Administración desleal, malversación y enriquecimiento ilícito (Reflexiones a propósito de la Ley Orgánica 14/2022, de 22 de diciembre)
Authors: Jaén Vallejo Manuel
Published: June 2023

La reforma de la Ley Orgánica 1/2015 introdujo en el Código Penal una regulación moderna de la administración desleal, tanto de patrimonio privado como de patrimonio público. La nueva regulación de la malversación introducida por la Ley Orgánica 14/2022 ha introducido tres niveles de malversación: el tipo básico de la apropiación de fondos, acción que debe llevarse a cabo con ánimo de lucro, algo que debería ser irrelevante, pues no es un delito de enriquecimiento, sino de daño, y sin mención alguna a la administración desleal de esos fondos públicos; y dos tipos atenuados de administración desleal de patrimonio público, limitados al uso temporal de bienes públicos sin animus rem sibi habendi y al desvío presupuestario. También introduce esta reforma en el Código Penal el delito de enriquecimiento ilícito, salvando la crítica de ser un «delito de sospecha» a través de su configuración como delito de desobediencia.
Conductas reparadoras - Derecho penal - Ordenamiento jurídico italiano
Authors: Bernasconi Costanza
Published: June 2023

El artículo tiene como objetivo analizar los diferentes modelos de interacción entre las conductas restaurativas y la responsabilidad penal en el ordenamiento jurídico italiano. De hecho, en las últimas décadas, el legislador italiano ha recurrido cada vez más a disposiciones destinadas a atribuir importancia, en diversas formas, a las conductas de reparación post delictum. Estas previsiones se inspiran, sin embargo, en lógicas y objetivos político-criminales no siempre homogéneos, ya que son capaces de satisfacer diferentes demandas y de asumir múltiples formas jurídicas. Por lo tanto, este trabajo tiene como objeto definir un marco sistemático global, poniendo de relieve las características y los principales problemas de cada modelo.
Inscribed versus Invoked Attitudes: Appraisal Among Indonesian Teenagers in English Captions on Instagram
Authors: Himmawati Dian Rivia , Munandar Aris , Sajarwa Sajarwa
Published: June 2023

On Instagram, Teenagers’ captions in English do not always describe the picture but symbolically express their feelings to their friends as a whole.  In this case, English captions enhance status and authority and reveal the attitudinal evaluation related to feelings and values. This paper aims to discuss the self-presentation between Indonesian female and male teenagers on their emotional, critical and evaluative stance reflecting on English captions on Instagram when the captions talk about friends and their relationship. Appraisal theory proposed by Martin and White to reveal the attitudinal evaluation is applied in this study. From 500 English captions, 90 captions deal with 155 appraising items about friends. They are 112 female appraised items and 43 male appraised items. Caption's screenshots are used to collect the data. The invoked attitude data are coded by examining posted photos.  The result of the research is (1) male and female teenagers prefer to express their attitude by using inscribed attitude rather than invoked attitude, (2) male teenagers expresses moreattitude through Affect, while female teenagers express more through Judgment, (3) negative appraisal is to used to emphasize the positive values  in the form of a counter concession, for male teenagers to highlight togetherness, while for female teenagers are more focused on empathy, (4)  both female teenagers and male teenagers use negation to show a positive attitude related to judgment propriety (ethical Judgment).  Therefore, writing captions on Instagram provide an opportunity for male and female teenagers to express their attitudes as they imagine to show their strength without physically confronting the interlocutor.
A corpus linguistic study of constructional equivalence for the Indonesian translation of ROB and STEAL based on the OpenSubtitles Parallel Corpus
Authors: Rajeg Gede Primahadi Wijaya , Rajeg I Made
Published: June 2023

Catford’s (1965) classic idea in translation theory indicates the measurability of translation equivalence. Following up on this idea, this paper offers a case study to measure the translation equivalence of English verbal near-synonyms ROB and STEAL (R&S), especially the equivalence at the constructional level. Adopting a quantitative corpus linguistic method and the Construction Grammar approach, we analyse random usage samples of R&S from English-Indonesian parallel corpus for the degree of constructional equivalence along two dimensions: (i) the profiled participant roles and (ii) the grammatical construction types of these verbs. We discover that the Indonesian translations maintain a high degree of equivalences along these dimensions, albeit with few variations. This suggests that the translators attempt to be as faithful as possible to the source texts. Furthermore, our study reveals the translation norms/typicality in how the constructional profiles of the near-synonyms R&S are translated into Indonesian. The paper generally seeks to demonstrate how such a central notion as equivalence in translation studies can be investigated using parallel corpora and the quantitative corpus linguistic method.
Capillary Schwarz symmetrization in the half-space
Authors: Lu Zheng , Xia Chao , Zhang Xuwen
Published: June 2023

