Welcome and thank you for joining today's conference call to discuss the Precision Therapeutics financial results and corporate developments for the quarter-ended March 31, 2019. I'm pleased to report that we have begun 2019 with some notable accomplishments that position Precision for excellence in the coming quarters. With our completion of the Helomics merger, which is now become a wholly-owned subsidiary, and the advancement of TumorGenesis, the precision medicine focus for our company is in full flight. We stand at the forefront of the cutting-edge of personalized medicine in targeting individualized treatments for cancers and the development of drugs specific to a person's genetic propensity to respond the treatment. The use of artificial intelligence in advanced analytics, the mechanism to fool cancer cells into responding to treatments as if they were still in the human body. These are the tools and methods we are employing in advancing our mission at Precision. While we're going about accomplishing our goals, we are creating important alliances with strong partners that we can work with and learn some. We have accomplished much in the first quarter that bears fruit from our Helomics merger and positions us to gain opportunity to monetize our intellectual property and technological superiority. Some examples of these are our announced collaboration between Helomics and Viome to determine role of a gut microbiome in ovarian cancer. We also announced Helomics and National Alopecia Areata Foundation signing a service agreement to provide next generation patient registry for Alopecia Areata research. TumorGenesis and its partner 48Hour Discovery received an Alberta Innovates grant for $250,000 for development of novel cancer treatments in Helomics. And SpeciCare announced the partnership with Helomics will provide CRO and Artificial Intelligence drug development services to SpeciCare for a precision medicine trial. We were thrilled to announce TumorGenesis have identified…

Thank you, Carl, and welcome, everyone. I will now discuss the financial results for the first quarter ended March 31, 2019. Revenue, our revenue for the first quarter of 2019 was $255,241 compared with $411,593 for 2018. This represents a 38% decrease year-over-year. Our revenue included the sale of 7 STREAMWAY systems and disposable supplies. There were 7 sales of STREAMWAY units, 3 domestically and 4 internationally in the three months ended March 31, 2019 compared to 16 sales of STREAMWAY units in the comparable 2018 period. Cost of sales, our cost of sales was $74,000 in the three months ended, March 31, 2019 and $117,000 in the three months ended March 31, 2018. The gross profit margin was approximately 71% in the three months ended March 31, 2019 compared to the same 71% in the prior year. Eventually, we expect increased sales to allow us to achieve volume purchasing. We'll get discounts on both equipment components and our cleaning solutions, which we expect to improve our margins. Operating expense, our operating expenses increased by $179,000 in the three months ended March 31, 2019 compared to the three months ended March 31, 2018. The largest increase in expenditure consisted of $101,000 in research and development, due to producing our next generation STREAMWAY system. General and administrative expenses increased by $256,000 in the three months ended March 31, 2019 compared to the three months ended March 31, 2018. The most significant increases were through legal and accounting expenses relevant to the merger and for audit fees. And our sales and marketing expenses were virtually the same over the comparable quarter period. We turn to our balance sheet. As of March 31, 2019, our cash balance was $1.1 million. Please note that our cash and cash equivalents balance on January 31, 2019 was approximately $380,000. In February of 2019, the company received an additional loan and investment [in equaling $1.3 million] [ph] from the company's CEO, Dr. Carl Schwartz. At March 2019, the company closed on two public offerings, receiving a total net of approximately $2.3 million. The Helomics merger closed on April 4 and the company expects that it will require additional financing to support the need to invest in the precision medicine business. With that, I will turn the call back to Dr. Schwartz. Carl?

After much hard work by a totally dedicated team - a truly dedicated team, our job is to bringing these tools forward to get cancer patients more hope than ever.
