RESUMO
The field of bone tissue engineering aims to develop an effective and aesthetical bone graft substitute capable of repairing large mandibular defects. However, graft failure resulting from necrosis and insufficient integration with native tissue due to lack of oxygen and nutrient transportation remains a concern. To overcome these drawbacks, this study aims to develop a 3D printed polycaprolactone layered construct with a LEGO®-inspired interlocking mechanism enabling spatial distribution of biological components. To highlight itsin vitroosteogenic potential, human mesenchymal stromal cells are cultured onto Bio-Gide®Compressed collagen (Col) membranes, which are embedded within the layered construct for 28 d. The osteogenic response is assessed through the measurement of proliferation, relevant markers for osteogenesis including alkaline phosphatase (ALP) activity, expression of transcriptional genes (SP7, RUNX2/SOX9) as well matrix-related genes (COL1A1, ALPL IBSP, SPP1), osteoprotegerin secretion.In vitroosteogenic differentiation results showed increased levels of these osteogenic markers, indicating the layered construct's potential to support osteogenesis. In this study, a novel workflow of 3D printing a patient-specific LEGO®-inspired layered construct that can spatially deliver biological elements was successfully demonstrated. These layered constructs have the potential to be employed as a bone tissue engineering strategy, with particular focus on the repair of large mandibular defects.

In the pediatric population, epilepsy is one of the most common neurological disorders that often results in cognitive dysfunction. It affects patients' life quality by limiting academic performance and self-esteem and increasing social rejection. There are several interventions for the neurohabilitation of cognitive impairment, including LEGO®-based therapy (LEGO® B-T), which promotes neuronal connectivity and cortical plasticity through the use of assembly sets and robotic programming. Therefore, the aim of this study was to analyze the effect of LEGO® B-T on cognitive processes in pediatric patients with epilepsy. Eligible patients were identified; in the treatment group, an initial evaluation was performed with the NEUROPSI and BANFE-2 neuropsychological tests. Then, the interventions were performed once a week, and a final test was performed. In the control group, after the initial evaluation, the final evaluation was performed. An overall improvement was observed in the LEGO® B-T patients, with a significant increase in BANFE-2 scores in the orbitomedial, anterior prefrontal, and dorsolateral areas. In addition, in the gain score analysis, the orbitomedial and memory scores were significantly different from the control group. LEGO® B-T neurohabilitation is a remarkable option for epilepsy patients, who are motivated when they observe improvements.
RESUMO
One of the major functions of the semaphorin signaling system is the regulation of cell shape. In the nematode Caenorhabditis elegans, membrane-bound semaphorins SMP-1/2 (SMPs) regulate the morphology of epidermal cells via their receptor plexin, PLX-1. In the larval male tail of the SMP-PLX-1 signaling mutants, the border between two epidermal cells, R1.p and R2.p, is displaced anteriorly, resulting in the anterior displacement of the anterior-most ray, ray 1, in the adult male. To elucidate how the intercellular signaling mediated by SMPs regulates the position of the intercellular border, we performed mosaic gene expression analyses by using infrared laser-evoked gene operator (IR-LEGO). We show that PLX-1 expressed in R1.p and SMP-1 expressed in R2.p are required for the proper positioning of ray 1. The result suggests that SMP signaling promotes extension, rather than retraction, of R1.p. This is in contrast to a previous finding that SMPs mediate inhibition of cell extension of vulval precursor cells, another group of epidermal cells of C. elegans, indicating the context dependence of cell shape control via the semaphorin signaling system.

