Mycoplasma pneumoniae (M. pneumoniae) is a major cause of community acquired respiratory infections. And it also causes a number of extrapulmonary manifestations including cardiovascular, dermatological, musculoskeletal, and hematological systems. But, acute hepatitis without lung involvement is rare in adults. Here, we report a case of 32-year-old man who presented with fever, chilling, myalgia, and headache. Biochemical analysis showed severely impaired liver function and leukopenia. Laboratory tests and liver biopsy demonstrated a hepatocellular pattern of M...

Objective: To explore the surgical results and clinicopathological features of gastric cancer patients with liver metastases. Methods: The clinicopathological data and post-operative survival of 37 patients who underwent resection of liver metastasis from gastric cancer at our department from Dec. 2007 to Dec. 2014 were analyzed. Results: The 1-, 3-, and 5-year overall survival rates after resection were 91.4%, 57.9%, and 22.0%, respectively, with a median survival of 37 months. Univariate analysis revealed that lymph node metastasis, multiple hepatic metastases and no preoperative chemotherapy are unfavorable prognostic factors for overall survival...

Zebrafish are an attractive model organism for toxicology; however, an important consideration in translating between species is xenobiotic metabolism/bioactivation. CYP2E1 metabolizes small hydrophobic molecules, e.g. ethanol, cigarette smoke, and diesel exhaust components. CYP2E1 is thought to only be conserved in mammals, but recent reports identified homologous zebrafish cytochrome P450s. Herein, ex vivo biochemical measurements show that unlike mammals, zebrafish possess a low-affinity 4-nitrophenol hydroxylase (Km ∼0...

Human platelet lysates (PLs), which contain multiple neurotrophins, have been proposed for treating neurodegenerative disorders, including Parkinson's disease (PD). However, current PLs suspended in plasma have high protein content and contain fibrinogen/fibrin and, following activation, also proteolytic and thrombogenic enzymes. Upon brain administration, such PLs may saturate the cerebrospinal fluid and exert neurotoxicity. We assessed whether purified PLs, concentrated in neurotrophins, protected dopaminergic neurons in PD models...

Genome-wide association studies discovered interferon lambda (IFNL or IFN-λ) locus on chromosome 19 to be involved in clearance of chronic hepatitis C virus (HCV) infection in patients following interferon-α-ribavirin (IFN-RBV) therapy. Subsequent studies established a dinucleotide polymorphism rs368234815, as the prime causal variant behind this association. The ΔG allele of this variant gives rise to a new IFNL gene, IFNL4, coding for IFN-λ4 whose activity paradoxically associates with lesser viral clearance rates...

Hepatitis E virus (HEV) infection is a major cause of acute hepatitis but also provokes chronic infection in immunocompromised patients. Although the pathogenesis and treatment outcome involve complex interplay between the virus and host, the nature of adaptive responses of HEV to the host immune system remain obscure at best. In this study, we employed large-scale proteomic bioinformatics to profile characteristic mutations in human HEV isolates associated to ribavirin treatment failure, chronic hepatitis, hepatic failure or altered immunoreactivity...

The objective was to develop a method of HCV genome sequencing that allowed simultaneous genotyping and NS5A inhibitor resistance profiling. In order to validate the use of a unique RT-PCR for genotypes 1-5, 142 plasma samples from patients infected with HCV were analysed. The NS4B-NS5A partial region was successfully amplified and sequenced in all samples. In parallel, partial NS3 sequences were analyzed obtained for genotyping. Phylogenetic analysis showed concordance of genotypes and subtypes with a bootstrap >95% for each type cluster...

Oxidative stress resulting from endogenous and exogenous sources causes damage to cellular components, including genomic and mitochondrial DNA. Oxidative DNA damage is primarily repaired via the base excision repair pathway that is initiated by DNA glycosylases. 8-oxoguanine DNA glycosylase (OGG1) recognizes and cleaves oxidized and ring-fragmented purines, including 8-oxoguanine, the most commonly formed oxidative DNA lesion. Mice lacking the OGG1 gene product are prone to multiple features of the metabolic syndrome, including high-fat diet-induced obesity, hepatic steatosis, and insulin resistance...

BACKGROUND & AIMS: Recurrence of hepatocellular carcinoma (HCC) after hepatectomy is very high. A predictive marker of early recurrence (ER) capable of personalizing follow-up and developing a new target therapy would be beneficial. The overexpression of Filamin-A (FLNA), a cytoskeleton protein with scaffolding properties, has recently been associated with progression in tumors. The aim of this study was to test the expression of FLNA in a cohort of patients operated for HCC. METHODS: A retrospective cohort of patients who underwent hepatic resection at Humanitas Clinical and Research Center between January 2004 and December 2014 was analyzed...

It is a longstanding enigma how glycogen storage disease (GSD) type I patients retain a limited capacity for endogenous glucose production (EGP) despite the loss of glucose-6-phosphatase (G6Pase) activity. Insight into the source of residual EGP is of clinical importance given the risk of sudden death in these patients, but so far contradictory mechanisms have been proposed. We investigated G6Pase-independent EGP in hepatocytes isolated from a liver-specific GSD Ia mouse model (L-G6pc(-/-) mice), and performed real-time analysis of hepatic glucose fluxes and glycogen metabolism in L-G6pc(-/-) mice using state-of-the-art stable isotope methodologies...

Montmorillonite (MMT) is widely used as a mycotoxin adsorbent in animal feeds, but its safety remains unclear. This study was conducted to investigate the safety of MMT supplementation in diets fed to starter pigs. A total of 120 32-d-old piglets (initial weight, 8.0 ± 0.9 kg) were randomly allotted into dietary treatments with graded MMT levels (0 [FS 0], 0.5% [FS 0.5], 1.0% [FS 1.0], 2.5% [FS 2.5], and 5.0% [FS 5.0]) with 6 replicate pens per treatment and 4 pigs per pen. All diets were fed for 28 d. As the MMT level increased, ADG and G:F changed in a linear and quadratic manner, while ADFI was linearly decreased ( > 0...

Nutritional and genetic strategies are needed to enhance intramuscular fat (IMF) and MUFA content without altering carcass leanness. Dietary vitamin A restriction has been suggested to specifically promote IMF, whereas a polymorphism of the () gene has shown to specifically increase MUFA. The purpose of this study was to investigate the combined effects of provitamin A (PVA) carotenoid intake and genotype (>) on hepatic retinoid content and on the liver, muscle (LM and gluteus medius [GM]), and subcutaneous fat (SF) content and fatty acid composition...

Murine typhus occurs relatively commonly in southern Texas, as well as in California. We reviewed records of 90 adults and children in whom murine typhus was diagnosed during a 3-year period in 2 hospitals in southern Texas, USA. Most patients lacked notable comorbidities; all were immunocompetent. Initial signs and symptoms included fever (99%), malaise (82%), headache (77%), fatigue (70%), myalgias (68%), and rash (39%). Complications, often severe, in 28% of patients included bronchiolitis, pneumonia, meningitis, septic shock, cholecystitis, pancreatitis, myositis, and rhabdomyolysis; the last 3 are previously unreported in murine typhus...

Three-dimensional (3D) bio-printing technology is a promising new technology in the field of bio-artificial organ generation with regard to overcoming the limitations of organ supply. The cell source for bio-printing is very important. Here, we generated 3D hepatic scaffold with mouse induced hepatocyte-like cells (miHeps), and investigated whether their function was improved after transplantation in vivo. To generate miHeps, mouse embryonic fibroblasts were transformed with pMX retroviruses individually expressing hepatic transcription factors Hnf4a and Foxa3...

OBJECTIVE: Youth type 2 diabetes mellitus (T2DM) occurs decades earlier than adult T2DM and is characterized by high therapeutic failure rates and decreased response to insulin sensitizers suggesting a more severe disease process than in adults. To explain these observations, we hypothesized that insulin resistance is worse in obese youth than adults with impaired glucose tolerance (IGT), a state of high-risk for T2DM. As proof-of-concept, we compared insulin sensitivity between BMI-, sex-, and race-matched obese youth vs adults with IGT...

Although systemic responses have been described after traumatic brain injury (TBI), little is known regarding potential interactions between brain and peripheral organs after neuronal injury. In this sense, we decided to investigate whether peripheral oxidative/inflammatory response contributes to the neuronal dysfunction after TBI as well as prophylactic role of exercise training. Animals were submitted to fluid percussion injury (FPI) after 6 weeks of swimming training. Previous exercise training increased mRNA expression of X receptor alpha (LXR-α), ATP-binding cassette transporter (ABCA1), and decreased inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α) and interleukin (IL)-6 expression per se in liver...

Bilirubin detection plays a major role in healthcare. Its high concentration in human serum is lethal and must be determined accurately. Clinically, it is vital for assessing patients with deleterious health conditions such as jaundice or icterus, hepatitis, mental disorders, cerebral palsy and brain damage especially in the case of neonates. In evaluating the drawbacks regarding the conventional methodology of bilirubin detection, there is need for a superior analytical tool. Bilirubin oxidase (BOx)-based sensors have been designed for the ultrasensitive analysis of bilirubin and quality deliverance of treatment and this review highlights the different mechanisms of bilirubin detection using different modified electrodes...
