Mise en évidence d'une relation quantitative entre la synthèse des anticorps et celle des γ-globulines non spécifiques impliquée par la théorie de Burnet sur l'origine de la spécificité des anticorps
Authors: Valette-Robin Y. , Dupont-Mairesse N. , Jeener Raymond
Published: April 2023

1. The quantities of γ-globulins secreted in vitro by fragments of spleen, synthesized in vivo by lymph node cells during short periods, or secreted in the blood by the entire immune system of rabbits hyperimmunized against tobacco mosaic virus or the flagellae of Salmonella paratyphi have been studied by incorporation of [3H] phenylalanine. In each case the quantities of [3H] phenylalanine simultaneously incorporated into the antibodies and into the non specific γ-globulins have been found to be equal.

2. It is proposed that all antibody producing cells synthesize equal quantities of antibody and of non specific γ-globulin.

Such a parallelism might been expected if the clonal selection theory of antibody production proposed by Burnet is correct. Other interpretations are discussed.

Ionisation et dissociation de l'éthane sous l'impact électronique. Spectres de masse et phénomènes d'échange dans C2H0, C2H5D, CH3CD3 et C2D6
Authors: Or Louis d' , Collin Jacques E. , Longrée D.
Published: April 2023

Summary. — The mass spectra and appearance potentials of C2H6, C2H5D, CH3CD3 and C2D6 have been measured, in order to study the dissociation processes of ethane under electron impact.

Special attention has been drawn on the exchange phenomena occurring between hydrogen and deuterium in CH3CD3. This exchange makes difficult the study of dissociation processes. Two theoretical explanations have been previously given for the exchange phenomena, and their relative merits for the interpretation of the exchange mechanisms in ethane are discussed. Appearance potentials show that the activation energy of exchange is small. Some experimental data suggest that the rate of exchange in CH3CD3+ could be higher than 1015 sec-1 and lower than 1020 sec-1, and that exchange might also happen in fragment ions such as CH2CD2+.

Some isotope effects resulting from the substitution of hydrogen by deuterium have been observed.

Calcul du coefficient de débit de quelques tuyères débitant en atmosphère illimitée (2e note)
Authors: Jaumotte André Louis , Hirsch Charles
Published: April 2023

Dans une note antérieure (*), nous avons considéré trois tuyères débitant en atmosphère illimitée et nous avons déterminé leur coefficient de débit par le calcul de l'épaisseur de quantité de mouvement relative à la couche limite dans la section finale, pour la répartition de pression à la paroi correspondant à un écoulement par tranches parallèles. Le calcul était limité au domaine laminaire de la couche limite (Red < 1 à 1,2 105). La confrontation avec l'expérience avait montré un excellent accord.

Dans la présente note, la même méthode de calcul est employée, mais la répartition de pression à la paroi est celle correspondant à un écoulement de révolution à potentiel, obtenue à partir de mesures à la cuve rhéoélectrique. Cette répartition est plus proche de la réalité.

L'épaisseur de déplacement de la couche limite est un peu plus élevée que pour l'écoulement par tranches parallèles et par conséquent le coefficient de débit est un peu plus faible. Les écarts restent minimes.
The concept of a mean temperature in the flame reaction zone
Authors: Van Tiggelen P. J. , Duval A.
Published: April 2023

The flame reaction zone can be assimilated to a homogeneous reactor provided appropriate mean values of the temperature, the diffusion coefficient and the reaction rate are defined. This problem makes the object of this paper and proper values are tabulated. Methods are proposed in order to obtain overall kinetical parameters (activation energy and reaction order) from experimental measurements of burning velocity, flame temperature and flame front thickness.
Kinetical study of hydrogen-nitrous oxide flames
Authors: Duval A. , Van Tiggelen P. J.
Published: April 2023

Flames propagating in hydrogen-nitrous oxide mixtures have been investigated in widely varying conditions of competition and dilution with different inert gases. The kinetical interpretation of the experimental values, obtained for burning velocities, the flame temperatures and the flame front thicknesses, leads to a branching process involving a collision between an excited OH radical and a hydrogen molecule. The overall activation energy is found to be 26.5 kcal/mole and the overall reaction order with respect to the initial species is equal to two.

