BackgroundResearch on traumatic brain injury (TBI) highlights the significance of counteracting its metabolic impact via exogenous fuels to support metabolism and diminish cellular damage. While ethyl pyruvate (EP) treatment shows promise in normalizing cellular metabolism and providing neuroprotection, there is a gap in understanding the precise metabolic pathways involved. Metabolomic analysis of the acute post-injury metabolic effects, with and without EP treatment, aims to deepen our knowledge by identifying and comparing the metabolite profiles, thereby illuminating the injury's effects and EP's therapeutic potential.MethodsIn the current study, an untargeted metabolomics approach was used to reveal brain metabolism changes in rats 24 h after a controlled cortical impact (CCI) injury, with or without EP treatment. Using principal component analysis (PCA), volcano plots, Random Forest and pathway analysis we differentiated the brain metabolomes of CCI and sham injured animals treated with saline (Veh) or EP, identifying key metabolites and pathways affected by injury. Additionally, the effect of EP on the non-injured brain was also explored.ResultsPCA showed a clear separation of the four study groups (sham-Veh, CCI-Veh, sham-EP, CCI-EP) based on injury. Following CCI injury (CCI-Veh), 109 metabolites belonging to the amino acid, carbohydrate, lipid, nucleotide, and xenobiotic families exhibited a twofold change at 24 h compared to the sham-Veh group, with 93 of these significantly increasing and 16 significantly decreasing (p

Moral disengagement (MD) has been consistently associated with antisocial behavior (ASB) in prior research. Limited research tested the directionality of the bivariate relationship, and most studies focused only on the direction of MD predicting ASB, even though ASB could also influence MD based on the literature on attribution and behavioral influence on attitude. Moreover, the few studies testing reciprocal associations rarely controlled for stable individual differences and did not explicitly examine the age effect to allow for a clear developmental inference. We analyzed age-based self-report antisocial behavior and moral disengagement data across ages 16–23 from 1,349 juvenile offenders (86.43% male; 20.31% White, 41.29% Black, 33.65% Hispanic) in the Pathways to Desistance Project using a random intercept cross-lagged panel model. Controlling for stable individual differences in MD and ASB and their associations along with the autoregressive effects, there was a reciprocal relationship between MD and ASB from ages 16 to 18. However, from ages 19 to 21, only ASB significantly predicted MD in the following year. There was no significant cross-lagged effect from ages 21 to 23. Our findings highlight the dynamic relationship between MD and ASB from ages 16 to 23. Youth between 16 and 18 years old may be more pliable to change with treatment/intervention due to the two-way traffic of cognition and behavior, but we also caution against treatment efforts with a heavy focus on proactive criminal thinking involving moral disengagement to reduce offending behavior beyond age 18. Public Significance Statement: The mutual influences of MD and ASB from age 16 to 18 suggest that youth at these ages are more pliable to change, and the two-way traffic in their cognition and behavior may be opportune for intervention to start a positive feedback loop. Because of the lack of effect of MD on ASB beyond age 18, we caution against treatment efforts with a heavy focus on proactive criminal thinking (e.g., moral disengagement) to reduce offending behavior.

The southern corn rootworm, Diabrotica undecimpunctata howardi Barber, is native to the US where it is a pest of peanut, Arachis hypogaea. The banded cucumber beetle, Diabrotica balteata LeConte, is native to the neotropics, but its range has expanded and currently includes most of the US peanut production area. The purpose of this study was to: (i) define seasonal variation in adult rootworm populations in peanut fields, and (ii) determine the effect(s) of proximity to a putative early season host (i.e. corn, Zea mays) and the presence of irrigation on rootworm infestation and pod injury in peanut. Seasonal abundance of adult rootworms in commercial peanut fields in Georgia was monitored in 2021 and 2022 using plant volatile lures attached to yellow sticky traps. Traps were located at 45, 90, and 180 m from the field edge in irrigated and nonirrigated peanut fields with and without a corn border. Two peaks in abundance were observed for both species in each year. Though peak abundance for the two species occurred nearly simultaneously, D. balteata was more abundant than D. u. howardi. Beetle abundance was highest in fields bordered by corn, but presence of irrigation was not as important for D. balteata as it was for D. u. howardi. Pod injury was greater in fields bordered by corn in both years, but there was no difference in pod injury between irrigated and nonirrigated fields. The number of beetles captured and incidence of pod injury within a field did not differ with distance from the field border. [ABSTRACT FROM AUTHOR]

The hydrogen storage capabilities of the metal–organic framework (MOF) CALF-20 are examined experimentally with both cryogenic and near-ambient temperatures. This framework has a pore size that is nearly ideal for cryogenic hydrogen storage. Density functional theory (DFT) studies provide insights into the hydrogen binding sites within CALF-20.

Hydrogen may play a critical role in our efforts to de‐carbonize by 2050. However, there remain technical challenges in the storage and transport of hydrogen. Metal‐organic frameworks (MOFs) have shown significant promise for hydrogen storage at cryogenic temperatures. A material that can meet the US department of energy (DOE) ultimate goal of 6.5 wt. % for gravimetric performance and 50 g/L for volumetric storage at near‐ambient temperatures would unlock hydrogen as a future fuel source for on‐board applications. Metal‐organic frameworks typically have low heat of adsorptions (i. e. 4–7 kJ/mol), whereas for storing significant quantities of hydrogen at near‐ambient temperatures, 15–25 kJ/mol is likely required. In this review we explore the current methods used (i. e., open‐metal sites, alkali dopants and hydrogen spillover) for promoting strong adsorption within MOFs. Further we discuss MOF‐based materials with respect to the technical aspects of deliverable capacity, kinetics and stability. [ABSTRACT FROM AUTHOR]

Background: Lower income is associated with high incident cardiovascular disease (CVD) and mortality. CVD is an important cause of morbidity and mortality in cancer survivors. However, there is limited research on the association between income, CVD, and mortality in this population. Methods: This study utilized nationally representative data from the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey evaluating the health and nutritional status of the US population. Our study included NHANES participants aged ≥20 years from 2003–2014, who self-reported a history of cancer. We evaluated the association between income level, prevalence of CVD, and all-cause mortality. All-cause mortality data was obtained through public use mortality files. Income level was assessed by poverty-income ratio (PIR) that was calculated by dividing family (or individual) income by poverty guideline. We used multivariable-adjusted Cox proportional hazard models through a backward elimination method to evaluate associations between PIR, CVD, and all-cause mortality in cancer survivors. Results: This cohort included 2,464 cancer survivors with a mean age of 62 (42% male) years. Compared with individuals with a higher PIR tertiles, those in the lowest PIR tertile had a higher rate of pre-existing CVD and post-acquired CVD. In participants with post-acquired CVD, the lowest PIR tertile had over two-fold increased risk mortality (Hazard Ratio (HR) = 2.17; 95% CI: 1.27–3.71) when compared to the highest PIR tertile. Additionally, we found that PIR was as strong a predictor of mortality in cancer survivors as CVD. In patients with no CVD, the lowest PIR tertile continued to have almost a two-fold increased risk of mortality (HR = 1.72; 95% CI: 1.69–4.35) when compared to a reference of the highest PIR tertile. Conclusions: In this large national study of cancer survivors, low PIR is associated with a higher prevalence of CVD. Low PIR is also associated with an increased risk of mortality in cancer survivors, showing a comparable impact to that of pre-existing and post-acquired CVD. Urgent public health resources are needed to further study and improve screening and access to care in this high-risk population. [ABSTRACT FROM AUTHOR]
