Cancer cell metabolic plasticity in migration and metastasis
Clinical & Experimental Metastasis, 2021Metabolic reprogramming is a hallmark of cancer metastasis in which cancer cells manipulate their metabolic profile to meet the dynamic energetic requirements of the tumor microenvironment. Though cancer cell proliferation and migration through the extracellular matrix are key steps of cancer progression, they are not necessarily fueled by the same ...

Plasticizer migration in bloodmeal‐based thermoplastics
Journal of Applied Polymer Science, 2013ABSTRACTTri‐ethylene glycol (TEG) is an effective plasticizer for many protein‐based thermoplastics because of its low volatility, however, partial miscibility with the protein matrix may still lead to some phase separation. Spatial variation of TEG concentration in bloodmeal‐based thermoplastics as a result of processing was investigated using ...

Plasticizer Migration from Blood Lines in Hemodialysis
Artificial Organs, 1984Abstract: Polyvinylchloride (PVC) is the most commonly used material for tubing in extracorporeal circulation. It is usually plasticized by the addition of di‐2‐ethylhexyl‐phthalate (DEHP). The plasticizer is physically mixed into the PVC. The potential danger of DEHP migration into blood has been discussed. It has been suggested that the polyurethane

Plasticizer migration in nitrocellulose-based propellants
Journal of Energetic Materials, 1999Abstract An “environmentally-friendly” technique for determining plasticizer concentration profiles in propellant sheets has been developed. The method was developed in response to a need for a quick, accurate means to study plasticizer migration in experimental gun propellents.

Migration of PVC plasticizers into alcohols
Polymer, 1975Abstract The use of labelled plasticizers and radioactivity measurements in conjunction with weight loss, can give quantitative information on the amount of migrated plasticizer, and on the amount of the liquid medium that diffuses into the polymer during the migration process.

Phthalate Plasticizers Covalently Bound to PVC: Plasticization with Suppressed Migration
Macromolecules, 2010The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a good plasticization efficiency is achieved although flexibility is reduced compared with that of commercial PVC−phthalate ...

Migration of plasticizers from cling‐film
Food Additives and Contaminants, 1988Plasticizers are used to impart flexibility to plastics such as polyvinyl chloride (PVC). A survey started in 1984 has obtained details on which plasticizers are used in food contact applications in the UK and in what materials, the uses of these materials and the levels of plasticizer both in the materials and in the foods with which they have been in

Scientific Aspects of Plasticizer Migration from Plasticized Pvc Into Liquids
Polymer-Plastics Technology and Engineering, 1983Abstract The polyvinyl chloride (PVC) industry plays an important role in the total plastics industry of today. In most plastics producing countries, PVC is the leading plastic material; in others, for instance the United States and Japan, it is second only to polyethylene.

Lacquer Marring by Plasticizer Migration from Vinyl Chloride Plastics
1965Nonrigid vinyl chloride plastics may on prolonged contact mar lacquer finishes through plasticizer migration. One example where this reaction may interfere with serviceability is in the use of these plastics as coatings on electrical cords and wires.
