Epstein-Barr Virus Linked with Multiple Sclerosis

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system of unknown etiology. Is a potentially disabling disease of the brain and spinal cord in which the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between the brain and the rest of the body. […]

Platelet-rich Plasma in Sports Medicine

Platelet-rich plasma (PRP) therapy includes a group of autologous blood products that are obtained from the patient’s own blood and is administered locally to treat various musculoskeletal disorders. Basic science and clinical research on PRP have expanded in recent years, particularly regarding the use of PRP to treat athletic injuries. These therapies have also gained […]

Alcohol Consumption Affected by Circadian Rhythm

Alcohol use disorder, which includes alcoholism, is a pattern of alcohol use that involves problems controlling your drinking, being preoccupied with alcohol, continuing to use alcohol even when it causes problems, having to drink more to get the same effect, or having withdrawal symptoms when you rapidly decrease or stop drinking.  Unhealthy alcohol use includes […]

Enzyme Linked to Immune Suppression in Cancer

Many tumors exhibit increased incorporation of sialic acids into cell-surface glycans, which impact the tumor microenvironment. Sialic acid immunoglobulin-like lectins (Siglec) are receptors that recognize sialic acids and modulate immune responses, including responses to tumors.  Tumors need to evade the immune system to grow and spread, causing cancer. One of the ways tumor cells hide […]

Olive Oil Consumption and Risk of Cardiovascular Mortality

Olive oil consumption has been shown to have health benefits, especially to lower cardiovascular disease risk, but its associations with total and cause-specific mortality are unclear. In a recently published study in the Journal of the American College of Cardiology, researchers evaluated whether olive oil intake is associated with total and cause-specific mortality in 2 […]

Loss of Taste After COVID-19

The clinical manifestations of COVID-19 can range from mild, cold-like symptoms typically associated with respiratory tract infections, such as cough and fever, to severe pneumonia with respiratory failure.  One of the common characteristics that sometimes differentiates COVID-19 from other respiratory diseases is the alteration of smell and/or taste. It mainly consists of a decrease or […]

Methods for Delivering Stem Cells for Regeneration of Heart Tissue after Myocardial Infarction

Myocardial infarction (MI) results in irreversible loss of cardiomyocytes (CMs) and can often lead to heart failure. Due to the minimal regeneration capacity of the myocardium, novel therapeutic techniques are needed. Myocardial infarction is a leading cause of morbidity and mortality worldwide and is the main cause of heart failure. It can be caused by […]

What is the Benefit of Vitamin D Supplementation on Myocardial Infarction and Mortality?

There is substantial evidence implicating vitamin D (Vit-D) levels in the pathogenesis of cardiovascular risk factors such as diabetes, hypertension, hyperlipidemia, chronic kidney disease, and obesity. Studies have suggested that vitamin D may participate in pathways associated with atherosclerosis by influencing cellular growth, oxidative stress, membrane transport, cell adhesion, and gene regulation.  According to the […]

Is There a Link Between IBD and Microplastics?

Human ingestion of microplastics (MPs) is inevitable due to the ubiquity of MPs in various foods and drinking water. Whether the ingestion of MPs poses a substantial risk to human health is far from understood.  Microplastics are fragments of any type of plastic less than 5 mm in length, according to the U.S. National Oceanic […]
