The Role of Pepsinogenes and Some Intestinal Hormones in Pathogenesis of Gastroesophageal Reflux Disease
80 patients with gastroesophageal reflux disease (GERD) were examined. The diagnosis of GERD was based on the history of the disease, complaints of patients, the results of daily monitoring of pH in the lower third of the esophagus, data of fibroesophagogastroduodenoscopy, chromoendoscopy, 13C-octanoic breath test, gastrin-17 (G-17) concentration, pepsinogens I and II (P I and II) and cholecystokinin-pancreozymin (C-P) in serum.After 24 hours pH monitoring of the lower third of the esophagus in 40 patients with GERD, the predominance of acid was found, and the other 40 patients had mixed refluxes. In patients with predominance of acid reflux, the mean values of half-life of solid food evaluation (T1/2) according to 13C-octanoic breath test was (45.25±1.34) min. With the predominance of mixed refluxes in patients, there was a tendency towards hypokinetic motility of the stomach, indicating a slowdown in half-life of solid food evaluation from the stomach up to (139.24±11.87) min. With the predominance of acid reflux also was observed a significant reduction in the concentration of G-17 and C-P, an increase in P I and a decrease in the concentration of P II. Hypergastrinemia, high levels of C-P and P II (37.44±3.41) μg/l (p<0,05) were diagnosed with the predominance of mixed refluxes
Interlevel absorption of electromagnetic waves by nanocrystal with divalent impurity
The energy spectrum of central divalent impurity is calculated using the
effective mass approximation in a spherical quantum dot (QD). The dipole moment
and oscillator strength of interlevel transition is defined. The dependence of
linear absorption coefficient on the QD size and electromagnetic frequency is
analyzed. The obtained results are compared with the results of univalent
impurity.Comment: 8 pages, 8 figure
Композиція та юкстапозиція як засіб номінації в заголовках періодичних інтернет-видань (Сomposition and juxtaposition as a means of nomination in periodical online editions)
У статті проаналізовано одиниці монолексемної організації (композити, юкстапозити) як інновації у заголовковому комплексі, визначено граматичні параметри компонентів, продуктивні моделі.
(Language of press has a number of characteristic features defined by its creative nature and determinative functions. The language itself stands for the sphere or research field of constant search of new means for readers’ persuasion and influence creating, in this way, vast possibilities for appearing new words – neologisms – of different structure and semantics. Neologism
as a new lexical unit is a linguistic sign of certain concept determined by cognitive structure of native speaker. Formally it can be presented as a single compound word (composites, juxtaposites) or a phrase, which is an analytical morpheme.
This article deals with the units of monolexemic organization (composites, juxtaposites) as innovations functioning in the headings of online editions, reveals the complex mechanism of productive derivative models and the linguistic nature of different motivations.
The objective and attributive relations between the components of innovative composites are being analyzed, along with the origin (Ukrainian or foreign) and semantic structure (figures, proper or common names representing the first or second element of neologism) of constituent parts of juxtaposites in the headings of periodical online editions. The grammatical parameters of their components and productive models are also defined. Linguistic analysis reveals that nouns are most often
used as components of monolexemic innovative units.
Light absorption coefficient of an ordered array of spherical quantum dot chains
We considered intersubband electron transitions in an array of
one-dimensional chains of spherical quantum dots in the
GaAs/AlGaAs semiconductor system. The absorption coefficient
caused by these transitions was calculated depending on frequency and
polarization of incident light and on Fermi level position, and temperature. We
established the existence of two maxima of the absorption coefficient at the
edges of the absorption band. It is shown that the absorption coefficient
reaches its maximal value at the center of the region between the -,
-like subbands and slightly varies with temperature. The change of the
direction of the linearly polarized light wave incident on the chains from
perpendicular to parallel leads to a sharp narrowing of the absorption band. It
is obtained that the absorption bandwidth increases with the reduction of the
quantum dot radius. We also analyzed the dependence of the absorption
coefficient of GaAs/AlGaAs superlattice on concentration of
aluminium in the matrix.Comment: 9 pages, 7 figure
Трансформовані фраземи як детермінанти експресивності в заголовках періодичних Інтернет-видань
У статті репрезентовано напрями розгортання фразеологічних трансформацій як виразні прийоми експресивізації заголовків інтернет-видань.
