description: In the paper, we establish a blow-up criterion in terms of the integrability of the density for strong solutions to the Cauchy problem of compressible isentropic Navier-Stokes equations in \mathbb{R}^3 with vacuum, under the assumptions on the coefficients of viscosity: \frac{29μ}{3}>λ. This extends the corresponding results in [20, 36] where a blow-up criterion in terms of the upper bound of the density was obtained under the condition 7μ>λ. As a byproduct, the restriction 7μ>λin [12, 37] is relaxed to \frac{29μ}{3}>λfor the full compressible Navier-Stokes equations by giving a new proof of Lemma 3.1. Besides, we get a blow-up criterion in terms of the upper bound of the density and the temperature for strong solutions to the Cauchy problem of the full compressible Navier-Stokes equations in \mathbb{R}^3. The appearance of vacuum could be allowed. This extends the corresponding results in [37] where a blow-up criterion in terms of the upper bound of (ρ,\frac{1}ρ, θ) was obtained without vacuum. The effective viscous flux plays a very important role in the proofs.

description: Context Tumor-stroma-endocrine interactions favour pancreatic adenocarcinoma (PDAC) growth/ progression and PDAC-associated diabetes mellitus (DM). S100A8/A9 and the matrix methallo­proteinases (MMPs) 8 and 9 are overexpressed in PDAC stroma. Objective To verify whether S100A8, S100A9, MMP8 and MMP9 mRNA in peripheral blood mononuclear cells (PBMC) is useful for diagnosing and staging PDAC and/or for detecting PDAC-associated DM. To study the impact of S100A8/A9 and of PDAC-associated growth factors and cytokines on MMPs expression. Methods S100A8, S100A9, MMP8 e MMP9 mRNA were quantified by qRT-PCR in 62 PDAC, 37 chronic pancreatitis, 23 pancreatobiliary tract tumors (PBT) and 30 healthy controls (HC). PBMC (blood donors) were treated with insulin, EGF, TGFb1, S100A8/A9 before MMP8 and MMP9 mRNA analysis. Results: MMP8 and MMP9 were higher in PDAC and in PBT than in HC (Kruskal-Wallis test: P<0.0001). S100A8 (P=0.902) and S100A9 (P=0.303) did not vary. PDAC stage was not correlated with any molecule. At binary logistic regression analysis (PDAC presence or absence as dependent; S100A8, S100A9, MMP8, MMP9, age, gender, CA 19-9, bilirubin, glucose, C-peptide, CRP, and ALT as predictors), only MMP9 (OR=0.69; 95% CI: 0.48-0.99; P=0.047) and CA 19-9 (OR=1.74; 95% CI: 1.31-2.33; P=0.0002) were independently correlated with PDAC. In PDAC, DM was independently correlated only with S100A9 (OR=8.16; 95% CI: 2.31-28.78; P=0.001) and age (OR=1.10; 95% CI: 1.01-1.21; P=0.028). Insulin, EGF and TGFb1 did not affect MMP8 or MMP9 expression. S100A8/A9 significantly induced MMP8 (F=23.68; P=0.002) and MMP9 (F=93.84; P<0.0001) mRNA in PBMC. Conclusion PDAC is associated with an increased MMP9, while PDAC-associated DM is associated with an increased S100A9 expression in PBMC. S100A8/A9 effects on MMPs support the hypothesis of an intriguing relationship between inflammation, diabetes and PDAC.

