The invasive white-backed planthopper (WBP) poses a severe threat to global rice crop security, and most populations have developed significant resistance to neonicotinoids. Although these species remain sensitive to mesoionic triflumezopyrim (TFM), both neonicotinoids and TFM are hazardous to pollinating insects. Herein, we disclose a series of new spirocompounds designed via isosteric ring replacement of scaffold hopping.

Mesoionic insecticides have emerged as promising pest nAChR modulators devoid of cross-resistance with neonicotinoids, demonstrating exceptional efficacy against sap-feeding insects. Nevertheless, the tetrahydrothiazolo[3,2-]pyrimidine structure remains underexplored within this chemotype. Here, we report an indole-based scaffold hopping of tetrahydrothiazolo[3,2-]pyrimidine, which leads to the development of a series of novel mesoionics.

The selectivity of pesticides for harmful insects versus beneficial organisms has long been a critical issue in agriculture. Pyrido-[1,2-] pyrimidine mesoionics have been widely demonstrated to effectively control a diverse range of insect pests. However, many of their analogues have exhibited high toxicity to bees.

Given the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (Her-2) in triple-negative breast cancer (TNBC) cells, the efficacy of targeted therapies is limited. In this study, we uncovered that triptolide (TP) effectively suppresses the migration and invasiveness of MDA-MB-231 cells by activating autophagic pathways. Western blotting analysis revealed that TP significantly reduced the expression levels of p62 protein, while simultaneously markedly increasing the expression levels of LC3B-II, BNIP3, BNIP3L, ATG5, and ULK1 proteins, strongly suggesting an enhancement of autophagic activity in the cells.

Aim(s): This study aims to evaluate the workload of clinical nurses by measuring the work relative value (work RVU) of common nursing items based on the resource-based relative value scale in China.

Background: Various single measurements have been employed to measure the nursing workload, but no comprehensive method has yet to be developed in China.

Methods: A descriptive study was conducted to construct a common item set for nursing work in general wards on the basis of the 2019 History Information System nursing database from Class A tertiary hospitals to identify the time associated with each service.

Article Synopsis
  • Mature rapeseed pods often shatter during harvest, causing significant yield losses that can range from 8-12% up to 50% under adverse conditions, highlighting the need for better resistance strategies.
  • The research emphasizes the complexity of pod shatter as it is influenced by genetics, environment, agronomic practices, and harvesting techniques, suggesting that future studies should consider these interconnected factors.
  • A literature review identified strategies to improve rapeseed yields through breeding more shatter-resistant varieties, optimizing cultivation practices, and utilizing advanced technologies in mechanized harvesting.

The pesticide application method is one of the important factors affecting its effectiveness and residues, and the risk of pesticides to non-target organisms. To elucidate the effect of application methods on the efficacy and residue of cyenopyrafen, and the toxic effects on pollinators honeybees in strawberry cultivation, the efficacy and residual behavior of cyenopyrafen were investigated using foliar spray and backward leaf spray in field trials. The results showed that the initial deposition of cyenopyrafen using backward leaf spray on target leaves reached 5.
