Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.

Provided herein is a method of producing a protein comprising a target-specific extravesicular domain (TED) of an extracellular vesicle (EV) surface protein comprising modifying a polynucleotide comprising a nucleotide sequence encoding the extravesicular domain (ED) of an EV surface protein by a mutagenesis method within at least one modified region within the ED amino acid sequence with a length of 3-20 contiguous amino acids flanked by regions of the wild-type ED sequence at its N-terminus and C-terminus, to incorporate a target binding site within the ED, thereby producing a repertoire of polynucleotides encoding a variety of TEDs, each comprising a different target binding site, and selecting a TED specifically recognizing a predetermined target, and producing the protein comprising the selected TED.

The present invention relates to a pharmaceutical composition comprising at least one liposome and a therapeutic agent for treating an auto-immune disease with a high therapeutic agent to lipid ratio and a high encapsulation efficiency. The pharmaceutical composition improves the pharmacokinetic profile and sustains the release of the therapeutic agent. Also provided is the method for treating an auto-immune disease using the pharmaceutical composition disclosed herein.

The present disclosure provides a system for the internal and external modification of nanoparticles in a continuous process. The system includes (a) a first inlet, (b) a second inlet, (c) a first pump in fluid communication with the first inlet, (d) a second pump in fluid communication with the second inlet, (e) a first flow meter positioned between the first pump and the first mixer, (f) a second flow meter positioned between the second pump and the first mixer, and (g) a mixing chamber in fluid communication with the first flow meter and the second flow meter, and (h) a first heat exchanger in fluid communication with the mixing chamber.

The present invention relates to pharmaceutical compositions comprising at least one liposome and a therapeutic agent for treating dementia with a high drug to lipid ratio and a high encapsulation efficiency. The pharmaceutical composition improves the pharmacokinetic profile and sustains the release of the therapeutic agent. Also provided is the method for treating dementia using the pharmaceutical composition disclosed herein.

Compounds and pharmaceutical formulations containing these compounds are described. Also described are methods of making and using the compounds. The compounds include nucleobases, nucleobase analogues, or combinations thereof. In one embodiment, a nucleobase analogue is combined with doxorubicin and encapsulated within a liposome for use in inhibiting or preventing the growth of cancer cells. Further described are pharmaceutical compositions containing two or more therapeutically active agents encapsulated within a vesicle, such as a liposome, wherein the molar ratio of the agents provides a synergistic therapeutic effect.

The present disclosure discloses a preparation method of fatty acid-based VC liposomes, and belongs to the field of pharmaceutical preparations. In the disclosure, a complex of industrial conjugated linoleic acid and other fatty acids with sodium dodecyl sulfate is taken as a capsule material, which is self-assembled to embed vitamin C in an aqueous phase under an acidic condition (pH<7) to form the fatty acid-based vitamin C liposome. The preparation method of the disclosure does not use organic solvents and other substances harmful to the human body, and has the characteristics of safety and health. In addition to VC encapsulation under the acidic condition, the prepared fatty acid-based liposome can play a role in slowly releasing VC.

A liposome comprising bilayer and inner water phase is disclosed. Said inner water phase may contain sulfobutyl ether cyclodextrin and an active compound.

Engineered nano-liposomes (immuno-nanoliposomes) and their preparation process, for use as a treatment in atherosclerosis therapy, containing therapeutic mono-clonal antibodies and having poly-anions and/or poly-cations on the external surface, to which monoclonal antibodies specific for atheromatous plaques capable of guiding said nano-liposomes are grafted.

Compositions and methods for administration of local anesthetics that are delivered by a single injection and enable repeated on-demand or high influx analgesia over extended periods have been developed. Pharmaceutical compositions including an effective amount of one or more sodium channel blockers including site 1 sodium channel blockers, optionally one or more alpha-2-adrenergic agonists, which are optionally encapsulated in liposomes, particles or microbubbles, and one or more triggerable elements are provided. The triggerable elements allow delivery of the encapsulated anesthetic drugs when an appropriate triggering stimuli are applied. Exemplary triggering agents or stimuli include near-infrared irradiation, UV- and visible light, ultrasound and magnetic field. In one embodiment, ultrasound is used to trigger a burst of microbubbles to enhance penetration of local anesthetic.
