[quick news] on September 25, 2018, a small electrode made paralyzed patients stand again

We all know that when the neural network is damaged, it is difficult to recover from paralysis Recently, doctors at the Mayo Clinic in the United States implanted electrodes in the injured spinal region of paralyzed patients, so that the neurons in their legs can connect to their brain, and regain voluntary control over the movement of their legs The electrodes are placed under the injured area and connected to a pacemaker sized battery that is also placed in the patient's stomach Use the remote control to turn the system on and off, accurately stimulate the position, and let the patient stand or walk again This breakthrough will help millions of people get rid of wheelchairs and get rid of paralysis by training their bodies Https://www.dailymail.co.uk/health/article-6201773/a-man-paralysed-wait-walking-world-implant-fitted-spine.html Japanese researchers have used iPS cells to culture cells that can differentiate into eggs, researchers at Kyoto University in Japan announced recently that they use human induced pluripotent stem cells (IPS For the first time, the oocytes which can differentiate into eggs were successfully cultured This research result is expected to be used to study the causes of infertility and some genetic diseases Previously, researchers at Kyoto University have successfully cultured primordial germ cells from human iPS cells Primordial germ cells are the early cells that produce male and female germ cells After being approved by the ethics committee of Kyoto University, researchers of Kyoto University first cultured primordial germ cells from human iPS cells, and then cultured them together with a large number of ovarian cells extracted from experimental mouse embryos, and finally obtained oocytes The researchers said that cultured oocytes could be used to study the causes of infertility and some genetic diseases Http://news.scienceet.cn/sbhtmlnews/2018/9/339405.shtm Chinese scientists have made an important breakthrough in the field of enhanced microbial electrocatalysis efficiency in synthetic biology Professor Song Hao's team of Tianjin University published the title of "modulerengineering to increase intracellular NAD (H / +) promotions rate of online in nature communications In this paper, it is clarified that the capacity of intracellular electron pool is a major scientific problem in the field of microbial electrophysiology, which limits the rate of extracellular electron transfer It provides a new way for engineering electric energy cells to improve the efficiency of electron transfer Professor Song Hao's team adopted the modular synthetic biology strategy to optimize and reconstruct the NAD + ab initio synthesis path, remediation synthesis path and general synthesis path of Schwarzschild's bacteria By increasing the total amount of NAD (H / +) as an intracellular electron carrier, it enhanced the substrate consumption rate, significantly promoted the extracellular electron transfer rate, and systematically clarified the intracellular electron pool of electric energy cells Whether the capacity of NAD (H / +) is large enough and whether the intracellular electron pool limits the rate of extracellular electron transfer are two important scientific issues in the field of microbial electrophysiology Https://www.nature.com/articles/s41467-018-05995-8 FDA grants non opioid pain treatment drug ca-008 breakthrough therapy qualification pmlive recently reported that as part of the fight against the prevalence of opioid addiction, FDA gives priority to the review of new non opioid pain drugs The FDA of the United States has awarded the qualification of breakthrough therapy ca-008, a drug under development by central analgesics, which is intended for postoperative pain Concentric specializes in new non opioid pain therapies Ca-008 is a pioneering non opioid drug that can be rapidly converted into capsaicin, which is a powerful TRPV1 agonist Ca-008 provides long-term pain relief by selectively dulling pain conducting nerve fibers after a single local injection, without numbness or weakness, the company said Http://www.organichem.com/show.asp? Id = 56922 bone stem cells have been found in human body for the first time in ten years Scientists have been looking for a kind of human stem cells that can reliably develop into bones, cartilage, etc Now, American scientists have finally found the bone stem cells in the human body The research shows that these stem cells can be induced by the discarded fat after liposuction, which shows that they are rich in resources, which lays a foundation for future research and treatment of fracture and osteoporosis Moreover, the researchers isolated stromal cells from liposuction fat and cultured them with bone growth factor protein in a dish, creating bone stem cells as well "Every year half a million Americans suck their fat out and discard it as medical waste, which is the material we can use to make bone stem cells," longgak said http://blogs.discovermagazine.com/d-brief/2018/09/21/human-skeletal-stem-cells-discovered-real-life-skele-grow/#.W6majvm-uUk
