Brown algae of the genus Cystoseira s. l. are key species in Mediterranean basin, including Black Sea and Azov. In addition to typical attached forms sensu lato (Ericaria crinita f. bosphorica (Sauvageau) S.S.Sadogurska, J.Neiva et A.Israel, Gongolaria barbata (Stackhouse) Kuntze), an unattached form was previously described for Sea. The taxonomic status this taxon remained uncertain. According...

During thermoregulation in the bearded dragon Pogona barbata, heart rate when heating is significantly faster than when cooling at any given body temperature (heart rate hysteresis), resulting in faster rates of heating than cooling. However, the mechanisms that control heart rate during heating and cooling are unknown. The aim of this study was to test the hypothesis that changes in cholinergi...

Malignant melanoma (MM) is the most dangerous type of skin cancer, killing more than 1,100 people each year in Canada. Prognosis for late stage and recurrent MM is extremely poor due to insensitivity to chemotherapy drugs, and thus many patients seek complementary and alternative medicines. In this study, we examined four commonly used anticancer herbs in traditional Chinese medicine, Hedyotis ...

What is it? • Usnic acid is a complex polycyclic chemical compound produced naturally by certain lichens species. • Lichens containing usnic acid have been used as traditional medicines and crude drugs in other countries. • Usnic acid as a pure substance has been formulated in creams, toothpaste, mouthwash, deodorants and sunscreen products, either as an active principle or a preservative.

The aim of this research is to develop a safe and effective anthelmintic from plants, due the resistance toxic effect synthetic anthelmintics on animals humans. There are several side effects for drugs including drug resistance, toxicity, residual in animal products. So there need exploration medicinal plants treatment different types worm infections.
 In medicinally traditionally importan...

The crude extract contains many compounds along with the various lichen metabolites and it is very difficult to say which compound(s) has the antioxidant potential unless and until it is purified. In the previous Chapter 3 & 4 the biological activities of Usnea ghattensis attributed to the crude extract containing usnic acid and norstictic acid have been presented. In order to know the antioxid...
