description: Pelvic Incidence is defined as the angle between the perpendicular line to the upper plate of S1 at its midpoint and the line between this point and the center of bicoxofemoral line, it describes the position of femural heads in relation to sacrum. Recently some authors described a direct correlation between high values of PI and large AP pelvic axis (horizontal pelvis) and a wide pelvic ring [1]. Also the acetabular orientation is influenced by PI ; high values of PI means a more vertical acetabulum. Having regard to the relationship between PI and the main structures involved in the load transfer, to date no studies that correlate the morphology of the Sacroiliac Joint (SiJ) and PI were performed. The aim of this study is to evaluate the different morphology of the auricular surface of the sacrum comparing two groups of healthy young people with low (<40°) and high (>40°) PI. We retrospectively analysed 51 consecutive young (between 20 and 35 y.o.) people. After the evaluation of PI the sample was divided into two groups: 31 people belong to the group A (PI < 40°) and 20 people belong the the group B (PI >40°). The following morphological parameters of the SiJ were analysed: length of long axis (LLA), length of short axis (LSA), length of oblique axis (LOA), ratio between long and short axis (RLSA), angle between axis (ABA) and surface; global shape of the joint was evaluated; two new parameters were introduced, SiJ Tilt (SiJT), defined as the angle between the vertical line and the long axis of the SiJ and SiJ Slope (SiJS), defined as the angle between the horizontal line and the short axis of the SiJ. We found a strong statistically significant correlations (p-value 0.05) between PI and RLSA, shape, ABA, SiJT and SiJS; a weaker correlations (p-value 0.10) between PI and LLA, LSA were observed; no statistically significant correlation between PI and LOA and surface were observed. The results underline that there is a strong correlation between pelvic morphology and SiJ anatomy. Further studies, about the different pattern of forces distribution among SiJ, will need to be performed to have a better knowledge that could help to understand the biomechanics and pathophysiology of normal and pathological SiJ.

description: In humans, vertical posture acquisition caused several changes in bones and muscles which can be assumed as verticalization. It’s widely known that six different morphological categories exist; each category differs from the others by pelvic parameters and vertebral column curvatures. Both values depend on the Pelvic Incidence, calculated as the angle between the axis passing through the rotation centre of the two femur heads and the vertical axis passing through the superior plate of the sacrum. The aim of this study is to evaluate the distribution of stress and the resulting strain along the axial skeleton using finite element analysis. The use of this computational method allows performing different analyses investigating how different bony geometries and skeletal structures can behavior under specific loading conditions. A CT of artificial bones, was used to obtain geometrical data of the model developed. Lines were imported into a commercial code in order to interpolate main surfaces and create the solid version of the model. Six different models were created according Roussouly’s classification, by arranging geometrical position of the skeletal components. Loading conditions were obtained by applying muscular forces components to T1 to L5, and a fixed constrain was at the distal epiphisis of femurs. Materials were assumed as elastic; Elastic modulus of 15 GPa, a Shear Modulus of 7 GPa for bony parts; Elastic modulus of 6 MPa, a Shear Modulus of 3 MPa for cartilaginous parts [1]. Six different simulations have been carried out. Results confirm higher solicitations obtained varying configurations from case I to case VI. In particular way, first three cases seem to supply the different loading configurations spreading stresses in almost all the bony parts of the column, while the remaining others three cases produce a higher concentration of stress around the lower part of spine (L3, L4, L5). Results confirm a good agreement with those present in literature, an equivalent Von Mises average stress of 0,55 MPa was found on the intervertebral disks with the higher values reached on the lower part of the model. A comparison of results obtained for Case I with literature, shows a good agreement in terms of normal compressive force, while more evident differences can be found for shear force and sagittal moment. The results underline a relationship between PI increase, and accordingly of PT and LL, and the distribution of load forces. Load forces is exerted mainly on distal vertebrae, especially on L4 and L5.

