A mouse bleeding model to study oral anticoagulants
Creators: name: Monroe, Dougald M.
name: Hoffman, Maureane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: New oral anticoagulants to reduce the incidence of thrombosis have recently become available. When compared to the existing therapy, warfarin, these novel agents have similar efficacy with a reduced risk of spontaneous bleeding. However, these novel agents have been associated with significant, even fatal, bleeding following trauma. Reversal agents are being developed that bind and neutralize these oral anticoagulants. However, these are not yet available. Another strategy is to increase thrombin generation by administration of “bypassing” agents such as prothrombin complex concentrates or factor VIIa. Several animal models have been used to model the hemostatic defect induced by the thrombin inhibitor dabigatran. A rat tail injury model, a rabbit cuticle bleeding model, and a rabbit kidney laceration model have all been reported to show increased bleeding, but with supratherapeutic doses of dabigatran. A mouse tail transection model has been reported to reflect increased bleeding at peak therapeutic dabigatran levels. We found that the Whinna saphenous vein hemostasis model reliably reflects a hemostatic defect at therapeutic levels of dabigatran. This model can potentially reflect the effects of reversal or bypassing agents.

description: We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this design we demonstrate an atomic lithium source suitable for trapped-atom experiments. At a nozzle temperature of 525$^{\circ}$C the collimated atomic beam flux directly after the nozzle is $1.2 \times 10^{14}$ atoms per second with a peak beam intensity greater than $5.0 \times 10^{16}$ atoms per second per steradian. This suggests an oven lifetime of several decades of continuous operation.

description: Ovtsharenkoia gen. n. urn:lsid:zoobank.org:act: 22EE9CC4-BCC0-4E96-B57C-C84E920297E7 Type species. Hersiliola pallida Kroneberg, 1875. Etymology. The genus name is a patronym honoring our friend and colleague, and a prominent araneologist, Vladimir Ovtsharenko of New York, USA. Gender: feminine. Diagnosis. Ovtsharenkoia gen. n. can be easily distinguished from other genera of Hersiliidae by its short spinnerets and the shape of the copulatory organs. The male palp has a unique conformation for the family due to the presence of a complex outgrowth in the basal part of the tegulum. All other genera similar to Hersiliola have only one apophysis (tegular). Females of Ovtsharenkoia gen. n. can be recognized by a small median plate of the epigyne, a transverse translucent fertilization duct, large pale areas next to the median plate, and absence of distinct spermathecae. Description. Same as for the type species. Comments. A discoidal tegulum and whip-like embolus in O. pallida indicate that Ovtsharenkoia gen. n. is more closely related to Hersiliola than to two other Central Asian genera, Deltshevia gen. n. and Duninia gen. n., both of which have a globular tegulum and a thick, short embolus. A discoidal tegulum and whip-like embolus are also found in Hersilia. Embolus base modified, and differs from that in all other hersiliid genera. The epigyne of O. pallida has some similarity with those in Duninia gen. n. due to its pockets, but has an entirely different vulva. The type of embolus in O. pallida is similar to those in some Neotama species (cf. figs 45c, 46c in Baehr and Baehr 1993). Composition and distribution. Type species only, Ovtsharenkoia pallida (Kroneberg, 1875), found widely across the mountains and foothills from southern Turkmenistan to Uzbekistan, Kazakhstan, Kyrgyzstan, and Tajikistan; south to northern Pakistan.

description: Platelets play an important role in many physiological and pathological situations. However, the molecular mechanisms by which platelets contribute to health and disease are often ill-defined. One of the limiting factors to these studies is a fast but reliable method to generate animals with platelet-specific signaling defects. We here review recent approaches to establish an adoptive platelet transfer model in mice.

