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.

In a retrospective study drawing data from 973 participants between 2018 and 2020, researchers find that cases of metabolic dysfunction-associated fatty liver disease (MAFLD) increased from 22 pre-pandemic to 44 mid. Additionally, univariate and multivariate analysis of lifestyle habits reveal late-night meals pre-pandemic and increased alcohol intake mid-pandemic as independent lifestyle predictors of developing the disease.

Giants in History: Husband and wife team, Kimishige (3 December 1925 – 6 July 2018) and Teruko Ishizaka (28 September 1926 – 4 June 2019) discovered the antibody class Immunoglobulin E (IgE) that triggers allergic reactions.

Researchers have discovered in mice an additional use of globins as an intravenous drug that can delay liver fibrosis progression. Last year, the application of recombinant human cytoglobin (CYGB) as a protein therapeutic agent against liver damage and cirrhosis was published in Hepatology (Hepatology 2021,73:2527-2545) by Professor Norifumi Kawada’s research group. Here, they studied the antifibrotic properties of the globin family members hemoglobin (HB), myoglobin (MB), and neuroglobin (NGB) in comparison with CYGB. All globins demonstrated greater antioxidant capacity than glutathione in cell-free systems. Interestingly, all globins, except HB, could enter the cells and inhibit the collagen synthesis leading to a suppression of fibrosis development both in vitro and in vivo. The study was published in the journal Redox Biology.

A research group has revealed that amyloid-β (Aβ) detected in blood is secreted from peripheral tissues (pancreas, adipose tissue, skeletal muscle, liver, etc.) that are sensitive to glucose and insulin. Also, that Aβ secreted from peripheral tissues acts as a regulator on pancreatic β-cells to suppress insulin secretion. The results of this study indicate that blood Aβ levels fluctuate significantly with diet, and special care should be taken when using blood samples as a diagnostic marker for Alzheimer's disease, such as taking blood samples during fasting.