In this article, we introduce a notion of capillary Schwarz symmetrization in the half-space. It can be viewed as the counterpart of the classical Schwarz symmetrization in the framework of capillary problem in the half-space. A key ingredient is a special anisotropic gauge, which enables us to transform the capillary symmetrization to the convex symmetrization introduced in Alvino et al.https:/doi.org/10.1016/S0294-1449(97)80147-3.
The portrayal of women in Jordanian proverbial expressions: A thematic analysis
Authors: Al Rousan Rafat Mahmoud , Shatnawi Hadeel Nidal
Published: June 2023

Proverbial expressions are linguistic elements that represent the images and values of a society. This study examines the portrayal of women in Jordanian proverbial expressions. It attempts to answer the following question: How are women portrayed in Jordanian folk proverbs? To this end, seventy-eight Jordanian proverbs related to women were collected through interviews and from published folklore books. Employing thematic analysis, the data were classified into eight categories, namely, women as wives, unmarried women, women as mothers, women as daughters, widowed women, divorced women, women as relatives-in-law and women in general. The analysis also shows that women are represented both negatively and positively in all categories. However, the negative image of women depicted in the proverbs exceeds the positive one. Based on the conclusions, some future research was suggested.
Cerebral asymmetries in the processing of opaque compounds in L1 Polish and L2 English
Authors: Hwaszcz Krzysztof , Kędzierska Hanna
Published: June 2023

We report the results of a cross-modal priming study investigating the processing of opaque compound words, when followed by figuratively and literally related primes, in L1 (Polish) and L2 (English). Additionally, the half-divided visual field paradigm was used to verify which cerebral hemisphere is responsible for semantic decomposition, and whether the language status will lead to different activation patterns. The left hemisphere is generally believed to process the more salient or conventional meanings of figurative expressions, and the right hemisphere their less salient or unconventional meanings. However, this assumption has not so far been verified for compounds. The results suggest that both the figurative and the literal meanings of opaque compounds were processed significantly faster by the left hemisphere in the case of L1 Polish. No statistically significant differences were obtained for L2 English. At the same time, English compounds were overall processed significantly faster than Polish compounds.

Vitamin C and epigenetics: A short physiological overview
Authors: Pavlovic Voja , Ciric Milan , Petkovic Milan , Golubovic Mladjan
Published: June 2023

In recent years, ascorbic acid (vitamin C) has acquired great interest due to its multiple functions, which results in homeostasis of normal tissues and organs. On the other hand, it has been shown that epigenetic modifications may have an important role in various diseases and therefore are a focus of the extraordinary investigation. Ascorbic acid serves as a cofactor for ten-eleven translocation dioxygenases, which are responsible for deoxyribonucleic acid methylation. Also, vitamin C is required for histone demethylation, since it acts as a cofactor of Jumonji C-domain-containing histone demethylases. It seems that vitamin C may be a mediator between the environment and the genome. The precise and multistep mechanism of ascorbic acid in epigenetic control is still not definitely determined. This article intends to provide the basic and newly discovered functions of vitamin C that are related to epigenetic control. Also, this article will help us to better understand the functions of ascorbic acid and will provide the possible implications of this vitamin in the regulation of epigenetic modifications.
Parua magnis: Die Villenbeschreibungen des jüngeren Plinius im intertextuellen Größenvergleich (epistulae 2,17 und 5,6)
Authors: Beer Beate
Published: June 2023

Despite the frequent use of the antithesis of parua and magna in Latin literature, the expression parua magnis in Pliny 5,6,43–44 need not be read as proverbial but as a quotation of Vergil, georg. 4,176. This attribution follows from the naming of Vergil and of Aratus in epist. 5,6,43–44. Combined allusions as in 5,6,43–44, consisting of a quotation, the naming of the author and/or narrative structures, are a pattern in the corpus of the younger Pliny’s correspondence. The context of georg. 4,169–179, too, supports the attribution of the phrase as a quotation, since in Vergil’s lines a comparison of genres is made, which Pliny adopts for his own literary positioning in the descriptions of villas in epist. 2,17 und 5,6. Further, the attribution to Vergil’s didactic poem, in combination with the reference to Aratus, which other interpretations hardly take into account, permits a new understanding of the narrative structure of the villa descriptions and their allusive affinity not only to ecphrasis but also to didactic poetry.
Was the Commentary on Vergil by Aelius Donatus Extant in the Ninth Century? A Reappraisal
Authors: Danovi Vittorio Remo
Published: June 2023

