Gene therapy vaccine against immunodeficiency virus: encouraging results

In fact, monkeys were infected with immunity to HIV, providing protection from acquired immunodeficiency syndrome with the help of an adenovirus encoding antibodies to the monkey immunodeficiency virus – the monkey analogue and, possibly, the "progenitor" of HIV. If the method proves effective for the human immunodeficiency virus, mass vaccination can eradicate the pathogen.

It is assumed that these diseases may be interrelated. But are Alzheimer's disease and diabetes a natural stage of cell aging or a consequence of the influence of harmful factors characteristic of modern life – overeating, stress and a sedentary lifestyle?

The Secret Power of Pheromones

The influence of pheromones on human sexual behavior has been studied quite recently. The information that reaches the mass reader is often based on speculation, guesswork and the results of research conducted with the money of companies producing "love elixirs". But how much can you trust the promises on their labels?

"Fuhrer's Children" – compromising evidence on eugenics

The solution of demographic problems in Hitler's Germany was based on the Nazi "racial doctrine", and it, in turn, referred to eugenics – the science of improving the hereditary properties of a person. As a result, eugenics was compromised for a long time.

Golden milk of transgenic mice

Our scientists, together with specialists from Belarus, have learned how to extract from transgenic mice from 15 to 40 grams of human lactoferrin per liter of milk. This is many times more than that of a female nurse. Abroad, at best, they extract only half a gram for the same amount of product.

Magnetic Nanoparticles Help stem cells build bones

When growing artificial bones, you can do without matrices. Instead, a suspension of magnetic nanoparticles can be added to the stem cell culture: under the influence of an external magnetic field, cells line up in the same linear structures as in bone tissue.

Induced pluripotent stem cells: micro-RNAs instead of potential oncogenes

To reprogram skin cells and transform them into pluripotent cells that do not differ in properties from embryonic cells, it is possible to use not the delivery of "pluripotency genes" into their nuclei, which are potential oncogenes, but the introduction of micro-RNAs characteristic of embryonic cells.
