Ion mobility spectrometers (IMS) are compact devices for extremely sensitive detection of proton and electron affine volatile compounds down to low pptv concentrations within less than a second. The measuring principle requires ionization of the target analyte. Most IMS employ radioactive electron sources, such as 63 Ni or 3 H. These radioactive materials suffer from legal restrictions limiting the fields of application. Furthermore, the electron emission has a predetermined intensity and cannot be controlled or disabled...

Li-Fraumeni syndrome (LFS) is a rare genetic disorder that confers a high risk of developing certain malignancies at a young age. It is caused by germline mutations in the TP53 gene and is typically diagnosed by sequencing this gene in blood cells. The presence of a mutation in approximately half of the DNA reads (allelic fraction of 50%) is an indicator of a germline mutation, such as that in LFS. Clonal hematopoiesis (CH) is an expansion of a hematopoietic clone containing a somatic driver mutation with a low allelic fraction, usually not more than 10% to 20%...

Adoptive immunotherapy is a highly effective strategy for treating many human cancers, such as melanoma, cervical cancer, lymphoma, and leukemia. Here, a novel cell culture technology is reported for expanding primary human T cells for adoptive immunotherapy. T cells are suspended and cultured in microscale alginate hydrogel tubes (AlgTubes) that are suspended in the cell culture medium in a culture vessel. The hydrogel tubes protect cells from hydrodynamic stresses and confine the cell mass less than 400 µm (in radial diameter) to ensure efficient mass transport, creating a cell-friendly microenvironment for growing T cells...

BACKGROUND: Revisional bariatric surgery (RBS) is associated with higher complication rates compared with primary bariatric surgery. Feeding tubes (FTs), including gastrostomy and jejunostomy tubes placed during RBS, may serve as a safety net to provide nutrition when oral intake is contraindicated or limited; however, FTs in this setting have not been well investigated. OBJECTIVES: This study aims to determine complications, use, and duration of FTs placed during RBS...

The importance of the right food source for the survival and reproduction of certain insect species is well documented. In the case of biocontrol agents, this is even more important in order to reach a high predation or parasitation performance. The egg parasitoid Telenomus laeviceps (Förster, 1861) (Hymenoptera: Scelionidae) is a promising candidate for mass release as a biological control agent of the cabbage moth Mamestra brassicae (Linnaeus, 1758) (Lepidoptera: Noctuidae). However, adult T. laeviceps need a sugar-rich food source to increase their parasitation performance and produce a good amount of female offspring...
