摘要:
The invention provides methods for determining the activity of a plurality of nucleic acid regulatory elements. These methods may facilitate, e.g., the systematic reverse engineering, and optimization of mammalian cis-regulatory elements at high resolution and at a large scale. The method may include integration of multiplexed DNA synthesis and sequencing technologies to generate and quantify the transcriptional regulatory activity of e.g., thousands of arbitrary DNA sequences in parallel in cell-based as says (e.g., mammalian cell based assays).

Methods for alleviating the suppression of humoral immunity by myeloid-dependent suppressor cells (MDSCs) are provided which include the administration of a VISTA antagonist and an iNOS/NO inhibitor in a subject in need thereof, e.g., subjects with cancer or infectious disease wherein VISTA is aberrantly expressed. This combination has been discovered to elicit a synergistic or additive effect on alleviating suppression of humoral immunity by VISTA which is elicited by MDSCs.

Disclosed are Dpo4 DNA polymerase mutants with increased DNA synthesis processivity. The mutant enzymes, Dpo4 A181D and Dpo4 E63K, are constructed based on the wild-type Dpo4 derived from Sulfolobus solfataricus to obtain Dpo4DNA polymerase mutants with increased DNA processivity. The extension length of Dpo4 A181D and Dpo4 E63K are respectively increased by 25% and 18.8% than that of the wild-type Dpo4. The fidelity of Dpo4 A181D and wild-type Dpo4 are similar, and the fidelity of Dpo4 E63K is increased from that of the wild-type Dpo4. In summary, the mutants Dpo4 A181D and Dpo4 E63K obtained by the present invention have increased processivity compared to that of the wild-type Dpo4 DNA polymerase.

Aspects of this disclosure describe measuring intervals within a cardiac cycle to, for example, determine whether a patient is a candidate for cardiac therapy initiation or modification. The intervals may be measured in response to a trigger identifying a physiological event. The intervals and an identification of the physiological event may be stored. A physician or clinician may determine whether the patient is a candidate for cardiac therapy modification based on the measured intervals.
摘要:
The present invention relates to novel regulatory T cell proteins. One protein, designated PD-L3, resembles members of the PD-L1 family, and co-stimulates αCD3 proliferation of T cells in vitro. A second, TNF-like, protein has also been identified as being upregulated upon αCD3/αGITR stimulation. This protein has been designated Treg-sTNF. Proteins, antibodies, activated T cells and methods for using the same are disclosed.In particular methods of using these proteins and compounds, preferably antibodies, which bind or modulate (agonize or antagonize) the activity of these proteins, as immune modulators and for the treatment of cancer, autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis is disclosed.

The present invention provides a high exchange capacity perfluorinated resin comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures, which is prepared by copolymerizing tetrafluoroethylene, vinyl ether monomers comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures, and vinyl ether monomer comprising bromine-containing pendant group, wherein based on all monomer units in the copolymer, the mol % of tetrafluoroethylene monomer is 50-85%, the mol % of vinyl ether monomers comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures is 5-49% and the mol % of vinyl ether monomer comprising bromine-containing pendant group is 1-10%. Perfluorinated ion exchanges membrane prepared from such perfluorinated resin have resistance to various chemical media, high ion exchange capacity, high conductivity, high mechanical strength, high size stability, low membrane electrical resistance and long service life, and may be applied in fuel cells or high-temperature fuel cells.
摘要:
A gardening box is disclosed. The gardening box may include a main body having a receiving space; a separation board having a plurality of through holes to secure water absorbing units and dividing said receiving space into an upper space and a bottom space; a plurality of observing holes located at a lower portion outside the main body; and a plurality of water absorbing unit secured at the separation board, and a lower portion of the water absorbing unit exposes at the bottom space to absorb water from the bottom space to moisturize soil and plants thereabove. Water level can be observed from the observing holes because the water level of the bottom space is identical to the observing holes according to the law of communicating vases.
