Large numbers of tunnel-like structures apparently connecting neighbouring bilayers were found in phase-contrast microscopy of certain preparations of egg lecithin in water. These passages either cause a pairing of the bilayers or form threedimensional lattices. They appear to originate while the lecithin swells in water. Some theoretical aspects of passage formation in fluid bilayers is shown ...
The reasons for moistening of the mucous membranes are several. Ciliary action is dependent on a supply ofmucus, of the right viscosity and in correct amount; in this blanket of mucus are carried lysozymes, described by Fleming (1928), of considerable bacteriostatic and bactericidal importance. The alveoli of the lung must be kept moist, for otherwise respiratory exchanges cannot be carried on;...
Eighteen temporal lobectomy patients (9 left, LTL; 9 right, RTL) were administered four verbal tasks, an Affective Implicit Task, a Neutral Implicit Task, an Affective Explicit Task, and a Neutral Explicit Task. For the Affective and Neutral Implicit Tasks, participants were timed while reading aloud passages with affective or neutral content, respectively, as quickly as possible, but not so qu...
objective(s) articular cartilage tissue defects cannot be repaired by the proliferation of resident chondrocytes. autologous chondrocyte transplantation (act) is a relatively new therapeutic approach to cover full thickness articular cartilage defects by in vitro grown chondrocytes from the joint of a patient. therefore, we investigated the redifferentiation capability of human chondrocytes mai...
INTRODUCTION Rheumatoid arthritis synovial fibroblasts (RASF) are key players in synovial pathophysiology and are therefore examined extensively in various experimental approaches. We evaluated, whether passaging during culture and freezing has effects on gene expression and cell proliferation. METHODS RASF were passaged for up to 8 passages. RNA was isolated after each passage and cDNA array...
