Pyrethroids play an important role in modern agriculture but their use is not without risks to non-target organisms and habitats. They have high toxicity to a broad spectrum of aquatic organisms. The aim of the study was to investigate the effect of low concentration (0.02 μg l(-1)) of two widely used pyrethroids--cypermethrin and deltamethrin on phyto- and zooplankton. The acute bioassays were...

Background: Sudamala herb (Artemisia vulgaris L.) is often used in society as an anti tumor for organs of digestive system including oral cavity. Nevertheless, there are still no further scientific researches on active materials which can be used as anti carcinogen in oral cavity. Most of anti carcinogens are actually obtained from the genus Artemisia. Moreover, in Indonesia, the species of the...

The essential oil composition of Thymus vulgaris L. and Rosmarinus officinalis L. endemic to France were determined by GC and GC-MS. Oils were assessed for their cytotoxic, antioxidant and antimicrobial activity. 31 and 37 different compounds were identified representing 99.64% and 99.38% of the thyme and rosemary oils respectively, where oxygenated monoterpenes constituted the main chemical cl...

One of the key features of major histocompatibility complex (MHC) genes is the frequent occurrence of trans-species polymorphism, that is 'the passage of allelic lineages from ancestral to descendant species' (Klein et al. 2007). Selectively maintained ancestral polymorphism may, however, be hard to distinguish from introgression of MHC alleles between hybridizing species (Fig. 1). In this issu...

BACKGROUND & OBJECTIVES Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance underlines the importance of discovering new therapeutic products. The present study aims to investigate the in vitro antileishmanial activity and cytotoxicity of the ethanolic extract of Berberis vulgaris fruits and chloroform extract of Nigella sativa seeds against Leishmania...

The objective of the present work was to evaluate the effect of exogenously applied cadmium on the physiological response of green algae Chlorella vulgaris. The study investigated the long-term effect (18 days) of cadmium on the levels of algae biomass, assimilation pigment composition, soluble protein, oxidative status (production of hydrogen peroxide and superoxide anion), antioxidant enzymes...

The evaluation of antioxidant capacity, total phenolics, vitamin C content and identification of several phenolic acids and flavonoids was performed in the following fresh and dried herbs widely used in folk medicine throughout Slovenia and elsewhere: elder berries (Sambucus nigra L.), barberries (Berberis vulgaris L.), rowan tree berries (Sorbus aucuparia L.), coltsfoot flowers (Tussilago farf...
