Thank you very much Scott. Good afternoon and welcome. This is, I think a really exciting time for Precision Therapeutics. We now have four divisions under or soon to under our control, so to our shareholders we’ve got a lot to talk about. First is Skyline Medical that now has both a domestic and foreign division of its own and has been very active in 2018. As such it was a pivotal year. Here are some highlights; we continue to expand our sales efforts not only nationally but worldwide. We hired a new Head of Domestic Sales, expanded our sales force with more experienced personnel, established a European office, and hired a Director of Sales. I want to point out that although we did not hit our projections in 2018, we still had sales of machines and disposables that set new records for Skyline. We signed independent distributors in Canada, several European countries, many in the Middle East, India, Pakistan, Australia, Taiwan just to name a few, and we now have machines in five of the world's seven continents and our efforts continue unabated into 2019. In addition, we formed the TumorGenesis division in 2018 to develop the use of biomarkers to test ovarian tumors and to replace lab rats and mice which are more expensive to use, take longer to get results, and these results are less reliable. We also purchased 25% of Helomics, a bioinformatics company specializing in ovarian cancer. We have been moving along smartly on the development of our new Generation 3 machine, which will be smaller, more compact with fewer moving parts. In addition, this new machine will have a separate attachable backing pump available for purchase to help hospitals with limited vacuum. 2019 has also gotten off to a great start. We will finalize our purchase of Helomics and in the next couple of days we will own 100% of this exciting corporation. We have continued to expand Skyline by widening our sales force to cover more of the world, improved our marketing and our training of hospital personnel to maintain our machines. Our new Generation 3 machine will be out for testing in May and will be available shortly thereafter. Now, let's talk about TumorGenesis. Richard Gabriel, Head of TumorGenesis has not let any grass grow under his feet. TumorGenesis was formed to develop a new, rapid approach for growing and testing ovarian tumors in the laboratory using biomarkers which essentially fools the cancer cells into thinking they're still growing inside the patient and replace the use of lab rats and mice. TumorGenesis has continued to move rapidly signing contracts with developers and suppliers of these biomarkers. These suppliers have built the first biomarker screening kits and sent them to a large U.S. university for evaluations on 14 of the 25 ovarian cancer cell types on behalf of TumorGenesis. In addition, these proprietary media screening kits will be offered commercially worldwide, so that other researchers may grow the ovarian cancer cell themselves and they will want to purchase the TumorGenesis biomarker discovery kits to screen their own samples. Following up on the work done at this university, TumorGenesis will then take these biomarkers found in the first screening and mount them on supports to search for new cancer cell preparation. This protocol will result in the production of the TumorGenesis capture kit. This will bring us one step closer to building tumors outside of the body which will in reality match the patient's own tumor. It's really a groundbreaking research if I do say so myself. Now we come to Precision Therapeutics latest acquisition, Helomics Corporation. As I stated earlier we will own 100% of Helomics in a couple of days. Its corporate mission as stated by our VP of Innovation, Mark Collins, machine learning can discover drugs and make people better and with that single-minded purpose we intend to become the leading artificial intelligence company dedicated to women's cancer. Over the past 20 years, over $200 million was invested in Helomics to build one of the largest databases of ovarian, breast, and brain cancers in the country. By applying our deep learning software to these cancers, we will bring realistic hope to thousands of women with these cancers. Over the next several months, we have already and will continue to enter into collaborations with data sharing agreements with other companies in the field to expand our database on these three cancers. Our deep learning software will help to determine what drug combinations will be most effective for each cancer subtype and help pharmaceutical companies to develop them. To achieve our goals, we have assembled a world class -- really world class Advisory Board consisting of these strategic luminaries; Dr. Bob Murphy, Professor of Biological Sciences, Biomedical Engineering, and Machine Learning at Carnegie Mellon University. Amelia Warner recently built and sold two entrepreneurial companies, prior to that she served as Head of Clinical Pharmacogenomics for Merck Research Laboratories overseeing all pharmacogenomics projects. Marc Malandro, VP of Operations for Science at the Chan Zuckerberg Initiative established and owned by Facebook founder Mark Zuckerberg and his wife Priscilla Chan. And finally Dr. Paul Kornblith, a world renowned Neurosurgeon, Clinician, and Clinical Cancer Researcher. Investors can watch our progress like following our collaboration with business leaders to validate our approach and increase the number of tumors available to Helomics to perform genomics sequencing on. One of our goals is to secure a partner similar to how Foundation Medicine did with Roche in 2016. At that time Foundation had information on 18,000 tumors. We have over 150,000 tumors in our data bank and our job is to mind them as Foundation did. Again really, really exciting stuff. And with that I will pass the call to Bob Myers, our CFO who will now discuss our financial results for the fiscal year-ended December 31, 2018. And then we will open the call for questions. Bob.