CYP116B5 is a class VII P450 in which the heme domain is linked to a FMN and 2Fe2S-binding reductase. Our laboratory has proved that the CYP116B5 heme domain (CYP116B5-hd) is capable of catalyzing the oxidation of substrates using H2O2. Recently, the Molecular Lego approach was applied to join the heme domain of CYP116B5 to sarcosine oxidase (SOX), which provides H2O2 in-situ by the sarcosine oxidation. In this work, the chimeric self-sufficient fusion enzyme CYP116B5-SOX was heterologously expressed, purified, and characterized for its functionality by absorbance and fluorescence spectroscopy. Differential scanning calorimetry (DSC) experiments revealed a TM of 48.4 ± 0.04 and 58.3 ± 0.02°C and a enthalpy value of 175,500 ± 1850 and 120,500 ± 1350 cal mol-1 for the CYP116B5 and SOX domains respectively. The fusion enzyme showed an outstanding chemical stability in presence of up to 200 mM sarcosine or 5 mM H2O2 (4.4 ± 0.8 and 11.0 ± 2.6% heme leakage respectively). Thanks to the in-situ H2O2 generation, an improved kcat/KM for the p-nitrophenol conversion was observed (kcat of 20.1 ± 0.6 min-1 and KM of 0.23 ± 0.03 mM), corresponding to 4 times the kcat/KM of the CYP116B5-hd. The aim of this work is the development of an engineered biocatalyst to be exploited in bioremediation. In order to tackle this challenge, an E. coli strain expressing CYP116B5-SOX was employed to exploit this biocatalyst for the oxidation of the wastewater contaminating-drug tamoxifen. Data show a 12-fold increase in tamoxifen N-oxide production-herein detected for the first time as CYP116B5 metabolite-compared to the direct H2O2 supply, equal to the 25% of the total drug conversion.

Many undergraduates struggle to interpret abstract concepts in molecular biology. Modeling can facilitate learning by making these abstract concepts tangible. Here, we present an exercise based on the lac operon designed for undergraduate students using LEGO bricks. The lac operon is a classic example of transcriptional regulation taught in a variety of undergraduate biology courses and is fundamental to understanding the regulation of gene expression. This easy-to-implement active learning exercise demonstrates how the various components of the lac operon are oriented under a variety of nutritional conditions to control gene expression. In addition, higher-order concepts, such as the effect of mutation on lac operon expression, can be readily modeled. Overall, students not only found this exercise to be enjoyable but also helpful as a tool to engage with this course material.
RESUMO
Fluorescence interference in Raman spectroscopy is a well-known problem and is especially significant in portable instruments where the availability of a variety of exciting wavelengths is unlikely. Several fluorescence avoidance and mitigation schemes are described in the literature, and implemented by Raman spectrometer manufacturers, but there is no standard method for evaluating the accuracy and repeatability of these schemes. Some test samples shown in instrument descriptions, such as "dark rum" and "sesame seed oil" are not reproducible. Therefore, we propose a set of colored LEGO blocks as "standard" samples for this purpose; they have the attractive properties of being very low cost, rugged, non-toxic, easy to transport and store, and appear to be manufactured using a standard process. This paper shows the Raman spectra of a set of these blocks at different excitation wavelengths, acquired on laboratory instruments, along with their visible-near-infrared spectra. The goal is to qualitatively understand the origins of the observed fluorescence and lay the groundwork for exploring the effectiveness of methods currently implemented on handheld Raman instruments.

The convergence of organoid and organ-on-a-chip (OoC) technologies is urgently needed to overcome limitations of current 3D in vitro models. However, integrating organoids in standard OoCs faces several technical challenges, as it is typically laborious, lacks flexibility, and often results in even more complex and less-efficient cell culture protocols. Therefore, specifically adapted and more flexible microfluidic platforms need to be developed to facilitate the incorporation of complex 3D in vitro models. Here, a modular, tubeless fluidic circuit board (FCB) coupled with reversibly sealed cell culture bricks for dynamic culture of embryonic stem cell-derived thyroid follicles is developed. The FCB is fabricated by milling channels in a polycarbonate (PC) plate followed by thermal bonding against another PC plate. LEGO-like fluidic interconnectors allow plug-and-play connection between a variety of cell culture bricks and the FCB. Lock-and-play clamps are integrated in the organoid brick to enable easy (un)loading of organoids. A multiplexed perfusion experiment is conducted with six FCBs, where thyroid organoids are transferred on-chip within minutes and cultured up to 10 d without losing their structure and functionality, thus validating this system as a flexible, easy-to-use platform, capable of synergistically combining organoids with advanced microfluidic platforms.

