An injection made of a hydrogel containing stem cells could treat damaged tissue following a heart attack.

Testing a large library of compounds reveals an easy-to-make lipid that can carry genetic code into the lung to treat disease.

Magnetic field could boost blood vessel growth to regenerate damaged tissue.

A subset of fibroblasts located in small foci of tissue on the edges of extensive scarring produce a protein that protects against cell aging.

Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines.

Researchers have found a way to enhance radiation therapy using novel iodine nanoparticles.

Our brain has no lymphatic system; however, it does have fluid flow, which is believed to play a role in removing waste from the brain. However, the fluid's point of origin and fluid flow is still unclear. The “multi-scale stable isotopes imaging” project in Hokkaido University aims to solve this mystery using advanced technology. “We would not have been able to perform this study without Hokkaido University’s MRI technology and the isotope microscope,” said the project’s PI, Professor Kohsuke Kudo of the Department of Radiology, Faculty of Medicine.

The inaugural virtual edition of Singapore Health and Biomedical Congress will be held on 7 & 8 October 2021. Register and submit abstracts now.

A signalling protein thought to be able to treat liver damage in paracetamol toxicity could actually worsen it. Instead, Singapore scientists discovered, blocking its effects could be the way forward.

Cryo-electron microscopy and computer simulations uncover how a cellular protein helps transport omega-3 fatty acids to the brain and eye, with implications for drug development.

A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.

• Glioblastoma (GBM) is a highly aggressive type of brain cancer. Even with current standard of care, 50% of patients die within 15 months of diagnosis. • This complex cancer is difficult to treat due to its location, structure, ability to spread quickly, high recurrence rate and severely limited treatment options. • GBM tumours can look identical under the microscope but respond differently to the same treatment. • With a national grant of about S$10 million, researchers in Singapore are working with overseas collaborators to address these challenges and develop new diagnostic and treatment options so patients can receive effective targeted therapy.

Researchers at The International Islamic University Malaysia (IIUM) have developed an algorithmic approach to predict progression of a condition called pterygium, which involves abnormal tissue growth across the eye.

Researchers have observed DNA spooling and unspooling in real time using CRISPR to attach fluorescent tags to very specific DNA points in living cells.

A simple tool allows researchers to track how different subpopulations of the Plasmodium knowlesi parasite are changing over time.

A spray-on magnetic coat turns any object into a robot controlled by a magnetic field. The biocompatible robots can walk, crawl and roll, and switch motions on demand.

A spinning toy meets hydrodynamics and sets point-of-care diagnostics in motion.

The trick to extremely thin supercapacitors with improved performance is spraying graphene ink at an angle.

First-of-its-kind in Singapore, the clinical trial will test a technology that enables specific cell therapy products to be manufactured for use in patients.

A mitochondrial peptide called MOCCI has a surprising sidekick, and they work together to regulate inflammation and immunity, Singapore researchers reveal.

A five-year study in Singapore has highlighted that chronic wounds among patients with diabetic foot ulcers and bed sores led to longer hospital stays.

New national body established to further research insights, improve patient outcomes and create new economic opportunities for the biomedical technology industry.

Scientists in Japan have developed and tested a novel probiotic formulation to control severe diarrhea in calves, ensuring their health and reducing mortality, and in turn reducing economic loss.

A series of studies led by HKBU researchers have revealed that hyocholic acid and its derivatives (collectively known as HCAs), a component of bile acids that facilitate fat digestion, are a promising risk indicator of type 2 diabetes. The strong efficacy of HCAs in regulating blood glucose levels and protecting against diabetes has also been uncovered.

Researchers reveal through a systematic review of 158 articles detailing quality improvements in pediatric intensive care units mainly throughout North America and the U.K. that despite having a median score of 11.0 on the Quality Improvement Minimum Quality Criteria Set, only 17% of them were considered high quality by achieving a 14-16 score, and only 5% cited Standards for QUality Improvement Reporting Excellence (SQUIRE) guidelines for reporting quality improvement works.

Multi-country trial finds low-cost intervention to improve hypertension management in rural communities is cost-effective. Consisting of home visits by community healthcare workers, physician training and coordination with public health care infrastructure, the intervention can be scaled up in low- and middle-income countries.

An ‘eat-me’ signal displayed on cell surfaces requires activation of a lipid-scrambling protein by a nuclear protein fragment.

Professor David Matchar and his team from the Health Services and Systems Research (HSSR) Programme at Duke-NUS bagged two prestigious awards at the International Stroke Conference 2021, held virtually on 17-19 March, 2021.

Through a series of experiments using nasal polyp organ culture and mouse models of restraint stress, researchers unveil relationship between presence of corticotropin-releasing stress hormone and increase in and degranulation of allergy-causing mast cells.

Study shows that antibody longevity varies widely from 40 days to as long as several decades and not everyone who has recovered from COVID-19 is immune from reinfection. Individuals with low levels of neutralising antibodies may still be protected if they have robust T-cell immunity. Blood tests and a computer algorithm suggest annual vaccinations might be needed for some individuals to prevent future outbreaks of COVID-19.
