The measurement of cholesterol and triglycerides as indicators of metabolic disorders and most particularly of vascular disease risk has been of growing importance to physicians and epidemiologists over the past century. This was refocused on the lipoproteins, the specific packages in blood that carry these lipids, by John Gofman, MD, PhD, and Don Fredrickson, MD, more than 50 years ago. We continue to learn about the metabolism of these large molecular structures and their relationship to arteriosclerosis as new genetic and interventional studies are published...

Heparin is one of the oldest biological medicines with an established role in prevention and treatment of arterial and venous thromboembolism. Published therapeutic ranges for unfractionated heparin (UFH) mostly precede the large increase in the number of activated partial thromboplastin time (APTT) reagent/instrument combinations that now show wide variability. Areas covered: This paper explores the use of UFH, the development of heparin therapeutic ranges (HTRs), and the strengths and limitations of the methods used to monitor heparin's anticoagulant effect...

BACKGROUND: Chronic idiopathic axonal polyneuropathy (CIAP) is an insidiously progressive sensory or sensorimotor polyneuropathy that affects elderly people. Although severe disability or handicap does not occur, CIAP reduces quality of life. CIAP is diagnosed in 10% to 25% of people referred for evaluation of polyneuropathy. There is a need to gather and review emerging evidence on treatments, as the number of people affected is likely to increase in ageing populations. This is an update of a review first published in 2004 and previously updated in 2006, 2008, 2011 and 2013...

INTRODUCTION: Chronic apical periodontitis (CAP) manifests mostly as periapical radiolucency. Various inflammatory mediators play a significant role in the pathogenesis of apical periodontitis. In acute inflammatory conditions, C-reactive proteins (CRP) and fibrinogen show a rise in their concentrations. In chronic diseases with high inflammatory components, an increased prevalence of hypertension has been observed. Hence, we assessed the association of CAP and plasma levels of various inflammatory markers (CRP, interleukin 6 [IL-6], and fibrinogen) in severely hypertensive patients...

Animal models of concussion, traumatic brain injury (TBI), and chronic traumatic encephalopathy (CTE) are widely available and routinely deployed in laboratories around the world. Effective animal modeling requires careful consideration of four basic principles. First, animal model use must be guided by clarity of definitions regarding the human disease or condition being modeled. Concussion, TBI, and CTE represent distinct clinical entities that require clear differentiation: concussion is a neurological syndrome, TBI is a neurological event, and CTE is a neurological disease...

Accumulation of excess iron in heart can lead to cardiac dysfunction, which is the most common cause of death in thalassemia major patients. Biopsy is an invasive procedure and therefore not an ideal option to assess iron load. However, standard/usual non-invasive methods, such as ferritin measurement, have some limitations and the results show poor correlations with iron load. Magnetic Response Imaging (MRI-T2*), as a non-invasive and reliable method for iron load assessment in organs such as liver and heart, can be suggested as a favorable alternative...
