Polymorphs and Prodrugs and Salts (Oh My!): An Empirical Analysis of “Secondary” Pharmaceutical Patents

description: Background

While there has been much discussion by policymakers and stakeholders about the effects of “secondary patents” on the pharmaceutical industry, there is no empirical evidence on their prevalence or determinants. Characterizing the landscape of secondary patents is important in light of recent court decisions in the U.S. that may make them more difficult to obtain, and for developing countries considering restrictions on secondary patents.

Methodology/Principal Findings

We read the claims of the 1304 Orange Book listed patents on all new molecular entities approved in the U.S. between 1988 and 2005, and coded the patents as including chemical compound claims (claims covering the active molecule itself) and/or one of several types of secondary claims. We distinguish between patents with any secondary claims, and those with only secondary claims and no chemical compound claims (“independent” secondary patents).

We find that secondary claims are common in the pharmaceutical industry. We also show that independent secondary patents tend to be filed and issued later than chemical compound patents, and are also more likely to be filed after the drug is approved. When present, independent formulation patents add an average of 6.5 years of patent life (95% C.I.: 5.9 to 7.3 years), independent method of use patents add 7.4 years (95% C.I.: 6.4 to 8.4 years), and independent patents on polymorphs, isomers, prodrug, ester, and/or salt claims add 6.3 years (95% C.I.: 5.3 to 7.3 years). We also provide evidence that late-filed independent secondary patents are more common for higher sales drugs.

Conclusions/Significance

Policies and court decisions affecting secondary patenting are likely to have a significant impact on the pharmaceutical industry. Secondary patents provide substantial additional patent life in the pharmaceutical industry, at least nominally. Evidence that they are also more common for best-selling drugs is consistent with accounts of active “life cycle management” or “evergreening” of patent portfolios in the industry.
Can planetary instability explain the Kepler dichotomy?

description: The planet candidates discovered by the Kepler mission provide a rich sample to constrain the architectures and relative inclinations of planetary systems within approximately 0.5 AU of their host stars. We use the triple-transit systems from the Kepler 16-months data as templates for physical triple-planet systems and perform synthetic transit observations. We find that all the Kepler triple-transit and double-transit systems can be produced from the triple-planet templates, given a low mutual inclination of around five degrees. Our analysis shows that the Kepler data contains a population of planets larger than four Earth radii in single-transit systems that can not arise from the triple-planet templates. We explore the hypothesis that high-mass counterparts of the triple-transit systems underwent dynamical instability to produce a population of massive double-planet systems of moderately high mutual inclination. We perform N-body simulations of mass-boosted triple-planet systems and observe how the systems heat up and lose planets, most frequently by planet-planet collisions, yielding transits in agreement with the large planets in the Kepler single-transit systems. The resulting population of massive double-planet systems can nevertheless not explain the additional excess of low-mass planets among the observed single-transit systems and the lack of gas-giant planets in double-transit and triple-transit systems. Planetary instability of systems of triple gas-giant planets can be behind part of the dichotomy between systems hosting one or more small planets and those hosting a single giant planet. The main part of the dichotomy, however, is more likely to have arisen already during planet formation when the formation, migration or scattering of a massive planet, triggered above a threshold metallicity, suppressed the formation of other planets in sub-AU orbits.

description: Non-homologous end-joining (NHEJ) is the most prominent DNA double strand break (DSB) repair pathway in mammalian cells. PAXX is the newest NHEJ factor, which shares structural similarity with known NHEJ factors—XRCC4 and XLF. Here we report that PAXX is dispensable for physiological NHEJ in otherwise wild-type mice. Yet Paxx−/− mice require XLF and Xlf−/− mice require PAXX for end-ligation. As such, Xlf−/−Paxx−/− mice display severe genomic instability and neuronal apoptosis, which eventually lead to embryonic lethality. Despite their structural similarities, only Xlf−/− cells, but not Paxx−/− cells require ATM/DNA-PK kinase activity for end-ligation. Mechanistically, PAXX promotes the accumulation of KU at DSBs, while XLF enhances LIG4 recruitment without affecting KU dynamics at DNA breaks in vivo. Together these findings identify the molecular functions of PAXX in KU accumulation at DNA ends and reveal distinct, yet critically complementary functions of PAXX and XLF during NHEJ.

description: Multifunctional polymer-based composites have been widely used in various research and industrial applications, such as flexible and stretchable electronics and sensors and sensor-integrated smart structures. This study investigates the influence of particle coalescence on the mechanical and electrical properties of spherical nickel powder (SNP)/polydimethylsiloxane (PDMS) composites in which SNP was aligned using an external magnetic field. With the increase of the volume fraction of the SNP, the aligned SNP/PDMS composites exhibited a higher tensile strength and a lower ultimate strain. In addition, the composites with aligned SNP showed a lower percolation threshold and a higher electrical conductivity compared with those with randomly dispersed SNP. However, when the concentration of the SNP reached a certain level (40 vol. %), the anisotropy of the effective material property became less noticeable than that of the lower concentration (20 vol. %) composites due to the change of the microstructure of the particles caused by the coalescence of the particles at a high concentration. This work may provide rational methods for the fabrication of aligned composites.

