The purpose of the study was to analyze the cumulative incidence of hematological neoplasia and evaluate the dynamics of this in different regions of Cherkasy oblast in 1980, 1989, 2001, 2014 yy. Materials and methods. The epidemiological parameters of hematological neoplasms in the radiation-contaminated (RC), chemically contaminated (CC), radiation and chemically contaminated (RCC), conditionally clean (CNC) regions of Cherkassy oblast (CO) in 1980, 1989, 2001, 2014 yy. were analyzed. Classification of CO territories to the RC, CC, RCC, CNC regions was conducted based on reports of the dosimetry certification of all settlements of Ukraine after the Chernobyl accident and the results of determination of the level of chemical contamination by the sanitary and epidemiological service during 1980-2014 yy. Results. It was determined, that, at the limit of statistical significant (p = 0.057), on the RC territory of CO in 2001 year the relative risk for the cumulative incidence of hematologic neoplasia was on 1.41 times higher (18,682 (95 % confidence interval (CI) = 14,426 – 16,879) against 13,187 (95 % CI = 9,495 – 16,879)), compared with CNC region. In addition, in the RC territory from 1989 to 2001 year the increasing at 9,342 times (1,999 (95% CI = 0.69–3.305) versus 18,682 (95% CI = 14.426 – 16.879)) of cumulative incidence of the hematopoietic and lymphoid systems neoplasm was detected. It is proved, that in the CNC region from 2001 to 2014 year at 1,791 times (13,187 (95% CI = 9.495 – 16.879) versus 23,619 (95% CI = 18.412 – 28.826)) higher level of the cumulative incidence of hematologic neoplasia was observed. Conclusions. In the CO, which was polluted by the radiation factor because of the Chernobyl nuclear power plant accident, 5 years after that, in 2001 was detected the increasing of the relative risk of hematologic neoplasia, compared to that on the CNC region. In addition, on the RC territory from 1989 to 2001 year the increasing at 9,342 times of the incidence of hematopoietic and lymphoid system tumors was observed. This is evidence of pro-leukemic effects of ionization radiation and, probably, the increase in the diagnostic potential of the hematological service of the CO.

Extraction Processes

Propolis is a resinous substance collected by bees from plants and its natural product is available as a safe therapeutic option easily administered orally and readily available as a natural supplement and functional food. In this work, we review the most recent scientific evidence involving propolis from two countries (Brazil and Mexico) located in different hemispheres and with varied biomes. Brazil has a scientifically well documented classification of different types of propolis. Although propolis from Brazil and Mexico present varied compositions, they share compounds with recognized biological activities in different extraction processes. Gram-negative bacteria growth is inhibited with lower concentrations of different types of propolis extracts, regardless of origin. Prominent biological activities against cancer cells and fungi were verified in the different types of extracts evaluated. Antiprotozoal activity needs to be further evaluated for propolis of both origins. Regarding the contamination of propolis (e.g., pesticides, toxic metals), few studies have been carried out. However, there is evidence of chemical contamination in propolis by anthropological action. Studies demonstrate the versatility of using propolis in its different forms (extracts, products, etc.), but several potential applications that might improve the value of Brazilian and Mexican propolis should still be investigated.

We have investigated the spectrograms (dispersion: 8Å/mm) in the photographic infrared region fromλ7500 toλ9000 of some carbon stars obtained by the coudé spectrograph of the 74-inch reflector attached to the Okayama Astrophysical Observatory. The names of the stars investigated are listed in Table 1.

Good Agreement

For years the separation of carcinoma and sarcoma and the subclassification of sarcomas has been based on the appearance of the tumor cells and their microscopic growth pattern and information derived from certain histochemical and special stains. Although this method of study has produced good agreement among pathologists in the separation of carcinoma from sarcoma, it has given less uniform results in the subclassification of sarcomas. There remain examples of neoplasms of different histogenesis, the classification of which is questionable because of similar cytologic and growth patterns at the light microscopic level; i.e. amelanotic melanoma versus carcinoma and occasionally sarcoma, sarcomas with an epithelial pattern of growth simulating carcinoma, histologically similar mesenchymal tumors of different histogenesis (histiocytoma versus rhabdomyosarcoma, lytic osteogenic sarcoma versus rhabdomyosarcoma), and myxomatous mesenchymal tumors of diverse histogenesis (myxoid rhabdo and liposarcomas, cardiac myxoma, myxoid neurofibroma, etc.)

Degree Of Differentiation

With the extensive industrial use of asbestos in this century and the long latent period (20-50 years) between exposure and tumor presentation, the incidence of malignant mesothelioma is now increasing. Thus, surgical pathologists are more frequently faced with the dilemma of differentiating mesothelioma from metastatic adenocarcinoma and spindle-cell sarcoma involving serosal surfaces. Electron microscopy is amodality useful in clarifying this problem.In utilizing ultrastructural features in the diagnosis of mesothelioma, it is essential to appreciate that the classification of this tumor reflects a variety of morphologic forms of differing biologic behavior (Table 1). Furthermore, with the variable histology and degree of differentiation in mesotheliomas it might be expected that the ultrastructure of such tumors also reflects a range of cytological features. Such is the case.

Introduction: The analysis and interpretation of electron micrographs of cells and tissues, often requires the accurate extraction of structural networks, which either provide immediate 2D or 3D information, or from which the desired information can be inferred. The images of these structures contain lines and/or curves whose orientation, lengths, and intersections characterize the overall network.Some examples exist of studies that have been done in the analysis of networks of natural structures. In, Sebok and Roemer determine the complexity of nerve structures in an EM formed slide. Here the number of nodes that exist in the image describes how dense nerve fibers are in a particular region of the skin. Hildith proposes a network structural analysis algorithm for the automatic classification of chromosome spreads (type, relative size and orientation).
