Abstract
Abstract
Introduction
Accumulating evidence suggests that chronotype, i.e., circadian topology of an individual indicating morning or evening type, is associated with inflammation. To date, no study has examined the relationship between chronotype and inflammation in colorectal cancer patients. We investigated the associations between chronotype and inflammatory and angiogenesis biomarkers in colorectal cancer patients.
Methods
We used pre-surgery serum samples from n=67 newly diagnosed colorectal cancer patients (stage I-IV) recruited at the ColoCare Study site in Heidelberg, Germany. The ColoCare Study is an ongoing, international, multisite, prospective cohort study in colorectal cancer patients. Inflammatory and angiogenesis biomarkers [c-reactive protein (CRP), interleukin (IL)-6, IL-8, monocyte chemoattractant protein-1 (MCP-1), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1)] were measured at the Huntsman Cancer Institute, USA using the Meso Scale Discovery platform and were log transformed. Chronotype was assessed prior to surgery with the reduced Morningness-Eveningness Questionnaire (rMEQ; scale 4–25; a higher score indicates more morning-type). Patients were dichotomized, based on the median values for rMEQ, into 2 groups: rMEQ-low (score≤16.0; n=35; indicating more evening-type) or rMEQ-high (score>16.0; n=32; indicating more morning-type).
Results
Using Mann-Whitney U test, we observed that rMEQ-low group (i.e., more evening-type) compared to rMEQ-high group (i.e., more morning-type) had approx. two times significantly higher levels of log transformed IL-6 (mean=2.24 vs. 1.30; U=382.0; Z=-2.23; p=0.03), but not for other inflammatory or angiogenesis biomarkers. This association between chronotype and IL-6 was maintained even after adjusting for age, sex, tumor stage, tumor site, and sleep duration using a generalized estimating equations model (adjusted mean difference=1.10; 95% confidence interval=0.33, 1.88; p=0.01; effect size, Cohen’s d=0.69).
Conclusion
These preliminary findings suggest that the evening chronotype is associated with increased IL-6 inflammatory biomarker in colorectal cancer patients. Further research is needed to confirm and understand the mechanistic underpinnings of the observed results.

Abstract
Abstract
Over the past decade, genomic characterization of tumors has shed enormous light on the molecular underpinnings of cancer. These discoveries have led to the development of novel therapies and preventive measures that have already revolutionized cancer care. Despite this progress, the genomics of metastatic breast cancer (MBC), one of the leading causes of cancer death in the U.S., remains poorly understood.
The challenge in studying tumor samples from patients with MBC has been that the tumors from most patients are not available for research, largely because the vast majority of patients are cared for in community settings where genomics studies are not typically conducted. To address this, we have launched a nationwide study, The Metastatic Breast Cancer Project, which seeks to empower patients to accelerate cancer research through sharing their samples and clinical information. We have developed an outreach program in collaboration with MBC advocacy organizations to connect MBC patients around the country with genomics research performed at the Broad Institute, allowing them to participate regardless of where they live.
Working with MBC patients and advocates, we designed a website (www.mbcproject.org) with an online questionnaire that allows patients with MBC to provide information about themselves and their cancer. Based on their answers, patients are offered an electronic consent form that explains the risks and benefits of the study and asks for permission to obtain a portion of their stored tumor tissue, a saliva sample, and copies of their medical records. For patients who consent, our clinical research team contacts their physicians and obtains copies of their medical records, which are reviewed to confirm eligibility. Enrolled patients are sent a saliva kit and asked to mail back a saliva sample, which is used to extract germline DNA. The clinical research team also contacts the patient's pathology department and requests a portion of the tumor to be sent to the Broad Institute for genomic analysis. Whole exome and transcriptome sequencing is performed on tumor and germline DNA. Sequencing data are linked to de-identified clinical information, and the resulting data are used to identify drivers of tumorigenesis, mechanisms of response and resistance to therapies, and diagnostic, prognostic, and therapeutic biomarkers. The database of clinically annotated genomic information will be shared with the NIH and the cancer research community. Study updates and discoveries are shared at regular intervals with all patients who complete the initial questionnaire.
This direct-to-patient approach should be particularly enabling for the identification of patients with rare phenotypes or clinical behavior. For this reason, the first cohorts being studied are patients with extraordinary responses to therapies and patients who present with de novo MBC. Additional cohorts will be added in the future, including young women with MBC and patients with drug-resistant MBC. This project seeks to establish a patient-researcher partnership to accelerate genomic discoveries and improve outcomes in MBC, and may ultimately serve as a means to build a new clinical and translational research model for all patients with cancer.

