Researchers show potential of biomimicry to grow prevascularized tissues for cardiac patches

A team led by Feng Zhao, associate professor of biomedical engineering at Michigan Technological University, recently published two new papers on best practices in engineering prevascularized tissues.

Researchers develop new strategy to treat sickle cell disease and beta thalassemia

Researchers at Dana-Farber/Boston Children's Cancer and Blood Disorders Center and the University of Massachusetts Medical School have developed a strategy to treat two of the most common inherited blood diseases -- sickle cell disease and beta thalassemia -- applying CRISPR-Cas9 gene editing to patients' own blood stem cells.

Lab-grown blood vessels provide hope for dialysis patients

Research published this week describes how lab-grown blood vessels were transformed into living tissue when grafted into dialysis patients needing replacement blood vessels.

Gene transfer technique can combat diabetes-linked heart dysfunction

Researchers with the VA San Diego Healthcare System and the University of California San Diego have shown that a gene transfer technique can combat heart dysfunction caused by diabetes.

U of G study beginning to unravel mystery of hagfish’s zombie hearts

They are the scavengers of the deep and the dead. Hagfish are slimy bottom-dwellers that live off the carcasses of dead sea creatures and thrive in deep waters where oxygen is hard to come by. In fact, their hearts can keep on beating for 36 hours without any oxygen, making hagfish a champion among anoxia-tolerant fish.

Study describes new muscular disease caused by mutation in myoglobin gene

Researchers of the Bellvitge Biomedical Research Institute led by Dr. Montse Olivé have described in Nature Communications a new muscular disease caused by a mutation in the myoglobin gene.

Researchers discover underlying cause of hereditary muscle disease

Researchers at Karolinska Institutet have discovered the underlying cause of a hereditary muscle disease first characterised in a Swedish family in 1980. It proves to be the first identified disease caused by defective myoglobin, the protein that transports oxygen in muscle cells.

VCU researchers home in on microRNA processing for new cancer therapies

More than a decade of research on the mda-7/IL-24 gene has shown that it helps to suppress a majority of cancer types, and now scientists are focusing on how the gene drives this process by influencing microRNAs.

Scientists identify common genetic variants associated with post-stroke recovery

Our genes may have a bearing not only on our stroke risk, but probably also on how well we recover after stroke. For the first time, in international collaboration, scientists at the University of Gothenburg and elsewhere have identified common genetic variants that are associated with outcome after ischemic stroke.

Synthetic peptide appears to disrupt inflammation and protect kidneys from nephritis

A synthetic peptide appears to directly disrupt the destructive inflammation that occurs in nephritis, enabling the kidneys to better recover and maintain their important functions, investigators report.

Recurrent pregnancy loss may be caused by sperm DNA damage, finds study

Some cases of recurrent pregnancy loss may be caused by sperm DNA damage in the male partner, rather than by a problem in affected women, according to research to be presented Sunday, March 24 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

High-fat, high-sugar diet in mouse mothers causes problems in the hearts of offspring

A diet high in fats and sugars is known for its unhealthy effects on the heart. Scientists now have found that a high-fat, high-sugar diet in mouse mothers before and during pregnancy causes problems in the hearts of their offspring, and that such problems are passed down at least three generations, even if the younger generations only eat a standard mouse chow diet.

Study provides new insight into blood cell and immune cell production

A healthy adult makes about 2 million blood cells every second, and 99 percent of them are oxygen-carrying red blood cells. The other one percent are platelets and the various white blood cells of the immune system.

Brain process common to sleep and aging discovered

Oxford University researchers have discovered a brain process common to sleep and ageing in research that could pave the way for new treatments for insomnia.

Pharmaceutical and personal care products may result in new contaminants in waterways

When you flush the toilet, you probably don't think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean.

Toilet seat heart monitoring system

Researchers have made a gadget that could fit on top of a normal toilet seat and it can also measure the heart beat, blood pressure, blood levels of oxygen and other parameters. This means that this device could potentially detect heart disease victims by catching early signs of heart problems and save lives say researchers.

Scientists grow most sophisticated brain organoid to date

Researchers at Cambridge Biomedical Campus have grown the most sophisticated brain organoid to date, providing new opportunities for scientists to understand human brain development and neurological disorders.

Study examines impact of high altitude exposure on memory

Oxygen is essential for maintaining normal human brain function, and living at high altitudes can lead to deficits in cognition such as attention and memory.

Researchers discover previously unknown mechanism by which cells can sense oxygen

Researchers from the University of Oulu and Harvard University have found a previously unknown mechanism by which cells in the body sense oxygen. Lack of oxygen had a direct influence on the functioning of genes, and prevented cell differentiation.

Mild sleep apnea during pregnancy changes sugar levels and may affect infant growth patterns

A study conducted by Sarah Farabi, PhD, RN, while she was a post-doctoral fellow working with Dr. Teri Hernandez at the University of Colorado College of Nursing and School of Medicine in 2018 found that mild sleep apnea changed sugar levels during pregnancy and was connected to infant growth patterns related to increased risk of obesity.
