Sulfur Diffusion Studies Imitating Recycled Ground-Rubber-Containing Compounds.

In-rubber properties of vulcanizates deteriorate in the presence of incorporated recycled ground rubber (GR). This behavior is partly explained by a possible diffusion of sulfur from the rubber matrix into the GR. Therefore, the sulfur concentration and, thus, the crosslink density in the matrix are reduced.

An Integrated Model of Heat Transfer in Meat Products during Multistage Operations.

This work focuses on the modelling of the heat transfer in the key processes during the manufacturing of salted-smoked loin pork, a traditional Danish product called "Hamburgerryg". Drying, smoking, steam-cooking, water-cooling, and air-cooling processes are important process steps in the production of "Hamburgerryg". A mathematical model that describes the heat transfer during these processes was developed.

Immunohistochemical analyses of paraffin-embedded sections after primary surgery or trimodality treatment in esophageal carcinoma.

Background: The microscopic tumor extension before, during or after radiochemotherapy (RCHT) and its correlation with the tumor microenvironment (TME) are presently unknown. This information is, however, crucial in the era of image-guided, adaptive high-precision photon or particle therapy.

Materials And Methods: In this pilot study, we analyzed formalin-fixed paraffin-embedded (FFPE) tumor resection specimen from patients with histologically confirmed squamous cell carcinoma (SCC; n = 10) or adenocarcinoma (A; n = 10) of the esophagus, having undergone neoadjuvant radiochemotherapy followed by resection (NRCHT + R) or resection (R)].

Diagnostic value of chest radiography in the early management of severely injured patients with mediastinal vascular injury.

Introduction: Time is of the essence in the management of severely injured patients. This is especially true in patients with mediastinal vascular injury (MVI). This rare, yet life threatening injury needs early detection and immediate decision making.

Cellular plasticity upon proton irradiation determines tumor cell radiosensitivity.

Proton radiotherapy has been implemented into the standard-of-care for cancer patients within recent years. However, experimental studies investigating cellular and molecular mechanisms are lacking, and prognostic biomarkers are needed. Cancer stem cell (CSC)-related biomarkers, such as aldehyde dehydrogenase (ALDH), are known to influence cellular radiosensitivity through inactivation of reactive oxygen species, DNA damage repair, and cell death.
