Bovine Spongiform Encephalopathy and Public Health
Η σπογγιόμορφη εγκεφαλοπάθεια των βοοειδών είναι μεταδοτική εκφυλιστική νόσος του κεντρικού νευρικού συστήματος και ανήκει σε ομάδα ασθενειών, οι οποίες προσβάλλουν τον άνθρωπο και διάφορα είδη ζώων και έχουν παρόμοια ιστοπαθολογική εικόνα. Ο βλαπτικός παράγοντας της BSE, αλλά και όλων των άλλων σπογγιόμορφων εγκεφαλοπαθειών, δεν έχει πλήρως διευκρινιστεί. Η επικρατέστερη σήμερα άποψη είναι ότι αυτός αποτελείται κυρίως ή και μόνον από μη φυσιολογική πρωτεΐνη, που ονομάστηκε prion. Στις διάφορες παρατηρήσεις ο βλαπτικός παράγοντας γίνεται αντιληπτός με τη μορφή πρωτεϊνικών κυλίνδρων, οι οποίοι αποτελούνται από συγκεντρώσεις ή πολυμερισμένη μορφή του βλαπτικού παράγοντα και ονομάστηκε πρωτεΐνη prion (prion protein - PrP). Αποδείχθηκε ότι υπάρχουν δυο ισόμορφες της PrP. Η μία που σημειώνεται ως PrF παράγεται από αρκετά κύτταρα του ανθρώπου και των ζώων και αποτελεί κυτταρικό δομικό στοιχείο. Η δεύτερη που σημειώνεται ως PrPst παρουσιάζει ιδιαίτερες ιδιότητες, που την καθιστούν παθολογική και υπεύθυνη για τη δημιουργία των σπογγιόμορφων εγκεφαλοπαθειών. Ο αναδιπλασιασμός της PrPM φαίνεται ότι διενεργείται στα λυσοσώματα κυττάρων του νευρικού συστήματος και των δενδριτικών, καθώς και λοιπών κυττάρων του δικτυωτού των λεμφοκυτογόνων οργάνων με μετατροπή της PrPc σε PrPsc. Όπως φαίνεται η BSE προκλήθηκε στα βοοειδή εξαιτίας της κατανάλωσης από αυτά κρεαταλεύρων και οστεαλεύρων, που προέρχονταν από πρόβατα μολυσμένα από τη scrapie. Αναφορικά με την παθογένεια φαίνεται από πειραματικά δεδομένα ότι αρχικά η PrPsr εισέρχεται με την τροφή και εγκαθίσταται στα διάφορα λεμφοκυτογόνα όργανα όπου και γίνεται ο πρώτος αναδιπλασιασμός της. Πιστεύεται ότι, από τα λεμφοκυτογόνα όργανα, μεταφέρεται με τα νεύρα στο κεντρικό νευρικό σύστημα, όπου και δημιουργεί τις χαρακτηριστικές αλλοιώσεις της κενοτοπιώδους εκφύλισης των νευρικών κυττάρων και τη σπογγίωση, οπότε και εμφανίζεται κλινικά η νόσος. Τα νευρικά συμπτώματα χαρακτηρίζονται κυρίως από αλλαγή στη συμπεριφορά των ζώων και από κινητικές ανωμαλίες. Η διάγνωση της νόσου γίνεται με την παρατήρηση των ιστοπαθολογικών αλλοιώσεων, την ανίχνευση ινιδίων συνδεμένων με τη scrapie-SAF και την ανοσοϊστοχημική ανίχνευση των μορίων της PrPsc σε ιστολογικές τομές ή με ηλεκτροφόρηση (Western blotting test). Η BSE αποδείχθηκε ότι μπορεί να μεταδοθεί σε άλλα ζώα και υπάρχει η πιθανότητα να μεταδίδεται και στον άνθρωπο με την τροφική αλυσίδα. Ύστερα από αυτά και σ' όλο το διάστημα που διέρρευσε, απότην εμφάνιση της μέχρι σήμερα, λήφθηκαν μέτρα, τόσο από τη Μ. Βρεττανία, όσο και από την ΕΕ για την εκρίζωση της νόσου και την προστασία της δημόσιας υγείας. Τα μέτρα αυτά θα πρέπει να τηρούνται από τις επίσημες αρχές και επιπρόσθετα θα πρέπει να ενημερωθεί ο καταναλωτής για την πιθανή επικινδυνότητα των διαφόρων ζωικών προϊόντων.Bovine Spongiform Encephalopathy (BSE) is a transmissible degenerative disease of the central nervous system. It belongs to a group of diseases which affect man and various kinds of animals and they have a similar histopathological appearance. The harmful agent of BSE and all the others spongiform encephalopathies have not been totally clarified. Today according to the predominant opinion this agent is consisted mainly or/and only of an abnormal protein, which is called prion. In various observations the harmful agent appears like proteinaceous cylinders which are consisted of aggregations or polymerized forms of the agent and it is called prion-protein (PrP). It has been proved that there are two isoforms of PrP. The first of them, called PrPc, is produced from many cells of man and animals and consists a cellular structural element. The second, called PrPs t, due to its specific properties, it is considered to be pathological and responsible for the spongiform encephalopathies. The replication of PrPsc seems to take place in the lysosomes of central nervous system cells, dendritic, and other reticular cells of the lymphatic organs through transformation of PrPc into PrPsc. It appears BSE caused by feeding meat and bone meals to cattle which were originated from scrapie infected sheep. Refering to the pathogenesis originating from experimental data it seems that initially the PrF* enters the body by food and afterwards is settled in various lymphoid organs where the first replication takes place. It is believed that BSE is transmitted through the nerves to the CNS, where it creates the characteristic lesions of vacuolar degeneration of the neurons and finally the spongiosis. Then the clinical signs are expressed. The nervous signs characterised by behavioural alterations of the animals and kinetic abnormalities. The diagnosis of the disease is made by the observation of the histopathological lesions, the detection of Scrapie Associated Fibrils-SAF by EM, the immunohistochemical detection of prpsc i n histological samples or by electrophoresis (Western blotting test). BSE was proved to be transmissible to other animals and there is a possibility that it could be done to man through the food chain. According to the above in these years, from the appearance of the disease until now, have been taken bans from Great Britain as well as from E.U. for the eradication of the disease and the protection of the public health. These instructions should be followed by the authorities and additionally the consumers ought to be informed for the possible danger of various animal products
