Decay of a weak gap and wave propagation in a nonlocal environment with a source
... non-local fourth-order wave equation with a source is considered. The results are set out in terms of the heat transfer theory. The temperature derivative of the source function is positive (a technical source) or negative (a source in biological tissue). The wave velocity (subsonic, sonic, supersonic) is determined with respect to the velocity of propagating heat perturbations. We give examples of the exact solving the problem of disintegration of a weak discontinuity in the temperature field....

Modeling of the stressstrain state of the bone tissue was conducted in the software package ANSYS using finite element method. It is revealed, that change of density of a spongy component ...
IL-1β and IL-8 influence on cytoprotective mechanisms in liver tissue in morbid obesity patients with comorbidities
... increase in the concentration of pro-inflammatory cytokines IL-1β, IL-8 in blood plasma was associated with the development of NAFLD and type 2 diabetes in patients with morbid obesity. It was found that an increase in the expression of HSF1 in liver tissue was positively associated with the presence of steatosis and negatively associated with the expression of AMPK. It was found that a decrease in the expression of NRF2 and TFAM in the liver may indicate mitochondrial dysfunction of hepatocytes. ...
Normal range of liver stiffness measurement in healthy people
... measurement and shear wave velocity in healthy people could not be taken as the reference data for assessing the normal values. Consensus is needed on the subject of normal values of the liver stiffness measurements and shear wave velocity in the liver tissue. Considering the discrepancy between the results of normal liver stiffness values in the sonographic equipment of various manufacturers dynamic observation upon liver stiffness values should be performed using the same machine in the same ...

Disturbance of the vaginal microbiome and the risk of HIV infection in women: analysis of scientific studies
Women are the core population group responsible for new HIV infections and the persistence of the HIV pandemic. A key determinant of susceptibility to HIV infection is the composition of the vaginal microbiome, which can influence the local immune cell population and inflammation status. While a low diversity microbial composition dominated by Lactobacillus crispatus is associated with a reduced risk of HIV infection, a high microbial diversity environment associated with bacterial vaginosis increases...

An environmental analysis of the activity of bioflavonoid accumulation in medicinal plants
This article presents experimental data on the rutin, catechin, and leucoanthocyanin content in medicinal plants (66 species from 31 families). A significant correlation between the catechine and leucoanthocyanin content in plant tissues (r = 0.89) is observed. The study identified promising plant species with a high content of bioflavonoids. These plants can be used as a basis for developing innovative functional foods that exhibit high antioxidant activity.
