Ethics is a philosophical branch of inquiry that reasons between what is right and wrong. The moral philosophy of Socrates, Aristotle, and Plato from ancient Greek became the basis of most of the western ethics. These days, ethics can be divided based on its inquiries for example, normative, descriptive, metaethics, and applied ethics or based on its theories like utilitarianism, emotivism, and universal ethics. In context with applied ethics that examines issues involving emerging technologies, this study will look into the ethics of Malaysian stem cell technology based on written literature. It was mainly to identify Malaysian literature on stem cell ethics through conventional search since the mainstream international database indicated an obvious shortage. The critical review of this literature will facilitate in the understanding of unique position of Malaysia towards stem cell and its ethics in reference to the limited number. Despite the limitation, this can be a preliminary study urging for more inquiries and exploration to fulfil the multiple perspectives in ethics such as the diversity of Malaysian ethics, the impact of ethics in stem cell regulation in Malaysia, and if western contemporary ethics influences Malaysian ethics particularly involving stem cell technology.
Attitudes towards assisted death activities among medical students, the future health gatekeepers, are scarce and controversial. The aims of this study were to explore attitudes on euthanasia and physician-assisted suicide among final year medical students in Athens, to investigate potential differences in attitudes between male and female medical students and to review worldwide attitudes of medical students regarding assisted death activities. A 20- item questionnaire was used. The total number of participants was 251 (mean age 24.7±1.8 years). 52.0% and 69.7% of the respondents were for the acceptance of euthanasia and physician-assisted suicide, respectively. Women's attitudes were more often influenced by religious convictions as well as by the fact that there is a risk that physician-assisted suicide might be misused with certain disadvantaged groups. On the other hand, men more often believed that a request for physician-assisted suicide from a terminally ill patient is prima-facie evidence of a mental disorder, usually depression. Concerning attitudes towards euthanasia among medical students in various countries there are contradictory results. In USA, the Netherlands, Hungary and Switzerland most of the students supported euthanasia and physician-assisted suicide. However, in many other countries such as Norway, Sweden, Yugoslavia, Italy, Germany, Sudan, Malaysia and Puerto Rico most students expressed negative positions regarding euthanasia and physician assisted suicide.
In this article, we speculate the reasons behind the death of Achilles during the Trojan war. Roots of Medicine can be traced to ancient Greek history. From the Hippocrates Oath to the Achilles tendon, it all has a long story to tell. In the history of ancient Greece, Gods played an important role in their lives and the immortals existed.
Ayurveda is one of the traditional medicinal systems of Indian. The philosophy behind Ayurveda is preventing unnecessary suffering and living a long healthy life. Ayurveda involves the use of natural elements to eliminate the root cause of the disease by restoring balance, at the same time create a healthy life-style to prevent the recurrence of imbalance. Herbal medicines have existed world-wide with long recorded history and they were used in ancient Chinese, Greek, Egyptian and Indian medicine for various therapies purposes. World Health Organization estimated that 80% of the word's inhabitants still rely mainly on traditional medicines for their health care. The subcontinent of India is well-known to be one of the major biodiversity centers with about 45,000 plant species. In India, about 15,000 medicinal plants have been recorded, in which the communities used 7,000-7,500 plants for curing different diseases. In Ayurveda, single or multiple herbs (polyherbal) are used for the treatment. The Ayurvedic literature Sarangdhar Samhita' highlighted the concept of polyherbalism to achieve greater therapeutic efficacy. The active phytochemical constituents of individual plants are insufficient to achieve the desirable therapeutic effects. When combining the multiple herbs in a particular ratio, it will give a better therapeutic effect and reduce the toxicity. This review mainly focuses on important of the polyherbalism and its clinical significance.