That the Vergilian commentary by Aelius Donatus – one of the most influential late-antique commentaries that have not survived – was extant in the ninth century and available to some Carolingian scholars is still a widespread belief. The evidence in support of this thesis is said to have been provided by the Harvard Servianist J. J. H. Savage in three articles published between 1925 and 1931. In these articles, Savage claimed that a few marginal notes in one of the ninth-century primary witnesses to the DS scholia, the so-called ‘Vergil of Tours’ (Bern, Burgerbibliothek, Ms. 165), were drawn almost directly from Donatus’ commentary and that a marginal note in a roughly coeval Servian witness (Bern, Burgerbibliothek, Ms. 363) provided information about a place where a copy of the commentary could be found. A re-examination of the two manuscripts shows that the evidence adduced by Savage does not stand scrutiny and that the terminus post quem for the loss of Donatus’ commentary should be antedated by at least one century.
The Social Networking Function of Cicero’s Prefaces to the Philosophical Works
Authors: Dowson Christopher
Published: June 2023

The value of theprohoemiaor ‘prefaces’ to Cicero’s later philosophical works, composed in the last years of his life, has not yet been settled. Two schools of thought have emerged somewhat more clearly in recent times: one places a greater value on the prefaces as tools for understanding Cicero’sphilosophicaas a whole, the other applies a more skeptical approach, using a degree of caution as to the nexus between the prefaces and the treatises to which they were affixed. The article advocates for the latter camp, however not only to temper the recent emphasis the optimists have placed on the prefaces as key interpretive elements to the dialogues, but to refocus their importance as extensions of Cicero’s personal and social networking with other Roman elites of his time. I rely on two main lines of argument: the anecdotal evidence from Cicero’svolumen prohoemiorum, “book of prefaces”, mentioned in a letter to Atticus in 44bce, as well as a broader analysis of a deeper disconnect between Cicero’s prefatory rhetoric regarding Latin philosophical vocabulary compared with Greek and his translation practices in his treatises.
Relationship of thrombospondin-1 and thrombospondin-2 with hematological, biochemical and inflammatory markers in COVID-19 patients
Authors: Dogan Serdar , Okuyan Hamza Malik , Bal Tayibe , Çabalak Mehmet , Begen Mehmet A.
Published: June 2023

Objectives

Roles of thrombospondin-1 (TSP-1) and thrombospondin-2 (TSP-2) in tissue repair and inflammation are well-documented, but the association of their serum expressions with the pathogenesis of COVID-19 remains unclear. We investigate the roles of TSP-1 and TSP-2 in COVID-19.

Methods

106 SARS-CoV-2 infected patients and 23 healthy people were enrolled in our study. COVID-19 patients were divided into two groups as non-severe and severe. TSP-1 and TSP-2 concentrations were measured with an enzyme-linked Immunosorbent Assay, and blood markers were analyzed with routine laboratory techniques.

Results

COVID-19 patients had significantly higher TSP-1 and TSP-2 levels than healthy controls. TSP-1 and TSP-2 positively correlated with inflammatory markers, including ESR, CRP, PCT, ferritin, and biochemical parameters such as ALT, AST, BUN, CK, and LDH. In addition, TSP-1 and TSP-2 were negatively correlated with hematological markers such as LYM, EOS, and HGB. Receiver operating characteristic analyses revealed that COVID-19 may be predicted with TSP-1 levels over 189.94 ng/mL and TSP-2 levels higher than 0.70 ng/mL.

Conclusions

Our analysis suggests that TSP-1 and TSP-2 expressions at the systemic level may have clinical importance for COVID-19.
Synthesis, characterization, luminescence, and catalytic properties of a zinc(II) complex with a N,O-donor ligand generated in situ from topiroxostat
Authors: Qin Chen-Chen , Sun Zhong-Hua , Rong Xin , Chen Sheng-Chun , He Ming-Yang , Chen Qun
Published: June 2023

By utilizing the well-known selective xanthine oxidase inhibitor topiroxostat, a new zinc(II) complex Zn(L)2(H2O)2 (1) [HL = 4-(3-(pyridine-4-yl)-1H-1,2,4-triazol-5-yl)picolinic acid] has been hydrothermally synthesized, involving in-situ ligand formation upon hydrolysis of topiroxostat. The complex has been structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. X-ray structural analysis revealed that complex 1 is a N,O-chelating mononuclear Zn(II) complex. Complex 1 shows good thermal stability and exhibits photoluminescence in the solid state at room temperature. Moreover, complex 1 has been shown to be effective in the solvent-free ring-opening polymerization of ε-caprolactone without any co-catalyst or initiator.

