Abstract: Roads, despite playing a key role in economy, begin or aggravate processes of forest fragmentation and lead to several species losing their natural habitats, acting as filters and barriers that impose challenges to animal locomotion. Wildlife crossings seek to reestablish the connectivity of the landscape. In general, after being installed, these passages need to be evaluated regarding their functioning. In this study, we present the results of monitoring the underpasses on Serra da Macaca Park Road (SP-139), which crosses Carlos Botelho State Park. The underpasses, constituted by bridges and culverts, were constructed after a license obtained to restore this section of the road. Camera traps were installed inside all crossing structures, and systematic samples were obtained through four field expeditions, with sampling efforts of 10 days each, between March 2018 and February 2019. The footprints found around the intersection structures were also considered. A two-sided Student’s t-test was applied to verify differences in richness between the underpasses that have distinct types of margins. Differences in abundance were analyzed through the non-parametric Mann-Whitney test. A Whittaker diagram was generated according to the order of the species, from the most common to the rarest, while their diversity was estimated through Simpson’s Diversity Index (1 - D). The Pearson correlation coefficient was used to study the interaction between diversity and altitude variation. We observed a richness of 16 species of terrestrial tetrapods, without any statistically significant differences between underpasses with dry or flooded margins. Cuniculus paca was the most abundant species, and higher altitudes presented the most diversity. We concluded that the underpasses located inside Permanent Preservation Areas (PPAs) of watercourses are essential to maintain the flow of animals beneath the road.

Background/Aims: Peritoneal protein loss (PPL) is associated with cardiovascular disease and mortality in peritoneal dialysis (PD). Controversial results have been published about the effect of paricalcitol in PPL among PD patients. This study intends to analyze the relationship between paricalcitol and PPL in PD. Methods: In a retrospective study, prevalent PD patients were divided into 2 groups: “with paricalcitol” and “without paricalcitol”. X2-test, Student’s t test, Pearson correlation coefficient and Logistic Regression analysis were applied. Results: Eighty-two patients were included. PPL was lower among patients medicated with paricalcitol (5.17 ± 1.71 vs. 6.79 ± 2.10 g/24 h, p = 0.0001). In multivariate analysis, paricalcitol and dialysate/plasma ratio of creatinine (D/P creatinine) were independently related to PPL (OR 4.270 [1.437–12.684], p = 0.009 and OR 0.205 [0.064–0.659], p = 0.008, respectively), adjusted for diabetes. Conclusion: Paricalcitol and D/P creatinine were independently related to PPL. Paricalcitol may have an effect on PPL in PD patients

Sediments of the Bonny Estuary, which is repository to pollutants from various industrial and shipment activities in its catchment was investigated for rate of natural attenuation of toxic metals (Cd, Mn, Cr, Pb, Cu, Ni, Fe) under aerobic and anaerobic conditions. Samples were collected with pre-grab sampler from seabed, sieved in the laboratory and monitored under aerobic and anaerobic conditions. After incubation at 18°C, harvests were made on days 1, 14, 28 and 42 and levels of the metals determined spectrophotometrically. Variation plots, ANOVA, Means plots, Student’s t-test and Pearson correlation (r) were used to analyze data. Concentration reductions were higher in aerobic condition in the order Cu(15.5%)> Cd(11.4%)> Fe(8.0%)>Mn(5.7%)> Cr(4.4%)> Ni(4.2%)>Pb(3.9%) than in anaerobic condition which was in the order Cu(7.5%)> Cd(7.4%)>Pb(2.4%)>Mn/Cr(1.8% each)> Fe(0.9%)> Ni(0.5%). There was significant heterogeneity in metals reductions (Sig. F=0.000) on all the harvest days, especially of Cu, Pb and Fe at P<0.05. Attenuation of Mn also differed markedly between the aerobic and anaerobic conditions (Sig. t=0.005) at the 95% confidence interval. pH influenced the attenuation of Ni (r=0.766) and Fe (r=0.795) (P<0.05) as well as Cd (r=0.968), Cr (r=0.861), Pb (r=0.989) and Cu (r=0.950) (P<0.01). Results indicate that rate of attenuation was slow and slightly enhanced by oxygenation.

