Diverse organic-mineral associations in Jezero crater, Mars.

The presence and distribution of preserved organic matter on the surface of Mars can provide key information about the Martian carbon cycle and the potential of the planet to host life throughout its history. Several types of organic molecules have been previously detected in Martian meteorites1 and at Gale crater, Mars2-4. Evaluating the diversity and detectability of organic matter elsewhere on Mars is important for understanding the extent and diversity of Martian surface processes and the potential availability of carbon sources1,5,6. Here we report the detection of Raman and fluorescence spectra consistent with several species of aromatic organic molecules in the Máaz and Séítah formations within the Crater Floor sequences of Jezero crater, Mars. We report specific fluorescence-mineral associations consistent with many classes of organic molecules occurring in different spatial patterns within these compositionally distinct formations, potentially indicating different fates of carbon across environments. Our findings suggest there may be a diversity of aromatic molecules prevalent on the Martian surface, and these materials persist despite exposure to surface conditions. These potential organic molecules are largely found within minerals linked to aqueous processes, indicating that these processes may have had a key role in organic synthesis, transport or preservation.

Selective Ablation of Sod2 in Astrocytes Induces Sex-Specific Effects on Cognitive Function, d-Serine Availability, and Astrogliosis.

Cognitive decline is a debilitating aspect of aging and neurodegenerative diseases such as Alzheimer's disease are closely associated with mitochondrial dysfunction, increased reactive oxygen species, neuroinflammation, and astrogliosis. This study investigated the effects of decreased mitochondrial antioxidant response specifically in astrocytes on cognitive performance and neuronal function in C57BL/6J mice using a tamoxifen-inducible astrocyte-specific knockout of manganese superoxide dismutase (aSOD2-KO), a mitochondrial matrix antioxidant that detoxifies superoxide generated during mitochondrial respiration. We reduced astrocyte SOD2 levels in male and female mice at 11-12 months of age and tested in an automated home cage (PhenoTyper) apparatus for diurnal patterns, spatial learning, and memory function at 15 months of age. aSOD2-KO impaired hippocampal-dependent spatial working memory and decreased cognitive flexibility in the reversal phase of the testing paradigm in males. Female aSOD2-KO showed no learning and memory deficits compared with age-matched controls despite significant reduction in hippocampal SOD2 expression. aSOD2-KO males further showed decreased hippocampal long-term potentiation, but paired-pulse facilitation was unaffected. Levels of d-serine, an NMDA receptor coagonist, were also reduced in aSOD2-KO mice, but female knockouts showed a compensatory increase in serine racemase expression. Furthermore, aSOD2-KO mice demonstrated increased density of astrocytes, indicative of astrogliosis, in the hippocampus compared with age-matched controls. These data demonstrate that reduction in mitochondrial antioxidant stress response in astrocytes recapitulates age-related deficits in cognitive function, d-serine availability, and astrogliosis. Therefore, improving astrocyte mitochondrial homeostasis may provide a therapeutic target for intervention for cognitive impairment in aging.SIGNIFICANCE STATEMENT Diminished antioxidant response is associated with increased astrogliosis in aging and in Alzheimer's disease. Manganese superoxide dismutase (SOD2) is an antioxidant in the mitochondrial matrix that detoxifies superoxide and maintains mitochondrial homeostasis. We show that astrocytic ablation of SOD2 impairs hippocampal-dependent plasticity in spatial working memory, reduces long-term potentiation of hippocampal neurons and levels of the neuromodulator d-serine, and increases astrogliosis, consistent with defects in advanced aging and Alzheimer's disease. Our data provide strong evidence for sex-specific effects of astrocytic SOD2 functions in age-related cognitive dysfunction.

Therapy service delivery for children with disabilities during COVID-19: Parent perceptions and implementation recommendations.

This study identifies challenges and advantages parents faced in navigating therapy service delivery for their child with disabilities during the COVID-19 pandemic. As part of an online survey, 171 parents of children with disabilities answered four, free response questions regarding the therapy services their children received during the pandemic. A grounded theory approach was used to identify top challenges, barriers, advantages, and recommendations. Challenges included children's poor response to telehealth services, lack of parent training, and technological challenges. Advantages included fewer barriers to service access and increased family involvement. Parents largely recommended shorter, more frequent teletherapy sessions, and resuming in-person services. To improve parent engagement in, and the sustainability of, services, parent feedback should inform service delivery design and implementation. Incorporating parent feedback about service delivery can decrease disparities in access and increase parent engagement in child services both generally, and during periods of service disruption.