For many decades it has been accepted that marine turtle hatchlings from the same nest generally emerge from the sand together. However, for loggerhead turtles (Caretta caretta) nesting on the Greek Island of Kefalonia, a more asynchronous pattern of emergence has been documented. By placing temperature loggers at the top and bottom of nests laid on Kefalonia during 1998, we examined whether this asynchronous emergence was related to the thermal conditions within nests. Pronounced thermal variation existed not only between, but also within, individual nests. These within-nest temperature differences were related to the patterns of hatchling emergence, with hatchlings from nests displaying large thermal ranges emerging over a longer time-scale than those characterised by more uniform temperatures. In many egg-laying animals, parental care of the offspring may continue while the eggs are incubating and also after they have hatched. Consequently, the importance of the nest site for determining incubation conditions may be reduced since the parents themselves may alter the local environment. By contrast, in marine turtles, parental care ceases once the eggs have been laid and the nest site covered. The positioning of the nest site, in both space and time, may therefore have profound effects for marine turtles by affecting, for example, the survival of the eggs and hatchlings as well as their sex (Janzen and Paukstis 1991). During incubation, sea turtle embryos grow from a few cells at oviposition to a self-sufficient organism at hatching some 50-80 days later (Ackerman 1997). After hatching, the young turtles dig up through the sand and emerge typically en masse at the surface 1-7 nights later, with a number of stragglers following over the next few nights (Christens 1990). This contrasts with the frequently observed pattern of hatching asynchrony in birds. It has been suggested that the cause of mass emergence in turtles is that eggs within a clutch are fertilised within a short period of time and then, when thermal conditions within the nest are uniform, develop at very similar rates and hence hatch and emerge together (Porter 1972). As a corollary of this idea, it would be predicted that when there are pronounced within-nest thermal gradients, development rates of siblings will be different and hence asynchronous hatching and emergence might occur. While it may be energetically beneficial for hatchlings to emerge in a group (Carr and Hirth 1961), if the extent of hatching asynchrony is marked then there may be severe costs for individuals if they wait for all their siblings to hatch before attempting to dig out of the sand (Hays and Speakman 1992). Under such conditions, the protracted emergence of small groups of hatchlings over several nights may be favoured. Examination of the literature suggests that emergence asynchrony may be more widespread than generally considered. For example, Witherington et al. (1990) described loggerhead turtle hatchlings (Caretta caretta) emerging over 4 days in Florida; for green turtles (Chelonia mydas), Hendrickson (1958) documented that nests in Malaysia and Sarawak produced hatchlings for up to 8 days; whilst Diamond (1976) found that hawksbill (Eretmochelys imbricata) nests on Cousin Island, Seychelles, were active for up to 4 days. Similarly, on the Greek Island of Kefalonia, we have shown that emergence from individual loggerhead turtle nests may occur on up to 11 nights (Hays and Speakman 1992). It is logical to suppose that asynchronous emergence relates to thermal gradients within nests, since the incubation duration of sea turtle eggs is related to temperature, with eggs hatching quicker when the temperature is higher. Here we test this hypothesis by measuring thermal variations within loggerhead turtle nests and comparing these variations to the patterns of hatchling emergence.
An Electronic Medical Record (EMR) is a patient's database record that can be transmitted securely. There are a diversity of EMR systems for different medical units to choose from. The structure and value of these systems is the focus of this qualitative study, from a medical professional's standpoint, as well as its economic value and whether it should be shared between health organizations. The study took place in the natural setting of the medical units' environments. A purposive sample of 40 professionals in Greece and Oman, was interviewed. The study suggests that: (1) The demographics of the EMR should be divided in categories, not all of them accessible and/or visible by all; (2) The EMR system should follow an open architecture so that more categories and subcategories can be added as needed and following a possible business plan (ERD is suggested); (3) The EMR should be implemented gradually bearing in mind both medical and financial concerns; (4) Sharing should be a patient's decision as the owner of the record. Reaching a certain level of maturity of its implementation and utilization, it is useful to seek the professionals' assessment on the structure and value of such a system.
