    BACKGROUND: Treatment of cancer with chemo-radiotherapy causes severe side effects due to cytotoxic effects towards normal tissues which often results in morbidity. Therefore, developing anticancer agents which can selectively target the cancer cells and cause less side effects are the main objectives of the new therapeutic strategies for treatment advanced or metastatic cancers. Newcastle disease virus strains AF2240 and V4-UPM were shown to be cytolytic against various cancer cells in-vitro and very effective as antileukemicagents.

    METHODS: 45 rats at 6 weeks of age, were randomly assigned to nine groups with 5 rats in each group, both azoxymethane (AOM) and 5-Fluorouracil (5-FU) were given to rats according to the body weight. NDV virus strains (AF2240 and V4-UPM) doses were determined to rats according to CD50 resulted from MTT assay. After 8 doses of NDV strians and 5-FU, tissue sections preparations and histopathological study of rats' organs were done.

    RESULTS: In this article morphological changes of rats' organs, especially in livers, after treatment with a colon carcinogen (azoxymethane) and Newcastle disease virus strains have been recorded. We observed liver damage caused by AOM evidenced by morphological changes and enzymatic elevation were protected by the oncolytic viruses sections. Also we found that combination treatment NDV with 5-FU had greater antitumor efficacy than treatment with NDV or 5-FU alone.

    CONCLUSION: We noted morphological changes in liver and other rats' organs due to a chemical carcinogen and their protection by NDV AF2240 and NDV V4-UPM seems to be most protective.

    PMID: 12085634
    The specific texture on B-scan images is believed to be related to both ultrasound machine characteristics and tissue properties, i.e., the pathological states of the soft tissue. Therefore, for classification, features can be extracted with the use of image texture analysis techniques. In this paper a novel fuzzy approach for texture characterization is used for classification of normal liver and diffused liver diseases, here fatty liver, liver cirrhosis, and hepatitis are emphasized. The texture analysis techniques are diversified by the existence of several approaches. We propose fuzzy features for the analysis of the texture image. For this, a membership function is constructed to represent the effect of the neighboring pixels on the current pixel in a window. Using these membership function values, we find a feature by weighted average method for the current pixel. This is repeated for all pixels in the window treating each time one pixel as the current pixel. Using these fuzzy based features, we derive three descriptors: maximum, entropy, and energy as used in co-occurrence method, for each window.

    Stem cells can multiply into more cells with similar types in an undifferentiated form and differentiate into other types of cells. The great success and key essence of stem cell technology is the isolation of high-quality Mesenchymal Stem Cells (MSCs) with high potency, either with multipotent or pluripotent property. In this line, Stem cells from Human Exfoliated Deciduous teeth (SHEDs) are highly proliferative stem cells from dental pulp and have multipoint differentiation capacity. These cells play a pivotal role in regenerative medicine, such as cell repair associated with neurodegenerative, hepatobiliary, and pancreatic diseases. In addition, stem cell therapy has been widely used to regulate immune response and repair of tissue lesions. This overview captured the differential biological characteristics, and the potential role of stem cell technology and paid special attention to human welfare SHEDs in eliminating the above-mentioned diseases. This review provides further insights into stem cell technology by expanding the therapeutic potential of SHEDs in tissue engineering and cell organ repairs.

    PMID: 22049042 DOI: 10.4269/ajtmh.2011.11-0404
    We report a case of visceral pentastomiasis caused by Armillifer moniliformis in a 70-year-old aboriginal farmer from rural Malaysian Borneo. The patient complained of upper abdominal pain, jaundice, and loss of weight. Radiological investigations and subsequent histopathological examination revealed an adenocarcinoma of the pancreas with an adjacent liver nodule containing a nymph of A. moniliformis. This report constitutes the first documented human pentastomid infection in the whole of Malaysia after nearly 40 years, and it is the third description from Malaysian Borneo. Cases of human and animal pentastomiasis in Malaysia are discussed.

