Background: Many of the most common cancers, such as prostate and breast cancer are due to the presence of harmful agents and compounds in processed foods, including nitrite. In this research the physicochemical, antioxidant, and color properties of sodium nitrite-free sausages containing different concentrations of cochineal pigment alone or in combination with cumin essential oil were studied...

Hydrogen sulfide poisoning from inhalation of roofing asphalt fumes is a rare but devastating injury. Two cases of toxic inhalation involving exposure to several gases, including hydrogen sulfide, evolved from cooling asphalt, are presented. Both victims were treated with supportive measures, including 100% normobaric oxygen, and one also received sodium nitrite. In one patient rapid, complete ...

Aging is associated with motor declines that lead to functional limitations and disability, necessitating the development of therapies to slow or reverse these events. We tested the hypothesis that sodium nitrite supplementation attenuates declines in motor function in older C57BL/6 mice. Motor function was assessed using a battery of tests (grip strength, open-field distance, rota-rod enduranc...

Nitrite oxidizes haemoglobin (Hb) to methaemoglobin (MetHb), which is unable to bind oxygen. Nitrite exposure can therefore be used as a tool to manipulate the oxygencarrying capacity of the blood without changing haematocrit. The objective of this study is to examine the relationship between the critical swimming velocity (Ucrit) and the functional haemoglobin concentration ([Hb]) of the blood...

CONTEXT Delayed cerebral vasospasm causes permanent neurological deficits or death in at least 15% of patients following otherwise successful treatment for ruptured intracranial aneurysm. Decreased bioavailability of nitric oxide has been associated with the development of cerebral vasospasm. OBJECTIVE To determine whether infusions of nitrite will prevent delayed cerebral vasospasm. DESIGN...

The objective of this study was to investigate survival kinetics of Campylobacter jejuni on various processed meat products (dry-cured ham, round ham with/without sodium nitrite, garlic seasoned ham with/without sodium nitrite, and sausage without sodium nitrite). Additionally, a semi-quantitative risk assessment of C. jejuni on various processed meat products was conducted using FDA-iRISK 1.0....

INTRODUCTION The efficacy of nebulized sodium nitrite (AIR001) has been demonstrated in animal models of pulmonary arterial hypertension (PAH), but it was not known if inhaled nitrite would be well tolerated in human subjects at exposure levels associated with efficacy in these models. METHODS Inhaled nebulized sodium nitrite was assessed in three independent studies in a total of 82 healthy ...

The method by which sodium nitrite may act to prevent germination or outgrowth, or both, of heat-injured spores in canned cured meats was investigated by using Clostridium perfringens spores. Four possible mechanisms were tested: (i) prevention of germination of the heat-injured spores, (ii) prior combination with a component in a complex medium to prevent germination of heat-injured spores, (i...

BACKGROUND Infusion of sodium nitrite could provide sustained therapeutic concentrations of nitric oxide (NO) for the treatment of a variety of vascular disorders. The study was developed to determine the safety and feasibility of prolonged sodium nitrite infusion. METHODOLOGY Healthy volunteers, aged 21 to 60 years old, were candidates for the study performed at the National Institutes of He...
