Dengue is an emerging disease of high impact on human health. Plants are an important source of new antivirals and stands for its biological properties. The aim of this study was to evaluate the cytotoxicity and antiviral activity and elucidate the antiviral mechanism of ethanolic extracts from against dengue virus 2 (DENV-2).

Article Synopsis
  • Thyroid nodules are commonly benign growths that occur more in women and those with iodine deficiency or prior radiation exposure.
  • Treatment for these nodules includes medications, surgery, and thermal ablation (TA), a method using heat to destroy tissue.
  • This study investigates changes in tissue from thyroid nodules treated with TA and aims to differentiate between benign and malignant nodules using advanced techniques like immunohistochemistry.

This study aimed to isolate and characterize native strains from the rhizospheric soil of plants to evaluate their potential as plant growth-promoting rhizobacteria (PGPR). A total of 22 bacterial isolates were obtained and subjected to various biochemical tests, as well as assessments of plant growth-promoting traits such as phosphate solubilization, hydrogen cyanide production, biocontrol properties through antibiosis, and indole acetic production. Genotypic analysis via 16S rRNA gene sequencing and phylogenetic tree construction identified the strains, with one particular strain named SM 33 showing significant growth-promoting effects on seedlings.

Inoculation with rhizobacteria and feeding by herbivores, two types of abiotic stress, have been shown to increase the production of secondary metabolites in plants as part of the defense response. This study explored the simultaneous effects of inoculation with GB03 (a PGPR species) and herbivory by third-instar larvae on essential oil (EO) yield and volatile organic compound (VOC) emissions in plants. The density of glandular trichomes was also examined, given that they are linked to EO production and VOC emission.

Article Synopsis
  • - The research details the full genome sequence of a specific bacterial strain, sp. 62B, found in the root nodules of peanut plants in central Argentina.
  • - The total genome size is 8.15 megabase pairs (Mbp), which is organized into a main chromosome of 7.29 Mbp and a smaller plasmid of 0.86 Mbp.
  • - This study contributes to our understanding of beneficial bacteria associated with peanut plants and their genetic makeup.
