Basic Surface Properties of Mononuclear Cells from Didelphis marsupialis [PDF]

Memorias do Instituto Oswaldo Cruz, 1998
The electrostatic surface charge and surface tension of mononuclear cells/monocytes obtained from young and adult marsupials (Didelphis marsupialis) were investigated by using cationized ferritin and colloidal iron hydroxyde, whole cell electrophoresis ...

Electrostatic Interaction with the Bacterial Cell Envelope Tunes the Lytic Activity of Two Novel Peptidoglycan Hydrolases

Microbiology Spectrum, 2022
Peptidoglycan (PG) hydrolases, due to their crucial role in the metabolism of the bacterial cell wall (CW), are increasingly being considered suitable targets for therapies, and a potent alternative to conventional antibiotics.

Measurement and visualization of cell membrane surface charge in fixed cultured cells related with cell morphology.

PLoS ONE, 2020
The diagnosis of patients with malignancies relies on the results of a clinical cytological examination. To enhance the diagnostic qualities of cytological examinations, it is important to have a detailed analysis of the cell's characteristics. There is,

Decay of Electric Charge on Corona Charged Polyethylene [PDF]

, 2007
In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Translocating the blood-brain barrier using electrostatics

Frontiers in Cellular Neuroscience, 2012
Mammalian cell membranes regulate homeostasis, protein activity and cell signaling. The charge at the membrane surface has been correlated with these key events.Although mammalian cells are known to be slightly anionic, quantitative information on the ...

Role of surface charge and oxidative stress in cytotoxicity of organic monolayer-coated silicon nanoparticles towards macrophage NR8383 cells [PDF]

, 2010
Background - Surface charge and oxidative stress are often hypothesized to be important factors in cytotoxicity of nanoparticles. However, the role of these factors is not well understood.

Cell surface charge characteristics and their relationship to bacterial attachment to meat surfaces [PDF]

Applied and Environmental Microbiology, 1989
Cell surface charge and hydrophobicity of Bacillus subtilis, Escherichia coli O157:H7, Listeria monocytogenes, Salmonella typhimurium, Serratia marcescens, Staphylococcus aureus, and Staphylococcus epidermidis were determined by hydrocarbon adherence, hydrophobic interaction, and electrostatic interaction chromatography.

Positively charged nanocomplex modulates dendritic cell differentiation to enhance Th1 immune response

Materials Today Bio, 2022
Most existing vaccines use activators that polarize the immune response to T-helper (Th) 2 response for antibody production. Our positively charged chitosan (Cs)-based nanocomplex (CNC) drives the Th1 response through unknown mechanisms. As receptors for

The surface charge of trypanosomatids of the genus trypanosoma

Memorias do Instituto Oswaldo Cruz, 1990
Cell electrophoresis was used for determionation of the electrophoretic mobility (EPM) of epimastigo and trypamastigote forms of several isolates of Trypanosoma cruzi and some stocks of other members of the Schizotrypanum subgenus, such as T. dionisii, T.
