Adaptation of an in-vitro digestion model with different zinc-supplementation strategies on nutrient degradation of piglets.

In-vitro studies are widely used in nutrition research. Two major challenges using in-vitro models in animal nutrition research are the individual adaptation of in-vitro digestion models to varying physiological conditions and small digesta output limiting sample material for further analysis. Since several years, the use of zinc in animal production has been legally reduced to control zinc emissions.

Utilization of genetic testing: Analysis of 4,499 prior authorization requests for molecular genetic tests at four US regional health plans.

Continuous advances in genetic testing methodologies and an increased understanding of the genetic mechanisms of diseases have fueled genetic testing utilization across health care specialties. To our knowledge, national trends in the ordering of genetic testing have not been studied broadly across clinical indications, testing methodologies, and ordering provider specialties. We performed a retrospective analysis of 4,499 complete prior authorization requests for molecular genetic testing submitted to four regional health plans' commercial lines of business between May 1, 2019 and May 31, 2019.

Rapid perceptual processing in two- and three-dimensional prostate images.

Radiologists can identify whether a radiograph is abnormal or normal at above chance levels in breast and lung images presented for half a second or less. This early perceptual processing has only been demonstrated in static two-dimensional images (e.g.

Ferumoxytol-Enhanced MR Lymphography for Detection of Metastatic Lymph Nodes in Genitourinary Malignancies: A Prospective Study.

The objective of our study was to evaluate the utility of ferumoxytol-enhanced MR lymphography (MRL) in detection of metastatic lymph nodes (LNs) in patients with prostate, bladder, and kidney cancer. This phase 2 single-institution study enrolled patients with confirmed prostate (arm 1), bladder (arm 2), and kidney (arm 3) cancer and evidence of suspected LN involvement. Participants underwent ferumoxytol-enhanced MRL 24 and 48 hours after IV injection of 7.
