Background/objectives: This research investigates brain connectivity patterns in reaction to social and non-social stimuli within a virtual reality environment, emphasizing their impact on cognitive functions, specifically working memory.

Methods: Employing the LEiDA framework with EEG data from 47 participants, I examined dynamic brain network states elicited by social avatars compared to non-social stick cues during a VR memory task. Through the integration of LEiDA with deep learning and graph theory analyses, unique connectivity patterns associated with cue type were discerned, underscoring the substantial influence of social cues on cognitive processes.

2-Thiohydantoin derivatives, including different substitutions at N-1 and C-5 (5-methyl-, 5-isopropyl-, 1-acetyl-5-methyl-, and 1-acetyl-5-isopropyl-) (1-4, respectively), were synthesized by the known literature methods. In these synthetic pathways, it was reported that enantiomerically pure 2-thiohydantions were obtained in the absence of any solvent via the reaction of L-amino acids with thiourea (1&2) and via the reaction of L-amino acids with NHSCN and acetic anhydride (3&4). However, in this study, in contrary to the previous literature studies, racemic mixtures of 2-thiohydantoins were obtained although the same synthetic methods were used.

Objective: This study utilized three cell lines: normal prostate epithelial RWPE-1, androgen-dependent LNCaP, and androgen-independent PC3. We investigated the inhibitory effects of phenylboronic acid (PBA)'s inhibitory effect on cellular proliferation due to its ability to disrupt microtubule formation in prostate cancer cell lines. Additionally, this study aimed to assess the cytotoxic effects of PBA on prostate cancer cells using twodimensional (2D) and three-dimensional (3D) cell culture models.