    The incidence of obesity is increasing in Asia, with implications on gastrointestinal (GI) and liver diseases. The Gut and Obesity in Asia Workgroup comprises regional experts with the aim of studying relationship between obesity and the GI and liver diseases in Asia. Through literature review and the modified Delphi process, consensus statements examining the impact of obesity on esophageal, gastric, pancreatic, colorectal, and liver diseases, exploring relationship between gut microbiome and obesity, and assessing obesity therapies have been produced by the Gut and Obesity in Asia Workgroup. Sixteen experts participated with 9/15 statements having strong consensus (>80% agreement). The prevalence of obesity in Asia is increasing (100% percentage agreement in brackets), and this increased prevalence of obesity will result in a greater burden of obesity-related GI and liver diseases (93.8%). There was consensus that obesity increases the risk of gastric cancer (75%) and colorectal neoplasia (87.5%). Obesity was also associated with Barrett's esophagus and esophageal adenocarcinoma (66.7%) and pancreatic cancer (66.7%) in Asia. The prevalence of non-alcoholic fatty liver disease (NAFLD) in Asia is on the rise (100%), and the risk of NAFLD in Asia (100%) is increased by obesity. Obesity is a risk factor for the development of hepatocellular carcinoma (93.8%). Regarding therapy, it was agreed that bariatric surgery was an effective treatment modality for obesity (93.8%) but there was less agreement on its benefit for NAFLD (62.5%). These experts' consensus on obesity and GI diseases in Asia forms the basis for further research, and its translation into addressing this emerging issue.

  11. Fulltext Interventions for preventing and managing advanced liver disease in cystic fibrosis
    Palaniappan SK, Than NN, Thein AW, van Mourik I
    Cochrane Database Syst Rev, 2020 03 30;3:CD012056.
    PMID: 32227478 DOI: 10.1002/14651858.CD012056.pub3
    BACKGROUND: Cystic fibrosis is an autosomal recessive inherited defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene resulting in abnormal regulation of salt and water movement across the membranes. In the liver this leads to focal biliary fibrosis resulting in progressive portal hypertension and end-stage liver disease in some individuals. This can be asymptomatic, but may lead to splenomegaly and hypersplenism, development of varices and variceal bleeding, and ascites; it has negative impact on overall nutritional status and respiratory function in this population. Prognosis is poor once significant portal hypertension is established. The role and outcome of various interventions for managing advanced liver disease (non-malignant end stage disease) in people with cystic fibrosis is currently unidentified. This is an updated version of a previously published review.

    OBJECTIVES: To review and assess the efficacy of currently available treatment options for preventing and managing advanced liver disease in children and adults with cystic fibrosis.

    SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Date of last search: 19 November 2019. We also searched the reference lists of relevant articles and reviews and online trials registries. Date of last search: 01 January 2020.

    SELECTION CRITERIA: Any published and unpublished randomised controlled trials and quasi-randomised controlled trials of advanced liver disease in cystic fibrosis with cirrhosis or liver failure, portal hypertension or variceal bleeding (or both).

    DATA COLLECTION AND ANALYSIS: Authors independently examined titles and abstracts to identify potentially relevant trials, but none were eligible for inclusion in this review.

    MAIN RESULTS: A comprehensive search of the literature did not identify any published eligible randomised controlled trials.

    AUTHORS' CONCLUSIONS: In order to develop the best source of evidence, there is a need to undertake randomised controlled trials of interventions for preventing and managing advanced liver disease in adults and children with cystic fibrosis.

    Transient abnormal myelopoiesis (TAM) occurs in approximately 10% of neonates with Down syndrome. In most cases it resolves spontaneously. Life threatening complications such as cardiopulmonary and liver diseases have been described. We present here two cases which suggest that management of TAM in selected cases will have to be more aggressive.