Analysis of genome-wide DNA arrays reveals the genomic population structure and diversity in autochthonous Greek goat breeds
Goats play an important role in the livestock sector in Greece. The national herd consists mainly of two indigenous breeds, the Eghoria and Skopelos. Here, we report the population structure and genomic profiles of these two native goat breeds using Illumina's Goat SNP50 BeadChip. Moreover, we present a panel of candidate markers acquired using different genetic models for breed discrimination. Quality control on the initial dataset resulted in 48,841 SNPs kept for downstream analysis. Principal component and admixture analyses were applied to assess population structure. The rate of inbreeding within breed was evaluated based on the distribution of runs of homozygosity in the genome and respective coefficients, the genomic relationship matrix, the patterns of linkage disequilibrium, and the historic effective population size. Results showed that both breeds exhibit high levels of genetic diversity. Level of inbreeding between the two breeds estimated by the Wright's fixation index FST was low (Fst = 0.04362), indicating the existence of a weak genetic differentiation between them. In addition, grouping of farms according to their geographical locations was observed. This study presents for the first time a genome-based analysis on the genetic structure of the two indigenous Greek goat breeds and identifies markers that can be potentially exploited in future selective breeding programs for traceability purposes, targeted genetic improvement schemes and conservation strategies

Two-way trafficking of Annexin V positive cells between mother and fetus: determination of apoptosis at delivery
Objectives The aim of this study was to quantitate apoptosis in maternal
circulation and umbilical cord blood (UCB) at delivery. The proportion
of fetal cells in maternal blood as well as that of maternal cells in
UCB was also determined.
Material and Methods Three milliliters of peripheral blood was collected
from nine women during labor. Five women delivered males and four
delivered females. Immediately after delivery, 3 mL UCB was collected.
Ten microliters was used to quantitate apoptosis by the ethidium bromide
assay (EthBr) and from the remaining blood, Annexin V positive cells
were isolated by MACS.
Results The Median apoptosis rate in maternal samples was 25% (19-34)
and in UCB 20% (16-28). Annexin V positive cells were present in all
samples analyzed. As shown by Fluorescence in situ hybridization (FISH)
in maternal samples, cells with an XY hybridization pattern were
identified in cases with male newborns in a median concentration of
1.7% (1.6-2.1). On the corresponding UCB, a median of 1.2% (0.8-1.6)
XX cells were detected.
Conclusion The study demonstrates the existence of a bidirectional
transfer of fetal and maternal cells under apoptosis across the placenta
and provides useful information regarding use of UCB for
transplantation. Copyright (c) 2007 John Wiley & Sons, Ltd
Unique Peptides of Cathelicidin-1 in the Early Detection of Mastitis—In Silico Analysis
Based on the results of previously performed clinical studies, cathelicidin-1 has been proposed as a potential biomarker for the early diagnosis of mastitis in ewes. It has been hypothesized that the detection of unique peptides (defined as a peptide, irrespective of its length, that exists in only one protein of a proteome of interest) and core unique peptides (CUPs) (representing the shortest peptide that is unique) of cathelicidin-1 may potentially improve its identification and consequently the diagnosis of sheep mastitis. Peptides of sizes larger than those of the size of CUPs, which include consecutive or over-lapping CUPs, have been defined as ‘composite core unique peptides’ (CCUPs). The primary objective of the present study was the investigation of the sequence of cathelicidin-1 detected in ewes’ milk in order to identify its unique peptides and core unique peptides, which would reveal potential targets for accurate detection of the protein. An additional objective was the detection of unique sequences among the tryptic digest peptides of cathelicidin-1, which would improve accuracy of identification of the protein when performing targeted MS-based proteomics. The potential uniqueness of each peptide of cathelicidin-1 was investigated using a bioinformatics tool built on a big data algorithm. A set of CUPs was created and CCUPs were also searched. Further, the unique sequences in the tryptic digest peptides of cathelicidin-1 were also detected. Finally, the 3D structure of the protein was analyzed from predicted models of proteins. In total, 59 CUPs and four CCUPs were detected in cathelicidin-1 of sheep origin. Among tryptic digest peptides, there were six peptides that were unique in that protein. After 3D structure analysis of the protein, 35 CUPs were found on the core of cathelicidin-1 of sheep origin and among them, 29 were located on amino acids in regions of the protein with ‘very high’ or ‘confident’ estimates of confidence of the structure. Ultimately, the following six CUPs: QLNEQ, NEQS, EQSSE, QSSEP, EDPD, DPDS, are proposed as potential antigenic targets for cathelicidin-1 of sheep. Moreover, another six unique peptides were detected in tryptic digests and offer novel mass tags to facilitate the detection of cathelicidin-1 during MS-based diagnostics
