Chlorantraniliprole Enhances Cellular Immunity in Larvae of (Smith) (Lepidoptera: Noctuidae).

The innate immunity of insects encompasses cellular and humoral defense mechanisms and constitutes the primary defense against invading microbial pathogens. Cellular immunity (phagocytosis, nodulation, and encapsulation) is primarily mediated by hemocytes. Plasmatocytes and granulocytes play an important role and require changes in the cytoskeletons of hemocytes.

Integrated biomarker-based ecological risks assessment of tadpole responses to tris(2-chloroethyl) phosphate, tris(1-chloro-2-propyl) phosphate, and their combined environmental exposure.

Tris(2-chloroethyl) phosphate (TCEP) and tris(1-chloro-2-propyl) phosphate (TCPP) are common chlorinated organophosphorus flame retardants (OPFRs) used in industry. They have been frequently detected together in aquatic environments and associated with various hazardous effects. However, the ecological risks of prolonged exposure to these OPFRs at environmentally relevant concentrations in non-model aquatic organisms remain unexplored.

Exploring the effects of environmentally relevant concentrations of tris(2-chloroethyl) phosphate on tadpole health: A comprehensive analysis of intestinal microbiota and hepatic transcriptome.

Tris(2-chloroethyl) phosphate (TCEP), a chlorinated organophosphate ester, is commonly found in aquatic environments. Due to its various toxic effects, it may pose a risk to the health of aquatic organisms. However, the potential impacts of TCEP exposure on the intestinal microbiota and hepatic function in amphibians have not been reported.

In this paper, an efficient and reusable catalytic system is developed based on coating magnetic FeO by depositing Fe on the surface of ZnO.

Sublethal effects of chlorantraniliprole on immunity in Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae): Promote encapsulation by upregulating a heat shock protein 70 family gene SfHSP68.1.

As an agricultural pest, the fall armyworm (FAW), Spodoptera frugiperda, poses a severe threat to agriculture in China. Chlorantraniliprole has been widely used to control this pest. In our previous studies, we discovered that LD, LD, and LD chlorantraniliprole promoted encapsulation in the 4th instar larvae of the FAW, with LD chlorantraniliprole having the most significant effect.

Structure, Synthesis, and Bioassays of Sex Pheromone for (Lepidoptera: Crambidae).

The leaf skeletonizer, (Lepidoptera: Crambidae), is a serious insect pest of teak () in China. The application of insect pheromones is widely applied as an environmentally friendly technology for integrated pest management (IPM). In the present study, crude extracts of sex pheromone glands of calling females were collected and then analyzed using gas chromatography/electroantennographic detection (GC/EAD) and gas chromatography-mass spectrometry (GC-MS).

The complete mitochondrial genome of the Baishanzu horned toad (Anura: Megophryidae).

The mitochondrial genome (mitogenome) of (Anura: Megophryidae) was sequenced by the Illumina platform. The assembled circular mitogenome of had a total length of 17,040 bp, with a GC content of 41.25%.

mRNA Turnover Protein 4 Is Vital for Fungal Pathogenicity and Response to Oxidative Stress in .

Ribosome assembly factors have been extensively studied in yeast, and their abnormalities may affect the assembly process of ribosomes and cause severe damage to cells. However, it is not clear whether mRNA turnover protein 4 (MRT4) functions in the fungal growth and pathogenicity in . Here, we identified the nucleus-located gene using reverse genetics, and found that knockdown of resulted in retard mycelia growth and complete loss of pathogenicity.

An adeno-associated virus-mediated immunotherapy for Alzheimer's disease.

Disease-modifying passive immunotherapies focusing on removal of abnormal phosphorylated Tau (p-Tau) constitute promising treatments for Alzheimer's disease (AD). Although several prior immunotherapies targeting p-Tau appear to be beneficial against AD, they have limitations such as the low blood-brain barrier (BBB) penetration rate, short half-life of antibodies, and the likelihood of inflammation. To address these issues, we designed a novel immunotherapy for AD.

LysR-type transcriptional regulator FinR is required for phenazine and pyrrolnitrin biosynthesis in biocontrol Pseudomonas chlororaphis strain G05.

Phenazine-1-carboxylic acid and pyrrolnitrin, the two secondary metabolites produced by Pseudomonas chlororaphis G05, serve as biocontrol agents that mainly contribute to the growth repression of several fungal phytopathogens. Although some regulators of phenazine-1-carboxylic acid biosynthesis have been identified, the regulatory pathway involving phenazine-1-carboxylic acid synthesis is not fully understood. We isolated a white conjugant G05W03 on X-Gal-containing LB agar during our screening of novel regulator candidates using transposon mutagenesis with a fusion mutant G05Δphz::lacZ as a recipient.

An Enzyme-Responsive Prodrug with Inflammation-Triggered Therapeutic Drug Release Characteristics.

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) for relieving inflammatory reactions can lead to severe side effects. It is of great importance to configure new dosing strategies for alleviating the side effects of NSAIDs. In this work, an enzyme-responsive anti-inflammatory prodrug capable of generating indomethacin upon the trigger of inflammation is developed.

Selective Th(iv) capture from a new metal-organic framework with O groups.

Herein we report a new 4-fold interpenetrated metal-organic framework (MOF) functionalized with O groups for selective Th(iv) capture, the activated samples 1a exhibited a high adsorption capacity for pure Th(iv) ions (K = 3.16 × 10 mL g) and the amount of metal ions adsorbed on the adsorbent was 165.61 mg g.

Core-sheath micro/nano fiber membrane with antibacterial and osteogenic dual functions as biomimetic artificial periosteum for bone regeneration applications.

The traditional Chinese medicine icariin (ICA) and broad-spectrum antibacterial drug moxifloxacin hydrochloride (MOX) were introduced into a polycaprolactone core and gelatin shell, respectively, to develop osteogenic and antibacterial biomimetic periosteum by coaxial electrospinning. The physical properties, drug release, degradation, antibacterial property, in vitro and in vivo osteogenesis performances were investigated. Results demonstrated that stepwise and controlled drug release profiles were achieved based on the core-shell configuration and disparate degradation rate of PCL and gelatin.

Icariin-loaded electrospun PCL/gelatin nanofiber membrane as potential artificial periosteum.

Due to the significant role of the periosteum in bone regeneration, we hypothesised that using a specially engineered artificial periosteum could lead to an enhancement in osteogenesis in bone grafts. Herein, we describe our work aimed at fabricating an electrospun fibrous membrane as an artificial periosteum that exhibits flexibility, permeability and osteoinduction. This membrane was designed to cover the complex surface of bone grafts to facilitate and accelerate bone regeneration.

Integration of cell line and process development to overcome the challenge of a difficult to express protein.

This case study addresses the difficulty in achieving high level expression and production of a small, very positively charged recombinant protein. The novel challenges with this protein include the protein's adherence to the cell surface and its inhibitory effects on Chinese hamster ovary (CHO) cell growth. To overcome these challenges, we utilized a multi-prong approach.

The Epitope Recognized by Monoclonal Antibody 2B6 in the B/C Domains of Classical Swine Fever Virus Glycoprotein E2 Affects Viral Binding to Hyperimmune Sera and Replication.

Classical swine fever (CSF) is a highly contagious disease of pigs caused by CSF virus (CSFV). E2 is the major viral envelope protein of immune dominance that induces neutralizing antibodies and confers protection against CSFV infection. The B/C domains of E2 are variable among CSFV isolates, which could affect immunogenicity and binding to antibodies.
