The objective of this article is to present the results that can be obtained by performing brain mapping from the Emotiv EPOC + brain computer interface in conjunction with the Emotiv 3D Brain Activity Map tool. The methodology is composed of: materials used, application of tests and analysis of results. The application of tests includes the assembly and connection of the equipment, relaxation tests and physical movement tests to visualize the activation of the different areas of the brain. Likewise, the graphical interface of the program, the visualization tools and information analysis, which it provides, is presented. The results present the brain mappings obtained through the software and an analysis of the information obtained. The contribution of this applied research is to evaluate the tools that this type of commercial technology is able to provide for the incorporation of brain activity in engineering areas such as robotic rehabilitation instead of using specialized equipment that is not commonly operable by any researcher and that It can make research more expensive.

The study of the biological tissue varies its behavior, in function of the frequency to which it is subjected. The functions of Cole-Cole, Debye and Lorentz are considered the most used to study the parameters of conductivity and permittivity of biological tissue such as: liver, stomach, gray matter, pancreas, blood, breast tissue to name a few. Depending on the frequency, there may be three different relaxation times. These depend on the nature and physical characteristics of the tissue and its effect in the presence of an electromagnetic signal. The Cole-Cole function is most appropriate when considering a study in the frequency domain, and the Debye function is established to perform the study in the time domain. It is of particular interest to make a comparison between the methods of Cole-Cole and Debye, to define the advantages and disadvantages of each of them. The Lorentz function is used for frequencies of the Tera-Hertz order. Comparative graphs are obtained between both for the biological tissues mentioned above. For each of them the electrical parameters are calculated in a frequency range between 100 Hz and 10 GHz.

The need for prosthesis development dates back many years, but only in the last few years has material, control and automation technology been available to obtain prostheses that imitate the function and performance of the real part that is replaced. The development of prosthesis, involves the need to merge knowledge of human physiology and biomechanics, machining of materials. Currently there are various types of prostheses that are adapted to the needs of people who require them. Recent advances in bionics have made possible the development of more efficient prostheses, but at a high cost. There are limitations and challenges to be overcome in order to be successful, in addition to being accessible, for people with low resources, who only want to be able to walk and be independent, for which purpose it is intended to design and manufacture a prosthesis that supports walking to a person, with a low cost and that the people of low resources can acquire i.

Goals. To analyze the effect on the production of acetogenins of Annona muricata cultivated in vitro by means of Temporary Immersion Bioreactors (BITs) promoted by the use of exogenous inducers proposed from a bioinformatic analysis. Methodology. A bioinformatic analysis was carried out at the KEGG site of the metabolic pathways of polyketide synthetase (PKS) and fatty acid synthetase (FAS) plants from which acetogenins are derived. Five treatments were performed in the BITs with soursop explants; 1) BAP, 2) BAP + AAs 3) BAP + AAs + Putrescine, 4) BAP + IAA and 5) BAP + IAA + Citrate. BAP and IAA are plant hormones, AAs is a mixture of three ketogenic amino acids, Putrescine and Citrate are inducers of PKS and FAS. Contribution. The cultivation of soursop explants was monitored using BITs of the 5 treatments for 8 weeks without apparent contamination. Sprout observation started from week 6 in treatment 1 and 2 but not in 3 over 8 weeks, with putrescine being more than an inducer a stress factor for the explant as they became necrotic. Treatments 4 and 5 were only monitored until the third week and no information on sprouting was collected. Differences in the profile of acetogenins by HPLC-PDA were observed between soursop leaves to ex vitro and in vitro and between treatments 1, 2 and 3.