Abstract
PURPOSE The aim of this study was to assess different aspects of reliability in high-resolution ultrasonography (HRUS) of the peripheral nerves and to establish reference values for the most frequently examined nerve segments. MATERIALS AND METHODS A nerve size parameter, the cross-sectional area (CSA) of the C5, C6 and C7 cervical roots, the median, ulnar, radial, superficial radial, peroneal, tibial, and the sural nerves was measured using HRUS at a total of 14 predefined anatomical sites in two different cohorts of healthy subjects (n = 56), and the inter-rater, intra-rater and inter-equipment reliability of measurements was assessed. RESULTS The mean CSA of the 14 nerve segments ranged from 2 to 10 mm(2). The intra-rater, inter-rater and inter-equipment reliability was high with intraclass correlation coefficients of 0.93, 0.98, and 0.86, respectively. The CSA values showed no consistent correlation with age, height, and body weight, but males had significantly larger values than females for nerve segments on the arm after correcting for age, weight and height in multivariate analysis. CSA values did not differ when two independent cohorts were compared. CONCLUSION Peripheral nerve ultrasonography is a reliable and reproducible diagnostic method in the hands of experienced examiners. Normal values for several upper and lower extremity nerves are provided by our study.

Abstract
Targeting HER2 with antibodies or small molecule inhibitors in HER2-positive breast cancer leads to improved survival, but resistance is a common clinical problem. To uncover novel mechanisms of resistance to anti-HER2 therapy in breast cancer, we performed a kinase open reading frame screen to identify genes that rescue HER2-amplified breast cancer cells from HER2 inhibition or suppression. In addition to multiple members of the MAPK (mitogen-activated protein kinase) and PI3K (phosphoinositide 3-kinase) signaling pathways, we discovered that expression of the survival kinases PRKACA and PIM1 rescued cells from anti-HER2 therapy. Furthermore, we observed elevated PRKACA expression in trastuzumab-resistant breast cancer samples, indicating that this pathway is activated in breast cancers that are clinically resistant to trastuzumab-containing therapy. We found that neither PRKACA nor PIM1 restored MAPK or PI3K activation after lapatinib or trastuzumab treatment, but rather inactivated the pro-apoptotic protein BAD, the BCl-2-associated death promoter, thereby permitting survival signaling through BCL-XL. Pharmacological blockade of BCL-XL/BCL-2 partially abrogated the rescue effects conferred by PRKACA and PIM1, and sensitized cells to lapatinib treatment. These observations suggest that combined targeting of HER2 and the BCL-XL/BCL-2 anti-apoptotic pathway may increase responses to anti-HER2 therapy in breast cancer and decrease the emergence of resistant disease.

