Malaxis acuminata D. Don., a small, terrestrial orchid, is endemic to tropical Himalayas at an altitude of 1200-2000m asl. The dried pseudobulbs are important ingredients of century old ayurvedic drug 'Ashtavarga' and a polyherbal immune-booster nutraceutical 'Chyavanprash', known to restore vigour, vitality and youthfulness. Considering tremendous medicinal importance of this threatened orchid species, a detailed study was undertaken for the first time to address its antioxidant potential, secondary metabolite contents and biological activities against skin-aging related enzymes (anti-collagenase, anti-elastase, anti-tyrosinase and xanthine oxidase) and anti-inflammatory activity (5-lipoxygenase and hyaluronidase) in different plant parts of wild and in vitro-derived plants of M...

Belatacept (CTLA4Ig) is an emerging treatment in kidney transplantation. Lack of nephrotoxicity and possibly an inhibitory effect on the development of donor specific antibodies (DSA) make it an interesting agent in hand transplantation. In order to reduce CNI immunosuppression and preserve kidney function, we have added belatacept to the therapeutic regimen of 4 hand transplanted patients at month 4, at 6, 9, and 13 years after hand/forearm transplantation. Patients received 5mg/kg belatacept every 2 weeks, the dosing interval was extended to 4 weeks after 5 applications...

Skin cancers caused by UV irradiation have been a major public health problem. One simple and effective way to avoid the above detrimental effects is the use of UV-protective sunscreens. However, there has been considerable concern with the issue of production of reactive oxygen species by the photo-degradation of commercial UV filters. Herein, we reported for the first time that the integration of ZnO nanoparticles and CeOx nanoparticles into hollow microspheres (ZnO/CeOx HMS) could provide broad UV spectrum protection and scavenge generated ROS under UV irradiation...

We present a case of a 61-year-old Caucasian woman who was hospitalized with fevers on day 176 after a matched unrelated stem cell transplant for acute myelogenous leukemia. She developed hemorrhagic bullae on the skin of her right thigh, and blood cultures and skin biopsy both confirmed Fusarium proliferatum. Despite antifungal therapy, her condition worsened and she died while on comfort-only measures. This article is protected by copyright. All rights reserved.

BACKGROUND: IgE-reactivity to antigens from gram-positive and negative bacteria is common in patients suffering from respiratory and skin manifestations of allergy, but the routes and mechanisms of sensitisation are not fully understood. The analysis of the genome, transcriptome and microbiome of house dust mites (HDM) has shown that S. aureus and E. coli species are abundant bacteria within the HDM microbiome. Therefore, our aim was to investigate if HDM are carriers of bacterial antigens leading to IgE sensitisation in patients suffering from atopic dermatitis...

Emergence of drug resistance has rekindled the interest in phage therapy as an alternative treatment option. Its potency, safety and proven efficacy is worth noting. However, phage therapy still suffers from issues of poor stability, narrow spectrum and poor pharmacokinetic profile. It therefore becomes essential to look into the use of Drug Delivery Systems (DDS) for efficient delivery of lytic phages in vivo For the first time, the present study has evaluated the use of nano-structured lipid based carriers i...

Nonalcoholic fatty liver disease is one of the most common complications of obesity. The Vitis vinifera L. grape skin extract (ACH09) is an important source of polyphenols, which are related to its antioxidant and antihyperglycemic activities. We hypothesized that ACH09 could also exert beneficial effects on metabolic disorders associated with obesity and evaluated ACH09's influence on high-fat (HF) diet-induced hepatic steatosis and insulin resistance in C57BL/6 mice. The animals were fed a standard diet (10% fat, control) or an HF diet (60% fat, HF) with or without ACH09 (200mg/[kg d]) for 12weeks...

Tissue-resident memory T (TRM) cells have been widely characterized in infectious disease settings; however, their role in mediating immunity to cancer remains unknown. We report that skin-resident memory T cell responses to melanoma are generated naturally as a result of autoimmune vitiligo. Melanoma antigen-specific TRM cells resided predominantly in melanocyte-depleted hair follicles and were maintained without recirculation or replenishment from the lymphoid compartment. These cells expressed CD103, CD69, and CLA (cutaneous lymphocyte antigen), but lacked PD-1 (programmed cell death protein-1) or LAG-3 (lymphocyte activation gene-3), and were capable of making IFN-γ (interferon-γ)...

The cross-linking of the IgA Fc receptor (FcαRI) by IgA induces release of the chemoattractant LTB4, thereby recruiting neutrophils in a positive feedback loop. IgA autoantibodies of patients with autoimmune blistering skin diseases therefore induce massive recruitment of neutrophils, resulting in severe tissue damage. To interfere with neutrophil mobilization and reduce disease morbidity, we developed a panel of specific peptides mimicking either IgA or FcαRI sequences. CLIPS technology was used to stabilize three-dimensional structures and to increase peptides' half-life...

Exposure to solar ultraviolet-B (UVB) radiation leads to the formation of cyclobutane pyrimidine dimers (CPDs). We investigated the protective effect of apigenin against UVB-induced CPDs formation in human dermal fibroblasts cells (HDFa). For this purpose, HDFa cells were treated with apigenin (15μM) prior to UVB irradiation (20mJ/cm(2)); DNA damage and subsequent molecular end points were observed. Exposure to UVB radiation increased significant CPDs formation in HDFa cells and the frequencies of CPDs were reduced by treatment with apigenin (15μM)...

BACKGROUND: Neutrophil (polymorphonuclear) granulocytes (PMN) were shown to contribute to the pathogenesis of psoriasis by releasing IL-17 and LL-37/ DNA complexes via neutrophil extracellular traps (NET), webs of chromatin strands decorated with antimicrobial peptides, in psoriatic skin. Fumaderm(®) , a fumaric acid ester (FAE) formulation consisting of different FAE salts has been successfully used to treat psoriasis for decades. Most recently, FAE treatment was reported to inhibit NET formation in murine epidermolysis bullosa acquisita...
