The Year in Hungarian Cardiology 2022: Arrhythmias
Authors: Vámos Máté , Kupó Péter
Published: July 2023

The year 2022 yielded remarkable scientific papers from Hungary from the field of cardiac arrhythmias. During the search for improved efficacy of pulmonary vein isolation (PVI) interesting topics, such as first-line cryoballoon ablation, use of visualizable steerable sheaths, ablation on the intervenous carina, high-power and very high-power short-duration ablation techniques were investigated. We also learned important lessons from studies investigating the relationship between left atrial anatomy assessed by cardiac computed tomography (CT) and acute/long-term outcomes of PVI procedures. In the field of ablation of supraventricular tachycardias (SVT) researchers demonstrated better outcomes with prophylactic ablation of the peri-incisional isthmus in postoperative atrial flutters, limitations of ventricular pacing maneuvers in paroxysmal SVT diagnostics, the superiority of intracardiac echocardiography (ICE) guided slow pathway ablation, and the feasibility and safety of zero/minimal fluoroscopy approach. Detailed baseline characteristics of patients from the BUDAPEST-CRT Upgrade Trial (NCT02270840.) were reported. Regarding cardiac resynchronization therapy interesting details were also published about reverse electrical remodeling, and the impact of premature ventricular contractions on atrial remodeling. We got valuable data on the comparative efficacy and safety of laser vs. mechanical lead extraction sheaths. In the field of genetics of cardiac arrhythmias, a robust systematic review was performed and published by a Hungarian multicenter collaboration about the different phenotypic and genotypic manifestations of the CACNA1C gene mutations. Finally, a focused issue of the Cardiologia Hungarica on cardiac arrhythmias should be highlighted.
Development of a Fluctuating Charge Model for Zinc Containing Metalloproteins
Authors: Landry Luke , Li Pengfei
Published: July 2023

The fluctuating charge (FQ) model can generate atomic charges much more efficiently than quantum mechanical methods. The FQ model has been developed for a wide range of applications, but few models were specifically tailored for calculating atomic charges of metalloproteins. Zinc-containing proteins widely exist in biology and play important roles in various processes. In this study, we present a fluctuating charge model for zinc-containing metalloproteins based on the charge equilibration (Qeq) scheme. Our model was parameterized to reproduce CM5 charges, which demonstrated excellent performance in reproducing molecular dipole moments. During our study, we found that adding the Pauling-bond-order-like term (referred to as the "+C term" in a previous study) between the zinc ion and ligating atoms significantly improves the model's performance. Although our model was trained for four-coordinated zinc sites only, our tests indicated it can well describe the atomic charges in five- and six-coordinated zinc sites as well. Finally, we adapted our model to generate partial charges for the metal site in a zinc finger domain. These charges exhibited comparable performance to the widely used restrained electrostatic potential (RESP) charges in molecular dynamics (MD) simulations. The current model can be extended to other metal-containing systems and serve the molecular modeling community.

Published: July 2023

The dehydrogenation chemistry has long prevailed in the paradigm of organic synthesis. More common with carbonyl compounds, many classical reactions evolved around it. The emergence of the transition metal catalysis redefined the dehydrogenation chemistry with strategies such as transfer dehydrogenation, C-H activation and single electron transfer processes. These strategies have been extended to enable multiple dehydrogenations that had led to aromatization depending on the substrate class. On a contrary, dehydrogenative transformations of aliphatic carboxylic acids offers substantial challenges. Engineered ligands in conjunction with metal catalysis can effectuate the dehydrogenation in carboxylic acids initiated by C-H activation with subsequent functionalization or vice versa; however, the reactivity and product formation vary with the substrate structure. Herein, we have developed a catalytic system that enables cyclohexane carboxylic acid to undergo multifold C-H activation to furnish olefinated arenes implying 3D to 2D conversion and thus, completely bypassing the lactone formation, showcasing a display of the change in reactivity of aliphatic carboxylic acids. The reaction occurs via a tandem dehydrogenation-olefination-decarboxylation-aromatization sequence which has been proved by various control experiments and isolation of key intermediates. For cyclopentane carboxylic acid which are reluctant to aromatization, the same catalytic system allows controlled dehydrogenation to provide difunctionalized cyclopentene derivatives via a tandem dehydrogenation-olefination-decarboxylation-allylic acyloxylation reaction sequence. The transformation is amenable to diversify carboxylic acids to be transformed to molecules of new identity having applications in different fields thus underscoring the im-portance.
Thermal-annealing Enhanced Room-temperature Phosphorescence of Polymer-based Organic Materials
Authors: Wang Peng , Qiu Lu , Wu Jintong , Wen Tao
Published: July 2023

