A simple molecular method to identify and quantify genera of gastrointestinal nematodes of cattle.

Classic approaches for antemortem identification of gastrointestinal nematodes (GIN) require coproculture of eggs and morphological examination. While adequate for diagnosis, many PCR techniques cannot easily quantify mixed infections without controls and/or standard curves. Herein, we developed a simple and rapid test for differentiating and quantifying mixed infections of GIN using PCR products separated by capillary electrophoresis.

Mediates Early Host Immune Responses via Macrophage and Toll-Like Receptor Pathways.

is an abomasal parasite with significant economic impact on the cattle industry. Early host immune responses are poorly understood. Here, we examined time course expression of Toll-like receptors (TLRs) in peripheral blood mononuclear cells (PBMC) during infection where PBMC macrophages (Mϕ) generated both pro- and anti-inflammatory responses when incubated with excretory/secretory products (ESP) from fourth-stage larvae (OoESP-L4) or adult worms (OoESP-Ad).

Initial analysis of copy number variations in cattle selected for resistance or susceptibility to intestinal nematodes.

Genomic structural variation is an important and abundant source of genetic and phenotypic variation. We report an initial analysis of copy number variations (CNVs) in cattle selected for resistance or susceptibility to intestinal nematodes. We performed three array comparative genomic hybridization (CGH) experiments to compare Angus cattle with extreme phenotypes for fecal egg count and serum pepsinogen level.

Prediction of return to productivity after severe traumatic brain injury: investigations of optimal neuropsychological tests and timing of assessment.

Objectives: (1) To examine predictive validity of global neuropsychological performance, and performance on timed tests (controlling for manual motor function) and untimed tests, including attention, memory, executive function, on return to productivity at 1 year after traumatic brain injury (TBI). (2) To compare predictive validity at 8 weeks versus 5 months postinjury. (3) To examine predictive validity of early degree of recovery (8wk-5mo postinjury) for return to productivity.

Recovery of cognitive function after traumatic brain injury: a multilevel modeling analysis of Canadian outcomes.

Objective: To ascertain patterns of cognitive recovery during the first year after traumatic brain injury (TBI). Specifically, differential recovery across cognitive domains was investigated.

Design: Prospective, longitudinal, naturalistic, 1-year follow-up study.

Impact of wheeled seated mobility devices on adult users' and their caregivers' occupational performance: a critical literature review.

The prescription of wheeled seated mobility devices for clients with mobility impairment is a growing area in occupational therapy practice. The goal is to enhance client participation in occupation through technical intervention. This critical review examines the body of knowledge concerning the impact and effectiveness of the provision of wheeled seated mobility on the occupational performance of wheelchair users and their caregivers.
