Educating Physical Therapist Students in Tobacco Cessation Counseling: Feasibility and Preliminary Outcomes.

Background: Smoking is the leading preventable cause of chronic disease and premature morbidity. People with physical disabilities experience elevated smoking prevalence when compared with their non-disabled peers. The physical therapy profession is dedicated to meeting needs of people with physical disabilities, yet most physical therapists (PT) do not typically provide tobacco cessation interventions.

Tobacco cessation counseling training in US entry-level physical therapist education curricula: prevalence, content, and associated factors.

Background: The US Public Health Service (USPHS) recommends tobacco cessation counseling (TCC) training for all health care professionals. Within physical therapist practice, smoking can have adverse effects on treatment outcomes in all body systems. In addition, people with physical disabilities have a higher smoking prevalence than the general population, creating a strong need for tobacco cessation among physical therapy clientele.

Strong contribution of immigration to local population regulation: evidence from a migratory passerine.

A mechanistic understanding of the dynamics of populations requires knowledge about the variation of the underlying demographic rates and about the reasons for their variability. In geographically open populations, immigration is often necessary to prevent declines, but little is known about whether immigration can contribute to its regulation. We studied the dynamics of a Red-backed Shrike population (Lanius collurio) over 36 years in Germany with a Bayesian integrated population model.

IL-15Rα deficiency leads to mitochondrial and myofiber differences in fast mouse muscles.

The purpose of this study was to determine mitochondrial changes in fast muscles from interleukin-15 receptor alpha knockout (IL-15RαKO) mice. We tested the hypothesis that fast muscles from IL-15RαKO mice would have a greater mitochondrial density and altered internal structure compared to muscles from control mice. In fast muscles from IL-15RαKO mice, mitochondrial density was 48% greater with a corresponding increase in mitochondrial DNA content.

Demographic response to environmental variation in breeding, stopover and non-breeding areas in a migratory passerine.

Demographic rates of migratory species passing through several areas during their annual cycle may be affected by environmental conditions at each of these areas. Recent studies provide evidence that their impact is not necessarily immediate, but can be delayed. We studied survival, reproductive success and arrival date at the breeding grounds of red-backed shrikes Lanius collurio, a trans-Saharan migrant, in relation to weather and vegetation on the breeding grounds, the stopover sites during migration and in the wintering areas.
