Mine Detection Rats: Effects of Repeated Extinction on Detection Accuracy

identification. Accuracy deteriorated quickly in the absence of reinforcement, suggesting that reinforcement is essential. by Amanda Mahoney, Amy Durgin, Alan Poling [ Western Michigan University, APOPO ], Bart ... 67 Amanda Mahoney is a behavioral researcher at APOPO and a doctoral candidate at Western Michigan University (U.S.).

one training method for maintaining quality operational performance and suggest further examination. by Amanda Mahoney, Timothy L. Edwards, Kate Lalonde, Christophe Cox, Bart Weetjens, Tekimiti Gilbert

Cooperative and independent functions of FGF and Wnt signaling during early inner ear development

Background In multiple vertebrate organisms, including chick, Xenopus, and zebrafish, Fibroblast Growth Factor (FGF) and Wnt signaling cooperate during formation of the otic placode. However, in the mouse, although FGF signaling induces Wnt8a expression during induction of the otic placode, it is unclear whether these two signaling pathways functionally cooperate. Sprouty (Spry...

Evaluation of Giant African Pouched Rats for Detection of Pulmonary Tuberculosis in Patients from a High-Endemic Setting

Background This study established evidence about the diagnostic performance of trained giant African pouched rats for detecting Mycobacterium tuberculosis in sputum of well-characterised patients with presumptive tuberculosis (TB) in a high-burden setting. Methods The TB detection rats were evaluated using sputum samples of patients with presumptive TB enrolled in two prospective...
