Volvulella fortis

description: Volvulella fortis (Thiele, 1925) Figs 81C, 82 Volvula fortis Thiele, 1925: 239, pl. 31, fig. 23. TYPE MATERIAL. — Probably lost (could not be located at ZMA). TYPE LOCALITY. — Nias south Channel, Indonesia, 0°30.2’N, 97°59.7’E, 132 m [Valdivia: stn 193]. MATERIAL EXAMINED. — New Caledonia proper. BATHUS 1: stn DW 654, Passe de Canala, 21°17’S, 165°57’E, 237-298 m, 2 dd (Fig. 81C); stn DW674, Grande Passe de Touho, 20°49’S, 165°19’E, 105-110 m, 1 dd. DISTRIBUTION. — Originally described from the south of Nias Island, off Sumatra, Indonesia, in 123 m (Thiele, 1925). The material herein represents the first record from New Caledonia (Fig. 82), in 110-237 m. DESCRIPTION. — Shell morphology. Length 2.5 mm, width 0.8 mm (largest specimen examined). Shell fragile, elongate, with nearly parallel sides (Fig. 81C). Only 1 whorl visible, forming the entire shell. Anterior end of the shell rounded. Umbilicus closed. Aperture long, wide anteriorly, narrowing gradually at about 1/3-1/2 of its length. At its apical end, the aperture bends over the apex of the shell and the parietal wall forms a short spine that completely covers the apex. Columellar margin slightly twisted anteriorly. Sculpture of 13 simple spiral grooves at the posterior end and 6 at the anterior end. Colour uniformly whitish. Anatomy. Unknown. All shells collected lacked soft parts. REMARKS. — Volvulella fortis was originally described as an elongate species with spiral grooves near the two ends of the shell. The material from New Caledonia examined here matches the original description. Volvulella ovulina has a much shorter and wider shell and the spiral grooves are only present near the anterior end of the shell. Two other similar species are Volvulella radiola (A. Adams, 1862) and Volvulella tokunagai (Makiyama, 1927), which also have an elongate shell, but they both have the entire surface of the shell covered with widely separated faint spiral grooves.

Through the border : Senegalese gendered migration to Spain (2005-2010)
Creators: name: Vives Gonzalez, Celia
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation provides a geopolitical and gender analysis of the border that was built between 2005 and 2010 to stop unwanted migration from Senegal to Spain. I combine an investigation of institutional practices and of the experiences of migrants who crossed (or tried to cross) that border. This work constructs a genealogy of the Spanish - Senegalese border, including the obstacles placed to stop unwanted migration and the strategies adopted by migrants to enter EU space. To do so I draw from three bodies of literature: scholarship on migrant transnationalism, critical geopolitics, and feminist political geography. This analysis is built on extensive primary research complemented by secondary data, including life histories, participant observation, and interviews with migrants, members of their transnational social networks, former smugglers, service providers, supra-state organizations, state bureaucrats, and state security forces, as well as official statistics, legislation, and media accounts. I contend that gender is an articulating factor of international migrations. In the case of contemporary Senegalese migration to Spain, I argue that the re-enforcement and militarization of the border was disproportional to the number of migrants using land and sea routes. These efforts were partly responsible for a decrease in illegal migration by land and sea after 2007, but migration by air and secondary migration from other countries of the EU (which represent the majority of the migrant flow) was unaffected. Despite the obstacles placed to stop it, the migration of Senegalese continued and even increased during this period, mainly thanks to the support that transnational social networks provided to migrants. The main consequence of the preventive and defensive anti-immigration measures adopted was a re-territorialization of the EU border. The findings suggest the importance of integrating a variety of scales in the study of the processes, actors, and mechanisms involved in the territorial re-definition of state and supranational borders. In the case of the EU, I contend that as a response militarization is ethically questionable, economically wasteful, and inadequate. Finally, this study suggests the need to engage in a mobile cartography of the migrant transnational network to account for its transformations across time and space.

description: “For me theater has been and still is my passion, the only passion of my life, alive, strong, burning like a fever, and even if it has cost me a lot of sacrifices and a lot of pain, it has procured for me many joys and satisfactions” (“Fabienne Fabrèges” 6). In these words, Fabienne Fabrèges explains the emotional energy that accompanied her throughout her career, which, at first, led her to tour the major theaters of Europe as a theatre actress, and then into performing in more than sixty motion pictures. Fabrèges is one of a generation of young “modern” women who, at the beginning of the twentieth century, were able to move beyond the fixed roles (legislative, cultural and symbolic) imposed upon them in Western society, to pursue their careers (Guerra 2008, 39-48), even if that meant sacrificing family life. In this interview she is remembering the tenacity that she had to maintain during her struggles in order to achieve her objectives, which is also why reviewers generally recognized her as a cultured, intelligent actress with a personal and accurate way of playing her roles.
The effects of baryonic cooling on the concentration-mass relation
Creators: name: Fedeli, C.

