Abstract
BACKGROUND The objective of this study is to develop and validate a specific screening instrument for assessing the quality of life (QoL) of patients with orofacial clefts. The Cleft-Screen-Questionnaire (CSQ) aims at identifying the main problematic areas and is intended for the routine use in everyday clinical practice to constantly evaluate the conditions' and treatments' effects on patients' well-being. METHODS First, a pool of 58 questions is created by collecting items from validated questionnaires previously used for assessing the QoL in cleft populations. After the removal of duplicate questions, the questionnaires are answered by 152 patients from a tertiary care center. A factor analysis followed by the calculation of Cronbach's alpha as a reliability measurement led to the final CSQ presented here. RESULTS The applied factor analysis resulted in five factors. Items showing low factor loadings (seen as <0.5) were excluded initially. Accordingly, factor analysis led to a preliminary number of 43 items. A reliability analysis using Cronbach's alpha and corrected alpha if item deleted showed an overall moderate to high reliability (seen as: 0.6-0.9). After excluding questions with increasing alphas if item deleted, analyses yielded in a final number of 38 questions. CONCLUSION The final 38-item CSQ is a reliable instrument for evaluating the health-related QoL of cleft patients.

Abstract
Systemic toxicity and tumor cell resistance still limit the efficacy of chemotherapy in colorectal cancer. Therefore, alternative treatments are desperately needed. The thiazolide Nitazoxanide (NTZ) is an FDA-approved drug for the treatment of parasite-mediated infectious diarrhea with a favorable safety profile. Interestingly, NTZ and the thiazolide RM4819-its bromo-derivative lacking antibiotic activity-are also promising candidates for cancer treatment. Yet the exact anticancer mechanism(s) of these compounds still remains unclear. In this study, we systematically investigated RM4819 and NTZ in 2D and 3D colorectal cancer culture systems. Both compounds strongly inhibited proliferation of colon carcinoma cell lines by promoting G1 phase cell cycle arrest. Thiazolide-induced cell cycle arrest was independent of the p53/p21 axis, but was mediated by inhibition of protein translation via the mTOR/c-Myc/p27 pathway, likely caused by inhibition of mitochondrial respiration. While both thiazolides demonstrated mitochondrial uncoupling activity, only RM4819 inhibited the mitochondrial respiratory chain complex III. Interestingly, thiazolides also potently inhibited the growth of murine colonic tumoroids in a comparable manner with cisplatin, while in contrast to cisplatin thiazolides did not affect the growth of primary intestinal organoids. Thus, thiazolides appear to have a tumor-selective antiproliferative activity, which offers new perspectives in the treatment of colorectal cancer.

Abstract
OBJECTIVE The canonical Wnt signaling pathway has been shown to be involved in regulating chondrocyte hypertrophic differentiation during Osteoarthritis (OA). The aim of this study was to test the therapeutic potential of two stapled peptide canonical Wnt inhibitors - SAH-Bcl9 and StAx-35R - in preventing Wnt induced cartilage changes in OA. METHODS Primary neonatal murine chondrocytes and cartilage explants from OA patients undergoing total joint replacement for knee OA, were used for microscopy to determine matrix and cell penetrating capacity of fluorescein isothiocyanate FITC-tagged SAH-Bcl9 and StAx-35R peptides. T cell factor/lymphoid enhancer-binding factor (TCF/LEF) reporter assays were used to monitor the inhibition of Wnt3a induced β-catenin signaling by each peptide. Changes in chondrocyte phenotypic marker gene expression were analyzed by qRT PCR. RESULTS Both peptides localized intercellular in primary murine chondrocytes and cartilage explants. They inhibited Wnt3a induced TCF/LEF promoter activity in primary murine chondrocytes. Both inhibitors did not rescue Wnt3a altered expression of chondrocyte phenotypic genes (Sox9, Col2a1, Acan) and hypertrophy marker gene (Col10a1) at high doses (100 ng/ml). Upon application of 10 ng/ml Wnt3a, StAx-35R partially reversed the Wnt effect on Sox9 and Col2a1 gene expression. Both peptides, however, reversed the downregulation of SOX9 and aggrecan (ACAN), and decrease of COL10A1 gene expression in preserved human OA cartilage explants. CONCLUSION These data indicate that blockade of canonical Wnt signaling might be a therapeutic strategy to treat early OA cases and protect further cartilage degradation by preventing chondrocyte hypertrophic differentiation.

