Biochanin A feed supplementation alters dynamics of trace gas emissions from lamb urine-amended soil.

Sustainable growth in livestock production requires reductions in trace gas emissions on grazing lands. Urine excreta patches are hot spots for accelerated emissions of carbon and nitrogen. Ruminant dietary supplementation with the isoflavone biochanin A (BCA) has been shown to improve cattle weight gain.

Parascaris spp. eggs shedding patterns in juvenile horses.

Parascaris spp. infect foals worldwide and foals typically shed eggs in the feces from about three to six months of age, upon which natural immunity is incurred. High levels of anthelmintic resistance of Parascaris spp.

Development and Calibration of Pressure-Temperature-Humidity (PTH) Probes for Distributed Atmospheric Monitoring Using Unmanned Aircraft Systems.

Small unmanned aircraft systems (UAS) are increasingly being used for meteorology and atmospheric monitoring. The ease of deployment makes distributed sensing of parameters such as barometric pressure, temperature, and relative humidity in the lower atmospheric boundary layer feasible. However, constraints on payload size and weight, and to a lesser extent power, limit the types of sensors that can be deployed.

Misdiagnosis of cerebellar hemorrhage - features of 'pseudo-gastroenteritis' clinical presentations to the ED and primary care.

Background: Early-stage cerebellar hemorrhage can present with nausea or vomiting absent other neurological symptoms or signs, potentially leading to an incorrect diagnosis of gastroenteritis. We sought to determine the frequency of gastroenteritis-like presentations and delayed or missed diagnoses among patients with spontaneous cerebellar hemorrhage.

Methods: This is a retrospective, case-control analysis of atraumatic, primary cerebellar hemorrhages derived from a systematic search of surgical pathology and autopsy databases at two large urban, academic medical centers from 1984 to 2006.

How often is dizziness from primary cardiovascular disease true vertigo? A systematic review.

Objectives: To assess how frequently cardiovascular dizziness is vertigo. Recent studies suggest providers do not consider cardiovascular causes when a patient reports true vertigo (spinning/motion) as opposed to presyncope (impending faint). It is known that cardiovascular disease causes dizziness, but unknown how often such dizziness is vertiginous, as opposed to presyncopal.

Visual hemispatial neglect, re-assessed.

Increased computer use in clinical settings offers an opportunity to develop new neuropsychological tests that exploit the control computers have over stimulus dimensions and timing. However, before adopting new tools, empirical validation is necessary. In the current study, our aims were twofold: to describe a computerized adaptive procedure with broad potential for neuropsychological investigations, and to demonstrate its implementation in testing for visual hemispatial neglect.

Overreliance on symptom quality in diagnosing dizziness: results of a multicenter survey of emergency physicians.

Objective: To assess emergency physicians' diagnostic approach to the patient with dizziness, using a multicenter quantitative survey.

Participants And Methods: We anonymously surveyed attending and resident emergency physicians at 17 academic-affiliated emergency departments with an Internet-based survey (September 1, 2006, to November 3, 2006). The survey respondents ranked the relative importance of symptom quality, timing, triggers, and associated symptoms and indicated their agreement with 20 statements about diagnostic assessment of dizziness (Likert scale).