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: I re-examine the relation between virial mass and concentration for groups and clusters of galaxies as measured in a number of recent works. As previously noted by several authors, low-mass clusters and groups of galaxies display systematically larger concentrations than simple prescriptions based on pure $n$-body simulations would predict. This implies an observed concentration-mass relation with a substantially larger slope/normalization than expected from theoretical investigations. Additionally, this conclusion seems to be quite independent on selection effects, holding for both lensing based and X-ray based cluster samples. In order to shed new light on this issue I employ a simple spherical halo model containing, in addition to dark matter, also stars and hot diffuse gas in proportions and with distributions in agreement with the most recent observations. Moreover, I include the contraction effect experienced by dark matter due to the cooling of baryons in the very central part of the structure itself. The resulting modified concentration-mass relation is steeper than the theoretical input one, because star formation is fractionally more efficient in low-mass objects. However, the effect is non-vanishing at all masses, thus resulting also in a larger normalization. Overall the new relation provides a better representation of the observed one for almost all catalogs considered in this work, although the specific details depend quite significantly on the baryon fraction prescription adopted. Anyhow, the same effect could also be produced by a redistribution of baryons within the structure. Finally I use this simple model to show how the estimated concentration of cosmic structures is expected to be overestimated as a function of the radial range covered by the analysis. (abridged)

description: This paper presents a review of imaging techniques and of their utility in system biology. During the last decade systems biology has matured into a distinct field and imaging has been increasingly used to enable the interplay of experimental and theoretical biology. In this review, we describe and compare the roles of microscopy, ultrasound, CT (Computed Tomography), MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and molecular probes such as quantum dots and nanoshells in systems biology. As a unified application area among these different imaging techniques, examples in cancer targeting are highlighted.

At its apical end, the aperture bends over the apex of the shell and the parietal wall forms a short spine that completely covers the apex. Columellar margin slightly twisted. Sculpture of numerous, faint and densely concentrated spiral grooves crossed by fine growth lines all over its surface. Colour uniformly shiny whitish. Anatomy. Unknown. All shells collected lacked soft parts. REMARKS. — Volvulella multistriata is similar in shell morphology to Volvulella radiola (A. Adams, 1862) from Japan, redescribed by Hori (2000c). The main differences between them include the sculpture, which is composed of densely arranged faint spiral grooves in V. multistriata and widely spaced grooves in V. radiola. In addition, the apical spine of V. radiola is much longer and more curved than that of V. multistriata, and the apical region of V. multistriata narrows more gradually than in V. radiola. Another similar species is Volvulella tokunagai Makiyama, 1927, which differs from V. multistriata in having a more gradually narrowing apical region and the spiral grooves widely spaced (see Hori 2000c). ETYMOLOGY. — From the Latin for numerous striae, in reference to the sculpture of this species composed of densely arranged spiral grooves.

description: We show that the scattering interaction between a high energy electron and a photon can be strongly enhanced by different types of localized plasmons in a non-trivial way. The scattering interaction is predicted by an eigen-response theory, numerically verified by finite-difference-time-domain simulation, and experimentally verified by cathodoluminescence spectroscopy. We find that the scattering interaction associated with dark plasmons can be as strong as that of bright plasmons. Such a strong interaction may offer new opportunities to improve single-plasmon detection and high-resolution characterization techniques for high quality plasmonic materials.

description: Between 1904 and 1915, Marion Fairfax wrote several successful Broadway plays before turning to screenwriting. Over the next eleven years, she achieved even greater success in her new field. In 1921, she formed her own production company that produced The Lying Truth (1922), which Fairfax wrote and directed. The most enduring film with which she was associated was The Lost World (1925), a science fiction picture about an isolated land of dinosaurs that featured tremendous special effects. A handwritten note attached to a First National Pictures legal department memo dated December 6, 1923, states: “Fairfax is always a winner—Don’t ever let her get away. Tom [unidentified] knows she is both restless and damn independent.” Three years later, however, Fairfax received her final credit for The Blonde Saint (1926) and then disappeared from filmmaking. She was married to actor Tully Marshall, who died in 1943, for forty-three years.