description: Background: In most of Western and European countries, reimbursement for the treatment of vein disorders depends upon the severity of the disease. This is currently evaluated according only to skin appearance (normal skin, edema, cutaneous changes and finally ulceration). Aim: In this study, the occurrence of skin damaging was evaluated by ultrasonography in varicose legs with apparently normal skin (excluded from reimbursement in many countries). Methods : Only legs with extensive varicose veins were considered (reflux originating from the saphenofemoral junction and descending along the great saphenous vein down to the lower leg). US findings fom the varicose leg were compared to those from the contra lateral healthy limb. Results: In 13/18 varicose legs, skin changes related to inflammation were observed: dermal edema, subcutaneous edema, dermal or subcutaneous infiltration. In these legs, scoring for venous symptoms resulted higher than in the remaining 5 legs. Discussion: Sonography demonstrated the occurrence of cutaneous and/or subcutaneous inflammation in varicose legs with apparently normal skin. These objective signs correlate to heavier symptoms and greater limitation in working, domestic and social activities. Possible forensic and insurance implications are finally discussed.

description: All individuals have similar psychological needs like experiencing self-efficacy, pleasure, or attachment (Epstein, 1993; Grawe, 2006). The way to get those needs met, however, is sometimes messy, especially when vulnerability is high. While the concept of hidden resilience has been introduced two decades ago (Ungar, 2002), or more precisely within hidden resilience seem to be rather unexplored. Conceptualising hidden resources allows to extent and strengthen the social ecological perspective of resilience, wherein factors and processes of resilience are conceived as contextually dependent. Hidden affordances (Gaver, 1991; Gibson, 1979) of resources can be understood as the nonconventional behavioural patterns used on the path facilitating (hidden) resilience, hence, a resource is equipped with different qualities that are compatible with and relevant for the individual’s psychological needs. Vulnerable children might be securing resources, helping them to stay healthy, by being angry, even aggressive. Various studies (Kassis et al., 2018; Sroufe et al., 2010; Ungar, 2002; Ungar et al., 2013) are in line with a view, indicating that resilience processes are rarely linear or ideal, in the sense that only the pure self-beneficial or socially accepted resources are navigated to. By acknowledging messy resilience processes, we sharpen the view towards hidden resilience and hidden (affordances of) resources which allows us to take off our conventionally tinted resilience-glasses and recognize various resilient ways of life. The conclusion opens the field of vision regarding successful adaptation to adverse situations and provides added value for educational sciences and therapeutic areas.
title: Vergleich eines für allergische Rhinitis spezifischen mit einem generischen Verfahren zur Erfassung gesundheitsbezogener Lebensqualität
Creators: name: Hollaus, Denise
Year: 2008

description: Es wird ein neu entwickelter Fragebogen zur Messung gesundheitsbezogener Lebensqualität - spezifisch bei Patienten mit allergischer Rhinitis - vorgestellt und mit dem Short Form-36 Health Survey als generisches Verfahren verglichen. Die Daten wurden im Zuge einer klinischen Studie in der Vienna Challenge Chamber erhoben. Die klinische Studie wurde in einem randomisierten, doppelblinden, placebo-kontrollierten unvollständigen Vier-Wege-Cross-over-Design durchgeführt. Geprüft wurde die Dosis-Wirkungs-Kurve eines Nasensprays in vier verschiedenen Dosierungen im Vergleich mit einem Placebo. Die Erhebung der Lebensqualität erfolgte zu vier Zeitpunkten. Insgesamt konnten vollständige Datensätze von 57 Personen erhoben werden. Neben der Hypothesenprüfung erfolgte auch eine psychometrische Testung des neu erstellten Fragebogens. Dabei ergeben sich sehr gute Skalenqualitäten. Die Überprüfung der Änderungssensitivität des neuen Verfahrens ergibt signifikante Unterschiede zwischen der Behandlung mit der höchsten Dosierung und der Placebo-Einnahme in drei der vier Skalen. Die Reliabilitätsschätzungen nach Cronbachs Alpha fallen für die Skalen und für den Gesamtwert zufriedenstellend bis sehr gut aus. Die Überprüfung der Differenzierungsfähigkeit der beiden Fragebögen erfolgte auf Basis der relativen Validität. Die Ergebnisse sprechen für den neu erstellten Fragebogen. Drei von vier Skalen dieses neuen spezifischen Fragebogens differenzieren besser als die Skalen des generischen Instruments. Untersuchungen der Zusammenhänge von objektiven Messmethoden mit der gesundheitsbezogenen Lebensqualität ergeben sehr geringe bis geringe Korrelationen. Zusammenhänge der subjektiven Erhebungen und der gesundheitsbezogenen Lebensqualität erweisen sich als gering bis mittel. Aufgrund der guten psychometrischen Qualitäten des neuen Fragebogens und der besseren Differenzierungsfähigkeit im Vergleich mit dem generischen Instrument, ist das neue Verfahren im Kontext klinischer Studien zur allergischen Rhinitis dem generischen vorzuziehen.

