Influence of neck tissue conductivities on the phrenic nerve activation threshold during non-invasive electrical stimulation

Current Directions in Biomedical Engineering
Phrenic nerve stimulation is used as an artificial ventilation method to reduce the adverse effects of mechanical ventilation, such as ventilator-induced diaphragmatic dysfunction. Detailed computational models and electromagnetic simulations are used to

Ranunculus calcareus and its role in lowland streams [PDF]

, 1979
Ranunculus calcareus , a species of water crowfoot which occurs in clear, nutrient-rich chalk streams, was studied. Seasonal changes in its biomass, its annual production and its fragmentation (leading to downstream movement of the plant) were ...

Artificial Respiration in Birds by Unidirectional Air Flow

, 1960
Depression of respiratory movements by anesthesia is a frequent cause of bird death during surgery; however, asphyxia so caused may often be prevented by artificial respiration.

Physical Intelligence in Small‐Scale Robots and Machines

Advanced Materials, EarlyView.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

Multimodal Measurement and Stimulation System to Investigate the Effects of Noninvasive Electrical Stimulation of the Phrenic Nerve

Current Directions in Biomedical Engineering
Mechanical ventilation, as performed daily in intensive care units, can lead to ventilator-induced diaphragmatic dysfunction. A reduction in diaphragmatic force generation can occur within the first 24 h.

Human neural stem cell-derived artificial organelles to improve oxidative phosphorylation

Nature Communications
Oxidative phosphorylation (OXPHOS) in the mitochondrial inner membrane is a therapeutic target in many diseases. Neural stem cells (NSCs) show progress in improving mitochondrial dysfunction in the central nervous system (CNS).

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.
