Abstract

In various diseases, there is an increased production of the free radicals needed to carry out certain physiological processes but their excessive amounts can cause oxidative stress and cell damage. Enzymes play a major role in the transformations associated with free radicals. One of them is nitric oxide synthase (NOS), which catalyzes the formation of nitric oxide (NO). This enzyme exists in three forms (NOS1, NOS2, NOS3), each encoded by a different gene. The following work presents the most important information on the NOS isoforms and their role in the human body, including NO synthesis in various tissues and cells, intercellular signaling and activities supporting the immune system and regulating blood vessel functions. The role of NOS in pathological conditions such as obesity, diabetes and heart disease is considered. Attention is also paid to the influence of the polymorphisms of these genes, encoding particular isoforms, on the development of these pathologies and the role of NOS inhibitors in the treatment of patients.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Nitric oxide, a metabolite of L-arginine, has a role in sexual functions.

    “Nitric oxide is one of the metabolites of L-arginine, which has many activities in the body, including its role in sexual functions [29].”

    From Effect of l-arginine compared to placebo on sexual function in women with major depressive disorder: a randomized controlled trial (2024) · cites this paper as [29]

    Section 2, “Characteristics of NO and Its Derivatives” (page unavailable), says NO is formed from arginine by nitric oxide synthase. Section 5, “Selected NOS Inhibitors and Their Role in Therapy” (page unavailable), describes NO’s role in genitourinary neurotransmission, but the passages do not specifically address sexual functions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
