Abstract
498 Background: Prior study, demonstrating differential immunohistochemical EGFR expression between the primary colon cancer and the liver metastasis, suggested possible molecular differences between the two tumor sites. This questions the relevance of obtaining genomic information from the primary tumor to guide adjuvant treatment. In this study we examine whether there are genomic differences specific to metastatic nodes versus the paired colon primary samples. Methods: Using 30 primary and lymph node metastasis pairs (dissected for >80% tumor from paraffin embedded tissue), we obtained a dataset of copy number derived from the Affymetrix Oncoscan Molecular Inversion Probe platform. Using the Nexus Copy Number software for processing, we used the default automatic segmentation of the copy number data with a threshold for calling copy number gains/losses of 2.3/1.7. Subsequently we applied the Wilcoxon signed-rank test in order to find regions showing copy number imbalance that differ between the paired nodes and tumors correcting for multiple comparisons by performing permutation-based estimation of the false discovery rate permuting the samples 100 times. Results: Using 40 ng of total DNA from paraffin embedded tumor from primary and tumor in positive nodes, we obtained high quality, genome wide copy number data. Using FDR < 0.1, we identified four chromosomal segments that showed statistically significant increased likelihood of copy number gains in the primary tumor compared to the tumor-containing node. Thirty five percent of tumor-bearing lymph nodes were copy number normal at the EGFR locus whereas the corresponding primary tumor showed amplification at 7p11.2 (includes the EGFR gene). A similar pattern was observed for 8q24, 14q11.2, and 20q12-q13; regions associated with aggressive tumor behavior. Conclusions: Our results demonstrate four significant differences between the primary tumor and lymph node metastasis and in all cases the metastasis were copy number normal compared to the copy number gain observed in the primary tumor. These results support the importance to examine differences at the genome level between the metastatic tumor site and the primary.

Abstract
Leading hypotheses to explain helminth-mediated protection against autoimmunity postulate that type 2 or regulatory immune responses induced by helminth infections in the host limit pathogenic Th1-driven autoimmune responses. We tested these hypotheses by investigating whether infection with the filarial nematode Litomosoides sigmodontis prevents diabetes onset in IL-4-deficient NOD mice and whether depletion or absence of regulatory T cells, IL-10, or TGF-β alters helminth-mediated protection. In contrast to IL-4-competent NOD mice, IL-4-deficient NOD mice failed to develop a type 2 shift in either cytokine or Ab production during L. sigmodontis infection. Despite the absence of a type 2 immune shift, infection of IL-4-deficient NOD mice with L. sigmodontis prevented diabetes onset in all mice studied. Infections in immunocompetent and IL-4-deficient NOD mice were accompanied by increases in CD4(+)CD25(+)Foxp3(+) regulatory T cell frequencies and numbers, respectively, and helminth infection increased the proliferation of CD4(+)Foxp3(+) cells. However, depletion of CD25(+) cells in NOD mice or Foxp3(+) T cells from splenocytes transferred into NOD.scid mice did not decrease helminth-mediated protection against diabetes onset. Continuous depletion of the anti-inflammatory cytokine TGF-β, but not blockade of IL-10 signaling, prevented the beneficial effect of helminth infection on diabetes. Changes in Th17 responses did not seem to play an important role in helminth-mediated protection against autoimmunity, because helminth infection was not associated with a decreased Th17 immune response. This study demonstrates that L. sigmodontis-mediated protection against diabetes in NOD mice is not dependent on the induction of a type 2 immune shift but does require TGF-β.

