Introduction: Breast cancer is one of the most common types of cancer in the world and the treatments are being improved day by day. Although chemotherapy agents have begun to be used, side effects, resistance development and toxicity seen with these drugs are still steps that limit treatment. Objective: Our aim in this study is to show whether sodium selenate (NaS), which has different effects on many different cells, has antiproliferative and apoptotic effects on MCF-7 breast cancer cells, considering the dose-time relationship, and to reveal its effect on oxidant stress parameters. Methods: 10, 20, 30, 40 and 50 μM sodium selenate was applied to the cells for 24, 48 and 72 hours. MTT test was applied to show the proliferative effect. Apoptosis was also measured with Annexin V/7AAD in MCF7 cells. Malondaldehyde (MDA) and Glutathione (GSH) levels were studied to reveal the oxidant/antioxidant balance. Results: It has been shown that as the NaS dose increases in MCF-7 cells, cell viability decreases (p 0.05), but at all subsequent increasing NaS doses, viability was found statistically significant decreased (p: 0.001, p 0.05, respectively). Conclusion: Considering that NaS has an antitumor effect on breast cancer, increases oxidative stress and increases apoptosis by supressing the antioxidant protection system, and does not have a toxic effect on normal body cells at certain doses. When all these features evaluated, we think, selenium should be considered as a natural option in the treatment of breast cancer.

Background: This study aimed to evaluate the diagnostic value of interferon-γ release assay (IGRA), a sensitive microbiological diagnostic method, in children and adolescents with suspected tuberculosis in a country with a high burden of tuberculosis. Method: This study included 581 children and adolescents aged 4 - 19 years who were suspected of having tuberculosis, were latently infected with Mycobacterium tuberculosis, and had received at least one dose of BCG vaccine between April 17, 2019, and February 24, 2021. The study evaluated the TST results of 106 patients who had a positive Quantiferon test and were suspected of having tuberculosis. Results: The study included 581 patients aged between 4 and 19 years. Of these, 106 patients tested positive for the Quantiferon test, while 19 were indeterminate and 456 were negative. The Quantiferon test positivity rate was 18.24%. Among the 106 QFT-Plus-positive cases, 23 patients also tested positive for TST. The difference in distribution was found to be statistically significant. Conclusion: The QFT-Plus test is considered an alternative to TST and other microbiological diagnostic methods for early tuberculosis diagnosis, particularly in children and adolescents.

Bed-to-surface heat transfer experiments from a vertically submerged cylindrical surface were conducted in laboratory-scale (Dc = 25 cm) conical spouted and spout–fluid beds at two different conical angles (31° and 66°) in the high particle density range (2500 kg/m3 ≤ρp ≤ 6000 kg/m3). The effects of the bed design parameters (conical angle and inlet diameter of spouting gas entrance) and operating conditions (static bed height, particle size, density, and spouting and fluidization gas flow rates) on the heat transfer characteristics were investigated in detail. The heat transfer coefficients were shown to be dependent on the density and size of the particles. The minimum stable spouting velocities of the denser and larger particles were higher, which led to higher operational spouting velocities and thereby resulted in higher heat transfer coefficients. The positive effect of increasing the particle diameter on heat transfer was more pronounced in the spout and at the spout–annulus interface, whereas this effect was diminished in the annulus region. The heat transfer coefficient increased with increasing spouting gas velocity up to 1.0Ums–1.1Ums, beyond which no significant change was observed regardless of the particle type. The heat transfer coefficient in the annulus decreased with increasing conical angle because of reduced particle circulation. The spout–fluid operation increased the heat transfer coefficient by a maximum of 10% at the expense of a significant increase of the total gas flow rate. This result was attributed to the inability of the fluidizing gas to penetrate the annulus. An empirical correlation for the average heat transfer coefficient in the annulus was also proposed based on the data obtained in this work.