Characterization of microplastics in indoor and ambient air in northern New Jersey.

Airborne microplastics (MPs) could have negative impacts on human health and pollute water, soil, and sediment. This study explored the distributions, compositions, and morphology of airborne microplastics in the indoor and ambient air in New Jersey, United States. Microplastic fibers, films, and fragments of Polystyrene (PS), Polyethylene terephthalate (PET), Polyethyelene (PE), Polyvinyl chloride (PVC) and Polypropylene (PP) were identified in office, hallway, classroom, and single-family house in this study. The deposition rates of synthetic fibers with length from 35 µm to 1000 µm were highest in the single-family house ((1.96 ± 1.09) × 104 fibers/m2/day) and lowest in the classroom ((6.20 ± 0.57) × 103 fibers/m2/day), suggesting that residential houses are a major source of microplastic fibers. However, for film-like plastics with surface areas ranging from 200 µm2 to 5000 µm2, a high deposition rate of (8.13 ± 2.17) × 103 films/m2/day was observed in the classroom, whereas the lowest deposition rate of (4.45 ± 0.27) × 103 films/m2/day was found in the hallway, probably because plastic films such as PE are intensively used in the classroom environments. The deposition rate of microplastics in the ambient air acquired on a building roof was only about 2-8% of the indoor deposition rates. The microplastics with similar textures but different sizes were identified in both total atmospheric deposition and particulate samples (PM2.5 and PM10), suggesting degradation from microplastics to nanoplastics. The main microplastics found in indoor air samples were PE fragments or fibers, different from those in the outdoor ambient air that were dominated by PVC fragments. These results unravel the properties of airborne microplastics in urban environments that are important to understanding their fate, transport, and potential health risks.

The Impact of the Novel Coronavirus Disease 2019 on Therapy Service Delivery for Children with Disabilities.

OBJECTIVE: To assess the impact of the novel coronavirus disease 2019 (COVID-19) pandemic on the delivery of, and parent satisfaction with, therapy services for children with disabilities in early intervention, school, and outpatient settings. STUDY DESIGN: There were 207 parents of children with disabilities who completed a web-based survey about their child[ren]'s access to, and satisfaction with, therapy services during COVID-19. Parents also completed the Family-Provider Partnership Scale and the Telehealth Satisfaction Scale. Satisfaction was compared between families receiving therapies in school, early intervention, outpatient, and multiple settings. RESULTS: Forty-four percent of parents reported low satisfaction with their child[ren]'s therapy services during the pandemic. Access to telehealth positively predicted overall satisfaction and satisfaction with the family-provider partnership, whereas receiving school-based therapies negatively predicted overall satisfaction and satisfaction with the family-provider partnership. CONCLUSIONS: School-based therapies are legally mandated for eligible students, free of cost to families, integrated in the academic setting, and less burdensome on parents than other services. Thus, given the disparity in parental satisfaction regarding school-based service delivery, addressing therapy delivery in school-based settings during the duration of COVID-19 is critical for preventing increased disparities and more effectively meeting children's needs. Telehealth seems to be a promising option for continuing high-quality services during the duration of the COVID-19 pandemic and for families who face barriers in accessing services in general. Future studies are warranted with larger and more diverse samples, as well as longitudinal studies that monitor service access and parent satisfaction throughout the remainder of the pandemic.

Influenza Vaccinations During the COVID-19 Pandemic - 11 U.S. Jurisdictions, September-December 2020.

