This heterogeneity likely drives pronounced spatial variation in BLA computation and function.APC/C-mediated proteolysis of cyclin B and securin promotes anaphase entry, inactivating CDK1 and permitting chromosome segregation, respectively. Reduction of CDK1 activity relieves inhibition of the CDK1-counteracting phosphatases PP1 and PP2A-B55, allowing wide-spread dephosphorylation of substrates. Meanwhile, continued APC/C activity promotes proteolysis of other mitotic regulators. Together, these activities orchestrate a complex series of events during mitotic exit. However, the relative importance of regulated proteolysis and dephosphorylation in dictating the order and timing of these events remains unclear. Using high temporal-resolution proteomics, we compare the relative extent of proteolysis and protein dephosphorylation. This reveals highly-selective rapid proteolysis of cyclin B, securin and geminin at the metaphase-anaphase transition, followed by slow proteolysis of other substrates. Dephosphorylation requires APC/C-dependent destruction of cyclin B and was resolved into PP1-dependent categories with unique sequence motifs. We conclude that dephosphorylation initiated by selective proteolysis of cyclin B drives the bulk of changes observed during mitotic exit.New evidence that neighboring communities of bonobos hunt different prey species, despite extensive overlaps in where they live and hunt, is difficult to explain without invoking cultural factors.Citrate, α-ketoglutarate and succinate are TCA cycle intermediates that also play essential roles in metabolic signaling and cellular regulation. These di- and tricarboxylates are imported into the cell by the divalent anion sodium symporter (DASS) family of plasma membrane transporters, which contains both cotransporters and exchangers. GF120918 While DASS proteins transport substrates via an elevator mechanism, to date structures are only available for a single DASS cotransporter protein in a substrate-bound, inward-facing state. We report multiple cryo-EM and X-ray structures in four different states, including three hitherto unseen states, along with molecular dynamics simulations, of both a cotransporter and an exchanger. Comparison of these outward- and inward-facing structures reveal how the transport domain translates and rotates within the framework of the scaffold domain through the transport cycle. Additionally, we propose that DASS transporters ensure substrate coupling by a charge-compensation mechanism, and by structural changes upon substrate release.The importance of cultural processes to behavioural diversity in our closest living relatives is central to revealing the evolutionary origins of human culture. However, the bonobo is often overlooked as a candidate model. Further, a prominent critique to many examples of proposed animal cultures is premature exclusion of environmental confounds known to shape behavioural phenotypes. We addressed these gaps by investigating variation in prey preference between neighbouring bonobo groups that associate and overlap space use. We find group preference for duiker or anomalure hunting otherwise unexplained by variation in spatial usage, seasonality, or hunting party size, composition, and cohesion. Our findings demonstrate that group-specific behaviours emerge independently of the local ecology, indicating that hunting techniques in bonobos may be culturally transmitted. link2 The tolerant intergroup relations of bonobos offer an ideal context to explore drivers of behavioural phenotypes, the essential investigations for phylogenetic constructs of the evolutionary origins of culture.The evolutionary forces shaping life history divergence within species are largely unknown. Turquoise killifish display differences in lifespan among wild populations, representing an ideal natural experiment in evolution and diversification of life history. By combining genome sequencing and population genetics, we investigate the evolutionary forces shaping lifespan among wild turquoise killifish populations. We generate an improved reference genome assembly and identify genes under positive and purifying selection, as well as those evolving neutrally. Short-lived populations from the outer margin of the species range have small population size and accumulate deleterious mutations in genes significantly enriched in the WNT signaling pathway, neurodegeneration, cancer and the mTOR pathway. We propose that limited population size due to habitat fragmentation and repeated population bottlenecks, by increasing the genome-wide mutation load, exacerbates the effects of mutation accumulation and cumulatively contribute to the short adult lifespan.I think what unites the given poems is a desire to interrogate oppressive language used as an attempt to regulate the power/humanity of or to control women, particularly Black and Brown women, myself included. This speech comes in many forms whether in a reckless and racist tweet we see coming from the current U.S. President, a catcall on the street, a little ole micro-aggressive comment in the workplace, or in the instances taken up by the poems.Nagaland has witnessed violent conflict for over five decades. It is a heavily militarized space where draconian laws like the Armed Forces Special Powers Act allow army personnel to go unchallenged even after committing violent crimes. Few women have used their tradition-specific gendered role strategically to subvert gender norms and exhibit agency against violence within the conflict situation and the systemic violence that bars them from entering the public-political sphere. This article studies how women from the Naga tribal communities use their tradition-specific gender roles of motherhood to gain agency and resist the formation of a hostile, gendered social space.The poems selected here explore the hidden side of some of the most popular fairy tales. Girls become women guided by myths that define their passive role, their submission to violent behavior by men in their lives, be they fathers, husbands, or lovers. These poems look at a girl's fantasies from a different perspective that a woman's life becomes the work of demystifying the myths that dominated her childhood to create a newly informed and subversive version of the myth.This article examines the experience of eight graduate students in the drama therapy program at Lesley University when creating and performing a theater piece centered around gender-based violence. The performance piece, A Space to Speak, used the performers' real-life stories to highlight their vastly different, yet strikingly similar, experiences and invited the audience to examine their own relationship to those stories. A description of the process used to create and perform the piece is followed by a discussion of the impact the process had on the performers and audience members.The #MeToo and Time's Up movements have sparked a significant cultural shift in the United States around sexual harassment and abuse by creating an environment of support, rather than one that punishes and silences women and men who come forward to tell their stories about abuse of all kinds. The Cape Verdean community faces a variety of complex challenges and barriers in addressing intimate partner violence. This article chronicles my experiences reporting the study findings from the Cape Verdean Women's Project (CVWP), which included Cape Verdean women's perceptions of intimate violence and their recommendations for social change.Occupational exposure in spraying and application of non-arsenical insecticides has been classified as a probable human carcinogen. The fundamental molecular mechanisms involved the tumor-related genes. This study aimed to investigate the carcinogenesis effects related to chronic exposure to organophosphate (OP) pesticides in pesticide applicators. This was a cross-sectional study conducted on 27 pesticide applicators and 24 matched controls through the period from June to December 2018. The level of acetylcholinesterase (AChE) was determined and the effects of OPs exposure on messenger RNA (mRNA) expression of the DNA-damage responsive genes P53, P21, GADD45a, and MDM2 were determined using real-time quantitative polymerase chain reaction. A significant reduction of serum AChE enzyme activities was observed in chronically exposed subjects in comparison with the control group (p = 0.001). The expression of P53, P21 mRNA was significantly downregulated in the exposed group compared with the healthy nonexposed control group (p 0.05). No significant differences were noted between the exposed and control groups regarding the genotype or allele distributions of P53 Arg72Pro polymorphism. These results suggested that chronic exposure to OP insecticides may have mitogenic and carcinogenicity activity for the exposed cases due to downregulation of P53 and P21 but did not demonstrate any DNA damage properties for the exposed cases, and finally, a regular follow-up of the exposed cases for tumor markers is recommended.Visceral artery pseudoaneurysms are common complications of pancreatitis that carry a high mortality rate. link3 Early detection and treatment of the pseudoaneurysms should be done as they carry high mortality following rupture. The splenic artery is the commonest artery involved followed by gastroduodenal and pancreaticoduodenal arteries. Gastric artery pseudoaneurysms are less common with less than 50 cases reported in the literature till now. We describe a case of gastric artery pseudoaneurysm secondary to chronic pancreatitis in a patient who presented with intermittent GI bleeding and also describe the role of endovascular management in the treatment of the same.

