The purpose of this study was to determine the prevalence of oral lichen planus in a population of patients with diabetes mellitus compared with a control population and to determine if patient medications had any influence on the presence of such lesions. Two hundred seventy-three patients with diabetes and an identical number of age-, gender- and race-matched controls were examined for clinic...

Lichen studies, including biodiversity, phylogenetic relationships, and conservation concerns require definitive species identification, however many lichens can be challenging to identify at the species level. Molecular techniques have shown efficacy in discriminating among lichen taxa, however, obtaining genomic DNA from herbarium and fresh lichen thalli by conventional methods has been diffi...

In several families, multiple endocrine neoplasia type 2A (MEN 2A) has been found in association with cutaneous lichen amyloidosis. It has been debated, however, whether the skin amyloidosis found in MEN 2A families, localized exclusively in the interscapular area, represents the same anomaly as that found in autosomal dominant familial cutaneous lichen amyloidosis, which is more generalized. W...

For the first time for Western macroslope of Subpolar Urals, we identified 11 species oribatid mites. Here present a consolidated list Oribatida Urals which takes into account previously published data and includes 46 from 30 genera 24 families. We dominant in different plant communities mountain-tundra belt: grass-moss willow tundra on spring bank, dwarf birch-shrub-moss shrub-lichen tundra. c...

background: proliferating cell nuclear antigen (pcna) is a nuclear protein synthesized in the late g1 and s-phase of the cell cycle. detection of this protein represents a useful marker of the proliferation status of lesions. this study has been carried out to evaluate the cell proliferation rate in oral lichen planus (olp) and comparison between plaque and erosive lichen planus, which indicate...

Lichen planus is an inflammatory skin conditionwith characteristic histopathological findings thathas many clinical variants. Recently, there have been25 cases reported in the literature of lichen planuspigmentosus (LPPi) that preceded the developmentof frontal fibrosing alopecia (FFA), which is a variantof lichen planopilaris (LPP). We review the literatureregarding LPPi, LPP, and FFA and pres...

Oral lichen planus (OLP) is a common inflammatory disease with unknown etiology. Depression, stress and anxiety are psychological factors that their influence on the expression of lichen planus by affecting the immune system's function has been confirmed. There is a probable relationship between anger and OLP expression. Therefore, the present study aimed to evaluate the association of "anger" ...

Argumentation, having its roots back to ancient years, is used in many aspects of everyday life, such as law, politics, education and decision making. Argument Visualisation Tools serve the need of visualizing natural language’s argumentations, targeting in the elimination of the traditional community sites’ disadvantages such as the lack of expressiveness. This paper presents ArgVis, an argume...

The user can then browse posts by author or by topic or by period of time across all foru...

We review and present a synthesis of the existing research dealing with changing Arctic tundra ecosystems, in relation to caribou and reindeer winter ranges. Whereas pan-Arctic studies have documented the effects on tundra vegetation from simulated climate change, we draw upon recent long-term regional studies in Alaska that have documented the actual, on-the-ground effects. Our review reveals ...
