This paper describes a non-invasive mathematical method for estimating the locations and sizes of myocardial infarction using body surface electrocardiographic mappings. The inverse calculation is the theoretical basis of our method of estimation. First, the boundary integral equations were used to
In order to investigate the mechanism of deposition of the complement membrane attack complex (MAC) in cardiomyocytes in areas of human myocardial infarction, the 20 kDA homologous restriction factor of complement (HRF20; CD59) and complement components (Clq. C3d and MAC) were analysed
Myocardial infarction continues to be a major public health problem, not only in western countries but also increasingly in developing countries and makes significant contribution to the mortality statistics. Reduction in mortality rate and prevention of myocardial infarction are of utmost
Immune activation post-myocardial infarction is an orchestrated sequence of cellular responses to effect tissue repair and healing. However, excessive and dysregulated inflammation can result in left ventricular remodeling and pathological alterations in the structural and mechanical attributes of
We have developed a magnetic resonance (MR) spin echo method to obtain diffusion weighted imaging using motion-probing gradient (MPG) pulses in one or three orthogonal directions before and after a 180 degree pulse. Phantom models containing water and acetone, normal volunteers and patients with
1. Although the effect of glycerol on reducing intracranial pressure has been widely investigated, only a few studies have reported its dehydrating effect on brain oedema caused by infarction, ischaemia, microembolism and cold injury, but none on traumatic oedema. In this study the effects of
1. Anti-heart mitochondria autoantibodies were developed in serum from dogs following experimental myocardial infarction. 2. Heart mitochondria frozen and thawed repeatedly in a sucrose/Tris-chloride buffer retained both their functional integrity as measured by the respiratory control ratio and
Hypertension, one of the most common cardiovascular diseases that can cause coronary disease, stroke, myocardial infarction and sudden death, it is the major contributor to cardiac failure as well as renal insufficiency.As there are many cardio-active Reactions of normal and pathologic sera with heart tissue have been investigated by the immunofluorescent method, with particular reference to presumptive autoantibodies to heart and their differentiation from blood group isoantibodies and Wassermann antibody. In the heart, blood group substances A
With only 19 amino acids, duramycin is the smallest known polypeptide that has a defined 3-dimensional binding structure. Duramycin binds phosphatidylethanolamine (PtdE) at a 1:1 ratio with high affinity and exclusive specificity. As an abundant binding target, PtdE is a major phospholipid and
Extracts from the leaves of the Gingko tree (Ginkgo biloba L.) are therapeutically used for the treatment of peripheral and cerebral vascular disorders as well as multi-infarct or Alzheimer-type dementia. As constituents with potential contact allergenic and toxic properties in crude Ginkgo extracts
A 58-year-old man presented to the emergency department with acute left-sided weakness and left visual field defect. His examination was significant for confusion, acetone odour, tachycardia and tachypnoea. Further blood tests revealed an anion gap of 31 mEq/L, serum osmolal gap of 34 mOsm/kg, and
A variety of treatments have recently been introduced to improve the prognosis of hepatocellular carcinoma (HCC). These anticancer therapies include the oily carcinostatic agent styrene maleic acid neocarzinostatin (SMANCS). SMANCS is a chemical conjugate of a synthetic copolymer of styrene maleic
The acute-phase protein C-reactive protein (CRP) recruits C1q to the surface of damaged cells and thereby initiates complement activation. However, CRP also recruits complement inhibitors, such as C4b-binding protein (C4bp) and factor H, which both block complement progression at the level of C3 and
