The Presence of Flavonoids in Some Products and Fruits of the Genus Eugenia: An Integrative Review
ReviewThe Myrtaceae family, one of the most prominent botanical families, is represented in Brazil
with different fruit species, rich in bioactive compounds and gastronomically appreciated.
This study aimed to carry out an integrative review on the genus Eugenia, highlighting the
pitangueira (E. uniflora L.), cagaiteira (E. dysenterica), grumixameira (E. brasiliensis), pereira
(E. klotzschiana O. Berg), and uvaieira (E. pyriformis Cambess) and which flavonoids are
present in these fruits. Articles published between 2016 and 2021 were selected from the
following databases: Google Scholar, Periódicos CAPES, Scielo, and Science Direct.
According to each database, the descriptors used as a search strategy addressed the
popular and scientific names of the five selected species, associated or not with the term
“flavonoid,” according to each database. The results showed that quercetin was the main
flavonoid identified in the fruits, and the principal extraction method used was HPLC. Other
interesting compounds, such as catechin, epicatechin, rutin, myricetin, and kaempferol,
were also found. However, the amount and type of flavonoids detected varied according to
the applied methodology. Hence, these studies highlight the importance of species of the
genus Eugenia, which promotes beneficial health effects and possible applicability to the
food and pharmaceutical industryinfo:eu-repo/semantics/publishedVersio

Neuroschistosomiasis due to Schistosoma mansoni: a review of pathogenesis, clinical syndromes and diagnostic approaches Neuroesquistossomose devido a Schistosoma mansoni: revisão da patogênese, síndromes clínicas e manejo diagnóstico
Neuroschistosomiasis (NS) is the second most common form of presentation of infection by the trematode, Schistosoma mansoni. Granulomatous inflammatory reaction occurs as a result of schistosome eggs being transmitted to spinal cord or brain via the vascular system, or by inadvertent adult worm migration to these organs. The two main clinical syndromes are spinal cord neuroschistosomiasis (acute or subacute myelopathy) and localized cerebral or cerebellar neuroschistosomiasis (focal CNS impairment, seizures, increased intracranial pressure). Presumptive diagnosis of NS requires confirming the presence of S. mansoni infection by stool microscopy or rectal biopsy for trematode eggs, and serologic testing of blood and spinal fluid. The localized lesions are identified by signs and symptoms, and confirmed by imaging techniques (contrast myelography, CT and MRI). Algorithms are presented to allow a stepwise approach to diagnosis.<br>Neuroesquistossomose (NS) é a segunda forma mais freqüente de apresentação da infecção causada pelo trematódeo Schistosoma mansoni. A inflamação do tipo granulomatosa ocorre como resultado da presença de ovos do S. mansoni que atingiram a medula espinhal ou o encéfalo via o sistema vascular ou pela migração inadvertida de vermes adultos para estes órgãos. Duas síndromes clínicas principais podem ser identificadas: a mielopatia esquistossomótica (aguda ou subaguda) e a neuroesquistossomose cerebral ou cerebelar localizada (comprometimento focal do Sistema Nervoso Central, convulsões, hipertensão intracraniana). O diagnóstico presumido da NS requer a confirmação da presença da infecção por exame microscópico de fezes ou pela biópsia retal em busca de ovos de trematódeo e testes sorológicos no sangue e no líquor. As lesões localizadas são identificadas por sinais e sintomas, e confirmadas por exames de imagem (mielografia contrastada, tomografia computadorizada e ressonância magnética). Algoritmos são apresentados para orientar uma avaliação diagnóstica seqüencial
