Objective: To evaluate the influence of menstrual cycle on auditory and visual reaction times.
Method: This study was conducted on thirty, healthy, regularly menstruating female subjects who were in the age group of 18-25 years. Influence of different phases of menstrual cycle on Auditory Reaction Time (ART) and Visual Reaction Time (VRT) was evaluated by using a portable audiovisual reaction time apparatus.
Result: The statistical tests which were used were ANOVA and Students 't' test, which showed that there were significant increases in ART and VRT during luteal phase, as compared to those in follicular phase.
Conclusion: Changes in ART and VRT during different phases of menstrual cycle could be due to changes in the levels of female sex hormones, which in turn may lead to salt and water retention.

Background: Nonpharmaceutical interventions for coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, during the pandemic altered the epidemiology of respiratory viruses. This study aimed to determine the changes in respiratory viruses among children hospitalized from 2018 to 2023.
Methods: Nasopharyngeal specimens were collected from children aged under 15 years with fever and/or respiratory symptoms admitted to a medical institution in Fukushima Prefecture between January 2018 and December 2023.

Background: Chemical derivatization is a common technique in liquid chromatography-mass spectrometry (LC-MS) metabolomics used to improve the ionizability and chromatographic properties of metabolites in complex biological samples. This process facilitates better detection and separation of a wide array of compounds. The reagent 2-(4-boronobenzyl) isoquinolin-2-ium bromide (BBII), developed as a glucose labeling reagent for matrix-assisted laser desorption/ionization MS, enhances ionization for glucose and other hydroxyl metabolites.

Background: Edible oils are susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs) throughout production, storage, and transportation processes due to their lipophilic nature. The necessity of quantifying PAHs present in complex oil matrices at trace levels, which bind strongly to impurities in oil matrices, poses a major challenge to the accurate quantification of these contaminants. Therefore, the development of straightforward and effective methods for the separation and enrichment of PAHs in oil samples prior to instrumental analysis is paramount to guaranteeing food safety.

Background: The current synthetic strategies for carbon dots (CDs) are usually time-consuming, rely on complicated processes, and need high temperatures and energy. Recent studies have successfully synthesized CDs at room temperature. Unfortunately, most CDs synthesized at room temperature are obtained under harsh reaction conditions, prepared using aromatic precursors, or need a long time to generate.

Background: The precise identification of pathogens responsible for community-acquired pneumonia (CAP) in children is essential for effective treatment. However, the performance of targeted next-generation sequencing (tNGS) in the detection of pathogens associated with CAP in children remains unclear.
Methods: In this study, 216 children diagnosed with CAP were enrolled, and bronchoalveolar lavage fluid (BALF) samples underwent detection through tNGS, culture, and multiplex quantitative polymerase chain reaction (qPCR).
