description: Abstract Background Long-term lung allograft survival is limited by bronchiolitis obliterans syndrome (BOS). Mannose binding lectin (MBL) belongs to the innate immune system, participates in complement activation, and may predispose to graft rejection. We investigated mannose binding (MBL) during cold ischemia and in tissue samples from explanted lungs with BOS, and assessed MBL and complement proteins in plasma post-lung transplantation relative to BOS staging. Methods MBL was detected by immunohistochemistry lung tissue at the time of cold ischemia and in samples with BOS. MBL was assayed in the peripheral blood of 66 lung transplant patients transplanted between 1990–2007. Results MBL localized to vasculature and basement membrane during cold ischemia and BOS. Patients further out post-lung transplant > 5 years (n = 33), had significantly lower levels of MBL in the blood compared to lung transplant patients < 5 years with BOS Op-3 (n = 17), 1738 ± 250 ng/ml vs 3198 ± 370 ng/ml, p = 0.027, and similar levels to lung transplant patients < 5 years with BOS 0 (n = 16), 1738 ± 250 ng/ml vs 1808 ± 345 ng/ml. MBL levels in all BOS 0 (n = 30) vs. all BOS Op-3 (n = 36) were 1378 ± 275 ng/ml vs. 2578 ± 390 ng/ml, p = 0.001, respectively. C3 plasma levels in BOS 0 (n = 30) vs. BOS Op-3 (n = 36) were 101 ± 19.8 mg/ml vs. 114 ± 25.2 mg/ml, p = 0.024, respectively. Conclusions MBL localizes within the lung during graft ischemia and BOS, higher levels of plasma MBL are associated with BOS Op-3 and < 5 years post-transplant, and higher level of plasma complement protein C3 was associated with BOS Op-3 clinical status. MBL may serve as a biomarker for poorer outcome post-lung transplantation.
Feed-Forward-Only Training of Neural Networks

description: While artificial neural networks have reached immense advances over the last decade, the underlying approach to training neural networks, that is, solving the credit assignment problem by computing gradients with back-propagation, has remained largely the same. Nonetheless, back-propagation has long been criticized for being biologically implausible as it relies on concepts that are not viable in the brain. With delayed error forward projection (DEFP), I introduce a feed-forward-only training algorithm that solves two core issues for biological plausibility: the weight transport and the update locking problem. It is based on the similarly plausible direct random target projection algorithm but improves the approximated gradients by using delayed error information as a sample-wise scaling factor in place of the targets. By evaluating delayed error forward projection on image classification with fully-connected and convolutional neural networks, I find that it can achieve higher accuracy than direct random target projection, especially for fully- connected networks. Interestingly, scaling the updates with the error yields significantly better results than scaling with the gradient of the loss for all networks and datasets. In total, delayed error forward projection demonstrates the applicability of feed-forward-only training algorithms. This offers exciting new possibilities for both in-the-loop training on neuromorphic devices and pipelined parallelization.

description: Similar to Data Management Plans, Software Management Plans help formalize a set of structures and goals that ensure the software is accessible and reusable in the short, medium and long term. The ELIXIR SMP (DOI:10.37044/osf.io/k8znb) has been developed by the ELIXIR Software Development Best Practices Group in the ELIXIR Tools Platform to support researchers in life sciences. Although targeting the life sciences community, most of the elements of the ELIXIR SMPs are domain agnostic and could be used by other communities as well. DMPs and SMPs can be presented as text-based documents, sometimes guided by a set of questions corresponding to key points related to the lifecycle of either data or software. The FAIRification road for ELIXIR SMPs include two main components: turning them into machine-actionable SMPs (maSMPs) and aligning them to FAIR Digital Objects (FDOs). Our maSMP version will be based on the machine-actionable DMPs proposed by the Research Data Alliance DMP Common Standards Working Group, which corresponds to a structured representation of the most common elements present in a DMP (DOI:10.15497/rda00039) while the alignment with FDOs will be supported by Research Object Crates (RO-Crates). An RO-Crate (DOI:10.3233/DS-210053) is an open, community-driven, and lightweight approach based on schema.org annotations.

