Quality and efficiency of apple orchard protection affected by sprayer type and application rate

Spanish Journal of Agricultural Research, 2013
The goal of this work was to evaluate the potential of reduced application rates in apple trees as well as the potential of selective spray applications by using sensor-based tree detection techniques in Serbian fruit production.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Cana-de-açúcar: avaliação da taxa de aplicação e deposição do herbicida glifosato Sugarcane: evaluation of application rates and deposition of the glyphosate herbicide

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
No Brasil, o uso de agrotóxicos consumirá, anualmente, mais de seis milhões de m3 de água como veículo, na cultura da cana-de-açúcar. O menor volume de calda aumenta a autonomia e a capacidade operacional dos pulverizadores, diminuindo o risco de perdas ...