description: This study examines the extent to which teachers' competence aspects as self-regulated learners and agents of self-regulated learning (SRL) explain their self-reported and students' perceived promotion of metacognition. One hundred and eighty-five lower secondary school teachers participated in this study. The results reveal positive direct relationships between teachers' knowledge, self-efficacy, intrinsic interest value and the promotion of metacognition. Teachers’ own SRL skills and mindsets about SRL were indirectly related to the promotion of metacognition via their self-efficacy and intrinsic interest value. This study provides new evidence of the importance of teachers' dual competence profile for promoting metacognition.

description: To regain walking after a neurological disorder is considered one of the primary goals of the rehabilitation process, given that gait abnormalities are often disabling, negatively impacting patients’ quality of life. In the last years there has been an intense technological development of robotic devices to overcome such problems. The robotic rehabilitation tools are typically based on the so-called phenomenon of motor learning, resulting from intensive, repetitive, and task-oriented motor activities that require patient’s effort and attention [1]. Such robotic devices can be classified into stationary and overground walking systems: stationary systems (treadmill gait trainers such as Lokomat, and programmable foot end-effector trainers including Geo-System) and overground walking systems (e.g. Ekso-GT). Stationary devices and new treadmill and balance platforms, such as C-Mill and CAREN, may be equipped with virtual reality, to further improve functional outcomes. Virtual reality is conceived to put the patient in a situation to generate the augmented feedback towards his central nervous system (augmented feedback) through exercises performed in a virtual environment which help to develop knowledge of results of the movements (knowledge of results) and knowledge of the quality of the movements (knowledge of performance). Thanks to this, the central nervous system can activate a physiological key learning mechanism called “reinforcement learning” which implies an increase of the specific information of a movement to produce an effective improvement of performance quality.

description: In obesity condition the adipose tissue undergoes molecular and cellular alterations affecting systemic metabolism via the release of different pro-inflammatory mediators. Nut-derived polyphenols and fatty acids have a documented role in the modulation of energy metabolism and antiobesity effect. We investigate the effects of Pistachia vera nuts on body fat mass and its distribution in a mouse models of obesity by Micro-computed tomography (CT). For this purpose, three groups of C57BL/6J male mice were fed for 16 weeks with a standard chow, a high fat diet (HFD) or HFD supplemented with pistachio harvested in plantation of the valley of the Platani river (Sicily). Fatty acids extraction from Pistachia vera nuts was carried out and analysed by a gas-chromatographic technique for contributing 20% of total diet energy. Total body fat mass was estimated and compared between groups by micro-CT (Quantum FX Micro CT scanner). Furthermore, the effects of pistachio consumption on total cholesterol, triglycerides, fat liver accumulation, adipose tissue inflammatory cytokines (TNFα and IL-1β) expression and serum ROS levels were also evaluated. The micro-CT slices and three-dimensional image stacks of control and obese mice showed a reduced body fat deposit and less visceral fat in mice fed HFD supplemented with pistachios. Furthermore, cholesterol and triglycerides levels, hepatic lipid accumulation, pro-inflammatory cytokines and serum ROS levels were significantly reduced in mice fed HFD supplemented with pistachio compared with the HFD mice. Our results suggest that pistachio consumption could have counteracting effects on metabolic dysfunctions in obesity through acting on the fat mass. In particular, it lower the accumulation of visceral and subcutaneous fat that could be responsible of lower level of circulating and hepatic lipids and of the decreased inflammatory condition.

