Formation of new lipoaminopeptides, acremostatins A, B, and C, was observed during co-cultivation of Acremonium sp. Tbp-5 and Mycogone rosea DSM 12973. Thus, co-cultivation of microorganisms producing related products could be suggested as a suitable way towards diversification of microbial structures.

The absolute stereochemistry of rhodiolosides A-D (1-4), four monoterpene glycosides from the roots of Rhodiola rosea, and their aglycones, rhodiolol A (5), (-)-rosiridol (6) and sachalinol A (7), were reinvestigated. It was found that the absolute configurations of C-4 in these compounds, previously assigned to be 4-R, should be revised to 4-S.

BACKGROUND Pityriasis lichenoides is a papulosquamous disorder of unknown etiology with remissions and exacerbations. Histopathology helps greatly in the diagnosis of this condition. AIM We studied clinical and histopathological features of pityriasis lichenoides in our patients. METHODS This is a 3-year retrospective and prospective, descriptive study of all patients clinically diagnosed a...

AIM: To report a case of a patient with pityriasis lichenoides et varioliformis acuta (PLEVA) who developed a conjunctival inflammatory nodule. CASE REPORT: a 13-year-old boy with a diffuse papulovesicular rash diagnosed as PLEVA presented to our clinic complaining of irritation in his right eye. Slitlamp examination revealed a conjunctival inflammatory nodule. His symptoms resolved under topic...

019 pityriasis rosea, Sjogren’s syndrome, subacute cutaneous lupus erythematosus, tinea corporis, erythema gyratum repens (EGR) and erythema annulare centrifigum. These can be differentiated by laboratory investigation and histopathological analysis. Specifically recurrent circinate erythematous psoriasis (Bloch), though clinically similar, is characterized by the presence of histopathological ...
