Saffron (Crocus Sativus Linnaeus) is known since ancient times, as wild and as a cultivated plant. Global production is more than 200 tons of saffron per year. The dried stilos of Crocus, known as saffron, are the drug of the plant and are usually strongly colored. It is the most expensive spice in the world because of the demanding collection and drying processes. Many times its cost was competing this of gold. The chemical composition of the stilous of Crocus has been studied extensively. Phytochemical analyzes indicate up to 150 chemicals detectable in dried spots. Modern medicine shows great interest for dried stilous of Crocus Sativus L. During the last decade Crocus Sativus L and its components have been the subject of many ex-perimental studies in biochemical and pharmacological level. The purpose of this study is to make a review of the literature on the newest data about the activity of the extract of Crocus Sativus Linnaeus in Medicine and Aesthetic.

Introduction: Close monitoring of blood glucose levels during the immediate post-acute stroke phase is of great clinical value, as there is evidence that the risk of neurological deterioration is associated with both hyper- and hypoglycaemia. The aim of this review paper is to summarise the evidence on post-stroke blood glucose management and its impact on clinical outcomes, during the early post-acute stage. Findings: Post-stroke hyperglycaemia has been associated with increased cerebral oedema, haemorrhagic transformation, lower likelihood of recanalisation and deteriorating neurological state. Thus, hyperglycaemia during an acute stroke may result in poorer clinical outcomes, infarct progression, poor functional recovery and increased mortality rates. Although hypoglycaemia may also lead to poorer outcomes via further brain injury, it can be readily reversed by glucose administration. In most patients, the goal of regular treatment is euglycaemia and for acute-stroke patients, a reasonable approach is to target control of glucose level at 100–150 mg/dL. Conclusion: Both hypoglycaemia and hyperglycaemia may lead to further brain injury and clinical deterioration; that is the reason these conditions should be avoided after stroke. Yet, when correcting hyperglycaemia, great care should be taken not to switch the patient into hypoglycaemia, and subsequently aggressive insulin administration treatment should be avoided. Early identification and prompt management of hyperglycaemia, especially in acute ischaemic stroke, is recommended. Although the appropriate level of blood glucose during acute stroke is still debated, a reasonable approach is to keep the patient in a mildly hyperglycaemic state, rather than risking hypoglycaemia, using continuous glucose monitoring. © 2016, Italian Society of Endocrinology (SIE).

In this paper, a sensor system architecture for laboratory and in-vivo light scattering studies on blood cells is presented. It aims at correlating Mie scattering to compositional and physiological information of blood cells towards a non-invasive blood-cell counting sensor. An overview of previously reported experimental techniques on light scattering from blood cells is presented. State-of-the-art methods such as differential pulse measurements, vessel pressure optimization identified as promising for enhancing the scattering signal in such measurements. Indicative simulations of Mie scattering by blood cells are presented, illustrating the potential for distinguishing among cells and identifying size distribution. A prototype sensor system based on a 640-660 nm laser light source and a photo diode array is implemented and programmed to obtain mean amplitude and scattering angle measurements. © COPYRIGHT SPIE.

Forest products can be distinguished into wood and non-wood. Non-wood forest products are defined as all the products other than wood derived from forests, shrubs and tree plantations. The main sources of these products are trees, understory plants, mushrooms, and animals. The purpose of the present study was to record the herbaceous and woody taxa of the understory of a deciduous oak forest in Cholomon Chalkidiki, Greece and to classify them into the following categories based on their potential use according to the FAO criteria: (1) Edible; (2) Medicinal and aromatic; (3) Forage; (4) Ornamental, and (5) Dyes. A total of 275 herbaceous and woody taxa were recorded. The majority (76%) of the recorded taxa was classified in one or more of the above categories and their economic value was assessed in terms of their potential uses. Then, the implications of the potential development of commercial activities based on these plants were investigated with a SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis. It is demonstrated that there are opportunities for the sector which would be beneficial for the local population.