description: Context EGFR overexpression occurs early, while loss of SMAD4 occurs in more advanced PDAC. Loss of SMAD4 alters TGFb1 signalling, associates with a reduced stromal and an increased cancer cell expression of S100A8/A9. Objective To ascertain whether the effects on NF-kB, Akt, mTOR and MAPK signalling pathways exerted by S100A8/A9, TGFb1 and EGF depend on SMAD4 deletion and whether they are sensitive to EGF chronic exposure. Methods BxPC3 (SMAD4 homozygous deletion) and SMAD4 expressing BxPC3 (BxPC3-SMAD4+; plasmid expression vector) were stimulated with EGF (100 ng/mL), S100A8/A9 (10 nM) and TGFb1 (0.02 ng/mL) alone or combined. Cells were both left untreated or were pre-treated with EGF for 3 days. Total protein lysates were used for the WB analysis of: Akt (Ser473, Thr308), mTOR (Ser2448, Ser2481), NF-kB (p-IkB-a), MAPK (p-p38, pErk 1/2). Results In BxPC3-SMAD4+ cells, EGF activated, while TGFb1 and S100A8/A9 inhibited Akt and MAPK. In these cells, S100A8/A9 and EGF stimulated, while TGFb1 inhibited NF-kB. SMAD4 deletion did not affect EGF signalling, reverted TGFb1 and S100A8/A9 effects on Akt, and allowed mTOR activation after TGFb1, S100A8/A9 and EGF treatments. EGF pre-treatment of BxPC3-SMAD4+ caused de-sensitization of NF-kB and MAPK to all stimuli, which inhibited Akt and activated mTOR. In the same conditions loss of SMAD4 caused NF-kB, MAPK and mTOR response to all stimuli. Only in BxPC3-SMAD4+ S100A8/A9 synergized with TGFb1 in inhibiting Akt. Conclusion SMAD4 deletion in pancreatic cancer cell and chronic treatment with EGF co-operate in activating pro-proliferative and pro-metastatic pathways when cells are treated with growth factors, inflammatory proteins and TGFb1.

description: We investigate the spectral zeta function of fractal differential operators such as the Laplacian on the unbounded (i.e., infinite) Sierpinski gasket and a self-similar Sturm-Liouville operator associated with a fractal self-similar measure on the half-line. In the latter case, C. Sabot discovered the relation between the spectrum of this operator and the iteration of a rational map of several complex variables, called the renormalization map. We obtain a factorization of the spectral zeta function of such an operator, expressed in terms of the Dirac delta hyperfunction, a geometric zeta function, and the zeta function associated with the dynamics of the corresponding renormalization map, viewed either as a polynomial function on the complex plane (in the first case) or (in the second case) as a polynomial on the complex projective plane. Our first main result extends to the case of the fractal Laplacian on the unbounded Sierpinski gasket a factorization formula obtained by the second author for the spectral zeta function of a fractal string and later extended by A. Teplyaev to the bounded (i.e., finite) Sierpinski gasket and some other decimable fractals. Furthermore, our second main result generalizes these factorization formulas to the renormalization maps of several complex variables associated with fractal Sturm-Liouville operators. Moreover, as a corollary, in the very special case when the underlying self-similar measure is Lebesgue measure on [0, 1], we obtain a representation of the Riemann zeta function in terms of the dynamics of a certain polynomial in the complex projective plane, thereby extending to several variables an analogous result by A. Teplyaev.

description: In this work a simple method to enforce the positivity-preserving property for general high-order conservative schemes is proposed. The method keeps the original scheme unchanged and detects critical numerical fluxes which may lead to negative density and pressure, and then imposes a cut-off flux limiter to satisfy a sufficient condition for preserving positivity. Though an extra time-step size condition is required to maintain the formal order of accuracy, it is less restrictive than those in previous works. A number of numerical examples suggest that this method, when applied on an essentially non-oscillatory base scheme, can be used to prevent positivity failure when the flow involves vacuum or near vacuum and very strong discontinuities.

description: Context Paragangliomas are rare neuroendocrine neoplasms arising from paraganglia of sympathetic trunk. Pancreatic localization is extremely rare (only 15 cases reported worldwide). Pancreatic paraganglioma has never been described before in the context of multiple endocrine neoplasia-1 (MEN 1) syndrome. Case report A 40-year-old male, known for previous follicular adenoma and primitive hyperparathyroidism, was admitted to our hospital with high blood pressure, flushing of the face, sweating and dysaesthesia of the lower limbs. Abdominal imaging showed multifocal pancreatic masses. He underwent total pancreatectomy with histological diagnosis of multifocal paraganglioma with a proliferative index (Ki67) of 10%. Further clinical evaluation evidenced pituitary microprolactinoma and adrenal hyper­plasia. Even in the absence of genetic mutation, a diagnosis of MEN 1 syndrome was clinically established. During follow-up he developed liver metastatic disease that was treated with targeted biological therapy and multiple lines of chemotherapy. Conclusion A clinical presentation of MEN syndrome in absence of definable gene mutation is possible and becoming a clinical challenge. We discuss here a pancreatic paraganglioma presenting with rapid growth and prone to metastasis dissemination in a clinically evident MEN 1 syndrome. Further studies are needed to understand genetic causes and biology of this rare type of neuroendocrine tumor.

