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...

One pollutant which seriously threatens water resources is dye. Therefore, finding a suitable method to separate the dye in water resources is very important. An adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. In this study, Erythrosine dye removal from an aquatic environment using natural absorbents, namely Sorghum and Ziziphus nummular...

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...

background: leishmaniasis has been identified as a major public health problem in tropical and sub-tropical countries. the present study was aimed to investigate antileishmanial effects of various extracts of berberis vulgaris also its active com-poenent, berberine against leishmania tropica and l. infantum species on in vitro ex-periments. methods : in this study in vitro antileishmanial activ...

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...

Chinese jujube (Ziziphus jujuba Mill.) has long been widely used for human consumption and medicinal purposes in China. It has been reported to possess several vital biological activities. However, the systematic study on the chemical constituents absorbed into plasma and their metabolites is still insufficient.A high-performance liquid chromatography-photodiode array detector-electrospray ioni...

An experiment was conducted to evaluate the effect of Ziziphus mucronata and Parkia biglobosa on haematological and biochemical indices of sheep. The experiment was carried out in a complete randomized block design. A total of 32 animals were used for the study with 16 animals per experiment. The animals were allotted to four dietary treatments with four animals per treatment. The results of th...

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...
