Magnetoelectric effects in superconductor/ferromagnet bilayers
2018
We demonstrate that the hybrid structures consisting of a superconducting layer with an adjacent spin-textured ferromagnet demonstrate the variety of equilibrium magnetoelectric effects originating from coupling between the conduction electron spin and superconducting current. By deriving and solving the generalized Usadel equation which takes into account the spin-filtering effect we find that a supercurrent generates spin polarization in the superconducting film which is non-coplanar with the local ferromagnetic moment. The inverse magnetoelectric effect in such structures is shown to result in the spontaneous phase difference across the magnetic topological defects such as a domain wall …
Flexural behaviour of calcarenite masonry walls reinforced with FRP sheets
2015
The use of fiber-reinforced polymers (FRP) for structural strengthening has become increasingly popular in recent years. Several applications of FRP have been proposed and applied, depending on the target of the technique, kind and/or material of the structural member. In particular, because of their great tensile strength, FRP materials are commonly used to enhance the out-of-plane behaviour of masonry walls, allowing to increase their strength, ductility and improving safety against overturning. For these reasons, FRP laminates are often applied in vulnerable ancient buildings in seismic areas to reinforce façades and walls with poor structural features. However, some issues arise when ad…

Angst als Textspur und Bildspur in Graphic Novels zum historischen Geschehen des 20. Jahrhunderts
2020
Neben vielen anderen Charakterisierungen, etwa ‚Jahrhundert der Diktatoren‘, ist für das 20. Jahrhundert wahrscheinlich auch die Formulierung ‚Jahrhundert der Angst‘ gerechtfertigt. Dieser Beitrag ist ein erster Versuch, die Darstellung von Angst in verbal-piktoralen Narrativen zu erschließen. Text- und Bildspuren zu Angst – politisch genutzte Techniken der Angsterzeugung einerseits und bis zu dauerhafter Traumatisierung gehende Angsterfahrung andererseits – sind in vielen Graphic Novels zur Geschichte des 20. Jahrhunderts ein wesentliches Deutungsangebot. Obwohl ästhetisch und intellektuell anspruchsvoll, somit ein Angebot zur Aufarbeitung von Geschichte, ist diese Fokussierung von Angst d…
Monoclonal antibody 3H8: A useful tool in the diagnosis of candidiasis
1999
In a previous series of experiments six mAbs were obtained against cell wall extracts of Candida albicans ATCC 26555. After several studies only one of them, designated 3H8, has been used to produce a commercial kit for the rapid diagnosis of candidiasis, Bichro-latex albicans (Fomouze Diagnostics). The present study involved the generation and characterization of this mAb as an immunoglobulin G1 which recognizes mannoproteins of high molecular mass present in the C. albicans cell wall. ELISA assays showed that the presence of the epitope recognized by mAb 3H8 was similar in both yeast and mycelial cell walls of C. albicans, in contrast to the epitope for mAb 1B12, which is mainly expressed…
Fab fragments from a monoclonal antibody against a germ tube mannoprotein block the yeast-to-mycelium transition in Candida albicans.
1990
Fab fragments prepared from the immunoglobulin G monoclonal antibody (MAb) 4C12, which reacts with a determinant expressed on the hyphal extension of germ tubes of Candida albicans, inhibited germ tube formation, but intact MAb 4C12 did not. Indirect immunofluorescence showed a punctate binding pattern on cells incubated with Fab fragments but a confluent binding on cells incubated with intact MAb 4C12.
Role of Hemodynamic Forces in Unruptured Intracranial Aneurysms: An Overview of a Complex Scenario.
2017
Background An understanding of the natural history of unruptured intracranial aneurysms (IAs) has always played a critical role in presurgical or endovascular planning, to avoid possibly fatal events. Size, shape, morphology, and location are known risk factors for rupture of an aneurysm, but morphologic parameters alone may not be sufficient to perform proper rupture risk stratification. Methods We performed a systematic PubMed search and focused on hemodynamics forces that may influence aneurysmal initiation, growth, and rupture. Results We included 223 studies describing several hemodynamic parameters related to aneurysm natural history. In these studies, different modalities of aneurysm…
Intramuscular Abdominal Wall Endometriosis, an Unusual Finding for General Surgeon
2021
Abstract Defined as the ectopic development of uterine tissue outside the uterine cavity, endometriosis is an increasingly common condition that can lead to various complications from chronic pain syndrome, infertility, obstruction due extrinsic compression to malignancy of endometriosis foci. Extrapelvic positioning of endometriosis is rare, diagnosis can be difficult both clinically and imaging, and treatment does not always ensure the absence of recurrences.
Unexpected finding of urachal remnant cyst. Tips for laparoscopic approach
2020
Highlights • Urachal cyst is a common anomaly related to the incomplete obliteration of the urachal lumen. • This condition, per se asymptomatic, is not without risk. • In symptomatic cases, the main approach is the laparoscopic excision.
Abdominal Tumor in a 14-Year-Old Adolescent: Imperforate Hymen, Resulting in Hematocolpos—A Case Report and Review of the Literature
2014
Background. Abdominal masses in female adolescents are uncommon. A rare cause of this condition is hematocolpos due to imperforate hymen.Case. We present a case of an unusually massive asymptomatic abdominal bulk in a 14-year-old female patient, who sought for medical advice after unusual abdominal pain lasting for few weeks. The patient was otherwise asymptomatic, apart from an unusual dramatic expansion of her abdominal wall during the last month. We describe the surgical management and the follow-up of the patient.Summary and Conclusion. Clinicians should keep in mind that an imperforate hymen can cause abdominal growth due to hematocolpos and include it in the differential diagnosis of …
