    In this article research the influence of natural montmorillonite containing sorbent used as a mineral supplement in animal feed in an amount of 30 g per 1 kg of sorbent feed on commercial quality table eggs at his dacha hens-layers. Found that feeding hens’ mineral feed additive reduces the toxic chemical elements in a chicken egg. It was found that the weight of the eggs in the experimental group compared to the control group, was significantly increased by 3,5% (p <0,05) after the completion of feeding the mineral sorbent. Despite the fact that in the control group, egg weight did not change and remained virtually unchange

    The research objective is in definition of the main tools participating in process of commercialization of grocery and marketing on the basis of expansion and deepening of the existing theory and methodology of commercialization, and also development of recommendations to improvement of tools that will promote finally to increase of efficiency of process of acceptance of a novelty by the market. Research is conducted on the basis of two-stage methodology including at the first stage carrying out questioning among the employees occupied in the course of commercialization in the large companies FMCG of the market, and at the second stage a case - research of two - players of the Russian market of juice. Confirmation of the made hypothesis that in most cases the innovations put on the market, can be considered grocery that is explainable that such innovations are capable to give to consumers essentially new advantages is result of research. The interrelation between stages of commercialization and the tools applied during this period is also confirmed. In the analysis of separate tools the tools informing the consumer on new products showed the greatest importance. Among them the special importance is played by TV advertizing. Practical application of results consists in identification tools for each of stages of commercialization of innovations the FMCG companies, and also those from them which play a paramount role on each of stages are defined.ИсслСдованиС ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½ΠΎ на основС двухэтапной ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠ»ΠΎΠ³ΠΈΠΈ, Π²ΠΊΠ»ΡŽΡ‡Π°ΡŽΡ‰Π΅ΠΉ Π½Π°Β ΠΏΠ΅Ρ€Π²ΠΎΠΌ этапС ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½ΠΈΠ΅ анкСтирования срСди сотрудников, занятых в процСссС ΠΊΠΎΠΌΠΌΠ΅Ρ€Ρ†ΠΈΠ°Π»ΠΈΠ·Π°Ρ†ΠΈΠΈ Π²Β ΠΊΡ€ΡƒΠΏΠ½Ρ‹Ρ… компаниях Π½Π°Β Ρ€Ρ‹Π½ΠΊΠ΅ FMCG, Π°Β Π½Π°Β Π²Ρ‚ΠΎΡ€ΠΎΠΌ этапС – исслСдованиС Π΄Π²ΡƒΡ… ΠΈΠ³Ρ€ΠΎΠΊΠΎΠ² российского Ρ€Ρ‹Π½ΠΊΠ° соков.ΠŸΠΎΠ΄Ρ‚Π²Π΅Ρ€ΠΆΠ΄Π΅Π½Π° Π³ΠΈΠΏΠΎΡ‚Π΅Π·Π° ΠΎΒ Ρ‚ΠΎΠΌ, Ρ‡Ρ‚ΠΎΒ Π²Β Π±ΠΎΠ»ΡŒΡˆΠΈΠ½ΡΡ‚Π²Π΅ случаСв ΠΈΠ½Π½ΠΎΠ²Π°Ρ†ΠΈΠΈ ΠΌΠΎΠ³ΡƒΡ‚ ΡΡ‡ΠΈΡ‚Π°Ρ‚ΡŒΡΡ ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ‚ΠΎΠ²Ρ‹ΠΌΠΈ, ΠΏΠΎΡΠΊΠΎΠ»ΡŒΠΊΡƒ ΠΈΠΌΠ΅ΡŽΡ‚ ΠΏΡ€ΠΈΠ½Ρ†ΠΈΠΏΠΈΠ°Π»ΡŒΠ½ΠΎ Π½ΠΎΠ²Ρ‹Π΅ прСимущСства для потрСбитСлСй.