Abstract
Abstract
Amplification and/or overexpression of the receptor tyrosine kinase HER2 occurs in 20-25% of breast cancers, and is associated with poor prognosis. Targeting of HER2 with drugs such as trastuzumab, lapatinib, or pertuzumab has led to clinical benefit in patients with both metastatic and early-stage HER2-amplified breast cancer. However, resistance and disease progression always occurs in patients with metastatic disease, and many patients with early-stage breast cancer experience recurrences despite adjuvant anti-HER2 therapy. As such, understanding the mechanisms of resistance to anti-HER2 therapy has important clinical implications.
Recent studies have identified mutations in PIK3CA, the gene encoding the catalytic subunit of Phosphatidylinositol 3 kinase (PI3K), as one mechanism of resistance to trastuzumab. However, such mutations are present in only a fraction of trastuzumab-resistant breast cancers. We therefore sought to uncover novel mechanisms of resistance to anti-HER2 therapy through an unbiased screen for kinases and kinase-related molecules that are able to rescue HER2-amplified breast cancer cells from HER2 inhibition.
We utilized a library of nearly 600 lentivirally-delivered open reading frames (ORFs) to constitutively express the coding sequence of each molecule individually in HER2-amplified BT474 breast cancer cells in arrayed high-throughput format. We conducted two parallel screens for the ability of each of these molecules to rescue cells from anti-HER2 therapy: one in which we treated the cells with a lapatinib-like drug that inhibits the kinase activity of HER2 and EGFR, and one in which we lentivirally delivered a short hairpin RNA that suppresses expression of HER2.
We identified those ORFs that restored viability of BT474 cells to greater than two standard deviations above the median of all ORFs in each screen. Multiple members of the MAPK and PI3K signaling pathways scored in both screens, serving to validate the approach. In addition, the survival kinases PIM1 and PRKACA scored robustly. Mechanistic studies suggest that these kinases may confer resistance by restoring the phosphorylation of, and thereby inactivating, the pro-apoptotic protein BAD. Consistent with this finding, overexpression of Bcl-xl, which is inhibited by BAD, also conferred resistance to lapatinib in HER2-amplified breast cancer cells. Furthermore, pharmacological blockade of Bcl-xl and Bcl-2 with ABT-263 enhanced lapatinib-induced killing of HER2-amplified breast cancer cells in vitro, and partially abrogated the rescue conferred by both PRKACA and PIM1. These findings suggest that combined inhibition of HER2 and the anti-apoptotic molecules Bcl-xl and Bcl-2 could enhance tumor cell eradication and prevent or delay the emergence of resistant disease.

Abstract
Vici syndrome is a rare, genetically unresolved congenital multisystem disorder comprising agenesis of the corpus callosum, cataracts, immunodeficiency, cardiomyopathy, and hypopigmentation. An associated neuromuscular phenotype has not previously been described in detail. We report on an infant with clinical features suggestive of Vici syndrome and additional sensorineural hearing loss. Muscle biopsy revealed several changes including markedly increased variability in fiber size, increased internal nuclei, and abnormalities on Gomori trichrome and oxidative stains, raising a wide differential diagnosis including neurogenic atrophy, centronuclear myopathy (CNM) or a metabolic (mitochondrial) cytopathy. Respiratory chain enzyme studies, however, were normal and sequencing of common CNM-associated genes did not reveal any mutations. This case expands the clinical spectrum of Vici syndrome and indicates that muscle biopsy ought to be considered in infants presenting with suggestive clinical features. In addition, we suggest that Vici syndrome is considered in the differential diagnosis of infants presenting with congenital callosal agenesis and that additional investigation has to address the possibility of associated ocular, auditory, cardiac, and immunologic involvement when this radiologic finding is present.

Abstract
This Letter reports on a search for nu(mu) --> nu(e) transitions by the MINOS experiment based on a 3.14x10(20) protons-on-target exposure in the Fermilab NuMI beam. We observe 35 events in the Far Detector with a background of 27+/-5(stat)+/-2(syst) events predicted by the measurements in the Near Detector. If interpreted in terms of nu(mu) --> nu(e) oscillations, this 1.5sigma excess of events is consistent with sin2(2theta(13)) comparable to the CHOOZ limit when |Delta m2|=2.43x10(-3) eV2 and sin2(2theta(23))=1.0 are assumed.

Abstract
We report the first detailed comparisons of the rates and spectra of neutral-current neutrino interactions at two widely separated locations. A depletion in the rate at the far site would indicate mixing between nu(mu) and a sterile particle. No anomalous depletion in the reconstructed energy spectrum is observed. Assuming oscillations occur at a single mass-squared splitting, a fit to the neutral- and charged-current energy spectra limits the fraction of nu(mu) oscillating to a sterile neutrino to be below 0.68 at 90% confidence level. A less stringent limit due to a possible contribution to the measured neutral-current event rate at the far site from nu(e) appearance at the current experimental limit is also presented.