ABSTRACT Changes in extreme precipitation have been observed in regions where frequent rainfalls occur over short periods of time followed by prolonged droughts, creating, as a result, new watershed scenarios. Recent studies have attributed such occurrences to possible climate changes. This paper analyzes the correlation between extreme events recorded in the Sub-basin 39, located in Northeastern Brazil, and the anomalies caused by sea surface temperature - SST and the atmospheric systems operating in the region. Pearson correlation coefficients have been used combined with the variables analyzed. For such, trends in precipitation have been obtained by using the method of least squares together with linear regression and the Student's t test. The results obtained have demonstrated that due to the geographical position of the region investigated, both maximum extreme events (areas with positive trends) and minimum extreme events (areas with negative trends) are more dependent on the Dipole Atlantic than on the effects of El Niño Southern Oscillation - ENOS.

Σκοπός της μελέτης. Η αξιολόγηση της άρδευσης των ιστών και η κλινική σημασία της συγκέντρωσης των γαλακτικών, καθώς και η εκτίμηση της νεφρικής λειτουργίας, με τον έλεγχο της κρεατινίνης του ορού και της κάθαρσης της κρεατινίνης, κατά την ενδαγγειακή αποκατάσταση ανευρυσμάτων κοιλιακής (EVAR: Endovascular Aortic Repair) και θωρακικής αορτής (TEVAR: Thoracic Endovascular Aortic Repair) Οι μεταβλητές αυτές συσχετίζονται με τη χειρουργική τεχνική, την αναισθητική τεχνική και την έκβαση των ασθενών με την εμφάνιση επιπλοκών. Υλικό και μέθοδοι. Στην παρούσα μελέτη περιλήφθησαν 226 ασθενείς με την προεγχειρητική ένδειξη για ενδαγγειακή αποκατάσταση είτε κοιλιακής αορτής είτε θωρακικής αορτής. Η επέμβαση ολοκληρώθηκε ως ενδαγγειακή αποκατάσταση ανευρύσματος κοιλιακής αορτής σε 170 ασθενείς (11 γυναίκες ασθενείς) και σε 9 από τους 170 με την ένδειξη της επείγουσας αντιμετώπισης ρήξης ανευρύσματος κοιλιακής αορτής. Ως ενδαγγειακή αποκατάσταση ανευρύσματος θωρακικής αορτής η επέμβαση ολοκληρώθηκε σε 41 ασθενείς (5 γυναίκες) και σε 5 από τους 41 με την ένδειξη της επείγουσας αντιμετώπισης ρήξης ανευρύσματος θωρακικής αορτής. Σύμφωνα με το πρωτόκολλο έρευνας, η μέτρηση γαλακτικών γίνεται σε 4 συγκεκριμένες χρονικές στιγμές: Η πρώτη πραγματοποιείται μετά την εισαγωγή στη γενική αναισθησία (θωρακική ενδαγγειακή αποκατάσταση) ή την εφαρμογή της περιοχικής αναισθησίας (κυριότερη αναισθητική επιλογή στην ενδαγγειακή αποκατάσταση κοιλιακής αορτής) και αποτελεί και το δείγμα αναφοράς. Η δεύτερη μετά την έκπτυξη του μοσχεύματος στο κεντρική ζώνη στήριξης. Η τρίτη μέτρηση μετά την έκπτυξη του μοσχεύματος περιφερικά (διχαλωτή πρόθεση ή μονού αυλού μόσχευμα). Τέλος η τέταρτη μέτρηση συνδέεται με το τέλος της επέμβασης. Η επόμενη μέτρηση είναι άμεσα μετεγχειρητική είτε στη Μονάδα Εντατικής Θεραπείας (Μ.Ε.Θ.) είτε στη Μονάδα Μεταναισθητικής Φροντίδας (Μ.Α.Α.Φ.). Για τον έλεγχο της νεφρικής λειτουργίας χρησιμοποιήθηκαν η παράμετρος της κρεατινίνης και της κάθαρσης της κρεατινίνης σε δύο διαφορετικές χρονικές στιγμές: Η προεγχειρητική και η τιμή της πρώτης μετεγχειρητικής μέρας. Αντίστοιχα η κάθαρση της κρεατινίνης, ως δείκτης ρυθμού σπειραματικής διήθησης (GFR – glomerular filtration rate), υπολογίζεται σύμφωνα με τον τύπο Cockroft – Gault: Κάθαρση κρεατινίνης (ml/min) = [(140 – ηλικία/έτη) Χ (βάρος σώματος/Kg)] / [ 72 Χ κρεατινίνη ορού (mg/dl) X (0,85 για γυναίκες). Για τη βιοστατιστική ανάλυση των στοιχείων χρησιμοποιήθηκαν τα προγράμματα στατιστικής ανάλυσης και επεξεργασίας δεδομένων (statistical package) SPSS 16.0 edition (SPSS for Windows) και Primer Biostatistics 4.0 for Windows. Η στατιστική ανάλυση των μη παραμετρικών δεδομένων πραγματοποιήθηκε με την κατά Friedman ανάλυση διακύμανσης σε συνδυασμό με τις δοκιμασίες signed rank Wilcoxon, Kruskal Wallis και Mann Whitney U. Για τα παραμετρικά δεδομένα χρησιμοποιήθηκαν οι δοκιμασίες Student’s t-test for paired