THE LEPTIN GENE IS A MARKER FOR THE CELL THERAPY OF METABOLIC SYNDROME
Authors: Petrova N. V. 
Published: September 2019

It is shown that the level of the Lep gene expression is a marker for B/Ks-Leprᵈᵇ/+ mice, which line serves as an optimal model for describing metabolic syndrome (MS) in preclinical studies. Mice were transplanted with cultured isogenic bone marrow cells (BMC) from heterozygous db/+ donors. The recipients were divided into two groups according to an early or advanced stage of MS development. We analyzed the expression of the Lep gene on the 3rd, 8th and 14th day following the administration of stem BMCs in the brain, liver and pancreas cells by polymerase chain reaction (PCR) in real time. The Lep gene expression was evaluated in terms of the number of cDNA copies. According to our data, leptin is a complete regulator of metabolic processes due to its effect on the hypothalamus, which, together with the hippocampus, controls the production of acetylcholine and insulin in the brain. We have proven the role of the Lep gene as a quantitative criterion for evaluating the effi cacy of a cell therapy in MS.

This work was aimed at investigating the effect of maral antler powder on the activity of animal hematopoietic stem cells both in vivo and in vitro.For in vivo experiments based on the model of sleep deprivation, male mice of the CBA/CaLac line were used. Prior to the experiment, mice in the experimental and control groups were intragastrically administered with a water dispersion of a maral antler powder and distilled water, respectively. Subsequently, the extraction of bone marrow from the femur, cloning of erythro- and granulo-monocytopoiesis precursors and count of the number of cell colonies were performed. Experiments in vitro involved the extraction of bone marrow cells from the femur followed by their cultivation both in a culture containing a maral antler powder (experimental) and distilled water (control culture). The number of CFU was counted 7 days following the beginning of the experiment.Maral antlers are found to exhibit no noticeable modulating effect on the colony-forming activity of mouse hematopoietic stem cells in vitro. However, according to our in vivo experiments on mice, a preventive administration of an antler powder before a stressful infl uence (sleep deprivation) prevents suppression of erythropoiaesis processes, thus exhibiting a modulating effect on the activity of CFU-E and CFU-GM by increasing the number of CFU-E and reducing the number of CFU-GM by more than three times. The modulating effect of maral antlers on the activity of hematopoietic and stem cells is based on the infl uence of biologically active substances contained therein on the neuroendocrine regulation of the hematopoietic system occurring in living organisms.

In this paper, we have studied the analysis of current distributions and radar cross sections of line source scattering from impedance strip. The problem was solved with fractional derivative method previously. Here, the specific case of fractional derivative method is investigated. The problem under consideration on the basis of various methods is studied well, however, they are mainly done by numerical methods. The fractional derivative method, allows an analytical solution in a specific situation. This method allows to obtain analytical solution of impedance strip for a special case which is fractional order is equal to 0.5. When fractional order is 0.5, there is an analytical solution which is explained and current distribution, radar cross section and near field patterns are given in this paper. Here, as a first time, current distribution, bi-static radar cross section and near field for the upper and lower part of the strip are studied.

Published: September 2019

Deception of navigational subsystems of a client, ranging from a hunting GPS receiver to the military-class GNSS receiver onboard of a Cruise Missile, is one of the probable electronic attacks. One of the simplest and practical way too deceive these receivers is to re-broadcast the delayed navigational signals. The authors were studied the feasibility of this method in the “Best” attainable conditions while the generality of study retained. The results from introduced geometrical and mathematical models were used to define the minimum and maximum operational range of Repeater Deception System parametrically. Then the parameters were substituted by information of various GNSS constellations. Investigation of reliability of selected EW scenario concluded the article.
