Summary: Dioryctria abietella is a destructive forest pest that interacts with host plants and insecticides through odorant binding proteins. Two OBPs have strong interactions with plant volatiles and insecticides, which can be used for the control of D. abietella. Additionally, these two OBPs may be associated with insecticide resistance.

Summary: In this study, 14 OBP genes were identified from the antennae transcriptomes and genomic data of S. guani for the first time. The expression profiles of these genes showed that SguaOBP2/5/6/11/12/13 were specifically highly expressed in the female antennae. Ligand binding assays revealed that SguaOBP12 had high binding affinity with several chemical compounds, while SguaOBP11 demonstrated high or medium binding affinity with them. Molecular docking and RNAi experiments further explored the molecular interactions and behavioral functions of SguaOBP11 and SguaOBP12 with these odor molecules.

Summary: In this study, the odorant binding protein (OBP) gene family in Dioryctria abietella was investigated. Expression profiles showed that most OBPs were highly expressed in the antennae of females. Two DabiOBPs were isolated from the antennae and exhibited different odorant response spectra. Molecular simulations revealed key residues involved in the interactions of DabiOBPs and ligands. This study highlights the olfactory roles of antennal DabiOBPs in D. abietella and helps in the identification of potential behavioral compounds for pest control.

Summary: This study investigated the function and binding properties of two general odorant binding proteins (GOBPs) in Spodoptera frugiperda. It was found that SfruGOBP1 had binding affinities to a few volatiles and insecticides, while SfruGOBP2 showed a broader ligand-binding spectrum, suggesting its importance in perceiving host volatiles. Molecular docking and site-directed mutagenesis assays provided insight into the key amino acid residues involved in the binding of insecticides to the GOBPs. This study offers valuable information for understanding the olfactory mechanism of GOBPs in S. frugiperda.

Summary: Understanding the chemical recognition of Ophraella communa for Ambrosia artemisiifolia can enhance its biological control effect. In this study, OcomOBP7 was cloned and the tissue expression and binding ability were analyzed, revealing the involvement of OcomOBP7 in the chemical recognition of A. artemisiifolia by O. communa. These findings lay a theoretical foundation for the development of attractants for O. communa and contribute to the better biological control of A. artemisiifolia.

Summary: Meteorus pulchricornis is a parasitic wasp that preys on various lepidopteran pests. The use of broad-spectrum insecticides poses a serious threat to the olfactory recognition of nontarget insects like parasitoid wasps. In this study, the researchers discovered that the MpulOBP6 protein exhibited strong binding affinity to three insecticides, and the hydrophobic interaction was the primary driving force in the formation and stabilization of MpulOBP6-insecticide complexes. The findings have significant implications for understanding the impact of insecticide use on the olfactory recognition of nontarget insects in agricultural production.

Summary: Spodoptera frugiperda is a worldwide generalist pest with remarkable adaptations to environments and stresses, including diverse feeding preferences, mate seeking, and pesticide resistance. This study identified and analyzed the expression patterns of odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) in S. frugiperda across developmental stages and sexes. The results revealed correlations between gene expression patterns and phylogenic trees, and suggested the potential function of SfruOBP31 in food, mate seeking, and pesticide resistance.

Summary: Spider mites, major agricultural pests, have been found to possess a new class of odorant-binding proteins (OBPs) which differ from those of insects. The OBPs in T. urticae show unique characteristics in terms of their conserved cysteines and three-dimensional protein folding.

Summary: This study discovered that MaltOBP12 has binding affinities to 9 pine volatiles and revealed the structure and protein-ligand interaction mechanism through modeling and molecular docking. These findings not only help us understand how odorant-binding proteins flexibly bind odorants, but also promote the screening of behaviorally active compounds through computer methods to prevent M. alternatus.

Summary: By synthesizing novel anthraquinone derivatives, compound 1c was found to exhibit highly active larvicidal activity against Culex quinquefasciatus mosquito larvae, with stronger binding energy than the control permethrin. This suggests that compound 1c may be a more potent inhibitor for mosquito larvae.

Summary: This study aimed to demonstrate whether a new prototype implantable artificial bronchus (IAB) can release trapped air from the lungs of recently deceased patients with emphysema. By mechanically ventilating seven deceased patients and measuring ventilation parameters and fraction of inspired oxygen before and after IAB placement, it was found that IAB implantation significantly reduced respiratory system plateau pressure and intrinsic positive end-expiratory pressure in most patients with emphysema. These findings provide a basis for further clinical studies on the safety and efficacy of IAB in patients with emphysema and its short- and long-term effects.

Summary: This study compared the end-expiratory transpulmonary pressure between fixed and individualized positive end-expiratory pressure (PEEP) strategies in superobese patients and analyzed their effects on respiratory mechanics, end-expiratory lung volume, gas exchange, and hemodynamic parameters. The study found that individualized PEEP strategy resulted in lower end-expiratory transpulmonary pressure while improving respiratory mechanics, lung volume, and oxygenation. Therefore, individualized PEEP strategy may be a feasible approach for respiratory support in superobese patients undergoing laparoscopic surgery.

Summary: Respiratory diseases pose significant health concerns worldwide, with high morbidity and mortality rates and considerable burdens on patients. Despite advances in understanding the pathologic mechanisms, current therapies for severe respiratory diseases are predominantly supportive and cannot improve lung function or reverse tissue remodeling. Mesenchymal stromal cells (MSCs) have shown promise in promoting immunomodulation, tissue repair, and other therapeutic properties in experimental models, but have had limited efficacy in early-stage clinical trials. Functional enhancement strategies, such as genetic engineering and preconditioning methods, have emerged to enhance the therapeutic actions of MSCs and improve clinical outcomes. This review discusses various strategies investigated in experimental settings to potentiate the therapeutic properties of MSCs for respiratory diseases, including changes in culture conditions, exposure to inflammatory environments, pharmacological agents, and genetic manipulation.
