Neuroscience 2021 Apr 7. Epub 2021 Apr 7.

Department of Otolaryngology-Head and Neck Surgery, The First Affiliated Hospital of USTC, Hefei, 230001, China. Electronic address:

To investigate the role of the exchange protein directly activated by cAMP (Epac) signaling pathway in inner ear hair cell damage and apoptosis after noise exposure, we analyzed the expression level of Epac1 in a rat model of noise-induced hearing loss (NIHL), based on rat exposure to a 4-kHz and 106-dB sound pressure level (SPL) for 8 h. Loss of outer hair cells (OHCs), mitochondrial lesions, and hearing loss were examined after treatment with the Epac agonist, 8-CPT, or the Epac inhibitor, ESI-09. The effects of 8-CPT and ESI-09 on cell proliferation and apoptosis were examined by CCK-8 assays, holographic microscopy imaging, and Annexin-V FITC/PI staining in HEI-OC1 cells. Read More

Use of Indocyanine Green During Repair of a Superior Mesenteric Artery Aneurysm.

Ann Vasc Surg 2021 Apr 7. Epub 2021 Apr 7.

Division of Vascular and Endovascular Surgery, University of Louisville, Louisville, Kentucky, USA. Electronic address:

Superior mesenteric artery (SMA) aneurysms are rare and associated with a high risk of rupture, with resultant significant morbidity and mortality. During open operative repair of a superior mesenteric artery aneurysm, perfusion of the involved small bowel must be evaluated when determining need for and/or extent of vascular reconstruction. We present a case of a 51-year-old woman who underwent open repair of a non-ruptured superior mesenteric artery aneurysm with ligation and excision, in whom no revascularization was determined to be needed and the involved small bowel was able to be preserved, with intraoperative evaluation of perfusion using indocyanine green (ICG) fluorescence imaging, as an adjunct to more traditional methods of perfusion assessment.

Upregulation of ZHX2 predicts poor prognosis and is correlated with immune infiltration in gastric cancer.

FEBS Open Bio 2021 Apr 10. Epub 2021 Apr 10.

Department of Gastrointestinal Surgery, Laboratory Research Center, The First Affiliated Hospital of Chongqing Medical University, Chongqing, 400016, PR China.

The transcriptional repressor Zinc-finger and homeoboxes 2 (ZHX2) is reported to regulate tumor progression in several human cancers, but little is known about its role in gastric cancer (GC). In this study, we examined the expression of ZHX2 and its relationship with clinicopathological characteristics and prognosis of GC patients, and examined the effect of ZHX2 overexpression in GC cell lines. We used UALCAN and Tumor Immune Estimation Resource (TIMER) to examine ZHX2 mRNA expression, and used Kaplan-Meier plotter to determine whether ZHX2 expression was related to GC prognosis. Read More
