UrduResearchers have found a method using molecular profiling and machine learning to develop blood-based dietary signatures that more accurately predict both diet and the risk of cardiovascular disease and type 2 diabetes. They say the metabolic snapshot could allow those studying food science to better understand the implications of diet and nutrition on health.

Advancing new technologies to halt bleeding
The research arm of the U. S. Army has awarded Case Western Reserve University blood surrogate pioneer Anirban Sen Gupta a four-year, $2.5 million grant to advance and optimize his latest nanotechnology to stop bleeding from battlefield injuries.
The new technology devised by Sen Gupta and his team is called “SanguiStop.” It allows a clot-promoting enzyme called thrombin to be intravenously delivered in a targeted manner to a bleeding area—especially to the site of internal injuries.

TraumaChekTM: Next step in life-saving blood-assessment technology
Scientists at Case Western Reserve University are leading the development of TraumaChekTM, a hand-held medical device to quickly assess a wounded soldier’s critical clotting issues and other blood conditions in the battlefield. The new sensor, if successful and adopted in the field, would represent the next generation of their successful ClotChip®, which emergency workers can use to measure how well a patient’s blood may clot.

25-year-old University of Chicago Medicine research coordinator earns Diana Award for University Blood Initiative
University of Chicago Medicine clinical research coordinator Aviva Klein, 25, was named to the prestigious 2021 Diana Award Roll of Honour for her work creating the University Blood Initiative (UBI).
How a simple blood test can identify women at risk for preterm birth
One in ten babies is born prematurely in the United States, but a blood test during a routine prenatal visit could reveal if a woman is at risk of a preterm delivery, according to a Michigan State University researcher.
“Preterm births are common,” said Hanne Hoffmann, an assistant professor in the Department of Animal Science in the College of Agriculture and Natural Resources. “If we know the mother is at risk for a preterm birth, her doctor can monitor her more closely.”
Using Old and Young Blood to Study Age-related Muscle Loss
An innovative model using human blood samples to study muscle protein growth may help advance scientists’ understanding of age-related muscle loss.
New Microchip Sensor Measures Stress Hormones from Drop of Blood
A Rutgers-led team of researchers has developed a microchip that can measure stress hormones in real time from a drop of blood.

Taking new steps with artificial platelets
The National Institutes of Health (NIH) has awarded a $2.1 million, four-year research grant to Anirban Sen Gupta at Case Western Reserve University in Cleveland, Ohio, and collaborators at the University of Michigan and University of North Carolina, to advance the design of artificial platelets that can promote and stabilize clots to stop bleeding.
NUS scientists discover a new pathway essential for blood formation
Scientists from the National University of Singapore have discovered how a protein called Tip60 plays a vital role in the renewal of blood cells in the body. Without it, the stem cells that make new blood suffer catastrophic damage. This discovery could lead to better treatments for life-threatening blood-related diseases like leukemia.
Researchers create a tool that can pull an elusive COVID-19 marker from human blood
Researchers at Canada’s McMaster University and SQI Diagnostics have created a surface that repels every other element of human blood except a critical indicator of infection, opening a timely window for understanding the progress of COVID-19 in individual patients.
University Hospitals Becomes First Hospital in U.S. to Use New Blood Retrieval Device
This month, University Hospitals (UH) Harrington Heart & Vascular Institute became the first hospital in the U.S. to use the new blood retrieval device ProCell®.
MicroRNA Variation in Circulation Could Explain Sex Differences in Heart Health

Bat Tick Found for the First Time in New Jersey
A tick species associated with bats has been reported for the first time in New Jersey and could pose health risks to people, pets and livestock, according to a Rutgers-led study in the Journal of Medical Entomology. This species (Carios kelleyi) is a “soft” tick. Deer ticks, which carry Lyme disease, are an example of “hard” ticks.
The genetics of blood: a global perspective
To better understand the properties of blood cells, an international team led by UdeM’s Guillaume Lettre has been examining variations in the DNA of 746,667 people worldwide.
Dilated Blood Vessels in the Lung May Explain Low Oxygen Levels in Severe Cases of COVID-19
A new pilot study from the Icahn School of Medicine at Mount Sinai suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.
Ultrasound-Assisted Molecule Delivery Looks to Preserve Blood for Years
Blood can typically be stored for only six weeks after donation, but a potential solution attempts to dry blood by using a sugar-based preservative. New work in ultrasound technology looks to provide a path to inserting these sugars into human red blood cells, allowing the molecule trehalose to enter the cells and prevent their degradation when dried for preservation. The researchers discuss their work in this week’s Biomicrofluidics.
UCLA clinical trial tests convalescent plasma as a potential COVID-19 treatment
UCLA has joined a nationwide effort to study whether convalescent plasma collected from people who have recovered from COVID-19 may yield a treatment for the deadly virus.
Vitamin D Boosts Chances of Walking After Hip Fracture
Senior citizens who are not vitamin D deficient have a better chance of walking after hip fracture surgery, according to a Rutgers-led study. The findings in The American Journal of Clinical Nutrition suggest that vitamin D deficiency could limit mobility in older adults, said senior author Sue Shapses, a professor in the Department of Nutritional Sciences at the School of Environmental and Biological Sciences at Rutgers University–New Brunswick.
Robot Uses Artificial Intelligence and Imaging to Draw Blood
Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.
Blood Shortage on the Battlefield? Just Make It On-site
A new program launched by the Department of Defense could be the answer to blood shortages on the battlefield, other remote locations, and in hospitals. The Uniformed Services University of the Health Sciences’ 4D Bio3 On-Demand Blood Program, or 4D Bio3 Blood, has developed highly efficient protocols and technology to generate red blood cells from stem cells. A key part of this technology is large-scale cell expansion at low cost, producing sufficient red blood cells for treatment in trauma care. This technology is also being adapted to create neutrophils, ultimately allowing for whole blood transfusion using these methods in the future.
