Low-Frequency Ultrasound Can Increase the Amount of Oxygen in the Blood
A team of scientists from Kaunas University conducted research that unveiled the impact of low-frequency ultrasound on blood parameters. The findings suggest that the influence of ultrasound on hemoglobin can enhance the transfer of oxygen from the lungs to the body’s tissues. Blood – artistic visualization. The study involved the analysis of 300 blood samples...

Are your organs ageing well? The blood holds clues
One organ in a person’s body can age faster than the rest — with implications for health and mortality. Max Kozlov Scientists studied more than 5,000 people to understand variation in the ageing of individual body organs.Credit: Christopher Furlong/Getty As people age, their cells undergo a raft of biochemical changes that lead to organ damage...

Stem cell research could enable blood to be made in other parts of the body
by Nancy Fliesler, Children’s Hospital Boston Graphical abstract. Credit: Developmental Cell (2023). DOI: 10.1016/j.devcel.2023.04.007 Our bodies make blood in a specialized niche—a “nursery” within our bone marrow that nurtures blood stem cells so they can replicate and make different kinds of blood cells. The lab of Leonard Zon, MD, has even shown how blood stem cells, once they...

How drugs get into the blood?
Computer simulations have helped researchers understand how pharmaceutically active substances cross cell membranes. These findings can now be used to discover new drug candidates more efficiently. There is a need for new drugs. For example, many antibiotics we have been using for a long time are becoming less effective. Chemists and pharmaceutical scientists are frantically searching for new active...

New biomarker test can detect Alzheimer’s neurodegeneration in blood
by University of Pittsburgh Credit: Pixabay/CC0 Public Domain A group of neuroscientists led by a University of Pittsburgh School of Medicine researcher developed a test to detect a novel marker of Alzheimer’s disease neurodegeneration in a blood sample. A study on their results was published today in Brain. The biomarker, called brain-derived tau, or BD-tau, outperforms...

The key to new lupus treatment lies in the blood
SINGHEALTH Singapore, 14 December 2022 — A new study has shown that restoring the balance of a protein in blood may be a promising treatment option for systemic lupus erythematosus, or lupus, an incurable autoimmune disease. The protein, CXCL5, helps to regulate the immune system through neutrophils, a type of white blood cell. In patients with...