description: The objective of our study is to explore the feasibility and utility of Diffusion Tensor Imaging (DTI) in the non invasive evaluation of any lesion [1] in Head and Neck structure. We would reach a verified and certified step of Virtual biopsy. Ten patients with different histological lesions were recruited for this study. Morphological and diffusion weighted images were acquired with a 3T scanner during last 3 months. Probabilistic tensor-based tractography reconstruction of any lesions was performed and mean fractional anisotropy (FA) values for everyone were extracted [2]. The results showed that the Diffusion Tensor Imaging (DTI) was able to identify the lesion geometrical morphology and diffusion microstructural changes. The patient with a benign lesion reported a significant improvement in ADC mean values. We have evidence that pushes us to continue with this method. We are at the beginning of this work. We had to recruits more patients to get meaningfully significant data.

description: Macrophages play a key role in immunity, inflammation, and atherosclerosis. Moreover, several evidences demonstrate that 17-β-estradiol (E2) plays a key role in inﬂammation and atherosclerosis through estrogen receptors (ERs) ERα and ERβ, processes that display sex differences. It has been largely demonstrated that male tissues express active ERs, but there is still lack of knowledge on their role in inflammation in males. Macrophages, which have ERα and ERβ, are a good model to evaluate the role of ER levels and activation in inflammation. The aim of our work was to evaluate the ability of lipopolysaccharide (LPS) to modulate, in a sex-specific way, the expression and the activation status of ERα and ERβ in blood monocytes-derived macrophages (MDMs) from healthy men and women. MDMs were isolated from blood of 7 adult men and 7 adult and fertile women (aged 21 - 35 years), and cultured. After 10 days of culture, MDMs were incubated with 100 ng / ml LPS for 24 h and lysed for the analysis of ERα, ERβ, P- ERα, p38 and P-p38 expression by Western Blotting. We found that in basal conditions, the expression of ERα and ERβ was significantly higher in female MDMs than in male ones. Importantly, LPS stimulation up-regulated ERα and ERα phosphorylation in both sexes, but this regulation was more pronounced in male MDMs. Moreover, LPS down-regulated ERβ level only in female MDMs. The expression of p38 and P-p38 proteins, used as marker of ERβ activity, did not display any sex differences. Finally, the ratios between ERα / ERβ and P-ERα / ERα were significantly higher in male than in female MDMs. Our findings show, for the first time, that LPS can modulate the activation of ERα but not that of ERβ, identifying a critical role of the subtype ERα in inflammatory responses mediated by LPS, at least in human MDMs. These results represent a starting point in understanding the influence of sex in the relationship between LPS and ERα.

Detection of salinity fronts from satellite observations

Publisher: name: Zenodo

description: Small-scale variability is fundamental to ocean circulation, air-sea interactions, and biogeochemical processes. In many locations, salinity variations play a more significant role than temperature in shaping density fronts. Unfortunately, current satellite data on sea surface salinity (SSS) can only capture features down to 40 km. This study focuses on analysing mesoscale variability (≤25 km) by reconstructing SSS data from satellite observations in the southwest Atlantic, in particular at the Brazil-Malvinas Confluence (BMC). This region is characterised with strong mesoscale structures and high biological activity due to the interaction of western boundary currents and cross-shelf activity. The numerical advection of satellite SSS fields using altimetric geostrophic currents produces a Lagrangian reconstruction that captures finer-scale details. These reconstructed fields are then validated with in-situ salinity measurements obtained via thermosalinograph. Results show that reconstructed SSS fields capture mesoscale structures detected by in-situ observations at the region and improves the effective resolution of SSS satellite observations.

description: We examine the deformation of homogeneous spherical fluid vesicles along their equator by a circular rigid ring. We consider deformations preserving the axial and equatorial mirror symmetries of the vesicles. The configurations of the vesicle are determined employing the spontaneous curvature model subject to the constraints imposed by the ring as well as of having constant area or volume. We determine two expressions of the force exerted by the ring, one involving a discontinuity in the derivative of the curvature of the membrane across the ring, and another one in terms of the global quantities of the vesicle. For small enough values of the spontaneous curvature there is only one sequence of configurations for either fixed area or volume. The behavior of constricted vesicles is similar for both constraints, they follow a transition from prolate to dumbbell shapes, which culminates in two quasispherical vesicles connected by a small catenoid-like neck. We analyze the geometry and the force of the small neck employing a perturbative analysis about the catenoid. A stretched vesicle initially adopts an oblate shape for either constraint. If the area is fixed the vesicle increasingly flattens until it attains a disclike shape, which we examine using an asymptotic analysis. If the volume is fixed the poles approach until they touch and the vesicle adopts a discocyte shape. When the spontaneous curvature of the vesicle is close to the mean curvature of the constricted quasispherical vesicles, the sequences of configurations of both constraints develop bifurcations, and some of the configurations corresponding to one of their branches have the lowest energy.

