description: We consider two possible mechanisms for single-vortex fluctuative entry/exit through the surface barrier in ultrathin superconducting disk-shaped nanoislands made of Pb and consisting of just few monoatomic layers, which can be fabricated using modern techniques. We estimate tunnelling probabilities and establish criteria for the crossover between these two mechanisms depending on magnetic field and system sizes. For the case of vortex entry, quantum tunnelling dominates on the major part of the temperature/flux phase diagram. For the case of vortex exit, thermal activation turns out to be more probable. This nontrivial result is due to the subtle balance between the barrier height and width, which determine rates of the thermal activation and quantum tunneling, respectively.

description: Context Insulinoma is the most common endocrine tumor of the pancreas. Over 90% of insulinomas are benign, single and evenly distributed in head, body and tail of the pancreas. Depending on the location, they can be enucleated or may require partial pancreatectomy. Objective To evaluate histological features, type of surgery, early complications (within 30 days) and prognosis. Methods We reviewed clinical data of patients observed for organic hyperinsulinism from January 1966 to December 2010 in our Department (follow up to December 2011). Results From 1966 to 2010 we observed 102 patients with organic hyperinsulinism (60 females and 42 males averaging 49.5 years). We had 7 cases of hyperplasia/ nesidioblastosis, 7 multiple tumors and 7 malignant insulinomas. Localization: 32 pancreatic head, 8 neck, 21 body, 33 tail, 5 whole pancreas, 1 left ovary and 2 unknown. Surgery: 39 enucleations, 38 distal pancreatectomies, 6 central pancreatectomies, 3 DPPHR, 2 pancreaticoduodenectomies, 4 total/subtotal pancreatectomies, 3 other surgery. Perioperative mortality was 5% (3 acute pancreatitis, 1 stroke, 1 disseminated intravascular coagulation). Perioperative morbidity was 23% (3 acute pancreatitis, 13 pancreatic fistulas, 4 abdominal abscesses, 2 pseudocysts, 1 biliary leakage). In 5 cases a second operation was necessary. Excluding malignant cases, postoperative deaths and not operated cases, 86/88 patients were cured after surgery and we had 2 cases of persistent hypoglycemia (1 hyperplasia, 1 not found). After a mean follow up of 212 months (89 patients included), 64/89 are still alive and free of disease. Among the dead patients, 3/23 died of disease progression. Among 7 malignant cases, 2/7 with lymph node metastases had a survival of 167 and 388 months after resection of the primary tumor and nodes. The median survival of the 5/7 not resected was 12 months. Conclusion Surgical treatment of insulinomas can be challenging and in some cases is still associated to mortality (5%). A high rate of surgical success (98%) was obtained with 5% of reoperation.

description: Context SNPs in the telomerase reverse transcriptase (TERT) locus were reported to be associated with pancreatic cancer risk in a genome-wide association study (GWAS). TERT is essential for maintaining telomere ends. Its over-expression in normal cells can lead to prolonged cell lifespan and transformation. While telomerase activity cannot be detected in most normal tissues, it is seen in approximately 90% of human cancers. Objective We attempted to replicate and expand the association with the locus in a series of PDAC and healthy controls of European ancestry within the PANcreatic Disease ReseArch (PANDoRA) consortium. Methods We genotyped 13 SNPs in 1,034 PDAC cases and 2,443 controls from the PANDoRA consortium. We tested each SNP for association with PDAC risk and also with survival of the patients. Results We replicated the association reported in the GWAS with rs401681 (OR=1.53; 95%C;I 1.22-1.92; P=0.0002) and found a novel association between rs2736098 and decreased PDAC risk (OR=0.75; 95%CI: 0.63-0.88; P=0.001). Another polymorphism (rs4246742) was associated with worse survival (HR=1.75, 95%CI: 1.15-2.67; P=0.009). Conclusion We report here two novel findings: an association with risk (rs2736098) and one with survival of the patients (rs4246742). These results further contribute to our understanding in the genetic etiology of pancreatic cancer and suggest a new marker for disease prognosis.

