Disposable Lives: Covid-19, Vaccines, And The Uprising, Matiangai Sirleaf

Faculty Scholarship

Two French doctors appeared on television and publicly discussed potentially utilizing African subjects in experimental trials for a tuberculosis vaccine as an antidote to the novel coronavirus (COVID-19). Tedros Adhanom Ghebreyesus, the Director-General of the World Health Organization (WHO), denounced these kinds of racist remarks as a “hangover from ‘colonial mentality’” and maintained that “Africa can’t and won’t be a testing ground for any vaccine.” The fallout on social media was similarly swift, with Samuel Eto’o, a Cameroonian football legend, referring to the doctors as “[d]es assasins” and several others questioning the motives behind testing a vaccine on the African …

Turkish Journal of Zoology

The efficacy of both botanical pesticides and entomopathogenic nematodes (EPN) is largely dose-dependent and driven by environmental conditions. Combination of the EPNs and botanicals may enhance their efficacy; thus, we investigated the compatibility of the medicinal plants Alepidea amatymbica and Elephantorrhiza elephantina with five locally isolated EPN strains, three Steinernema (S. khoisanae, S. biddulphi and S. innovationi) and two Heterorhabditis (H. bacteriophora and Heterorhabditis sp. SGI 244). The experiments were designed to evaluate EPNs survival in plant extracts extracted using water and ethanol at 1%, 0.75%, 0.50%, 0.25% and 0.125% concentrations and nematode viability post-exposure. A concentration of 1000 IJs/mL …

The Impact Of Vertical Public Health Initiatives On Gendered Familial Care Work: Public Health And Ethical Issues, Zahra Meghani Jan 2021

The Impact Of Vertical Public Health Initiatives On Gendered Familial Care Work: Public Health And Ethical Issues, Zahra Meghani

Philosophy Faculty Publications

Rigorous evaluations of the effects of vertical public health enterprises on the health systems of low-income countries usefully identify the public health and ethical costs of those initiatives. They reveal that such narrowly focused public health ventures undermine the efforts of those countries to establish and maintain adequately resourced and well-developed national health systems, including comprehensive primary care programs. This paper argues that the scope of assessments of vertical public health ventures should be broadened to include gender as an additional axis of analysis. When members of socio-economically marginalized populations are sick with conditions that are not covered by fragmented …

Potentiation Of Recombinant Np And M1-Induced Cellular Immune Responses And Protection By Physical Radiofrequency Adjuvant, Yibo Li, Zhoufan Li, Yiwen Zhao, Xinyuan Chen

Biomedical and Pharmaceutical Sciences Faculty Publications

Nucleoprotein (NP) and matrix protein 1 (M1) are highly conserved among influenza A viruses and have been attractive targets to develop vaccines to elicit cross-reactive cytotoxic T lymphocytes (CTLs). Yet, external antigens are often presented on major histocompatibility complex class II molecules and elicit humoral immune responses. In this study, we present a physical radiofrequency adjuvant (RFA) to assist recombinant NP and M1 to elicit potent CTL responses. We found recombinant NP/M1 immunization in the presence of RFA could elicit potent anti-NP CTLs and confer significant protection against homologous viral challenges, while NP/M1 immunization alone failed to elicit significant CTL …

Enzybiotic Therapy As Treatment For Mrsa, Rachel Finkelstein Jan 2021

Enzybiotic Therapy As Treatment For Mrsa, Rachel Finkelstein

The Science Journal of the Lander College of Arts and Sciences

This paper reviews the antibacterial potential of enzybiotics against Methicillin-resistant Staphylococcus aureus (MRSA). Due to the increasing occurrence of antibiotic resistance, researchers are looking to make use of the natural antibacterial qualities of virus bacteriophages, viral derived lysins, and antimicrobial peptides to fight MRSA infections. The efficacy of bacteriophages, endolysins, and bacteriocins as potential antibacterial agents against MRSA was extensively researched through Touro’s online library database. Each of their mechanisms of action allows them to effectively lyse S. aureus cells, by essentially disrupting the peptidoglycan in the cell wall, causing it to burst. The narrow host range of these antimicrobials …

Global Stability Of A Delayed Fractional-Order Sei Epidemic Model With Logistic Growth, Saad Z. Rida, Ahmed A. Farghaly, Shaimaa A. Azoz, Fatma Hussien

Applied Mathematics & Information Sciences

In this paper, we investigate the qualitative behavior of a fractional-order susceptible-exposed-infected (SEI) model with logistic growth and time delay. In the proposed epidemic model, we assumed that the susceptible individuals grow logistically and introduced time delay in latent infected individuals equation. The basic reproduction number R0 is derived using next generation matrix to study the dynamics of the disease free and endemic equilibrium points of the system. Based on the characteristic equations and conditions of the stability of fractional-order differential systems, local stability of the two equilibrium points is discussed. Furthermore, a suitable Lyapunov function is proposed to investigate …

Lyme disease is common in the northeastern United States, but rare in the southeast, even though the tick vector is found in both regions. Infection prevalence of Lyme spirochetes in host-seeking ticks, an important component to the risk of Lyme disease, is also high in the northeast and northern midwest, but declines sharply in the south. As ticks must acquire Lyme spirochetes from infected vertebrate hosts, the role of wildlife species composition on Lyme disease risk has been a topic of lively academic discussion. We compared tick–vertebrate host interactions using standardized sampling methods among 8 sites scattered throughout the eastern …
