Cerebral small vessel disease (SVD) contributes to approximately 50% of human dementias world-wide and pose a burden the health care system worldwide. Early endothelial/blood-brain barrier (BBB) dysfunction is an important contributor pathogenesis SVD. Sphingosine-1-phosphate (S1P), membrane-derived signaling sphingolipid, regulates BBB integrity by binding its receptor isoform 1 (S1PR1) on endothelial cells. We previously showed that activation S1PR1 using SEW2871, selective agonist,...
Quantifying organismal sensitivity to heat stress provides one means for predicting vulnerability climate change. Birds are ideal investigating this approach, as they display quantifiable fitness consequences associated with behavioural and physiological responses stress. We used a recently developed method that examines correlations between readily‐observable behaviours air temperature (T ) investigate interspecific variation in avian seasonally hot, arid regions on three continents: the...
The application of stable isotope analysis (SIA) to the fields ecology and animal biology has rapidly expanded over past three decades, particularly with regards water analysis. SIA now provides opportunity monitor migration patterns, examine food webs, assess habitat changes in current study systems. While carbon nitrogen biological samples have become common, analyses oxygen or hydrogen are used more sparingly despite their promising utility for tracing sources metabolism. Common...
Abstract During the long‐distance migratory flights of birds, lean mass breakdown occurs in concert with fat catabolism and is expected to have repercussions on total stopover duration because birds require time rebuild tissue before accumulating reserves. Despite this, little known about role in‐flight direct measurements are restricted by destructive nature traditional body composition analysis technological limitations tracking small over large expanses. We used non‐lethal, non‐invasive...
Nestlings of many bird species are hosts to hematophagous ectoparasites. Parasitism nestlings is usually sub‐lethal, but its effects can extend into the fledgling and adult stages. Nestling lose enough blood become anemic, reduced oxygen‐carrying capacity on metabolic rate poorly understood. This study examined consequences parasitism by larval blow flies Protocalliphora sialia for nestling tree swallows Tachycineta bicolor . We found that with more parasites had higher whole‐animal RMR....
Songbirds meet the extreme metabolic demands of migration by burning both stored fat and protein. However, catabolizing these endogenous tissues for energy leads to organ atrophy, reductions in gastrointestinal tissue can be as great 50% pre-flight mass. Remarkably, during stopover refuelling birds quickly regain digestive mass performance. Aminopeptidase-N (APN) is a brush-border enzyme responsible late-stage protein digestion may critically assist reconstruction stopover, thus compensating...
Summary Background There is currently a high demand for concurrent system of skin rejuvenation accompanying rhtidectomy. CO 2 laser treatment prior to surgical ablative reduction has produced promising results, but the adjunct service at time surgery never been reviewed. Objectives Determine effects rhytides and evidence aging in with correction followed by fractional application. Methods During study from September 2008 February 2009 treat patients who have underwent short flap rhytidectomy...
Endothelial dysfunction and blood-brain barrier (BBB) leakage have been suggested as a fundamental role in the development of cerebral small vessel disease (SVD) pathology. However, molecular cellular mechanisms that link hypoxic hypoperfusion BBB disruption remain elusive. Sphingosine-1-phosphate (S1P) regulates integrity by binding to its receptor isoform 1 (S1PR<sub>1</sub>) on endothelial cells. This study tested hypothesis triggers capillary S1PR<sub>1</sub> disruption, which...
