High-pressure behaviour of zoisite

A high-pressure single-crystal X-ray diffraction (XRD) study has been carried out on two natural zoisite samples Ca 2Al 3-xFexSi 3O 12OH, one Fe-free (x = 0) and one Fe-rich (x = 0.12). The unit-cell parameters were determined for the Fe-free sample at 18 different pressures up to 7.76 GPa and for the Fe-rich sample at 13 different pressures up to 7.63 GPa. The P(V) data for both of the samples were fitted by a third-order Birch-Murnaghan equation of state (BM3 EoS). The equation of state coefficients are: V 0 = 903.39(5) \uc5 3, K T0 = 122.1(7) GPa, and K\u2032 0 = 6.8(2) for the Fe-free sample and V 0 = 906.95(5) \uc5 3, K T0 = 119.1(7) GPa, and K\u2032 0 = 7.3(2) for the Fe-rich sample. This shows that the addition of Fe in to the crystal structure of zoisite leads to a slight softening of the structure. Both compositions exhibit axial compressibilities \u3b2c > \u3b2 a 6b \u3b2 b, with the compressibilities of the a and b axes of the two samples being indistinguishable. The softening of the bulk modulus of zoisite with Fe content follows from softening of the c-axis of the structure. A high-pressure structural study of the Fe-free sample showed that the main compression mechanisms in the structure are the compression of soft inter-octahedral distance along [001] and soft intra-octahedral distances along [010] directions, while along [100] the main compression occurs because of the compression of stiff intra-octahedral distances. The substitution of Fe on to the M3 octahedral site of the structure leads to an increase of the intra-octahedral distance of the M3 that triggers the rotation of M12 and therefore leads to the softening of the M12 inter-octahedral distances that accounts for the softening of the c-axis of the structure

La Pisquería

Debido a la coyuntura que vivimos actualmente, no debería sorprendernos los altos niveles de estrés que venimos acumulando debido a la pandemia, aislamiento, incertidumbre, pérdida de trabajo entre otros. Toda esta situación llevó a que el comportamiento del consumidor cambiara. Recordemos que normalmente el consumidor frecuentaba los autoservicios para realizar sus compras. Sin embargo, hemos podido evidenciar el cambio del comportamiento de compra de los peruanos, hoy en día este está orientado a las compras online y bajo las diferentes plataformas existentes. Así como, este cambio en el comportamiento de compra, también se dieron cambios en el consumo de bebidas alcohólicas, antes de la pandemia recordemos que una de las bebidas preferidas o de más consumo por los peruanos era la cerveza, no obstante, esto cambió durante este tiempo, la cerveza ya no es una de las bebidas alcohólicas más consumidas entre nosotros y es desplazada por el consumo de whisky, vino y pisco. Ante estos cambios, hemos creado La Pisquería, un negocio donde el consumidor podrá adquirir los mejores piscos artesanales de las regiones pisqueras avalada por expertos y reconocidos catadores, quienes validarán la calidad, aroma y sabor del producto. Todo ello sin la necesidad de salir de sus hogares y verse expuestos a contraer el COVID-19, ya que, podrán adquirir nuestro producto y experimentar una nueva experiencia de compra, a través de nuestras plataformas digitales.Due to the situation we live in today, we should not be surprised by the high levels of stress that we have accumulated due to the pandemic, isolation, uncertainty, loss of work among others. This whole situation led to consumer behavior changing. Let's remember that the consumer normally frequented the self-service to make their purchases. However, we have been able to show the change in the buying behavior of Peruvians, today this is oriented to online purchases and under the different platforms existing. Just as, this change in the buying behavior, there were also changes in the consumption of alcoholic beverages, before the pandemic we remember that one of the drinks preferred or most consumed by Peruvians was beer, however, this changed during this time, beer is no longer one of the most consumed alcoholic beverages among us and is displaced by the consumption of whisky , wine and pisco. In the face of these changes, we have created La Pisquería, a business where the consumer can acquire the best artisanal piscos of the pisquera regions endorsed by experts and renowned tasters, who will validate the quality, aroma and taste of the product. All this without the need to leave their homes and be exposed to contracting COVID-19, since, they will be able to acquire our product and experience a new shopping experience, through our digital platforms.Trabajo de investigació

Does Reproductive Justice Demand Insurance Coverage for IVF?