The nature of the home mathematics environment (which includes numerical and spatial activities at home) is related to children's spatial and mathematics performance. The current study investigated concrete and digital construction play frequency and relations with spatial and mathematical skills. Participants aged 7-9 years (N = 634) reported their frequency of construction play (concrete and digital) and completed direct measures of spatial ability and mathematics performance. Correlations between measures revealed no association between construction play frequency and outcome measures. This suggests that quantity of construction play is not pertinent for spatial and mathematics skills, however future research should explore whether quality of play is an important factor.

Resumo A psicologia do ego é reconhecida como uma releitura norte-americana da psicanálise, e teve Ernst Kris - que foi próximo de Freud - como um de seus fundadores. Apesar deste autor utilizar-se de textos freudianos para firmar os fundamentos de sua teoria, sustenta-se que a psicologia do ego mais se distancia do que se aproxima da obra de Freud. Este estudo visa demonstrar de que forma isso ocorre. Para isso, situa-se brevemente quem foi Ernst Kris e quais são as críticas já existentes à psicologia do ego. Num segundo momento, analisa-se o artigo "Ego Psychology and Interpretation in Psychoanalytic Therapy", de Kris, em confronto com a teoria de Freud. Por último, expõe-se a crítica de Lacan. Destaca-se que a crítica lacaniana remete a questões referentes à ética da psicanálise e ao lugar do analista na direção do tratamento.
Abstract Ego Psychology is a North-American re-reading of psychoanalysis and had Ernst Kris - a man who was close to Freud - as one of its founders. Despite using Freudian texts to establish its foundations, Ego Psychology distances itself from Freud's psychoanalysis. This study demonstrates how this occurs by briefly discussing who Ernst Kris was and the existing criticisms of Ego Psychology. Secondly, it analyzes Ernst Kris's article "Ego Psychology and Interpretation in Psychoanalytic Therapy" against Freud's theory, to finally present Lacan's critique, which refers to issues related to the ethics of psychoanalysis and the analyst's role in directing treatment.
Resumen La Psicología del Yo se considera como una relectura estadounidense del psicoanálisis y tuvo a Ernst Kris -quien era cercano a Freud- como uno de sus fundadores. A pesar de que Ernst Kris utiliza textos freudianos para establecer los fundamentos de su teoría, se sostiene que la Psicología del Yo se aleja más de la obra de Freud que se acerca a ella. Este estudio tiene como objetivo demostrar cómo ocurre esto. Para ello, se sitúa brevemente quién es Ernst Kris y cuáles son las críticas ya existentes a la Psicología del Yo. En segundo lugar, se analiza el artículo "Ego Psychology and interpretation in psychoanalytic therapy", de Ernst Kris, en confrontación con la teoría de Freud. Y, por último, se expone la crítica de Lacan. Se destaca que la crítica lacaniana remite a cuestiones relacionadas con la ética del psicoanálisis y el lugar del analista en la dirección del tratamiento.
Résumé La psychologie de l'égo est une relecture nord-américaine de la psychanalyse dont Ernst Kris, un homme proche de Freud, est l'un des fondateurs. Bien qu'elle utilise des textes freudiens pour établir ses fondements, la psychologie de l'égo s'éloigne de la pensée freudienne. Pour démontrer cet écart, cette étude aborde la figure de Ernst Kris et des critiques existantes à l'égard de la psychologie de l'égo. Ensuite, elle analyse l'article « Ego Psychology and interpretation in psychoanalytic therapy ¼ par rapport à la théorie de Freud, pour enfin présenter la critique de Lacan, qui se réfère à des questions liées à l'éthique de la psychanalyse et au rôle de l'analyste dans la direction du traitement.

