The zebrafish (Danio rerio) is emerging as a new important species for studying brain mechanisms and its deficits. Focusing on selected CNS disorders (brain cancer, epilepsy and anxiety) and using them as examples, we discuss the value of zebrafish models in translational neuroscience, and their contribution to neuroimaging, circuit-level and...
Recent work has suggested that plants differ in their relative reliance on structural avoidance of embolism versus maintenance of the xylem water column through dynamic traits such as capacitance, but we still know little about how and why species differ along this continuum. It is even less clear how or...
Altar (31º 29’ S, 70º 28’ W) is a large porphyry Cu-(Au-Mo) deposit with associated
epithermal Au-(Ag-Cu) veins located in the Cordillera Principal of SW San Juan Province
(Argentina). Altar is a complex magmatic-hydrothermal system formed from several
magmatic and hydrothermal pulses during the middle-late Miocene. New LA-ICPMS U-Pb
ages...
The objective of this study was to evaluate the presence
of methicillin-resistant Staphylococcus aureus and
coagulase-negative Staphylococcus spp. in bulk tank
milk samples from 288 organic and conventional dairy
farms located in New York, Wisconsin, and Oregon
from March 2009 to May 2011. Due to recent publications
reporting the presence...
Western juniper (Juniperus occidentalis ssp.
occidentalis Hook) encroachment into mountain big sagebrush
(Artemisia tridentata spp. vaseyana (Rydb.) Beetle)
steppe has reduced livestock forage production, increased
erosion risk, and degraded sagebrush-associated wildlife
habitat. Western juniper has been successfully controlled
with partial cutting followed by prescribed burning the next
fall, but the...
Disease control of soilborne pathogens by biological control agents
(BCAs) is often inconsistent under field conditions. This inconsistency
may be partly influenced by pathogen diversity if there is a differential
response among pathogen species and isolates to selected BCAs. The
responses of 148 Pythium isolates obtained from soil at three...
Persistently high youth unemployment is one of the most pressing problems in South Africa. We prospectively analyze an employer wage subsidy targeted at youth, a policy recently enacted by the South African government to address the issue. Recognizing that a credible estimate of the policy's impact requires a model of...
IMPORTANCE: Although children’s media consumption has been one of the most robust risk factors for childhood obesity, effects of specific parenting influences, such as parental media monitoring, have not been effectively investigated.
OBJECTIVES: This study examined the potential influences of maternal and paternal monitoring of child media exposure and children’s...
Polyoxoniobates are exceptional amongst polyoxometalates in that
they can potentially perform base catalysis in water, a process in
which a proton is bonded to an oxo ligand, and a hydroxyl is
released. Catalytic decomposition of chemical warfare agents such
as organofluorophosphates that were used recently in the infamous
civilian attacks...
