AIM: The purpose of this study was the application of a second derivative near infrared spectrophotometric (NIRS) technique to the human calf muscle in order to see if peripheral arterial disease (PAD) patients can be discriminated from control subjects, before, during and after a standard treadmill exercise test. METHODS: Three groups of human subjects were studied: group A consisted of 10 control subjects and groups B and C were formed by PAD patients classified as Fontaine's stage 2a (5 patients) and 2b (10 patients), respectively. The measurement protocol for all groups was 9.75 minutes of standing up (phase 1), 1 minute of exercise (phase 2) and 1 minute of rest (phase 3). Seven variables were defined at different times from the onset of the measurement protocol. RESULTS: All variables were significantly higher (p < 0.05) in group A in comparison to groups B and C. The level of significance was ten times higher (p < 0.005) at the onset (15 seconds) of the experiment and during phases 2 and 3. However, none of the variables in group B was significantly different from those in group C. CONCLUSIONS: It is shown for the first time that a second derivative NIRS technique can discriminate (p = 0.003) healthy subjects from PAD patients, in just 15 seconds of standing, with no exercise requirement. More experiments are required in order to uncover the full potential of the technique in the diagnosis of the PAD. © 2017-IOS Press and the authors. All rights reserved.

Background: Accumulating evidence suggests an association between autism spectrum disorders (ASD) and inflammation in brain regions related to cognitive function. The natural flavonoid luteolin has antioxidant, anti-inflammatory, mast cell-blocking, and neuroprotective effects. It was shown to improve cognitive performance in a mouse model of ASD, but its effect in humans has not been adequately studied. Objectives: The goal of this study was to assess the effectiveness and tolerability in white children with ASD of a dietary supplement containing 2 flavonoids (>95% pure), luteolin (100 mg/capsule, from chamomile) and quercetin (70 mg/capsule), and the quercetin glycoside rutin (30 mg/capsule) from the Sophora japonica leaf, formulated in olive kernel oil to increase oral absorption. Methods: Fifty children (4-10 years old; 42 boys and 8 girls) with ASD were enrolled in a 26-week, prospective, open-label trial at the 2nd University Department of Psychiatry at "Attikon" General Hospital, Athens, Greece. Children were referred for the study by their respective physicians or came from the practice of the senior author. ASD diagnosis by clinical assessment was based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, symptom list and corroborated by using the Autism Diagnostic Observation Schedule. The dose of the study formulation used was 1 capsule per 10 kg weight per day with food. The primary outcome measures were the age-equivalent scores in the Vineland Adaptive Behavior Scales domains. Secondary outcomes included the Aberrant Behavior Checklist, the Autism Treatment Evaluation Checklist, and the Clinical Global Impression-Improvement score. Data were measured at baseline, week 18, and week 26. Parents were interviewed for any possible improvements they noticed and instructed to report any unusual adverse events. Results: A total of 40 children completed the protocol. There was a significant improvement in adaptive functioning as measured by using the VABS age-equivalent scores (8.43 months in the communication domain, 7.17 months in daily living skills, and 8 months in the social domain; P < 0.005), as well as in overall behavior as indicated by the reduction (26.6%-34.8%) in Aberrant Behavior Checklist subscale scores. Age, sex, and history of allergies had no effect on the results, whereas the initial level of functioning or difficulty did predict the final outcome in most of the measures used. There was a transient (1-8 weeks) increased irritability in 27 of the 50 participants. Conclusions: These results are encouraging in that the combination of the flavonoids luteolin and quercetin seemed to be effective in reducing ASD symptoms, with no major adverse effects. identifier: NCT01847521. © 2013 Elsevier HS Journals, Inc.

Introduction: The clinical learning environment constitutes an initial area of professional practice for nurses and student opinion contributes to its improvement. Purpose: The assessment of students' views and perceptions of a Greek nursing school on their clinical learning environment. Material and Methods: The study was concurrent and included 196 students. We used the published questionnaire "Clinical Learning Environment Inventory (CLEI)" which is a tool for identifying and assessing Nursing students' perceptions of the psychosocial characteristics of their clinical learning environment. The questionnaire was anonymous and completed by the students themselves during their clinical training at the hospital. We conducted inductive and descriptive statistics. The level of statistical significance was set at p < 0.05. The statistical program SPSS 16.0 was used. Results: The highest mean score for the Actual Clinical Learning Environment was observed in the scales of "Personalization" (23.97) and "Task orientation" (23.31) while for the Preferred Clinical Learning Environment in the scales of "Personalization" (27.87), "Satisfaction" (26.82) and "Task orientation" (26.78). The lowest mean score for the Actual Clinical Learning Environment was found in the scales of "Innovation" (19.21) and "Individualization" (19.24) while for the Preferred Clinical Learning Environment in the scales of "Individualization" (22.72) and "Involvement" (24.31). Statistically significant positive correlation was found between "Satisfaction" and all other scales of the CLEI. Conclusions: There is a noticeable gap between the expectations and reality of the clinical learning environment for the students in nursing. Reorganization of the educational framework is needed with an emphasis on innovation and individualization. © 2013 Elsevier Ltd.

