Abstract:
ZusammenfassungBildgebungsmethoden wie die MR-Morphometrie und die MR-Spektroskopie (MRS) werden seit längerem zur Untersuchung regionaler Hirnvolumen- bzw. -metabolismusveränderungen in der Schizophrenieforschung eingesetzt. Ein möglicher differenzieller Effekt von traditionellen Neuroleptika im Vergleich zu den atypischen Antipsychotika blieb dabei lange unberücksichtigt. In Übereinstimmung mit funktionellen Bildgebungsdaten zeigen nun neuere Daten, dass die so genannten atypischen Antipsychotika, verglichen mit traditionellen Neuroleptika, einen geringeren Einfluss auf die Basalganglienstruktur sowie einen eher günstigen Effekt auf die mit MRS gemessene neuronale Integrität zu haben scheinen. Das gilt ebenso für die Volumenveränderungen in fronto-temporalen Arealen sowie im anterioren Zingulum, welche mit kognitiven Funktionen korrelieren. Diese Befunde bedürfen jedoch vorsichtiger Interpretation, da die verbesserten Bildgebungsmöglichkeiten auch an zusätzliche methodologische Überlegungen geknüpft sind wie das Kontrollieren von Stör- und Moderatorvariablen, die exakte Designspezifikation, Strategien des Post-Processings, physiologische Variation des lebenden Gehirns, messbare Perfusionseffekte und Limitierungen durch die Hardware.

Abstract:
Abstract Background : Anthropologists are often faced with the task of assigning sex to remains that are incomplete, fragmented or damaged as may result from incidents such as mass disasters, airplane crashes, fire, explosions or physical violence. The size of foramen magnum does not change after puberty, not related to age then after. It is this part of the cranial base which can withstand fire explosions as the area is covered by large amount of soft tissue. Hence the foramen magnum was considered for studying the sexual differences in skull. Aims : To analyse the morphology and morphometry of foramen magnum, and the impact of these variables on sex determination of skull. Materials and Methods : 68 male and 68 female adult dry skulls were used for the study. The shapes of foramen magnum were studied. Results : In total, oval was the most common shape comprising of 61.76%, 16.17% arrow head, 11.76% irregular and 10.29% round. The sagittal diameter was 33.0 [28-40] mm in males and 33.0 [28-43] in females and transverse diameters of foramen magnum were 27[21-31] in males and 26.0[23-33]mm in females. Area of foramen magnum was calculated using Radinsky and Teixeria formulae and foramen magnum index was calculated. Mean, standard deviation and median [where ever required] were calculated. Student t test and Mann Whitney U test/ T test were applied. We did not find significant difference between male and female values. Conclusion : Our study did not demonstrate statistically significant difference in expression of sexual differences in the foramen magnum. However if detailed analysis is done with greater sample size by discriminant function analysis, it may prove useful in predicting sex in severely fragmented cranial bases.

Abstract:
Morphometric characters of fishes are measurable or metric characters. Morphometrics is a more or less interwoven set of large statistical procedures to analyze variability in the size and shape of organisms. Morphometrics and phylogenetics of a species are combined to utilize existing phylogeny which addresses hypotheses of shape change through evolutionary time. Morphometric differences among stocks of a species are recognized as important to evaluate population structure and form a basis to identify stocks. Advancements in morphometrics used powerful tools for testing and displaying differences in shape, isolated shape from size variation and identifying stocks of species with unique morphological characteristics enabling better management of the species. Traditional or standard morphometry has been improvised from time to time with advanced methods by technological advancements like geometric morphometrics, image analysis, principal component analysis, truss network analysis and multivariate analysis as well as many more to update knowledge and get more accurate information. These advanced methods have strengthened earlier technologies to improve upgrade fishery research throughout the globe. Doi: 10.28991/HEF-2020-01-03-05 Full Text: PDF

Für die beiden letztgenannten Arten liegen bisher keine karyologischen Daten vor. Die Karyotypen der drei untersuchten Arten mit n=5 und 2n=10 bestehen aus metacentrischen Chromosomen. Die Verteilung des konstitutiven Chromatins scheint in der Gattung Nasonia Ashmead, 1904 ebenfalls sehr einheitlich zu sein. Demgegenüber ergab die Morphometrie der Chromosomen statistisch signifikante Unterschiede zwischen den drei Arten. Die vorliegenden Daten entsprechen der Abfolge der Artenspaltungen im Nasonia-Komplex, die auf der Basis molekulargenetischer Untersuchungen festgestellt wurde.

