Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

Enzyme released by immune cells may play role in depression

Mount Sinai researchers have shown for the first time that immune cells called monocytes, derived in the bone marrow and released into the bloodstream, can be drawn during stress into sites in the brain that control emotional behaviors.

Study discovers a direct connection between the brain and its surrounding environment

In a recent study of the brain's waste drainage system, researchers from Washington University in St. Louis, collaborating with investigators at the National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institute of Health (NIH), discovered a direct connection between the brain and its tough protective covering, the dura mater.

Doppler ultrasound detects placental issues in small babies, study finds

A Doppler ultrasound that measures the blood flow of small unborn babies can reveal whether or not the placenta is working properly. In case of repeated deviations from these Doppler measurements, additional monitoring of the unborn baby is necessary.

Decoding cancer's spread: Epigenetic switch controls metastasis formation

Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University investigated in mice how spreading tumor cells behave at the site of metastasis: Some tumor cells immediately start to form metastases.

CRISPR-Cas9 gene-editing tool repairs defective T cells to treat rare hereditary disease

Some hereditary genetic defects cause an exaggerated immune response that can be fatal. Using the CRISPR-Cas9 gene-editing tool, such defects can be corrected, thus normalizing the immune response, as researchers led by Klaus Rajewsky from the Max Delbrück Center now report in "Science Immunology."

New study identifies key role of microRNA-29 in scar-free wound healing

New findings in The American Journal of Pathology, published by Elsevier, report that a class of small RNAs (microRNAs), microRNA-29, can restore normal skin structure rather than producing a wound closure by a connective tissue (scar).

Resistance training can help lower risk factors for cardiovascular disease

A recent scientific statement from the American Heart Association suggests that resistance training is at least as safe as aerobic exercise for those with heart disease and other health conditions, and for most people can provide similar or additive benefits in lowering risk factors for cardiovascular disease.

New scientific statement outlines recommendations for diagnosing, managing cerebral venous thrombosis

A new scientific statement from the American Heart Association emphasizes the need to increase patients' and physicians' awareness of cerebral venous thrombosis (CVT) to improve the recognition of this condition and initiate prompt medical treatment.

Groundbreaking technology shows immense potential for treating ischemic retinopathy

A groundbreaking technology with immense potential in treating ischemic retinopathy in premature infants and diabetic patients has been developed by Professor Byoung Heon Kang and his research team in the Department of Biological Sciences at UNIST, in collaboration with Professor Dong Ho Park's team at Kyungpook National University Hospital. Ischemic retinopathy, characterized by the breakdown of the blood-retinal barrier and abnormal blood vessel growth, often leads to vision impairment and loss.

Stromal cells may be useful in assessing prostate tumors' potential to spread

Non-cancerous cells called stromal cells, which are found in and around prostate tumors, may be useful in assessing these tumors' potential to spread, and may even be targets for future prostate cancer treatments, according to a study led by researchers at Weill Cornell Medicine.

Childhood dietary patterns influence arterial stiffness in adolescence

Diets high in calories, fat and sugar in childhood can cause damage to blood vessel function, known to heighten the risk of early heart attacks and strokes, as early as adolescence according to research funded by the British Heart Foundation (BHF).
