Title: Tamper-indicating resealable closure
Inventor: BONENFANT DANIEL M
IPC: B65D75/58
Filed: 2005-07-21
Abstract: A tamper indicating, resealable closure for a package includes first and second film layers releasably adhesively joined together such that the first and second film layers are at least partially separable when the second film layer is pulled away from the first film layer. The first film layer includes first and second tear lines formed thereon to define first and second panel sections respectively.

Title: Reversibly immortalised olfactory ensheathing glia and their use to promote neuronal regeneration
Inventor: MORENO FLORES MARIA TERESA
IPC: A61K48/00
Filed: 2004-07-19
Abstract: The present invention is based on the capacity of the Olfactory Ensheathing Glia (OEG) to foster axonal regeneration in the adult mammalian central nervous system (CNS). This specific capacity is probably due to a combination of several factors, such as the molecular composition of cellular membrane and/or the capacity to secrete some molecules; combined with the capacity to reduce glial scar and accompany new growing axon in the damaged CNS. We have developed immortalised cell lines from primary human OEGs. The cells were cultured from post-mortem human tissue from donors and immortalised using a reversible system. Some of these OEG human clonal cell lines were selected by their ability to promote axonal regeneration from adult rat retinal ganglion neurons in a similar fashion to primary OEGs. These cell lines, alone or in pharmaceutical compositions comprising these cells, may be used to repair neuronal damage in the CNS.

Patent CA-2546555-A1 (CA)
Inventor: PIEDE DAVID
IPC: H01L31/0392
Filed: 2004-11-17
Abstract: A silicon-based IR photodetector [20] is formed within a silicon-on-insulator (SOI) structure [22] by placing a metallic strip [30] (preferably, a silicide) over a portion of an optical waveguide formed within a planar silicon surface layer [28] (i.e., "planar SOI layer") of the SOI structure, the planar SOI  layer comprising a thickness of less than one micron. Room temperature operation of the photodetector is accomplished as a result of the relatively low dark current associated with the SOI-based structure and the ability to use a relatively small surface area silicide strip to collect the photocurrent. The planar SOI layer may be doped, and the geometry of the silicide strip may be modified, as desired, to achieve improved results over prior art silicon-based photodetectors.

Title: A process for producing biodiesel from renewable oil under lipase catalysis in an organic medium reaction system
Inventor: WANG LI
IPC: C07C69/24
Filed: 2004-11-29
Abstract: This invention provides a new process for producing biodiesel from oils and fats catalyzed by lipase in organic medium reaction system. In this process, a short chain alcohol ROH is acyl acceptor, some organic relatively hydrophilic solvents with no negative effect to the reactivity of the lipase act as reaction medium, the oils and fats catalyzed by lipase is a feedstock, transesterification happens and biodiesel is obtained. In the process of this invention, the oils and fats feedstock can be nearly substantially converted to biodiesel and the by-product glycerin, the yield of the biodiesel is up to 94%. These new type organic medium reaction systems may promote the solubility of the short chain alcohol such as methanol in the oils and fats, and may dissolve part of the by-product glycerin, consequently, they can remarkably enhance the lipase reactivity, shorten enzymatic reaction time and prolong the use life of the lipase.