Endovascular procedures are now the standard of care for endovascular aortic aneurysm repair but treatment of hostile proximal neck anatomy is still challenging. New endografts were brought to the market specifically designed to accommodate severe neck angulation. Authors describe a preliminary experience and early results using the Gore Excluder Conformable endograft (W. L. Gore & Associates, Flagstaff, Ariz) and its active control system in severe neck angulation with a standardized technical approach to achieve precise deployment in this hostile anatomy.

From June 2019 to May 2020, five patients with abdominal aortic aneurysm and severe neck angulation (≥70°) were treated with the Gore Excluder Conformable endograft at two different centers. Deployment of this endograft in this kind of anatomy should be aggressive starting over the level of renal arteries due to risk of distal migration downward on the external curvature and difficulty in upward repositioning. Authors suggested a standard techniqueies possibly affecting early outcomes.

Routine use of through-and-through axillary-femoral guidewire associated with selective pre-cannulation of the lower renal artery allows a precise deployment of the Gore Excluder Conformable endograft in difficult anatomies possibly affecting early outcomes.The case refers to a 51-year-old symptomatic man with a new SARS-CoV-2 RNA positive nasopharyngeal swab after two negative ones and the lack of significant development of antibody response measured by different diagnostic serological test. Our case underlines that a discrepancy between clinical course of SARS-CoV-2 infection and results from diagnostic tests may exist. This concept is rapidly emerging and supports the need for a deep knowledge of available and "in development" tests for a correct interpretation of their findings.
