Anti-hypertension drug stops cancer progression

The results obtained are very promising not only for cancer treatment, but also for the finances of patients. Modern drugs for the treatment of sarcomas cost patients more than $ 10,000 per month, whereas a monthly course of propranolol costs about $ 4.

Biomedicine 15 years ago and today

All technologies (and biomedical ones are no exception) go through the stage of discovery, increased expectations, often a decline, and then either implementation (and a more sober attitude to them), or oblivion if expectations were not met.

A nanorobot that walks by itself

Previously, such molecules could only walk in a given direction in a straight line or in a plane. The new "walker" is able to walk 36 steps on a non-uniform surface, independently deciding where to move the "foot".

-Omics and aging: from biomarkers to systems biology (4)

After decades of simplistic research, specialists began to apply systematic and integrated data analysis "-omik" to the aging process. However, given the complexity of the aging process, new methods are needed to further decipher the numerous interactions.

-Omics and aging: from biomarkers to systems biology (3)

Most of the studies mentioned at the beginning of the article are devoted to the identification of two-dimensional associations of age (or age-related diseases) and any of the "-omic" data types. However, there are pronounced mutual dependencies both between and within the various "-omic" data.