The effect of temperature on Stokes drag
Authors: Avudainayagam Ambal , Venkatarangan S. N.
Published: April 2023

The variational principle given by Glansdorff and Prigogine for slow viscous flow at non-uniform temperature is used to obtain a first approximation to (i) the drag on a slowly moving sphere and (ii) the torque on a rotating sphere in an unbounded liquid. The results are compared with the work of Hays in which the shear stress in the case of Couette flow between parallel walls maintained at constant temperature is calculated.

Irreversibility in paramagnetic spin systems : The double resonance processes. (II)
Authors: Walgraef D.
Published: April 2023

In a preceding paper, the author derived kinetic equations describing the time evolution of the density matrix of a paramagnetic spin system on which a double resonance process is performed. It is shown here that these equations may be numerically solved without any phenomenological assumptions on the quantities they involve and are able to describe quantitatively the results of the double resonance experiments.
Mathematical foundations of non-equilibrium statistical mechanics. II. Perturbation theory
Authors: Rae John
Published: April 2023

Working within the formalism developed by Professor I. Prigogine and his coworkers, this paper examines both the perturbation series obtained by iterating the resolvent equation and the irreducible operators introduced by this means. It is shown that the series can be regarded as asymptotic in a certain sense but that this interpretation is not useful for long time behaviour. Instead of performing the usual resummation of the series it is shown that the irreducible operators can be defined in an entirely rigorous way independent of the series expansion. The advantages of this approach and its connection with the usual procedure are pointed out.

Le théâtre liégeois de Jean-Noël Hamal, feu d'artifice ou comète périodique ?
Authors: Quitin José
Published: April 2023

The Liegeois Theater is a set of four operas composed in 1757-1758 by Jean-Noël Hamal (Liège 1709-1778), singing master at the Liege Cathedral, on libretti in Walloon dialect due to four aristocrats of the country. They took the operas buffas in Napolitan dialect by Pergolesi and Latilla as models, but introduced into them such modern tendencies as truthfulness, naturalness, actuality of theme called by Diderot for the French theater about 1750.

Faithful to his Italian patterns, Hamal uses recitativo secco, aria da capo and ensembles at the end of an act, all of them being accompanied by a simple string quartet. On occasion pastiches of Parisian sentimental songs and ariettes, but also real tunes in the French fashion are inserted into the theatrical action.

The success of the Liegois Theater was abruptly annihilated by that of the new opera with spoken dialogue precisely in 1769 after the first performance in liège of Le Huron by Grétry (Liège 1741-Montmorency 1813). Yet, just like a recurrent comet, it reappears on playbills for the greatest enjoyment of those who love the lyrical dialect theater.
Le patrimoine architectural : enjeu du défi de l'ère post-industrielle

Published: April 2023

Putting an end to this era of pollution and enslavement in human history and successfully bringing the worlds of computer science and craftsmanship to live together in perfect harmony - those two poles of technology being equally indispensable to the quality of human life - this is definitely our challenge for the future.

The architectural and urbanistic heritage is thoroughly involved in this challenge. It is essential to protect it and to adapt it to our times in order to prepare a world which will again aspire to foster that extraordinary asset for the human species which the diversity of its cultures and the impressive extent of its geographical features represent.
Les fonts baptismaux de Saint-Barthélémy à Liège. Une merveille, des problèmes. Propositions pour le soubassement
Authors: Colman Pierre
Published: April 2023

