In this research, we fabricated a sensitive monoclonal antibody (mAb) 2C3 that targeted etomidate (ET) and metomidate (MT) to establish a lateral-flow immunoassay (LFIA) that incorporated fluorescent microsphere sensors, enabling both the qualitative and quantitative detection of ET and MT within 10 min. Analysis indicated that the visual colorimetric values for ET and MT in water samples were 0.3 μg kg, respectively, with quantitative detection ranges of 0.

Rice (), a globally significant staple crop, is crucial for ensuring human food security due to its high yield and quality. However, the intensification of industrial activities has resulted in escalating cadmium (Cd) pollution in agricultural soils, posing a substantial threat to rice production. To address this challenge, this review comprehensively analyzes rice promoters, with a particular focus on identifying and characterizing key -regulatory elements (CREs) within them.

While tumor organoids have revolutionized cancer research by recapitulating the cellular architecture and behaviors of real tumors in vitro, their lack of functional vasculature hinders their attainment of full physiological capabilities. Current efforts to vascularize organoids are struggling to achieve well-defined vascular networks, mimicking the intricate hierarchy observed in vivo, which restricts the physiological relevance particularly for studying tumor progression and response to therapies targeting the tumor vasculature. An innovative vascularized patient-derived tumor organoids (PDTOs)-on-a-chip with hierarchical, tumor-specific microvasculature is presented, providing a versatile platform to explore tumor-vascular dynamics and antivascular drug efficacy.

For patients undergoing long-term peritoneal dialysis (PD), exposure to biologically incompatible PD solutions and the consequent peritoneal structure change can lead to progressive angiogenesis and fibrosis, and ultimately result in ultrafiltration failure (UFF). Peritoneal transport studies in aquaporin 1 (AQP1) knockout mice indicate that water transport across the peritoneum is mediated by AQP1, which accounts for up to 50% of ultrafiltration. Another recent study on a large cohort of PD patients with kidney failure further substantiated the impact of AQP1 genotype variation on water channel expression in the peritoneal membrane, influencing water transport, ultrafiltration, and patient prognosis.

Ochratoxins (OTs, including OTA, OTB, and OTC), exhibit nephrotoxicity, carcinogenicity, teratogenicity, and immunotoxicity, contaminating wheat, maize, and rice, so endangering human health. In this study, we designed and screened haptens using computational chemistry to prepare mAb 4G11, which simultaneously recognized OTA, OTB, and OTC with high sensitivity and specificity. We developed a fluorescent microsphere immunochromatographic assay (FMIA), which could detect the total amount of OTs with a visual detection limit of 0.

Most molecules and dielectric materials have characteristic bond vibrations or phonon modes in the mid-infrared regime. However, infrared absorption spectroscopy lacks the sensitivity for detecting trace analytes due to the low quantum efficiency of infrared sensors. Here, we report mid-infrared photothermal plasmonic scattering (MIP-PS) spectroscopy to push the infrared detection limit toward nearly a hundred molecules in a plasmonic nanocavity.

Due to the characteristics of long-term persistence, leading to extensive temporal and spatial distribution of the environmental pollutant dibutyl phthalate (DBP), analyzing of a large number of food and environment samples over a long period and at a high frequency must be necessary. It is of great significance to construct a simple, rapid, sensitive and high-throughput immunoassay method. For the first time, 8 different DBP hapten molecules were designed using computer simulation to provide DBP epitope informations from both conformation and electrostatic aspects for the target molecule.

Cerium dioxide nanoparticles (CeO NPs) have enzyme-like properties and scavenge excess ROS induced by stressors such as drought. However, the underlying molecular mechanisms by which CeO NPs enhance drought resistance are unknown. In this work, both foliar application and soil injection of CeO NPs were used to rice seedlings under a 30 day moderate drought (40% soil relative moisture).

Amyloid-β (Aβ) is considered a primary therapeutic target for Alzheimer's disease (AD). However, just eliminating Aβ in patients with AD has exhibited restricted clinical efficacy, possibly failing to address the metabolic abnormalities caused by AD, such as insulin resistance. To address this concern, our research has employed two types of macrocyclic amphiphiles, guanidinium-modified calixarene and cyclodextrin coassembly (GCD), as delivery systems for insulin.

Article Synopsis
  • Multiple myeloma (MM) is a serious blood cancer with an increasing patient population, and the role of Zinc finger protein 655 (ZNF655) in its progression is not well understood.
  • This study examined how decreasing ZNF655 levels affected MM cell traits and tumor growth, using various lab techniques to measure changes in cell behavior.
  • The results showed that reducing ZNF655 significantly decreased MM cell growth, halted the cell cycle, and triggered cell death, suggesting that targeting ZNF655 may offer a new way to treat MM through its effects on AKT activation.

A silver-catalyzed cascade cyclization strategy has been developed for the synthesis of 4-aminotetrahydrocarbazole, a common core structure found in various alkaloids. This target molecule can be synthesized through a one-step tandem cyclization reaction, thereby eliminating the need for a prior synthesis of tetrahydrocarbazole. Furthermore, the use of chiral -butylsulfinamide facilitates chiral resolution of the resulting product.
