An Antioxidant Phytotherapy to Rescue Neuronal Oxidative Stress

An Antioxidant Phytotherapy to Rescue Neuronal Oxidative Stress

Oxidative stress is involved in the pathogenesis of ischemic neuronal injury. A Chinese herbal formula composed of Poria cocos (Chinese name: Fu Ling), Atractylodes macrocephala (Chinese name: Bai Zhu) and Angelica sinensis (Chinese names: Danggui, Dong quai, Donggui; Korean name: Danggwi) (FBD), has been proved to be beneficial in the treatment of cerebral ischemia/reperfusion (I/R).This study...

Deprenyl Can Mediate Neuronal Protection Rather than Neuronal Rescue

Background and Objective: Deprenyl is a drug for the treatment of Parkinson’s disease, where the dopaminergic neurons are the target of this drug. Several reports also documented that deprenyl has an effect on the sensory and motor neurons. There are some reports about the mode of action of deprenyl on m...

Oxidative Stress and Antioxidant Defense

Reactive oxygen species (ROS) are produced by living organisms as a result of normal cellular metabolism and environmental factors, such as air pollutants or cigarette smoke. ROS are highly reactive molecules and can damage cell structures such as carbohydrates, nucleic acids, lipids, and proteins and alter their functions. The shift in the balance between oxidants and antioxidants in favor of ...

An Overview of Oxidative Stress and Antioxidant Defensive System

Update on Oxidative Stress and Photosynthesis Understanding Oxidative Stress and Antioxidant Functions to Enhance Photosynthesis

Photosynthesis is a well-established source of reactive oxygen species (ROS) in plants. The photosynthetic electron transport chain (PET) operates in an aerobic environment; thus, regulatory systems are required to minimize ROS production. Moreover, an efficient antioxidant network is also essential in order to process ROS effectively and to maintain intracellular ROS pools at low levels. The i...