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.

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.

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.

All theories are based on Axioms which obviously are arbitrary; e.g. SRT, GRT, QM Axioms. Instead of manipulating the experience through a new set of Arbitrary Axioms it would be useful to search, through a basic tool that we have at our disposal i.e. Logic Analysis, for a set of privileged axioms. Physics theories, beyond their particular axioms, can be restated through the basic communication system as consisting of the Classical Logic, the Sufficient Reason Principle and the Anterior-Posterior Axiom. By means of a theorem this system can be proven as contradictory. The persistence in logic is the way for a set of privileged axioms to be found. This can be achieved on the basis of the Claim for Minimum Contradictions. Further axioms beyond the ones of the basic communications imply further contradictions. Thus, minimum contradictions can be achieved when things are described through anterior-posterior terms; due to existing contradictions through stochastic space-time, which is matter itself, described through a Φ wave function and distributed, in a Hypothetical Measuring Field (HMF), through the density probability function P(r, t). On this basis, a space-time QM is obtained and this QM is a unified theory satisfying the requirements of quantum gravity. There are both mass-gravitational space-time (g) regarded as real and charge-electromagnetic (em) space-time that could be regarded as imaginary. In a closed system energy conversion- conservation and momentum action take place through photons, which can be regarded either as (g) or (em) space-time formation whose rest mass is equal to zero. Universe Evolution is described through the interaction of the gravitational (g) with the electromagnetic (em) space-time-matter field and not through any other entities. This methodology implies that there is no need for dark matter. An experiment is proposed relative to the (g)+(em) interaction based on Superconducting Magnetic Field Trapping to validate this approach. © 2010 American Institute of Physics.

Methanol extracts of 4 Salvia species: Salvia officinalis, Salvia sclarea, Salvia tribola and Salvia pomifera, grown in the experimental field of TEI - Larissa, Greece were studied. The leaves mass of the plants was analysed in regard to antiradical activity with DPPH * and ABTS *+ and the ferric reducing antioxidant power using the FRAP reagent. The total content of polyphenols (TP), nonflavonoid (NFP) and flavonoid (FP) phenols as well as that of total flavanols (F-3-ols) was measured. It was found that the DPPH activity in the studied herbs varies from 6.20 to 8.34 umol Trolox/g dry weight (dw), ABTS - from 13.12 to 16.32 μmol Trolox/g dw, and FRAP - from 2.66 to 3.53 umol Trolox/g dw. The content of TP, NTP FP and F-3-ols in the investigated samples depends on the species type and their average content is 11.80, 8.54,3.33 mg GAE/g dw and 95.5 mg CE/g dw. The relation 'dose-effect' between the amount of TP and IC 50 determined by DPPH, ABTS and FRAP is different for the various species. The results are discussed and compared with those reported by other authors.

11 species of medicinal plants including 9 of Apiacea family, 2 of Umbelliferea family and 1 - of Liliacea family were examined for their total contents of polyphenols (TP) and phenol fractions FP, NFP and F-3-ols. The antioxidant activity was estimated by 3 assay methods applying 2 stable free radicals - DPPH• and ABTS•+, and the ferric reducing reagent FRAP. It was established that the leaves of the Lemon thyme L. and Rosmarinus officinalis L. species have the highest levels of TP, 16.85 and 16.84 mg GAE/g dw, respectively. The species under study were characterised by high content of FP and NFP and lower content of F-3-ols, 146 and 111 μg CE/g, respectively. The antioxidant potential corresponds with the TP content and depends on the herb type and the assay method. The values of IC50 of thyme and rozemary, determined with DPPH and ABTS, are the lowest thus indicating the presence of polyphenols with highest activity (1/IC 50). The correlation coefficients (R2) between TP and IC50 measured with DPPH and ABTS amount to 0.9101 and 0.9133, respectively. The results on polyphenols content and antioxidant activity of the separate herbs were discussed and compared with the data reported by other authors.

The khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) is a very destructive pest of stored agricultural products and one of the most important quarantine insect pests worldwide. Very strict legislation and other measures are being taken by many countries so as to prevent the introduction of this pest and avoid export restrictions on their agricultural products. In countries where the khapra beetle is established or occasionally detected, classic management tactics are being improved and new methods are being developed in order to prevent the spread of the infestation or to eradicate, if possible, this feared pest. This review aims not only to provide insight in recent advances on identification, detection, exclusion and control methods of T. granarium, but also to consolidate the available recent and older information and provide an analysis of the published work. Potential areas for growth in the management of khapra beetle include, among others, rapid molecular identification, trapping, combination of fumigation with modified atmospheres or heat, irradiation and plant extracts. Certain advantages, limitations, mode of action, potentiality and effectiveness of each method are discussed. © CAB International 2013.
