Recurrent Post-Traumatic Adrenal Bleeding after Transcatheter Arterial Embolization: A Case Report.

Adrenal gland trauma is uncommon and is diagnosed at an increasing frequency using CT scans. However, owing to the rarity of this injury and its diverse clinical presentations and prognoses, there is no consensus on its management. In this case report, a 73-year-old male patient experienced recurrent bleeding in the right adrenal gland due to an in-car traffic accident, which was treated with repeated transcatheter arterial embolization.

Inhibition of Dickkopf-1 enhances the anti-tumor efficacy of sorafenib via inhibition of the PI3K/Akt and Wnt/β-catenin pathways in hepatocellular carcinoma.

Background: Sorafenib improves the overall survival in patients with advanced hepatocellular carcinoma (HCC). Dickkopf-1 (DKK1) is commonly overexpressed in HCC. In this study, we investigated whether the inhibition of DKK1 enhances the anti-tumor efficacy of sorafenib in HCC.

Neutrophil-to-lymphocyte ratio is an independent predictor for neurological disability in patients with idiopathic transverse myelitis.

Introduction: The neutrophil-to-lymphocyte ratio (NLR) has been found to be useful in the prognostication of immune-mediated neurological disorders because it roughly reflects the systemic innate immune response compared to the adaptive immune response. However, studies on the validity of NLR in demyelinating disorders of the central nervous system have shown conflicting results. Therefore, we aimed to investigate NLR in the idiopathic transverse myelitis (ITM) cohort.

An Artificial Intelligence Model for Predicting Trauma Mortality Among Emergency Department Patients in South Korea: Retrospective Cohort Study.

Background: Within the trauma system, the emergency department (ED) is the hospital's first contact and is vital for allocating medical resources. However, there is generally limited information about patients that die in the ED.

Objective: The aim of this study was to develop an artificial intelligence (AI) model to predict trauma mortality and analyze pertinent mortality factors for all patients visiting the ED.

[Clinical Role of Interventional Radiology in Abdominal Solid Organ Trauma].

Interventional management is commonly used for traumatic injuries to the abdominal solid organs. The American Association for the Surgery of Trauma (AAST) and the World Society of Emergency Surgery (WSES) recently published guidelines for the management and treatment of liver, spleen, and kidney injuries, emphasizing the importance of interventions. Here, we discuss the characteristics of each organ and the procedure method for each organ that interventional radiologists need to know when treating trauma patients.

Co-administration of ursodeoxycholic acid with rosuvastatin/ezetimibe in a non-alcoholic fatty liver disease model.

Background: Ursodeoxycholic acid (UDCA), statins, and ezetimibe (EZE) have demonstrated beneficial effects against non-alcoholic fatty liver disease (NAFLD). We investigated the efficacy of the combination of UDCA and the mix of rosuvastatin (RSV)/EZE in the treatment of NAFLD.

Methods: NAFLD mouse models were developed by injecting thioacetamide, fasting, and high-carbohydrate refeeding, high-fat diet, and choline-deficient L-amino acid-defined high-fat diet (CDAHFD).

Successful endovascular embolization for traumatic subcutaneous abdominal wall hematoma via the superficial inferior epigastric artery: a case report.

Abdominal wall hematoma (AWH) after blunt trauma is common, and most cases can be treated conservatively. More invasive treatment is required in patients with traumatic AWH if active bleeding is identified or there is no response to medical treatment. Herein, we report a case of endovascular embolization for traumatic subcutaneous AWH.

A micellized bone morphogenetic protein-7 prodrug ameliorates liver fibrosis by suppressing transforming growth factor- signaling.

Bone morphogenetic protein-7 (BMP-7) antagonizes transforming growth factor-β (TGF-β), which is critically involved in liver fibrogenesis. Here, we designed a micelle formulation consisting of a protein transduction domain (PTD) fused BMP-7 polypeptide (mPTD-BMP-7) to enhance endocytic delivery, and investigated its ability to ameliorate liver fibrosis. The mPTD-BMP-7 formulation was efficiently delivered into cells via endocytosis, where it inhibited TGF-β mediated epithelial-mesenchymal transition.

Pharmacological Inhibition of Sonic Hedgehog Signaling Suppresses Tumor Development in a Murine Model of Intrahepatic Cholangiocarcinoma.

Cholangiocarcinoma (CCC) is the second most primary liver cancer with an aggressive biological behavior, and its incidence increases steadily. An aberrant up-regulation of the sonic hedgehog signaling pathway has been reported in a variety of hepatic diseases including hepatic inflammation, fibrosis, as well as cancer. In this study, we determined the effect of a sonic hedgehog inhibitor, vismodegib, on the development of CCC.

Dickkopf-1 promotes angiogenesis by upregulating VEGF receptor 2-mediated mTOR/p70S6K signaling in hepatocellular carcinoma.

The expression of Dickkopf-1 (DKK1), a negative regulator of the Wnt/β-catenin signaling pathway, is upregulated in hepatocellular carcinoma (HCC). Here, we investigated the tumorigenic and angiogenic potential of DKK1 in HCC. Stable cell lines were established using the clustered regularly interspaced short palindromic repeats (CRISPR)-associated nuclease 9 (CRISPR/Cas9)-based DKK1 knock-out system in Hep3B cells and the tetracycline-based DKK1 inducible system in Huh7 cells.

Efficacy and Safety of Percutaneous Transhepatic Cholangioscopy with the Spyglass DS Direct Visualization System in Patients with Surgically Altered Anatomy: A Pilot Study.

Background/aims: : Percutaneous transhepatic cholangioscopy (PTCS) is used for the diagnosis and treatment of biliary diseases in patients with failed endoscopic retrograde cholangiopancreatography, particularly those with surgically altered anatomy. However, few studies are available on the clinical use of Spyglass DS direct visualization system (SpyDS)-assisted PTCS. This study aimed to assess the efficacy and safety of SpyDS-assisted PTCS in patients with surgically altered anatomy, particularly those with a Roux-en-Y reconstruction.

Genetically Engineered Mouse Models for Liver Cancer.

Liver cancer is the fourth leading cause of cancer-related death globally, accounting for approximately 800,000 deaths annually. Hepatocellular carcinoma (HCC) is the most common type of liver cancer, comprising approximately 80% of cases. Murine models of HCC, such as chemically-induced models, xenograft models, and genetically engineered mouse (GEM) models, are valuable tools to reproduce human HCC biopathology and biochemistry.

Early recanalization after intravenous administration of recombinant tissue plasminogen activator as assessed by pre- and post-thrombolytic angiography in acute ischemic stroke patients.

Background And Purpose: Recanalization rates after the intravenous (IV) recombinant tissue plasminogen activator (rt-PA) treatment have been poorly studied in acute stroke.

Methods: CT angiography was performed before IV rt-PA in all patients and digital subtraction angiography was undertaken for intra-arterial thrombolysis in cases of no improvement after rt-PA infusion.

Results: Forty-five patients were treated with IV rt-PA.

Proteasomal ATPase-associated factor 1 negatively regulates proteasome activity by interacting with proteasomal ATPases.

The 26S proteasome, composed of the 20S core and the 19S regulatory complex, plays a central role in ubiquitin-dependent proteolysis by catalyzing degradation of polyubiquitinated proteins. In a search for proteins involved in regulation of the proteasome, we affinity purified the 19S regulatory complex from HeLa cells and identified a novel protein of 43 kDa in size as an associated protein. Immunoprecipitation analyses suggested that this protein specifically interacted with the proteasomal ATPases.
