Characteristics of hotel premises in Belgorod city

Hotel industry is regarded as one of the factors in the development of tourism and the initial basis for planning the production of the tourist product. It determines the specificity of the development of tourism, being the basis for the production of the tourism product in planning the priorities of the investment policy. The article presents the results of the authors’s research, as well as materials open print and electronic resources. The authors analyzed the state of hotel real estate market of Belgorod, the structure of the number of rooms, hotel occupancy assessed by type of rooms, highlighted promising areas of the hotel business. It should be noted, that the development of domestic tourism, the growth of business and cultural activity in the region will contribute to the further development of tourism infrastructure and, in particular, the hotel industryyesБелгородский государственный университе

The paper analyzes the data available in the literature on sentinel lymph node biopsy in patients with oral cancer and shows its advantages over prophylactic neck dissection: less pronounced functional and cosmetic consequences, the possibility of a detailed pathomorphological analysis of removed neck lymph nodes macrospecimens with immunohistochemical studies

The infrastructure of public catering in the context of tourist city space development

To assess the impact of environmental factors on the activities of catering enterprises of the Belgorod region and the quality of customer service, the authors proposed a method using STEP-analysis and SWOT-analysis. The analysis of environmental factors was carried out on the basis of the expert evaluation results conducted in two stage

Transformation of museum product

Today, each museum needs to develop an active strategy of market development, which is preceded by a comprehensive analysis of potential consumers of the museum product, on the basis of which the directions of development will be proposed. The conducted research allowed us to reveal a number of problems which are connected with necessity of transformation of the museum product providing satisfaction of visitor’s requirements and, at the same time, increase in the income of the museu

Properties of Neutral Charmed Mesons in Proton--Nucleus Interactions at 70 GeV

The results of treatment of data obtained in the SERP-E-184experiment "Investigation of mechanisms of the production of charmed particles in proton-nucleus interactions at 70 GeV and their decays" by irradiating the active target of the SVD-2 facility consisting of carbon, silicon, and lead plates, are presented. After separating a signal from the two-particle decay of neutral charmed mesons and estimating the cross section for charm production at a threshold energy {\sigma}(c\v{c})=7.1 \pm 2.4(stat.) \pm 1.4(syst.) \mub/nucleon, some properties of D mesons are investigated. These include the dependence of the cross section on the target mass number (its A dependence); the behavior of the differential cross sections d{\sigma}/dpt2 and d{\sigma}/dxF; and the dependence of the parameter {\alpha} on the kinematical variables xF, pt2, and plab. The experimental results in question are compared with predictions obtained on the basis of the FRITIOF7.02 code.Comment: 9 pages, 9 figures,3 table

PREOPERATIVE CHEMOTHERAPY FOR COLORECTAL CANCER LIVER METASTASES: SHORT-TERM RESULTS

Background. At present liver resection combined with chemotherapy is the only treatment for isolated resectable colorectal cancer liver metastases that potentially can achieve cure. Effective preoperative chemotherapy allows us to evaluate chemoresponsiveness of the tumor and increase metastases resectability.Materials and methods. Between 2006 and 2011, 60 patients with potentially resectable colorectal cancer liver metastases were included in the study. All patients received preoperative oxaliplatin- or irinotecan-based chemotherapy; average duration of treatment was 3.6 ± 0.11 months. Liver resection was performed after chemotherapy: 29 (48.3 %) pts underwent hemihepatectomy, 11 (18.3 %) pts – extended hemihepatectomy and 20 (33.4 %) pts – segmentectomy. Pathologic response in liver metastases was assessed to analyze efficacy of preoperative chemotherapy.Results. Objective response to preoperative chemotherapy was observed in 33 (55 %) pts. 23 (38.3 %) patients had stable disease. The maximum effect of preoperative chemotherapy was achieved in patients with bilobar liver metastases, receiving combination with oxaliplatin – in 23 (63.9 %) cases. Side effects of 334 cycles of preoperative chemotherapy were assessed. In most cases, adverse events were not clinically significant. Side effects of grade III/IV in 18 (5.4 %) cycles were observed in 12 (20 %) patients. 52 (86.7 %) patients underwent R0-resections; 8 pts had R1 (n = 5) и R2 (n = 3) resections of metastases. There were no postoperative deaths. Pathologic response was observed in 55/60 (91.7 %) cases: grade I was seen in 17 (28.3 %) cases; grade II – in 14 (23.3 %); grade III – in 20 (33.3 %) and grade IV – in 4 (6.8 %) cases. Pathologic response of grade III/IV occurred in 63.6 % patients with partial treatment response and 13 % pts – with stable disease (р = 0.01).Conclusions. Highest efficacy of preoperative chemotherapy in combined treatment of colorectal cancer was achieved in patients with bilobar liver metastases. Safety of two-component chemotherapy regimens was confirmed. This study presents significant correlation between preoperative chemotherapy efficacy and pathologic response in liver metastases

Amplicon metagenomics of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae) as a proxy for lemur (Primates, Lemuroidea) studies in Madagascar

Dung beetles (Scarabaeidae, Scarabaeinae) are among the most cost-effective and informative biodiversity indicator groups, conveying rich information about the status of habitats and faunas of an area. Yet their use for monitoring the mammal species, that are the main providers of the food for the dung beetles, has only recently been recognized. In the present work, we studied the diet of four endemic Madagascan dung beetles (Helictopleurus fissicollis (Fairmaire), H. giganteus (Harold), Nanos agaboides (Boucomont), and Epilissus splendidus Fairmaire) using high-throughput sequencing and amplicon metagenomics. For all beetle species, the ⅔–¾ of reads belonged to humans, suggesting that human feces are the main source of food for the beetles in the examined areas. The second most abundant were the reads of the cattle (Bos taurus Linnaeus). We also found lower but significant number of reads of six lemur species belonging to three genera. Our sampling localities agree well with the known ranges of these lemur species. The amplicon metagenomics method proved a promising tool for the lemur inventories in Madagascar
