Microrobotic Doctors Roam Deep into Your Body for Treatments

A sci-fi adventure film from the 1960s, Fantastic Voyage, features a group of doctors shrinking into microscopic size and venturing into a patient’s brain to repair damages. A CUHK research team has recently brought this surreal fantasy to life by developing biohybrid soft microrobots, which navigates in tiny lumens for health inspections and medical treatments.

Vaccine Effectiveness against Seasonal Flu Predictable by Computer

Innovative algorithms developed by a CUHK team, using bioinformatics analysis of virus genome, can estimate vaccine effectiveness (VE) by quantifying the relationship between the genetic mismatch between flu vaccines and current virus strains. This real-time prediction method of VE early in flu season gives the government a heads-up in selecting effective vaccines and organising resources before mass vaccination.

Pioneering Genetic Test Gives Hope to Despairing Women

Frustration, disbelief, marital and mental stress can all come to women who have recurrent miscarriages but only half the couples could find out why it was happening to them. Now a new and more probing genome sequencing test – ChromoSeq is uncovering the causes, protecting the pathway to birth and rekindling hopes.

Health Secrets Behind the Window to the Soul

Eyes are the window to the soul, and so to our health. A research team from CUHK has developed Automatic Retinal Image Analysis technology to evaluate the risk of stroke and dementia. Recently, they have extended its application to assess the risk of autism in children by analysing their captured retinal images, hoping to reduce delayed diagnosis or even misdiagnosis.

Nasal Strip Gentle COVID-19 Test for All-Ages

Scared kids gagging on swabs probing into noses and throats or embarrassed old folk trying to heave up saliva has been the unhappy side of COVID-19 testing. Now, a nasal strip sampling for COVID-19 test that is gentle, fast, easy and accurate is on its way for all ages, equaling one of the standard test methods and out-performing the other.


Liver Disease Another Opening for COVID-19

Not only old age and other chronic conditions let in COVID-19. Those with liver damage are revealed as vulnerable and face eight times the risk of experiencing intensive care, mechanical ventilation, or death. CU Medicine researchers led an international hepatologists group in a statement pushing for better clinical management of COVID-19 liver disease sufferers.

Marathoning by Learning Muscle Synergies

Neuronal networks in the brain and spinal cord use a mechanism to adjust muscle commands for the way you run, depending on your body condition and experience. Research has found that muscle patterns – “muscle synergies” – are changed and merged across age and training groups, allowing runners to run longer with more energetic efficiency.

For Diabetes Sufferers – COVID-19 too?

Diabetes, already a major killer, could increase the risk of sufferers being infected by COVID-19 and severely. The alarm has been raised by researchers who have applied advanced statistical analysis to possible virus risks, and shed light on drug development for it. Diabetes patients need to watch their diets and be extra vigilant.


Finding the Guts to Fight off COVID-19

A university research team has found that lower levels of “good” bacteria and higher levels of “bad” bacteria in the gut of people with COVID-19 has made it harder for them to fight off the virus. The team has since developed a probiotic supplement based on this research to enhance the “good” bacteria thereby offering hope to boosting immunity against the virus in everyone who could be at risk.

Scratching Your Head, Biting Your Lip? You’re Coping with Stress

Previously unknown brain circuitry can generate repetitive behaviour that fends off harm from emotional stress. CUHK biomedical scientists find that responses like compulsive hand rubbing when anxious are coping mechanisms not to be repressed. That circuitry gone awry can also be a research lead into OCD and autism.

Maybe Not Too Late for Late Stage Cancer Sufferers

A new chapter is opening in cancer immunotherapy. A first-in-human clinical trial of CRISPR technology to treat late stage lung cancer has proved safe by a CUHK joint research. T-Cells of advanced condition patients have been extracted, gene edited and reinfused as potential fighters against cancer cells.


Stool Screening Helps to Uncover Asymptomatic Cases of COVID-19 Patients

Stool, found to be a “shed” for the coronavirus. According to the latest study, the coronavirus was found in faeces samples from 14 COVID-19 patients, regardless of the severity of their condition. 3 of them still had virus even though their respiratory secretions were cleared of the virus. Researchers suggest faeces test as an alternative screening.

Hong Kongers Scared Stiff of COVID-19 but still Get Together

98% of Hong Kongers feared catching the COVID-19 virus and practically all were abnormally anxious, while 90% were taking to strict mask wearing and hand washing, according to a survey in the outbreak’s early phase. But not to recommended “social distancing”. 90% of cases took 6 to 14 days between feeling ill and getting isolated.

Chinese Women with PCOS Show 4 Times Risk of Diabetes

It was known Chinese women with PCOS risk developing diabetes. Faculty of Medicine’s ten-year case-control study has now shown Chinese women have four times the risk and that onset will be earlier. Now affected women can be advised to be screened and have blood pressure monitored to reduce long term risks.