Emotion management and transforming organizational culture: a case study of change and innovation in a multi-campus Canadian college

description: Bibliography: p. 227-247
description: This research is a descriptive exploratory ethnographic study of emotion management as it played out in the Kotter (1996b) model of organizational culture change employed at a multi-campus Canadian college. The research focused on three analytic foci. First, the study chronicled the Kotter culture change process as it was implemented at the college. Second, the research examined this change process in relation with Lopez's (2006) continuum of organizational support for emotion management. Third, this study explored subjective experiences of emotion management of members the Change Leadership Team. The author was employed at this college and served as a member on this team throughout the duration of the change process. Data were collected through participant experience ( combining participant observation and informal conversations amongst the author and colleagues at the college), in-depth, semistructured interviews with key informant participants and a review of institutional documents related to the change process. The need for organizational culture change was precipitated at this college by a history of intense intra-organizational distrust, depleted financial reserves and low morale throughout the college. The Kotter model of organizational culture change was implemented but only four of Kotter' s eight steps were achieved by the time this process stopped. Failure to complete all eight steps was correlated with contradictory expectations amongst college leadership regarding the roles of college administration and the Change Leadership Team, insufficient organizational support for the process, a preexisting organizational culture characterized by intense distrust, unrealistic expectations of the change process, subjective perceptions amongst members of the Change Leadership Team and insufficient organizational support for emotion management. Observing the implementation of this change model through the analytic lens of emotion management has shown a strong interplay between emotion, emotion management, the need for organizational culture change and the Kotter model of change as it was implemented in one multi-campus Canadian college. These findings may have significant impact for future use of the Kotter change process in the business sector, the educational sector, and other sectors.

Capillary filling with giant liquid/solid slip: dynamics of water uptake by carbon nanotubes

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: This article discusses the way the standard description of capillary filling dynamics has to be modified to account for liquid/solid slip in nanometric pores. It focuses in particular on the case of a large slip length compared to the pore size. It is shown that the liquid viscosity does not play a role, and that the flow is only controlled by the friction coefficient of the liquid at the wall. Moreover in the Washburn regime, the filling velocity does not depend on the tube radius. Finally, molecular dynamics simulations suggest that this standard description fails to describe the early stage of capillary filling of carbon nanotubes by water, since viscous dissipation at the tube entrance must be taken into account.

description: Background

Cutaneous leishmaniasis due to L. braziliensis (CL) is characterized by a positive delayed type hypersensitivity test (DTH) leishmania skin test (LST) and high IFN-γ production to soluble leishmania antigen (SLA). The LST is used for diagnosis of CL and for identification of individuals exposed to leishmania infection but without disease. The main aim of the present study was to identify markers of exposure to L. braziliensis infection.

Methodolgy/Principal Findings

This cohort study enrolled 308 household contacts (HC) of 76 CL index cases. HC had no active or past history of leishmaniasis. For the present cross-sectional study cytokines and chemokines were determined in supernatants of whole blood culture stimulated with SLA. Of the 308 HC, 36 (11.7%) had a positive LST but in these IFN-γ was only detected in 22 (61.1%). Moreover of the 40 HC with evidence of IFN-γ production only 22 (55%) had a positive LST. A total of 54 (17.5%) of 308 HC had specific immune response to SLA. Only a moderate agreement (Kappa = 0.52; 95% CI: 0.36–0.66) was found between LST and IFN-γ production. Moreover while enhancement of CXCL10 in cultures stimulated with SLA was observed in HC with DTH+ and IFN-γ+ and in patients with IFN-γ+ and DTH−, no enhancement of this chemokine was observed in supernatants of cells of HC with DTH+ and IFN-γ−.

Conclusions/Significance

This study shows that in addition of LST, the evaluation of antigen specific IFN-γ production should be performed to determine evidence of exposure to leishmania infection. Moreover it suggests that in some HC production of IFN-γ and CXCL10 are performed by cells not involved with DTH reaction.

