A biosensor for detection of vascular endothelial growth factor (VEGF) hybridization uses an array of parallel capacitors to detect electrochemical binding of circulating VEGF to immobilized anti-VEGF monoclonal half-antibodies (a-VEGF mhAb). Binding of a-VEGF mhAb modulates the threshold voltage of a circuit, changing the impedance of the circuit. An electrode coated with a p-Si substrate enhances the affinity between the VEGF molecules. A fluid cell delivers VEGF samples onto the active surface of the chip. An array of parallel capacitors arranged in an interdigitated pattern detects the VEGF in the fluid. The detector provides an accurately measured and quantifiable rate of change of the VEGF molecules in vivo, providing real time feedback which is used to measure response of the tumor to delivered chemotherapeutic agents and biological response modifiers (BRMs) for the purpose of determining tumor burden and efficacy of the chemotherapy as part of a homeostatic loop for chemotherapy.

An invention that adduces cogent evidence to establish that oxygenated dibenzo-α-pyrones (DBPs and their conjugates), the major bioactives of shilajit (Ayurvedic vitalizer), have their origin, at least partly, in EPA and DHA. Earlier research has shown that, in mammals, C-20 PUFAs are metabolized by oxygenases and other enzymes to produce short-lived prostaglandins, leukotrienes and thromboxanes that bind to specific G-protein-coupled receptors and signal cellular responses, e.g., inflammation, vasodilation, blood pressure, pain etc. But never before it was suggested / shown that C20:5n-3 (and C22:6 n-3) PUFAs, e.g., EPA (and DHA), are transformed into stable aromatic metabolites, DBPs, which elicit a large array of bioactivities in the producer organisms and also control the synthesis and metabolism of arachidonate-derived prostaglandins. The major beneficial effects attributed to EPA and DHA are now found to be largely contributed by DBPs and their aminoacyl conjugates and the dibenzo-α-pyrone-chromoproteins (DCPs). Because of the highly unstable nature of EPA and DHA, when administered, they are metabolized into a large array of uncontrolled products, several of which are systemically undesirable. By contrast, DBPs, because of their stability, perform the biological response modifier (BRM) functions in a directed and sustained way. Many of the biological effects of DBPs described in this invention, were earlier attributed to EPA and DHA,—the precursors of DBPs.
