  • Patent number: 12201725
    Abstract: The present disclosure provides a dry powder composition of treprostinil prodrugs and a method of treating pulmonary hypertension (e.g., pulmonary arterial hypertension), portopulmonary hypertension, or pulmonary fibrosis in a patient in need thereof. The dry powder composition includes (a) from about 0.1 wt % to about 3 wt % of a compound of Formula (I): or an enantiomer, diastereomer, or a pharmaceutically acceptable salt thereof, (b) from about 0.01 wt % to about 3 wt % of DSPE-PEG2000, (c) from about 10 wt % to about 50 wt % of leucine, and the balance being (d) a sugar selected from the group consisting of trehalose and mannitol. The entirety of (a), (b), (c), and (d) is 100 wt %, and R1 is tetradecyl, pentadecyl, hexadecyl, heptadecyl, or octadecyl. The method includes administering an effective amount of the dry powder composition to the lungs of the patient by inhalation via a dry powder inhaler. In certain compositions and methods provided herein, R1 is hexadecyl, e.g., linear hexadecyl.

  • Patent number: 12163429
    Abstract: The present disclosure relates to the technical field of tunnel construction, in particular to a design method of a buffer layer with critical deformation of a tunnel initial support as a control target. The method includes the following steps: (1) establishing a mechanical model and calculating an ultimate bearing capacity of the tunnel initial support during critical damage based on a cusp catastrophe theory; (2) determining a critical deformation value of the tunnel initial support under the ultimate bearing capacity; (3) establishing a yielding control target of a tunnel buffer layer; (4) determining a performance index of the buffer layer according to the control target, and calculating corresponding index parameters. Compared with the prior art, the method has the following beneficial effects.

  • Publication number: 20240285570
    Abstract: The present disclosure provides dry powder compositions of treprostinil prodrugs and methods of treating pulmonary hypertension (e.g., pulmonary arterial hypertension or PH associated with interstitial lung disease), in a patient in need thereof with the same. The dry powder composition includes (a) from about 0.5 wt % to about 5 wt % of a compound of Formula (I): a stereoisomer thereof, or a pharmaceutically acceptable salt thereof, (b) from about 10 wt % to about 61 wt % of leucine, and the balance being (c) a sugar selected from the group consisting of trehalose and mannitol. The entirety of (a), (b), and (c) is 100 wt %, and R1 is tetradecyl, pentadecyl, hexadecyl, heptadecyl, or octadecyl. The method of treating PH includes administering an effective amount of the dry powder composition to the lungs of the patient by inhalation via a dry powder inhaler, during an administration period. In certain compositions and methods provided herein, R1 is hexadecyl, e.g., linear hexadecyl.

  • Publication number: 20240176435
    Abstract: A method is provided. The method comprises: obtaining, by a processing system and using a set of rotation electrodes that interact with the knob interface, first resulting signals and second resulting signals; determining, by the processing system, an initial state of the knob interface using the first resulting signals and the second resulting signals; obtaining, by the processing system and using the set of rotation electrodes, third resulting signals indicating a first rotational state of the knob interface, based at least in part on the knob interface being rotated from the initial state to the first rotational state; determining, by the processing system, the rotational direction of the knob interface using the first resulting signals, the second resulting signals, and the third resulting signals; and adjusting, by the processing system, a setting using the determined rotational direction.
