Prostate adenoma? Try Botox!

An effective reduction in the size of the prostate gland occurred in 73% of patients with prostate adenoma who used a dose of botox in 100 units, and in 81% of those who used a dose of 300 units. As a result, the improvement was 30% relative to the initial state.

Cardiomyocytes from stem cells

Mesodermal cells capable of forming bone, blood, skeletal muscle and other tissues, when added to the culture medium of Baf60c, Tbx5 and Gata4 factors, turned only into cardiomyocytes, which rhythmically contracted like normal heart muscle cells.

Embryos for spare parts: it's time to discuss the problem

In England, a debate is raging about whether it is permissible to use embryos to obtain stem cells. Scientists believe that in 10 years stem cells can be used to treat various diseases. In addition, embryos can be used to grow new organs – "spare parts" for the body.

Nanofiber tendons

To create artificial tendons, Bosworth twisted a biodegradable nanofiber in a special way, which can be implanted into the human body. The resulting "tissue" is similar in structure to the natural one and can be transplanted to the site of the rupture. It will promote fusion, and the artificial polymer replacement will gradually disappear, and its own connective tissue will form in its place.

Cell reprogramming: proteins instead of genes

In their publication, the scientists note that the "protein-induced pluripotent stem cells" they obtained, like their classical counterparts, are able to transition back into a specific state and form the tissues of developing mouse embryos.

Human genome put up for auction

In 2003, geneticists completed many years of work on compiling a kind of human DNA map. Then the program cost research organizations $3 billion. Now the genome will go under the hammer on eBay; the initial price of the lot is $68,000.

The cow genome has been sequenced

The first paper describes the results of work on reading the complete genome of a cow of the famous Hereford breed selected for sequencing. In the second – the results of a side project that cost a hundred times less – comparison of the genome of almost 500 cows of 19 different breeds for 37740 single-nucleotide polymorphisms ("snips").

The world's first transgenic puppies glow red

The first cloned puppy was born in 2005, and dogs have been cloned more than once since then, but now, before the transfer of the nucleus, the fibroblast culture was infected with a modified retrovirus with an embedded gene of the red fluorescent anemone protein. Five glowing dogs feel good and glow like Kremlin stars under an ultraviolet lamp.

Lipid nanoparticles – a step towards targeted cancer gene therapy

The results of clinical studies of the cancer gene therapy method using lipid nanoparticles have shown that the oncosuppressor gene p53 restores the normal functioning of the genetic system for controlling cell growth, and the lipids that make up the shell of the nanoparticles dissolve without side effects.

Anniversary of the "grandmother of modern neuroscience"

"I am deeply excited that I have reached the age of 100, having lived a life with joy, which, I think, few have experienced. I'm not afraid of death, it doesn't matter to me when it comes," Nobel laureate, neuroscientist, Senator for life Rita Levi–Montalcini told reporters on the eve of the anniversary.

Induced pluripotent stem cells: fibroblasts are optional

To create induced pluripotent stem cells, scientists used hemocytoblasts, precursors of all types of blood cells. In the process of cultivation, scientists by the method of transduction introduced reprogramming factors into them – genes whose expression is observed in embryonic stem cells.

Genes that prevent aging are being sought

Genes common to humans and rodents have been identified, the activity of which changes during aging. With age, 56 of them increase protein expression, and 17 others decrease activity. The results of the study suggest that genes are able to adapt to aging, participate in the protection of the body during this process and even slow it down.
