January 2024
Article Synopsis
- Guabijú (Myrcianthes pungens) is a Brazilian fruit from the Myrtaceae family, and this study is the first to analyze its phenolic compounds using advanced techniques.
- Eighty-one phenolic compounds were tentatively identified across the fruit's peel, pulp, and seed, with eighteen specifically quantified, highlighting high levels of ellagic and gallic acids.
- The peel contained the highest concentration of these compounds, suggesting that this research could enhance product development and encourage greater consumption of guabijú.
Araçá is a Brazilian native fruit belonging to the Myrtaceae family. Although some studies already prove its health benefits, it is still necessary to explore the phenolic compounds in all its parts separately. This study aimed to investigate the free, esterified, glycosylated, and insoluble phenolics in two morphotypes of araçá, red and yellow, evaluating peel, pulp, and seed separately, using liquid chromatography coupled to mass spectrometry (LC-ESI-QqQ-MS/MS).

View Article and Find Full Text PDFBackground: Fetal RHD genotyping of cell-free fetal DNA (cff-DNA) from RhD-negative pregnant women can be used to guide anti-D prophylaxis: the knowledge of fetal RhD type can direct and restrict the use of prenatal anti-D immunoglobulin exclusively to RhD-negative women carrying a RhD-positive fetus. Since November 2019 in the region of Friuli Venezia Giulia (Italy) a prenatal screening service has been offered to RhD-negative women at 22-24 weeks of gestation.
Materials And Methods: The cff-DNA is extracted from a simple peripheral maternal blood sample to analyze the fetal RHD gene: the results are interpreted as RHD-positive fetus, RHD-negative fetus, or Inconclusive.
In this case report the hospital management of an acute, severe thrombocytopenia in a 57-year-old man in the north-east of Italy is reported. Thrombocytopenia developed immediately after the viper bite, despite the absence of clinical signs of envenomation. No hemorrhage, ecchymoses or other signs of coagulopathy developed during the hospitalization; two doses of antivenin FAB-Fragments had no effect on thrombocytopenia, which instead responded promptly to intravenous immunoglobulins (IVIg) and glucocorticoids.
