A porous silica particles according to an embodiment of the present disclosure includes a plurality of pores with a diameter of 5 nm to 100 nm. The porous silica particles have particular physical properties, can deliver all various drugs by a supported amount in a sustained manner, and can be parenterally administered.

A method of treating cancer in a subject, including: providing a subject having a plurality of cancer cells; and administering to the subject, a therapeutically effective amount of a composition including: an HDM-2 binding component; and a membrane resident component, the membrane resident component bound to the HDM-2 binding component. Also provided are a method of selectively necrosing cancer cells, a method of causing membranolysis in cancer cells, and a cancer treatment composition.

Compositions, systems and methods of improving the health of the microbiome of an individual's skin relate to the provision of skin contacting formulations containing beneficial bacteria and other microbe components to foster the growth and maintenance of a healthy skin microbiome. A topical application of Lactobacillus crispatus is employed to ameliorate skin barrier damage and inflammation using unique combinations of probiotics, prebiotics, and other skin-beneficial ingredients, effectively treating inflammatory skin diseases, such as atopic dermatitis, psoriasis and acne. The topical application of Lactobacillus crispatus to an individual's skin reduces inflammation through the production of tryptophan metabolites that act as AHR agonists.

A method for reducing the likelihood of an individual developing colorectal cancer includes the use of a CRISPR system to selectively kill pathogenic bacteria, such as Klebsiella and E coli, within the individual. Preferrably, the growth of a beneficial bacteria, such as Akkermansia, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Fusobacterium, Coprococcus, Lactobacillus, Propionibacterium, Ruminococcus, Veillonella, Prevotella, and Streptococcus bacteria, is also enhanced. Reduction of certain virulence factors, such as colibactin, using a CRISPR system, as well the employment of immune checkpoint inhibitors, is effective in treating individuals with cancer and who suffer from a chronic infectious disease.

Various embodiments of the present invention are directed to the field of treating and preventing osteoporosis, with particular embodiments directed to a method of ameliorating, treating, or preventing osteoporosis in a human subject employing tomatidine, xylitol, rapamycin, etc., as well as modifying an individual's microbiome to reduce the likelihood of osteoporosis.

A method for reducing the likelihood of developing depression in an individual involves providing in the gut of an individual a population of beneficial bacteria selected from the group consisting of bacterial species able to make small chain fatty acids, and preferably butyrate, and administering fiber to the individual to maintain a therapeutically effective amount of the beneficial bacteria in the gut of the individual. The individual's gut microbiome is modified to reduce the number of undesired bacteria and to increase the number of beneficial bacteria. Bacteria are preferably modified to remove one or more virulence facts or alternatively to produce increased amounts of SCFA's, such as butyrate. Beneficial bacteria may be encapsulated in a frangible enclosure to ensure they arrive in an individual's body while still viable, e.g. such as being first released in the lower gut rather than being exposed to the harsh conditions of an individual's stomach. In other embodiments, a therapeutically effective amount of a bacterial formulation comprising Faecalibacterium prausnitzii is administered. Other embodiments include the administration of a bacterial formulation comprising at least one of Coprococcus, Roseburia, Bifidobacterium, Faecalibacterium prausnitzii and L. casei to treat depression.

The present disclosure is directed to methods and compositions for inhibiting a cancer cell using nucleic acid sequences encoding elephant p53 or elephant p53 amino acid sequences.

Compositions, systems and methods of improving the health of the microbiome of an individual's skin relate to the provision of skin contacting formulations containing beneficial bacteria, postbiotics, metabolites and other microbe components to foster the growth and maintenance of a healthy skin microbiome. One embodiment includes a topical application of Lactobacillus Crispatus to ameliorate skin barrier damage and inflammation using unique combinations of probiotics, prebiotics, postbiotics, and other skin-beneficial ingredients, effectively treating inflammatory skin diseases, such as atopic dermatitis, psoriasis and acne, through the production of tryptophan metabolites that act as AHR agonists.

A method to reduce the likelihood of a dysbiosis of the vaginal microbiome in an individual employing a probiotic method and composition for maintaining a healthy vaginal microbiome, with particular embodiments including a bacterial formulation of at least two live bacteria selected from the group consisting of L. reuteri, L johnsonii and L. crispatus, and at least one prebiotic having glycogen as a component thereof. The bacterial formulation is administered to an individual's vagina in an amount sufficient for the bacterial formulation to generate an amount of tryptophan metabolites sufficient to act as aryl hydrocarbon receptor (AHR) agonists, thereby reducing inflammation in the individual's vagina. Certain embodiments include increasing the production of SCFAs in the individual's gut microbiome, while reducing the production of SCFAs in the individual's vagina and introducing ammonia oxidizing microorganisms to the individual's vagina.