Background: Social skills interventions are commonly recommended to help children and young people with autism spectrum disorder develop social skills, but some struggle to engage in these interventions. LEGO® (LEGO System A/S, Billund, Denmark) based therapy, a group social skills intervention, aims to be more interesting and engaging. Objective: To evaluate the clinical effectiveness of LEGO® based therapy on the social and emotional skills of children and young people with autism spectrum disorder in school settings compared with usual support. Secondary objectives included evaluations of cost-effectiveness, acceptability and treatment fidelity. Design: A cluster randomised controlled trial randomly allocating participating schools to either LEGO® based therapy and usual support or usual support only. Setting: Mainstream schools in the north of England. Participants: Children and young people (aged 7-15 years) with autism spectrum disorder, their parent/guardian, an associated teacher/teaching assistant and a facilitator teacher/teaching assistant (intervention schools only). Intervention: Schools randomised to the intervention arm delivered 12 weekly sessions of LEGO® based therapy, which promotes collaborative play and encourages social problem-solving in groups of three children and young people with a facilitator (trained teacher or teaching assistant). Participants received usual support from school and community services. Participants in the control arm received usual support only. Research assistants and statisticians were blind to treatment allocation. Main outcome measure: The social skills subscale of the Social Skills Improvement System (SSIS), completed by the children and young people's unblinded teacher pre randomisation and 20 weeks post randomisation. The SSIS social skills subscale measures social skills including social communication, co-operation, empathy, assertion, responsibility and self-control. Participants completed a number of other pre- and post-randomisation measures of emotional health, quality of life, loneliness, problem behaviours, academic competence, service resource utilisation and adverse events. Results: A total of 250 children and young people from 98 schools were randomised: 127 to the intervention arm and 123 to the control arm. Intention-to-treat analysis of the main outcome measure showed a modest positive difference of 3.74 points (95% confidence interval -0.16 to 7.63 points, standardised effect size 0.18; p = 0.06) in favour of the intervention arm. Statistical significance increased in per-protocol analysis, with a modest positive difference (standardised effect size 0.21; p = 0.036). Cost-effectiveness of the intervention was found in reduced service use costs and a small increase in quality-adjusted life-years. Intervention fidelity and acceptability were positive. No intervention-related adverse events or effects were reported. Conclusions: The primary and pre-planned sensitivity analysis of the primary outcome consistently showed a positive clinical difference, with modest standardised effect sizes of between 0.15 and 0.21. There were positive health economics and qualitative findings, corroborated by the difference between arms for the majority of secondary outcomes, which were not statistically significant but favoured the intervention arm. Post hoc additional analysis was exploratory and was not used in drawing this conclusion. Given the small positive change, LEGO® based therapy for children and young people with autism spectrum disorder in schools should be considered. Limitations: The primary outcome measure was completed by an unblinded teacher (rather than by the facilitator). Future work: The study team recommends future research into LEGO® based therapy, particularly in school environments. Trial registration: This trial is registered as ISRCTN64852382. Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Public Health Research programme (NIHR award ref: 15/49/32) and is published in full in Public Health Research; Vol. 11, No. 12. See the NIHR Funding and Awards website for further award information.
Autism spectrum disorder is characterised by difficulties with social relationships and communication, which can make it difficult to make friends. Social skills training is commonly used to help children and young people learn different social skills, but some children and young people do not enjoy these therapies. LEGO® (LEGO System A/S, Billund, Denmark) based therapy takes a new approach by focusing on making the process interesting and fun. This research investigated the effect of LEGO® based therapy groups in schools on the social and emotional abilities of children and young people with autism spectrum disorder. It was a randomised controlled trial, so each school that was taking part was randomly chosen to provide either usual support (from the school or NHS services) or 12 sessions of LEGO® based therapy with a trained school staff member as well as usual support. Children and young people played one of three roles the 'engineer' (gives instructions), the 'supplier' (finds the pieces) or the 'builder' (builds the model) and worked together. Questionnaires completed by children and young people, their parents/guardians and teachers were used to look at the intervention's effects. The main objective was to see if there was a change in social skills measured by a teacher-completed questionnaire. Results showed that the social skills of children and young people in the LEGO® based therapy groups did improve a little. We found that the intervention is not very costly for schools to run. Many parents/guardians and teachers thought that the intervention was beneficial and that the children and young people enjoyed it.

(1) Background: Dementia and mild cognitive impairment (MCI) are still underdiagnosed in the general population. Impaired odor identification has been identified as an early marker of MCI and dementia. We aim to investigate whether short tasks, in which simple forms must be assembled from single building blocks based on a template or while considering specific re-strictions, could increase the diagnostic quality of established cognitive screening tests in detecting MCI or dementia. (2) Methods: A brief assembly test, where participants had to assemble simple animal shapes from Lego® Duplo® building blocks, the Frontal Assessment Battery, and the Mini-Mental State Exam (MMSE) were administered to a consecutive series of 197 patients (89 with mild dementia, 62 with mild cognitive impairment, and 46 without cognitive impairment) referred for neuropsychological testing. (3) Results: Both participants with dementia and with MCI performed badly in the assembly tasks. The assembly tasks and the Frontal Assessment Battery were substantially correlated. Complementing MMSE scores with the assembly tasks improved the diagnostic accuracy of individuals with dementia and MCI. (4) Conclusions: People with suspected dementia or MCI may already benefit from simple assembly tasks. Although these tests require little additional time, they can notably increase sensitivity for dementia or MCI.