LABOUR MIGRATION OF THIRD-COUNTRY NATIONALS TO LITHUANIA: RECENT TRENDS AND SOCIAL POLICY RESPONSES
Authors: Brazienė Rūta , Mamaiev Dmytro , Aksu Suat
Published: June 2023

The purpose of the paper is to discuss recent immigration trends, and the policies that have been adopted by the state to facilitate the process of the integration of immigrants and their access to the labour market. The first part of the paper discusses theoretical aspects of migration, and labour migration in particular. The second part of the paper is aimed at disclosing current immigration trends among third-country nationals in Lithuania. Labour migration and the migration policy framework in Lithuania are analysed, as are integration policies. The research results reveal that Lithuania lacks an effective migrant integration policy. The evaluation of the migration policy index allows us to conclude that the policy of the integration of immigrants is the area of migration policy that needs to be improved the most in Lithuania. Lithuania’s score is lower than the average MIPEX country score, and together with Latvia it is one of the lowest in Central and East European countries. Lithuania’s approach to integration is classified by MIPEX as equality on paper. While immigrants enjoy basic rights and protection in Lithuania, they do not enjoy equal opportunities to participate in society.
The alternate pathway of androgen metabolism and window of sensitivity
Authors: Renfree Marilyn B , Shaw Geoff
Published: June 2023

Since the discovery in 1968 that dihydrotestosterone (DHT) is a major mediator of androgen action, a convincing body of evidence has accumulated to indicate that the major pathway of DHT formation is the 5α-reduction of circulating testosterone in androgen target tissues. However, we now know that DHT can also be formed in peripheral tissues by the oxidation of 5α-androstane-3α,17β-diol (adiol). This pathway is responsible for the formation of the male phenotype. We discuss the serendipitous discovery in the tammar wallaby of an alternate pathway by which adiol is formed in the testes, secreted into plasma and converted in peripheral tissues to DHT. This alternate pathway is responsible for virilisation of the urogenital system in this species and is present in the testes at the onset of male puberty of all mammals studied so far. This is the first clear-cut function for steroid 5α-reductase 1 in males. Unexpectedly, the discovery of this pathway in this Australian marsupial has had a major impact in understanding the pathophysiology of aberrant virilisation in female newborns. Overactivity of the alternate pathway appears to explain virilisation in congenital adrenal hyperplasia CAH, in X-linked 46,XY disorders of sex development. It also appears to be important in polycystic ovarian syndrome (PCOS) since PCOS ovaries have enhanced the expression of genes and proteins of the alternate pathway. It is now clear that normal male development in marsupials, rodents and humans requires the action of both the classic and the alternate (backdoor) pathways.
Neural gut-to-brain communication for postprandial control of satiation and glucose metabolism
Authors: Cabot Leonie , Erlenbeck-Dinkelmann Juliet , Fenselau Henning
Published: June 2023

The brain is tuned to integrate food-derived signals from the gut, allowing it to accurately adjust behavioral and physiological responses in accordance with nutrient availability. A key element of gut-to-brain communication is the relay of neural cues via peripheral sensory neurons (PSN) which harbor functionally specialized peripheral endings innervating the muscular and mucosal layers of gastrointestinal (GI) tract organs. In this review, we detail the properties of GI tract innervating PSN and describe their roles in regulating satiation and glucose metabolism in response to food consumption. We discuss the complex anatomical organization of vagal and spinal PSN subtypes, their peripheral and central projection patterns, and describe the limitations of unselective lesion and ablation approaches to investigate them. We then highlight the recent identification of molecular markers that allow selective targeting of PSN subtypes that innervate GI tract organs. This has facilitated accurately determining their projections, monitoring their responses to gut stimuli, and manipulating their activity. We contend that these recent developments have significantly improved our understanding of PSN-mediated gut-to-brain communication, which may open new therapeutic windows for the treatment of metabolic disorders, such as obesity and type 2 diabetes.

