Abstract: An ambulatory device for measuring urine flow comprises a portable hand-held container and a handgrip mounted thereto. A flow-measuring device is located in the container, and a means for collecting the data measured by the flow-measuring device is also provided. The parameters of the urine flow in the container are measured by the flow-measuring device and are processed by the aforementioned means for collecting data. The handgrip is pivotally mounted to the container by a double-pivot mechanism for maintaining the container substantially vertical in a number of positions of the handgrip. The flow-measuring device includes a sensor that measures a displacement of an air column related to a variation of pressure due to a variation of a urine level in the container.
Abstract: A method for iteratively decoding a set of encoded samples received from a transmission channel is provided. A data signal indicative of a noise level of the transmission channel is received. A scaling factor is then determined in dependence upon the data signal and the encoded samples are scaled using the scaling factor. The scaled encoded samples are then iteratively decoded. Furthermore, a method for initializing edge memories is provided. During an initialization phase initialization symbols are received from a node of a logic circuitry and stored in a respective edge memory. The initialization phase is terminated when the received symbols occupy a predetermined portion of the edge memory. An iterative process is executed using the logic circuitry storing output symbols received from the node in the edge memory and a symbol is retrieved from the edge memory and provided as output symbol of the node. Yet further an architecture for a high degree variable node is provided.

Abstract: Pancreatic acinar cells contribute to ?-cell neogenesis. Hamsters administered pentadecapeptide of INGAP protein demonstrated a 2-fold increase in the number of extra-islet acinar-associated ?-cell clusters resulting in a 2.8-fold increase in the overall extra-islet ? cell mass as compared to controls. In mammals acinar-to-?-cell differentiation provides an alternate pathway to ?-cell neogenesis; INGAP peptide plays a significant role in this process.

Abstract: A decoding method and system for stochastic decoding of linear codes with the parity check matrix comprising elements of a Galois field is provided. Each encoded sample of a set of encoded samples is first scaled by a scaling factor proportional to a noise level of the set of encoded samples. Each of the scaled encoded samples is then converted into a corresponding probability. For each probability a corresponding probability message is the generated by encoding each probability as a sequence of symbols or bits. Each probability message is then provided to a respective variable node of a logic circuitry for stochastic decoding. The logic circuitry represents a factor graph of the parity check matrix of the linear code.

Abstract: A method and apparatus for lesion or organ definition for the purpose of radiation treatment planning localization and treatment position verification. The apparatus uses a combination of an ultrasound imaging system and a diagnostic imaging system to acquire localization ultrasound images referenced in the coordinate space of the diagnostic imaging system through the use of a position sensing system. The method compares the location of the lesion in the localization ultrasound images with the position of the lesion in ultrasound images taken while the patient lies on the treatment table of a therapy treatment unit, suggests corrective measures to place the lesion in its intended treatment position and executes the correction upon confirmation from qualified personnel.

Abstract: The present invention relates to a method and system for high-speed bandpass serial data communication. A driver receives at least one data signal and generates a bandpass data signal for transmission through a bandpass waveguide interconnect. The bandpass data signal is launched into the bandpass waveguide interconnect using a first adaptor and extracted therefrom after transmission using a second adaptor. A receiver connected to the second adaptor recovers the at least one data signal from the extracted bandpass data signal. A dispersion compensation circuit receives one of the at least one data signal and the bandpass data signal and information indicative of a phase response of the bandpass waveguide interconnect and dispersion compensates the one of the at least one data signal and the bandpass data signal by compensating the phase response of the bandpass waveguide interconnect.

Abstract: Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over-expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.

Abstract: The invention provides novel inhibitors of protein translation initiation and inhibitors of eIF4F activity that can increase chemosensitivity or diminish or reverse chemoresistance in growth transformed cells and thereby reduce hyperproliferative conditions, such as cancer progression, in select patient populations having particular tumor genotypes. The invention also provides methods which target translation initiation controls in growth-transformed cells, such as tumor subtypes with altered expression of a gene activity, including the human akt, bcl-2, eIF4E, eIF4A or PTEN activities, to restore drug sensitivity in vivo in a genotype selective manner. In one aspect, the inhibitors of translation initiation of the invention are rocaglates, i.e., cyclopenta[b]benzofurons, which increases chemosensitivity or diminishes or reverses chemoresistance either alone or in combination, additively or synergistically, with other agents that alter growth or death.
