Background and objectives: Olive pâté (OP) is an olive-derived product with potentially beneficial effects on human health due to the presence of natural antioxidants. The present dietary supplementation study aimed to evaluate the effects on blood antioxidant levels of an olive pâté reinforced with natural antioxidants (ROP) recovered from olive mill waste. Materials and methods: Ninety-eight healthy volunteers (M = 54, 55%, age 18–25) were divided into two groups: A (n = 49), practicing three or more days of physical activity a week, and B (n = 49), practicing less than two. Each group was split into two subgroups, receiving dietary supplementation with OP or ROP. The status of smoker was also recorded, and a biological antioxidant potential (BAP) test was performed on each subject. Results: The BAP values increased with both OP (n = 30) and ROP (n = 68) but ROP supplementation showed higher increments (736.9 μmol/L) than OP (339.6). The increment was significantly higher for smokers (n = 15), 1122.9 vs. non-smokers (n = 53), 635.7, with values in percent of baseline, respectively, 34.6% and 16.2% (P < 0.01). Conclusions: The ROP nutritional supplementation appears useful to increase antioxidant activity, with better effect in smokers; further studies should confirm the finding and investigate its biological bases.

Abstract Background : Previously,we showed that serum malondialdehyde (MDA) was significantly higher in patients with neovascular age-related macular degeneration (nAMD) than in those without AMD. The Diacron reactive oxygen metabolites(d-ROMs) andbiologicalantioxidant potential (BAP) tests are known markers ofoxidative stress. The aim of this study was to use d-ROMs and BAP tests to evaluate changes in systemic oxidative stressin patients with nAMD. Methods : Blood serum samples were collected from 34 patients with nAMD (mean age: 76.5 ± 7.7 years; 22 men) and 20 control subjects (mean age: 62.9± 14.0 years; 10 men), and d-ROMs and BAP tests were examined. Results : In men, the mean level of d-ROMs for the nAMD patients was significantly higher than that for the controls (312.0 ± 52.4 vs. 275.1 ± 45.5 U.CARR, respectively; P < .05). There was a significant correlation between d-ROM level and CNV lesion area in the male nAMD group (r =.42, P = .05). There were no significant differences in mean BAP test results between the nAMD patients and controls for either sex (men: 2241 ± 549 vs. 2136 ± 246 μmol/L; women: 2263 ± 292 vs. 2335 ± 161 μmol/L). Conclusion : The d-ROMs test may provide a useful indicator of nAMD in men but not in women.

The present study was conducted to assess the chemical composition of Yellow Maca (Lepidium meyenii) and its biological activity on stallions following oral administration of hypocotyl powder. Maca was subjected to methanolic extraction and the chemical analysis was carried out by LC-MS-QTOF (liquid chromatography-mass spectrometry). Our results showed that Maca contains some effective antioxidants, a high percentage of glucosinolates, and other important components with a high antioxidant capacity. To evaluate the plant biological activity in stallions fed with Maca powder for 60 days, the redox status and some reproductive parameters were investigated. Blood and semen samples were collected at 0, 30, 60, and 90 days from the beginning of this study. Blood samples showed a decrease of the reactive oxygen metabolites, evaluated by d-ROMs test, and an increase of the antioxidant barrier in terms of biological antioxidant potential (BAP test), powerful oxidant capacity (OXY-Adsorbent test), and thiols evaluation (-SHp test). Furthermore, semen samples showed a positive trend during Maca administration in the following parameters: ejaculate volumes and sperm concentrations, total and progressive motility, and acrosome integrity.

Background: Inflammatory bowel diseases (IBD), which include Crohn’s disease (CD) and ulcerative colitis (UC), are described as a chronic inflammation of the small intestine and colon, caused by a dysregulated immune response to host intestinal microbiota in genetically susceptible subjects. Objective: The aim of this study was to compare probiotic therapy versus placebo in Oxidative Stress Values and clinical features in patients affected by IBD. Method: Forty (40) patients previously diagnosed for IBD were recruited and randomized to receive probiotics (test group, n=20) or placebo (control group, n=20) administered for 90 days. Subjects in both the groups were assessed for overall oxidant ability (d-ROMs test) and for the antioxidant response (BAP test): data were reported at baseline, after 1 and 3 months. Additional data from anamnesis and haematological investigation were also reported during the study. Results: d-ROM assay clearly showed that the values observed in the test group were significantly improved, leading to oxidative stress values which are not pathological. The test group showed increasing BAP values, thus confirming the overall improvements of patients ‘health following administration of probiotics. Conclusion: Oral administration of the specific probiotics demonstrated its efficacy and safety on patients affected by IBD.