description: We study the rate of decay of correlations for equilibrium states associated to a robust class of non-uniformly expanding maps where no Markov assumption is required. We show that the Ruelle-Perron-Frobenius operator acting on the space of Holder continuous observables has a spectral gap and deduce the exponential decay of correlations and the central limit theorem. In particular, we obtain an alternative proof for the existence and uniqueness of the equilibrium states and we prove that the topological pressure varies continuously. Finally, we use the spectral properties of the transfer operators in space of differentiable observables to obtain strong stability results under deterministic and random perturbations.

description: This study investigates the pollution status, spatial distribution of heavy metals including Cr, Mn, Ni, Cu, Zn, As, Cd and Pb, in sediments from the Longhu Lake, and evaluates possible ecological risk of these metals. Average concentrations of Cu, Zn, Cd and Pb were 2.1, 3.5, 8.0 and 2.5 times higher than Grade I Chinese soil quality standard respectively. The geo-accumulation index indicates that the lake sediments are moderate to heavily contaminated by Zn, Cd and Pb, which may have higher toxic effects than other metals. The potential ecological risk factor (Eir) suggests low risk to aquatic organisms except for Cd which has a considerable risk to aquatic biota. Spearman correlation and principal component analysis suggest that Mn, Zn, Cd and Pb possibly having similar anthropogenic sources and behaviors in the lake. Overall, this study suggests that anthropogenic inputs are from local point and non-point sources, runoff and atmospheric deposition.
Many faces of low mass neutralino dark matter in the unconstrained MSSM, LHC data and new signals

description: If all strongly interacting sparticles (the squarks and the gluinos) in an unconstrained minimal supersymmetric standard model (MSSM) are heavier than the corresponding mass lower limits in the minimal supergravity (mSUGRA) model, obtained by the current LHC experiments, then the existing data allow a variety of electroweak (EW) sectors with light sparticles yielding dark matter (DM) relic density allowed by the WMAP data. Some of the sparticles may lie just above the existing lower bounds from LEP and lead to many novel DM producing mechanisms not common in mSUGRA. This is illustrated by revisiting the above squark-gluino mass limits obtained by the ATLAS Collaboration, with an unconstrained EW sector with masses not correlated with the strong sector. Using their selection criteria and the corresponding cross section limits, we find at the generator level using Pythia, that the changes in the mass limits, if any, are by at most 10-12% in most scenarios. In some cases, however, the relaxation of the gluino mass limits are larger ($\approx 20%$). If a subset of the strongly interacting sparticles in an unconstrained MSSM are within the reach of the LHC, then signals sensitive to the EW sector may be obtained. This is illustrated by simulating the $blj$$\etslash$, $l= e and μ$, and $bτj$$\etslash$ signals in i) the light stop scenario and ii) the light stop-gluino scenario with various light EW sectors allowed by the WMAP data. Some of the more general models may be realized with non-universal scalar and gaugino masses.

description: The sisters Adriana and Dolores Ehlers, who worked together all their lives, were pioneers in every area of filmmaking. As Dolores described in a 1977 interview, they shot documentaries, worked in film processing laboratories, sold projection apparatuses, and participated in the politics surrounding cinema during the difficult phase of the Mexican Revolution known as carrancismo (Ehlers n.p.). When they were children, their father died and their mother supported them by working as a midwife. They lived with another family in the port city of Veracruz and politically supported the anti-Porfirian aims of the Revolution’s generals, Madero and Carranza, aligning themselves with other women leaders of the time (Ehlers n.p.).

description: In this paper we focus on analytical calculations involving null geodesics in some spherically symmetric spacetimes. We use Weierstrass elliptic functions to fully describe null geodesics in Schwarzschild spacetime and to derive analytical formulae connecting the values of radial distance at different points along the geodesic. We then study the properties of light triangles in Schwarzschild spacetime and give the expansion of the deflection angle to the second order in both $M/r_0$ and $M/b$ where $M$ is the mass of the black hole, $r_0$ the distance of closest approach of the light ray and $b$ the impact parameter. We also use the Weierstrass function formalism to analyze other more exotic cases such as Reissner-Nordstr\om null geodesics and Schwarzschild null geodesics in 4 and 6 spatial dimensions. Finally we apply Weierstrass functions to describe the null geodesics in the Ellis wormhole spacetime and give an analytic expansion of the deflection angle in $M/b$.