description: Abstract Background The catechol-O-methyltransferase (COMT) enzyme has been widely studied due to its multiple roles in neurological functioning, estrogen biology, and methylation metabolic pathways. Numerous studies have investigated variation in the large COMT gene, with the majority focusing on single nucleotide polymorphisms (SNPs). This body of work has linked COMT genetic variation with a vast array of conditions, including several neurobehavioral disorders, pain sensitivity, and multiple human cancers. Based on COMT’s numerous biological roles and recent studies suggesting that methylation of the COMT gene impacts COMT gene expression, we comprehensively interrogated methylation in over 200 CpG dinucleotide sequences spanning the length of the COMT gene. Methods Using saliva-derived DNA from a non-clinical sample of human subjects, we tested for associations between COMT CpG methylation and factors reported to interact with COMT genetic effects, including demographic factors and alcohol use. Finally, we tested associations between COMT CpG methylation state and COMT gene expression in breast cancer cell lines. We interrogated >200 CpGs in 13 amplicons spanning the 5’ UTR to the last exon of the CpG dinucleotide-rich COMT gene in n = 48 subjects, n = 11 cell lines and 1 endogenous 18S rRNA control. Results With the exception of the CpG island in the 5’UTR and 1st exon, all other CpG islands were strongly methylated with typical dynamic ranges between 50-90%. In the saliva samples, methylation of multiple COMT loci was associated with socioeconomic status or ethnicity. We found associations between methylation at numerous loci and genotype at the functional Val 158 Met SNP (rs4680), and most of the correlations between methylation and demographic and alcohol use factors were Val 158 Met allele-specific. Methylation at several of these loci also associated with COMT gene expression in breast cancer cell lines. Conclusions We report the first comprehensive interrogation of COMT methylation. We corroborate previous findings of variation in COMT methylation with gene expression and the Val 158 Met genotype, and also report novel associations with socioeconomic status (SES) and ethnicity at several methylated loci. These results point to novel mechanisms for COMT regulation, which may have broad therapeutic implications.

description: We consider $n^2\times n^2$ real symmetric and hermitian matrices $M_n$, which are equal to sum of $m_n$ tensor products of vectors $X^μ=B(Y^μ\otimes Y^μ)$, $μ=1,\dots,m_n$, where $Y^μ$ are i.i.d. random vectors from $\mathbb R^n (\mathbb C^n)$ with zero mean and unit variance of components, and $B$ is an $n^2\times n^2$ positive definite non-random matrix. We prove that if $m_n/n^2\to c\in [0,+\infty)$ and the Normalized Counting Measure of eigenvalues of $BJB$, where $J$ is defined below, converges weakly, then the Normalized Counting Measure of eigenvalues of $M_n$ converges weakly in probability to a non-random limit and its Stieltjes transform can be found from a certain functional equation.

description: We have performed {\it ab initio} calculations for a series of energetic solids to explore their structural and electronic properties. To evaluate the ground state volume of these molecular solids, different dispersion correction methods were accounted in DFT, namely the Tkatchenko-Scheffler method (with and without self-consistent screening), Grimme's methods (D2, D3(BJ)) and the vdW-DF method. Our results reveals that dispersion correction methods are essential in understanding these complex structures with van der Waals interactions and hydrogen bonding. The calculated ground state volumes and bulk moduli show that the performance of each method is not unique, and therefore a careful examination is mandatory for interpreting theoretical predictions. This work also emphasizes the importance of quasiparticle calculations in predicting the band gap, which is obtained here with the GW approximation. We find that the obtained band gaps are ranging from 4 to 7 eV for the different compounds, indicating their insulating nature. In addition, we show the essential role of quasiparticle band structure calculations to correlate the gap with the energetic properties.

