pH-Responsive Alginate/Chitosan Gel Films: An Alternative for Removing Cadmium and Lead from Water.

Biosorption, a non-expensive and easy method for removing potentially toxic metal ions from water, has been the subject of extensive research. In this context, this study introduces a novel approach using sodium alginate and chitosan, versatile biopolymers that have shown excellent results as biosorbents. The challenge of maintaining high efficiencies and reuse is addressed by developing alginate/chitosan-based films.

Exploring the protein profile and biological activity of Crotalus molossus venom against E. coli, P. aeruginosa and S. aureus bacteria and T47D breast carcinoma cells.

Mexico has the highest diversity of snake species in the world, following Australia when considering just venomous snakes. Specifically, in Sonora, the second largest state in the country, more than 15 highly venomous species occur, including the northern black-tailed rattlesnake (Crotalus molossus). This specie's venom has not been as thoroughly researched in contrast with other Mexican vipers, nevertheless some studies report its biological activity and even pharmacological potential with antibacterial and cytotoxic activity.

Antimycobacterial Precatorin A Flavonoid Displays Antibiofilm Activity against BCG.

The aim of this study was to evaluate the potential antibiofilm activity of () compounds over BCG ( BCG) as a model for (). We evaluated the antibiofilm activity as the ability to both inhibit biofilm formation and disrupt preformed biofilms (bactericidal) of compounds, which have been previously described as being antimycobacterials against . BCG developed air-liquid interface biofilms with surface attachment ability and drug tolerance.

Conjugated linoleic acid modifies transcriptional cytokine profile and induces early specific secretory IgA response in infected mice.

Objectives: Adaptive immunity is crucial in controlling infection in the intestinal mucosa, and some dietary lipids may improve mucosal immune function. The aim of this study was to evaluate conjugated linoleic acid (CLA) on the Th17/Treg response and secretory IgA production in a model of giardiasis infection.

Materials And Methods: C3H/HeN male mice were infected with 5×10 trophozoites (GS/M-83-H7, ATCC collection).

Molecular Biology, Composition and Physiological Functions of Cuticle Lipids in Fleshy Fruits.

Fleshy fruits represent a valuable resource of economic and nutritional relevance for humanity. The plant cuticle is the external lipid layer covering the nonwoody aerial organs of land plants, and it is the first contact between fruits and the environment. It has been hypothesized that the cuticle plays a role in the development, ripening, quality, resistance to pathogen attack and postharvest shelf life of fleshy fruits.
