Eliminating fouling in hydrocarbon pipelines by electrical techniques
A method for eliminating hydrocarbon fouling and reducing pumping power during hydrocarbon transportation. A dielectric layer covers the inner surface of a pipeline for transporting a water-hydrocarbon mixture. A proximity electrode is immersed in the water-hydrocarbon mixture, and an electrical voltage is applied across the dielectric layer.

Alternatively, the dielectric layer covers an outer surface of the pipeline and is covered by an external conducting layer. Applying a potential difference between the proximity electrode and the external conducting layer still forms a water buffer layer between the inner surface and the water-hydrocarbon mixture, which eliminates hydrocarbon fouling. |

Response to EGFR blockade
Recent large-scale analyses have demonstrated that the genomic landscape of human cancer is complex and variable among individuals of the same tumor type. Such underlying genetic differences may in part be responsible for the varying therapeutic responses observed in cancer patients. To examine the effect of somatic genetic changes in colorectal cancer on sensitivity to a common targeted therapy, we performed complete exome sequence and copy number analyses of 129 tumors that were KRAS wild-type and analyzed their response to anti-EGFR antibody blockade in patient-derived tumorgraft models. In addition to previously identified genes, we detected mutations in ERBB2, EGFR, FGFR1, PDGFRA, and MAP2K1 as potential mechanisms of primary resistance to this therapy. Alterations in the ectodomain of EGFR were identified in patients with acquired resistance to EGFR blockade. Amplifications and sequence changes in the tyrosine kinase receptor adaptor gene IRS2 were identified in tumors with increased sensitivity to anti-EGFR therapy. Therapeutic resistance to EGFR blockade could be overcome in tumorgraft models through combinatorial therapies targeting actionable genes. These analyses provide a systematic approach to evaluate response to targeted therapies in human cancer, highlight additional mechanisms of responsiveness to anti-EGFR therapies, and provide additional avenues for intervention in the management of colorectal cancer. |

Key-value store that harnesses live micro-organisms to store and retrieve digital information
A digital store comprising of a method to store digital data in live micro-organisms, and a method to selectively retrieve subsets of stored data, is disclosed. Digital data is represented as a plurality of key-value pairs. The proposed system stores copies of key-value pairs in a plurality of live micro-organisms. Upon presentation of a retrieval key, the proposed digital store retrieves the value associated with the retrieval key. Storage method for a key-value pair comprises of (a) mapping the key to a gene that expresses a unique fluorescent protein so that no two keys map to the same gene, (b) encoding the key-value pair as base-pair sequences, (c) synthesizing oligonucleotide chains from base-pairs for the key-value pair and the gene, (d) synthesizing recombinant DNA plasmids that have oligonucleotide chains for the key-value pair, the gene, and two primers, as foreign DNA inserts, (e) incorporation of recombinant DNA plasmids into live micro-organisms, (f) isolation of live micro-organisms that have absorbed the recombinant DNA plasmids, and (g) safe storage of population of live micro-organisms with embedded key-value pairs in a common pool. Retrieval of the value paired with a key comprises of (a) taking as input the retrieval key, and mapping the key to the specific gene for fluorescent protein, (b) taking a sample from the safe storage pool that contains live micro-organisms embedded with key-value pairs, (c) isolating the live micro-organisms that have expressed the gene by using high-speed fluorescence activated cell sorting or flow cytometry, (d) extracting DNA from the recombinant DNA plasmid in the isolated live micro-organisms, (d) selectively amplifying and sequencing only those DNA strands that contain the value for the key, and (e) decoding the base-pair sequence obtained after DNA sequencing to yield the value associated with the retrieval key.We also disclose two important variations. The first variation relates to the storage step. The recombinant DNA plasmid is constructed to include additional non-fluorescent oligonucleotides and genes so that during the data retrieval step, the live micro-organisms that have absorbed the said plasmid can be sorted by cell sorters based on parameters of individual cells such as cell size, cell complexity, cell phenotype, cell structure, cell function, and magnetic or electrical properties. The second variation relates to both storage and retrieval of key-value pairs with large values. To store such a key-value pair, the large value is split into smaller blocks so that a block can fit into a recombinant DNA plasmid, and a distinct pair of primers is used for each block. A block's primer pair is used to selectively amplify and sequence only the DNA that encodes the data in the block, thereby enabling the retrieval of a specific block of the value, as opposed to retrieving the entire value associated with a key. |

Transcription factors controlling differentiation of stem cells
Forced expression of a handful of transcription factors (TFs) can induce conversions between cell identities; however, the extent to which TFs can alter cell identity has not been systematically assessed. Here, we assembled a human TFome, a comprehensive expression library of 1,578 human TF clones with full coverage of the major TF families. By systematically screening the human TFome, we identified 77 individual TFs that induce loss of human-induced-pluripotent-stem-cell (hiPSC) identity, suggesting a pervasive ability for TFs to alter cell identity. Using large-scale computational cell type classification trained on thousands of tissue expression profiles, we identified cell types generated by these TFs with high efficiency and speed, without additional selections or mechanical perturbations. TF expression in adult human tissues only correlated with some of the cell lineage generated, suggesting more complexity than observation studies can explain. |