11β-Hydroxysteroid dehydrogenase 1 (11βHSD1) is a drug target to attenuate adverse effects of chronic glucocorticoid excess. It catalyses intracellular regeneration of active glucocorticoids in tissues including brain, liver and adipose tissue (coupled to hexose-6-phosphate dehydrogenase, H6PDH). 11βHSD1 activity in individual tissues is thought to contribute significantly to glucocorticoid levels at those sites, but its local contribution vs glucocorticoid delivery via the circulation is unknown. Here, we hypothesised that hepatic 11βHSD1 would contribute significantly to the circulating pool. This was studied in mice with Cre-mediated disruption of Hsd11b1 in liver (Alac-Cre) vs adipose tissue (aP2-Cre) or whole-body disruption of H6pdh. Regeneration of [9,12,12-2H3]-cortisol (d3F) from [9,12,12-2H3]-cortisone (d3E), measuring 11βHSD1 reductase activity was assessed at steady state following infusion of [9,11,12,12-2H4]-cortisol (d4F) in male mice. Concentrations of steroids in plasma and amounts in liver, adipose tissue and brain were measured using mass spectrometry interfaced with matrix-assisted laser desorption ionisation or liquid chromatography. Amounts of d3F were higher in liver, compared with brain and adipose tissue. Rates of appearance of d3F were ~6-fold slower in H6pdh−/−
mice, showing the importance for whole-body 11βHSD1 reductase activity. Disruption of liver 11βHSD1 reduced the amounts of d3F in liver (by ~36%), without changes elsewhere. In contrast disruption of 11βHSD1 in adipose tissue reduced rates of appearance of circulating d3F (by ~67%) and also reduced regenerated of d3F in liver and brain (both by ~30%). Thus, the contribution of hepatic 11βHSD1 to circulating glucocorticoid levels and amounts in other tissues is less than that of adipose tissue.

[Objetivo] Se buscó explicar el desempeño de hombres estudiantes de secundaria y universitarios de carreras no STEM, así como de carreras STEM en pruebas de contexto matemático utilizando un modelo SEM basado en la teoría del sexismo ambivalente hacia las mujeres. [Metodología] Se obtuvo información de hombres estudiantes de secundaria de áreas urbanas (2015), así como hombres de la UNA, UCR y TEC (2014) en las carreras antes mencionadas. Se estimó un SEM utilizando métodos de estimación por máxima verosimilitud y mínimos cuadrados generalizados. Ante el incumplimiento de los supuestos, se realizó la estimación utilizando la estadística bayesiana. Finalmente se analizaron las medidas de bondad de ajuste. [Resultados] Para los grupos estudiados, las relaciones tuvieron la dirección esperada. En hombres estudiantes de secundaria: la relación entre sexismo hostil y la equidad percibida en matemáticas carece de importancia práctica (coeficiente: -0.02). En hombres en carreras no STEM: la relación entre el sexismo benevolente y la equidad percibida en matemáticas carece de importancia práctica (coeficiente: 0.00). En los tres casos, entre mayor percepción de equidad, mayor autoeficacia y mayores habilidades de razonamiento, se genera mejor rendimiento en pruebas matemáticas. [Conclusiones] Las creencias sexistas influyen negativamente en la percepción de equidad en contextos matemáticos. A mayor percepción de equidad mejor rendimiento en las pruebas matemáticas. Existe relevancia de las habilidades de razonamiento en los contextos matemáticos, ya que en todos los casos se obtuvieron coeficientes positivos y altos en su relación con la prueba de contexto matemático.

A promise kept? The first years of experience of the Appeal Panel of the SRB
Authors: Lamandini Marco , Muñoz David Ramos
Published: June 2023

Within the institutional architecture for financial supervision within the EU, courts coexist with quasi-courts, i. e., review bodies like the ESAs Joint Board of Appeal, the SSM’s Administrative Board of Review (ABoR) and the SRB’s Appeal Panel. This has parallels e. g. US Administrative Law Judges (ALJs). Some argue that this flight away from courts is justified because administrative law and procedure are more flexible. Yet administrative mechanisms are deceptively simple. This paper offers a cautionary tale about the complexities of all quasi-judicial arrangements and their competing and complementary role with courts and presents an analysis of the European framework from both a functional and a comparative perspective.

