The only approved treatment for snakebite envenomation are antivenoms and their efficiency depends on the reference venom used in their production. It is important to mention that B. atrox is a species with wide geographic distribution, which can generate differences in the composition and phenotype of the venom between its different populations. This variability can be responsible for changes in the toxicological effects of snakebite among populations of the same species. With this in mind, the present study analyzed two venom samples from individuals from two Amazonian areas. Based on the results, differences in the abundance of the main families of toxins and their activities between both venoms were identified","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133159315","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}

Nowadays, researching of steroidal saponins (SE) is not present in Ecuador, a country where there is a less the science investment; in spite of owning endemic flora unexplored like Agave americana subps. andina (or the famous “penco azul”); it is a great specie for phytochemical and biotechnician studies. On the other hand, China has been the major SE productor since the end of twentieth century, and actuality, it progresses in prodrugs enhance. For this reason, the author of this short-paper explains how Ecuadorian biotechnicians can do an experimental design with a novel method of enzymatic hydrolysis. This innovative procedure uses a potato-dextrose subtract, which is a culture medium for yeasts of chaguarmishki. This method is useful for extracting O-glucuronidase, an enzyme that catalyze O-glycosides. These molecules are the active agent on Agave genus. Finally, the importance of this research is not for the advantages of SE on pharmaceutics or its human body effect; really, the principal benefit is the enhance of Ecuadorian pharmaceutical industry through a mass production with an investment on science investigation.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125646360","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}

West","doi":"10.3390/mol2net-05-06384","DOIUrl":"https://doi.org/10.3390/mol2net-05-06384","url":null,"abstract":"Blood disorders like B-thalassemia or sickle cell anaemia obligate patients to require constant blood transfusions. These, among others, make blood a highly demanded resource in the medical field. Blood has been obtained from in-vitro erythroid differentiation from embryonic stem cells or induced pluripotent stem cells, but this blood tends to produce embryonic haemoglobin. In this project, we aim to use a CRISPR/Cas9 modified version and an aptamer approach to alter the expression of the β-globin locus upregulating the gamma globin gene to produce foetal haemoglobin. Guide vectors were created targeting previously known sequences in the gamma haemoglobin gene. HEK cells were transfected with different combinations of CRISPR/Cas9 elements, as well as different combinations of aptamers/effectors, to test the amount of gene activation achieved. Gene expression analysis was performed through RTq/PCR. It was found that HbG activation can be achieved to some extent, however, the levels of gamma haemoglobin attained are very low compared with the normal levels of HbG expressed in other cell lines like K562. From the different grouping of vectors (dCas9 protein + aptamer/coating protein + activation effectors) tested, the combination of dCas9ES + PP7/PCP + VPH presented the best performance.

Abstract Bacterial resistance to antibiotics is an emerging problem worldwide; antimicrobials used in animal husbandry are the most important factor in the propagation of resistance genes, because the amount of antibiotics used in the animal industry is greater than in the medical field. Since phages constitute a safe alternative for the control of human pathogenic bacteria in food, this project aimed to isolate and characterize Salmonella spp. bacteriophages and use them to reduce the presence of this pathogen in poultry at the farm level, without the use of antibiotics. We obtained phage cocktails that showed lytic activity in vitro against 83% of the Salmonella strains isolated from poultry farms. The cocktails with the greatest spectrum of activity against Salmonella were obtained from nearby polluted rivers. We were able to eliminate the pathogen from the chicken intestine when phages were applied 48 hours before the animals were slaughtered, but it is necessary to maintain a permanent monitoring of the phage's lytic activity against resistant strains of Salmonella.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121299519","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 spite of the recent advancement in cancer therapies, the clinical follow-up still lags far behind.Recent studies show that, stem cells are bestowed with distinctive functions, like tumor cells relocation, immunosuppression and production of bioactive elements, that helps in cancer targeting that bypassobstacles.Recent understanding show that Preclinical stem cell-based strategies has proved potential for targeted anti-tumor therapy applications. Stem cell applications in modulation and remodeling of immune system happens to be frequent procedure used past ten years in successfully treating tumor.Generation of human somatic cells into induced pluripotent stem cells (iPSCs) has often been a time consuming laborious intensive and expensive process. Additionally, the major problem with iPSCs is their tendency to revert to original somatic state. Hence, a robust computational model in discovering genes/molecules necessary for iPSC generation and maintenance can be a major leap towards in stem cell research.The synergistic combination of genetic relationship data, advanced computing hardware and nonlinear algorithms and could make artificially-induced pluripotent stem cells (aiPSC) a near future reality. Genes or proteins that are known to be essential in human pluripotent stem cells (hPSC) could possibly be used for system modelling. The present investigation is aimed to develop an unsupervised deep machine learning technology for the prediction of genes relevant in aiPSC production and its maintenance for both common and rare diseases making it a cost-effective approach.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128742333","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}
