Cardiac masses are currently studied using multimodality imaging. For diagnosis, different imaging techniques that can provide complementary information are used. Cardiac magnetic resonance imaging (MRI) has become a fundamental tool for this type of pathology owing to its ability to provide tissue characterization, spatial accuracy, and the anatomic relationships of the different structures. This study presents a series of four clinical cases with an initial diagnosis of a cardiac mass. All cases were evaluated at a single center, and patients were aged 57 to 72 years. An etiological study was conducted on all patients using different imaging techniques, including MRI. This study describes the diagnostic and therapeutic procedures of the four cases, which included two intracardiac metastases and two benign tumors. Cardiac MRI was decisive in the diagnostic process, determining the clinical decision-making in all four cases. Cardiac MRI has emerged as a pivotal technique in the diagnosis of cardiac masses. It can provide a highly accurate histological diagnosis without the need for invasive techniques.

Published: April 2023

Background and Objectives: Impaired wound healing represents an unsolved medical issue with a high impact on patients’ quality of life and global health care. Even though hypoxia is a significant limiting factor for wound healing, it reveals stimulating effects in gene and protein expression at cellular levels. In particular, hypoxically treated human adipose tissue-derived stem cells (ASCs) have previously been used to stimulate tissue regeneration. Therefore, we hypothesized that they could promote lymphangiogenesis or angiogenesis. Materials and Methods: Dermal regeneration matrices were seeded with human umbilical vein endothelial cells (HUVECs) or human dermal lymphatic endothelial cells (LECs) that were merged with ASCs. Cultures were maintained for 24 h and 7 days under normoxic or hypoxic conditions. Finally, gene and protein expression were measured regarding subtypes of VEGF, corresponding receptors, and intracellular signaling pathways, especially hypoxia-inducible factor-mediated pathways using multiplex-RT-qPCR and ELISA assays. Results: All cell types reacted to hypoxia with an alteration of gene expression. In particular, vascular endothelial growth factor A (VEGFA), vascular endothelial growth factor B (VEGFB), vascular endothelial growth factor C (VEGFC), vascular endothelial growth factor receptor 1 (VEGFR1/FLT1), vascular endothelial growth factor receptor 2 (VEGFR2/KDR), vascular endothelial growth factor receptor 3 (VEGFR3/FLT4), and prospero homeobox 1 (PROX1) were overexpressed significantly depending on upregulation of hypoxia-inducible factor 1 alpha (HIF-1a). Moreover, co-cultures with ASCs showed a more intense change in gene and protein expression profiles and gained enhanced angiogenic and lymphangiogenic potential. In particular, long-term hypoxia led to continuous stimulation of HUVECs by ASCs. Conclusions: Our findings demonstrated the benefit of hypoxic conditioned ASCs in dermal regeneration concerning angiogenesis and lymphangiogenesis. Even a short hypoxic treatment of 24 h led to the stimulation of LECs and HUVECs in an ASC-co-culture. Long-term hypoxia showed a continuous influence on gene expressions. Therefore, this work emphasizes the supporting effects of hypoxia-conditioned-ASC-loaded collagen scaffolds on wound healing in dermal regeneration.

Τhis study aims to measure the abundance of microplastic (MP) particles in the soft tissue of mussel (Mytilus galloprovincialis) and pearl oyster (Pinctada imbricata radiata) specimens. Samples were collected at four sites in Greece (Sagiada, Malesina, Elounda, Rhodes) from wild and farmed populations. The identification of MPs was accomplished by Raman spectroscopy. Comparisons were made between the two different species where the two species co-existed (Malesina), between the four study sites (five sampling stations) in relation to P. imbricata radiata individuals, and also in every station for the different MP types found. For the specimens from Malesina, M. galloprovincialis had more MPs in their soft tissue compared to P. imbricata radiata. Microfibers were found in abundance in M. galloprovincialis, while microfragments were found in P. imbricata radiata specimens. The main MP type found in P. imbricata radiata specimens was microfragments in all five sampling stations, and ranged between 1.54 ± 0.63 (Rhodes-baskets) and 3.56 ± 0.35 (Sagiada) MP particles/g. While the samples of mussels and pearl oysters were similar in age, the differences found in the concentrations of MPs appears to be due to their different farming methods and location characteristics concerning the five sampling stations of pearl oysters. This study indicates that the culturing system does not affect MP concentration in bivalves, and further investigation is needed to find the most appropriate method to limit and reduce MPs that end up in the farmed organisms.