description: Abstract Introduction Macrophages comprise an essential component of the mammary microenvironment necessary for normal gland development. However, there is no viable in vivo model to study their role in normal human breast function. We hypothesized that adding primary human macrophages to the murine mammary gland would enhance and provide a novel approach to examine immune-stromal cell interactions during the humanization process. Methods Primary human macrophages, in the presence or absence of ectopic estrogen stimulation, were used to humanize mouse mammary glands. Mechanisms of enhanced humanization were identified by cytokine/chemokine ELISAs, zymography, western analysis, invasion and proliferation assays; results were confirmed with immunohistological analysis. Results The combined treatment of macrophages and estrogen stimulation significantly enhanced the percentage of the total gland humanized and the engraftment/outgrowth success rate. Timecourse analysis revealed the disappearance of the human macrophages by two weeks post-injection, suggesting that the improved overall growth and invasiveness of the fibroblasts provided a larger stromal bed for epithelial cell proliferation and structure formation. Confirming their promotion of fibroblasts humanization, estrogen-stimulated macrophages significantly enhanced fibroblast proliferation and invasion in vitro, as well as significantly increased proliferating cell nuclear antigen (PCNA) positive cells in humanized glands. Cytokine/chemokine ELISAs, zymography and western analyses identified TNFα and MMP9 as potential mechanisms by which estrogen-stimulated macrophages enhanced humanization. Specific inhibitors to TNFα and MMP9 validated the effects of these molecules on fibroblast behavior in vitro, as well as by immunohistochemical analysis of humanized glands for human-specific MMP9 expression. Lastly, glands humanized with macrophages had enhanced engraftment and tumor growth compared to glands humanized with fibroblasts alone. Conclusions Herein, we demonstrate intricate immune and stromal cell paracrine interactions in a humanized in vivo model system. We confirmed our in vivo results with in vitro analyses, highlighting the value of this model to interchangeably substantiate in vitro and in vivo results. It is critical to understand the signaling networks that drive paracrine cell interactions, for tumor cells exploit these signaling mechanisms to support their growth and invasive properties. This report presents a dynamic in vivo model to study primary human immune/fibroblast/epithelial interactions and to advance our knowledge of the stromal-derived signals that promote tumorigenesis.
An integrated analysis of the SOX2 microRNA response program in human pluripotent and nullipotent stem cell lines

Publisher: name: BioMed Central Ltd
Year: 2014

description: Abstract Background SOX2 is a core component of the transcriptional network responsible for maintaining embryonal carcinoma cells (ECCs) in a pluripotent, undifferentiated state of self-renewal. As such, SOX2 is an oncogenic transcription factor and crucial cancer stem cell (CSC) biomarker in embryonal carcinoma and, as more recently found, in the stem-like cancer cell component of many other malignancies. SOX2 is furthermore a crucial factor in the maintenance of adult stem cell phenotypes and has additional roles in cell fate determination. The SOX2-linked microRNA (miRNA) transcriptome and regulome has not yet been fully defined in human pluripotent cells or CSCs. To improve our understanding of the SOX2-linked miRNA regulatory network as a contribution to the phenotype of these cell types, we used high-throughput differential miRNA and gene expression analysis combined with existing genome-wide SOX2 chromatin immunoprecipitation (ChIP) data to map the SOX2 miRNA transcriptome in two human embryonal carcinoma cell (hECC) lines. Results Whole-microRNAome and genome analysis of SOX2-silenced hECCs revealed many miRNAs regulated by SOX2, including several with highly characterised functions in both cancer and embryonic stem cell (ESC) biology. We subsequently performed genome-wide differential expression analysis and applied a Monte Carlo simulation algorithm and target prediction to identify a SOX2-linked miRNA regulome, which was strongly enriched with epithelial-to-mesenchymal transition (EMT) markers. Additionally, several deregulated miRNAs important to EMT processes had SOX2 binding sites in their promoter regions. Conclusion In ESC-like CSCs, SOX2 regulates a large miRNA network that regulates and interlinks the expression of crucial genes involved in EMT.

description: In the United States, the “collateral consequences” of a criminal record extend far beyond the period of physical detention. These disadvantages fall disproportionately on the shoulders of people of color, and on Black Americans in particular. Among the numerous policy mechanisms aimed at alleviating these collateral consequences, expungement – the extraction and isolation of official criminal records from public access – stands out as particularly promising in that it promises to provide criminalized individuals a “clean slate.” However, the emerging literature on the uptake rate of expungement policies in their current, petition-based state has been far from encouraging. This paper provides a critical race perspective to this emerging literature through a comparative analysis of expungement policies in New Jersey and Alabama. This analysis reveals that existing expungement policies are not simply ineffective; they are also active contributors to the racial disparities in the impacts mass incarceration. This paper concludes by suggesting that the only equitable path forward for expungement is to follow the lead of New Jersey and other states by providing expungement automatically to those who qualify.

