    Evaluating Ethanol Concentrations Against Staphylococcus Spp: a Proposal for Improving Nosocomial Bacteria Control
    (Elsevier, 2024) Soyer, Ferda; Özdemir, Özgün Öykü; Polat, Bengi; Ekenel, Nil Hazal
    Dear Editor, Nosocomial infections originating from commonly encountered pathogenic bacteria, notably Staphylococcus species, persist as a prominent global public health issue. This phenomenon exerts consequential impacts on both the well-being of patients and the healthcare personnel within hospital environments. Hospital-acquired infections from common bacteria like Staphylococcus remain a global public health concern. The European Centre for Disease Prevention and Control reports prevalence rates of 4.5% in the USA and 7.1% in Europe [1]. An estimated 8.9 million healthcare-associated infections occur annually in European hospitals and long-term care facilities [1]. According to the World Health Organization, although 10% of patients get healthcare-associated infections, at least a 30% reduction can be achieved through adequate infection prevention and control [2]. The efficacy of disinfection methodologies employed in healthcare institutions assumes critical significance in mitigating this threat.

    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.

    A Call for Benchmark Data in Mass Spectrometry-Based Proteomics
    (Proteomass Scientific Society, 2012) Allmer, Jens
    Proteomics is a quickly developing field. New and better mass spectrometers, the platform of choice in proteomics, are being introduced frequently. New algorithms for the analysis of mass spectrometric data and assignment of amino acid sequence to tandem mass spectra are also presented on a frequent basis. Unfortunately, the best application area for these algorithms cannot be established at the moment. Furthermore, even the accuracy of the algorithms and their relative performance cannot be established. This is due to the lack of proper benchmark data. This letter first introduces the field of mass spectrometry-based proteomics and then defines the expectations of a well-designed benchmark dataset. Thereafter, the current situation is compared to this ideal. A call for the creation of a proper benchmark dataset is then placed and it is explained how measurement should be performed. Finally, the benefits for the research community are highlighted. © 2012, Proteomass Scientific Society. All rights reserved.

    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.