Abstract
Abstract
Background: Dose-dense therapies have had a major impact on reducing toxicity and improving outcomes in breast cancer. A combination of docetaxel plus cyclophosphamide (TC) every 3 weeks has emerged as a common chemotherapy regimen used for treatment of node-negative or lower-risk node-positive breast cancer. We tested whether it is feasible to deliver TC on a dose-dense schedule.
Patients and Methods: We enrolled women with early stage breast cancer on a single-arm phase II study of adjuvant dose-dense TC (ddTC) through a regional oncology network (WON). All women completed primary surgery; subsequent therapy with TC was deemed appropriate by the treating physician. Planned treatment was docetaxel 75 mg/m2 plus cyclophosphamide 600 mg/m2 every 2 weeks for 4 cycles with subcutaneous pegfilgrastim 6 mg administered 24-48 hours after the administration of each chemotherapy cycle. The primary endpoint was feasibility of administering therapy within 10 weeks. A Simon Optimal 2-Stage design was employed for the study design.
Results: Of 42 women enrolled, 41 were evaluable by prespecified criteria. Median age was 54 (28-73). Most subjects had node negative (73%) or hormone receptor positive (71%) tumors. Of the 41 subjects, 37 (90.2%) completed therapy within 10 weeks and 34 (83%) completed therapy at 8 weeks without dose modification. Rates of grade 2 neuropathy were similar to that reported previously (15%) and there were no cases of grade 3 or higher neuropathy. The rate of neutropenic fever was low (2.5%). Rash and plantar/palmar erythrodythesia were common and reached grade 3 in four subjects (9.8%).
Conclusion: Dose-dense TC is feasible with tolerability profiles similar to standard TC and a low likelihood of neutropenic fever. This study supports further clinical development of this 8-week adjuvant chemotherapy regimen.

Abstract
6585 Background: We compared two existing sets of QIs for colorectal cancer care to evaluate our performance as compared to published data. We also explored reasons for non-adherence to these QIs to determine how we could increase our compliance. Methods: Chart review of all patients who were newly diagnosed with colorectal cancer at our institution in 2004 and 2005 for compliance with QIs for colorectal cancer care as presented by National Initiative for Cancer Care Quality (NICCQ) and Moffitt Network Initiative on Practice Quality (MNIPQ). When 85% compliance was not observed, charts were reviewed as to why care differed from QI. Results: Adherence rate was less than 85% in 5 of 25 NICCQ colon cancer measures and patients overall received 83% of recommended care. Reasons for <85% adherence on NICCQ were most often due to patient decision (patient decision after informed discussion, refusal of treatment, patient initiated delay) or co-morbidity (poor wound healing, infection, medical co-morbidity). In one item regarding counseling of family members about colorectal screening we were truly noncompliant without documentation of reason. Review of MNIPQ items observed less than 85% adherence rate in 2 of 9. Reason for non-adherence in MNIPQ review was due most often to co- morbidity, and true noncompliance (no reason documented for lack of pretreatment CEA). Conclusions: Our adherence rates for NICCQ and MNIPQ measures compare favorably with published values. Lower compliance rates on NICCQ and MNIPQ measures were most often due to patient choice or co-morbidities. In setting benchmarks for these individual QIs it should be noted that for some indicators (such as those regarding adjuvant therapy) higher percent adherence does not always reflect better care. Higher compliance may actually mean that thoughtful consideration of patient co-morbidity and complications, or including patients in decision making is not occurring or that the population being served is younger or has fewer co-morbidities. Other indicators such as those regarding staging documentation, documentation of chemotherapy, and patient education factors the higher the compliance the better. We conclude that some sampling of reason for non- adherence is necessary when assessing quality of care. No significant financial relationships to disclose.

