Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Losers and winners: responses of grassland arthropods to land‐use components

open access: yesOikos, EarlyView.
Intensified land‐use in grasslands reduces biodiversity, particularly affecting arthropod populations. However, responses of individual species vary depending on their ecological traits and habitat requirements. Some species may tolerate or even benefit from intensive land‐use, while others, particularly specialists or those with narrow niches, are ...

Modelling environmental effects of agriculture : the case of organic rye and grey partridge [PDF]

open access: yes, 2005
Our optimal control model identifies economic reasons as to why farmland bird populations have dramatically declined in modern agricultural landscapes. By integrating recreational wildlife values into farm level decision-making on arable crop choice and ...

Modifying Antibiotic Activity of Synthetic Thiadiazine Analogs Against MDR Bacteria and ADMET Analysis

open access: yesChemistryOpen, EarlyView.
The study demonstrated that thidiazine compounds potentiated the action of antibiotics. The compounds associated with norfloxacin against S. aureus showed greater significance in relation to the other medications. The indiscriminate use of antibiotics has led to the selection of resistant bacterial strains, significantly reducing the effectiveness of ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Mechanical and Chemical Control of Smooth Cordgrass in Waillapa Bay, Washington [PDF]

open access: yes, 2003
We evaluated four methods to control smooth cordgrass (Spartina alterniflora Loisel), hereafter spartina, in Willapa Bay, Washington: mowing, mowing plus herbicide combination, herbicide only for clones, and aerial application of herbicide for ...

Design, Synthesis, Cytotoxicity Assessment, and Molecular Docking of Novel Triazolopyrimidines as Potent Cyclin‐Dependent Kinase 4 Inhibitors

open access: yesChemistryOpen, EarlyView.
A novel series of 1,5‐dihydro‐[1,2,4]triazolo[4,3‐a]pyrimidines (5a–g) is synthesized and evaluated as potential CDK4 inhibitors. Compounds 5c and 5d exhibit strong cytotoxicity toward HepG2 and MCF‐7 cells with IC50 ≈ 1–2 µM, comparable to doxorubicin.

Comprehensive Insights into Natural Bioactive Compounds: From Chemical Diversity and Mechanisms to Biotechnological Innovations and Applications

open access: yesChemistryOpen, EarlyView.
Natural products derived from plants, animals, fungi, bacteria, and minerals contain diverse bioactive classes such as alkaloids, flavonoids, terpenoids, saponins, tannins, and phenolics. These natural products work through different mechanisms, including ROS inhibition, NF‐κB suppression, and cytokine regulation, and exhibit wide applications across ...
