Abstract: The treatment of an estrogen sensitive condition by the administration of a selective estrogen receptor modulator is improved by additionally administering a progestationally active compound to the recipient. The additional agent can express both progestational and androgenic activity or an androgenically active material can be employed, if desired. Additionally, clomiphene in an array of isomeric ratios (EN:ZU) can be used alone for prevention of osteoporosis, maintenance of a healthful blood lipid profile, and prevention of breast tumors, or to sustain amenorrhea.

Abstract: A microarray device for the analysis of biological samples is provided. The device includes a liquid permeable layer having a plurality of microregions, each including a plurality of probe-labeled microbeads embedded in the liquid permeable layer. The microbeads in a given microregion include a plurality of the same target probes on their surfaces. The target probes are capable of specifically binding to one or more particular target molecules (e.g., nucleic acid, polypeptide, small molecule antigen). The device typically has the capability of inducing a sample solution to move through the liquid permeable layer under the influence of an applied voltage. Kits which include the device and methods of simultaneously detecting a plurality of different target molecules in a sample solution are also provided.

Abstract: A method of female contraception involves administering a combination of estrogen and progestin continuously for more than a year in which the daily amounts of estrogen and progestin are equivalent to about 5-35 mcg of ethinyl estradiol and about 0.025 to 10 mg of norethindrone acetate, respectively. The advantages include lack of menstrual bleeding, less patient anemia, less total exposure to medication when compared to a 35 microgram (low dose) containing oral contraceptive, reduced risk of endometrial cancer, higher compliance rates and more lifestyle convenience for patients who desire less uterine bleeding each year or longer.

Abstract: A method for intracellular electro-manipulation is provided. The method includes applying at least one ultrashort electric field pulse to target cells. The ultrashort electric field pulse has sufficient amplitude and duration to modify subcellular structures in the target cells and does not exceed the breakdown field of the medium containing the target cells. The amplitude and duration of the ultrashort electric field pulse are typically insufficient to substantially alter permeability of the surface membranes of the target cells, e.g., by irreversibly disrupting the cell surface membranes. An apparatus for intracellular electro-manipulation is also provided. The apparatus includes a pulse generator capable of producing an ultrashort electric pulse output and a delivery system capable of directing the electric pulse output to target cells.

Abstract: Mono- and di-iodinated nonoxynol-9-derivatives and methods for their use are disclosed.

Abstract: Treatments in which a progestational corticoid active compound is administered are improved by additionally administering a selective estrogen receptor modulator.

Abstract: Infection of human fibroblast cells with human cytomegalovirus (HCMV) causes down regulation of cell surface expression of MHC class I. The present invention is directed to a mutant with a 9-kb deletion in the S component of the HCMV genome (including open reading frames IRS1-US9 and US11) which failed to down regulate class I heavy chains. By examining the phenotypes of mutants with smaller deletions with this portion of the HCMV genome, a 7-kb region containing at least 9 open reading frames was shown to contain the genes required for reduction in heavy chain expression. Furthermore, it was determined that two subregions (A and B) of the 7-kb region each contained genes which were sufficient to cause heavy chain down regulation. In subregion B, the US11 gene product is involved. It encodes a endoglycosidase H-sensitive glycoprotein which is intracytoplasmic, similar to the adenovirus type 2 E3-19K glycoprotein which inhibits surface expression of class I heavy chains.

Abstract: A method of female contraception involves administering a combination of estrogen and progestin for 60-110 consecutive days in which the daily amounts of estrogen and progestin are equivalent to about 5-35 mcg of ethinyl estradiol and about 0.025 to 10 mg of norethindrone acetate, respectively. The advantages include less menstrual bleeding, less patient anemia, less total exposure to medication, higher compliance rates and more lifestyle convenience for patients.

Abstract: Cellophane wrapping (CW) of hamster pancreas induces proliferation of duct epithelial cells followed by endocrine cell differentiation and islet neogenesis. Using the mRNA differential display technique a cDNA clone expressed in cellophane wrapped but not in control pancreata was identified. Using this cDNA as a probe, a cDNA library was screened and a gene not previously described was identified and named INGAP.

Abstract: The diagnostic interpretation of mammographic films is enhanced by administering to the women undergoing the procedure an effective amount of a gonadotropin releasing hormone antagonist or other inhibitor of ovarian steroid production or action on the breast thereof and effecting the mammogram before the effect of the antagonist or other inhibitor has dissipated.

Abstract: A growth such as a tumor, hypertrophied tissue or cyst is biopsied or more completely excised subsequent to the administration of an effective amount of a gonadotropin releasing hormone analog or other inhibitor of ovarian steroid production or action.

Abstract: A method of treating an ovarian estrogen dependent condition such as endometriosis, uterine leiomyomata, PMS or DUB involving the administration of gonadotropin releasing hormone analog and the administration of antiprogestin, which will provide a therapeutic method for long term treatment without rapid loss of bone density, as occurs using GnRH analogs alone.

Abstract: A regimen for the therapeutic management of a gonadal-steroid dependent condition in a mammal constitutes reducing the estrogen supply thereof by means of administration of a GnRH antagonist in an amount effective to inhibit proliferation of endometrial tissue without substantially stopping the production of endogenous estrogen. A method of determining whether the reduced estrogen supply in an individual is such that the concentration of estradiol has been suppressed to an optimized level appropriate to the therapeutic management of the gonadal-steroid dependent condition such as endometriosis in that individual by the administration of a GnRH antagonist at a given dosage level involves titering the dosage, e.g., by conducting a progesterone challenge test and optimal regimen doses of a GnRH antagonist.

Abstract: The invention provides compositions and methods for use in detecting benign prostate hyperplasia (BPH) and for differentiating BPH from normal prostate tissues and prostate cancer. Disclosed are monoclonal antibodies (MAbs) directed against a highly restricted biological marker of BPH, hybridoma cells secreting such MAbs and various methods for making and using BPH-specific antigens and antibodies, including methods and kits for the detection of BPH antigens and the diagnosis and therapy of BPH.

Abstract: A method for minimizing menstrual bleeding irregularities in individuals using progestin-only pharmaceutical preparations, such as contraceptives, is disclosed.

Abstract: Improved contraceptive compositions are disclosed which comprise a spermicide or virucide, a polymeric delivery component and optionally a cosmetic ingredient. The improvement is directed to the use of certain hydrophobically modified polysaccharides as the polymeric delivery component. Quite advantageously, the hydrophobically modified polysaccharides of the present invention can alter sperm motility. Moreover, the hydrophobically modified polysaccharides can provide reduced irritation potential when used in combination with spermicides such as, for example, nonoxynol-9, which may reduce the potential for infection of sexually transmitted diseases such as HIV and herpes.

Abstract: A method of female contraception which is characterized by a reduced incidence of breakthrough bleeding after the first cycle involves monophasicly administering a combination of estrogen and progestin for 23-25 consecutive days of a 28 day cycle in which the daily amounts of estrogen and progestin are equivalent to about 5-35 mcg of ethinyl estradiol and about 0.025 to 10 mg of norethindrone acetate, respectively and in which the weight ratio of estrogen to progestin is at least 1:45 calculated as ethinyl estradiol to norethindrone acetate.