  13. Fulltext Automatic liver segmentation on Computed Tomography using random walkers for treatment planning
    Moghbel M, Mashohor S, Mahmud R, Saripan MI
    EXCLI J, 2016;15:500-517.
    PMID: 28096782 DOI: 10.17179/excli2016-473
    Segmentation of the liver from Computed Tomography (CT) volumes plays an important role during the choice of treatment strategies for liver diseases. Despite lots of attention, liver segmentation remains a challenging task due to the lack of visible edges on most boundaries of the liver coupled with high variability of both intensity patterns and anatomical appearances with all these difficulties becoming more prominent in pathological livers. To achieve a more accurate segmentation, a random walker based framework is proposed that can segment contrast-enhanced livers CT images with great accuracy and speed. Based on the location of the right lung lobe, the liver dome is automatically detected thus eliminating the need for manual initialization. The computational requirements are further minimized utilizing rib-caged area segmentation, the liver is then extracted by utilizing random walker method. The proposed method was able to achieve one of the highest accuracies reported in the literature against a mixed healthy and pathological liver dataset compared to other segmentation methods with an overlap error of 4.47 % and dice similarity coefficient of 0.94 while it showed exceptional accuracy on segmenting the pathological livers with an overlap error of 5.95 % and dice similarity coefficient of 0.91.

  14. Fulltext Hepatoprotective Effects of Morinda citrifolia Leaf Extract on Ovariectomized Rats Fed with Thermoxidized Palm Oil Diet: Evidence at Histological and Ultrastructural Level
    Chong CLG, Hussan F, Othman F
    Oxid Med Cell Longev, 2019;2019:9714302.
    PMID: 31827717 DOI: 10.1155/2019/9714302
    Morinda citrifolia (Rubiaceae) or Noni was previously reported to have leaf with broad therapeutic property whereas the fruit was rarely described as medicinal. Ironically, extensive research and review has been done on the fruit and little was known about the therapeutic activity of the leaf as a medicinal food. The aim of this study was to investigate the therapeutic effects of Morinda citrifolia (MC) ethanolic leaf extract on the hepatic structure and function in postmenopausal rats fed with thermoxidized palm oil (TPO) diet. Thirty eight female Sprague Dawley rats were divided into five groups: sham (Sham), ovariectomized (OVX), ovariectomized and treated with simvastatin 10 mg/kg (OVX+ST), ovariectomized and supplemented with low dose MC 500 mg/kg (OVX+MCLD), and ovariectomized and supplemented with high dose MC 1000 mg/kg (OVX+MCHD). All the ovariectomized groups were fed with TPO diet whereas the Sham group was fed with normal diet. Consumption of TPO diet in postmenopausal rats resulted in obesity, significantly elevated (P < 0.05) liver oxidative stress marker; malondialdehyde (MDA), diffuse microvesicular steatosis, and defective mitochondria. Treatment with MC leaf extract prevented hepatic steatosis by significantly increasing (P < 0.05) the liver antioxidant enzyme SOD and GPx, significantly increasing (P < 0.05) ALP, decreasing liver lipids infiltration, preventing mitochondrial damage, and overall maintaining the normal liver histology and ultrastructure. In conclusion, we provided detailed histological and ultrastructural evidence showing hepatoprotective effects of MC leaf extract through its antioxidant mechanism.

    Evid Based Complement Alternat Med, 2011;2011:142739.
    PMID: 21318140 DOI: 10.1155/2011/142739
    The present study aims to determine the hepatoprotective effect of MARDI-produced virgin coconut oils, prepared by dried- or fermented-processed methods, using the paracetamol-induced liver damage in rats. Liver injury induced by 3 g/kg paracetamol increased the liver weight per 100 g bodyweight indicating liver damage. Histological observation also confirms liver damage indicated by the presence of inflammations and necrosis on the respective liver section. Interestingly, pretreatment of the rats with 10, but not 1 and 5, mL/kg of both VCOs significantly (P < .05) reduced the liver damage caused by the administration of paracetamol, which is further confirmed by the histological findings. In conclusion, VCO possessed hepatoprotective effect that requires further in-depth study.

