Title: Methods and compositions for determining latent viral load
Inventor: SALAS VIRGINIA
IPC: C12Q1/70
Filed: 2000-04-19
Abstract: The present invention relates to a new HIV stows of a patient called "latent viral load". To measure the "latent viral load." in accordance with a preferred embodiment of the present invention, a population of sample cells is obtained from a desired source, such as an infected patient. The sample cell population is depleted of overtly infected cells and cells harboring active virus, to produce a subset of "resting cells" comprising uninfected and latently-infected cells. This subset is treated with an agent and/or condition that activated the latent virus in the host cell genome and results in a productive infection. The thus-produced infection reflects the "latent viral load" of the host because it reveals the presence of quiescent virus in cells. The latent viral load is useful ie assessing a patient's disease status and the efficacy of hight active antiretroviral therapy and other treatment protocols.

Title: Wavelength tunable external resonator laser using optical deflector
Inventor: SONG JUNG HO
IPC: H01S5/14
Filed: 2002-06-27
Abstract: The present invention relates to an optical deflector driven by an electrical signal, and a wavelength unable external resonator using the same. The optical deflector of a triangle shape, capable of controlling the refractive index of a beam depending on the electrical signal, is positioned between a reflection mirror and a diffraction grating in a Littman-Metcalf mode external resonator or between a lens and the diffraction grating in a Littrow mode external resonator. Thus, even with the reflection mirror and the diffracting grating fixed, the refractive index of the beam generated from a laser diode can be controlled by adjusting the electrical signal applied to the optical deflector, so that beam having a specific wavelength can be focused and the wavelength can be rapidly and consecutively tuned.

Abstract: The utility of the promoter/enhancer region (i.e. regulatory region) of the PSP94 gene in targeting expression of heterologous genes, to the prostate gland was analyzed. Three breeding lines (i.e., line A, line B and line C) of the PSP-TGMAP model described herein were established with constructs containing regulatory regions with or without additional exon/intron sequence of the PSP94 gene. These regulatory regions were operatively linked to the simian virus 40 (SV40) T antigen (Tag, including both the large T and small t antigens). Histopathology evaluation of tumor grade, transgene expression, tumor responsiveness to androgen deprivation and tumor metastatic potential were analyzed and reported herein. This study indicates that regulatory regions (e.g., the promoter/enhancer with exon/intron region) of the PSP94 gene efficiently target the expression of heterologous genes to prostate tissue. Furthermore, the PSP-TGMAP model provides a valuable tool for the analysis of prostate cancer development and for developing new gene therapy vector for the treatment of prostate cancer. Based on this study, mouse PSP94 promoter/enhancer region may be used in the generation of a "shuttle vector" fit for prostate targeting in both mouse CaP model and in human clinical trial.

Title: Extraction bag with support, extraction bag with support containing a material to be extracted, and sheet composite for producing the bags
Inventor: SAKAMOTO MICHIKO
IPC: B65D81/00
Filed: 2001-01-31
Abstract: An extraction bag with support comprises a support member and a bag member which contains a material to be extracted or which is capable of containing a material to be extracted, and is obtained by using a sheet composite on which the support member is arranged and joined along the center line of a water-permeable filtering sheet member, by folding the sheet composite into two and by passing it through a bag-making machine (and, as required, through a filling machine). The head portions of the extraction bag with support are torn apart, the right and left ends are pushed down or up toward the inside to push open the head portions. At the same time, the leg portions continuous with the head portions are folded down to place the extraction bag with support on an extraction container. An extracting solution (hot water) is poured into the material to be extracted that is filled through the portion cut and torn away from the head portions or onto the material to be extracted that has been contained therein, thereby to safely conduct the extraction.

Abstract: A float shoe/collar apparatus (14) and method is disclosed for multi-purpose  use in running a tubular string (11) such as a casing string or liner into a  wellbore and for optimizing cementing operations. In one presently preferred  embodiment, the present invention permits auto filling of the tubular string  (11) as the string (11) is lowered into the wellbore. If desired, circulatio n can be effected through down jets (30) for washing the wellbore as necessary . After the tubular string (11) is positioned, the down jets (30) can be block ed off and up jets (33) opened to thereby direct cement upwardly to optimize cement placement. Check valves (31) can also be activated in accord with the  present invention to prevent flow from the wellbore into the tubular string (11). In one embodiment, the invention comprises an inner member (27) and an  outer tubular member (25). The inner member (27) is movable upon release of shear pins (28) to cause longitudinal movement relative to the outer member (25). The movement of the inner member (27) may close a plurality of downwar d jets (30) and may also open a plurality of upward jets (33) if desired. The apparatus (14) may also be equipped with a set of check valves (31) which ca n be held open on run in, and subsequently activated to thereby automatically close upon cementing to prevent "u- tubing" of fluid back into the casing (1 1).
