OBJECTIVE Medicinal plants have attracted global attention due to their safety as well as their considerable antioxidant content that helps to prevent or ameliorate various disorders including memory impairments. This study was conducted to investigate the effect of beet root (Beta vulgaris) leaf extract on scopolamine-induced spatial memory impairments in male Wistar rats. MATERIALS AND METH...

Antisera were prepared against cytochromes c3 from Desulfovibrio africanus, D. vulgaris, and D. salexigens. Cross-reactions were observed between antisera to D. vulgaris and D. africanus cytochromes and heterologous cytochromes c3. A weak cross-reaction with antisera against both D. vulgaris and D. africanus cytochromes and the acid form of the D. salexigens cytochrome was seen; the basic form ...

Pemphigus vulgaris is an autoimmune disease associated with an autoantibody directed against a keratinocyte membrane antigen. The purpose of this study was to purify the human pemphigus vulgaris antigen, to produce an antibody to this antigen, and to use the antibody to induce pemphigus in newborn mice. Various techniques to extract the membrane-rich pellet from human epidermal homogenate were ...

The name Proteus penneri sp. nov. is proposed for a group of organisms previously called Proteus vulgaris indole negative or P. vulgaris biogroup 1. All of these strains were salicin negative, esculin negative, and chloramphenicol resistant (zone size, less than 14 mm). DNA relatedness studies indicated that when DNA from P. penneri strain 1808-73 was labeled and tested against unlabeled DNA fr...

Nutrients may affect the invasiveness of alien plants and the invasibility of native plant communities. We performed a greenhouse experiment to investigate the interactive effect of invasion by a clonal herb Hydrocotyle vulgaris and nutrient enrichment on biomass and evenness of native plant communities. We established three types of plant communities (H. vulgaris alone, native plant communitie...

This study aims to explore the correlation between microRNA-143 (miR-143) expression in peripheral blood mononuclear cells (PBMCs) and disease severity in patients with psoriasis vulgaris. From March 2014 to November 2015, 194 patients with psoriasis vulgaris (102 patients in progressive stage and 92 patients in stable stage) were selected as the case group and 175 healthy people as a control g...

Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded - 35 yrs earlier - by another wasp, Vespula germanica Although V. vulgaris wasps possess features that could be instrumental in overcoming obstacles through several invasion stages, the presence of preestablished populations of V. germanica could affect ...

Thymus hyemalis L. and Spanish T. vulgaris subsp. vulgaris shrubs are characterized by a great chemical intraspecific variability among plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. Because of this, clones of T. hyemalis and T. vulgaris were used to monitor seasonal variations in their aromatic composition o...

BACKGROUND There are two main clinical subsets of pemphigus: pemphigus vulgaris and pemphigus foliaceus. Clinical and epidemiological changes related to both types of pemphigus have been observed in the last years. OBJECTIVES To analyze a 21-year historical case series of pemphigus vulgaris and pemphigus foliaceus in the northeast region of the state of Sao Paulo, where pemphigus foliaceus is...

BACKGROUND Pemphigus vulgaris is a chronic inflammatory disease of skin, the etiology of which is not completely known. Despite the latter, anti-desmoglein antibodies play a proven role in the pathogenesis. Recent studies showed an etiologic effect for prolactin in the pemphigus vulgaris. This study aimed to quantify the correlation between serum prolactin levels and anti-desmoglein antibodies ...