description: We explore the nature of the quantum phase transition between a magnetically ordered state with collinear spin pattern and a gapless $Z_2$ spin liquid in the Heisenberg-Kitaev model. We construct a slave particle mean field theory for the Heisenberg-Kitaev model in terms of complex fermionic spinons. It is shown that this theory, formulated in the appropriate basis, is capable of describing the Kitaev spin liquid as well as the transition between the gapless $Z_2$ spin liquid and the so-called stripy antiferromagnet. In particular, within a mean field theory, we have a discontinuous transition from the $Z_2$ spin liquid to the stripy antiferromagnet. We argue, however, that subtle spinon confinement effects, associated with the instability of gapped U(1) spin liquid in two spatial dimensions, are playing an important role at the transition. The possibility of an exotic continuous transition is briefly addressed.

description: During the 1910s and 1920s, Aud Egede-Nissen and her sisters Gerd and Ada made a name for themselves in the Nordic and German film industries as actors, producers, and directors. Like many female pioneers in the film industry, their work has been neglected. The contribution of the Egede-Nissen sisters, especially Aud, to silent film in the 1910s is remarkable given the odds they had to overcome as female producers in a male-dominated industry and the lack of tradition and experience in their home country, Norway.

description: This paper presents the implementation and quantitative evaluation of a multiphase three-dimensional deformable model in a level set framework for automated segmentation of brain MRIs. The segmentation algorithm performs an optimal partitioning of three-dimensional data based on homogeneity measures that naturally evolves to the extraction of different tissue types in the brain. Random seed initialization was used to minimize the sensitivity of the method to initial conditions while avoiding the need for a priori information. This random initialization ensures robustness of the method with respect to the initialization and the minimization set up. Postprocessing corrections with morphological operators were applied to refine the details of the global segmentation method. A clinical study was performed on a database of 10 adult brain MRI volumes to compare the level set segmentation to three other methods: "idealized" intensity thresholding, fuzzy connectedness, and an expectation maximization classification using hidden Markov random fields. Quantitative evaluation of segmentation accuracy was performed with comparison to manual segmentation computing true positive and false positive volume fractions. A statistical comparison of the segmentation methods was performed through a Wilcoxon analysis of these error rates and results showed very high quality and stability of the multiphase three-dimensional level set method.

description: Presentation given by Dr Samantha P. Kanza on behalf of PSDI at ACS Fall 2023. Abstract: The Electronic Lab Notebook (ELN) was originally created to serve as a direct replacement for the paper lab notebook, to ensure the digital capture and retention of the scientific record. What seemed like an obvious simple software-based solution has been anything but, and there are now over 80 active ELNs on the market and a wide range of different approaches have been taken to digitizing scientific research across academia and industry.
This talk will discuss the shift in software offerings and attitudes to process recording software and report on the results of a recent survey on ELN and Notebook Usage in our physical sciences community. We will also discuss the current work that is being undertaken to produce a comprehensive resource on process recording tools to aid researchers in identifying the best solution(s) for them.
It has become clear over the last two decades that the implementation and adoption of any process recording software in the research environment is a multifaceted socio-technical matter, with many potential barriers and considerations. However, there has been a noticeable shift over the last few years of the offerings of laboratory management software as a whole, and many companies now offer entire suites of software including Laboratory Information Management Systems (LIMS), Laboratory Execution Systems (LES), Scientific Data Management Software (SDMS), links to chemical registries, inventory management, and at the heart of all of these offerings remains an ELN, which is suddenly so much more than a paper lab notebook replacement. Additionally, there has been an increase in the offerings of the generic notebooking software with a much wider range of features, and in many cases the ability to create your own plugins for generic or domain specific needs.

description: By implementing a recent technique for the determination of stochastic eigendirections of two coupled stochastic variables, we investigate the evolution of fluctuations of NO2 concentrations at two monitoring stations in the city of Lisbon, Portugal. We analyze the stochastic part of the measurements recorded at the monitoring stations by means of a method where the two concentrations are considered as stochastic variables evolving according to a system of coupled stochastic differential equations. Analysis of their structure allows for transforming the set of measured variables to a set of derived variables, one of them with reduced stochasticity. For the specific case of NO2 concentration measures, the set of derived variables are well approximated by a global rotation of the original set of measured variables. We conclude that the stochastic sources at each station are independent from each other and typically have amplitudes of the order of the deterministic contributions. Such findings show significant limitations when predicting such quantities. Still, we briefly discuss how predictive power can be increased in general in the light of our methods.

