The problem of this study was the analysis of the pectoralis major during six antigravity exercises using electromyographc techniques. Thirty male subjects were used for the investigation from physical education classes at North Texas State University during the spring of 1976.

Die vorliegende Arbeit beschäftigt sich mit der Rolle der gestielten Lappen, am Beispiel des Acromiopectoral- und Pectoralis-Major-Lappens, in der modernen Mund-, Kiefer-, Gesichtschirurgie in einer Ära, in der mikrochirurgisch revaskularisierten, freien Transplantaten meist der Vorzug gegeben wird. Insbesondere wird auf die Einheilung und Resensibilisierung des Acromiopectoral- und Pectoralis-Major-Lappens in der Empfängerregion des Kopf-/Halsbereiches eingegangen. Es wurde die Lebensqualität der Patienten anhand von verschiedenen Parametern wie Nahrungsaufnahme, Sprachvermögen, Beschwerden und Ästhetik beurteilt. Des Weiteren wurde die objektive und subjektive Morbidität der Spenderregion untersucht. Es wurde geprüft, inwieweit die Entnahme der Lappen die Funktion, die Sensibilität und die Ästhetik des Schulter- und Brustbereiches beeinflussen. Anhand einer retrospektiven Datenauswertung von 30 Patienten werden die Unterschiede in den Indikationsbereichen, Komplikationsraten und Einheilraten der beiden Lappen im Zeitraum von 2000 bis 2010 aufgezeigt. / The present work deals with pedicled flaps using the example of an acromiopectoral and a pectoralis major flap, in an era in Oral and Maxillofacial surgery where preference is given to microsurgical free grafts. In particular, this work deals with the healing and resensitization of acromiopectoral and pectoralis major flaps in the recipient region of the head / neck area. The patient`s quality of life was assessed on the basis of various parameters such as food intake, power of speech, discomfort and aesthetic outcome. In addition, the objective and subjective morbidity of the donor region was examined and to what extent the removal of the transplant area affected the function, the sensitivity and the aesthetics of the shoulder and chest area. In a retrospective data analysis of 30 patients, the differences in the fields of indication, complication rates and rates of flap loss are demonstrated.

L’altération de l’environnement périnatal peut impacter à long terme l’expression des gènes notamment par le biais de modifications épigénétiques. Une stratégie pour accroitre la thermotolérance des poulets de chair, sensibles à la chaleur en fin d’élevage (J35) est la thermo-manipulation embryonnaire (TM). Lors d’un coup de chaleur à J35, les modifications d’expression de gènes observées chez les poulets TM pourraient être liées à une altération de l’épigénome induite lors de l’embryogenèse et persistante au cours du développement. Cette thèse s’intéresse à deux modifications post-traductionnelles des histones (MPTH) décrites pour être modulées par des variations thermiques : H3K27Me3 et H3K4Me3. Afin d’étudier ces MPTH sans a priori à J35, nous avons mis au point les techniques d’immunoprécipitation de la chromatine suivie de séquençage à haut débit dans deux tissus : l’hypothalamus et le muscle. Nos travaux montrent que le traitement semble impacter principalement l’épigénome de l’hypothalamus, en particulier au niveau de la marque H3K4me3, en modulant des voies liées à la morphogenèse et la réponse hormonale. / Perinatal environment changes may alter gene expression throughout life via epigenetic modifications. A strategy to improve thermal tolerance of heat-sensitive chickens is a thermalmanipulation during embryogenesis (TM). During a heat challenge at the end of the rearing period (D35), modifications of gene expression have been reported in thermally-manipulated chickens. These alterations could be linked to epigenetic modifications induced during the TM that persist throughout life. This work focused on two histone post-translational modifications (HPTM): H3K27me3 and H3K4me3. We adjusted two methods of chromatin immunoprecipitation to conduct a whole genome study of these HPTM at D35, in the hypothalamus and skeletal muscle. We demonstrated that the TM has a major impact in the hypothalamus, especially on H3K4me3. These alterations seem to modulate the hypothalamic morphogenesis and its response to hormones, therefore possibly contributing to better adaptive capacities of TM chickens.

Summary: Title: Kinesiologic analysis of function of selected upper limb muscles after female breast augmentation Objectives: The aim of this research is to analyze the functionality and scope of involvement of the injured muscles due to plastic surgical augmentation procedure at pre-selected physical activities before and after surgery a few months later (specifically, three months - the time the patient left the recovery) using a noninvasive surface electromyography (EMG). Methods: A Case Study measuring method of noninvasive surface electromyography in combination with the method of temporal phase shifts involved in the activation of muscle movement, accompanied by a support method of integrated EMG. Results: There differences have been observed in the timing of individual muscles measured during performing selected testing exercises before and after completion of the augmentation plastic surgery operatios. Furthermore, the possibility of the loss of muscle strength has been detected by some measured muscles and this has the potential to take over functions of damaged muscles. Key words: plastic surgery, female breast augmentation, surface electromyography, upper limb muscles, musculus pectoralis major
