Effect of Vitamin E Supplementation on Various Functional Properties of Macrophages and Neutrophils Obtained from Weaned Piglets
No full textSixteen piglets were used to determine the effect of vitamin E supplementation on several functional properties of macrophages and neutrophils obtained from weaned piglets. Piglets, immediately following weaning, were assigned to one of three experimental groups: control (no vitamin E supplementation), low level of vitamin E supplementation (100 mg DL-α-tocopheryl acetate/kg diet) and high level of vitamin E supplementation (300 mg DL-α-tocopheryl acetate/kg diet). Supplementation of vitamin E lasted for a period of 36 days, following a 3-day adaptation period after weaning. Blood samples were collected on days 0, 12, 24 and 36 of the experimental period, monocytes/macrophages and neutrophils were isolated and the following parameters were determined in macrophages and neutrophils activated by phorbol myristate acetate: total cell-associated and membrane-bound urokinase plasminogen activator (u-PA) activity and Superoxide anion production. Results showed that macrophages and neutrophils isolated from piglets that received supplemental vitamin E had higher (P 0.05) on total and membrane-bound u-PA activities and superoxide anion production by porcine macrophages and neutrophils on days 24 and 36 of the experimental period. In conclusion, the low level of vitamin E supplementation is recommended for piglets for the first 2 weeks after weaning

Χειρονομίες και διαφορετικά είδη λόγου σε Έλληνες ομιλητές
No full textΣκοπός της παρούσας έρευνας είναι να διερευνήσει τις ποσοτικές και ποιοτικές διαφορές των χειρονομιών που παράγονται σε διαφορετικά είδη λόγου και την συσχέτισή τους με επιδόσεις σε νευροψυχολογικές δοκιμασίες επιτελικών λειτουργιών. Το ερευνητικό δείγμα που μελετήσαμε απαρτίζεται από 20 υγιείς εθελοντές, οι οποίοι βιντεοσκοπήθηκαν σε τέσσερα διαφορετικά είδη λόγου και υποβλήθηκαν σε αξιολόγηση των επιτελικών λειτουργιών με τέσσερις νευροψυχολογικές δοκιμασίες, Βάση της θεωρίας του McNeil (1992) ορίστηκαν δυο βασικές κατηγορίες χειρονομιών, οι αναφορικές και οι μη αναφορικές. Η πρώτη κατηγορία αποτελείται από τους υπότυπους των εικονικών, μεταφορικών και δεικτικών χειρονομιών και η δεύτερη, από τις ρυθμικές και τις μη ρυθμικές. Από την ανάλυση ων δεδομένων προέκυψαν διαφορές μέσων τιμών των διαφορετικών κατηγοριών των χειρονομιών τόσο ανεξάρτητα, όσο και σε αλληλεπίδραση με τα διαφορετικά είδη λόγου. Οι μη αναφορικού τύπου χειρονομίες επικρατούν γενικά και είναι περισσότερες στο παραμύθι της κοκκινοσκουφίτσας και στην ιστορία της γέννησης του Χριστού. Ο υπότυπος των χειρονομιών φάνηκε να έχει κύρια επίδραση στο συνολικό αριθμό των χειρονομιών με τις μη αναφορικές μη ρυθμικού τύπου, να υπερέχουν σε σύγκριση με τις μεταφορικές, εικονικές και δεικτικές, τις ρυθμικές να υπερέχουν έναντι των δεικτικών και εικονικών και τις μεταφορικές να είναι περισσότερες από τις δεικτικές και εικονικές. Επίσης, οι εικονικές ήταν περισσότερες από τις δεικτικές. Το είδος του λόγου δεν φαίνεται να επηρεάζει τον αριθμό των χειρονομιών. Ο συνολικός αριθμός χειρονομιών, οι εικονικές και οι μεταφορικές χειρονομίες στο παραμύθι της κοκκινοσκουφίτσας και οι μη αναφορικές, ρυθμικού και μη ρυθμικού τύπου στην περιγραφή της εικόνας του cookie theft συσχετίζονται αρνητικά με το TMT-A γεγονός που υποδεικνύει θετική συσχέτιση των χειρονομιών με την ταχύτητα επεξεργασίας, την οπτική προσοχή και τον κινητικό συντονισμό.The purpose of this research is to investigate the quantitative and qualitative differences in gestures produced in different types of speech and their correlation with performance on neuropsychological tests of executive functions. The research sample consists of 20 healthy volunteers who were videotaped in four different types of speech and assessed