Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

Head &Neck, Volume 48, Issue 6, Page 1620-1629, June 2026.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.

A Study on the Characteristics of Sonazoid Contrast‐Enhanced Ultrasound in the Transitional Phase for Common Focal Liver Lesions and Its Value in Differential Diagnosis

Journal of Ultrasound in Medicine, Volume 45, Issue 6, Page 1235-1245, June 2026.
Objective To investigate the value of transitional phase characteristics on Sonazoid contrast‐enhanced ultrasound (S‐CEUS) in the differential diagnosis of common focal liver lesions (FLLs). Materials and Methods This prospective multicenter study enrolled 122 participants with FLLs from 8 medical centers between December 2023 and March 2025. The study

Nerve Ultrasound Detects Peripheral Nerve Enlargement in Cerebrotendinous Xanthomatosis

Muscle &Nerve, Volume 73, Issue 6, Page 1082-1088, June 2026.
ABSTRACT Introduction/Aims Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by variants in the CYP27A1 gene, resulting in cholestanol accumulation in various tissues, including peripheral nerves. Polyneuropathy is common but often under‐recognized in CTX.

Estrogen Deprivation During Primate (Papio anubis) Pregnancy: Impact on Systemic Microvascular Flow and Cardiovascular Development and Function After Birth in Offspring

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Suppressing estradiol (E2) during baboon pregnancy lowers offspring skeletal muscle capillary density, vital for insulin‐mediated glucose uptake, and induces insulin resistance. We examined whether E2 deprivation also impairs microvascular flow and cardiac function.

Single‐Cell Sequencing Reveals That CCL2+ Adipose‐Derived Stem Cells Promote Diabetic Wound Healing Through the CCL2‐ACKR1 Signaling Axis

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
scRNA‐seq of human adipose and diabetic wounds revealed a CCL2+ ADSC subpopulation with high stemness and ECM‐enriched pathways. These cells serve as a signaling hub via TGFB1‐TGFBR1, IL34‐CSF1R, and CCL2‐ACKR1. Their exosomes (CCL2‐Exos), carrying CCL2, TGFB1, and IL34, accelerate diabetic wound healing in mice by promoting angiogenesis, collagen ...

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, Volume 13, Issue 26, 8 May 2026.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

The Usefulness of Ultrasound Colour-Doppler Twinkling Artefact for Detecting Urolithiasis Compared with Low Dose Nonenhanced Computerized Tomography

Ultrasound in Medicine and Biology, 2012
This prospective study evaluates the usefulness of the twinkling artefact (TA) seen on colour-Doppler ultrasound (US) in diagnosing urolithiasis. US and standard computed tomography (CT) were performed blinded on 105 patients. B-mode US and colour-Doppler used separately and in combination showed 55% sensitivity and 99% specificity (positive predictive
