In Ecuadorian Amazon, Bothrops atrox is the main snake associated with ophidic accidents. 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
在厄瓜多尔的亚马逊地区,Bothrops atrox是与毒蛇事故有关的主要蛇。唯一被批准的治疗蛇咬伤的方法是抗蛇毒血清,其有效性取决于生产中使用的参考毒液。值得一提的是,atrox是一个地理分布广泛的物种,不同种群之间毒液的组成和表型可能存在差异。这种可变性可能是同一物种种群中蛇咬伤的毒理学效应变化的原因。考虑到这一点,本研究分析了来自两个亚马逊地区的个体的两种毒液样本。根据结果,确定了两种毒液之间毒素主要家族的丰度及其活性的差异

To evaluate the chemical composition of the taro tuber ( Colocasia esculenta (L) Schott) of waste with and without processing for use in pig diets. In samples of natural tubers, solid state fermentation (SEF) and flour, it was determined: dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), ash, extract ethereal (EE), nitrogen-free extracts (NFE), gross energy (GE), digestible energy (DE) and metabolizable energy (ME). The experiment was conducted according to a completely randomized design, in the necessary cases the means were contrasted with the Duncan test with (p<0.05). The major (p<0.05) content in DM presented the flour. In relation to the OM, the highest contents were evidenced in the natural tuber and in flour. As for CP and ashes, the SEF had the best (p<0.05) contents. As for the CF and NFE, there were no differences (p>0.05) between the unprocessed and processed tuber. Regarding EE, GE, DE and ME, the natural tuber had the highest (p<0.05) concentrations, respectively. In conclusion, processed waste taro tubers constitute a good source of nutrients, guaranteeing a local alternative food of adequate nutritional characteristics for use in pigs.

Steroidal saponins isolation of Agave americana subsp. andina by enzymatic hydrolysis: a new approach. 美洲龙舌兰亚种甾体皂苷的分离。酶法水解地黄:一种新方法。
C. Lozano
. 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.
. 目前,甾体皂苷(SE)的研究还不存在于厄瓜多尔,这是一个科学投资较少的国家;尽管拥有未开发的特有植物,如美洲龙舌兰。安迪娜(或著名的“蓝色铅笔”);它是植物化学和生物技术研究的重要物种。另一方面,自20世纪末以来,中国一直是SE的主要生产国,并且在前药方面取得了进展。出于这个原因,这篇短文的作者解释了厄瓜多尔生物技术人员如何用一种新的酶水解方法进行实验设计。这种创新的方法使用马铃薯葡萄糖减法,这是一种培养查瓜米什基酵母的培养基。该方法可用于提取o -糖苷酶。这些分子是龙舌兰属植物的活性物质。最后,本研究的重要性并不在于SE对药物的优势或其对人体的影响;实际上,主要的好处是通过对科学研究的投资,通过大规模生产来增强厄瓜多尔的制药业。

In vitro CRISPR-mediated gamma globin gene activation in HEK293 体外crispr介导的γ -珠蛋白基因在HEK293中的激活
Ana Claudia Samaniego Villacis, Mauro Berta Ramasko, Laura Richmond, A. West
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.

Bacteriophages as an alternative to the use of antibiotics in poultry breeding 在家禽养殖中,噬菌体作为抗生素的替代品
T. Guerrero, S. Zapata
. 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.
. 摘要细菌对抗生素的耐药性是一个全球性的新问题;畜牧业中使用的抗菌剂是导致耐药基因繁殖的最重要因素,因为畜牧业中抗生素的使用量大于医疗领域。由于噬菌体是控制食品中人类致病菌的一种安全选择,本项目旨在分离和表征沙门氏菌噬菌体,并在不使用抗生素的情况下,利用它们在农场水平上减少家禽中这种病原体的存在。我们获得的噬菌体鸡尾酒在体外对从家禽养殖场分离的83%的沙门氏菌株具有裂解活性。抗沙门氏菌活性最强的鸡尾酒来自附近受污染的河流。我们能够在屠宰前48小时将噬菌体应用于鸡肠中消除病原体,但有必要对噬菌体对耐药沙门氏菌菌株的裂解活性进行永久监测。

A Machine learning approach for the prediction of efficient iPSC modeling 一种高效iPSC建模预测的机器学习方法
Anuraj Nayarisseri, Ravina Khandelwal
Cancer stands as major cause of mortality in the world, and it's the morbidity has significantly increased in both developing and developed nations. 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.
癌症是世界上导致死亡的主要原因,其发病率在发展中国家和发达国家都有显著上升。尽管近年来在癌症治疗方面取得了进展,但临床随访仍然远远落后。最近的研究表明,干细胞具有独特的功能,如肿瘤细胞的重新定位、免疫抑制和生物活性元素的产生,有助于绕过肿瘤障碍靶向癌症。最近的研究表明,临床前干细胞为基础的策略已被证明具有靶向抗肿瘤治疗应用的潜力。干细胞在免疫系统调节和重塑中的应用是近十年来成功治疗肿瘤的常用方法。将人体细胞转化为诱导多能干细胞(iPSCs)是一个耗时、费力和昂贵的过程。此外,诱导多能干细胞的主要问题是它们倾向于恢复到原来的体细胞状态。因此,在发现iPSC生成和维持所需的基因/分子方面,一个强大的计算模型可能是干细胞研究的一个重大飞跃。遗传关系数据、先进的计算硬件和非线性算法的协同结合可能使人工诱导多能干细胞(aiPSC)在不久的将来成为现实。已知在人类多能干细胞(hPSC)中必不可少的基因或蛋白质可能用于系统建模。本研究旨在开发一种无监督深度机器学习技术,用于预测与aiPSC产生相关的基因及其对常见和罕见疾病的维持,使其成为一种具有成本效益的方法。

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.

Obtaining a computer-assisted QSAR model for the prediction of anti-inflammatory activity 获得计算机辅助的QSAR模型用于预测抗炎活性

The main objective of this study was to develop quantitative structure-activity relationships (QSAR) for the classification and prediction of anti-inflammatory activity. To this end, the ToSS-MoDE approximation was applied for the calculation of the spectral moments of the adjacency matrix between edges of the molecular graph with suppressed hydrogens, weighted on the main diagonal with moments of bond dipoles, bond distance, Van der Waals radius, polarizability and hydrophobicity to 509 active and inactive compounds. The calculated descriptors were used in the design of a training series and a prediction series. With the training series, a discriminant function was developed for the anti-inflammatory activity and another function to characterize the potential of these drugs using the Multivariate Linear Discriminant analysis, obtaining a good total classification of 96.07%. The model was validated by using the external prediction series, obtaining a good classification of 92.59%.
本研究的主要目的是建立定量构效关系(QSAR),用于抗炎活性的分类和预测。为此,应用tos - mode近似计算了含有抑制氢的分子图边缘之间邻接矩阵的谱矩,并在主对角线上加权了509个活性和非活性化合物的键偶极矩、键距离、范德华半径、极化率和疏水性矩。计算得到的描述符用于训练序列和预测序列的设计。利用训练序列建立了抗炎活性判别函数,并利用多元线性判别分析建立了表征药物潜力的判别函数,总分类率为96.07%。利用外部预测序列对模型进行了验证,分类率为92.59%。
