Viral infections have been the causes of global pandemics, including the ongoing coronavirus disease 2019, which prompted the investigation into the infection mechanisms to find treatment and aid the vaccine design. Betacoronaviruses use spike glycoprotein on their surface to bind to host receptors, aiding their host attachment and cell fusion. Protein-glycan interaction has been implicated in the viral entry mechanism of many viruses and has recently been shown in SARS-CoV-2. Here, we reviewed the current knowledge on protein-glycan interactions that facilitate SARS-CoV-2 host entry, with special interest in sialoglycans present on both the virions and host cell surfaces. We also analyze how such information provides opportunities and challenges in glyco-based inhibitors.

Microalgae offer a promising alternative for sustainable nutritional supplements and functional food ingredients and hold potential to meet the growing demand for nutritious and eco-friendly food alternatives. With the escalating impacts of global climate change and increasing human activities, microalgal production must be enhanced by reducing freshwater and land use and minimizing carbon emissions. The advent of 3D printing offers novel opportunities for optimizing microalgae production, though it faces challenges such as high production costs and scalability concerns.

Extreme environments such as hyperarid, hypersaline, hyperthermal environments, and the deep sea harbor diverse microbial communities, which are specially adapted to extreme conditions and are known as extremophiles. These extremophilic organisms have developed unique survival strategies, making them ideal models for studying microbial diversity, evolution, and adaptation to adversity. They also play critical roles in biogeochemical cycles.

Background: The prevalence of visual impairment among individuals living in long-term care (LTC) is substantial, yet eye care is often disregarded and inadequately addressed. This neglect contributes to a decline in quality of life for residents. Thus, understanding the challenges faced by stakeholders in providing eye care for residents might suggest opportunities to improve eye health outcomes.

Aim: This editorial presents state of the art developments in research and policy in the newly emerging field of climate and health and examines the gaps in research, the relevance of Nordic research in a global context, and the need to place the climate-health agenda in the policy space.
Methods: We use a set of articles from the Special Issue on 'Climate change and health in the Nordic countries' in this journal to understand current research in climate and health. We identify three emerging areas that characterize the current focus of research: modelling climate change-induced exposures; health cross-linkages of the climate health agenda and targeted communication.
The challenge of antimicrobial resistance in the Asia-Pacific: a pediatric perspective.
Curr Opin Pediatr
January 2025
Sydney Children's Hospital, Randwick, NSW.
Purpose Of Review: The densely populated Asia Pacific region is home to 600 million children, and suffers from a significant burden of morbidity and mortality due to infections associated with antimicrobial resistance (AMR). We aimed to identify the drivers, challenges and potential opportunities to alter the burden of AMR within the region.
Recent Findings: Despite the high AMR burden borne by the Asia Pacific region, there are limited (and geographically imbalanced) published data to delineate the contemporary epidemiology of serious multidrug-resistant bacterial infections in children.
