Forty-five fungal isolates from moldy supermarket foods were tested for toxicity to brine shrimp, and twenty-two of these isolates were subsequently tested for toxicity to chicken embryos. Highly toxigenic fungi were Cladosporium sphaerospermum from a bakery product, Fusarium oxysporum from carrots, F. solani from cabbage, Aspergillus niger and Penicillium corylophilum from bread, P. cyclopium ...

In vitro studies were carried out to evaluate the cytotoxic potential of the ethanolic and aqueous extracts of Luffa acutangula against human neuronal glioblastoma cells (U343) and human lung cancer cells (A549). Screening of these extracts was done using the brine shrimp lethality bioassay, MTT assay and SRB assay. The results showed the significant decrease of the viability of the cells in a ...

Marine algal community signifies a huge source of compound endowed with ingenious structure and potential biological activities. Cytotoxicity of plant or fungal material is considered as the presence of antitumor compounds. In this study, ethanol extracts of seaweeds Dictyota dichotoma var. velutricata, D. hauckiana, D. indica, Iyengaria stellata, Jolyna laminarioides, Melanothamnus afaqhusaini...

Methanolic extracts of 11 Rumex L. species (Polygonaceae) were examined against brine shrimp and R. scutatus L. has shown significant brine shrimp lethality (LC5O=0.96 |a,g/ml). Methanolic extracts of the roots of R. scutatus were fractionated and the active fraction led to the isolation of 4 anthraquinone aglycones: emodin, chrysophanol, physcion and aloe emodin. Their toxic sequence was found...

phytochemical screening, antibacterial and cytotoxic activities of petroselinum crispum leaves grown in oman.petroselinum crispum belongs to the apiaceae family, is a well-known spice and vegetable. the essential oil obtained from the fruit has also strong action on the central nervous system. present study is designed to evaluate the phytochemical screening, antibacterial and cytotoxic activit...

background and objectives: salvia species are important because of their medicinal, traditional and economical uses. they are used traditionally for treatment of several diseases. the genus salvia is represented in the iranian flora by 61 species of which, 17 are endemic.  in the present study, the phytochemical and biological effects of two iranian salvia species have been evaluated. methods: ...

Objective: Phytochemical screening as well as several bioassays was performed on the extracts of aerial parts of Caragana jubata. Methods: Extraction of C. jubata was carried out by solvents of increasing polarity. The Phytochemical screening of extracts was carried out using standard procedures. Furthermore, extracts were also evaluated for (i) antibacterial assay, (ii) brine shrimp lethality ...

Copepods and brine shrimp, which represent different species of zooplankton with similar inertial time constant, can behave very differently when subjected to velocity gradients in unsteady or turbulent flows. Upon sensing hydrodynamic disturbances, copepods can respond with rapid acceleration and high speed. Brine shrimp, on the other hand are more passive and capable of only small relative sw...

The present investigation was undertaken in order to evaluate the cytotoxic effect of two D-galactose-binding lectins using the brine shrimp lethality bioassay technique. Both lectins were purified from the marine invertebrates, sea hare Aplysia kurodai eggs and polychaete Perineries nuntia by conventional affinity chromatography methods. The molecular mass of Aplysia kurodai egg lectin (AKL) w...