description: Existing and planned optical telescopes and surveys can detect artificially-illuminated objects comparable in total brightness to a major terrestrial city out to the outskirts of the Solar System. Orbital parameters of Kuiper belt objects (KBOs) are routinely measured to exquisite precisions of <10^{-3}. Here we propose to measure the variation of the observed flux F from such objects as a function of their changing orbital distances D. Sunlight-illuminated objects will show a logarithmic slope alpha=(dlogF/dlog D)=-4 whereas artificially-illuminated objects should exhibit alpha=-2. Planned surveys using the proposed LSST will provide superb data that would allow measurement of alpha for thousands of KBOs. If objects with alpha=-2 are found, follow-up observations can measure their spectra to determine if they are illuminated by artificial lighting. The search can be extended beyond the Solar System with future generations of telescopes on the ground and in space, which would be capable of detecting phase modulation due to very strong artificial illumination on the night-side of planets as they orbit their parent stars.

The effect of surface topography on gene expression of macrophages
Creators: name: Wong, Angela Ting Ting
Publisher: name: University of British Columbia

description: Osseointegration, the direct attachment of living bone to an implant surface, is necessary for the success of dental implant therapy. The surface topography of an implant influences cellular behaviour and osseointegration. In-vivo studies have shown that rough surface topographies are associated with accumulation of macrophages and subsequent bone formation (Chehroudi et al., 2009). Macrophages can exhibit classic inflammatory (M1) or alternative (M2) phenotypes that secrete different patterns of cytokines, chemokines and growth factors that affect wound healing. These experiments aim to characterize the phenotypes of unstimulated RAW264.7 macrophages grown on polished and SLA (sandblasted and acid-etched) surfaces using gene expression microarray technology. Whole genome microarray analysis showed differential expression of 199 genes on day 1 and 4943 genes on day 5 on SLA compared to polished surfaces. These genes were assigned to network categories related to cellular movement, immune cell trafficking, inflammation, cell-to-cell signalling and tissue development. Gene profiles were also compared to M1 and M2 macrophages obtained by stimulation with LPS and IL-4 respectively. Stimulated macrophages exhibited gene expression profiles consistent with their predicted phenotypes. Confirmation of upregulated expression of CCL4 and CCL7, macrophage chemoattractants associated with early inflammatory responses, was performed with quantitative real time polymerase chain reaction (qPCR). CCL4 was significantly upregulated on SLA surfaces by a factor of 2.18 after 1 day, and CCL7 was significantly upregulated on SLA surfaces by a factor of 4.01 after 5 days. Both CCL4 and CCL7 were also significantly upregulated after 1 day by M1 and M2 stimulated macrophages on the microarray. These experiments show that unstimulated macrophages grown on SLA surfaces increase gene expression of macrophage chemoattractants, and exhibit an intermediate phenotype with a mixture of M1 and M2 characteristics.

description: We examine to what extent the inferred surface temperature of magnetars in quiescence can constrain the presence of a superfluid in the neutron star core and the role of magnetic field decay in the core. By performing detailed simulations of neutron star cooling, we show that extremely strong heating from field decay in the core cannot produce the high observed surface temperatures nor delay the onset of neutron superfluidity in the core. We verify the results of Kaminker et al., namely that the high magnetar surface temperatures require heating in the neutron star crust, and crust heating is decoupled from cooling/heating in the core. Therefore, because crust heating masks core heating, it is not possible to conclude that magnetar cores are in a non-superfluid state purely from high surface temperatures. From our interior temperature evolutions and after accounting for proton superconductivity in the core, we find that neutron superfluidity in the core occurs less than a few hundred years after neutron star formation. This onset time is unaffected by heating due to core field decay at fields < 10^16 G. Thus all known neutron stars, including magnetars, without a core containing exotic particles, should have a core of superfluid neutrons and superconducting protons.

