Abstract: A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure; a frame member attachable to the retaining structure; and a positioning and stabilising structure attachable to the frame member.

Abstract: The present disclosure provides methods and compositions for microglia replacement therapy in a subject in need thereof. In some cases, the method involves administering myeloid cells to the central nervous system of a subject. In some cases, the myeloid cells are derived from embryonic or extraembryonic tissue. In some cases, the myeloid cells are genetically modified. The genetic modification may include a colony stimulating factor 1 receptor (CSF1R) variant that is resistant to a CSF1R inhibitor, yet retains sensitivity to its ligand (e.g., CSF1, IL34).

Abstract: Fusion proteins having thermostable blunt-end ligase activity are provided. Blunt-end ligases are useful for DNA amplification, sequencing, production of recombinant DNA and recombinant fusion proteins, and other purposes. These thermostable blunt-end DNA ligases are useful in ligation schemes which include, e.g., an incubation at about 60-65° C. or higher, or as high as about 94° C., or at other temperatures. The ligases disclosed herein may enable high temperature blunt-end ligation without need for molecular crowding agents, and so may be useful for many nucleic acid ligation-amplification schemes, e.g., ones which operate at a uniform temperature (e.g., at about 60° C. or higher), including ones which require temperature cycling, e.g., from about 94° C. to about 60° C. (or higher) for one, two, three, or more cycles.

Abstract: Thermostable blunt-end ligases suitable for use in nucleic acid ligation reactions at elevated temperatures are provided. The ligases comprise fusion proteins including a DNA ligase and a DNA binding protein, e.g., a T4 DNA ligase with an N-terminal p50 fusion. The fusion proteins may include peptide linkers, peptide mimetics, terminal additions, tag peptides, D-amino acids, sugars, non-amino acid organic moieties, and polymers. The ligases are suitable for use in ligation reactions, including uniform-temperature ligation reactions, performed at about 60° C. or higher, e.g., at about 75° C. The ligases are suitable for use in nucleic acid amplification schemes with temperature cycling, e.g., temperature cycles to about 60° C. or higher, or temperature cycles from about 94° C. to about 60° C. Such nucleic acid amplification schemes may include one, two, three, or more temperature cycles. Methods of using the ligases, and articles of manufacture comprising the ligases are provided.

Abstract: Methods of preparing normalized mixtures from a plurality of nucleic acid samples are disclosed. Nucleic acids are amplified so that similar amounts of a target nucleic acid are generated in a plurality of different reactions. Separate amplification reactions are performed to amplify the same or different targets in a plurality of different reactions. The amounts of amplified product are approximately normalized during the amplification without the need to empirically measure the amount of amplified target.

Abstract: The present invention provides methods for marking nucleic acid samples with detectable markers by adding different combinations of marker molecules to each sample. Each sample may be marked with a different combination of two or more marker molecules each carrying a different tag nucleic acid sequences. The tag nucleic acid sequences may be random sequences that are not naturally occurring in the nucleic acid sample and do not cross hybridize to sequences naturally occurring in the nucleic acid sample. Methods of detecting the combination of tag sequences present in a sample, in parallel with methods of genetic analysis of the sample are disclosed. Kits containing marker molecules suitable for generating barcoded samples by mixing different combinations of marker molecules into each sample are also disclosed.
