Many adhesion receptors have high three-dimensional dissociation constants (Kd) for counter-receptors compared to the KdS of receptors for soluble extracellular ligands such as cytokines and hormones. Interaction of the T lymphocyte adhesion receptor CD2 with its counter-receptor, LFA-3, has a high solution-phase Kd (16 microM at 37 degrees C), yet the(More)
We have used an in vitro model system of glass-supported planar membranes to study the effects of lateral mobility of membrane-bound receptors on cell adhesion. Egg phosphatidylcholine (PC) bilayers were reconstituted with two anchorage isoforms of the adhesion molecule lymphocyte function-associated antigen 3 (LFA-3). The diffusion coefficient of glycosyl(More)
In PKI (Public Key Infrastructure), certificate revocation list (CRL) carries important information of the revoked certificates. Users need to check with this CRL frequently to make sure that the certificate in consideration is still valid and has not been revoked. In a wired network, this CRL is stored in a centralized Certificate Authority (CA) and can be(More)
Intercellular adhesion molecule-1 (CD54), a cell adhesion molecule and the receptor for the major group of rhinoviruses, is a class 1 membrane protein with five Ig-like domains in its extracellular region, a transmembrane domain, and a short cytoplasmic domain. The amino-terminal domains (D1 and D2) are sufficient for virus binding and the first is most(More)
This paper presents an analytical and experimental methodology to determine the physical strength of cell adhesion to a planar membrane containing one set of adhesion molecules. In particular, the T lymphocyte adhesion due to the interaction of the lymphocyte function associated molecule 1 on the surface of the cell, with its counter-receptor, intercellular(More)
BACKGROUND Electroconvulsive therapy (ECT) remains one of the most effective tools in the psychiatric treatment armamentarium, particularly for refractory depression. Yet, there remains a subset of patients who do not respond to ECT or for whom clinically adequate seizures cannot be elicited, for whom ketamine has emerged as a putative augmentation agent.(More)
Recent work on whole genome alignment has resulted in efficient tools to locate (possibly) conserved regions of two genomic sequences. Most of such tools start with locating a set of short and highly similar substrings (called anchors) that are present in both genomes. These anchors provide clues for the conserved regions, and the effectiveness of the tools(More)
In the sequencing process, reads of the sequence are generated, then assembled to form contigs. New technologies can produce reads faster with lower cost and higher coverage. However, these reads are shorter. With errors, short reads make the assembly step more difficult. Chaisson et al. (2004) proposed an algorithm to correct the reads prior to the(More)
YE1/48 is a murine cell surface disulphide-linked dimeric Ag consisting of two 45,000-50,000 Mr subunits. It is expressed on some T lymphoma lines at high levels but its expression on normal lymphocytes is very low. The functional significance of this Ag is currently unknown. We have now cloned a cDNA encoding the YE1/48. Sequence analysis revealed that it(More)