This equation is also derived in the framework of a tangent bundle. By using Cartan or Berwald-like connections we get some types "gravito - electromagnetic" curvature. In addition we investigate the conditions under which a definite Lagrangian in a Randers space leads to Einstein field equations under the presence of electromagnetic field. Finally, some applications of the weak field in a generalized Finsler spacetime for gravitational waves are given.

description: Context Stimulating the patient’s immune system to attack malignant tumor cells is considered a promising alternative therapeutic strategy to treat pancreatic adenocarcinoma (PDAC). Recent data point to the neogenesis of organized and vascularized ectopic (or tertiary) lymphoid tissue (TLT) at the tumor site, where B and T cell responses are efficiently initiated and sustained. Objective To investigate the occurrence of TLT in human PDAC and test whether a protocol of immunotherapy induces formation of TLT in a PDAC murine model. This might represent an alternative approach to target the tumor stroma, by creating a lymphoid like microenvironment, to increase the recruitment and activation of T cells. Methods Occurrence of TLT was evaluated by immunohistochemistry in PDAC tissue specimens from consecutive patients who underwent surgical resection at the Humanitas Clinical and Research Centre. A dendritic-cell (DC) based vaccine was used to immunize mice injected with Panc02 murine cells. Results In human PDAC tissue specimens, we identified organized lymphoid tissue, including compartmentalized T and B cell areas, DCs and high endothelial venules (HEV). In the heterogeneity of PDAC tissue, TLT occurred preferentially in the stromal compartment. The density of TLT correlated to the density of intra-tumor CD8 T cells, which displayed a phenotype indicating a defective activation status. In a murine model of PDAC, vaccination with DCs loaded with apoptotic PDAC cells occasionally induced formation of TLT. Conclusion Here we report the occurrence of lymphoid tissue in human PDAC, in the context of the desmoplastic stromal reaction and the correlation with CD8+ T cell infiltration. Immunotherapeutic approaches might induce formation of TLT and be exploited as alternative strategies to modify PDAC stroma and induce an anti-tumor immune response.

description: Context A long-standing increase of serum pancreatic enzymes in asymptomatic subjects is considered a benign idiopathic condition called “non-pathological chronic pancreatic hyper­enzymemia” (CPH). However, recent studies showed secretin-MRCP (s-MRCP) has brought to light abnormal pancreatic findings in a significant proportion of these subjects. Objective To evaluate pancreatic morphological abnormalities using s-MRCP and EUS in CPH patients. Methods Consecutive patients affected by CPH were investigated with s-MRCP and EUS. EUS findings were compared with consecutive age- and sex-matched controls who underwent EUS investigation for unrelated to pancreaticobiliary disease (CTR). Results Fifty-five CPH subjects and 55 CTR patients were enrolled. Abnormal s-MRCP pancreatic findings were present in 23 CPH cases (41.8%): 10 chronic pancreatitis, according to Cambridge classification; 5 pancreas divisum; 3 pancreatic cyst; 5 Vater’s papilla dysfunction. Pathological EUS pancreatic findings were present in 28 CPH cases (50.9%): 7 pancreatic cystic lesion, 5 pancreas divisum, 1 papillitis, 1 NET, 14 chronic pancreatitis (CP) defined by presence of “consistent with CP” or “suggestive of CP” findings using Rosemont criteria. All cases of CP who undergone s-MRCP had pathological EUS findings suggestive for CP too. Normal EUS findings were more significantly frequent in control patients (n=45) than CPH patient (n=27) (P<0.05). The two groups have same frequencies in detection of cystic lesions, pancreas divisum, papillitis, NET, but chronic pancreatitis was more common in CPH (25.5% vs. 7.3%; P<0.05). Conclusions About half of the patients with asymptomatic chronic pancreatic hyper­enzymemia had some pancreatic abnormalities using s-MRCP and EUS. Both these procedures should characterize the diagnostic work-up of these subjects before the hyperenzymemia can be defined with certainly as non-pathological or benign.

