Compounds which: (a) bind to a 5-HT1A receptor with an affinity of at least 10 M, (b) bind to a 5-HT1A receptor with an affinity at least 50-fold stronger than the affinity with which the compound binds to an alpha 1-adrenergic receptor, and (c) exhibit 5-HT1A receptor antagonist activity on both pre-synaptic and post-synaptic 5-HT1A receptors, and their stereoisomers, hydrates, solvates and pharmaceutically acceptable salts are useful for the treatment of lower urinary tract disorders in mammals.
摘要:
Piperazine derivatives of formula (I) (Ar, Ar' and B are substituted or unsubstituted aryl or heteroaryl groups, Y = N, CH, C-OH, C-CN or C-CONH2, R = H or lower alkyl, Z = CH2 or CH2CH2, Z' = bond or CH2 or CH2CH2) bind to 5HT1A receptors and are useful for the treatment of neuromuscular dysfunctions of the lower urinary tract. The use of these compounds for the preparation of a medicament for this treatment is claimed, and some of the compounds (Z = CH2, Z' = bond) are claimed per se.
摘要:
An improved method for supporting an underground pipeline (12) in an excavated trench (14) is disclosed. The method involves supporting the pipeline (12) on specially-designed support benches (20) at spaced intervals. The benches (20) are designed to fail when exposed to a predetermined load, which load will be placed on the benches (20) at some point during the backfilling of the trench (14) or when the pipeline (12) undergoes hydrostatic testing. When the benches (20) fail, the fill (24) under the pipeline (12) is compacted and thereby supports the pipeline (12) in lieu of the support benches (20).
摘要:
An implant device for surgical treatment of spinal disc damage or injury is formed as a resilient body comprising porous TiNi; the body is internally mobile such that it resiliently expands and contracts in response to variation in forces applied externally on the body.
摘要:
Powders having contact biocidal properties comprise a polysacharide carrying atomic/metallic silver. The preferred polysaccharide is chitin, although other polysaccharides including chitosan, carboxymethyl celluloses and carrageenans can be used. The chitin may be obtained from deproteinated crustacean shells without demineralisation, thus being admixed with calcium carbonate and other naturally occurring minerals present in the shells, and may be enzyme deacetylated. The powders of the invention can be used as biocidal dusting powders, formulated into pastes, gels, hydrogels, creams, foams and aerosol sprays for pharmaceutical applications, or dissolved to form solutions for coating substrates such as skin, fabrics, glass, leather and paper to give a bactericidal surface. A particular application of such a solution is as a protective, post-wash treatment for workwear in a laundering process. The powders of the invention may be prepared by slurrying a polysaccharide, which is capable of interacting with silver ions and which is in powder form, in a liquid in which the polymer is insoluble, which liquid contains silver ions, filtering off the powder, washing the powder, reducing the silver ions which have interacted with the polysaccharide to atomic/metallic silver, and drying the powder. According to the polysaccharide chosen, the liquid is suitably water or aqueous ethanol. The silver ions may derive from silver nitrate. The reduction of the silver ions which have interacted with the polysaccharide to atomic/metallic silver can be effected photochemically through exposure to light. To hasten the reduction, however, the washed powder is preferably slurried in a solution of an alkali metal halide, irradiated under stirring with natural or artificial light containing an ultraviolet component, and again filtered off and washed, before drying it.
摘要:
A process of removing off-flavors and off-odors, such as caused by trichloroanisole (TCA), from food or beverage products by contacting the food or beverage with one or more aliphatic synthetic polymers so as to sufficiently lower the concentration of the off-flavors and off-odors that they are undetectable by taste or smell. The concentration of the TCA is lowered to about 10 ppt or less.

A porous immobilized ion-exchange material (30) is provided and secured in an opening (34). Also provided is an electrodeionization device incorporating the material (30). A method for subjecting a fluid to electrodeionization, is provided utilizing porous immobilized ion-exchange material (30). A salient feature of the material (30) is that it can be regenerated.
摘要:
An anti-fogging mirror assembly (10) comprises a mirrored sheet (12), a second sheet (16), and a bonding medium (18) adapted to bond together the mirrored sheet (12) and the second sheet (16). The bonding medium (18) has embedded in it a heating pad (20) in the form of an electrical resistance heating element, which, when it is supplied with electrical energy, heats the mirrored sheet (12) such that any moisture on the mirrored sheet (12) is evaporated, and condensation of moisture on the mirrored sheet (12) is prevented. The heating element (20) may be in the form of a polyester substrate printed with a conductive ink, and electrical energy to the heating element (20) may be supplied through upper (68) and lower (26) bus bars. A thermostat (54) may be provided such that when the heating element (20) reaches a predetermined temperature electrical energy is no longer supplied to the heating element (20).
摘要:
The incorporation of multiple branch peptide constructions having activity against HIV (such as those described in WO 95/07929 and WO 98/29443) into liposomes of sufficient size for white blood cell internalisation (e.g. greater than 150 nm and preferably approximately 250 to 400 nm) has been shown to increase the activity of those MBPCs manifold. The liposomes and pharmaceutical compositions containing them are claimed.