description: Even today there is little knowledge about the extent of homelessness in Switzerland; there is no legally binding definition of homelessness, and statistics that can be used at national level for profiling this form of poverty are scarce. This paper is based on the “First National Report on Homelessness in Switzerland” (Drilling et al., 2020). The report was motivated by the desire to share currently successful social science based research projects by the authors (especially: first national count; comparability study between Switzerland and Croatia; analysis of politics against homelessness in federalist regimes). In this paper we present findings in order to contribute a sound Swiss perspective to the European landscape of homelessness research and to highlight important future challenges.

description: Sentiment analysis of textual content has become a well-established solution for analyzing social media data. However, with the rise of images and videos as primary modes of expression, more information on social media is conveyed visually. Among these, facial expressions serve as one of the most direct indicators of emotional content in images. This study analyzes a dataset of Instagram posts related to the 2024 U.S. presidential election, spanning April 5, 2024, to August 9, 2024, to compare the relationship between textual and facial sentiment. Our findings reveal that facial expressions align with text sentiment, where positive sentiment aligns with happiness, although neutral and negative facial expressions provide critical information beyond negative valence. Furthermore, during politically significant events such as Donald Trump's conviction and assassination attempt, posts depicting Trump showed a 12% increase in negative sentiment. Crucially, Democrats use their opponent's fear to depict weakness, whereas Republicans use their candidate's anger to depict resilience. Our research highlights the potential of integrating facial expression analysis with textual sentiment analysis to uncover deeper insights into social media dynamics.

description: In diesem Praxisbeitrag fokussieren wir auf die arbeits- und organisationspsychologischen Aspekte von Fairness in der Gig Economy. An unserem aktuellen Innovationsprojekt FAMOS („Faires Arbeitsmodell ‚Office Services‘“) werden Möglichkeiten aufgezeigt und diskutiert, wie ein faires Gig-Arbeitsmodell aussehen könnte. Im Projekt gehen wir davon aus, dass Fairness in der Plattformarbeit hergestellt werden kann, indem Maßnahmen für fachliche und persönliche Entwicklung sowie Community Building angeboten werden. Dadurch wird eine gewinnbringende Beziehung im Sinne eines ausgewogenen psychologischen Vertrags zwischen Plattformbetreibenden und Leistungserbringenden gefördert. Community Building scheint zudem ein wichtiges Instrument zur Steigerung von subjektivem Gerechtigkeitsempfinden und Zugehörigkeit zu sein. Unsere ersten Erkenntnisse zeigen, dass Personalentwicklung sinnvollerweise in die Community-Strukturen integriert wird und Partizipation bei der Regelgestaltung innerhalb von Plattform und Community eine zentrale Rolle für wahrgenommene Fairness in der Gig Economy spielt.

description: We examine deep optical images of edge-on galaxies selected from the Sloan Digital Sky Survey (SDSS) Stripe\,82. The entire sample consists of over 800 genuine edge-on galaxies with spectroscopic redshifts out to $z\sim0.2$. To discern the faintest details around the galaxies, we use three different data sources with a photometric depth of down to 30 mag\,arcsec$^{-2}$ in the $r$ band: SDSS Stripe\,82, Hyper Suprime-Cam Strategic Program, and DESI Legacy Imaging Surveys. Our analysis of the deep images reveals a variety of low surface brightness features. 49 galaxies exhibit prominent tidal structures, including tidal tails, stellar streams, bridges, and diffuse shells. Additionally, 56 galaxies demonstrate peculiar structural features such as lopsided discs, faint warps, and dim polar rings. Overall, we detect low surface brightness structures in 94 galaxies out of 838, accounting for 11\% of the sample. Notably, the fraction of tidal structures is only 5.8\%, which is significantly lower than that obtained in modern cosmological simulations and observations. Previous studies have shown that strongly interacting galaxies have stellar discs about 1.5--2 times thicker than those without apparent interactions. In an analysis where tidal features are carefully masked for precise disc axis ratio measurements, we show that discs of galaxies with tidal features are 1.33 times thicker, on average, than control galaxies that do not have visible tidal features. Furthermore, we find that edge-on galaxies with tidal structures tend to have a higher fraction of oval and boxy discs than galaxies without tidal features.

