Phthalate Metabolites Were Related to the Risk of High-Frequency Hearing Loss: A Cross-Sectional Study of National Health and Nutrition Examination Survey.

Background: Phthalate metabolites are pervasive in the environment and linked to various health issues. This study aimed to investigate the relationship between phthalate metabolites and hearing loss.

Methods: We conducted a cross-sectional study with 1713 participants based on the National Health and Nutrition Examination Survey 2015-2018.

Comprehensive Expression Analysis of the WRKY Gene Family in under Drought and Waterlogging Stresses.

In response to biotic and abiotic stresses, the WRKY gene family plays a crucial role in plant growth and development. This study focused on and involved genome-wide identification of WRKY gene family members, clarification of their molecular evolutionary characteristics, and comprehensive mapping of their expression profiles under diverse abiotic stress conditions. A total of 60 WRKY gene family members were identified, and their phylogenetic classification revealed three distinct groups.

Integrated Laser Additive Manufacturing of α-AlO Nanoparticle-Seeded β/γ' Ni-Al Intermetallic Alloy with Enhanced High-Temperature Oxidation Performance.

The oxidation of β-NiAl at high temperatures leads to the preferential formation of metastable alumina, such as θ-AlO, which exhibits a significantly faster growth rate compared to stable α-AlO. However, our recent research has shown that through the use of the surface-dispersing nanoparticles (NPs) of metal oxides with a hexagonal closed pack (hcp), such as α-AlO, the thermal growth of α-AlO can be facilitated. The present study employed laser additive manufacturing (LAM) to develop an integrated α-AlO NPs surface-seeded two-phase intermetallic alloy comprising brittle β-NiAl and tougher γ'-NiAl, which demonstrated better comprehensive mechanical properties.

[Changes of histology and ultrastructure of otopoint "Stomach" area in rabbits with chronic gastritis].

Objective: To observe the histological and ultrastructural changes of the otopoint "Stomach" (MA-IC) area in chronic gastritis rabbits so as to provide a foundation for auricular acupoint diagnosis and treatment.

Methods: A total of 20 New Zealand rabbits (half male and half female) were randomly and equally divided into control and model groups. The chronic gastritis model was established by gavage of 5% sodium salicylate each day for 5 weeks, while the rabbits of the control group received gavage of clear water at the same volume.

[Impact of subchronic exposure to low-dose nano-nickel oxide on the reproductive function and offspring of male rats].

Objective: To investigate the influence of subchronic exposure to low-dose subchronic nano-nickel oxide (NNO) on the reproductive function of male rats and embryonic development of the pregnant rats.

Methods: Fifty normal healthy male SD rats weighing 180－220 g were randomly divided into five groups of equal number, negative control, 4 mg/ml micro-nickel oxide (MNO), and 0.16, 0.
