Total, soluble, insoluble oxalate and mineral content of 20 edible mushrooms were measured using spectroscopic and enzymatic methods. Total oxalate content ranged from 45 (Hericium erinaceus) to 104 (Morchella conica), mg/100 g dry matter (DM), while the soluble oxalate levels ranged from 34 (Lactaius delicious) to 65 (Phellinus florida) mg/100g DM but not detected in Hericium erinaceus, Sparas...

This study was conducted to investigate the cytotoxicity and apoptosis effect of A. crispa extract and its solvent partition (ethyl acetate and aqueous extract) against Mus musculus mammary carcinoma cell line (4T1). The normal mouse fibroblast cell line (NIH3T3) was used as comparison for selective cytotoxicity properties. The cytotoxicity evaluation was assessed using MTT assay. AO/PI dual fl...

nepeta depauperata belongs to the lamiaceae family and is one the persian endemic plants which has not been investigated biologically. in the present paper we had focused on the assessment of the antibacterial and antifungal activities of the total methanolic extract and different sub-fraction of the flowering aerial parts of it. the antibacterial and antifungal activities were investigated by ...

Wild animal hunters and photographers have long taken advantage of the attraction that catnip holds over members of the cat family, while domestic cat owners purchase dried catnip leaves for use as a rejuvenator and exerciser that will bring old cats to new life. Indeed, when cats have the leaves placed near them, they immediately approach, sniff, and shortly thereafter rub their faces into the...

Fuel pollution is a significant problem in Antarctica, especially in areas where human activities occur, such as at scientific research stations. Despite this, there is little information on the effects of petroleum hydrocarbons on Antarctic terrestrial biota. The authors demonstrate that the Antarctic mosses Bryum pseudotriquetrum, Schistidium antarctici, and Ceratodon purpureus, and the Antar...

Ammonia-oxidizing bacteria (AOB) and archaea (AOA) are important for nitrogen cycling in marine ecosystems. Little is known about the diversity and abundance of these organisms on the surface of marine macroalgae, despite the algae's potential importance to create surfaces and local oxygen-rich environments supporting ammonia oxidation at depths with low dissolved oxygen levels. We determined t...