samples και Analysis for Variance (ANOVA). Η δοκιμασία συσχετίσεων έγινε με τη δοκιμασία Pearson Correlation. Τα αποτελέσματα εκφράζονται ως Μέσος όρος ± Τυπικό Σφάλμα. Η στατιστική σημαντικότητα ορίστηκε ως *p<0.05, **p<0.01, ***p<0.001. Αποτελέσματα. Συγκρίνοντας δημογραφικά στοιχεία και προεγχειρητικό εργαστηριακό έλεγχο των ασθενών, βλέπουμε ότι δεν υπάρχει στατιστικά σημαντική διαφορά ανάμεσα στις δύο ομάδες της ενδαγγειακής αποκατάστασης (κοιλιακής και θωρακικής αορτής). Δεν υπάρχει καμιά συσχέτιση ανάμεσα στις εξεταζόμενες μεταβλητές της νεφρικής λειτουργίας και την εμφάνιση επιπλοκών (όπου επιπλοκές = διεγχειρητικές απώλειες αίματος, συνοδός χορήγηση παραγώγων αίματος, ενδεχόμενη ισχαιμία του σκέλους ή επανεγχείρηση του ασθενούς). Υπάρχει στατιστικά σημαντική διαφορά ανάμεσα στα διαφορετικά είδη αναισθησίας και την παραγωγή ούρων. Συγκριτικά έχουμε: Ραχιαία αναισθησία – 669,43 ± 37,51 ml ούρων, Γενική αναισθησία – 933,26 ± 86,69, p,0.003. Σύμφωνα με τη σύγκριση των δύο διαφορετικών ομάδων (ομάδα κρεατινίνης < 1,3 mg/dl έναντι ομάδας κρεατινίνης >1,3 mg/dl), ενώ δεν υπάρχει στατιστικά σημαντική διαφορά ως προς την τιμή της κρεατινίνης ορού, στον έλεγχο της 1ης μετεγχειρητικής μέρας ανάμεσα στις δύο ομάδες, ωστόσο υπάρχει στατιστικά σημαντική διαφορά ως προς την κάθαρση της κρεατινίνης στον έλεγχο της 1ης μετεγχειρητικής μέρας ανάμεσα στις δύο ομάδες (ομάδα κρεατινίνης <1,3 mg/dl 89,44 ± 35,20 ml/min/1,73m² έναντι ομάδα κρεατινίνης >1,3 mg/dl 53,42 ± 23,37 ml/min/1,73m² p<0,0001). Αναφορικά με τις τιμές των γαλακτικών, ως κύριου δείκτη αναερόβιου μεταβολισμού, και τη μέτρησή τους σε συγκεκριμένες χρονικές στιγμές, διακρίνεται στην περίπτωση της ενδαγγειακής θωρακικής αποκατάστασης, αύξηση των γαλακτικών, σε σχέση με την ενδαγγειακή αποκατάσταση κοιλιακής αορτής (LACTATES 3 – EVAR 1,23 ± 0,04 έναντι TEVAR 2,56 ± 0,80, P<0,002, LACTATES 4 – EVAR 1,23 ± 0,08 έναντι TEVAR 2,04 ± 0,41, P<0,004). Με την ειδικότερη σύγκριση των αποτελεσμάτων ανάμεσα στα διαφορετικά είδη αναισθησίας διακρίνεται η ευεργετική επίδραση της περιοχικής αναισθησίας (ραχιαία αναισθησία ή συνδυασμός ραχιαίας και επισκληριδίου) στην ηπιότερη εμφάνιση των μεταβολικών διαταραχών. Τέλος διαπιστώνεται ότι υπάρχει συσχέτιση ανάμεσα στις διαδοχικές μετρήσεις γαλακτικών και την εμφάνιση επιπλοκών. Και ως επιπλοκές καταγράφηκαν μεγάλες ανακατανομές όγκων με διεγχειρητικές απώλειες αίματος, και συνοδό χορήγηση παραγώγων αίματος, ενδεχόμενη ισχαιμία του σκέλους ή επανεγχείρηση του ασθενούς. Συμπεράσματα. Στη μελέτη μας η κάθαρση της κρεατινίνης ως πρόσθετης παραμέτρου ελέγχου νεφρικής λειτουργίας, θεωρείται ακριβέστερος δείκτης σε σχέση με την κρεατινίνη του ορού. Αυτό πιστοποιείται καθώς σύμφωνα με τη σύγκριση των δύο διαφορετικών ομάδων (ομάδα κρεατινίνης < 1,3 mg/dl έναντι ομάδας κρεατινίνης >1,3 mg/dl), υπάρχει στατιστικά σημαντική διαφορά ως προς την κάθαρση της κρεατινίνης στον έλεγχο της 1ης μετεγχειρητικής μέρας ανάμεσα στις δύο ομάδες, ενώ δεν υπάρχει στατιστικά σημαντική διαφορά ως προς την τιμή της κρεατινίνης ορού. Είναι αναγκαία η εφαρμογή και η τήρηση ενός πρωτοκόλλου προστασίας της νεφρικής λειτουργίας, πριν την ενδαγγειακή επέμβαση. Διαπιστώνεται ότι ενώ δεν υπάρχει συσχέτιση ανάμεσα στις μεταβολές της κρεατινίνης, της κάθαρσης κρεατινίνης και της έκβασης των ασθενών, ωστόσο υπάρχει συσχέτιση ανάμεσα στις διαδοχικές μετρήσεις γαλακτικών και την έκβαση με την εμφάνιση επιπλοκών (όπου επιπλοκές = διεγχειρητικές απώλειες αίματος, συνοδός χορήγηση παραγώγων αίματος, ενδεχόμενη ισχαιμία του σκέλους ή επανεγχείρηση του ασθενούς). Σε σχέση με τη χειρουργική τεχνική, στην ενδαγγειακή αποκατάσταση ανευρύσματος θωρακικής αορτής έχουμε μεγαλύτερη παραγωγή ούρων και αυξημένες τιμές γαλακτικών σε σχέση με την ενδαγγειακή αποκατάσταση κοιλιακής αορτής. Σε σχέση με τη αναισθητική τεχνική, στη ραχιαία έχουμε μικρότερη διούρηση σε σχέση με τη γενική αναισθησία, όπως και πιο ήπιες μεταβολικές διαταραχές στην περιοχική αναισθησία.