AbstractCanonical discriminant analysis of four morphometric characters of juveniles and restriction enzymes analysis of ribosomal DNA sequences were used to distinguish Heterodera arenaria, H. aucklandica, H. avenae, H. filipjevi, H. hordecalis, H. iri, H. latipons, H. litoralis, H. schachtii and an undescribed species from grasslands. The results of unweighted pair group cluster analysis showed that H. avenae populations formed three groups and H. filipjevi two groups at the 80% level of similarity. Intraspecific polymorphism was revealed by rDNA-RFLP studies and two types of ITS regions within H. avenae populations can be distinguished. The pattern of restriction bands obtained with BsuRI, PstI and TaqI clearly distinguished populations of H. filipjevi from other species of the H. avenae group. Further enzymes and their combinations distinguished the other species. There are no enzymes which differentiate European populations of H. avenae from H. arenaria. Morphometrics, restriction endonuclease cleavage maps of ITS regions and a dendrogram of putative phylogenetic relations of several cyst-forming nematode species are given.

Abstract:
Multivariate morphometry was used to investigate the distinctness and interrelationships of six stocks of the common carp (Cyprinus carpio). A "size" component was clearly identified by multiple group principal component analysis. Canonical variate analysis computed only on the "shape" components showed that the stocks were morphometrically distinct and that the phenetic relationships based on allozymic and morphometric data are highly congruent. We therefore suggest that multivariate morphometrics could represent an appropriate and convenient tool to detect variation between strains in carp culture.

Abstract:
Morphometry is introduced as quantitative approach to seek information concerning variations and changes in the forms of organisms that described the relationship between the human body and disease. Scientists of all civilization, who existed until today, examined the human body using anthropometric methods. For these reasons, anthropometric data are used in many contexts to screen for or monitor disease. Anthropometry, a branch of morphometry, is the study of the size and shape of the components of biological forms and their variations in populations. Morphometrics can also be defined as the quantitative analysis of biological forms. The field has developed rapidly over the last two decades to the extent that we now distinguish between traditional morphometrics and the more recent geometric morphometrics. Advances in imaging technology have resulted in the protection of a greater amount of morphological information and have permitted the analysis of this information. The oldest and most commonly used of these methods is radiography. With developments in this area, CT and MRI have also been started to be used in screening of the internal organs. Morphometric measurements that are used in medicine, are widely used in the diagnosis and the follow-up and the treatment of the disease, today. In addition, in cosmetology use of these new measurements is increasing every day.

Abstract. The effect of disruptive selection for body conformation on body weight and length, tail length, and femur weight and length at different stages of development (21, 42, 63, and 120 days of age) was analysed in four mouse lines of the CBi stock selected for (CBi+, CBi-) and against (CBi/L, CBi/C) the phenotypic correlation between body weight and tail length, and die unselected control line CBi. As expected, body weight and tail length distributed according to the selection criteria; rrunk length (whole body length minus tail length) behaved as body welght at all ages. CBi/L had the highest femoral length (p < 0.01), and CBi/C attained the highest femoral weight (p < 0.01). CBi+ and CBi-, harmonically large or small, differed between them and from the control line in both variables (p < 0.001). These findings further corroborate the proposal that bone mass is markedly affected by the skeleton function as support of soft tissues. The allometric analysis ofthe regression of femur weight on femur length suggests that, in this model, a) the demand posed by the selective pressure forced each genotype to find a unique Solution, b) this response is sex-dependent, and c) genetic determination ofthe parameters involved in this allometric relationship is, at least, partially independent.