One of Belgium's «seven marvels», the baptismal font in St-Bartholomew's church in Liège has been claimed the most beautiful in the world. It has been at the center of a heated debate since 1984 : is it the masterpiece produced by a Mosan goldsmith, Renier de Huy, between 1107 and 1118, as has generally been thought for many years ? or was it cast in the end of the tenth century in Byzantium ? The controversy is in progress. Problems are meanwhile being raised about the pedestal, which originally had twelve oxen, like the «brazen sea» of king Solomon, but which nowadays has only ten left, with parts of legs quite severely damaged. Various improvements are being proposed.
Ania Staritsky et la poésie partagée
Authors: Roberts-Jones Philippe
Published: April 2023

A substantial part of the work of Russian-born painter and engraver Ania Staritsky (1908-1981), who worked in Brussels before moving to Paris, is devoted to painting-poems, object-poems and book-poems. This marriage of text and painting is part of a tradition which certainly goes back to Francis Picabia, and whose exponents in French-speaking Belgium are de Broodthaers, Alechinsky and Lacomblez. Playing with paint, collage, engraving and writing, Ania Staritsky's work in this area offers a very personal vision. The artist's texts are chosen from contemporary poets, including Michel Butor, Gaston Puel, Philippe Jones and Jean-Clarence Lambert.
Peuples et lieux imaginaires
Authors: De Keyser Eugénie
Published: April 2023

Sculptors at the end of our century have attempted, like A. Giacometti before them, to make spaces and places directly evoke imaginary people or forgotten legends. These surface from specific materials charged with symbols : earth for Charles Simonds's little people, coal and gold for the hidden cities and archetypes of Anne and Patrick Poirier, leafs, twigs and bits of bark for Jephan de Villers' people of Arbonie. Supporting them, each of these artists creates an imaginary history with invented texts, stories, or indecipherable writings, which feed our belief in strange and forgotten civilizations.
La phénoménologie de la création artistique selon Cesare Brandi
Authors: Philippot Paul
Published: April 2023

Cesar Brandi (1906-1988), whose work is currently being republished in Italy, developed, from 1945 onwards, a phenomenology of artistic creation envisaged, not from the usual viewpoint of the viewer, but from that of the creative act, and shaped by the particular nature of the different art forms. During the 1950s, this original approach encounters structuralist currents, which it exploits and integrates in a very personal fashion. The main lines of this theoretical development, inseparable from Brandi's profession of art historian, in which he reveals his fecundity, is retraced in this contribution.
Franz Liszt, un virtuose «mal assis»
Authors: Wangermée Robert
Published: April 2023

The 1830s were a golden age of instrumental virtuosity. With the end of the Ancien Régime, musicians -composers and players alike - were no longer the paid servants of princes or the Church. They had acquired their freedom, but the need to earn a living often led them to produce music which pandered to the tastes of an audience which now included new layers of the bourgeoisie, and to sell it like merchandise.

Franz Liszt, one of the most illustrious of these virtuosi, was torn between the desire to affirm himself as the greatest virtuoso of his day and the wish to win recognition from the intelligentsia of philosophers, poets, painters and innovative composers (Berlioz, Schumann,...) as a successor to Beethoven.

His «cultural» aspirations are expressed in several series of articles inspired variously by Saint-Simon, Lamennais and Ballanche. In them, he presents a lucid criticism of the musical institutions, the lyrical theatres, concerts and music teaching of his time, and sets out proposals for reform.

What is ambiguous in Liszt's attitude is that, for all this, he did not renounce his ambitions as a piano athlete. These contratst did not fail to strike lucid minds, provoking in particular the irony of Heinrich Heine, who saw in him a pianist "badly seated" between contradictory options, and ill at ease with his success as a virtuoso. It was only from 1847 onwards, as Kapellmeister of the Duke of Weimar, that Liszt escaped form the temptations of commercializing his art. However, with artists having lost their clearly defined social function, he was no longer a paid musician-servant as under the Ancien Régime.

From that time on, it was clear that music which wanted to escape from market constraints could survive only by subsidies and support from public or private benefactors. 1847 onwards, as Kapellmeister of the Duke of Weimar, that Liszt escaped form the temptations of commercializing his art.

