Amornpol Anuwatworn, * Prince Sethi, Kelly Steffen, Orvar Jonsson, and Marian Petrasko Abstract Alport syndrome (AS) is a genetic disorder due to inheritance of genetic mutations which lead to production of abnormal type IV collagen. AS has been associated with renal, auditory, and ocular diseases due to the presence of abnormal alpha chains of type IV collagen in the glomerulus, cochlea, […]

Missouris 2 , 3 Abstract Varicella-zoster virus (VZV) infection can rarely lead to serious cardiac complications and life-threatening arrhythmias. We present a case of a 46-year-old male patient who developed VZV myocarditis and presented with recurrent syncopal episodes followed by a cardiac arrest. He had a further collapse eight years later, and […]
Read MoreAbstract Background Arthritis is one of the most common comorbidities in heart failure (HF) patients, and is associated with decreased activity levels. Few studies have examined sedentary behavior (SB) in HF patients with arthritis, and little is known about the factors that may influence SB in this population. Methods This is a retrospective, secondary analysis […]
Read MoreIs Lipoprotein (a) a Risk Factor for Coronary Artery Ectasia? Abstract Background The pathophysiology of coronary artery ectasia (CAE) is under investigated and not well understood. Atherosclerosis is considered as the main etiologic factor for CAE in adults where more than 50% of CAE patients have atherosclerosis. Recently, lipoprotein (a) (Lp(a)) has emerged as a […]

Read MoreCorticosteroids are key regulators of whole-body homeostasis that provide an organism with the capacity to resist environmental changes and invasion of foreign substances. The effects of corticosteroids are widespread, including profound alterations in carbohydrate, protein, and lipid metabolism, and the modulation of electrolyte and water balance. Corticosteroids affect all of the major systems of the […]
Read MoreAbstract Background Several epidemiological studies have investigated the association between dietary fat intake and cardiovascular disease. However, dietary recommendations based on systematic review and meta-analysis might be more credible. Methods and results Pubmed, Embase and Cochrane library were searched up to July 1st 2018 for cohort studies reporting associations of dietary fat intake and risk […]

The success […]
Read MoreA 7-month-old male infant was brought to the hospital after being found by his foster parents to be inconsolable and crying. He was up-to-date on his immunizations and met all his developmental milestones. Significant birth history included intrauterine exposure to methamphetamine, with a positive methamphetamine drug screen at birth, and subsequent removal from his mother […]
Read MoreWilson Greatbatch — who was born 100 years ago today — was tinkering with an oscilloscope in 1956 when he installed the wrong resistor and accidentally invented the implantable artificial pacemaker. Greatbatch noticed the device could be altered to drive a heartbeat and realized this was exactly what was needed to replace the bulky, painful […]
Read MoreDecellularization (also spelt decellularisation in British English) is the process used in biomedical engineering to isolate the extracellular matrix (ECM) of a tissue from its inhabiting cells, leaving an ECM scaffold of the original tissue, which can be used in artificial organ and tissue regeneration. Organ and tissue transplantation treat a variety of medical problems, ranging from end organ failure to cosmetic surgery. One of the greatest limitations […]
