Interleukin 2 as a potential cancer marker in patients after kidney transplantation.

Introduction: Transplant recipients have a significantly greater incidence of cancer, compared with the general population, who are referred to immunosuppressive therapy as an additional malignancy risk factor. Therefore, there is a need to search for an easy in clinical practice neoplasm predictor, especially for this group of patients.

Materials And Methods: A group of 74 (43M and 31F; aged 46.

Socio-demographic characteristics of patients with diagnosed functional dyspepsia.

Introduction: The term "dyspepsia" comes from the Greek words "dys' and 'peptin", which maen "ill digestion" or indigestion, although this set of symptoms in the adult clinic has little to do with the digestion or absorption process, and refers more to ailments related to the upper section of the gastrointestinal tract.

Aim: Assessment of the frequency of functional dyspepsia diagnosis, the characteristics of the group and an attempt to identify the accompanying symptoms, assessment of histological lesions and an attempt to answer question about the efficiency of anti-secretory and eradication therapy.

Material And Methods: The study involved patients reporting for gastrofiberscopic examination due to dyspeptic ailments.

Assessment of significance of features acquired from thyroid ultrasonograms in Hashimoto's disease.

Introduction: This paper concerns the analysis of the features obtained from thyroid ultrasound images in left and right transverse and longitudinal sections. In the image analysis, the thyroid lobe is treated as a texture for healthy subjects and patients with Hashimoto's disease. The applied methods of analysis and image processing were profiled to obtain 10 features of the image.

[Characteristic and endoscopic evaluation of dyspeptic patients].

Unlabelled: Dyspeptic sypmtoms are common in our population and are typical for upper gastrointestinal tract disease. Endoscopy is commonly performed to evaluate symptoms of dyspepsia, especially in older patients after 45 years or with alarm symptoms. The aim of this study was to charaterize patients who receive endoscopy for dyspepsia and to analyse their endoscopic findings.

Relation between the substituent effect and aromaticity.

Molecular geometries of benzene and its 18 monosubstituted derivatives were optimized at B3LYP/6-311+G** level of theory. The changes of pi-electron delocalization of the benzene fragment were estimated by use of aromatic stabilization energies (ASE) based on different homodesmotic reaction schemes, geometry-based HOMA model, magnetism-based NICS, NICS(1), NICS(1)zz, and an electronic delocalization index, PDI, derived from the AIM theory. Apart from aromatic stabilization energies the other descriptors of aromaticity vary to a very small extent, indicating high resistance of the pi-electron structure to the substituent effect.

Extent of cyclic pi-electron delocalization modification in exocyclically substituted fulvenes.

Fulvene derivatives, 20 mono- and 14 di-exocyclically substituted, were optimized at the B3LYP/6-311+G level of theory. Aromaticity indices include aromatic stabilization energy (ASE), Schleyer's Nucleus Independent Chemical Shift (NICS), (3)He chemical shifts, anisotropy and exaltation of magnetic susceptibility, and the Harmonic Oscillator Model of Aromaticity (HOMA), which is a geometry-based descriptor. These indices were used to estimate the extent of a cyclic pi-electron delocalization due to the substituent effect.
