Cancer incidences show inconsistency between emerging and developed nations. Epidemiologic findings intensely propose that incidence of cancer are predisposed by environmental factors including diet, which is essentially unavoidable. Strategies to prevent cancer comprise overlapping approaches viz. Dietary cancer prevention or chemoprevention. Naturally occurring constituents or pharmacological agents prevent or reverse the initiation phase of carcinogenesis or arrest at progression of carcinogenesis through chemoprevention. Cancer prevention through diet may be possible by the intake of fruits and vegetables. Significant consideration has been given in finding plant-derived dietary agents, which can be developed as promising chemo preventives. One such compound is chrysin (5,7-dihydroxylflavone). It has been shown to possess significant anti-inflammatory, antioxidant and anti-carcinogenic properties. Recently significant progress has been made in studying the biological effects of chrysin at cellular and molecular levels. This review scrutinizes the anticancer effects of chrysin, its considerable potential for development as a cancer chemo preventive agent.","PeriodicalId":12012,"journal":{"name":"European Journal of Experimental Biology","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76229398","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}

The University Campus included: The University of Peshawar, Islamia College University, The University of Agriculture Peshawar, Pakistan Forest Institute and the New Developmental Research Farm, The University of Agriculture Peshawar were the main studied areas. In the selected areas P. hysterophorus distribution was measured in the academic, residential and research farm areas. Moreover, the survey also investigated the impact of parthenium weed upon native weeds flora inside the University campus. A 1m2 quadrat was used to collect the data. During the survey, a total of 32 weeds species were recorded belonging to 18 different families and 32 genera, the life cycle of 23 weeds were annual while 9 weeds have perennial life cycle. The data were recorded on absolute density (%), relative density (%), absolute frequency (%), relative frequency (%) and importance values (%) of parthenium weed and others flora. The data showed that parthenium weed was most dominant species having 76.8 m-2 plants density in the NDF and (32.0 m-2) plants in Islamia University. However, the highest frequency (100%) of P. hysterophorus was observed for The University of Agriculture, while minimum (80%) occurred in Agronomy field. Moreover the relative frequency of P. hysterophorus was maximum (25%) seemed for Islamia College; whereas, its minimum (12.9%) at Agronomy field. Lastly, the Importance Value of Parthenium indicates the highest (45.98%) at Dairy farm followed by (40.33 %) at Horticulture field’s area. In conclusion, the Parthenium weed become more problematic and replaces all the native flora in the non-crop area specially Dicanthium annulatum a native grass specie on the on the ridges of the field being replaced by parthenium. Due to no proper management and high growth rate, nowadays it becomes as super weed in the KPK and especially in the Pakistan. So, the management of Parthenium weed requires the call attention from the Govt. policy maker and proper quarantine inspection to conserve the native flora and field crops to get maximum crop yield.","PeriodicalId":12012,"journal":{"name":"European Journal of Experimental Biology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89690794","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}

We also assume that hydrogen peroxide (H2O2) formed during redox reactions is inducer of Sirt1 gene. Methods and Results: Atrial Cardiomyocyts HL1 cells were cultured in Claycomb medium with 10% FBS, 100μmol/L norepinephrine, and 4 mmol/L L-glutamine (Invitrogen, Carlsbad, CA) in gelatin coated flasks. Cells were maintained at 37°C in an atmosphere containing 5% CO2. Cells were then incubated with either 50 μM and 0.25 mM ASA for 48 h in the same medium. Respective controls were maintained with alcohol alone. At the end of the treatment, the medium was removed and the cells were washed with PBS and harvested in Trizol® for isolation of RNA. RT-PCR was performed for the analysis of gene expression. Our results in cultured HL1 cardiomyocytes showed ASA treament induced Sirt1 and Sirt4 genes via H2O2 generation. Increase in Sirt1 gene activated PGC1α and Tfam gene. ASA have also induced antioxidant enzymes, glutathione peroxidase (GPX) and catalase (CAT) gene. Conclusion: We conclude from our results that ASA is a potential anti-atherosclerotic drug and an increase in Sirt1 gene further suggest that it can induce anti-inflammatory action. It can also interfere with Nfkb signaling pathway that can prevent foam cell formation. However, specific overexpression of PGC1α and Tfam gene in HL1 cardiomyocyte can increase mitochondrial biogenesis and prevent the development of heart failure.","PeriodicalId":12012,"journal":{"name":"European Journal of Experimental Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89802568","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}

The genus Aspergillus was the dominant genus having 49.6% of the total fungal isolates, followed by Penicillium and Acremonium.

A common co-morbidity associated with cardiovascular disease is depression. We have previously shown that paroxetine, a selective serotonin re-uptake inhibitor widely prescribed as antidepressant, improves cardiac contractility by preserving fractional shortening (FS) of AR rat hearts. In failing hearts, decrease of the ability of the myocardium to generate an effective shortness velocity is well correlated with the shift of myosin isoform distribution from α to β- MyHC expression. In order to understand the molecular mechanism involved in the improvement of FS after paroxetine treatment, we verified the expression of genes involved in heart contractility and hypertrophy. Methods and Findings: Male Wistar rats were submitted to AR surgery, by retrograde puncture of the aortic valves leaflets, or sham surgery. Morphofunctional variables of the hearts were analyzed by echocardiograms at weeks 4 and 8 after the induction of AR. At week 8 the animals were euthanized for tissue collection and posterior analysis of gene expression by RTq-PCR. Paroxetine treatment for 4 weeks in AR rats reduced the gene expression of β-MyHC and its myomiRs (miR-208 and miR-499). BNP, a molecular biomarker of hypertrophy, also showed their gene expression reduction after paroxetine treatment. Conclusion: These results suggest that paroxetine treatment improves FS in AR hearts through reductions in the expression of several genes involved with cardiac contractility and hypertrophy.","PeriodicalId":12012,"journal":{"name":"European Journal of Experimental Biology","volume":"58 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77809784","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}
