20090136952 | MANGANESE SUPEROXIDE DISMUTASE VAL16ALA POLYMORPHISM PREDICTS RESISTANCE TO CHEMOTHERAPEUTIC DRUG CANCER THERAPY - The present invention provides, for the first time, the finding that the manganese superoxide dismutase Val16Ala polymorphism is significantly associated with prognosis for cancer patients treated with chemotherapeutic drug therapy. The alanine allele is a novel biomarker that predicts poor response and poor outcome to chemotherapeutic drug cancer therapy. Conversely, the valine allele predicts a good response and a good outcome to chemotherapeutic drug cancer therapy. Therefore, a genotype assay can be used to determine which alleles a subject is carrying, and subsequently this information can be used to determine if chemotherapeutic drug therapy is appropriate, and to customize therapy according to the patient's MnSOD genotype. | 05-28-2009 |

20120284548 | Zero Indication Forwarding for Floating Point Unit Power Reduction - A method and system for reducing power consumption when processing mathematical operations. Power may be reduced in processor hardware devices that receive one or more operands from an execution unit that executes instructions. A circuit detects when at least one operand of multiple operands is a zero operand, prior to the operand being forwarded to an execution component for completing a mathematical operation. When at least one operand is a zero operand or at least one operand is “unordered”, a flag is set that triggers a gating of a clock signal. The gating of the clock signal disables one or more processing stages and/or devices, which perform the mathematical operation. Disabling the stages and/or devices enables computing the correct result of the mathematical operation on a reduced data path. When a device(s) is disabled, the device may be powered off until the device is again required by subsequent operations. | 11-08-2012 |