Malaria is a parasitic infection caused by a protozoon of the genus Plasmodium, transmitted to humans by female biting mosquitoes of the genus Anopheles. Chloroquine and its derivates have caused the parasite to develop drug resistance in endemic areas. For this reason, new anti-malarial drugs as treatments are crucial. This work aimed to evaluate the humoral response. with hyper-immune sera, of mice immunized with six derivatives of tetrahydro-(2H)-1,3,5-thiadiazine-2-thione (bis-THTT) by indirect ELISA test. The cross-reactivity between the compounds as antigens and their microbial activity on Gram-positive and Gram-negative bacteria was evaluated. The results of the humoral evaluation by indirect ELISA show that three bis-THTTs react with almost all of the above. Besides, three compounds used as antigens stimulate the BALB/c mice’s immune system. The best combination of two antigens as a combined therapy displays similar absorbances between the antigens in the mixture, showing similar recognition by antibodies and their compounds. In addition, our results showed that different bis-THTT presented antimicrobial activity on Gram-positive bacteria, mainly on Staphylococcus aureus strains, and no inhibitory activity was observed on the Gram-negative bacteria tested.

Published: April 2023

Nitrides of aluminum (Al) and titanium (Ti) mixtures have long been studied and used as commercial coatings because of their high hardness and high oxidation resistance due to the formation of an alumina layer on the coating surface. To fully understand the contribution of Al and Ti to the properties of the film, a combinatorial deposition approach was employed using half-disk targets. Film growth was carried out using a magnetron sputtering system powered by a 13.56 MHz radio frequency power supply with varying argon (Ar) and nitrogen (N2) gas ratios. Depending on the location of the substrate relative to the target, atomic percent gradients of 0.60–0.70 Al and 0.30–0.40 Ti across the substrate surface were obtained from energy dispersive X-ray spectral analysis. X-ray diffraction peaks at 43.59°, 74.71° (face-centered cubic), and 50.60° (wurtzite) confirmed the presence of aluminum titanium nitride (AlTiN) mixtures, with an increasing amount of wurtzite phase at higher Al concentrations. For all samples, cauliflower-like nanograins were obtained and samples of the 80:20 Ar:N2 gas pressure ratio showed the smallest grain size among the three gas ratio combinations. The 80:20 Ar:N2 films revealed a relatively high hardness compared to the other gas ratios. All thin films exhibited good adhesion to 304 stainless steel substrates.

Authors: Walter Andreas , Witt Gerd , Platt Sebastian , Kleszczynski Stefan
Published: April 2023

In modern cold rolling mills in the steel industry, iron oxide powder is produced as a by-product when used pickling agents are recycled. Further processing of these iron oxide powders could enable the production of iron powder for various applications in powder metallurgy. For this purpose, a new process route with an eco-friendly hydrogen reduction treatment was developed. The process is able to manufacture a variety of iron particles through minor process adaptations. It was possible to manufacture spherical iron particles with high flowability. The flowability was measured by a Revolution Powder Analyzer, and an avalanche angle of 47.7° of the iron particles was determined. In addition, the bulk density measurements of the processed iron particles collective achieved values of 3.58 g/cm3, and a spherical morphology could be observed by SEM analysis. The achieved properties of the iron particles show high potential for applications where high flowability is required, e.g additive manufacturing, thermal spray and hot isostatic pressing. By adjusting the process conditions of the developed process, irregular iron particles could also be manufactured from the same iron oxide powder with a very high specific surface of 1640 cm2/g and a low bulk density of 1.23 g/cm3. Therefore, the property profile is suitable as a friction powder metallurgy material. In summary, the developed process in combination with the iron oxide powder from steel production offers a cost-efficient and sustainable alternative to conventional iron powders for additive manufacturing and friction applications.
On the Origins of the Alexandrian School: Rhizomes, Episcopal Legitimation, and a Tale of Two Cities
Authors: Kyriacou Chrysovalantis
Published: April 2023

