Systems and methods for predicting the efficacy of a marketing message to generate word of mouth (WOM) are disclosed. A prediction server may generate and distribute surveys to a subset of a target market group. The prediction server may then analyze the survey responses and compare the responses to past responses for marketing messages in similar product or service categories. One or more scores relating to the message's ability to generate WOM may then be computed. These scores may reflect purchase intent, message advocacy, and message amplification of the marketing message. The marketing message may then be refined based on the value of the one or more scores. The prediction server may also access in-market data in order to project volume build or equity build of a promotional item associated with the marketing message.

The methods described herein enable the evaluation of compounds on subjects to assess their therapeutic efficacy or toxic effects. The target of analysis is the underlying biochemical process or processes (i.e., metabolic process) thought to be involved in disease pathogenesis. Molecular flux rates within the one or more biochemical processes serve as biomarkers and are quantitated and compared with the molecular flux rates (i.e., biomarker) from control subjects (i.e., subjects not exposed to the compounds). Any change in the biomarker in the subject relative to the biomarker in the control subject provides the necessary information to evaluate therapeutic efficacy of an administered drug or a toxic effect and to develop the compound further if desired. In one aspect of the invention, stable isotope-labeled substrate molecules are administered to a subject and the label is incorporated into targeted molecules in a manner that reveals molecular flux rates through one or more metabolic pathways of interest. By this method, a comparison between subjects and control subjects reveals the effects of the chemical entity or entities on the biomarkers. This, in turn, allows for the identification of potential therapeutic uses or toxicities of the compound. Combinations of compounds can also be systematically evaluated for complementary, synergistic, or antagonistic actions on the metabolic pathways of interest, using the methods of the present invention as a strategy for identifying and confirming novel therapeutic or toxic combinations of compounds.

The present invention provides a method of effectively measuring risk for therapeutic toxicity of a subject having an autoimmune disorder or cancer and predicting and evaluating therapeutic efficacy of immunosuppressive therapies for autoimmune diseases and cancers before or after starting therapy. The present invention also provides for determining a drug metabolite level of a subject during therapy and measuring periodically the drug metabolite level of a subject on maintenance therapy to ensure treatment compliance and continued therapeutic response by measuring minimal clinical important differences (MCID) in the drug metabolite levels. The present invention also provides for a method to effectively optimize the selection and dose of immunosuppressive therapies of a subject having an autoimmune disease or cancer to improve therapeutic efficacy and reduce therapeutic toxicity prior to starting concomitant biologic therapy and before or after the subject has failed to respond to the at least one immunosuppressive agent.

The invention discloses a real human body three-dimensional modeling method specific to personalized virtual fitting. According to the method, a video is used as input data; and several steps of feature matching, key frame selection, three-dimensional point cloud generation, template mapping, and texture mapping and the like are carried out to obtain a human body surface three-dimensional model. Because of the motion recovery structure technology, the reconstruction process is substantially simplified, the burdens of the data collection people and the collected people can be reduced, and the requirements on the instrument and equipment are reduced. Meanwhile, a precise reconstruction result can be obtained. A complete human body surface model is obtained based on template mapping; and thus the method has high robustness on the human body texture information missing and self-shielding. Therefore, only a plurality of control points need to be marked manually before template mapping from the data input to model output and other process is completed automatically. The model that is obtained based on reconstruction can be applied to the game and animation design, movie and television special efficacy, and personalized virtual fit and the like.

The present invention relates to methods and compositions for reducing Distress Dysfunction by restoring and maintaining homeostatic balance in the neurotransmitter systems underlying the Stress Response and the experience of distress and hedonic tone. Distress Dysfunction refers to the experience of dysfunctional emotional and physical distress that interferes with the individual's quality of life and functioning. A novel understanding of the bimodal opioid modulation of pain, and its impact, through serotonergic, dopaminergic, epinephrinergic, and norepinephrinergic processes, on hedonic tone, leads directly to new generation pharmaceutical formulations that are remarkably safe and effective for the treatment of a wide variety of Distress Dysfunctions, including anxiety, depression, anger, insomnia, mood disorders, eating disorders, sexual problems, pain, substance and behavioral addictions, gastrointestinal disorders, autistic spectrum disorders, attention-deficit and hyperactivity disorders, and other emotional and physical distress disorders. The foundation of this discovery is the power of Receptor Switchers, such as ultra-low-dose and very-low-dose opioid antagonists and GM1 ganglioside attenuators, in blocking acute and protracted excitatory opioid receptor signaling. Co-administration of Receptor Switchers with Endorphin Enhancers, such as specific cAMP PDE inhibitors and excitatory amino acids, is an excellent formulation for restoring healthy homeostatic balance to the endogenous opioid system, using the body's endorphins to reduce emotional and physical distress, and through synergistic and homeostatic processes, restoring positive hedonic tone. The addition of Synergistic Enhancers, such as amino acids, SSRI and SNRI agents, and non-opioid analgesics, as well as Exogenous Opioids, enhances and prolongs these therapeutic benefits. The novel principles discovered by this invention also teach a new generation of safe and effective formulations for the treatment of respiratory conditions, neuropathy, and nociceptive pain.
