The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (“dsRNA”), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.

The present teachings provide methods for diagnosing biological conditions, including cancer. In some embodiments, a test sample is collected from a subject such as a clinical patient, wherein the test sample comprises background tissue and may or may not contain cells from a tissue of interest. Observation of a target miRNA normally present in a tissue of interest, but collected in an anatomical location ectopic to the tissue of interest, can be indicative of a biological condition. The present teachings further provide exponential amplification techniques applicable to performing these analyses.

Systems and methods for localizing the position of a wireless device using a plurality of coordinated highly directional or adaptive antennas to detect signals from the wireless device. Because of the directional nature and / or adaptive processing of the antennas, off-angle multipath signals resulting from reflection and scattering as the wireless signal propagates through a cluttered environment are rejected by the antennas and processing. As a result, the antennas pass primarily direct path signals from the wireless device to the location estimator. The time of arrival of the signal and the angle of arrival at each antenna are used to in the location estimator to calculate the position of the wireless device. Various robust inversion techniques may also be applied to the data to minimize the effect of residual multipath-corrupted detections. Furthermore, the systems and methods include specialized wireless devices that provide locating signals and signals related to the biological condition of their owner.

A biological condition evaluation apparatus determines a symptom of a heart abnormality based on at least one index calculated from a heartbeat interval and / or a pulse interval. The apparatus determines whether it is in a referential period where an amount of change in the index is comparatively small. The apparatus determines whether a plurality of conditions are satisfied or not in an evaluation period set after the referential period. One condition is that an amount of change in the index in the evaluation period is greater than that observed during the referential period. Another condition is that a rate of change in the index is equal to or greater than a predetermined threshold value. The apparatus determines that there is a symptom of a heart abnormality, when both the conditions are satisfied.