This article revisits an important and much-discussed question: how and why was Christian learning in second- and third-century Alexandria institutionalised, leading to what came to be known as the “Catechetical School”? Its contribution to scholarship lays in that it focuses on cultural, ideological, and ecclesiastical developments under the Antonines and the Severans, placing the Alexandrian case within a broader context. Building on Deleuze and Guattari’s concept of the rhizome, our examination seeks to map the complex web of interactions among the Christians themselves, as well as between Christians and non-Christians, so as to understand more deeply the mechanics behind the institutional establishment of the Alexandrian School. Berger and Luckmann’s theory on the relationship between institutions and knowledge frames our analysis of episcopal legitimation and the reception of the Alexandrian School’s origins by Eusebius of Caesarea. As will be argued, the early history of the School is largely “a tale of two cities”, in the sense that parallel and transverse processes in Alexandria and Rome reflect the plurality of Christian responses to pressing challenges.
A Study of R-R Interval Transition Matrix Features for Machine Learning Algorithms in AFib Detection
Authors: Patel Sahil , Wang Maximilian , Guo Justin , Smith Georgia , Chen Cuixian
Published: April 2023

Atrial Fibrillation (AFib) is a heart condition that occurs when electrophysiological malformations within heart tissues cause the atria to lose coordination with the ventricles, resulting in “irregularly irregular” heartbeats. Because symptoms are subtle and unpredictable, AFib diagnosis is often difficult or delayed. One possible solution is to build a system which predicts AFib based on the variability of R-R intervals (the distances between two R-peaks). This research aims to incorporate the transition matrix as a novel measure of R-R variability, while combining three segmentation schemes and two feature importance measures to systematically analyze the significance of individual features. The MIT-BIH dataset was first divided into three segmentation schemes, consisting of 5-s, 10-s, and 25-s subsets. In total, 21 various features, including the transition matrix features, were extracted from these subsets and used for the training of 11 machine learning classifiers. Next, permutation importance and tree-based feature importance calculations determined the most predictive features for each model. In summary, with Leave-One-Person-Out Cross Validation, classifiers under the 25-s segmentation scheme produced the best accuracies; specifically, Gradient Boosting (96.08%), Light Gradient Boosting (96.11%), and Extreme Gradient Boosting (96.30%). Among eleven classifiers, the three gradient boosting models and Random Forest exhibited the highest overall performance across all segmentation schemes. Moreover, the permutation and tree-based importance results demonstrated that the transition matrix features were most significant with longer subset lengths.
Application of Magnetic Adaptive Testing for Nondestructive Investigation of 2507 Duplex Stainless Steel
Authors: Vértesy Gábor , Mészáros István , Bögre Bálint
Published: April 2023

Duplex stainless steels are two-phase alloys, which contain ferritic and austenitic phases in their microstructure. Their duplex structure provides exceptional resistance to pitting and chloride stress corrosion cracking, and their strength is about twice that of austenitic stainless steels. Due to their good properties, they are widely used in chemical and petrochemical industries as a base material in pressure vessels, pipelines and containers. Duplex stainless steel samples were nondestructively investigated by measuring sets of magnetic minor hysteresis loops using the method called magnetic adaptive testing (MAT). Several series of heat-treated and cold-rolled 2507 duplex stainless steels were measured, and the magnetic parameters were compared with the results of the DC magnetometry of the samples. It was found that the changes in the material properties that were generated by heat treatment and mechanical deformation could easily be followed by magnetic measurements. In contrast to DC magnetic measurements, good correlation was found with the magnetic parameters determined by MAT method and Vickers hardness. Based on our experiments, MAT seems to be a powerful tool for the nondestructive characterization of duplex stainless steels.
Cluster Validity Index for Uncertain Data Based on a Probabilistic Distance Measure in Feature Space
Authors: Ko Changwan , Baek Jaeseung , Tavakkol Behnam , Jeong Young-Seon
Published: April 2023

Cluster validity indices (CVIs) for evaluating the result of the optimal number of clusters are critical measures in clustering problems. Most CVIs are designed for typical data-type objects called certain data objects. Certain data objects only have a singular value and include no uncertainty, so they are assumed to be information-abundant in the real world. In this study, new CVIs for uncertain data, based on kernel probabilistic distance measures to calculate the distance between two distributions in feature space, are proposed for uncertain clusters with arbitrary shapes, sub-clusters, and noise in objects. By transforming original uncertain data into kernel spaces, the proposed CVI accurately measures the compactness and separability of a cluster for arbitrary cluster shapes and is robust to noise and outliers in a cluster. The proposed CVI was evaluated for diverse types of simulated and real-life uncertain objects, confirming that the proposed validity indexes in feature space outperform the pre-existing ones in the original space.

