Test tube lungs: the first pancake

Scientists transplanted lab-grown lungs to several rats. The organ functioned normally in different individuals from 45 minutes to two hours after transplantation.

Disenfranchised embryos

According to the court, the embryos left "superfluous" after in vitro fertilization are not human beings, and their destruction or use for research complies with the norms of biomedical ethics.

Artificial antigen-presenting cells stimulate immunity better than real ones

Stem cells will cure periodontitis

Researchers at Hiroshima University have grown mesenchymal stem cells derived from the bone marrow of patients, gum tissue, periodontal and dental cement, the destruction of which occurs during periodontitis.

Two more anti-aging products

As we age, the process of cell self-purification, autophagy, becomes less effective. Researchers believe that spermidine inhibits the production of a protein that inhibits the activation of genes responsible for the autophagy process.

Induced pluripotent stem cells against infarction

The study was conducted on mice. This was the first attempt to use induced pluripotent cells (iPS) to treat the heart.

Anti-anti-oncogene: Trim24 vs p53

One of the main functions of the p53 protein is to counteract the replication of potentially oncogenic cells. Trim24 attaches a "black label" to it – the ubiquitin protein, and p53 is destroyed under the influence of specialized protein complexes – proteasomes.

One type of stem cell is good, and two are better

The 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.

Fish, I see right through you!

Vitamins are different

In every third package of multivitamins, the content of ingredients does not correspond to the information on the package. And part of it was also contaminated with lead.

The risk of Alzheimer's disease can be predicted at a young age

These findings are of great interest. However, this does not mean that Alzheimer's disease necessarily begins to develop in a group of young and healthy volunteers who took part in the experiment. To understand whether differences in brain activity in people with a type of ApoE4 gene can really serve as an indicator of the development of Alzheimer's disease over time, only new research will help.

Protein kinase will stop metastases

While the enzyme protein kinase D1 (PKD1) inside cancer cells is active, these cells are not able to move through the tissues of the body. For the first time, the described fundamentals of the mechanism of development of the metastatic form of cancer tumors open up the possibility for the creation of drugs that prevent the development of metastases.

Biotechnology-2009

The Jubilee Fifth Moscow International Congress "Biotechnology: state and Prospects of Development" and the Seventh International Specialized Exhibition "World of Biotechnology 2009" began their work on March 16 this year.

High-tech domestic drugs: the commission is already sitting

The first meeting of the interdepartmental working group on the development of the production of genetically engineered drugs and other high-tech medicines was held in the Ministry of Industry and Trade of Russia.

Sunscreen mustache

American scientists have found a link between the presence of a mustache and a reduced risk of developing lower lip cancer.

To help the surgeon

Thanks to the domestic medical glue from the patient's blood plasma, even deep wounds and severe burns heal faster.

Induced pluripotent stem cells restored the spinal cord

For the first time in the world, the therapeutic effect of human iPSCs has been proven: a month after the operation, all 29 mice paralyzed as a result of spinal cord injury began to walk, and some even run.

Zika virus: another vaccine

After the development of vaccines in the USA and France, the seventh Chinese-French vaccine against Zika virus in the world and the first in Asia has entered the phase of preclinical research.

Another cure for old age?

Caenorhabditis elegans worms exposed to the anticonvulsant drug ethosuccimide lived on average 29 percent longer than the rest.

Anti-cancer tomatoes

Scientists have included two snapdragon genes responsible for the synthesis of anthocyanin in the genome of ordinary tomatoes. As a result, they managed to get dark purple tomatoes with a high content of a useful antioxidant.