ABSTRACT Background Matrix metalloproteinase-3 (MMP-3) plays a key role in development of cancer. The purpose of this study was to assess MMP-3 in the serum and saliva of patients with oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC). Materials and methods Thirty patients with OLP (8 reticular and 22 erosive forms), and 20 patients with OSCC (6 in low stage and 14 in advanced stage), were enrolled in this study, conducted at the Cancer Department, Clinic of Oral Medicine, Tehran University of Medical Sciences. The serum and saliva MMP-3 was assayed by ELISA method. Statistical analysis of the Student's t-test, ANOVA and Pearson correlation coefficient was performed. The mean saliva and serum levels of MMP-3 were significantly higher in patients with OSCC compared with OLP. Results The serum and saliva MMP-3 concentrations increased from reticular form of OLP to erosive form of OLP, and increased further to low stage of OSCC and advanced stage of OSCC. Serum MMP-3 correlated significantly with unstimulated (r = 0.310, p = 0.038) and stimulated (r = 0.365, p < 0.026) saliva MMP-3. Conclusion Serum and saliva MMP-3 levels appear associated with OLP and OSCC. How to cite this article Agha-Hosseini F, Mirzaii-Dizgah I, Mahboobi N, Shirazian S, Harirchi I.

<p>The use of camera traps and mammal track search are complementary methods to monitoring species of which is not well documented their natural history, as in the case of medium and large mammals. To ensure its conservation and good management, it is necessary to generate information about the structure of the community and their populations. The objective of the present study was to estimate the diversity, relative abundance and activity patterns of medium and large mammals in a tropical deciduous forest located in the Isthmus of Tehuantepec, Oaxaca, Mexico. Samplings were conducted in three month intervals, from September 2011 to May 2013. We used photographic-sampling and track search, two complementary sampling methods. For photographic-sampling, 12 camera traps were placed covering an area of 60km<sup>2</sup>, while for the tracks search a monthly tour of four line-transect surveys of three kilometers length each was undertaken. We obtained a total of 344 pictures with 5 292 trap-days total sampling effort; in addition, 187 track records in a total of 144km. With both methods we registered 21 species of mammals, in 13 families and seven orders, and five species resulted in new records to the area. The diversity index of Shannon-Wiener obtained with the method of tracks was H´=2.41, while the most abundant species were <em>Urocyon cinereoargenteus</em> (IAR=0.23) and <em>Pecari tajacu</em> (IAR=0.20). By the method of trap the most abundant species were <em>P. tajacu</em> (IAR=2.62) and <em>Nasua narica</em> (IAR=1.22). In terms of patterns of activity <em>P. tajacu</em>, <em>N. narica</em> and <em>Odocoileus virginianus</em> were primarily diurnal species; <em>Canis latrans</em> and <em>Leopardus pardalis</em> did not show preference for any schedule in particular, and <em>Didelphis virginiana</em> and <em>Dasypus novemcinctus</em> preferred to have nocturnal activity. This information can be of help to the creation of programs of management and conservation of mammals of medium and large in the Isthmus of Tehuantepec, Oaxaca, México.</p>

