T cell acute lymphoblastic leukemia (T-ALL) is an aggressive immature T cell cancer. Mutations in IL7R have been analyzed genetically, but downstream effector functions such as STAT5A and STAT5B hyperactivation are poorly understood. Here, we studied the most frequent and clinically challenging STAT5BN642H driver in T cell development and immature T cell cancer onset and compared it with STAT5A hyperactive variants in transgenic mice. Enhanced STAT5 activity caused disrupted T cell development and promoted an early T cell progenitor-ALL phenotype, with upregulation of genes involved in T cell receptor (TCR) signaling, even in absence of surface TCR...

Firearm violence is a pressing public health issue in the United States and becoming increasingly so worldwide. This concern has prompted researchers to examine the prevalence of such violence in media entertainment. Japanese manga have a large youth readership in the U.S., yet research on their depictions of firearms is presently lacking. We randomly selected 50 chapters from each of ten top-selling manga series worldwide ( N = 500) to identify dialogue, action, and other illustrations involving handguns, rifles, machine guns, other projectile weapons, and bombs...

Firearm carriage and possession predicts youth firearm violence victimization and perpetration. This study describes self-reported factors associated with firearm access, carriage, and possession among justice-involved youth. We conducted an exploratory, mixed-methods study. Participants were recruited from May 2022 to February 2023 from the Juvenile Justice Collaborative, a diversion program for justice-involved youth. We used online anonymous surveys to investigate exposures related to firearm access, carriage, and possession...

Features of threatening cues and the associated context influence the perceived imminence of threat and the defensive responses evoked. To provide additional knowledge about how the directionality of a threat (i.e. directed-towards or away from the viewer) might impact defensive responses in humans, participants were shown pictures of a man carrying a gun (threat) or nonlethal object (neutral) directed-away from or towards the participant. Cardiac and electrodermal responses were collected. Compared to neutral images, threatening images depicting a gun directed-towards the participant induced sustained bradycardia and an increased electrodermal response, interpreted as immobility under attack...

This study explores the combined potential of severe plastic deformation (SPD) via differential speed rolling (DSR) and plasma electrolytic oxidation (PEO) to enhance the material performance of 6061 Al alloys. To this end, DSR was carried out at a roll-speed-ratio of 1:4 to obtain ~75% total thickness reduction and a final microstructure of <1 µm. The rest of the samples were annealed to obtain various grain sizes of ~1, ~25, and ~55 μm. Through DSR, the hardness of the material increased from ~64 to ~102 HV...

INTRODUCTION: Understanding gun owners' perceptions of potential firearm policies' harms and benefits is critical to successful policy development and implementation. We used national survey data to develop and validate a novel instrument, the Harms and Benefits Inventory (HBI), for policy-makers and advocates to better consider the citizen perspective. METHOD: We conducted a nationally representative survey of American gun owners and non-owners (N=2007) using the Social Science Research Solutions probability panel...

After every school shooting in the United States both a wish and a fear arise: Will this be the one? Will this be the tipping point for change in a nation so deeply divided over the meaning of "the right to bear arms?" Sandy Hook, Connecticut? No. Parkland, Florida? No. So, why might the killing of 19 children and 2 teachers in Uvalde, Texas, prove different? The American epidemic of mass school shootings betrays a country's willingness to let its children disappear, to sacrifice them on the altar of an archetypally violent ethos...

BACKGROUND: The management of branch-duct type intraductal papillary mucinous neoplasms (BD-IPMN) varies in existing guidelines. This study investigated the optimal surveillance protocol and safe discontinuation of surveillance considering natural history in non-resected IPMN, by systematically reviewing the published literature. METHODS: This review was guided by PRISMA. Research questions were framed in PICO format "CQ1-1: Is size criteria helpful to determine surveillance period? CQ1-2: How often should surveillance be carried out? CQ1-3: When should surveillance be discontinued? CQ1-4: Is nomogram predicting malignancy useful during surveillance?"...

IMPORTANCE: American Indian or Alaska Native and Black adults experience elevated rates of firearm injury and death, but both groups are severely underrepresented in research on firearm exposure and behaviors. OBJECTIVE: To explore geodemographic differences in firearm behaviors and violence exposure among American Indian or Alaska Native and Black adults in the US. DESIGN, SETTING, AND PARTICIPANTS: In this survey study, nationally representative samples of American Indian or Alaska Native and/or Black adults recruited from KnowledgePanel were surveyed cross-sectionally...

