Wettability of Nanostructured Surfaces

There are many studies in literature concerning contact angle measurements on different materials/substrates. It is documented that textiles can be coated with multifunctional materials in form of thin films or nanoparticles to acquire characteristics that can improve the protection and comfort of the wearer. The capacity of oxide nanostructures to inhibit fungal development and neutralize bacteria is a direct consequence of their wetting behavior [1–6]. Moreover, the radical modification of wetting behavior of nanostructures from hydrophilic to hydrophobic when changing the pulsed laser deposition (PLD) ambient will be thoroughly discussed

Analysis of survival after radical surgery for stomach cancer in odessa regional cancer center

The survival of patients with the locally advanced stage of stomach cancer (SC), who underwent various variants of preventive lymphatic nodes dissection, was considered. The survival of patients was compared with the stage and T, N indexes. Lymphadenectomy D2 were effective and increased cumulative survival in patient`s group T4aNoMo, stage IIB and T4aN1Mo, stage III A, and in groups of patients where D2 lymphadenectomy were ineffective - T4bNoMo, stage ІІІB, T4bN1Мo, stage ІІІB and T4aN2Мo, stage IIIB. D2 were more efficient operation in the case of tumor serosa invasion and invasion to the peritoneal cavity (SE) in the absence of multiple metastases to the regional lymph nodes (N1 according to the 7th revision of the classification - 1-2 metastatic lymph nodes), and when the tumor infiltrated the surrounding organs (SI) and the presence of multiple regional metastases, D2 lymphodissection did not gave positive results, comparising with D1

Significance of basic clinical tests changing after the Hypec procedure in patients with gastric cancer and some other tumors

Hyperthermic intraperitoneal chemotherapy is a popular method of palliative treatment in patients with malignant abdominal tumors. This review is devoted to trace changes in general clinical tests in patients with carcinomatosis. The patients were operated on at the Clinic of Reconstructive and Plastic Medicine of the Odessa National Medical University. All patients satisfactorily tolerated this procedure. The object of the study was to track those changes with patients that took place in the immediate (prior to discharge) postoperative period. 25 patients have recruited to the study. In the group changes in 11 basic clinical and laboratory parameters among those included were monitored in the study. Hemoglobin, leukocytes, platelets, total protein, bilirubin, serum glucose concentration, liver enzymes alanine aminotransferase and aspartate aminotransferase levels, thymol test and coagulogram indices. Thus, the most significant indicators, such as the concentration of hemoglobin, leukocytes and platelets, have not undergone significant changes after HIPEC. Hemoglobin decreased by 6 units (g / l), the concentration of leukocytes, on the contrary, increased by 2 units (T/l), platelet levels dropped by 61 units (also G/l). The concentration of total protein decreased by 7 units. The concentration of total bilirubin practically did not change, decreasing by about 1 unit. Indicators of AST and ALT did not increase, decreasing by 8 and 3 units, respectively. The average concentration value of blood glucose level slightly increased by almost 1 unit. Thymol levels have not changed. The prothrombin index decreased by 3 units; the concentration of fibrinogen in serum remained at approximately the same level. HIPEC procedure does not significantly affect the clinical and laboratory parameters. However, the tendency of this category of patients to hypercoagulation, hypoproteinemia and hyperglucosemia was noted

Evaluation advanced lymph node dissection impact on long-term survival rate of gastric cancer patients. Journal of Education

Over a period of 2007-2011 188 stomach cancer (SC) patients have been included in the research in abdominal oncosurgical department of Odessa regional oncological dispensary. It was retrospective, one-center, nonrandomized research. Volume of lymph node dissections differed by quantity of lymph nodes to be removed. All patients were divided into three groups. Patients with D1 or D1+ lymph node dissections have been performed, totally 90 patients are included in group of historical control. The main group includes 33 patients to whom D3 lymph node dissections is executed and, finally, control group – 65 patients dissected up to the D2 volume. In all cases so-called lymph node dissections for principal reasons have been executed. The multifactorial analysis of patients survival is implemented depending on a type of a lymph node dissections, a stage of the cancer, number of involved lymph nodes, involvement of the tumoral microcirculatory net (ly is carried out, v) signs of a perinevral invasion (Nev), availability of residual tumoral tissue (R), degree of a differentiation (G). Regardless of a disease stage, SC at 60% of patients, represented with initially hematologicaly disseminated disease. 40% of SC`s had no signs of intratumoral microcirculatory net involvement even in case of more than 15 regional lymph nodes are involved. In the absence of a SC perinevral invasion appeared to be the most precise predictive marker. The conclusion is made some brand new additional53 prognostic factors could play a crucial role in more accurate patients selection for expanded lymph node dissections

