  2. Gasotransmitters

    There are many gaseous chemicals with effects/functions in the human body, however only three of these act as bona fide 'gasotransmitters' (or gaseous transmitters): nitric oxide (NO, a free-radical mediator), carbon monoxide (CO) and hydrogen sulfide (H2S). These three regulate a variety of key biological functions and are also implicated in tumour biology. They can have endocrine, paracrine, and autocrine actions. They are produced enzymatically under tight regulation. They have varying biological half-lives, which affects their mode of transmitter action.

  3. Hypertension

    Elevated blood pressure (BP) is the product of increased cardiac output (CO) and peripheral vascular resistance (PVR). Increased CO may result from increased fluid volume from excess sodium intake or renal sodium retention, stimulation of the renin-angiotensin-aldosterone system (RAAS), or activation of the sympathetic nervous system (SNS). Functional constriction or structural hypertrophy of the vasculature increases PVR. Both result from excess stimulation of the RAAS, SNS overactivity, genetic alterations of cell membranes, or endothelial-derived factors.