Ghrelin Expression in the Mouse Pancreas Defines a Unique Multipotent Progenitor Population

description: Pancreatic islet cells provide the major source of counteractive endocrine hormones required for maintaining glucose homeostasis; severe health problems result when these cell types are insufficiently active or reduced in number. Therefore, the process of islet endocrine cell lineage allocation is critical to ensure there is a correct balance of islet cell types. There are four endocrine cell types within the adult islet, including the glucagon-producing alpha cells, insulin-producing beta cells, somatostatin-producing delta cells and pancreatic polypeptide-producing PP cells. A fifth islet cell type, the ghrelin-producing epsilon cells, is primarily found during gestational development. Although hormone expression is generally assumed to mark the final entry to a determined cell state, we demonstrate in this study that ghrelin-expressing epsilon cells within the mouse pancreas do not represent a terminally differentiated endocrine population. Ghrelin cells give rise to significant numbers of alpha and PP cells and rare beta cells in the adult islet. Furthermore, pancreatic ghrelin-producing cells are maintained in pancreata lacking the essential endocrine lineage regulator Neurogenin3, and retain the ability to contribute to cells within the pancreatic ductal and exocrine lineages. These results demonstrate that the islet ghrelin-expressing epsilon cells represent a multi-potent progenitor cell population that delineates a major subgrouping of the islet endocrine cell populations. These studies also provide evidence that many of hormone-producing cells within the adult islet represent heterogeneous populations based on their ontogeny, which could have broader implications on the regulation of islet cell ratios and their ability to effectively respond to fluctuations in the metabolic environment during development.

Stability, chaos and entrapment of stars in very wide pairs

description: The relative motion of stars and other celestial objects in very wide pairs, separated by distances of the order of 1 pc, is strongly influenced by the tidal gravitational potential of the Galaxy. The Coriolis component of the horizontal tidal force in the rotating reference frame tends to disrupt such marginally bound pairs. However, even extremely wide pairs of bodies can be bound over intervals of time comparable to the Hubble time, under appropriate initial conditions. Here we show that for arbitrary chosen initial coordinates of a pair of stars, there exists a volume of the space of initial velocity components where the orbits remain bound in the planar tidal field for longer than 10 Gyr, even though the initial separation is well outside the Jacobi radius. The boundary of this phase space of stable orbits is fractal, and the motion at the boundary conditions is clearly chaotic. We found that the pairs may remain confined for several Gyr, and then suddenly disintegrate due to a particularly close rendezvous. By reversing such long-term stable orbits, we find that entrapment of unrelated stars into wide pairs is possible, but should be quite rare. Careful analysis of precision astrometry surveys revealed that extremely wide pairs of stars are present in significant numbers in the Galaxy. These results are expected to help discriminating the cases of genuine binarity and chance entrapment, and to make inroads in testing the limits of Newtonian gravitation.

description: Eighty planetary systems of two or more planets are known to orbit stars other than the Sun. For most, the data can be sufficiently explained by non-interacting Keplerian orbits, so the dynamical interactions of these systems have not been observed. Here we present 4 sets of lightcurves from the Kepler spacecraft, which each show multiple planets transiting the same star. Departure of the timing of these transits from strict periodicity indicates the planets are perturbing each other: the observed timing variations match the forcing frequency of the other planet. This confirms that these objects are in the same system. Next we limit their masses to the planetary regime by requiring the system remain stable for astronomical timescales. Finally, we report dynamical fits to the transit times, yielding possible values for the planets' masses and eccentricities. As the timespan of timing data increases, dynamical fits may allow detailed constraints on the systems' architectures, even in cases for which high-precision Doppler follow-up is impractical.

description: The Uruguay Round trade negotiations were launched at the conference of the GATT contracting Parties in September 1986 at Punta del Este (Uruguay). The aim of these negotiations was a substantial overhaul of the world trading system; for the first time, multilateral disciplines were to be established at almost world-wide level for subjects such as intellectual property, trade-related investment measures and above all trade in services; at the same time, the functioning and institutional framework of the GATT system was to going be reviewed substantially. In this paper Fernando Perreau de Pininck presents the outcomes of the negotiations and draws some conclusions on the future of the liberalization process.

description: Galois cohomology is an important tool in algebra that can be used to classify isomorphism classes of algebraic objects over a field. In this thesis, we show that many objects of interest in algebra can be described in cohomological terms. Some objects that we discuss include quadratic forms, Pfister forms, G-crossed product algebras, and tuples of central simple algebras. We also provide cohomological interpretation to some induced maps that naturally occur in short exact sequences.