This is in sharp contrast to dimension-reduction phenomenon in (i) simple inductive limits of such algebras, where classification implies low-dimensional approximations, and (ii) when dimension is measured using decomposition rank, as the author and Winter proved that dr(C(X,U)) $\leq$ 2.

description: Since topological insulators were theoretically predicted and experimentally observed in semiconductors with strong spin-orbit coupling, more and more attention has been drawn to topological materials which host exotic surface states. These surface excitations are stable against perturbations since they are protected by global or spatial/lattice symmetries. Succeeded in achieving various topological insulators, a tempting challenge now is to search for metallic materials with novel topological properties. Here we predict that orthorhombic perovskite iridates realize a new class of metals dubbed topological crystalline metals, which support zero-energy surface states protected by certain lattice symmetry. These surface states can be probed by photoemission and tunnelling experiments. Furthermore, we show that by applying magnetic fields, the topological crystalline metal can be driven into other topological metallic phases, with different topological properties and surface states.

Calabi-Yau threefolds with large h^{2, 1}

description: We carry out a systematic analysis of Calabi-Yau threefolds that are elliptically fibered with section ("EFS") and have a large Hodge number h^{2, 1}. EFS Calabi-Yau threefolds live in a single connected space, with regions of moduli space associated with different topologies connected through transitions that can be understood in terms of singular Weierstrass models. We determine the complete set of such threefolds that have h^{2, 1} >= 350 by tuning coefficients in Weierstrass models over Hirzebruch surfaces. The resulting set of Hodge numbers includes those of all known Calabi-Yau threefolds with h^{2, 1} >= 350, as well as three apparently new Calabi-Yau threefolds. We speculate that there are no other Calabi-Yau threefolds (elliptically fibered or not) with Hodge numbers that exceed this bound. We summarize the theoretical and practical obstacles to a complete enumeration of all possible EFS Calabi-Yau threefolds and fourfolds, including those with small Hodge numbers, using this approach.

description: We report the formation of ultracold $^{7}$Li$^{85}$Rb molecules in the $a^{3}Σ^{+}$ electronic state by photoassociation (PA) and their detection via resonantly enhanced multiphoton ionization (REMPI). With our dual-species Li and Rb magneto-optical trap (MOT) apparatus, we detect PA resonances with binding energies up to ~62 cm$^{-1}$ below the $^{7}$Li 2s $^{2}S_{1/2}$ $+$ $^{85}$Rb 5p $^{2}P_{1/2}$ asymptote. In addition, we use REMPI spectroscopy to probe the $a^{3}Σ^{+}$ state and excited electronic $3^{3} Π$ and $4^{3} Σ^{+}$ states, and identify $a^{3}Σ^{+} (v" = 7 - 13)$, $3^{3} Π(v'_Π = 0 - 10)$ and $4^{3} Σ^{+} (v'_Σ = 0 - 5)$ vibrational levels. Our line assignments agree well with ab initio calculations. These preliminary spectroscopic studies on previously unobserved electronic states are crucial to discovering transition pathways for transferring ultracold LiRb molecules created via PA to deeply bound rovibrational levels of the electronic ground state.

description: Deep vein thrombosis and pulmonary embolism, collectively termed venous thromboembolism (VTE), affect over 1 million Americans each year. VTE is triggered by inflammation and blood stasis leading to the formation of thrombi rich in fibrin and red blood cells (RBCs). However, little is known about mechanisms regulating fibrin and RBC incorporation into venous thrombi, or how these components mediate thrombus size or resolution. Both elevated circulating fibrinogen (hyperfibrinogenemia) and abnormal fibrin(ogen) structure and function, including increased fibrin network density and resistance to fibrinolysis, have been observed in plasmas from patients with VTE. Abnormalities in RBC number and/or function have also been associated with VTE risk. RBC contributions to VTE are thought to stem from their effects on blood viscosity and margination of platelets to the vessel wall. More recent studies suggest RBCs also express phosphatidylserine, support thrombin generation, and decrease fibrinolysis. RBC interactions with fibrin(ogen) and cells, including platelets and endothelial cells, may also promote thrombus formation. The contributions of fibrin(ogen) and RBCs to the pathophysiology of VTE warrants further investigation.

