Resveratrol, a natural polyphenol, has shown promising neuroprotective effects in several in vivo and in vitro experimental models. However, the mechanisms by which resveratrol mediates these effects are not fully understood. Glutamate is the major excitatory neurotransmitter in the brain; however, excessive extracellular glutamate levels can affect neural activity in several neurological diseases.

Evidence indicates that may influence expression. This study aims to determine whether ACE1, ACE2, and TMPRSS2 mRNA expression levels, along with the ACE1 Alu 287 bp polymorphism (rs4646994), contribute to the severity and mortality of COVID-19.

All insect trypanosomatids of the subfamily Strigomonadinae harbor a proteobacterial symbiont in their cytoplasm and unique ultrastructural cell organization. Here, we report an unexpected finding within the Strigomonadinae subfamily: the identification of a new species lacking bacterial symbiont, represented by two isolates obtained from Calliphoridae flies in Brazil and Uganda. This species is hereby designated as Kentomonas inusitatus n.
View Article and Find Full Text PDFImmune thrombocytopenic purpura (ITP) is an autoimmune condition characterized by a reduced platelet count due to enhanced peripheral destruction and impaired platelet production. While thrombocytopenia is a well-documented complication of various viral infections, cytomegalovirus (CMV), a member of the Herpesviridae family, is primarily associated with infections in immunocompromised patients and is rarely implicated in causing severe thrombocytopenia in immunocompetent patients. This article aims to highlight the importance of considering CMV as a significant etiological factor in ITP, particularly in cases of asymptomatic thrombocytopenia.
