The purpose of this research was to evaluate chronic stress using physiological parameters. Wistar rats were exposed to sound stress for 14 days. Biosignals were acquired hourly. To develop a fuzzy inference system that can integrate physiological parameters, the parameters of the system were adjusted by the adaptive neuro-fuzzy inference system. Of the training dataset, the input dataset was the physiological parameters from the biosignals and the output dataset was the target values from the cortisol production. Physiological parameters were integrated using the fuzzy inference system, then 24-hour results were analyzed by the Cosinor method. Chronic stress was evaluated from the degree of circadian rhythm disturbance. Suppose that the degree of stress for initial rest period was 1. Then, the degree of stress after 14-day sound stress increased to 131, and increased to 1.47 after the 7-day recovery period. That is, the rat was exposed to 37%increased amount of stress by the 14-day sound and did not recover after the 7-day recovery period.

Background/aims: Early warning scores are simple scores obtained by measuring physiological parameters and have been regarded as useful tools for detecting clinical deterioration. This study aimed to evaluate the impact of early warning scores in predicting in-hospital mortality in critically ill patients readmitted to the surgical intensive care unit.
Methods: The study was conducted at a tertiary referral teaching hospital in South Korea.
Transmantle pressure under the influence of free breathing: non-invasive quantification of the aqueduct pressure gradient in healthy adults.

Background: The pressure gradient between the ventricles and the subarachnoid space (transmantle pressure) is crucial for understanding CSF circulation and the pathogenesis of certain neurodegenerative diseases. This pressure can be approximated by the pressure difference across the aqueduct (ΔP). Currently, no dedicated platform exists for quantifying ΔP, and no research has been conducted on the impact of breathing on ΔP.

Background: In response to iron deficiency and other environmental stressors, cyanobacteria producing siderophores can help in ameliorating plant stress and enhancing growth physiological and biochemical processes. The objective of this work was to screen the potential of Arthrospira platensis, Pseudanabaena limnetica, Nostoc carneum, and Synechococcus mundulus for siderophore production to select the most promising isolate, then to examine the potentiality of the isolated siderophore in promoting Zea mays seedling growth in an iron-limited environment.
Results: Data of the screening experiment illustrated that Synechococcus mundulus significantly recorded the maximum highest siderophore production (78 ± 2%) while the minimum production was recorded by Nostoc carneum (24.

Horticulture Department, Faculty of Agriculture, Fayoum University, Fayoum, 63514, Egypt.
Background: The imbalance between Egypt's water requirements and supply necessitates the use of unconventional water sources, such as treated sewage water (TSW) and agricultural drainage water (ADW), to combat water scarcity. This study investigated the effects of foliar glycine betaine (GB) on vegetative growth parameters, physiological characteristics, photosynthetic pigments, leaf element contents, anatomical leaf structures, and antioxidant activity. The experiment was conducted in two successive seasons (2021/2022 and 2022/2023) using Kapok seedlings irrigated with ADW and TSW at different mixing ratios with normal irrigation water (NIW) (25%, 50%, 75%, and 100%), combined with foliar spraying of GB at concentrations of 0.
