Physical network regimes of 3D fibrillar collagen networks trigger invasive phenotypes of breast cancer cells.

The mechanical characteristics of the extracellular environment are known to significantly influence cancer cell behavior in vivo and in vitro. The structural complexity and viscoelastic dynamics of the extracellular matrix (ECM) pose significant challenges in understanding its impact on cancer cells. Herein, we report distinct regulatory signatures in the invasion of different breast cancer cell lines into three-dimensional (3D) fibrillar collagen networks, caused by systematic modifications of the physical network properties.

Short-Term Effects of Dietary Protein Supplementation on Physical Recovery in Older Patients at Risk of Malnutrition during Inpatient Rehabilitation: A Pilot, Randomized, Controlled Trial.

It is estimated that about 50% of geriatric rehabilitation patients suffer from sarcopenia. Thereby, malnutrition is frequently associated with sarcopenia, and dietary intake is the main modifiable risk factor. During hospitalization, older adults are recommended to consume more dietary protein than the current recommended dietary allowance of 0.

Development of a synthesis strategy for sulfamethoxazole derivatives and their coupling with hydrogel microparticles.

Sulfonamides were the first synthetic antibiotics broadly applied in veterinary and human medicine. Their increased use over the last few decades and limited technology to degrade them after entering the sewage system have led to their accumulation in the environment. A new hydrogel microparticle based biosensing application for sulfonamides is developed to overcome existing labour-intensive, and expensive detection methods to analyse and quantify their environmental distribution.

Phenotype Switching of Breast Cancer Cells upon Matrix Interface Crossing.

Tumor cell growth, invasion, and metastasis are dependent on the tumor microenvironment. Many studies emphasize a correlation between the material characteristics of the tumor extracellular matrix (ECM) and the invasive properties of tumor cells and even a trigger of tumor aggressiveness. Herein, we report that the previously observed trigger of migration characteristics of MDA-MB-231 breast cancer cells during transmigration across interfaces of two differently porous matrices is strongly correlated with a persistent change in cell invasiveness and aggressiveness.

Comparative Surfaceome Analysis of Clonal Strains with Different Pathogenicity Reveals Strain-Dependent Profiles.

a poultry-specific intestinal protozoan parasite, is histomonosis's etiological agent. Since treatment or prophylaxis options are no longer available in various countries, histomonosis can lead to significant production losses in chickens and mortality in turkeys. The surfaceome of microbial pathogens is a crucial component of host-pathogen interactions.
