Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Jedan pristup detekciji pokreta na slici scene / One approach to movement detection on image

Vojnotehnički Glasnik, 2006
U ovom radu opisan je jedan pristup koji se primenjuje u detekciji pokreta. Naime, koristi se obrada slike razlike formirane oduzimanjem slike pozadine od tekućeg frejma i oduzimanjem sukcesivnih frejmova.

Crossed-leg technique for digital subtraction angiography [PDF]

American Journal of Roentgenology, 1986
Intraarterial digital subtraction angiography (IADSA) is now well recognized as a preferred technique in the evaluation of peripheral vascular disease [1 -3]. In the study of the lower extremity the method is limited seriously by field size, motion of the part, and the air gap between both lower extremities. These limitations are substantially overcome

Beyond p‐values: Assessing clinical significance in acupuncture research

Advanced Chinese Medicine, EarlyView.
Abstract In acupuncture randomized controlled trials (RCTs), the proper interpretation of results requires a thorough understanding of key statistical concepts such as p‐value, effect size, and the minimal clinically important difference (MCID). This paper explores the relationships among these metrics and their implications for assessing the clinical ...

Comparison between subtraction and dynamic MRI in assessing treatment response following radiofrequency ablation in patients with hepatocellular carcinoma

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide, and if left untreated, one of the most lethal. Ablative therapies including radiofrequency ablation (RFA) play increasingly important role for patients with liver ...

Modelling Atherosclerotic Plaque Cap Mechanics: Microcalcifications Reduce Mechanical Properties in Mesenchymal Stromal Cell‐Based Model

Advanced Biology, EarlyView.
This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...

Near-surface defect detection in additively manufactured components using laser induced phased arrays with surface acoustic wave crosstalk suppression

Materials & Design, 2023
In-process inspection of the additive manufacturing process requires a technique that can provide reliable measurements given the extreme operating environments, the small size of the defects and the cyclic melting and heating of the material, caused by ...
