RESUMEN
Under the background of " Internet+ medical treatment" and the continuous deepening of face recognition technology research, the face recognition industry has continued to mature, and face recognition has been initially applied in medical fields such as hospital management, auxiliary medical care, and epidemic prevention and control. At the same time, face recognition technology brings problems including error risk, technical cracking risk, privacy risk, equality risk, abuse risk, and other issues in practice, which seriously threaten the personal and property rights and interests of the public. On the basis of summarizing the specific application direction of face recognition technology in hospitals, the authors sorted out the legal regulation of face recognition in China, and proposed that it should be based on technology research and development, strengthen the " gatekeeper" responsibility of medical institutions, improve legal system and recommendations for strengthening judicial leadership in order to improve the legal regulations of face recognition technology, reduce the risk of infringement by medical institutions in the application of face recognition technology, and protect the legitimate rights and interests of citizens.
RESUMEN
Explainable artificial intelligence (AI) promotes the development of medicine and raises different ethical challenges. This new challenge is manifested in two aspects, including pre-interpretation and post-interpretation. The technical root of the ethical issues leading to the medical application of explainable AI is the negative effects of explainable technology, the social root is the lack of relevant moral principles and legislation, and the root of subjectivity lies in the diversity of interests of various stakeholders. Therefore, the solutions to the problem are to strengthen technological innovation, explainable AI medical application ethics education, training of medical staff and interdisciplinary cooperation, improve relevant moral principles, laws and regulations, and realize personalized interactive interpretation.
RESUMEN
Xanthine oxidase (XO) is an important enzyme with broad medical applications as detecting reagent in many diagnostic kits. In this study, buffalo liver xanthine oxidase (BLXO) was purified to homogeneity by acetone precipitation and chromatography on DEAE-cellulose and Sephacryl S-300 columns with a specific activity of 7.2 units / mg protein which represent 31.3 folds. The native molecular weight of the purified enzyme is 200 kDa and its subunit molecular weight was determined by SDS-PAGE to be 67 kDa. The isoelectric point (pI) value of BLXO isoenzyme is at pH 6.0 – 6.2. It displayed its pH optima at 7.6 and the Km value is 1.1 mM xanthine. FeCl2 increased the activity of BLXO while CuCl2, MnCl2 and ZnCl2 were found to be inhibitors of the purified enzyme. Allopurinol inhibits BLXO competitively and has one binding site on it with Ki value of 0.025mM. Abbreviations: BSA, Bovine serum albumin, XO, Xanthine oxidase, NBT, Nitroblue tetrazolium, PAGE, Polyacrylamide gel electrophoresis, PMS, Phenazine methosulphate, BLXO, Buffalo liver xanthine oxidase
RESUMEN
Aims: The objective of this research is to extract the aorta and to measure its diameter for preoperative planning of heart surgeries such as Endo Vascular Aortic Repair (EVAR) or Aortic Valvular Replacement (AVR). Study Design: Experimental Study. Place and Duration of Study: Department of Knowledge Engineering and Graduate School of Engineering in Tokyo City University, and Department of Cardiovascular Surgery in Sakakibara Heart Institute, between April 2009 and August 2012. Methodology: In order to extract the aorta correctly, the spine is removed first. Then, the diameter of the aorta is measured by considering the curvature of the aorta, especially the aortic arch. The novelty of the proposed method is as follows. 1) The spine that is almost parallel to the aorta is extracted and removed before the aorta extraction. 2) The aorta is traced by interpolating the image between the Computer Tomography (CT) sliced data to compensate the insufficient axial resolution. 3) The diameter of the aorta is measured by considering some planes, one of which is perpendicular to the center line of the aorta to lower the error due to the curvature. Results: The spine has been extracted and removed correctly and also the aorta has been extracted with the proposed method even if there is an aneurysm in the aorta. In addition, the diameter measured automatically is almost the same as that measured manually. Conclusion: It has become possible to extract the aorta even if the spine overlaps with the aorta. In addition, the measured diameter of the aorta ranges from 20 to 30 [mm], which is almost the same as the average of normal persons’ aorta. However, some parts of the heart were extracted as the aorta, and the diameter of the aortic arch was not correct. These are the issues for future works.

El presente artículo presenta una revisión bibliográfica sobre el diseño de exoesqueletos y las diferentes aplicaciones que estos pueden tener en la vida humana. Se exponen diferentes desarrollos, resaltando las partes más importantes de cada uno y prestando especial atención al área de la ingeniería electrónica presente en estas estructuras. Además, se realiza un agrupamiento de los diseños, dependiendo de la zona corporal para la cual se ha construido el exoesqueleto o de la finalidad del estudio realizado. Finalmente, se presentan desarrollos y estudios que buscan utilizar las señales mioeléctricas como parte fundamental del sistema exoesquelético.
This paper presents a literature review about exoskeletons and their applications in human life. Different developments highlighting the most important parts of each of them, and paying particular attention to the area of electronic engineering related to these structures, are shown. Also, a grouping of the different kinds of structures is made depending on the area of the human body to which the exoskeleton was intended to or depending on the purpose of the research. Finally, various studies and developments which use mioelectric signals as a fundamental part of the system are presented.
