Virus adaptation to heparan sulfate comes with capsid stability tradeoff.

Because of high mutation rates, viruses constantly adapt to new environments. When propagated in cell lines, certain viruses acquire positively charged amino acids on their surface proteins, enabling them to utilize negatively charged heparan sulfate (HS) as an attachment receptor. In this study, we used enterovirus A71 (EV-A71) as the model and demonstrated that, unlike the parental MP4 variant, the cell-adapted strong HS-binder MP4-97R/167 G does not require acidification for uncoating and releases its genome in the neutral or weakly acidic environment of early endosomes.

Proton beam therapy in paediatric cancer: Anticipating the opening of the Australian Bragg Centre for Proton Therapy and Research.

Proton Beam Therapy (PBT) has the potential to improve paediatric cancer care by reducing radiation exposure and thus long-term toxicities. Ethical concerns and debates surrounding the treatment, such as eligibility and accessibility, are ongoing in Australia. The Australian Bragg Centre for Proton Therapy and Research (ABCPTR) (named after Sir William Henry Bragg who described the Bragg peak in his laboratory at the University of Adelaide in 1903) aims to increase access to PBT in Australasia and offer a patient-centred care approach.

Travelling overseas for proton beam therapy: A retrospective interview study.

Introduction: Travelling for cancer treatment comes with unique challenges, particularly for a young patient and his or her family. The aims of this study were to (1) gain an understanding of the experiences of families and patients who travelled overseas (OS) from Australia for proton beam therapy (PBT) and (2) identify the supportive care needs patients and their families require when living away from home, while having PBT.

Methods: This was a retrospective, qualitative study using semi-structured interviews, conducted with participants aged under 25 years and their families who travelled OS for PBT between 2017 and 2020.

A Malaysian consensus report on the diagnosis and treatment of infection.

is one of the most common chronic bacterial infections in humans and responsible for 90% of duodenal ulcers and 70-90% of gastric ulcers. Despite this, many misconceptions regarding the appropriate diagnostic method and treatment strategies still exist in the Malaysian clinical practice. Under the initiative of the steering committee, an expert panel consisting of nine key opinion leaders in the field of gastroenterology convened to develop a set of consensus statements that are relevant to the Malaysian healthcare practice.
