Porphyrin‐Based Porous Materials for Antibacterial Applications

open access: yesAdvanced Science, EarlyView.
Porphyrin‐based porous materials have excellent photophysical properties and tunable structures for high‐efficiency antibacterial therapy. This review comprehensively discusses the structural design strategies and synthetic pathways of the four main types of porphyrin‐based porous materials, summarizes their cross‐domain antimicrobial applications, and

Targeted Mechanogenetics to Modulate Specific Deep Neural Circuits

open access: yesAdvanced Science, EarlyView.
This study introduces mechanogenetics, a nanobubble‐enhanced sonogenetic strategy for selective modulation of feeding‐related neural circuits in the mouse lateral hypothalamus. Mechanogenetic stimulation modulates feeding behavior through glutamatergic projections from the lateral hypothalamus to the ventral tegmental area, highlighting its potential ...

Ultrasound‐Activated Ce(IV)‐Integrated Biomimetic Nanoplatform for Oxygenation‐Reinforced Gas‐Sonodynamic Ferroptosis and cGAS–STING‐Driven Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
A Ce(IV)‐integrated biomimetic nanoplatform coordinates tumor oxygenation, ultrasound‐triggered carbon monoxide release, sonodynamic therapy, ferroptosis amplification, and cyclic GMP–AMP synthase (cGAS)–stimulator of interferon genes (STING) immune activation.

Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation

open access: yesAdvanced Science, EarlyView.
Hydrogel‐forming microneedle (HFMN)‐reservoir patches provide a modular route for controlled transdermal delivery of hydrophilic biomacromolecules. The platform integrates skin‐barrier penetration, sustainable biopolymers, scalable green manufacturing, hydration‐driven transport, model‐cargo validation, and translational quality requirements.

Blood gas measurements

Postgraduate Medicine, 1978
pH and blood gas measurements are used to detect and monitor ventilation, oxygenation, and acid-base disturbances. The blood sample must be drawn anaerobically and transported in ice water to the laboratory. Partial pressure of carbon dioxide in arterial blood (PaCO2) reflects alveolar ventilation; partial pressure of oxygen in arterial blood (PaO2 ...

BLOOD GAS MONITORING

Critical Care Clinics, 1996
Arterial blood gas (ABG) measurements are one of the most frequently requested laboratory examinations in critically ill patients. ABGs include measurement of pHa, PaCO2, PaO2, and oxyhemoglobin saturation. These measurements allow for assessment of the nature, progression, and severity of metabolic and respiratory disturbances.

Blood Gas Analyzers

Topics in Companion Animal Medicine, 2016
Acid-base and respiratory disturbances are common in sick and hospitalized veterinary patients; therefore, blood gas analyzers have become integral diagnostic and monitoring tools. This article will discuss uses of blood gas analyzers, types of samples that can be used, sample collection methods, potential sources of error, and potential alternatives ...

Blood gas measurement

Clinical Physics and Physiological Measurement, 1987
The adequacy of gas exchange in the lung is reflected in the partial pressures of the respiratory gases in the blood. The accurate measurement of these partial pressures is of fundamental importance in the diagnosis and treatment of cardiopulmonary disorders, and can determine the course of treatment for the severely ill patient.

Capillary blood gas as a substitute for arterial blood gas: a meta-analysis

British Journal of Hospital Medicine, 2014
Arterial blood gas sampling forms a vital part of bedside investigation but is invasive and physician dependent. This study aimed to determine whether capillary blood gas sampling could provide an accurate and less invasive substitute for the measurement of blood gases and pH.

Blood gas analysis

Veterinary Clinics of North America: Small Animal Practice, 2002
Evaluation of both arterial and central venous blood can be valuable in monitoring the critically ill veterinary patient. The traditional approach, which concentrates on arterial blood analysis only, may miss important aspects of oxygen delivery to tissues, especially in patients with poor perfusion.
