Abstract: Methods for the treatment of cutaneous vascular conditions and cutaneous proliferative conditions are provided. The methods employ topical administration of mammalian target of rapamycin (mTOR) inhibitors such as sirolimus (rapamycin) and everolimus. Conditions treatable by the disclosed methods include venolymphatic malformations, acne, acne rosacea, periorificial dermatitis, acne vulgaris, cutaneous capillary malformation-arteriovenous malformation (CM-AVM) syndrome, RASopathies, Langerhans cell histiocytosis, non-Langerhans cell histiocytosis, scars, hypertrophic or keloidal scars, Proteus syndrome, PIK3CA-related overgrowth spectrum (PROS), PTEN hamartoma tumor syndromes, cutaneous malignancies and tumors associated with PI3K/AKT/mTOR mutations, keratodermas, acanthosis nigricans, Birt-Hogg-Dubé syndrome, Brooke-Speigler syndrome, cylindromas, and epidermal nevi.

Abstract: Photographic elements particularly adapted for forming direct-positive images are disclosed in which a radiation-sensitive core-shell emulsion layer and a silver halide emulsion layer incapable of forming a surface latent image within the direct-positive exposure latitude of the first emulsion layer and containing a grain population capable of internally trapping photolytically generated electrons are both present. The photographic elements are capable of exhibiting increased covering power, greater maximum density, and increased speed.

Abstract: Blended emulsions for use in forming a direct-positive image are disclosed. The emulsions are comprised of a first, radiation-sensitive core-shell grain population having a relatively low coefficient of variation and a second, substantially smaller size grain population capable of internally trapping photolytically generated electrons. Photographic elements incorporating the blended emulsions exhibit improved covering power and can exhibit enhanced speed.

Abstract: Photographic elements are disclosed containing a hydrophilic colloid layer hardened with a compound having the structural formula:XCH.sub.2 CH.sub.2 SO.sub.2 Q(OQ).sub.m SO.sub.2 CH.sub.2 CH.sub.2 Xwherein X in each occurrence is halogen, Q is an aliphatic or phenyl substituted aliphatic divalent hydrocarbon radical having from 1 to 6 aliphatic carbon atoms and m is an integer of from 0 to 3 inclusive. The hardener also serves as an anti-foggant in photographic applications. Preferred are novel hardening and anti-fogging compounds having the structural formula: ##EQU1## in which X is halogen and R is hydrogen, phenyl or alkyl having from 1 to 6 carbon atoms.

Abstract: Photographic elements are disclosed containing a hydrophilic colloid layer hardened with a compound having two vinylsulfonyl radicals coupled through a divalent hydrocarbon radical chosen from the group consisting of (1) an aliphatic radical having from 1 to 6 carbon atoms, (2) --X--Y--X-- in which X is an alkylene group having 1 or 2 carbon atoms and Y is a phenylene group and (3) a phenyl-substituted methylene group. The compounds may be utilized generally in hardenable hydrophilic colloid compositions. Except for those compounds incorporating an alkylene divalent hydrocarbon radical, the hardeners are new compounds. .Iadd.