OBJECTIVE: To investigate the association between physical activity (PA) and sedentary lifestyle (SL) patterns with overweight (OW), obesity (OB), abdominal obesity (AO) and cardiometabolic comorbidities in Greek adults based on data from the National Epidemiological Survey for the prevalence of obesity. DESIGN: Cross-sectional epidemiological survey. Participants were selected via stratified sampling. 17,887 men and women, 20-70 years old, underwent anthropometric measurements for the estimation of OW, OB and AO prevalence. Assessment of PA, SL patterns and metabolic comorbidities was performed using an in-home questionnaire allowing self-evaluation of diverse activities and self-report for the presence of hypercholesterolemia (HCE), type 2 diabetes mellitus (T2DM) or hypertension (HTN). RESULTS: In men, even small amounts of walking were associated with decreased risk of being OW and AO, while larger amounts were associated with decreased risk of being OB. In women, engagement in entertainment activities for more than 4 hours per week was associated with less risk of being OW. Concerning cardiometabolic comorbidities, substantial improvement was evident mainly for men, e.g. signfiicantly reduced risk for HCE, T2DM and HTN by frequent engagement in exercise. On the other hand, frequent TV watching and long hours of office work significantly increased the risk of HCE and HTN in men. CONCLUSIONS: In Greek adults, and men in particular, walking activity was significantly associated with lower risk for obesity. In addition, frequent exercise and less sedentary behaviour were associated with reduced risk for cardiometabolic factors, mainly hypercholesterolemia and hypertension.

The objective of the study was to identify the potential of Liza haematocheilus to establish self-sustaining populations along the coast of the North Aegean Sea (Greece). The sexual maturity was described histologically from 32 specimens (43-74.4 cm, TL) aged from 3 to 8 years old which were caught between 2003 and 2009 from fishery by-catches. Testicular and ovarian development was synchronous. Males were either maturing (spermatogenesis stage, September to March), mature (spermiating, April to July) or post-mature (recovery stage). Females were in previtellogenesis or maturing (early vitellogenesis, October to January) or mature (late vitellogenesis, July). Mature males (spermatids mean size: 1.5 ± 0.05 μm) were captured from April to July and mature females (late vitellogenic oocytes mean diameter: 499.4 μm) during July, indicating that spermiation and spawning in North Aegean Sea take place from April to July. Contrary to the other grey mullets which overwinter in the sea, the redlip mullet tolerates low water temperatures and migrates to freshwater where competition with other mullets is lacking. The issues of establishing population and evidence for its spawning success still remain open. © 2010 Blackwell Verlag, Berlin.

This paper estimates the benefits and challenges of the Enterprise Resource Planning (ERP) on the Logistics system of an enterprise. By identifying the needs and challenges for the efficient development of an ERP system, the authors understand how an ERP directly contributes to the achievement of operational, strategic, tactical, and organizational benefits. In order to achieve these aims, a research was applied carrying out a closed question survey across Information Technology (IT) practitioners, the majority of who are located in Asia Pacific and Japan, comprising of Enterprise Architects, IT Architects, EAS (Enterprise Application Services) practice leaders, EAS Sales Leaders (Client Principals) all of whom have experience as ERP and logistics practitioners. The findings of the survey show that the biggest challenge concerning the usage of an ERP is not technological, but relates more to issues of trust, collaboration, integration, lack of agility, poor user adoption, implementation timelines, and lack of customer focus. Consequently, understanding how an ERP influences each one of them, will highlight the importance and strategic value of an ERP in terms of the logistics system efficiency.

Background. Obesity is an important public health issue and its prevalence is reaching epidemic proportions in both developed and developing countries. The aim of the present study was to determine associations of overweight (OW), obesity (OB) and abdominal obesity (AO) with marital status and educational level in Greek adults of both genders based on data from the National Epidemiological Survey on the prevalence of obesity. Methods. The selection was conducted by stratified sampling through household family members of Greek children attending school during 2003. A total of 17,341 Greek men and women aged from 20 to 70 years participated in the survey and had anthropometric measurements (height, weight, and waist circumference) for the calculation of prevalence of OW, OB and AO. WHO cut-offs were used to define overweight and obesity categories. Waist circumference of more than 102 cm in men and 88 cm in women defined AO. Marital status and educational level were recorded using a specially designed questionnaire and were classified into 4 categories. Results. The overall prevalence of OB was 22.3% (25.8% in men, 18.4% in women), that of OW 35.2% (41.0% in men, 29.8% in women) and that of AO 26.4% in men and 35.9% in women. Ahigher risk of OB was found in married men (OR: 2.28; 95% CI: 1.85-2.81) and married women (OR: 2.31; 95% CI: 1.73-3.10) than in the respective unmarried ones. Also, a higher risk of AO was found in married men (OR: 3.40; 95% CI: 2.86-4.03) and in married women (OR: 2.40; 95% CI 2.00-2.88) compared to unmarried ones. The risk for being obese was lower among educated women (primary school, OR: 0.76; 95% CI: 0.60-0.96, high school, OR: 0.58; 95% CI: 0.46-0.74 and University, OR: 0.64; 95% CI: 0.49-0.81) than among illiterates. No significant differences were found among men. Conclusions. In Greek adults, marital status was significantly associated with obesity and abdominal obesity status in both genders while educational level was inversely associated with obesity status only in women. © 2010 Tzotzas et al; licensee BioMed Central Ltd.