description: Context The diagnosis of autoimmune pancreatitis (AIP) is based on a combination of pancreatic histology, imaging, serology, other organ involvement, and response to steroids. In this setting, endoscopic ultrasound (EUS) is considered the procedure of choice to obtain pancreatic tissue in order to establish the diagnosis and/or to exclude malignancy. However, negative cytology or histology obtained by EUS-FNA does not exclude AIP. In order to further investigate these subgroups of patients, there are two promising imaging tools: real-time EUS elastography of the pancreas and contrast-enhanced EUS. Objective and methods To evaluate the diagnostic yield of EUS in detection of AIP by comparing EUS findings with standard radiological imaging (CT and/or MRI) in patients with suspected autoimmune disease referred to our tertiary center. Results Thirty-two patients with radiological suspicious of AIP underwent EUS. Focal enlargement of pancreatic parenchyma and focal narrowing of main pancreatic duct (MPD) were detected in the same way by MRI and EUS, being both techniques better that CT (12/21, 12/32, and 7/19, respectively). Diffuse pancreatic parenchyma enlargement and detection of multiple stricture of MPD were better identified by EUS (8/19 with CT, 3/21 with RMN, 12/32 with EUS; 1/19 with CT, 1/21 with RMN, 6/32 with EUS, respectively). Focal and diffuse AIP presented hypervascularization pattern after contrast agent injection in the majority of patients (10/13). At elastography, focal AIP presented with a pattern of small spotted mainly blue colour signals that are evenly spread, showing a different pattern from pancreatic cancer. In addition, when targeted masses were unclear on fundamental B-mode EUS imaging, elastography was useful to find the targeted area to biopsy. Conclusion We believe that EUS elastography and contrast-enhanced EUS alone or in combination are promising tools in the diagnostic approach of focal AIP. It seems that in the near future their use might be integrated in the diagnostic algorithms of AIP.

description: Let ${\mathscr P}$ be a topological property. We say that a space $X$ is ${\mathscr P}$-connected if there exists no pair $C$ and $D$ of disjoint cozero-sets of $X$ with non-${\mathscr P}$ closure such that the remainder $X\backslash(C\cup D)$ is contained in a cozero-set of $X$ with ${\mathscr P}$ closure. If ${\mathscr P}$ is taken to be "being empty" then ${\mathscr P}$-connectedness coincides with connectedness in its usual sense. We characterize completely regular ${\mathscr P}$-connected spaces, with ${\mathscr P}$ subject to some mild requirements. Then, we study conditions under which unions of ${\mathscr P}$-connected subspaces of a space are ${\mathscr P}$-connected. Also, we study classes of mappings which preserve ${\mathscr P}$-connectedness. We conclude with a detailed study of the special case in which ${\mathscr P}$ is pseudocompactness. In particular, when ${\mathscr P}$ is pseudocompactness, we prove that a completely regular space $X$ is ${\mathscr P}$-connected if and only if $cl_{βX}(βX\backslash\upsilon X)$ is connected, and that ${\mathscr P}$-connectedness is preserved under perfect open continuous surjections. We leave some problems open.

description: The present article is part of a research program the aim of which is to find all indecomposable solvable extensions of a given class of nilpotent Lie algebras. Specifically in this article we consider a nilpotent Lie algebra n that is isomorphic to the nilradical of the Borel subalgebra of a complex simple Lie algebra, or of its split real form. We treat all classical and exceptional simple Lie algebras in a uniform manner. We identify the nilpotent Lie algebra n as the one consisting of all positive root spaces. We present general structural properties of all solvable extensions of n. In particular, we study the extension by one nonnilpotent element and by the maximal number of such elements. We show that the extension of maximal dimension is always unique and isomorphic to the Borel subalgebra of the corresponding simple Lie algebra.

