Lufenuron affects the fecundity of Panonychus citri by regulating the methyl farnesoate-ponasterone A network.

In insects, the juvenile hormone (JH) and 20-hydroxyecdysone (20E) pathways jointly regulate fecundity, but only methyl farnesoate (MF) and ponasterone A exist in mites. Comparative transcriptomic analysis in Panonychus citri showed that E75B was significantly downregulated when exposed to lufenuron. Knockdown of E75B significantly affects the expression of vitellogenin (Vg), Fushi tarazu factor 1 (Ftz-f1) and juvenile hormone acid O-methyltransferase (JHAMT), reducing fecundity in mites.

Longitudinal assessment of quality of life indicators and prognosis in esophageal cancer patients with curative resection.

Background: The relationship between quality of life and survival outcomes in esophageal cancer patients following curative resection is not well established. This study aimed to longitudinally assess quality of life indicators and their association with overall survival (OS) in these patients.

Methods: A total of 232 patients were included in the study, and their quality of life was prospectively assessed at different time points using the European Organisation for Research and Treatment of Cancer (EORTC) 30-item core quality of life questionnaire (QLQ-C30) and the disease-specific esophageal module (QLQ-OES18).

microRNA maintains nutrient homeostasis in the symbiont-host interaction.

Endosymbionts provide essential nutrients for hosts, promoting growth, development, and reproduction. However, the molecular regulation of nutrient transport from endosymbiont to host is not well understood. Here, we used bioinformatic analysis, RNA-Sequencing, luciferase assays, RNA immunoprecipitation, and in situ hybridization to show that a bacteriocyte-distributed gene (multidrug resistance-associated protein 4) is negatively regulated by a host (aphid)-specific microRNA (miR-3024).

Sublethal and transgenerational effects of lufenuron on the biological traits of Panonychus citri (McGregor) (Acari: Tetranychidae).

The citrus red mite, Panonychus citri (McGregor), is a globally important pest that has developed severe resistance to various pesticides. Lufenuron has been widely used in the control of the related pests in citrus orchard ecosystem. In this study, the susceptibilities of egg, larva, deutonymph and female adult of P.

CYP4CL2 Confers Metabolic Resistance to Pyridaben in the Citrus Pest Mite .

The citrus red mite has developed strong resistance to acaricides. Cytochrome P450 monooxygenases (P450s) can detoxify pesticides and are involved in pesticide resistance in many insects. Here, a pyridaben-resistant strain showed cross-resistance to cyenopyrafen, bifenazate, fenpyroximate, and tolfenpyrad.

Field investigation of non-uniform environment in a Venlo-type greenhouse in Yangling, China.

Non-uniform environmental conditioning has established substantial energy-saving and conditioning effects in residential buildings, however, few studies on the technology applied in greenhouses have been conducted. Semi-enclosed greenhouse development is hindered by energy consumption. To better apply non-uniform environmental conditioning technology in greenhouses, it is necessary to investigate the non-uniform characteristics of field environment parameters.

Effect of Intrathoracic or Cervical Anastomosis After Esophagectomy on Quality of Life.

Purpose: We aimed to perform serial quality-of-life (QoL) evaluations and comparisons in patients after esophagectomy with intrathoracic anastomosis (IA) or cervical anastomosis (CA).

Methods: Between November 2012 and March 2015, patients who underwent esophagectomy with IA or CA for mid-esophageal to distal esophageal or gastroesophageal junction cancer were followed up. QoL was measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) and esophagus-specific questionnaire (EORTC QLQ-OES18) before surgery, at discharge, and at 1, 6, 12, and 24 months after discharge.

Sublethal and transgenerational effects of pyridaben exposure on the fitness and gene expression of Panonychus citri.

Background: Panonychus citri is a globally dominant citrus plant pest mite. Pesticide-induced population resurgence is a concern for mite control. Exposure to sublethal concentrations of pesticides has stimulated reproduction and outbreak risks in many pests.

Comparative efficacy of different combinations of acapella, active cycle of breathing technique, and external diaphragmatic pacing in perioperative patients with lung cancer: a randomised controlled trial.

Background: Acapella plus active cycle of breathing technique (ACBT), external diaphragm pacemaker (EDP) plus ACBT have been shown to facilitate the recovery of functional capacity and lung function in patients suffering from airway obstruction but the efficacy in perioperative patients with lung cancer has not been proven.

Methods: We conducted a three-arm, prospective, randomized, assessor-blinded, controlled trial in patients with lung cancer who underwent thoracoscopic lobectomy or segmentectomy in the department of thoracic surgery, China. Patients were randomly assigned (1:1:1) to receive Acapella plus ACBT, EDP plus ACBT, or ACBT group (control group) using SAS software.

Resistance of Panonychus citri (McGregor) (Acari: Tetranychidae) to pyridaben in China: monitoring and fitness costs.

Background: Panonychus citri is a major citrus pest worldwide. The short life cycle and high reproductive potential of P. citri, combined with heavy acaricide use, have led to high levels of resistance to acaricides, posing a threat to global resistance management programs.

Correlation between depression and intimacy in lung cancer patients and their family caregivers.

Background: Cancer impacts both patients and their family caregivers. This study aimed to explore the interdependence between depression and intimacy in lung cancer patients and their family caregivers, providing the basis for developing a patient-caregiver centered dyadic intervention.

Methods: This cross-sectional study recruited 182 dyads of lung cancer patients and their family caregivers using a convenient sampling.

Effect of the Active Cycle of Breathing Technique on Perioperative Outcome in Individuals With Esophagectomy: A Quasi-Experimental Study.

The effect of active cycle of breathing technique (ACBT) on EC patients has not been well elucidated. In this research, we aim to explore the effect of ACBT on the perioperative outcomes in patients with esophageal carcinoma who underwent esophagectomy. Patients who underwent esophagectomy in an academic institution from December 2017 to July 2019 were included in this study.

Transcription factors CncC and Maf connect the molecular network between pesticide resistance and resurgence of pest mites.

Pesticide resistance and resurgence are serious problems often occurring simultaneously in the field. In our long-term study of a fenpropathrin-resistant strain of Tetranychus cinnabaribus, enhancement of detoxification and modified fecundity mechanisms were both observed. Here we investigate the network across these two mechanisms and find a key node between resistance and resurgence.

Amidase, a novel detoxifying enzyme, is involved in cyflumetofen resistance in Tetranychus cinnabarinus (Boisduval).

Amidase is an important hydrolytic enzyme in detoxification metabolism. Amidase hydrolyzes a wide variety of nonpeptide carbon‑nitrogen bonds by attacking a cyano group or carbonyl carbon. However, little is known about the relationship between amidase and insecticides.

RNAi targeting ecdysone receptor blocks the larva to adult development of Tetranychus cinnabarinus.

RNA interference (RNAi) is a potentially useful pest control method because of its high specificity. Silencing the expression of important RNAi target genes of pests will block important biological processes and reduce pest damage. Ecdysone is a unique arthropod hormone and the ecdysone receptor (EcR) is a key factor in molting pathway.

Functional analysis of four upregulated carboxylesterase genes associated with fenpropathrin resistance in Tetranychus cinnabarinus (Boisduval).

Background: Carboxylesterases (CarEs) are important in pesticide resistance. Four overexpressed CarE genes with inducible character were screened out in fenpropathrin-resistant Tetranychus cinnabarinus, but their functional roles remained to be further analyzed by RNAi and protein expression.

Results: Feeding a single double-stranded (ds)RNA of each of four genes led to gene-specific downregulation of mRNA, decreased esterase activity and diminished resistance in T.
