Musicalizing history

While there have been growing calls for historians to listen to the past, there are also significant barriers to integrating music in particular into broader historical practice. This article reflects on both the gains and difficulties of this integration, moving from an interrogation of the category of ‘music’ to three case studies. These concern musical terms, compositional practices and cultures from the fifteenth to eighteenth centuries, revisiting some key debates in musicology: first, the highly-charged language of ‘sweetness’ deployed in the fifteenth century; second, connections discerned in nineteenth-century music history between medieval polyphony and contemporary attitudes towards time and authority; and, third, debate over the anti-Jewish implications of Handel’s music, which we approach through his Dixit dominus and a history of psalm interpretation stretching back to late antiquity. Through these case studies, we suggest the contribution of music to necessarily interdisciplinary fields including the study of temporality and emotions, but also explore how a historical hermeneutic with a long pedigree – ‘diversity of times’ (diversitas temporum) – might help to reframe arguments about musical interpretation. The article concludes by arguing that the very difficulty and slipperiness of music as a source can encourage properly reflective historical practice

Archeological Of The Proposed FM 1626 Pass-Through Toll Project From Ranch-To-Market 967 To Farm-To-Market 2770 In Hays County, Texas

Hicks & Company archeologists conducted an intensive, 100-percent linear archeological survey of approximately 3.3 miles of proposed expansions to Farm-to-Market (FM) 1626 west of the city of Buda, Hays County, Texas. The survey was conducted between July 2008 and October 2016 for compliance with the Antiquities Code of Texas and Section 106 of the National Historic Preservation Act on behalf of Hays County, the project engineer Klotz Associates, and the Texas Department of Transportation (TxDOT). The Area of Potential Effects (APE) for the proposed project is composed of 54.3 acres of existing right of way and 8.08 acres of proposed expanded right of way (measuring 62.38 acres of existing plus proposed expanded right of way), and approximately 1.07 acres of temporary construction easements located outside of the existing or proposed right of way. While the proposed expanded right of way corridor has been determined, the project engineer requested that a 200-foot-wide corridor be investigated (extending 100 feet in either direction from the existing centerline) to allow for flexibility in road design, potential utility relocation, and other possible areas of concern, resulting in a total of approximately 81 acres of land surveyed. Investigations were coordinated with the Texas Historical Commission through TxDOT under Texas Antiquities Committee Permit Number 4981. On three occasions between July 28, 2008, and August 10, 2009 Hicks & Company archeologists conducted an intensive linear archeological survey of the proposed FM 1626 improvements project west of the city of Buda, Texas, on behalf of Hays County and TxDOT, returning to the field on January 21, 2016 to survey for proposed temporary construction easements located outside of the existing right of way or proposed new right of way, and again on October 26, 2016 to survey proposed new right of way in previously inaccessible parcels, completing the survey. The survey consisted of pedestrian inspection supplemented by shovel testing (N=102) and mechanical backhoe trench excavations (N=7) in the area north of Onion Creek. One backhoe trench excavated on the north bank of Onion Creek was positive for two pieces of lithic debitage, along with 32 shovel tests throughout the APE that were positive for cultural materials. One previously unrecorded site (Site 41HY449) was documented during the survey. This prehistoric surficial scatter does not meet the significance criteria for listing on the National Register of Historic Places (NRHP) or as a State Antiquities Landmark (SAL). In addition to this newly recorded site, archeologists visited elements of seven previously recorded sites (Sites 41HY199-202, 41HY209-210, and 41HY219) within the APE. Elements of one of these, Site 41HY200, could not be found within the archeological APE. Of these, only elements of Site 41HY201 are considered to have potential to deem the site eligible for inclusion on the NRHP or for designation as an SAL. The project engineer has altered plans in the vicinity of the site to avoid impacts to those resources. All other sites were found to be heavily disturbed, no longer extant, or within shallow surficial contexts atop bedrock with limited research value. Archeologists also visited the expansion areas adjacent to historic Barton Cemetery. Although the cemetery lies in close proximity to the APE, the County proposes no expansions in the immediate vicinity of the cemetery beyond a proposed retaining wall with riprap slope within the existing right of way outside the cemetery. This retaining wall is to be constructed approximately ten feet within current existing right of way. By design, retaining walls planned for this project will be fixed in place to concrete leveling pads set in place on top of the current grade and supported by earth reinforcement buildup of imported fill material. During survey, an overgrown road or trail that follows the current cemetery fenceline reinforces the assumption that the existing cemetery boundary served as the historic boundary as well, significantly reducing the potential for unmarked burials to be located within the current archeological APE. Construction within the APE is recommended to proceed with no further cultural resources investigation. The current investigations followed a no-collection policy. All projectrelated records, forms, and photographs will be permanently housed at the Texas Archeological Research Laboratory in Austin, Texas