description: In the legal imagination, Frederick Douglass is often viewed as a “constitutional utopian” for his efforts to salvage the prewar Constitution with an antislavery construction. Rejecting the views of both the Taney Court and the followers of William Lloyd Garrison, who saw the Constitution as “a covenant with death, and an agreement with hell,” Douglass and other political abolitionists put forward a redemptive view of the Constitution rooted in both the letter and the spirit of the document. For Douglass, the fierce contest over constitutional meaning suggested the amenability of the Constitution’s “plain meaning” to abolition and the importance of wresting political power, and thus interpretive power, from pro–slavery forces. The long–term potency of Douglass’s adaptive, literalist, and purposive method suggests the importance of his constitutional interpretation for formulating a racial justice jurisprudence today. The textualism practiced by the current Supreme Court, however, poses multiple challenges to the pursuit of that same goal. The questions that occupied Douglass’s day—whether and how to embrace a document tied to foundational injustice—have come to swirl not only around Douglass’s legacy but also around contemporary questions of constitutional theory, particularly pertaining to the relation of the text and textual interpretation to racial justice. In this paper, I will argue that Douglass’s textualism offers progressive constitutionalists a theory of interpretation that meets originalism on many of its own terms but also insists on a radically revised conception of constitutional meaning, one that centers racial justice first and foremost.

description: The use of carbonate-based paleoclimate archives has gained increasing importance to obtain reliable and detailed information on past climate and environmental variability in order to better understand the modern climate regime and the influence of anthropogenically induced global warming. In the last decades, the diversity of geochemical proxies available in carbonate palaeoclimate archives have emerged rapidly and significantly. Trace elements and traditional stable isotopes of oxygen and carbon have been supplemented with numerous non-traditional stable isotope systems such as B, Li, Ba, Mg, Ca, Sr, U, N, Δ17O, Δ47.In addition, the study of organic matter in carbonaceous archives and investigation of different biomarkers has massively expanded over the last years. Most importantly, recent developments in analytical techniques allow for improved precision, unprecedented resolution or smallest sample amounts. Furthermore, sophisticated isotope enabled diffusion-reaction models as well as high resolution experimental approaches significantly improved our understanding of the underlying fractionation processes. All these novel geochemical proxies and innovative methods open new advances towards qualitative and quantitative reconstruction in terrestrial and marine palaeoclimate studies and allow for multi-proxy approaches at different spatial and temporal scales. This session aims to bring together researchers from different fields of palaeoclimate research to share their knowledge, and allow inter-disciplinary exchange in order to apply these proxies to other palaeoclimate archives. We especially invite early career researcher to submit their abstracts to this interdisciplinary session. This will inspire both young researcher as well as senior scientists to apply new multi-proxy research approaches to study past climate variability.

description: Of the many jobs categorized as “essential” during the first wave of the COVID-19 pandemic, the continued operation of American meatpacking plants stood out. This work was 1) unrelated to critical healthcare services, 2) primarily staffed by minority and immigrant workers, and 3) conducted in conditions that seemed ideal for the coronavirus’ spread. Why and how did meatpacking facilities then remain open through the spring and summer of 2020, despite the proliferation of facility-linked COVID-19 hotspots and worker deaths? Drawing from authors of legal theory on racial capitalism, self-regulatory behavior by transnational corporations, and “precarity capitalism,” this paper builds context for this phenomenon through a case study on JBS USA Beef in Greeley, Colorado, the flagship facility for the American branch of world-leading meat producer JBS S.A. based in Brazil. It frames the protracted battle over production and worker safety as a standoff between workers of minority racial status, in precarious economic and labor conditions, and a winning coalition of powerful political and corporate stakeholders invested in the global value chain in beef.