Lymph node dissection impact on long-term survival rate of gastric cancer patients in Ukraine

The original formula for predicting the survival of gastric cancer patients undergoing surgical treatment

The purpose of this work was to find ways to predict the survival of gastric cancer patients. The study included 221 patients who were radically operated in the abdominal department of the Odessa Regional Oncology Center from 2007 to 2013. The life expectancy of this group of patients was measured in months. From the factors given in the article, only the age of the patient, the presence and invasion in neighboring organs and the number of organs resected during the operation were those factors that had a significant impact on the prognosis. A formula was obtained for the formal evaluation of the duration of patients. The results are preliminary. Conclusions. As a result of the regression analysis, a polynomial (formula) was obtained, which can be used to predict the survival of patients who underwent surgery for gastric cancer. There is a need to create clearer gradations of survival dependencies of cancer patients from different clinical and morphological situations. A mathematical apparatus with many variables can be used to create similar models for the analysis of survival in other types of pathology

Some novel ways of gastric cancer patients treatment personification

In this paper the authors perform the analysis of molecular and morphological factors influencing the survival of patients with gastric cancer (n = 221). They analyzed the survival rate in this group of patients based on the analysis of molecular markers VEGFR, p53, Her2, Ki-67. Measured role in the survival such factors as the degree of differentiation of primary gastric tumors, the presence of microscopic tumor involvement of perineural and perivascular spaces, the degree of invasion to gastric wall by T1 = 1 and to T4a = 4, T4b = 5, number of regional lymph nodes affected by metastasis, and other factors. As an arbitrator used survival curves calculated by the method of R. J. Cox, time of lifespan, measured in months, as well as a comparison of the areas under the curves of survival

Novel data according Will Roger`s phenomenon in stomach cancer patients

Mostly Will Roger`s phenomenon means existence of so-called "jumping" or "jumping over the stages" regional metastases in the stomach cancer patients. N1 in the 6th edition means 16 regional lymph nodes involvement, while the N1 seventh edition – only 1-2 of regional lymph nodes involvement. This means that T1N1Mo \ 6th and T1N1Mo \ 7th - not quite the same, and the survival of the two groups will be different. The study, made on the abdominal oncosurgical department of Odessa Regional Oncology Center, included 188 patients operated for gastric cancer in the period 2007-2011. The study included only radically treated patients. Comparison of survival in patients with gastric cancer between 6th revision groups of 7th has been reviewed. The classification mission is to provide differences in the survival rates between the groups. Regression multivariate Cox analysis showed that 7th UICC classification showed different capability of stratifying survival groups of UICC N classification (P \ 0.01)

Rapidity and centrality dependence of particle production for identified hadrons in Cu+Cu collisions at sNN=200\sqrt{s_{NN}} = 200 GeV

The BRAHMS collaboration has measured transverse momentum spectra of pions, kaons, protons and antiprotons at rapidities 0 and 3 for Cu+Cu collisions at $\sqrt{s_{NN}} = 200$ GeV. As the collisions become more central the collective radial flow increases while the temperature of kinetic freeze-out decreases. The temperature is lower and the radial flow weaker at forward rapidity. Pion and kaon yields with transverse momenta between 1.5 and 2.5 GeV/c are suppressed for central collisions relative to scaled $p+p$ collisions. This suppression, which increases as the collisions become more central is consistent with jet quenching models and is also present with comparable magnitude at forward rapidity. At such rapidities initial state effects may also be present and persistence of the meson suppression to high rapidity may reflect a combination of jet quenching and nuclear shadowing. The ratio of protons to mesons increases as the collisions become more central and is largest at forward rapidities.Comment: 19 pages, 11 figures and 6 table

Measurement of shower development and its Moli\`ere radius with a four-plane LumiCal test set-up

A prototype of a luminometer, designed for a future e+e- collider detector, and consisting at present of a four-plane module, was tested in the CERN PS accelerator T9 beam. The objective of this beam test was to demonstrate a multi-plane tungsten/silicon operation, to study the development of the electromagnetic shower and to compare it with MC simulations. The Moli\`ere radius has been determined to be 24.0 +/- 0.6 (stat.) +/- 1.5 (syst.) mm using a parametrization of the shower shape. Very good agreement was found between data and a detailed Geant4 simulation.Comment: Paper published in Eur. Phys. J., includes 25 figures and 3 Table