(The article represents the directions of evolution of idiomatic transformations as expressive a technique in the processes of «expressivisation» in the headings of periodical online edition. It is revealed that transformed phraseological units carry out
a reinforced impact on the recipient making the topic of utterance more clear and distinct, produce imaginative characteristic and create the effect of convergence of the recipient, attracting attention for its expressiveness. Occasional transformation of
the analyzed units is being perfoemed in several ways. The first way – it is occasional explication when one more imaginative component is being added to the idiomatic complex by the author’s creative intention. This way also contains the attributive,
objective and combined subways. The second way – it is occasional substitution when the replacement of certain lexical component takes place. Such a substitution of one of the components of lexical permanent structure allows one to weave easily occasional component to the overall semantic, notional and intentional frame of online headings. It is investigated that occasional
substitution can be made not only by lexical but also derivational means when the derivative morpheme stands for attached modifier (often dependent) of phraseological unit. Occasional derivation of constant idiomatic units, determined to meet the need of author’s intentions, is manifested in two ways: first, it is situationally caused by the transformation of the outer form of
expression; secondly, by the transformation of the contents of expression at the constant (unaltered) form of expression.
Analysis of the effect of polarization traps and shallow impurities on the interlevel light absorption of quantum dots
A spherical quantum dot (QD) heterosystem CdS/SiO has been studied. Each
QD has a hydrogen-like impurity in its center. Besides that, it has been
accounted that a polarization trap for electron exists at the interfaces due to
the difference between the QD and matrix dielectric permittivity. It has been
defined that for small QD radii there are surface electron states. For
different radii, partial contributions of the surface states into the electron
energy caused by the electron-ion and electron-polarization charges interaction
have been defined. The linear light absorption coefficient of noninteracting
QDs has been calculated taking into account the QD dispersion by the size. It
is shown that the surface states can be observed into different ranges of an
electromagnetic spectrum.Comment: 8 pages, 4 figures, 1 tabl

Dynamics of Bone Trap-5b Level in Patients with Bone Metastases of Renal Cell Cancer at Combined Treatment
The objective of this study was to determine the sensitivity of tartrate-resistant acid phosphatase (Bone TRAP-5b) for early detection of bone metastases (BM) and to investigate the efficacy of bisphosphonates (BF) (zolendronic acid-ZA) in prevention of bone metastases in patients with Renal Cell Carcinoma (RCC). The 60 patients with RCC with proven BM were investigated to assess the sensitivity and specificity of Bone TRAP-5b. 95 patients with RCC with high level of tartrate-resistant acid phosphatase (Bone TRAP-5b) (8,5±0,2 IU/L) after radical surgical treatment were divided into two groups: 1-st group: (n=44) received zolendronic acid (ZA) (BF +), and 2-nd group (n=51) patients didn\u27t receive ZA (BF-). Patients of both subgroups were similar by age, sex, stage of disease. The levels of Bone TRAP-5b, Ca++, alkaline phosphatase, LDG were accessed every 3 months, and MRI imaging, bone scan with 99mTc every 6 month in both groups. We determined the high correlation between bone TRAP-5b and the presence of bone metastases (r=0,9; p <0,05), but its level wasn\u27t dependent with the number of BM. The results showed the high sensitivity and specificity of Bone TRAP-5b at the critical value of 5.2 IU/L (98,3 % and 90,0 %), (χ2=64,6; p<0.01). Using BF for the prevention of bone metastases in high risk group patients with RCC provides a significant difference in the incidence of bone metastases in patients
Effect of quantum dot shape of the GaAs/AlAs heterostructure on interlevel hole light absorption
The effect of quantum dot shape on the hole energy spectrum and optical
properties caused by the interlevel charge transition based on the 4x4
Hamiltonian has been studied for the GaAs quantum dot in the AlAs semiconductor
matrix. Calculations have been carried out in perturbation theory taking into
account the hybridization of states for cubic, ellipsoidal, cylindrical and
tetrahedral shapes by changing the volume of a quantum dot. Based on the energy
calculations and on the determined wave functions of the hole states we have
defined the selection rules and the dependence of the interlevel hole
absorption coefficient on QD shapes and volumes.Comment: 10 pages, 6 figure
