Modular photoswitch cpLOV2 developed for optogenetic engineering

Researchers designed cpLOV2 using circular permutation to simplify optogenetic device design. The new photoswitch maintained structural integrity and function, providing more choices for optogenetic application developments. It was successfully used to gate ORAI1 Ca2+ channel and control cell activities in a mouse model.

Study reveals huge pressures on anaesthesia and critical care workforce and hospitals during winter wave of COVID-19 pandemic, and devastating drop in surgical activity

During the winter wave of COVID-19, anaesthetic and critical care staff in the UK faced immense pressure due to a surge in newly admitted infected patients. Surgery rates plummeted by one quarter compared to previous years, with many hospitals expanding ICUs to accommodate the influx.

Icing muscle injuries may delay recovery

A study using a mouse model of eccentric contraction revealed that icing injured muscles delays muscle regeneration. The phenomenon is linked to pro-inflammatory macrophages' ability to infiltrate damaged cells, delaying the healing process.

Study shows optimized multi-scale structure and chemical gradients in exoskeletons of mantis shrimps

Researchers discovered a four-layered exoskeleton with distinctive micro-structure and chemical characteristics that restrict crack propagation and maximize strain energy release during deformation. Bio-mimetic structures fabricated via 3D printing demonstrated improved toughness and strength, guiding high-performance composites fabric...

Maintaining self-control -- The careful balance of the immune system

A new study by University of Tsukuba researchers reveals how two receptors, DNAM-1 and TIGIT, maintain the necessary balance between immune activation and suppression to prevent autoimmune diseases. The findings suggest that an imbalance in this mechanism may contribute to autoimmunity, providing potential targets for treatment.

One-year results from the FUTURE-II trial

A randomized trial comparing a new, thin-strut bioresorbable scaffold with a metallic stent showed non-inferiority of the bioresorbable scaffold in terms of late lumen loss and covered struts. The trial's results may revitalize the concept of bioresorbable scaffolds.

Novel method of labeling DNA bases for sequencing

Researchers developed a novel method for labeling DNA bases using electrochemical detection and redox labels. This approach allows for the identification of individual nucleotides in a single strand of DNA, enabling faster and more affordable DNA sequencing and diagnostic applications.

New model helps predict heart attacks in high-risk patients

Researchers have developed a new approach to analysing the forces at play behind diseased heart vessels, which could help cardiologists predict heart attacks in patients. The study used optical coherence tomography images to generate patient-specific reconstructions of coronary plaques and analyse stress concentrations.

Epigenetics study draws link between hatchery conditions and steelhead trout fitness

A Washington State University study links alterations in hatchery-raised steelhead trout's epigenetic programming to reduced fertility and abnormal health. The research suggests that faster growth practices and environmental factors can lead to epigenetic changes passed down through generations, impacting wild fish populations.
