Research ArticleOpen accessEvery word in the titleEvidences of Apoptosis in Hepatitis C Virus-Infected Hepatocytes and Peripheral Blood Monocuclear Cells in the Absence of Liver InjuryViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Understanding the mechanism of Hepatitis C Virus (HCV) pathogenesis is an important part of HCV research. In this study, the presence of apoptosis in HCV-infected liver and Peripheral Blood Mononuclear Cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA was investigated. The samples obtained from 21 patients were studied by in situ Hybridization (ISH), Immunofluorescence, TUNEL … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,975 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvidences of Hepatitis C Virus Replication in Hepatocytes and Peripheral Blood Monocuclear Cells from Patients Negative for Viral RNA in SerumViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.In this study, we examined the expression of hepatitis C virus (HCV) components in hepatocytes and peripheral blood mononuclear cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA. The samples obtained from 25 randomly selected patients (13 of 25 patients showed no histological evidences of chronic hepatitis and had normal serum ALAT and GGTP levels) were … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,164 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,907 accessesView PDFCite
Review ArticleOpen accessIn the keywordsSpecific Markers for Hepatic Progenitor CellsMsy Rulan Adnindya, Indriyani, Ahmad Azmi Nasution, Isabella Kurnia LiemOne of mammalian organs that has remarkable ability to regenerate, liver, regenerates through the proliferation of hepatocytes or proliferation and differentiation of the stem cells resident. Some literatures states that these stem cells, the Hepatic Progenitor Cells (HPCs), are oval cells that have bipotential ability to be cholangiocytes and hepatocytes. However, the mechanisms of programming, activation of proliferation and maturation/differentiation … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 13 Jul 2017 · 9,286 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Dynamic of Afamin and Alpha-Fetoprotein Expression during Rat Liver DevelopmentIndriyani, Isabella Kurnia Liem, Puspita Eka Wuyung et al.Liver has a high level of Alpha-fetoprotein which is assumed to be important for mammalian development. However, Alpha-fetoprotein knockout studies in mice suggested that despite the absence of Alpha-fetoprotein, mice developed normally; the only abnormality observed was infertility in female mice. There are indications that Afamin, a protein that has a gene sequence located on the same chromosome as Alpha-fetoprotein, … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 5 Feb 2021 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractSerum Ornithine Carbamoyltransferase Activity and Correlation with Fatty Liver in Dairy Cows with Displaced AbomasumKen Onda, Reiichiro Sato, Yosuke Sasaki et al.Ornithine Carbamoyltransferase (OCT) is a hepatocyte-specific enzyme; elevated serum activity indicates liver damage. Displaced abomasum frequently occurs around the time of parturition in dairy cattle and is associated with fatty liver. We analyzed serum OCT activities to investigate the relationship between displaced abomasum and fatty liver. Lactating Holstein cows, 75 clinically healthy and 22 with displaced abomasum, were used. Serum … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 3 · 13 Jul 2016 · 7,660 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepatotoxicity Due to Histamine Trifluoro-Methyl Toluidide, Amthamine, R-(-)-α-Methyl Histamine and Clobenpropit (H1R-H4R-Agonists, Respectively) in Rabbit Experimental ModelTrivendra Tripathi, Aijaz Ahmed Khan, Mohammad Shahid et al.Problem statement: Since in vivo studies looking for toxicological impact of histamine receptors-agonists in experimental models are fragmentary, the present study was designed to delineate the histopathological and biochemical changes in livers of rabbits treated with histamine receptors (H1R-H4R)-agonists. Approach: The cohort comprised of six groups (Group I control and Group II-VI treated) containing five rabbits each. Control-group received vehicle … …Current Research in Medicine, Vol. 1, Issue 1 · 30 Jun 2010 · 8,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractSignaling Pathways Involved In Dengue-2 Virus Infection Induced RANTES OverexpressionYing-Ray Lee, Huan-Yao Lei, Shun-Hua Chen et al.Dengue viruses participate in liver inflammation by inducting the expression of various chemokines including Regulated on Activation Normal T-cell Expressed and Secreted (RANTES). However, the underlying signaling remains unknown. Here, we reveal that Ras, Raf-1 and three mitogen-activated protein kinases (MAPKs) p38, extracellular signal-regulated kinase (Erk), and c-jun-NH2-terminal kinase (JNK) can be activated or phosphorylated in dengue-2 virus infected hepatocyte … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractTherapeutic Effects of Phyllanthus Species: Induction of TNF-α-mediated Apoptosis in HepG2 Hepatocellular Carcinoma CellsSripathi M. Sureban, Dharmalingam Subramaniam, Paramasivam Rajendran et al.Phyllanthus species, especially P. amarus is a medicinal plant with hepatoprotective activity, believed to occur in part by inhibiting hepatitis B virus function. The pathogenesis mechanism of viral hepatitis is closely related to hepatocyte necrosis apoptosis. The aim of our study was to investigate the in vitro effects of extracts from three Phyllanthus species, P. urinaria, P. amarus and P. … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2007 · 9,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractFerulic Acid in Chinese Herbal Medicine: Regulating Autophagy for Oxidative Damage ReductionZhiyuan Lv, Qiaozhen Zhao, Shanbin Chen et al.Ferulic Acid (FA) is the primary functional component in herbal plants and traditional fermented foods. To comprehend the mechanism of action of ferulic acid, in terms of its regulation of autophagy, antioxidants and the inhibition of inflammatory pathways, the study was conducted.