Polymer-based organic room-temperature phosphorescent (RTP) materials have recently attracted significant attention. In most of the previous works, ‘chemical approaches’ have been applied to improve the performance of RTP materials, such as designing certain phosphors or selecting specific polymeric matrixes. However, enhancing triplet emission through facile ‘physical approaches’ is rarely reported. In this study, we report enhanced RTP emissions of phosphor-doped polymers by thermal annealing. By doping a difluoroboron β-diketonate derivative into poly(diacetone acrylamide) (PDAAM), green RTP emissions can be obtained. After thermal annealing at 125 °C for 5 min, the afterglow duration of RTP increased from 2.6 s to 5.3 s, and also the brightness of RTP emission exhibited a 3-fold increase. Such post-treatment is applicable for various polymeric matrixes. The mechanism underlying thermal-annealing enhanced RTP was investigated. Moreover, it demonstrated that controlled RTP by thermal annealing can be used in information encryption and anti-counterfeiting. This work provides new insight into the development of organic RTP materials with tunable emissions.
Modification of kitchen blenders into controllable laboratory mixers for mechanochemical synthesis of atomically thin materials
Authors: Perez-Alvarez Diego , Brown Jacob , Stafford Jason
Published: July 2023

Graphene and related two-dimensional materials (2DMs) have shown promise across numerous technology areas including flexible electronics, energy storage and pollution remediation. Research into novel applications of these atomically thin materials relies on access to synthesis techniques for producing 2DMs with suitable quality and quantity. Liquid-phase exfoliation is a mechanochemical approach that can achieve this and produce defect-free nanomaterial dispersions which are compatible for downstream use (e.g. inkjet printing, coatings). Here, using kitchen blenders to deliver shear-driven exfoliation, we develop a range of inexpensive hardware solutions that can allow researchers to synthesise 2DMs using a controllable, sustainable and scalable process. Extensive modifications were necessary as the onboard electronics lack the experimental controls (temperature, speed, characterisation) for scientific research and precision synthesis. The technical aspects (including the many lessons learned) of the modifications are discussed and a simple selection process is proposed for creating bespoke mechanochemical processors for any application in the hope that this encourages experimentation. Specific builds with detailed notes, cost breakdown and associated files are provided in the Open Science Framework (OSF) repository, OpenLPE associated with this article.

Published: July 2023

The increasing global population is putting huge pressure on food production system. The improper use of fertilizers, in particular, is contributing to climate change and biodiversity loss. Existing soil monitoring techniques have serious shortcomings as they are lab based and have slow turnaround times. New digital approaches are therefore urgently required to provide timely, actionable, local data on soil and water quality across each field on a farm to maximize crop yield, eliminate waste and minimize environmental pollution. To this end, we present a reagent-free, easy-use, cost-effective, accurate electrochemical phosphate sensor with a limit of detection of 10.4 nM and sensitivity of 1.18 A/nM to allow continuously, in-field soil phosphate monitoring.
Spectrophotometric Change of Butterfly Pea (Clitoria ternatea L.) Flower Extract in Various Metal Ion Solutions During Storage
Authors: Marpaung Abdullah Muzi , Pustikarini Dania
Published: July 2023

