[Restriction of breastfeeding in the early postnatal period leads to metabolic and endocrine disorders in eighteen-month-old male rats.].

Breastfeeding deficiency in the early postnatal period can lead to metabolic and hormonal disorders in adulthood. However, there are no studies on the effect of starvation in early ontogeny on metabolic and hormonal parameters in aging animals. The effect of such starvation on the functions of the endocrine system has not been practically studied.

[Piezopulsometric analysis of autonomic regulation of the cardiovascular system in an elderly person under stress.].

The article describes the results of using the method of arterial piezopulsometry for non-invasive assessment of the functional state and physiological mechanisms of autonomous regulation of the cardiovascular system (CVS) in an elderly person with acute pain associated with unexpected physical trauma. On the first day, such an effect caused a negative stress reaction in the muscle effectors (ME) of the CVS, provoking an abnormal increase and acceleration of the contractility of the left ventricular myocardium. Analysis of the arterial blood pressure (PP) pulse wave graphs showed that the maximum rate of PP growth - VmaxPP, which reflects myocardial contractility, increased from 625±74 before injury to 2 117±173 mm Hg/s after injury, distorting the contour of the normal PP waveform.

Targeting amyloid clearance in Alzheimer's disease as a therapeutic strategy.

Targeting the amyloid-β (Aβ) peptide cascade has been at the heart of therapeutic developments in Alzheimer's disease (AD) research for more than 25 years, yet no successful drugs have reached the marketplace based on this hypothesis. Nevertheless, the genetic and other evidence remains strong, if not overwhelming, that Aβ is central to the disease process. Most attention has focused on the biosynthesis of Aβ from its precursor protein through the successive actions of the β- and γ-secretases leading to the development of inhibitors of these membrane proteases.

[The effect of Metformin on metabolic parameters and hypothalamic signaling systems in rats with obesity induced by a high-carbohydrate/high-fat diet.].

Metformin (MF), a first-line drug in the treatment of diabetes mellitus, has been used in the recent years to treat obesity. Its therapeutic effect is due not only to the influence on the peripheral tissues, but also on the hypothalamus, which controls food behavior and energy metabolism. The aim was to study the effect of MF therapy (200 mg/kg/day, 8 weeks) in rats with obesity caused by a high-carbohydrate/high-fat diet on the metabolic and hormonal parameters and functional state of the hypothalamic signaling systems.