Suicide attempts and school violence, including gun violence, are now leading causes of death in youth 12-17. This study applied a latent class analytic approach to investigate how heterogenous subgroups of youth differed regarding patterns of violence engagement and suicide risk behavior and how geographic, demographic, and socioeconomic predictors related to subgroup membership. Data were drawn from the youth subsample of the 2021 National Survey on Drug Use and Health (N = 10,743). A suicide risk subgroup had low probabilities of violence engagement but high probabilities of suicide ideation and plan...

BACKGROUND: Recent data show high school students from racial and ethnic minority (REM) backgrounds in the United States confront a twofold challenge, marked by the highest rates of firearm-related homicides since 1994 and increased youth substance use. The pandemic increased online and telehealth usage opportunities for at-risk REM youth. Therefore, this study investigated (1) the frequency and prevalence of co-occurring youth violence and substance use among REM adolescents, (2) racial/ethnic, age, and natal sex (as gender data was not collected) differences in patterns and trends in co-occurring youth violence and substance use among REM adolescents, and (3) the relationship between these syndemic issues and REM adolescent mental telehealth use during the pandemic...

Although studies have investigated and found an association between victimization and weapon carrying, few studies have examined the association between exposure to neighborhood violence (NV) and gun carrying among adolescents. The objective of this study was to examine the cross-sectional association between exposure to NV and gun carrying among adolescents. Data for this study came from the 2021 Youth Risk Behavior Survey. An analytic sample of 17,033 adolescents aged 14 to 18 years old (51.7% male) was analyzed using logistic regression with complementary log-log link function...

The bacterial enzyme chondroitinase ABCI (chABCI), which has been isolated from Proteus Vulgaris, is crucial in the treatment of spinal cord injuries. However, due to its short lifespan, the maintenance and clinical application of this enzyme are very constrained. In this study, the immobilization of this enzyme on hydroxyapatite has been carried out and assessed with the aim of enhancing the characteristics and efficiency of chABCI. Hydroxyapatite particles (HAPs) are a potential candidate for drug-delivery carriers because of their excellent biocompatibility, shape controllability, and high adsorption...

This Article examines how the rapid deregulation and rampant possession of firearms is likely going to impact policing, and the constitutional law that governs it. For the longest time, lawful gun carry, concealed or open, was exceedingly rare. For a police officer to see a gun was both to see danger, and a crime in progress. This link among guns, danger, and unlawful possession has shaped much of the law of policing. But now, this understanding of the world is in its last stages of unraveling. In nearly all states, guns are no longer unlawful to own and carry by default...

Access to firearms among individuals with mental health problems has been a source of protracted debate among policymakers, the media, and the public, writ large. At the center of this controversy are questions about the nature and consequences of gun access in the context of mental illness. The lack of substantial empirical evidence, due in part to limited access to quality data, plays a significant role in perpetuating ongoing debate. To address this problem, this study uses data from the National Comorbidity Survey Replication to evaluate the relative importance of several clinical, cultural, and criminological factors in explaining gun access and carrying among adults with and without mental illnesses...

OBJECTIVE: Trainees or medical residents' experiences of hospital rotations and training have not been sufficiently studied. More empirical holistic studies of experiences of General Practice/Family Medicine (GP/FM) residents in Sweden are needed. The purpose of this study was to describe experiences of hospital rotation during residency. DESIGN: Empirical-holistic study. SETTING: GP/FM residents were invited by email to participate in the study...

The β-tubulin ( benA ) gene is a promising target for the identification of Aspergillus species. Assessment of the clinical implementation and performance of benA gene-based Aspergillus polymerase chain reaction (PCR) remains warranted. In this study, we assessed the analytical performance of the BenA probe PCR in comparison with the Aspergenius kit. We prospectively collected bronchoalveolar lavage (BAL) fluid via diagnostic bronchoscopy from adult patients with hematologic diseases. BenA gene-based multiplex real-time PCR and sequential melting temperature analysis were performed to detect the azole resistance of Aspergillus fumigatus ...

The use of non-lethal weapons has spread worldwide, being introduced as an alternative to firearms in many countries such as the United States or the United Kingdom. Among non-lethal weapons, conducted electrical weapons have been adopted worldwide, to control unruly suspected criminals or to neutralise violent situations. The stun gun belongs to this category and is the most widely available, with more than 140,000 units in use by police officers in the field in the US, and an additional 100,000 electrical stun guns owned by civilians worldwide...
