long-term complications of retained war fragments in the body are not completely known. also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. we reviewed the literature on complication of retained war fragments and report our...

We describe highly effective adhesion culture of human pluripotent stem cells (hPSCs) using laminin fragments without precoating. Culture substrates have been generally thought to exert a cell adhesion effect when they are precoated onto culture vessels. However, simple addition of laminin fragments to a cell suspension during passaging accelerated the adhesion of single dissociated hPSCs onto ...

(Woody community dynamics in two fragments of “cerrado” stricto sensu over a seven-year period (1995-2002), MA, Brazil). This study was conducted in two fragments of “cerrado” stricto sensu in the Gerais de Balsas Colonization Project, located in southern Maranhão, Brazil. The objective was to evaluate the dynamics of the woody plant community, over seven years (1995-2002). Four transects of 16...

Pairwise local alignment is one of the most important problems in sequence analysis in computational biology. Classical dynamic programming solution to this problem searches for two segments with maximum similarity score by discarding poorly conserved initial and terminal fragments. As a consequence, an alignment returned as optimal may contain a mosaic of well-conserved fragments arti cially c...

Cyanophages (viruses that infect cyanobacteria) are abundant in the marine environment and are thought to be a significant factor in determining the population dynamics of members of the unicellular phycoerythrin-containing cyanobacteria of the genus Synechococcus. In an effort to use molecular techniques to characterise cyanophage populations, a conserved region from the cyanophage genome was ...

Background: Potyviruses are accounted for 40% of viral diseases of various crops including vegetables and legumes. Potyviruses can be transmitted through plant sap, seeds and many aphid species. Due to ease of spread of these viruses detection of such viruses are crucial as to the control of the incited diseases. Objectives: This study compared the efficiencies of two couples of primers in the...

Robust prediction of the motion of debris from explosions is critical to the estimation of separation distances, fragment density, and debris lethality in explosive safety hazard analysis. Debris dispersion models have been developed and applied to many specific types of hazardous debris (ranging from masonry, concrete, structural steel elements, soil and rock ejecta, to bomb fragments). These ...

We describe a multiple-sequence alignment algorithm for determining the highest-scoring alignment that can be obtained by chaining together non-overlapping subalignments selected from a given collection of such \fragments". For a given set of K sequences, a problem instance consists of a set of F precomputed fragments, an alignment score for each fragment, and a \gap" penalty function that assi...

Human rhinoviruses are the major causative agents of the common cold in humans and have been divided into major and minor groups based on receptor specificity. cDNAs encoding the light and heavy chains of a murine monoclonal antibody that recognizes the major group receptor were cloned, abundantly expressed in Escherichia coli, and renatured into Fab fragments that blocked virus binding and pro...

Intramammary infection with Streptococcus uberis is a common cause of bovine mastitis throughout the world. Several procedures to differentiate S. uberis isolates have been proposed. However, all are prone to interlaboratory variation, and none is suitable for the description of the population structure. We describe here the development of a multilocus sequence typing (MLST) scheme for S. uberi...