This study aimed to investigate the effect of six chloride salts on butterfly pea flower extract’s anthocyanins stability. The salts were NaCl, KCl, CaCl2, MgCl2, FeCl3, and AlCl3. The samples were analyzed using a UV-Vis spectrophotometer to observe color degradation and change in hue during storage. The extraction of anthocyanins was done using a modified method, and the solutions were stored in dark vials at room temperature. The degradation kinetics of benzene derivatives, acyl groups, non-anthocyanin flavonoid, flavylium cation, quinonoidal base and anionic quinonoidal base were evaluated using the first-order reaction, and the half-life was calculated. The effect of metal ions was studied by analyzing the change in absorbance of each band using regression analysis and a slope test. The results showed that monovalent (Na+ and K+) and divalent (Ca2+ and Mg2+) ions did not result in a significant shift in the spectrogram. Trivalent metal ions (Al3+ and Fe3+) had limited interaction with the anthocyanins, heightened the brown color, and decreased the overall color quality. K+, Ca2+, Mg2+, Al3+, and Fe3+ ions showed the ability to improve the stability of the extract’s color, while Na+ tended to accelerate color degradation. The pattern of changes in the spectrogram during storage suggests that color degradation occurs in two ways: the unfolding of hydrophobic interactions and the deacylation of anthocyanin. Trivalent metal ions showed the best stability performance, with Fe3+ preventing the unfolding of hydrophobic interactions and Al3+ hindering the deacylation. The combination of the two is highly likely to improve the color stability of the butterfly pea flower extract. However, both increase the browning index, thus decreasing color quality. This research highlights the potential of adding cations to improve the color stability of the butterfly pea flower extract, making it a more attractive food coloring agent.
Analysis of Extreme Heat Land Surface Temperature at a Tropical City (1988-2022): A Study on the Variability of Hot Spot during El Niño Southern Oscillation (ENSO)
Authors: Eboy Oliver Valentine , Kemarau Ricky Anak
Published: July 2023

Weather and climate in Malaysia, situated in Southeast Asia, are influenced by El Niño Southern Oscillation (ENSO), monsoons, Madden Julian Oscillation (MJO), and Indian Ocean Dipole (IOD). Previous studies on ENSO’s impact on temperature lacked detailed spatial information due to limited meteorological stations and cost constraints. This study utilizes remote sensing techniques, employing Landsat satellite data and Oceanic Niño Index (ONI) data, to analyze the spatial pattern of extreme land surface temperature distribution during ENSO events. Preprocessing includes radiometric and atmospheric corrections before converting digital numbers to land surface temperature values. Results indicate increased hotspot areas (>30°C) during El Niño events, with respective hotspot areas of 89.32 km² and 97.8 km² in 2015 and 2016, and 61.23 km² and 59.73 km² during La Niña in August and October 2018. Heat concentration areas remained consistent during the 1998 El Niño (89.32 km²) and the 2011 La Niña (55.82 km²). These findings highlight ENSO’s influence on altering hotspot distribution patterns. The increased hotspot area during El Niño events (34-36 km²) led to a 20-30% surge in electricity consumption as residents and offices in Kuching City, Sarawak, sought temperature regulation. This spatial information aids the government in identifying affected areas and implementing suitable measures to mitigate the impact of El Niño events.
Bismuth Silicate/Silica-Titania Synthesis from In Situ Decomposition of Oil Palm Leaves as Silica Source
Authors: S Salprima Yudha , Adfa Morina , Istiqphara Swadexi , Reagen Muhamad Alvin
Published: July 2023

In this work, bismuth silicate-titania has been synthesized in two stages by utilizing bismuth oxynitrate as an elemental source of bismuth, oil palm leaves (OPL) as a source of silica and titanium tetraisopropoxide (TTIP) as source of titania (TiO2). In the first stage, bismuth silicate/silica (Bi4Si3O12/SiO2) was formed, which occurs due to the in-situ decomposition of palm leaves and reacts directly with the bismuth precursor at high temperatures (900oC). The reaction could possibly occur through a solid-state reaction mechanism between bismuth oxide and silica or through a more complex mechanism within the reaction mixture. The resulting product then reacts with TTIP, which is added and heated at the same temperature to form Bi4Si3O12/SiO2-TiO2 (bismuth silicate/silica-titania). Characterization of the as-prepared product using X-ray diffraction showed the dominance of bismuth silicate and small amount of titania (TiO2). As a result, TiO2 could not be detected in the diffractogram. Nevertheless, an analysis using energy-dispersive X-rays showed the presence of titanium elements in the resulting composite. The results of this study can be used to develop ternary metal oxides based on natural resources and agricultural wastes, such as oil palm leaves.

