Nitratos, nitritos y cáncer gástrico en Gran Bretaña
Nature
|February 21, 1985
Resumen
Los niveles de nitrato y nitrito saliva fueron más altos en un grupo de bajo riesgo de cáncer gástrico. Este hallazgo inesperado en los factores de riesgo de cáncer gástrico justifica una mayor investigación sobre estos iones salivales.
Área de la Ciencia:
- Gastroenterología y Gastroenterología.
- Oncología Oncología.
- La bioquímica es la bioquímica.
Sus antecedentes:
- El cáncer gástrico es una preocupación significativa para la salud mundial.
- Los nitratos y nitritos dietéticos están implicados como factores de riesgo potenciales.
- Los niveles salivales de estos iones pueden reflejar la exposición y la producción endógena.
Objetivo del estudio:
- Investigar los niveles de nitrato y nitrito salivales en poblaciones con diferentes riesgos de cáncer gástrico.
- Para explorar la relación entre estos iones y el riesgo de cáncer gástrico.
Principales métodos:
- Medición de las concentraciones de nitrato y nitrito en muestras de saliva.
- Comparación de los niveles de iones entre dos grupos de población distintos.
- Estratificación basada en factores de riesgo conocidos de cáncer gástrico.
Principales resultados:
- Se observaron concentraciones significativamente más altas de nitrato y nitrito en la población de bajo riesgo.
- Los hallazgos fueron contrarios a la hipótesis inicial que vinculaba los niveles más altos de iones con un mayor riesgo.
Conclusiones:
- Los niveles de nitrato y nitrito salivales pueden no estar directamente correlacionados con el riesgo de cáncer gástrico como se suponía anteriormente.
- Se necesita más investigación para dilucidar el complejo papel de estos iones en la carcinogénesis gástrica.

2° Amines to N-Nitrosamines: Reaction with NaNO2
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.
Nitric Oxide Signaling Pathway
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure to...
Antianginal Drugs: Nitrates and β-Blockers
In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...

Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Drug Delivery: Enteral Route
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Angina V: Nursing Management
Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...
