The present invention provides high-complexity defined gut microbial communities capable of achieving substantial engraftment and having stability following human fecal community microbial challenge and methods of producing the same. Also provided are methods of using high-complexity defined gut microbial communities for the treatment of dysbiosis or a pathological condition in an animal.

Provided are fused ring compounds of Formula (I), Formula (II), or Formula (III), as further detailed herein, which are used for the inhibition of Ras proteins, as well as compositions comprising these compounds and methods treatment by their administration.

Compositions and methods for treating or preventing the progression of neurodegenerative diseases are provided herein. Exemplary compositions include bacterial compositions having an effective amount of viable, non-pathogenic microbes, viable, non-pathogenic bacteria, wherein at least one of the bacteria is a predatory bacteria such as Bdellovibrio bacteriovorus. The disclosed bacterial compositions can be used to treat or prevent the progression of neurodegenerative diseases such as ALS, Alzheimer's disease, Huntington's disease, and Parkinson's disease.

A composition of fecal material is prepared and administered to a subject suffering from alcohol craving, alcohol consumption and/or alcohol use disorder. The donor fecal material is enriched in beneficial microbiota associated with reduced alcohol craving and/or consumption and supplies beneficial microbiota in which the recipient is deficient, and reduces harmful microbes. Methods of preparing and administering are disclosed, along with the identification of beneficial and harmful microbiota families. The treatment is also useful for delivery of microbiota that are short chain fatty acid producers to reduce alcohol craving and/or consumption in subjects deficient in short chain fatty acids.

The present application relates to a method for inducing neurogenesis in an aganglionic or hypoganglionic segment of the distal colon of a human subject suffering from an enteric neuropathy such as Hirschsprung disease (HSCR) or intestinal hypoganglionosis through the administration of an effective dose of recombinant Glial cell line-Derived Neurotrophic Factor (GDNF) polypeptide into the distal colon of the subject. The method also permits to correct the imbalance of nitrergic and cholinergic neuron subtypes located upstream of the aganglionic or hypoganglionic segment and restore distal colon function (e.g., motility and epithelial barrier) in the subject.

A pharmaceutical composition includes a combination of a guanylate cyclase C (GUCY2C) agonist and a short-chain C2 to C5 fatty acid and/or a salt and/or a prodrug thereof in a therapeutically effective amount and one or more pharmaceutically acceptable excipients as well as to a method of preventing and/or treating colorectal tumorigenesis and/or carcinogenesis and/or chronic intestinal inflammation and/or cystic fibrosis related gastrointestinal manifestations by administering to a patient, who has developed or is at risk to develop colorectal tumorigenesis and/or carcinogenesis and/or chronic intestinal inflammation and/or cystic fibrosis related gastrointestinal manifestations, a therapeutically effective amount of a combination of a GUCY2C agonist and a short-chain C2 to C5 fatty acid or a salt or a prodrug thereof.

A method for providing a steady state plasma concentration of about 20-400 ng/ml of isoflavonoid compounds comprising the steps of a first rectal administration of the compound in a lipophilic suppository base followed by further rectal administrations no earlier than 4, 8 or 16 hours after the previous rectal administration.

A non-crystallizing blend includes cannabidiol (CBD) and cannabidiolic acid (CBDA). A method of forming a non-crystallizing blend of CBD and CBDA includes obtaining a CBD isolate including at least 80% by weight CBD, obtaining a CBDA isolate including at least 80% by weight CBDA, and combining and mixing the CBD isolate and the CBDA. A method of treating a condition includes administering a therapeutically effective amount of a non-crystallizing blend of CBD and CBDA to a patient in need thereof.

Provided herein are compositions and methods for the treatment or prevention of pathogenic infections.

Provided herein are methods of treating (e.g., inhibiting, modulating, reversing, or reducing the severity of at least one symptom of) a dysbiosis in a subject, the method comprising administering an effective amount of a composition described herein (e.g., a composition comprising polyglucosamine-arginine (PAAG)).
