Researchers from Osaka University have developed a skin-like device to measure brain activity via electroencephalography, which uses electrodes to measure electrical activity on the scalp (reflecting underlying brain activity). The device has other useful applications, such as measuring heart rate and blood oxygen levels. Wearable devices that can remotely assess brain health in everyday settings are likely to improve healthcare for millions of people worldwide.

Researchers from Osaka University have shown that deficiency of the protein Favine can lead to accelerated development of atherosclerosis. Loss of Favine in a mouse atherosclerosis model also led to calcification and thrombus development in the blood vessels of the mice. Prior to this, no mouse models for calcification or thrombus formation existed, hindering atherosclerosis research. This work also identifies Favine and its downstream signaling pathway, known as MEF2C-KLF2, as potential therapeutic targets for atherosclerosis.

The National Health Innovation Centre, Singapore (NHIC) has launched a Clinical Innovation and Adoption Initiative to nurture promising healthtech projects for adoption and scaling across healthcare clusters in Singapore.

Researchers from Osaka University have found that the Vibrio cholerae colonization factor TcpF forms a flower-shaped trimer to specifically bind to the minor pilus protein TcpB resulting in secretion by the type 4 pilus secretion system into the extracellular space. This finding could help lead to the development of a novel anti-adhesive drug that selectively interrupts the TcpF-TcpB interaction, which may replace antibiotics in the treatment of cholera.

Researchers from Osaka University have developed a computational analysis tool called CAPITAL for comparative analysis of single-cell RNA sequencing data with complicated branching trajectories. As cells undergo a dynamic process, they can be placed on a “pseudotime trajectory” to analyze the gene expression changes throughout the process. While previously only straightforward linear trajectories could be compared, CAPITAL is proven to be able to accurately compare branching trajectories, significantly advancing the field of high-throughput single-cell sequencing.

The SARS-CoV-2 Omicron variant escapes the immune response better than its coronavirus ancestors, but has also facilitated our transition to a society that can live with COVID-19.

Researchers from Osaka University have found that serum albumin interferes with β2m amyloid fibril formation through macromolecular crowding. Monitoring serum albumin concentrations could therefore help prevent patients from developing dialysis-related amyloidosis, a serious complication of long-term dialysis.

A pathway that malfunctions in advanced non-alcoholic fatty liver disease could be fixed with the aid of spermidine, a compound naturally found in bodily cells and certain whole foods.

Scientists have uncovered how Coxsackievirus B3, the most common cause for viral heart inflammation, takes advantage of a specific heart sensor to trigger chronic inflammation that can lead to heart failure.

Osaka University researchers identified the specific protein complex that recognizes when cellular organelles called lysosomes become damaged. When this occurs, the CUL4A protein complex transfers a molecular tag, called polyubiquitin, to a lysosomal protein known as LAMP2. WDFY1, another protein in the complex, is able to recognize and interact with LAMP2. These initial steps are critical to beginning a process called lysophagy, in which these damaged lysosomes are cleared away by the cell.

Cellular structures called mitochondria depend on microproteins to assist and control the assembly of a protein chain that extracts energy from nutrients, according to a new study by scientists in Singapore.

A commentary in Nature Medicine advocates the proper application of artificial intelligence in healthcare and warns of the dangers when machine learning algorithms are misused.

An estimated 1208 excess suicide deaths for men and 1825 for women were recorded during the COVID-19 Pandemic in Japan through December 2021, with the impact being greatest in women and younger age groups.

While the primary site of SARS-CoV-2 infection is in the nose, most antiviral immunity studies have been performed with peripheral blood. T-cell analysis of nasal swab samples suggests getting infected with SARS-CoV-2 following vaccination could confer potentially more robust, nasal-based immunity.

Tohoku University scientists in Japan have made a scaffold that supports the growth of new bone in large jaw defects in mice. Their findings, published in the journal PNAS Nexus, bring scientists one step closer to addressing the issues currently facing the treatment of large jaw bone defects, especially in the elderly.

Immunity in Chronic Hepatitis B and innovative treatment development

A group of researchers in Thailand has replicated "Hydroxy-xanthones", the vital extracts rich in antioxidants found in mangosteen peels that kill germs and halt infections in the intestinal mucosa. It hopes to expand to include health products for humans and animals in the future.

A study led by researchers from Hong Kong Baptist University (HKBU) has demonstrated that a multifunctional organic compound named F-SLOH has the potential to treat Alzheimer’s disease (AD) at an early stage. The team found that it can inhibit the aggregation of amyloid-beta (Aβ), and reduce the hyperphosphorylation of tau proteins and neuroinflammation in the brain to improve the pathological features of AD. The findings have been published in the international academic journal Redox Biology.

Takeda’s tetravalent dengue vaccine (TAK-003) is now the only dengue vaccine approved in Indonesia for use regardless of previous dengue exposure and without the need for pre-vaccination testing. This approval marks Takeda’s first marketed vaccine outside of Japan.

Researchers led by Osaka University shed light on a metabolic network integrated by an oral microbe Fusobacterium nucleatum (F. nucleatum). Analysis of co-cultures of F. nucleatum with other commensal oral bacteria revealed that metabolic cross-feeding enables F. nucleatum to increase the production of the polyamines putrescine and cadaverine, thereby promoting the development of periodontitis. The nutritional interactions of F. nucleatum may serve as potential targets for the development of new methods to prevent periodontal disease.

Adults self-report their pain on a one to 10 numerical score, while children can point to an equivalent face scale — from a green smiling face to a red crying face — to indicate their pain. Newborns, however, cannot say a number or point to a face, leaving it up to their caregivers to identify and evaluate any pain they may be in. Until the turn of this century, a significant number of clinicians did not recognize that neonates could even experience pain, resulting in infrequent, nonstandard training for medical workers. Now, researchers are reporting that a flexible e-learning program improves neonate pain management knowledge and skills for nurses.

Osaka University researchers used a large dataset of trauma patients in Japan to determine the characteristics and biomarkers most strongly associated with mortality risk by employing machine learning methods. This work may help improve the practice of emergency medicine.
