Flavonoids Biosynthesis

Flavonoids are the molecules derived from a core molecule flavan which are synthesized in plants and microbes by a complex process catalyzed by enzymes located in endoplasmic reticulum. These exist in human body in association with glycosides which can be absorbed in small intestine and are metabolized further in liver. This review consolidates the Biosynthesis of flavonoids in plant systems, its metabolism in human body, the role of different rings and groups on the antioxidant potential of flavonoids, the chemical mechanisms of its actions and finally clinical implications of these molecules against Alzheimer’s disease, Parkinson’s disease, cardiovascular diseases, diabetes, Osteoarthritis and Rheumatoid Arthritis and cancers.

Prevention Of Atherosclerosis

The participation of platelets in the development of atherothrombosis in acute forms of cardiovascular diseases is generally recognized and well studied, while their significance in the pathogenesis of vascular atherosclerosis, starting from the earliest stages, requires further study. This article analyzes the role of platelets in the pathogenesis of atherosclerosis. Modern views on the pathogenesis of atherosclerosis, platelet-endothelial interactions, molecular mechanisms of platelet activation, platelet immune function from the point of view of the initial stages of atherogenesis, studies of the effect of antiplatelet therapy in primary and secondary prevention of atherosclerosis are considered. The leading role of platelets in the inflammatory and immune reactions of the human body is indicated, which is realized due to a complex of immune receptors, adhesion molecules and mediators.

Selenium Status

Selenium is an important micronutrient that is essential for the functioning of the human body. Being a component of the active center of several antioxidant enzymes selenium prevents cell injury by free radicals. Decline in selenium-containing enzymes results in progression of oxidative stress and chronic inflammation, which are considered as possible causes for the development of many cardiovascular diseases. This review focuses on mechanisms for prevention of myocardial and vascular injury through the adequate selenium supply to the body. The importance of monitoring and correction of the selenium status in appropriate patients is underlined.

There is an increasing evidence linking dysbalance between various proinflammatory mediators and higher risk of cardiovascular events and pathologies. Likewise, some of the cardiovascular diseases lately appeared to have an autoimmune component. Interleukin-1 (IL-1), a master regulator of diverse inflammatory processes in higher eukaryotes and the key player in numerous autoimmune disorders including rheumatoid arthritis, diabetes mellitus or systemic sclerosis, has recently been proved to be involved in development of several cardiovascular diseases as well. This report aims to give a summary on current knowledge about the IL-1 signaling pathways and about the implication of IL-1 and the IL-1 receptor antagonist (IL-1Ra) in some of the diseases of the cardiovascular system.

Background. A large amount of experimental and clinical data on the content and the role of chemical elements in the human body is accumulated by nowadays. However, the state of mineral metabolism, mechanisms of action and the role of chemical elements in the etiology and pathogenesis of infl ammatory, autoimmune and other diseases are to be studied. Objective. To examine the state of mineral metabolism (calcium - Ca, magnesium - Mg, iron - Fe, cobalt - Co, copper - Cu, zinc - Zn) in various pathogenetic variants of infl ammatory processes in the blood serum of patients with acute coronary syndrome, community-acquired pneumonia and rheumatoid arthritis.

Normal Feature

The stage specific appearance of a retravirus, termed the Intracisternal A particle (IAP) is a normal feature of early preimplantation development. To date, all feral and laboratory strains of Mus musculus and even Asian species such as Mus cervicolor and Mus pahari express the particles during the 2-8 cell stages. IAP form by budding into the endoplasmic reticulum and appear singly or as groups of donut-shaped particles within the cisternae (fig. 1). IAP are also produced in large numbers in several neoplastic cells such as certain plasmacytomas and rhabdomyosarcomas. The role of IAP, either in normal development or in neoplastic behavior, is unknown.

SummaryBlood was injected into the brains of dogs to produce artificial haematomas, and paraffin injected to produce intracerebral paraffin masses. Cerebrospinal fluid (CSF) and peripheral blood samples were withdrawn at regular intervals and their fibrinolytic activities estimated by the fibrin plate method. Trans-form aminomethylcyclohexane-carboxylic acid (t-AMCHA) was administered to some individuals. Genera] relationships were found between changes in CSF fibrinolytic activity, area of tissue damage and survival time. t-AMCHA was clearly beneficial to those animals given a programme of administration. Tissue activator was extracted from the brain tissue after death or sacrifice for haematoma examination. The possible role of tissue activator in relation to haematoma development, and clinical implications of the results, are discussed.
