It lives in muddy places, rice paddies, and slow-flowing currents areas. It has a unique morphological elongated body which is similar to snake and covered with a thick layer of the mucus. The objective of this study is to screen the cytotoxic activity of eel skin mucus extracts and to evaluate the mechanism of cell death whether it is apoptosis or necrosis based on caspases activity assays. For this purpose; eel skin mucus was collected from healthy fresh eels to prepare aqueous and methanol extracts. Preliminary cytotoxicity study was demonstrated against Non-small-cell lung carcinoma cell line (A549) using cell viability assay which revealed that methanol extract is more potent than aqueous extract; the revealed data was based on the response of ESM methanol and aqueous extracts to the relevant IC50 concentrations as IC50 values were 621±0.09 µg/mL and 845 ± 0.25 µg/mL respectively. Subsequently, the mechanism of cell death induced cell death through triggering apoptosis by the activation of caspase-3/7, 8 and 9. In conclusion, the present study has revealed the cytotoxic potentials of eel skin mucus which may lead to the development of new anticancer agents.

To determine the seasonal and spatial distributions of juvenile maid, a small-mesh seine net was employed monthly at seven selected coastal sites during the period from November 2013 through October 2014. Semicircular sweeps of the 30 m long, two-meters high seine covered an area of approximately 1,400 m2. Juvenile maid were captured at most of the sampling sites during the entire investigation period, but mainly in spring and summer, indicating a wide coastal distribution of this species. The highest catches of juveniles occurred in May with an average of 30.2 kg per sweep, corresponding to a density of 22 g/m2. Catches of juveniles from sampling sites in or just south of the Kuwait Bay, near prime maid fishing grounds, were much higher than those from more southerly sampling sites. The captured maid ranged in total length (TL) from 18 to 179 mm, with a high peak at 41 to 50 mm. By-catch included thirty species, with hasoom (Sillago sihama), Imchawah (Diplodus sargus kotschyi), and yowaff (Nematalosa nasus) being the most common. The by-catch consisted mostly of juveniles with lengths less than100 mm TL, showing the importance of the intertidal and coastal waters for many species.","PeriodicalId":355315,"journal":{"name":"Journal of Agricultural and Marine Sciences [JAMS]","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126154133","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}

These changes have affected wind speeds, atmospheric and sea surface temperature, thermohaline stratification, shoaling of the oxycline, and dust/iron inputs. A decrease in nitrate supply of the photic layer have caused an increase in annual frequency of harmful algal blooms and fish kills. Along with that, a decrease in diatom biomass and a shift from red Noctiluca to green Noctiluca during the northeast monsoon was observed during the last two decades, Even though these are the same species they have very different nutritional modes. The red one is a heterotroph with a preference for grazing diatoms, while the green one has a symbiont and thus it is a mixotroph. Recent results suggest that this shift may be caused by the shoaling oxycline since the green one grows better under low oxygen because the symbiont produces oxygen for its host. The western Arabian Sea is temporally and spatially complex. With the recent advances in remote sensing of the ocean, a further understanding of these temporal and spatial changes can be gained through analyzing frequent images with opportunistic ground-truthing.","PeriodicalId":355315,"journal":{"name":"Journal of Agricultural and Marine Sciences [JAMS]","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123796380","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 objective of the research was to investigate the presence of the phytopathogenic gungus Fusarium oxysporum the causal agent of the disease in zucchini fields. Forty five isolates of F. oxysporum were isolated from four locations in province of Dyala during 2014-2015. Isolate Foq9 was most virulent in the pathogenicity test in vitro. Twenty nine isolates of them amplified their DNA positively with the universal primer of F. oxysporum in the polymerase chain reaction technique (PCR). In vitro significant suppression efficiency were observed of the fungicides Topsin M 70 WP (Tm) and Tecto 500 SC (Tc) and two botanical extract solution extracted from Garlic (Gr) and Ginger (Gn) against the pathogen on the potato sucrose agar (PSA). In greenhouse experiments all of the agents decreased the percentage of disease incidence and severity significantly, while the tetra-inoculum (Tm+Tc+Gr+Gn) was superior which exhibited 0% disease incidence and severity compared to the negative control which was 95%, 79% respectively, also the combined application of the botanical extracts (Gr+Gn) reduced the disease incidence and severity significantly.

Two field experiments, conducted in Oman, showed that muskmelon cv. Sawadi grafted on six cucurbit rootstocks gave high grafting success: 97.6-99.1% (avg. 98.6%) and 92.4-96.9% (avg. 95.3%) under field conditions in fall 2012 and spring 2013 respectively. No significant differences were observed between seasons among the six treatments and a non-grafted control in consumer preference for odor and firmness, fruit shape, flesh vitamin C, micronutrient content and TSS (sucrose %) or pH in spring 2013 (P > 0.05). The concentration of phosphorus and sodium significantly decreased in both seasons in all treatments in comparison to the control (P > 0.05). In both seasons potassium content significantly increased when Rsscih7458 and Mubyeongjangsoo rootstocks were used (P < 0.05). Strong Tosa rootstocks showed zero graft failure, high resistance to vine decline disease, high yield production and higher TSS (sucrose %) as compared to other rootstocks. Strong Tosa and Tetsukabuto rootstocks showed significantly higher consumer acceptance for rind color, flesh color and overall consumer acceptance in spring 2013 and was also less affected by seasonal changes. Results suggested that by grafting muskmelon cv. Sawadi some quality attributes may be improved in addition to the increased level of resistance to disease. However, additional trials are required to make final recommendations for the farming community.","PeriodicalId":355315,"journal":{"name":"Journal of Agricultural and Marine Sciences [JAMS]","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124091738","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}
