25.05.2009The quality of medical examinations conducted at a distance with the help of modern means of communication is not much inferior to real visits of doctors.
18.05.2009The tendency to form tumors is a serious problem on the way to the use of embryonic stem cells for the treatment of a variety of diseases and injuries. Malignancy of embryonic stem cells can be avoided if bone marrow stem cells are transplanted at the same time.
18.05.2009The adult body's own stem cells are not enough to restore the myocardium after a heart attack. Cell therapy has been successfully used to prevent and eliminate damage to the heart muscle after a heart attack, but has not yet been used as a preventive measure, and not just before a heart attack, but even before the birth of a potential patient.
18.05.2009Further tests allowed to improve the invention, its interactive gaming table and information display, as well as to form a set of 20 computer games that train and regulate the most important mental skills, stimulate social perception. These games, among other things, are fascinating in themselves.
18.05.2009A group of scientists from the University of Manchester (England) managed to synthesize a ribonucleotide (a compound necessary for the formation of RNA) in external conditions comparable to the conditions of the primitive Earth, and on the basis of molecules that were most likely in the primary broth.
15.05.2009According to the plaintiffs, patents for research on various genes restrict the civil liberties of patients, allow patent-holders to set an inflated cost of genetic tests, and also deprive other organizations of the opportunity to study these genes.
15.05.2009In response to damage to the vessel wall, smooth muscle cells move from a state of "resting phenotype", in which they are only able to contract, to a state of "synthesis phenotype", when they begin to proliferate. The FHL2 protein synthesized by heart cells suppresses the activity of genes necessary for the preservation of smooth muscle cells of blood vessels in a state of "rest".
14.05.2009The researchers connected fluorescent dye, RNA fragments and peptide fragments to iron oxide nanoparticles. The task of peptides is to identify tumor cells, RNA fragments suppress the work of a number of genes characteristic of cancer cells, killing them. Magnetic iron oxide nanoparticles play the role of contrast for MRI, and fluorescent dye allows you to observe cancer cells using microscopy.
14.05.2009Each of the detected genetic differences is very common in the world, but causes minor fluctuations in pressure. It is the combination of several genes that leads to the development of hypertension.
13.05.2009For the third time together for the sake of life, participants of the march "Together against Breast Cancer" will walk through the streets of the capital of Russia. The action under the motto "Together for life" starts at noon on May 30 at Vasilyevsky Descent and finishes in "Luzhniki", where the concert "Rock against Cancer" will take place.
13.05.2009On May 18, 2009, the Melanoma Diagnosis Day will be held in Russia for the 3rd time. Residents of the 27 largest cities of the Russian Federation will be able to get free consultation and undergo examination of pigmented formations on the skin.
13.05.2009The US healthcare system has saved almost three quarters of a trillion dollars on generics over the past ten years.
12.05.2009Unlike higher plants, moss easily produces proteins encoded by human and mammalian DNA. Thus, moss, which needs only water, light and mineral salts to produce a given protein, has excellent prospects as a cheap and simple bioreactor.
12.05.2009A good substitute for a low-calorie diet has been found, contributing to an increase in life expectancy in the simplest organisms. Yeast cells grown on a glycerin diet live twice as long as yeast grown in a conventional low-calorie environment. In addition, such yeast is more resistant to damaging environmental factors.
12.05.2009Researchers from the Hebrew University in Jerusalem have proposed a method to reduce the risk of developing tumors using embryonic stem cells – suppressing the synthesis of a protein called survivin.
07.05.2009New York researchers have identified three genes that specifically regulate the spread of breast cancer metastases to the brain. The data obtained are important for understanding the mechanisms of metastasis spread and developing possible approaches to cancer treatment, especially gene therapy methods.
07.05.2009The European Parliament overwhelmingly rejected a proposal to impose restrictions on scientific experiments on animals.
07.05.2009Scientists from the University of Massachusetts have developed a new – oral – method of targeted delivery of small interfering RNAs (miRNAs). The method was tested on mice and showed excellent results in suppressing the inflammatory process, similar to what develops in humans with a number of diseases.
07.05.2009A solemn ceremony of awarding the winners of the III All-Russian Internet Olympiad "Nanotechnology – a breakthrough into the future" took place.
