Organoleptic and Quality Characteristics of Malagousia Variety, Grapes Fermented with Selected Indigenous Yeast Strains
Commercial Malagousia varietal wines, which are produced in almost all Greek viticultural zones, representa relatively important part of Greek wine activity. This study presents the results of a profile compilation ofvolatile aroma compounds of Malagousia musts fermented under identical conditions with selected yeaststrains. In total, 62 volatile aroma compounds were identified and separated into their chemical classes(aldehydes, higher alcohols, volatile phenols, terpenes, C13-norisoprenoids, lactones, esters, fatty acids,sulphur compounds, other compounds, and other alcohols). Alcohols and higher alcohols, such as cis-hexen-1-ol and geraniol, terpenes like linalool, esters such as ethyl isovalerate, ketones such us betadamascenone,beta-ionone and zingerone, and fatty acids such as geranic acid and phenylacetaldehyde, were found inall the samples. Among them, linalool and phenylacetaldehyde had the strongest effect on the volatilecompound profile of Malagousia wines. The same wine samples were subjected to sensorial analysis by atrained panel of 10 wine tasters, and a statistical analysis of both analyses presents similarities betweenthe two analysis approaches. It is hoped that the results will contribute to a better understanding of thequality potential of the Malagousia variety so as to evaluate possible differences on the basis of the detectedaroma concentrations
Investigating Interoperability Capabilities Between IFC and Citygml LOD 4 – Retaining Semantic Information
Applications of 3D City Models range from assessing the potential output of solar panels across a city to determining the best location for 5G mobile phone masts. While in the past these models were not readily available, the rapid increase of available data from sources such as Open Data (e.g. OpenStreetMap), National Mapping and Cadastral Agencies and increasingly Building Information Models facilitates the implementation of increasingly detailed 3D Models. However, these sources also generate integration challenges relating to heterogeneity, storage and efficient management and visualization. CityGML and IFC (Industry Foundation Classes) are two standards that serve different application domains (GIS and BIM) and are commonly used to store and share 3D information. The ability to convert data from IFC to CityGML in a consistent manner could generate 3D City Models able to represent an entire city, but that also include detailed geometric and semantic information regarding its elements. However, CityGML and IFC present major differences in their schemas, rendering interoperability a challenging task, particularly when details of a building’s internal structure are considered (Level of Detail 4 in CityGML). The aim of this paper is to investigate interoperability options between the aforementioned standards, by converting IFC models to CityGML LoD 4 Models. The CityGML Models are then semantically enriched and the proposed methodology is assessed in terms of model’s geometric validity and capability to preserve semantics

Preoperative CT angiography reduces surgery time in perforator flap reconstruction
The use of perforator flaps in breast reconstructions has increased considerably in the past decade. A disadvantage of the perforator flap is difficult dissection, which results in a longer procedure. During spring 2006, we introduced CT angiography (CTA) as part of the diagnostic work-up in perforator flap reconstructions to visualise each perforator more accuratety. The main objectives were to reduce surgery time and the number of complications. A chart review was conducted 1 year after CTA introduction to investigate if these objectives were met. Materials and methods: Patients with a deep inferior epigastric perforator (DIEP) flap who underwent preoperative analysis through CTA were retrospectively evaluated. The population Results: One hundred and thirty-eight DIEP breast reconstructions were done; 70 underwent preoperative CTA analysis, and 68 had preoperative Doppler investigation. Surgery time in the CTA group was significantly lower (P <0.001) than in the control group, 264 min (SD +/- 62) versus 354 min (SD +/- 83), respectively. There was a tendency for fewer complications in the CTA group compared with the control group. All flaps were successful in the CTA group. In the control group, one flap failed and partial necrosis occurred in three flaps. The differences were not statistically significant. Conclusions: Preoperative CTA in the assessment of vascular anatomy during perforator flap reconstruction was safe and reliable. It helped reduce surgery time, and may prevent the number of postoperative complications.

Tissue microdialysis in critically ill septic patients: associations with sepsis severity and mortality
Increased Prevalence of Anxiety-Associated Personality Traits in Patients with Cushing’s Disease: A Cross-Sectional Study
Background/Aims: Chronic hypercortisolism in Cushing’s disease (CD) hasbeen suggested to contribute to an altered personality profile in thesepatients. We aimed to test this hypothesis and attempted to determinethe effects of disease- and treatment-related factors that mightmoderate an altered personality in CD. Methods: We assessed 50 patientswith CD (74% biochemically controlled) and compared them to 60 patientswith non-functioning pituitary adenomas (NFPA) and 100 age-andgender-matched mentally healthy controls. Personality was measured bytwo standardized personality questionnaires, TPQ (Cloninger PersonalityQuestionnaire) and EPQ-RK (Eysenck Personality Questionnaire-RK).Results: Compared to mentally healthy controls, CD patients reportedsignificantly less novelty-seeking behaviour, including less exploratoryexcitability and less extravagance. On harm avoidant subscales, theypresented with more anticipatory worries and pessimism, higher fear ofuncertainty, shyness with strangers, fatigability and asthenia.Moreover, CD patients appeared to be less extraverted, more neurotic andsocially desirable. CD patients differed from NFPA patients in terms ofhigher neuroticism scores, and NFPA patients did not show alterednovelty-seeking behaviour or extraversion. In the subgroup analysis, CDpatients with persistent hypercortisolism displayed significantly higherfear of uncertainty, fatigability and asthenia, indicating high harmavoidance in total, than those in biochemical remission. Conclusion:Patients with CD showed a distinct pattern of personality traitsassociated with high anxiety in combination with traits of lowexternalizing behaviour. Such personality changes should be taken intoaccount in the diagnosis and treatment of CD patients, as they mightinterfere with the patient-physician communication and/or challenge thepatients’ social and psychological functioning