Franz Liszt au Pays de Liège
Authors: Quitin José
Published: April 2023

Combining information from Liszt's correspondence and contemporary newspapers, Quitin shows the virtuoso leaving to conquer Belgium in 1841. Quitin accords particular attention to Franz Liszt's «Liège» performances of 13, 19 and 24 February and 11 October 1841, and of 17 and 20 July 1842 (inauguration of the statue of Grétry), to his performance at Spa on 20 August 1845 (on his way back from the inauguration of the Beethoven monument in Bonn on 15 August), and his unscheduled participation on 28 January 1846 at the Liège Musical Society's charity concert. The difficulties aroused by the practical organization of these concerts and the reactions of the audience and of Liszt himself are evoked in a number of often unpublished documents. Similarly, in the programmes, we perceive the evolution of the virtuoso's musical concepts shortly before setting up in Weimar.

Franz Liszt was not to return to Liège until 40 years later, to attend a monumental concert of his work offered to him by the Société Libre d'Émulation on 27 March 1886, and conducted by Eugène Hutoy (Liège 1844-1889). The triumphantly successful performance of his Messe de Gran was a prelude to its triumph in Paris on 25 March. 17 and 20 July 1842 (inauguration of the statue of Grétry), to his performance at Spa on 20 August 1845 (on his way back from the inauguration of the Beethoven monument in Bonn on 15 August), and his unscheduled participation on 28 January 1846 at the Liège Musical Society's charity concert.

Les cent cinquante ans de la Classe des Beaux-Arts
Authors: Colman Pierre
Published: April 2023

The President of the Academie thanks their Majesties the King and the Queen for their presence today. He reminds those present that the King is the Protector of the Academie.

The anniversary which we are celebrating today is not that of the creation of this venerable institution, but that of its reorganization, when the Fine Arts class was added to those of Science and of Literature.

The balance sheet of 150 years of activity by the class whose anniversary we are celebrating is an attractive one. Its members have included Adolphe Quételet, the Leonardo da Vinci of the Jeune Belgique movement, James Ensor and Paul Delvaux, to mention just three. It has published abundantly, including the catalogues of two memorable exhibitions. It is benefited from the gifts of a host of benefactors. It has awarded a quantity of prizes and subsidies.

The whole Académie is very concerned to preserve its independence vis-à-vis the powers which command this world. In all circumstances it upholds intelligence, sensitivity and creativity, the cult of Truth, Beauty and Goodness. Its vocation is to reward merit. It is resolutely elitist, but in no ways haughty. It is not afraid to descend into the arena. The palace in which it lives is a large house of noble appearance, but it is no ivory tower, no fortress. Symbolically it bears comparison with a lighthouse.
Mémoire et visibilité : la construction symbolique de l’espace en Grèce géométrique

Published: April 2023

En Grèce géométrique, l’espace est beaucoup plus différencié et construit que ne pourrait le laisser croire une analyse en termes de public et de privé : l’articulation entre mémoire et visibilité, entre rite et signe, que l’on décèle dans plusieurs exemples de pratiques et d’aménagements funéraires, permet d’identifier les lieux d’élaboration d’identités collectives, associés à différents modes et différents contextes de commémoration.
Les en-têtes de décrets à relief à Athènes : entre consécration privée et pratique publique
Authors: Marc Jean-Yves
Published: April 2023

Les stèles inscrites à relief, qui participent à la fois de l’épigraphie par le texte gravé et de l’archéologie par le relief, combinent une décision officielle et une initiative privée. Ces documents, qui attestent une volonté de témoigner solennellement d’un succès devant l’assemblée, sont à placer dans le contexte de la vie politique athénienne, où, les fonctions électives étant très peu nombreuses, la légitimité des dirigeants ne peut guère se constituer que grâce aux succès remportées devant les assemblées délibérantes. Ces stèles relèvent ainsi d’une analyse de nature politique, puisqu’elles procèdent de ce régime si particulier de l’Athènes classique, mélange de démocratie directe, par le rôle essentiel qu’y jouent des assemblées, et de démocratie gouvernée, par la prééminence d’une classe d’orateurs.
La cité, les particuliers et les terres : installations ou retours de citoyens en Grèce archaïque
Authors: Ruzé Françoise
Published: April 2023

