NIH researchers develop 'placenta-on-a-chip' to study role of placenta in pregnancy

National Institutes of Health researchers and their colleagues have developed a "placenta-on-a-chip" to study the inner workings of the human placenta and its role in pregnancy. The device was designed to imitate, on a micro-level, the structure and function of the placenta and model the transfer of nutrients from mother to fetus. This prototype is one of the latest in a series of organ-on-a-chip technologies developed to accelerate biomedical advances.

New UT Southwestern research shows that exercise can improve diabetes control

Diabetics who exercise can trim waist size and body fat, and control blood glucose, even if they don't see cardiorespiratory benefits, new research by UT Southwestern Medical Center cardiologists shows.

High fructose consumption can lead to uncontrolled growth of cardiomyocytes, heart attack

'Walk through any supermarket and take a look at the labels on food products, and you'll see that many of them contain fructose, often in the form of sucrose (table sugar)' -- that's how Wilhelm Krek, professor for cell biology at ETH Zurich's Institute for Molecular Health Sciences, summarises the problem with today's nutrition.

New tissue 'scaffold' technology could one day help produce large organs

Scientists have developed a new tissue 'scaffold' technology that could one day enable the engineering of large organs. Research led by the Universities of Bristol and Liverpool has shown that it is possible to combine cells with a special scaffold to produce living tissue in the laboratory. It is hoped this can then be implanted into patients as a way of replacing diseased parts of the body.

Loyola patient celebrates 10th anniversary of heart and double-lung transplant

On March 20, Andrew Gaumer celebrated the 10th anniversary of his life-saving heart and double-lung transplant. On Mother's Day, his wife, Andrea, gave birth to their first child, a baby boy named Jude. And on June 21, Andrew will celebrate his first Father's Day - a milestone he once feared he would never see.

ALK1 protein determines the extent of breast tumour's spread in the body

For breast cancer to be fatal, the tumour has to send out metastases to other parts of the body. The cancer cells are spread via the blood vessels, and a research team at Lund University in Sweden has now proven that the protein ALK1 determines the extent of the tumour's spread in the body.

Completing sepsis resuscitation bundle in six hours after diagnosis

Blood poisoning, known as sepsis, is the most common cause of death in intensive care units, according to the National Institutes of Health. The body's immune response to fight the infection triggers inflammation that restricts blood flow and leads to multiple organ failure.

New study reports more practical approach to heal the heart after a heart attack

Stem cell have been the main focus of healing therapy research because they can morph into new cells, and using a patient's own stem cells will not induce an autoimmune response. For healing after a heart attack, the ideal time to administer these therapies is when reopening the clogged blood vessel because the heart is easily accessible. While stem cells show promise for heart attack treatment, the process of harvesting and reintroducing the cells—which can take days or weeks—is too slow for this window.

La Jolla Institute researchers identify molecular pathway that maintains Treg cells' function

Regulatory T cells (Treg cells) are part of the system of checks and balances that prevents the immune response from going overboard and causing autoimmune disease. Although critically important for shaping the immune response and maintaining self-tolerance, how they hold on to their immune-suppressive powers had remained unclear.

Researchers focus on novel techniques to combat global blood shortage

Red blood cells are the cells responsible for transporting oxygen to all the organs of the body. Red blood cells are the body's most common cell type: no less than 20 billion red blood cells die and are regenerated every day.

Fruit flies helping FAU researchers to discover novel genes responsible for neuroprotection

They're pesky and annoying when they get into your fruit, but Drosophila melanogaster, more affectionately known as the "fruit fly," are helping researchers at Florida Atlantic University to discover novel genes that are responsible for neuroprotection.

Triciribine drug may reverse progression of pulmonary fibrosis and pulmonary hypertension

Researchers at the University of Georgia have discovered that the drug triciribine may reverse or halt the progression of pulmonary fibrosis and pulmonary hypertension, two respiratory diseases that are almost invariably fatal.

New research shows that stem cells are sensitive to oxygen radicals and antioxidants

Stem cells are especially sensitive to oxygen radicals and antioxidants shows new research from the group of Anu Wartiovaara in the Molecular Neurology Research Program of University of Helsinki.

Researchers show how a new drug speeds tissue regeneration in animal models

The concept sounds like the stuff of science fiction: take a pill, and suddenly new tissues grow to replace damaged ones. Researchers at Case Western Reserve and UT Southwestern Medical Center this week announced that they have taken significant steps toward turning this once-improbable idea into a vivid reality.

Weill Cornell scientists reveal how XBP1 gene can trigger immune responses against ovarian tumors

Ovarian cancer shuts down immune system cells that would otherwise act as a first line of defense against the deadly tumor, Weill Cornell Medical College scientists report today. But a therapy that restores the cells' disease-fighting abilities could provide a powerful new strategy to attack the cancer, which kills more than 14,000 women each year.

Novel combination of non-toxic dietary and hyperbaric oxygen therapies doubles survival time in cancer model

A team of researchers from the Hyperbaric Biomedical Research Laboratory at the University of South Florida (USF) doubled survival time in an aggressive metastatic cancer model using a novel combination of non-toxic dietary and hyperbaric oxygen therapies.

Findings point to new therapy against prostate and other cancers

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found that a drug candidate with anticancer potential can be activated by one of the body's natural responses to cellular stress. Once activated, the agent can kill prostate cancer cells.

WMMC expands use of capnography to monitor patient's breathing to control pain after surgery

White Memorial Medical Center recently strengthened patient safety measures by expanding its use of capnography to monitor patients using patient-controlled analgesia (PCA) to regulate their pain after surgery.