    Research into in-service deterioration of ball-rolling rolls

    Full text link
    This work features research findings on causes of deterioration occurring in ball-rolling rolls. The causes of such deterioration may originate not only in the excessive loads application and the use of bottleneck operating parameters but also in the specific process being implemented and the equipment used to heat-treat the rolling rolls. The deterioration occurring in roll flanges having a relatively small thickness was used to demonstrate that, to prevent the deterioration of ball-rolling roll flanges, the mill design must accommodate the minimum allowable flange widths obtained as a function of maximum allowable loads and the roll pass calculations. The next example of roll deterioration involved the use of a gas furnace to implement the heating stage of the quench hardening process for rolls made of 35KhGSA steel, which, as a result, developed roll deterioration. The use of rolls of the same steel grade, which were heat-treated in an arc furnace prior to being quenched, has been shown to deliver long-lasting positive results evidenced by many years of their operation. Rolls made of 5KhNM steel have also been shown to respond well to the heat treatment preceding the quenching process, but this time, the treatment was implemented in a gas furnace.

    Background: The study assessed the possibility of dividing patients into groups based on the assessment of morphological changes in the epithelium of small-caliber bronchi located near the primary tumor in order to predict high and low risks of distant metastasis of non-small cell lung cancer. Methods: In 171 patients with non-small cell lung cancer (T1-4N0-3M0) in small-caliber bronchi taken at a distance of 3–5 cm from the tumor, various variants of morphological changes in the bronchial epithelium (basal cell hyperplasia (BCH), squamous cell metaplasia (SM), and dysplasia (D)) were assessed. Long-term results of treatment, namely, distant metastasis, were assessed after 2 and 5 years. Results: During the follow-up period, distant metastases were found in 35.1% (60/171) of patients. Most often, they were observed in patients of the high-risk group: BCH+SMβˆ’Dβˆ’(51.6%, 40/95) and BCHβˆ’SM+D+ (54.4%, 6/11). Less often, distant metastases were observed in low-risk group patients: BCH+SM+Dβˆ’ (6.7%, 3/45) and BCHβˆ’SMβˆ’Dβˆ’(10.0%, 2/20). Tumor size, grade, and stage were significant predictors of metastasis only in the high-risk group. The 5-year metastasis-free survival was better in the low-risk group of distant metastases. Conclusions: Isolated BCH or dysplasia in small bronchi distant from foci of tumor isassociated with a high-risk distant metastasis and less 5-year metastasis-free survival

    The purpose of the study: to evaluate the effectiveness of postoperative management of the bronchial stump in lung cancer patients. material and methods. Forty-four patients with stage III lung cancer underwent endoscopic examination of the bronchial tree 3, 6, 9 and 12 months after surgery. The EVIS EXERAII and LUCERA videoendoscopic complexes with consistent use of white light mode, autofluorescence and narrow- spectrum mode were used. Endoscopic results were compared with morphological findings. Results. X-ray of the chest was negative for tumor recurrence in 3 (6.8 %) cases and early metachronous tumor of the trachea was revealed in 1 (2.3 %) case. The main endoscopic symptoms of early local recurrence in the bronchial stump were the marked lilac glow identified in the AFI mode and the mucosal vascular pattern deformation Timely diagnosis of recurrence allows a special treatment to be performed.ЦСль исслСдования - ΠΎΡ†Π΅Π½ΠΊΠ° эффСктивности комплСксного послСопСрационного ΠΌΠΎΠ½ΠΈΡ‚ΠΎΡ€ΠΈΠ½Π³Π° состояния ΠΊΡƒΠ»ΡŒΡ‚ΠΈ ΠΎΠΏΠ΅Ρ€ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ Π±Ρ€ΠΎΠ½Ρ…Π° Ρƒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Ρ€Π°ΠΊΠΎΠΌ Π»Π΅Π³ΠΊΠΎΠ³ΠΎ.