Influenza causes considerable morbidity and mortality in the United States. Between 2010 and 2020, an estimated 9-41 million cases resulted in 140,000-710,000 hospitalizations and 12,000-52,000 deaths annually (1). As the United States enters the 2021-22 influenza season, the potential impact of influenza illnesses is of concern given that influenza season will again coincide with the ongoing COVID-19 pandemic, which could further strain overburdened health care systems. The Advisory Committee on Immunization Practices (ACIP) recommends routine annual influenza vaccination for the 2021-22 influenza season for all persons aged ≥6 months who have no contraindications (2). To assess the potential impact of the COVID-19 pandemic on influenza vaccination coverage, the percentage change between administration of at least 1 dose of influenza vaccine during September-December 2020 was compared with the average administered in the corresponding periods in 2018 and 2019. The data analyzed were reported from 11 U.S. jurisdictions with high-performing state immunization information systems.* Overall, influenza vaccine administration was 9.0% higher in 2020 compared with the average in 2018 and 2019, combined. However, in 2020, the number of influenza vaccine doses administered to children aged 6-23 months and children aged 2-4 years, was 13.9% and 11.9% lower, respectively than the average for each age group in 2018 and 2019. Strategic efforts are needed to ensure high influenza vaccination coverage among all age groups, especially children aged 6 months-4 years who are not yet eligible to receive a COVID-19 vaccine. Administration of influenza vaccine and a COVID-19 vaccine among eligible populations is especially important to reduce the potential strain that influenza and COVID-19 cases could place on health care systems already overburdened by COVID-19.

Bias and sensitivity to task constraints in spontaneous relational attention.

Two experiments examined factors that predicted children's tendencies to match objects versus relations across scenes when no instruction was given. Specifically, we assessed the presence of higher relational responding in children by (a) age, (b) greater presumed experience in generating relations through socialization in China versus the United States, and (c) in children with greater manipulated experience via a relational priming task. Experiment 1 showed that Chinese and U.S. children across all ages showed an initial bias to match objects versus relations across scenes. However, older children in both regions were more likely to notice features of the task that indicated attending to relational matches was a more reliable solution, and shifted their responding toward relations over the course of the task. Experiment 2 replicated the object-mapping bias and age effects within U.S. children while also examining the impact of directly manipulating children's relational experiences to test the malleability of the bias. Before the main scene-mapping task, children did a relation generation task known to prime attention to relations. This did not override the initial bias toward object mapping, but it magnified the role of age, making older children increasingly sensitive to task features that prompted relational matches, further shifting their responding toward relations over the course of the task.

Loss of mitochondrial protease ClpP protects mice from diet-induced obesity and insulin resistance.

Caseinolytic peptidase P (ClpP) is a mammalian quality control protease that is proposed to play an important role in the initiation of the mitochondrial unfolded protein response (UPRmt), a retrograde signaling response that helps to maintain mitochondrial protein homeostasis. Mitochondrial dysfunction is associated with the development of metabolic disorders, and to understand the effect of a defective UPRmt on metabolism, ClpP knockout (ClpP-/-) mice were analyzed. ClpP-/- mice fed ad libitum have reduced adiposity and paradoxically improved insulin sensitivity. Absence of ClpP increased whole-body energy expenditure and markers of mitochondrial biogenesis are selectively up-regulated in the white adipose tissue (WAT) of ClpP-/- mice. When challenged with a metabolic stress such as high-fat diet, despite similar caloric intake, ClpP-/- mice are protected from diet-induced obesity, glucose intolerance, insulin resistance, and hepatic steatosis. Our results show that absence of ClpP triggers compensatory responses in mice and suggest that ClpP might be dispensable for mammalian UPRmt initiation. Thus, we made an unexpected finding that deficiency of ClpP in mice is metabolically beneficial.

Impacts of early social experience on cognitive development in infant rhesus macaques.

Although much is known about the influences of early life experiences on the neurobiology and behavior of macaque models of child development, there is scant literature on cognitive development with respect to early rearing. Here, we examined the effects of rearing condition on affective reactivity and cognitive development in infant rhesus macaques. Infants were pseudo-randomly assigned to one of the two rearing conditions: nursery reared (NR, N = 32; 16 peer-reared, 16 surrogate-peer-reared) or mother-peer-reared (MPR, N = 7). During the first month of life, infants were administered the Primate Neonatal Neurobehavioral Assessment (PNNA). Beginning at 4 months old, infants were tested on cognitive tasks that assessed reward association, cognitive flexibility, and impulsivity. We found no gross cognitive differences between MPR and NR infants. However, MPR infants were more reactive than NR infants on the PNNA. Additionally, reactivity on the PNNA correlated with impulsivity, such that infants who were more reactive at 1 month of age completed fewer trials correctly on this task at 8-10 months. These findings are the first to directly compare cognitive development in MPR and NR infants, and add to the existing literature elucidating the influences of early social experience on temperament and development.

