INTRODUCTION: Hepatic resection is performed for various benign and malignant liver tumors. Over the last several decades, there have been improvements in the surgical technique and postoperative care of patients undergoing liver surgery. Despite this, liver failure following an extended hepatic resection remains a critical potential postoperative complication. Patients with underlying parenchymal liver diseases are at particular risk of liver failure due to impaired liver regeneration with an associated mortality risk as high as 60 to 90%...

Hypogonadotropic hypogonadism (HH) is common and occurs prematurely in HIV-infected men. However, HH with very low testosterone has not been described. Three men with normal pubertal development and HIV1 diagnosis at the ages of 22, 34 and 35 years. All complained of decreased libido, anejaculation and erectile dysfunction thirteen years, six months and one year after HIV diagnosis, respectively. Two had depressive syndrome and two were treated with antiretroviral therapy. Laboratory tests revealed isolated HH in all...

Currently, intratumoral injection of an oncolytic adenovirus (Ad) is the conventional administration route in clinical trials. Nonetheless, the locally administered Ad disseminates to the surrounding nontarget tissues and has short biological activity due to immunogenicity of Ad, thus necessitating multiple injections to achieve a sufficient therapeutic index. In the present study, a tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-expressing oncolytic Ad (oAd-TRAIL) was encapsulated in a gelatin hydrogel (oAd-TRAIL/gel) to enhance and prolong antitumor efficacy of the virus after a single intratumoral injection...

Liver transplantation (LT) is the criterion standard of care in patients with end-stage liver disease and those with tumors of hepatic origin in the setting of liver dysfunction. Chronic immune rejection of the liver transplant can lead to bad prognosis for patients. Glucocorticoid-induced tumor necrosis factor receptor (GITR) play a key role in dominant immunologic self-tolerance maintained by CD25+/CD4+ regulatory T cells. Here, we investigated the DNA methylation variations of GITR and GITR ligand (GITRL) using pyrosequencing by analyzing blood DNA samples of patients after LT...

Vascular endothelial growth factor (VEGF) plays an important role in angiogenesis and is highly expressed in carcinoma, which make it an important target for tumor targeting therapy. Neuroblastoma is the main cause for cancer-related death in children. Like most solid tumors, it is also accompanied with the overexpression of VEGF. Doxorubicin Hydrochloride (DOX), a typical chemotherapeutic agent, exhibits efficient anticancer activities for various cancers. However, DOX, without targeting ability, usually causes severe damage to normal tissues...

Different edible oils such as lard and soybean oil have been reported to interact with the gut microbiota, affecting host lipid metabolism. However, whether bacteria derived from the environment influence host lipid metabolism remains unclear. This study aimed to clarify the roles of environmental bacteria in host lipid storage and distribution with various edible oils. Gnotobiotic C57BL/6JNarl mice were inoculated with Lysinibacillus xylanilyticus and Paenibacillus azoreducens and then fed either a normal diet (LabDiet 5010, control group) or a diet containing 60% lard (L-group) or soybean oil (S-group) for 18 months...

BACKGROUND: Orthotopic liver transplantation (OLT) is considered the standard for children with hepatoblastoma (HB) in whom complete surgical resection is not possible. However, OLT is not always available or feasible. OBJECTIVE: To describe the outcome of children with HB who were initially deemed unresectable and underwent complex hepatectomy with planned close margins, and ultimately avoided OLT. METHODS: Demographic data, surgical and pathologic details, and survival information were collected from children treated for HB between January 2010 to December 2015...

There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months...

Surgery-related morbidity has been identified as prognostic risk factor for tumor recurrence for several tumor types, but data regarding hepatocellular carcinoma (HCC) are limited and controversial. The aim of this study was to analyze the impact of surgical complications on the risk of HCC recurrence after hepatic resection (HR). A Retrospective study was conducted on a cohort of patients submitted to HR in a tertiary teaching hospital, between January 2006 and December 2015. 112 patients were submitted to HR during the study period...

BACKGROUND: The popularity of laparoscopic liver resection (LLR) is spreading, worldwide, because the intraoperative blood loss is less than for open hepatectomy and it is associated with a shorter hospitalization period [1-6]. During LLR, intraoperative hemostasis is difficult to achieve, unlike during laparotomy where bleeding can be stopped instantly [7-10]. Our LLR method for the treatment of hepatocellular carcinoma (HCC) includes maximal control of intraoperative bleeding using a monopolar soft-coagulation device...

The ketogenic diet (KD), a high-fat low-carbohydrate diet, has shown some efficacy in the treatment of certain types of tumors such as brain tumors and neuroblastoma. These tumors are characterized by the Warburg effect. Because renal cell carcinoma (RCC) presents similar energetic features as neuroblastoma, KD might also be effective in the treatment of RCC. To test this, we established xenografts with RCC 786-O cells in CD-1 nu/nu mice and then randomized them to a control diet or to KDs with different triglyceride contents...

Hepatitis C virus (HCV) is a leading cause of liver diseases including the development of hepatocellular carcinoma (HCC). Particularly, core protein has been involved in HCV-related liver pathologies. However, the impact of HCV core on signaling pathways supporting the genesis of HCC remains largely elusive. To decipher the host cell signaling pathways involved in the oncogenic potential of HCV core, a global quantitative phosphoproteomic approach was carried out. This study shed light on novel differentially phosphorylated proteins, in particular several components involved in translation...

The transcriptional nuclear factor kappa B (NF-κB)-coactivator B cell leukemia-3 (Bcl-3) is a molecular regulator of cell death and proliferation. Bcl-3 has been shown to be widely expressed in different cancer types including hepatocellular carcinoma (HCC). Its influence on hepatocarcinogenesis is still undetermined. To examine the role of Bcl-3 in hepatocarcinogenesis mice with hepatocyte-specific overexpression of Bcl-3 (Bcl-3(Hep)) were exposed to diethylnitrosamine (DEN) and phenobarbital (PB). Hepatic Bcl-3 overexpression attenuated DEN/PB-induced hepatocarcinogenesis...
