Background: Disturbances in calcium and phosphorus homeostasis resulting from chronic kidney disease (CKD) may lead to atherosclerotic changes in blood vessels, potentially altering bone marrow perfusion. Our study aimed to investigate vertebral bone marrow perfusion using dynamic contrast-enhanced (DCE) MRI with a pharmacokinetic model. We also measured possible changes in water and fat content and bony trabeculae using T2* quantification, MR spectroscopy (MRS), and microcomputed tomography (μCT).

In a super-aging society, the increase in the elderly population is closely tied to a rise in infectious diseases due to factors such as weakened immune systems and decreased vaccine efficacy in older adults. Various opportunistic pathogens commonly encountered in everyday life can cause infections and diseases when an individual's immune defence is weakened due to aging. These factors underscore the importance of preventive measures against pathogenic infections and the aging of immune systems in the elderly.

Parasites have their strongest impact on fitness when host defences deplete resources needed for other critical life-history stages, such as development, breeding or migration. Among birds, one greatly neglected stage that could be altered by parasites is post-juvenile moult (PJM), through which yearling juvenile birds replace their fast-generated, low-quality juvenile feathers with adult-like feathers after leaving the nest. The earlier the birds complete PJM, the earlier they will be prepared to withstand forthcoming challenges, such as adverse winter conditions or migration.

MedComm (2020)
February 2025
Rapid advances in vaccine technology are becoming increasingly important in tackling global health crises caused by respiratory virus infections. While traditional vaccines, primarily administered by intramuscular injection, have proven effective, they often fail to provide the broad upper respiratory tract mucosal immunity, which is urgently needed for first-line control of respiratory viral infections. Furthermore, traditional intramuscular vaccines may not adequately address the immune escape of emerging virus variants.

Clinically, multimodal therapies are adopted worldwide for the management of cancer, which continues to be a leading cause of death. In recent years, immunotherapy has firmly established itself as a new paradigm in cancer care that activates the body's immune defense to cope with cancer. Immunotherapy has resulted in significant breakthroughs in the treatment of stubborn tumors, dramatically improving the clinical outcome of cancer patients.
