  • Patent number: 12254220
    Abstract: One or more parameters corresponding to a targeted energy characteristic of a computing client device are received. A ratio of types of storage devices allocated to the computing client device is adjusted based on the one or more parameters. A storage volume for the computing client device is provisioned according to the ratio of the types of the storage devices.

  • Publication number: 20250082714
    Abstract: The disclosure provides methods for treating muscular dystrophy (MD), such as Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) in a mammalian subject. The methods comprise administering to the subject an effective amount of a peptide such as H-D-Arg-2,6-Dmt-Lys-PHe-NH2 (SEQ ID NO: 2) (a.k.a. MTP-131 or elamipretide), or a pharmaceutically acceptable salt, hydrate, solvate and/or tautomer thereof, in combination with at least one phosphorodiamidate morpholino oligomer (PMO) or peptide-conjugated PMO (PPMO). The methods are particularly useful for increasing dystrophin expression levels in subjects diagnosed with, and/or being treated for, MD in an amount greater than what would be possible by treatment with the PMO or PPMO alone.

  • Publication number: 20250009717
    Abstract: The present disclosure provides novel methods for treating or preventing amyotrophic lateral sclerosis (ALS), methods for delaying the onset of neurological symptoms associated with ALS, increasing survival in subjects afflicted with ALS, and attenuating the decline of muscle strength associated with ALS in a subject in need thereof. The present disclosure also provides methods for treating or preventing ?-synucleinopathy or TDP-43 proteinopathy. The methods comprise administering to the subject an effective amount of a mitochondria-targeting peptidomimetic compound, such as (R)-2-amino-N-((S)-1-(((S)-5-amino-1-(3-benzyl-1,2,4-oxadiazol-5-yl)pentyl)amino)-3-(4-hydroxy-2,6-dimethylphenyl)-1-oxopropan-2-yl)-5-guanidinopentanamide, or a pharmaceutically acceptable salt, stereoisomer, tautomer, hydrate, and/or solvate thereof.

  • Patent number: 11481491
    Abstract: Virus scanning of container images can be managed. For example, container images can be received in a sequential order. The container images can then be analyzed to determine the contents of the container images. The container images can be arranged in a virus-scanning queue in an order that is different from the sequential order in which the container images were received based on the contents of the container images. The container images can then be scanned for viruses in the order in which the container images are arranged in the virus-scanning queue.

  • Publication number: 20220206998
    Abstract: Container images can be copied. For example, a computing device can segment a container image into at least two data chunks. The computing device can determine a reference count for a data chunk among the at least two data chunks. The computing device can determine that the reference count for the data chunk is below a threshold value. In response to determining that the reference count for the data chunk is below the threshold value, the computing device can prevent a destination device from being queried about the data chunk prior to transmitting the data chunk to the destination device.