Differential effects of adolescent and adult-initiated exercise on cognition and hippocampal neurogenesis.

Adolescence is a critical period for postnatal brain maturation and thus a time when environmental influences may affect cognitive processes in later life. Exercise during adulthood has been shown to increase hippocampal neurogenesis and enhance cognition. However, the impact of exercise initiated in adolescence on the brain and behavior in adulthood is not fully understood. The aim of this study was to compare the impact of voluntary exercise that is initiated during adolescence or early adulthood on cognitive performance in hippocampal-dependent and -independent processes using both object-based and touchscreen operant paradigms. Adult (8 week) and adolescent (4 week) male Sprague-Dawley rats had access to a running wheel (exercise) or were left undisturbed (sedentary control) for 4 weeks prior to behavioral testing and for the duration of the experiment. Results from touchscreen-based tasks showed that reversal learning was enhanced by both adult and adolescent-initiated exercise, while only exercise that began in adolescence induced a subtle but transient increase in performance on a location discrimination task. Spontaneous alternation in the Y-maze was impaired following adolescent onset exercise, while object memory was unaffected by either adult or adolescent-initiated exercise. Adolescent-initiated exercise increased the number of hippocampal DCX cells, an indicator of neurogenesis. It also promoted the complexity of neurites on DCX cells, a key process for synaptic integration, to a greater degree than adult-initiated exercise. Together the data here show that exercise during the adolescent period compared to adulthood differentially affects cognitive processes and the development of new hippocampal neurons in later life.

Interindividual differences in neonatal sociality and emotionality predict juvenile social status in rhesus monkeys.

In humans, socioeconomic status (SES) has profound outcomes on socio-emotional development and health. However, while much is known about the consequences of SES, little research has examined the predictors of SES due to the longitudinal nature of such studies. We sought to explore whether interindividual differences in neonatal sociality, temperament, and early social experiences predicted juvenile social status in rhesus monkeys (Macaca mulatta), as a proxy for SES in humans. We performed neonatal imitation tests in infants' first week of life and emotional reactivity assessments at 2 and 4 weeks of age. We examined whether these traits, as well as the rearing environment in the first 8 months of life (with the mother or with same-aged peers only) and maternal social status predicted juvenile (2-3 years old) social status following the formation of peer social groups at 8 months. We found that infants who exhibited higher rates of neonatal imitation and newborn emotional reactivity achieved higher social status as juveniles, as did infants who were reared with their mothers, compared to infants reared with peers. Maternal social status was only associated with juvenile status for infant dyads reared in the same maternal group, indicating that relative social relationships were transferred through social experience. These results suggest that neonatal imitation and emotional reactivity may reflect ingrained predispositions toward sociality that predict later outcomes, and that nonnormative social experiences can alter socio-developmental trajectories. Our results indicate that neonatal characteristics and early social experiences predict later social outcomes in adolescence, including gradients of social stratification.

Noninvasive cardiac psychophysiology as a tool for translational science with marmosets.

The importance of marmosets for comparative and translational science has grown in recent years because of their relatively rapid development, birth cohorts of twins, family social structure, and genetic tractability. Despite this, they remain understudied in investigations of affective processes. In this methodological note, we establish the validity of using noninvasive commercially available equipment to record cardiac physiology and compute indices of autonomic nervous system activity-a major component of affective processes. Specifically, we recorded electrocardiogram and impedance cardiogram, from which we derived heart rate, respiration rate, measures of high-frequency heart rate variability (indices of parasympathetic autonomic nervous system activity), and ventricular contractility (an index of sympathetic autonomic nervous system activity). Our methods produced physiologically plausible data, and further, animals with increased heart rates during testing were also more reactive to isolation from their social partner and presentation of novel objects, though no relationship was observed between reactivity and specific indices of parasympathetic or sympathetic nervous system activity.

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys.

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother-infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex-differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the "lactational programming" hypothesis on the impact of maternal-origin hormones ingested via milk.

Sex and rank affect how infant rhesus macaques look at faces.