Myeloid-derived suppressor cells inhibit T cell activation through nitrating LCK in mouse cancers

Potent immunosuppressive mechanisms within the tumor microenvironment contribute to the resistance of aggressive human cancers to immune checkpoint blockade (ICB) therapy. One of the main mechanisms for myeloid-derived suppressor cells (MDSCs) to induce T cell tolerance is through secretion of reactive nitrogen species (RNS), which nitrates tyrosine residues in proteins involved in T cell function. However, so far very few nitrated proteins have been identified. Here, using a transgenic mouse model of prostate cancer and a syngeneic cell line model of lung cancer, we applied a nitroproteomic approach based on chemical derivation of 3-nitrotyrosine and identified that lymphocyte-specific protein tyrosine kinase (LCK), an initiating tyrosine kinase in the T cell receptor signaling cascade, is nitrated at Tyr394 by MDSCs. LCK nitration inhibits T cell activation, leading to reduced interleukin 2 (IL2) production and proliferation. In human T cells with defective endogenous LCK, wild type, but not nitrated LCK, rescues IL2 production. In the mouse model of castration-resistant prostate cancer (CRPC) by prostate-specific deletion of Pten, p53, and Smad4, CRPC is resistant to an ICB therapy composed of antiprogrammed cell death 1 (PD1) and anticytotoxic-T lymphocyte-associated protein 4 (CTLA4) antibodies. However, we showed that ICB elicits strong anti-CRPC efficacy when combined with an RNS neutralizing agent. Together, these data identify a previously unknown mechanism of T cell inactivation by MDSC-induced protein nitration and illuminate a clinical path hypothesis for combining ICB with RNS-reducing agents in the treatment of CRPC

Understanding Paramagnetic Spin Correlations in the Spin-Liquid Pyrochlore Tb2Ti2O7

Recent elastic and inelastic neutron scattering studies of the highly frustrated pyrochlore antiferromagnet Tb2Ti2O7 have shown some very intriguing features that cannot be modeled by the local classical Ising model, naively expected to describe this system at low temperatures. Using the random phase approximation to take into account fluctuations between the ground state doublet and the first excited doublet, we successfully describe the elastic neutron scattering pattern and dispersion relations in Tb2Ti2O7, semi-quantitatively consistent with experimental observations.Comment: revtex4, 4 pages, 1 Color+ 2 BW figure

Perceived and Actual Breast Cancer Risk

Perceived risk can influence health behaviors. Studies using various populations and breast cancer risk bias assessment methods have identified both risk over- and underestimation. Among 1803 women in primary care settings, 47 percent were at average epidemiologic risk (Gail-calculated relative risk ±50 percent of age-adjusted population average) and 55 percent perceived themselves to be at average risk (compared to same-age others) but there were mismatches or ‘biases’: 31 percent underestimated personal risk; 26 percent overestimated. Multiple logistic regression revealed that smokers were more likely to overestimate risk. Overestimation decreased with more education. Mammography use did not independently predict perception bias but, among never-screened women aged over 40 years, those contemplating mammograms were most likely to overestimate risk; precontemplators were most likely to underestimate. Implications for research and intervention are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66881/2/10.1177_135910539800300203.pd

Profiling of human acquired immunity against the salivary proteins of Phlebotomus papatasi reveals clusters of differential immunoreactivity

