Researchers successfully implanted the first artificial tubular muscle in vivo

In January of this year, EPFL engineers announced in Advanced Science their concept of a novel cardiac assist device that is devoid of rigid metallic components. It consists of a soft, artificial muscle wrapped around the aorta that can constrict and dilate the vessel, ultimately enhancing the aorta's natural function and aiding the heart to pump blood to the rest of the body.

Rapid test kit for malaria delivers results in 30 minutes

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a test kit for malaria that delivers results in 30 minutes. The kit could facilitate the diagnosis of malaria in the field, as the equipment needed is anticipated to be lightweight, easy-to-use, and able to detect the disease in its early stages.

Convalescent plasma associated with better survival in blood cancer patients with COVID-19

Convalescent plasma therapy was associated with better survival in blood cancer patients hospitalized with COVID-19, especially in sicker patients. The findings by the COVID-19 and Cancer Consortium (CCC19) are newly published in the peer-reviewed journal JAMA Oncology.

Researchers demonstrate an alternative way to produce highly detailed images of the brain

The gold standard in functional brain imaging for over two decades, functional magnetic resonance imaging (fMRI) has transformed the landscape of research and clinical care. Yet, because of its cost and functional limitations, scientists have continued to look for new ways to see into the human brain.

Virginia Tech researcher receives $2.2 million to advance study on small 'fat burning' molecules

The liver is the most resilient organ in the human body. It can remove toxins from the bloodstream, recycle red blood cells, maintain sugar levels, and it can even regenerate itself. But, when a large amount of fat builds up in the liver, it becomes too inflamed to perform its crucial duties.

Study sheds new light on the mechanics and physics of blood clotting

Heart attacks and strokes -; the leading causes of death in human beings -; are fundamentally blood clots of the heart and brain. Better understanding how the blood-clotting process works and how to accelerate or slow down clotting, depending on the medical need, could save lives.

Researchers identify a novel link between aging, metabolism and anti-cancer T-cell function

MUSC Hollings Cancer Center researchers are finding solutions to the aging-related changes that reduce anti-cancer immunity. Besim Ogretmen, Ph.D., and colleagues found a novel link between aging, metabolism and anti-cancer T-cell function. Their work, published in Cell Reports, sheds light on an important pathway that cannot be ignored during cancer treatment.

Pitt researchers use a unique and powerful MRI device to study sickle cell disease

Sickle Cell Disease (SCD) is a genetically inherited group of red blood cell disorders. According to the CDC, an estimated 90,000 to 100,000 people in the United States live with this disease, and it disproportionately affects Black or African Americans; it occurs in roughly 1 in every 500 individuals in this demographic.

New study sheds light on why many COVID-19 patients suffer from hypoxia

A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues.

Malaria parasites may survive, replicate within the spleen of asymptomatic individuals, study suggests

Malaria, a disease caused mainly by the parasites Plasmodium falciparum and Plasmodium vivax, (P. vivax) is associated with over 400,000 deaths each year.

Researchers develop proof-of-concept treatment for blood disorders

Researchers at Children's Hospital of Philadelphia (CHOP) have developed a proof-of-concept treatment for blood disorders like sickle cell disease and beta-thalassemia that could raise hemoglobin levels by activating production of both fetal and adult hemoglobin.

Blocking TGFβ1 could improve hematopoiesis in AML patients, indicates study

Bone marrow failure due to acute myeloid leukemia (AML) is a significant factor behind the disease's high rate of morbidity and mortality. Previous studies in mice suggest that AML cells inhibit healthy hematopoietic (blood) stem and progenitor cells (HSPC).

Blocking ABCB10 protein in liver cells protects against high blood sugar, fatty liver disease

A new multi-institution study led by a team of researchers at the David Geffen School of Medicine demonstrated that blocking a protein called ABCB10 in liver cells protects against high blood sugar and fatty liver disease in obese mice.

Study shows how biases could be perpetuated by AI devices

Clinicians and surgeons are increasingly using medical devices based on artificial intelligence. These AI devices, which rely on data-driven algorithms to inform health care decisions, presently aid in diagnosing cancers, heart conditions and diseases of the eye, with many more applications on the way.
