Effect of dipeptidyl peptidase‐4 inhibitor on the progression of coronary artery disease evaluated by computed tomography in patients receiving insulin therapy for type 2 diabetes mellitus DPP‐4抑制剂对接受胰岛素治疗的2型糖尿病患者冠状动脉疾病进展的影响

Journal of Diabetes, Volume 15, Issue 11, Page 944-954, November 2023., 2023
Highlights Preclinical data showed that dipeptidyl peptidase‐4 inhibitors (DPP‐4is) may prevent insulin‐induced atherosclerosis. In patients treated with insulin for type 2 diabetes who underwent ≥2 serial coronary computed tomography angiographies(CCTA), a new obstructive coronary artery disease (OCAD) was less developed on the follow‐up CCTA in those

Early incisor lesions and Equine Odontoclastic Tooth Resorption and Hypercementosis: Reliability of radiographic findings

Equine Veterinary Journal, Volume 55, Issue 2, Page 261-269, March 2023., 2023
Summary Background In clinical practice, early diagnosis of Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) and other resorptive incisor diseases is difficult to achieve. The radiographic appearance of subtle pathological changes has not been described in detail and might be confused with age‐related changes.

Brachycephaly in French bulldogs and pugs is associated with narrow ear canals

Veterinary Dermatology, Volume 33, Issue 3, Page 214-e60, June 2022., 2022
Background Brachycephalic dog breeds have multiple skull malformations which may lead to anatomical changes in the external auditory canal. It is our frequent observation that in the otoscopic examination of the external ear in these breeds we are unable to visualise the tympanic membrane as a consequence of extreme narrowing of the proximal ear canal.

Surface‐Enhanced Raman Scattering‐Based Multimodal Medical Imaging in Cancer Diagnosis and Therapy Monitoring

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Prospective external validation of ADNEX and RMI for estimating risk of malignancy in adnexal masses in general gynecological settings: Danish multicenter study

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 256-269, August 2026.
ABSTRACT Objectives The primary aims of this study were to validate externally the diagnostic performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model for distinguishing between malignant and benign adnexal masses, when used by non‐expert ultrasound examiners in general gynecological settings with a low prevalence of ovarian ...

Dual Checkpoint Inhibition with Ipilimumab plus Nivolumab After Progression on Sequential PD‐1/PDL‐1 Inhibitors Pembrolizumab and Atezolizumab in a Patient with Lynch Syndrome, Metastatic Colon, and Localized Urothelial Cancer

The Oncologist, Volume 24, Issue 11, Page 1416-1419, November 2019., 2019
Abstract Immune checkpoint blockade (ICB) is an approved therapy for advanced metastatic mismatch repair (MMR)‐deficient cancer regardless of tissue of origin. Although therapy is effective initially, recurrence rates are significant, and long‐term outcomes remain poor for most patients.
