Ubiquinol (reduced coenzyme Q10) as a metabolic resuscitator in post-cardiac arrest: A randomized, double-blind, placebo-controlled trial.

Introduction: Ubiquinol (reduced coenzyme Q10) is essential for adequate aerobic metabolism. The objective of this trial was to determine whether ubiquinol administration in patients resuscitated from cardiac arrest could increase physiological coenzyme Q10 levels, improve oxygen consumption, and reduce neurological biomarkers of injury.

Materials And Methods: This was a randomized, double-blind, placebo-controlled trial in patients successfully resuscitated from cardiac arrest.

Antifungal hydrogels.

Fungi are increasingly identified as major pathogens in bloodstream infections, often involving indwelling devices. Materials with antifungal properties may provide an important deterrent to these infections. Here we describe amphogel, a dextran-based hydrogel into which amphotericin B is adsorbed.

Alcohol dehydrogenase restricts the ability of the pathogen Candida albicans to form a biofilm on catheter surfaces through an ethanol-based mechanism.

Candida biofilms formed on indwelling medical devices are increasingly associated with severe infections. In this study, we used proteomics and Western and Northern blotting analyses to demonstrate that alcohol dehydrogenase (ADH) is downregulated in Candida biofilms. Disruption of ADH1 significantly (P = 0.

Candida parapsilosis characterization in an outbreak setting.

Candida parapsilosis is an important non-albicans species which infects hospitalized patients. No studies have correlated outbreak infections of C. parapsilosis with multiple virulence factors.

Candida biofilms: antifungal resistance and emerging therapeutic options.

Intravascular catheter infections are a major cause of morbidity and mortality in hospitalized patients, accounting for the majority of the 200,000 nosocomial bloodstream infections occurring in the US annually. Of the intravenous lines that are culture-positive for Candida, 40% actually represent fungemia, which generally necessitates systemic treatment and line removal to affect cure. Until recently, the reason for the need for device removal was unclear.

Mechanism of fluconazole resistance in Candida albicans biofilms: phase-specific role of efflux pumps and membrane sterols.

Candida albicans biofilms are formed through three distinct developmental phases and are associated with high fluconazole (FLU) resistance. In the present study, we used a set of isogenic Candida strains lacking one or more of the drug efflux pumps Cdr1p, Cdr2p, and Mdr1p to determine their role in FLU resistance of biofilms. Additionally, variation in sterol profile as a possible mechanism of drug resistance was investigated.

Differential expression of Candida albicans phospholipase B (PLB1) under various environmental and physiological conditions.

Candida is the fourth most common organism responsible for bloodstream infections in many intensive care units, with Candida albicans being the most predominant species isolated in such cases. It has previously been shown that candidal phospholipase B, encoded by the PLB1 gene, is an important virulence factor for C. albicans pathogenesis.
