is a major cause of chronic respiratory infections in patients with cystic fibrosis (CF), with biofilm formation contributing to its persistence and antibiotic resistance. This study aimed to gain insights into the mechanistic action of succinic acid as a ciprofloxacin adjuvant against clinically relevant CF isolates, including small colony variants and mucoid strains, and a ciprofloxacin-resistant strain grown within CF dense mucus. Time-kill assays in artificial CF mucus, along with planktonic and surface-attached biofilm experiments, were used to assess the activity of succinic acid alone and in combination with sublethal ciprofloxacin concentrations.

White grubs possess natural defense mechanisms against entomopathogenic nematodes (EPNs). Hence, EPN isolates that naturally infect white grubs tend to be among the most effective biological control agents of white grubs. We tested the virulence of four EPN isolates recently isolated from infected white grubs in turfgrass areas in central New Jersey, USA against third-instar larvae of , , and , which are pests of turfgrass and ornamental plants in the northeastern USA.

Stem cells are capable of self-renewal and differentiation into various specialized cells, making them a potential therapeutic option in regenerative medicine. This study establishes a comprehensive methodology for isolating, culturing, and characterizing rat hair follicle stem cells. Hair follicles were harvested from Sprague-Dawley rats and subjected to two different isolation techniques.

Objective: The objective of this review will be to evaluate the effect of prior aspiration versus non-aspiration during intramuscular injection on the occurrence of adverse effects in adult patients.

Introduction: Aspiration is a procedure conducted prior to the administration of intramuscular medications that aims to ensure that the needle tip is inserted in the proper place. Although aspiration is a common procedure, questions have been raised about adverse effects.