description: In this work, we study six tree-dominated $B \to a_1(1260) a_1(1260)$ and $b_1(1235) b_1(1235)$ decays in the perturbative QCD(pQCD) approach, where $a_1$($b_1$) is a $^3P_1$($^1P_1$) axial-vector meson. Based on the perturbative calculations and phenomenological analysis, we find that: (a) the CP-averaged branching ratio of $B^0 \to a_1^+ a_1^-$ decay in the pQCD approach is $54.7 \times 10^{-6}$, which agrees well with the current data and the predictions given in the QCD factorization approach within errors; (b) the numerical results for the decay rates of other five channels are found to be in the order of $10^{-6} \sim 10^{-5}$, which could be accessed at B factories and Large Hadron Collider(LHC) experiments; (c) other physical observables such as polarization fractions and direct CP-violating asymmetries are also investigated with the pQCD approach in the present work and the predictions can be confronted with the relevant experiments in the near future; (d) the different phenomenologies shown between $B \to a_1 a_1$ and $B \to b_1 b_1$ decays are expected to be tested by the ongoing LHC and forthcoming Super-B experiments, which could shed light on the typical QCD dynamics involved in these decay modes, as well as in $^3P_1$ meson $a_1$ and $^1P_1$ meson $b_1$.

description: The majority of eukaryotic protein-coding genes contain low complexity regions (LCRs), which serve as a distinct source of adaptive variation, functional diversification, and evolutionary novelty. The intricate governance of low complexity regions (LCRs) involves the interplay of selection and mutation dynamics, necessitating a more comprehensive understanding of their complex interdependence. Our investigation demonstrates that positively-selected sites (PSS) and low complexity regions (LCRs) are predominantly located in terminal gene regions across most Tetrapoda clades. In seven of the twelve clades studied, PSS are notably favored within LCRs, revealing a positional specificity for PSS within genes. Central-PSS genes are mainly associated with defense responses, while terminal-PSS genes serve non-specific functions. Furthermore, genes with LCRs in the Tetrapoda clade exhibit a higher %GC and lower ω (dN/dS) compared to those without LCRs, indicating intense purifying selection despite rapid functional diversity. Our findings highlight a consistent prevalence of LCRs at lower purity levels, with a clear preference for specific gene positions as LCR stretch purity increases, suggesting a composition-dependent evolutionary role. Overall, these results significantly contribute to our understanding of how the intricate interplay between selection and LCRs shapes genetic diversity and adaptation within the Tetrapoda clade.

description: This paper focuses on the activities of house dealers or agents in the Gusau metropolis while also analyzing their operations to evaluate their compliance with the Islamic Shari’ah principles. The finding of this research shows that the agent activities in Gusau metropolis are solely on their role to market and promote the products as most of the agents needs to know the basic concept of agency or Wakalah in Islam and which will make them act more by principles of Islam in their day to day business activities. The paper concludes that the agency system should be further strengthened as it has an important role in the house sales or renting business. Indirectly, it can enhance the development of the Islamic system of business in the Gusau metropolis as well as make it known to the society that it is a good system and can completely be translated to the Islamic method of business if the laws applicable to were adopted. A qualitative method was used in this research which is based on library research, reference to many books, articles, proceeding papers, handouts, journals, internet sources and interviews

description: Nanothermochromic diffraction gratings based on the metal-insulator transition of $\mathrm{VO_2}$ are fabricated by site-selective ion beam implantation in a $\mathrm{SiO_2}$ matrix. Gratings were defined either (i) directly by spatially selective ion beam synthesis or (ii) by site-selective deactivation of the phase transition by ion beam induced defects. The strongest increase of the diffracted light intensities was observed at a wavelength of 1550\,nm exceeding a factor of 20 for the selectively deactivated gratings. The observed pronounced thermal hysteresis extending down close to room temperature makes this system ideally suited for optical memory applications.

description: Context Several early studies reported an association between AB0 blood type and pancreatic cancer risk. A genome-wide association study (GWAS) recently reported association between SNPs at the AB0 locus and pancreatic cancer risk. Objective We attempted to replicate and expand the association with the locus in a series of PDAC and healthy controls of European ancestry within the PANcreatic Disease ReseArch (PANDoRA) consortium. Methods We genotyped 6 functional SNPs enabling the prediction the AB0 blood groups in 1,028 PDAC cases and 2,252 controls from the PANDoRA consortium. We tested each SNP and the predicted blood type for association with PDAC risk and also assessed whether the risk SNPs and blood types have an impact on survival of the patients. Results We replicated the association reported in the GWAS with rs505922 (OR=1.18; 95% CI: 1.001-1.39; P=0.048). We also confirmed the associations with blood group A (OR=1.24: 95% CI: 1.04-1.48; P=0.015), and in particular with subgroup A1. We do not find association with blood groups B and AB. We did not find any statistically significant association between SNPs in AB0 or blood group and survival or different staging of cancer. Conclusion AB0 alleles corresponding to increased glycosyltransferase activity were associated with increased pancreatic cancer risk.

