 and -IL-20 targeting drugs have been suggested in the treatment of inflammatory diseases such as psoriasis and rheumatoid arthritis. Recently, we presented I-kappa-B-zeta (IκBζ) as a key player in psoriasis by identifying IκBζ as a regulator of IL-17/tumor necrosis factor (TNF)α-inducible psoriasis-associated genes and proteins. Some of these genes were synergistically regulated by IL-17/TNFα.
The purpose of this study was to explore the role of IκBζ in the regulation of IL-17A/TNFα-mediated induction of IL-19 and IL-20 expression in human keratinocytes.
experiments with cultured primary humane keratinocytes were conducted and investigated by quantitative polymerase chain reaction (qPCR), Western blotting, ELISA and EMSA. For statistics, a one- or two- way repeated-measures analysis of variance (RM ANOVA) or the Friedman test (a nonparametric equivalent to the RM ANOVA) were conducted.
We demonstrated that IL-19 and IL-20 mRNA and protein expressions were synergistically induced by IL-17A and TNFα, whereas IL-17A and TNFα alone had only a minor effect on the IL-19 and IL-20 expression. Moreover, we demonstrated IκBζ to be a regulator of this synergistic induction of IL-19 and IL-20. Finally, the IL-17A/TNFα-induced synergistic induction of IL-19 and IL-20 expression was found to be mediated by a p38 MAPK-, NF-κB- and JNK1/2-dependent mechanism.
This study demonstrates that IκBζ plays a role in the IL-17A/TNFα-mediated synergistic induction of IL-19 and IL-20 in humane keratinocytes.

Recent studies have revealed that particulate matter induces inflammation, oxidative stress, and several skin diseases. link2 Experimental results have also shown that negative air ions are highly effective in removing particulate matter-induced inflammation.
The present study aimed to investigate whether negative air ions can inhibit inflammatory responses and reduce oxidative stress in HaCaT cells exposed to particulate matters.
HaCaT cells were treated with particulate matter in the presence or absence of negative air ions and the viability was evaluated by the MTT assay. Reactive oxygen species (ROS) generation was quantified by the dichlorodihydrofluorescein diacetate assay. The expression of genes and proteins was analyzed by real-time polymerase chain reaction and Western blot. Levels of inflammatory cytokines were quantified by enzyme-linked immunosorbent assay.
Negative air ions were observed to downregulate the mRNA and protein levels of particulate matter-induced pro-inflammatory cytokines in HaCaT cells. In addition, negative air ion treatment suppressed particulate matter-induced intracellular ROS generation, p38 mitogen-activated protein kinase activation, and activator protein 1 (c-Fos and c-Jun) activation.
Our findings indicate that negative air ions exert anti-inflammatory and antioxidant effects in HaCaT cells exposed to particulate matter. Therefore, negative air ions can be used for the prevention and treatment of particulate matter-related inflammatory skin diseases.

We recently discovered the presence of specialized nail mesenchyme below the nail matrix and designated it as onychomatricodermis.
We did further research to characterize the histologic, histochemical, immunohistochemical and ultrastructural features of the onychomatricodermis containing onychofibroblasts in the nail unit.
Ten polydactyly nail unit specimens and 8 nail matrix biopsies were included. H&E-stained slides were reviewed. We did Alcian blue staining and Masson Trichrome staining, as well as immunohistochemical staining for type I collagen, CD10, CD13 and CD34. In addition, polydactyly nail units were examined by transmission electron microscopy.
In H&E staining, the specialized mesenchyme called onychomatricodermis was observed to be slightly distant from the undersurface of the nail matrix and be less eosinophilic area. Onychomatricodermal onychofibroblasts showed light purple abundant cytoplasm. Masson Trichrome staining revealed fewer collagen fibers within the onychomatricodermiricodermis containing onychofibroblasts. In addition, we found morphological and immunohistochemical features of onychomatricodermal onychofibroblasts (onychofibroblasts of Dongyoun). These findings support the presence of onychomatricodermis containing onychofibroblasts in the nail unit.Atopic dermatitis (AD) is a chronic, inflammatory cutaneous disease driven by immune dysregulation and skin barrier dysfunction. Currently, we are experiencing a new era of understanding of the pathogenesis of AD and, as a consequence, a new era of innovation in therapeutics, including small molecules and biologic therapy. In contrast to biologics, small molecules are similar to conventional pharmacologic chemical agents used as drugs and are generally prepared by chemical synthesis. Unlike biologics, these drugs often are taken orally or formulated for topical use. The purpose of this review is to summarize the efficacy and safety of the current topical and systemic new therapies in AD by reviewing recently published papers on therapies currently in phase 2 or 3 clinical trials. In this review, it is important to note the characteristics of the study population, the primary endpoints, and whether or not there was concomitant topical therapy allowed. These study design elements may significantly alter the results of studies and should be taken into account. Targeted therapy help push AD treatment into a new era of personalized medicine.Background and Objectives Despite the easy acceptability and holistic nature of Kriya yoga, there are no studies evaluating the role of Kriya yoga intervention on depression. The objective of the current study was to assess the feasibility and effect of adjunctive Kriya yoga on depression. Methods Patients with major depressive disorder who opted for Kriya yoga were recruited into the intervention group (adjunctive Kriya yoga) and those on psychotropic medication alone were enrolled into the control group. The Hamilton Depression Rating Scale (HDRS) measurements were recorded at baseline, end of 2, 4, and 8 weeks. Results HDRS scores of the intervention group ( n = 29) were found to be significantly lesser than that of the control group ( n = 52) by the end of 2, 4, and 8 weeks. The remission rate was also significantly greater in the intervention group. Conclusion Kriya yoga intervention was found to be feasible, as well as improved the severity of depression.Objective Mental health care needs of urban, rural, and tribal regions of India are varied and challenging, which require region-specific approaches. A significant treatment gap calls out for a state-wise introspection of existing service delivery models to cater to the specific mental health needs. In Madhya Pradesh, key findings were noted from a camp conducted in one of the tribal districts. To establish patient-centered services, it is important to understand their mental health care needs. Materials and Methods A cross-sectional study within a mental health camp was conducted in the east-central tribal district of Madhya Pradesh by using a semi-structured interview. Statistical Analysis Treatment deficit, pathways to care, and treatment barriers were assessed for correlation with demographic and clinical variables and analyzed by using the Chi-square test and logistic regression method using SPSS version 20. Results Among 113 patients who sought help, treatment deficit was 85% with patient factors contributing 76% predominantly affecting the unmarried group of patients. Common mental illnesses (CMIs) outnumbered severe mental illnesses (SMIs) of which anxiety spectrum disorder contributed the most. SMIs still appear to remain undiagnosed till late in the course of illness. link3 Nicotine dependence was higher in males ( p less then 0.001), and an increase in the dependence pattern was observed with increasing age ( p = 0.001). Conclusion Rising awareness and recognition of CMIs as a common mental health concern while under-recognition of SMIs among tribal communities needs further research. Considering attribution of symptoms to unknown factors, treatment barriers revolving around patient factors, and higher nicotine dependence in males, a timely evaluation of a multitargeted intervention to establish the balance in access to mental health care among the tribal population of Madhya Pradesh is warranted.
