Lichen aureus (LA) is a variant of pigmented purpuric dermatosis that is characterized clinically by rust macules, papules or plaques, mainly on the legs. In some cases, LA can be difficult to be distinguished from nummular eczema (NE) with the naked eye. Dermoscopy can be applied to skin lesions, revealing additional features that can be highly valuable for correct diagnosis. This study was conducted to investigate characteristic dermoscopic findings of LA and to identify distinctive features that can differentiate it from NE...

Exacerbations of oral lichen planus (OLP) have been linked to the periods of psychological stress, anxiety and depression. The specific mechanism of the interaction is unclear. The aim of this study was to explore the candidate genes or molecules that play important roles in the interaction between OLP and depression. The BITOLA system was used to search all intermediate concepts relevant to the "Gene or Gene Product" for OLP and depression, and the gene expression data and tissue-specific gene data along with manual checking were then employed to filter the intermediate concepts...

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory disease of unknown cause that typically affects the genital area(1). It has been reported in post-traumatic areas as a result of Koebner´s phenomenon. LSA responds poorly to treatment making it a therapeutic challenge(2). Laser therapy has been described for LSA with variable results(3,4).

Lichen sclerosis (LS) is a chronic, relapsing disease with a variable presentation. In men, genitourinary LS may affect the penile foreskin, glans, meatus, and urethra. Treatment is multifaceted, ranging from pharmacotherapy to surgery. Urethral reconstruction due to stricture disease from LS is frequently plagued by a high recurrence rate. At the authors' institution, the high recurrence rate has shifted their practice toward potent steroids and minimally invasive surgical techniques. Management of recurrence includes dilation, meatotomy/meatoplasty, 1-stage and 2-stage repairs...

Frontal fibrosing alopecia (FFA) is a rare dermatologic disease that causes scarring and hair loss and is increasing in prevalence worldwide. FFA patients typically present with hair loss in the frontal scalp region and eyebrows which may be associated with sensations of itching or burning. FFA is a clinically distinct variant of lichen planopilaris (LPP) that affects predominantly postmenopausal women, although men and premenopausal women may also be affected. Early diagnosis and prompt treatment are necessary to prevent definitive scarring and permanent hair loss...

A 70-year-old woman presented with generalized reticulate pigmentation, scarring alopecia, and few discrete, violaceous plaques over the trunk and forearm. Dermoscopic evaluation of the reticulate plaque showed reticulate hyperpigmentation with multiple telangiectasias, and skin biopsy showed lichenoid interface dermatitis with marked pigment incontinence. Thus, a final diagnosis of poikiloderma due to lichen planus pigmentosus was considered.

Magnetotactic bacteria (MTB) are a group of phylogenetically and physiologically diverse Gram-negative bacteria that synthesize intracellular magnetic crystals named magnetosomes. MTB are affiliated with three classes of Proteobacteria phylum, Nitrospirae phylum, Omnitrophica phylum and probably with the candidate phylum Latescibacteria. The evolutionary origin and physiological diversity of MTB compared to other bacterial taxonomic groups remain to be illustrated. Here, we analyzed the genome of the marine magneto-ovoid strain MO-1 and found that it is closely related to Magnetococcus marinus MC-1...

OBJECTIVE: Oral lichen planus (OLP) is a chronic, inflammatory disorder that affects the oral mucous membrane. During an inflammatory response, several chemokines and cytokines are released by the cells of the immune system. Activation of MMPs, along with mast cell-derived chymase and tryptase, degrades the basement membrane structural proteins, resulting in basement membrane breaks. AIM: To investigate the association between the COX-2 expressions, presence of intact or degranulating mast cells within the connective tissue and the extent of basement membrane discontinuity in OLP cases...

Emissions of pollutants from highways can exert multiple stresses on adjacent ecosystems. In this study air concentrations of NO2 and throughfall deposition of inorganic N (NO3(-) and NH4(+)), SO4(2-), Cl(-), base cations and several metals were measured in all four seasons along a 1.5km hardwood forest gradient extending away from a major highway (Highway 401) in southern Ontario, Canada. Soil and lichen chemistry and herbaceous plant and epiphytic lichen species composition were measured within the hardwood forest to evaluate impacts of these pollutants...

Imaging mass spectrometry techniques have become a powerful strategy to assess the spatial distribution of metabolites in biological systems. Based on auto-ionisability of lichen metabolites using LDI-MS, we herein image the distribution of major secondary metabolites (specialized metabolites) from the lichen Ophioparma ventosa by LDI-MSI (Mass Spectrometry Imaging). Such technologies offer tremendous opportunities to discuss the role of natural products through spatial mapping, their distribution patterns being consistent with previous chemical ecology reports...