Published: April 2023

Concentric tube robots (CTRs) are a promising prospect for minimally invasive surgery due to their inherent compliance and ability to navigate in constrained environments. Existing mechanics-based kinematic models typically neglect friction, clearance, and torsion between each pair of contacting tubes, leading to large positioning errors in medical applications. In this paper, an improved kinematic modeling method is developed. The effect of clearance on tip position during concentric tube assembly is compensated by the database method. The new kinematic model is mechanic-based, and the impact of friction moment and torsion on tubes is considered. Integrating the infinitesimal torsion of the concentric tube robots eliminates the errors caused by the interaction force between the tubes. A prototype is built, and several experiments with kinematic models are designed. The results indicate that the error of tube rotations is less than 2 mm. The maximum error of the feeding experiment does not exceed 0.4 mm. The error of the new modeling method is lower than that of the previous kinematic model. This paper has substantial implications for the high-precision and real-time control of concentric tube robots.
RIS-Assisted Hybrid Beamforming and Connected User Vehicle Localization for Millimeter Wave MIMO Systems
Authors: Sarker Md. Abdul Latif , Son Woosung , Han Dong Seog
Published: April 2023

A reconfigurable intelligent surface (RIS) is a type of metasurface that can dynamically control the reflection and transmission of electromagnetic waves, such as radio waves, by changing its physical properties. Recently, RISs have played an important role in intelligently reshaping wireless propagation environments to improve the received signal gain as well as spectral efficiency performance. In this paper, we consider a millimeter wave (mmWave) vehicle-to-vehicle (V2V) multiple-input multiple-output (MIMO) system in which, an RIS is deployed to aid downlink V2V data transmission. In particular, the line-of-sight path of the mmWave system is affected by blockages, resulting in higher signaling overhead. Thus, the system performance may suffer due to interruptions caused by static or mobile blockers, such as buildings, trees, vehicles, and pedestrians. In this paper, we propose an RIS-assisted hybrid beamforming scheme for blockage-aware mmWave V2V MIMO systems to increase communication service coverage. First, we propose a conjugate gradient and location-based hybrid beamforming (CG-LHB) algorithm to solve the user sub-rate maximization problem. We then propose a double-step iterative algorithm that utilizes an error covariance matrix splitting method to minimize the effect of location error on the passive beamforming. The proposed algorithms perform quite well when the channel uncertainty is smaller than 10%. Finally, the simulation results validate the proposed CG-LHB algorithm in terms of the RIS-assisted equivalent channel for mmWave V2V MIMO communications.
A Multi-Modal Under-Sensorized Wearable System for Optimal Kinematic and Muscular Tracking of Human Upper Limb Motion
Authors: Bonifati Paolo , Baracca Marco , Menolotto Mariangela , Averta Giuseppe , Bianchi Matteo
Published: April 2023

Wearable sensing solutions have emerged as a promising paradigm for monitoring human musculoskeletal state in an unobtrusive way. To increase the deployability of these systems, considerations related to cost reduction and enhanced form factor and wearability tend to discourage the number of sensors in use. In our previous work, we provided a theoretical solution to the problem of jointly reconstructing the entire muscular-kinematic state of the upper limb, when only a limited amount of optimally retrieved sensory data are available. However, the effective implementation of these methods in a physical, under-sensorized wearable has never been attempted before. In this work, we propose to bridge this gap by presenting an under-sensorized system based on inertial measurement units (IMUs) and surface electromyography (sEMG) electrodes for the reconstruction of the upper limb musculoskeletal state, focusing on the minimization of the sensors’ number. We found that, relying on two IMUs only and eight sEMG sensors, we can conjointly reconstruct all 17 degrees of freedom (five joints, twelve muscles) of the upper limb musculoskeletal state, yielding a median normalized RMS error of 8.5% on the non-measured joints and 2.5% on the non-measured muscles.
Full-BAPose: Bottom Up Framework for Full Body Pose Estimation
Authors: Artacho Bruno , Savakis Andreas
Published: April 2023