for executive functions using four neuropsychological tests. Based on McNeil's (1992) theory, two main categories of gestures were defined: referential and non-referential. The first category consists of the subtypes of iconic, metaphoric, and deictic gestures, while the second includes rhythmic and non-rhythmic gestures. Data analysis revealed differences in the mean values of the different categories of gestures, both independently and in interaction with the different types of speech. Non-referential gestures generally prevailed and were more numerous in the story of Little Red Riding Hood and the story of the birth of Christ. The subtype of gestures was found to have a major effect on the total number of gestures, with non-referential, non-rhythmic gestures outnumbering metaphoric, iconic, and deictic gestures; rhythmic gestures outnumbering deictic and iconic gestures; and metaphoric gestures outnumbering deictic and iconic gestures. Iconic gestures were also more numerous than deictic ones. The type of speech did not seem to affect the number of gestures. The total number of gestures, iconic and metaphoric gestures in the story of Little Red Riding Hood, and non-referential, rhythmic and non-rhythmic gestures in the description of the cookie theft picture negatively correlated with TMT-A, indicating a positive correlation of gestures with processing speed, visual attention, and motor coordination
Optimization of cannula visibility during ultrasound-guided subclavian vein catheterization, via a longitudinal approach, by implementing echogenic technology
No full textObjective. One limitation of ultrasound-guided vascular access is the technical challenge of visualizing the cannula during insertion into the vessel. We hypothesized that the use of an echogenic vascular cannula (EC) would improve visualization when compared with a nonechogenic vascular cannula (NEC) during real-time ultrasound-guided subclavian vein (SCV) cannulation in the ICU. Material and Methods. Eighty mechanically ventilated patients were prospectively enrolled in a randomized study that was conducted in a medical-surgical ICU. Forty patients underwent EC and 40 patients were randomized to NEC. The procedure was ultrasound-guided SCV cannulation via the infraclavicular approach on the longitudinal axis. Results. The EC group exhibited increased cannula visibility as compared to the NEC group (92 % ± 3 % versus 85 ± 7 %, resp., P < 0.01). There was strong agreement between the procedure operators and independent observers (k = 0.9, 95 confidence intervals assessed by bootstrap analysis = 0.87 to 0.93; P < 0.01). Access time (12.1 s ± 6.5 versus 18.9 s ± 10.9) and the perceived technical difficulty of the ultrasound method (4.5 ± 1.5 versus 7.5 ± 1.5) were both decreased in the EC group compared to the NEC group (P < 0.05). Conclusions. Echogenic technology significantly improved cannula visibility and decreased access time and technical complexity optimizing thus real-time ultrasound-guided SCV cannulation via a longitudinal approach. © 2012 Konstantinos Stefanidis et al

No full text@HOME is a new Eu-Project in Tele Home care
No full textS.970-972@Home is a robust platform for real-time remote monitoring of patients at their home by doctors at the hospital. Health monitoring sensors, which have the capability to measure quick and easy vital parameters such as blood pressure, pulse rate, temperature, oxygen saturation (SpO2), as well as ECG 12 leads are used. Additionally, an advantage of the platform is that all the sensors are wearable and the patient is able to walk around indoors or outdoors. Moreover, the sensors are able to convey the recorded data over Bluetooth, a short-range wireless communication, to any Bluetooth enabled device such as Desktop computer or a Pocket PC.47Supplement 1, Part
