METHOD OF PROMOTING CELLULAR HYDRATION BY ENHANCING INTRACELLULAR PERMEATION
A method of promoting increased cellular hydration in a multicellular organism that is capable of intracellular water permeation includes the step of causing the multicellular organism to ingest an aqueous solution that contains an amount of a carbohydrate clathrate component. There is also a step of enhancing the intracellular permeation. The multicellular organism contains aquaporins, and the causing step involves interaction of the composition with the aquaporins. The cellular hydration promoted and caused by the method is corroborated by a test that uses human-aquaporin-expressed frog oocytes. The test uses single cell Xenopus laevis frog oocytes having expressed human aquaporin AGP1 water channels. There is also a beverage composition that increases lifespan in the multicellular organism, and a beverage composition that promotes cellular hydration when ingested by a multicellular organism.

##STR00001## wherein either R.sub.1 is a —Y-Nu group and R.sub.2 is H, or R.sub.1 is H and R.sub.2 is a —Y-Nu group and H, wherein Y is, inter alia, —O—(CH.sub.2).sub.m—, and m is 1, 2, or 3.
Compositions and methods for differential release of 1-methylcyclopropene
A clathrate of 1-methylcyclopropene with α-cyclodextrin, obtained as a solid particulate product, is modified by comminuting, classifying, or both to obtain a modified particulate. When subjected to identical atmospheric disgorgement conditions of humidity and temperature, identical masses of the modified and unmodified particulates exhibit different rates of 1-methylcyclopropene disgorgement. Specifically, we have found that a smaller mean particle size is inversely related to a greater rate of 1-methylcyclopropene release.
Electrophotographic photosensitive member, process cartridge, and electrophotographic image forming apparatus
An electrophotographic photosensitive member, which is suppressed in occurrence of fogging and is excellent in abrasion resistance. In the electrophotographic photosensitive member, an outermost surface layer of the electrophotographic photosensitive member comprises a polymerized product of a composition comprising at least a polyrotaxane and a monomer having a polymerizable reactive group, and a chain molecule of the polyrotaxane has two blocking groups at both terminals thereof, and a (meth)acryloyloxy group of a cyclic molecule of the polyrotaxane forms a bond.
Porous cyclodextrin polymeric materials and methods of making and using same
A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.

Pharmaceutical compositions comprising meloxicam
Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a T.sub.max of meloxicam of 3 hours or less.
MANUFACTURING PROCESS FOR CYCLODEXTRIN DERIVATIVES
A process and equipment assembly for reacting a substituent precursor with a cyclodextrin starting material to provide a raw product comprising a cyclodextrin derivative and 1% or less of an initial amount of the substituent precursor is provided. The process of the present invention provides cyclodextrin derivatives in substantially shorter time and with fewer side products than previous processes that utilize substantially the same starting materials.
METHOD FOR MODIFYING A YARN OR TEXTILE FABRIC
The present invention relates to a method for modifying a textile yarn or fabric by immobilising a cyclodextrin derivative on said yarn or fabric, said process comprising a step (a) of contacting said textile yarn or fabric with said cyclodextrin derivative and with a bridging agent such as 1,2,3,4-butanetetracarboxylic acid, optionally in the presence of a catalyst such as cyanamide,
to obtain a textile yarn or fabric on which the cyclodextrin derivative of formula (I) is immobilised.
