Dorcas Hager Padget was a renowned neurosurgical illustrator and neuroembryologist. She collaborated closely with Walter E. Dandy, founder of the field of vascular neurosurgery, from 1928 until his death in 1946.

Nonheme Mononuclear and Dinuclear Iron(II) and Iron(III) Fluoride Complexes and Their Fluorine Radical Transfer Reactivity.

The nonheme iron(II) complexes containing a fluoride anion, Fe(BNPAO)(F) () and [Fe(BNPAOH)(F)(THF)](BF) (), were synthesized and structurally characterized. Addition of dioxygen to either or led to the formation of a fluoride-bridged, dinuclear iron(III) complex [Fe(BNPAO)(F)(μ-F)] (), which was characterized by single-crystal X-ray diffraction, H NMR, and elemental analysis. An iron(II)(iodide) complex, Fe(BNPAO)(I) (), was prepared and reacted with O to give the mononuclear complex -Fe(BNPAO)(OH)(I) ().

Rapid Weight Gain After Pediatric Kidney Transplant and Development of Cardiometabolic Risk Factors Among Children Enrolled in the North American Pediatric Renal Trials and Collaborative Studies Cohort.

Introduction: Given the risks of cardiovascular disease among pediatric kidney transplant recipients, we evaluated whether there was an association between rapid weight gain (RWG) following kidney transplantation and the development of obesity and hypertension among children enrolled in the North American Pediatric Renal Trials and Collaborative Studies (NAPRTCS) registry.

Methods: This retrospective analysis of the NAPRTCS transplant cohort assessed for RWG in the first year post-transplant and evaluated for obesity and hypertension in children with and without RWG up to 5 years post-transplant. We evaluated three separate eras (1986-1999, 2000-2009, and 2010-2021).

Shared Decision-Making in Total Hip and Knee Arthroplasty: Understanding Surgeon and Patient Perspectives Regarding When It Is Time for Surgery.

Background: Although total hip and total knee arthroplasty are highly successful operations, the decision of whether and when to undergo surgery is highly subjective and discretionary, and specific guidelines regarding readiness for surgery remain elusive. The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.

Transcriptomic resources for Bagrada hilaris (Burmeister), a widespread invasive pest of Brassicales.

The bagrada bug, Bagrada hilaris (Burmeister), is an emerging agricultural pest in the Americas, threatening agricultural production in the southwestern United States, Mexico and Chile, as well as in the Old World (including Africa, South Asia and, more recently, Mediterranean areas of Europe). Substantive transcriptomic sequence resources for this damaging species would be beneficial towards understanding its capacity for developing insecticide resistance, identifying viruses that may be present throughout its population and identifying genes differentially expressed across life stages that could be exploited for biomolecular pesticide formulations. This study establishes B.

A randomized controlled trial on anonymizing reviewers to each other in peer review discussions.

Many peer-review processes involve reviewers submitting their independent reviews, followed by a discussion between the reviewers of each paper. A common question among policymakers is whether the reviewers of a paper should be anonymous to each other during the discussion. We shed light on this question by conducting a randomized controlled trial at the Conference on Uncertainty in Artificial Intelligence (UAI) 2022 conference where reviewer discussions were conducted over a typed forum.

Application of Causal Forest Model to Examine Treatment Effect Heterogeneity in Substance Use Disorder Psychosocial Treatments.

Methods: Data from 12 randomized controlled trials of nine psychosocial treatments were obtained from the National Institute on Drug Abuse Clinical Trials Network.

School and meal characteristics associated with plate waste in K-12 cafeterias in the United States.

Food wasted in primary and secondary education institutions creates nutritional losses, financial inefficiencies, and environmental degradation. While there is some evidence of how particular interventions within schools may influence the amount of waste created, there is little recent information about typical levels of food waste generated in U.S.

Detection of Putative Ligand Dissociation Pathways in Proteins Using Site-Identification by Ligand Competitive Saturation.

Drug efficacy often correlates better with dissociation kinetics than binding affinity alone. To study binding kinetics computationally, it is necessary to identify all of the possible ligand dissociation pathways. The site identification by ligand competitive saturation (SILCS) method involves the precomputation of a set of maps (FragMaps), which describe the free energy landscapes of typical chemical functionalities in and around a target protein or RNA.

Memristive Ion Dynamics to Enable Biorealistic Computing.

