The surface layer of Candida albicans.

The surface of Candida albicans is covered by a mucus layer secreted by the cell. Excess mucus secretion accumulates between the cells, and contains protein, polysaccharides and secreted enzymes. In mature cultures dead cells are trapped in the mucus, and the accumulated mucus and cell debris facilitate the formation of plaque, and the penetration of C. albicans into infected host tissues.     

Laboratory studies on fluctuating phenomena

Alternating electromagnetic and electrical fields, applied to colloidal systems or to their suspending media, result in increases in sedimentation rate, electrophoretic mobility, resistivity, viscosity, and shock-freezing temperature, while magnetic fields and static electrical fields result in decreasing sedimentation rates.

Zusammenfassung Wechselnde elektromagnetische und elektrische Felder,die auf kolloidale Systeme oder deren Suspensionsmedium einwirken, führen zu einem Anstieg der Sedimentationsrate, elektrophoretischen Beweglichkeit, spezifischen Widerstandskraft, Viskosität und Schock-Gefriertemperatur, während magnetische Felder und statische elektrische Felder zu einer Verlangsamung der Sedimentationsrate führen.

Resume Des champs électromagnétiques et électriques alternatifs agissant sur des systèmes colloïdaux ou le milieu dans lequel ils sont en suspension y provoquent un accroissement de la vitesse de sédimentation, de la mobilité électrophorétique, de la résistivité, de la viscosité et de la température de congélation par chocs. Des champs magnétiques constants ou de l'électricité statique conduisent, au contraire, à un ralentissement de leur vistesse de sédimentation.

Characterization of the alkyl ether species of phosphatidylcholine in bovine heart

The molecular types of lecithin in beef heart lipids were investigated by a combination of mild hydrolytic procedures and silicic acid chromatography. The major species of sn-glycero-3-phosphorylcholine (GPC) were found to be: diacyl-GPC (57%), alk-l-enyl, acyl-GPC (39%), alkyl acyl-GPC (3%), and dialkyl-GPC ( less than 1%). No di-alk-l-enyl-GPC or alk-l-enyl alkyl-GPC were detected. The derived monoalkyl-and dialkyl-glycerols were characterized by their infrared spectra and alkyl chain compositions.