Abstract:
Eine taxonomische Synopsis der 6 paläarktischen Arten der Myrmica-schencki-Gruppe, basierend auf der Arbeiter-Morphologie, wird vorgestellt. Alle Arten können mittels Morphometrie und Strukturmerkmalen deutlich unterschieden werden. Myrmica pelops sp. n., ein Endemit des südlichen Griechenland, wird erstmals beschrieben.

ZusammenfassungDie Magnetresonanztomographie(MRT)-basierte Volumetrie bietet in vivo Verfahren für die Detektion der Atrophie in den Anfangsstadien der Alzheimer-Krankheit (AD) und stellt potenziell eine geeignete Methode für die klinische Früherkennung und Untersuchung des Krankheitsverlaufs dar. Das Gros der volumetrischen Studien berichtete signifikante Volumenverluste bereits in prädemenziellen Stadien der AD. Die manuelle Volumetrie ist allerdings durch einen hohen Zeitaufwand und die Festlegung auf a priori ausgewählte Gehirnregionen hinsichtlich der klinischen Relevanz limitiert. In den letzten Jahren ist eine Vielzahl automatischer Verfahren zur Volumetrie einzelner Gehirnstrukturen und der Detektierung von Atrophiemustern im Gesamtgehirn entwickelt worden, die Gegenstand der vorliegenden Übersichtsarbeit sind. Ergebnisse semi-automatischer Hippokampus-Volumetrie konnten erfolgreich die Befunde manueller Volumetrie replizieren. Mittels Voxelbasierter Morphometrie und hochparametrischer Fluidregistrierung konnten krankheitsspezifische Atrophiemuster im Gesamthirn sichtbar gemacht werden. Die Bestimmung von Atrophiemustern ist besonders aus differenzialdiagnostischer Perspektive interessant, bedarf aber noch einer klinischen Validierung.

Abstract:
South American camelids were essential to the subsistence of pre-Hispanic Andean populations. In Northwestern Argentina (NOA), both wild and domesticated large camelid species—guanaco and llama—have been present in the archaeological record since the early Late Holocene. Differentiating between their remains is crucial for understanding the dietary contributions of wild and domesticated resources to these populations. Traditional morphometric methods, often used to distinguish camelid species by size, encounter challenges due to the overlapping body sizes of guanacos and llamas. This study, conducted between 2019 and 2024, analyzes a sample of first phalanges from guanacos and llamas at the Quebrada del Cementerio site (Quebrada de Humahuaca, Jujuy, Argentina) using two-dimensional geometric morphometrics techniques. The goal is to distinguish these camelid phalanges by shape, aiding in accurate taxonomic identification. The results were compared with previous size-based studies using traditional morphometric techniques, revealing a predominance of llamas over guanacos, consistent with prior osteometric assessments. However, traditional morphometry lacks precision in identifying intermediate-sized specimens, which may represent either large guanacos or small llamas. Geometric morphometrics, on the other hand, allows for a more precise taxonomic identification of these specimens, complementing traditional methods. This approach refines the representation frequencies of both species, showing a slightly lower percentage of llamas and a higher percentage of guanacos than previously estimated by osteometric analysis. The findings offer a more detailed view of the role these species played in the diets of human populations in Quebrada during the Late Holocene.

Abstract:
Geometric morphometrics is a tool capable of measuring the response of organisms to different environmental pressures. We tested the hypothesis that E. cordata wing morphometry, as an indicator of response to environmental pressure, it would vary depending on habitat changes, in the Atlantic Forest, Savanna and dry forest (Caatinga). For analysis of wing shape and size, 18 landmarks were digitized at the intersections of the wing veins 348 individuals. Except for the two populations sampled in Chapada Diamantina, the wing shape had significant statistical variations among the populations (p < 0.05). The wing size variation was also statistically significant among populations (p < 0.05). Although E. cordata is a species tolerant to different environments, the observed morphometric variability may be related to population adaptations to the conditions of each phytophysiognomy.

