Corticosteroids affect nitric oxide generation, total free radicals production, and nitric oxide synthase activity in monocytes of asthmatic patients.

Airways inflammation, a pathological hallmark of asthma, is associated with the recruitment of pro-inflammatory and inflammatory cells like eosinophils, polymorphonuclear leucocytes cells, mononuclear cells, macrophages, epithelial desquamation, and airways remodeling with sub-epithelial fibrosis. Activated inflammatory cells along with the resident cells can generate pro-inflammatory mediators including oxidants such as superoxide radicals, reactive oxygen species (ROS), and reactive nitrogen species. One of such inflammatory mediator that has received considerable attention is the nitric oxide (NO(•)) generated by pulmonary macrophageal/epithelial cells.

Mobile plaque in the internal carotid artery: A case report and review.

A mobile plaque in the carotid artery is an uncommon entity, usually detected incidentally on a carotid duplex scan or angiography. It is associated with an indeterminate risk of an embolic stroke and should be managed on an emergent basis. We report here a case of a mobile plaque in the internal carotid artery that was detected serendipitously in a carotid duplex scan.

Giant cell arteritis (temporal arteritis): A report of four cases from north east India.

Giant cell arteritis (GCA) is a common disease of the geriatric age group in the western world, with a prevalence of 0.2% in the fifty plus age group. It is an important cause of morbidity, with irreversible visual loss being the most ominous complication.
