Epigenetic Contributors to PTSD: a Comprehensive Review.

Background: Post-traumatic stress disorder (PTSD) is a complex condition triggered by traumatic events. The molecular mechanisms underlying PTSD are not fully understood, but epigenetic modifications, particularly DNA methylation, may play a key role. The objective of this review was to identify the most significant epigenetic markers associated with PTSD.

Non-invasive EEG-based BCI spellers from the beginning to today: a mini-review.

The defeat of the central motor neuron leads to the motor disorders. Patients lose the ability to control voluntary muscles, for example, of the upper limbs, which introduces a fundamental dissonance in the possibility of daily use of a computer or smartphone. As a result, the patients lose the ability to communicate with other people.

Information-Thermodynamic Method for the Study of Proliferation of Organized Cellular Structure.

The aim of the article was to develop an innovative method for the study of cell proliferation based on the information-thermodynamic approach, including the mathematical ratio-the entropy of cell proliferation and an algorithm for the calculation of fractal dimension of the cellular structure. Approbation of this method with pulsed electromagnetic impact on culture in vitro was implemented. It is shown on the basis of experimental data that the organized cellular structure of juvenile human fibroblasts is a fractal.

X-ray and anatomical features of the lower jaw alveolar cortical layer in children.

Introduction: the world studies showed the interest in measurement of the buccal or anterior cortical plate thickness. Data indicate a significant superiority of the spongy substance over the compact one in the distal part of the jaw, which makes it possible to think about a higher effectiveness of transcortical injections. The empirical "rule of 10″ provides for the choice of a method of anesthesia in children for primary teeth but demonstrates difficulties with high-quality anesthesia accompanied for permanent teeth.

Stroke Affected Lower Limbs Rehabilitation Combining Virtual Reality With Tactile Feedback.

In our study, we tested a combination of virtual reality (VR) and robotics in the original adjuvant method of post-stroke lower limb walk restoration in acute phase using a simulation with visual and tactile biofeedback based on VR immersion and physical impact to the soles of patients. The duration of adjuvant therapy was 10 daily sessions of 15 min each. The study showed the following significant rehabilitation progress in Control ( = 27) vs.

A P300 Brain-Computer Interface With a Reduced Visual Field.

A P300 brain-computer interface (BCI) is a paradigm, where text characters are decoded from event-related potentials (ERPs). In a popular implementation, called P300 speller, a subject looks at a display where characters are flashing and selects one character by attending to it. The selection is recognized as the item with the strongest ERP.
