A simple microdissection technique for obtaining discrete areas from rat brains exposed to microwave irradiation is described and illustrated. Using the atlas of Pellegrino et al. [10] as a guide, stereotaxically defined areas were removed from coronal sections prepared with sectioning stages constructed from microscope slides. The dissection of sixteen discrete regions is shown in photographic and schematic form. This technique may prove useful for examining neurochemical processes in discrete areas of the rat central nervous system and may aid in establishing the distribution of pharmacological and toxicological agents at a neuroanatomical level.

Australian Preferences for Prenatal Screening: A Discrete Choice Experiment Comparing Metropolitan and Rural/Regional Areas.
Appl Health Econ Health Policy
January 2025
Menzies Centre for Health Policy and Economics, Sydney School of Public Health, University of Sydney, Sydney, NSW, Australia.
Background: Non-invasive prenatal testing has the potential to be a useful genetic screening tool in Australia. However, concerns have been raised about its cost, commercial provision, the psychological impacts of the screening process, and disparities in access experienced by rural and regional communities.
Aims: The aims of this study are (1) to estimate Australian preferences for features of prenatal screening; (2) to explore potential variations in preferences between metropolitan and rural/regional communities; (3) to estimate the extent to which respondents are willing to trade-off between attributes, using willingness to pay (WTP) and willingness to wait estimates.
Fractional tackles: leveraging player tracking data for within-play tackling evaluation in American football.

Tackling is a fundamental defensive move in American football, with the main purpose of stopping the forward motion of the ball-carrier. However, current tackling metrics are manually recorded outcomes that are inherently flawed due to their discrete and subjective nature. Using player tracking data, we present a novel framework for assessing tackling contribution in a continuous and objective manner.

Amsterdam UMC Locatie AMC, Amsterdam, The Netherlands.
Objectives: Noninvasive prenatal testing (NIPT) to screen for fetal aneuploidies by analysing cell-free DNA in maternal plasma is available to pregnant women worldwide. In the future, the scope of NIPT could potentially be expanded to the prediction of adverse pregnancy outcomes. The objective of this study was to assess and compare the preferences of pregnant women and obstetric healthcare professionals on this new test purpose of NIPT.

Accurate detection of cardiac arrhythmias is crucial for preventing premature deaths. The current study employs a dual-stage Discrete Wavelet Transform (DWT) and a median filter to eliminate noise from ECG signals. Subsequently, ECG signals are segmented, and QRS regions are extracted for further preprocessing.

Innovation Lab for Policy Leadership in Agriculture and Food Security (PiLAF), University of Ibadan, Ibadan, Nigeria.
Background: Not much is known about hypertension patients' preferences for attributes of public medical facilities in Nigeria and how these preferences influence their choices of medical facilities for treatment. An understanding of what these patients want especially in terms of service delivery could contribute to improved hypertension control.
Objective: This study aimed to determine hypertension patients' preferences for attributes of a public medical facility in Ibadan, Nigeria.