description: For the Jordan algebra of hermitian matrices of order $n\ge 2$, we let $X$ be its submanifold consisting of rank-one semi-positive definite elements. The composition of the cotangent bundle map $π_X$: $T^*X\to X$ with the canonical map $X\to \mathbb{C}P^{n-1}$ (i.e., the map that sends a hermitian matrix to its column space), pulls back the Kähler form of the Fubini-Study metric on $\mathbb{C}P^{n-1}$ to a real closed differential two-form $ω_K$ on $T^*X$. Let $ω_X$ be the canonical symplectic form on $T^*X$ and $μ$ be a real number. A standard fact says that $ω_μ:=ω_X+2μ\,ω_K$ turns $T^*X$ into a symplectic manifold, hence a Poisson manifold with Poisson bracket $\{\, ,\,\}_μ$. In this article we exhibit a Poisson realization of the simple real Lie algebra $\mathfrak {su}(n, n)$ on the Poisson manifold $(T^*X, \{\, ,\,\}_μ)$, i.e., a Lie algebra homomorphism from $\mathfrak {su}(n, n)$ to $\left(C^\infty(T^*X, \mathbb R), \{\, ,\,\}_μ\right)$. Consequently one obtains the Laplace-Runge-Lenz vector for the classical $\mathrm{U}(1)$-Kepler problem with level $n$ and magnetic charge $μ$. Since the McIntosh-Cisneros-Zwanziger-Kepler problems (MICZ-Kepler Problems) are the $\mathrm{U}(1)$-Kepler problems with level $2$, the work presented here is a direct generalization of the work by A. Barut and G. Bornzin [ J. Math. Phys. $\bf 12$ (1971), 841-843] on the classical dynamic symmetry for the MICZ-Kepler problems.

description: The relations between most observables associated with a compact star, such as the mass and radius of a neutron star or a quark star, typically depend strongly on their unknown internal structure. The I-Love-Q relations (between the moment of inertia, the tidal deformability and the quadrupole moment) are however approximately insensitive to this structure. These relations become exact for stationary black holes in General Relativity as shown by the no-hair theorems. In this paper, we take the first steps toward studying how the approximate I-Love-Q relations become exact in the limit as compact stars become black holes. To do so, we consider a toy model, i.e. incompressible stars with anisotropic pressure, which allows us to model an equilibrium sequence of stars with their compactness approaching the black hole limit arbitrarily closely. We extract the I-Love-Q trio by numerically constructing such a sequence in the slow-rotation and small-tide approximations. We find that the I-Love-Q relations approach the black hole limit in a nontrivial way, with the quadrupole moment and the tidal deformability changing sign as the compactness and the amount of anisotropy are increased. Generalizing Maclaurin spheroids to anisotropic stars, we show that the multipole moments also change sign in the Newtonian limit as the amount of anisotropy is increased. We also prove analytically that the stellar moment of inertia reaches the black hole limit as the compactness reaches the black hole value in the strongly anisotropic limit. Modeling the black hole limit through a sequence of anisotropic stars, however, fails when considering other theories of gravity. We calculate the scalar dipole charge and the moment of inertia in a parity-violating modified theory and find that these quantities do not tend to their black hole counterparts as the anisotropic stellar sequence approaches the black hole limit.

description: Abstract Background Multiple genome-wide association studies (GWAS) within European populations have implicated common genetic variants associated with insulin and glucose concentrations. In contrast, few studies have been conducted within minority groups, which carry the highest burden of impaired glucose homeostasis and type 2 diabetes in the U.S. Methods As part of the 'Population Architecture using Genomics and Epidemiology (PAGE) Consortium, we investigated the association of up to 10 GWAS-identified single nucleotide polymorphisms (SNPs) in 8 genetic regions with glucose or insulin concentrations in up to 36,579 non-diabetic subjects including 23,323 European Americans (EA) and 7,526 African Americans (AA), 3,140 Hispanics, 1,779 American Indians (AI), and 811 Asians. We estimated the association between each SNP and fasting glucose or log-transformed fasting insulin, followed by meta-analysis to combine results across PAGE sites. Results Overall, our results show that 9/9 GWAS SNPs are associated with glucose in EA (p = 0.04 to 9 × 10-15), versus 3/9 in AA (p= 0.03 to 6 × 10-5), 3/4 SNPs in Hispanics, 2/4 SNPs in AI, and 1/2 SNPs in Asians. For insulin we observed a significant association with rs780094/GCKR in EA, Hispanics and AI only. Conclusions Generalization of results across multiple racial/ethnic groups helps confirm the relevance of some of these loci for glucose and insulin metabolism. Lack of association in non-EA groups may be due to insufficient power, or to unique patterns of linkage disequilibrium.

