Guiding molecular assembly of peptides into rationally engineered nanostructures remains a major hurdle against the development of functional peptide-based nanomaterials. Various non-covalent interactions come into play to drive the formation and stabilization of these assemblies, of which electrostatic interactions are key. Here, the atomistic mechanisms by which electrostatic interactions contribute toward controlling self-assembly and lateral association of ultrashort β-sheet forming peptides are deciphered.

Introduction: Interventions related to the perpetration of Domestic Violence and Abuse (DVA) have gained traction over the past several years, in response to dissatisfaction by victims, an inadequate response from the criminal justice system, increased demand on police time and a lack of rehabilitative responses to the perpetration of domestic abuse. The CARA model is a conditional diversionary caution, offered by police for first time offenders of 'standard' or 'medium risk' domestic abuse, that engages perpetrators in awareness raising workshops and signposts them onto further services. Although quasi-experimental studies have indicated that CARA showed promise at reducing reoffending, the CARA model has yet to be evaluated nationally and there is no qualitative evidence related to understanding or learning about the lived experience of perpetrators and victims as they engage with the intervention.

Poor-quality, substandard and falsified, medicines pose a significant public health threat, particularly in low-middle-income countries. A retrospective study was performed on Kenya's Pharmacovigilance Electronic Reporting System (2014-2021) to characterize medicine quality-related complaints and identify associations using disproportionality analysis. A total of 2767 individual case safety reports were identified, categorized into medicines with quality defects (52.

This paper serves as a Part II follow-up of our research investigations performed on the molecular structures of silver(I)-fluoride (SF) and diammine-silver(I) fluoride (SDF) complexes in solution-based commercial products for clinical application, their precise chemical compositions, and their nature in aqueous solution, the latter including rapid fluoride-exchange processes at the silver(I) ion centre monitored by F NMR analysis (Part I). Part I of this series also explores the mechanisms of action (MoA) of these complexes, and is therefore largely focused on their chemical reactions with constituents of human saliva, which has access to their sites of application. Such reactions were found to slowly promote the generation of potentially physiologically-active Ag/AgCl nanoparticles from primarily-generated discoloured silver(I) chloride (AgCl) precipitates, a process involving salivary electron-donors such as thiocyanate and L-cysteine.

Article Synopsis
  • The study investigates the molecular structure, composition, and interactions of silver(I)-diammine fluoride (SDF) and silver(I)-fluoride (SF) solutions, which are used in treating dental caries, highlighting the lack of prior research in this area.
  • Advanced techniques such as high-resolution NMR spectroscopy and SEM analyses revealed differences in the fluoride exchange dynamics of SDF and SF, along with the generation of silver chloride nanoparticles (CSNPs) when treated with human saliva.
  • Results suggest that the SDF product contains high levels of fluoride and ammonia, and that CSNPs formed from the interaction of these solutions with saliva incorporate various biomolecules, indicating a complex interplay when used in dental treatment.

A number of solvents, (Solstice PF, Opteon SF33 and Amolea AS-300), are compared to the recommended carrier solvent of HFE7100 for the ninhydrin and 1,2-indandione formulations. As the supply of HFE7100 will cease by the end of 2025, suitable alternatives are required in the short-term to ensure the detection of latent fingermarks on porous surfaces is still effective. Although these solvents, with the exception of Amolea AS-300, are classified as per- and polyfluoroalkyl substances (PFAS); they are not classed as hazardous.

It is becoming increasingly more significant to detect and separate hormones from water sources, with the development of synthetic recognition materials becoming an emerging field. The delicate nature of biological recognition materials such as the antibodies means the generation of robust viable synthetic alternatives has become a necessity. Molecularly imprinted nanoparticles (NanoMIPs) are an exciting class that has shown promise due the generation of high-affinity and specific materials.

This paper examines the mental health impacts of poor quality private-rented housing in the north of England during the UK's first COVID-19 lockdown. The paper draws on data collected from semi-structured telephone interviews with 40 renters in the private-rented sector. We use the Power Threat Meaning Framework to highlight how substandard housing was a social and material vulnerability which, underpinned by powerlessness, resulted in threats that created and exacerbated the mental-ill health of precarious private renters.

The aim of the paper is to illustrate how the housing system in the United Kingdom (UK) has contributed to creating vulnerabilities during the COVID-19 pandemic. Drawing on the concept of ontological security we look at how living with housing insecurity whilst enduring poor housing conditions has impacted the lives of those living in households. The paper draws on semi-structured interviews with 50 residents and 8 housing professionals.

Access to affordable, safe, effective, and quality-assured medicines by a patient is important for good health outcomes. Unfortunately, there is sparse literature published on the pharmaceutical enablers that may increase the sale of a substandard and falsified (SF) medicine to a patient in Kenya. The review highlights some of the factors that may facilitate the entry of SF medicines into the legitimate pharmaceutical supply chain and discusses their impact on patient access to medicines.

Bladed weapons are frequently encountered in violent crime offences including street based and armed robberies, murder, sexual assaults and terrorism. A study was conducted involving four frequently encountered clothing fabrics: t-shirt (knitted cotton), denim jeans (twill woven cotton), long sleeved top (knitted synthetic blend), and skirt (non-woven faux leather) and five knives to investigate any damage resulting from a downward stabbing motion, with 300 stabs in total. Any resultant penetrating severance damage was then photographed, measured and analysed.

Despite recent advances in DNA technology, fingermark evidence remains a fundamental method of ascertaining an individual's identity. Latent fingermarks are the commonest type of fingermark encountered at crime scenes. The Fingermark Visualisation Manual provides crime scene practitioner's with sequential information regarding which enhancement processes are best suited for a range of deposition surfaces (Bandey et al.

Article Synopsis
  • This study examined how the attraction between ibuprofen and chitosan affects the drug's crystal behavior, solubility, and dissolution efficiency, aiming to improve drug delivery methods.
  • Amorphous nanoparticles of ibuprofen were created using a controlled drug-polymer assembly, and various analytical techniques confirmed the interaction and characteristics of the nanoplex.
  • Results showed that the nanoplex had significantly improved solubility and dissolution rates compared to pure ibuprofen, indicating that the ibuprofen-chitosan combination could enhance drug delivery through diverse release profiles.

Aims: In England and Wales, doctors are charged with a responsibility either to report a death to the coroner or issue a medical certificate specifying cause of death. A lack of formal prescriptive or presumptive oversight has resulted in the promulgation by individual coroners of local reporting regimes. The study reported here identified overall and gendered variations in local reporting rates to coroners across the jurisdictions of England and Wales, consistent over time.