    Elephantopus scaber has been traditionally used as liver tonic. However, the protective effect of E. scaber on ethanol-induced liver damage is still unclear. In this study, we have compared the in vivo hepatoprotective effect of E. scaber with Phyllanthus niruri on the ethanol-induced liver damage in mice. The total phenolic and total flavanoid content of E. scaber ethanol extract were determined in this study. Accelerating serum biochemical profiles (including AST, ALT, ALP, triglyceride, and total bilirubin) associated with fat drop and necrotic body in the liver section were observed in the mice treated with ethanol. Low concentration of E. scaber was able to reduce serum biochemical profiles and the fat accumulation in the liver. Furthermore, high concentration of E. scaber and positive control P. niruri were able to revert the liver damage, which is comparable to the normal control. Added to this, E. scaber did not possess any oral acute toxicity on mice. These results suggest the potential effect of this extract as a hepatoprotective agent towards-ethanol induced liver damage without any oral acute toxicity effect. These activities might be contributed, or at least in part, by its high total phenolic and flavonoid contents.

  18. Endoscopic ultrasound-guided injection therapy for hepatobiliary disease
    Ponnudurai R, Sachithanandan S, George A
    J Hepatobiliary Pancreat Sci, 2011 May;18(3):311-8.
    PMID: 21468788 DOI: 10.1007/s00534-010-0354-5
    Endoscopic ultrasound (EUS)-guided injection therapy is the new frontier in the management of patients with hepatobiliary disease. Celiac plexus block/neurolysis was the first form of injection therapy and has been validated in many subsequent trials. Cyst ablation therapy, fiducial insertion, angiography, portal hypertensive therapy, endoscopic portosystemic shunt creation, portal vein embolization and injection of chemotherapeutic/biologic agents for antitumor therapy are more recent uses and will be discussed. Celiac plexus neurolysis is currently well established in providing adjunct pain control in patients with advanced malignancy. There are limited data available for its use in benign conditions. EUS-guided ablative therapy for pancreatic cysts remains an area for future research but seems to have a role for small thin-walled non-septated cysts. EUS-guided implantation of fiducials is technically feasible but its exact impact on tumor regression is unknown. Several case reports have documented EUS-guided alcohol and thrombin injection into pseudoaneurysms and cyanoacrylate and coil embolization for variceal therapy. Injection of viral vectors and immunomodulating cell cultures as antitumor therapy has been described but the evidence is still preliminary and further data are awaited.

  19. Prealbumin rather than albumin is a more sensitive indicator of acute liver disease
    Yasmin MY, Aziz B, Nazim M, Madhavan RK
    Malays J Pathol, 1993 Dec;15(2):147-50.
    PMID: 8065177
    The changes in serum prealbumin (transthyretin) and serum albumin in acute and chronic liver diseases were investigated. Albumin has long been used as a useful indicator of liver function but serum prealbumin has recently been noted for its clinical significance in acute liver diseases. Serum prealbumin concentrations and liver function tests (albumin, bilirubin, alanine aminotransferase) were determined on blood obtained from normal donors (n = 148) and from patients suffering from liver diseases (n = 78) such as acute viral hepatitis, chronic active hepatitis, cirrhosis and hepatoma. The mean serum prealbumin concentration in normal subjects was 29.6 +/- 4.82 mg/dl while the mean serum prealbumin concentration in patients with liver disease was greatly reduced (acute viral hepatitis = 15.3 +/- 7.4mg/dl; chronic active hepatitis = 10.2 +/- 6.6mg/dl; cirrhosis = 9.9 +/- 6.4mg/dl and hepatoma = 10.7 +/- 4.2). Albumin concentrations dropped slightly (13% compared to control) in acute viral hepatitis but dropped markedly (28% compared to control) in chronic liver diseases. The study suggests that serum prealbumin concentration might be a more sensitive indicator than albumin in assessing liver dysfunction in acute liver diseases.
