Hepatocellular cancer is the most common type of primary liver cancer. Cirrhosis is the main risk factor that generates this malady. It has been proven that caloric restriction protocols and restricted feeding schedules are protective in experimental carcinogenic models. We tested the influence of a time-caloric restriction protocol (2 h of food access during the daytime for 18 weeks) in an experimental model of cirrhosis-hepatocarcinoma produced by weekly administration of diethylnitrosamine. Our results indicate that time-caloric restriction reduced hepatomegaly and prevented the increase in blood leukocytes promoted by diethylnitrosamine...

INTRODUCTION: Leptospirosis remains a significant health problem in tropical regions including Latin America, where its presentation is 100 times higher than that observed in other regions of the world. Mortality reaches 10% in severe cases. Its diagnosis is challenging because clinical manifestations during the initial phase are non-specific and because of limited availability of diagnostic tests. OBJECTIVE: To describe the demographic and clinical characteristics and the outcomes in hospitalized patients with leptospirosis...

Congenital pure erythroid leukemia is exceedingly rare and poses a diagnostic challenge. We report an atypical case of congenital pure erythroid leukemia that did not express typical erythroid markers. The patient presented with a high white blood cell count with blastic cells at birth. Although flow cytometric analyses of peripheral blood and bone marrow showed a large CD45-negative cell population, we did not identify any evidence of monoclonality. While the circulating blasts decreased with only supportive care, hepatomegaly with multiple nodules was accompanied by liver failure, disseminated intravascular coagulation, and development of hemophagocytic lymphohistiocytosis...

Cardiac amyloidosis may occur in any type of systemic amyloidosis. The clinical picture is often characterized by restrictive cardiomyopathy. We report the case of a 41-year-old female patient admitted to the Department of Cardiology with clinical signs of right heart failure: congested jugular veins, hepatomegaly, peripheral edema, ascites associated with atrial fibrillation, low values of arterial blood pressure and oliguria. Echocardiographic findings were helpful for the diagnosis of cardiac amyloidosis: enlarged atrial cavities, normal size ventricles, thickened ventricular septum and posterior left ventricle wall with normal left ventricular ejection fraction, mitral and tricuspid regurgitation...

A 3-year-old, spayed female, Domestic Shorthair cat presented with anorexia, lethargy, vomiting, probable hemoabdomen, and multiple masses on the right lateral liver lobe. Clinicopathologic and imaging abnormalities included anemia, azotemia, icterus, and hepatomegaly with hypoechoic masses. On cytologic evaluation of a fine-needle aspiration of a liver mass there was abundant extracellular pink- to purple-colored material between hepatocytes. The amorphous material was stained with direct fast scarlet (DFS), and green birefringent areas were observed under polarized light, confirming the presence of amyloid...

Both Pten and Nras are downstream mediators of receptor tyrosine kinase activation that plays important roles in controlling cell survival and proliferation. Here, we investigated whether and how Pten loss cross-talks with Nras activation in driving liver cancer development in mice. Somatic disruption of hepatic Pten and overexpression of Nras were achieved in out-bred immunocompetent CD-1 mice through a hydrodynamic delivery of plasmids carrying Sleeping Beauty transposon-based integration of Nras and the CRISPR/Cas9-mediated Pten knock-out system...

Lysosomal acid lipase deficiency (LAL-D) is still a little recognized genetic disease with significant morbidity and mortality in children and adults. This document provides guidance on when to suspect LAL-D and how to diagnose it. It is recommended to add lysosomal acid lipase deficiency to the List of differential diagnoses of sepsis, oncological diseases, storage diseases, persistent diarrhea, chronic malnutrition, and hemophagocytic lymphohistiocytosis. It should also be considered in young patients with dyslipidemia and atherosclerosis as well as diseases associated with fatty liver and/or hepatomegaly...

BACKGROUND & AIMS: Low aerobic capacity increases risk for NAFLD and liver-related disease mortality, but mechanisms mediating these effects remain unknown. We recently reported that rats bred for low aerobic capacity (low capacity runner (LCR)) displayed susceptibility to high-fat diet-induced steatosis in association with reduced hepatic mitochondrial fatty acid oxidation (FAO) and respiratory capacity compared to high aerobic capacity (high capacity runners (HCR)) rats. Here we tested the impact of aerobic capacity on susceptibility for progressive liver disease following a 16 week 'western diet' high in fat (45% kcal), cholesterol (1% w w(-1) ), and sucrose (15% kcal)...