Published: June 2023

Safe biodegradable “green” alternatives with minimal environmental and health risks have received widespread research interest. Thirty different kinds of bio-based flocculants (modified starches, modified celluloses, native chitosan, and lignin-based flocculant) were pre-tested using a simple jar test for the examination of the applicability of new organic flocculants in papermaking and in conditioning of waste activated sludge from the pulp and paper industry. Three starch-based and two cellulose-based polymers were chosen for further flocculation and filtrations tests. Key optimization parameters for the polymer were identified as the increasing of molecular weight and nitrogen content. The starch-based polymer had the best performance in both applications, but in neither of the cases did it function as well as the commercial polyacrylamide-based polymers. The importance of the molecular weight came up in the experiments. The developed starch-based polymer was cationic and had the charge density used in industry. On the other hand, although cationic flocculants are the most used in sludge conditioning, also anionic and non-ionic polymers are needed, depending on the characteristics of the sludge to be flocculated. Overall action of the tailored polymers was also studied in order to predict their potential as papermaking retention and dewatering aids.
The effect of lignin as a natural adhesive on the physico-mechanical properties of Vitis vinifera fiberboards
Authors: Mancera Camilo , El Mansouri Nour-Eddine , Vilaseca Fabiola , Ferrando Francesc , Salvado Joan
Published: June 2023

Lignin was used as a natural adhesive to manufacture Vitis vinifera fiberboards. The fiberboards were produced at laboratory scale by adding powdered lignin to material that had previously been steam-exploded under optimized pretreatment and pressing conditions. The kraft lignin used was washed several times with an acidic solution to eliminate any contaminants and low molecular weight compounds. This research studied the effects of amounts of lignin ranging from 5% to 20% on the properties of Vitis vinifera fiberboards. The fiberboard properties evaluated were density, water resistance in terms of thickness swelling, water absorption, and the mechanical properties in terms of modulus of rupture, modulus of elasticity, and internal bond. Results showed that fiberboards made from Vitis vinifera without lignin addition had weaker mechanical properties. However, the fiberboards obtained using acid-washed kraft lignin as a natural adhesive had good mechanical and water resistance properties that fully satisfied the relevant standard specifications.
Thermodynamic analysis of black liquor steam gasification
Authors: Huang Hua-Jiang , Ramaswamy Shri
Published: June 2023

Pulp and paper mills represent a major platform for the use of abundant, renewable forest-based biomass as raw material. The pulping processes produce a large amount of black liquor solids, which is currently burnt in a conventional Tomlinson recovery boiler for recovery of energy and inorganic chemicals. This combustion technology can recover chemicals with good efficiency, and steam and power can be produced for the mills. However, Black Liquor Gasification (BLG) can be used to substitute for the combustion process for potential higher energy efficiency, lower greenhouse gas emissions, and more safety. With BLG technology, current pulp and paper mills can be extended into future biorefineries. In this work, a thermodynamic equilibrium model using Gibbs free energy minimization approach and the software FactSage are utilized to analyze the thermodynamic equilibrium constraints of the complex multiple phase reactions and the effects of different operating conditions during black liquor gasification. The modeling results can help better understand the black liquor gasification process and be useful in process modeling and analysis of the future BLG-based biorefinery.

Oxygen plasma was determined to be capable of inducing hydrophobic modification of cotton fabric surface by utilizing the ageing effect. Upon ageing, the surface polarity was reversed and hydrophobic aliphatic hydrocarbons were formed, which was confirmed by Fourier Transform Infrared Spectroscopy. Surface hydrophobicity was quantified by the wetting area measurement. Wetted area of plasma-modified cotton was found to be strongly dependent on plasma-induced surface structures and the chemical composition on the fiber surface. Scanning electron microscopy revealed that physical morphological alteration was also a crucial factor that contributed to surface hydrophobicity. This work seeks to determine a controlled hydrophobic modification of textile materials through optimization of plasma process based on the Orthogonal Array Testing Strategy (OATS). Optimum process conditions were determined based on reduction of wetted area of plasma-modified cotton fabrics. Finally, hydrophobicity of plasma-modified cotton fabric was compared with conventional water repellency treatment.

Aspergillus sojae has been previously shown to produce exo-polygalacturonase (exo-PG) in synthetic media, where the potential of the organism to utilize agricultural substrates was not considered so far. In this study, the utilization of agro-based products was taken into account in the enhanced production of exo-PG using an A. sojae mutant by applying statistical design methods. Complex sources (orange peel, wheat bran, and corn meal), simple sugar sources (glucose, maltrin, and sugar beet syrup), and two phosphate salts were screened using D-optimal design method. Orange peel yielded the highest exo-PG activity with all simple sugars and phosphate sources. According to the results of response surface methodology (RSM), the optimum concentrations of orange peel, sugar beet syrup, and (NH4)2SO4 were found to be 10, 60, and 8 g L-1, respectively. The exo-PG activity under these conditions was 145.4 U m L-1 in shake flask cultures. In bioreactor studies enzyme production was induced at low pH values; thus highest production was obtained under uncontrolled pH conditions, in which the pH dropped to 2.0 in 72 h. As a result high exo-PG could be produced by an A. sojae mutant using a cost-effective medium containing agro-industrial substrates. Another important advantageous outcome was the low optimal pH, which is especially desired in industrial fermentations prone to contamination problems. In fact this highlights the easy adaptation of this fermentation to industrial scales.

