Abstract The possibility of associative learning in plants is a topic of ongoing controversy. In one published study, growing pea plants were reported to associate two stimuli (airflow and light) and thereafter use one (airflow) as an indicator for the other (light), similar to dogs in Pavlov’s famous experiments. However, this observation could not be independently repeated. Here we examine a possible reason for the failure of a published reproduction attempt, which used substantially different light quality during plant cultivation prior to experimental treatments than in the original study. This could have resulted in dramatically different More >

Abstract Introduction: Tumor grade plays a critical role in the management of papillary non-invasive urothelial carcinoma (UC). Since grading of UC relies on morphologic criteria, variability in interpretation exists among pathologists. The objective of this study was to examine inter-observer variability in the grading of papillary non-invasive UC at a single academic medical center.
Materials and methods: One general pathologist and two genitourinary pathologists were blinded to patient identity and graded 98 consecutive UC specimens using the 1973 and 2004 classification systems. Kappa statistics (κ) were used to measure inter-observer reproducibility to account for agreement expected purely by… More >

Abstract Introduction: To assess the accuracy of sonouroflow (SUF), an at-home, wireless-based acoustic system for recording lower urinary tract symptoms (LUTS) and urinary flow rate, and to compare test-to-test variability in flow parameters recorded using this new portable method with those obtained by conventional uroflowmetry.
Materials and methods: An initial pilot study evaluated the technical feasibility of the SUF system. Subsequently, test-to-test variability was compared between sonourograms (SUFm) and standard uroflowmetry recordings. Uroflowmetry tests were performed at the urology office at pre-set times. SUF tests were performed at home on a schedule in keeping with the subjects' normal habits.