Champion, et al. 2014. “Profiling of Human Acquired Immunity Against the Salivary Proteins of Phlebotomus Papatasi Reveals Clusters of Differential Immunoreactivity.” The American Journal of Tropical Medicine and Hygiene 90 (5): 923–38. https://doi.org/10.4269/ajtmh.13-0130.Phlebotomus papatasi sand flies are among the primary vectors of Leishmania major parasites from Morocco to the Indian subcontinent and from southern Europe to central and eastern Africa. Antibody-based immunity to sand fly salivary gland proteins in human populations remains a complex contextual problem that is not yet fully understood. We profiled the immunoreactivities of plasma antibodies to sand fly salivary gland sonicates (SGSs) from 229 human blood donors residing in different regions of sand fly endemicity throughout Jordan and Egypt as well as 69 US military personnel, who were differentially exposed to P. papatasi bites and L. major infections in Iraq. Compared with plasma from control region donors, antibodies were significantly immunoreactive to five salivary proteins (12, 26, 30, 38, and 44 kDa) among Jordanian and Egyptian donors, with immunoglobulin G4 being the dominant anti-SGS isotype. US personnel were significantly immunoreactive to only two salivary proteins (38 and 14 kDa). Using k-means clustering, donors were segregated into four clusters distinguished by unique immunoreactivity profiles to varying combinations of the significantly immunogenic salivary proteins. SGS-induced cellular proliferation was diminished among donors residing in sand fly-endemic regions. These data provide a clearer picture of human immune responses to sand fly vector salivary constituents

Control and Manipulation of Pathogens with an Optical Trap for Live Cell Imaging of Intercellular Interactions

The application of live cell imaging allows direct visualization of the dynamic interactions between cells of the immune system. Some preliminary observations challenge long-held beliefs about immune responses to microorganisms; however, the lack of spatial and temporal control between the phagocytic cell and microbe has rendered focused observations into the initial interactions of host response to pathogens difficult. This paper outlines a method that advances live cell imaging by integrating a spinning disk confocal microscope with an optical trap, also known as an optical tweezer, in order to provide exquisite spatial and temporal control of pathogenic organisms and place them in proximity to host cells, as determined by the operator. Polymeric beads and live, pathogenic organisms (Candida albicans and Aspergillus fumigatus) were optically trapped using non-destructive forces and moved adjacent to living cells, which subsequently phagocytosed the trapped particle. High resolution, transmitted light and fluorescence-based movies established the ability to observe early events of phagocytosis in living cells. To demonstrate the broad applicability of this method to immunological studies, anti-CD3 polymeric beads were also trapped and manipulated to form synapses with T cells in vivo, and time-lapse imaging of synapse formation was also obtained. By providing a method to exert fine control of live pathogens with respect to immune cells, cellular interactions can be captured by fluorescence microscopy with minimal perturbation to cells and can yield powerful insight into early responses of innate and adaptive immunity.National Institute of Biomedical Imaging and Bioengineering (U.S.) (grant T32EB006348)Massachusetts General Hospital (Department of Medicine Internal Funds)Center for Computational and Integrative Biology (Development fund)Center for Computational and Integrative Biology (AI062773)Center for Computational and Integrative Biology (grant AI062773)Center for Computational and Integrative Biology (grant DK83756)Center for Computational and Integrative Biology (grant DK 043351)National Institute of Allergy and Infectious Diseases (U.S.)National Institutes of Health (U.S.) (grant AI057999

