The Burkholderia cenocepacia iron starvation σ factor, OrbS, possesses an on-board iron sensor.

Burkholderia cenocepacia is an opportunistic pathogen that causes severe infections of the cystic fibrosis (CF) lung. To acquire iron, B. cenocepacia secretes the Fe(III)-binding compound, ornibactin.

Physiological Significance of Discrimination on Stress Markers, Obesity, and LDL Oxidation among a European American and African American Cohort of Females.

Background: Factors underlying physiological reactions from perceived discrimination and its relation to adverse health outcomes are not completely understood. The main purpose of this study was to test the hypothesis that experiences of discrimination (recent and lifetime) correlate with biomarkers of stress, oxidative stress, and obesity among adult females.

Method: Data on 62 females who self-identify as African American (AA; n = 31) or European American (EA; n = 31) aged 21-45 years were included.

The immediate efficacy of inhaled nitric oxide treatment in preterm infants with acute respiratory failure during neonatal transport.

Aim: The aim of our review was to describe the clinical response to inhaled nitric oxide (iNO) in a series of preterm babies in respiratory failure during uplift transfers to a neonatal intensive care unit.

Methods: We performed a retrospective review of critical newborns with gestational age <34  weeks transferred from January 2013 to December 2018. Data were extracted from our Clinical Information System for transport.

[The transformation to environmentally sustainable health systems: The National Health Service example in England].

This article provides insight from the Sustainable Development Unit, a top down policy, monitoring and delivery unit to support a large complex health system, the National Health Service, to embed sustainable development. The dedicated unit nurtured and supported bottom up action through top down change, it translated legal requirements, embedded good governance and engaged with stakeholders.By identifying a specific and manageable topic area the unit created an entry point to broader change and enabled action, in this case the unit started with carbon footprinting and reduction.

Environmental sustainability and travel within the dental practice.

A significant amount of dentistry's carbon emissions originate from travel (64.5%). Dental-associated travel affects air quality, releasing over 443 tonnes of nitrogen oxides (NOx) and 22 tonnes of particulate matter (PM2.
