Article Synopsis
  • Cyanobacteria produce secondary metabolites that can act as biopesticides, making them valuable for sustainable farming practices.
  • The study examined the antifungal properties of two co-isolated cyanobacterial strains, Nostoc muscorum and N. linckia, alongside their fungal partners against several plant pathogens.
  • Results indicated that while the cyanobacterial cultures showed antifungal activity against some fungi, the effectiveness often depended on the co-isolated fungal partner, emphasizing the need for precise culturing methods in future research.

Article Synopsis
  • Seaweed-derived bioproducts, like Kelpak®, offer a sustainable method for managing crops, particularly under stress conditions like salinity.
  • The study identified specific bioactive phlorotannins in the seaweed Ecklonia maxima, such as eckol and dibenzodioxin-fucodiphloroethol, which showed beneficial effects on tomato seedlings facing salt stress.
  • Treatment with Kelpak® improved overall plant health by boosting antioxidant levels and reducing damage, highlighting its enhanced effectiveness compared to individual phlorotannins due to its additional bioactive compounds.

Planar gated blood pool (GBP-P) radionuclide imaging is a valuable non-invasive technique for assessing left ventricular ejection fraction (LVEF). Serial cardiac imaging can be performed to monitor the potential decline in LVEF among patients undergoing cardiotoxic chemotherapy. Consequently, accurate LVEF determination becomes paramount.

Smoke-water (SW) and Karrikinolide1 (KAR) release dormancy and improve seed germination in many plant species. Therefore, we tested SW (1:2500 /) and KAR (10 M) to break the morphological dormancy of celery cultivar ( L.).