    The data on modern views on the problem of pre-cancerous changes (epithelial hyperplasia, squamous metaplasia, preneoplasia (dysplasia I) and neoplasia (dysplasia II-III) when squamous cell cancer and adenocarcinoma of the lung are summarizes in the present review. Atypical adenomatous hyperplasia, which is considered precancerous process for adenocarcinoma of the lung, due to the rare occurrence in the review is not considered. The attention is focused on the classification of morphological characteristics of precancerous changes in respiratory epithelium. The analysis of frequency and reversibility of preand neoplastic changes in bronchial epithelium. We discuss the connection between the nature of the changes of respiratory epithelium in the bronchi, developing simultaneously with squamous cell cancer or adenocarcinoma of the lung, with tumour progression.Научно-ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Ρ‚Π΅Π»ΡŒΡΠΊΠΈΠΉ институт ΠΎΠ½ΠΊΠΎΠ»ΠΎΠ³ΠΈΠΈ Бибирского отдСлСния РАМН, Вомск, ΠΠ°Ρ†ΠΈΠΎΠ½Π°Π»ΡŒΠ½Ρ‹ΠΉ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Ρ‚Π΅Π»ΡŒΡΠΊΠΈΠΉ Вомский государствСнный унивСрситСт, ВомскВ настоящСм ΠΎΠ±Π·ΠΎΡ€Π΅ ΠΎΠ±ΠΎΠ±Ρ‰Π΅Π½Ρ‹ Π΄Π°Π½Π½Ρ‹Π΅ ΠΎ соврСмСнных взглядах Π½Π° ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΡƒ ΠΏΡ€Π΅Π΄Ρ€Π°ΠΊΠΎΠ²Ρ‹Ρ… ΠΈΠ·ΠΌΠ΅Π½Π΅Π½ΠΈΠΉ (ΡΠΏΠΈΡ‚Π΅Π»ΠΈΠ°Π»ΡŒΠ½Π°Ρ гипСрплазия, плоскоклСточная мСтаплазия, прСнСоплазия (дисплазия I стСпСни) ΠΈ нСоплазия (дисплазии II–III стСпСни)) ΠΏΡ€ΠΈ плоскоклСточном Ρ€Π°ΠΊΠ΅ ΠΈ Π°Π΄Π΅Π½ΠΎΠΊΠ°Ρ€Ρ†ΠΈΠ½ΠΎΠΌΠ΅ Π»Π΅Π³ΠΊΠΎΠ³ΠΎ.

    The mechanism of the relationship between pretumor changes in the bronchial respiratory epithelium and the risk of progression of non-small cell lung cancer (NSCLC) remains unclear. It has been suggested that the relationship between reactive changes in the bronchial mucosa and NSCLC progression may be caused by the functional status of monocytic-macrophage cells as important participants in infammation, which determines both the risk of premalignant changes in the epithelium and malignant progression. The purpose of the study was to investigate the phenotypic profle of peripheral blood monocytes and macrophages induced from monocytes in vitro depending on the state of respiratory epithelium in NSCLC patients. Material and Methods. The study included 39 patients with newly diagnosed NSCLC. Based on the morphological examination of small bronchi taken at the distance of 3–5 cm from the tumor, patients were divided into the following groups depending on the type of pretumor changes: no pretumor changes (n=6), isolated basal cell hyperplasia (BCH) (n=13), combination of BCH and squamous metaplasia (SM) (n=3), combination of unchanged epithelium and focal BCH (n=17). The phenotypic features of peripheral blood monocytes and in vitro-induced macrophages were assessed before treatment using fow cytometry. Results. The state of the respiratory epithelium in NSCLC patients prior to the start of anticancer treatment was associated with the phenotypic features of peripheral blood monocytes, but not with the profle of macrophages induced from them. Distortion of the response of induced macrophages to the polarizing stimuli was observed in NSCLC patients: the cultured cells responded to both M1 and M2 inducers (LPS and IL-4, respectively) with a phenotype shift to M2, while the CD206 marker expression varied depending on the presence and type of pretumor changes. Conclusion. The phenotypic profle of peripheral blood monocytes was associated with the state of the respiratory epithelium in NSCLC patients before anti-tumor treatment, but not with the phenotypic features of induced macrophages.ΠœΠ΅Ρ…Π°Π½ΠΈΠ·ΠΌ взаимосвязи ΠΏΡ€Π΅Π΄ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅Π²Ρ‹Ρ… ΠΈΠ·ΠΌΠ΅Π½Π΅Π½ΠΈΠΉ Π² рСспираторном эпитСлии Π±Ρ€ΠΎΠ½Ρ…ΠΎΠ² с риском прогрСссирования Π½Π΅ΠΌΠ΅Π»ΠΊΠΎΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½ΠΎΠ³ΠΎ Ρ€Π°ΠΊΠ° Π»Π΅Π³ΠΊΠΎΠ³ΠΎ (ΠΠœΠ Π›) остаСтся нСясным.
