In silico study reveals binding potential of rotenone at multiple sites of pulmonary surfactant proteins: A matter of concern.

Rotenone is a broad-spectrum pesticide employed in various agricultural practices all over the world. Human beings are exposed to this chemical through oral, nasal, and dermal routes. Inhalation of rotenone exposes bio-molecular components of lungs to this chemical.

Antioxidant activity and structural features of Cinnamomum zeylanicum.

The antioxidants in food materials have recently attracted researchers' attention because many reports have shown that the oxidative stress is closely related to the aging process of the cells and acts as a trigger to various diseases including cancer. Since reactive oxygen species (ROS) is involved in initiating and promoting several diseases such as cancer and cardiovascular events, this study was designed to evaluate the antioxidant capacity of pectic polysaccharides extracted from the bark of Cinnamomum zeylanicum, locally known as Daruchini. An arabinogalactan (A), one partly methyl esterified galacturonic acid (B) and a neutral glucan (C) were isolated.
