1. Com quanto tempo de evolução da doença, em caso de suspeita de dengue, está indicada a solicitação de sorologia?
A partir do sexto dia do início dos sintomas, faz-se a sorologia pelo Método Enzyme-linked Immunosorbent Assay ( Elisa); detecção de antígenos virais: NS1, isolamento viral, RT-PCR e imunohistoquímica. Devem ser solicitados até o quinto dia do início dos sintomas.
Se positivos confirmam o caso; se negativos, uma nova amostra para sorologia I

2. Pode-se utilizar inibidores da enzima conversora de angiotensina (inibidores da ECA) como captopril ou enalapril ou bloqueadores do receptor de angiotensina (BRA) como losartana em pacientes que apresentam insuficiência renal crônica com albuminúria ou associada a diabetes tipo 2?
O uso de inibidores da ECA e BRA não é contraindicado em pacientes que apresentam insuficiência renal crônica com albuminúria ou associada a diabetes. Pelo contrário, nesses pacientes, essas medicações podem e devem ser utilizadas, pois diminuem a excreção urinária de proteínas e retardam a progressão da doença renal.
Para a maioria do

3. A suplementação de vitamina K nas gestantes em tratamento para epilepsia deve ser universal?
Não há evidências suficientes para a prescrição de vitamina K durante a gestação em todas as mulheres em tratamento medicamentoso para epilepsia, pois a suplementação de vitamina K na gestante não altera o risco de sangramento no feto.
Recomenda-se o uso da vitamina K suplementar, na dose de 10 mg, via oral, uma vez ao dia, durante o últi

4. Endothelial Progenitor Cells and NADPH Oxidase Enzyme Activity in the Development of an Aortic Aneurysm
Abstract Introduction: Endothelial progenitor cells (EPCs) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase enzyme activity may affect the vessel wall and have a role in development of aortic aneurysms. EPCs originate from hematopoietic stem cells and can be enumerated from peripheral blood samples by flow cytometry. In this study, we aimed t

5. Custodiol versus Blood Cardioplegia: Comparison of Myocardial Immunohistochemical Analysis and Clinical Outcomes
ABSTRACT Introduction: Custodiol (histidine-tryptophan-ketoglutarate) and repetitive blood cardioplegia are the solutions for myocardial protection and cardiac arrest. In this study, we aimed to compare immunohistochemical analysis, clinical outcomes, and cardiac enzyme values of Custodiol and blood cardioplegia groups. Methods: This was a randomized prosp

6. ASSESSMENT OF α-AMYLASE INHIBITION ACTIVITY BY AN OPTIMIZED AND VALIDATED IN VITRO MICROSCALE METHOD
Metabolic disorders, including hyperglycemia, characterize type-2 diabetes. One of the treatment methods used for postprandial hyperglycemia includes using potential therapeutic agents to inhibit α-amylase activity. This study utilized fractional design and the simplex method to optimize in vitro microscale assay inhibition conditions using Miller’s react

7. In vitro Antioxidant and Anticholinesterase Activities of Ouratea fieldingiana (Gardner) Eng. Leaf Extract and Correlation with Its Phenolics Profile with an in silico Study in Relation to Alzheimer’s Disease
Ouratea fieldingiana is a native medicinal plant from Northeastern Brazil and many biological properties are due to the phenolic constituents. The objective of this work was performing the characterization of O. fieldingiana leaf constituents to correlate with antioxidant and anticholinesterase activities by in vitro and in silico studies and thus contribute

8. Artichoke for biochemistry, histology, and gene expression in obstructive jaundice
SUMMARY OBJECTIVE: This study aimed to evaluate the hepatoprotective effect of artichoke leaf extract (Cynara scolymus) in experimental obstructive jaundice. METHODS: Rats were separated into three groups, namely, sham, control, and artichoke leaf extract. Ischemia was created for 60 min, and then liver tissue and blood samples were taken at the 90th minut

9. Molecular Docking in silico Analysis of Brazilian Essential Oils Against Host Targets and SARS-CoV-2 Proteins
The inhibitory activity of thirty-one sesquiterpenes identified from Brazilian essential oils (Copaifera langsdorffii Desf., Croton cajucara Benth. and Siparuna guianensis Aublet.) were analyzed by in silico molecular docking. The compounds were characterized by gas chromatography-mass spectrometry (GC-MS) and gas chromatography with flame-ionization detecti

10. Classic and current concepts in adrenal steroidogenesis: a reappraisal
ABSTRACT Adrenal steroid biosynthesis and its related pathology are constant evolving disciplines. In this paper, we review classic and current concepts of adrenal steroidogenesis, plus control mechanisms of steroid pathways, distribution of unique enzymes and cofactors, and major steroid families. We highlight the presence of a “mineralocorticoid (MC) pat

11. Effects of artichoke leaf extract on hepatic ischemia-reperfusion injury
SUMMARY OBJECTIVE: The aim of this study was to evaluate the hepatoprotective effect and mechanism of action of artichoke leaf extract in hepatic ischemia/reperfusion injury. METHODS: Rats were divided into three groups such as sham, control, and artichoke leaf extract groups. Antioxidant enzyme activities and biochemical parameters were examined from th

12. Supercritical Carbon Dioxide Effect on Lipase-Catalyzed Geranyl Acetate Synthesis
This work provides a general insight on lipase-catalyzed synthesis of geranyl acetate through esterification of geraniol with acetic acid. Although this reaction is relatively well known, the replacement of organic solvents by supercritical fluids is fairly recent and the role of CO2 is still not completely understood. Therefore, reactions were performed wit
