1Effect of Exogenous Melatonin on Seed Germination and Seedling Growth in Melon(Cucumis melo L.) Under Salt Stress显示文摘An investigation was carried out to evaluate the effect of different application forms and concentrations of melatonin on germination and initial growth of melon plants in several different salinity conditions. We evaluated germination percentage and growth of seedlings and measured total chlorophyll content, relative electrolyte leakage, peroxidase activity, root viability, proline concentration, relative water content,Na^+/K^+ratio in green parts and K^+leakage from roots. Seed germination percentage under salt stress increased with treatments of 10 and50 μmol·L^(-1) melatonin. Seed treatment and plant watering with melatonin at 50 μmol·L^(-1) improved growth parameters and plants showed higher chlorophyll content as well as better biochemical parameters than non-treated plants. Results suggest that melatonin can alleviate the effect of salt stress during seed germination and first stages of plant development.José Luis Casta?ares Carlos Alberto Bouzo 2019Horticultural Plant Journal2019,5,2:15
2Direct-fed microbes: A tool for improving the utilization of low quality roughages in ruminants显示文摘For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of the rumen to improve production efficiency of different ruminant species. Removal and restriction of antibiotics subtherapeutic uses from ruminant diets has amplified interest in improving nutrient utilization and animal performance and search for more safe alternatives. Some bacterial and fungal microorganisms as a direct-fed microbial(DFM) can be the most suitable solutions. Microorganisms that are commonly used in DFM for ruminants may be classified mainly as lactic acid producing bacteria(LAB), lactic acid utilizing bacteria(LUB), or other microorganism's species like Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, Bacillus, Propionibacterium, Megasphaera elsdenii and Prevotellabryantii, in addition to some fungal species of yeast such as Saccharomyces and Aspergillus. A definitive mode of action for bacterial or fungal DFM has not been established; although a variety of mechanisms have been suggested. Bacterial DFM potentially moderate rumen conditions, and improve weight gain and feed efficiency. Fungal DFM may reduce harmful oxygen from the rumen, prevent excess lactate production, increase feed digestibility, and alter rumen fermentation patterns. DFM may also compete with and inhibit the growth of pathogens, immune system modulation, and modulate microbial balance in the gastrointestinal tract. Improved dry matter intake, milk yield, fat corrected milk yield and milk fat content were obtained with DFM administration. However, the response to DFM is not constant; depending on dosages, feeding times and frequencies, and strains of DFM. Nonetheless, recent studies have supported the positive effects of DFM on ruminant performance.Mona M Y Elghandour Abdelfattah Z M Salem Jose S Martínez Castaeda Luis M Camacho Ahmed E Kholif Juan C Vázquez Chagoyán 2015Journal of Integrative Agriculture2015,14,3:7
3Effects of six months losartan administration on liver fibrosis in chronic hepatitis C patients: A pilot study显示文摘AIM: To evaluate the safety and efficacy of chronic administration of losartan on hepatic fibrosis in chronic hepatitis C patients. METHODS: Fourteen patients with chronic hepatitis C non-responders (n = 10), with contraindications (n = 2) or lack of compliance (n = 2) to interferon plus ribavirin therapy and liver fibrosis were enrolled. Liver and renal function test, clinical evaluation, and liver biopsies were performed at baseline and after losartan administration at a dose of 50 mg/d during the 6 mo. The control group composed of nine patients with the same inclusion criteria and paired liver biopsies (interval 6-14 mo). Histological activity index (HAI) with fibrosis stage was assessed under blind conditions by means of Ishak's score. Subendothelial fibrosis was evaluated by digital image analyses. RESULTS: The changes in the fibrosis stage were significantly different between losartan group (decrease of 0.5±1.3) and controls (increase of 0.89±1.27; P<0.03). In the treated patients, a decrease in fibrosis stage was observed in 7/14 patients vs 1/9 control patients (P<0.04). A decrease in sub-endothelial fibrosis was observed in the losartan group. No differences were found in HAI after losartan administration. Acute and chronic decreases in systolic arterial pressures (P<0.05) were observed after the losartan administration, without changes in mean arterial pressure or renal function. CONCLUSION: Chronic AT-Ⅱ type 1 receptor (AT1R) blockade may reduce liver fibrosis in patients with chronic hepatitis C.Silvia Sookoian María Alejandra Fernández Gustavo Casta(n|~)o 2005World Journal of Gastroenterology2005,11,48:7
4Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction.Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group 2017World Journal of Hepatology2017,9,27:6

6Common genetic variations in CLOCK transcription factor are associated with nonalcoholic fatty liver disease显示文摘AIM: To investigate the role of gene variants and derived haplotypes of the CLOCK transcription factor in nonalcoholic fatty liver disease (NAFLD) and their relation with the disease severity. METHODS: A total of 136 patients with NAFLD and 64 healthy individuals were studied. Liver biopsy was performed in 91 patients. Six tag SNPs showing a minor allele frequency > 10% (rs1554483 C/G; rs11932595 A/G; rs4580704 C/G; rs6843722 A/C; rs6850524 C/G and rs4864548 A/G) encompassing 117 kb of chromosome 4 and representing 115 polymorphic sites (r2 > 0.8) were genotyped. RESULTS: rs11932595 and rs6843722 showed signifi cant associations with NAFLD (empiric P = 0.0449 and 0.023, respectively). A significant association was also observed between clinical or histologic spectrum of NAFLD and rs1554483 (empiric P = 0.0399), rs6843722 (empiric P = 0.0229) and rs6850524 (empiric P = 0.00899) and between fibrosis score and rs1554483 (empiric P = 0.02697), rs6843722 (empiric P = 0.01898) and rs4864548 (empiric P = 0.02697). Test of haplotypic association showed that CLOCK gene variant haplotypes frequencies in NAFLD individuals significantly differed from those in controls (empiric P = 0.0097). CONCLUSION: Our study suggests a potential role of the CLOCK polymorphisms and their haplotypes insusceptibility to NAFLD and disease severity.Silvia Sookoian Gustavo Castao Carolina Gemma Tomas Fernández Gianotti Carlos Jose Pirola 2007World Journal of Gastroenterology2007,13,31:5
7Role of ABCC2 common variants in intrahepatic cholestasis of pregnancy显示文摘The pathogenesis of intrahepatic cholestasis of pregnancy (ICP), a disorder that adversely affects maternal wellbeing and fetal outcome, is unclear. However, multiple factors probably interact along with a genetic predisposition. We would like to add some comments on a paper recently published concerning the role of ABCB11 and ABCC2 polymorphisms in both ICP and contraceptive-induced cholestasis, especially in the light of our recently published findings about a positive association between ICP and ABCC2 common variants.Silvia Sookoian Gustavo Castao Carlos J Pirola 2008World Journal of Gastroenterology2008,14,13:4