title: Der Fall Pinochet - Chile 1973
Creators: name: Schendl, Georg Christoph
Year: 2008

description: Die vorliegende Arbeit behandelt die Verhaftung des ehemaligen Diktators von Chile – General Augusto Pinochet – in London am 16. Oktober 1998 und die folgenden zwei Jahre juristischen Tauziehens, die als der Fall Pinochet bekannt wurden, als zentralen Punkt. Um die Vorgänge dieses Prozesses besser zu verstehen, wird die Entwicklung Chiles vor dem Militärputsch vom 11. September 1973, an dem Pinochet als Protagonist beteiligt war, nachgezeichnet. Dabei liegt das Hauptaugenmerk auf der Regierungszeit Salvador Allendes, der in Chile ein sozialistisches Projekt auf demokratischem Wege durchsetzen wollte und im Zuge des Umsturzes ums Leben kam. Weiters wird die Diktatur Pinochets analysiert, wobei die Mechanismen der Unterdrückung und die Menschenrechtsverletzungen, aber auch die politischen und ökonomischen Veränderungen der 17 Jahre des Regimes im Vordergrund stehen. Im Anschluss daran wird der Weg Chiles zur Demokratie dargelegt und der Einfluss der Diktatur auf diesen Übergang aufgezeigt. Der Fall Pinochet wird in der Tradition der internationalen Strafgerichtsbarkeit seit dem Nürnberger Prozess verstanden und die wichtigsten Etappen dieser Entwicklung werden behandelt, bevor die Affäre um Pinochet, sein Aufenthalt in Großbritannien und die mediale Aufbereitung dieser Ereignisse analysiert werden. In weiterer Folge werden die Konsequenzen der Verhaftung Pinochets für Chile, und die Versuche ihn in seiner Heimat zur Verantwortung zu ziehen, in den Fokus gerückt. Die Auswirkungen auf die internationale Staatengemeinschaft werden ebenso nachgezeichnet wie die Gründung des Internationalen Strafgerichtshofes in den Haag. Abschließend wird das Konzept der Menschenrechte, das hinter dieser Form der Gerichtsbarkeit steht, diskutiert.

description: Dental implants rehabilitation of edentulous patients is the current accepted treatment to increase prosthetic stabilization. Various implant surface modifications have been tried to enhance osseointegration and to reduce the spread of detrimental metallic ions toward host tissues [1]. The aim of this preliminary study was to investigate in vitro the viability, proliferation and adhesion of a Bioloy® (B®) coating compared to machined and sandblasted surfaces and to assess histologically in vivo the bone response to customized mini-implants coated with B® () placed in the mandible of patients. B® is a titanium niobium nitride coating applied on surface by physical vapor deposition (Permedica Spa). It is a thin ceramic monolayer, extremely hard and with high resistance against wear, scratches and corrosion [2] Viability and adhesion was tested at 24, 48 and 72 hours after seeding of SAOS-2 on customised scaffold. Cell viability (2x104 cells) was evaluated by AlamarBlue® assay [3] and it resulted statistically higher on B® than in the other 2 groups (48 and 72 hours, p-value<0.05). No toxic response was observed. Adhesion (104 cells) was analysed by scanning electron microscope [3]. Cell morphology confirmed the healthy status. Cells adhered to the surface and proliferated, covering completely the surfaces of machined and B® at 72 hours. Osseointegration was evaluated in 2 patients. After tooth extraction, 3 MIB® were placed. Three months later, during drilling process, the biopsies with MIB® were harvested for histological processing (Donath’ protocol) [3]. In all sections MIB® resulted well osseointegrated and newly formed bone was highly mineralized and organized in lamellae (bone to implant contact 46.8%±9.15). The implant coils were filled with new bone for the 59.8% ± 4.23. Medullary spaces were rich in blood vessels without inflammatory infiltrate. In conclusion, B® is a promising coating able to enhance the viability in vitro and to favor the osseointegration in vivo.
