Logic-controlled flow compensation circuit for operating single-rod hydrostatic actuators
A single-rod hydrostatic actuator or pump-controlled actuator, comprises a hydrostatic pump connected in a closed circuit to a single-rod hydraulic cylinder where the cylinder velocity is directly controlled by the pump flow, without the need of intermediary valves. Due to the absence of throttling losses, the efficiency of hydrostatic actuators is considerably superior to the efficiency of conventional valve-controlled circuits. However, because of the differential areas at the cap and rod sides of the cylinder, the flows coming into and out of the cylinder do not match. Several attempts have been made to this date to produce a stable, robust and reliable circuit that can be used in everyday applications but no circuit has ever been conceived to reach the high standards of reliability and robustness required by industry. The current invention solves the problem of the differential flows with a design that is reliable, oscillation-free and robust. The present conception is based on the correction of a misstated theory concerning the modus operandi of hydrostatic actuators. The resulting design can be translated into different embodiments using electronic or hydraulic technologies and uses only logical combinations of the pressure readings at the cap and rod-sides of the circuit. |

The present disclosure describes improved adeno-associated virus (AAV) vectors for gene therapy applications in the treatment of glycogen storage disease, particularly glycogen storage disease type Ia (GSD-Ia). Described are recombinant nucleic acid molecules, vectors and recombinant AAV that include a G6PC promoter/enhancer, a synthetic intron, a G6PC coding sequence (such as a wild-type or codon-optimized G6PC coding sequence), and stuffer nucleic acid sequence situated between the G6PC promoter/enhancer and the intron, as well as between the intron and the G6PC coding sequence. The recombinant AAVs disclosed herein exhibit highly efficient liver transduction and are capable of correcting metabolic abnormalities in an animal model of GSD-Ia. |

Genes encoding insecticidal proteins
The present invention relates to novel gene sequences encoding insecticidal proteins produced by Bacillus thuringiensis strains. Particularly, new chimeric genes encoding a CryIC, CryIB or CryID protein are provided which are useful to protect plants from insect damage. Also included herein are plant cells or plants comprising such genes and methods of making or using them, as well as plant cells or plants comprising one of such chimeric gene and at least one other such chimeric genes. |

Immunotherapy methods using anti-PD-L1 antibodies in combination with EGFR1 targeted-TGF-beta immunomodulatory fusion proteins
The present invention provides for a composition and a method for treating a subject afflicted with a cancer, wherein the composition comprises therapeutically effective amounts of: (a) an anti-Programmed Death-Ligand 1 (PD-L1) antibody and (b) a targeted/immunomodulatory fusion protein comprising at least one tumor targeting moiety and at least one immunomodulatory moiety that counteracts the immune tolerance of cancer cells. |
