Full textThis study compares sexual variation of the human skeletal pelvis through geometric morphometric analyses. Digitization of the skeletal elements provides the framework for a multi-faceted examination of shape. The sample used in the study consists of individuals from the Bass Donated Skeletal Collection, located at the University of Tennessee-Knoxville. Landmarks digitized for the study are derived from the 36 points implemented in Joan Bytheway and Anne Ross’s geometric morphometric study of human innominates (2010). The author hypothesizes that morphological variation between males and females will be visible to varying degrees throughout the pelvis, with structures to be compared consisting of the ilium, ischium, pubis, obturator foramen, and acetabulum. Particular attention will be paid to the pelvic canal, as this area seems to carry the most sex-specific function of the bone. It is hypothesized that structures directly contributing to the pelvic canal will be more sexually dimorphic than peripheral structures. Data points plotted throughout the pelvis will allow for comparison of various regions. Results indicate that the innominate can be divided into modules with relatively low levels of covariation between them. Greatest amounts of sexual dimorphism are located at the pubis and ischium. The shape of the acetabulum and obturator foramen display little variation between the two sexes. Areas that have the potential for sex determination could be investigated more thoroughly in the future and may be of use in forensic cases in which remains are incomplete.

Full textThe aims of this study were to measure: 1. Myometrial cells of menopausal uteri to establish whether they atrophy after the menopause. 2. Myometrial cells at different phases of the menstrual cycle to investigate the influences of oestrogen and progesterone during the cycle. 3. Myometrial cells in the fundus and lower uterine segment to establish whether they differ in size. 4. Myometrial cells of pregnant uteri to investigate the effect of the hormonal status of pregnant women on the size of myometrial cells. 5. Neoplastic cells of leiomyomas of the uterus to investigate whether these benign tumours behave in the same manner as myometrium or, because they are neoplastic, they react differently. A preliminary investigation was undertaken to establish the optimal methodology for this study to measure myometrial and leiomyoma nuclei in the uterus. The aims of this preliminary investigation were: 1. To test the reproducibility of measurements of myometrial and leiomyoma nuclei in transverse and cross section. 2. To test five histological staining methods to ascertain the best method for a morphometric study on uterine cells. 3. To find the minimum sample size of nuclei per section of myometrium or leiomyoma in order to yield statistically significant results. This preliminary study found that the Haematoxylin and Eosin stain gave the most statistically reproducible measurements. Subjective assessment of the five staining methods also found Haematoxylin and Eosin to be optimal. It was also found during the preliminary study that measuring the myometrial nuclei in cross rather than transverse section gave the most statistically reproducible measurements. It was also found that it was best to use an axial ratio criterion of 0,9 when measuring cross-sectioned myometrial nuclei. The optimum sample size per section was also investigated and it was found that measuring 100 nuclei was optimal. It was found that in the uteri used in this study there was no statistically significant decrease in nuclear size after the menopause. It was also found that there was no statistically significant difference in nuclear size during the different phases of the menstrual cycle. There was also no notable difference in nuclear size between nuclei in the fundus and lower segment of the uteri in this study. It was found that there was a significant increase in the size of nuclei in leiomyomas compared to the normal myometrial nuclei from the same patient. The myometrial nuclei from pregnant uteri were also significantly larger than those from non-gravid uteri.