Abstract
BACKGROUND The variability in the number of lymph nodes examined needs to be taken into account for adequate staging. The definition of nodal staging was refined by quantifying the likelihood of N2 disease when the patient had fewer than four positive LN. METHODS In a retrospective study a total of 548 patients with node positive rectal cancer and curative surgery between 1990 and 2006 were identified. The misclassification of pN staging was estimated with a Bayesian computation. The prognostic value of the calculated probability, lymph node ratio (LNR), and nodal stage was assessed with Cox proportional hazard regression. RESULTS A probability of understaging of 40% or more indicated worse prognosis of cancer-specific survival (CSS) with hazard ratio 2.6 (95%CI: 1.8-3.9, P < 0.001). The concordance index of a multivariate model with probability of N2 disease as a prognostic factor for survival was 0.68 for all patients and 0.75 for patients with less than 10 lymph nodes examined. CONCLUSION Utilizing estimated probabilities of N2 disease improves our ability to predict survival, in particular in patients with low LN count. These probabilities allow for a simple rule in patient counseling and clinical decision making.

Abstract
OBJECTIVE The purpose of this study was to compare obstetric outcomes and maternal satisfaction in nulliparous women in spontaneous labor who used patient-controlled epidural analgesia (PCEA) vs continuous epidural infusion (CEI). STUDY DESIGN We conducted a double-masked trial of 270 nulliparous women who were assigned randomly to 3 groups (with a concentration 0.1% bupivacaine and 2 μg/mL fentanyl): group I, CEI-only (10 mL/h); group II, CEI + PCEA (CEI 10 mL/h plus PCEA 10 mL, at 20 minutes); group III, PCEA-only (10 mL, at 20 minutes). A PCEA bolus button was given to each subject. The primary outcome was the dosage of local anesthetic that was used. RESULTS The total milligrams of bupivacaine that were used was less in the PCEA-only group compared with CEI: group I. 74.8 ± 36 mg; group II, 97.3 ± 53 mg; group III, 52.4 ± 42 mg (P < .001). Pain with pushing, however, was worse in the PCEA-only group. Median satisfaction scores were similar (scale, 0 [best] to 100 [worst]: group I, 0; group II, 0; group III, 0 (P = .23). CONCLUSION PCEA results in less anesthetic used, and maternal satisfaction remains high without a continuous infusion. Pain with pushing, however, was worse with the PCEA alone.

Abstract
Mounting evidence suggests that helminth infections protect against autoimmune diseases. As helminths cause chronic IgE-mediated activation of basophils and mast cells we hypothesized that continuous activation of these cells could prevent diabetes onset in nonobese diabetic (NOD) mice in the absence of infection. Anti-FcεR1 activated basophils and mast cells and resulted in the release of IL-4 and histamine into the bloodstream. Anti-FcεR1-treated NOD mice showed a type 2 shift in insulin-specific antibody production and exhibited significant delays in diabetes onset. IL-4 responses played a partial role as the protective effect of anti-FcεR1 therapy was diminished in IL-4-deficient NOD mice. In contrast, histamine signaling was not required as anti-FcεR1-mediated protection was not reduced in mice treated with histamine receptor blockers. These results demonstrate that anti-FcεR1 therapy delays diabetes onset in NOD mice and suggest that chronic basophil and mast cell activation may represent a new avenue of therapy for Th1-associated autoimmune diseases.

Abstract
We studied 174 consecutive patients with relapsed refractory multiple myeloma (MM) enrolled on a phase II clinical trial of pomalidomide plus low-dose dexamethasone at Mayo Clinic. Extramedullary disease (EMD) was present at the time of trial entry in 7.5% (13 of 174 patients). The rate of EMD in the first 3 years following diagnosis of MM was 3%. The response of EMD to pomalidomide plus low-dose dexamethasone included two complete and two partial responses among the 13 patients (response rate, 31%). Overall survival measured from trial entry was significantly shorter for patients with treatment-emergent EMD compared with those who did not have EMD, (median 16 months versus not reached, P=0.002).

