Cadmium exposure increases insecticide sensitivity of Sogatella furcifera (Horváth) by decrease the diversity of symbiotic bacteria.

Cadmium (Cd) is a prevalent environmental pollutant in agricultural ecosystems, particularly within paddy ecosystems, is readily absorbed by rice and enter herbivorous insects through the food chain, thereby influencing the implementation of integrated pest management strategies. However, the effect and mechanisms of Cd exposure on the sensitivity of pests in paddy to insecticides remain unclear. Therefore, this study investigated the effects of Cd exposure on the fitness, insecticide sensitivity and symbiotic bacteria of Sogatella furcifera (Horváth) (white-backed planthopper, WBPH).

Gut microbiota trigger host liver immune responses that affect drug-metabolising enzymes.

There is increasing evidence that the intestinal microbiota plays an integral role in disease pathogenesis and treatment. Specifically, the intestinal microbiota significantly influences the pharmacokinetics and pharmacodynamics of orally administered drugs through direct involvement in drug metabolism and, consequently, drug bioavailability. However, the gut microbiota also exerts immunoregulatory effects on the liver-the organ primarily responsible for drug metabolism-thereby indirectly impacting the body's capacity to metabolise and process drugs.

PgRNA closely correlates to cytokine profile in HBeAg-positive pregnant women undergoing prophylactic antiviral intervention.

Mechanism of action of the nucleotide-binding oligomerization domain-like receptor protein 3 inflammasome and its regulation in liver injury.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases.

Dual-angle light scattering spectroscopy for calibration-free measurements of scatterer suspensions.

It can be difficult to employ optical techniques for analyzing biological structures smaller than or comparable to the wavelength of light, such as extracellular vesicles or some types of bacteria. Biological light scattering spectroscopy (LSS), developed to address this problem, has been successfully used for characterizing tissue on cellular and subcellular scales. At the same time, calibration with a reference sample of known optical properties can complicate LSS measurements.

An ultra-narrow-linewidth laser is a core device in fields such as optical atomic clocks, quantum communications, and microwave photonic oscillators. This paper reports an ultra-narrow-linewidth self-injection locked semiconductor laser, which is realized through optical feedback from a high-Q (258 million) Fabry-Perot (FP) cavity constructed with three mirrors, generating an output power of 12 mW. Employing a delay self-heterodyne method based on a signal source analyzer, the phase noise of the laser is -129 dBc/Hz at 100 kHz offset frequency, with an intrinsic linewidth of 3 mHz.

Hydrogen bonded organic framework pores differentially loading triazole for photocatalytic uranium reduction.

Using temperature modulation, two distinct hydrogen bond organic frameworks HOF-C and HOF-K with different pore sizes were synthesized from the same ligands, tris(4-(4-1,2,4-triazole-4-yl)phenyl)amine. The pore size difference prevents TRZ from entering HOF-K, while allowing TRZ to selectively insert into the larger-pored HOF-C to form HOF-C-TRZ. The donor-acceptor (D-A) structure formed in HOF-C-TRZ enhances its photoelectric response and exhibits exceptional uranium reduction under visible light irradiation.
