BACKGROUND: Intrahepatic cholangiocarcinoma with hepatic hilus involvement has been either classified as intrahepatic cholangiocarcinoma or hilar cholangiocarcinoma. The present study aimed to investigate the clinicopathologic characteristics and short- and long-term outcomes after curative resection for hilar type intrahepatic cholangiocarcinoma in comparison with peripheral intrahepatic cholangiocarcinoma and hilar cholangiocarcinoma. METHODS: A total of 912 patients with mass-forming peripheral intrahepatic cholangiocarcinoma, 101 patients with hilar type intrahepatic cholangiocarcinoma, and 159 patients with hilar cholangiocarcinoma undergoing curative resection from 2000 to 2015 were included from two multi-institutional databases...

Niemann-Pick type C disease (NP-C) is a fatal neurodegenerative disorder caused by a deficiency of NPC1 gene function, which leads to severe neuroinflammation such as astrogliosis. While reports demonstrating neuroinflammation are prevalent in NP-C, information about the onset and progression of cerebellar astrogliosis in this disorder is lacking. Using gene targeting, we generated vascular endothelial growth factor (VEGF) conditional null mutant mice. Deletion of VEGF in cerebellar Purkinje neurons (PNs) led to a significant increase of astrogliosis in the brain of NP-C mice in addition to the loss of PNs, suggesting PN-derived VEGF as an important factor in NP-C pathology...

RATIONALE: Solitary fibrous tumors are mesenchymal tumors presenting as fibroblastic neoplasms with prominent branching vascular patterns, which are often generated from the pleura. Most solitary fibrous tumors are benign; however, some can turn malignant. High-grade sarcomas from solitary fibrous tumors include multidirectional histopathological components. PATIENT CONCERNS: We describe our experience of a giant high-grade sarcoma with mixed components generated from a solitary fibrous tumor of the pleura in a 67-year-old female patient presenting with cough and left-sided chest pain...

Tubeimoside-1 (TBMS1), a triterpenoid saponin isolated from the tuber of Bolbostemma paniculatum (Maxim) Franquet, serves an universal suppressive role in multiple cancer types, including lung cancer. However, the mechanism involved in non‑small cell lung cancer (NSCLC) cells by which TBMS1 elicits its antitumor effects is not yet comple-tely understood. The present study indicated that 10 µmol/l TBMS1 significantly enhanced apoptosis and notably blocked the migration and invasion of NCI‑H1299 cells...

A 47-year-old Japanese man was referred to hospital after the detection of a liver tumor. Dynamic computed tomography and Gd-EOB-DTPA-enhanced magnetic resonance imaging were consistent with a diagnosis of hepatocellular carcinoma (HCC). No perfusion defect was observed in the post-vascular phase of contrast-enhanced ultrasound (CEUS). Histopathological staining of the tumor cells was positive for antibodies against HMB-45 and CD68, confirming the diagnosis of hepatic angiomyolipoma (HAML). These findings indicated the presence of macrophages in HAML...

The recreational use of cannabis has sharply increased in recent years in parallel with its legalization and decriminalization in several countries. Commonly, the traditional cannabis has been replaced by potent synthetic cannabinoids and cannabimimetics in various forms. Despite overwhelming public perception of the safety of these substances, an increasing number of serious cardiovascular adverse events have been reported in temporal relation to recreational cannabis use. These have included sudden cardiac death, vascular (coronary, cerebral and peripheral) events, arrhythmias and stress cardiomyopathy among others...

Vascular endothelial dysfunction plays an important role in the process of atherosclerosis up to the final stage of plaque rupture. Vascular endothelial dysfunction is reversible, and can be recovered by medications and life-style changes. Improvement in endothelial function may reduce cardiovascular events and improve long-term prognosis. A total of 50 patients with stable angina and dyslipidemia were enrolled, including patients who had not received prior treatment with statins and had serum LDL-C levels ≥ 100 mg/dL, and patients who had previously received statin treatment...

Mannans but not endo-β-mannanases are mainly found in the mucilage layer of two Brassicaceae seeds. Nonetheless, mannanase mobilization from inner to outer seed layers cannot be ruled out. The contribution of endo-β-mannanase (MAN) genes to the germination of the wild-type Sisymbrium officinale and cultivated Brassica rapa (Brassicaceae) species has been explored. In both species, mannans have been localized to the imbibed external seed coat layer (mucilage) by fluorescence immunolocalization and MAN enzymatic activity increases in seeds as imbibition progresses, reaching a peak before 100% germination is achieved...

The overall outcome of patients with hepatocellular carcinoma (HCC) is still very poor due to its high metastasis and recurrence rate. During metastasis, trans-endothelial migration (TEM) of HCC cells is a key step. Heparanase (HPSE) is an endo-beta-glucuronidase and exerts prometastatic properties for normal and tumor-derived cells. However, it is remains unclear that HPSE contributes to TEM of HCC cells. In this study, human umbilical vein endothelial cells-C (HUVEC-C) was used to simulate vascular endothelial cells (VECs), and the HCCLM3 cells with high HPSE expression were chosen and used for in vitro TEM assay and in vivo experiment...