A 74-year-old woman was admitted for weight loss, abdominal pain and diarrhea for a year. Blood tests showed elevated transaminases, cholestasis and hyperbilirubinemia. Capsule endoscopy revealed extensively scattered lymphangiectasias, shortened villi and erosions in the jejunum and ileum. The histological examination of the small bowel mucosa biopsies evidenced severe mucosal atrophy and crypt hyperplasia, without significant intraepithelial lymphocytosis. The clinical picture, lack of response to a gluten-free diet and endoscopic and histopathologic findings were compatible with autoimmune enteropathy. Simultaneously, autoimmune hepatitis was also diagnosed. The patient showed significant improvement after starting treatment with prednisolone and azathioprine. To our knowledge, this is the first case of autoimmune enteropathy diagnosed simultaneously with autoimmune hepatitis.
Update on the role of Chemokines and Chemokine Receptors in Liver Fibrosis
Authors: Li Hui
Published: June 2023

Chemokines play a critical role in cell migration and activation through binding to G-protein coupled cell- surface receptors with seven transmembrane domains. Chemokines are subdivided into four superfamilies including the CC, the CXC, the CX3C and the C families and the receptors of chemokines also segregate into four families including the CCR, CXCR, CX3CR and XCR families. Most chemokine receptors can bind to more than one chemokine and some chemokines also can bind to more than one receptor. There is ligand- receptor restriction during the binding of chemokines and special receptors. Interaction between chemokines and their receptors exerts a critical role in liver fibrogenesis through recruiting a variety of inflammatory cells into injured liver. The roles of chemokines including the CC, CXC and CX3C families on liver inflammation and fibrosis were described by the Wasmuth HE team ten years ago. Abundant evidence for pro-fibrotic or anti-fibrotic roles of chemokines and their receptors in liver fibrosis has been provided in the past decade. This paper is drawing on new evidence that has come up over the past 10 years, and uses that evidence to advance the understanding of chemokines‘ roles.

Background and Aims: To compare the efficacy and safety of transarterial chemoembolization (TACE) + lenvatinib (TACE+L) versus lenvatinib (L) monotherapy in the treatment of advanced hepatocellular carcinoma by a meta-analysis.

Methods: PubMed, Embase, the Cochrane Library, CNKI, VIP e-Journals Database, and Wanfang Data were systematically searched to collate literature comparing TACE+L with L alone for the treatment of advanced liver cancer. The literature search, quality assessment, and data extraction were performed independently by two reviewers. The Stata 16 software package was used to process and analyze the data. We assessed heterogeneity using both I2 and the p-value, performed a publication bias assessment, and conducted a sensitivity analysis.

Results: Five studies were finally included, including one randomized controlled study and four retrospective studies; these involved a total of 1,167 patients, including 523 patients in the TACE+L combination group and 644 patients in the L monotherapy group. In this meta-analysis, the TACE+L group showed a significantly better objective response rate (ORR) (OR=2.54, 95%CI: 1.34 - 4.80) and disease control rate (DCR) compared to the L monotherapy group (OR=2.68, 95%CI: 1.75 - 4.08). The combined group had significantly improved progression-free survival (PFS) (HR=0.47, 95%CI: 0.40 - 0.56) and overall survival (OS) (HR=0.48, 95%CI: 0.39-0.59). In addition, there was no significant difference found in the overall adverse events of any grade between the two groups (OR=1.13, 95%CI: 0.99 - 1.29).

Conclusions: Compared to L alone, TACE+L treatment resulted in better tumor response, better long-term survival, and was accompanied by controllable adverse events.

Background and Aims: Endoscopic papillary balloon dilation (EPBD), a low-risk procedure for bleeding, hasbeen suggested as an alternative to endoscopic sphincterotomy for papillary dilatation in patients undergoingendoscopic stone removal who are at a higher risk of bleeding. Several guidelines recommend that combinationof two antiplatelet agents should be reduced to single antiplatelet therapy when endoscopic sphincterotomyis performed. However, there is no evidence that EPBD affects the risk of bleeding in patients receiving acombination of two antiplatelet agents; thus, we aimed to explore this problem.

