Viral diseases remain a major cause of death worldwide. Despite advances in vaccine and antiviral drug technology, each year over three million people die from a range of viral infections. Predominant viruses include human immunodeficiency virus, hepatitis viruses, and gastrointestinal and respiratory viruses. Now more than ever, robust, easily mobilised and cost-effective antiviral strategies are needed to combat both known and emerging disease threats. RNA interference and small interfering (si)RNAs were initially hailed as a "magic bullet", due to their ability to inhibit the synthesis of any protein via the degradation of its complementary messenger RNA sequence...

Context: Non-alcoholic fatty liver disease and elevated circulating branched-chain amino acids (BCAAs) are common characteristics of obesity and type 2 diabetes. In rodents, brain insulin signaling controls both hepatic triglyceride secretion and BCAA catabolism. Whether brain insulin signaling controls similar metabolic pathways in humans is unknown. Objective: Here we assessed if intranasal insulin, a method to preferentially deliver insulin to the central nervous system, is able to modulate hepatic lipid content and plasma BCAAs in humans...

Context: Accumulating evidence suggests that bisphenol A (BPA) exposure is associated with nonalcoholic fatty liver disease. Disruption of autophagy causes lipid accumulation in hepatocytes. Whether and how BPA regulates autophagy remains to be explored. Objective: We investigated the effect of BPA on autophagy in hepatocytes and examined the influence of BPA-regulated autophagy on hepatic lipid accumulation. Design: Male CD1 mice were treated with BPA for eight weeks, followed by histological and biochemical evaluation of liver lipids and autophagy...

Endoplasmic reticulum (ER) is the major site of protein folding and calcium storage. Beside the role of ER in protein homeostasis, it controls the cholesterol production and lipid-membrane biosynthesis as well as surviving and cell death signaling mechanisms in the cell. It is well-documented that elevated plasma cholesterol induces adverse effects in cardiovascular diseases (CVDs), liver disorders, such as non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatosis hepatitis (NASH), and metabolic diseases which are associated with oxidative and ER stress...

Fresh vegetables and their ready-to-eat (RTE) salads have become increasingly recognized as potential vehicles for foodborne diseases. The EU Reg. 1441/2007 establishes microbiological criteria for bacterial pathogens for products placed on the market during their shelf-life (i.e. Salmonella spp., Listeria monocytogenes) for pre-cut fruits and vegetables (RTE) whilst it does not address the problem of contamination by enteric viruses. In this study we investigated the contamination by hepatitis A virus (HAV), hepatitis E virus (HEV) and norovirus (NoV) in 911 ready-to-eat vegetable samples taken from products at retail in Apulia and in Lombardia...

OBJECTIVE: Animal models and studies in adults have demonstrated that copper restriction increases severity of liver injury in non-alcoholic fatty liver disease (NAFLD). This has not been studied in children. We aimed to determine if lower tissue copper is associated with increased NAFLD severity in children. METHODS: This was a retrospective study of pediatric patients who had a liver biopsy including a hepatic copper quantitation. The primary outcome compared hepatic copper concentration in NAFLD versus non-NAFLD...

Hyperammonemia is a metabolic condition characterized by elevated levels of ammonia and a common event in acute liver injury/failure and chronic liver disease. Even though hepatic ammonia levels are potential predictive factors of patient outcome, easy and inexpensive methods aiming at the detection of liver ammonia accumulation in the clinical setting remain unavailable. Thus, herein we have developed a morphological method, based on the utilization of Nessler´s reagent, to accurately and precisely detect the accumulation of ammonia in biological tissue...

BACKGROUND: Total hip arthroplasty (THA) costs are a source of great interest in the currently evolving health care market. The initiation of a bundled payment system has led to further research into costs drivers of this commonly performed procedure. One aspect that has not been well studied is the effect of comorbidities on the reimbursements of THA. The purpose of this study was to determine if common medical comorbidities affect these reimbursements. METHODS: A retrospective, level of evidence III study was performed using the PearlDiver supercomputer to identify patients who underwent primary THA between 2007 and 2015...

Neonatal acute liver failure is a rare, very severe disease with a high rate of mortality. It is clinically and etiologically different from acute liver failure seen in older children and adults. Coagulopathy with an international normalized ratio ≥ 3 is the critical parameter that defines it. The most common causes are fetal alloimmune hepatitis, previously called neonatal hemochromatosis, viral infections, metabolic disorders, and hemophagocytic lymphohistiocytosis. There is a group of treatable diseases that require a very early diagnosis for the prescription of an adequate treatment...

Hepatitis E virus (HEV) is responsible for more than 50% of acute viral hepatitis cases in endemic countries. Approximately 2 billion individuals live in hepatitis E-endemic areas and, therefore, are at risk of infection. According to World Health Organization, HEV causes about 20.1 million infections and 70 000 deaths every year. In developing countries with poor sanitation, this disease is transmitted through contaminated water and is associated with large outbreaks, affecting hundreds or thousands of people...

Hepatitis C virus (HCV) mediated chronic liver disease is a serious health problem around the world, and often causes fibrosis/cirrhosis, and hepatocellular carcinoma (HCC). The mechanism of liver disease progression during HCV infection is still unclear, although inflammation is believed to be an important player in disease pathogenesis. We previously reported that macrophages including Kupffer cells exposed to HCV induce proinflammatory cytokines. These secreted cytokines may activate hepatic stellate cells (HSCs) towards fibrosis...

OBJECTIVE: Sporadic inclusion body myositis (sIBM), an intractable progressive muscle disease, frequently occurs in older persons. sIBM pathogenesis may involve protein degradation dysfunction and immune abnormalities. Autoantibodies recognizing cytosolic 5'-nucleotidase 1A (cN1A) were found in plasma and serum from sIBM patients. Whether anti-cN1A autoantibodies play a pathogenic role in sIBM is controversial, however. This study investigated the pathogenic properties of anti-cN1A autoantibodies in sIBM pathogenesis...

Macrophages represent a key cellular component of the liver, and are essential for maintaining tissue homeostasis and ensuring rapid responses to hepatic injury. Our understanding of liver macrophages has been revolutionized by the delineation of heterogeneous subsets of these cells. Kupffer cells are a self-sustaining, liver-resident population of macrophages and can be distinguished from the monocyte-derived macrophages that rapidly accumulate in the injured liver. Specific environmental signals further determine the polarization and function of hepatic macrophages...

Glycogen storage disease type Ia (GSDIa, von Gierke disease) is the most common glycogen storage disorder. It is caused by the deficiency of glucose-6-phosphatase, an enzyme which catalyses the final step of gluconeogenesis and glycogenolysis. Clinically, GSDIa is characterized by fasting hypoglycaemia and hepatic glycogen and triglyceride overaccumulation. The latter leads to steatohepatitis, cirrhosis, and the formation of hepatic adenomas and carcinomas. Currently, little is known about the function of various organelles and their impact on metabolism in GSDIa...

Liver dysfunction occurs in approximately 50% of patients with systemic lupus erythematosus (SLE), and patients with SLE and elevated liver enzymes can present a complicated and difficult differential diagnosis. Lupus hepatitis and autoimmune hepatitis are 2 immunologic conditions involving the liver, which can have similar clinical, laboratory and systemic presentations, leading to difficulties in diagnosis. Physicians need to be aware of these 2 hepatic diseases as diagnosis and appropriate therapy need to occur early in the disease course to prevent progression to advanced liver disease...
