Research ArticleOpen accessIn the abstractThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,827 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Path Analysis to Understanding the Epidemiology of Murine Typhus in South TexasHongwei Wang, Orlando M. Patricio, Fernando G. Quintana et al.This study aims to investigate statistically if there is a causality for the murine typhus endemic disease related to precipitation, temperature and the natural cycle of flea development in South Texas. Path analysis was used to determine the mediating and moderating variables that cause murine typhus disease. Three path diagram models were tested. Model 3 shows a clearer path on … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 4 Mar 2024 · 5,589 accessesView PDF Cite

Letters to the EditorOpen accessIn the abstractIs Hydroxychloroquine a Safe and Effective Choice for Covid-19 ProphylaxisRodrigo Moisés de Almeida-Leite, Tais Rondello Bonatti, Carolina Rodrigues Ponzoni et al.The authors speculate about the possibility of Hydroxychloroquine as Covid-19 Phrophylaxis in the dose of 400 mg per week. The authors compared the experience of Malaria phrophylaxis in this dose, with acceptable safety profile. Also, we compared in vitro susceptibility of SARS-Cov-2 with that of Plasmodium falciparum.
