Introduction: Diffusion weighted imaging (DWI) is a form of magnetic resonance imaging (MRI) based on measuring the random Brownian motion of water molecules within a tissue. The aim of this study was to show the significance of diffusion-weighted imaging (DWI) in differentiating pancreatic cystic formations from normal pancreatic parenchyma using MRI 1.5 T.Methods: A total of 52 patients were included in the study (25 with pancreatic cystic formations and 27 with normal MRI findings of the pancreas). DWI technique was used with b values of 0.500 and 1 000 mm2/s at 1.5 T. The signal intensity was measured, as well as apparent diffusion coefficient (ADC). Visual estimation of the signal intensity of detected cystic lesions was performed and compared to the normal appearance of pancreas.Results: The highest signal intensity of the cystic lesions with hyper-signal was observed with DWI b0 value in the pancreatic head (M 185.1 ± 47.205, p 0.05.Conclusions: Differences in signal intensity and ADC values have an important diagnostic value in differentiating the cystic formations from normal pancreatic parenchyma in MRI examination.

Cognitive functions can be assessed and followed up over a period of time with cognitive evoked potentials (CEP) P300. In this context, brainstem auditory evoked potentials (BAEP) are most commonly used, but visual evoked potentials (VEP) are utilized as well. The research in this area has demonstrated that these techniques could be used as a supplemental method in diagnostics of numerous diseases such as Alzheimer's disease, mild cognitive impairment, vascular dementia, epilepsy, craniocerebral trauma, Parkinson's disease, multiple sclerosis, and other degenerative diseases. In addition, P300 can also be used as an auxiliary method in the diagnostics of mental disorders conditions such as schizophrenia, panic disorders, narcotic drug addiction, nicotinism, alcoholism, etc. The method assists in monitoring the course of diseases leading to encephalopathy, such as liver and kidney damage and grave anaemia. The advantages of P300 testing are easy application, non-invasiveness, and an unlimited number of potential applications. Moreover, the results obtained with this method are measurable and can be compared.

A trigonometric series strongly bounded at two points and with coefficients forming a log-quasidecreasing sequence is necessarily the Fourier series of a function belonging to all $${L^{p}}$$Lp spaces, $${1\leq p < \infty}$$1≤p<∞. We obtain new results on strong convergence of Fourier series for functions of generalized bounded variation.

Appian’s Illyrian book ( Illyrike ) was originally intended to be just an appendix to his Macedonian book and today remains the only extant ancient work dealing with the early history of Illyricum which is preserved in its entirety. In this short work Appian puts together different local and regional histories in order to create a unified historical narrative and determines the historical and mythological coordinates of Illyricum inside the ancient world. This paper will discuss Illyrike in the context of the Roman construction of Illyricum as a provincial space, similar to some other regions in continental Europe such as, for example, Gaul or Britain. They were all firstly created through the needs of Roman political geography and later written into literary knowledge through the works of ancient history and ethnography. This paper will argue that Appian’s Illyrik e represented the final stage of the Roman construction of Illyricum from an imaginary to a provincial space, which was the point of its full coming of age as an integral part of the ancient world and the Roman Empire.
