К ВОПРОСУ О КОНКУРЕНТОСПОСОБНОСТИ ВУЗА
The article studies in depth the competitiveness of universities in market conditions; underlining the approach that university’s sustainable development supposes continuing accumulation of features that allow university to adapt itself to competitive environment and to occupy the most advanced market position within it. The author refers to broad spectrum of topics that support this point of view. The article deals with the notion of network repartition of expertise, particularly pointing out the importance of approach that is based on impression translation. The author argues that the efficiency of the network should result in functioning confidence. Other topics considered in the article are requirements for higher education, criteria of university and syllabus choice, and diversified factors of competitive environment, network environment as integrative factor of reciprocal interests. The author, analyzing dependencies of educational conditions and existing training services offered by universities, draws one’s attention to the necessity to actualize confidence in global information network, as well as in social assessments and impressions on graduates which are shaped out within it.Потребности в высшем образовании.

SRT1720 improves survival and healthspan of obese mice
Sirt1 is an NAD+-dependent deacetylase that extends lifespan in lower organisms and improves metabolism and delays the onset of age-related diseases in mammals. Here we show that SRT1720, a synthetic compound that was identified for its ability to activate Sirt1 in vitro, extends both mean and maximum lifespan of adult mice fed a high-fat diet. This lifespan extension is accompanied by health benefits including reduced liver steatosis, increased insulin sensitivity, enhanced locomotor activity and normalization of gene expression profiles and markers of inflammation and apoptosis, all in the absence of any observable toxicity. Using a conditional SIRT1 knockout mouse and specific gene knockdowns we show SRT1720 affects mitochondrial respiration in a Sirt1- and PGC-1α-dependent manner. These findings indicate that SRT1720 has long-term benefits and demonstrate for the first time the feasibility of designing novel molecules that are safe and effective in promoting longevity and preventing multiple age-related diseases in mammals
Evidence for a Common Mechanism of SIRT1 Regulation by Allosteric Activators
A molecule that treats multiple age-related diseases would have a major impact on global health and economics. The SIRT1 deacetylase has drawn attention in this regard as a target for drug design. Yet controversy exists around the mechanism of sirtuin-activating compounds (STACs). We found that specific hydrophobic motifs found in SIRT1 substrates such as PGC-1α and FOXO3a facilitate SIRT1 activation by STACs. A single amino acid in SIRT1, Glu[superscript 230], located in a structured N-terminal domain, was critical for activation by all previously reported STAC scaffolds and a new class of chemically distinct activators. In primary cells reconstituted with activation-defective SIRT1, the metabolic effects of STACs were blocked. Thus, SIRT1 can be directly activated through an allosteric mechanism common to chemically diverse STACs.Glenn Foundation for Medical ResearchEllison Medical FoundationJuvenile Diabetes Research Foundation InternationalUnited Mitochondrial Disease FoundationNational Institutes of Health (U.S.)National Institute of Allergy and Infectious Diseases (U.S.

SRT2104 extends survival of male mice on a standard diet and preserves bone and muscle mass
Increased expression of SIRT1 extends the lifespan of lower organisms and delays the onset of age-related diseases in mammals. Here, we show that SRT2104, a synthetic small molecule activator of SIRT1, extends both mean and maximal lifespan of mice fed a standard diet. This is accompanied by improvements in health, including enhanced motor coordination, performance, bone mineral density, and insulin sensitivity associated with higher mitochondrial content and decreased inflammation. Short-term SRT2104 treatment preserves bone and muscle mass in an experimental model of atrophy. These results demonstrate it is possible to design a small molecule that can slow aging and delay multiple age-related diseases in mammals, supporting the therapeutic potential of SIRT1 activators in humans