We present Full-BAPose, a novel bottom-up approach for full body pose estimation that achieves state-of-the-art results without relying on external people detectors. The Full-BAPose method addresses the broader task of full body pose estimation including hands, feet, and facial landmarks. Our deep learning architecture is end-to-end trainable based on an encoder-decoder configuration with HRNet backbone and multi-scale representations using a disentangled waterfall atrous spatial pooling module. The disentangled waterfall module leverages the efficiency of progressive filtering, while maintaining multi-scale fields-of-view comparable to spatial pyramid configurations. Additionally, it combines multi-scale features obtained from the waterfall flow with the person-detection capability of the disentangled adaptive regression and incorporates adaptive convolutions to infer keypoints more precisely in crowded scenes. Full-BAPose achieves state-of-the art performance on the challenging CrowdPose and COCO-WholeBody datasets, with AP of 72.2% and 68.4%, respectively, based on 133 keypoints. Our results demonstrate that Full-BAPose is efficient and robust when operating under a variety conditions, including multiple people, changes in scale, and occlusions.

Published: April 2023

The applicability of clinoptilolite zeolites in controlling the emission of greenhouse gases (GHGs) such as CO2, the most significant GHG, is investigated herein. In this research, Mexican natural zeolites (ATN) originating from an Atzinco deposit in the state of Puebla were used. Samples of modified clinoptilolite (ATH4, ATH3, ATH2 and ATH1) were obtained from the starting material by acid treatment of various intensities. Inverse gas chromatography was used to evaluate CO2 adsorption in clinoptilolite, natural and chemically modified. Adsorption of CO2 was investigated in the temperature range of 433–573 K, using a TCD detector, and He as a carrier gas. The experimental CO2 adsorption data were processed by Freundlich and Langmuir equations. The degree of interaction between CO2 and the dealuminated clinoptilolite samples was examined through the evaluation of the isosteric enthalpy of adsorption. This calculation was made by using the Clausius–Clapeyron equation, which established the following sequence: ATH1 > ATH2 > ATH4 > ATN > ATH3. The nanoporosity of these clinoptolite zeolites from new deposit in sedimentary rocks was studied through HRADS adsorption of N2. Simultaneously, these zeolites were, respectively, characterized by XRD, EDS, and SEM. Micropores are described by the Dubinin–Asthakov distribution. Various adsorption mechanisms that occur in these nanoporous materials at different relative pressures can be visualized. The quantitative determination of starting mineral is described as: Ca-Clinoptilolite (88.76%) >> Montmorillonite (11.11%) >> quartz (0.13%). The Si/Al molar ratio after acid treatment is: ATH4 > ATH2 > ATN > ATH3 > ATH1. The Langmuir specific surface area (ASL) varies as follows: ATN > ATH2 > ATH4 > ATH3 > ATH1. At the same time, the VΣ values are as follows: ATN > ATH4 > ATH3 > ATH1 > ATH2.

Published: April 2023

Purpose: To evaluate the usefulness of CT temporal subtraction (TS) images for detecting emerging or growing ectopic bone lesions in fibrodysplasia ossificans progressiva (FOP). Materials and Methods: Four patients with FOP were retrospectively included in this study. TS images were produced by subtracting previously registered CT images from the current images. Two residents and two board-certified radiologists independently interpreted a pair of current and previous CT images for each subject with or without TS images. Changes in the visibility of the lesion, the usefulness of TS images for lesions with TS images, and the interpreter’s confidence level in their interpretation of each scan were assessed on a semiquantitative 5-point scale (0–4). The Wilcoxon signed-rank test was used to compare the evaluated scores between datasets with and without TS images. Results: The number of growing lesions tended to be larger than that of the emerging lesions in all cases. A higher sensitivity was found in residents and radiologists using TS compared to those not using TS. For all residents and radiologists, the dataset with TS tended to have more false-positive scans than the dataset without TS. All the interpreters recognized TS as useful, and confidence levels when using TS tended to be lower or the same as when not using TS for two residents and one radiologist. Conclusions: TS improved the sensitivity of all interpreters in detecting emerging or growing ectopic bone lesions in patients with FOP. TS could be applied further, including the areas of systematic bone disease.

