Filter by:Rugby is a team sport characterized by high-intermittent efforts, due to the importance of realizing intermittent and explosive efforts in rugby the use of nutritional strategies such as beetroot ingestion should be explored with the aim to enhance the capacity for repeating high-intensity actions in female players.
The purpose of this multi center, open label, randomized, study is to obtain information on the safety and efficacy of 150 ppm Nitric Oxide given in addition to the standard of care of patients with viral pneumonia
Obese people have a disturbed postprandial metabolism and thereby a decreased postprandial vascular function. Nitric oxide plays an important role in the postprandial vascular function. Multiple studies already focused on various nutritional compounds to improve the postprandial vascular function by increasing the nitric oxide bioactivity. However, the vast majority of the trials has been performed with relatively high doses of the individual components, which are problematic to convert into daily food measures, thereby preventing translation of these findings. Well-designed trails studying the effect of feasible amounts of nutritional supplements on the bioactivity of nitric oxide and vascular function are missing.
The aim of this study is to observe the mechanism of spreading vasodilatation on human healthy gingiva. Nitric-oxide donor solutions in lower and higher concentration are used to trigger the vasoactivity.
This prospective randomized study elucidates the effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit for cardioprotection against ischemia-reperfusion injury during coronary artery bypass graft surgery with cardiopulmonary bypass.
Asthma, abbreviation for bronchial asthma, is one of the common chronic airways disease that threatens human health. Typical symptoms of asthma are recurrent wheezing, shortness of breath, chest tightness and cough, usually occurring at night or early morning. However, there are still some patients with only persistent clinical manifestations of chest tightness. Concerned about this group of patients, we presented a subgroup of bronchial asthma, namely, chest tightness variant asthma (CTVA). This asthma subgroup usually lacks asthma-specific clinical features such as wheezing, shortness of breath, wheezing, and therefore often misdiagnosed for a long time. In order to further understand the clinical characteristics, pathogenesis, and prognosis of patients with CTVA, we conducted a national multicenter observation study to further understand CTVA. Finally, we plan to clarify whether CTVA is a relatively independent asthma phenotype. Meanwhile, reducing misdiagnosis and perform an appropriate treatment of CTVA.
This study evaluates the potential anti-inflammatory effects of inorganic dietary nitrate in a model of acute inflammation relevant to cardiovascular disease (CVD). Green leafy vegetables contain large amounts of inorganic nitrate, and research suggests that this nitrate has beneficial effects on the heart and blood vessels. The Ahluwalia Group have shown anti-inflammatory benefits of inorganic nitrate in pre-clinical models of CVD, early mechanistic studies in healthy volunteers, and in patients with hypertension, hypercholesterolaemia and those suffering acute heart attacks that translate to cardiovascular benefits. Understanding the mechanism of how this is achieved may open new therapeutic options in CVD. The Investigators therefore wish to explore whether inorganic nitrate might alter inflammatory responses using a blister-model of acute skin inflammation. This study is a randomised control trial with parallel limbs where half of patients receive nitrate-rich beetroot juice, and the other half a nitrate-deplete placebo beetroot juice.
Many types of cardiovascular disease begin when the layer of cells lining blood vessels (endothelial cells) start to function abnormally. This causes white blood cells (monocytes) to enter the blood vessel wall and eventually form lesions. Fats from foods we consume are carried in the blood for 3-8 hours after a fatty meal in small particles known as chylomicrons (CM) and chylomicron remnants (CMR). The overall aim of this project is to investigate the idea that n-3 polyunsaturated fatty acids (PUFA) protect against heart disease by modifying the effect of CMR on endothelial cells and monocytes. We hypothesize that n3-PUFA carried in CMR reduce detrimental events which promote blood vessel damage and activate protective mechanisms to improve the function of arteries.
The purpose of this study is to determine whether storage time affects how human body responds to autologous blood transfusion. An autologous blood transfusion is when a person donates blood and then receives that same blood back in the transfusion. We also want to find out if in this situation inhaled nitric oxide can help to prevent the potential reduction of vasodilation capacity. Vasodilation capacity is the ability of the blood vessel to widen when needed.
Nitric oxide (NO) was considered as a mediator of nasal inflammation and the measurement of nasal nitric oxide (nNO) may assist in the diagnosis of nasal inflammation. Few data exists comparing nNO with established, larger accepted reference standard for chronic rhinosinusitis (CRS) diagnosis. Moreover, the role of atopic status on nNO in nasal inflammatory diseases has not been reported. The aim of our study was to determine the value of nNO in patients with chronic nasal inflammation, and to assess the relationship between nNO and atopic status in these patients. A total of 131 randomized patients suffering form chronic nonallergic nasal inflammation and 20 healthy volunteers were finally recruited. nNO was measured by NIOX devices. Sinus computed tomography (CT) scan, nasal endoscope and nasal symptoms evaluation were used in the different diagnosis of chronic rhinitis (CR), CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP). Atopic status was confirmed by skin prick test and serum IgE levels. Blood eosinophils were evaluated simultaneously. Relationships among nNO, various atopic characteristics and chronic nasal inflammation were evaluated.