We study both focusing and defocusing case and in the limit of small speckle size (short correlated disordered beam) provide analytical asymptotes for the intensity probability distributions at the output facet. Additionally we provide a simple relation between the speckle sizes at the input and output of a focusing nonlinear waveguide. The results are of practical significance for the nonlinear Hanbury Brown and Twiss interferometry both in optical waveguides and Bose-Einstein condensates.

Functional Upregulation of Ca2+ -Activated K+ Channels in the Development of Substantia Nigra Dopamine Neurons

description: Many connections in the basal ganglia are made around birth when animals are exposed to a host of new affective, cognitive, and sensori-motor stimuli. It is thought that dopamine modulates cortico-striatal synapses that result in the strengthening of those connections that lead to desired outcomes. We propose that there must be a time before which stimuli cannot be processed into functional connections, otherwise it would imply an effective link between stimulus, response, and reward in uterus. Consistent with these ideas, we present evidence that early in development dopamine neurons are electrically immature and do not produce high-frequency firing in response to salient stimuli. We ask first, what makes dopamine neurons immature? and second, what are the implications of this immaturity for the basal ganglia? As an answer to the first question, we find that at birth the outward current is small (3nS-V), insensitive to , TEA, BK, and SK blockers. Rapidly after birth, the outward current increases to 15nS-V and becomes sensitive to , TEA, BK, and SK blockers. We make a detailed analysis of the kinetics of the components of the outward currents and produce a model for BK and SK channels that we use to reproduce the outward current, and to infer the geometrical arrangement of BK and  channels in clusters. In the first cluster, T-type and BK channels are coupled within distances of 20 nm (200 Å). The second cluster consists of L-type  and BK channels that are spread over distances of at least 60 nm. As for the second question, we propose that early in development, the mechanism of action selection is in a “locked-in” state that would prevent dopamine neurons from reinforcing cortico-striatal synapses that do not have a functional experiential-based value.
Switch-reference as anaphora: a modular account
Creators: name: De Camargo Silva Tavares De Souza, Livia
Publisher: name: No Publisher Supplied
Year: 2020

description: For over 50 years, linguists have raised questions about the nature of switch-reference (SR): is it a syntactic or a semantic phenomenon? One of my main goals in this dissertation is to argue that SR is one of grammar’s multiple ways to express anaphora, and that as such, it cannot be characterized as simply syntactic or semantic: it involves coordinated work from all modules of grammar. My main source of primary data is the Yawanawa language, which along with its Panoan relatives, has an especially rich paradigm of SR: not only does it have the same-subject (SS) and different-subject (DS) markers that are found in a number of SR languages around the world, but also it includes the rare object=subject (OS) marker, which has not been documented outside the Panoan family (Valenzuela 2003; Fleck 2003; Zariquiey-Biondi 2011; Baker and Camargo Souza 2019, 2020; Clem 2019; Neely 2019). I argue that the existence of the OS morpheme supports the view that SR has a strong syntactic component (Finer 1984 and much subsequent work): it needs to make reference to the grammatical functions of subject and object. However, syntax is not all there is to it. SR is not construction- specific and as such, it gives rise to different types of coconstrual. The nature of the coconstrual is up to semantics to define, according to the syntactic structure that isshipped to interpretation, and the types of nominal expressions therein. The possible coconstruals we find are not SR-exclusive: they are the ones that are made available by Universal Grammar and therefore familiar to us.I argue that the syntactic component of SR is Agree-based (Chomsky 2000, 2001), which at first may seem somewhat paradoxical because SR morphemes do not expone the phi-features of DPs it coconstrues. I solve this apparent paradox by proposing that when Agree-link obtains in a certain configuration but Agree-copy does not, this leads the semantic module to interpret the links as a coconstrual relation. As such, we get Agree without agreement. More specifically, the configuration is one in which a single syntactic terminal is linked to two DPs. When it comes to interpretation, I argue that whenever c-command obtains between the DPs being coconstrued, we get bound variable anaphora; when it does not, we get dynamic binding or coreference, depending on the types of nominal expressions involved. I find further support for my argument that SR expresses familiar types of referential dependencies by exploring patterns of anaphora to sets with quantified and plural referents (c.f. Thomas 2019). I show that what is special about SR languages is that they ‘choose’ to morpho-syntactically express certain types of cross-clausal anaphora, not that they express patterns of anaphora that are unique or unattested crosslinguistically.
Ending Neglect of Older People in the Response to Humanitarian Emergencies

description: Older people make up a significant and growing number of those affected by humanitarian crises, yet they are often not sought out or prioritised within the humanitarian response. Humanitarian agencies, donors, and international bodies neglect older people's health and nutrition. The gaps in knowledge and research about the needs of older people in emergencies are considerable. Older people are not monitored in emergencies and they are not prioritised despite evidence of disproportionate mortality and morbidity in this group. We call for policy changes by humanitarian agencies and donors to ensure that the needs of this vulnerable group are met.