The ventricles of the brain remain perhaps the largest anatomic structure in the human body without established primary purpose, even though their existence has been known at least since described by Aristotle. We hypothesize that the ventricles help match a stroke volume of arterial blood that arrives into the rigid cranium with an equivalent volume of ejected venous blood by spatially configuring cerebrospinal fluid (CSF) to act as a low viscosity relay medium for arteriovenous pulse wave (PW) phase coupling...

Arabidopsis thaliana VASCULAR-RELATED NAC-DOMAIN1 (VND1) to VND7 encode a group of NAC domain transcription factors that function as master regulators of xylem vessel element differentiation. These transcription factors activate the transcription of genes required for secondary cell wall formation and programmed cell death - key events in xylem vessel element differentiation. Because constitutive overexpression of VND6 and VND7 induces ectopic xylem vessel element differentiation, functional studies of VND proteins have largely focused on these two proteins...

In this report we present a case of re-stabilization of the proximal radius using vascularized free fibular graft combined with anconeus arthroplasty to stabilize the transplanted fibula in a patient with large loss of the proximal radius due to Ewing's sarcoma. A 20-year-old woman had Ewing's sarcoma in the proximal three-fourths of the radius. The resection of large part of the radius containing radial head were necessary for removal of the sarcoma. Reconstruction of the proximal radius was performed using vascularized free fibular graft and the transplanted fibula was stabilized by attaching the anconeus to the proximal edge of the fibula...

Dilated cardiomyopathy (DCM) is characterized by left ventricular dilation and cardiac fibrosis. Emerging evidence indicated that endothelial‑to‑mesenchymal transition (Endo‑MT) is a crucial event during organ fibrosis. This study was performed to clarify whether Endo‑MT contributed to the progression of cardiac fibrosis in DCM. Cardiac samples from patients with DCM and control were obtained. The presence of endothelial markers, cluster of differentiation (CD)31 and vascular endothelial (VE)‑cadherin, and mesenchymal markers, α smooth muscle actin (SMA) and fibroblast‑specific protein 1 (FSP1) was performed using immunohistochemistry...

9,10-Phenanthrenequinone (PQ), a major quinone component in diesel exhaust particles, is considered to provoke damage of respiratory and vascular cells through highly producing reactive oxygen species (ROS), but little is known about its pathophysiological role in neuronal cell damage. In this study, we found that incubation with 1,2-naphthoquinone, 1,4-naphthoquinone and PQ, major quinone components in diesel exhausts, provokes apoptosis of human neuroblastoma cell lines. SK-N-SH cell treatment with a lethal concentration of PQ facilitated ROS production within 6 h...

BACKGROUND: One goal of personalized medicine is leveraging the emerging tools of data science to guide medical decision-making. Achieving this using disparate data sources is most daunting for polygenic traits. To this end, we employed random forests (RFs) and neural networks (NNs) for predictive modeling of coronary artery calcium (CAC), which is an intermediate endo-phenotype of coronary artery disease (CAD). METHODS: Model inputs were derived from advanced cases in the ClinSeq®; discovery cohort (n=16) and the FHS replication cohort (n=36) from 89 (th) -99 (th) CAC score percentile range, and age-matched controls (ClinSeq®; n=16, FHS n=36) with no detectable CAC (all subjects were Caucasian males)...

Posterior reversible encephalopathy syndrome (PRES) is a clinical entity characterized by acute neurological symptoms such as severe headache, seizures, and visual disturbance, and by typical reversible lesion on brain magnetic resonance (MR) images. Since PRES is thought to be caused by vascular endothelial injury due to cytotoxic agents or acute systemic hypertension, the number of reports on PRES associated with angiogenesis inhibitors has been increasing. Although five cases that developed PRES due to pazopanib for renal cell carcinoma have already been reported, none of PRES due to pazopanib for soft-tissue sarcoma has been reported thus far...

Hypertension-related, calcium-regulated gene (HCaRG/COMMD5) is highly expressed in renal proximal tubules, where it contributes to the control of cell proliferation and differentiation. HCaRG accelerates tubular repair by facilitating re-differentiation of injured proximal tubular epithelial cells, thus improving mouse survival after acute kidney injury. Sustained hyper-proliferation and de-differentiation are important hallmarks of tumor progression. Here, we demonstrate that cancer cells overexpressing HCaRG maintain a more differentiated phenotype, while several of them undergo autophagic cell death...

The Epithelial Sodium Channel (ENaC) is a key player in renal sodium homeostasis. The expression of α β γ ENaC subunits has also been described in the endothelium and vascular smooth muscle, suggesting a role in vascular function. We recently demonstrated that endothelial ENaC is involved in aldosterone-modulated endothelial stiffness. Here we explore the functional role of the endothelial αENaC subunit in vascular function in vivo. Compared to littermates, mice with conditional αENaC subunit gene inactivation in the endothelium only (endo-αENaC Knock Out mice) had no difference in their physiological parameters such as systolic blood pressure or heart rate...
