Cancer‑associated fibroblasts (CAFs) are predominate cells in tumor stroma and play a key role in tumor progression. Hepatocyte growth factor (HGF) is a cytokine mainly derived from fibroblasts. In the present study, we reported that HGF significantly promoted angiogenesis of human umbilical vein endothelial cells (HUVECs) and vasculogenic mimicry (VM) formation of gastric cancer cells, respectively, by increasing cell proliferation and migration. In addition, mosaic vessels formed by HUVECs and gastric cancer cells were also increased with treatment of recombinant human HGF and conditioned medium from CAFs...

BACKGROUND: Given the shortage of available organs for whole or partial liver transplantation, hepatocyte cell transplantation has long been considered a potential strategy to treat patients suffering from various liver diseases. Some of the earliest approaches that attempted to deliver hepatocytes via portal vein or spleen achieved little success due to poor engraftment. More recent efforts include transplantation of cell sheets or thin hepatocyte laden synthetic hydrogels. However, these implants must remain sufficiently thin to ensure that nutrients can diffuse into the implant...

OBJECTIVE: to report the first case of resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID) from living donor in a patient affected of irresectable colorectal liver metastases (i-CRLM) BACKGROUND:: A renaissance of liver transplantation (LT) for i-CRLM has been recently observed. The Norwegian SECA trial demonstrated a 5-year overall survival rate of approximately 60%, notwithstanding early tumor recurrence. The RAPID technique was recently introduced as alternative to whole deceased donor LT, but it is limited by poor availability of splittable organs and many organisational aspects...

A 58-year-old white male with a history of stroke and deep vein thrombosis presented with an interatrial intraseptal mass. Cardiac-computed tomography demonstrated a thin-walled, well-demarcated cyst in the inferior border of the fossa ovalis protruding into both atria. Removal of the interatrial intraseptal cyst was performed using a minimally invasive three-dimensional endoscopic periareolar approach.

: The introduction of new agents in multiple myeloma therapy has increased the overall response rate and improved clinical outcomes, but the increased risk of thrombotic complications impairs the quality of life of patient and the optimal thromboprophylaxis remains unknown. Increasing evidence has shown that statins can prevent venous thrombosis. Hence, we investigated the effects of simvastatin on multiple myeloma serum-related haemostatic imbalance in endothelial cells in vitro. The effects of simvastatin on procoagulant and anticoagulant protein expression were assessed on mixed multiple myeloma serum-treated human umbilical vein endothelial cells (HUVECs)...

Tetanus remains a significant burden in many low- and middle-income countries. The tetanus toxin acts within the central nervous system and intrathecal antitoxin administration may be beneficial, but there are safety concerns, especially in resource-limited settings. We performed a pilot study to assess the safety and feasibility of intrathecal human tetanus immunoglobulin in five adults with tetanus before the conduct of a large randomized controlled trial. Intrathecal injection via lumbar puncture was given to all patients within a median 140 (range 100-165) minutes of intensive care unit (ICU) admission...

BACKGROUND: Surgery remains the gold standard both for delimited hepatocellular carcinoma by selective anatomic liver segentectomy and for colorectal liver metastases by parenchymal sparing liver resection. Right anterior sector (RAS) (segments V-VIII; Couinaud) is the largest and most difficult sector to operate on. A better knowledge of its segmentation could prevent postoperative remnant liver ischemia and its impacts on patient's survival. METHODS: A literature search was conducted in PubMed for papers on anatomy and surgery of the right anterior sector...

BACKGROUND: Right hemihepatectomy or systematic resection of segment 7 or 8 involves partial resection of the paracaval portion of the caudate lobe. However, the boundary between the caudate lobe and segment 7 or 8 remains unclear. We examined the anatomical territory of the caudate lobe with special reference to the boundary between the paracaval portion and segment 7 or 8 for precise anatomical hepatectomies. METHODS: We enrolled 63 consecutive healthy donor candidates for living-donor liver transplantation from 2012 to 2014 in this study...

