background although, melasma is most prevalent among asian young women, and also darkly pigmented individuals are particularly prone to developing post inflammatory hyperpigmentation, to the best of our knowledge, there are rare or no studies about the association of melasma and post inflammatory hyperpigmentation. results we found out that 24.1% of patients without melasma had post-acne pigmen...

background acne vulgaris is a multifactorial disease of the pilosebaceous unit. malassezia furfur is one of the causative agents of the disease.it provides a proper environment for propionibacterium to grow. miconazole inhibits the propionibacterium growth by its fungicidal activity. objectives the aim of this study was to evaluate the treatment of acne vulgaris using the combination of topical...

4 General introduction 6 Paper I. 13 Are environmental factors influencing the prevalence of rust in pathosystem Falcaria vulgaris– Pucinia sii-falcariae? Paper II. 29 Low effect of pathogen on population characteristics in pathosystem Falcaria vulgaris–Pucinia sii-falcariae: matrix model results Paper III. 57 Effect of systemic diseases on clonal integration: modelling approach

Desulfovibrio vulgaris Hildenborough, a sulfate-reducing bacterium classified as an obligate anaerobe, swam to a preferred oxygen concentration of 0.02 to 0.04% (0.24 to 0.48 microM), a level which also supported growth. Oxygen concentrations of 0.08% and higher arrested growth. We propose that in zones of transition from an oxic to an anoxic environment, D. vulgaris protects anoxic microenviro...

The population biology of Loligo vulgaris and Loligo forbesi in Galician waters is described based on monthly samples from the fishery obtained during the period February 1991-June 1992. Maturity was assessed using a maturity scale and indices. The estimated number of oocytes in mature females varied from 782 to 21 885 in L. vulgaris and from 1317 to 14 956 in L. forbesi, and showed a slight po...

Brassinosteroids play a significant role in the amelioration of various abiotic and biotic stresses. In order to elaborate their roles in plants subjected to heavy metals stress, Chlorella vulgaris cultures treated with 10(-8) M brassinolide (BL) were exposed to 10(-6)-10(-4) M heavy metals (cadmium, lead and copper) application. Under heavy metals stress, the growth and chemical composition (c...

BACKGROUND Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action...

The response of Chlorella vulgaris when challenged by As(III), As(V) and dimethylarsinic acid (DMA) was assessed through experiments on adsorption, efflux and speciation of arsenic (reduction, oxidation, methylation and chelation with glutathione/phytochelatin [GSH/PC]). Our study indicates that at high concentrations of phosphate (1.62mM of HPO4(2-)), upon exposure to As(V), cells are able to ...

BACKGROUND AND AIMS The aim of this work was the identification and molecular characterization of novel sugar beet (Beta vulgaris) repetitive sequences to unravel the impact of repetitive DNA on size and evolution of Beta genomes via amplification and diversification. METHODS Genomic DNA and a pool of B. vulgaris repetitive sequences were separately used as probes for a screening of high-dens...

Biological invasion is regarded as one of the greatest environmental problems facilitated by globalization. Some hypotheses about the invasive mechanisms of alien invasive plants consider the plant-herbivore interaction and the role of plant defense in this interaction. For example, the "Shift Defense Hypothesis" (SDH) argues that introduced plants evolve higher levels of qualitative defense ch...