Introduction. At present, at perinatal medicine, the monitoring has significant role. It is a main instrument for baby care. The use of supervision methods such as biophysical profile of foetus or modified biophysical profile, cardiotocography and ultrasound are standard proceedings on obstetrical units, leading to mothers, foetus and infants safety increase. Aim. The aim of this project is to show relations between incorrect biophysical profile of a foetus and an infant's condition after delivery. Material and methods. The analysis of live births from 1st January 2006 to 31st December 2008 in Gynaecological/Obstetric Clinic of CZMP Institute in Łódź, analysis of women’s giving birth at least in 30 week documents, 1000 infants and their 934 mothers, so it gave the group of 1934 people. Statistical calculations: Test Chi2, Student’s t test and the Pearson correlation coefficient. Results. In group of infants with incorrect biophysical profile avarage parameters were: weigh 2227 g, Apgar score 7.53, hospitalisation time 13.29 days, Caesarean section 68%, and 72% of examinated infants were treated in Neonatology Clinic. Conclusions. 1. Infants with incorrect biophysical profile parameters in comparison with the group of infants with correct biophysical profile have lower body mass (p = 0.01129 < 0.05; Rp = ~5% wan), lower Apgar score (p = 0.0490 < 0.05; Rp = ~3% wan) and longer hospitalisation time (p = 0.0002 < 0.05; Rp = ~26% mild). 2. An incorrect biophysical profile often indicates Caesarian section or forceps delivery (Rp = ~10% wan) and binds to necessity of newborn’s treatment in Neonatology Clinic (Rp = ~27% mild).

Preeclampsia is a multisystem disorder that can manifest clinically with hypertension and proteinuria. Previous studies reported the presence of placental PSA in normal pregnancy but no study has been done in preeclampsia. The aim of this study was to investigate PSA content in preeclampsia. Preeclampsia was diagnosed according to the American College of Obstetricians and Gynecologists criteria. Placentas were obtained from 33 preeclamptic and 34 normotensive women. Placenta samples were homogenized and the supernatants were immediately analyzed. The tissue PSA content was measured by Immulite 2000 PSA assay. The data were analyzed with Student's t-test and Pearson correlation test. There was a significant difference in placental PSA content between preeclamptic and normotensive women. Placental content of PSA was higher in the preeclamptic group with intrauterine growth restriction (IUGR) than in the preeclamptic and normotensive pregnant without IUGR groups. No significant difference was found in this respect between preeclamptic and normotensive women without IUGR. In conclusion, we found that placental PSA content is elevated in preeclampsia and negatively correlated with infant birth weight. Further studies will be necessary to define the roles of PSA more precisely and to examine its effects on the pathophysiology of preeclampsia.

An experiment was conducted in a primary forest area of the Tropical Forest Experimental Station, 45 km from Manaus-Boa Vista Highway, in order to compare the insect fauna of the subfamily Scolytinae, in flight activity and on the ground. Five impact traps of the type Escolitideo/Curitiba, with ethanol baits, were installed at the height of 3 m above the ground, and five pitfall traps were buried in the same area of the above ground traps. The data collections were evaluated through abundance, richness, and Simpson diversity index, and, to compare these data with the pitfalls and the months collection, the ANOVA was used. The Pearson correlation test was also carried out to evaluate the meteorological factors (temperature and rainfall). From the total of 2,910 Scolytinae, 2,341 were captured in pitfall traps representing 80.45% and 569 with Escolitideo/Curitiba traps representing 19.55%. The most abundant species in the collections wereXyleborus volvulusFabricius andXyleborus affinisEichhoff, and this was classified as constant in both habitats. The result of the analysis indicates that the Simpson’s index was high and that the abundance of insects was affected by the types of trap and by the month of collection. The analysis of correlation with meteorological factors showed that onlyXyleborus spinulosusspecies presented significant correlation with temperature.