description: Antiphospholipid syndrome (APS) is defined by the association of autoantibodies to certain phospholipid-binding proteins with arterial or venous thrombosis (‘AT’ or ‘VT’, respectively), and/or pregnancy-related morbidity (PM). Antiphospholipid antibodies (aPLA) promote activation of several cell types including monocytes, resulting in procoagulant tissue factor (TF) expression that may contribute to the vascular complications. Since TF synthesis by monocytes is frequently accompanied by release of TF-bearing microparticles, we hypothesized that plasma microparticle TF activity (MP-TF) may be elevated in APS patients and contribute to thrombosis and/or PM. Platelet-poor plasma specimens were obtained from 30 patients with definite APS and 72 patients with asymptomatic aPLA from the Antiphospholipid Syndrome Collaborative Registry (APSCORE). MP-TF was measured by an in-house factor Xa generation assay. The two groups were well matched for gender, age, ethnicity, proportions with underlying SLE, and aPLA profiles. MP-TF (median and (IQR)) in asymptomatic aPLA subjects was 0.09 pg/mL (0.05–0.14) compared to 0.13 pg/mL (0.10–0.17) in APS (p<0.001). No differences in MP-TF levels were observed between APS subjects with PM, thrombosis, or PM + thrombosis. Similarly, among subjects with either APS or asymptomatic aPLA, MP-TF did not differ in the presence or absence of underlying SLE. Prospective studies will be required to determine if plasma MP-TF activity is causally related to thrombotic or gestational complications in APS.

description: Karlin and McGregor's d-variable Hahn polynomials are shown to arise in the (d+1)-dimensional singular oscillator model as the overlap coefficients between bases associated to the separation of variables in Cartesian and hyperspherical coordinates. These polynomials in d discrete variables depend on d+1 real parameters and are orthogonal with respect to the multidimensional hypergeometric distribution. The focus is put on the d=2 case for which the connection with the three-dimensional singular oscillator is used to derive the main properties of the polynomials: forward/backward shift operators, orthogonality relation, generating function, recurrence relations, bispectrality (difference equations) and explicit expression in terms of the univariate Hahn polynomials. The extension of these results to an arbitrary number of variables is presented at the end of the paper.

subject: FOS: Physical sciences

description: We consider cosmological scenarios in which density perturbations are generated by the quantum fluctuations of the inflaton field at early times; the late time dynamics involves a modulus which first dominates the energy density of the universe and then decays to reheat the visible sector. By examining the evolution of energy density of the universe from the time of horizon exit of a pivot mode to the present day, and the fact that a modulus field decays via Planck suppressed interactions, we arrive at a relation which relates the mass of the modulus, inflationary observables/parameters and broad characteristics of the post inflationary reheating phase. When viewed together with generic expectations regarding reheating and the initial field displacement of the modulus after inflation, the relation gives a bound on the minimum mass of the modulus. For a large class of models, the bounds obtained (for the central values of Planck data) can be much stronger than the 'cosmological moduli problem' bound.

Red blood cells and thrombin generation in sickle cell disease

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The prothrombotic nature of sickle cell disease (SCD) is evidenced by the chronically elevated levels of almost all coagulation activation biomarkers, and an increased incidence of certain thrombotic events, including venous thromboembolism. Numerous studies have attempted to define the extent and elucidate the mechanism of the observed increase in thrombin generation in SCD patients in vivo. In general, these studies were performed using thrombin generation assays in platelet poor or platelet rich plasma and showed little difference in endogenous thrombin potential between the SCD cohort and healthy matched controls. In SCD, erythrocytes and monocytes have been demonstrated to exhibit procoagulant characteristics. Thus, the absence of these cellular components in standard thrombin generation assays may fail to reflect global hypercoagulability in the whole blood of patients with SCD. We were therefore surprised to see no difference in net thrombin generation in tissue factor-initiated initiated clotting of whole blood from patients with SCD. However, we are continuing to reconcile these seemingly disparate observations by slight modifications of the whole blood model that include alternative coagulation triggers and a re-examination of the net thrombin generation when the protein/protein S system is simultaneously interrogated.