We investigated how differences in infant sex and mothers' dominance status affect infant rhesus macaques' (Macaca mulatta) interest in visually exploring emotional facial expressions. Thirty-eight infants were presented with animated avatars of macaque facial expressions during the first month of life. Sons of high-ranking mothers looked more at faces, especially the eye region, than sons of low-ranking mothers, but no difference in looking duration was found for daughters. Males looked significantly more at eyes than females, but this effect was reversed in infants who were reared without mothers in a primate nursery facility. In addition, in mother-infant interactions, mothers of sons were more likely to gaze at their infant's face compared to mothers of daughters. Combined with previous research indicating that rhesus macaque mothers interact differently with infants based on their own rank and infant's sex, these results support the view that social experiences shape early face preferences in rhesus macaques.

Rank acquisition in rhesus macaque yearlings following permanent maternal separation: The importance of the social and physical environment.

Rank acquisition is a developmental milestone for young primates, but the processes by which primate yearlings attain social rank in the absence of the mother remain unclear. We studied 18 maternally reared yearling rhesus macaques (Macaca mulatta) that differed in their social and physical rearing environments. We found that early social experience and maternal rank, but not individual traits (weight, sex, age), predicted dominance acquisition in the new peer-only social group. Yearlings also used coalitions to reinforce the hierarchy, and social affiliation (play and grooming) was likely a product, rather than a determinant, of rank acquisition. Following relocation to a familiar environment, significant rank changes occurred indicating that familiarity with a physical environment was salient in rank acquisition. Our results add to the growing body of literature emphasizing the role of the social and physical environment on behavioral development, namely social asymmetries among peers.

First-time rhesus monkey mothers, and mothers of sons, preferentially engage in face-to-face interactions with their infants.

Face-to-face interactions between mothers and infants occur in both human and non-human primates, but there is large variability in the occurrence of these behaviors and the reason for this variability remains largely unexplored. Other types of maternal investment have been shown to be dependent on infant sex (e.g. milk production and maternal responsiveness) and maternal experience (e.g. symmetrical communication). Thus, we sought to determine whether variability in face-to-face interactions, that is, mutual gazing (MG), which are hypothesized to be important for later socio-cognitive development, could be explained by these variables. We studied 28 semi-free ranging rhesus monkey (Macaca mulatta) mother-infant dyads (6 primiparous; 12 male infants) born and reared at the Laboratory of Comparative Ethology field station at the NIH Animal Center in Poolesville, MD, across the first 90 postnatal days. Infant sex (i.e. male) was a significant predictor of maternal grooming (ß ± SE = 0.359 ± 0.164, Z = 2.19, P = 0.029) whereas both parity (i.e. first time mothers) and infant sex (i.e. male) significantly predicted MG (parity: ß ± SE = -0.735 ± 0.223, Z = -3.30, P < 0.001; infant sex: ß ± SE = 0.436 ± 0.201, Z = 2.17, P = 0.029). Separation from the mother (outside of arm's reach) was not influenced by parity or infant sex. Together with existing literature, these findings point toward differential maternal investment for sons versus daughters. Mothers may be investing differentially in sons, behaviorally, to ensure their future social competence and thus later reproductive success. Collectively, our findings add to the literature that is beginning to identify early life experiences that may lead to sex differences in neurological and behavioral development.

Development of a cognitive testing apparatus for socially housed mother-peer-reared infant rhesus monkeys.

Though cognitive testing of infant monkeys has been practiced for the past 40 years, these assessments have been limited primarily to nursery-reared infants due to the confounds of separating mother-reared infants for assessments. Here, we describe a pilot study in which we developed a cognitive testing apparatus for socially housed, mother-peer-reared rhesus macaques under 1 year of age (Macaca mulatta) that allowed the infants to freely return to their mothers for contact comfort. Infants aged 151.2 ± 18.3 days (mean ± SEM; n = 5) were trained and tested on an object detour reach task. Infants completed training in 5.0 ± 0.2 days, and completed testing in 6.2 ± 0.9 days. Across 4 days of testing, infants improved to nearly errorless performance (Friedman test: χ(2) = 13.27, df = 3, p = 0.004) and learned to do the task more quickly (Friedman test: χ(2) = 11.69, df = 3, p = 0.009). These are the first cognitive data in group-housed, mother-peer-reared rhesus monkeys under 1 year of age, and they underscore the utility of this apparatus for studying cognitive development in a normative population of infant monkeys.

