Abstract
Biobanks are important infrastructures facilitating biomedical research. After a decade of rolling out such infrastructures, a shift in attention to the sustainability of biobanks could be observed in recent years. In this regard, an increase in the as yet relatively low utilisation rates of biobanks has been formulated as a goal. Higher utilisation rates can only be achieved if the perspectives of potential users of biobanks-particularly researchers not yet collaborating with biobanks-are adequately considered. To better understand their perspectives, a survey was conducted at ten different research institutions in Germany hosting a centralised biobank. The survey targeted potential users of biobank services, i.e. researchers working with biosamples. It addressed the general demand for biosamples, strategies for biosample acquisition/storage and reasons for/against collaborating with biobanks. In total, 354 researchers filled out the survey. Most interestingly, only a minority of researchers (12%) acquired their biosamples via biobanks. Of the respondents not collaborating with biobanks on sample acquisition, around half were not aware of the (services of the) respective local biobank. Those who actively decided against acquiring biosamples via a biobank provided different reasons. Most commonly, respondents stated that the biosamples required were not available, the costs were too high and information about the available biosamples was not readily accessible. Biobanks can draw many lessons from the results of the survey. Particularly, external communication and outreach should be improved. Additionally, biobanks might have to reassess whether their particular collection strategies are adequately aligned with local researchers' needs.

Abstract
OBJECTIVES In the past decade cancer, including head and neck squamous cell cancer (HNSCC), is increasingly being regarded as a stem cell associated disease which arises from cells with the property of stemness. According to the cancer stem cell (CSC) theory, only a specific subpopulation of cancer cells has the ability to initiate and perpetuate cancer growth, especially under treatment. In this article we describe a subpopulation of cells within HNSCC that expresses the stemness factor Oct-4, which leads to apoptotic resistance after exposure to chemotherapeutic agents. MATERIALS AND METHODS Permanent cell lines and HNSCC tissue were analyzed for expression of stem cell markers using flow cytometric, immunohistochemical approaches and an antibody based protein array. Chemotherapeutic agent-induced growth inhibition, also known as "enrichment", was determined by the colorimetric cell proliferation assay (MTT-based) and putative stem cell markers were investigated by flow cytometry. RESULTS Various potential CSC markers were identified in heterogenic expression profiles in permanent cell lines and solid tumors. Our data suggest the Oct-4A isoform as a marker of stemness in HNSCC and the enrichment of cancer stem-like cells by various chemotherapeutic agents was associated with a significantly higher expression of Oct-4. CONCLUSION This data suggests that many potential CSC markers are expressed on different expression levels in HNSCC. Among these markers Oct-4(A) plays a pivotal role in the detection of cancer cells with enhanced chemoresistance and provide evidence for the existence of cancer stem-like cells in HNSCC.

Abstract
BACKGROUND Radiation and systemic chemotherapy are standard treatment strategies for advanced or metastatic head and neck cancer. However, little is known about the implications and changes in the tumor microenvironment, including the T-helper (TH)1/TH2 balance in response to these treatment regimens. The aim of the current study was to unravel the effects of chemotherapeutic drugs and radiation on cytokine changes. MATERIALS AND METHODS In this study, the effect of radiation and chemotherapeutic treatment (5-fluorouracil and cisplatin) on eight cell lines was determined. Before and after exposure, cytokine levels in culture supernatants of cell lines were evaluated using the Bio-Plex Assay (Bio-Rad) and the Human TH1/TH2 Cytometric Bead Array (Becton Dickinson). Results were correlated with parallel measurements for cellular proliferation assessed by cytotoxicity assay. RESULTS Seven out of eight cell lines of primary tumors or metastases demonstrated an enhanced level of the cytokines interleukin (IL)-1β, IL-6, IL-8, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor-α (TNF-α), after sub-lethal radiation doses. Under treatment with low concentrations of 5-fluorouracil and cisplatin, all examined cell lines showed an increasing secretion of the cytokines IL-6 and G-CSF. In contrast, sub-lethal doses of both cytostatic drugs revealed a dose-dependent decrease in secretion IL-1β. Regarding GM-CSF and TNF-α, we demonstrated an increase in secretion by the primary tumors under low doses of 5-fluorouracil and cisplatin, whereas the metastases showed a sharp drop of GM-CSF and TNF-α secretion. Chemotherapeutic treatment led to no changes of the IL-8 cytokine profile. CONCLUSION The results suggest complex cytokine changes of the tumor microenvironment and more aberrant expression profiles under treatment with radiation and the chemotherapeutic drugs 5-fluorouracil and cisplatin.

Abstract
Using bioinformatics tools, we searched the predicted Theileria annulata and T. parva proteomes for putative schizont surface proteins. This led to the identification of gp34, a GPI-anchored protein that is stage-specifically expressed by schizonts of both Theileria species and is downregulated upon induction of merogony. Transfection experiments in HeLa cells showed that the gp34 signal peptide and GPI anchor signal are also functional in higher eukaryotes. Epitope-tagged Tp-gp34, but not Ta-gp34, expressed in the cytosol of COS-7 cells was found to localise to the central spindle and midbody. Overexpression of Tp-gp34 and Ta-gp34 induced cytokinetic defects and resulted in accumulation of binucleated cells. These findings suggest that gp34 could contribute to important parasite–host interactions during host cell division.
