INTRODUCTION: To date there has been no study reflecting the perceptions of first-year medical students on Eduard Pernkopf's atlas, particularly during their study of gross anatomy and prior to coursework in medical ethics. We present a discussion of Pernkopf's Atlas: Topographical Anatomy of Man from the perspective of U.S. medical students, and sought to determine whether medical students view Pernkopf's Topographical Anatomy of Man as a resource of greater accuracy, detail, and potential educational utility as compared to Netter's Atlas of Human Anatomy...

Tissue engineering offers promising perspectives in the therapy of osteoarthritis. In the context of cell-based therapy, chondrogenic progenitor cells (CPCs) may be used to regenerate defects in cartilage tissue. An in-depth characterization of the secretome of CPCs is a prerequisite to this approach. In this study, a method was developed for the qualitative and quantitative analysis of the secretome of undifferentiated and differentiated CPCs. Secreted proteins from cells grown in two-dimensional as well as three-dimensional alginate cultures were extracted and analyzed by liquid chromatography/tandem mass spectrometry (LC-MS/MS)...

Joost Brandsma, Anthony D Postle
The pathways and mechanisms that regulate pulmonary surfactant synthesis, processing, secretion and catabolism have been extensively characterised using classical biochemical and analytical approaches. These have constructed a model, largely in experimental animals, for surfactant phospholipid metabolism in the alveolar epithelial cell whereby phospholipid synthesised on the endoplasmic reticulum is selectively transported to lamellar body storage vesicles, where it is subsequently processed before secretion into the alveolus...

This study was intended to confirm whether simultaneous examination of surface and volume models contributes to learning of hand structures. Outlines of the skin, muscles, and bones of the right hand were traced in sectioned images of a male cadaver to create surface models of the structures. After the outlines were filled with selected colors, the color-filled sectioned images were stacked to produce a volume model of the hand, from which the skin was gradually peeled. The surface models provided locational orientation of the hand structures such as extrinsic and intrinsic hand muscles, while the peeled volume model revealed the depth of the individual hand structures...

INTRODUCTION: Pathological formation of blood vessels plays a key role in the growth and metastasis of tumors and also in several serious ophthalmological diseases such as wet age-related macular degeneration (AMD) or diabetic retinopathy. In AMD treatment, aflibercept (tradename EYLEA(®)) is used to deactivate the underlying pathological neovascularisation. Aflibercept is a recombinant fusion protein which binds to vascular endothelial growth factor (VEGF) receptors, thereby inhibiting VEGF pathway activation...

Hassall's corpuscles are the most prominent structures in the human thymus. However, relatively few analyses have been performed to determine their function and cellular origins during development. In this study, we evaluated the cellular microenvironment of human thymic Hassall's corpuscles using histochemistry, immunohistochemistry, and transmission electron microscopy. We examined 95 human thymic tissue samples, which were perioperatively obtained from children undergoing cardiac surgery. To characterize the complex cellular microenvironment of human thymic corpuscles, we used a panel of 14 different antibodies to identify discrete cell types...

Recent analyses have suggested that the size and proportions of the precuneus are remarkably variable among adult humans, representing a major source of geometrical difference in midsagittal brain morphology. The same area also represents the main midsagittal brain difference between humans and chimpanzees, being more expanded in our species. Enlargement of the upper parietal surface is a specific feature of Homo sapiens, when compared with other fossil hominids, suggesting the involvement of these cortical areas in recent modern human evolution...

INTRODUCTION: The aim of this work is to point out the intraspinal extradural anatomical variations of nerve roots and their possible participation in radiculopathy. METHODS: The anatomical study was performed in 33 cadavers at a mean age of 46.5 and up to 24h from death. All extradural anastomoses between nerve roots were excised and examined histologically for the presence or absence of nervous tissue. The type of the plexus was defined by subtracting from the root C2...

Isotretinoin broad effectiveness is limited by its detrimental effect on the Meibomian glands. Androgens have been reported to regulate the Meibomian gland function. Dehydroepiandrosterone (DHEA) is an androgen precursor considered as an efficient and physiological anti-ageing skin agent. This study aimed to investigate the role of the topical DHEA in ameliorating Meibomian gland dysfunction caused by isotretinoin employing different histological and immunohistochemical techniques. Twenty-four adult male albino rats were divided into four equal groups; control group, DHEA-treated group (1% twice daily for 3 months), isotretinoin-treated group (0...

Sabine Hildebrandt, Gabriele Czarnowski
Despite intensified research efforts on the history of anatomy during National Socialism (NS), many aspects of this story still need further investigation. This study explores the life, work and politics of Alfred Pischinger, Chairman of the Institute for Embryology and Histology in Graz from 1936 to 1945, and in Vienna from 1958 to 1970, and is an addition to previous reports on careers in anatomy continuing through the Third Reich to the postwar period. Pischinger was an illegal NSDAP member in Austria, joined the SA in 1938, served as expert in racial hygiene, and as judge on the Genetic Health High Court of Graz...

The present study was performed to test the therapeutic effects of Survanta (an exogenous surfactant) on a Wistar rat model of emphysema. Thirty-five adult male Wistar rats were divided randomly into the following groups; control subgroups Ia&b (n=14); emphysematous model subgroups IIa,b&c (n=21) exposed to cigarette smoke (CS), received phosphate buffer solution (PBS) and Survanta respectively. The levels of serum myeloperoxidase (MPO), lung tissue lactate dehydrogenase (LDH), alkaline phosphatase (ALP) as well as antioxidants: catalase (CAT), superoxide dismutase (SOD) and oxidative stress: malondialdehyde (MDA) markers were measured...

Pulmonary surfactant, a mixture of lipids and proteins at the air-liquid interface of alveoli, prevents the lungs from collapsing due to surface tension. One constituent is surfactant-associated protein-D (SP-D), a protein involved in surfactant homeostasis and innate immunity. Mice deficient in SP-D (SP-D (-/-)) has been described as developing a characteristic phenotype which affects the surfactant system (including changes in the intra-cellular and intra-alveolar surfactant pool, alveolar epithelial type II cells and alveolar macrophages), lung architecture and its inflammatory state (development of an emphysema-like pathology, inflammatory cell infiltration)...

Outflow tract development of the heart is complex. The presence, differential growth and interactions of the various tissues through space and time contribute to the final development of the tract. This paper presents a novel interpretation of observations of outflow tract development, in particular of the aortic and pulmonary semilunar valves in embryos from the Shaner Collection at the University of Alberta. Three-dimensional reconstructions assist in the visualization of the spatial relationships of the developing valve tissues...

Pulmonary surfactant is broadly known to keep the lung dry, clean and open by lowering the surface tension of the fluid-film that lines the alveoli. The surfactant's protein component, the so called surfactant proteins (SPs), make up a multifunctional protein family. In addition to the four "classical" surfactant proteins (SP-A, SP-B, SP-C and SP-D), which possess immunologic as well as surfactant regulatory properties, two novel putative surfactant proteins (SFTA2 and SFTA3) have recently been described. Neither of them shows sequential nor structural similarity with the already known surfactant proteins...

The human orbital muscle (OM) is not readily accessible during ordinary anatomical teaching because of insufficient time and difficulties encountered in the preparation. Accordingly, its few anatomical descriptions are supported only by drawings, but not by photographs. The aim of this study was to present OM in dissected anatomic specimens in more detail. Following microscope-assisted dissection, its location, syntopy and morphology were analyzed in 88 orbits of 51 cadavers. Together with the periorbital connective tissue OM filled the infraorbital fissure (IOF) and extended back to the cavernous sinus...