Lorsque la jouissance d’un lot de terre est tenue pour nécessaire à la survie du citoyen et au maintien d’une base de recrutement hoplitique, comment satisfaire les besoins des nouveaux colons qui viennent s’installer, des colons malchanceux qui reviennent dans leur cité d’origine, des bannis qu’une réconciliation autorise à rentrer ? À défaut de réserve foncière, la cité doit donc, selon les cas, amputer les terres des populations environnantes, imposer aux familles demeurées sur place de réserver durant quelques années la part du colon, faire admettre une jouissance conditionnelle des terres des exilés afin qu’elles puissent leur être restituées. Les textes épigraphiques permettent de suivre certaines des mesures prises à cet effet et nous confortent dans l’idée que la jouissance d’une terre était beaucoup plus importante que sa possession.
Overall agreement between eGFR estimates obtained with the CKDEPI, MDRD and CG formulae in patients with advanced HIV diseases
Authors: Vu Quoc Dat , Nguyen Dinh Hong Phuc , Ba Dinh Thang
Published: April 2023

Background: Traditional CKD risk factors as well as HIV-related factors are major determinants of the prevalence of renal diseases among HIV patients. Few equations have been used in clinical practice for calculating creatinine clearance, however, the accuracy of these formulae in HIV patients has been different. Our goal was to evaluate the reliability of all three equations (Chronic Kidney Disease Epidemiology Collaboration, Modification of Diet in Renal Disease, and Cockcroft-Gault) to estimate GFR in HIV-infected patients. Materials and method: We conduct a retrospective, observational cohort study of patients with
HIV infection who are first time in care at selected HIV OPCs in Vietnam. Results: In 1108 patients eligible for analysis, a major patient was in HIV clinical stage 3 and 4 with a median age of 36, and median serum creatinine of 0.89 mg/dL. eGFR calculated by CG equation was lower than CKD-EPI formulae in overall except overweight patients (p<0.05, paired t-test) while the similar results were observed in both CKD-EPI and MRDR (p=0.144, paired t-test). Conclusion: There was a substantial agreement between CKD-EPI and MDRD eGFR, agreement percentage of 90.1 and MDRD was reliable as CKD-EPI to calculate eGFR in the HIV population.
Key words: HIV, eGFR, CKD-EPI, MRDR, CG.
Living Chinese Herbal Scaffolds from Microfluidic Bioprinting for Wound Healing
Authors: Wang Xiaocheng , Jia Jinxuan , Niu Mengying , Li Wenzhao , Zhao Yuanjin
Published: April 2023

Biological scaffolds have been widely employed in wound healing applications, while their practical efficiency is compromised by insufficient oxygen delivery to the 3-dimensional constructs and inadequate nutrient supply for the long-term healing process. Here, we present an innovative living Chinese herbal scaffold to provide a sustainable oxygen and nutrient supply for promoting wound healing. Through a facile microfluidic bioprinting strategy, a traditional Chinese herbal medicine (Panax notoginsengsaponins [PNS]) and a living autotrophic microorganism (microalgaeChlorella pyrenoidosa[MA]) were successfully encapsulated into the scaffolds. The encapsulated PNS could be gradually released from the scaffolds, which promoted cell adhesion, proliferation, migration, and tube formation in vitro. In addition, benefiting from the photosynthetic oxygenation of the alive MA, the obtained scaffolds would produce sustainable oxygen under light illumination, exerting a protective effect against hypoxia-induced cell death. Based on these features, we have demonstrated through in vivo experiments that these living Chinese herbal scaffolds could efficiently alleviate local hypoxia, enhance angiogenesis, and thereby accelerate wound closure in diabetic mice, indicating their great potential in wound healing and other tissue repair applications.
Unimolecular Reactions of
E
-Glycolaldehyde Oxide and Its Reactions with One and Two Water Molecules
Authors: Sun Yan , Long Bo , Truhlar Donald G.
Published: April 2023