Methods: We included 31 patients who underwent EPBD for common bile duct stones at our hospital fromMay 2014 to August 2022 and received either a combination of two antiplatelet agents or single antiplatelettherapy prior to the procedure. The group receiving a combination of two antiplatelet agents included patientswho underwent EPBT without antiplatelet therapy withdrawal or with a shorter withdrawal period than thoserecommended by the guidelines.

Results: In the group that received a combination of two antiplatelet agents, one of the two antiplateletagents used was thienopyridine. No bleeding was observed after EPBD in this study. We did not findany significant between-group differences in hemoglobin levels and rate of post-endoscopic retrogradecholangiopancreatography pancreatitis.

Conclusions: In patients treated with a combination of two antiplatelet agents, EPBD could be safely performedwithout bleeding. Therefore, future prospective studies are warranted.

Published: June 2023

Background and Aims: In the presence of malignant dysphagia in non-surgical candidates, a self-expanding metal stent (SEMS) represents a safe and effective approach. Recently, a through-the-scope (TTS) SEMS was launched. The aim of our study was to assess the feasibility and safety of the TTS versus over-the-wire (OTW) SEMS in patients with malignant dysphagia.

Methods: This single-center retrospective cohort study included patients with malignant dysphagia undergoing esophageal TTS and OTW-SEMS from 2012 to May-2022. The primary outcomes were the technical and the clinical success of the SEMS placement. Secondary outcomes included adverse events, patency, and survival. Patients were prospectively followed until death or loss of follow-up.

Results: A total of 98 patients were enrolled, including 34 patients in the TTS group and 64 patients in the OTW group. TTS and OTW SEMS placement were feasible in 33 (97.1%) and 64 (100%) procedures , respectively (p=0.118). Overall, 32 patients (94.1%) in the TTS group and 62 patients (96.9%) in the OTW group showed an improvement in Ogilvie score (p=0.432). Recurrent dysphagia occurred in 30 patients, 12 in TTS group and 18 in OTW group, due to migration (4 vs. 5), stent deformation (1 vs. 1), tissue ingrowth (5 vs. 5) and overgrowth (2 vs. 7). No patient died from a stent-related cause. Median survival was 123 days (IQR: 59-209) in TTS group and 113 days (IQR: 73-271) in OTW group (p=0.349).

Conclusions: Placement of esophageal TTS and OTW stents resulted in similar technical and clinical outcomes, stent patency and survival in patients with malignant dysphagia.

Published: June 2023

Background and Aims: Primary liver cancer (PLC) ranks among of the most common cancers worldwide. Within this group, a minority of cases displays characteristics of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA), known as combined hepatocellular cholangiocarcinoma (cHCC- CCA). Currently, there is no specific standardized therapy for these mixed tumors. Therefore, the aim of our study was to analyze the clinical course, treatment and outcome of cHCC-CCA patients in a European population-based registry.

Methods: We investigated 9,144 patients with PLC (6,622 HCC, 2,356 iCCA, and 166 cHCC-CCA) diagnosed between 2009 and 2020. All data were obtained from Clinical Cancer Registry of Baden-Württemberg (BW), Germany.

Results: In all three groups patients were predominantly male (82%, 57%, and 68% for HCC, iCCA and cHCC-CCA groups, respectively). 48% of cHCC-CCA patients were diagnosed as stage IV cancers, which was more than for HCC (31%) but less compared to CCA (64%). Overall median survival of cHCC-CCA patients was worse compared to HCC (9-13 months vs. 15.5 months, p<0.001) and rather comparable to CCA (11.8 months).

Conclusions: Our data demonstrated that cHCC-CCA tumors appear to have a distinct clinical course with worse overall survival compared to HCC. Thus, identification of these cancers by histopathology is essential in order to further characterize this tumor entity and to provide accurate treatment to these patients.

Published: June 2023

This report showed the clinical manifestations of a 26-year-old patient who was admitted to our hospital with epigastric discomfort. Computed tomography (CT) showed a hyper-density linear object Esophagogastroduodenoscopy (EGD) revealed a submucosal bulge in the gastric antrum. And endoscopic ultrasonography (EUS) demonstrated a hyperechoic lesion with a posterior shadowing in the anechoic area. Based on the above results, a diagnosis of fishbone invasion into the antral submucosa was considered. Then endoscopic submucosal dissection (ESD) was performed and a 3-cm-long fishbone was extracted with the forceps. As a rare case, the imaging findings of the fishbone under the endoscopy and the computed tomography were described.