Abstract
A search for a sidereal modulation in the MINOS near detector neutrino data was performed. If present, this signature could be a consequence of Lorentz and CPT violation as predicted by the effective field theory called the standard-model extension. No evidence for a sidereal signal in the data set was found, implying that there is no significant change in neutrino propagation that depends on the direction of the neutrino beam in a sun-centered inertial frame. Upper limits on the magnitudes of the Lorentz and CPT violating terms in the standard-model extension lie between 10(-4) and 10(-2) of the maximum expected, assuming a suppression of these signatures by a factor of 10(-17).

Abstract
This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical oscillations of neutrino flavor with mass splitting |Deltam2| = (2.43+/-0.13) x 10(-3) eV2 (68% C.L.) and mixing angle sin2(2theta) > 0.90 (90% C.L.). Our data disfavor two alternative explanations for the disappearance of neutrinos in flight: namely, neutrino decays into lighter particles and quantum decoherence of neutrinos, at the 3.7 and 5.7 standard-deviation levels, respectively.

Abstract
BACKGROUND Although a large number of pathology-specific websites (PSWs) are accessible on the internet, the potential use of PSWs is relatively unknown among pathologists. As a PSW-directory does not exist, it may be difficult to find certain resources that are scattered over the internet. AIMS To critically revisit PSWs in order to create a collection of selected websites that may be useful for practising pathologists worldwide. METHODS Using special medical databases and link collections, extensive search for PSWs was performed on the world wide web. Each website was evaluated with regard to content and practical use for pathologists. RESULTS PSWs contain electronic training manuals, journals, case collections, photo-archives, link directories, or slide collections of virtual microscopy. PSWs offer lavishly illustrated education material for undergraduates and postgraduates in pathology, but may also be very useful as reference books or as an instrument of continuing medical education for experienced pathologists. The paper shows how to find PSWs, and presents an annotated list of 100 of the best PSWs. CONCLUSIONS PSWs as a whole form a heterogeneous patchwork of information. It is suggested that a central catalogue listing all PSWs that are available worldwide be established. This database would enable pathologists to have immediate access to all up-to-date pathology-specific resources on the internet, without the need to perform any laborious web research for themselves. It is hoped that in the future, the repertoire of on-line resources in pathology will be systematically perfected. The internet will then play a central role in the daily practice of pathologists as a medium of information and communication.

Abstract
This Letter reports results from the MINOS experiment based on its initial exposure to neutrinos from the Fermilab NuMI beam. The rates and energy spectra of charged current nu(mu) interactions are compared in two detectors located along the beam axis at distances of 1 and 735 km. With 1.27 x 10(20) 120 GeV protons incident on the NuMI target, 215 events with energies below 30 GeV are observed at the Far Detector, compared to an expectation of 336+/-14 events. The data are consistent with nu(mu) disappearance via oscillations with |Delta(m)2/32|=2.74 +0.44/-0.26 x10(-3)eV(2) and sin(2)(2theta(23))>0.87 (68% C.L.).

Abstract
The shortage of donor organs is reflected in the growing number of patients on the waiting list for kidney transplantation worldwide. It seems to be sensible to expand the scarce donor pool by the cautious use of extended donor criteria. Kidneys from a 21-year-old deceased donor road traffic accident victim who suffered acute renal failure (ARF) due to myolysis were transplanted. Both transplantations were successful after an initial period of delayed graft function. Therefore, kidneys from deceased donors with ARF should not be excluded for transplantation in general.

Abstract
Renal failure is rarely the presenting manifestation of non-Hodgkin's lymphoma. We describe the unusual case of a patient who presented with uremia due to lymphomatous infiltration of the kidney by a low-grade T-cell lymphoma. The diagnosis of lymphoma was made by renal biopsy. Extrarenal nodular or extra-nodular involvement could not be detected. However, simultaneously, a lymphoplasmacytic lymphoma was found on bone marrow biopsy associated with IgM paraproteinemia. To our knowledge, this is the first report of a renal T-cell lymphoma associated with Waldenström's macroglobulinemia.