description: The COVID-19 has changed consumer consumption patterns. This study aims to analyze the degree of exogenous effects of the pandemic on consumers' organic food consumption patterns. It uses the Consumer Behavior Survey for Food and explores whether the COVID-19 has impacted relative price premium for organic products. Our analysis shows that the pandemic has increased the willingness to pay for organic products from 1.3%p to 2.1%p. Households with higher incomes are willing to pay for organic products after the pandemic outbreak. While families with higher health interest have significantly increased the premium for organic products, those with relatively less health interest have reduced the price premium.

description: The sub-volume scaling of the entanglement entropy with the system's size, $n$, has been a subject of vigorous study in the last decade [1]. The area law provably holds for gapped one dimensional systems [2] and it was believed to be violated by at most a factor of $\log\left(n\right)$ in physically reasonable models such as critical systems. In this paper, we generalize the spin$-1$ model of Bravyi et al [3] to all integer spin-$s$ chains, whereby we introduce a class of exactly solvable models that are physical and exhibit signatures of criticality, yet violate the area law by a power law. The proposed Hamiltonian is local and translationally invariant in the bulk. We prove that it is frustration free and has a unique ground state. Moreover, we prove that the energy gap scales as $n^{-c}$, where using the theory of Brownian excursions, we prove $c\ge2$. This rules out the possibility of these models being described by a conformal field theory. We analytically show that the Schmidt rank grows exponentially with $n$ and that the half-chain entanglement entropy to the leading order scales as $\sqrt{n}$ (Eq. 16). Geometrically, the ground state is seen as a uniform superposition of all $s-$colored Motzkin walks. Lastly, we introduce an external field which allows us to remove the boundary terms yet retain the desired properties of the model. Our techniques for obtaining the asymptotic form of the entanglement entropy, the gap upper bound and the self-contained expositions of the combinatorial techniques, more akin to lattice paths, may be of independent interest.

description: Viral myocarditis is estimated to cause ∼20% of sudden death in people under the age of 40. A variety of viruses have been found to cause myocarditis including coxsackievirus B3 (CVB3). Many studies have been performed with CVB3 because there is a mouse model of CVB3-induced myocarditis. Studies have shown that the TLR3-IFNβ pathway plays a central role in the innate immune response to CVB3 infection. Our laboratory studies the role of protease activated receptors (PAR) in different biological responses including viral infection. We examined the effect of a deficiency in either PAR1 or PAR2 on CVB3-induced myocarditis. Interestingly, we found that PAR1 knockout mice had increased cardiac injury whereas PAR-2 knockout mice had decreased cardiac injury. Our studies support the notion that PARs modulate the innate immune response and can have both positive and negative effects on TLR-dependent responses.

Nelson Memo

description: During August 2022 the White House Office of Science and Technology Policy (OSTP) released a memo (generally known as the Nelson Memo) describing guidelines for “ensuring free, immediate, and equitable access to federally funded research”. The memo included guidelines for metadata which stated that federal agencies should: “Collect and make publicly available appropriate metadata15 associated with scholarly publications and data resulting from federally funded research, to the extent possible at the time of deposit in a public access repository. Such metadata should include at minimum: i) all author and co-author names, affiliations, and sources of funding, referencing digital persistent identifiers,16 as appropriate; ii) the date of publication; and, iii) a unique digital persistent identifier for the research output;” Existing metadata in many repositories were created and curated before these identifiers existed and, therefore, do not include these identifiers. To comply with the Nelson memo guidelines, these identifiers must be found, if possible, and added to the metadata. In other words, the metadata must be curated again, or re-curated, to include this new content and made publicly available. Metadata Game Changers has been exploring re-curation capabilities with many repositories for several years, developing and implementing tools and processes to find identifiers of many kinds, improving metadata, and sharing the improved metadata in the global research infrastructure. A recent talk describes three examples of this work with Dryad, a generalist repository, various institutional repositories, and a biological field station.

