Water soluble nanocurcumin prepared from commercial turmeric powders was compared against ethanol extracted curcumin particles. The oral microflora from five different human volunteers was collected and the efficacy of solvent extracted curcumin versus water extracted nanocurcumin was demonstrated. Nanocurcumin activity against oral microflora confirms its antimicrobial potency. Confocal laser scanning microscopic results revealed the enhanced entry of nanocurcumin particles into microbial cells. The nanosized nature of nanocurcumin appears to have led to increased cellular interaction and thereby efficient destruction of microbial cells in the mouth. In addition, solubility of nanocurcumin is also believed to be a crucial factor behind its successful antimicrobial activity. This study proves that the bioactivity of a compound is greatly influenced by its solubility in water. This work recommends the use of water soluble nanocurcumin (extracted from turmeric) as potent substitute for curcumin in dental formulations.

Effect of microemulsion system on water dispersibility and bioavailability of γ-oryzanol.
Biosci Biotechnol Biochem

Graduate School of Agricultural Science, Tohoku University, Miyagi, Japan.
This study developed water-dispersible γ-oryzanol (WD-OZ) using microemulsion system and assessed their absorption in rats. While γ-oryzanol itself is hardly soluble in water, WD-OZ exhibited high water dispersibility, and γ-oryzanol, along with its metabolites, was detected in rat plasma. These findings provide a solid basis for future application of the microemulsion-based approach to enhance the bioavailability of γ-oryzanol in food.

In recent years, the importance of using local disinfectants instead of systemic antibiotics for the treatment of infectious skin diseases to prevent the emergence of resistant bacteria has become widely recognized. Chlorhexidine gluconate (CHG) is commonly used in veterinary antibacterial shampoos; however, the daily topical application of diluted CHG solutions has also been adopted. Despite its widespread use, few studies have investigated the effects of CHG on the canine skin barrier.

Lutzomyia longipalpis Lutz & Neiva, 1912 (Diptera, Psychodidae), is the primary vector of Leishmania infantum Nicole, 1908, the etiological agent of American visceral leishmaniasis. During their development, sandfly larvae pass through four instars, consuming soil particles enriched with microorganisms and decomposing organic material. In numerous insect species, the intestinal epithelium not only secretes digestive enzymes and absorbs digested nutrients but also carries out additional functions, such as regulating luminal pH and facilitating the absorption or secretion of ions and water.

The study aims to evaluate how bacteriocin and extracellular polymeric substances (EPS) can influence the development of active packaging for food. The components might enhance the performance of packaging materials in terms of their physicochemical properties and their effectiveness in preserving food. Bacteriocin and EPS exert a significant effect in blocking the transmission of UV and visible light radiations.
