Extracted crude LOX was assayed spectrophotometrically for raw, ripe wild pear lipoxygenase and after 7-day storage. The effects of different buffers and pHs, substrate preparations, temperature, inhibitors and metal ions on LOX activity were evaluated at three conditions. The enzyme was most active with Hcl-Tris buffer at a pH of 7.5 and a temperature of 40oC. The best substrate was the first preparation with linoleic acid/Tween 20 at a ratio of 1:1. The kinetic parameters determined under the best conditions were a Km of 6.5 mM and a Vmax of 0.9 unit/mg protein for raw condition, 5.8 mM and a Vmax of 0.95 unit/mg protein for ripe condition and 5 mM and a Vmax of 1.1 unit/mg protein obtained after storage. The enzyme was heat-labile. It was shown that crude wild pear LOX is fully active at room temperature (20-30oC), while the best activity occurred at 35oC for Lox after storage that activity of lipoxygenase increased up to 130%. The results showed that lipoxygenase inhibitory activity of chemical compounds and standard compound decreased in the order of ascorbic acid > nicotinic acid > benzoic acid > DL-α-tocopherol. Monovalent and trivalent ions are inhibitors of LOX and divalent ions except Zncl2 are activators of LOX.","PeriodicalId":13887,"journal":{"name":"International journal of Advanced Biological and Biomedical Research","volume":"12 1","pages":"17-28"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78881241","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}

Hence, it is very important to find practical and effective methods for reducing the use of pesticides in environment as well as the increasing the efficiency of these compounds. Addition of adjuvants to spray solutions could be considered as one of these methods. Greenhouse studies were conducted using a complete randomized design with a factorial arrangement during 2015-2016 to evaluate the impact of different adjuvants (citogate, canola oil, and castor oil) at concentrations of 0.1 and 0.2 (%v/v) with 5, 10, 20, 30 and 40 g a.i. ha-1 of tribenuron methyl herbicide to control common lambsquarters. Results showed that all applied adjuvants enhanced the efficacy of tribenuron methyl in decreasing the biomass of common lambsquarters. Efficacy of this herbicide increased with enhancing its concentrations. The required dose of herbicide to give 50 per cent common lambsquarters control (ED50) for no adjuvant, citogate, castor oil, and canola oil application (0.2 (%v/v)) was 21.24, 11.48, 11.65, and 11.81 g a.i. ha-1, respectively. Totally the application of citogate and canola oil had the highest and the lowest impact on tribenuron methyl performance to control of common lambsquarters respectively. Also, the Relative Potency values were significantly increased when adjuvants were added to this herbicide. The results revealed that the use of citogate and vegetable oils can increase the efficiency tribenuron methyl, and reduce the application rate of this herbicide in agro ecosystems.","PeriodicalId":13887,"journal":{"name":"International journal of Advanced Biological and Biomedical Research","volume":"763 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78816056","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}

After collecting clinical data and performing Laboratory tests, DNA samples were extracted from blood samples by phenol chloroform method, and polymorphisms in specimens were examined by specific genotypes. Data were analyzed by SPSS22 software.Results: There was no correlation between Taq1 and Fok1 polymorphisms with both healthy and healthy patients. Although the frequency of CT genotype was higher in both groups, this difference was not significant (P-Value > 0.05).Conclusion: No evidence was found that VDR gene polymorphisms play a role in the risk of type 2 diabetes and obesity in Iranian subjects.

The influence of temperature was meaningful on germination percentage, mean time germination, shoot and root length, plumule dry weight, plumule fresh weight, root dry weight and root fresh weight. The rate of germination, germination percentage, as well as seedling growth and establishment were significantly lowered with the rise of stress levels using PEG. Control treatment and 15oC had obtained the highest germination percentage, mean time germination, shoot and root length, germination uniformity, plumule dry and fresh weight, root dry and fresh weight, and seed stamina index.