Abstract
We report on results of a measurement of meson production in central Pb-Au collisions at E(lab) = 158A GeV. For the first time in the history of high energy heavy-ion collisions, phi mesons were reconstructed both in the K+K- and the dilepton decay channels in the same experiment. This measurement yields rapidity densities near midrapidity, from the two decay channels, of 2.05 +/- 0.14(stat) +/- 0.25(syst) and 2.04 +/- 0.49(stat) +/- 0.32(syst), respectively. The shape of the measured transverse momentum spectrum is also in close agreement in both decay channels. The data rule out a possible enhancement of the phi yield in the leptonic over the hadronic decay channel of a factor 1.6 or larger at the 95% C.L. This rules out the discrepancy reported in the literature between measurements of the hadronic and dimuon decay channels by two different experiments.

Abstract
We report on first measurements of low-mass electron-positron pairs in Pb-Au collisions at the CERN SPS beam energy of 40 AGeV. The observed pair yield integrated over the range of invariant masses 0.2<m</=1 GeV/c(2) is enhanced over the expectation from neutral meson decays by a factor of 5.9+/-1.5(stat)+/-1.2(syst data)+/-1.8(syst meson decays), somewhat larger than previously observed at the higher energy of 158 AGeV. The results are discussed with reference to model calculations based on pi(+)pi(-)-->e(+)e(-) annihilation with a modified rho propagator. They may be linked to chiral symmetry restoration and support the notion that the in-medium modifications of the rho are more driven by baryon density than by temperature.

Abstract
Based on an evaluation of data on pion interferometry and on particle yields at midrapidity, we propose a universal condition for thermal freeze-out of pions in heavy-ion collisions. We show that freeze-out occurs when the mean free path of pions lambda(f) reaches a value of about 1 fm, which is much smaller than the spatial extent of the system at freeze-out. This critical mean free path is independent of the centrality of the collision and beam energy from the Alternating Gradient Synchrotron to the Relativistic Heavy Ion Collider.

Abstract
While several cellular proteins are incorporated in the human immunodeficiency virus type 1 virion, cyclophilin (CyP) A is the only one whose absence has been demonstrated to impair infectivity. Incorporation of the cytosolic protein results from interaction with a highly exposed Pro-rich loop in the N-terminal region of the capsid (CA) domain of the precursor polyprotein, Pr55(Gag). Even when prevented from interacting with CyP A, Pr55Gag still forms particles that proceed to mature into morphologically wild-type virions, suggesting that CyP A influences a postassembly event. The nature of this CyP A influence has yet to be elucidated. Here, we show that while CyP A binds both Gag and mature CA proteins, the two binding interactions are actually different. Tryptophan 121 (W121) in CyP A distinguished the two proteins: a phenylalanine substitution (W121F) impaired binding of mature CA protein but not of Gag. This indicates the occurrence of a maturation-dependent switch in the conformation of the Pro-rich loop. A structural consequence of Gag binding to CyP A was to block this maturational refolding, resulting in a 24-kDa CA protein retaining the immature Pro-rich loop conformation. Using trypsin as a structure probe, we demonstrate that the conformation of the C-terminal region in mature CA is also a product of maturational refolding. Binding to wild-type CyP A altered this conformation, as indicated by a reduction in the accessibility of Cys residue(s) in the region to chemical modification. Hence, the end result of binding to CyP A, whether the Pro-rich loop is in the context of Gag or mature CA protein, is a structurally modified mature CA protein. The postassembly role of CyP A may be mediated through these modified mature CA proteins.

Abstract
61 Patients with caput obstipum musculare were operated on our clinic between 1968 to 1985. 45 patients were examined after cosmetic and functional criteria (Manitz 1974, Stein et al., 1985). We found 28 "very good", 10 "good", 6 "satisfactory" and 1 "insufficient" results after the criteria established by Leuschner (1967).
