Could Hong Kong scientists fight age-related muscle loss with help of HIV drug?
Researchers from the
Chinese University of Hong Kong (CUHK) said on Wednesday that they had tested the HIV drug, known as Maraviroc, on 18-month-old mice suffering from sarcopenia, a progressive age-related condition that causes loss of muscle mass and strength.
The study found that mice saw significant improvements in their muscle mass, grip strength and running endurance after receiving high doses of the drug for three months.
Dr Michael Ong Tim-yun, a clinical assistant professor at CUHK's orthopaedics and traumatology department, said one in seven people aged 65 and above in Hong Kong suffered from sarcopenia, with the amount rising to 50 per cent of residents over the age of 80.
'This figure might be an underestimation as many patients who actually have symptoms of sarcopenia are not aware of it,' Ong said.
Ong, who is part of the research team, explained that sarcopenia could be diagnosed by measuring a person's muscle mass, handgrip strength and walking speed.
The only treatments currently available are exercise and protein supplementation, with no drugs used to treat the condition at this point.

Hong Kong records first case of Japanese encephalitis in 6 years
Hong Kong has recorded its first case of Japanese encephalitis in six years after a 49-year-old woman was diagnosed with the potentially fatal mosquito-borne disease upon returning from the Philippines. The Centre for Health Protection said on Wednesday that the imported case involved a foreign woman who was in a stable condition. She had travelled to the Philippines between July 21 and August 4, including visiting rural areas. 'Since the patient stayed in the Philippines during the incubation period, the centre considered that she was infected during travel, and the case was classified as an imported one,' it said. The centre said the woman suffered from a fever, headache and vomiting from August 10 and had sought medical help from the accident and emergency department of Prince of Wales Hospital in Sha Tin two days later. The Japanese encephalitis virus is principally transmitted by the bites of infected mosquitoes. Photo: Shutterstock. She was hospitalised last Thursday when she visited the hospital for a second time due to persistent symptoms.

Mathematician Zhang Yitang says he left US for China due to political climate
Mathematician Zhang Yitang, who joined Sun Yat-sen University in Guangzhou from California in June, has called the wave of Chinese researchers exiting the US a 'positive trend'. Zhang, known for his prime number research, told Phoenix TV, a partially state-owned broadcaster, in a programme aired on Monday that he had been thinking about returning to the mainland 'in light of recent international political issues that have strained China-US relations'. 'Many Chinese scholars and professors in the US have already returned, and many others are still considering it,' Zhang said. 'I think this is a positive trend.' 'My field is not greatly affected, but for researchers in computers, chips or anything related to the military industry, they need to be especially careful,' he warned. 'The US is very strict about these areas now.' Zhang (left) receives his letter of appointment as a full-time faculty member at Sun Yat-sen University's Institute of Advanced Studies Hong Kong on June 27, 2025.