description: Machine-to-Machine (M2M) communication is now playing a market-changing role in a wide range of business world. However, in event-driven M2M communications, a large number of devices activate within a short period of time, which in turn causes high radio congestions and severe access delay. To address this issue, we propose a Fast Adaptive S-ALOHA (FASA) scheme for M2M communication systems with bursty traffic. The statistics of consecutive idle and collision slots, rather than the observation in a single slot, are used in FASA to accelerate the tracking process of network status. Furthermore, the fast convergence property of FASA is guaranteed by using drift analysis. Simulation results demonstrate that the proposed FASA scheme achieves near-optimal performance in reducing access delay, which outperforms that of traditional additive schemes such as PB-ALOHA. Moreover, compared to multiplicative schemes, FASA shows its robustness even under heavy traffic load in addition to better delay performance.

description: Winnifred Eaton is best known for her success as a novelist under the pseudo-Japanese pen name Onoto Watanna, but she also worked as a screenwriter, title writer, literary advisor, and scenario editor for Universal and Metro-Goldwyn-Mayer between 1921 and 1930, and wrote a number of poignant articles on both the profession of the Hollywood screenwriter and the Asian-American experience. Eaton was born to a British father and a Chinese mother who left England for Hudson, New York, before settling in Montreal, where she was born. She supposedly wrote under a Japanese pseudonym to safeguard herself against fervent anti-Chinese sentiments of the time (Hicks et al. 2000, 201), expressed through legislation such as Chester A. Arthur’s 1882 Chinese Exclusion Act, which was not repealed until 1943. As Onoto Watanna, Eaton played into and strengthened the popular late-nineteenth century Japanese strand of orientalism known as japonisme, which permeated the arts, design, fashion, film, and literature, even though she would never visit Japan. She was progressive for her time, however, in that her romances were often characterized by interracial relationships. Her older sister, Edith Maude Eaton (1865-1914), tackled anti-Chinese sentiments head on, writing both journalism and fiction about the rough Chinese-American experience under the pen name of Sui Sin Far (Chen 2016, 185).

description: This paper presents a method of four-dimensional (4-D) (3-D+Time) space-frequency analysis for directional denoising and enhancement of real-time three-dimensional (RT3D) ultrasound and quantitative measures in diagnostic cardiac ultrasound. Expansion of echocardiographic volumes is performed with complex exponential wavelet-like basis functions called brushlets. These functions offer good localization in time and frequency and decompose a signal into distinct patterns of oriented harmonics, which are invariant to intensity and contrast range. Deformable-model segmentation is carried out on denoised data after thresholding of transform coefficients. This process attenuates speckle noise while preserving cardiac structure location. The superiority of 4-D over 3-D analysis for decorrelating additive white noise and multiplicative speckle noise on a 4-D phantom volume expanding in time is demonstrated. Quantitative validation, computed for contours and volumes, is performed on in vitro balloon phantoms. Clinical applications of this spatiotemporal analysis tool are reported for six patient cases providing measures of left ventricular volumes and ejection fraction.

description: We introduce a novel method of feature extraction for texture segmentation that relies on multichannel wavelet frames and 2-D envelope detection. We describe and compare two algorithms for envelope detection based on (1) the Hilbert transform and (2) zero crossings. We present criteria for filter selection and discuss quantitatively their effect on feature extraction. The performance of our method is demonstrated experimentally on samples of both natural and synthetic textures.

description: We review recent work on superlattices in monolayer and bilayer graphene. We highlight the role of the quasiparticle chirality in generating new Dirac fermion modes with tunable anisotropic velocities in one dimensional (1D) superlattices in both monolayer and bilayer graphene. We discuss the structure of the Landau levels and magnetotransport in such superlattices over a wide range of perpendicular (orbital) magnetic fields. In monolayer graphene, we show that an orbital magnetic field can reverse the anisotropy of the transport imposed by the superlattice potential, suggesting possible switching-type device applications. We also consider topological modes localized at a kink in an electric field applied perpendicular to bilayer graphene, and show how interactions convert these modes into a two-band Luttinger liquid with tunable Luttinger parameters. The band structures of electric field superlattices in bilayer graphene (with or without a magnetic field) are shown to arise naturally from a coupled array of such topological modes. We briefly review some bandstructure results for 2D superlattices. We conclude with a discussion of recent tunneling and transport experiments and point out open issues.

