In biomedical research, researchers frequently use statistical procedures such as the t-test, standard analysis of variance (ANOVA), or the repeated measures ANOVA to compare means between the groups of interest. There are frequently some misuses in applying these procedures since the conditions of the experiments or statistical assumptions necessary to apply these procedures are not fully taken into consideration. In this paper, we demonstrate the correct use of repeated measures ANOVA to prevent or minimize ethical or scientific problems due to its misuse. We also describe the appropriate use of multiple comparison tests for follow-up analysis in repeated measures ANOVA. Finally, we demonstrate the use of repeated measures ANOVA by using real data and the statistical software package SPSS (SPSS Inc., USA).

Background: Deficits in emotion recognition have been shown to be closely related to social-cognitive functioning in schizophrenic. This study aimed to investigate the event-related potential (ERP) characteristics of social perception in schizophrenia patients and to explore the neural mechanisms underlying these abnormal cognitive processes related to social perception.
Methods: Participants included 33 schizophrenia patients and 35 healthy controls (HCs).

Background: Obstructive sleep apnea syndrome (OSAS) is a prevalent condition characterised by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to disrupted sleep and associated morbidities. Orthognathic surgery (OGS) has been proposed as a treatment option for OSAS, aimed at anatomically repositioning the maxillofacial structures to alleviate airway obstruction. This systematic review and meta-analysis aimed to evaluate the efficacy of OGS in reducing apnea-hypopnea index (AHI) and Epworth Sleepiness Scale (ESS) scores among OSAS patients.

Highly pathogenic avian influenza (HPAI) epizootics have caused repeated mass mortality events among wild birds. The effect of the infection is potentially detrimental for a variety of bird species, including the Peregrine Falcon (). The numbers of wintering and breeding Peregrine Falcons in the Netherlands have recently declined.

The present study proposes an L-shaped coplanar strip dipole antenna for sensing the presence of adulterants in liquid food samples. The proposed antenna dimensions are optimized using ANSYS HFSS, and a prototype is fabricated and validated. The sensing region is optimized based on the current distribution and measured reflection coefficients.
