This invention pertains to a method of low-cost intraoperative all field simultaneous parallel microbeam single fraction few seconds duration 100 to 1,000 Gy and higher dose radiosurgery with micro-electro-mechanical systems (MEMS)-carbon nanotube based microaccelerators. It ablates cancer cells including the mesenchymal epithelial transformation associated cancer stem cells. Microbeam brachy-therapeutic radiosurgery is performed. Microaccelerators are configured for simultaneous parallel microbeam emission from varying angels to an isocentric tumor. Their additive dose rate at the isocentric tumor is in the range of 10,000 to 20,000 Gy/s. It eliminates most tumor recurrence and metastasis which enhances cancer cure rates. It also exposes cancer antigens which induces cancer immunity. Stereotactic breast core biopsy is combined with, positron emission tomography and computerized tomography and phase-contrast imaging. Parallel microbeam brachytherapy preserves normal breast appearance. Migration of normal stem cells from unirradiated valley regions heals the radiation damage to the normal tissue.

A Tat-based vaccine composition comprising at least one antigen coupled to at least one immunostimulatory lentivirus trans-activator of transcription (Tat) molecule wherein the antigen is a cancer antigen an infectious disease antigen or a fragment thereof and methods to treat disease by administering the Tat-based vaccine composition. An additional Tat-based vaccine composition comprising immunostimulatory lentivirus Tat is provided.

A cancer immunotherapy method and composition for treating cancer in a patient comprised of vaccinating a patient with a vaccine comprised of the patient's own malignancy and an immunologic adjuvant, removing primed peripheral blood T lymphocytes from the patient, stimulating the primed T lymphocytes to differentiate into effector lymphocytes in vitro, stimulating the effector T lymphocytes to proliferate in vitro, and infusing the effector T lymphocytes back into the patient.

The present teachings relate to a method of assessing the probability of a major adverse cardiovascular or cerebrovascular event in a human. The method can include measuring a concentration, in a blood-based sample of a human, of a set of analytes, for example, alpha-fetoprotein, cancer antigen 125, glutathione S-transferase, and tissue factor. The method also can include determining a MACCE index for the set of analytes and identifying the human as having an increased likelihood of a major adverse cardiovascular or cerebrovascular event if the MACCE index is greater than zero, or a decreased likelihood of a major adverse cardiovascular or cerebrovascular event if the MACCE index is less than or equal to zero.

Cancer antigens containing mutations in an expressed gene of cancer cells from a cancer patient are identified. Sequences from cancer cells obtained using a parallel sequencing platform are selected by comparing to the patient's normal genes or to normal genes from an HLA-matched individual. Sequences are further selected by identifying an HLA supertype of the cancer patient and selecting for that HLA supertype, sequences that have a particular amino acid at the mutant position and/or corresponding wild-type position in the effected gene. Peptides containing cancer antigens (i.e., mutations—once a mutation is defined, what makes it an immunogen is its ability to induce an immune response) are optionally tested for binding to HLA antigens of the cancer patient. Peptides containing the cancer antigens are evaluated for activating T cells (e.g., helper T lymphocytes and cytotoxic T lymphocytes (CTL)) cell lines from the cancer patient or from an HLA-matched donor. The cancer antigen(s) identified for a cancer patient are used to prepare a cancer vaccine and to treat the cancer patient.

The present invention relates to vaccines that are made in transgenic soybeans for use in humans, animals of agricultural importance, pets, and wildlife. These vaccines are used as vaccines against viral, bacterial, fungal, parasitic or prion related diseases, cancer antigens, toxins, and autologous or self proteins. The transgenic soybeans of the instant invention also can be used for inducing tolerance to allergens or tolerance to autoimmune antigens, wherein an individual shows hypersensitivity to said allergen or has developed autoimmunity to autologous or self proteins, respectively. The invention also relates to prophylatically treating individuals and/or populations prior to showing hypersensitivity to allergens. Other aspects of the invention include using the transgenic soybeans as an oral contraceptive, and the expression of protein adjuvants in transgenic soybeans.

A method of treating cancer in a patient comprises immortalizing B cells collected from the patient by infection with Epstein Barr virus, transforming the cells to a latent stage, culturing the cells in the presence of a cancer antigen, harvesting exosomes released from the cells, administering the exosomes to the patient. Alternatively the harvested exosomes are loaded with cancer antigen.

The invention provides methods for treating with cancer vaccines patients whose cancers undergo clonal evolution. The invention makes use of a series of cancer vaccines to stimulate a patient's immune system to mount both a humoral and cellular immune response against cancer cells as cancer-specific antigens on the cancer cells change by clonal evolution. Vaccines used in the invention are derived from antigens unique to the cancer. In one aspect of the invention, such unique antigens are determined by generating sequence-based profiles of cancer related nucleic acids. In some embodiments, cancer antigens may be identified in sequence-based profiles of exon sequences from a sample suspected of containing cancer cells; in other embodiments in which lymphoid or myeloid cancers are being treated, cancer antigens may be identified in sequence-based clonotype profiles.

The invention relates to a preparation method and the application of a gastric cancer antigen electrogenerated chemiluminescence sensor based on PP<y>-NH2GO-Ag2Se@CdSe, belonging to the field of an electrochemical luminescence sensor. An Ag2Se@CdSe nano pin is taken as an electrogenerated chemiluminescence signal source; the Ag2Se@CdSe nano pin is fixedly loaded on the surface of PP<y>-NH2GO by utilizing the large specific surface area of the PP<y>-NH2GO, so that an antibody capture substrate can be prepared; the luminescent signals of the sensor can be effectively enhanced by the excellent electrical conductivity of the PP<y>-NH2GO. The CA72-4 can be detected according to different electrogenerated chemiluminescence signal intensities for the gastric cancer antigen CA72-4 with different concentrations.
