Olfactory perception can be studied in deep brain regions at high spatial resolutions with functional magnetic resonance imaging (fMRI), but this is complex and expensive. Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) are limited to cortical responses and lower spatial resolutions but are easier and cheaper to use. Unlike EEG, available fNIRS studies on olfaction are few, limited in scope, and contradictory.

Skeletal muscle tissue can regenerate after damage through the action of satellite cells, which proliferate as myoblasts when activated. Oxidative stress, marked by high rates of reactive oxygen species (e.g.

Targeting the peculiarities of tumor tissue microenvironment different from normal tissue, such as lower pH and overexpression of hydrogen peroxide is the key to effective treatment. In this study, acid-responsive Z-scheme heterojunctions polyglycolated MoS/CoFeO (MoS = molybdenum disulfide, CoFeO = cobalt ferrite) was synthesized using a two-step hydrothermal method, designated as MSCO-PEG, guided by dual modes of photoacoustic imagine (PAI) and nuclear magnetic imaging (MRI). MSCO-PEG (PEG = polyethylene glycol) responded to the acidic environment of tumor tissues and overexpression of hydrogen peroxide to turn on multimodal synergistic treatment of tumor cells under near-infrared-II (NIR-II) illumination.

To facilitate the implementation of controlled donation after circulatory death (cDCD) programs even in hospitals not equipped with a local Extracorporeal Membrane Oxygenation (ECMO) team (Spokes), some countries and Italian Regions have launched a local cDCD network with a ECMO mobile team who move from Hub hospitals to Spokes for normothermic regional perfusion (NRP) implantation in the setting of a cDCD pathway. While ECMO teams have been clearly defined by the Extracorporeal Life Support Organization, regarding composition, responsibilities and training programs, no clear, widely accepted indications are to date available for NRP teams. Although existing NRP mobile networks were developed due to the urgent need to increase the number of cDCDs, there is now the necessity for transplantation medicine to identify the peculiarities and responsibility of a NRP team for all those centers launching a cDCD pathway.

Over the past years, plant hypoxia research has produced a considerable number of new resources to monitor low oxygen responses in model species, mainly Arabidopsis thaliana. Climate change urges the development of effective genetic strategies aimed at improving plant resilience during flooding events. This need pushes forward the search for optimized tools that can reveal the actual oxygen available to plant cells, in different organs or under various conditions, and elucidate the mechanisms underlying plant hypoxic responses, complementing the existing transcriptomics, proteomics, and metabolic analysis methods.
