Marine and freshwater food webs are strongly structured by size-dependent predator−prey interactions. Predator−prey body mass ratios (PPMR) are important parameters in size-based food-web models, but studies evaluating the temporal stability of PPMR or its relationship to predator feeding modes are scant. Using a large data set of predator−prey pairs from...
There is growing evidence that climate and anthropogenic influences on marine ecosystems are largely manifested by changes in species spatial dynamics. However, less is known about how shifts in species distributions might alter predator-prey overlap and the dynamics of prey populations. We developed a general approach to quantify species spatial...
Freeze-drying, or lyophilization, has shown great promise in addressing many of the logistical challenges of storing and preserving red blood cells (RBCs). A crucial part of any RBC lyophilization protocol is the primary drying temperature, which affects the sample drying rate and the dried cake’s ability to form a stable...
Tolerance of adult zebrafish and efficacy of emamectin benzoate and ivermectin in eliminating Pseudocapillaria tomentosa infection were evaluated. In the tolerance study, behavioral changes, fecundity, histopathology, and mortality were evaluated for in-feed administration of emamectin (0.05, 0.10, and 0.25 mg/kg) and ivermectin (0.05 and 0.10 mg/kg). All doses of emamectin...
BACKGROUND: Patients receiving hospice or palliative care often receive antimicrobial therapy; however the effectiveness
of antimicrobial therapy for symptom management in these patients is unknown.
OBJECTIVE: The study’s objective was to systematically review and summarize existing data on the prevalence and
effectiveness of antimicrobial therapy to improve symptom burden among...
Significance: Parasite survival and virulence relies on effective defenses against reactive oxygen and nitrogen species produced by the host immune system. Peroxiredoxins (Prxs) are ubiquitous enzymes now thought to be central to such defenses and, as such, have potential value as drug targets and vaccine antigens. Recent Advances: Plasmodial and...
BACKGROUND: To examine the association between objectively measured light-intensity and moderate-to-vigorous-intensity physical activity (MVPA), sedentary behaviors, and biological markers in a national
sample of U.S. pregnant women, as few studies have examined these relationships among this population.
METHODS: The sample of noninstitutionalized U.S. civilians was selected by a complex, multistage...
Ebola virus causes an acute hemorrhagic fever lethal in primates and rodents. The contribution of host immune factors to pathogenesis has yet to be determined and may reveal efficacious targets for potential treatment. In this study, we show that the interleukin (IL)-10 signaling pathway modulates Ebola pathogenesis. IL-10 [superscript -...
BACKGROUND: Parents play a significant role in shaping youth physical activity (PA). However, interventions targeting PA
parenting have been ineffective. Methodological inconsistencies related to the measurement of parental influences may be a
contributing factor. The purpose of this article is to review the extant peer-reviewed literature related to the measurement...
BACKGROUND: Increasing emphasis in performance-based payment, public reporting, and quality improvement
(QI) has led to widespread interest in measuring and improving the quality of care. By 2014, hospice programs
will be required to report quality data to the federal government or incur financial penalties. With this increased
interest in quality...