Abstract
The first soft x-ray radiation flux measurements from hohlraums using both a 96 and a 192 beam configuration at the National Ignition Facility have shown high x-ray conversion efficiencies of ∼85%-90%. These experiments employed gold vacuum hohlraums, 6.4 mm long and 3.55 mm in diameter, heated with laser energies between 150-635 kJ. The hohlraums reached radiation temperatures of up to 340 eV. These hohlraums for the first time reached coronal plasma conditions sufficient for two-electron processes and coronal heat conduction to be important for determining the radiation drive.

Abstract
Chronic helminth infections induce a type 2 immune response characterized by eosinophilia, high levels of IgE, and increased T cell production of type 2 cytokines. Because basophils have been shown to be substantial contributors of IL-4 in helminth infections, and because basophils are capable of inducing Th2 differentiation of CD4(+) T cells and IgE isotype switching in B cells, we hypothesized that basophils function to amplify type 2 immune responses in chronic helminth infection. To test this, we evaluated basophil function using the Litomosoides sigmodontis filaria model of chronic helminth infection in BALB/c mice. Time-course studies showed that eosinophilia, parasite Ag-specific CD4(+) T cell production of IL-4 and IL-5 and basophil activation and IL-4 production in response to parasite Ag all peak late (6-8 wk) in the course of L. sigmodontis infection, after parasite-specific IgE has become detectable. Mixed-gender and single-sex worm implantation experiments demonstrated that the relatively late peak of these responses was not dependent on the appearance of circulating microfilariae, but may be due to initial low levels of parasite Ag load and/or habitation of the developing worms in the pleural space. Depletion of basophils throughout the course of L. sigmodontis infection caused significant decreases in total and parasite-specific IgE, eosinophilia, and parasite Ag-driven CD4(+) T cell proliferation and IL-4 production, but did not alter total worm numbers. These results demonstrate that basophils amplify type 2 immune responses, but do not serve a protective role, in chronic infection of mice with the filarial nematode L. sigmodontis.

Abstract
The first 96 and 192 beam vacuum Hohlraum target experiments have been fielded at the National Ignition Facility demonstrating radiation temperatures up to 340 eV and fluxes of 20 TW/sr as viewed by DANTE representing an ∼20 times flux increase over NOVA/Omega scale Hohlraums. The vacuum Hohlraums were irradiated with 2 ns square laser pulses with energies between 150 and 635 kJ. They produced nearly Planckian spectra with about 30±10% more flux than predicted by the preshot radiation hydrodynamic simulations. To validate these results, careful verification of all component calibrations, cable deconvolution, and software analysis routines has been conducted. In addition, a half Hohlraum experiment was conducted using a single 2 ns long axial quad with an irradiance of ∼2×10(15) W/cm(2) for comparison with NIF Early Light experiments completed in 2004. We have also completed a conversion efficiency test using a 128-beam nearly uniformly illuminated gold sphere with intensities kept low (at 1×10(14) W/cm(2) over 5 ns) to avoid sensitivity to modeling uncertainties for nonlocal heat conduction and nonlinear absorption mechanisms, to compare with similar intensity, 3 ns OMEGA sphere results. The 2004 and 2009 NIF half-Hohlraums agreed to 10% in flux, but more importantly, the 2006 OMEGA Au Sphere, the 2009 NIF Au sphere, and the calculated Au conversion efficiency agree to ±5% in flux, which is estimated to be the absolute calibration accuracy of the DANTEs. Hence we conclude that the 30±10% higher than expected radiation fluxes from the 96 and 192 beam vacuum Hohlraums are attributable to differences in physics of the larger Hohlraums.

Abstract
Using partially deleted genes, we have identified an upstream control signal required for transcription of a Bombyx mori (silkworm) tRNA(2) (Ala) gene. The 5' boundary of this essential region lies between 34 and 11 nucleotides preceding the transcription initiation site. Sequences in the 5' half of the tRNA(2) (Ala) coding region are also important. Both regions contain oligonucleotides that are conserved among several Bombyx genes transcribed by RNA polymerase III, suggesting that these sequences may have a general control function.