description: We consider the simplest example of lattice frustration in the 1/4-filled band, a one-dimensional chain with next-nearest neighbor interactions. For this zigzag ladder with electron-electron as well as electron-phonon interactions we present numerical results for ground state as well as thermodynamic properties. In this system the ground state bond distortion pattern is independent of electron-electron interaction strength. The spin gap in the ground state of the zigzag ladder increases with the degree of frustration. Unlike in one-dimension, where the spin-gap and charge ordering transitions can be distinct, we show that in the ladder they occur simultaneously. We discuss spin gap and charge ordering transitions in 1/4-filled materials with one, two, or three dimensional crystal structures. We show empirically that regardless of dimensionality the occurrence of simultaneous or distinct charge and magnetic transitions can be correlated with the ground state bond distortion pattern.

description: In an expanding universe the vacuum energy density ρ_Λ is expected to be a dynamical quantity. In quantum field theory in curved space-time ρ_Λ should exhibit a slow evolution, determined by the expansion rate of the universe H. Recent measurements on the time variation of the fine structure constant and of the proton-electron mass ratio suggest that basic quantities of the Standard Model, such as the QCD scale parameter Λ_{QCD}, may not be conserved in the course of the cosmological evolution. The masses of the nucleons m_N and of the atomic nuclei would also be affected. Matter is not conserved in such a universe. These measurements can be interpreted as a leakage of matter into vacuum or vice versa. We point out that the amount of leakage necessary to explain the measured value of \dot{m}_N/m_N could be of the same order of magnitude as the observationally allowed value of \dotρ_Λ/ρ_Λ, with a possible contribution from the dark matter particles. The dark energy in our universe could be the dynamical vacuum energy in interaction with ordinary baryonic matter as well as with dark matter.

CD44 and hyaluronan binding in macrophages and dendritic cells
Creators: name: Poon, Grace Fong-Ting
Publisher: name: University of British Columbia
Year: 2014

description: Hyaluronan is a glycosaminoglycan present in pericellular and extracellular matrices. Hyaluronan production and binding are tightly regulated during an immune response yet its effects on immune cells, particularly macrophages and dendritic cells, are not fully understood. CD44 is the major surface receptor for hyaluronan, but not all CD44-expressing cells have the ability to bind hyaluronan. Here I demonstrate that hyaluronan binding is dynamically regulated during macrophage activation as well as dendritic cell differentiation, and CD44 provides macrophages with a selective advantage in the alveolar space that correlates with hyaluronan binding. Inflammatory macrophages activated with lipopolysaccharide plus interferon gamma bound higher levels hyaluronan compared to alternatively activated macrophages polarized with interleukin 4 by modifying chondroitin sulfation on CD44, and these macrophages differ in their ability to take up hyaluronan. In GM-CSF bone marrow-derived dendritic cell cultures, hyaluronan binding identified an immature population that was CD11c+ MHC IImid/low, highly proliferative and did not mature into MHC IIhigh cells. The removal of hyaluronan with hyaluronidase inhibited proliferation of the hyaluronan binding cells and promoted the maturation of dendritic cells. Furthermore, the hyaluronan binding cells had several macrophage characteristics and were retained in the alveolar space while the MHC IIhigh, low hyaluronan binding dendritic cells migrated to the lymph node upon inflammation. These results suggest a role for hyaluronan in cell proliferation and retention in the alveolar space. In vivo, peritoneal, splenic and lung interstitial macrophages bound low or no detectable levels of hyaluronan whereas alveolar macrophages constitutively bound high levels of hyaluronan. The alveolar space promoted hyaluronan binding, as instillation of peritoneal macrophages into the lung upregulated their ability to bind hyaluronan. During lung inflammation, the hyaluronan binding population in the alveolar space was initially reduced and then restored upon resolution as a result of macrophage proliferation. In competition assays, CD44 provided hyaluronan binding macrophages with an advantage in the alveolar space. Collectively, this study reveals a novel role for CD44 in the maintenance of macrophages in the alveolar space and suggests that hyaluronan binding is induced at GM-CSF rich environments to help retain tissue macrophages at the site and promote their self-renewal.