Full textThe morphological variability of dental structures within the different species as well as between the species of sharks belonging to the family of the Carcharhinidae is insufficient investigated. Without knowledge of the species specific parameter the precise taxonomic classification based on the teeth morphology of fossil sharks is kind of impossible. The comprehensive analysis of dental structures of extant carcharhinid sharks was used to transfer the results to their next extinct relatives. Special attention was focused on the comparison between fossil teeth of populations with westatlantic and centralasiatic origin. A morphometric analysis program was established, that is in contrast to traditional methods not based on manual data collection. With the new method of automatic algorithmic morphometry (AAM) the essential species specific attribut complexes were defined for the first time by using the morphological data of 2340 single tooth from 112 individuals from 41 species of extant carcharhinid sharks and transfered to an appropriate new analysis program including all datasets in one database. Individual studies for each single species in aspects like ontogenetic, sexual, mono- and dignatic heterodondity as well as intra- and interspecific variance in tooth morphology proved the possibility to identify carcharhinid sharks just by their teeth and that these attributes can be used for systematic purposes. The effectiveness of the systematic classification stands in direct dependence to tooth position and investigated species. The heterodondity influence for the taxonomic significance is quite high and limiting the taxonomic classification. An enormous bandwith in morphological overlapping and interpenetration is existing as well as within the species but also between species respectively across genus. The comparison based on single teeth with both fossil and extant origin, makes it in many cases impossible to differentiate between intraspecific variance and already existing specific difference. From the new insight to morphological differentiation based on the morphometric analysis (AAM) established in this work and the tranfer from this informations to fossil samples the need for different view to fossil teeth of carcharhinid sharks was obvious. Beside the traditional descriptive procedure of taxonomy a method based on functional morphology is need to better reassess fossil carcharhinid shark teeth. Therefor six functional morphological groups where defined for the first time especially for paleoecological conclusions in the assessment of fossil teeth

Full textSex estimation is a fundamental analysis in the establishment of the biological profile in forensic anthropology. Traditionally, sex estimation of the skull is based on visual interpretation of specific morphological traits and metric analyses (Buikstra and Ubelaker, 1994; Bass 2005; Jantz and Ousley, 2005; Spradley and Jantz, 2011). If morphological traits are large and rugose, the skull is determined to be male, while gracile features and an overall smaller size suggest a female. This type of sex assessment is typically based on ordinal scores of five standard sexually dimorphic traits, including the mastoid process (Buikstra and Ubelaker, 1994). Scores from the visually examined traits are averaged by the analyst to provide a final sex estimate. Recently, legal proceedings in the United States have encouraged quantitative rather than qualitative techniques in scientific fields. As a result, the subjectivity of visual analysis is under scrutiny. The current study aims to determine if metric evaluation of the mastoid process can be utilized as a quantifiable predictor of sex. A modern sample of American Whites and Blacks (n = 157) from the William M. Bass Donated Skeletal Collection was examined. Five bilateral measurements of the mastoid process were recorded and analyzed for accuracy in correct classification of sex. Tests for intraobserver reliability of the measurements were performed on a subsample (n = 24). This study suggests that morphometric analysis of the mastoid process yields reliable, sexually dimorphic values, but with reduced predictive accuracies as compared to visual assessment.

Full textFree-living nematodes have been and are continually considered excellent bioindicators by several authors. Their high structural and functional diversity makes them more diversified and numerically dominant in aquatic habitats, with a wide distribution ranging from untouched habitats to highly polluted habitats. This fact as called the attention of many researchers who in turn motivated and promoted their use in the evaluation of the quality of water bodies. Farther, studies showed that morphometry and biomass are two important aspects to consider in ecological studies of free-living nematodes. The current study focuses on the investigation of the morphometric attributes of the free-living nematodes of the Tagus estuary (Portugal) in order to relate them to the various environmental conditions of the sediment along the estuary. Therefore, the following null hypothesis was tested: There will be no differences in the nematode morphometric parameters (length, width, L / W ratio and biomass) in the different sections of the estuary. Conclusions led to the