Topological descriptors and connectivity analysis of coronene fractal structures: insights from atom-bond sum-connectivity and Sombor indices
Authors: Zhang Xiujun , Aftab Sahar , Noureen Sadia , Aslam Adnan , Ibrahim Sobhy M. 
Published: February 2025

Abstract
Coronene, a polycyclic aromatic hydrocarbon (PAH) consisting of six benzene rings fused in a hexagonal arrangement, exhibits a fractal structure that is significant in various fields such as condensed matter physics, materials science, surface science, and interdisciplinary areas like nanotechnology and astrochemistry. Topological descriptors, which characterize the geometric and connectivity properties of a structure independently of specific spatial coordinates, are crucial for understanding coronene’s complex geometry and connectivity. In this study, we compute the atom-bond sum (ABS)-connectivity index and four versions of the Sombor indices for three different configurations of the coronene fractal structure: Zig-zag Hexagonal Coronene Fractal (ZHCF), Armchair Hexagonal Coronene Fractal (AHCF), and Rectangular Coronene Fractal (RCF). To assess their chemical applicability, we develop linear regression models to estimate the physicochemical properties boiling point (BP) and molecular weight (MW) of benzene derivatives using these topological indices. The regression parameters for each case are provided, and the results show that the ABS index outperforms all other topological indices, making it the most effective predictor for these properties.
Study on the Rheological Properties and Modification Mechanism of Graphene/Rubber Composite-Modified Asphalt
Authors: Lin Mei , Lei Yu , Li Ping , Li Wang Zhao 
Published: February 2025

Abstract
To explore the rheological properties and the modification mechanism of graphene/rubber composite-modified asphalt, a dynamic shear rheometer and low-temperature bending rheometer were used to study the high and low-temperature rheological properties of graphene/rubber composite-modified asphalt. Second, the microstructure and chemical structure of the asphalt were characterized by using Fourier transform infrared spectroscopy and optical microscopy, and the component model of asphalt was constructed with molecular dynamics simulation technology to explore the modification mechanism of graphene/rubber composite-modified asphalt. The results show that compared with rubber-modified asphalt, graphene/rubber composite-modified asphalt effectively improves the high-temperature deformation resistance and low-temperature crack resistance of asphalt, but the ability of graphene to improve the low-temperature performance of asphalt is limited at −24°C or even lower temperatures. The addition of graphene promotes the swelling development of rubber, improves the bonding stability between rubber and resin, and enhances the compatibility between rubber and asphalt systems. Graphene can weaken the aggregation behavior of rubber and asphaltene, and the distribution of rubber and asphaltene in asphalt is more uniform, further improving the overall stability of the asphalt system. Graphene promotes the adsorption of lightweight components by rubber, leading to a decrease in the diffusion coefficients of saturated and aromatic components in asphalt systems. This is also an important reason for the improved high-temperature performance of graphene/rubber-modified asphalt.

Published: February 2025

Opioid use disorder constitutes a major health and economic burden, but our limited understanding of the underlying neurobiology impedes better interventions. Alteration in the activity and output of dopamine (DA) neurons in the ventral tegmental area (VTA) contributes to drug effects, but the mechanisms underlying these changes remain relatively unexplored. We used translating ribosome affinity purification and RNA sequencing to identify gene expression changes in mouse VTA DA neurons following chronic morphine exposure. We found that expression of the neuropeptide neuromedin S (Nms) is robustly increased in VTA DA neurons by morphine. Using an NMS-iCre driver line, we confirmed that a subset of VTA neurons express NMS and that chemogenetic modulation of VTA NMS neuron activity altered morphine responses in male and female mice. Specifically, VTA NMS neuronal activation promoted morphine locomotor activity while inhibition reduced morphine locomotor activity and conditioned place preference (CPP). Interestingly, these effects appear specific to morphine, as modulation of VTA NMS activity did not affect cocaine behaviors, consistent with our data that cocaine administration does not increase VTANmsexpression. Chemogenetic manipulation of VTA neurons that express glucagon-like peptide, a transcript also robustly increased in VTA DA neurons by morphine, does not alter morphine-elicited behavior, further highlighting the functional relevance of VTA NMS-expressing neurons. Together, our current data suggest that NMS-expressing neurons represent a novel subset of VTA neurons that may be functionally relevant for morphine responses and support the utility of cell type-specific analyses like TRAP to identify neuronal adaptations underlying substance use disorder.Significance StatementThe opioid epidemic remains prevalent in the U.S., with more than 70% of overdose deaths caused by opioids. The ventral tegmental area (VTA) is responsible for regulating reward behavior. Although drugs of abuse can alter VTA dopaminergic neuron function, the underlying mechanisms have yet to be fully explored. This is partially due to the cellular heterogeneity of the VTA. Here, we identify a novel subset of VTA neurons that express the neuropeptide neuromedin S (NMS).Nmsexpression is robustly increased by morphine and alteration of VTA NMS neuronal activity is sufficient to alter morphine-elicited behaviors. Our findings are the first to implicate NMS-expressing neurons in drug behavior and thereby improve our understanding of opioid-induced adaptations in the VTA.
Using MedSMA℞T Families for Opioid Safety Education: Emergency Department Staff Perspective
Authors: Nadi Sara , Hurst Irene A , Abraham Olufunmilola 
Published: February 2025

