Osaka Metropolitan University researchers conducted a 5-year claims-based study of 655 non-frail or pre-frail older adults who were certified as having low care needs to investigate the relationship between the risk of frailty and two types of care services. The results showed that users of community-based adult care services had a 40% reduced risk of developing frailty compared to non-users. This suggests that utilizing appropriate support and services can prevent the progression of frailty.

Deepak Verma from Chulalongkorn University and his international team of researchers are exploring ways to enhance chitosan using techniques like adding photosensitizers, dendrimers, and chemical modifications. They also surveyed the use of chitosan nanoparticles for medical purposes, notably wound dressings.

Osaka Metropolitan University scientists have developed an AI model that accurately estimates a patient’s age, using chest radiographs of healthy individuals collected from multiple facilities. Furthermore, they found a positive relationship between differences in the AI-estimated and chronological ages and a variety of chronic diseases, such as hypertension, hyperuricemia, and chronic obstructive pulmonary disease. In the future, it is expected that AI biomarkers will be developed to predict life expectancy, estimate the severity of chronic diseases, and forecast surgery-related risks.

A research team co-led by City University of Hong Kong (CityU) and The University of Hong Kong (HKU) has recently made a significant advancement in spinal cord injury treatment by using genetically modified human neural stem cells (hNSCs). They found that specifically modulating a gene expression to a certain level in hNSCs can effectively promote reconstruction of damaged neural circuits and restore locomotor functions, offering great potential for new therapeutic opportunities for patients with spinal cord injury.

Fruit fly neural stem cells emerge as an exciting new model for unravelling the mysteries of dormancy, reactivation and neuronal regeneration. New studies unlock molecular pathways that could stimulate endogenous brain repair in neurodegenerative diseases and ageing.

A research led by scientists of Hong Kong Baptist University (HKBU) found that isoliquiritigenin (ISL), a flavonoid isolated from the Chinese herbal medicine licorice, can inhibit pancreatic cancer progression. It may also enhance the efficacy of conventional chemotherapeutic drugs in treating pancreatic cancer. It is the first time that a research group reported the anticancer potential of ISL in treating pancreatic cancer.

Osaka Metropolitan University scientists tested the antiobesity effects of Mallotus furetianus extract native to Hainan Island, China, using obesity model mice. As a result, body weight and adipose tissue weight of obesity model mice were significantly reduced by the intake of Mallotus furetianus extract. Fatty liver was suppressed and adipocyte size reduction in adipose tissue was observed. Further investigation into the mechanism revealed that fat synthesis is inhibited by suppressing the expression of several transcription factors involved in differentiation into adipocytes.

A research team from the Graduate School of Rehabilitation Science at Osaka Metropolitan University investigated the electrophysiological benefits of working in the presence of others from the perspectives of brain and autonomic nervous system activity. The researchers found that parasympathetic activity—which indicates relaxation—was significantly higher when two individuals were working separately than when one individual was working alone. This suggests that arranging the former condition in occupational therapy for individuals with high levels of tension or anxiety in clinical settings may potentially help alleviate these feelings.

The researchers from Osaka University showed how bone erosion caused by cholesteatoma occurs. This study showed that a subset of cells called osteoclastogenic fibroblasts expresses a protein, activin A, which causes the breakdown of the bones. Because of this discovery, novel medical treatments can be developed as first-line management for cholesteatomas.

Researchers from Osaka University found that patients with persistently high levels of urinary albumin excretion in the long term are at high risk of new-onset heart failure. Preventive treatment associated with the lowering of urinary albumin excretion levels in these patients could reduce the risk of later heart failure or mortality.

The Centre for Chinese Herbal Medicine Drug Development (CDD) of Hong Kong Baptist University (HKBU) has made significant progress in developing novel Chinese medicine for treating chronic constipation. With its success in the Investigational New Drug Application to the U.S. Food and Drug Administration (FDA), CDD has been authorised to conduct a phase I clinical trial of the new drug. This is the first time that a new botanical drug developed in Hong Kong was authorised to conduct a clinical trial in the US.

Lactate is a byproduct of exercise and metabolism, fueling our brain when oxygen is limited. More recently, scientists have become aware of the many roles it plays in developing our nervous system. Now, researchers from Tohoku University have unearthed the cellular mechanisms by which lactate helps our brains develop.

A joint research group at Osaka Metropolitan University conducted a survey on prevalence of obesity and factors associated with low obesity among 423 adolescents between the ages of 14 and 19 living in Harare, Zimbabwe. The results revealed that 15.8% were obese or overweight. The study also revealed that 27.1% of the participants had low obesity awareness, which was significantly related to parents/guardians' lack of formal education and insufficient knowledge about eating habits.

Researchers from Osaka University have developed a fluorescent sensor that may be useful for understanding how cells recognize themselves versus other cells when making connections in the brain. Specifically, their sensor can be used to visualize not only connections between cells, but also the disassociation of these interactions. Because neuronal self-connectivity has been implicated in brain disorders like epilepsy and autism, a better understanding of this process may result in improved therapies.

The physiological mechanisms underlying severe burns are not well understood. Researchers at Osaka University used mass spectrometry to identify key blood proteins associated with burn mortality. Ultimately, three proteins (HBA1, TTR, SERPINF2) were very highly correlated with morality rates. Further research into these proteins and their pathways may lead to better drugs to treat people with life-threatening burns.

Osaka Metropolitan University scientists have successfully developed a model that utilizes AI to accurately classify cardiac functions and valvular heart diseases from chest radiographs. The Area Under the Curve, or AUC, of the AI classification showed a high level of accuracy, exceeding 0.85 for almost all indicators and reaching 0.92 for detecting left ventricular ejection fraction—an important measure for monitoring cardiac function.

A group of researchers at Osaka University used a noninvasive method to evaluate Cerebrovascular Autoregulation (CVAR) in patients after out-of-hospital cardiac arrest. The mortality rate increased significantly with the duration of time that CVAR was undetectable. It has been suggested that CVAR, a function that is normally present in the normal state, may be impaired after cardiac resuscitation. However, the relationship between CVAR function and patient prognosis has been unclear. The research examined CVAR over time, using the moving Pearson correlation coefficient calculated from regional cerebral oxygen saturation and mean blood pressure data, and performed a survival analysis using the presence or absence of CVAR as a time-dependent covariate. The findings of this study may first be useful in predicting neuroprognosis after cardiac resumption and may help avoid early withdrawal of treatment in those who may recover. In addition, they suggest that treatment and management that maintains proper CVAR after cardiac resumption may improve patient prognosis, which may be applied to the management of post-cardiac arrest resuscitation based on cerebral circulation to optimize treatment for each individual patient.

Researchers from Osaka University have revealed the mechanism by which increased signaling through a pathway associated with a molecule called Wnt leads to the development of liver cancer. They identified a gene called GREB1 as a target of Wnt specifically in liver cancer. This gene alters the function of a protein called HNF4α, leading to the development of cancer. They also showed that treatment of mice with antisense oligonucleotides against GREB1 had significant anti-cancer effects.
