Vascular endothelial growth factor (VEGF) and thymidine phosphorylase (TP) are important angiogenic enzymes, inducing new blood vessel formation in many human malignancies. In this study, the immunohistochemical expression of the two molecules was analysed in a series of 121 endometrial carcinomas. VEGF was expressed exclusively in cancer cells, while TP(More)
Postherpetic neuralgia (PHN) is a common cause of chronic pain in the elderly. Antidepressants, anticonvulsants, and opioids may reduce discomfort in many patients, while others have pain intractable to all forms of therapy. We present a novel treatment approach for intractable PHN utilizing percutaneous peripheral nerve stimulation. Two cases are described(More)
We present Constituent Grammatical Evolution (CGE), a new evolutionary automatic programming algorithm that extends the standard Grammatical Evolution algorithm by incorporating the concepts of constituent genes and conditional behaviour switching. CGE builds from elementary and more complex building blocks a control program which dictates the behaviour of(More)
Grammatical Evolution is an evolutionary algorithm that can evolve complete programs using a Backus Naur form grammar as a plug-in component to describe the output language. An important issue of Grammatical Evolution, and evolutionary computation in general, is the difficulty in dealing with deceptive problems and avoid premature convergence to local(More)
STUDY OBJECTIVE To examine the influence of abdominal colectomy with combined general anesthesia and epidural analgesia versus general anesthesia on apoptosis of circulating lymphocytes. DESIGN Prospective, randomized, clinical comparison study. SETTING Tertiary-care general hospital. PATIENTS 40 ASA physical status I and II patients undergoing(More)
Greece has been recently affected by several mosquito borne diseases with the West Nile Virus (WNV) outbreak in 2010 being one of the largest reported in Europe. Currently at the epicenter of an economic and refugee crisis and visited by over 16 million tourists a year the integrated management of diseases transmitted by mosquitoes is a public health and(More)