Abstract:
Morphometry is an effort to describe or measure the morphology of the body, or parts of it. It also provides quantitative data on the interactions of living organisms with their environment, external or internal. As a discipline, morphometrics has undergone significant developments in the last decade, making its implementation more visual and less laborious. Chagas disease vectors, often referred to by the common name of “kissing bugs”, belong to the subfamily Triatominae. Due to their apparent morphological plasticity, they have been the subject of numerous morphometric studies. Most of these have been applied taking into account the particularities of this group of vectors, such as domesticity (synanthropy), food preferences, dispersal ability, insecticide resistance, as well as some taxonomic issues. This brief review over nearly three decades is organized here according to the body organs considered by the authors.

Abstract:
Variations in shapes and morphometry of spleen is seen. Number and location of splenic notches show regional variation. This study is done to determine tools for sexual dimorphism of spleen. 72 spleen of known sex were used from cadavers used for 1st MBBS dissection. Shape, number and location of splenic notches were noted. Length, breadth, thickness and weight of spleen were calculated. Triangular shaped spleen was seen most commonly. Maximum 5 notches were seen on a spleen. Morphometric measurements showed regional variations and sexual dimorphism. We conclude that formation of splenic notches by incomplete fusion of various lobes has been mentioned in earlier embryological studies but new hypothesis suggests that these notches can be considered developmental variations. A wide variation in shapes and morphometrics of spleen is seen. They can be used as tools of sexual dimorphism.

Abstract:
CONTEXT: Differential diagnosis of hyperplastic vs adenomatous lesions is of crucial importance on the daily practice of colonoscopy. OBJECTIVES: This study aimed at quantifying digital morphometric characteristics of colonoscopic images obtained with magnification and chromoscopy of three different types of colonic lesions: hyperplastic, adenomas and carcinomas, and the normal mucosa surrounding the lesions. METHODS: A total of 2,177 consecutive colonoscopies were analyzed and 105 images were chosen for analysis, divided into 37 hyperplastic lesions, 42 adenomas and 26 carcinomas. Specific digital morphometry was used, to measure the diameter and area of the pits from hyperplastic lesions, adenomatous and carcinomatous lesions, always comparing them with the normal mucosa surrounding pits. RESULTS: Different morphometric measures were performed via image analysis software to measure the mean pit opening diameters and their respective area. The mean pit opening diameters and corresponding area measurements were statistically significant for all groups of lesions examined. CONCLUSIONS: The morphometric characteristics of colonoscopy images allowing the observer to compare differences between hyperplastic and adenomatous polyps and colorectal carcinoma lesions. Digital morphometric studies are feasible like the present study shows. This can help the colonoscopist in clinical decisions. A software with morphometric measures can apply and will permit the digital morphometric analysis. The data generated from the application of software, can provide valuable points in differentiation of various lesions, guiding the conduct clinical, already during the endoscopic procedure. Morphometric analysis is more an instance of decision to the colonoscopist and it has important value not for being subjective, but for being objective, since it generates digits of its measures. In these aspects, and among different characteristics, the measure of the area showed to be the most important measure in the differential aspect. Different lesions have different patterns of morphometric measures and theses patterns can be obtained from the study of the characteristics in databases. The endoscopic removal of adenomatous polyps (polypectomy), or a more detailed study of the neoplastic lesions for helping the decision if endoscopic removal (mucosectomy) or surgical resection, and a conservative position in hyperplastic lesions, are proceedings that morphometrics, with another parameters, can help to decide.

