Physiological Processes

Nitric oxide (NO) is a gaseous diatomic molecule with a wide variety of physiological and pathological implications in plants. Presence of unpaired electron in its molecular orbital makes it highly reactive; it can react directly with metal complexes, radicals, DNA, proteins, lipids and other biomolecules. Nitric oxide (NO) and reactive oxygen species (ROS) are known to play essential role in a number of important plant physiological processes. This manuscript reviews the role of NO on these processes during various biotic and abiotic stresses.

Immunological Factors

Endometriosis is a silent, unseen and painful female illness which is characterized by the presence of glands and stroma outside the uterine cavity. Approximately one in ten women in a reproductive age around the world suffer from endometriosis of whom nearly half is treated due to infertility. The pathogenesis and mechanisms that determines the occurence of the disease are still unknown. Immunological factors have been observed in the initiation and development of endometriosis. An imbalance between reactive oxygen species (molecules having an unpaired electron) and antioxidants leads to the upregulation of metalloproteinases, prostaglandins, cytokines and chemokines.
