Siga Resources Inc (SGAE)

Siga Resources Inc recently announced that Siga has come to an agreement with Big Rock Resources Ltd. whereby the two companies will develop the Lucky Thirteen gold placer claim under a 50/50 joint venture.

Big Rock Resources Ltd. (1BR.F, ISIN CA0894851066, WKN A1JJYB www.bigrockresources.com) has agreed to fund the initial evaluation program for $400,000 USD, and provide funding up to $8.5 million USD to place the property in full production.

The partners will operate Lucky Thirteen under a Joint Venture company, Lucky 13 Mining Company Ltd., owned 50/50 by Siga and Big Rock. Lucky 13 Mining Company Ltd. will be the operator.

Siga has already secured the initial operating permits for the necessary rail crossing and initial test mining. Siga is currently constructing the washing and initial process plant to be used in the evaluation program.

Siga's President Ed Morrow said that "Siga is most pleased to have Big Rock Resources as a Joint Venture Partner. The combined power of the partnership will facilitate the rapid development of a production operation at Lucky thirteen."

Siga Resources Inc, founded in 2007, is based in South Lake Tahoe, California. Siga is a mineral resource exploration and development company. Siga's strategy targets properties that have the potential for near term production and early positive cash flow. Siga's general geographical interest is North and South America.

Gold specimens are sometimes artistically stunning and a good investment as well. After all, it is gold, which never seems to lose its value. Good natural specimens are more expensive than their actual weight value. This is to be expected as good gold crystals are somewhat scarce (most are disolved, crushed, or melted down as part of the mining process) and the only justification for preserving a specimen is the expectation that it will bring a higher price in its natural state.

Power3 Medical Products, Inc. (PWRM.OB)

Power3 Medical is a leading edge biotechnology company engaged in the early detection, monitoring, and targeting of diseases through the analysis of proteins. This dynamic team utilizes proteomics in the discovery of protein biomarkers, drug pathways, and mechanisms of disease.

Power3 Medical Products, Inc. strives to become the premier biotechnology company specializing in the commercialization of proteomics IP for the diagnosis and treatment of disease by using cutting edge technologies, world class quality procedures and superior research methodologies. The Company will be guided in all of its dealings with its customers, partners, shareholders, associates and investors by the philosophy of best practices.

Power3 Medical Products, Inc uses the NuroPro Blood Test as diagnostic tool for the early detection of Neurodegenerative diseases. The analysis is designed as a tool for physicians to diagnose various degenerative diseases of the brain and nervous system. The test involves monitoring the concentration of 59 proteins in blood serum to accurately detect and distinguish between Alzheimer's disease, ALS (Lou Gehrig's disease), and Parkinson's disease. Early detection of these diseases would allow physicians to intervene at an early stage to delay disease progression, potentially allowing patients to outlive their debilitating symptoms.

With Parkinson's disease, the substantia nigra becomes severely depleted of dopamine and the pathways become disrupted. As a result, there are abnormalities of movement, involving one or more of the following:

*Tremor. This is an involuntary rhythmic shaking in an extremity (like an arm or leg), or in the face. A Parkinson's tremor is worst at rest and gets better when the extremity is moved; it often disappears during sleep. In the hand, the thumb may move back and forth against the other fingers - Parkinson called this motion 'pill rolling'.

*Bradykinesia. This sounds like numbness after watching an episode of The Brady Bunch, but in fact it's a medical term meaning slowness of movement. People with bradykinesia seem to freeze: they have trouble initiating movements and they're slow in changing position. Their voice also sounds monotonous, and they have a fixed, staring, unblinking expression. They stoop, and when they walk they shuffle.

*Muscular rigidity. Muscles - especially in the arms, shoulders and neck - become stiff, rigid, and resistant to being passively moved. They may move in a series of ratchet-like steps: this is called 'cogwheel rigidity'.