description: Lucy, Lady Duff-Gordon, professionally known as “Lucile,” was a couturière to wealthy European and American women as well as actresses in London, Paris, and New York when she began to design costumes for film stars. As early as 1913, she dressed Alice Joyce in Kalem’s The American Princess (1913). In addition, Lucile’s New York and London salons provided the setting for several motion pictures in which fashion show scenes were filmed. These included: The American Princess (Kalem, 1913), The Whirl of Life (Cort Film, 1915), The Spendthrift (George Kleine, 1915), The Amateur Wife (Famous Players-Lasky, 1920), and Walls of Prejudice (Gaumont, 1920).

description: We study the impact of recent direct and indirect searches for particle dark matter on supersymmetric models with resonant neutralino- or chargino-driven electroweak baryogenesis (EWB) and heavy sfermions. We outline regions of successful EWB on the planes defined by gaugino and higgsino mass parameters, and calculate the portions of those planes excluded by dark matter search results, and the regions soon to be probed by current and future experiments. We conclude that dark matter searches robustly exclude a wino-like lightest supersymmetric particle in successful EWB regions. Bino-like dark matter is still a possibility, although one that will be probed with a modest improvement in the sensitivity of current direct and indirect detection experiments. We also calculate the total production cross section of chargino and neutralino pairs at the Large Hadron Collider, with a center of mass energy of 7 and 14 TeV.

Tocopherol isoforms evoke specific modulation of oxidative and inflammatory responses in Caco-2 and FHs 74 Int intestinal cell lines
Creators: name: Elisia, Ingrid

description: Vitamin (vit) E comprises 8 isoforms, of which only α-tocopherol (Toc) has been thoroughly investigated. Other vit E isoforms, particularly γ-Toc and δ-Toc, however are present in significant amounts in the North American diet. The effect of α-Toc, γ-Toc and δ-Toc in modulating oxidative status and inflammatory responses in adult-derived Caco-2 and fetal-derived FHs 74 Int intestinal cell lines were thus determined. Toc isoforms were effective antioxidants that protected against peroxyl radical-induced membrane oxidation in both cell lines in an isoform-dependent manner (δ-Toc>γ-To>α-Toc). Nevertheless, Toc isoforms exhibited differential modulation of inflammatory response in the two cell lines, in that Toc isoforms suppressed IFNγ/PMA-induced IL8 expression in Caco-2 cells, but promoted an inflammatory response in FHs 74 Int cells. Modulation of IL8 expression by Toc isoforms corresponded with an efficacy of Toc to modulate NfκB pro-inflammatory and Nrf-2 antioxidant enzyme signaling pathways. Non-α-Toc isoforms promoted Nrf-2 activation in both cell lines. Alpha-Toc and γ-Toc mitigated IFNγ/PMA-induced NfκB activation in Caco-2 cells while non-α-Toc isoforms promoted NfκB activation in FHs 74 Int cells. The pro-oxidant activity of δ-Toc corresponded to its lower ability to suppress IFNγ/PMA-induced IL8 expression and NfκB activation, but enhanced the Nrf-2 signal in Caco-2 cells. One key difference between the effect of Toc isoforms on modulation of NfκB and Nrf-2 signaling was that non-α-Toc isoforms down-regulated the gene expression of glutamate cysteine ligase, the rate-limiting enzyme in glutathione biosynthesis, in FHs 74 Int, but not in Caco-2 cells. This was supported by a reduced (P<0.05) glutathione content in FHs 74 Int cells after incubation with γ-Toc and δ-Toc that was not observed in Caco-2 cells. Downregulation of the glutathione content corresponded to the finding that non-α-Toc isoforms can induce apoptosis-mediated cytotoxicity in FHs 74 Int, but not in Caco-2 cells. Taken together, Toc isoform-mediated modulation of the inflammatory response was not related to antioxidant activity, but rather was attributed to a cell-specific efficacy to modulate NfκB signaling that corresponded to depletion in glutathione content and apoptosis. Based on the current findings, non-α-Toc isoforms are biologically active forms of vit E and their effects on intestinal cells should not be overlooked.

description: Standard applications of the Bailey chain preserve mixed mock modularity but not mock modularity. After illustrating this with some examples, we show how to use a change of base in Bailey pairs due to Bressoud, Ismail and Stanton to explicitly construct families of q-hypergeometric multisums which are mock theta functions. We also prove identities involving some of these multisums and certain classical mock theta functions.