Published: July 2023

Curcumin has various bio-functional properties; however, curcumin poor bioavailability reduces its efficacy. Nanoemulsion delivery system is an alternative method improving curcumin bioavailability in which surfactant and oil used, play an important role in determining nanoemulsion properties. Several studies on curcumin nanoemulsions apply synthetic surfactants which can be harmful if they are added excessively. This study aims to use a natural emulsifying agent, namely okra mucilage extract (OME), and determine its effectiveness as co surfactant. OME is safe to use as an emulsifying agent because it is natural, harmless, safe, biodegradable and eco-friendly. Liquid-liquid and microwave extraction methods were used to obtain OME which was further identified using Fourier Transfer Infrared Spectroscopy (FTIR). Meanwhile, sonication method was used to produce curcumin nano-emulsion (CurN). The particle size and polydispersity index of curcumin nano-emulsion were measured using Particle Size Analyzer (PSA) with Dynamic Light Scattering (DLS) technique, while the morphology of the nanoemulsion was observed using a Digital Imaging Microscope and Confocal Laser Scanning Microscope (CLSM). The results showed that the addition of 0.0160 g OME at a ratio of 1:5 (OME: Tween 80) in the preparation of 5 mL of CurN was able to reduce the particle size and polydispersity index from 740.80 ± 9.70 nm to 289.20 ± 2.23 and 0.340 ± 0.005 to 0.165 ± 0.008 respectively. OME increased the encapsulation efficiency from 77.93 ± 6.59% to 87.17 ± 1.12% which was confirmed by the augmentation of the fluorescence intensity of curcumin from 192.82 to 388.55. The addition of OME also maintained the stability of the CurN up to 14 days of storage at 4°C.

Usos de narrativas constructivas sobre los problemas públicos de los cibermedios iberoamericanos
Authors: Rojas-Calderón Alfredo
Published: July 2023

El tratamiento de las preocupaciones generalizadas puede seguir la tradicional negatividad del periodismo o, contrariamente, presentar un enfoque de la psicología positiva. Esta comunicación tiene como objetivo identificar y caracterizar los usos de narrativas constructivas aplicados por los medios nativos digitales del área iberoamericana en la producción de informaciones sobre los problemas públicos. La metodología de este trabajo contempla el análisis de contenido de 587 medios nativos digitales registrados en el directorio público de la organización SembraMedia. Siguiendo una lógica deductiva para revelar la situación concreta, se encontró que sólo dos, Base Pública en Chile y RED/ACCIÓN en Argentina, adoptan y desarrollan plenamente el modelo periodístico constructivo y de soluciones. La tendencia en la producción informativa de casi todos sigue los patrones tradicionales de posicionar el drama sobre las soluciones, la denuncia por encima de las propuestas y los culpables en lugar de los promotores.

Published: July 2023

El objetivo de este trabajo es identificar las estrategias metodológicas desarrolladas desde la comunicación para abordar los movimientos sociales e Internet. Se ha construido un estado del arte sobre las temáticas y los diseños metodológicos empleados para abordar las relaciones entre Internet y los movimientos juvenil, feminista y LGBT+ en México entre 2017-2022. Los resultados muestran dos campos metodológicos para abordar la relación movimientos sociales e Internet: mientras que con los métodos digitales se indaga sobre los productos generados por los usuarios de un movimiento social y la interactividad, los métodos convergentes se enfocan en los usos que activistas le dan a Internet y la experiencia obtenida a través de la interacción. Estos hallazgos permiten observar las nociones conceptuales sobre Internet como objeto de estudio y fuente de información. Ya sean digitales o convergentes, las estrategias metodológicas articuladas desde la comunicación son transversales al ámbito social y digital.

Tilapia cultivation in Nagrak Village has been practiced for a long time as one of the community's sources of income. The aquaculture business is still carried out traditionally such as the use of ground ponds, feeding management that relies on natural feed, packaging that is not in accordance with standards, and fish marketing that only uses the direct selling technique (word of mouth). The obstacles faced by partners are limited knowledge on utilizing the potential of tilapia cultivation and processing, as well as the lack of planning and strategies of product marketing. This community service activity aims to provide insight into the potential for tilapia business development, introduce processed small tilapia fish called crispy baby fish as a healthy snack with economic value, and explain the description of business analysis, good packaging techniques, and online marketing. This activity was carried out with a socialization method or presentation of material to the Family Welfare Empowerment (PKK) group of 35 people. The material presented were introduction to tilapia farming, the business potential of crispy tilapia snacks, an overview of business analysis, and online marketing strategies. The conclusion obtained from community service activities in Nagrak Village is needed for training activities to increase community knowledge and skills on developing the potential of the tilapia business.

