Bio-inspired aggregation is one of the most fundamental behaviours that has been studied in swarm robotic for more than two decades. Biology revealed that the environmental characteristics are very important factors in aggregation of social insects and other animals. In this paper, we study the effects of different environmental factors such as size and texture of aggregation cues using real ro...

A cone and plate viscometer and Coulter Counter were used to study platelet modulation of polymorphonuclear leukocyte (PMNL) aggregation caused by controlled shear stress. As an index of aggregation, the large-particle percentage (LPP) was calculated. This represents the ratio of aggregated cell count to total cell count. PMNL suspensions in buffer (1.0 X 10(7) cells per milliliter, final conce...

Light-chain amyloidosis (AL) is a degenerative disease characterized by the extracellular aggregation of a destabilized amyloidogenic Ig light chain (LC) secreted from a clonally expanded plasma cell. Current treatments for AL revolve around ablating the cancer plasma cell population using chemotherapy regimens. Unfortunately, this approach is limited to the ∼ 70% of patients who do not exhibit...

This study was conducted to evaluate the effect of 5% and 21% oxygen concentrations on chimeric embryo development. Inner cell mass (ICM) from parthenogenetic activated blastocyst were used produce ES cell-like cells. A pair zona-free tetraploid embryos one clump pESCs at passage 2 3 aggregated granulosa monolayer in such a manner that sandwiched between embryos. The aggregates prepared randoml...

Biofilm formation is crucial for bacterial community development and host colonization by Streptococcus salivarius, a pioneer colonizer and commensal bacterium of the human gastrointestinal tract. This ability to form biofilms depends on bacterial adhesion to host surfaces, and on the intercellular aggregation contributing to biofilm cohesiveness. Many S. salivarius isolates auto-aggregate, an ...

Alzheimer’s disease (AD) is a progressive neurological disorder characterized by the aggregation of two proteins, amyloid-b and hyper phosphorylated tau, and by neuronal and synaptic loss. The progress of gene-modified cells and stem cells is a particularly promising therapeutic method for AD. Gene-Modified Cell-Based Therapy for AD prior to transplantation can be beneficial for increasin...

High throughput screening of SICLOPPS libraries afforded six distinct cyclic peptides that inhibit Escherichia coli growth both in liquid and solid media. One of these peptides (LN05) reduced both bacterial growth rate and caused cell aggregation in liquid media. Mutant bacteria immune to LN05 action were obtained at a frequency of 10(-7). Over-expression of an E. coli genomic library in the pr...
