Considerations for Opioid Use Disorder Treatment From Policy Makers' Experiences With COVID-19 Policy Flexibilities.

Objective: This qualitative study aimed to examine how states implemented COVID-19 public health emergency-related federal policy flexibilities for opioid use disorder treatment from the perspective of state-level behavioral health policy makers. Recommendations are given for applying lessons learned to improve the long-term impact of these flexibilities on opioid use disorder treatment.

Methods: Eleven semistructured interviews were conducted with 13 stakeholders from six state governments, and transcripts were qualitatively coded.

Reduction of Pro-Inflammatory Markers in RAW264.7 Macrophages by Polyethylenimines.

The physiological problem of chronic inflammation and its associated pathologies attract ongoing attention with regard to methods for their control. Current systemic pharmacological treatments present problematic side effects. Thus, the possibility of new anti-inflammatory compounds with differing mechanisms of action or biophysical properties is enticing.

Skin tropism during Usutu virus and West Nile virus infection: an amplifying and immunological role.

Usutu virus (USUV) and West Nile virus (WNV) are closely related emerging arboviruses belonging to the genus and posing global public health concerns. Although human infection by these viruses is mainly asymptomatic, both have been associated with neurological disorders such as encephalitis and meningoencephalitis. Since USUV and WNV are transmitted through the bite of an infected mosquito, the skin represents the initial site of virus inoculation and provides the first line of host defense.

Kynurenic Acid: A Novel Player in Cardioprotection against Myocardial Ischemia/Reperfusion Injuries.

Background: Myocardial infarction is one of the leading causes of mortality worldwide; hence, there is an urgent need to discover novel cardioprotective strategies. Kynurenic acid (KYNA), a metabolite of the kynurenine pathway, has been previously reported to have cardioprotective effects. However, the mechanisms by which KYNA may be protective are still unclear.

The interplay between lysosome, protein corona and biological effects of cationic carbon dots: Role of surface charge titratability.

Carbon dots (CDs) are nanoparticles (NPs) with potential applications in the biomedical field. When in contact with biological fluids, most NPs are covered by a protein corona. As well, upon cell entry, most NP are sequestered in the lysosome.
