[Methods for assessing the electrophysical properties of body tissues and the possibility of their application in forensic medical practice].

This article provides an overview of some diagnostic methods for indicators and changes in the electrophysical properties of biological tissues. The key principles of assessing the electrical conductivity and resistance of tissues under the influence of alternating and direct current electric charge using standard and modified meters and signal generators, as well as the possibilities of digital improvement of computational models, are considered. Some existing and promising methods are presented that enable to solve important problems of forensic medical practice by registering changes in electrophysical parameters.

[Study of certain electrophysical properties of adipose tissue in the postmortem period when working with a direct current source].

Unlabelled: Some features of changes in the electrophysical properties of adipose tissue of animal origin in the postmortem period when working with direct-current sources are considered.

Objective: Evaluate experimentally the possibilities of registering changes in the electro-physical properties of biological tissues using a direct current source when working with a specific resistance as well as to identify the possible recorded changes in biological tissues when a reverse electromotive force and polarization phenomena occur. At the first stage the fatty subcutaneous layer of a pig was used as samples of adipose tissue which is closely similar to human adipose tissue in composition.

Risk factors associated with exposure to bovine respiratory disease pathogens during the peri-weaning period in dairy bull calves.

Background: Bovine respiratory disease (BRD) remains among the leading causes of death of cattle internationally. The objective of this study was to identify risk factors associated with exposure to BRD pathogens during the peri-weaning period (day (d)-14 to d 14 relative to weaning at 0) in dairy bull calves using serological responses to these pathogens as surrogate markers of exposure. Clinically normal Holstein-Friesian and Jersey breed bull calves (n = 72) were group housed in 4 pens using a factorial design with calves of different breeds and planes of nutrition in each pen.

The effect of "Jelly" CdTe QD uptake on RAW264.7 monocytes: immune responses and cell fate study.

Encapsulation of Quantum Dots (QDs) has become an essential factor which regulates particles cytotoxicity, as well as physical and chemical stability. Negatively charged cellular membranes have a great affinity to nanoparticles with surface molecules carrying positive charge, hence creating perfect conditions for fast and aggressive intracellular penetration. The preference for non-charged outer shells is topical in QD design and various applications.

Mesenchymal stem cell therapy promotes corneal allograft survival in rats by local and systemic immunomodulation.

Mesenchymal stem cells (MSCs) are being investigated extensively due to their ability to dampen immune responses. Here, we tested the ability of MSCs from three distinct sources to prolong rat corneal allograft survival. A fully allogeneic rat cornea transplant model (DA to LEW) was used.
