Verb Surgical company has been quietly planning to develop a new generation of surgical robots, since March collaboration with Johnson & Johnson, which is only part of the details of the cooperation, but now, a scientist Babak Parviz before Google's ongoing development of new technologies, and It provides a rare opportunity for the company's most innovative process. 2010, Babak Parviz worked at Amazon company, Amazon has joined the Alphabet of Google X department for the development of Google glasses wearable computer, but it also put forward some ideas developed for the operating room of the robot, which one Plan is to create autonomous surgical robot to perform surgical procedures through the joystick, while assisting surgeons completed surgical procedure.
Parviz told Medium site, we rely on the surgeon's dexterity, but now we know that manual operation more accurate than the machine, and the use of the machine may be able to provide adequate opportunity for the surgeon to perform the surgery, but no longer like before use hands to complete the surgical procedure. Robot surgery can help for quick surgical procedure, and produces a more rapid response time, traditional surgical fundamentally limited by the human decision-making time, but also limited the duration of treatment of human operation of the instrument, while surgical robot You can solve many problems, it can more quickly help repair vascular and other surgical operations.
At present this technology to developing countries have a greater value, Verb companies seem to see the researcher Babak Parviz early ideas, the company recently said that their aim is to develop a comprehensive surgical solution to platform or frontier The robots ability and first-class medical device technology integration in the laboratory. Global Chairman of Johnson & Johnson medical device company Gary Pruden said in a statement that, we believe, Verb Surgical Company has the potential to change the future of surgery, and not just robotic surgery, the research team is currently in the development of robotic platform has been made substantive progress.
Involved in the field of robotics surgery can help Verily small fortune in the growing market, as of 2021 surgical robotics market will increase to $ 20 billion, other companies, such as Intuitive Surgical and Stryker companies currently in this area also We have made tremendous progress. Verb future in the field of surgical robotics technology still has a long way to go, I believe that in the near future, our surgeons can make timely decisions, but surgical robot to operate according to the surgeon's decision.

Imidafenacin for sale
Product name:Imidafenacin
CAS:170105-16-5
Molecular Formula:C20H21N3O
Formula Weight:319.4g/mol
Description:Imidafenacin is an antimuscarinic that is used in the treatment of urinary frequency, urgency, and incontinence.It is an antagonist for the muscarinic acetylcholine (ACh) receptor currently under development for the treatment of overactive bladder. Affinities of imidafenacin and other drugs for muscarinic ACh receptor subtypes were investigated by examining inhibitory effects on ACh release in the rat urinary bladder and K+ efflux in the rat salivary gland in functional and binding assays

Stem cells developed can produce serotonin neurons
Researchers from the University of Wisconsin by the research and development of a way to manufacture serotonin special nerve cells, serotonin plays an important role in a variety of chemicals in the brain, which can affect the body's mood, sleep, anxiety, depression , loss of appetite and other symptoms, but also a lot of serious mental disorders who plays an important role, such as schizophrenia and bipolar disorders.
Researcher Su-Chun Zhang said, from the essence, serotonin can regulate many aspects of the body's brain function, including exercise, this chemical substance is located in back of the head by a series of special structure of neurons generated, and serotonin may play a role because of its influence manufacture serotonin neurons can have an impact on almost every part of the brain.
Research published in the international journal Nature Biotechnology, the researchers began the two types of stem cell research, one of which comes from the embryo, another from adult cells, because serotonin neurons can be generated before birth, so researchers must create a suitable chemical environment fetal development in the womb; they said, it sounds quite simple, but we need to make to produce many different types of nerve cells, for which it is necessary to guide stem cells to make it develop into a special form, followed by the use of a specially designed molecular sequences studied at the specified concentration.
While other scientists can make adult stem cells into becoming similar to serotonin neurons cells, the researchers used previous research in pluripotent stem cells produce serotonin neurons in a small part, but it is difficult to study these cells, if it is detected to 10 neurons, which have only two serotonin neurons, but the researchers can not barely detectable release of serotonin.
In order to confirm that these new cells could play a similar function of serotonin neurons, the researchers will be able to reveal react to certain FDA approved drugs neurons, these FDA approved drugs can be adjusted by depression and anxiety serotonin pathways happen; Previously researchers tried to use the mouse model study, this paper they use other growth factors were related research.
Although the cells derived from stem cells can be used to detect drug toxicity, and researchers to target higher serotonin neurons, they believe that the current research could help develop new drugs more effective, especially with high levels of neuronal function related to effective drug. This particular nerve cells from human organism, which can be very beneficial for patients suffering from depression, bipolar disorder and anxiety.
Because neurons from induced pluripotent stem cells, this study find relevant therapy for the treatment of mental illness provides a new way of thinking, but also for the post-researchers try to develop new personalized treatment provided some ideas.
