The Technological Educational Institute of Thessaly or TEI of Thessaly Θεσσαλίας, Technologikó Ekpaideutikó Idryma Thessalias) is a Greek public educational institute that provides Higher Tertiary education in the city of Larissa and in the region of Thessaly.The TEI of Thessaly was established as a tertiary education institution in 1983 along with all Greek Technological Educational Institutes. In 2001 the TEI of Thessaly was established as a Higher Education institution, in compliance with the Bologna declaration. Wikipedia.

All aromatic plants emit volatile substances into the environment either during their life or during the decomposition process. During decomposition, these volatile constituents affect the top soil microflora and the nutrients recycle process. Lavandula stoechas is a perennial aromatic shrub, rich in aromatic substances which can be found abundant across the Mediterranean. The aim of the present study was to investigate the essential oil degradation during decomposition process of L. stoechas and how the essential oil major compounds are released during this process. Fresh leaves and flowers of lavender were used for this study using the litter bag technique. The essential oil content of the initial plant was 1.46% dw and after seventeen months period dropped at 0.06%. There were no differences in oil degradation among the different experimental sites. Most of the essential oil compounds had disappeared after a year. However, the most toxic compounds in the plant material still remained after seventeen months. © 2010 Elsevier Ltd. Source

The Pulsatility Index (PI) was quantified for the first time in the human conjunctival pre-capillary arterioles in vivo. In 30 arterioles with diameters ranging between 6 and 12 μm, from 15 healthy humans, peak to peak velocity ranged from 0.2 up to 4.8 mm/s with a mean value equal to 1.4 ± 0.2 (SE) mm/s. The PI ranged from 0.4 to 1.5 and the overall mean value was 0.8 ± 0.1 (SE). The linear correlation between PI and diameter was practically zero (Spearman's correlation coefficient, rs ≈ 0) for the range of arteriolar diameters examined here. In this work a first step was made towards the complete PI mapping of the human carotid arterial tree. © 2016. Source

The average resistive index (RI) as a function of the average vessel diameter (D) was studied in the human carotid arterial tree. Data were used from previously published research measurements taken from 505 different vessels of 371 healthy humans. When the RI from the carotid arteries was included in the data set the standard trend lines did not give efficient fits. However, when only data from the eye were used, the Neperian logarithmic function gave a best fit with a correlation coefficient r= 0.99 and an absolute relative error less than 2.6%. This logarithmic model could be proved a valuable tool for both basic research and clinical practice in the human eye. © 2013 Elsevier Inc. Source

Wall shear stress (WSS) is a very important hemodynamic parameter implicated in many physiological and pathological phenomena. In order to study these phenomena, it is more convenient to use in vitro models before testing on animals and humans. Dynamic in vitro cerebrovascular models are considered capable of simulating the in vivo hemodynamic conditions, but only few of them seem to meet the criteria for this task. It is now clear that in the human eye microcirculation a significant pulsation exists at the pre-capillary arterioles with average WSS values more than twice those in the venular side, for the same diameters. WSS heterogeneity is in support of segmental heterogeneity i.e. the endothelial phenotypic and functional difference among arterioles, capillaries and venules. In this review paper, the importance of WSS is described in detail and two more microvascular segments are proposed: a pre-capillary arteriolar and a post-capillary venular segment. The accurate hemodynamic simulation in all microvascular segments seems to be a prerequisite step in the development of dynamic in vitro blood brain barrier (BBB) models and microfluidic platforms on chip. Endothelial cells in the cardiovascular system seem to have sophisticated role acting like cardiovascular processing sensors (CPSs). © 2016 - IOS Press and the authors. Source
