From animal models to human individuality: Integrative approaches to the study of brain plasticity.

Plasticity allows organisms to form lasting adaptive changes in neural structures in response to interactions with the environment. It serves both species-general functions and individualized skill acquisition. To better understand human plasticity, we need to strengthen the dialogue between human research and animal models.

Importance of subsurface water for hydrological response during storms in a post-wildfire bedrock landscape.

Wildfire alters the hydrologic cycle, with important implications for water supply and hazards including flooding and debris flows. In this study we use a combination of electrical resistivity and stable water isotope analyses to investigate the hydrologic response during storms in three catchments: one unburned and two burned during the 2020 Bobcat Fire in the San Gabriel Mountains, California, USA. Electrical resistivity imaging shows that in the burned catchments, rainfall infiltrated into the weathered bedrock and persisted.

Presumptive hepatogenous photosensitization in beef cattle winter grazing a cover crop containing spp. turnips.

Over a period of ~2 wk, 5 adult beef cows developed severe necrotizing skin lesions on the face and neck shortly after being moved to a field with a cover crop of spp. turnips. We describe here the clinical signs, hematology, and serum chemistry results, as well as gross and histopathologic findings, from this outbreak.

Detection of -Specific IgG, IgM and IgA in Sera and Their Relationship to Respiratory Disease in Cattle.

is one of the major causes of bovine respiratory disease in cattle. The organism is the primary bacterium isolated from calves and young cattle affected with enzootic pneumonia. Novel indirect ELISAs were developed and evaluated to enable quantification of antibody responses to whole cell antigens using A1 strain P1148.

The Role of Histopathology in Ruminant Diagnostics.

Histopathology remains an important tool for ruminant disease diagnostic investigations. Some ruminant diseases require histopathology to make a definitive diagnosis. Clinical history, proper tissue sampling and handling, and proper fixation all increase the efficiency of a histopathologic examination and the likelihood of an accurate diagnosis.
