Nanoantibodies – "magic bullets" of Russian production

The result of the work were two patented nanoantibodies. We continue to work — we want to further increase the activity of the obtained nanoantibodies: we optimize their structure, try to obtain their derivatives, try to improve the binding properties and effectiveness of action. We hope to approach and maybe surpass Avastin in terms of efficiency.

Nanotechnology in medicine and pharmacy

The development of nanomedicine is closely connected with the revolutionary achievements of genomics and proteomics, which allowed scientists to get closer to understanding the molecular foundations of diseases. There are 5 main areas of application of nanotechnology in medicine: delivery of active drugs, new methods and means of treatment at the nanometer level, in vivo diagnostics, in vitro diagnostics, medical implants.

Sow wisely!

To create ideal conditions that ensure almost the same size of microbial colonies (the relative standard error is about 1%) or Poisson distribution for their number, a special "ordered seeding" technique and a "poissoner" device were invented. They are most popular with molecular geneticists who need accurate estimates of mutation rates, recombination, transformation, survival, etc.

Male contraception: it is necessary to relax the tail

The CATSPER1 protein is part of the ion channel that launches calcium ions into the cell. As a result, the tail of the sperm begins to beat with increased energy. In the absence of this protein, the sperm simply does not have the strength, speed and mobility to fertilize an egg. Smith and his colleagues propose to cause the same condition artificially by blocking calcium channels with the help of medications.

Automation of science: a robot laboratory assistant and a robot scientist

Time will tell what these two works will mean for humanity. Enthusiasts of artificial intelligence can say that scientists have shown its ability to compare with the intelligence of humans. Anthropocentrists will object that we are talking only about special cases and it is premature to put an equal sign.

Pay (in an envelope or as a gift) for free healthcare!

The corporate norms existing among doctors, as before, support the practice of informal payment. Payment in the form of gratitude, made on the initiative of the patients themselves, is recognized by the overwhelming majority of doctors as a fully justified material compensation for the labor they spend. Extortion of money from patients, that is, receiving payment at the insistence of a doctor, is almost universally condemned.

"Ions of Skulachev" against senile eye diseases

The list of senile eye diseases includes glaucoma, macular degeneration, various forms of retinopathy, cataracts, age–related hyperopia. Science knows that one of the reasons for such disorders is the accumulation of oxygen free radicals in the body. By neutralizing reactive oxygen species in the mitochondria of eye tissues, "Skulachev ions" restore vision.

A gene has been found that increases penis size and male potency

After analyzing the DNA of more than 1,000 inhabitants of Iceland, experts from the biotech company deCODER claim that they were the first to isolate a single gene responsible for male potency and penis size in the inhabitants of the country.

Take care of the children – demand a promotion!

Good earnings of parents are reliably associated with health, education and, in turn, the situation of their children. Poverty, on the contrary, leads to constant physiological stress, a decrease in working memory and poor academic performance in kindergarten and school.

Biological products: originals and analogues

EU legislation stipulates that the concept of biosimilar does not correspond to the concept of generic. The question of whether the use of biosimilars will make modern treatment more accessible to the majority of the population remains open. The low cost of a biological product may be due to certain losses in its effectiveness and safety.

Epigenetics and cancer: a dangerous gene named BORIS

Epigenetic changes in certain genes can contribute to the development of cancer. A group of researchers from Johns Hopkins University (USA) found that the reverse process – demethylation – is also able to cause the activation of oncogenes.

A deadly virus created by genetic engineers breaks out of a test tube...

There are many such scary, but realistic scenarios that can be thought of. It is clear that some kind of protection is needed from them. But how to defend yourself? After all, genetic engineering is good, and no one is going to give it up. Protection during gene manipulation works is not bad, especially where really dangerous viruses are used. But time goes on, new threats appear…

Medicine of the Future: human embryonic stem cells

The study of embryonic stem cells provides unlimited opportunities for transplant treatment techniques, research of new drugs; it also provides a model for the study of tissue differentiation and allows deeper insight into problems such as infertility and congenital defects of fetal development.

The dream of a Neanderthal

The recent news that European scientists have restored the genome of a Neanderthal made a splash among anthropologists. The most audacious of them even announced that they would undertake – under conditions of sufficient funding – to revive a living Neanderthal. It cannot be said that this plan has already been accepted by someone as a guide to action, but it caused a lot of noise.

Supermuscles made of nanotubes

A material has been created for artificial muscles capable of working equally well in liquid nitrogen and molten iron. The gel is slightly heavier than air, tougher than steel and more elastic than rubber, expands three times in milliseconds and becomes denser when it is stretched.
