The Anonnaceae family has 2,500 species and 135 genera, which has about 14 representatives of species in Brazil,including Pseudoxandra cuspidata. The objective of this research was to study the aqueous-acid extract of P. cuspidata, evaluatingits antioxidant, larvicidal, antimicrobial and cytotoxic potential. In the preliminary phytochemical analysis, there were positivity toorganicacids and alkaloids. Inhibitory Activity of EAA was 65% against DPPH. The AAE presented to A. Salina nauplii at LC50%of 600.79 μg/mL for a periodof 24 hours. In relation to larvicidal activity to Aedes aegypti intermediates, AAE presented the LC50%in 24 Hours of 475.91 ppm and 290.73 ppm in 48 Hours. Regarding the antimicrobial action, the EAA presented 50 mg/mL MIC forP. Aeruginosa and MBC at 100 mg/mL, and for S. aureus it presented MIC of 50 mg/mL and did not present MBC. This researchcharacterized the presence of alkaloids and organicacids present in the aqueousacid extract of P. cuspidata. The extract presentedlowtoxicity in relation to the microcrustacean A. salina. It also had a relevant antioxidant potential (65% of Inhibition),larvicidalaction considered effective, antimicrobialaction for both P. Aeruginosa and S. Aureus even did not present bactericidalaction.

Objective: To evaluate gene polymorphisms and their association with susceptibility to ***: A retrospective case-control study was performed with 262 subjects,comprising 78 dengue fever(DF) patients, 49 dengue hemorrhagic fever(DHF) patients and 135 healthy controls. Genotypic and allelic profiles were identified using polymerase chain reaction based in real time and amplification-refractory mutation ***: We observed a protective association of IL-10(-819 C/T) C allele(P = 0.028,OR = 0.56, CI = 0.34–0.91) against DHF, while the C/T(P = 0.047, OR = 2.10,CI = 1.01–4.38) and T/T(P = 0.008, OR = 3.82, CI = 1.38–10.59) genotypes were associated with DHF and DF, respectively. The dominant model TNFA-308 GA + AA(P = 0.043, OR = 0.45, CI = 0.20–1.00) genotypes were found to have protective effect against dengue infection. A protective association among the IFNG(+874 A/T) A/T genotype against DF(P = 0.02, OR = 0.46, CI = 0.24–0.89) and DHF(P = 0.034,OR = 0.43, CI = 0.19–0.95) was observed. When the studied single-nucleotide polymorphism was analyzed in combination, the combination GTA(P = 0.022, OR = 2.95,CI = 1.18–7.41) was statistically significantly associated with susceptibility to DF and the combination GCT(P = 0.035, OR = 0.28, CI = 0.08–0.90) with protection against the development of ***: This research identifies the association of the IFNG(+874 A/T), TNFA(-308 G/A), IL-10(-819 C/T) genotypes as a factor for protection, susceptibility and severity to dengue.
