Enhanced il-6 and il-12b gene expression after SARS-CoV-2 infection in leprosy ...

Experts have called attention to the possible negative impact of the coronavirus disease 2019 (COVID19)–related cytokine storm syndrome on the progression of leprosy-related disabilities. We assessed the frequency of reactional states in patients co-infected with Mycobacterium leprae and severe acute respiratory syndrome (SARS) coronavirus (CoV) 2 (SARS-CoV-2). We consecutively included patients during the firs...

Molecular and cellular biomarkers of COVID-19 prognosis : protocol for the pros...

Background: Since the beginning of the COVID-19 pandemic, the world’s attention has been focused on better understanding the relation between the human host and the SARS-CoV-2 virus, as its action has led to hundreds of thousands of deaths. Objective: In this context, we decided to study certain consequences of the abundant cytokine release over the innate and adaptive immune systems, inflammation, and hemostas...

SARS-CoV-2/DENV co-infection : a series of cases from the Federal District, Mid...

Background: Since the novel coronavirus disease outbreak, over 179.7 million people have been infected by SARS-CoV-2 worldwide, including the population living in dengue-endemic regions, particularly Latin America and Southeast Asia, raising concern about the impact of possible co-infections. Methods: Thirteen SARS-CoV-2/DENV co-infection cases reported in Midwestern Brazil between April and September of 2020 a...

Activity of Fabaceae species extracts against fungi and Leishmania : vatacarpan...

Leishmaniasis and fungal infection treatment efficacy is limited by toxicity and ever increasing resistance to available drugs, requiring development of alternative compounds. The richness of Cerrado plant antimicrobial secondary metabolites justifies screening of Fabaceae species extracts: Enterolobium ellipticum Benth., Sclerolobium aureum (Tul.) Baill. and Vatairea macrocarpa(Benth.) Ducke, against Leishmani...

Clusiaxanthone and tocotrienol Series from Clusia pernambucensis and their anti...

A análise fitoquímica do extrato acetato de etila da casca do caule de Clusia pernambucensis G. Mariz, Clusiaceae, uma espécie do Cerrado brasileiro, conduziu ao isolamento e caracterização completa de uma nova xantona, 1,7-dihidróxi-2-(3-metil-2-butenil)-6',6'-dimetilpirano(2',3':3,4) xantona, denominada clusiaxantona. Quatro tocotrienóis ainda não relatados nesta espécie também foram isolados. Um derivado foi...

Glicoalcaloides antifúngicos, flavonoides e outros constituintes químicos de So...

Two glycoalkaloids: solamargine and solasonine; three flavonoids: tiliroside, 7-O-α-L-ramnopyranosyl-kaempferol and 3-O-[ß-D-glucopyranosyl-(1→6)-α-L-ramnopyranosyl]-7- O-α-L-ramnopyranosyl-kaempferol, in addition to the tripeptide Leu-Ile-Val, the aminoacid proline and the eicosanoic acid were isolated from Solanum asperum (Solanaceae). The structures of all compounds were determined by interpretation of their...