Conventional artificial intelligence (AI) systems are facing bottlenecks due to the fundamental mismatches between AI models, which rely on parallel, in-memory, and dynamic computation, and traditional transistors, which have been designed and optimized for sequential logic operations. This calls for the development of novel computing units beyond transistors. Inspired by the high efficiency and adaptability of biological neural networks, computing systems mimicking the capabilities of biological structures are gaining more attention.

Prevalence of Disability Among Older Adults in Prison.

Importance: The number of older adults in long-term correctional facilities (prisons) has increased rapidly in recent years. The cognitive and functional status of this population is not well understood due to limitations in the availability of longitudinal data.

Objective: To comparatively examine the prevalence and disability status of the population of adults 55 years and older in prisons and adults living in community settings for a 14-year period (2008-2022).

Mild Gestational Hypothyroidism in Mice Has Transient Developmental Effects and Long-Term Consequences on Neuroendocrine Systems.

Thyroid hormones (TH) play a key role in fetal brain development. While severe thyroid dysfunction, has been shown to cause neurodevelopmental and reproductive disorders, the rising levels of TH-disruptors in the environment in the past few decades have increased the need to assess effects of subclinical (mild) TH insufficiency during gestation. Since embryos do not produce their own TH before mid-gestation, early development processes rely on maternal production.

Modulation of the Plasma Lipidomic Profile in Piglets Fed Polar Lipid-Rich Diets.

Polar lipids from dairy are novel sources of energy that may replace other dietary lipids and impact plasma lipidomic profiles in piglets. This study evaluated the impact of feeding diets rich in polar lipids on the plasma lipidome of piglets during the weaning period. Weaned male piglets ( = 240; 21 days of age; 6.

radiosensitivity and Mn antioxidant content: antigenic preservation and pathobiology.

The bacterium responsible for Lyme disease, , accumulates high levels of manganese without iron and possesses a polyploid genome, characteristics suggesting potential extreme resistance to radiation. Contrary to expectations, we report that wild-type B31 cells are radiosensitive, with a gamma-radiation survival limit for 10 wild-type cells of <1 kGy. Thus, we explored radiosensitivity through electron paramagnetic resonance (EPR) spectroscopy by quantitating the fraction of Mn present as antioxidant Mn metabolite complexes (H-Mn).

HIV-1 transcription start sites usage and its impact on unspliced RNA functions in people living with HIV.

HIV-1 unspliced RNA serves two distinct functions during viral replication: it is packaged into particles as the viral genome, and it is translated to generate Gag/Gag-Pol polyproteins required for virus assembly. Recent studies have demonstrated that in cultured cells, HIV-1 uses multiple transcription start sites to generate several unspliced RNA species, including two major transcripts with three and one 5' guanosine, referred to as 3G and 1G RNA, respectively. Although nearly identical, 1G RNA is selected over 3G RNA to be packaged as the virion genome, indicating that these RNA species are functionally distinct.

Integrating Implementation Science in Interpersonal Violence Research and Practice: A Systematic Review of Barriers and Facilitators of Implementation.

Despite the prevalence and harmful consequences of interpersonal violence and the growth in intervention research, applying research evidence and strategies into practice remains limited. This systematic review addresses this gap by using the Consolidated Framework of Implementation Research (CFIR) to characterize barriers and facilitators in efforts to prevent and address interpersonal violence. A systematic search of peer-reviewed literature was conducted using the following databases: PubMed, Embase, CINAHL, Cochrane, Web of Science, Scopus, and APA PsycInfo.

The Unusual Role of Ribonuclease L in Innate Immunity.

Ribonuclease L is an endonuclease that is activated as part of the dsRNA-driven innate immune response. Active RNase L cleaves pathogenic RNAs as a way to eliminate infections. However, there are additional and unexpected ways that RNase L causes changes in the host that promote an immune response and contribute to its role in host defense.

Pilot Study: Human Adipose Tissue Allograft for Fat Pad Defects in Patients With Preulcerative Lesions.

Background: Loss or displacement of a fat pad on the foot increases plantar pressure, leading to pain and plantar ulcers. These ulcers, especially in patients with diabetic neuropathy, have high recurrence rates, often resulting in amputations. Standard of care focuses on reducing plantar pressure with shoe padding or orthotic devices, leaving the restoration of the fat pad as an unmet medical need.
