Introduction: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical.
Objective: To evaluate subjective visual vertical using the bucket method in healthy Brazilian individuals.
Methods: Binocular subjective visual vertical was measured in 100 healthy volunteers, 50 females and 50 males. The volunteers indicated the estimated position in which a fluorescent line inside a bucket reached the vertical position. A total of ten repetitions were performed, five clockwise and five counterclockwise. Data were tabulated and analyzed statistically.
Results: It was observed that the highest concentration of absolute values of vertical deviation was present up to 3°, regardless of gender, and the vertical deviation did not increase with age. The analysis of the mean of the absolute values of deviations from the vertical of 90% of the sample showed a maximum value of 2.6°, and at the analysis of 95%, the maximum value was 3.4° deviation from the vertical.
Conclusion: The bucket method is easy to perform and interpret when assessing the deviation of the subjective visual vertical in relation to the true vertical in healthy Brazilian individuals.

Background: Motor imagery (MI) plays an important role in brain-computer interfaces, especially in evoking event-related desynchronization and synchronization (ERD/S) rhythms in electroencephalogram (EEG) signals. However, the procedure for performing a MI task for a single subject is subjective, making it difficult to determine the actual situation of an individual's MI task and resulting in significant individual EEG response variations during motion cognitive decoding.
Methods: To explore this issue, we designed three visual stimuli (arrow, human, and robot), each of which was used to present three MI tasks (left arm, right arm, and feet), and evaluated differences in brain response in terms of ERD/S rhythms.
Efficacy of multi-color near-infrared fluorescence with indocyanine green: A new imaging strategy and its early experience in laparoscopic cholecystectomy.

Background: Near-infrared fluorescence imaging using intravenous indocyanine green (ICG) has a wide range of applications in multiple surgical scenarios. In laparoscopic cholecystectomy (LC), it facilitates intraoperative identification of the biliary system and reduces the risk of bile duct injury. However, the usual single color fluorescence imaging (SCFI) has limitations in manifesting the fluorescence signal of the target structure when its intensity is relatively low.

Visual adaptation to thin or large bodies was found to shift the subjective body normality towards the adapting body shape. Here we investigated the persistency of such adaptation effect by tracking the timecourse of decay of short-term body size adaptation in young healthy Chinese women. Participants adapted to contracted or expanded body images of unfamiliar female volunteers with a top-up paradigm.

Background And Objectives: In the current global health landscape, there is an increasing demand for rapid and accurate assessment of mental states. Traditional assessment methods typically rely on face-to-face interactions, which are not only time-consuming but also highly subjective. Addressing this issue, this study aims to develop a client-server-based, non-contact multimodal emotion and behavior recognition system to enhance the efficiency and accuracy of mental state assessments.

This article presents a series of 11 clinical cases involving patients with nAMD and DME who received loading doses of faricimab and continued ophthalmological observation. Among them, three patients with nAMD and two with DME were treatment-naïve, while the others were switched from alternative therapies to faricimab.
