Abstract: T-cell responses are initiated via contact with MHC/peptide complexes on antigen presenting cells (APCs). The fate of these complexes, however, is unknown. Here, using live APCs expressing MHC class I molecules fused with green-fluorescent protein, we show that peptide-specific T-cell/APC interaction induces clusters of MHC I molecules to congregate within minutes at the contact site; thereafter, these MHC I clusters are acquired by T-cells in small aggregates. We further demonstrate that acquisition of MHC I by T-cells correlates with TCR down regulation and the APC-derived MHC I molecules are endocytosed and degrated by T-cells. These data suggest a novel mechanism by which TCR recognition of MHC/peptide complexes can be curtailed by internalization of MHC molecules by T-cells.

Abstract: A technique is presented for compressing data which leverages the frequency of an escape symbol for better compression. The prefix of a data string is evaluated and the probability of all characters that might succeed it is predicted in tabular form. Symbols are designated "Hit" or "Miss" based upon whether they are in the table. A binary tree is generated by partitioning nodes into Zero and One groups based on a single bit value. A partition bit is chosen to maximize the difference of probability sums of Hit symbols in Zero and One groups, with exceptions for partitions having non Hit symbols in one of the groups. A probability value is assigned to each branch, based on the probabilities of Hit and Miss symbols. Encoding a symbol is facilitated by encoding the branch probabilities on the shortest path from the root to the leaf node containing the symbol using arithmetic encoding.

Abstract: Appareil de filtrage de débris en fond de trou. Dans un mode de réalisation préféré, le dispositif de déviation d'écoulement est rétracté lorsque l'outil est mis en route pour faciliter le passage de débris. La vitesse de dépôt est la vitesse à laquelle les débris chutent dans le fluide. La vitesse de dépôt dépend de la densité du fluide et de la densité des débris. Si la vitesse de fluide dépasse la vitesse de dépôt, les débris remontent. La région annulaire restreinte autour des tamis augmente la vitesse de fluide. Au-dessus de la gaine en coupelle, la région annulaire augmente significativement et la vitesse de fluide est réduite sous la vitesse de dépôt pour permettre aux débris de se déposer au fond de l'outil. Lors de la mise en route, le fluide contourne simplement filtre. Les gros débris se déposent dans l'outil comme décrit. Lorsqu'il est retiré du trou, le dispositif de déviation d'écoulement/coupelle de frottement est actionné en contact avec le tubage ou la paroi de colonne et un grand passage est ouvert pour permettre l'écoulement à travers le filtre. Les petits débris qui sont montés au-dessus de l'outil sont capturés lorsque le fluide est filtré à travers le tamis. Un autre mode de réalisation avec une coupelle non rétractable utilise une soupape de gaine coulissant avec une grande surface ouverte qui favorise un écoulement libre et minimise l'encrassement dû aux débris déposés.

Abstract: cDNAs (RISBZ1, RISBZ4, and RISBZ5) encoding bZIP transcription factors were isolated from a cDNA library originating in rice plant seed. The cDNAs encode novel proteins and have binding activity to the GCN4 motif. Among them, RISBZ1 activated transcription mediated by the GCN4 motif by 100-fold or more. Since the expression of RISBZ1 precedes the expression of a seed storage protein gene and is expressed only in maturing seeds, it is suggested that RISBZ1 controls the expression of rice seed storage proteins. In addition, by linking the recognition sequence of the transcription factor, the GCN4 motif, in tandem and introducing it into the promoter for a gene encoding seed storage protein to facilitate its binding to the transcription factor RISBZ1, expression of a foreign gene under the control of the modified promoters is greatly enhanced.

Title: Universal tension spring support member for bed rails or bed frame

IPC: A47C19/02
Filed: 2001-03-05
Granted: 2010-06-08
Abstract: A universal cross member (18) that can be used with a bed frame or bed rails to provide support for a box spring and mattress. The universal cross member (18) has a straight bar (20) with telescoping ends so that the universal cross member (18) be used even where there are variances in the distance between the side rails (10) and still be fitted to those side rails. A tensioning system is provided to add strength to the universal cross member (18) to eliminate, in almost all instances, the need for some further support of the universal cross member (18) from the floor, such as a caster or a glide. In the system, a tensioning bar (26) has its ends affixed at or near the ends of the straight member (20) and its center contacts a block at a finite distance from the straight member (20) at or about the center of the straight member. By placing the tension bar (26) in a predetermined tension, a force is created that acts through the block (30) against the approximate center of the straight member (20). That tension can be created by pulling the ends of the tensioning bar (26) outwardly near its end. The tension bar (26) thus creates a force against the straight member (20) at its center but also pulls the ends of the straight member (20) inwardly to stress the straight member (20) toward a bowed configuration where the center is bowed away from the direction of the force and the ends bowed in the opposite directions. Thus, the stress counters the weight imposed on the universal cross member by the box spring, mattress and other components supported by the universal cross member (18) and the need for additional support from the floor is eliminated and the universal cross member can be used independent of the height of the side rails from the floor.
