Blood pressure

Source: Proceedings of the National Academy of Sciences Summary: A large team of researchers has developed a model that suggests it should be possible to create a cuffless, non-invasive blood pressure monitor based on measuring pulse waves. The current method of measuring human blood pressure is to place a pressurized cuff onRead More →

Cerebral

Source: University of California Summary: A team of researchers has provided, for the first time, evidence that blood deposits in the brain may not require a blood vessel tear. Bleeding in the brain, identified as cerebral microbleeds (CMB) on magnetic resonance imaging (MRI), are tiny deposits of blood in the brain that are associatedRead More →

Tannic acid

Source: The Korea Advanced Institute of Science and Technology (KAIST) Summary: A research team developed a heart-targeting drug delivery technology using tannin acid via intravenous systemic injection. This method can be applied to the development of a variety of new protein-based drugs. Cardiovascular-circulatory disease is currently the second leading cause ofRead More →

Omega-3 may prevent cancer

Source: University of Illinois at Urbana-Champaign Summary: Researchers report that a class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer’s growth and spread. In 2017, the research team identified a new group of omega-3 fatty-acid metabolites called endocannabinoid epoxides, or EDP-EAs. They found that these moleculesRead More →

GPR68

Source: The Scripps Research Institute Summary: Researchers have identified a protein, called GPR68, that senses blood flow and tells small blood vessels called arterioles when to dilate. Americans die of heart or cardiovascular disease at an alarming rate. In fact, heart attacks, strokes and related diseases will kill an estimated 610,000 Americans thisRead More →

Organs-on-Chips technology

Source: Cedars-Sinai Medical Center Summary: A new study has revealed that the human brain’s tiniest blood vessels can activate genes known to trigger spinal motor neurons, prompting the neurons to grow during early development. When a human embryo is about four weeks old, new blood vessels begin to surround a primitive column ofRead More →

Tunable microfluidic atherosclerosis model

Source: American Institute Of Physics Summary: Researchers have built a new device that’s especially good for modeling atherosclerosis – the constriction of blood vessels that’s the leading cause of heart attacks and strokes. Researchers usually turn to cultured cells on Petri dishes or experiments with lab animals to study diseases or test potential drug therapies. ButRead More →

Pericytes help in blood vessel dysfunction

Source: Medical University of South Carolina Summary: Researchers reported that pericytes, a type of cell on the brain’s blood vessels, grow into the empty space left when neighboring pericytes die. Such growth is a kind of brain plasticity. Pericytes are contractile cells that wrap around the blood vessels. They help bloodRead More →
