Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

FlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Influence of thoron on measurement results of radon exhalation rate

, 2002
Because of thoron exhalation, the measurement results of radon exhalation rate using a local still method is usually larger than the true value of radon flux rate of the monitored material surface.

Skin‐like ultra‐sensitive gas flow sensing based on ionically conductive organogels

InfoMat, EarlyView.
An elaborately designed gas flow sensor based on organogels was employed to precisely monitor trace gas flow disturbances. Leveraging a reversible ion‐mediated cooperative effect, the skin‐like gas flow sensor exhibited excellent sensing performance toward gas flow, featuring low operation voltage and high sensitivity.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Determination of Radon Exhalation Rates from Tiles (Marble, Granite and Ceramic) Using LR115 Type II Passive Technique

مجلة علوم ذي قار, 2019
Exhalation of 222Rn, ?-radioactive inert gas, is associated with the presence of 226Ra and it's ultimate precursor uranium in the earth crust. It is a useful quantity to compare the relative importance of different materials of tiles (marble, granite and

Effects of Single and Multiple Dose Tiotropium/Olodaterol in Chronic Obstructive Pulmonary Disease on Alveolar Gas Exchange Measured by Hyperpolarized 129Xe MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐acting muscarinic antagonists/long‐acting beta adrenoreceptor agonists lead to lung deflation and improved microvascular perfusion in hyperinflated chronic obstructive pulmonary disease (COPD), but with an unclear time course. Purpose To investigate the effect of inhalation of tiotropium/olodaterol (TIO/OLO) on MRI measures of ...

Open or closed: Experience of head and neck radiotherapy masks – A mixed‐methods study

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 74-84, March 2025.
Patients with head and neck cancer received radiotherapy alternately with an open and a closed mask. The closed mask was perceived as more confining and restrictive, but it was also considered to make it easier to quickly achieve the correct position, while the open mask was perceived as less stable, although it reduced the feeling of claustrophobia ...