description: Fondaparinux is an antithrombin-dependent factor Xa inhibitor that is used for thromboprophylaxis of patients undergoing hip fracture surgery, hip or knee replacement, or abdominal surgery. It is cleared by the kidney and should be used with caution in patients with renal impairment and avoided in patients with severe renal insufficiency. Recently, several studies have demonstrated that a lower dose of fondaparinux in patients with moderate renal impairment appears to be safe and effective. The purpose of this study was to obtain pharmacokinetic and clinical data on the use of prophylactic fondaparinux inpatients with renal insufficiency undergoing major abdominal surgery for cancer (n=8) or orthopedic surgery (n=1). Anti-factor Xa levels were obtained, and a published population pharmacokinetic model for fondaparinux was fit to the data. The data were analyzed using NONMEM software. Fondaparinux did not appear to accumulate in these patients, even when the drug was administered for up to twelve days. Pharmacokinetic analysis revealed thatthe apparent clearance in this population, who were primarily undergoing cancer surgery, was similar to prior studies in orthopedic surgery patients. In contrast, lower estimates were obtained for volume of distribution and absorption rate constant parameters.None of the patients sustained a hemorrhagic complication attributable to fondaparinux. One patient developed hypoxia in the setting of transient atrial fibrillation and clinical suspicion for pulmonary embolism, but this was not confirmed radiographically. These results support the use of 1.5 mg of fondaparinux every 24 hours for thromboprophylaxis in patients with renal insufficiency undergoing high-risk surgical procedures.

description: Background: Thyroid cancer incidence is increasing, potentially due to enhanced diagnostic practices. However, access to healthcare may be dependent on socioeconomic status (SES) and race/ethnicity. Consequently, certain segments of the population may experience thyroid cancer overdiagnosis as a result of greater access to and use of enhanced diagnostic technology. The current study examined trends by SES in thyroid cancer incidence at the census tract level from 1995 to 2008 for the population of Texas, as well as by racial/ethnic subgroup.

description: Context: In astronomy, new approaches to process and analyze the exponentially increasing amount of data are inevitable. While classical approaches (e.g. template fitting) are fine for objects of well-known classes, alternative techniques have to be developed to determine those that do not fit. Therefore a classification scheme should be based on individual properties instead of fitting to a global model and therefore loose valuable information. An important issue when dealing with large data sets is the outlier detection which at the moment is often treated problem-orientated. Aims: In this paper we present a method to statistically estimate the redshift z based on a similarity approach. This allows us to determine redshifts in spectra in emission as well as in absorption without using any predefined model. Additionally we show how an estimate of the redshift based on single features is possible. As a consequence we are e.g. able to filter objects which show multiple redshift components. We propose to apply this general method to all similar problems in order to identify objects where traditional approaches fail. Methods: The redshift estimation is performed by comparing predefined regions in the spectra and applying a k nearest neighbor regression model for every predefined emission and absorption region, individually. Results: We estimated a redshift for more than 50% of the analyzed 16,000 spectra of our reference and test sample. The redshift estimate yields a precision for every individually tested feature that is comparable with the overall precision of the redshifts of SDSS. In 14 spectra we find a significant shift between emission and absorption or emission and emission lines. The results show already the immense power of this simple machine learning approach for investigating huge databases such as the SDSS.

