Are horned cows in loose housing more stressed than hornless cows? a cross-sectional study in organic dairy farms.

In commercial dairy farming, the majority of cows are dehorned or genetically hornless. It is argued that this reduces the risk of injurious and stressful social conflicts. On the other hand, in horned herds, management and housing may be better adapted to the cows, e.

Psychobabble: A Preliminary Study of the Novel Educational Game to Teach Psychiatric Interviewing Techniques.

Objective: This article details a novel intervention for teaching psychiatric interviewing techniques implemented at McGovern Medical School at UTHealth Houston.

Methods: Forty medical students played the newly developed educational game Psychobabble to enhance their assessment of auditory hallucinations. Pre-session and post-session surveys assessed students' inquiry methods, competence, training relevance, and exercise efficacy.

Conversion of a laboratory-based test for phenylalanine detection to a simple paper-based format and implications for PKU screening in low-resource settings.

Laboratory-based testing does not reach many individuals in lower-resource settings who could benefit from access to appropriate tests for diagnosis and therapy. A critical issue is laboratory-based testing often requires an environment with a high level of resources and supporting infrastructure that is not available in many areas of the world. The current report describes the conversion of a laboratory-based test for phenylalanine detection to a simple paper-based test appropriate for use in low-resource settings.

Progress in the development of paper-based diagnostics for low-resource point-of-care settings.

This Review focuses on recent work in the field of paper microfluidics that specifically addresses the goal of translating the multistep processes that are characteristic of gold-standard laboratory tests to low-resource point-of-care settings. A major challenge is to implement multistep processes with the robust fluid control required to achieve the necessary sensitivity and specificity of a given application in a user-friendly package that minimizes equipment. We review key work in the areas of fluidic controls for automation in paper-based devices, readout methods that minimize dedicated equipment, and power and heating methods that are compatible with low-resource point-of-care settings.

Dissolvable bridges for manipulating fluid volumes in paper networks.

A capability that is key to increasing the performance of paper microfluidic devices is control of fluid transport in the devices. We present dissolvable bridges as a novel method of manipulating fluid volumes within paper-based devices. We demonstrate and characterize the operation of the bridges, including tunability of the volumes passed from 10 μL to 80 μL, using parameters such as geometry and composition.
