Article: Changes of laryngeal parameters during intrauterine life.
[show abstract] [hide abstract]
ABSTRACT: Increased care of fetal and neonatal airways has led to advances in neonatal medicine. The early diagnosis and treatment of respiratory diseases require a detailed knowledge of fetal airway anatomy and development. The aim of this study was to determine the anatomical development of the thyroid and cricoid cartilages and their structural variability during fetal life. The study was performed on the thyroid and cricoid cartilages of 55 human fetal larynges of both sexes, between the ages of 13 and 27 weeks of intrauterine life. Numerous measurements of the thyroid and cricoid cartilages were performed. Correlations between the obtained results were calculated in relation to the crown-rump (C-R) length of human fetuses and to sex. The structural variability of the thyroid and cricoid cartilages of human male and female fetuses in subsequent weeks of intrauterine life was observed. In both genders a correlation between laryngeal size and fetal crown-rump length, regardless of sex, was found. The thyroid cartilage presents a sexual dimorphism. The results of this study can be useful in the analysis of prenatal examinations, and in planning the treatment of airway emergencies.European journal of medical research 11/2010; 15 Suppl 2:41-5. · 1.13 Impact Factor -
Article: Analysis of the correlation between aortic diameter, heart size, and type of coronary circulation.
[show abstract] [hide abstract]
ABSTRACT: The objective of this study was to analyse the correlation between aortic diameter, heart size, and type of coronary circulation. The study was carried out on 102 human hearts (59 male and 43 female). Casts of the vascular system of each heart were prepared using epoxide resins. The hearts were measured for their size and aorta diameter, and classified to a coronary circulation type. The examination of materials indicated no significant correlation between aortic diameter and sex or coronary circulation type. However, a statistically significant correlation between aortic diameter and heart volume index was found.Folia morphologica 02/2010; 69(1):30-4. · 0.52 Impact Factor -
Article: Analysis of the influence of heart size and gender on coronary circulation type.
[show abstract] [hide abstract]
ABSTRACT: Currently, there are many types of classification of coronary circulation. The first type was introduced in 1904 by Banchi. Hettler provides very detailed criteria for the type classification based on the course of the anterior and posterior interventricular branches. Hettler defined the following types: left coronary artery dominance, right coronary artery dominance, and co-dominant. The objective of this study was to analyse coronary circulation types in the studied material and their correlation with heart size and gender. The study was carried out on 102 human hearts (59 male and 43 female). True casts of coronary vessels were obtained using epoxide resins. The prepared specimens were measured for heart dimensions and evaluated for coronary circulation type. The majority of the specimens were classified as the co-dominant type, followed by the right coronary artery dominant type. The left-dominant coronary artery type represented the lowest number of heart specimens. No statistically significant correlation between the type of coronary circulation and heart size or gender was found. The coronary circulation type is not correlated with heart size or with gender. This confirms that it is a hereditary trait.Folia morphologica 02/2010; 69(1):35-41. · 0.52 Impact Factor -
Article: The fluctuating asymmetry of medieval and modern human skulls.
[show abstract] [hide abstract]
ABSTRACT: The analysis of fluctuating asymmetry (FA) allows for estimating the influence of stress factors on human development and allows to evaluate resistance to stress. FA is often used as a marker of prenatal stress. The aim of this work is to estimate the symmetry of skulls from selected historic human populations and to analyse changes in their morphology which have taken place over centuries. The studied material consisted of two skull samples - a modern sample containing 82 skulls and a medieval sample of 77 skulls from Gródek on the Bug River. Radiographs were taken in postero-anterior (P-A) and base projections. Images were scanned and calibrated by means of MicroStation 95 Academic Edition software. Measurements of the skull images were used to estimate FA. All data were analysed statistically. The skulls in both samples showed asymmetry. The levels of FA varied in different skull regions. A high level of FA in the calvaria and a low asymmetry for the facial part of skull is characteristic of modern skulls. In medieval skulls these relations are inverted. The higher value of FA in modern skulls is an evidence of a higher level of developmental stress in the modern population as well as of its lesser abilities to resist stress.HOMO - Journal of Comparative Human Biology 02/2007; 58(2):159-72. · 0.54 Impact Factor -

Często używana jest jako wskaźnik stresu prenatalnego. Celem pracy była ocena symetrii czaszek wybranych populacji dziejowych i analiza zmian zachodzących w ich budowie na przestrzeni wieków.Materiał badawczy stanowiły dwie próby czaszek , współczesna złożona z 82 czaszek i średniowieczna z 77 czaszek z Gródka nad Bugiem. Wykonano zdjęcia radiologiczne w rzucie P-A i na podstawę. Zdjęcia zostały zeskanowane, a następnie poddane procesowi kalibracji w oprogramowaniu MicroStation 95 Academic Edition. Dane zostały poddane analizie statystycznej.Na podstawie zdjętych pomiarów oszacowano asymetrię fluktuacyjną. Stwierdzono występowanie asymetrii w obu badanych próbach. Wartość asymetrii fluktuacyjnej w różnych okolicach czaszki nie jest jednakowa. Czaszki współczesne cechują wysokie wartości asymetrii fluktuacyjnej w obrębie sklepienia czaszki i niskie w obrębię twarzoczaszki. W czaszkach średniowiecznych panują stosunki odwrotne. Wyższy poziom wartości wskaźników asymetrii fluktuacyjnej w czaszkach współczesnych świadczy o większym nasileniu działania stresu rozwojowego w tej populacji i o jej słabszych możliwościach kompensacyjnych.HOMO - Journal of Comparative Human Biology.
