Abstract: Methods and reagents for the capture of primary HIV are provided. A cell lin e expressing CCR5, CXCR4 and CD4 receptors binds and is infected by primary HI V. The cell line contains a marker gene sequence, the marker gene sequence expressed in near linear quantities over at least two orders of magnitude in  response to HIV infection. Primary HIV is amplified to create a primary viru s stock through insertion of an amplicon gene into the receptor expressing cel l line. HIV amplification occurs rapidly and is operative with noninfectious H IV through amplification in the presence of an infectivity complement. The present invention is useful in determining host HIV titer, drug sensitivity,  HIV amplification, gene sequencing and co-receptor utilization.

Patent CA-2337900-A1 (CA)
Title: Precision laser capture microdissection utilizing short pulse length
Inventor: SMITH PAUL D
IPC: G01N1/28
Filed: 1999-07-28
Abstract: Laser capture microdissection occurs where the transfer polymer film is placed on a substrate overlying visualized and selected cellular material from a sample for extraction. The transfer polymer film is focally activated (melted) with a pulse brief enough to allow the melted volume to be confined to that polymer directly irradiated. This invention uses brief pulses to reduce the thermal diffusion into surrounding non-irradiated polymer, preventing it from being heated hot enough to melt while providing sufficient heat by direct absorption in the small focal volume directly irradiated by the focused laser beam. This method can be used both in previously disclosed contact LCM, non contact LCM, using either condenser-side (or beam passes through polymer before tissue) or epi-irradiation (or laser passes through tissue before polymer). It can be used in configuration in which laser passes through tissue before polymer with and without an additional rigid substrate. In its preferred configuration it uses the inertial confinement of the surrounding unmelted thermoplastic polymer (and the overlying rigid substrate) to force expansion of the melted polymer into the underlying tissue target. Utilizing the short pulse protocol, the targeted and extracted material can have a diameter equal to or smaller than the exciting beam.

Abstract: Electropurification of contaminated aqueous media, such as ground water and wastewater from industrial manufacturing facilities like paper mills, food processing plants and textile mills, is readily purified, decolorized and sterilized by improved, more economic open configuration electrolysis cell designs with electrodes comprising a plurality of conductive porous elements in electrical contact with one another. The cells may be divided or undivided, and connected in monopolar or bipolar configuration. When coupled with very narrow capillary gap electrodes more economic operation, particularly when treating solutions of relatively low conductivity is assured. The novel cell design is also useful in the electrosynthesis of chemicals, both organic and inorganic types, such as hypochlorite bleaches and other oxygenated species.
