Title: Method for the detection of cytosine methylations
Inventor: BERLIN KURT
IPC: C12Q1/6827
Filed: 2001-10-10
Abstract: A method for the detection of cytosine methylations in genomic DNA is disclosed, whereby genomic DNA samples are firstly reacted with a chemical reagent, whereupon 5-methylcytosine and cytosine react differently and thus display a different base pair relationship in the DNA duplex after said reaction. The pre-treated DNA is then amplified by means of a polymerase and  at least one primer oligonucleotide and the amplified material once again reacted with a chemical reagent as above. The cytosine bases and/or guanine bases remaining in the amplified material after the renewed chemical treatme nt are detected in the final step.

Title: Polymer-cellulose composites having increased fade resistance and process for producing same
Inventor: SACKINGER SCOTT
IPC: B32B27/06
Filed: 2003-04-15
Abstract: Excellent fade resistance and a substantial reduction in whitening can unexpectedly be achieved by adding colorant pigments to polymer-cellulose materials which form the polymer-wood composites, prior to formation of the composites. Then, the outer surface of the polymer-wood composites including the colorant pigments are distressed. The addition of the colorant pigments to the polymer-cellulose materials, combined with the distressing of the surface of the composites formed therefrom, results in an unexpected reduction in the unacceptable level of whitening and/or fading mentioned above which has not taken place in polymer-wood composites which include either a per se colorant pigment addition or which have been subject to a per se surface distressing operation.

Patent CA-2430980-A1 (CA)
Inventor: RITTER DAVID C
IPC: B27N3/06
Filed: 2003-06-04
Abstract: The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a - radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced.
