Revealing bactericidal events on graphene oxide nano films deposited on metal implant surfaces.

At the time when pathogens are developing robust resistance to antibiotics, the demand for implant surfaces with microbe-killing capabilities has significantly risen. To achieve this goal, profound understanding of the underlying mechanisms is crucial. Our study demonstrates that graphene oxide (GO) nano films deposited on stainless steel (SS316L) exhibit superior antibacterial features.

Studying perceptual bias in favor of the from-above Necker cube perspective in a goal-directed behavior.

When viewing a completely ambiguous image, different interpretations can switch involuntarily due to internal top-down processing. In the case of the Necker cube, an entirely ambiguous stimulus, observers often display a bias in perceptual switching between two interpretations based on their perspectives: one with a from-above perspective (FA) and the other with a from-below perspective (FB). Typically, observers exhibit a priori top-down bias in favor of the FA interpretation, which may stem from a statistical tendency in everyday life where we more frequently observe objects from above.

Transcranial Magnetic Stimulation of the Dorsolateral Prefrontal Cortex Increases Posterior Theta Rhythm and Reduces Latency of Motor Imagery.

Experiments show activation of the left dorsolateral prefrontal cortex (DLPFC) in motor imagery (MI) tasks, but its functional role requires further investigation. Here, we address this issue by applying repetitive transcranial magnetic stimulation (rTMS) to the left DLPFC and evaluating its effect on brain activity and the latency of MI response. This is a randomized, sham-controlled EEG study.

Psychophysiological Parameters Predict the Performance of Naive Subjects in Sport Shooting Training.

In this study, we investigated the neural and behavioral mechanisms associated with precision visual-motor control during the learning of sport shooting. We developed an experimental paradigm adapted for naïve individuals and a multisensory experimental paradigm. We showed that in the proposed experimental paradigms, subjects trained well and significantly increased their accuracy.

A BCI-Based Vibrotactile Neurofeedback Training Improves Motor Cortical Excitability During Motor Imagery.

In this study, we address the issue of whether vibrotactile feedback can enhance the motor cortex excitability translated into the plastic changes in local cortical areas during motor imagery (MI) BCI-based training. For this purpose, we focused on two of the most notable neurophysiological effects of MI - the event-related desynchronization (ERD) level and the increase in cortical excitability assessed with navigated transcranial magnetic stimulation (nTMS). For TMS navigation, we used individual high-resolution 3D brain MRIs.

[Retrograde intrarenal surgery: a modern view of the problem].

Retrograde intrarenal surgery (RIRS) is a rapidly developing field of endoscopic management of urolithiasis. Previously considered an additional technique in patients with lower calyx stones that do not respond to extracorporeal shock wave lithotripsy, now the RIRS along with percutaneous surgery is gaining a leading position in the management of kidney stones. Currently, it is recommended as the main surgical modality for treating stones less than 2 cm, especially in cases where extracorporeal shock wave lithotripsy is not feasible or not desirable.

[The role of waterjet dissection in improving erectile function and continence after nerve-sparing prostatectomy].

Introduction: Erectile dysfunction (ED) and urinary incontinence (UI) following radical prostatectomy (RP) adversely impact patients psycho-emotional status reducing the quality of life and treatment satisfaction.

Aim: To investigate the rates of regaining continence and erectile function (EF) after nerve-sparing radical retropubic prostatectomy (NS-RRP) and nerve-sparing laparoscopic radical prostatectomy (NS-LRP) in the early postoperative period.

Materials And Methods: The study comprised 116 patients who preserved sexual activity and the ability to have sex.

The pneumatic lithotripter LMA StoneBreaker has been tested and proved effective in removal of uroliths of different location. It is a reliable and comfortable in use modality of contact destruction of the stones of the upper and lower urinary tracts. This lithotripter is perspective for wide urological practice.

Typological features in the behavior of rats.

The existence of internal relationships between measures of investigative and seeking types of activity and the level of anxiety was demonstrated in rats. Individual measures of investigative activity and levels of anxiety were measured using classical methods-the open field test and the elevated plus maze test. The productivity of directed seeking activity was studied using methods developed by ourselves in a universal problem-solving box.

[Differential diagnosis of renal colic].

Potential of modern examinations in differential diagnosis of renal colic and other emergency states is considered. Renal ultrasonography permits in the majority of cases to make diagnosis based on dilatation of caliceal-pelvic system, sometimes with detection of obstruction cause. It is necessary to differentiate parapelvical cysts from dilatation of caliceal-pelvic system, therefore pharmacultrasonic examination of the kidneys with lasix is recommended.

[Magnetic resonance urography: possibilities and prospects].

A new technique of urinary tracts visualization--magnetoresonance urography (MRU)--for a year (2000) was applied in examination of 25 patients aged 17 to 63 years with ureteral concrements (n = 11), ureteropelvic stenosis (n = 10), ureteral stenosis (n = 2), urinary bladder tumor (n = 1), Ormond's disease (n = 1). MRU provides the same information about the obstruction and dilatation of the urinary tracts as excretory urography (EU). In cases of EU contraindication (allergy, renal failure) or lack of contrast substance excretion, MRU allows to avoid additional invasive diagnostic procedures.