The kinetics of Criegee intermediates are important for atmospheric modeling. However, the quantitative kinetics of Criegee intermediates are still very limited, especially for those with hydroxy groups. Here, we calculate rate constants for the unimolecular reaction of
E
-glycolaldehyde oxide [
E
-hydroxyethanal oxide,
E
-(CH
2
OH)CHOO], for its reactions with H
2
O and (H
2
O)
2
, and for the reaction of the
E
-(CH
2
OH)CHOO…H
2
O complex with H
2
O. For the highest level of electronic structure, we use W3X-L//CCSD(T)-F12a/cc-pVDZ-F12 for the unimolecular reaction and the reaction with water and W3X-L//DF-CCSD(T)-F12b/jun-cc-pVDZ for the reaction with 2 water molecules. For the dynamics, we use a dual-level strategy that combines conventional transition state theory with the highest level of electronic structure and multistructural canonical variational transition state theory with small-curvature tunneling with a validated density functional for the electronic structure. This dynamical treatment includes high-frequency anharmonicity, torsional anharmonicity, recrossing effects, and tunneling. We find that the unimolecular reaction of
E
-(CH
2
OH)CHOO depends on both temperature and pressure. The calculated results show that
E
-(CH
2
OH)CHOO…H
2
O + H
2
O is the dominant entrance channel, while previous investigations only considered Criegee intermediates + (H
2
O)
2
. In addition, we find that the atmospheric lifetime of
E
-(CH
2
OH)CHOO with respect to 2 water molecules is particularly short with a value of 1.71 × 10
−6
s at 0 km, which is about 2 orders of magnitude shorter than those usually assumed for Criegee intermediate reactions with water dimer. We also find that the OH group in
E
-(CH
2
OH)CHOO enhances its reactivity.

Limitations of LGBTQ+ Symbol Inclusion and Iconicity in "Functional" AAC
Authors: Chodos Carson
Published: April 2023

Carson Chodos offers commentary on the inherent limitations of reformist cis imagination and resulting education policy and linguistic failures. Specifically within a project to create LGBTQ+ inclusive symbol iconicity for students with disabilities that primarily utilize AAC (augmentative and alternative communication) systems. Carson Chodos, a public school teacher (a cisgender lesbian), reflects on (mis)applications of limited functional communication systems on her students. Directly participating in the positioning of students as both innocent victims and responsible neoliberal subjects for the tolerant liberal state, she initiated a special project through the Division of Specialized Education and Student Support to create inclusive symbolic vocabulary reflective of the realities of the students with disabilities she worked with. Until 2019 there was an incredible absence of all symbols within the core vocabulary packages that excluded LGBTQ+ identities, families, relationships, or gender expressions.  Since her initial project, there are now a few ad hoc library banks of LGBTQ+ icons across proprietary AAC software programs. This is not a success but, instead, a call for decentralized, evolving vocabulary to reflect the queer relational understandings of disability and participatory languaging.

ZYNOVIY BYCHKO ABOUT THE UKRAINIAN LANGUAGE
Authors: Hlukhovtseva K.
Published: April 2023

