The main driving force of osseointegration on titanium implants is believed to be the calcification caused by cellular activity. However, owing to the opacity of bulk titanium, live cells on titanium surfaces cannot be observed using an inverted microscope. [https://www.selleckchem.com/products/AZD7762.html AZD7762 solubility dmso] To overcome this limitation, this study proposes a transparent titanium thin layer as a simulated titanium surface that allows live-cell observation from below. The titanium layer was fabricated on a polystyrene culture dish by magnetron DC sputtering using a pure Ti(JIS1) target. The titanium layer was characterized by transparency, composition, structure, and wettability. Osteoblast-like cells were cultured in the titanium-coated dishes. The cell culture was observed periodically using an inverted microscope, and the images were compiled into time-lapse videos. Cells on the titanium layer were characterized by movement speeds and doubling times. The titanium-coated dish was transparent gray, and its transmittance profile was consistent with that of the polystyrene dish. The titanium layer showed similarities to bulk titanium surfaces in terms of composition and structure; that is, it showed an oxidized titanium outermost layer and titanium metal basal layer. The wettability of the titanium layer was hydrophilic with mean contact angles of 67.52°. Osteoblast-like cells successfully adhered to the titanium layer and proliferated to confluence. The time-lapse videos demonstrated active movement of the cells on the titanium layer, which suggested the involvement of the titanium surface in cellular motility. The cell culture on the titanium layer can be considered cell culture on a titanium surface. In short, the titanium layer enabled the acquisition of information for living cells on titanium that has either been unknown or analogically understood based on cell culture on polystyrene dishes.Cervical cancer is a common female cancer. It is strongly associated with human papillomavirus (HPV) infection. However, HPV infection alone is not sufficient to induce cervical cancer because its development is dependent on the coexistence of several factors that enable the virus to overcome the host immune system. These include individual genetic background, environmental factors, or diet, including dietary selenium intake. Selenium is an essential trace element with antiviral properties and has been shown to exert antitumor effects. Surprisingly, the role of selenium in cervical cancer has not been studied as intensively as in other cancers. Here, we have summarized the existing experimental data on selenium and cervical cancer. It may be helpful in evaluating the role of this nutrient in treatment of the mentioned malignancy as well as in planning further studies in this area.The goal of this study was to mechanistically analyze the effects of pre-treatment or post-treatment melatonin on the metastatic spread in a mice model. Consequently, the effects on the tumor growth, angiogenesis and metastasis were evaluated with immunohistochemical and western blot analysis. 8-10 weeks-old female BALB/c mice (n = 60, 10/group) were used. Liver metastatic cells (4TLM) from 4T1 murine breast carcinoma were previously isolated. Melatonin was administrated either before or after the injection of 4TLM cells into the mammary pad. Tumor and vehicle (%6 ethanol) injections were given to vehicle groups. Tumor group consisted of the mice injected with only 4TLM cells injected to tumor group and no intervention to control group. Necropsies were performed 27 days after injection of 4TLM. Primary tumors and metastatic tissues were removed. Furthermore, changes in lung and liver metastasis and primary tumor growth and angiogenesis were evaluated. In our study neutrophil levels were noted to be increased in peripheral blood of the tumor-bearing mice. Melatonin exerted inhibitory effects on the 4TLM-induced leukocytosis. Melatonin significantly decreased lung and liver metastasis, primary tumor growth and angiogenesis. The results demonstrated that melatonin might have a therapeutic role through reducing systemic inflammatory responses, metastasis, tumor growth and angiogenesis.Undergoing bariatric surgery is a life-changing experience for adolescents. However, little is known about post-bariatric surgery management among Israeli adolescents. We aimed to identify the post-operative needs and support from a qualitative aspect. Seventeen adolescents who underwent bariatric surgery were interviewed by semi-structure telephone interview. The interview guide was validated by 10 content experts from different hospitals across the country. Data were collected in 2018. Analysis of the interviews revealed three major themes "multi-disciplinary team management," "patient satisfaction," and "follow-up." The "multi-disciplinary team management" theme was further divided into three major categories "pain management," "physiotherapy," and "nutrition." "Patient satisfaction" was further divided into "guidance" and "team handling" categories. The "follow-up" theme included recommendations for improvement. The analysis provides novel information about adolescents' needs after bariatric surgery. Healthcare professionals' awareness of the adolescents' perspective could contribute to providing optimal post-operative care to this population.<br /><br /> Hexagonal boron nitride nanoparticles (hBN NPs) are encouraging nanomaterials with unique chemical properties in medicine and biomedical fields. Until now, the optimal hBN NP's dosage and biochemical mechanism that can be used for in vivo systems has not been fully revealed. The main aim of this article is to reveal characteristics, serum and tissue interactions and any acute cytotoxic effect of different dose of hBN NPs for the first time.<br /><br /> hBN NPs at concentrations varying between 50-3200 µg/kg was administered by intravenous injection to Wistar albino rats (n = 80) divided into seven dosage and control groups. Blood and tissue samples were taken after 24 hours.<br /><br /> Our findings suggested that higher doses hBN NPs caused oxidative stress on the serum of rats dose-dependently. However, hBN NPs did not affect thiol/disulfide homeostasis on kidney, liver, spleen, pancreas and heart tissue of rats. Furthermore, hBN NPs increased serum disulfide formation by disrupting the thiol/disulfide balance in rats. Also, LOOH and MPO levels increased at high doses, while CAT levels decreased statistically.