Preparation of natural hazards maps are vital and essential for urban development. The main scope of this study is to synthesize natural hazard maps in a single multi-hazard map and thus to identify suitable areas for the urban development. The study area is the drainage basin of Xerias stream (Northeastern Peloponnesus, Greece) that has frequently suffered damages from landslides, floods and earthquakes. Landslide, flood and seismic hazard assessment maps were separately generated and further combined by applying the Analytical Hierarchy Process (AHP) and utilizing a Geographical Information System (GIS) to produce a multi-hazard map. This map represents the potential suitability map for urban development in the study area and was evaluated by means of uncertainty analysis. The outcome revealed that the most suitable areas are distributed in the southern part of the study area, where the landslide, flood and seismic hazards are at low and very low level. The uncertainty analysis shows small differences on the spatial distribution of the suitability zones. The produced suitability map for urban development proves a satisfactory agreement between the suitability zones and the landslide and flood phenomena that have affected the study area. Finally, 40% of the existing urban pattern boundaries and 60% of the current road network are located within the limits of low and very low suitability zones.
The Functionality Appreciation Scale is a widely used instrument for the measurement of an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). In the present study, we examined the psychometric properties of a novel Greek translation of the FAS in Cypriot adults. A total of 448 women and 345 men from the Republic of Cyprus completed the FAS, as well as validated measures of body appreciation, appearance evaluation, and symptoms of disordered eating, and self-esteem. Exploratory and confirmatory factor analyses supported a unidimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, with the gender difference in FAS scores not reaching significance. FAS scores were also found to have adequate composite reliability and convergent (significant associations with body appreciation, appearance evaluation, and symptoms of disordered eating) and concurrent validity (significant associations with self-esteem). Finally, functionality appreciation predicted self-esteem once the effects of all other variables had been accounted for, supporting incremental validity. Overall, these results suggest that the Greek FAS is a psychometrically valid tool for the assessment of functionality appreciation in adults from Cyprus.
Saffron, Crocus sativus (Iridaceae), is a perennial herb, which earned its popularity as both medicine and spice. It is an inhabitant of different mountainous regions of Asia Minor to Greece, Western Asia, Egypt, and India. The benefits of saffron as an antidepressant are well-documented. Almost 150 volatile and nonvolatile compounds are obtained from the chemical analysis of this plant. Fewer than 50 constituents elucidated and identified so far showed phytochemical characteristics. The major bioactive compounds identified are safranal, crocin, and picrocrocin, which are responsible for its aroma as well as its bitter taste. This review is an attempt to encompass the methods of analysis and pharmacodynamic and pharmacokinetic properties of saffron followed by its efficacious and safe potential.
The Greek letter φ (Phi) represents one of the most mysterious numbers (1.618…) known to humankind. Historical approbation for φhas led to the monikers “The Golden Number” or “The Divine Proportion”. This simple, but inscrutable number, is inseparably linked to the recursive mathematical sequence which produces Fibonacci numbers. The study of the Fibonacci sequence exists in most aspects of life starting from the leaves of a non-flowering plant, design, paintings, animals, and even human body. Despite its wide-spread prevalence and existence, the Fibonacci series and also the Rule of Golden Proportions have not been widely documented within the human body. The main objective of this study is to prove that the length of the human hand bone is in step with the Fibonacci series to spot the degree of movement and variation for every finger. Victimization of the sample z test with 95% confidence interval, this analysis shows that just one of the four bone length ratios contained the ratio phi φ within the 95% confidence interval and follow the Fibonacci series, that of the little finger metacarpal and proximal phalanx in both hands. The largest variability was seen within the little finger phalangeal relationships and other fingers will follow mathematical relative series. Due to the relationship with the golden number, it will facilitate in monitoring the individual with an injured hand, especially if injured in small fingers throughout a medical aid, or to identify the cause of the problem of physical functioning of the hands or individual fingers. Hence, it should be helpful for the length of the clenched fist to perform in reconstruction or placement of the prosthesis.
