It is perhaps surprising, given the contemporary eminence of neuroscience within biological research, that it was not appreciated until the 17th century that the brain might have an important function. A compelling new book by Carl Zimmer surveys the scientific, conceptual and political upheavals in England at this time as a backdrop to the major experimental work carried out by a little-known ...
This paper has studied the pathology of human soul on the basis of Molla Sadra`s view. As is understood from him, the degree of existence in every thing requires its appropriate degree of knowledge. Such being the case, man in relation to Absolute existence is characterized with the poverty and weakness of existence and, consequently, with that of knowledge. Lack of knowledge, therefore, can b...
Epididymal spermatozoa of domestic cats were diluted with TEST medium and frozen. The parameters - estimated percentage of motile spermatozoa, concentration of spermatozoa, cell morphology and transmigration rate (TMR) - were evaluated before freezing and after thawing. Transmigration is a new method to measure the percentage of spermatozoa that consistently move forward, and has not been inves...
The endothelial receptors that control leukocyte transmigration in the postischemic liver are not identified. We investigated the role of junctional adhesion molecule-A (JAM-A), a receptor expressed in endothelial tight junctions, leukocytes, and platelets, for leukocyte transmigration during hepatic ischemia-reperfusion (I/R) in vivo. We show that JAM-A is up-regulated in hepatic venular endot...
OBJECTIVES During inflammation, cell adhesion molecules are modulated or redistributed for leukocyte transmigration. Among molecules at the interendothelial junction, CD146 is involved in cell-cell cohesion and permeability, but its role in monocyte transmigration is unknown. METHODS AND RESULTS TNF enhanced CD146 expression at the junction and apical membrane of human umbilical veins endothe...
Interaction between ICAM-1 (CD54) and fibrinogen (fg) has been shown to enhance leukocyte adhesion, but its specific role in the process of migration across endothelial cell junctions remains unclear. To overcome the problem of multiple adhesion receptors found on endothelial cells, we have engineered stable Chinese hamster ovary cell lines expressing ICAM-1 (Chinese hamster ovary ICAM-1). The ...
Neutrophil (PMN) infiltration into tissues is a hallmark of acute inflammation and is crucial for the rapid removal of microbial pathogens. Previous studies have shown that PMN transmigration is regulated by the cell surface protein CD47. However this phenomenon in the context of microbial invasion and subsequent TLR signaling is poorly understood. In this study, we assessed the role of TLR2 an...
Although several adhesion molecules expressed on leukocytes (beta1 and beta2 integrins, platelet endothelial cell adhesion molecule 1 [PECAM-1], and CD47) and on endothelium (intercellular adhesion molecule 1, PECAM-1) have been implicated in leukocyte transendothelial migration, less is known about the role of endothelial lateral junctions during this process. We have shown previously (Read, M...
Impacted canines are not uncommon in clinical practice, but intraosseous movement of impacted canines crossing the midline (transmigration) is a rare phenomenon. We report 4 cases of mandibular canine transmigration to emphasize the need to supplement periapical radiographs with a panoramic radiographic examination in patients with over-retained deciduous canines or missing permanent canines.
