Uterus Transplantation
2018
Uterus transplantation (UTx) has been successfully introduced as a treatment option for women with absolute uterine factor infertility (AUFI). AUFI representing approximately 3% to 5% of the female general population is linked to either congenital uterine agenesis (Mayer-Rokitansky-Küster-Hauser syndrome), major congenital uterine malformation (hypoplastic uterus, fraction of bicornuate/unicornuate uterus), a surgically absent uterus, or an acquired condition (intrauterine adhesions, leiomyoma) linked to uterine malfunction that causes implantation failure or defect placentation. The world's first clinical uterus transplant was performed in 2000. However, a hysterectomy became necessary sho…
Hornhaut-Schlüsselbefunde im Kindesalter als Hinweis für therapierbare systemische Stoffwechselerkrankungen
2013
Es gibt eine Reihe von systemischen lysosomalen Stoffwechselerkrankungen, bei denen bereits im Kindesalter krankheitsspezifische Hornhauttrubungen zu beobachten sind. Unter Lysosomen verstehen wir winzige Zellorganellen, die vom Golgi-Apparat gebildet werden. Sie enthalten verschiedene hydrolytische Enzyme und Phosphatasen, womit Fremdstoffe oder korpereigene Stoffe verdaut werden konnen. Die richtige Einordnung der Hornhautveranderung durch den Augenarzt an der Spaltlampe kann zur richtigen Diagnose der jeweiligen systemischen Stoffwechselerkrankung fuhren. Eine moglichst fruhe Diagnosestellung ist aktuell besonders bedeutend, da heute einem Grosteil der Patienten mit einer Speicherkrankhe…
Land Snails as a Valuable Source of Fatty Acids: A Multivariate Statistical Approach
2019
The fatty acid (FA) profile of wild Theba pisana, Cornu aspersum, and Eobania vermiculata land snail samples, collected in Sicily (Southern Italy), before and after heat treatment at +100 °C were examined by gas chromatography with a flame ionization detector (GC-FID). The results show a higher content of polyunsaturated fatty acids (PUFAs) in all of the examined raw snails samples, representing up to 48.10% of the total fatty acids contents, followed by monounsaturated fatty acids (MUFAs). The thermal processing of the snail samples examined determined an overall reduction of PUFA levels (8.13%, 7.75%, and 4.62% for T. pisana, C. aspersum and E. vermiculata samples, respectively) and a spe…
The discovery of stapes
2013
Giovanni Filippo Ingrassia revisited and redefined some of Galeno's reports, and was recognized as one of the leading Italian Physicians of the 16th century. Ingrassia principally studied the skull, and gave very important contributions to otorhinolaryngology, including the discovery of the stapes. He also isolated the inferior nasal concha from the maxillary bone, described the frontal sinus, the pterygopalatine fossa and several foramina of the skull. Ingrassia firstly attributed a sensorial function to the middle ear bones, which he called fifth particular function. He also added some details to the description of the VIII cranial nerve, which introduces the concept of bone conducting so…
Curial e Güelfa y la prosa corta alegórica: Los Triunfos de Petrarca en la narrativa en catalán del XV
2013
Resumen: Los Triunfos de Petrarca gozaron de una amplia difusion en Europa, influyendo no solo en la literatura. En el presente articilo tratamos de ofrecer una vision de como la obra del italiano se dejo sentir en la Peninsula Iberica y, especialmente, en la Corona de Aragon. En este sentido, es remarcable la inspiracion que supuso el Triunfo del Amor , para el autor anonimo del Curial e Guelfa , aunque tambien se pueden encontrar rastros en otras obras. Palabras clave: Curial e Guelfa ; Petrarca; Triunfos ; tradicion literaria; humanismo; Corona de Aragon Abstract: The Trionfi of Petrarch enjoyed a wide circulation in Europe, influencing not only in literature. In this article we try to o…
Histological and ultrastructural study of corneal tunnel incisions using diamond and steel keratomes
1998
Abstract Purpose: To study the morphology of corneal tunnel incisions using diamond and steel keratomes. Setting: Department of Ophthalmology, University of Giessen, Germany. Methods: Corneal tunnel incisions were performed in six human cadaver eyes using three types of diamond keratomes and a steel keratome. The incision profile and morphology were evaluated and compared using light and scanning electron microscopy. Results: The steel keratome caused more disruption of corneal stromal tissue, while the diamond keratomes produced a more regular, smoother incision. The dissecting incision resulted in a smoother surface of cut stromal tissue than the stab incision. Conclusions: The high quali…
Predatory habits of the grasshopper-hunting waspStizus continuus(Hymenoptera: Crabronidae): diet preference, predator–prey size relationships and for…
2009
In a coastal salt-marsh of Spain, the digger wasp Stizus continuus primarily hunted for grasshoppers of the genus Heteracris, revealing (at least in the period of the study and in this area) this wasp to be almost monophagous. In contrast, grasshoppers of the genus Acrotylus were ignored by the wasps in spite of their high abundance in the environment. We hypothesize that this bias occurred because Acrotylus is found more often on the soil and on grasses, while Heteracris is nearly only found on Sarcocornia bushes, which probably represent the habitat mostly exploited by the wasps for hunting. The greater variance in size of the prey collected by larger females produced weak wasp–prey size …
Tratamiento de las ectasias corneales asociadas a LASIK con anillos intraestromales
2022
INTRODUCCIÓN: La ectasia corneal es una de sus complicaciones más graves de la cirugía LASIK. Está asociada a un adelgazamiento y un progresivo incurvamiento corneal y los anillos intracorneales (ICRS) se han propuesto como opción terapéutica debido a que inducen un aplanamiento. OBJETIVO: Evaluar los cambios producidos por los ICRS en pacientes diagnosticados de ectasias secundarias a LASIK. MATERIAL Y MÉTODOS: Es un estudio retrospectivo donde se incluyeron 26 ojos con ectasia post-LASIK los cuales fueron tratados con ICRS tipo Ferrara (AJL, Vitoria). Se les realizó un examen refractivo (agudeza visual (AV) y la refracción subjetiva). Mediante Pentacam®HR (Oculus: OtikgerateGmbH, Wetzlar,…
Inter-observer variability of central corneal thickness measurements using non-contact specular microscopy after laser in situ keratomileusis.
2003
BACKGROUND The aim of this study was to investigate the inter-observer variability of central corneal thickness measurements carried out with a non-contact specular microscope in patients who had undergone myopic laser in situ keratomileusis. METHODS Twenty-six eyes of 26 subjects who had undergone myopic laser in situ keratomileusis were studied with the Topcon SP-2000P non-contact specular microscope (Topcon Corp, Tokyo, Japan). The mean of three consecutive measurements of the central corneal thickness was recorded by two investigators prior to and one month after myopic laser in situ keratomileusis. Results obtained by each of the two physicians were compared. RESULTS Prior to surgery t…