This paper comes out of a panel honoring the work of Anne Donchin (1940-2014), which took place at the 2016 Congress of the International Network on Feminist Approaches to Bioethics (FAB) in Edinburgh. My general aim is to highlight the contributions Anne made to feminist bioethics, and to feminist reproductive ethics in particular. My more specific aim, however, is to have a kind of conversation with Anne, through her work, about whether reproductive justice could demand insurance coverage for in vitro fertilization. I quote liberally from Anne’s work for this purpose, but also to shower the reader with her words, reminding those of us who knew her well what a wonderful colleague she was

The Genomic and Immune Landscapes of Lethal Metastatic Breast Cancer

TCR repertoire; Breast cancer; Clade mutationsRepertori TCR; Càncer de mama; Mutacions cladeRepertorio TCR; Cáncer de mama; Mutaciones cladoThe detailed molecular characterization of lethal cancers is a prerequisite to understanding resistance to therapy and escape from cancer immunoediting. We performed extensive multi-platform profiling of multi-regional metastases in autopsies from 10 patients with therapy-resistant breast cancer. The integrated genomic and immune landscapes show that metastases propagate and evolve as communities of clones, reveal their predicted neo-antigen landscapes, and show that they can accumulate HLA loss of heterozygosity (LOH). The data further identify variable tumor microenvironments and reveal, through analyses of T cell receptor repertoires, that adaptive immune responses appear to co-evolve with the metastatic genomes. These findings reveal in fine detail the landscapes of lethal metastatic breast cancer

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures.

Pan-Cancer Analysis of lncRNA Regulation Supports Their Targeting of Cancer Genes in Each Tumor Context

Long noncoding RNAs (lncRNAs) are commonly dys-regulated in tumors, but only a handful are known toplay pathophysiological roles in cancer. We inferredlncRNAs that dysregulate cancer pathways, onco-genes, and tumor suppressors (cancer genes) bymodeling their effects on the activity of transcriptionfactors, RNA-binding proteins, and microRNAs in5,185 TCGA tumors and 1,019 ENCODE assays.Our predictions included hundreds of candidateonco- and tumor-suppressor lncRNAs (cancerlncRNAs) whose somatic alterations account for thedysregulation of dozens of cancer genes and path-ways in each of 14 tumor contexts. To demonstrateproof of concept, we showed that perturbations tar-geting OIP5-AS1 (an inferred tumor suppressor) andTUG1 and WT1-AS (inferred onco-lncRNAs) dysre-gulated cancer genes and altered proliferation ofbreast and gynecologic cancer cells. Our analysis in-dicates that, although most lncRNAs are dysregu-lated in a tumor-specific manner, some, includingOIP5-AS1, TUG1, NEAT1, MEG3, and TSIX, synergis-tically dysregulate cancer pathways in multiple tumorcontexts

Spatial Organization and Molecular Correlation of Tumor-Infiltrating Lymphocytes Using Deep Learning on Pathology Images

Beyond sample curation and basic pathologic characterization, the digitized H&E-stained images of TCGA samples remain underutilized. To highlight this resource, we present mappings of tumorinfiltrating lymphocytes (TILs) based on H&E images from 13 TCGA tumor types. These TIL maps are derived through computational staining using a convolutional neural network trained to classify patches of images. Affinity propagation revealed local spatial structure in TIL patterns and correlation with overall survival. TIL map structural patterns were grouped using standard histopathological parameters. These patterns are enriched in particular T cell subpopulations derived from molecular measures. TIL densities and spatial structure were differentially enriched among tumor types, immune subtypes, and tumor molecular subtypes, implying that spatial infiltrate state could reflect particular tumor cell aberration states. Obtaining spatial lymphocytic patterns linked to the rich genomic characterization of TCGA samples demonstrates one use for the TCGA image archives with insights into the tumor-immune microenvironment

Pan-cancer Alterations of the MYC Oncogene and Its Proximal Network across the Cancer Genome Atlas

Although theMYConcogene has been implicated incancer, a systematic assessment of alterations ofMYC, related transcription factors, and co-regulatoryproteins, forming the proximal MYC network (PMN),across human cancers is lacking. Using computa-tional approaches, we define genomic and proteo-mic features associated with MYC and the PMNacross the 33 cancers of The Cancer Genome Atlas.Pan-cancer, 28% of all samples had at least one ofthe MYC paralogs amplified. In contrast, the MYCantagonists MGA and MNT were the most frequentlymutated or deleted members, proposing a roleas tumor suppressors.MYCalterations were mutu-ally exclusive withPIK3CA,PTEN,APC,orBRAFalterations, suggesting that MYC is a distinct onco-genic driver. Expression analysis revealed MYC-associated pathways in tumor subtypes, such asimmune response and growth factor signaling; chro-matin, translation, and DNA replication/repair wereconserved pan-cancer. This analysis reveals insightsinto MYC biology and is a reference for biomarkersand therapeutics for cancers with alterations ofMYC or the PMN

HDP—A Novel Heme Detoxification Protein from the Malaria Parasite

When malaria parasites infect host red blood cells (RBC) and proteolyze hemoglobin, a unique, albeit poorly understood parasite-specific mechanism, detoxifies released heme into hemozoin (Hz). Here, we report the identification and characterization of a novel Plasmodium Heme Detoxification Protein (HDP) that is extremely potent in converting heme into Hz. HDP is functionally conserved across Plasmodium genus and its gene locus could not be disrupted. Once expressed, the parasite utilizes a circuitous “Outbound–Inbound” trafficking route by initially secreting HDP into the cytosol of infected RBC. A subsequent endocytosis of host cytosol (and hemoglobin) delivers HDP to the food vacuole (FV), the site of Hz formation. As Hz formation is critical for survival, involvement of HDP in this process suggests that it could be a malaria drug target