RESUMO
Supporting student development of clear science communication skills is critically important and incredibly challenging. In this activity, to help students understand the importance of clear written communication, students work in pairs with LEGO bricks. One student with a completed LEGO structure describes a small LEGO construction, directing a second student to build it, sight unseen. This exercise serves three aims. First, it acts as an icebreaker in the beginning of this writing-intensive course; second, it prompts thinking about the features of clear communication; and finally, it highlights challenges in written communication. The exercise is followed by a short debrief and an in-class writing assignment. Most students found the exercise to be enjoyable and useful and advised including it in future course offerings. With modifications, it also runs well in an online format, and is easily adaptable to many other course contexts.
RESUMO
Antibody-drug conjugates (ADCs) have exciting possibilities in targeted tumor therapy. However, in the existing ADC preparation processes, the random attachment of the payloads to the antigen-binding fragments (Fab) greatly increases the risk of disrupting its antigen recognition ability, while the drug-antibody ratio (DAR) is low, leading to a cumbersome preparation process and low drug delivery efficiency. Herein, poly(glutamic acid) is used to expand the number of drug binding sites, based on the "click chemistry" of azide and DBCO, and the high affinity of Fc-III-4C peptide to the crystalline fragment (Fc) of the monoclonal antibodies. Various antibody-polymer-drug conjugates are obtained with ultrahigh DAR using this organic-solvent-free "Lego-like" modular construction. Among them, aHER2-P-MMAE with DAR of 41.6 achieves tumor growth inhibition (TGI) of 99.7% for both medium-sized and large SKOV-3 ovarian tumors, and aPDL1-P-MMAE (DAR = 40.7) achieves TGI of 98.5% for MC38 colon tumors. In summary, a universal platform is created to prepare Fab-nondestructive ADCs with ultrahigh DAR, which can be used to develop precision medicine for personalized anticancer therapy.

Anxiety is a common comorbidity for individuals with ASD, and there is some preliminary data about the efficacy of physical exercise to alleviate anxiety. However, we are not aware of any studies that have compared the effects of a physical exercise program on anxiety in underserved children with ASD using a randomized controlled research design. This paper describes a method to evaluate and compare the efficacy of an 8-week physical exercise intervention with a sedentary play intervention to alleviate anxiety in young children with autism spectrum disorders (ASD) from underserved backgrounds. We assessed anxiety and its physical symptoms using the parent-rated Child Behavior Checklist DSM-5 anxiety (CBCL DSM-5) subscale, the child-rated Screen for Childhood Anxiety Related Emotional Disorder (SCARED), the parent-rated Child's Sleep Habits Questionnaire (CSHQ), and salivary cortisol. We also utilized the Physical Activity Questionnaire for Older Children (PAQ-C) to assess physical activity level and identify compounds. Unique components of this study include: â¢Implementation of novel physical exercise and sedentary play interventions that have been designed for children with ASD.â¢Recruitment of predominantly underserved and non-English speaking families.
RESUMO
Over the years, several interventions have been implemented, including Lego® Therapy, with the aim of supporting and implementing social and communication skills impairments in Autism Spectrum Disorders (ASD). Although recent studies have shown that the ability to learn implicitly is preserved in ASDs, no study related to Lego® Therapy has analyzed whether and how this training can also affect aspects not directly treated. In this study, we report a first attempt of assessment of Lego® Therapy's effect on the specific area of cognitive skills in an ASD child. Over a period of 12 months, a child with ASD had weekly meetings with an expert operator of Lego® aiming to improve the child's ability to communicate, reduce impulsiveness and hyper verbalism, and encourage pro-social behavior. The intervention resulted in positive outcomes that were assessed after 12 months.
