An egg parasitoid assesses host egg quality from afar using oviposition-induced plant volatiles.

Parasitoids of herbivores exploit inducible plant volatiles to find plants with potential hosts from a distance, whereas at close range they typically use host-derived cues to pinpoint and identify suitable hosts. Here, we show, however, that the egg parasitoid Trichogramma japonicum assesses host egg quality far more efficiently by remotely using oviposition-induced plant volatiles (OIPVs). In olfactometer assays, female T.

Are Exercise Interventions for People With Knee Osteoarthritis Dosed Appropriately to Meet the World Health Organisation's Physical Activity Guidelines?

Objective: This study aimed to determine the number and proportion of exercise interventions within preexisting clinical trials for people with knee osteoarthritis (KOA) that satisfied the World Health Organisation's (WHO) guidelines for physical activity.

A visual cortical-lateral posterior thalamic nucleus circuit regulates depressive-like behaviors in male mice.

Depression, a prevalent psychiatric disorder of ambiguous etiology and high heterogeneity, has been recently linked to the primary visual cortex (V1). However, the precise circuits mediating the impact of V1 on depressive-like behaviors are poorly understood. Here, we demonstrate that the V1, specifically the lateral posterior nucleus of the thalamus (LP)-projecting V1 glutamatergic subpopulation (Glu neurons), shows reduced activity after chronic restraint stress (CRS) in male mice, leading to depressive-like behaviors.

Microglia-Derived Vitamin D Binding Protein Mediates Synaptic Damage and Induces Depression by Binding to the Neuronal Receptor Megalin.

Vitamin D binding protein (VDBP) is a potential biomarker of major depressive disorder (MDD). This study demonstrates for the first time that VDBP is highly expressed in core emotion-related brain regions of mice susceptible to chronic unpredictable mild stress (CUMS). Specifically, the overexpression of microglia (MG)-derived VDBP in the prelimbic leads to depression-like behavior and aggravates CUMS-induced depressive phenotypes in mice, whereas conditional knockout of MG-derived VDBP can reverse both neuronal damage and depression-like behaviors.

Phase-Separated Nano-Antibiotics Enhanced Survival in Multidrug-Resistant Escherichia coli Sepsis by Precise Periplasmic EcDsbA Targeting.

Disulfide bond (Dsb) proteins, especially DsbA, represent a promising but as-yet-unrealized target in combating multidrug-resistant (MDR) bacteria because their precise subcellular targeting through multibarrier remains a significant challenge. Here, a novel heterogenization-phase-separated nano-antibiotics (NCefoTs) is proposed, through the co-assembly of enzyme-inhibiting lipopeptides (ELp component), membrane-recognizing and disrupting lipopeptides (MLp component), and cefoperazone. The self-sorting components of MLp "concentrated island-liked clusters" on the surface of NCefoTs promote the efficient penetration of NCefoTs through the outer membrane.

Simultaneous effect of different chromatographic conditions on the chromatographic retention of pentapeptide derivatives (HGRFG and NPNPT).

Oligopeptides exhibit great prospects for clinical application and its separation is of great importance in new drug development. To accurately predict the retention of pentapeptides with analogous structures in chromatography, the retention times of 57 pentapeptide derivatives in seven buffers at three temperatures and four mobile phase compositions were measured via reversed-phase high-performance liquid chromatography. The parameters ( , , and ) of the acid-base equilibrium were obtained by fitting the data corresponding to a sigmoidal function.

Accumulation and metabolism of pyroxasulfone in tomato seedlings.

Pyroxasulfone (PYS) is an isoxazole herbicide favored for its high activity. However, the metabolic mechanism of PYS in tomato plants and the response mechanism of tomato to PYS are still lacking.

Lymphocyte Membrane- and 12p1-Dual-Functionalized Nanoparticles for Free HIV-1 Trapping and Precise siRNA Delivery into HIV-1-Infected Cells.

Despite the success of small interfering RNA (siRNA) in clinical settings and its potential value in human immunodeficiency virus (HIV) therapy, the rapid clearance and absence of precise delivery to target cells still hinder the therapeutic effect of siRNA. Herein, a new system, which can escape immune recognition, has HIV-1 neutralizing capacity, and the ability to deliver siRNA specifically into HIV-1-infected cells, is constructed by functionalizing siRNA delivery lipid nanoparticles with the lymphocyte membrane and 12p1. The constructed system is shown to escape uptake by the mononuclear phagocyte system.

A Joint Low-Rank and Sparse Method for Reference Signal Purification in DTMB-Based Passive Bistatic Radar.

In a digital terrestrial multimedia broadcasting (DTMB)-based passive bistatic radar (PBR) system, the received reference signal often suffers from serious multipath effect, which decreases the detection ability of low-observable targets in urban environments. In order to improve the target detection performance, a novel reference signal purification method based on the low-rank and sparse feature is proposed in this paper. Specifically, this method firstly performs synchronization operations to the received reference signal and thus obtains the corresponding pseudo-noise (PN) sequences.
