    C-Met Activation Promotes Extravasation of Hepatocellular Carcinoma Cells Into 3d-Cultured Hepatocyte Cells in Lab-On Device
    (Elsevier, 2023) Solmaz, Gülhas; Bağcı, Gülsün; Çömez, Dehan; Topel, Hande; Yılmaz, Yeliz; Bağırsakçı, Ezgi; Güneş, Aysim; Batı Ayaz, Gizem; Tahmaz, İsmail; Bilgen, Müge; Pesen Okvur, Devrim
    Activation of c-Met signaling is associated with an aggressive phenotype and poor prognosis in hepatocellular carcinoma (HCC); however, its contribution to organ preference in metastasis remains unclear. In this study, using a Lab on a Chip device, we defined the role of aberrant c-Met activation in regulating the extravasation and homing capacity of HCC cells. Our studies showed that (i) c-Met overexpression and activation direct HCC cells preferentially towards the hepatocytes-enriched microenvironment, and (ii) blockage of c-Met phosphorylation by a small molecule inhibitor attenuated extravasation and homing capacity of HCC cells. These results, thus, demonstrate the role of c-Met signaling in regulating the colonization of HCC cells preferentially in the liver. © 2023 Elsevier B.V.

    Reply: the Effect of Primary Surgery in Patients With Stage Iv Breast Cancer With Bone Metastasis Only (protocol Bomet Mf 14-01): a Multi-Center, Registry Study
    (Springer, 2021) Soran, Atilla; Sezgin, Efe; Özbaş, Serdar; Doğan, Lütfi
    Dear Editor, We’d like to thank Drs. Ishizuka and Horimoto for their letter to the editor. We’re glad to see their interest to our prospective study. Regarding their recommendation that univariate Kaplan–Meier analysis does not eliminate confounding factors, such as age, tumor size, number of bone metastasis, etc., we employed propensity score methods for the results, including Fig. 1.

    Prof. Dr. O. Yavuz Ataman
    (TÜBİTAK, 2021) Eroğlu, Ahmet Emin
    Prof. Dr. O. Yavuz Ataman passed away on August 15, 2020, in Ankara. He was an academic as well as a social figure throughout his life. He had remarkable achievements in academy as a researcher, an educator, and an administrator. He was known for his unique approaches to the events in all aspects of life. With his beloved character, he was really special. With Prof. Ataman's passing away, the chemistry and especially analytical chemistry community have lost a very special member.

    A Characterization Study of Some Aspects of the Adsorption of Aqueous Co2+ Ions on a Natural Bentonite Clay
    (Elsevier Ltd., 2006) Shahwan, Talal; Erten, Hasan N.; Ünügür, S.
    The natural bentonite used in this study contained montmorillonite in addition to low cristobalite. The uptake of aqueous Co2+ ions was investigated as a function of time, concentration, and temperature. In addition, the change in the interlayer space of montmorillonite was analyzed using XRPD, and the distribution of fixed Co2+ ions on the heterogeneous clay surface was recorded using EDS mapping. The sorbed amount of Co2+ appeared to closely follow Freundlich isotherm, with the sorption process showing apparent endothermic behavior. The relevance of the apparent Δ Ho values is briefly discussed. Analysis of the Co-sorbed bentonite samples using SEM/EDS showed that the montmorillonite fraction in the mineral was more effective in Co2+ fixation than the cristobalite fraction. XRPD analysis demonstrated that the interlayer space of montmorillonite was slightly modified at the end of sorption.

    Rates of Myocardial Infarction and Coronary Artery Disease and Risk Factors in Patients Treated With Radiation Therapy for Early-Stage Breast Cancer
    (John Wiley and Sons Inc., 2007) Ural, Ali Uğur; Avcu, Ferit; Baran, Yusuf
    We read the interesting article by Jagsi et al on the increased rates of coronary artery disease in patients treated with radiation therapy for early-stage breast cancer.1 In their study, those authors concluded that the findings support further assessment of clinical outcomes when newer techniques of chemotherapy planning are employed as well as investigation of the potential role of innovative techniques. However, there was no mention of the novel radiosensitizing and chemosensitizing effects of bisphosphonates (BPs), which inhibit tumor cell adhesion to bone, and tumor growth in breast cancer.