description: We derive an analytical expression for the distribution of the k-th smallest Dirac eigenvalue in QCD with imaginary isospin chemical potential in the Dirac operator. Because of its dependence on the pion decay constant F through the chemical potential in the epsilon-regime of chiral perturbation theory this can be used for lattice determinations of that low-energy constant. On the technical side we use a chiral Random-Two Matrix Theory, where we express the k-th eigenvalue distribution through the joint probability of the ordered k smallest eigenvalues. The latter can be computed exactly for finite and infinite N, for which we derive generalisations of Dyson's integration Theorem and Sonine's identity.

Gravitational Waves from Quasicircular Extreme Mass-Ratio Inspirals as Probes of Scalar-Tensor Theories

description: A stellar-mass compact object spiraling into a supermassive black hole, an extreme-mass-ratio inspiral (EMRI), is one of the targets of future gravitational-wave detectors and it offers a unique opportunity to test General Relativity (GR) in the strong-field. We study whether generic scalar-tensor (ST) theories can be further constrained with EMRIs. We show that in the EMRI limit, all such theories universally reduce to massive or massless Brans-Dicke theory and that black holes do not emit dipolar radiation to all orders in post-Newtonian (PN) theory. For massless theories, we calculate the scalar energy flux in the Teukolsky formalism to all orders in PN theory and fit it to a high-order PN expansion. We derive the PN ST corrections to the Fourier transform of the gravitational wave response and map it to the parameterized post-Einsteinian framework. We use the effective-one-body framework adapted to EMRIs to calculate the ST modifications to the gravitational waveform. We find that such corrections are smaller than those induced in the early inspiral of comparable-mass binaries, leading to projected bounds on the coupling that are worse than current Solar System ones. Brans-Dicke theory modifies the weak-field, with deviations in the energy flux that are largest at small velocities. For massive theories, superradiance can lead to resonances in the scalar energy flux that can lead to floating orbits outside the innermost stable circular orbit and that last until the supermassive black hole loses enough mass and spin-angular momentum. If such floating orbits occur in the frequency band of LISA, they would lead to a large dephasing (~1e6 rads), preventing detection with GR templates. A detection that is consistent with GR would then rule out floating resonances at frequencies lower than the lowest observed frequency, allowing for the strongest constraints yet on massive ST theories.

description: Rotated graphene multilayers form a new class of graphene related systems with electronic properties that drastically depend on the rotation angles. It has been shown that bilayers behave like two isolated graphene planes for large rotation angles. For smaller angles, states in the Dirac cones belonging to the two layers interact resulting in the appearance of two van Hove singularities. States become localised as the rotation angle decreases and the two van Hove singularities merge into one peak at the Dirac energy. Here we go further and consider bilayers with very small rotation angles. In this case, well defined regions of AA stacking exist in the bilayer supercell and we show that states are confined in these regions for energies in the [-γ_t, +γ_t] range with γ_t the interplane mean interaction. As a consequence, the local densities of states show discrete peaks for energies different from the Dirac energy.

description: Context Among the patients with mild acute biliary pancreatitis (ABP), without an increase of cholestasis indexes neither dilation of the intra-extra-hepatic biliary ducts, literature data show a variable range (45-75%) of common bile duct (CBD) stones carriers. It is useful to know if obstacles are present in the CBD. Objective To verify the sensibility of MRCP to determine the conditions of the CBD before the cholecystectomy. Methods Thirty-five patients with mild ABP (Glasgow score = 1) were studied in the period from January 2007 to February 2012; the diagnosis of ABP was made on the basis of the clinical symptoms, the laboratory data and the US instrumental data for the confirmation of the biliary etiology. All patients were submitted to an MRCP. Results MRCP was diagnostic for choledocholithiasis in 10 patients (28.6%) that were submitted to an ERCP/ES with radiologic and endoscopic confirmation of the presence of stones/sludge in the CBD with a complete clearance. During the same hospital stay, all the patients were submitted to cholecystectomy and no patients had a relapse of the acute pancreatitis. Conclusion MRCP seems to be the gold standard technique to be utilized in all patients with mild ABP avoiding ERCP/ES in patients without predictive factors of choledocholithiasis.

