Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

Advanced Science, EarlyView.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Digital radiographic image enhancement for weld defect detection using smoothing and morphological transformations / Suhaila Abdul Halim, Arsmah Ibrahim and Yupiter Harangan Prasada Manurung

, 2012
Accurate inspection ofweldedmaterials is important in relation to achieve acceptable standards. Radiography, a non-destructive test method, is commonly used to evaluate the internal condition ofa material with respect to defect detection.

Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Evaluation of the image quality of an experimental lenticular film system for radiographic applications

, 1982
A lenticular film system designed to suppress image degrading crossover during dual screen radiographic exposure is proposed and evaluated. The lenticular screen consists of two sheets of crossed cylindrical lenslets each with a frequency of 25 lenslets ...

Decreasing Radiation Emission in Minimally Invasive Spine Surgery Using Ultra-Low-Radiation Imaging with Image Enhancement: A Prospective Cohort Study.

, 2019
BACKGROUND: Visualization of the anatomy in minimally invasive surgery (MIS) of the spine is limited and dependent on radiographic imaging, leading to increased radiation exposure to patients and surgical staff.

Accuracy of digital image processing in radiographic early caries detection

Majalah Kedokteran Gigi Indonesia
Tooth surface with early caries lesion can remineralize into sound tooth surface with early intervention. However, early caries lesion is difficult to detect and frequently goes unnoticed during clinical or radiographic examinations.

The Effect of Resistance Training and Ursolic Acid on the PI3K‐AKT‐mTOR Pathway in Aged Diabetic Rats: A Comparative Study

AGING MEDICINE, EarlyView.
Resistance training combined with ursolic acid supplementation restores anabolic signaling (PI3K/mTORC1) suppressed by diabetes, helping preserve muscle mass. This strategy may offer a potential therapeutic approach to combat muscle atrophy and support healthy aging in diabetic conditions.