Do liquid drops roll or slide on inclined surfaces?

description: We study the motion of a two-dimensional droplet on an inclined surface, under the action of gravity, using a diffuse interface model which allows for arbitrary equilibrium contact angles. The kinematics of motion is analysed by decomposing the gradient of the velocity inside the droplet into a shear and a residual flow. This decomposition helps in distinguishing sliding versus rolling motion of the drop. Our detailed study confirms intuition, in that rolling motion dominates as the droplet shape approaches a circle, and the viscosity contrast between the droplet and the ambient fluid becomes large. As a consequence of kinematics, the amount of rotation in a general droplet shape follows a universal curve characterised by geometry, and independent of Bond number, surface inclination and equilibrium contact angle, but determined by the slip length and viscosity contrast. Our results open the way towards a rational design of droplet-surface properties, both when rolling motion is desirable (as in self-cleaning hydrophobic droplets) or when it must be prevented (as in insecticide sprays on leaves).

description: We explore heavy element nucleosynthesis in the explosion of massive stars which are triggered by a quark-hadron phase transition during the early post bounce phase of core-collapse supernovae. The present study is based on general relativistic radiation hydrodynamics simulations with three-flavor Boltzmann neutrino transport in spherical symmetry, which utilize a quark-hadron hybrid equation of state based on the MIT bag model for strange quark matter. The quark-hadron phase transition inside the stellar core forms a shock wave propagating towards the surface of the proto-neutron star. The shock wave results in an explosion and ejects neutron-rich matter which is piled up or accreting on the proto-neutron star. Later, during the cooling phase, the proto-neutron star develops a proton-rich neutrino-driven wind. We present a detailed analysis of the nucleosynthesis outcome in both neutron-rich and proton-rich ejecta and compare our integrated nucleosynthesis with observations of metal poor stars.

Splenic Vein Aneurysm Mimicking Endocrine Pancreatic Tumor

description: Context Splenic vein aneurysm (SVA) is an extremely rare vascular abnormality, and is usually caused by portal hypertension. Symptoms are unusual, but may include rupture or abdominal pain. Diagnosis is usually made by duplex ultrasonography or computed assisted tomography: detection by magnetic resonance is infrequent. Due to a rarity of this pathology, treatment is unclear, and varies from non-invasive follow-up to surgical excision. Case report A 60-year-old man with a 14-year history of ulcerative colitis, presented with a 3-month history of ischemic artery disease of the right leg. CT angiography showed stenosis of the right, external femoral artery, and a 1 cm solid, hypervascular lesion in the body of the pancreas. Magnetic resonance imaging (MRI) confirmed a 17 mm nodule in the pancreatic body, near to splenic vein. A suspicion of endocrine tumor of the pancreas was made, and the patient was referred to our department 5 months later. A PET/TC with Ga68 (DOTATOC) failed to show any pathologic uptake of the radiotracer. Serum hormonal assays were in the normal range. The patient underwent abdominal MRI that showed a 1 cm lesion of the body of the pancreas with the same signal intensity of the splenic vein. Abdominal CT angiography revealed a 20x17 mm splenic vein ectasia. No neoplasms were detected into the pancreatic parenchyma either by CT or MRI; no abnormal findings in the portal or superior mesenteric veins were found. A follow-up with color Doppler ultrasonography or MRI was scheduled and after six months the patient is well: there was no change in the size or number of SVA. Conclusion Because the incidence of SVA is very low, the exact indication for intervention and the type of treatment is not well defined. Although follow-up is limited, as in our case, in asymptomatic patients with small aneurysms, observation and careful follow-up appear to be sufficient treatment. So, at this moment, each case must be individually evaluated.

Nonparametric estimation of the jump rate for non-homogeneous marked renewal processes

description: This paper is devoted to the nonparametric estimation of the jump rate and the cumulative rate for a general class of non-homogeneous marked renewal processes, defined on a separable metric space. In our framework, the estimation needs only one observation of the process within a long time. Our approach is based on a generalization of the multiplicative intensity model, introduced by Aalen in the seventies. We provide consistent estimators of these two functions, under some assumptions related to the ergodicity of an embedded chain and the characteristics of the process. The paper is illustrated by a numerical example.