description: Context Acute biliary pancreatitis (ABP) is caused by alteration of the papillary patency. Objective Normal transpapillar flux and cleaning of the common biliary duct (CBD) may prevent potentially avoidable recurrent pancreatitis. Methods In the period from September 1999 to December 2011 we treated 276 ABP (60 severe, 216 mild/moderate): 188 (72%) with first attack and 73 (28%) with recurrent ABP (second or further attack). Patients with recurrent pancreatitis had not undergone, in previous hospital stay elsewhere, the evaluation and, if necessary, treatment of papillary obstacle and/or CBD stones or sludge. In our hospital all patients underwent the treatment of ABP completed with cholecystectomy. All patients, after discharge, were introduced in a follow-up program (clinical and US control) after 180 days and 1 year. Results In the follow-up of recurrent pancreatitis we controlled 42 patients (57%; 31 lost). Follow-up results showed, beside the absence of recurrent acute episodes, stable normalization of laboratory cholestasis tests and US control. The same controls in 90 patients (48%) with a first attack of acute pancreatitis resulted normal in absence of a new acute episode. Conclusions Recurrent ABP is caused by persistent papillary obstacle. Therefore, we confirm therapeutic validity of instrumental control (US/MRCP) and possible treatment of papillary or biliary lithiasis obstacle for prevention of recurrent ABP.

description: Context Severe acute biliary pancreatitis is about 20% of all the pancreatitis. The relapse of the untreated cases is >20%. Objective The aim of the study is to define a mininvasive approach of the SABP: the maintenance of papillary patency and the treatment of the peripancreatic fluid gatherings and of the gallstones. Patients and Methods In the period 1999-2011, 60 severe acute biliary pancreatitis were treated: 42 necrotizing cases and 18 cases with pancreatic edema. All patients underwent ERCP/ES within 72 hours; it was successfully executed in 50 cases, in 7 cases it was delayed of 10 days, and it was non practicable in 3 cases. CT-scan guided percutaneous drainage was used for 3 infected peripancreatic and 2 intrahepatic gathering; another 2 infected gatherings were drained by laparotomic access. Cholecystectomy within 30 days: laparoscopic in 56 patients (93%). Results There were 4 post-ERCP pancreatitis (6.6%), failure of the procedure in 3 cases (5%) and no cholangitis, hemorrages or duodenal perforations; no morbidity for cholecystectomy neither for percutaneous drainage with resolution within 10 days. One patient (1.6%) died in 20th day because of DIC. Conclusions The mininvasive approach of the severe acute biliary pancreatitis is an efficacious and safe therapeutic program with a long period of resolution (mean 35 days) but satisfying for the results.

description: Unitary control of qudits can improve the collective spin squeezing of an atomic ensemble. Preparing the atoms in a state with large quantum fluctuations in magnetization strengthens the entangling Faraday interaction. The resulting increase in interatomic entanglement can be converted into metrologically useful spin squeezing. Further control can squeeze the internal atomic spin without compromising entanglement, providing an overall multiplicative factor in the collective squeezing. We model the effects of optical pumping and study the tradeoffs between enhanced entanglement and decoherence. For realistic parameters we see improvements of ~10 dB.

Biochemical characterization and regulation of transcription of Polycomb Group RING Finger 5
Creators: name: Cochrane, Christopher Larson
Publisher: name: University of British Columbia
Year: 2013

