Exploring the Potential of Nitrofurantoin for Infection Control in Regenerative Endodontics: In Vitro Study.

Introduction: This study assessed a new antimicrobial paste formulation containing nitrofurantoin for regenerative endodontics against multispecies biofilms.

Methods: Four groups of 11 single-root teeth each were tested: Negative control group (brain-heart infusion broth + micro-organisms); Hoshino 1 conventional tri-antibiotic paste group (1:1:1 ratio); Hoshino 5 group (5:5:5 ratio); Experimental group with nitrofurantoin, ciprofloxacin, and metronidazole. Minimum inhibitory concentrations of each antimicrobial were determined.

A new automated solar disc for water disinfection by pasteurization.

A new automated Solar Water Pasteurization Disc of double reflection of 3.8 and 1.3 m in diameter for the first and second reflectors has been erected and tested for performing microbiological disinfection of water in a simple, efficient, and continuous treatment in Brazil.

In Vitro Anti-Toxoplasma gondii and Antimicrobial Activity of Amides Derived from Cinnamic Acid.

Most cinnamic acids, their esters, amides, aldehydes, and alcohols present several therapeutic actions through anti-inflammatory, antitumor, and inhibitory activity against a great variety of microorganisms. In this work, eight amines derived from cinnamic acid were synthesized and tested against host cells infected with and the bacteria and three strains of . Compounds and showed the best result against intracellular , presenting antiparasitic activity at low concentrations (0.

V H+-ATPase along the yeast secretory pathway: energization of the ER and Golgi membranes.

H+ transport driven by V H+-ATPase was found in membrane fractions enriched with ER/PM and Golgi/Golgi-like membranes of Saccharomyces cerevisiae efficiently purified in sucrose density gradient from the vacuolar membranes according to the determination of the respective markers including vacuolar Ca2+-ATPase, Pmc1::HA. Purification of ER from PM by a removal of PM modified with concanavalin A reduced H+ transport activity of P H+-ATPase by more than 75% while that of V H+-ATPase remained unchanged. ER H+ ATPase exhibits higher resistance to bafilomycin (I50=38.

A 2S albumin-homologous protein from passion fruit seeds inhibits the fungal growth and acidification of the medium by Fusarium oxysporum.

Antimicrobial proteins have been isolated from a wide range of plant species. More recently, it has become increasingly clear that these types of proteins play an important role in the protection of plants. In this study, we investigate the presence of defense-related proteins from passion fruit (Passiflora edulis f.