This study investigates how field practices in handling and applying pesticides influence the long-term patterns of professional agricultural operators' exposure to pesticides. It presents the first use of a comprehensive pesticide application dataset collected on behalf of the European Food Safety Authority with 50 operators selected to cover arable and orchard cropping systems in Greece, Lithuania and the UK. Exposure was predicted based on the harmonised Agricultural Operator Exposure Model (AOEM) and compared with Acceptable Operator Exposure Levels (AOELs). The amount of pesticides handled by individual operators across a cropping season was largest in the UK arable and orchard systems (median 580 and 437kg active substance, respectively), intermediate for the arable systems in Greece and Lithuania (151 and 77kg, respectively), and smallest in the Greek orchard system (22kg). Overall, 30 of the 50 operators made at least one application within a day with predicted exposure greater than the AOEL. The rate of AOEL exceedance was greatest in the Greek cropping systems (8 orchard operators, 2.8-16% of total applications; 7 arable operators, 1.1-14% of total applications), and least for the Lithuanian arable system (2 operators, 2.9-4.5% of total applications). Instances in Greece when predicted exposure exceed the AOEL were strongly influenced by the widespread use of wettable powder formulations (>40% of the total pesticide active substance handled for 11 of the 20 Greek operators). In contrast, the total area of land treated with an active substance on a single day was more important in the UK and Lithuania (95th percentile observed value was 132 and 19haday-1 for UK arable and orchard systems, respectively). Study findings can be used to evaluate current assumptions in regulatory exposure calculations and to identify situations with potential risk that require further analysis including measurements of exposure to validate model estimations.
The construct of intuitive eating is commonly assessed using the 23-item, 4-factor Intuitive Eating Scale-2 (IES-2; Tylka & Kroon Van Diest, 2013). In this study, we assessed the psychometric properties of a novel Greek translation of the IES-2 in adults from Cyprus. In Study 1 (N = 626), an exploratory factor analysis indicated that the IES-2 should be conceptualized as consisting of six factors that showed complete invariance across women and men. Study 2 (N = 793), using exploratory structural equation modelling (ESEM) and beifactor analysis (B-ESEM), indicated that the 6-factor B-ESEM model had adequate fit and evidenced complete invariance across sex once the correlated uniqueness of negatively worded IES-2 items was accounted for. This final model evidenced adequate composite reliability, and a global G-factor evidenced adequate convergent, concurrent, and discriminant validity. In contrast, the IES-2 S-factors showed more equivocal patterns of validity, with some S-factors showing less-than-adequate associations with body image variables, self-esteem, symptoms of disordered eating, and fruit and vegetable intake. In general, these results provide satisfactory evidence of the psychometric properties of the Greek IES-2 in adults from Cyprus, but also suggest that models of IES-2 scores may vary across national or cultural contexts.
Occupational exposure to pesticide mixtures comprising active substance(s) and/or co-formulant(s) with known/possible endocrine-disrupting activity was assessed using long-term activity records for 50 professional operators representing arable and orchard cropping systems in Greece, Lithuania, and the UK. Exposure was estimated using the harmonised Agricultural Operator Exposure Model, and risk was quantified as a point of departure index (PODI) using the lowest no observed (adverse) effect level. Use of substances with known/possible endocrine activity was common, with 43 of the 50 operators applying at least one such active substance on more than 50% of spray days; at maximum, one UK operator sprayed five such active substances and 10 such co-formulants in a single day. At 95th percentile, total exposure was largest in the UK orchard system (0.041 × 10-2 mg kg bw-1 day-1) whereas risk was largest in the Greek cropping systems (PODI 0.053 × 10-1). All five cropping systems had instances indicating potential for risk when expressed at a daily resolution (maximum PODI 1.2-10.7). Toxicological data are sparse for co-formulants, so combined risk from complex mixtures of active substances and co-formulants may be larger in reality.