OBJECTIVES
Misuse of opioid medications was associated with 75% of drug-related deaths in 2020. Although Emergency Departments (EDs) frequently prescribe opioids, no preventative interventions have been implemented to educate adolescents and their families on safe opioid use. This study aimed to characterize ED staff’s perspectives on implementing the MedSMA℞T Families intervention in the ED to improve opioid education and safety among adolescents.

METHODS
ED staff played the MedSMA℞T game, completed a survey, and were asked open-ended questions regarding their experience interfacing with the technology. Transcripts were coded using NVivo to conduct content analysis. The analysis integrated the Systems Engineering Initiative for Patient Safety (SEIPS) 3.0 model into the interventiond.

RESULTS
A total of 23 ED staff were recruited. Staff reported that the game was more interactive and age-appropriate for adolescents compared to other educational materials in the ED. Reflecting on the care team, nurses and child life specialists were identified as appropriate roles for delivering the game to patients. Moreover, staff buy-in, training, and ED workflows were recognized as important factors within the organizational conditions allowing for game implementation. Space, loudness, and allocated resources in the ED were perceived as challenges to game implementation. Lastly, waiting room gameplay was thought to be the most efficient setting of game implementationn.

CONCLUSIONS
MedSMA℞T Families can be efficiently implemented into ED settings. It is one of the first serious games to target opioid education and to engage and better retain the attention of younger patients and was well received by ED staff.
Dot-blot assay with AlCl3 reagent for rapid screening of total flavonoid content in food and herbal medicine materials
Authors: Sutrisno Chetiza Aurelie Putri , Kartini Kartini 
Published: February 2025

AbstractThe determination of total flavonoid content (TFC) through the aluminum chloride (AlCl3) colorimetric test utilizing spectrophotometry is commonly used as a parameter for evaluating the quality of processes as well as food and herbal medicines materials. Nonetheless, it is laborious, lengthy, and necessitates substantial amounts of chemicals. This study aims to develop and validate the dot-blot assay with AlCl3 reagent for determining TFC in plant materials. In this method, the samples were not subjected to chromatography; instead, the plates were derivatized using AlCl3 in ethanol immediately after the application of samples and evaporation the solvent. The Al(III)-flavonoid complex was scanned (421 nm) using a TLC-scanner. The validation of the method was conducted on stability, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, and robustness. The TFC of samples determined by dot-blot assay and spectrophotometry was subsequently analyzed using linear regression and Pearson correlation. The dot-blot assay for determining TFC met the stability parameter (RSD = 1.31–8.25%), intraday precision (RSD = 2.20–6.11%), inter day precision (RSD = 1.56%), linearity (r2 = 0.9928), LOD (251.03 ng/spot), LOQ (760.71 ng/spot), accuracy (recovery = 70.81–75.61%), and robustness (RSD = 2.55 and 7.60%). There was a very strong positive linear relationship between the dot-blot assay method and spectrophotometry, with a linear regression coefficient of 0.9078 and a Pearson correlation coefficient of 0.911. The proposed method proved to be simpler, faster, and more economical for determining TFC. Thus, the method was beneficial in providing references for enhancing the quality control of food and herbal medicines.

Este artigo objetiva apresentar a base teórica e os procedimentos metodológicos do Córpus de Tratados de Fronteira do Brasil, firmados, inicialmente, pelos estados europeus e, depois, pelo Brasil e os países sul-americanos, entre os séculos XVI a XX. A justificativa (e, ao mesmo tempo, diferencial) deste córpus é sua proposta de documentar a comunicação humana numa simetria social entre interlocutores, situação em que apenas poucos podem participar e assumir compromissos deônticos para seus respectivos estados nacionais, afinal o estabelecimento de uma fronteira é algo extraordinário e tem o objetivo de ser perene. No plano retórico, a delimitação fronteiriça simboliza a escolha do entendimento frente ao embate bélico. Em razão disso, o tratado configura-se como uma resposta textualmente estratégica, sendo, por isso, categorizado pela Retórica da Situação como uma resposta retórica acionada pelos interlocutores sempre que possível e necessário (Procópio, 2020).