Background: The aim of this study was to evaluate the effects of 72-h sleep deprivation on normal daily activities (work, family, and sports), and to investigate whether sleep can be chronically reduced without dangerous consequences. Methods: The participant in this study was an adult male (age 41 years; mass 69 kg; height 173 cm). During the 72 h, data were collected every 6 h, involving a baseline (pre-deprivation). We monitored various parameters: Oxidative Stress (D-Rom and Bap test), Psychological Responses (test POMS and Measure of Global Stress), Metabolic expenditure (kJ) using a metabolic holter, EEG records, Cortisol, and Catecholamines level. Results: An interesting result was observed in the post-test phase, when a brief moment of deep sleep and total absence of a very deep sleep occurred, while an almost normal condition occurred in the pre-test sleep. Conclusion: During the 72-h sleep deprivation, no psycho-physiological stress was recorded. The participant has remained within the threshold of well-being. Only a peak was recorded during the 66th hour, but it was within the wellness threshold.

H αναπαραγωγική διαδικασία είναι μία κρίσιμη, βιολογικά ενεργειοβόρα διαδικασία, η οποία διαταράσσει, προσωρινά, την ομοιοστασία του οργανισμού. O σκοπός της παρούσας έρευνας ήταν η μελέτη των μεταβολών των αιματολογικών και βιοχημικών παραμέτρων, των ορμονών του θυρεοειδούς αδένα και της οξειδοαναγωγικής κατάστασης του αίματος των κριών, κατά την αναπαραγωγική δραστηριότητα στη διάρκεια ενός προκληθέντος οίστρου. Στη μελέτη εντάχθηκαν 37 ενήλικοι κριοί, οι οποίοι πληρούσαν αυστηρά κριτήρια και κατανεμήθηκαν σε δύο ομάδες (Ομάδα Α, κριοί Χίου, n=19 και Ομάδα Β, κριοί Φλωρίνης, n=18). Κάθε κριός πραγματοποιούσε κατά βούληση συζεύξεις με 10 θηλυκά πρόβατα της αντίστοιχης φυλής, στα οποία είχε πραγματοποιηθεί συγχρονισμός του οίστρου. Αιμοληψίες διενεργούνταν πριν την έναρξη της αναπαραγωγικής δραστηριότητας (χρονική στιγμή Τ0), κατά τη διάρκειά της (24, 48 και 72 ώρες μετά την Τ0) και μετά το πέρας αυτής (1 εβδομάδα μετά την Τ0). Στους κριούς πραγματοποιούνταν γενική εξέταση αίματος (Advia 120, Siemens Healthcare Diagnostics, USA) και κυτταρολογική εξέταση του επιχρίσματος του αίματος. Οι αναλυτές Flexor E (Vital Scientific N.V., The Netherlands) και AVL 9180 Electrolyte Analyzer (Roche Diagnostics, Belgium) χρησιμοποιήθηκαν για την πραγματοποίηση των βιοχημικών εξετάσεων στον ορό του αίματος. Συγκεκριμένα, προσδιορίστηκαν οι συγκεντρώσεις των εξής παραμέτρων: ολικές πρωτεΐνες, λευκωματίνη, σφαιρίνες, γλυκόζη, χοληστερόλη, τριγλυκερίδια, ολικό ασβέστιο, ανόργανος φωσφόρος, κάλιο, νάτριο, ουρία, κρεατινίνη και ολική χολερυθρίνη, καθώς και οι δραστηριότητες των ενζύμων ALT, AST, ALP, GGT, CK και LDH. Ο αναλυτής Immulite 1000 (Siemens Healthcare Diagnostics, USA) χρησιμοποιήθηκε για τη μέτρηση της συγκέντρωσης της θυροξίνης στον ορό. Ο έλεγχος της οξειδοαναγωγικής κατάστασης του αίματος πραγματοποιήθηκε