Abstract:
Herbal medicine is an important field focused on the treatment and prevention of various health conditions that may occur due to oxidative stress. Our investigation aimed to determine the chemical composition, antioxidant, and the protective activity of polysaccharides isolated from Cinnamomum cassia (Cc-Ps). Cc-Ps underwent thorough characterization through various analytical methods, including UV, Fourier Transform Infrared (FTIR) spectroscopy, and HPLC. Our analysis showed that the Cc-Ps exhibited highest amount of uronic acid. In addition, Cc-Ps extract showed high ability to scavenge 2,2 diphenylpicrylhydrazyl radical (DPPH●), 2,2'-azinobis-(3 ethylbenzothiazoline-6 sulfonic acid radical (ABTS•+), and NO free radicals in reaction system. There was a noticeable decrease in the activity of key antioxidant enzymes such a superoxide dismutase and glutathione (GSH) peroxidase accompanied by an increase in malondialdehyde, a marker of oxidative stress. MET led to a clear impairment of the histopathological structure of both the liver and kidneys. Pretreatment with the polysaccharide extract normalized all biochemical and oxidative parameters. Virtual screening using docking simulations against "Drosophila melanogaster Acetylcholinesterase" was conducted to assess the bio-insecticidal properties of specific polysaccharide compounds derived from C. cassia. Polysaccharides were effectively protective in the liver and kidneys against the toxic effects of MET under our experimental conditions.

01:23Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Resting Phase:
In this phase, the cell's membrane is at its resting potential, typically around -70 millivolts (mV) for neurons. Inside the cell, there is a higher concentration of potassium ions (K+) and a lower concentration of sodium ions (Na+). Voltage-gated sodium channels are closed, and...
