We previously reported that hydroxylated oxime ether lipids (OELs) efficiently deliver functional Dicer substrate siRNAs (DsiRNAs) in cells. Here, we explored in vivo utility of these OELs, using OEL4 as a prototype and report that surface modification of the OEL4 formulations was essential for their in vivo applications. These surface-modified OEL4 formulations were developed by inclusion of various PEGylated lipids.

Lipid-based formulations provide a nanotechnology platform that is widely used in a variety of biomedical applications because it has several advantageous properties including biocompatibility, reduced toxicity, relative ease of surface modifications, and the possibility for efficient loading of drugs, biologics, and nanoparticles. A combination of lipid-based formulations with magnetic nanoparticles such as iron oxide was shown to be highly advantageous in a growing number of applications including magnet-mediated drug delivery and image-guided therapy. Currently, lipid-based formulations are prepared by multistep protocols.

is a Gram-negative alphaproteobacterium that commonly lives in oligotrophic fresh- and saltwater environments. is a host to many bacteriophages, including ϕCbK and ϕCbK-like bacteriophages, which require interaction with the bacterial flagellum and pilus complexes during adsorption. It is commonly thought that the six paralogs of the flagellin gene present in are important for bacteriophage evasion.

"Reclaim the W" is an academic recovery program at a medium-sized midwestern university that offers undergraduates who have been academically dismissed a chance to reenroll at the institution. In this article we describe the Reclaim the W program and its target population of academically at-risk undergraduates. We then outline the first two phases of the process we used to develop an intervention for students in the Reclaim the W program, which we call Engage to Excel (E).

Among youth who commit sexual crimes, childhood trauma experiences have been linked to a host of outcomes including trauma symptom expression. Furthermore, research has begun assessing differential rates of cumulative adverse childhood experiences (ACEs) between youth who commit sexual and non-sexual crimes. Yet, few studies have comparatively examined rates of cumulative traumatic events using more robust measures of adversity.

Objective: Court diversion programs offer alternative treatment interventions in lieu of punitive sanctions. Programs have recently been developed for women arrested for prostitution, with a recognition that many of these individuals frequently experience multiple forms of violence and experience multiple barriers to exiting sex work. This review aims to (a) examine programmatic components used across programs, and (b) identify the diversionary programs' impact on participants.

Background: Increasingly, studies have focused on understanding positive outcomes in children who have been maltreated and the factors that contribute to resilience. However, there is no universally accepted definition of resilience, thus hindering the ability to make comparisons across studies and to use such information to inform interventions to foster resilience.

Objective: The current study sought to address this gap by examining definitions of resilience in practitioners who work directly with maltreated children.

Objectives: The aims of the study were to examine the reactions of first-year health profession students to medical errors and determine whether differences exist between disciplines.

Methods: After viewing the Team STEPPS Program's Susan Sheridan video that describes two separate medical errors, students from anesthesia assistant, medical imaging, medicine, nursing, physical therapy, and physician assistant programs provided unstructured open responses reflecting on initial impressions of medical errors depicted in the film. Student responses were assessed via inductive coding techniques and thematic analysis and stratified by discipline.

There is limited research examining the association between child maltreatment and cigarette smoking as a specific type of adolescent substance use, and research examining high-risk samples and variations based on maltreatment type and timing remain sparse. The primary aim of the study was to examine the relationship between child maltreatment and cigarette smoking trajectories. Latent class growth analysis and multinomial logistic regression were performed on 903 youth drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN).

African swine fever virus (ASFV) is a complex nucleocytoplasmic large DNA virus (NCLDV) that causes a devastating swine disease currently present in many countries of Africa, Europe, and Asia. Despite intense research efforts, relevant gaps in the architecture of the infectious virus particle remain. Here, we used single-particle cryo-EM to analyze the three-dimensional structure of the mature ASFV particle.

Resilience following childhood maltreatment has received substantial empirical attention, with the number of studies on this construct growing exponentially in the past decade. While there is ample interest, inconsistencies remain about how to conceptualize and assess resilience. Further, there is a lack of consensus on how developmental stage influences resilience and how protective factors affect its expression.

The current study investigates the role of race and county characteristics in substantiation and out-of-home placement decisions in the United States. Using multilevel models, we analyzed data from counties in the United States available through the National Child Abuse and Neglect Data Systems and Adoption and Foster Care Analysis and Reporting System to investigate the interactions between children's race and the context in which they live. Our sample consisted exclusively of children whose cases had been investigated; therefore, we were able to focus on the role played by race and county characteristics in substantiation and out-of-home placement decisions made by Child Protective Services, net of the heightened risk factors (or potential biases) that lead to disparate rates of reporting.

While recent research has established the abuse and victimization histories of youth who engage in sexually abusive behavior, there is still debate regarding the significance of trauma and abuse as developmental antecedents to sexual offending in adolescence. Moreover, research has not conclusively identified the types, context, and timing of adverse experiences that act as catalysts for subsequent sexual perpetration. The present comprehensive literature review has one primary aim: Explore the adverse childhood experiences of youth who engage in sexually abusive behavior, considering whether trauma may be a consistent developmental antecedent to offending.

Background: Developing a Research Participation Enhancement and Advocacy Training Program for Diverse Seniors (DREAMS) is a two-part health education (part 1 [DP1]) and research advocacy training (part 2 [DP2]) program grounded in CBPR principles designed to address underrepresentation of socioeconomically disadvantaged and/or minority older adults in research.

Objectives: We examine the effects of DREAMS on health literacy, psychosocial function, beliefs/attitudes toward research, and self-efficacy in diverse older adults age 65 and older who completed only part 1 of DREAMS (n = 51) versus those who completed both parts 1 and 2 (DREAMS Team [DT]; n = 24). We hypothesized that benefits would be observed in both groups, with greater benefits seen among DT completers versus those who completed only part 1.

There is a strong theoretical and research base demonstrating the link between attachment styles and adolescent sexual offending. However, this relationship may be best explained by deficit-based mediational pathways including criminogenic needs such as emotional or affect regulation and callousness. Grady, Levenson, and Bolder propose a framework that details criminogenic needs as intermediary variables in the attachment-sexual offending relationship.

Background: The majority of youth with problem sexualized behaviors (PSB) have substantiated experiences of abuse or exposures to violence (Silovsky & Niec, 2002). Little is known about specific abuse experiences that may differentiate youth with PSB from those without. Few studies have examined the types of abuse associated with post-traumatic stress symptomology.

Grady, Levenson, and Bolder's etiological framework contextualizes sexual offending behaviors through a trauma and attachment lens to suggest child abuse experiences (CAE) are associated with attachment problems that contribute to sexual offending. To empirically test a portion of this theory, this cross-sectional study employed a structural equation mediated-moderated model on a sample of juvenile justice-involved youth ( = 505) who committed sexual ( = 355) and non-sexual ( = 150) offenses. Results revealed a good model fit and statistically significant direct effects between maternal harsh and indifferent caregiving styles and insecure attachment.

Measles virus (MeV) remains a major human pathogen, but there are presently no licensed antivirals to treat MeV or other paramyxoviruses. Here, we use cryo-electron tomography (cryo-ET) to elucidate the principles governing paramyxovirus assembly in MeV-infected human cells. The three-dimensional (3D) arrangement of the MeV structural proteins including the surface glycoproteins (F and H), matrix protein (M), and the ribonucleoprotein complex (RNP) are characterized at stages of virus assembly and budding, and in released virus particles.