Energy Management and Optimization of Large-Scale Electric Vehicle Charging on the Grid
Authors: Kene Raymond O. , Olwal Thomas O.
Published: April 2023

The sustainability of a clean energy transition for electric vehicle transportation is clearly affected by increased energy consumption cost, which is associated with large-scale electric vehicles (EVs) charging on a fossil-fuel dependent electricity grid. This places a potential threat on the safe operations and stability of the grid and increases the emissions of greenhouse gases (GHGs) from the power stations that generate the electricity. Furthermore, the uncontrolled large-scale integration of EVs charging on the grid will increase exponentially in the coming years. Because of this, new peaks on the grid will be generated due to the EV charging load variance, and a significant impact on the transformer limit and substation capacity violation will occur. To mitigate the significant impact of the high cost of energy consumption by large-scale EVs charging on the grid, and to reduce the emissions of GHGs, there is a need to provide a multi-level optimization approach that is robust and dynamic to solve the uncontrolled charging problem of large-scale integration of EVs to the grid. This paper investigates the grid energy consumption by EVs and reviews recent applications of EV charging controls and optimization approaches used for the energy management of large-scale EVs charging on the grid. Energy management in this context is not trivial. It implies that the objectives such as load shifting, peak shaving, and minimizing the high cost of electricity consumption with a stable grid operation can be achieved. In the context of this study, EVs charging on the grid includes both battery electric vehicles (BEVs), which have larger battery banks with a longer charging duration and higher energy consumption capacity, and plug-in hybrid electric vehicles (PHEVs) which have smaller battery capacities.
Emotional Regulation Underlies Gender Differences in Pathological Eating Behavior Styles of Bariatric Surgery Candidates

Published: April 2023

Almost a third of bariatric surgery patients present suboptimal weight loss or important weight regain in the first five postoperative years. While the reasons underlying this are not fully understood, it is known that pathological eating styles (such as emotional or binge eating) can thwart efforts to maintain weight loss. However, detailed characterization and understanding of these eating styles have yet to be achieved. In particular, research on gender differences in pathological eating styles and psychiatric symptoms before bariatric surgery is lacking. To characterize gender differences in eating styles and their association with clinical symptoms, we prospectively enrolled 110 bariatric surgery candidates, collecting eating styles and clinical scores. Women displayed a higher frequency of emotional eating as compared to men (x2 = 9.07, p = 0.003), while men showed a higher frequency of quantitative eating behavioral style (x2 = 4.58, p = 0.044). Binge eating style was associated with higher Difficulties in Emotion Regulation Scale (DERS), Hamilton Depression Scale (HAM-D), and Hamilton Anxiety Scale (HAM-A) scores (p < 0.05). Emotional eating style was associated with higher HAM-D and HAM-A scores (p < 0.05). The present findings highlight the importance of understanding the role of gender differences in emotion regulation processes involved in the development and maintenance of pathological eating styles in bariatric surgery candidates. This paves the way to gender- and symptoms-specific interventions on eating behaviors to improve surgery long-term outcomes.

Sur la prévalence féminine de l'anorexie mentale
Authors: Brusset Bernard
Published: April 2023

Bernard Brusset, On female prevalence in anorexia nervosa.

To explain the remarkable female predominance in anorexia nervosa, one usually stays within general platitudes, putting forward a vague "plurifactorial determinism", or unduly privileging one type of factor over others. The confrontation of biological, epidemiological and historical data with clinical processes and with data from psychoanalytic psychotherapies enables us to try to specify how, and by which mechanism, different factors intervene in the anorectic process. Evaluating the possible action of biological, cultural, family factors that can be more or less present depending on the case, all the more emphasises the importance of the problematic of adolescence, and of certain specificities of the girl's libidinal development.

Catherine Béhar-Azoulay, Feminidad y filiación : la prueba del tiempo.

