Effect of Adopting a Timothy Hay-based Diet at Weaning or in Adulthood on Urinary Tract Parameters in Strain 13/N Guinea Pigs ().

Type of feed is an important consideration in herbivore colony management, yet limited studies report on the effects of diet on common conditions such as urolithiasis in guinea pigs. Urolithiasis is a well-documented cause of lower urinary tract disease in guinea pigs, with calcium carbonate uroliths reported as the predominant calculi formed in the guinea pig urinary tract. A calcium-rich diet has been suggested as a risk factor for of urolithiasis, with numerous commercially available guinea pig diets formulated for adults avoiding ingredients that are higher in calcium.

When Minutes Matter: A Comparison of Whole Blood Collection Techniques.

Background: Fast and reliable blood collection is critical to emergency walking blood banks (WBB) because mortality significantly declines when blood is quickly administered to a warfighter with hemorrhagic shock. Phlebotomy for WBB is accomplished via either the "straight stick" (SS) or "ruggedized lock" (RL) method. SS comprises a 16-gauge phlebotomy needle connected to a blood collection bag via tubing.

Risk Associated With Autologous Fresh Whole Blood Training.

Fresh whole blood (FWB) is increasingly being recognized as the ideal resuscitative fluid for hemorrhagic shock. Because of this, military units are working to establish the capability to give FWB from a walking blood bank donor in environments that are unsupported by conventional blood bank services. Therefore, many military units are performing autologous blood transfusion training.

Associations among diffusion tensor imaging and neurocognitive function in survivors of pediatric brain tumor: A pilot study.

The purpose of this study was to determine associations among neurocognitive outcomes and white matter integrity in the inferior fronto-occipital fasciculus (IFOF), uncinate fasciculus (UF), and genu of the corpus callosum (gCC) in survivors of pediatric brain tumor and healthy controls (HCs). Eleven survivors (ages 8-16; >2 years post-treatment) and 14 HCs underwent MRI; diffusion tensor imaging tractography (DSI Studio) was used to assess white matter integrity. Participants completed neuropsychological assessment of overall cognitive ability, executive function, processing speed, divided attention, and memory.

Fronto-limbic white matter microstructure, behavior, and emotion regulation in survivors of pediatric brain tumor.

Purpose: After treatment, pediatric brain tumor survivors (PBTS) face emotional and behavioral challenges, perhaps due to tumor or treatment-related changes in brain structures involved in emotion regulation, including those with fronto-limbic connections. We hypothesized that relative to healthy controls (HCs), PBTS would exhibit greater difficulties with behavior and emotional functioning, and display reduced mean fractional anisotropy (mFA) in white matter tracts with fronto-limbic connections including the cingulum bundle (CB), inferior fronto-occipital fasciculus (IFOF), and uncinate fasciculus (UF). We further predicted that mFA would account for variance in the relationship between group and emotional/behavioral outcome.
