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.

Giants in History: The first Thai woman to receive a degree in medicine, Margaret Lin Xavier (29 May 1898 – 6 December 1932), is best remembered for her compassion towards her less privileged patients.

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.

The OWSD Early Career Fellowship is a prestigious award of up to USD 50,000 offered to women who have completed their PhDs in Science, Technology, Engineering and Mathematics (STEM) subjects and are employed at an academic or scientific research institute in one of the listed Science and Technology Lagging Countries (STLCs).

Reaction design framework proposed by computations leads to the discovery of a wealth of reactions, opening new paths for drug development.

Scientists at Duke-NUS Medical School, Singapore, have found that elevated blood levels of an amino acid called homocysteine correlate strongly with the severity of an advanced form of non-alcoholic fatty liver disease. They also found vitamin B12 and folic acid could potentially prevent and/or delay disease progression.

Researchers have discovered that vitamin K acts as a powerful antioxidant. It can inhibit ferroptosis, a type of cell death associated with Alzheimer’s disease and organ damage, by trapping lipid radicals. Furthermore, the team identified the long-sought-after vitamin K-reducing enzyme, the identity of which remained unknown for more than half a century.

The history of extracting chay root dye — a natural red colourant — from the chay plant (Oldenlandia umbellata) dates back to at least the seventeenth century. Read on to know more about the relevance of the dye in the textile dyeing practices of southern India.

Asia Research News monitors the latest research news in Asia. Some highlights that caught our attention this week are the discovery of an ancient palace that could be connected to Genghis Khan, the joy of letting your mind wander, and a wound dressing made from frog skin that promotes healing.

Osaka University researchers designed a silicon-based agent that successfully generated hydrogen continuously in the mouse gastrointestinal tract in an ulcerative colitis (UC) model. The hydrogen served as an antioxidant that could eliminate the reactive oxygen species shown to induce the chronic inflammation responsible for the damage and symptoms caused by UC. Mice given the agent had reduced hemorrhage, inflammation, and hyperexcitability in the brain area associated with visceral pain and discomfort. These results may help with the development of a novel treatment for UC.

The World Health Organization (WHO) welcomes the launch by Gavi, the Vaccine Alliance, of the landmark opportunity for countries to apply for funding to introduce, or further roll-out, the RTS,S/AS01 (RTS,S) malaria vaccine.

Cultured human skeletal muscle cells infused with serum from hibernating bears exhibited “muscle gain” confirming that these creatures’ ability to avoid muscular damage despite months of inactivity is in their blood.

An artificial intelligence (AI) algorithm trained to listen to patients pass urine is able to identify abnormal flows and could be a useful and cost-effective means of monitoring and managing urology patients at home. It is presented today at the European Association of Urology annual congress (EAU22), in Amsterdam.

Specialised physician training, nurse-led motivational conversations and follow-up with patients, and subsidy on combination medication significantly lowered BP among patients with uncontrolled hypertension, according to findings from Singapore.

Chula Engineering and Chula Medicine co-invent an innovative device for a rapid and accurate gastrointestinal cancer detection hoping to foster preventive medicine and reduce the number of cancer patients.

Researchers from Osaka University have found that infection with SARS-CoV-2 activates the expression of IRF1, a key regulator of insulin/IGF signaling in multiple tissues, leading to disruption of blood sugar metabolism and, in some cases, new onset of diabetes. Treating infected cells with hormonal factors that decreased IRF1 expression enhanced insulin/IGF signaling, suggesting that this approach could be used to mitigate some of the more severe side effects of COVID-19 in the future.

Automation in disease diagnosis is reliant on deep learning models that can accurately and efficiently identify measurements of tumors, tissue volume, or other sorts of abnormalities. Now, researchers from Tohoku University have unveiled a new, resource-light model capable of identifying many common eye diseases.

Researchers from Osaka University have found that nematodes can be coated with a protective hydrogel sheath that can be engineered to carry functional cargo. This system could potentially be developed to deliver anti-cancer drugs to tumors using worms with a natural predilection for human cancer cells.
