School Principals’ Perceptions of Students Walking and Bicycling to School

Background. The purpose was to identify presence of restrictive policies, frequency of active commuting to school, beliefs of childhood health and perceived enabling and restrictive factors with regard to students walking/bicycling to school as observed by elementary and middle school principals. Methods. The study used a non-experimental quantitative survey research method. The census consisted of all public and private, elementary and middle schools in three counties in a Midwestern region (n=96). Results. A total of 71 principals completed the survey (74% response rate). Analyses indicated that the actual number of students walking/bicycling to school did not significantly differ between schools with a restrictive policy and schools with no restrictive policy. Overall, the actual number of students walking/bicycling to school was largely underestimated by principals. In addition, principals at schools with higher walking/bicycling rates were significantly more likely to report that students should consider walking/bicycling if residing within one mile, had significantly more enabling environments, and had significantly less restrictive environments

NuMA Overexpression in Epithelial Ovarian Cancer

Highly aneuploid tumours are common in epithelial ovarian cancers (EOC). We investigated whether NuMA expression was associated with this phenomenon

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery
