Monoclonal gammopathy of undetermined significance can progress to multiple myeloma. Applying significance analysis of microarrays, 52 genes, involved in important pathways related to cancer, were differentially expressed between plasma cells from healthy subjects and patients with stringently defined monoclonal gammopathy of undetermined significance / smoldering multiple myeloma and symptomatic multiple myeloma. Unsupervised hierarchical clustering of 351 multiple myeloma and 44 cases of monoclonal gammopathy of undetermined significance and 16 cases of multiple myeloma with a monoclonal gammopathy of undetermined significance history, created two major cluster branches, one containing 82% of the monoclonal gammopathy of undetermined significance cases and 28% of the multiple myeloma, termed monoclonal gammopathy of undetermined significance-like multiple myeloma. Using the same clustering approach on an independent cohort of 213 cases of multiple myeloma revealed 27% with monoclonal gammopathy of undetermined significance-like multiple myeloma which, despite a lower incidence of complete remission, was associated with low-risk clinical and molecular features and superior survival. The monoclonal gammopathy of undetermined significance-like multiple myeloma signature was also seen in patients surviving more than 10 years after autotransplant.

First, to solve the problems of the present invention, the present inventors confirmed the presence of ovarian cancer antigen-specific T cells in the peripheral blood of ovarian cancer patients by using an experimental system that detects combinations of CD4 and IL-4 or IFNγ. Next, using analogue peptides of the core protein MUC16 of the ovarian cancer-associated antibody C125, the present inventors revealed that antigen-specific CD4-positive T cells are present at an average frequency of about 4% in the peripheral mononuclear cells of patients and healthy subjects. Then, the present inventors analyzed the epitope for T cells in the core protein MUC16 of the ovarian cancer-associated antigen CA125, and determined the amino acid sequence FTLNFTITN (SEQ ID NO: 1) to be a shorter epitope.

We present a tool that can enhance the concept of BWS training by allowing natural APAs to occur mediolaterally. While in a supine position in a 90 degree tilted environment built around a modified hospital bed, subjects wear a backpack frame that is freely moving on air-hearings, as a puck on an air hockey table, and attached through a cable to a pneumatic cylinder that provides a load that can be set to emulate various G-like loads. Veridical visual input is provided through two 3-D automultiscopic displays that allow glasses free 3-D vision representing a virtual surrounding environment that may be acquired from sites chosen by the patient. Two groups of 12 healthy subjects were exposed to either strength training alone or a combination of strength and balance training in such a tilted environment over a period of four weeks.

A new combined index of structure and function (CSFI) for staging and detecting glaucomatous damage is provided. An observational study including 333 glaucomatous eyes (295 with perimetric glaucoma and 38 with preperimetric glaucoma) and 330 eyes of healthy subjects is described. All eyes were tested with standard automated perimetry (SAP) and spectral domain optical coherence tomography (SDOCT) within 6 months. Estimates of the number of retinal ganglion cells (RGC) were obtained from SAP and SDOCT and a weighted averaging scheme was used to obtain a final estimate of the number of RGCs for each eye. The CSFI was calculated as the percent loss of RGCs obtained by subtracting estimated from expected RGC numbers. The performance of the CSFI for discriminating glaucoma from normal eyes and the different stages of disease was evaluated by receiver operating characteristic (ROC) curves. The mean CSFI, representing the mean estimated percent loss of RGCs, was 41% and 17% in the perimetric and pre-perimetric groups, respectively (P<0.001). They were both significantly higher than the mean CSFI in the normal group (P<Q.0( )1). The CSFI had larger ROC curve areas than isolated indexes of structure and function for detecting perimetric and preperimetric glaucoma and differentiating among early, moderate and advanced stages of visual field loss. An index combining structure and function performed better than isolated structural and functional measures for detection of perimetric and preperimetric glaucoma as well as for discriminating different stages of the disease.
