Mechanochemical Functionalization of Oxidized Carbon Black with PLA.

The functionalization of carbon black (CB) represents a promising strategy to enhance its compatibility with polymers while addressing sustainability concerns. In this study, a solvent-free mechanochemical approach (ball milling) is proposed for the functionalization of oxidized carbon black (oCB) with post-consumed polylactic acid (PLA), overcoming the environmental drawbacks of conventional methods that mostly rely on toxic solvents and catalysts. The functionalized carbon black (f-CB) was characterized by Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), and thermogravimetric analysis (TGA) to confirm the successful modification.

Intersections of Structural State-Level Racism and Neighborhood Deprivation on Nutrition and Obesity for Black Adolescents.

Purpose: Black adolescents in the United States face disproportionate poor nutrition and obesity risk due to racism. Intersections of larger structural contexts that pose differential access to Black adolescents' health resources, such as state-level racism and neighborhood-level disadvantage, may govern these risks. The purpose of this correlational study was to examine the associations between state-level racism, neighborhood disadvantage, and their intersection with nutrition and obesity for Black adolescents in a longitudinal study.

Prior exposure to racial discrimination and patterns of acute parasympathetic nervous system responses to a race-related stress task among Black adults.

Black adults' prior exposure to racial discrimination may be associated with their acute parasympathetic reactivity to and recovery from a new race-related stressor. Existing analytical approaches to investigating this link obscure nuances in the timing, magnitude, and patterns of these acute parasympathetic nervous system (PNS) responses. In a re-analysis of a prior study, we utilize an hidden Markov model (HMM) approach to examine how prior experiences of racial discrimination are associated with intraindividual patterns of (1) physiological states of PNS activity and (2) patterns of and variability in transitions between these physiological states.

Myeloid clonal hematopoiesis of indeterminate potential in patients with chronic lymphocytic leukemia.

Clonal hematopoiesis of indeterminate potential (CHIP) in patients with chronic lymphocytic leukemia (CLL) has not been extensively characterized. The objective of this study was to describe the prevalence of myeloid CHIP (M-CHIP) in patients with CLL, and to determine its association with time to first treatment (TTFT) and overall survival (OS). We retrospectively analyzed data from patients participating in a prospective CLL database at the Dana-Farber Cancer Institute who had standard-of-care targeted 95-gene next-generation sequencing (NGS) performed.

Online and offline gendered racial microaggressions and sleep quality for Black women.

Objective: Poor sleep quality affects Black women in the United States. Black young adult women experience stress from gendered racial microaggressions (i.e.

"Actually, I don't do different": Black parents' perceptions of gender socialization of sons versus daughters.

This study expanded on research examining families' roles in youth gender development that has investigated boys' versus girls' family experiences by using a within-family design to study the gender socialization of brothers versus sisters from the same families. We drew from archival data collected in 2001-2002 from an ethnic homogeneous sample of Black American mother-father families ( = 128) who were raising at least one son and one daughter; the majority of youth were adolescents (range 2-31 years). In separate home interviews, mothers and fathers described whether and how they socialized their sons versus daughters about education, their futures, and racism and discrimination.

Allostatic Load in Childhood, Adolescence, and Young Adulthood: Are Assumptions of Measurement Invariance Warranted?

Overview: Allostatic load represents the cumulative toll of chronic mobilization of the body's stress response systems, as indexed by biomarkers. Higher levels of stress and disadvantage predict higher levels of allostatic load, which, in turn, predict poorer physical and mental health outcomes. To maximize the efficacy of prevention efforts, screening for stress- and disadvantage-associated health conditions must occur before middle age-that is, during childhood, adolescence, and young adulthood.

Black Young Adult Superwomen in the Face of Gendered Racial Microaggressions: Contextualizing Challenges With Acceptance and Avoidance and Emotional Eating.

Background: Black young adult women (ages 18-35) are at disproportionate risk for obesity and emotional eating. Emotional eating interventions target psychological flexibility, such as reducing experiential avoidance and increasing acceptance of food-related thoughts. Yet Black women face gendered racism, and some endorse roles that reduce psychological flexibility, such as the superwoman schema role.

Necessary, burdensome, or threatening? Awareness of Black-White disparities in health care access and self-rated health for Black and White Americans.

Awareness of racial health care inequities is one prerequisite to eliminating them. Although extant research has described awareness of racial health care inequities in the United States, the health impacts of such awareness on communities that are most impacted by these inequities remains unknown. Therefore, we examined associations between awareness of Black-White racial health care inequities and self-rated health for Black and White adults in the United States.

Boosting species evenness, productivity and weed control in a mixed meadow by promoting arbuscular mycorrhizas.

