AbstractThe motor deficits observed in patients following some lesions of the central nervous system may be viewed as falling at one extreme of the continuum of possible motor behaviours. They are usually associated with an impaired ability to select and control specific movements from the available repertoire. Such movements may not be viewed as abnormal. However, it is unlikely that the primary motor deficits can all be considered adaptive.

The objective: to present information about potential mechanisms of development of sepsis-associated encephalopathy, and its potential role in sepsis outcome.Neurohumoral regulation is the most important system that integrates many functions of variable values to achieve the final result that is beneficial for the host. The central nervous system (CNS) is the switch and control mechanism responsible for the functioning of this system. The increasing number of studies indicating the relationship between the development of sepsis and occurrence of qualitative and quantitative changes in the central nervous system suggests that it is the degree of damage to neurohumoral regulation mechanisms at the very beginning of the disease can significantly determine the severity of the course and prognosis of the outcome of multiple organ failure syndrome in sepsis.

The purpose of the study was to develop a mathematical mechanism which could describe laws of changing electrical signals in nerve fibers in man’s lower extremities and hip prosthesis movement. The article presents a schematic diagram of the bioelectric hip prosthesis control system, main elements of which are an actuator, a control device, and a primary data unit. There are given actual mathematical models of prostheses movement and control signals of man’s central nervous system; on their base was designed the mathematical model controlling bioelectric hip prosthesis movement. A specific feature of the model offered is that the model has a function to characterize a signal transfer from the central nervous system to the actuator of prosthesis. The research results can be applied in the course of hardware and software implementation of bioelectrical prostheses, taking into account physical abilities of the users, creating specific algorithms, studying electric and dynamic characteristics of these devices.

Opioid peptides exhibit a wide-ranging tissue distribution and control multiple tissue functions not only through reflex mechanisms involving the central nervous system or the modulation of neurotransmitter release, but also by acting directly at the cellular level by targeting selected receptor subtypes (μ, δ, and κ are among the most frequently expressed) [...]

Rabies is an acute viral infection of the central nervous system, caused by a lyssavirus in the family Rhabdoviridae. It is zoonotic viral disease that can affect all mammals, including humans, cats, dogs, and wildlife and farm animals. The virus is present in the saliva of affected animals, and the most frequent method of transmission to humans is by bites, scratches or licks to broken skin or mucous membranes. The disease has a long incubation period (six months) and symptoms may take several weeks to appear after infection. The first clinical symptom is neuropathic pain at the site of infection or wound due to viral replication. Diagnosis can only be confirmed by laboratory tests preferably conducted post mortem on central nervous system tissue removed from cranium. This paper reviews the possible prevention and control of rabies. Essential components of rabies prevention and control include ongoing public education, responsible pet ownership, routine veterinary care and vaccination, and professional continuing education. Control strategies include quarantine, confirmation of diagnosis, determining the origin and spread of an outbreak. Since rabies is invariably fatal and deadly viral disease that can only be prevented the collaborative effort between Veterinarians and human health care professionals are needed in the prevention and control of rabies.