A critical examination of Illinois' child welfare information systems and its utility for identifying and monitoring children and youth with special health care needs for front- and back-end users.

BACKGROUND: Children and youth with special health care needs (CYSHCN) are at an increased risk for abuse and neglect, and they experience worse outcomes during and after child protective services involvement, as compared to typically developing peers. Identifying and monitoring these vulnerable youth is essential for reducing disparities and optimizing service delivery. However, many states, including Illinois, lack systems for efficient identification and monitoring. OBJECTIVE: (1) To examine existing Illinois Department of Children and Family Services (ILDCFS) data systems to determine if a source exists that would allow for identification and monitoring of CYSHCN; and (2) To understand ILDCFS personnel's experience with identifying and monitoring CYSHCN. METHODS: First, relevant ILDCFS data sources were identified, pulled, and examined for completeness. Second, ILDCFS personnel completed a mixed-methods survey assessing how they identified and monitored CYSHCN as well as what barriers they experienced in conducting these activities. Conceptual content analysis was utilized to obtain counts of different methods used to track and monitor youth as well as to identify barriers to these processes. RESULTS: Six data sources were identified as being relevant through ILDCFS' data systems, but none were complete enough for effectively tracking and identifying CYSHCN. Survey responses indicated no standardized, systemic process for identifying and monitoring CYSHCN, with many personnel relying on reports from other involved parties. CONCLUSIONS: In order to identify CYSHCN and monitor well-being, a standardized process within ILDCFS systems is needed to provide complete, accurate, and timely data for CYSHCN, allowing for both system-wide and individual-level monitoring.

Perceived Parent Needs for Improving Parent Participation in School-Based Therapies for Children with Disabilities Using the Parent-Therapist Partnership Survey.

Rehabilitative and habilitative therapies can help children with disabilities increase independence and overall wellbeing. However, children and their caregivers face many barriers to accessing these therapies and often rely on the school for therapy access. Given the limited resources available within the special education system, increasing parent involvement in special education therapies could improve service delivery. However, providers must first understand what parents need to participate in therapies before attempting to engage families. 217 parents completed an online survey consisting of the Parent-Therapist Partnership Survey and demographic questionnaires about theirfamiliesand their child[ren] with disabilities. The percentage of needs parents endorsed as important and thepercentageofimportantneedsendorsedasunmetwere calculated. Differences across demographic variables were assessed. Overall, parents reported an average of 75% of needs as important with significantly more needs endorsed as important regarding being an informed, engaged member of the child's care team (M = 83%) than needs related to support and guidance (M = 65%, p < 0.001). Furthermore, parentsreportedan average of 58% of important needs as unmet, with no significant differences in subscale averages. Significant associations were found for race/ethnicity, education, income, partner availability, number of children with disabilities in the household, transportation access, neighborhood opportunities, parent efficacy and social, emotional, and behavioral concerns. Parents reported a high percentage of needs as important, but a large percentage of these important needs were considered unmet. Significant disparities based on racial/ethnic identities and access to resources were found. In order to successfully engage parents in special education therapy activities, providers must work to understand and address parents' engagement needs, paying special attention to each family's unique circumstances to optimize engagement.

Time-of-Flight MRA of Intracranial Aneurysms with Interval Surveillance, Clinical Segmentation and Annotations.

Intracranial aneurysms (IAs) are present in 2-6% of the global population and can be catastrophic upon rupture with a mortality rate of 30-50%. IAs are commonly detected through time-of-flight magnetic resonance angiography (TOF-MRA), however, this data is rarely available for research and training purposes. The provision of imaging resources such as TOF-MRA images is imperative to develop new strategies for IA detection, rupture prediction, and surgical training. To support efforts in addressing data availability bottlenecks, we provide an open-access TOF-MRA dataset comprising 63 patients, of which 24 underwent interval surveillance imaging by TOF-MRA. Patient scans were evaluated by a neuroradiologist, providing aneurysm and vessel segmentations, clinical annotations, 3D models, in addition to 3D Slicer software environments containing all this data for each patient. This dataset is the first to provide interval surveillance imaging for supporting the understanding of IA growth and stability. This dataset will support computational and experimental research into IA dynamics and assist surgical and radiology training in IA treatment.