BACKGROUND: Non-malignant portal vein thrombosis (PVT) is common in patients with advanced liver disease. Anticoagulation (AC) increases the chances of recanalization and may improve liver function in patients with cirrhosis. AIM: We retrospectively assessed the course of non-malignant PVT in patients receiving AC. METHODS: Parameters related to hepatic injury (aspartate aminotransferase [AST]/alanine aminotransferase [ALT]), severity of disease (ascites) and synthesis function (albumin) as well as AC, rates of PVT regression/progression and AC-associated complications were documented...

BACKGROUND: Bile leakage after hepatectomy still causes relatively serious problems, and some types of bile leakage are intractable. CASE PRESENTATION: We report a case of postoperative isolated bile duct leakage managed successfully by combination therapy of percutaneous transhepatic portal vein embolization (PTPE) and bile duct ablation with ethanol. A 61-year-old man diagnosed with hepatocellular carcinoma underwent partial hepatectomy. On postoperative day 1, bile leakage was detected at the drainage tube...

Sympathetic premotor neurons of the paraventricular hypothalamus (PVN) play a role in hemodynamics adjustments during changes in body fluid homeostasis. However, PVN contribution to the tonic control of cardiac function remains to be systematically studied. In this study, we assessed whether GABAergic and adrenergic synapses, known for being active in the PVN, are involved in the control of cardiac function. Adult male Wistar rats (250-350 g; n = 27) were anesthetized with urethane (1.2-1.4 g/kg i.p.) and underwent catheterization of femoral artery to record blood pressure and heart rate...

Geminiviruses are major plant pathogens that threaten food security globally. They have a unique architecture built from two incomplete icosahedral particles, fused to form a geminate capsid. However, despite their importance to agricultural economies and fundamental biological interest, the details of how this is realized in 3D remain unknown. Here we report the structure of Ageratum yellow vein virus at 3.3 Å resolution, using single-particle cryo-electron microscopy, together with an atomic model that shows that the N-terminus of the single capsid protein (CP) adopts three different conformations essential for building the interface between geminate halves...

OBJECTIVE: When an autogenous vein is harvested and used for arterial bypass, it suffers physical and biologic injuries that may set in motion the cellular processes that lead to wall thickening, fibrosis, stenosis, and ultimately graft failure. Whereas the injurious effects of surgical preparation of the vein conduit have been extensively studied, little is known about the influence of the clinical environment of the donor leg from which the vein is obtained. METHODS: We studied the cellular responses of fresh saphenous vein samples obtained before implantation in 46 patients undergoing elective lower extremity bypass surgery...

The lower gluteal flap is an autologous microsurgical breast reconstruction procedure using the soft tissue of the region of the gluteal sulcus. The perineal extension increases the volume of the sample. The pedicle with one artery and two large veins extends up the ischial notch and can reach 8 to 12cm. The two operative positions, the relative shortness of the pedicle and the firm tissues transferred are balanced by the discretion of the sequelae of the donor site and the volume which is always enough even in the slim woman...

BACKGROUND: Arteriovenous fistula (AVF) may affect erythrocytes through many pathways (e.g., mechanical, inflammatory). However, these effects haven't been elucidated completely yet. OBJECTIVE: To follow-up the hemorheological and the hematological changes in the presence of artificial carotid-jugular fistula in rats. METHODS: Female Wistar rats were subjected to sham-operated group (SG, n = 6) and to fistula group (FG, n = 10). Under general anesthesia, the right carotid artery and jugular vein were isolated via a neck incision, and in the FG carotid-jugular fistula was performed by microsurgical techniques Hematological variables, red blood cell (RBC) deformability and membrane (mechanical) stability parameters were determined before operation and on the 1st and 6th postoperative weeks...

This article was requested by the Editor, Professor Harald Brevik after listening to a lecture I gave in a similar vein. Harald wanted the information in print and I have done this in a partly autobiographical form to explain how I came to work and learn from both the late John J. Bonica and the late Wilbert Fordyce. Both of these men have been important in different ways to our present pain world. John J. Bonica made many contributions not only in pain but in regional anesthesia and obstetrical anesthesia but not on the same level...
