Evaluation of curcumin nanoemulsion effect to prevent intestinal damage.

Curcumin has gained great prominence for the prevention and treatment of inflammatory bowel disease. However, studies have reported the low bioavailability of orally administered curcumin. This work aimed to evaluate the characteristics, stability and effects of a curcumin-carrying nanoemulsion in preventing intestinal damage induced by indomethacin.

Quercetin-loaded chitosan nanoparticles as an alternative for controlling bacterial adhesion to urethral catheter.

Objectives: The present study aimed to assess the antimicrobial and antiadhesion behavior of quercetin-loaded chitosan nanoparticles in Escherichia coli and Staphylococcus aureus multidrug-resistant isolates.

Methods: The ionic gelation method was used to prepare chitosan nanoparticles loaded with quercetin. The antimicrobial and antibiofilm effects were observed by minimum inhibitory concentration (MIC), plate count, crystal violet assay, and the matrix exopolysaccharide dosages.

Comparative Study Of Genetic Diversity, Virulence Genotype, Biofilm Formation And Antimicrobial Resistance Of Uropathogenic (UPEC) Isolated From Nosocomial And Community Acquired Urinary Tract Infections.

Introduction: is a Gram-negative opportunistic human pathogen, which has aroused considerable medical interest for being involved in cases of urinary tract infection.

Aim: Characterize the isolated both in the hospital and in the community.

Methodology: A total of 200 isolated in urine samples from hospital and community were evaluated in biofilm formation assay and hydrophobicity MATS method.