Este artículo expone un cierto numéro de reflexiones que conciernen la relación al tiempo de la jovencita confrontada al proceso de fin de la adolescencia y que debe realizar elecciones que implican su vida presente y sobre todo futura. Retomando algunas referencias esenciales de autores que han trabajado sobre la adolescencia, la identidad y el tiempo, el autor pone el acento sobre la importancia del anclaje del sujeto en su filiación para que un proyecto de existencia pueda madurar, luego concretarse. Es el arraigo de un sujeto en su filiation que le permite, ante todo, conjugar su existencia por siempre, asegurar su continuidad y tomar a cargo una historia personal. La joven entre 18 y 22 anos está, tal vez, más solicitada en ese sentido que el joven, en la medida que el tiempo "femenino" se comprende en referencia al espacio-tiempo de la maternidad. Estos propósitos sern ilustrados a través de ejemplos de producciones en las pruebas proyectivas del Rorschach y del TAT.

Pierre Noaille, Un pensamiento, "reino del entre-dos".

"Cuestión límite", a primera vista, para un psicoanálisis identificado en tanto que "ciencia de las profundidades" enteramente centrado sobre ese "núcleo" que es el inconsciente, el pensamiento puede, en efecto, encontrar su lugar en la periferia, tendremos por lo tanto que reconocer que el proyecto freudiano hace de ese "límite" su ideal, el punto de perspectiva a alcanzar implícitamente. Un límite - "la envoltura" - en lo que él implica de "síntesis", que el psicoanálisis parece no obstante temer en tanto que él apuesta sobre su intervención. Es que el psicoanálisis no sería otra cosa que un movimiento de pensamiento que tiene esa particularidad de problematizar su propio movimiento ? El lo sitúa, y haciéndose, sitúa "su" propio campo, precisamente en el "entre-dos" del par solidario "núcleo"-"envoltura". La "categoría de lo intermediario" - epistemología fundadora para el campo freudiano - se désigna así como el elemento conceptual verdaderamente apropiado a una problemática del proceso de pensamiento.

Michèle Montreuil, Incest and maltreatment : comparative study with Rorschach.

We met 17 women in an association called "aid to victims". These women had suffered from maltreatment in childhood. Our method was based on clinical interviews and on Rorschach. We notice that identity and identification are fragile. The variable degree of fragility does not seem to be linked to the trauma itself but appears to be at the origin of depression. For some women victims of childhood incest, clinical interview and projective tests show confusion in family roles and generations and the reexperiencing of the sexual trauma in the present. In reference to Freud's theory on the second trauma, sexual abuse could constitute a screen trauma, hiding the first trauma related to primary maternal negligence or maltreatment.

Key-words : Childhood maltreatment, incest, maternal neglect, long-term trauma effect, clinical study.

Basing her research on a sociological study of the phenomenon of life on the skids ("la galère") among young people, the author draws her inspiration from this model and employs it as a metaphor to be applied at the clinical level to borderline pathologies of adolescence.

Herein, she will attempt to establish the metapsychological status of violence on a theoretical as well as a clinical level in the domains of neurosis and of borderline organizations, through the works of Freud and of other authors, by inquiring into the nature, the place and the destinies of aggressivity in the psychic apparatus.

This reflection, which takes environmental conditions into account in the construction of the psyche, gives a central position to the notion of the drive object in its function of an objectal limit which may have proved ineffective in certain cases of violence.

Key-words : violence, adolescence, the skids (« galère »), environment, limit, Superego, narcissism, object, drive.
Violence de l'adolescent et angoisse de démembrement
Authors: Nevjinsky Fern
Published: April 2023

Fern Nevjinsky, Adolescent violence and dismemberment anxiety.

By following the evolution of approximately forty adolescents for the past few years, we have been able to determine the signs which are frequently linked to the occurrence of violent acts. Starting from the interpretation of these data, the author has hypothesized that for these adolescents, the work of mourning cannot be accomplished normally and is replaced by a work of melancholy which appears during a massive narcissistic regression. The encounter between aggressive maternal introjects and the presence of a "clinging" maternal imago can generate "dismemberment anxiety", a consequence of instinctual disentanglement and the failure to establish a primary erogenous masochistic core.

Key-words : Adolescence, dismemberment anxiety, masochism, death instinct, work of melancholy.

L'évaluation de l'intelligence : complexité du diagnostic à l'adolescence
Authors: Pelanda Eugenia
Published: April 2023

Eugenia Pelanda, La evaluación de la inteligencia. Complejidad del diagnóstico en la adolescencia.

