Making a Case for Faculty Advisor-Advisee Concordant Pairs.

The Accreditation Council for Pharmacy Education Standards require schools and colleges of pharmacy to provide the needed resources for student success, including student advising. The faculty advisor's role in schools and colleges of pharmacy can be varied and may include modeling professional behavior, serving as students' advocate, and providing academic and professional guidance. This is especially important upon students entering pharmacy school when the risk of being overwhelmed has been documented.

Adsorptive exchange of coccolith biominerals facilitates viral infection.

Marine coccolithophores are globally distributed, unicellular phytoplankton that produce nanopatterned, calcite biominerals (coccoliths). These biominerals are synthesized internally, deposited into an extracellular coccosphere, and routinely released into the external medium, where they profoundly affect the global carbon cycle. The cellular costs and benefits of calcification remain unresolved.

Temperate infection in a virus-host system previously known for virulent dynamics.

The blooming cosmopolitan coccolithophore Emiliania huxleyi and its viruses (EhVs) are a model for density-dependent virulent dynamics. EhVs commonly exhibit rapid viral reproduction and drive host death in high-density laboratory cultures and mesocosms that simulate blooms. Here we show that this system exhibits physiology-dependent temperate dynamics at environmentally relevant E.

Waves cue distinct behaviors and differentiate transport of congeneric snail larvae from sheltered versus wavy habitats.

Marine population dynamics often depend on dispersal of larvae with infinitesimal odds of survival, creating selective pressure for larval behaviors that enhance transport to suitable habitats. One intriguing possibility is that larvae navigate using physical signals dominating their natal environments. We tested whether flow-induced larval behaviors vary with adults' physical environments, using congeneric snail larvae from the wavy continental shelf () and from turbulent inlets ().

Turbulence induces metabolically costly behaviors and inhibits food capture in oyster larvae, causing net energy loss.

Planktotrophic invertebrate larvae require energy to develop, disperse and settle successfully, and it is unknown how their energetics are impacted by turbulence. Ciliated larvae gain metabolic energy from their phytoplankton food to offset the energetic costs of growth, development and ciliary activity for swimming and feeding. Turbulence may affect the energetic balance by inducing behaviors that alter the metabolic costs and efficiency of swimming, by raising the encounter rate with food particles and by inhibiting food capture.

Directional flow sensing by passively stable larvae.

Mollusk larvae have a stable, velum-up orientation that may influence how they sense and react to hydrodynamic signals applied in different directions. Directional sensing abilities and responses could affect how a larva interacts with anisotropic fluid motions, including those in feeding currents and in boundary layers encountered during settlement. Oyster larvae (Crassostrea virginica) were exposed to simple shear in a Couette device and to solid-body rotation in a single rotating cylinder.

Hydrodynamic sensing and behavior by oyster larvae in turbulence and waves.

Hydrodynamic signals from turbulence and waves may provide marine invertebrate larvae with behavioral cues that affect the pathways and energetic costs of larval delivery to adult habitats. Oysters (Crassostrea virginica) live in sheltered estuaries with strong turbulence and small waves, but their larvae can be transported into coastal waters with large waves. These contrasting environments have different ranges of hydrodynamic signals, because turbulence generally produces higher spatial velocity gradients, whereas waves can produce higher temporal velocity gradients.

Biophysical constraints on optimal patch lengths for settlement of a reef-building bivalve.

Reef-building species form discrete patches atop soft sediments, and reef restoration often involves depositing solid material as a substrate for larval settlement and growth. There have been few theoretical efforts to optimize the physical characteristics of a restored reef patch to achieve high recruitment rates. The delivery of competent larvae to a reef patch is influenced by larval behavior and by physical habitat characteristics such as substrate roughness, patch length, current speed, and water depth.

Active downward propulsion by oyster larvae in turbulence.

Oyster larvae (Crassostrea virginica) could enhance their settlement success by moving toward the seafloor in the strong turbulence associated with coastal habitats. We characterized the behavior of individual oyster larvae in grid-generated turbulence by measuring larval velocities and flow velocities simultaneously using infrared particle image velocimetry. We estimated larval behavioral velocities and propulsive forces as functions of the kinetic energy dissipation rate ε, strain rate γ, vorticity ξ and acceleration α.

Family burden in bipolar disorders: results from the Italian Mood Disorders Study (IMDS).

Aims: To explore: a) the burden of care, and the professional and social support in relatives of patients with bipolar disorders; b) the psychosocial interventions provided to patients and their families by Italian mental health centres.

Methods: 342 outpatients with a bipolar disorder and their key-relatives were randomly recruited in 26 Italian mental health centres, randomly selected and stratified by geographical area and population density. Family burden was explored in relation to: a) patient's clinical status and disability; b) relatives' social and professional support; c) interventions received by patients and their families; d) geographical area.
