  2. 1. Nitrates and Left Ventricular Dysfunction

    Author : Erik Tingberg; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid peroxidation; malondialdehyde; peptide; brain natriuretic peptide; left ventricular dysfunction; nitrates; acute myocardial infarction; heart failure; atrial natriuretic; diuretics; echocardiography; haemodynamic measurements; neurohumoral activation; diastolic dysfunction; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; Kardiovaskulära systemet; oxidative stress; isoprostanes;

    Abstract : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. READ MORE

  4. 2. Pharmacoepidemiologic studies on cardiovascular drugs - with special reference to the effectiveness and safety of blood pressure lowering drugs

    Abstract : Background: Ischaemic heart disease (IHD) and stroke are the main causes of morbidity and mortality in developed countries and hence constitute a large public health problem. Cardiovascular drugs are used in an effort to prevent (e. g. blood pressure lowering drugs (BPLD) and lipid lowering drugs) and palliate (e. READ MORE

  5. 3. Inorganic and organic nitrates as sources of nitric oxide

    Author : Mirco Govoni; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Inorganic nitrate (NO3-) and nitrite (NO2-) have generally been considered stable inactive end products of nitric oxide (NO) or unwanted residues in the food chain. While several recent studies surprisingly demonstrate that nitrite is reduced to bioactive NO in blood and tissues, the more stable anion nitrate is still considered to be inert. READ MORE

  6. 4. Nitric oxide in cardiovascular and renal disease : role of organic nitrates, inorganic nitrate and red blood cells

    Author : Zhengbing Zhuge; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : RATIONALE: Cardiovascular and renal disorders are major health problems, which are often co-existing. Mechanistically, these conditions can be attributed to endothelial dysfunction, a process coupled with reduced nitric oxide (NO) bioavailability. READ MORE

  7. 5. Kinetic Studies of NO Oxidation and Reduction over Silver-Alumina Catalyst

    Author : Muhammad Mufti Azis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TPD; Silver Alumina; HC-SCR; Kinetic modeling; Hydrogen effect; NOx reduction; NO oxidation.;

    Abstract : In line with growing concerns to manufacture more environmentally friendly vehicles, the use of internal combustion engines operating with oxygen excess or so called lean-burn engines will continue to be increasingly used. For lean-burn operation, reduction of NOx (NO+NO2) emissions is a major challenge and it is therefore urgently required to develop efficient and reliable NOx reduction aftertreatment systems for a wide variety of lean-burn or diesel engines.
