Characterizing the mechanical properties of tissues is key for understanding fundamental biological processes such as morphogenesis or tumor progression. In particular, intercellular adhesion forces, mediated by transmembrane proteins like cadherins, are expected to control topology and viscoelastic behavior under stress. order understand influence in tissues, we use biomimetic emulsions which ...

In this study, six types of Kashar cheese, five with added herbs and one without any additives, which is determined as a control sample were produced. Urtica dioica L. (nettle), Petroselinum crispum (parsley), Mentha piperita (mint) Eruca vesicaria (arugula), Chaerophyllum byzantinum Boiss. (mendek) to cheese clot in proportion 0.1% amounting 0.1-0.3 cm split particles depending on the milk use...

Polymorphonuclear leukocytes (PMN) degranulate, adhere to vascular endothelium, or aggregate to each other following exposure of the cells to high concentrations of chemotactic stimuli such as formyl-methionyl-leucyl phenylalanine (FMLP). PMN released the specific granule product lactoferrin more readily in response to chemotactic stimuli, which correlated with promotion of PMN aggregation as m...

We evaluated neutrophil adhesive function in patients undergoing chronic hemodialysis using either prostacyclin or heparin as antithrombotic agents. Patients underwent successive hemodialyses with prostacyclin (4 ng/kg/min) and heparin. There were no significant differences noted in neutrophil adhesive function during either dialysis: transient neutropenia developed in each case; impaired neutr...

Earlier work indicated a fall in the level of linoleate, determined by gas chromatography, in the serum of patients in the active phases of multiple sclerosis (Baker, Thompson, and Zilkha, 1964; 1966). In a series of 35 patients with multiple sclerosis the level in the serum of the cholesteryl linoleate fraction, separated by thin-layer chromatography, was reduced in patients with clinical evid...

Cationic protein purified from rabbit peritoneal polymorphonuclear leukocytes (PMN) was demonstrated to incite autoaggregation of the rabbit PMN and promote adhesiveness of human PMN to endothelial cells. PMN aggregation induced by supernatants derived from secretory PMN was blocked by a specific anticationic protein antibody. These studies reveal that a positively charged protein derived from ...

Determination of the percentage of cells in clumps on a stained smear of human peripheral blood porvided a useful, accurate technique for measuring cell adhesiveness. Smears of human peripheral blood drawn with EDTA were prepared on a blood slide centrifuge, stained, and examined under a light microscope. Statistical analysis showed that the method resulted in a Poisson distribution of particle...