Abstract:
Background/Objectives: Irritable bowel syndrome (IBS) is a gut–brain disorder characterized by abdominal pain, altered bowel habits, and psychological distress. While brain–gut interactions are recognized in IBS pathophysiology, the relationship between brain morphometry, cognitive function, and clinical features remains poorly understood. The study aims to conduct the following: (i) to replicate previous univariate morphometric findings in IBS patients and conduct software comparisons; (ii) to investigate whether multivariate analysis of brain morphometric measures and cognitive performance can distinguish IBS patients from healthy controls (HCs), and evaluate the importance of structural and cognitive features in this discrimination. Methods: We studied 49 IBS patients and 29 HCs using structural brain magnetic resonance images (MRIs) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Brain morphometry was analyzed using FreeSurfer v6.0.1 and v7.4.1, with IBS severity assessed via the IBS-Severity Scoring System. We employed univariate, multivariate, and machine learning approaches with cross-validation. Results: The FreeSurfer version comparison revealed substantial variations in morphometric measurements, while morphometric measures alone showed limited discrimination between groups; combining morphometric and cognitive measures achieved 93% sensitivity in identifying IBS patients (22% specificity). The feature importance analysis highlighted the role of subcortical structures (the hippocampus, caudate, and putamen) and cognitive domains (recall and verbal skills) in group discrimination. Conclusions: Our comprehensive open-source framework suggests that combining brain morphometry and cognitive measures improves IBS-HC discrimination compared to morphometric measures alone. The importance of subcortical structures and specific cognitive domains supports complex brain–gut interaction in IBS, emphasizing the need for multimodal approaches and rigorous methodological considerations.

Abstract:
ZusammenfassungDie Lese-Rechtschreib-Störung (LRS) gilt als die häufigste aller Lernentwicklungsstörungen überhaupt. Etwa 5% der deutschen Bevölkerung leidet unter den psychischen und sozialen Folgen schwerwiegender umschriebener Probleme beim Erlernen des Lesens und Schreibens. LRS entsteht aus dem komplexen Zusammenspiel von genetischen Faktoren und Umweltfaktoren (z. B. sprachliche Lernvoraussetzungen im Elternhaus). In zahlreichen vorangegangenen Magnetresonanztomografie (MRT) Studien wurde zudem gezeigt, dass der linke gyrus fusiformis (FFG, sogenanntes „visuelles Wortformareal“) des Gehirns eine entscheidende Rolle für den Schriftspracherwerb spielt. Die hier vorgestellte Arbeit legt nahe, dass die kortikale Plastizität des FFG bei LRS durch das Tragen einer Risikovariante des Gens NRSN1 eingeschränkt sein könnte, dessen Proteine u. a. das Wachstum von Dendriten steuern. NRSN1 erwies sich als signifikant mit dem Volumen des linken FFG assoziiert, welches mithilfe von voxelbasierter Morphometrie (VBM) auf Grundlage von MRT Aufnahmen gemessen wurde. Anhand der durch genetische Assoziation bestimmten volumetrischen Profile von Kindern, die sich etwa 10 Monate vor Schuleintritt befanden, konnte die spätere Ausprägung einer LRS mit einer Klassifikationsgenauigkeit von 75% vorhergesagt werden. Diese Daten lassen hoffen LRS in Zukunft so früh feststellen zu können, dass betroffene Kinder in der Lage sind ihre Defizite vor der Einschulung mithilfe von Frühförderungsmaßnahmen zu kompensieren.

Biodiversitas 19: 1013-1020. The study concerning the morphometry of Sentani gudgeon (Oxyeleotris heterodon, Weber 1907) was done from August 2016 until April 2017 in Sentani Lake, Jayapura District, Papua Province, Indonesia. The objectives of the study were to find out the diversity of the fish using truss morphometry approach. A total 56 individual sampled from three sampling sites were characterized for their 26 truss morphometric characters. The result showed that there were differences on morphometric characters of Sentani gudgeon. The highest correlation value found in character B2 and D5, which represented the dorsal portion and the tail fin of the fish body respectively. All variables showed significant different between each location (the p-value <c0.05). The canonical diagram resulted of 26 truss morphometric characters illustrated three separated clusters which discriminated the three populations based on sampling sites. A genetic distance analysis among Sentani gudgeon indicated that the fish originated from Putali Village was morphologically closed to the fish population from Sosiri. The truss morphometry technique can be used to identify the diversity of Sentani gudgeon in Sentani Lake