description: In the dog, previous analyses of major histocompatibility complex (MHC) class I genes suggest a single polymorphic locus, Dog Leukocyte Antigen (DLA)-88. While 51 alleles have been reported, estimates of prevalence have not been made. We hypothesized that, within a breed, DLA-88 diversity would be restricted, and one or more dominant alleles could be identified. Accordingly, we determined allele usage in 47 Golden Retrievers and 39 Boxers. In each population, 10 alleles were found; 4 were shared. Seven novel alleles were identified. DLA-88*05101 and *50801 predominated in Golden Retrievers, while most Boxers carried *03401. In these breeds DLA-88 polymorphisms are limited and largely non-overlapping. The finding of highly prevalent alleles fulfills an important prerequisite for studying canine CD8+ T-cell responses.
Clean bodies in school: children’s relational experiences with discourses of hygiene in Tamil Nadu, India
Creators: name: Kannan, Smruthi Bala
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation combines feminist ethnography and archival research to study children’s spatial, material, and linguistic experiences with discourses of hygiene and sanitation in and around schools in urbanizing northern Tamil Nadu, India. Through ethnographic research with 10-15-year-old children across four schools, the study complicates the coupling of education and cleanliness that pervades national and transnational development narratives in India and the Tamil public sphere. Everyday tensions and negotiations that mark children’s subjectivities as ‘clean bodies in school’ are studied through four aspects -- hygiene curriculum in textbooks, school uniforms’ regulation and maintenance, children’s entanglement with plastics in environmental and embodied cleanliness, and verbal hygiene on the school campuses. The research critically contextualizes the complex working out of universal bio-medical narratives and post-colonial public health pedagogies within local socio-political, material, and ecological dynamics, including economic class, gender, caste, and sexuality. By tracing shifting and multiple cleanliness campaigns and children’s roles, negotiations, and representations around them, the study explores and proposes ‘clean bodies in school’ as a versatile framework to analyze the hybrid of children’s relational subjectivities, their lived experiences, and their representations, including historical discourses that surround the children’s bodies. This work denaturalizes figurations of the school as a clean space-time by situating it within a fluid and shifting terrain of materiality and symbols of cleanliness in post-colonial contexts. It argues that children as clean bodies are both produced by the school as well as participate in the production of the school as a clean entity.

description: Fibrin glue (FG) is used in a variety of clinical applications and in the laboratory for localized and sustained release of factors potentially important for tissue engineering. However, the effect of different fibrinogen concentrations on FG scaffold delivery of bioactive adeno-associated viruses (AAVs) has not been established. This study was performed to test the hypothesis that FG concentration alters AAV release profiles, which affect AAV bioavailability. Gene transfer efficiency of AAV-GFP released from FG was measured using HEK-293 cells. Bioactivity of AAV transforming growth factor-beta1 (TGF-β1) released from FG was assessed using the mink lung cell assay, and by measuring induction of cartilage-specific gene expression in human mesenchymal stem cells (hMSCs). Nondiluted FG had longer clotting times, smaller pore sizes, thicker fibers, and slower dissolution rate, resulting in reduced release of AAV. AAV release and gene transfer efficiency was higher with 25% and 50% FG than with the 75% and 100% FG. AAV-TGF-β1 released from dilute-FG transduced hMSCs, resulting in higher concentrations of bioactive TGF-β1 and greater upregulation of cartilage-specific gene expression compared with hMSC from undiluted FG. This study, showing improved release, transduction efficiency, and chondrogenic effect on hMSC of bioactive AAV-TGF-β1 released from diluted FG, provides information important to optimization of this clinically available scaffold for therapeutic gene delivery, both in cartilage regeneration and for other tissue engineering applications.

description: The existence of the thermodynamic limit in spin systems with short- and long-range interactions is established. We consider the infinite-volume limit with a fixed shape of the system. The variational expressions of the entropy density and the free energy density are obtained, which explicitly depend on the shape of the system. This shape dependence of thermodynamic functions implies the nonadditivity, which is one of the most important characteristics of long-range interacting systems.
