Abstract:
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.
Abstract:
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.

Embodiments of the present disclosure are directed to a heat exchange device that includes a condenser configured to receive a refrigerant, an evaporator having an evaporation tube bundle, a throttling device configured to receive a first portion of the refrigerant from the condenser and to expand the first portion of the refrigerant before directing the first portion to the evaporator, and an ejector having a high pressure conduit, a low pressure conduit, and an outlet conduit, the ejector is configured to receive the first portion from the throttling device or a second portion of the refrigerant from the condenser via the high pressure conduit, receive a third portion of the refrigerant from the evaporator via the low pressure conduit, mix the first portion or the second portion with the third portion to form a mixed refrigerant, and direct the mixed refrigerant to the evaporator via the outlet conduit.
Abstract:
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.
Abstract:
A cathode active material of a lithium ion battery includes a number of LiNi0.5Mn1.5O4 particles and an AlF3 layer coated on a surface of the LiNi0.5Mn1.5O4 particles. A method for making the cathode active material is provided. In the method, a number of LiNi0.5Mn1.5O4 particles are provided. The LiNi0.5Mn1.5O4 particles are added to a trivalent aluminum source solution to form a solid-liquid mixture. A fluorine source solution is put into the solid-liquid mixture to react and form an AlF3 layer coated on the surface of the LiNi0.5Mn1.5O4 particles. The coated LiNi0.5Mn1.5O4 particles are heat treated to form the cathode active material. A lithium ion battery including the cathode active material is also provided.

Abstract:
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.
