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.

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.

Mobile consumer devices are used to communicate with consumer medical devices to either provide update data to the consumer medical device or to obtain data from the consumer medical device. Some data is used to evaluate performance and operation of the medical device or a biological condition of the living being that is being treated with the medical device. Other data is used to calibrate and update the consumer medical device or to enable or disable certain functionality of the medical device. Communications between the medical devices and mobile consumer devices can be performed automatically or on demand, as initiated by a user, a third party, or in response to predetermined conditions detected by the devices.

The present invention provides kits, apparatus and methods for determining a biological condition in a mammalian subject, the method includes incubating a specimen from a patient with at least one composition in a kit for a predetermined period of time to form at least one reaction product, when the subject has said biological condition, and receiving an indication of the at least one reaction product responsive to at least one reporter element in the kit thereby providing the indication of the biological condition in the subject.

The present provides a carrier molecule for transporting a polyanioic macromolecule such as a nucleic acid across a biological barrier of a cell. The carrier has a biocompatible backbone polymer with two or more polycationic polymer fragments covalently linked. In one embodiment, the backbone polymer is polyethylene glycol (PEG) and the polycationic polymer is polyethylenimine (PEI). The copolymer carrier molecule can be complexed with a polyanionic macromolecule such as a nucleic acid (NA). The NA/copolymer complex is stable in biological conditions by forming a special coreshell-like micelle structure. The nucleic acid can be rapidly released from the complex when biodegradation linker are used to bind the polycationic polymer fragments to the polymer backbone. The carriers and complexes of the invention can be used tin methods of delivering the polycainonic macromolecules to cells both in vitro and in vivo.

A system for monitoring strain as an indicator of biological conditions, such as spinal fusion, glucose levels, spinal loading, and heart rate. The system includes an inter-digitated capacitor sensor, and RF transmitter, and an associated antenna, all of which are microminiature or microscopic in size and can be implanted in a biological host such as a human or animal. An inductively coupled power supply is also employed to avoid the need for implantation of chemical batteries. Power is provided to the sensor and transmitter, and data is transmitted from the sensor, when an external receiving device, such as a handheld RF ID type receiver, is placed proximate the location of the implanted sensor, transmitter and inductively coupled power supply. The implanted sensor, transmitter and inductively coupled power supply can be left in place permanently or removed when desired.

Individualized responsive dosing dietary supplement systems, compositions, methods of dosing, and processes of producing the same, which allow a consumer to generate individualistic biological responses/effects. More specifically, a dietary supplement system for generating individualized biological conditions/responses which utilizes ultra-low dosage amounts of vitamins, minerals, amino acids, co-enzymes, and/or other nutrients in a bio-active delivery system which preferably avoids first pass metabolism, such that an individual may take multiple doses of the same or different dietary supplement based on varying desired biological response within each 24 period is also disclosed.

Administration of low molecular weight (10,000-20,000 Daltons, or lower) pectins, particularly modified citrus pectins (MCP), like PectaSol-C reduces galectins-3 levels in vivo. Reduction of galectin-3 levels by MCP inhibits inflammation, inhibits fibrosis formation in organs and tissues, and inhibits cancer formation, progression, transformation and metastases. The reduction in circulating, serum and cellular galectin-3, inherently resulting from the administration of MCP, provides benefit over a spectrum of biological conditions, as evidenced by in vivo trials.

There is a need for providing a vehicular music replay system that can allow a car user to select a music source appropriate to the user's character or biological condition even from genres unknown to the user, allow even a first music source to be felt suited for the user, and consequently enhance an emotion about encounter with an unknown music source. The system stores music sources to be replayed in music source databases in association with applicable user state data reflecting a user state containing at least one of a user character, mental condition, and physical condition. The system retrieves a music source corresponding to the current user state acquired in a car. During the retrieval, a higher retrieval priority is provided for a music source having a lower replay history in the past.
