Article Synopsis
- Healthy women show different community state types (CST) of vaginal bacteria, with variations in lactobacilli, while a lack of lactobacilli is linked to vaginal dryness.
- In postmenopausal women, decreased lactobacilli correlates with hormonal changes, and analyzing vaginal smears can help distinguish between different types of atrophy and inflammation, though more research is needed.
Antimicrobial peptides, also known as AMPs, are cationic and amphipathic molecules found in all living organisms, composing part of the defense mechanisms against various pathogens, including fungi, viruses, bacteria, and nematodes. AMPs derived from plants are the focus of this review because they have gained attention as alternative molecules to overcome pathogen resistance as well as new drugs to combat cancer. Plant AMPs are generally classified based on their sequences and structures, as thionins, defensins, hevein-like peptides, knottins, stable-like peptides, lipid transfer proteins, snakins, and cyclotides.

Background: The school community was heavily impacted by the Covid-19 pandemic, especially with the long time of school closures. This study aimed to analyze the seroprevalence of SARS-CoV-2 antibodies and possible factors associated with seropositivity for COVID-19 in teachers and other school staff, and to estimate the fraction of asymptomatic individuals by sex and age group.
Methods: We conducted a serological survey of SARS-CoV-2 infections.
