Abstract This study assessed the intestinal microbiota of juveniles White shrimp Litopenaus vannamei , whose feed was enriched with three probiotic formulations: Streptomyces sp. RL8 (RL8); a mix Lactobacillus graminis and spp. N7 (Lac‐Strep); Bacillus (Bac‐Strep). The analysis performed by sequencing V3 region 16S rRNA gene treated animals control group before after Vibrio parahaemolyticus challenge. After challenge, highest Shannon diversity indexes corresponded to Bac‐Strep (3.94 ± 0.11...

Cells replicate and segregate their DNA with precision. Previous studies showed that these regulated cell-cycle processes were present in the last eukaryotic common ancestor core molecular parts are conserved across eukaryotes. However, some metamonad parasites have secondarily lost components of processing segregation apparatuses. To clarify evolutionary history systems unusual eukaryotes, we generated a genome assembly for free-living Carpediemonas membranifera carried out comparative...

Marine toxins, produced by various marine microorganisms, pose significant risks to both ecosystems and human health. Understanding their diverse structures properties is crucial for effective mitigation exploration of potential as therapeutic agents. This study presents a comparative analysis two hydrophilic lipophilic examining reactivity bioavailability scores. By investigating similarities among these structurally valuable insights into precursors novel drug development can be gained....

Abstract The current study compares the antibacterial activity of zinc oxide nanostructures (neZnO). For this purpose, two bacterial strains, Escherichia coli (ATCC 4157) and Staphylococcus aureus 29213) were challenged in room light conditions with aforementioned materials. Colloidal hydrothermal methods used to obtain quasi‐round quasi‐diamond platelet‐shape nanostructures. Thus, oxygen vacancy (V O ) effects on surface neZnO are also considered assess its activity. characterization was...

Nanodiamonds (ND-COOH) are used as drug delivery systems because of their attractive properties, they allow for optimized transport therapeutic agents in cellular models. Metformin (MET) is a diabetes mellitus therapy and exhibits anti-cancer properties. In this study, dispersed nanodiamonds were functionalized with metformin by directly binding them to 1,6-hexanediol (ND-MET), effects on the cytotoxicity breast ovarian cancer cells evaluated vitro. A simple synthesis ND-MET was performed...

We evaluated the effect of three variables (cryoprotectant temperature, light regime, and time exposure to cryoprotectant) throughout equilibrium period during cryopreservation on viability microalga Chaetoceros calcitrans (Paulsen). For this, cryoprotectant dimethyl sulfoxide (DMSO) at 5% (v/v) was added different temperatures (4, 10, 25oC) before placing microalgae in cryobiological straws for freezing. Once inside straws, microalgal-cryoprotectant suspensions were subjected following...
