Preferential occurrence of fast radio bursts in massive star-forming galaxies.

Fast radio bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favour highly magnetized neutron stars, or magnetars, as the sources, as evidenced by FRB-like bursts from a galactic magnetar, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown.

A Preliminary Phenomenological Exploration of Experiences of the Empty Pelvis Syndrome Derived From a Modified-Delphi: The Price of Survival Following Pelvic Exenteration for Advanced Pelvic Cancer.

Objective: The empty pelvis syndrome (EPS) is common after pelvic exenteration (PE), causing fluid collections, bowel obstruction, perineal sinuses, and fistulas. The best approach to fill the pelvis to mitigate this remains controversial, and the impact of EPS on health-related quality of life (HrQoL) is unknown. This study is the first to begin to explore lived-experiences of EPS complications.

Food Security as Ethics and Social Responsibility: An Application of the Food Abundance Index in an Urban Setting.

High levels of food insecurity signal the presence of disparities and inequities in local food access that have been shown to negatively impact the health and well-being of individuals and communities. Some argue that the lack of healthy, affordable and culturally relevant food within a community represents a troubling social and ethical concern for any society. The current research conducts an assessment of a specific community utilizing the framework outlined by the Food Abundance Index (FAI) scorecard.

Misdirection of regenerating axons and functional recovery following sciatic nerve injury in rats.

Poor functional recovery found after peripheral nerve injury has been attributed to the misdirection of regenerating axons to reinnervate functionally inappropriate muscles. We applied brief electrical stimulation (ES) to the common fibular (CF) but not the tibial (Tib) nerve just prior to transection and repair of the entire rat sciatic nerve, to attempt to influence the misdirection of its regenerating axons. The specificity with which regenerating axons reinnervated appropriate targets was evaluated physiologically using compound muscle action potentials (M responses) evoked from stimulation of the two nerve branches above the injury site.

Resilience of southwestern Amazon forests to anthropogenic edge effects.

Anthropogenic edge effects can compromise the conservation value of mature tropical forests. To date most edge-effect research in Amazonia has concentrated on forests in relatively seasonal locations or with poor soils in the east of the basin. We present the first evaluation from the relatively richer soils of far western Amazonia on the extent to which mature forest biomass, diversity, and composition are affected by edges.
