It has been shown that the pyrolysis of cellulose at low pressure (1.5 Torr) can be described by a three reaction model. In this model, it is assumed an "initiation reaction" leads to formation "active cellulose" which subsequently decomposes two competitive first-order reactions, one yielding volatiles and other char gaseous fraction. Over temperature range 259–341°C, rate constants these ki (for → cellulose"), kv "volatiles"), kc + fraction) are given = 1.7 × 1021e− (58,000/RT) min −1, 1.9...

MicroRNA (miRNA) plays an important role in the pathology of various diseases, including infection and cancer. Using real-time polymerase chain reaction, we measured expression 188 miRNAs liver tissues obtained from 12 patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) 14 C (HCV)-related HCC, background normal nine patients. Global gene same was analyzed via complementary DNA microarray to examine whether differentially expressed could regulate their target genes....

Abstract Vacuum pyrolysis of cellulose within the temperature range 300–500°C provides a tar fraction containing mainly levoglucosan and glucose condensation products. It was found that proceeds at much faster rate higher temperatures without detrimental effect on yields. At 400°C reaction essentially complete 3 min yielding contained 39% and, upon mild acid hydrolysis, gave 49% D‐glucose. The yields could be further improved by washing or treatment cellulosic substrates with acids. Cotton...

The replication and infectivity of the lipotropic hepatitis C virus (HCV) are regulated by cellular lipid status. Among differentially expressed microRNAs (miRNAs), we found that miR-27a was preferentially in HCV-infected liver over B (HBV)-infected liver. Gene expression profiling Huh-7.5 cells showed regulates metabolism targeting synthetic transcription factor RXRα transporter ATP-binding cassette subfamily A member 1. In addition, repressed many metabolism-related genes, including FASN,...

Many tumor-associated antigens (TAAs) recognized by cytotoxic T cells (CTLs) have been identified during the last two decades and some of them used in clinical trials. However, there are very few field immunotherapy for hepatocellular carcinoma (HCC) because not comparative data regarding CTL responses to various TAAs. In present study, using 27 peptides derived from 14 different TAAs, we performed analysis TAA-specific T-cell 31 HCC patients select useful examined factors that affect immune...

Cirrhosis is a chronic liver disease that impairs hepatic function and causes advanced fibrosis. Mesenchymal stem cells have gained recent popularity as regenerative therapy since they possess immunomodulatory functions. We found injected adipose tissue-derived (ADSCs) reside in the liver. Injection of ADSCs also restores albumin expression parenchymal ameliorates fibrosis nonalcoholic steatohepatitis model cirrhosis mice.

Background Pancreatic ductular adenocarcinoma (PDAC) is among the most dreadful of malignancies, in part due to lack efficacious chemotherapy. Immune checkpoint inhibitors, including anti-programmed cell death 1 (anti-PD-1) antibodies, are novel promising forms systemic immunotherapy. In current study, we assessed whether gemcitabine (GEM) combined with anti-PD-1 antibody treatment was as immunochemotherapy for advanced PDAC using a murine model liver metastasis.
