Item 1. Changes in Control of the Registrant.

         We are filing this amendment to furnish a Descriptive Memorandum
concerning the company and its recent acquisition of Xenomics as an exhibit.

         We completed the acquisition of Xenomics, an unaffiliated California
corporation on July 2, 2004 by issuing 2,258,001 shares of our common stock to
Xenomics' five shareholders in exchange for all outstanding shares of Xenomics
stock (the "Exchange"). The Exchange was made according to the terms of a
Securities Exchange Agreement dated May 18, 2004 ("Exchange Agreement"), which
we filed as an exhibit to a Form 8-K dated May 18, 2004.

         We also completed a private placement of 2,645,210 shares of our common
stock for aggregate proceeds of $2,512,949.50. The sale was made to 17
accredited investors ("Investors") directly by us without any general
solicitation or broker. We filed a Form D with the Securities and Exchange
Commission ("SEC") and the offering is claimed to be exempt from registration
pursuant to Rule 506 of Regulation D under the Securities Act of 1933, as
amended.

         As part of the Acquisition, we:

         o        redeemed 1,971,734 pre-split shares (the equivalent of
                  218,862,474 post-split shares) from Panetta Partners Ltd., a
                  principal shareholder, for $500,000 or $0.0023 per share.

         o        amended our articles of incorporation to change our corporate
                  name to "Xenomics, Inc." and to split our stock outstanding
                  prior to the redemption 111 for 1 (effective July 26, 2004).

         o        entered into employment agreements with two of the former
                  Xenomics shareholders and a consulting agreement with one of
                  the former Xenomics shareholders.

         o        entered into a Voting Agreement with the Investors, the former
                  Xenomics shareholders and certain principal shareholders.

         o        entered into a Technology Acquisition Agreement with the
                  former Xenomics shareholders under which we granted an option
                  to the former Xenomics holders to acquire Xenomics technology
                  if we fail to apply at least 50% of the net proceeds of all
                  financing we raise to the development of Xenomics technology
                  during the period ending July 1, 2006 in exchange for all of
                  our shares and share equivalents held by the former Xenomics
                  holders at the time such option is exercised.

         Each of the above agreements is filed with this report and the above
summary is qualified by reference to the complete documents.

         As a result of the above transactions, we have 15,588,737 shares
outstanding.

         We appointed L. David Tomei, Samuil Umansky, Gary Jacobs and Donald
Picker to be directors according to the terms of the Voting Agreement and Mr.
Tomei was appointed Chairman of the Board. Samuil Umansky was appointed
President and Chief Scientific Officer and Christoph Bruening remains Secretary
and Treasurer.

                                       2


Item 2.  Acquisition or Disposition of Assets.

         See Item 1. above for a description of the material terms of the
Exchange Agreement under which Xenomics became our wholly owned subsidiary.

         The terms of the Exchange Agreement, including the relative number of
our shares to be issued to the holders of Xenomics shares was determined by arms
length negotiation between our management and that of Xenomics. We intend to
continue utilizing the assets of Xenomics in their efforts to develop diagnostic
tests utilizing transrenal nucleic acids for infectious diseases, prenatal
diagnosis, cancer detection and transplantation compatibility.

Item 5.  Other Events and Required FD Disclosure.

         We adopted a 2004 Stock Option Plan which is filed as an Exhibit to
this report. We issued options to acquire 3,750,000 shares of our common stock
to officers and consultants for $1.25 per share.