rejection of the null hypothesis as significant differences were observed along the sections of the estuary for most of the morphometric attributes measurements taking in consideration the six most abundant genera of nematodes in the Tagus estuary (Terschellingia, Sabatieria, Daptonema, Ptycholaimellus, Viscosia and Anoplostoma). Though salinity, depth, grain size variables and organic matter were the environmental variables that were found to be more correlated with the nematode morphometric attributes variance along the estuary, nematode size and shape at investigated sections most likely reflected differences in quality and quantity of organic material and sediment size of the estuary. Most of the variability in terms of nematode morphometry along the Tagus estuary were verified for the genera Terschellingia leading to the conclusion that this genera can provide better information about the different environmental conditions of the sediment along the Tagus estuary
Os nemátodes de vida livre foram e são continuamente considerados ótimos bioindicadores por vários autores. A elevada diversidade estrutural e funcional dos nemátodes de vida livre torna-os o grupo mais diversificado e numericamente dominante em habitats aquáticos, com uma ampla distribuição que varia de habitats intocados a habitats altamente poluídos. Este fato chamou a atenção de muitos investigadores que, por sua vez, motivaram e promoveram o seu uso na avaliação da qualidade das massas de água. Além disso, estudos mostraram que a morfometria e biomassa são dois aspectos importantes a serem considerados em estudos ecológicos de nemátodes de vida livre. O corrente estudo foca-se na investigação dos atributos morfométricos dos nemátodes de vida livre do estuário do Tejo de modo a relacioná-los com as várias condições ambientais do sedimento ao longo do estuário. Para este efeito foi testada a seguinte hipótese nula: Não haverá diferenças nos parâmetros de nemátodes (comprimento, largura, relação C/L e biomassa) em diferentes secções do estuário. As conclusões levaram à rejeição da hipótese nula. Diferenças significativas foram observadas ao longo das seções do estuário para a maioria das medições dos atributos morfométricos dos seis géneros mais abundantes de nemátodes no estuário do Tejo (Terschellingia, Sabatieria, Daptonema, Ptycholaimellus, Viscosia e Anoplostoma). Embora a salinidade, profundidade, tamanho do sedimento e matéria orgânica tenham sido as variáveis ambientais mais correlacionadas com a variância dos atributos morfométricos dos nemátodes ao longo do estuário, o tamanho e a morfologia de nemátodes nas seções investigadas refletiram diferenças na qualidade e quantidade de matéria orgânica e tamanho do sedimento do estuário. A maior parte da variabilidade em termos de morfometria dos nemátodos ao longo do estuário do Tejo foi verificada para o género Terschellingia, levando à conclusão de que este género pode fornecer uma melhor informação sobre as diferentes condições ambientais do sedimento ao longo do estuário do Tejo

Full textSchafe werden häufig als Tiermodell für In-vivo-Versuche verwendet, um neue Wirbelsäulenimplantate sowie chirurgische Prozeduren zu testen. Daher ist die umfassende Kenntnis der präzisen Morphometrie und der biomechanischen Merkmale der Schafwirbelsäule entscheidend für das experimentelle Design und die Interpretation der Ergebnisse in den Studien. Es sind wenige Daten über die Schafwirbelsäule bekannt. Auf Grund dessen zielt die aktuelle Studie darauf ab, mehr Wissen über die Morphometrie der thorakolumbalen Wirbelsäule von Schafen zu gewinnen. Der erste Teil dieser Studie soll die Morphometrie der Brust- und Lendenwirbelsäule dokumentieren. Das Ziel besteht darin, die Verwendung von Schaflendenwirbeln als Modell für die menschliche Wirbelsäule im morphometrischen Vergleich beurteilen zu können. Aus diesem Grund wurden Computertomographische Untersuchungen (CT) von fünf klinisch gesunden weiblichen Merino-Schafen (2 Jahre, 62 kg ± 5,3 kg) unter Allgemeinanästhesie durchgeführt. Die CT-Bilder wurden mit einer Schichtdicken von 1 mm aus T2 bis L6 gewonnen. Anschließend wurden die CT-Bilder in der transversalen und sagittalen Ebene multiplanar reformatiert. Danach wurden Messungen und Bewertungen mit einer geeigneten Software an den Wirbelkörpern, Wirbelkanälen, Bandscheiben und Pedikeln durchgeführt. Basierend auf den erzeugten morphometrischen Daten der Schaflendenwirbel wurden vier Wirbelsäulen-Indizes und Pavlov’s-ratio sowie das Volumen der Wirbelkörper berechnet. Die Wirbelsäulen-Indizes stellten den Konkavitäts-, Endplatten-, Spinalkanal- und Pedikel-Index dar. Für die Messung des Volumens von Wirbelkörpern wurden die transversalen CT-Daten in 5 mm Schichtdicke formatiert und in geeignete Software eingefügt. Danach wurden die vier Indizes-Wirbelsäulen und das Volumen der Lendenwirbelkörper mit den veröffentlichten Daten von menschlichen Wirbeln verglichen. Sie wurden als „vergleichbar“ definiert, wenn das Verhältnis Schaf-Mensch jedes einzelnen Wirbels Variationen von weniger als 20 % aufwies. Der zweite Teil der vorliegenden Arbeit hat zum Ziel, quantitative morphometrische Daten des thorakolumbalen Duralsacks zu ermitteln. Weiterhin sollen die anatomischen Beziehungen zwischen dem Duralsack und seinen umliegenden