Long-term and seasonal evaluation on environmental microbiology and water quality of Shanmei reservoir in southeast China.

As a crucial source of potable water, the quality of water in Shanmei reservoir strongly and directly impacts the safety and well-being of downstream residents. Microorganisms play a pivotal role in the reservoir's resource and energy cycle. However, ecological protection efforts for the Shanmei reservoir have encountered numerous challenges in recent years.

Evaluation of the therapeutic effects of nebulized inhalation of hydrogen-rich water on primary blast lung injury in C57BL/6 mice.

Background: Primary blast lung injury is a common and severe consequence of explosion events, characterized by immediate and delayed effects such as apnea and rapid shallow breathing. The overpressure generated by blasts leads to alveolar and capillary damage, resulting in ventilation-perfusion mismatch and increased intrapulmonary shunting. This reduces the effective gas exchange area, causing hypoxemia and hypercapnia.

Egg white protein under thermal stress: Thermal aggregation orientation and gel properties decline.

This study investigates the effects of varying heat stress temperatures (56 °C to 76 °C) on the gel characteristics of egg white protein. The results indicate that when the heat stress temperature exceeds 60 °C, the textural properties, water-holding capacity, and freeze-thaw stability of egg white gel (EWG) decrease to varying extents compared to untreated EWG. At 76 °C, the proportion of free water in EWG increases from 0.

Ventilation-perfusion matching in early-stage of prone position ventilation: a prospective cohort study between COVID-19 ARDS and ARDS from other etiologies.

Prone positioning is a therapeutic strategy for severe Acute Respiratory Distress Syndrome (ARDS). In COVID-19-associated ARDS (CARDS), the application of prone position has shown varying responses, influenced by factors such as lung recruitability and SARS-CoV-2-induced pulmonary endothelial dysfunction. This study aimed to compare the early impact of pronation on lung ventilation-perfusion matching (VQmatch) in CARDS and non-COVID-19 ARDS patients (non-CARDS).

[Exploring the association between mental stress, lymphocyte subset variations, and coronary lesion severity].

This study aimed to explore the association between perceived mental stress (MS), lymphocyte subset variations, and coronary lesion severity in patients with coronary artery disease (CAD). Patients with CAD were enrolled in this study from September 2023 to May 2024. Perceived Stress Scale-14 (PSS-14) was used to evaluate MS during the last 1 month.