description: The Polycomb Group (PcG) is a highly conserved group of genes which serve to repress transcription via specific modifications of histones in chromatin. The PcG has well-established roles in development and is involved, by mutation or dysregulation, in many human diseases including cancer. This study identifies the gene PCGF5, which is a paralogue of the oncogene Bmi1, as a transcriptional target of Notch signalling in T cell acute lymphoblastic leukemia (T-ALL). Evidence suggests that this regulation is direct and that the Notch transactivation complex binds DNA at several regions near the PCGF5 gene. PCGF5 is found to be expressed at a higher level in T-ALL than other hematopoietic malignancies. PCGF5 is found to associate with the PcG proteins RING1A and RING1B and its overexpression results in increased ubiquitylation of histone H2A, suggesting it shares functional similarity to Bmi1. Despite their similarities, Bmi1 and PCGF5 have a different spectrum of binding partners and are targeted to different locations in the genome. Overexpression of PCGF5 does not significantly alter hematopoietic development in vivo; however, enforced expression of PCGF5 in bone marrow progenitors results in the generation of fewer colonies in a myeloid colony forming assay. This study suggests that PCGF5 may have as yet unappreciated roles in PcG biology and merits further study into its effects on development and hematopoietic neoplasia.
Spin-Orbital Locking, Emergent Pseudo-Spin, and Magnetic order in Honeycomb Lattice Iridates

description: The nature of the effective spin Hamiltonian and magnetic order in the honeycomb iridates is explored by considering a trigonal crystal field effect and spin-orbit coupling. Starting from a Hubbard model, an effective spin Hamiltonian is derived in terms of an emergent pseudo-spin-1/2 moment in the limit of large trigonal distortions and spin-orbit coupling. The present pseudo-spins arise from a spin-orbital locking and are different from the jeff = 1/2 moments that are obtained when the spin-orbit coupling dominates and trigonal distortions are neglected. The resulting spin Hamiltonian is anisotropic and frustrated by further neighbour interactions. Mean field theory suggests a ground state with 4-sublattice zig-zag magnetic order in a parameter regime that can be relevant to the honeycomb iridate compound Na2IrO3, where similar magnetic ground state has recently been observed. Various properties of the phase, the spin-wave spectrum and experimental consequences are discussed. The present approach contrasts with the recent proposals to understand iridate compounds starting from the strong spin-orbit coupling limit and neglecting non-cubic lattice distortions.

description: Context Dermoid cysts are congenital developmental abnormalities of germ cell origin arising from embryonic residues and they are usually benign, well-differentiated lesions. They are commonly found in the ovary, testes and retroperitoneum; the pancreas is extremely rare as a primary site. Case report A 68-year-old woman presented a cystic lesion (4 cm) of the pancreatic tail as an incidental finding at a MR scan performed for other reasons. A CT scan confirmed the tail lesion, which had a lamellar calcification on the posterior wall. A 18FDG-PET was negative. Laboratory examination showed normal values, including CEA and CA 19-9. Because of the size of the lesion and the risk of malignancy, the patient underwent a spleen-preserving distal pancreatectomy. Histology showed a squamoid cyst (3 cm) of the pancreatic ducts. It was unilocular and had serous content and fibrous wall, with multilayered epithelium without cytological atypias (immunehistochemistry: CK7 positive and CK5 negative). The post-operative course was uneventful, but the patient was readmitted a few days after discharge for abdominal pain due to a peripancreatic fluid collection. She was treated with a percutaneous drainage and the catheter was removed after one month. She is still alive after 22 months of follow up. She is asymptomatic, with mild diabetes and a normal exocrine pancreatic function. The last CT scan and tumor markers were negative. Conclusion Less than 30 cases of dermoid cyst of the pancreas have been reported in the English literature. Most of patients were symptomatic by unspecific gastrointestinal discomfort. Imaging techniques failed the correct preoperative diagnosis, because the appearance may vary depending on the proportions of tissue components. They should be considered in the differential diagnosis of slow-growing benign pancreatic cysts. Despite the benign nature of dermoid cyst, oncologic resection is usually performed due to difficult preoperative diagnosis. No reliable predictive features were found to allow an organ- or parenchyma-preserving procedure. Surgery remains the treatment of choice to exclude malignancy.

description: We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplectic reflection algebras and graded Hecke algebras to the quantum setting over a field of arbitrary characteristic. We give necessary and sufficient conditions for such algebras to satisfy a Poincare-Birkhoff-Witt property using the theory of noncommutative Groebner bases. We include applications to the case of abelian groups and the case of groups acting on coordinate rings of quantum planes. In addition, we classify graded automorphisms of the coordinate ring of quantum 3-space. In characteristic zero, Hochschild cohomology gives an elegant description of the Poincare-Birkhoff-Witt conditions.