RESUMO
Roots are the hidden parts of plants, anchoring their above-ground counterparts in the soil. They are responsible for water and nutrient uptake and for interacting with biotic and abiotic factors in the soil. The root system architecture (RSA) and its plasticity are crucial for resource acquisition and consequently correlate with plant performance while being highly dependent on the surrounding environment, such as soil properties and therefore environmental conditions. Thus, especially for crop plants and regarding agricultural challenges, it is essential to perform molecular and phenotypic analyses of the root system under conditions as near as possible to nature (#asnearaspossibletonature). To prevent root illumination during experimental procedures, which would heavily affect root development, Dark-Root (D-Root) devices (DRDs) have been developed. In this article, we describe the construction and different applications of a sustainable, affordable, flexible, and easy to assemble open-hardware bench-top LEGO® DRD, the DRD-BIBLOX (Brick Black Box). The DRD-BIBLOX consists of one or more 3D-printed rhizoboxes, which can be filled with soil while still providing root visibility. The rhizoboxes sit in a scaffold of secondhand LEGO® bricks, which allows root development in the dark and non-invasive root tracking with an infrared (IR) camera and an IR light-emitting diode (LED) cluster. Proteomic analyses confirmed significant effects of root illumination on barley root and shoot proteomes. Additionally, we confirmed the significant effect of root illumination on barley root and shoot phenotypes. Our data therefore reinforces the importance of the application of field conditions in the lab and the value of our novel device, the DRD-BIBLOX. We further provide a DRD-BIBLOX application spectrum, spanning from investigating a variety of plant species and soil conditions and simulating different environmental conditions and stresses, to proteomic and phenotypic analyses, including early root tracking in the dark.
RESUMO
This study aimed to better understand the factors influencing the provision of sexuality-related post-stroke rehabilitation services by clinicians on different sites and to explore strategies to improve post-stroke rehabilitation services with stakeholders. A qualitative study with co-design methods was conducted with 20 clinicians from five post-stroke rehabilitation centers in Canada, 1 manager and 1 patient-partner. Participants either took part in a focus group or in sessions of an adapted version of the LEGO Serious Play method to explore influencing factors and strategies of improvement in relation to post-stroke sexual rehabilitation services. Thematic analysis was conducted semi-deductively using the Theoretical Domains Framework (TDF), the Capability, Opportunity, Motivation and Behaviour (COM-B) system and the Behaviour Change Wheel (BCW). A total of twenty factors pertaining either to the categories of Capability (n = 8; e.g., Sexual rehabilitation procedural knowledge), Motivation (n = 4; e.g., Professional boundaries) or Opportunity (n = 8; e.g., Workload) were perceived as influencing provision of sexual rehabilitation services by participants. A theoretical model was conceptualized. Strategies (n = 10) were categorized in concordance with the BCW as Training (n = 1), Enablement (n = 5) or Environmental restructuring (n = 4). This study showed that factors influencing provision of post-stroke rehabilitation services were numerous and interrelated, and that various strategies aiming either clinicians or the rehabilitation environment would be relevant to improve services. This study will help guide the design and implementation of future interventions studies aiming at improving post-stroke sexual rehabilitation services.
RESUMO
Lego® Serious Play® is a guided workshop in which participants construct Lego creations to represent symbolic and metaphorical ideas in response to assignments. How to encourage inexperienced debriefers to concentrate on dialogue and communications strategies rather than engage in an unstructured debate on technical or behavioral abilities is one of the main challenges in training people to debrief a high-fidelity simulation session. We explore the use of Lego bricks in this study to build straightforward, standardised situations that debriefers in training can use to practice leading discussion. With this method, the different debriefing methodologies may be practiced focusing exclusively on method and dialogue, without getting involved or having to concentrate on the technical aspects.
RESUMO
We present here two accessible ways for enhanced understanding of complex biological structures and their function in undergraduate Biology and Biochemistry classrooms. These methods can be applied for in-class instruction as well as for remote lessons, as they are cheap, easily available and easy to implement. LEGO® bricks and MERGE CUBE based augmented reality can be applied to make three-dimensional representation for any structure available on PDB. We envisage these techniques to be useful for students when visualizing simple stereochemical problems or complex pathway interactions.
