MCP-1 released by smooth muscle and endothelial cells promotes the recruitment of monocytes and macrophages to the subendothelial cell layer. Deposition of lipids within these monocytes and macrophages then leads to development of atherosclerotic lesions.

This is one of the 1st studies to demonstrate the effect of red blood cells on the disease and could also affect the way patients with other health conditions, like cancer, who are prone to developing cardiovascular issues, are diagnosed and treated. “White blood cells play a key role in fueling adipose tissue (fat) inflammation and insulin resistance in obesity and also promote the clogging of arteries, or atherosclerosis, setting the stage for heart attack and stroke...

Flexible sensors have been developed for use in electronics, robotics, health care, and space flight. Future possible applications could include the creation of ‘electronic skin’ and prosthetic limbs that allow wearers to ‘feel’ changes in their environments.

One problem with current flexible sensors they can be easily scratched and otherwise damaged, potentially destroying functionality. Researchers in the Dept of Chemical Engineering at the Technion, Israel, who were inspired by the healing properties in human skin, have developed materials that can be integrated into flexible devices to “heal” incidental scratches or cuts...

People who regularly drank moderate amounts of coffee daily –less than 5 cups per day — experienced a lower risk of deaths from cardiovascular disease, neurological diseases, Type 2 diabetes and suicide. The benefit held true for drinking caffeinated and decaffeinated coffee, suggesting it’s not just the caffeine providing health perks but possibly the naturally occurring chemical compounds in the coffee beans.

Drinking a second or third cup of coffee may do more than get you through a long day – it may also reduce your risk of death from heart disease and other illnesses.

Deposits of Beta-Amyloid in Fruit Flies Stopped by Using Porphyrin and Blue LED Lights

Medical application of photoactive chemicals offers a promising therapeutic strategy for neurodegenerative diseases. A Korean research team jointly led by Professor Chan Beum Park of Materials Science and Engineering Department at KAIST and Dr. Kwon Yu from Bionano Center at KRIBB conducted research to suppress an abnormal assembly of beta-amyloids by using photo-excited porphyrins.

Light-induced treatments using organic photosensitizers have advantages to managing the treatment in time and area. In the case of cancer treatments, doctors use photodynamic therapies where a patient is injected with an organic photosensitizer, and a light is shed on the patient’s lesion...
