Peripheral Arterial Insufficiency

Plaque formation in the arteries carrying blood to the head and neck is a serious medical problem, potentially leading to strokes and heart attacks. In Physics of Fluids , by AIP Publishing, engineers from China use fluid dynamics simulations to study the effect of exercise at various ages on plaque formation. It has been known for years that exercise and age affect the formation of plaques through a process known as atherosclerosis. What has not been fully understood, however, is how the geometrical features of the arteries affect plaque formation, although a dilated region in the inner carotid branch, the sinus, appears to be a vulnerable site. "It is commonly accepted that the disturbed flow induces atherosclerosis," said author Xiaolei Yang. To study this, the authors considered two arterial geometries, one with a bulging outer artery and the other without, and modeled the effect of exercise and age on blood flow through the two model arteries. Two main arteries c

A receptor activated by substances formed from omega-3 fatty acids plays a vital role in preventing inflammation in blood vessels and reducing atherosclerosis, a new study from Karolinska Institutet in Sweden published in The Journal of Clinical Investigation reports.The discovery can pave the way for new strategies for treating and preventing cardiovascular disease using omega-3 fatty acids. Cardiovascular disease is the most common cause of death globally and a serious public health problem. Atherosclerosis is associated with chronic inflammation in the blood vessels. Inflammation a is normally controlled by stop signals called resolvins, which switch off the inflammation and stimulate tissue healing and repair through a process called resolution of inflammation. Resolvins are formed from omega-3 fatty acids and bind to and activate a receptor called GPR32. "We've found that this receptor is dysregulated in atherosclerosis, indicating a disruption in the body's nat

A middle cerebral artery stroke is an interruption of blood flow in the middle cerebral artery (MCA). Strokes happen when a blood vessel is blocked or ruptured. A stroke is always a medical emergency. It can cause permanent brain damage because brain cells die if they don't get a constant supply of oxygenated blood. This article will look at the MCA and what it does, symptoms and causes of MCA strokes, and how they're diagnosed and treated. MedicalRF.com / Getty Images What is the Middle Cerebral Artery? The arteries in your brain come in symmetrical pairs. Each one has a left and right artery. The MCAs are vital blood vessels that branch off from the internal carotid arteries. The internal carotid arteries are branches of the common carotid arteries. Those are large blood vessels in your neck. The MCA is the largest branch of the internal carotid arteries. It can be involved in large strokes. What Does the MCA Do?

Newswise — Researchers at the University of Chicago Medicine have found new potential drug targets to treat atherosclerosis and coronary artery disease by developing and implementing a new single-cell sequencing workflow that could improve upon those currently in use. The approach will make it easier for other scientists to analyze single-cell genetic data to better understand coronary artery disease as well as other disease states and biological systems. The team used their cardioinformatics pipeline to reveal new types of vascular cells derived from the smooth muscle cells found in the walls of arteries, along with insight on the communication pathways among those cells. "This is one of the first studies to show how big data, single-cell sequencing and genomics can be leveraged to find new drug targets in heart disease, which is the number one global killer," said Bohdan Khomtchouk, PhD, co-senior author on the study and an instructor in the Section of Computationa

Overview Colon and small intestine Open pop-up dialog box Close Colon and small intestine Colon and small intestine The small intestine and colon are components of your digestive tract, which processes the foods you eat. The intestines extract nutrients from the foods. What isn't absorbed by the intestines continues along the digestive tract and is expelled as stool during a bowel movement. Diarrhea can be present due to abnormalities in the small intestine or the large intestine. Intestinal ischemia (is-KEE-me-uh) describes a variety of conditions that occur when blood flow to your intestines decreases due to a blocked blood vessel, usually an artery. Intestinal ischemia can affect your small intestine, your large intestine (colon) or both. Intestinal ischemia is a serious condition that can cause pain and make it d

Minnesota has the lowest age-adjusted heart disease mortality in the U.S.; yet, African American adults 35 to 63 have nearly double the rate of death from cardiovascular disease, compared to their white counterparts. Study findings show that basic health beliefs and demographics, such as age, sex, marital status and level of education attained, were associated with the risk factors for cardiovascular disease. Of the study group, the prevalence of common risk factors were hypertension, 68%; hyperlipidemia, 47%; diabetes, 34%; and current cigarette smoking, 25%. Also, 18% of participants had cardiovascular disease, and the pervasiveness increased by 30% or greater with three or more risk factors. The increased risk factors and prevalence of cardiovascular disease stands out because our findings are significantly higher than found in previously documented studies."

Lots of things can leave your skin parched, cracked, or even bleeding, including frequent handwashing, hand sanitizer use, cold or windy weather, or certain skin conditions. Most things in your life aren't within your control, but this one is — so get a hand cream that's actually effective. "As the temperatures get colder and there's less humidity in the air, combined with brisk winds as well as indoor heating, which is usually quite dry, all of those things make us lose more moisture from our skin into the air," said Dr. Hadley King, a board-certified dermatologist and clinical instruc

The weather outside might be frightening, but that doesn't mean your skin has to show it. With these winter moisturizers, your skin can stay hydrated and healthy in the coldest months.

Eyebrow dandruff and scalp dandruff have similar symptoms and causes. Eyebrow dandruff causes itchy, whitish skin flakes that shed, and—just like with regular dandruff—there are several types of eyebrow dandruff, depending on the underlying cause. This article focuses on the symptoms, causes, diagnosis, treatment, prevention, and prognosis of eyebrow dandruff. Sergey Dogadin / Getty Images Symptoms The symptoms of eyebrow dandruff may include: Light, white to yellowish flakes of skin that shed Mild erythema (redness) and irritated patches of skin on the eyebrows Mild itching (or in some cases, there is no itching) A rash in some types of eyebrow dandruff (such as when contact dermatitis is the underlying cause) A scaly appearance of the eyebrows An increased amount of sebum (oil) in the eyebrows Note, when eyebrow dandruff is caused by environmental factors—such as cold weather or harsh skin products—the symptoms do not include inflamma

"Intrinsic eczema" is a term referring to atopic dermatitis (AD) that isn't related to genetics, allergies, or other common causes of this skin condition. It's estimated that between 10 and 40 percent of people with AD have this type of eczema, according to a 2015 research review, and it mostly affects women. Learn more about what it means to have intrinsic eczema and why it's difficult, without a doctor's diagnosis, to tell the symptoms apart from allergic eczema. "Intrinsic eczema" is a medical term used by some skin professionals to describe a type of eczema that isn't related to criteria commonly seen in this skin disease, per 2015 research . These criteria include: The terms "intrinsic" and "extrinsic" were first used to distinguish between allergic and nonallergic sources of asthma, respectively. However, describing eczema as intrinsic or extrinsic remains controversial among professionals because it can lead to confusi
