[Early measurement of digoxin concentration in blood serum to predict adverse events in older age groups with chronic heart failure and atrial fibrillation.].

To evaluate the effect of early measurement of serum digoxin concentration (SDC) on therapeutical safety and efficacy in patients with recent-onset atrial fibrillation and heart failure. De novo ventricular arrhythmias, high-grade AV node or sinus node blocks were noted in 22%, this risk was positively associated with endpoint SDC (mean SDC 0,88±0,78 ng/mL vs 0,45±0,71 ng/mL, p=0,039) irrespective of baseline characteristics. Empiric calculators for long-term digoxin monitoring correlated with both SDC (r=0,54.

Short Peptides Protect Fibroblast-Derived Induced Neurons from Age-Related Changes.

Neurons become more vulnerable to stress factors with age, which leads to increased oxidative DNA damage, decreased activity of mitochondria and lysosomes, increased levels of p16, decreased LaminB1 proteins, and the depletion of the dendritic tree. These changes are exacerbated in vulnerable neuronal populations during the development of neurodegenerative diseases. Glu-Asp-Arg (EDR) and Lys-Glu-Asp (KED), and Ala-Glu-Asp-Gly (AEDG) peptides have previously demonstrated neuroprotective effects in various models of Alzheimer's disease.

[Prospects for use of short peptides in pharmacotherapeutic correction of Alzheimer's disease.].

Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized by progressive cognitive decline. This review discusses current therapeutic strategies for the treatment of Alzheimer's disease, their limitations, and potential prospects. The feasibility of comprehensive approach for AD therapy is considered in contrast to the classical method in the development of therapeutic strategy.

[Diagnosis of fragility and age resilience from a dynamical systems perspective.].

The concepts of fragility and resilience are often used together to describe elderly people with reduced physical activity. While fragility, which develops with the aging of the body, is a biological syndrome of a decrease in the stressors response resulting from cumulative regression in many physiological systems, and age related a comprehensive assessment of the ability resistance to stress. In this regard, it is important to develop systems and scales for the identification groups of risk among the elderly.

[The influence of peptides on the chondrogenic differentiation of human mesenchymal stem cells during replicative aging.].

Osteoarthritis is a widespread age-related disease, that has no effective targeted therapy. In this regard, bioengineering methods are being actively developed that can stimulate the restoration of cartilage tissue. These methods include chondrogenic differentiation of stem cells, which is stimulated by various biomolecules, including short peptides and polypeptide complexes.