Publisher: name: figshare
Year: 2023
Subjects: classificationCode: 390105
subject: Environmental education curriculum and pedagogy

description: This lesson plan is appropriate for high school upperclassmen and college underclassmen and was co-developed by scientists and educators. It guides students through an authentic science practice in an environmental sciences context. The Chesapeake Bay and the Virginia Coast Reserve are two estuaries located in Coastal Virginia. Ecosystem health in these estuaries can be measured by measuring environmental drivers, or variables. Students follow the scientific process and collect data at field sites in both estuaries. Publicly available data from the Virginia Coast Reserve Long-Term Ecological Research Site (VCR-LTER) and existing outreach resources about the Chesapeake Bay are used to help students make sense of their data.

description: We measure the excitation spectrum of a dipolar Chromium Bose Einstein Condensate with Raman-Bragg spectroscopy. The energy spectrum depends on the orientation of the dipoles with respect to the excitation momentum, demonstrating an anisotropy which originates from the dipole-dipole interactions between the atoms. We compare our results with the Bogoliubov theory based on the local density approximation, and, at large excitation wavelengths, with numerical simulations of the time dependent Gross-Pitaevskii equation. Our results show an anisotropy of the speed of sound

description: Urbanization often occurs in an unplanned and uneven manner, resulting in profound changes in patterns of land cover and land use. Understanding these changes is fundamental for devising environmentally responsible approaches to economic development in the rapidly urbanizing countries of the emerging world. One indicator of urbanization is built-up land cover that can be detected and quantified at scale using satellite imagery and cloud-based computational platforms. This process requires reliable and comprehensive ground-truth data for supervised classification and for validation of classification products. We present a new dataset for India, consisting of 21,030 polygons from across the country that were manually classified as “built-up” or “not built-up,” which we use for supervised image classification and detection of urban areas. As a large and geographically diverse country that has been undergoing an urban transition, India represents an ideal context to develop and test approaches for the detection of features related to urbanization. We perform the analysis in Google Earth Engine (GEE) using three types of classifiers, based on imagery from Landsat 7 and Landsat 8 as inputs. The methodology produces high-quality maps of built-up areas across space and time. Although the dataset can facilitate supervised image classification in any platform, we highlight its potential use in GEE for temporal large-scale analysis of the urbanization process. Our methodology can easily be applied to other countries and regions.
Accurate determination of the Gaussian transition in spin-1 chains with single-ion anisotropy

description: The Gaussian transition in the spin-one Heisenberg chain with single-ion anisotropy is extremely difficult to treat, both analytically and numerically. We introduce an improved DMRG procedure with strict error control, which we use to access very large systems. By considering the bulk entropy, we determine the Gaussian transition point to 4-digit accuracy, $D_{c}/J = 0.96845(8)$, resolving a long-standing debate in quantum magnetism. With this value, we obtain high-precision data for the critical behavior of quantities including the ground-state energy, gap, and transverse string-order parameter, and for the critical exponent, $ν= 1.472(2)$. Applying our improved technique at $J_{z} = 0.5$ highlights essential differences in critical behavior along the Gaussian transition line.

description: Proyecto Corales is a volunteer committee in the Bay of Samara that seeks to restore the coral reef in the area. With support from the Instituto Nacional de Aprendizaje (INA), the group is the first community driven coral gardening project. In addition to performing coral gardening for the rehabilitation of the reef, the group seeks to educate the local community and society at large and to perform activities that will mitigate the decline of the reef. While many of the activities are planned, their full implementation has not been carried out. Because of this the analysis attempts to capture present and future impacts. The analysis presented here was carried out adapting the SLCA methodology recommended by the UN and SETAC to the local realities. Primary data gathering was done through focus groups with different stakeholders and this was complemented with desktop research. The analysis finds that Proyecto Corales provides significant beneficial social impacts. Successful restoration can add up to $350,000 per ha per year in economic benefits, while the group is increasing the protection of cultural assets, providing increases in skills and training, and generating access to local natural resources. However, the group needs to focus on its engagement with local community to increase awareness and transparency. This will not only increase their beneficial social impacts but increase their chances for success for other planned activities.