The Teruel Orthorexia Scale (TOS) is a 17-item instrument designed to assess distinct facets of Orthorexia Nervosa (ON) and Healthy Orthorexia (HO). While a bidimensional model of TOS scores has been supported in diverse national and linguistic groups, the psychometric properties of the TOS have not been previously assessed in Greek-speaking populations. To rectify this, we assessed the psychometric properties of a novel Greek translation of the TOS in a sample of adults from Cyprus. A total of 1248 respondents (710 women, 538 men) completed the Greek TOS, as well as previously validated measures of perfectionism, obsessive-compulsive symptomatology, eating restriction, negative affect, and appearance evaluation. Our results showed that a bidimensional model of the TOS had less-than-adequate fit when modelled using both confirmatory factor analysis and exploratory structural equation modeling (ESEM). Conversely, both exploratory factor analysis and ESEM supported extraction of a 3-factor model consisting of a HO facet and separate components of emotional orthorexia and cognitive-social orthorexia. This 3-factor model showed a lack of measurement bias (measurement invariance across gender identity and lack of differential item functioning as function of age and body mass index), but there were differences in latent factor means as function of respondent age and body mass index. The 3-factor model showed adequate evidence of construct validity, with the latent emotional orthorexia and cognitive-social orthorexia facets showing significant and moderate associations with the additional constructs measured in the survey. Broadly speaking, these findings support the psychometric properties of a 3-factor model of the Greek TOS, but also suggest that the bidimensional model of the TOS may not have universal applicability. We encourage further assessments of factorial validity in other national and linguistic contexts.
Certain uncommon genetic disorders occur relatively frequently in the various population groups of Southern Africa. Prominent among these are porphyria, colonic polyposis and sclerosteosis in the Afrikaner community, Huntington's chorea in the British, Gaucher's and Tay-Sachs diseases in the Jewish population, glucose-6-phosphate dehydrogenase deficiency (G-6-PD deficiency) and thalassaemia in the Greek community, various skeletal dysplasias in the Black group, lipoid proteinosis and cleidocranial dysostosis in the Cape Coloured population, diabetes mellitus in the Indian community and retinitis pigmentosa in the Tristan da Cunha islanders. In addition, 'private' syndromes have been encountered in virtually every group. Awareness of the ethnic distribution of unusual genetic conditions is of considerable practical importance during the differential diagnosis of obscure disease.
OBJECTIVE: This study aimed to identify cultural-level variables that may influence the extent to which adolescents from different cultural groups are dissatisfied with their bodies.
DESIGN: A sample of 1730 male and 2000 female adolescents from Australia, Fiji, Malaysia, Tonga, Tongans in New Zealand, China, Chile, and Greece completed measures of body satisfaction, and the sociocultural influences on body image and body change questionnaire, and self-reported height and weight. Country gross domestic product and national obesity were recorded using global databases.
RESULTS: Prevalence of obesity/overweight and cultural endorsement of appearance standards explained variance in individual-level body dissatisfaction (BD) scores, even after controlling for the influence of individual differences in body mass index and internalization of appearance standards.
CONCLUSIONS: Cultural-level variables may account for the development of adolescent BD.
KEYWORDS: GDP; adolescents; body dissatisfaction; culture; sociocultural influences
INTRODUCTION: Increases in electronic cigarette (e-cigarette) awareness and current use have been documented in high income countries but less is known about middle and low income countries.
METHODS: Nationally representative household survey data from the first four Global Adult Tobacco Surveys to assess e-cigarettes were analyzed, including Indonesia (2011), Malaysia (2011), Qatar (2013), and Greece (2013). Correlates of e-cigarette awareness and current use were calculated. Sample sizes for Greece and Qatar allowed for further analysis of e-cigarette users.
RESULTS: Awareness of e-cigarettes was 10.9% in Indonesia, 21.0% in Malaysia, 49.0% in Qatar, and 88.5% in Greece. In all four countries, awareness was higher among male, younger, more educated, and wealthier respondents. Current e-cigarette use among those aware of e-cigarettes was 3.9% in Malaysia, 2.5% in Indonesia, 2.2% in Greece and 1.8% in Qatar. Across these four countries, an estimated 818 500 people are currently using e-cigarettes. Among current e-cigarette users, 64.4% in Greece and 84.1% in Qatar also smoked cigarettes, and, 10.6% in Greece and 6.0% in Qatar were never-smokers.
CONCLUSIONS: E-cigarette awareness and use was evident in all four countries. Ongoing surveillance and monitoring of awareness and use of e-cigarettes in these and other countries could help inform tobacco control policies and public health interventions. Future surveillance should monitor use of e-cigarettes among current smokers and uptake among never-smokers and relapsing former smokers.