Mondd, hogy vagy így? (Like a Rolling Stone)
Authors: Győri Péter
Published: July 2023

A tanulmány arra keresi a választ, hogy az aktuálisan hajléktalan élethelyzetben lévő emberek számára – hangsúlyozottan a saját, egyéni szempontjaik, megfogalmazásuk szerint – milyen előnyei vannak annak a helynek, ahol éjjeleiket, és sokszor nappalaikat is töltik. Mi vezérli döntéseiket, amikor arról van szó, hogy aznap hol fogják éjszakájukat tölteni, hol fognak aludni. E kérdés megválaszolásához a tanulmány a 2022. évi országos hajléktalanügyi adatfelvétel mintegy 6200 szabadszavas válaszainak a tartalomelemzését alkalmazza.

Az elemzés rávilágít arra, hogy a hajléktalan emberek számára – másokhoz hasonlóan – nem csupán a lakhatás olyan primer, fizikai jellemzői a meghatározóak, mint a fedél, a fűtés, az alvási és tisztálkodási lehetőség, illetve a létfenntartás legelemibb feltételeinek, mint amilyen például az élelmiszerhez jutás. Legalább ilyen fontos számukra, hogy az általuk elérhető lakhatási lehetőség egyben rendelkezzen az otthon legfontosabb jellemzőivel is, mint a biztonság és a privát szféra adta önállóság és szabadság.

A hajléktalan embereket segítő szakemberek számára is tanulságul szolgálhat, hogy mennyiben térnek el egymástól a különböző szállásokon élők és a fedél nélkül élők motivációi, értékpreferenciái, amikor arról van szó, hogy melyek is az egyes alvóhelyek előnyei számukra, mi alapján dőlhet el, hogy valaki „bemegy-e szállóra”, vagy éppen huzamosabb ideig inkább „kint marad”.

Authors: Padida Sathwika , K Srinivas
Published: July 2023

Technology is being adopted in various sectors worldwide at a significantly faster pace, especially since the COVID-19 pandemic breakdown as well as the subsequent lockdown, which has proved very beneficial in a lot of aspects. The ACE industry (architecture, construction and engineering) is a very labor-intensive industry by its nature and the adoption of technology has been at a slower pace than the other sectors. However, the intervention of technology in the industry is comparatively more unrushed. Construction is one of the longest-standing industries in India. Technology adoption in the construction industry in India has not been to the desired extent. A wider use of the Metaverse technology can be expected in the Indian construction industry if the companies appreciate its benefits. This paper aims to give an overview of the state of adoption of the Metaverse technology in the Indian construction industry. An analysis of the benefits that could be derived from technology adoption and the hindrances that are posing a setback for the adoption were achieved in this study. The benefits of Metaverse adoption are multi-fold with a wide range of activities beginning from design conceptualization, proposals, project planning, coordination, tracking work progress, training and many more.

This paper analyzed the place of interpersonal communication as a means of tackling voter apathy among Nigerian youths. The study is a survey. Survey was used to analyze how interpersonal communication can be used as a means to tackle voter apathy among residents of Akwa Ibom state. The population of this study was 384 residents in Uyo Urban. The study investigated the causes of voter apathy among youths in Uyo, the extent interpersonal communication influences voter turnout and political behavior among youths in Uyo and the sources of interpersonal communication that are most effective in influencing youths’ behavior and decision. The results from this study not only revealed that interpersonal communication influenced the electorate voting behavior during the 2023 general elections, it was also the greatest influence on the political behavior of the electorates. Also, the results showed that individuals who discussed voting more often had more positive attitude towards voting and were more likely to vote in an election. The study, among others, recommends that politicians and political parties should strive to inculcate interpersonal communication as a key component in political campaigns because it not only helps to eliminate voter apathy, it also creates an opportunity for the electorates and the politicians, to have a face-to-face interaction, which would otherwise, be impossible with mass media.

The study determined the electrical performance of dye sensitized solar cell by using electrolyte hydrogels of Polyethylene Glycol 4000 and Polyethylene Glycol 6000. The experimental work consisted of Dye Sensitized Solar Cell (DSSC) structure arrangement, assembly of DSSC layers, and measurement of DSSC. The resistances of TCO glass were 1.1 kΩ and 14.9 kΩ. The concentration of the thickening agents in the electrolyte solution were 5%, 10%, and 15%, and a control sample without the addition of hydrogel. The parameters included total anthocyanin content of senduduk fruit, voltage and current values, output and input power values, fill factor, and DSSC efficiency. The best DSSC performance was DSSC with the addition of PEG 6000 at a concentration of 15%, and its electrical characteristics were Isc: 0.0127 mA, Voc: 0.721 mV, Imax: 0.0102 mA, Vmax: 0.508 mV, Pmax: 0.00518 mW, FF: 0.5659, and an efficiency of 0.018%.
Review on brain-targeted drug delivery