με τη χρησιμοποίηση των d-ROMs Test (Diacron Labs S.r.I., Italy) και BAP Test (Diacron Labs S.r.I., Italy) και τη βοήθεια του αναλυτή Free Carpe Diem (Diacron Labs S.r.I., Italy). Χωριστά μικτά μοντέλα επιδράσεων χρησιμοποιήθηκαν για τη μελέτη της επίδρασης των παραγόντων Ομάδα και Χρόνος στις εξαρτημένες μεταβλητές (R, R Foundation for Statistical Computing, Austria). Σε κάθε μοντέλο έγινε έλεγχος για την ύπαρξη στατιστικά σημαντικής αλληλεπίδρασης μεταξύ των δύο παραγόντων (Ομάδα×Χρόνος), αλλά και κύριων επιδράσεων των δύο παραγόντων (Ομάδα και Χρόνος) στην υπό μελέτη παράμετρο. Υπό τις συνθήκες του πειράματός μας, η αναπαραγωγική δραστηριότητα συνδέεται με πολυάριθμες αιματολογικές, βιοχημικές, ορμονικές και οξειδοαναγωγικές μεταβολές. Η έντονη αναπαραγωγική δραστηριότητα αποτελεί μία φυσική δραστηριότητα, η οποία προκαλεί ήπια μυϊκή βλάβη και συνδέεται με παρουσία οξειδωτικού στρες στους κριούς Φλωρίνης, ενώ αντιθέτως, η κριοί Χίου αποδεικνύονται ανθεκτικοί, πιθανότατα λόγω του υψηλότερου αντιοξειδωτικού δυναμικού τους και της ικανότητάς τους να ενισχύουν την αντιοξειδωτική τους άμυνα. Εν γένει, οι παρατηρούμενες εργαστηριακές μεταβολές είναι συμβατές με αυτές που έχουν αναφερθεί σε διάφορες μορφές φυσικής δραστηριότητας και άσκησης στα ζώα και στον άνθρωπο και αντικατοπτρίζουν, κυρίως, την αυξημένη έκκριση κατεχολαμινών ή/και κορτιζόλης, τη σχετιζόμενη με την περίοδο αποκατάστασης διόγκωση του πλάσματος του αίματος και τη μειωμένη αιματική ροή των εσωτερικών οργάνων προς όφελος των υπερλειτουργούντων μυών. Επιπλέον, εικάζεται ότι το αναπαραγωγικό ένστικτο υπερισχύει προσωρινά του ενστίκτου της πείνας, επιδρώντας ήπια στον μεταβολισμό των κριών. Η παρούσα έρευνα αποτελεί την πρώτη ευρείας έκτασης μελέτη των εργαστηριακών μεταβολών που συνοδεύουν την αναπαραγωγική δραστηριότητα των αρσενικών και τα αποτελέσματά της θα πρέπει να επιβεβαιωθούν από μελλοντικές έρευνες.

Abstract This study aimed to investigate antioxidant and anti-inflammatory activities of a commercial product of noni (Morinda citrifolia) juice. Carrageenan-induced rat paw edema was employed as inflammatory model. One control and three experimental groups were formed. Experimental groups were administered noni juice alone, noni juice+carrageenan, and carrageenan alone. Oxidant and antioxidant capacity were determined by d-ROMs test and BAP test, respectively. Plasma concentrations of endothelin-1 and leptin were measured by ELISA. Measurements were performed at zero time and 2nd hour of inflammation. Oxidant capacity decreased in noni-received groups at 2nd hour (p=0.019). Antioxidant capacity of the group which received noni alone was found to be higher at 2nd hour (p=0.036). Plasma concentrations of endothelin-1 and leptin were notably lower in noni-received groups (p=0.001 and p=0.021, respectively). The results show that the commercial noni juice investigated has pronounced antioxidant and anti-inflammatory activities.
