Turkish Journal of Chemistry

Studies on natural products with anticancer properties have gained more importance in recent years in order to not damage healthy tissues during cancer treatments or to perform the treatment causing the least damage. Curcumin is a common natural product with anticancer properties, but its low solubility, instability, and bioavailability have limited its use in clinical applications in cancer research. As a proposed solution to this problem, a new mesoporous organosilica nanocarrier (MON-A) functionalized with a 1,2-diphenylethane-1,2-diamine structure capable of pH-controlled release was prepared in this study. MON-A was characterized by TGA, BET, XRD, FT-IR, and SEM-EDS analyses. Dispersion of MON-A …

Shaping A Crisis, Constructing Addiction: Discursive Depoliticization Of British Columbia’S Drug Policy, Hope Robinson Dec 2023

Shaping A Crisis, Constructing Addiction: Discursive Depoliticization Of British Columbia’S Drug Policy, Hope Robinson

Emancipations: A Journal of Critical Social Analysis

This analysis sets out to inquire why the comprehensive public health response to the alarming surge in illicit opioid and stimulant-related fatalities in the Canadian province of British Columbia has not yielded the intended results, despite its forward-thinking policies grounded in a concern for health over criminalization (Govt of BC, 2016; Burton et al., 2021). I will claim that this purportedly progressive approach to public health has been ineffective because it fails to address the socio-political drivers of the overdose crisis. Relating the work of cultural anthropologist Philippe Bourgois on drug use as a coping mechanism and Carol Bacchi’s ontopolitical …

Enigmatic Cervicofacial Actinomycosis Post Radiotherapy - A Case Report, Amanda Phoon Nguyen Dec 2023

Enigmatic Cervicofacial Actinomycosis Post Radiotherapy - A Case Report, Amanda Phoon Nguyen

Journal of Dentistry Indonesia

Although thought to be uncommon, it is believed that cervicofacial actinomycosis is underreported due to frequent misdiagnosis. It has been called the “most misdiagnosed disease by experienced clinicians”. A wide range of dental procedures or trauma, including tooth eruption, may precipitate actinomycosis by enabling microorganisms to penetrate the deeper tissue layers via an entry point. This infective disease is significant due to its potentially aggressive and locally destructive nature. This case describes a patient diagnosed with cervicofacial actinomycosis. Her history prior to this was significant for proliferative verrucous leukoplakia, and T4aN0M0 (AJCC 7th Edition) squamous cell carcinoma of the right …