La evaluación diagnóstica en la adolescencia es una aproximación compleja y delicada. Se trata de presentar el functionamiento global del adolescente distinguiendo conflictos de desarrollo y procesos psicopatológicos, evitando al mismo tiempo de encasillar al sujeto en un modelo psicopatológico que fije la descripción sobre un modo estructural y Ueve a perder de vista la dimensión dinámica, los recursos, las potencialidades. Nosotros nos focalisaremos sobre un aspecto de la consulta psicodiagnóstica en la adolescencia : la evaluación de la inteligencia a la luz de numerosas contribuciones que, en dominios teóricos diferentes, han intentado comprender de manera holística los aspectos afectivos y cognitivos del desarrollo humano. Daremos también algunas indicaciones prácticas que podrán abrír el camino a una mejor comprensión en un dominio hasta ahora poco explorado pero, según nuestra opinion, de una importancia central en el curso de esta etapa evolutiva.

La névrose. Perspectives psychanalytiques
Authors: Séchaud Évelyne
Published: April 2023

Évelyne Séchaud, La neurosis. Perspectivas psicoanaliticas.

En una perspectiva psicoanalítica, la neurosis encuentra su unidad estructural en las viscisitudes del complejo de Edipo y del complejo de castración. Las dos grandes neurosis, histérica y obsesiva, se completan y se oponen sobre la organizacion del conflicto y el modo de pensamiento.

La histeria es un conflicto entre el amor y la sexualidad. La neurosis obsesiva es un conflicto de ambivalencia entre el amor y el odio.

El modo de pensamiento neurótico realiza una separación de la representacion y del afecto. En la histeria, la representacion es reprimida, el afecto convertido y reprimido,o transformado en angustia. La condensación es prévalente. En la neurosis obsesiva, el afecto es desplazado sobre una representación anodina, la representación conflictiva queda reprimida ; el afecto que subsiste es un afecto de remordimientos y de angustia moral, el súper-yo tomando por su cuenta la amenaza de castración.

Palabras-clave : Neurosis, Histeria, Neurosis obsesiva, Conflicto psíquico, Afecto, Representacion, Condensación, Desplazamiento.
La place du narcissisme dans l'évaluation de la névrose à l'adolescence : éclairage projectif
Authors: Emmanuelli Michèle
Published: April 2023

Both response sets are compared to that of a third, control group. The study of narcissism is done by using Rorschach and TAT protocols with a specific methodology applied in addition to the classical analysis. This study refines the differential diagnosis. It makes it possible to separate out the favorable cases in which narcissistic cathexes are articulated to objectai cathexes, from cases for which the narcissistic vulnerability portends a more serious non neurotic evolution.

« Les idées consentantes » : un cas de névrose chez un préadolescent
Authors: Chagnon Jean-Yves
Published: April 2023

Jean-Yves Chagnon, Las ideas consentidas : un caso de neurosis en un pre-adolescente.

Un caso de pre-adolescente neurótico visto a los 12 años en consulta, luego revisto en el cuadro de una investigación a los 16 anos, y posteriormente a los 20 años, servirá para ilustrar nuestra hipótesis : la pre-adolescencia en la continuación de la latencia, es un período de intenso trabajo psíquico preparatorio para la adolescencia, pero las desestabilizaciones que allí se producen por encima de la pubertad, la vuelven incierta, llena de movimientos heterogéneos y contradictonos. La fórmula neurotica del sujeto se disuelve allí, encubierta por la inhibición a decir y la excitación comportamental. Los procesos psíquicos que permiten proponer una evaluación diagnóstica y pronóstica, no obstante, son considerados « après-coup ».

La mentalisation à l'épreuve de l'examen psychologique. Illustration clinique
Authors: Samai Haddadi Dalila
Published: April 2023

Dalila Samai Haddadi, La mentalización en la prueba del examen psicológico. Ilustracion clínica.

El reconocimiento de la expresión de la sintomatología mental positiva con los instrumentos del psicólogo clínico, constituye el objetivo de este trabajo. Por medio de una ilustración clínica, el articulo hace referencia, sobretodo, a una gestion de evaluación de la mentalización que se expresa tan bien en las pruebas proyeetivas como en las pruebas de eficiencia. Adoptando esta gestión, la reflexión provocada tiende a confirmar la hipótesis psicosomática según la cual la mentalización protege el cuerpo de las desorganizaciones somáticas.
