Study on the Synthesis Method of [11C]Methionine Using Molecular Sieve as Desiccant

Korean Journal of Clinical Laboratory Science
[11C]Methionine is used widely for brain tumor diagnosis via positron emission tomography. Moisture generated during the synthesis of [11C]methionine reduces the synthesis yield. Therefore, a desiccant is used to remove moisture.

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 ...

Nanomotion of bacteria to determine metabolic profile

Nanotechnology and Precision Engineering
In addition to their visible motion such as swimming (e.g., with the help of flagella), bacteria can also exhibit nanomotion that is detectable only with highly sensitive instruments, and this study shows that it is possible to detect bacterial ...

Insights into multiscale chemical characterisation for the understanding of berry maturation

OENO One
Among secondary metabolites, phenolic and volatile compounds are major contributors to wine quality. Their quantities in wines will depend on several factors, their concentrations in grapes but also their extraction rates, along with a number of other ...

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.

Optical communications through highly scattering channels using the coherence-rank

APL Photonics
In optical communications, logical bits are encoded in physical degrees-of-freedom (DoFs) of the electromagnetic field. Consequently, optical scattering in a communications channel compromises the information transfer.