Lowland meadows represent aboveground and belowground biodiversity reservoirs in intensive agricultural areas, improving water retention and filtration, ensuring forage production, contrasting erosion and contributing to soil fertility and carbon sequestration. Besides such major ecosystem services, the presence of functionally different plant species improves forage quality, nutritional value and productivity, also limiting the establishment of weeds and alien species. Here, we tested the effectiveness of a commercial seed mixture in restoring a lowland mixed meadow in the presence or absence of inoculation with arbuscular mycorrhizal (AM) fungi and biostimulation of symbiosis development with the addition of short chain chito-oligosaccharides (CO).

Race Correction and Algorithmic Bias in Atrial Fibrillation Wearable Technologies.

Stakeholders in biomedicine are evaluating how race corrections in clinical algorithms inequitably allocate health care resources on the basis of a misunderstanding of race-as-genetic difference. Ostensibly used to intervene on persistent disparities in health outcomes across different racial groups, these troubling corrections in risk assessments embed essentialist ideas of race as a biological reality, rather than a social and political construct that reproduces a racial hierarchy, into practice guidelines. This article explores the harms of such race corrections by considering how the technologies we use to account for disparities in health outcomes can actually innovate and amplify these harms.

To social distance or to not social distance? COVID-19 social impact and safety profiles, social determinants, and mental health of Black adults.

The impact of COVID-19 on Black adults' social networks and their perceptions of the safety of social gatherings are intertwined. Yet, we know little about the role of this intersection and social determinants on Black adults' mental health. The goal of this study was to examine profiles of COVID-19 impact and safety for Black adults in the United States, their association with mental health, and the role of sociodemographic, health, and employment social determinants.

Postprandial hypotension as a predictor of respiratory failure in patients with foodborne botulinum intoxication - a case-control study in outbreak investigation.

Objectives: Botulism is a rare syndrome characterized by acute, flaccid paralysis with possible involvement of respiratory muscle-producing pump failure requiring mechanical ventilation. A predominance of autonomic involvement can occur.

Methods: We enrolled patients affected by foodborne botulism during an outbreak.

Mechano Chemical Compatibilization of Polyethylene with Graphite by Means of a Suitable Ester.

An effective non-covalent compatibilization method for graphite and low-density polyethylene is reported. To obtain this result, pyren-1-yl-stearate (P1S) was synthesized, characterized and mixed with graphite to provide a better dispersion in polyethylene matrix. The P1S improves the dispersion of carbon filler in polyethylene through non-covalent compatibilization: the pyrenyl group gives π-π stacking interactions with graphite and the stearyl chain provides van der Waals interaction with the polymer chain (specifically London dispersion forces).

Intersections of Racial/Ethnic and Religious Identities on Bodily Well-Being for Black College-Attending Emerging Adults.

Black undergraduates face threats to healthy weight and body image (i.e., bodily well-being).

Forecasting and what-if analysis of new positive COVID-19 cases during the first three waves in Italy.

The joint exploitation of data related to epidemiological, mobility, and restriction aspects of COVID-19 with machine learning algorithms can support the development of predictive models that can be used to forecast new positive cases and study the impact of more or less severe restrictions. In this work, we integrate heterogeneous data from several sources and solve a multivariate time series forecasting task, specifically targeting the Italian case at both national and regional levels, during the first three waves of the pandemic. The goal is to build a robust predictive model to predict the number of new cases over a given time horizon so that any restrictive actions can be better planned.

Resisting and countering online racial hate: Antiracism advocacy and coping online with racism as moderators of distress associated with online racism.

The emerging literature highlights online racism (e.g., racist online interactions, exposure to racially traumatizing content) as a contemporary stressor among racially/ethnically minoritized adults.

Examining Exposure to Messaging, Content, and Hate Speech from Partisan News Social Media Posts on Racial and Ethnic Health Disparities.

We investigated the content of liberal and conservative news media Facebook posts on race and ethnic health disparities. A total of 3,327,360 liberal and conservative news Facebook posts from the United States (US) from January 2015 to May 2022 were collected from the Crowd Tangle platform and filtered for race and health-related keywords. Qualitative content analysis was conducted on a random sample of 1750 liberal and 1750 conservative posts.

SOHO State of the Art Updates and Next Questions: Treatment of Lower Risk Myelodysplastic Syndromes.

MDS is a clonal stem cell neoplasm with a spectrum from lower risk disease to short term life threatening higher risk disease. The disease risk is dictated by clinical and molecular features. Majority of MDS patients including lower risk disease unfortunately succumb from disease related complications namely cytopenia.

Long-lasting impact of chitooligosaccharide application on strigolactone biosynthesis and fungal accommodation promotes arbuscular mycorrhiza in Medicago truncatula.

The establishment of arbuscular mycorrhiza (AM) between plants and Glomeromycotina fungi is preceded by the exchange of chemical signals: fungal released Myc-factors, including chitooligosaccharides (CO) and lipo-chitooligosaccharides (LCO), activate plant symbiotic responses, while root-exuded strigolactones stimulate hyphal branching and boost CO release. Furthermore, fungal signaling reinforcement through CO application was shown to promote AM development in Medicago truncatula, but the cellular and molecular bases of this effect remained unclear. Here, we focused on long-term M.
