Effects of palm olein and palm stearin on cecal and fecal microbiota of C57BL/6J mice under low and high fat intakes.

This work aimed to study the effects of dietary lipid composition and content on cecal and fecal microbiota of mice fed the following diets for 8 weeks: palm olein (PO)-based low-fat diet, PO-based high-fat diet, palm stearin (PS)-based low-fat diet, and PS-based high-fat diet. Increasing the dietary PS level favored the growth of Firmicutes over Bacteroidetes in the cecum and feces. In addition, it significantly elevated the total lipid (p < 0.

The Efficacy of Breast Implant Irrigant Solutions: A Comparative Analysis Using an In Vitro Model.

Background: Infections are challenging complications of implant-based breast reconstruction and augmentation. They pose a clinical challenge, with significant economic implications. One proposed solution is implant irrigation at the time of placement.

The Arginine Deiminase Pathway Impacts Antibiotic Tolerance during Biofilm-Mediated Streptococcus pyogenes Infections.

Bacterial biofilms are responsible for a variety of serious human infections and are notoriously difficult to treat due to their recalcitrance to antibiotics. Further work is necessary to elicit a full understanding of the mechanism of this antibiotic tolerance. The arginine deiminase (ADI) pathway is responsible for bacterial pH maintenance and is highly expressed during biofilm growth in multiple bacterial species.

-Transgenic BALB/c Mice as a Model of Pseudomonas aeruginosa Infections of the Cystic Fibrosis Lung.

The opportunistic pathogen is responsible for much of the morbidity and mortality associated with cystic fibrosis (CF), a condition that predisposes patients to chronic lung infections. lung infections are difficult to treat because adapts to the CF lung, can develop multidrug resistance, and can form biofilms. Despite the clinical significance of , modeling infections in CF has been challenging.

Intraoperative Tobramycin Powder Prevents Enterobacter cloacae Surgical Site Infections in a Rabbit Model of Internal Fixation.

Objectives: To evaluate the efficacy of intraoperative tobramycin powder in preventing surgical site infection (SSI) and implant colonization with Enterobacter cloacae in a rabbit fixation model. Gram-negative rods, particularly Enterobacter species, comprise an increasing percentage of SSI at our institution.

Methods: Eighteen New Zealand White rabbits underwent surgical fixation of the left tibia with implantation of a plate and screws.
