Junctional Adhesion Molecule-C Mediates the Recruitment of Embryonic-Endothelial Progenitor Cells to the Perivascular Niche during Tumor Angiogenesis [PDF]

open access: yes, 2020
The homing of Endothelial Progenitor Cells (EPCs) to tumor angiogenic sites has been described as a multistep process, involving adhesion, migration, incorporation and sprouting, for which the underlying molecular and cellular mechanisms are yet to be ...

In Vitro Techniques for the Assessment of Neurotoxicity

open access: yesEnvironmental Health Perspectives, 1998
Risk assessment is a process often divided into the following steps: a) hazard identification, b) dose-response assessment, c) exposure assessment, and d) risk characterization. Regulatory toxicity studies usually are aimed at providing data for the first two steps.

Comparative Evaluation of Three Preprocessing Methods for Extraction and Detection of Influenza A Virus Nucleic Acids from Sputum

open access: yesFrontiers in Medicine, 2018
Viscous sputum specimens usually cannot undergo automated extraction, and thus, a pre-homogenization process is desirable before isolating nucleic acids for real-time reverse transcription PCR.

Long-term cultivation of two diploid epithelial cell lines derived from normal rat liver cells [PDF]

open access: yes, 1974
To obtain a useful rat liver cell line for in vitro carcinogenesis, two rat diploid epithelial cell lines were established from a 7-day-old male rat by the repeated colonial clone method.

Techniques for the Assessment of In Vitro and In Vivo Antifungal Combinations [PDF]

open access: yesJournal of Fungi, 2021
Systemic fungal infections are associated with high mortality rates despite adequate treatment. Moreover, acquired resistance to antifungals is increasing, which further complicates the therapeutic management. One strategy to overcome antifungal resistance is to use antifungal combinations.
