A novel lncRNA PDG1 targets NADP-ME to modulate TCA cycle and JH in Aspongopus chinensis diapause.

Diapause is essential for insect survival under adverse environmental conditions and plays a crucial role in regulating reproduction. However, the role of long non-coding RNAs (lncRNAs) in this process remains unclear. In this study, we investigated the function of lncRNAs in the diapause of Aspongopus chinensis.

Unraveling the mechanisms underlying the fluorescent probe detection of microcystin-LR and its binding with CT-DNA.

Cyanobacteria blooms are concerning due to algal toxins like microcystin-leucine arginine (MC-LR). Despite progress in detecting MC-LR and understanding its toxic effects, including calf thymus DNA (CT-DNA) damage, the mechanisms for fluorescent probe detection of MC-LR and its binding to CT-DNA are poorly understood. In this study, we designed three fluorescent probes for MC-LR detection.

Polydopamine-assisted ion-mediated hyaluronic acid grafting for effective construction of hemocompatible platform with cancer cell recognition.

Surfaces capable of specific biomolecule recognition are essential for cancer theranostics, biosensing, and tissue engineering. However, current grafting methods, critical for dictating the recognition efficiency and biocompatibility of biomaterials, especially hydrophilic polymers, struggle to balance high grafting density with ease of implementation. In pursuit of a simple, effective, and versatile solution, we introduced a polydopamine (PDA)-assisted Ca-mediated grafting strategy using hyaluronic acid (HA) as a model material.

Deciphering intricate associations between vigorous development and novel metabolic preferences of partial denitrification/anammox granular consortia within mainstream municipal wastewater.

There is limited understanding of the granular partial denitrification/anammox (PD/A) microbiota and metabolic hierarchy specific to municipal wastewater treatment, particularly concerning the multi-mechanisms of functional differentiation and granulation tendencies under high-loading shocks. Therefore, this study utilized fragmented mature biofilm as the exclusive inoculum to rapidly establish a granular PD/A system. Following long-term feeding with municipal wastewater, PD/A process reached a total nitrogen removal efficiency of 97.

Virulence expression difference to intestinal cells of different pathogenic Listeria monocytogenes contaminating sausages after simulated digestive tract.

This study investigated the difference in survival among Listeria monocytogenes (LM) 10403S (highly pathogenic strain) and M7 (low pathogenic strain) in sausage under a simulated digestive environment, and established intestinal organoids and macrophages co-culture model to further explore the virulence expression difference to intestinal cells between LM 10403S and M7 after in vitro gastrointestinal digestion. Results showed that, compared with LM M7, LM 10403S exhibited a high survival rate during in vitro digestion, which may be due to the increased expression of stress response-related genes. In addition, the expression of virulence genes in LM 10403S was significantly higher than in LM M7 under the gastrointestinal environment.

Prediction of p-phenylenediamine antioxidant concentrations in human urine using machine learning models.

p-phenylenediamine antioxidants (PPDs) are extensively used in rubber manufacturing for their potent antioxidative properties, but PPDs and 2-anilino-5-[(4-methylpentan-2yl)amino]cyclohexa-2,5-diene-1,4-dione (6PPDQ) pose potential environmental and health risks. Existing biomonitoring methods for assessing human exposure to PPDs are labor-intensive, costly, and provide limited data. Thus, there is a critical need to develop predictive models for evaluating PPDs and 6PPDQ exposure levels to facilitate health risk assessments.

Establishment of a novel large-scale targeted metabolomics method based on NFSWI-DDA mode utilizing HRMS and TQ-MS.

Metabolites identification is the major bottleneck in untargeted LC-MS metabolomics, primarily due to the limited availability of MS information for most detected metabolites in data dependent acquisition (DDA) mode. To solve this problem, we have integrated the iterative, interval, and segmented window acquisition concepts to develop an innovative non-fixed segmented window interval data dependency acquisition (NFSWI-DDA) mode, which achieves comparable MS coverage to data independent acquisition (DIA) mode. This acquisition strategy harnesses the strengths of both DDA and DIA, which could provide extensive coverage and excellent reproducibility of MS spectra.

Design of magnetic polyethyleneimine-fluorescein isothiocyanate composites toward efficient enrichment of phosphopeptides.

Phosphoproteins maintain the normal metabolic activity of the organisms. Direct phosphopeptides detection is difficult to be realized by mass spectroscopy (MS) due to the low ionization efficiency, low abundance of phosphopeptides and interferences of complicated biological fluids. In the present work, a magnetic composite material was prepared by combining polyethyleneimine (PEI) and fluorescein isothiocyanate (FITC) focusing on phosphopeptides enrichment.

Chicken adipose tissue is differentially involved in primary and secondary regional immune response to NDV through miR-20a-5p-NR4A3 pathway.

The mammalian adipose tissue (AT) plays a key role in regulating immune function and anti-infective protection to maintain tissue regional homeostasis. However, it is still unclear whether there are differences in the participation of AT in primary and secondary immune response, and whether avian AT has the similar immune function characteristics to mammals. In this study, we used Newcastle disease virus (NDV) attenuated vaccine to induce primary and secondary immune response in chickens, and the changes of the key regulatory gene NR4A3 (nuclear receptor subfamily 4 group A member 3) of T cells activation and its targeted miR-20a-5p were detected by quantitative real-time PCR (qRT-PCR).

Widely targeted metabolomics analysis reveals dynamic changes in metabolites of 'Hass' avocado during postharvest ripening period.

Avocado (Persea americana Mill) is a climacteric fruit harvested at the green stage that ripens postharvest to become edible. The 'Hass' cultivar, known for its rich, buttery flavor and pear-shaped appearance, was studied for metabolite changes during postharvest ripening using UPLC-MS/MS approach. The 16-day ripening period could be divided into three stages: evolution (days 1-9), edible ripe (days 10-15) and overripe (day 16).