knöchernen Strukturen der Wirbelsäule beschrieben werden. Dazu wurden CT-Myelographien an fünf erwachsenen weiblichen Schwarzkopfschafen (2 Jahre ± 0,4 Jahre, 80,6 kg ± 28,7 kg) unter Allgemeinanästhesie durchgeführt. Transversale CT-Bilder wurden mit 2 mm Schichtdicke von T1 bis L6 gemessen. Sagittal- und Transversal-Durchmesser sowie die Querschnittsfläche von Duralsack und Wirbelkanal wurden auf CT-Bildern gemessen. Um die anatomische Beziehung zwischen dem Duralsack und den knöchernen Strukturen des Wirbelkanals zu ermitteln, wurden der Pedikel-Duralsack-Abstand und das Platzangebot für den Duralsack berechnet. Die Wirbelkörper und der Wirbelkanal der ovinen thorakolumbalen Wirbelsäule sind breiter als tief, vor allem im Bereich der Lendenwirbel. Die Bandscheiben sind in der Lendenwirbelsäule 57,4 % dicker als in der Brustwirbelsäule. Die Pedikel der Brust- und Lendenwirbelsäule waren höher und länger als breit. Im Vergleich zum Menschen ist das Volumen von Schaflendenwirbelkörpern 48,6 % kleiner. Der Vergleich der absoluten Werte zwischen den beiden Spezies ergab, dass Schafe kleinere, längere und schmalere Wirbelkörper, dünnere Bandscheiben, einen schmaleren Spinalkanal und schmalere, höhere Pedikel besitzen. Der Vergleich der Wirbelsäulen-Indizes zeigte eine gute Vergleichbarkeit mit menschlichen Wirbelendplatten und Wirbelkanälen. Im zweiten Teil der Studie konnte festgestellt werden, dass die Duralsackfläche 45,9 % des Brustwirbelkanals und 49,0 % des Lendenwirbelkanals einnimmt. Die Duralsackfläche korreliert deutlich positiv mit dem Querdurchmesser und der Fläche des Wirbelkanals. Der Pedikel-Duralsack-Abstand in der Lendenwirbelsäule war bis zu 15,8 % größer als in der Brustwirbelsäule

Full textHistoriquement, le travaux de Marcellin Boule ont donné lieu à des représentations populaires de Néandertaliens vus comme des créatures simiesques bestiales qui se déplaçaient courbés avec des genoux pliés en traînant les pieds. Aujourd'hui, il est généralement admis que les Néandertaliens se déplaçaient d'une manière similaire à l'homme moderne avec une locomotion bipède. Toutefois, cette hypothèse n'a pas été encore testée sur un squelette néandertalien dans son ensemble. Comme il n’existe aucun squelette de Néandertalien entier, le but de cette thèse était de reconstituer un squelette virtuel complet sur la base des restes de Spy II à des fins éducatives de muséologie et pour l'analyse biomécanique.Des analyses comparatives d’os de Néandertalien et d’humains modernes (bassin, fémur, côtes) en utilisant diverses populations de référence de Belgique ont également été menées. Ces études ont été réalisées en vue de comprendre la morphologie néandertalienne, pour aider à la reconstruction du squelette Spy II et à l'analyse biomécanique. Une étude sur la détermination du sexe à partir des pelvis a montré qu'il n'y avait pas de différence entre les mesures linéaires physiques et les mesures virtuelles, ce qui était une validation importante.Le logiciel musculosquelettique lhpFusionBox, développé à l'ULB, a été utilisé pour reconstruire le squelette. Un nouveau procédé de mise à l'échelle validé a été utilisé pour mettre à l'échelle le bassin de Kebara 2 aux dimensions du fémur de Spy II (comme Spy II ne possède qu’un petit fragment de sacrum) via le fémur et le bassin de Neandertal 1. La reconstruction d'un squelette complet de Néandertalien a apporté de nouvelles connaissances sur cette espèce dans différents domaines. Elle a permis la validation des reconstructions individuelles des os, de comparer les os longs reconstruits avec d'autres proportions des membres de Néandertaliens, de faire une estimation de stature, et de reconsidérer les attributions antérieures d'os à Spy II. La forme thoracique des Néandertaliens a déjà fait l'objet de nombreux débats. Cette reconstruction de Spy II, creé avec l'aide des experts utilisant les restes de Kebara 2, montre deux formes de reconstruction differentes, et indique les difficultés de la reconstruction thoracique des fossiles. Le squelette virtuel complet a été imprimé en 3D et utilisé par l’IRSNB et d'autres musées en Europe comme une référence de squelette néandertalien. Ce squelette a également été utilisé comme base pour les reconstructions artistiques hyper-réalistes de Néandertaliens, basées sur des données scientifiques, par les artistes Kennis et sont présentés dans les musées du monde entier. La reconstruction d'un membre inférieur complet a également permis des études biomécaniques. Ces dernières ont étudié la fusion du mouvement d'un homme moderne actuel avec des os néandertaliens. On ne peut pas se prononcer si le Néandertalien marchait ou s’accroupissait de manière similaire aux hommes modernes, mais on peut affirmer que leur morphologie osseuse leur permettait de marcher ou de s’accroupir de cette façon. Tous les bras de levier des principaux muscles de la hanche et du genou ont été analysés et il a été démontré que les Néandertaliens avaient les bras de levier plus grand que le modèle homme moderne signifiant Néandertaliens auraient eu un avantage mécanique important. Cette études démontre que des aspects de la morphologie postcrânienne néandertalienne soient différents, bien que certains d’entre eux soient plus semblables aux humains modernes qu'on ne le pensait.
