Studies on Lymphocyte-Mediated Cytolysis
The Journal of Immunology, 1978Abstract Lymphocyte and mastocytoma (P815) cell populations incubated with DNP-phosphatidylethanolamine in the form of liposomes displayed cell surface hapten as evidenced by: i) 125I-anti-DNP antibody binding; ii) C-mediated lysis, and iii) K-cell mediated lysis. Under optimal conditions, P815 cells incubated with DNP-liposomes showed a

Developmental Studies of Mediated Memory
1970Publisher Summary This chapter summarizes five developmental studies of mediational and, especially, production deficiencies with respect to children's performance on memory tasks. Some generalizations about the nature and development of mediational activity and related topics have been proposed and recent studies dealing with the development of ...

Progress in Studying Mediator Supercapacitor
ECS Meeting Abstracts, 2016When mediators (redox molecules) are mixed into an ion conducting polymers, the material will have a high ionic conductivity and electronic conductivity potentially providing a high storage capacity and charge/discharge rate. On the basis of our previous work of developing I2/NaI and K3Fe(CN)6/K4Fe(CN)6based supercapacitors, we studied the ionic ...

Shape Mediation Analysis in Alzheimer's Disease Studies
Statistics in MedicineABSTRACTAs a crucial tool in neuroscience, mediation analysis has been developed and widely adopted to elucidate the role of intermediary variables derived from neuroimaging data. Typically, structural equation models (SEMs) are employed to investigate the influences of exposures on outcomes, with model coefficients being interpreted as causal effects.

Polyethylenimine-mediated gene delivery: a mechanistic study
The Journal of Gene Medicine, 2001Ethylenimine polymers (PEIs) belong to one of the most efficient family of cationic compounds for delivery of plasmid DNA into mammalian cells. The high transfection efficiencies are obtained even in the absence of endosomolytic agents such as fusogenic peptides or chloroquine, which is in contrast to most of the other cationic polymers.

Simulation Study of Protein-Mediated Vesicle Fusion
The Journal of Physical Chemistry B, 2008A dissipative particle dynamics simulation method is used to probe the mechanism of protein-mediated membrane fusion. The coarse-grained models for proteins are designed based on the function of fusion proteins. Attractive forces have been introduced to produce a protein complex.

Studies of DEAE‐dextran‐mediated gene transfer
Biotechnology and Applied Biochemistry, 1997DEAE‐dextran‐mediated gene transfer was studied for the introduction of pSV2neo DNA into Fisher‐rat 3T3 (FR3T3) cells. Zeta (z) potentials of the DEAE‐dextranŐDNA complexes and FR3T3 cells were found to be dependent on the concentration of DEAE‐dextran in the medium.

Methods to Study Chaperone-Mediated Autophagy
2017Chaperone-mediated autophagy (CMA), a selective form of degradation of cytosolic proteins in lysosomes, contributes to maintenance of proteostasis and to the cellular adaptation to stress. CMA substrates are selectively recognized and delivered by a cytosolic chaperone to the lysosomal surface, where, upon unfolding, they are internalized through a ...

Studies of influenza haemagglutinin-mediated membrane fusion
Virology, 1986A resonance energy transfer assay of membrane fusion developed by P. S. Uster and D. W. Deamer (Biochemistry 24, 1-8 (1985)) was used in a study of influenza haemagglutinin-mediated fusion. The characteristics of fusion and haemolysis by X-31 (H3N2) virus, a number of mutants of X-31 which fuse membranes at higher pH, and purified haemagglutinins ...

Acid-Mediated Tumor Invasion: a Multidisciplinary Study
Cancer Research, 2006AbstractThe acid-mediated tumor invasion hypothesis proposes altered glucose metabolism and increased glucose uptake, observed in the vast majority of clinical cancers by fluorodeoxyglucose-positron emission tomography, are critical for development of the invasive phenotype.