Abstract
A widely studied example of vertebrate plasticity is LTP (long-term potentiation), the persistent synaptic enhancement that follows a brief period of coinciding pre- and post-synaptic activity. During LTP, different kinases, including CaMKII (calcium/calmodulin-dependent protein kinase II) and protein kinase A, become activated and play critical roles in induction and maintenance of enhanced transmission. Biochemical analyses have revealed several regulated phosphorylation sites in the AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor subunits, GluR1 and GluR4. The regulated insertion of these receptors is a key event in the induction of LTP. Here, we discuss the phosphorylation of GluR1 and GluR4 and its role in receptor delivery and neuronal plasticity.

Abstract
Interferon-alpha has been used as standard therapy for patients with Philadelphia-positive chronic myeloid leukemia (CML) for more than 20 years. Recently randomized trials have shown a superiority of the tyrosine kinase inhibitor imatinib in respect to its efficacy to induce complete hematological and cytogenetic remissions and more importantly in overall survival. Although follow-up is much shorter for imatinib than for interferon-alpha, this data changed the treatment algorithms in this disease. At the end of the era of interferon-alpha as a single-drug first-line treatment for most patients we present a case report which exemplifies a rare but exciting property of interferon-alpha in CML: the induction of complete hematological and cytogenetic remissions which can persist over years after discontinuation of the drug. Hence, the enrollment of CML patients in clinical trials which explore a combination treatment of imatinib and interferon-alpha is warranted.

Abstract
In microsystem technology, four important material classes are established either for the generation or the replication of microstructured surfaces: silicon, polymers, metals and ceramics. Composite materials consisting of a polymer matrix and ceramic fillers show improved thermomechanical properties in comparison to polymers and can be introduced as a new additional material class. The substitution of micro-sized ceramic fillers by nano-sized ceramics in composites has a strong influence on the composite's physical properties: the reduction of ceramic particle size down to the nanometre scale results in an improved sinter activity owing to the large surface area. The fabrication of dense ceramics is simplified and can be used for a rapid prototyping of microstructured ceramic parts. The addition of nano-sized ceramics with particle sizes of <40 nm to polymers allows the manufacturing of transparent polymer based composites with modified refractive indices for use in polymer waveguides. The influence of the ceramic particle size, the ceramic content and different dispersion methods on the composite's physical properties are discussed.

Abstract
Constitutive activation of the wnt-signaling pathway plays an important role during both human and rat colon carcinogenesis and can be brought through mutations in either the adenomatous polyposis coli or the beta-catenin gene. Mutations found in the beta-catenin gene typically affect one out of four regulatory phosphorylation sites near the N-terminus of the beta-catenin protein. Whereas in human colon cancers, however, the majority of beta-catenin mutations directly alter threonine 41 or serine 45; the beta-catenin mutations found in chemically induced rat colon tumors seemed to cluster around codon 33 instead. Unlike previous studies, that have used relatively short-term (2-5 weeks) treatment with one of the alkylating agents 1,2,-dimethylhydrazine (DMH) or azoxymethane, we have investigated the mutational spectrum of the beta-catenin gene in a panel of rat colon tumors induced by long-term (20 weeks) DMH-treatment. We detected beta-catenin mutations in 12 of 33 (36%) tumors. Interestingly, only one of the beta-catenin mutations found affected the previously implicated codon 33 cluster region (Asp32Asn), whereas 11 of 12 (>90%) mutations represented identical C-->T transitions within codon 41 resulting in the common replacement of threonine by isoleucine. We propose a model in which codon 41 mutations bear higher oncogenic potential but are induced by DMH less frequently than mutations in the codon 33 cluster region. Consequently, only after sustained carcinogenic treatment, as is achieved in the long-term DMH-protocol, codon 41 mutations will be induced frequently enough to be present in all developing malignant lesions and, then, because of their higher oncogenic potential, these are selected for.