The advances of our understanding in the Hippo signaling as a key regulatory pathway of proliferation and apoptosis have provided mechanical insights for controlling organ size and tumorigenicity. Recently, much attention was given to the regulation of LATS1/2 (large tumor suppressor) kinases that phosphorylate YAP/TAZ, a transcriptional co-activator in the Hippo pathway, and control the level and nuclear localization of YAP/TAZ. In our recent work, we showed that deubiquitinase YOD1 stabilizes ITCH and facilitates ITCH-mediated LATS1/2 ubiquitination and degradation, which results in increased YAP/TAZ level...

BACKGROUND: Castleman disease is a rare lymphoproliferative disorder presenting with localized or disseminated lymphadenopathy and systemic manifestations. It can be categorized in numerous ways, such as unicentric versus multicentric, histopathological variants (hyaline-vascular, plasma cell, and mixed), or subtypes based on causative viral infections (human immunodeficiency virus, human herpesvirus-8, or Kaposi sarcoma herpesvirus). Presentation ranges from asymptomatic to symptoms involving multiple organs...

CASE SUMMARY: A 17-year-old female neutered domestic shorthair cat presented for several days of reduced faecal volume and a rectal prolapse. Physical examination revealed a 2 cm rectal prolapse, hepatomegaly and a low body condition score of 3/9. Haematology and biochemistry revealed a mild non-regenerative anaemia (haematocrit 24.5%; reference interval [RI] 30.3-52.3%), a mild mature neutrophilia (16.21 × 10(9)/l; RI 1.48-10.29 × 10(9)/l) and a mild increase in alanine aminotransferase activity (222 IU/l; RI 12-130 IU/l)...

Mucopolysaccharidosis type II (MPS II, Hunter syndrome) is a rare X-linked recessive lysosomal disorder caused by defective Iduronate-2-sulfatase (IDS) resulting in accumulation of heparan sulfate and dermatan sulfate glycosaminoglycans (GAGs). Enzyme replacement is the only FDA-approved therapy available for MPS II, but it is expensive and does not improve neurologic outcomes in MPS II patients. We conducted this study to evaluate the effectiveness of adeno-associated virus (AAV) vector encoding human IDS delivered intracerebroventricularly in a murine model of MPS II...

OBJECTIVE: The aim of this study was to determine variables predictive of abnormal comprehensive metabolic panel (CMP) results in pediatric emergency department (PED) patients and the potential cost savings of a basic metabolic panel (BMP) versus a CMP. METHODS: This is a retrospective cross-sectional descriptive study of children (<18 y) at an urban academic PED (annual census, 22,000). Clinical data included 12 clinical variables: right upper quadrant pain, overdose, emesis, liver disorder, malignancy, heart disease, bleeding disorder, jaundice, right upper quadrant tenderness, hepatomegaly, ascites/peripheral edema and shock, and the liver function test (LFT) results not in a BMP (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total protein, and albumin)...

Wnt proteins modulate cell proliferation and differentiation and the self-renewal of stem cells by inducing β-catenin-dependent signalling through the Wnt receptor frizzled (FZD) and the co-receptors LRP5 and LRP6 to regulate cell fate decisions and the growth and repair of several tissues. The 19 mammalian Wnt proteins are cross-reactive with the 10 FZD receptors, and this has complicated the attribution of distinct biological functions to specific FZD and Wnt subtype interactions. Furthermore, Wnt proteins are modified post-translationally by palmitoylation, which is essential for their secretion, function and interaction with FZD receptors...

Zoonotic infections are increasingly becoming public health menaces and are usually transmitted to humans due to unsuitable environmental conditions. One of them is hepatic capillariasis, caused by the parasite Capillaria hepatica, primarily a disease of rodents, with hepatic manifestations in humans. Although its prevalence is very low, it can cause significant morbidity and mortality, with cases reported from all over the world. The main infective form for humans is the embryonated egg of the parasite, which hatch in the intestine and ultimately colonize the liver...
