Lundberg, David S. The gaseous radical nitric oxide is involved in numerous physiologic and pathophysiological events important in anesthesiology and intensive care. Nitric oxide is endogenously generated from the amino acid l-arginine and molecular oxygen in reactions catalyzed by complex nitric oxide synthases.
Circulating NOx was affected by age, smoking habits, menopause status, thyroid hormones, and various pathologic conditions. Circulating NOx is associated with and could predict the risk of metabolic disorders in a general population. Nitric oxide NO , a simple ubiquitous signaling molecule, is suggested to be linked with several physiological processes including regulation of vascular homeostasis and blood pressure, inhibition of platelet activation, regulation of energy and lipid metabolism, mitochondrial biogenesis, and the modification of various physiological pathways 1 - 3. In this review, we aim to describe contributions of the Tehran lipid and glucose study TLGS to understanding different aspects of the nitrate NO 3 -nitrite NO 2 -nitric oxide NO pathway in health and disease. TLGS is an ongoing community-based prospective study being conducted to investigate and prevent non-communicable diseases NCDs , in a representative sample in the district 13 of Tehran, the capital city of Iran Inter- and intra-assay coefficients of variations of measurements were 5. In our adults, the reference values of serum NOx concentration were
Nitric oxide NO has multiple physiologic functions and its decrease or increase is associated with pathophysiology of diseases. The NO concentrations and rate of production from different pathways are determinants of its biological functions. NO at low levels produced by constitutive NOS maintains adequate blood flow and inhibits platelets in normal situation, while NO at high levels produced by inducible NOS plays role in pathophysiologic process. In NOS-independent pathway, NO is produced from nitrite by the nitrite reductase activity of deoxyhemoglobin. In thalassemia, iron overload and oxidative stress lead to endothelial dysfunction and decreased NO, which are associated with platelet hyperactivity and pulmonary hypertension.
The inorganic anions nitrate (NO3−) and nitrite (NO2−) were previously thought to be The nitrate–nitrite–nitric oxide pathway in physiology and therapeutics.
Nitric oxide nitrogen monoxide is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in many physiological and pathological processes. Standard pharmaceuticals such as nitroglycerine and amyl nitrite are precursors to nitric oxide.

Meta-analyses and several large cohort studies have demonstrated that antiseptic mouthwashes are associated with mortality in hospitalized patients. A clear pathogenic mechanism is lacking, leading to controversy and a reluctance to abandon or limit the use of antiseptic mouthwashes. Here, we generate the hypothesis that a disturbance in nitric oxide homeostasis by antiseptic mouthwashes may be responsible for the observed increase in mortality risk. Nitric oxide is essential in multiple physiological processes, and a reduction in nitric oxide bioavailability is associated with the occurrence or worsening of pathologies, such as atherosclerosis, diabetes, and sepsis. Oral facultative anaerobic bacteria are essential for the enterosalivary nitrate—nitrite—nitric oxide pathway due to their capacity to reduce nitrate to nitrite. Nitrate originates from dietary sources or from the active uptake by salivary glands of circulating nitrate, which is then excreted in the saliva.

Aims: Inorganic nitrate and nitrite from endogenous and dietary sources have emerged as alternative substrates for nitric oxide NO formation in addition to the classic L-arginine NO synthase NOS -dependent pathway. Here, we investigated a potential cross-talk between these two pathways in the regulation of vascular function. Results: Long-term dietary supplementation with sodium nitrate 0. Moreover, eNOS-dependent vascular responses were attenuated in vessels harvested from nitrate-treated mice or when nitrite was acutely added to control vessels.
Есть, но отец ее заблокировал. Он думает, что я балуюсь наркотиками. - А это не так? - спросил Беккер холодно, глядя на ее припухший локоть.
А-а, Росио - прелестное создание. - Мне нужно немедленно ее увидеть. - Но, сеньор, она занята с клиентом. - Это очень важно, - извиняющимся тоном сказал Беккер.
В этом освещении его лицо казалось мертвенно-бледным, безжизненным. - Сьюзан, - сказал. - Дай мне двадцать минут, чтобы уничтожить файлы лаборатории систем безопасности.
Несколько операторов очумело перебегали от одного терминала к другому, волоча за собой распечатки и отдавая какие-то распоряжения. В помещении царила атмосфера полного хаоса. Сьюзан завороженно смотрела на захватывающую дух технику. Она смутно помнила, что для создания этого центра из земли пришлось извлечь 250 метрических тонн породы. Командный центр главного банка данных располагался на глубине шестидесяти с лишним метров от земной поверхности, что обеспечивало его неуязвимость даже в случае падения вакуумной или водородной бомбы.
Фонтейну нужно было какое-то прикрытие - на всякий случай, - и он принял необходимые меры.