Arsenic and fluorine occur naturally in groundwater, especially in desert and semi-desert areas. Chronic exposure through drinking water to these substances causes adverse health effect, which are limited in water intended for human consumption. Objective: This work was carried out with the aim of improving the quality of water from wells with high contents of arsenic and fluorine, achieving compliance with the limits established in the Mexican regulations for drinking water. Methodology: A system of two-panel solar distillation was used for treatment of water from three wells characterized by high levels of arsenic and fluoride, which are intended for human consumption. Contribution: The solar distillation system used improved the quality of the groundwater through the removal of arsenic (99%), fluoride (96%) and dissolved solids (98%). The proven system is a viable alternative for water treatment in small communities that do not have access to demineralization water plants that operate with high costs, thus eliminating health risks associated to the chronic intake of these elements.

The general objective of this project was to measure the biogas produced by anaerobic digestion from two prototypes of biodigesters, supplied with organic waste and pig manure, at the Technological University of Cancun, to see what type of waste is most optimal in production of biogas. For the measurement of biogas, first the two biodigesters were built and in each one a pressure gauge was installed to measure the gas pressure generated in each container, in the same way bicycle chambers were installed to store the biogas obtained and observe what waste it produces plus. It was observed that the biodigester with pig manure provided 11.3 psi and the biodigester loaded with organic waste produced 8.5 psi of biogas. Therefore, it is appreciated that pig manure has a faster process in the generation of biogas, than other waste, however both are recommended for the generation of biogas.

The available resources during plant development, sometimes plant can be limited due to energy used during physiological plant defense to pathogens attacks. The main of this work was the physiological analysis of Zea mays plants development under different sustainable fertilization systems, as the earthworm-humus, and their relation with the response to Ustilago maydis infection, a biotrophyc fungus that causes the disease known as common coal or cuitlacoche in corn. Mize seedlings developed with different % of humus/soil under greenhouse conditions were inoculated with U. maydis (T1), and plants not inoculated as control (T0). Physiological and growth measurements in T1 showed a significant effect on the plant, the best was a 25%. After infection, the plants growth was lower as a result in decrease in photosynthesis activity, however, the presence of humus partially counteracts the fungus infection. High concentrations of humus reflected a negative effect on plant growth. In the future, the studies in the field will serve to deduce the importance of these agricultural practices in plant-fungus responses.

Currently, cancer is one of the leading causes of death worldwide. The latest reports from the World Health Organization (WHO) of 2018 show alarming figures that indicate 18.1 million new cases and recorded 9.6 million deaths from cancer, with a 5-year prevalence of 43.8 million patients. The low efficiency of conventional cancer treatments has generated scientific research focused on identifying new products with specificity to efficiently treat this disease. Various bacterial metabolites such as parasporins (PS), cytotoxic proteins of Bacillus thuringiensis (Bt), have been successfully applied against different cancer cell lines in the past 19 years. Therefore, it is important in this work to contextualize cancer as a global health problem, and briefly mention the conventional treatments used. The most relevant investigations to isolate Bt strains producing PS are described, as well as the classification, production and purification of these metabolites. Finally, the nature of the high cytotoxicity of the 19 PS reported to date is mentioned, emphasizing the feasibility of its application as an alternative high-cytotoxicity cancer therapy, and with great potential to treat various types of cancer.

The latest reports from the World Health Organization (WHO) of 2018 show alarming figures that indicate 18.1 million new cases and recorded 9.6 million deaths from cancer, with a 5-year prevalence of 43.8 million patients. The low efficiency of conventional cancer treatments has generated scientific research focused on identifying new products with specificity to efficiently treat this disease. Various bacterial metabolites such as parasporins (PS), cytotoxic proteins of Bacillus thuringiensis (Bt), have been successfully applied against different cancer cell lines in the past 19 years. Therefore, it is important in this work to contextualize cancer as a global health problem, and briefly mention the conventional treatments used. The most relevant investigations to isolate Bt strains producing PS are described, as well as the classification, production and purification of these metabolites. Finally, the nature of the high cytotoxicity of the 19 PS reported to date is mentioned, emphasizing the feasibility of its application as an alternative high-cytotoxicity cancer therapy, and with great potential to treat various types of cancer.","PeriodicalId":264276,"journal":{"name":"Revista de Ingeniería Biomédica y Biotecnología","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125448456","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}
