599 results about "Sterility" patented technology

Sterility is the physiological inability to effect sexual reproduction in a living thing, members of whose kind have been produced sexually. Sterility has a wide range of causes. It may be an inherited trait, as in the mule; or it may be acquired from the environment, for example through physical injury or disease, or by exposure to radiation.

Nucleotide sequences mediating male fertility and method of using same

Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.

Bioreactor for organ reconstruction and augmentation

Bioreactors are used in neo-organ production to allow for an appropriate environment for the maintenance of healthy culturing conditions from pre-wetting to shipment of the neo-organ. The closed system “all-in-one bioreactor” is designed to allow for minimal exposure of the scaffold to the open air in order to maintain sterility. The design allows for the same container to be utilized for sterilization, pre-wetting, cell seeding, medium exchange, and shipment. The “all-in-one” bioreactor also remains completely closed after the urothelial cell seeding step to the implantation at the clinical site. This allows for sufficient time for release testing to occur so the neo-organ can be implanted into the patient.

Adjuvant immune therapy in the treatment of solid tumors through modulation of signaling pathways following engagement of humoral and cell mediated responses

The invention combines a novel combination with two especially important aspects: first, the invention proposes to simultaneously stimulate response in white blood cells and a patient's tumor cells with a mitogen-challenging compound, preferably a lectin, in the preferred mode the selected lectin being phytohemagglutin ("PHA"), and second, to generate heat shock protein. A method of treatment is set out. The method of manufacturing proposed utilizes a system calculated to better insure sterility and streamline production of the cytokine modulator. A method of testing in conjunction with the therapy is also claimed utilizing clinical assessment of disease activity, patient performance status, and quality of life questionnaire. Should efficacy of a treatment fall off, particularly because of mutation or adaption, the composition and method may be re- applied. The invention is not limited to humans, but is also applicable to mammals. The composition is usable as a stand-alone composition, but preferably is used in conjunction with standard therapy such as radiation, chemotherapy or surgery, particularly surgical therapy, and in conjunction with the administration of cystine, as later defined, to enhance immune system competency.
