Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
Patients with a high risk of dying after surgery, including those with multiple chronic diseases, benefit from undergoing general or vascular procedures at a major teaching hospital as opposed to a non-teaching hospital, according to a study from researchers at Penn Medicine and the Children's Hospital of Philadelphia.
In what sounds like a scene from a science fiction movie, researchers in 2005 stitched together old and young mice so they shared a circulatory system.
A new Taiwanese study presented on October 14, 2019, at the Annual Meeting of the American Academy of Ophthalmology, reports that macular edema in diabetes occurs more often in those who have severe sleep apnea.
A new study presented at the Annual Meeting of the American Academy of Ophthalmologists (AAO) on October 14, 2019 reports an astonishing 95.% yield when artificial intelligence (AI) is used to screen a real life population for diabetic retinopathy.
A major UConn School of Medicine study published in the American Heart Association's flagship journal Circulation shows that more aggressively controlling daily blood pressure in older adults can improve brain health.
Each year, heart attacks kill almost 10 million people in the world, and more than 6 million die from stroke. A heart attack is caused by a clot that blocks the artery blood flow. Unirrigated tissues are deprived from the oxygen that is carried by the blood. Under these conditions, the affected tissues undergo a rapid necrosis.
Brain concussion occurs when the soft cottage cheese-like brain tissue is slammed against the hard skull surface, sustaining transient and reversible injury which causes brain dysfunction for a period.
A new study published in the journal Brain shows that microbleeds appearing after trauma can cause patients with head injury to have poor outcomes. Advanced imaging techniques were used to establish this finding.
The effects of a traumatic brain injury are pretty clear – problems with memory, headaches, and emotions – but what's unclear is the underlying pathological causes for those symptoms.
Traumatic brain injuries, including concussions, can be caused by anything from sports injuries to battlefield trauma.
In Germany alone there are around 400,000 patients who suffer from chronic inflammatory bowel diseases. For the first time, researchers at Universitätsklinikum Erlangen have discovered that dysfunctions in blood vessels play a significant role in the development of such diseases.
Devices coated with a drug called paclitaxel that are used for widening blocked arteries in legs and feet are safe and not linked to an increase in deaths, according to a study of nearly 65,000 patients, published in the European Heart Journal today (Wednesday).
In breast cancer patients with metastatic disease, bone is the most common site of metastasis and the most common site of first distant relapse, with roughly half (48%) of breast cancer patients developing bone metastases after treatment.
Blocking the mineralocorticoid receptor (MR)- a protein that helps maintain normal levels of salt and water in the body- in immune cells may help reduce the risk of heart attack and stroke by improving blood vessel health.
Within minutes of breaking a bone, the body begins to repair itself.
3D printing leader Stratasys Ltd. is further extending its commitment to the medical industry with the new J750™ Digital Anatomy™ 3D Printer. Designed to replicate the feel, responsiveness, and biomechanics of human anatomy in medical models – the system improves surgical preparedness and training while helping bring new medical devices to market faster.
Ever since three US-based researchers working independently unveiled the role of nitric oxide in mediating blood vessel dilation, endothelial cell contraction and smooth muscle relaxation, their discoveries have served as a basis for novel treatments for high blood pressure and erectile dysfunction, among other conditions.
A blow to the head or powerful shock wave on the battlefield can cause immediate, significant damage to a person's skull and the tissue beneath it.
Every tissue in the human body has an immune cell in it called a macrophage. Macrophages play important roles in the immune system's initial response to bacteria, viruses and wounds.
Researchers at the National Institutes of Health (NIH) have developed a unique, improved lentiviral vector for use in gene therapy for sickle cell disease.
