Duke-NUS is working with the Bill and Melinda Gates Foundation to develop the Asia Pathogen Genomics Initiative (APGI) to improve regional genomic surveillance and sequencing capacity. New Centre for Outbreak Preparedness will support APGI and work closely with national and global partners to enhance regional capacity to predict, prepare and respond to future health threats.

Potential of a novel therapeutic strategy for rheumatoid arthritis by UHRF1 stabilization We identified an epigenetic regulator UHRF1 that suppresses various pathogeneses in rheumatoid arthritis. The UHRF1 expression level in synovium showed a negative correlation with the severity of pathogenesis in patients with rheumatoid arthritis and mouse arthritis models. In addition, stabilization of the UHRF1 expression achieved improvement of the arthritis pathology. Our results indicate that the stabilization of the UHRF1 protein is a potential therapeutic strategy for rheumatoid arthritis patients.

Partnership seeks to deepen symbiotic industry-academia collaborations in applied research and talent upskilling. First-of-its-kind made-for-Asia sustainable R&D to develop kale stems as prebiotics

Scientists at Osaka Metropolitan University utilized a Japan-developed, objective, and simple nutritional indicator called the Nutrition Risk Index (NRI) to unveil a long-suspected yet unverified relationship between sarcopenia and malnutrition in end-stage kidney disease patients. Their findings confirmed that malnutrition contributes to sarcopenia, which can be detected through NRI.

A research team led by Hong Kong Baptist University (HKBU) has found that a proteolytic enzyme called membrane-type 1 matrix metalloproteinase (MT1-MMP) plays an important role in the regulatory mechanism of fullness, or satiety, and it could serve as a promising potential drug target for the management of obesity.

Among anesthetics, ketamine has a unique effect: it also acts as an antidepressant. A research team led by Osaka Metropolitan University Professor Makoto Kondo linked ketamine to brain regulation of IGF-1, which works independently of other ketamine-associated factors. The discovery may help untangle ketamine’s positive and negative effects, allowing future drug development to target IGF-1 directly.

The antibiotic rifampicin is shown as a potential medicine for preventing Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal dementia (FTD).

A study by Japanese researchers showed that getting a mild case of COVID-19 doesn’t translate to lower chances of becoming a long-hauler. And that sex and the presence of long-term symptoms are risk factors for post-COVID psychological distress.

Adenosine triphosphate (ATP) secreted from sensory neuron-interneuron crosstalk is key to the spreading of inflammation across joints, acting as a neurotransmitter and inflammation enhancer.

Giants in History: Thai physician and conservationist Boonsong Lekagul (15 December 1907 – 9 February 1992) made major contributions to the preservation of his country’s wildlife by founding organizations including the Association for the Conservation of Wildlife (ACW), writing about Thailand’s natural heritage, and supporting conservation initiatives.

Strokes have a debilitating effect on quality of life; the combination of cognitive and physical effects can be especially devastating. A new study from Osaka Metropolitan University Graduate School of Rehabilitation Science showed that moderate to severe hand and arm paralysis was dramatically improved with the use of robotic therapy, for chronic stroke patients with upper extremity hemiplegia in Japan, as reported in the journal Stroke.

Giants in History: Ground-breaking cancer researcher Kamal Jayasing Ranadive (8 November 1917 – 11 April 2001) advanced the understanding of the causes of leukaemia, breast cancer and oesophageal cancer through the use of animal models.

As COVID-19 continues to spread across the world, there is mandatory 7 to 21-day quarantine for travellers who arrive in Hong Kong and Mainland China from overseas. Since self-isolation may affect people’s emotional health adversely, Lingnan University (LU)’s Wofoo Joseph Lee Consulting and Counselling Psychology Research Centre (WJLCCPRC) has designed a self-assessment questionnaire and intervention exercise to help people in quarantine cope better psychologically.

A new report by the InterAcademy Partnership (IAP) highlights practical recommendations for improving the uptake of vaccines.

Hokkaido University researchers have shown how chronic pain leads to maladaptive anxiety in mice, with implications for treatment of chronic pain-related psychiatric disorders in humans.

Scientists discovered that intramuscular fat levels are indicative of heart health. Measurements of intramuscular fat in 93 heart failure patients’ thighs showed patients with high intramuscular fat levels were at greater risk of rehospitalisation, despite no significant differences in conventional heart health criteria. These findings enable new approaches for treating heart failure, a growing concern in Japan’s ageing society.

Genome profiling of Staphylococcus argenteus strains unveiled cross-contamination among Japanese retail foods and slaughterhouses.

In line with globally recommended practices to reduce the dietary risk of non-communicable diseases (NCDs), the Sri Lankan government implemented a traffic-light labelling (TLL) system for sugar-sweetened beverages (SSB) in August 2016. The purpose of the regulations was to educate the public on the sugar content in SSBs to promote healthy diets in Sri Lanka and reduce NCDs associated with a high sugar intake. It is timely to assess the effectiveness of TLL in encouraging healthier food choices. Based on an ongoing IPS study, this blog discusses consumers’ knowledge of TLL and how it impacts their SSB choices.

Exercising during pregnancy bestows a wealth of benefits upon a child. New research suggests that exercise may also help reduce the offspring’s chances of getting type 2 diabetes. Researchers uncovered how SOD3, a key protein released by the placenta after exercise, improves the metabolic health of offspring and negates the impacts of maternal obesity and poor diets.

Osaka City University* study suggests memories are formed through an integration across brain regions via burst activity in amygdala-prefrontal neuronal ensembles during memory acquisition, and then hippocampal-prefrontal synchrony during post-experience sleep.

Mycobacteria are a group of pathogenic bacteria that cause diseases like leprosy and tuberculosis in humans. Now, a new study by scientists at Hiroshima University finds that mycobacteria are associated with red blood cells at lung infection sites, an interaction that has escaped scientific notice for 140 years since the discovery of the organism causing tuberculosis.

Chemotherapy is known for its painful side-effects. It also has limitations when the cancer has metastasized to the lymph nodes. The lymphatic drug delivery system, where anticancer drugs are injected directly into the sentinel lymph nodes under ultrasound guidance, offers an alternative to conventional chemotherapy. Researchers from the Tohoku University Graduate School of Medical Engineering found the optimal osmotic pressure and viscosity ranges, significantly improving the antitumor effect.

Prof. Takashi Takebayashi and his colleague performed a retrospective analysis where they analysed the significance of varied assistance level when using robotic therapy among stroke survivors. They proved that the assistance level needs to be maximised for patients who had severe to moderate stroke whereas the assistance should be minimised for the moderate to mild stroke patients. They stressed on the need for future studies with more objective outcome tools and a larger sample using appropriate research methods.
