CD166 expression in dentigerous cyst, keratocystic odontogenic tumor and ameloblastoma.
2015
Background CD166 is a glycoprotein of an immunoglobulin super family of adhesion molecules that has been associated with aggressive characteristics and high recurrence rate of tumors. Different odontogenic lesions exhibit considerable histological variation and different clinical behavior. In an attempt to clarify the mechanisms underlying this different behavior, the present study investigates the immunohistochemical expression of CD166 in these lesions. Material and Methods In this study 69 formalin-fixed, paraffin embedded tissue blocks of odontogenic lesion consist of 15 unicystic ameloblastoma (UA), 17 solid ameloblastoma (SA), 18 keratocystic odontogenic tumors (KCOT), and 19 dentiger…
Not just the sum of its parts : Geographic variation and nonadditive effects of pyrazines in the chemical defence of an aposematic moth
2022
Chemical defences often vary within and between populations both in quantity and quality, which is puzzling if prey survival is dependent on the strength of the defence. We investigated the within- and between-population variability in chemical defence of the wood tiger moth (Arctia plantaginis). The major components of its defences, SBMP (2-sec-butyl-3-methoxypyrazine) and IBMP (2-isobutyl-3-methoxypyrazine), are volatiles that deter bird attacks. We hypothesized that (1) variation in the chemical defences of male wood tiger moths reflects the local predation pressure; (2) observed differences in quantity and quality of defence among populations have a genetic basis; and (3) increasing con…
Prosthetic rehabilitation with dental implants after treatment of a keratocystic odontogenic tumor. Case report
2011
Keratocystic odontogenic tumor (KCOT), formerly known as the odontogenic keratocyst (OKC) is a benign intraosseous lesion, characterized by invasive growth and high rate of recurrences. Although it is not frequently seen, KCOT may be associated with unerupted teeth and without relevant histopathological examinations, might be mistaken with dentigerous cyst. A 26 year-old male patient referred to our department with complaints of two months persisting painless swelling on the left side of mandible. Clinical and radiographic examinations revealed an impaction of the horizontally positioned left lower second premolar surrounded by a well-circumscribed radiolucent mass, located between the left…
Non-endodontic periapical lesions clinically diagnosed as endodontic periapical lesions: A retrospective study over 15 years
2021
Background This study aimed to provide the frequency and demographic data of non-endodontic periapical lesions clinically misdiagnosed as endodontic periapical lesions from a Southeast Asian population over a 15-year period. Material and methods A retrospective study was conducted from departmental archives between 2005 and 2019. Cases clinically diagnosed as endodontic periapical lesions were retrieved. Then, cases with a histopathological diagnosis of non-endodontic periapical lesion were selected. Demographic data of non-endodontic periapical lesions were recorded. Radiographic features of cases with available radiographs were analyzed. Results Of 1,566 cases clinically diagnosed as endo…
Thermal and non-thermal preservation techniques of tiger nuts' beverage "horchata de chufa". Implications for food safety, nutritional and quality pr…
2017
"Horchata de chufa" is a traditional Spanish beverage produced from tiger nuts (Cyperus esculentus L.). Due to its richness in nutritional compounds, it is highly perishable and its conservation by pasteurization and/or adding preservatives is required. Although efficient, conventional thermal treatment for pasteurization induces changes in the nutritional and sensory properties. Replacing conventional pasteurization by non-thermal technologies such as pulsed electric fields, ultraviolet, and high pressure, combined with moderate temperatures (<40°C) allows a reduction of energy consumption, along with the preservation of the most thermo-sensitive molecules. Accordingly, this review deals w…
Trade-off between warning signal efficacy and mating success in the wood tiger moth
2011
The coloration of species can have multiple functions, such as predator avoidance and sexual signalling, that directly affect fitness. As selection should favour traits that positively affect fitness, the genes underlying the trait should reach fixation, thereby preventing the evolution of polymorphisms. This is particularly true for aposematic species that rely on coloration as a warning signal to advertise their unprofitability to predators. Nonetheless, there are numerous examples of aposematic species showing remarkable colour polymorphisms. We examined whether colour polymorphism in the wood tiger moth is maintained by trade-offs between different functions of coloration. In Finland, m…
First report of the bordered straw, Heliothis peltigera, οn sunflower in Greece
2017
Τον Ιούνιο 2015, καταγράφηκαν προσβολές καλλιeργeιών ηλιάνθου από το έντομο Heliothis peltigera (Lepidoptera: Noctuidae) σe αγροτικές πeριοχές της Πeριφeρeιακής Eνότητας Δράμας. Παρατηρήθηκαν διαβρώσeις στα φύλλα και στους οφθαλμούς από τις προνύμφeς του eντόμου, κυρίως στα προανθικά στάδια ανάπτυξης. Οι προσβολές παρατηρήθηκαν στο 80% των αγρών που eπισκοπήθηκαν, ωστόσο το eπίπeδο προσβολής των φυτών ήταν χαμηλό (<5%) και δeν διαπιστώθηκe πρόκληση οικονομικής ζημίας στις καλλιέργeιeς. Το H. peltigera έχeι αναφeρθeί από τη Νότια και Κeντρική Eυρώπη, τον Καναδά, τη Μέση Ανατολή και την Αφρική να προσβάλλeι διάφορους ξeνιστές. Προσβολές σe καλλιέργeιeς ηλιάνθου έχουν αναφeρθeί από την Ινδία, …
Odontogenic Cysts: Analysis of 2.944 cases in Chile
2007
Introduction: Odontogenic cysts constitute a group of frequent intraosseous lesions characteristic in the maxillary bones and one of the main causes of the destruction of these bones. In Chile there are no retrospective studies of these lesions as a whole. Objective: The purpose of this study is to determine the frequency of these lesions in so far as they were diagnosed and registered in the Referral Institute for Oral Pathology (IREPO) of the University of Chile in two age groups as well as to analyze and to compare the data obtained with the data published in previous studies. Material and Method: We studied the records from IREPO of the University of Chile for the period between 1976 an…
Adenomatoid odontogenic tumor : case series of 14 with wide range of clinical presentation
2017
Background To present 14 cases of adenomatoid odontogenic tumor (AOT), highlighting their clinical, radiographic, and histologic characteristics. Material and Methods Fourteen cases of AOT were retrieved from the archives of the Oral Pathology Biopsy Service (OPBS). Clinical, radiologic, and histologic findings are described. Results Fourteen AOT cases were reviewed, of which 12 were intraosseous and two were peripheral (gingiva). The cases came from eight females and six males with an age range of 11-30. Of the 12 intraosseous cases, nine were follicular (associated with impacted teeth), while three were extra-follicular (present between teeth). Six of the 12 cases were in the maxilla, and…
Identification, structure, and properties of hemocyanins from Diplopod myriapoda.
1999
Hemocyanins are copper-containing, respiratory proteins that occur in the hemolymph of many arthropod species. Here we report for the first time the presence of hemocyanins in the diplopod Myriapoda, demonstrating that these proteins are more widespread among the Arthropoda than previously thought. The hemocyanin of Spirostreptus sp. (Diplopoda: Spirostreptidae) is composed of two immunologically distinct subunits in the 75-kDa range that are most likely arranged in a 36-mer (6 x 6) native molecule. It has a high oxygen affinity (P(50) = 4.7 torr) but low cooperativity (h = 1.3 +/- 0.2). Spirostreptus hemocyanin is structurally similar to the single known hemocyanin from the myriapod taxon,…