This article discusses the problems raised in the aphorisms of Zynoviy Bychko who is an Ukrainian dialectologist, linguist, professor of Lviv Ivan Franko National University, member of the Ukrainian National Union of Journalists, member of the Shevchenko Scientific Society, member of UIA. He identifies the main means of imagery, focuses on the vitality of the Ukrainian language, which the scientist has repeatedly violated. Analysis of the material was carried out by a descriptive method using elements of analysis of scientific sources.
The authors emphasize that Zynoviy Bychko’s aphorisms are primarily educational in nature. Taking care of the accessibility, general understanding and imagery of his catchphrases, the author often resorts to the use of transparent analogies that help to comprehend the essence of such difficult concepts as language, word, genetic code. He compares language with an icon, space, galaxy, building structures, works of art, women's jewelries, the human nerve, concrete and abstract concepts, which helps to show the complexity and simplicity of speech. The author endows the lexemes of the language and the word with numerous epithets, creates a phytocharter of the Ukrainian alphabet, which convinces of the beauty and richness of the Ukrainian language.
Zynoviy Bychko, taking care of the vitality of speech, with vivid examples shows the antiquity of archetypal symbols, the beauty of the poetic word and the perniciousness of speech, distorted by surzhyk and slang, barbarisms. Based on the research of geneticists, physicians, convinces of the harmfulness to the moral and physical health of a person of the negative energy that obscene vocabulary produces.
The issues of purity, aesthetics, ecology of personality speech are urgent problems, they should be solved professionally and persistently, despite the resistance of opponents. The prosperity of the language, the expansion of its information space is a question of the Ukrainian survival in Ukraine, it is a question of state independence and individual freedom.

Lead tri-halide perovskite quantum dots (PeQDs) have attracted attention as a light source such as LEDs. However, this causes a decrease in not only their dispersibility but also photoluminescence quantum yield (PLQY), which is one of the factors for external quantum efficiency (EQE) of LEDs when the ligand as an insulating component is removed. Herein, we proposed a strategy to prepare PeQDs, which selectively coordinated potassium oleate on the surface of PeQDs. As a result, PeQDs were successfully prepared, while maintaining the dispersibility and high PLQY after removing the ligands and achieving improved EQE.

Authors: Limna Pongsakorn
Published: April 2023

This review article aimed to assess the existing literature regarding the digital transformation of healthcare in the digital economy. The review employed narrative synthesis. Moreover, this systematic review made use of a number of databases, including EBSCO, Google Scholar, Scopus, Web of Science, and ScienceDirect. The documentary method and content analysis were used via systematic review to analyze the data. The review of literature suggested that digital technologies have the potential to improve healthcare delivery, enhance patient outcomes, and increase access to healthcare services. The studies reviewed in this article demonstrate that digital transformation in healthcare can lead to improved efficiency, reduced costs, increased patient satisfaction, and better patient outcomes. The use of digital technologies such as telemedicine, electronic health records, wearables, and mobile health applications has already started to revolutionize healthcare delivery. However, the adoption of these technologies is not without its challenges, including privacy and security concerns, regulatory barriers, and resistance from healthcare providers. It is therefore important for healthcare organizations and policymakers to address these challenges and implement strategies to ensure the effective integration of digital technologies into the healthcare system. Overall, the findings suggest that the digital transformation of healthcare is a critical area of research that has the potential to significantly transform the healthcare industry and improve health outcomes for individuals and communities.
Il paroliere è un poeta, non un parolaio!

Published: April 2023

È giunta da qualche giorno al nostro presidente Marazzini la seguente richiesta, da parte della SIAE (Società Italiana degli Autori ed Editori): Gentilissimo Presidente, come accennatole stamattina e su indicazione del nostro Presidente onorario Giulio Rapetti Mogol, vorremmo avere dall’Accademia della Crusca una consulenza sul termine paroliere, usato spesso in maniera colloquiale come sinonimo della parola autore. Come le abbiamo spiegato, per il nostro Presidente utilizzare questo vocabolo equivale a sminuire la portata di un’attività creativa e artistica tra le più nobili ma saremmo onorati di avere anche la vostra opinione in merito. Tale richiesta si aggiunge a quella, pervenutaci vario tempo fa, di un lettore che voleva “sapere quando e come entra in uso la parola paroliere per indicare colui che scrive il testo di una canzone”.

