Novel intranasal vaccine targeting SARS-CoV-2 receptor binding domain to mucosal microfold cells and adjuvanted with TLR3 agonist Riboxxim™ elicits strong antibody and T-cell responses in mice.

SARS-CoV-2 continues to circulate in the human population necessitating regular booster immunization for its long-term control. Ideally, vaccines should ideally not only protect against symptomatic disease, but also prevent transmission via asymptomatic shedding and cover existing and future variants of the virus. This may ultimately only be possible through induction of potent and long-lasting immune responses in the nasopharyngeal tract, the initial entry site of SARS-CoV-2.

Rotation Invariant Clustering of 3D Cell Nuclei Shapes.

Cellular imaging with confocal fluorescence laser microscopy gave rise to many new insights into the cellular machinery. One interesting observation suggests that morphology of cell nucleus plays a key role for neutrophilic function, which is an essential part of the innate immune system of most mammals. Due to the increasing availability of high resolution 3D images coming from the microscope, machine learning becomes a promising tool for automatically discovering underlying hidden structures.

Transforming concepts in patient safety: a progress report.

In 2009, the National Patient Safety Foundation's Lucian Leape Institute (LLI) published a paper identifying five areas of healthcare that require system-level attention and action to advance patient safety.The authors argued that to truly transform the safety of healthcare, there was a need to address medical education reform; care integration; restoring joy and meaning in work and ensuring the safety of the healthcare workforce; consumer engagement in healthcare and transparency across the continuum of care. In the ensuing years, the LLI convened a series of expert roundtables to address each concept, look at obstacles to implementation, assess potential for improvement, identify potential implementation partners and issue recommendations for action.

Proteomic comparison defines novel markers to characterize heterogeneous populations of extracellular vesicle subtypes.

Extracellular vesicles (EVs) have become the focus of rising interest because of their numerous functions in physiology and pathology. Cells release heterogeneous vesicles of different sizes and intracellular origins, including small EVs formed inside endosomal compartments (i.e.