description: Future machine to machine (M2M) communications need to support a massive number of devices communicating with each other with little or no human intervention. Random access techniques were originally proposed to enable M2M multiple access, but suffer from severe congestion and access delay in an M2M system with a large number of devices. In this paper, we propose a novel multiple access scheme for M2M communications based on the capacity-approaching analog fountain code to efficiently minimize the access delay and satisfy the delay requirement for each device. This is achieved by allowing M2M devices to transmit at the same time on the same channel in an optimal probabilistic manner based on their individual delay requirements. Simulation results show that the proposed scheme achieves a near optimal rate performance and at the same time guarantees the delay requirements of the devices. We further propose a simple random access strategy and characterized the required overhead. Simulation results show the proposed approach significantly outperforms the existing random access schemes currently used in long term evolution advanced (LTE-A) standard in terms of the access delay.

description: This preregistered study is designed to replicate and extend the item-order effect described in Deaton (2012), where asking questions about political opinions resulted in reduced levels of well-being, as reported in the Cantril Ladder measure. This study tests whether this effect is due simply to making the political content salient or whether it results from the broader context of the questionnaire, which could change respondents' interpretation of the meaning of the Ladder question.

Clinical prediction models for bronchopulmonary dysplasia: a systematic review and external validation study
Creators: name: Laughon, Matthew
Publisher: name: BioMed Central Ltd
Year: 2013

description: Abstract Background Bronchopulmonary dysplasia (BPD) is a common complication of preterm birth. Very different models using clinical parameters at an early postnatal age to predict BPD have been developed with little extensive quantitative validation. The objective of this study is to review and validate clinical prediction models for BPD. Methods We searched the main electronic databases and abstracts from annual meetings. The STROBE instrument was used to assess the methodological quality. External validation of the retrieved models was performed using an individual patient dataset of 3229 patients at risk for BPD. Receiver operating characteristic curves were used to assess discrimination for each model by calculating the area under the curve (AUC). Calibration was assessed for the best discriminating models by visually comparing predicted and observed BPD probabilities. Results We identified 26 clinical prediction models for BPD. Although the STROBE instrument judged the quality from moderate to excellent, only four models utilised external validation and none presented calibration of the predictive value. For 19 prediction models with variables matched to our dataset, the AUCs ranged from 0.50 to 0.76 for the outcome BPD. Only two of the five best discriminating models showed good calibration. Conclusions External validation demonstrates that, except for two promising models, most existing clinical prediction models are poor to moderate predictors for BPD. To improve the predictive accuracy and identify preterm infants for future intervention studies aiming to reduce the risk of BPD, additional variables are required. Subsequently, that model should be externally validated using a proper impact analysis before its clinical implementation.

description: We analyze a model of itinerant electrons interacting through a quadrupole density-density repulsion in three dimensions. At the mean field level, the interaction drives a continuous Pomeranchuk instability towards $d$-wave, spin-triplet nematic order, which simultaneously breaks the SU(2) spin-rotation and spatial rotational symmetries. This order results in spin antisymmetric, elliptical deformations of the Fermi surfaces of up and down spins. We show that the effects of quantum fluctuations are similar to those in metallic ferromagnets, rendering the nematic transition first-order at low temperatures. Using the fermionic quantum order-by-disorder approach to self-consistently calculate fluctuations around possible modulated states, we show that the first-order transition is pre-empted by the formation of a nematic state that is intertwined with a helical modulation in spin space. Such a state is closely related to $d$-wave bond density wave order in square-lattice systems. Moreover, we show that it may coexist with a modulated, $p$-wave superconducting state.