Abstract
Presumptive copper deficiency was diagnosed in hand-reared captive pronghorn (Antilocapra americana) at the Los Angeles Zoo. Clinical signs, which were manifested in growing fawns, included anemia, anorexia, diarrhea, progressive paresis/recumbency, and aortic rupture. The range of serum copper concentrations in fawns born during the 1989 season (0.08-0.67 ppm) was below levels considered normal for domestic sheep and goats (0.7-2.0 ppm) and below concentrations measured in adult pronghorn (0.4-1.43 ppm). Copper sulfate supplementation of the hand-rearing formula, which was initiated in 1989, resulted in a significant increase in mean (+/- SD) serum copper levels from 0.45 +/- 0.18 ppm before supplementation to 0.68 +/- 0.05 ppm after supplementation (P < 0.05). Fawns born in subsequent seasons (April 1990-August 1993) continued to be supplemented with copper in the hand-rearing formula. Mean serum copper concentration from these fawns (0.68 +/- 0.22 ppm) was similar to the mean values from supplemented 1989 fawns and adult pronghorn in this herd (0.85 +/- 0.34 ppm; P > 0.05). No clinical signs of copper deficiency were detected in any fawns after supplementation was started. Analyses of the herd's diet revealed marginal dietary copper levels. Suspected dietary deficiency was confirmed by marginal tissue and serum copper concentrations in some of the herd's adult animals. Dietary copper levels were corrected to prevent future cases of clinical copper deficiency.

Abstract
Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at square root(S)NN = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

Abstract
A prospective study was performed in patients with non-small cell lung cancer (NSCLC) to evaluate the prognostic importance of multiple molecular marker (p53, c-Ki-ras, c-erbB-2) testing. 103 patients with potentially curative resections (RO resection) for NSCLC in histopathological stages I-IIIA were included. SSCP analysis and DNA sequencing for p53 and c-Ki-ras genes were performed on paired tumour and normal lung tissue samples and immunohistochemistry (c-erbB-2) was done on frozen tissue sections with a specific anti-c-erbB-2 monoclonal antibody. 46/103 (44.6%) NSCLC showed p53 mutations and 17/103 (16.5%) c-Ki-ras mutations including 12/37 (32.4%) adenocarcinomas. Overexpression of c-erbB-2 (p185) was detected in 56/103 (54.4%) tumours. 24/103 (23.3%) NSCLC were negative for alterations in all 3 parameters (c-Ki-ras, p53 and p185) whereas 79/103 (76.7%) were positive for at least one of the 3 parameters. In a regression model including a multiple molecular marker parameter (negative for all 3 markers versus positive for at least one marker), histopathological stage (P<0.00001), respectively the pT (P<0.01) and pN (P<0.00001) categories and the multiple molecular marker parameter (P<0.01) were of significant prognostic importance. This study demonstrates that testing 3 molecular markers (c-Ki-ras, p53 and c-erbB-2) improves estimation of prognosis compared to single marker testing and appears to define low (82.6%+/-7.9% 5-year survival) and high risk (40.2%+/-5.5% 5-year survival) groups for treatment failure in potentially curative (RO) resected NSCLC.

Abstract
Sec12p is a type II membrane glycoprotein in the endoplasmic reticulum (ER) of Saccharomyces cerevisiae which is essential for transport vesicle budding. It is the guanine nucleotide exchange factor for the small GTP-binding protein Sar1p which is a constituent of COP II ER to Golgi vesicles. We report the sequence and localization of the human homologue to yeast Rer1p, which has recently been identified genetically as an essential component for retention of Sec12p in the ER. Reverse polymerase chain reaction was used to obtain cDNAs from HeLa cells. They code for a protein of 196 amino acids, corresponding to a molecular mass of 23 kDa. The translated sequence is 44% identical and 65% similar to yeast Rer1 protein. The four putative transmembrane domains are predicted to form a W-topology with both N- and C-terminus facing the cytosol. The functional activity of myc-tagged human Rer1 was demonstrated by the complementation of the RER1 deletion in S. cerevisiae. Mislocalization of the Sec12-reporter protein was reduced similar to the results obtained with yeast Rer1p. Human Rer1 protein was expressed in HeLa cells and the subcellular distribution analyzed by double immunofluorescence and immunoelectron microscopy of thawed cryosections. The tagged protein was localized to the Golgi apparatus and peripheral elements of the ER-Golgi interface. High overexpression leads to relocation of human Rer1 to ER-like structures together with KDEL-receptor and affects the structural organization of the Golgi apparatus. Under conditions of brefeldin A treatment, human Rer1 distributes together with recycling Golgi proteins.
