Bioorganometallic Tagging Of N-Acetylhistamine With An Fe(Co)₃ Unit: Synthesis, X-Ray Structure, And Protonation Behavior, Salah Merniz, Louiza Himed, Rofia Djerri, Belkis Akachat

Turkish Journal of Chemistry

This study highlights the potential of organometallic carbonyl complexes as selective markers for biomolecules, enabling sensitive infrared (IR) detection. The regio- and stereoselective coupling of N-acetylhistamine, a histidine analogue, with the precursor complex 1 [Fe(CO)₃(1,4-η⁵-N-pyridiniocyclohexa-1,3-diene)] BF₄ affords the labeled complex 3 [Fe(CO)₃(1,4-η⁵-N-acetylhistaminocyclohexa-1,3-diene)]. X-ray diffraction (XRD) confirms the exo stereochemistry and reveals a rigid, well-defined architecture. IR and 1H nuclear magnetic resonance spectroscopic studies combined with IR-monitored acid–base titration demonstrate the complex’s stability in aqueous media between pH 5 and 8, alongside a modest increase in basicity relative to the free ligand. These findings establish the Fe(CO)₃ moiety as a robust …

Absolute Extraction: Utilizing Rural Critical Criminology To Examine Appalachia’S Toxic Dependence On Extractive Industries, Andrew Kennedy

The Mid-Southern Journal of Criminal Justice

Brought forth by common rhetoric, Appalachia is often viewed as the closest space to that of an empyrean domain. Separated from the sleepless city, its allure rests in its created identity of a quiet, green escape from the city, which offers serenity on all fronts. Although Appalachia can fulfill this profile, such an ascension ignores the burning yellow grass below. The purpose of this paper is to examine the history of the destruction of Appalachia through the lens of extractive industries and the region’s designation as a sacrifice zone. Through the application of rural critical criminology, this paper holds that …

Bridging The Gap Between Substance Use Treatment Barriers In Rural Areas, Dakota Baker

The Mid-Southern Journal of Criminal Justice

The purpose of this paper is to examine the continued concern about substance abuse/misuse and limited access to treatment in rural areas. Rural areas lack the adequate treatment needed to combat substance use disorder (SUD), mainly due to the lack of sufficient providers trained to identify, treat, and support those dealing with SUD. Additional barriers such as the high cost of treatment, stigma surrounding substance use disorders, geographical barriers, and the criminalization of substance abuse are other barriers that will be discussed in this paper (Griffin & Botvin, 2010; Hargons et al., 2023; Khazaee-Pool et al., 2024; National Center for …

Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton

Theses - ALL

Accruing evidence suggests a significant relationship between sleep disturbances and disordered eating. Early adolescence is a period of heightened vulnerability for sleep disturbances and disordered eating. However, the longitudinal relationship between sleep disturbance and disordered eating remains unclear in early adolescent samples. The current study aims to examine if sleep disturbance longitudinally predicts disordered eating in early adolescents three years later, how the odds of having clinically significant disordered eating change per each unit increase in sleep disturbance, and if emotion dysregulation mediates these relationships. It is hypothesized that baseline sleep disturbance will predict greater disordered eating at follow-up, and …