Engaging diverse underserved communities to bridge the mammography divide

<p>Abstract</p> <p>Background</p> <p>Breast cancer screening continues to be underutilized by the population in general, but is particularly underutilized by traditionally underserved minority populations. Two of the most at risk female minority groups are American Indians/Alaska Natives (AI/AN) and Latinas. American Indian women have the poorest recorded 5-year cancer survival rates of any ethnic group while breast cancer is the number one cause of cancer mortality among Latina women. Breast cancer screening rates for both minority groups are near or at the lowest among all racial/ethnic groups. As with other health screening behaviors, women may intend to get a mammogram but their intentions may not result in initiation or follow through of the examination process. An accumulating body of research, however, demonstrates the efficacy of developing 'implementation intentions' that define when, where, and how a specific behavior will be performed. The formulation of intended steps in addition to addressing potential barriers to test completion can increase a person's self-efficacy, operationalize and strengthen their intention to act, and close gaps between behavioral intention and completion. To date, an evaluation of the formulation of implementation intentions for breast cancer screening has not been conducted with minority populations.</p> <p>Methods/Design</p> <p>In the proposed program, community health workers will meet with rural-dwelling Latina and American Indian women one-on-one to educate them about breast cancer and screening and guide them through a computerized and culturally tailored "implementation intentions" program, called <it>Healthy Living Kansas - Breast Health</it>, to promote breast cancer screening utilization. We will target Latina and AI/AN women from two distinct rural Kansas communities. Women attending community events will be invited by CHWs to participate and be randomized to either a mammography "implementation intentions" (<b>MI</b>^<b>2</b>) intervention or a comparison general breast cancer prevention informational intervention (<b>C</b>). CHWs will be armed with notebook computers loaded with our Healthy Living Kansas - Breast Health program and guide their peers through the program. Women in the <b>MI</b>^{<b>2 </b>}condition will receive assistance with operationalizing their screening intentions and identifying and addressing their stated screening barriers with the goal of guiding them toward accessing screening services near their community. Outcomes will be evaluated at 120-days post randomization via self-report and will include mammography utilization status, barriers, and movement along a behavioral stages of readiness to screen model.</p> <p>Discussion</p> <p>This highly innovative project will be guided and initiated by AI/AN and Latina community members and will test the practical application of emerging behavioral theory among minority persons living in rural communities.</p> <p>Trial Registration</p> <p>ClinicalTrials (NCT): <a href="http://www.clinicaltrials.gov/ct2/show/NCT01267110">NCT01267110</a></p

Comparative Genomic Characterization of Francisella tularensis Strains Belonging to Low and High Virulence Subspecies

Tularemia is a geographically widespread, severely debilitating, and occasionally lethal disease in humans. It is caused by infection by a gram-negative bacterium, Francisella tularensis. In order to better understand its potency as an etiological agent as well as its potential as a biological weapon, we have completed draft assemblies and report the first complete genomic characterization of five strains belonging to the following different Francisella subspecies (subsp.): the F. tularensis subsp. tularensis FSC033, F. tularensis subsp. holarctica FSC257 and FSC022, and F. tularensis subsp. novicida GA99-3548 and GA99-3549 strains. Here, we report the sequencing of these strains and comparative genomic analysis with recently available public Francisella sequences, including the rare F. tularensis subsp. mediasiatica FSC147 strain isolate from the Central Asian Region. We report evidence for the occurrence of large-scale rearrangement events in strains of the holarctica subspecies, supporting previous proposals that further phylogenetic subdivisions of the Type B clade are likely. We also find a significant enrichment of disrupted or absent ORFs proximal to predicted breakpoints in the FSC022 strain, including a genetic component of the Type I restriction-modification defense system. Many of the pseudogenes identified are also disrupted in the closely related rarely human pathogenic F. tularensis subsp. mediasiatica FSC147 strain, including modulator of drug activity B (mdaB) (FTT0961), which encodes a known NADPH quinone reductase involved in oxidative stress resistance. We have also identified genes exhibiting sequence similarity to effectors of the Type III (T3SS) and components of the Type IV secretion systems (T4SS). One of the genes, msrA2 (FTT1797c), is disrupted in F. tularensis subsp. mediasiatica and has recently been shown to mediate bacterial pathogen survival in host organisms. Our findings suggest that in addition to the duplication of the Francisella Pathogenicity Island, and acquisition of individual loci, adaptation by gene loss in the more recently emerged tularensis, holarctica, and mediasiatica subspecies occurred and was distinct from evolutionary events that differentiated these subspecies, and the novicida subspecies, from a common ancestor. Our findings are applicable to future studies focused on variations in Francisella subspecies pathogenesis, and of broader interest to studies of genomic pathoadaptation in bacteria