Published: July 2023

Brain-targeted drug delivery is a field of research that seeks to develop new methods for delivering drugs to the brain. This is done by overcoming the blood-brain barrier (BBB), a network of cells that tightly regulate the flow of substances between the blood and the brain. Most of the time lipophilic drugs are easily cross blood brain barrier but few of them less soluble in lipid therefore they don’t cross the blood brain barrier. After review we concluded that we can easily improve the solubility of drug using various techniques and Brain-targeted drug delivery is a promising field of research that has the potential to revolutionize the treatment of brain diseases. With further advances, it is possible that brain-targeted drug delivery will become a standard treatment for a variety of brain diseases and disorders.

Published: July 2023

Objectives : This review aimed to evaluate the effect and clinical utilization of chuna manual therapy (CMT) for constipation predominant irritable bowel syndrome.
Methods : Literature search was conducted using 12 electronic databases: PubMed, EMBASE, The Cochrane Library, Ovid, Web of Science, Chinese Academic Journals, KMBASE, ScienceOn, Korea Med, OASIS, KISS, and RISS. Only randomized controlled trials (RCTs) using CMT for constipation predominant irritable bowel syndrome treatment were included. The risk of bias of each RCT was evaluated using the Cochrane risk of bias tool.
Results : Seven RCTs met the inclusion criteria. CMT alone and CMT combined with Western medication showed positive result on constipation predominant irritable bowel syndrome treatment. Two RCTs that compared CMT alone with placebo medicine showed partially positive results in meta-analysis. However, vasoactive intestinal peptide and cholecystokinin values of these studies were evaluated in an opposite way; thus, meta-analysis of these values were not conducted.
Conclusions : CMT may be effective and clinically utilizable for constipation predominant irritable bowel syndrome treatment. However, there is limited evidence due to lack of well-designed RCTs. Further well-designed RCTs are needed for stronger evidence.

Objective This study aimed to investigate the prevalence, clinical characteristics, and the correlates of nonsuicidal self-injury (NSSI) in firefighters. We also investigated the mediating role of NSSI frequency in the association between posttraumatic stress disorder (PTSD), depression, and suicidal behavior.Methods A total of 51,505 Korean firefighters completed a web-based self-reported survey, including demographic and occupational characteristics, NSSI, PTSD, depression, and suicidal behavior. Multivariable logistic regression analyses and serial mediation analyses were performed.Results The 1-year prevalence of NSSI was 4.67% in Korean firefighters. Female gender, the presence of recent traumatic experience, and PTSD and depression symptoms were correlated with NSSI. Serial mediation analyses revealed that NSSI frequency mediated the association between PTSD, depression, and suicidal behavior; it indicates more severe PTSD was sequentially associated with more severe depression symptoms and more frequent NSSI, leading to higher risk of suicidal behavior.Conclusion NSSI is prevalent and may play a significant mediating role when PTSD is associated with suicidal behavior in firefighters. Our results imply the need for screening and early intervention of NSSI in firefighters.

Objective Specific learning disorder (SLD) is a neurodevelopmental disorder in which underlying pathogenesis and etiological factors are not fully understood. Neuroinflammatory response (measured with serum levels of galectin-1 and galectin-3), which is associated with learning and memory, may play an important role in the etiopathogenesis of SLD. Aim of the present study is to examine whether serum galectin-1 and galectin-3 levels are related to SLD.Methods The current study consisted of 42 treatment-naive children with SLD and 42 control subjects. All of the subjects were assessed using semi-structured psychiatric examination to diagnose SLD and exclude attention-deficit hyperactivity disorder. Serum galectin-1 and galectin-3 levels were measured via venous blood samples.Results The SLD and control group did not differ significantly in terms of age, sex, and body mass index (BMI). The SLD group had significantly higher serum levels of galectin-1 (8.78±2.97 vs. 7.40±2.03, p=0.019) and galectin-3 (1.86±0.93 vs. 1.32±0.69, p=0.003) than the control group when controlled for age, sex, and BMI.Conclusion Higher serum levels of galectin-1 and galectin-3 in children with SLD may indicate the role of neuroinflammatory response in the pathogenesis of SLD. Other mechanisms involving galectin-1 and galectin-3 related to learning may play a part in the etiology of SLD.
