Published: September 2001

A series of insecticidal dihydropyrazoles and related compounds have been shown to exhibit negative cross-resistance to a resistant (super-kdr) strain of houseflies with site-insensitivity to pyrethroids. The level of cross-resistance is similar to that observed previously for a range of N-alkylamides against the same strain.

Background: Intravitreal injections, a relatively recent treatment in ophthalmology, is being adopted rapidly worldwide and becoming one of the most common therapies in the field. Numerous complications are associated with this treatment, ranging from minor inflammatory ailments to endophthalmitis. We analyzed the conjunctival flora of patients treated with intravitreal injections and topical antibiotics.

The risk of neonicotinoid insecticides to honeybees is a global issue. Cycloxaprid (CYC) is a novel neonicotinoid insecticide with outstanding activities, good safety profiles, and no cross-resistance with other neonicotinoids. Information on the environmental risks of CYC is limited, especially its effects on honeybees.

Quaternary ammonium compounds (QACs) served as broad spectrum antimicrobial agents are widely applied for surface disinfection, skin and mucous disinfection, and mouthwash. The daily applications of QACs have significantly increased, especially during the COVID-19 pandemic. However, the environmental residues of QACs have demonstrated harmful impacts on the environment, leading to an increase in environmental contamination, resistant microbes and disruption of microecology.

Although silver is known for its antibacterial activity, its exact mode of action remains unclear. In our previous work, we described AgNbO nanoparticles (AgNbO NPs) prepared using a ceramic method, followed by high-energy and low-energy ball-milling processes, which exhibited antimicrobial activity with negligible release of Ag in deionized water. Here, we investigated thoroughly the mode of action of these AgNbO NPs against .

The intersection of the HER2-low subtype with endocrine resistance: the role of interconnected signaling pathways.

Article Synopsis
  • Endocrine therapy targeting the estrogen receptor alpha (ERα) has been successful for treating estrogen receptor positive (ER+) breast cancer since the 1970s, but most patients eventually develop resistance, particularly in metastatic cases.
  • Resistance often stems from genetic changes in the estrogen receptor, the MAP kinase pathway, or transcription factors, with mutations in HER2 leading to total resistance against multiple therapies.
  • Recent studies suggest a link between endocrine-resistant tumors and the HER2-low subtype, indicating a need for more research into the signaling networks in HER2-low tumors that could be targeted to overcome resistance.
