Ammonia Dynamics in the Human Body: Insights in Biomedical Sensing Technologies

Advanced Sensor Research, EarlyView.
Ammonia (NH3) is a significant biomarker in diagnostics, affecting the respiratory system, stomach, liver, kidneys, bladder, and gastrointestinal tract. NH3 detection, using sensors, has the potential to improve medical diagnosis. This review examines recent advancements in NH3 sensing technologies and explores future research directions, including ...

Carbogen inhalation during Non-Convulsive Status Epilepticus: A quantitative analysis of EEG recordings [PDF]

arXiv, 2019
Objective: To quantify the effect of inhaled 5% carbon-dioxide/95% oxygen on EEG recordings from patients in non-convulsive status epilepticus (NCSE). Methods: Five children of mixed aetiology in NCSE were given high flow of inhaled carbogen (5% carbon dioxide/95% oxygen) using a face mask for maximum 120s. EEG was recorded concurrently in all patients.

Opportunities in Therapeutic mRNA Stabilization: Sequence, Structure, Adjuvants and Vectors

Advanced Therapeutics, EarlyView.
Current mRNA lipid nanoparticles rely on cold storage, which increases the cost and reduces access to the vaccines. As mRNA expands to other clinical opportunities, better methods to stabilize the medicines during shipping, storage, and delivery are needed.

ROS‐Driven Nanoventilator for MRSA‐Induced Acute Lung Injury Treatment via In Situ Oxygen Supply, Anti‐Inflammation and Immunomodulation

Advanced Science, EarlyView.
A ROS‐driven in situ oxygen supply nanoventilator based on enzyme nanocapsule can convert ROS into O2 through enzyme cascade reaction between SOD and CAT to relieve lung hypoxia, and kill MRSA by releasing vancomycin, which effectively reduces HIF‐1α expression and balances pro‐inflammatory/anti‐inflammatory macrophages ratio, thereby reducing the ...

Functional Polarization of Liver Macrophages by Glyco Gold Nanoparticles

Advanced Science, EarlyView.
Macrophages play a critical role in several pathophysiological diseases by being involved in the activation of adaptive and innate immune responses. The repolarization of macrophages using gold nanoparticles functionalized with glycans for a more selective targeting toward a restorative phenotype leads to an amelioration of the events.

Titration of oxygen therapy in critically ill emergency department patients: a feasibility study

BMC Emergency Medicine, 2018
Background Liberal use of oxygen in an emergency situation is common. Today, most health care professionals do not adjust the amount of oxygen given when a saturation of 100% or a PaO2 which exceeds the normal range is reached- which may result in ...

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

Advanced Science, EarlyView.
Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...
