Catch-up growth after insults to growing organs is paramount to achieving robust body proportions. In fly larvae, injury to individual tissues is followed by local and systemic compensatory mechanisms that allow the damaged tissue to regain normal proportions with other tissues. In vertebrates, local catch-up growth has been described after transient reduction of bone growth, but the underlying cellular responses are controversial. The international team of scientists from the Sloan-Kettering Institute in collaboration with the Monash University has been studied catch-up growth in foetal mice and made the discovery that can help to create the therapy for people with growth disorders.
The new test for the Ebola virus was developed by researchers at the Wyss Institute for Biological Engineering at Harvard University, USA. Scientists, working in the field of synthetic biology, combining biology, engineering and informatics together to observe, understand and copy the principles of biological life, to create new medical technologies and medicines. Scientists are aimed at creating a cheap, simple and reliable test for the Ebola virus. This test will be something like an ordinary paper strip, on which it is enough to put a drop of blood or saliva of a sick person. In the first study, researchers created pocket test strips equipped with synthetic gene networks.
The sensor for the diagnosis of prostate cancer by urine was developed by scientists from the University of Liverpool and the University of the West of England. Prostate cancer is one of the most common oncological diseases among men. The success of its treatment depends heavily on the stage at which it was diagnosed. And this is the main problem because men do not like to see a doctor until the disease crosses the line when it becomes very important for life. Unfortunately, then it may be too late. The development of simple methods for diagnosing cancer will greatly help to solve this problem. The main aim of scientists is to create a test that avoids procedure of detecting cancer in a non-invasive way by smelling the disease in men’s urine.
The new way of charging the implant was developed by scientists from the California Institute of Technology. One of the main problems of implants, which prevents their wide distribution, is the need to periodically change the battery. This is especially difficult if such a device is placed in the patient's head, like a cochlear implant to improve hearing. Therefore, any solution that allows the use of implants without the need to replace the battery, always with interest meets in the medical community. Hyuck Choo of the California Institute of Technology and his colleagues plan to scavenge the necessary energy from the vibrations of the vocal cords that occur when someone is talking. Dr. Choo’s power plants are small sheets of lead zirconate titanate, a substance that is piezoelectric—meaning it generates electricity when it vibrates. He knew from past work that sheets of the size he chose (just under 1cm2) resonate at around 690Hz. This is close to the F in the octave above middle C.
The technology that protects cells from aging has been developed by researchers from Stanford University and the VA Palo Alto Healthcare System (VAPAHCS). Aging is the process of gradual disruption and loss of important functions of the body or its parts, in particular, the ability to reproduce and regenerate. As a result of aging, the body becomes less adapted to environmental conditions, reduces and loses its ability to fight bacterias and resist illnesses and injuries. Typically, this process begins with a deterioration in the depth of each cell. However, scientists have found a way to prevent this process, they have identified a protein that protects cells from problems associated with aging, especially protecting a vulnerable set of genes.
The artificial skin, made from spider silk, was developed by German scientists from Medical School Hannover. The human skin is an extremely necessary donor material, this technology can make life easier for many people. Usually, skin transplantation is required after extensive burns or with the development of pressure sores. The last type of skin lesion occurs in bedridden patients who are unable to independently change the position of the body, as a result of which the skin literally 'settles down', while the nerve endings and blood vessels die. Skin grafts are vital for treating burn victims and other patients. To restore the skin today, it takes a large transplant or expensive treatment, which even in the US costs more than $ 40,000. However, the new method of creating a skin will not only solve the problem with donors but also significantly reduce the cost of treating patients with skin damage.
