Thessaloniki, Greece

The Aristotle University of Thessaloniki is among the oldest and most prestigious higher education institutions of Greece. It is the largest university in Greece and in the Balkans. It is named after the philosopher Aristotle, who was born in Stageira, about 55 km east of Thessaloniki. Its campus covers 230,000 square metres in the centre of Thessaloniki, with additional educational and administrative facilities elsewhere.More than 95,000 students study at the Aristotle University, 86,000 in undergraduate programmes and 9,000 in postgraduate programmes. The Teaching and Research Staff number 2,248 people , the Scientific Teaching Staff number 84 and the Special Laboratory Teaching Staff 275 people. They are supported by 309 members of the Special Technical Laboratory for teaching services and the 1028 administrative staff.The language of instruction is Greek, although there are programs in foreign languages and courses for international students, which are carried out in English, French, German, and Italian.

Critical Reviews in Solid State and Materials Sciences | Year: 2010

This review concerns nanoparticles collected in the form of nanopowder or a colloidal solution by laser ablating a solid target that lies in a gaseous or a liquid environment. The paper discusses the advantages of the method as compared with other methods for nanoparticle synthesis, outlines the factors on which the properties of the produced nanoparticles depend, explains the mechanisms and models involved in the generation of nanoparticles by laser ablation, clarifies the differences between nanoparticle generation in gaseous and liquid environments, presents some experimental desigins and equipment used by the several groups for nanoparticle generation by laser ablation, describes the techniques used for tuning the width of the nanoparticles size distribution, and finally presents a few interesting examples of nanoparticles generated by laser ablation. © 2010 Taylor and Francis Group, LLC.

European urology | Year: 2010

Erectile dysfunction (ED) and premature ejaculation (PE) are the two most prevalent male sexual dysfunctions. To present the updated version of 2009 European Association of Urology (EAU) guidelines on ED and PE. A systematic review of the recent literature on the epidemiology, diagnosis, and treatment of ED and PE was performed. Levels of evidence and grades of recommendation were assigned. ED is highly prevalent, and 5-20% of men have moderate to severe ED. ED shares common risk factors with cardiovascular disease. Diagnosis is based on medical and sexual history, including validated questionnaires. Physical examination and laboratory testing must be tailored to the patient's complaints and risk factors. Treatment is based on phosphodiesterase type 5 inhibitors (PDE5-Is), including sildenafil, tadalafil, and vardenafil. PDE5-Is have high efficacy and safety rates, even in difficult-to-treat populations such as patients with diabetes mellitus. Treatment options for patients who do not respond to PDE5-Is or for whom PDE5-Is are contraindicated include intracavernous injections, intraurethral alprostadil, vacuum constriction devices, or implantation of a penile prosthesis. PE has prevalence rates of 20-30%. PE may be classified as lifelong (primary) or acquired (secondary). Diagnosis is based on medical and sexual history assessing intravaginal ejaculatory latency time, perceived control, distress, and interpersonal difficulty related to the ejaculatory dysfunction. Physical examination and laboratory testing may be needed in selected patients only. Pharmacotherapy is the basis of treatment in lifelong PE, including daily dosing of selective serotonin reuptake inhibitors and topical anaesthetics. Dapoxetine is the only drug approved for the on-demand treatment of PE in Europe. Behavioural techniques may be efficacious as a monotherapy or in combination with pharmacotherapy. Recurrence is likely to occur after treatment withdrawal. These EAU guidelines summarise the present information on ED and PE. The extended version of the guidelines is available at the EAU Web site (http://www.uroweb.org/nc/professional-resources/guidelines/online/). Copyright © 2010 European Association of Urology.

Microbial Cell Factories | Year: 2012

This paper gives an overview of the recent advances in engineering the central carbon metabolism of the industrially important bacteria Escherichia coli, Bacillus subtilis, Corynobacterium glutamicum, Streptomyces spp., Lactococcus lactis and other lactic acid bacteria. All of them are established producers of important classes of products, e.g. proteins, amino acids, organic acids, antibiotics, high-value metabolites for the food industry and also, promising producers of a large number of industrially or therapeutically important chemicals. Optimization of existing or introduction of new cellular processes in these microorganisms is often achieved through manipulation of targets that reside at major points of central metabolic pathways, such as glycolysis, gluconeogenesis, the pentose phosphate pathway and the tricarboxylic acid cycle with the glyoxylate shunt. Based on the huge progress made in recent years in biochemical, genetic and regulatory studies, new fascinating engineering approaches aim at ensuring an optimal carbon and energy flow within central metabolism in order to achieve optimized metabolite production. © 2012 Papagianni; licensee BioMed Central Ltd.

Microporous and Mesoporous Materials | Year: 2011

The natural zeolites have already found extensive applications to the environmental remediation and restoration. The most of these applications are based on their ion-exchange properties. This contribution provides a short review of the recent literature concerning the utilization of natural zeolites and their modified forms in the separation, binding and chemical stabilization of hazardous inorganic, organic and radioactive species in soils and aqueous systems. The advantages and eventual disadvantages of the techniques are also discussed. © 2011 Elsevier Inc. All rights reserved.

Current Opinion in Colloid and Interface Science | Year: 2013

Particle tracking microrheology, an emerging experimental technique, which utilizes the Brownian motion of embedded particles to probe local dynamics of soft materials, is presented. Particle tracking microrheology is a powerful technique that enables the measurement of viscoelastic responses in small sample volumes, which are inaccessible to macrorheology and to spatially map structural heterogeneities at a microlevel. Therefore, particle tracking microrheology has considerable potential in food emulsions and gels, since these systems are commonly inhomogeneous. Recent advances and achievements are discussed, including the basic principles, operating regimes and limitations of the technique. The application of the technique in the field of food gels and emulsions to study the evolving dynamics of inhomogeneous at microscale length systems and during sol-gel transition is highlighted. © 2013 Elsevier Ltd.
