INTRODUCTION: In patients with a hypercoagulable state, such as patients with pulmonary embolism and/or Budd-Chiari syndrome, the complications from multiple gene mutations are more numerous than those from a single mutation. The authors present a woman with no major prior medical history who presented with pulmonary embolism and Budd-Chiari syndrome; this enigmatic co-occurrence has never been solely reported without underlying aetiology in a patient without prior medical conditions...

The response to glucagon and adrenaline in cancer cachexia is poorly known. The aim of this study was to investigate the response to glucagon, adrenergic agonists (α and β) and cyclic adenosine monophosphate (cAMP) on glycogenolysis, gluconeogenesis, and glycolysis in liver perfusion of Walker-256 tumor-bearing rats with advanced cachexia. Liver ATP content was also investigated. Rats without tumor (healthy) were used as controls. Agonists α (phenylephrine) and β (isoproterenol) adrenergic, instead of adrenaline, and cAMP, the second messenger of glucagon and isoproterenol, were used in an attempt to identify mechanisms involved in the responses...

Improved understanding of liver physiology and pathophysiology is urgently needed to assist the choice of new and upcoming therapeutic modalities for patients with liver diseases. In this review, we focus on functional PET of the liver: 1) Dynamic PET with 2-deoxy-2-[18 F]fluoro- D -galactose (18 F-FDGal) provides quantitative images of the hepatic metabolic clearance K met (mL blood/min/mL liver tissue) of regional and whole-liver hepatic metabolic function. Standard-uptake-value ( SUV ) from a static liver 18 F-FDGal PET/CT scan can replace K met and is currently used clinically...

INTRODUCTION: Laparoscopic hepatectomy is considered an acceptable treatment of choice in selected patients with primary hepatocellular carcinoma (HCC). Whether indocyanine green (ICG) immunofluorescence, a new technology, may improve surgery outcomes has yet to be tested. The aim of the present study was to investigate and compare the effect of ICG fluorescence imaging on the outcomes of pure laparoscopic hepatectomy and open hepatectomy for primary HCC with background cirrhosis. METHODS: From January 2015 to June 2016, 20 patients with HCC and liver cirrhosis underwent laparoscopic hepatectomy with ICG immunofluorescence...

Efforts have been made by the transplant community to expand the deceased donor pool in paediatric liver transplantation (LT). The growing experience on donation after circulatory death (DCD) for adult LT has encouraged its use also in children, albeit in selective cases, opening new perspectives for paediatric patients. Even though there has recently been a slight increase in the number of DCD livers transplanted in children, with satisfactory graft and patient outcomes, the use of DCD grafts in paediatric recipients is still controversial due to morbid outcomes associated with DCD grafts...

OBJECTIVE: To predict histological grade of hepatocellular carcinoma (HCC) in Wistar rats using intravoxel incoherent motion imaging (IVIM) with magnetic resonance imaging (MRI). METHODS: Liver lesions of HCC rat models induced by oral diethylnitrosamine (DEN) were scanned by IVIM to obtain apparent diffusion coefficient (ADC) and IVIM parameters,including true diffusion coefficient (D),pseudodiffusion coefficient (D*) and perfusion fraction (f). These HCC lesions were confirmed by Hematoxylin-Eosin (HE) stain and pathologically graded into low (grade Ⅰ+Ⅱ) and high (grade Ⅲ+Ⅳ) using the Edmondson-Steiner method...

Locoregionally advanced and unresectable disease can be seen in up to 10% of melanoma patients. Treatment options for these patients have been evolving most notably over the past few decades and have demonstrated efficacy through multiple intra-arterial as well as intralesional therapies. Isolated limb perfusions and isolated limb infusions have been utilized to treat locoregionally advanced melanoma of the extremity with overall response rates up to 90% in some reports. Intralesional therapies, for in transit metastatic melanoma, such as Bacille Calmette-Guerin, talimogene laherparepvec, and PV-10 (Rose Bengal) have all demonstrated efficacy in the treatment of unresectable cutaneous melanoma...

The systemic drug circulation represents a source of adverse effects during tumor targeting. We studied the binding efficacy of endothelium-specific antibodies after a very short contact with an antigen target, along with assessing the intravascular capture and targeting potential of these antibodies after locoregional injection. Fast-binding anti-CD146 (clone ME-9F1) and anti-CD31 (clone 390) antibodies were selected based on histological analysis of their binding activity. The efficacy of antibody capture by hepatic endothelium under different conditions was analyzed using an isolated liver perfusion model...

