Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Insecticidal activities and mechanism of extracts from neem leaves against Oxya chinensis

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
In this study, neem leaves were successively extracted with petroleum ether, 95% ethanol and water and the insecticidal activities of these extracts against Oxya chinensis larvae were measured. The results showed that 95% ethanol extract gave the highest

The Relationship between chemical constitution and insecticidal activity III : the synthesis of some typical cyclic esters and their insecticidal activity

, 1933
Apparently it is not possible, at this present stage of development, to formulate any rigorus rules correlating chemical constitution with insecticidal action, and in agreement with such inadequate knowledge, it is extremely difficult to predict with any

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

A review of high nature value farming systems in Europe: Biodiversity, ecosystem services, drivers, innovations and future prospects

People and Nature, EarlyView.
Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Fusion proteins with both insecticidal and neomycin phosphotransferase II activity

, 1988
Hybrid proteins consisting of N-terminal fragments of increasing length of a Bacillus thuringiensis insecticidal protein (Bt2) fused to neomycin phosphotransferase II (NPTII) were produced in Escherichia coli.

Omics Insights Into the Effects of Highbush Blueberry and Cranberry Crop Agroecosystems on Honey Bee Health and Physiology

PROTEOMICS, EarlyView.
ABSTRACT Honey bees (Apis mellifera) are vital pollinators in fruit‐producing agroecosystems like highbush blueberry (HBB) and cranberry (CRA). However, their health is threatened by multiple interacting stressors, including pesticides, pathogens, and nutritional changes.
