Science has not been able to create a substitute for human blood

Science has been able to create and employ a number of medical marvels, such as the artificial heart and synthetic insulin. But not a substitute for human blood.

Artificial sweetener derivatives show improved activity against tumor-associated enzymes

Saccharin received a bad rap after studies in the 1970s linked consumption of large amounts of the artificial sweetener to bladder cancer in laboratory rats. Later, research revealed that these findings were not relevant to people.

Catastrophic macropinocytosis may aid in cancer treatment

In laboratory experiments, a metabolic inhibitor was able to kill a variety of human cancer cells of the skin, breast, lung, cervix and soft tissues through a non-apoptotic route -- catastrophic macropinocytosis.

A future approach to diabetes care

In Belize, where diabetes is rampant, patients need insulin every day to maintain proper blood sugar levels. But if people lack electricity or a refrigerator, they cannot store insulin at home.

Scientists use blue mushroom dye to develop fluorescent tool for detecting reactive oxygen species

A new fluorescent tool for detecting reactive oxygen species based on a chemical found in mushrooms has been developed by scientists at the University of Bath.

Researchers identify novel genetic signature with prognostic value for certain breast cancers

Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases.

Scientists reveal brain mechanisms and functional regions that underlie confirmation bias

An international research team comprising neuroscientists at Virginia Tech, University College London and the University of London revealed brain mechanisms and functional regions that underlie confirmation bias -- a phenomenon where people strongly favor information that reinforces their existing opinions over contradictory ones.

Biologists discover that Savannah monitor lizards have hybrid lung structures

Take a deep breath in. Slowly let it out.

Paramedic breathing tube insertion on first attempt could save lives of cardiac arrest patients

A newer breathing tube could save the lives of more than 10,000 sudden cardiac arrest patients a year for a simple reason: it's easier than standard intubation to insert on the first try, according to researchers from The University of Texas Health Science Center at Houston.

New methodologies could help premature babies breathe easy

When a premature baby is born, the immediate challenge is to ensure it breathes easily without outside help. A new study shows that by carefully supplying 100% oxygen to these fragile scraps of humanity, independent breathing can be initiated much faster.

Researchers examine p53-deficient colon cancer cells to identify how p53 impacts metabolic adaptation

Colon cancer cells deficient in p53, one of the most important control proteins in cell growth, activate a particular metabolic pathway to adapt to the lack of oxygen and nutrients inside the tumor. Statins, which are often prescribed to lower cholesterol, block this metabolic pathway and cause the cancer cells to die, as scientists from the German Cancer Research Center have now discovered.

Researchers making major inroads into finding the cause of different diseases

Australian researchers are making major inroads into finding the cause of heart disease, Alzheimer's, cancer, diabetes and other diseases after discovering a further 148 proteins affected by oxidative stress in the human body.

'Fuzzy logic' alarm system may help nurses in NICU predict impending catheter infusion failure

A "fuzzy logic" alarm system may help nurses in the neonatal intensive care unit predict impending catheter infusion failure – and prevent complications in critically ill newborns, reports a study in the October issue of Advances in Neonatal Care, official journal of the National Association of Neonatal Nurses.

Researchers create 'lab on a chip' devices to help medics monitor patients’ health in real-time

Researchers have identified a way of allowing medics to use tiny laboratories to monitor their patients’ health in real-time and deliver a greater level of personal care than ever before.

Water births are safe and cause fewer first and second-degree tears, shows study

A new study found that water births are no more risky than land births, and that women in the water group sustain fewer first and second-degree tears.

New startup aims to prevent reperfusion-related organ damage after liver transplant

Roughly 65 years ago, the first human organ transplant was successfully performed. A decade later, heart and liver transplants became possible. Now, a startup founded by researchers from the Medical University of South Carolina and elsewhere hopes to bring about the next major breakthrough.

Fetal heart rate could predict future heart health of babies

Changes in heart rate due to low oxygen conditions experienced by the fetus during pregnancy could predict the future heart health of babies, suggests research published today in The Journal of Physiology.

Isansys Lifecare announces partnership with WH Tech in Australia

Isansys Lifecare, a global digital health technology company, is delighted to announce its partnership with WH Tech Pty Ltd, Australia’s leading importer of wearable connected healthcare.

Perinatal maternal antibiotic exposure may impair lung development in premature infants

New research in mice suggests that exposure to antibiotics before birth may impair lung development in premature infants. The study, the first to explore the gut-lung axis in prematurity, is published ahead of print in the American Journal of Physiology—Lung Cellular and Molecular Physiology and was chosen as an APSselect article for December.

Ommochromes have antimicrobial, antioxidant and antimutagenic properties

Ommochromes, the pigments that colour the skin of squids and other invertebrates, could be used in the food and health sectors for their antioxidant and antimicrobial properties. This is confirmed by the analyses carried out by researchers from the University of Sonora in Mexico and the Miguel Hernández University in Spain.