Introduction: Adolescents and young adults are high-risk groups for skin and sexually transmitted diseases, especially in developing or lowincome countries. The present study was conducted to give an insight on the various dermatological and sexually transmitted diseases in
adolescents and young adults in the age group of 10-24 years. Materials and Methods: This is a retrospective study where all the records of the
patients who presented at a speciality clinic for adolescents and young adults were assessed. Those patients who consulted the treating
dermatologist were included in the study. The records of 422 patients between the ages of 10 and 24 years, attending the tertiary care centre in
Eastern Uttar Pradesh during 2020 and 2021 were included in this retrospective study. Results: Out of 422 patients, there were 164 males and 258
females. The mean age of all patients was found 19.433.57 years. The most common dermatological disease was Dermatophytic fungal infections
seen in 67(15.8%) patients followed by chronic Idiopathic Urticaria in 57(13.5 %) patients followed by acne Vulgaris in 46(10.9%) patients.
Among infestations, Scabies was seen in 41 (9.7%) patients. The next common dermatoses were Post Inammatory Hyperpigmentation seen in 40
patients. In hair disorders, telogen efuvium was the most common manifestation seen in 39(9.2%) patients. Among sexually transmitted
infections (STI), Vulvovaginal Candidiasis was diagnosed in 19 patients and genital warts in one male patient. Conclusion: Fungal infections are
common in adolescents and young adults. Acne Vulgaris is also common in this age group

Introduction: Anterior cruciate ligaments (ACL) Reconstruction have undergone series of evolution over the past 30 years to improve the
biomechanics of knee joint. In 1970's surgery was done to repaire the torn ends of the ligaments. After that, repaire of ACLusing auto graft was done
in 1980's using arthrotomy (open procedure). Aims: To compare between Patellar tendon graft and Hamstring graft in arthroscopic ACL
reconstruction on the basis of clinical and functional outcome. Materials and Methods: The present study was an Institutional based analytical
epidemiological study with longitudinal design study. This Study was conducted from 12 months at Department of Orthopedics, Bankura
Sammilani Medical College and Bankura. Result:In our study, We have studied 40 cases of ACLtear, amongst the 20 cases operated by Hamstring
graft, 3(30%) patients were found to have ACLtear on the right side and 7(70%) were found to have tear on left side. Amongst the 20 cases operated
by bone patellar tendon, 6(60%) were found to have right sided tear and 4(40%) were found to have left sided tear. Conclusion: We found that,
mechanical advantage rests with the bone patellar tendon as in previous studies the bone to bone integration is much better when compared to
hamstring grafts. Micheal Hnuesstated in this study that the bone patellar tendon has higher post operative activity levels than hamstring grafts.
ANGIOMYOLIPOMA – VARIED PRESENTATIONS – A CASE SERIES
Authors: Gnanasekaran T , Prabakaran P , Induja J , M Dhinesh A
Published: April 2023

Renal angiomyolipoma is a benign mesenchymal tumour composed of fat cells, smooth muscle cells, and thick-walled blood vessels. These tumors
can occur sporadically or as part of genetic syndromes: most commonly tuberous sclerosis complex. Here we present three cases of Renal
angiomyolipoma(AML) in different scenarios - presenting with clinical features like ank pain, abdominal mass or perirenal haematoma with
hypovolemic shock. All three cases were evaluated by contrast enhanced CT & diagnosed as renal angiomyolipoma. Nephron sparing surgery -
Partial nephrectomy was done in case 1. Case 2 underwent angiography with non- selective angioembolisation preoperatively followed by simple
nephrectomy. Case 3, after initial stabilization and evaluation found to be a case of Wunderlich syndrome and simple nephrectomy done. Post
intervention period was uneventful for all 3 cases. In the 6-month follow-up, all three patients were doing well with normal renal function and no
recurrence in case of partial nephrectomy. Embolisation is the emergency treatment of choice for bleeding angiomyolipoma. Whenever possible, a
nephron sparing approach by either transarterial embolisation or partial nephrectomy is to be considered. In cases of angiomyolipoma of both
kidneys or in a solitary functioning kidney, renal preservation is mandatory in order to avoid need for renal replacement therapy. Also, recently
approved drug Everolimus may be considered for patients not suitable for surgery particularly in tumour seen with tuberous sclerosis