Adverse drug reactions (ADRs), particularly those that result in drug-induced liver injury (DILI) is a major cause of drug failure in clinical trials and drug withdrawals. Hepatotoxicity-mediated drug attrition occurs despite substantial investments of time and money in developing cellular assays, animal models and computational models to predict its occurrence in humans. Underperformance in predicting hepatotoxicity associated with drugs and drug candidates has been attributed to existing gaps in our understanding of the mechanisms involved in driving hepatic injury after these compounds perfuse and are metabolized by the liver...

Background: Acute heart failure (AHF) is associated with disturbances of the peripheral perfusion leading to the dysfunction of many organs. Consequently, an episode of AHF constitutes a "multiple organ failure" which may also affect the skeletal muscles. However, the abnormalities within skeletal muscles during AHF have not been investigated so far. The aim of this project is to comprehensively evaluate skeletal muscles (at a functional and tissue level) during AHF. Methods: The study will include ≥63 consecutive AHF patients who will be randomized into 2 groups: ≥42 with cardiac rehabilitation group versus ≥21 with standard pharmacotherapy alone...

BACKGROUND: Increased vascular permeability is a pathophysiological hallmark of sepsis and results in increased transcapillary leakage of plasma fluid, hypovolemia, and interstitial edema formation. 6% hydroxyethyl starch (HES 130/0.4) is commonly used to treat hypovolemia to maintain adequate organ perfusion and oxygen delivery. The present study was designed to investigate the effects of 6% HES 130/0.4 on glycocalyx integrity and vascular permeability in lipopolysaccharide (LPS)-induced pulmonary inflammation and systemic inflammation in mice...

BACKGROUND: Liver transplantation from donors after cardiac death (DCD) provides a solution to the donor shortage. However, DCD liver grafts are associated with a high incidence of primary graft nonfunction. We investigated the effectiveness of subnormothermic porcine liver perfusion, before transplantation from DCD, on graft viability. METHODS: Landrace pigs (25-30 kg) were randomly allocated to 3 groups (5 per group): heart-beating (HB) graft, transplanted after a 4-hour period of cold storage (CS); DCD graft, retrieved 20 minutes after apnea-induced cardiac arrest (respiratory withdrawal) and transplanted after a 4-hour period of CS; and subnormothermic ex vivo liver perfusion (SELP) graft, retrieved in the same manner as the DCD graft but perfused with a subnormothermic oxygenated Krebs-Henseleit buffer (21-25°C, 10-15 cm H2 O) for 30 minutes in a simplified dripping manner, without a machine perfusion system, after the 4-hour period of CS, and subsequently transplanted...

CLINICAL/METHODICAL ISSUE: Cross-sectional modalities or conventional ultrasound are not always able to sufficiently identify and characterize malignant liver lesions. STANDARD RADIOLOGICAL METHODS: The evaluation of malignant liver lesions in conventional ultrasound relies on echostructure, shape and borders, but often warrants additional contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) studies. METHODICAL INNOVATIONS: Contrast-enhanced ultrasound (CEUS) is a relatively safe imaging technique used for the detection and characterization of malignant liver lesions...

BACKGROUND: Schistosomiasis is an acute and chronic zoonotic parasitic disease caused by trematode worms. The host inflammatory response to schistosome eggs leads to perioval granulomata formation, mainly in the liver and intestine. This study investigated the potential antischistosomal and anti-inflammatory activity of both garlic extract and allicin on liver fibrotic markers in BALB/c mice with schistosomiasis (S. mansoni infection) compared with that of the commonly used drug, praziquantel (PZQ)...

Primary hepatocytes, as the gold standard cell type for in vitro models, lose their characteristic morphology and functions after few days. There is an urgent need to develop physiologically relevant models that recapitulate liver microenvironment to obtain mature hepatocyte from stem cells. We designed and fabricated a micro-bioreactor device mimicking the physiological shear stress and cell-cell interaction in liver sinusoid microenvironment. Induced pluripotent stem cells (iPSCs) were co-cultured with human umbilical vein endothelial cells (HUVECs) in the micro-bioreactor device with continuous perfusion of hepatic differentiation medium (100 μL/h)...
