It may occur anywhere in the production system, from the oil/gas well bottom to the final transfer of produced gas or oil to the refinery. Internal corrosion of carbon steel pipelines is a common and serious problem in oil and gas production, which is designed for long-term operation. It involves an interaction between the metal wall and the flowing fluids. This problem has caused the consideration of many corrosion control programs and research in various oilfields around the world. There is global use of carbon steels as materials of construction for pipes in the oil and gas industries.  Compounds triazoles and their derivatives have attracted huge attention due to their simple preparation and superior corrosion inhibition activity towards mild steel in acidic environments.

Methods: In this cross-sectional study, we recruited treatment-naive patients with chronic HCV. The rs738409 (PNPLA3) and rs641738 (MBOAT7) polymorphisms were assessed by Real-Time PCR. We utilized the METAVIR‐Score to classify the degree of hepatic fibrosis and necroinflammatory activity. Results: A total of 93 patients (mean age 42.72 ± 10.46; males = 49.5%) were included. Our analysis showed that 10.8% of the patients had GG genotype of the PNPLA3 gene and 46.2% had TT genotype of the MBOAT7 gene.  Compared to combined CC and GC genotypes, carriers of GG genotype in PNPLA3 gene were more likely to be males (p =0.041), have higher fibrosis grade (p =0.043), have higher serum creatinine (p =0.036), higher TSH (p =0.017) and higher viral load (p =0.045). Notably, we found a significant association between TT genotype in MBOAT7 and advanced fibrosis only (but not with necroinflammation (p >0.05). Our multivariate analysis showed that the GG genotype in the PNPLA3 gene and TT genotype in the MBOAT7 gene were independent predictors of advanced fibrosis. Conclusion: PNPLA3 GG genotype and MBOAT7 TT genotype are independent predictors for hepatic fibrosis, and thus might be linked to faster disease progression.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88353993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Ivory Coast, this plant is widespread in several regions with different climatic conditions. The aim of our study is to compare the effects of aqueous extracts of Blighia sapida harvested in three Ivorian regions on the biochemical parameters of rats made hypertensive by a fructose diet. Rats (20) were fed a high fructose diet (70% fructose, 10% fat, 20% protein) for 30 days. Then blood pressure was measured from an armband to the tail of the rats. Finally, biochemical and lipid parameters were measured before and after the fructose-enriched diet. All rats fed the high-fructose diet had similar rates of hypertension (SBP = 160.0 ± 0.07 mmHg; DBP = 141.5 ± 1.21 mmHg; HR = 325.7 ± 1.52 beats/min) and a change in dosing parameters. Aqueous extracts of Blighia sapida from Adzopé (EAA) and Korhogo (EAK) administered to hypertensive rats normalized the previously increased cardiovascular, biochemical, and lipid parameters compared to control rats (healthy and untreated diseased rats). However, the aqueous extract of Blighia sapida of Adzopé (EAA) showed the best effects on hypertension compared to the aqueous extract of Blighia sapida of Korhogo (EAK). Indeed, the more humid the region and the climate, the more effective the extract is. The regulating effect of aqueous extracts of Blighia sapida on blood pressure, therefore, differs from one region to another with different climatic conditions. This would explain its use in traditional medicine in certain climatic zones compared to others where its therapeutic effects would be unknown because less. Adzopé would, therefore, be the best region where Blighia sapida should be harvested for the optimal treatment of high blood pressure.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88226755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endocrine organs, such as the thyroid, kidneys, testis, and placenta, are sensitive to the toxic effects of Cd. Ziziphus spina-christi fruit has been claimed to exhibit potent anti-oxidative and free radical scavenging abilities. Aim : This work is mainly designed to evaluate the potential modulatory role of Z. spina-christi fruit extract against thyroid, kidney, and testicular impairments associated with cadmium chloride (Cd Cl2) exposure in rats. Material & Methods : Twenty-four male rats were divided into four groups (n = 6): group I served as control, group II was supplemented daily with Ziziphus fruit extract (200 mg/kg b.wt), group III was treated with CdCl2 (5 mg/kg b.wt) each other day, and group IV was administered with CdCl2 simultaneously with Ziziphus fruit extract. The experiment was conducted for 45 days. At the end of the experiment, the rats of all groups were weighed and sacrificed, and the thyroid, kidneys, and testes were immediately excised, and processed for histological and biochemical evaluation of antioxidants and apoptosis. Also, blood samples were collected and analyzed to estimate the appropriate biochemical parameters for each organ. Results: In CdCl2 treated rats, the levels of serum hormones (TSH, T3, T4, FSH, LH, and testosterone) were significantly decreased if compared with control. Additionally, the levels of calcium, phosphorus ions, and albumin were also decreased while the level of total cholesterol was significantly elevated compared with the control. Moreover, the levels SOD and GSH were significantly lowered while the level of MDA was elevated in the tissues of all target organs (thyroid, kidney, and testes). Also, the sections from the thyroid, kidney, and testes displayed pronounced deleterious histological changes. Furthermore, the mean % values of positively expressed cells for caspase-3 and annexin-v markers were significantly elevated in the thyroid and testicular tissues of CdCl2 received rats compared to control. Co-supplementation of Z. spina-christi fruit extract to CdCl2 exposed rats successfully restored the altered biochemical and histological and apoptotic changes induced by cadmium . Conclusion: It is concluded that Z. spina-christi fruit extract has a powerful protective role against Cd-induced deleterious biochemical and histological changes in the thyroid, kidneys, and testes of male rats.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"92 7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77282186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to assess the contamination of Bambara groundnuts, by the most dangerous and widespread mycotoxins in Africa (aflatoxins), especially in Benin, this study was conducted in Cotonou (Benin) main markets. Thirty-five (35) samples of Bambara groundnuts were collected from six (6) different markets in Cotonou. The fungi are isolated and identified morphologically on different media after direct culture. The species of Aspergillus section Flavi aflatoxigenic potential are evaluated and the contamination of samples by aflatoxins was determined by Thin Layer Chromatography (TLC). The results of this study showed that the average water content of Bambara groundnuts samples ranged from 4.85 to 9.35%. The main species of mold isolated are Mucor spp., Rhizopus spp., Alternaria sp., and Aspergillus spp. Forty-six (46) strains of Aspergillus section Flavi were isolated on Potatoes Dextrose Agar (PDA). All of them have been identified as aflatoxigenic strains and were divided into different groups according to their morphological appearance and secondary metabolites. Twentytwo samples (62.85%) of Bambara groundnuts were contaminated by aflatoxins.
