Although therapy gets better the hepatocellular harm, it is associated with an increased price of steatosis. This study highlights the importance of a follow-up of liver integrity within these clients. © 2020 The Authors.Background Methylmalonic acidaemia with homocystinuria type C (cblC defect) is an inherited error of cobalamin k-calorie burning. Cobalamin lacking processing results in large quantities of methylmalonic acid and homocysteine. The latter is recognized as becoming a risk aspect for multiple sclerosis (MS). We report from the first instance of someone with comorbid cblC defect and MS. Case report This young male provided in the age 14 with a relapsing-remitting neurologic disorder associated with imaging alterations suggestive of MS. Treatment lead to a partial clinical improvement with vanishing of white matter lesions. Afterwards, the emergence of unanticipated clinical features resulted in a metabolic work-up, revealing a cobalamin intracellular problem. Genetic analysis disclosed a single variation in MMACHC (c.482G > A; p.Arg161Gln) and another splicing variant in PRDX1 (c.1-515G > T) that can cause the silencing associated with the wild-type MMACHC allele, therefore confirming the analysis of cblC problem. Although cblC therapy was effective, whenever 17-year-old he experienced a relapse of neurological symptoms. Further imaging and laboratory studies fundamentally supported the analysis of MS. Discussion Although the comorbid organization of MS and cblC in our patient may continue to be anecdotic, we suggest measuring Hcy and MMA amounts in younger patients with a relapsing-remitting demyelinating disorder, in order never to miss a cblC problem, that needs a particular and efficient treatment. © 2019 The Authors.Nontuberculous mycobacteria (NTM) attacks still represent a sizable set of insidious diseases difficult to deal with. Usually, immunocompromised patients suffer with NTM attacks, specially with respiratory involvement or disseminated diseases due to MAC (Mycobacterium avium complex). Right here we report an uncommon situation of Mycobacterium intracellulare disease involving epidermis and smooth muscle, manifested as a chronic cutaneous ulcer in an immunocompetent patient with a few comorbidities, including seizures. Precise diagnosis of species ended up being gotten with in vitro culture and RT-PCR (Real Time-Polymerase string Reaction) after a top medical suspicion. Despite the high complexity of NTM infections, you'll be able to achieve diagnostic goals through the right employment of current DNA-molecular technologies and a satisfactory management. © 2020 The Author(s).Hydatid illness is a parasitic zoonosis caused by Echinococcus granulosus larvae. Although it make a difference just about any an element of the body, liver and lung are the two organs where illness is most frequently detected. Subcutaneous hydatid cyst, which mainly develops additional to iatrogenic spillage of cyst contents into incision area during a visceral hydatid cyst surgery, accounts for only 1.5 percent of most instances of hydatid cyst. With only a small amount of reported situations, major involvement of subcutaneous tissue by hydatid cyst is a more rare event as compared using the secondary form. Subcutaneous hydatid cysts tend to include trunk area and limb roots, and mostly present as a slowly-growing, painless, mobile mass with a normal overlying skin. To our knowledge, only a few https://sb216763inhibitor.com/systemic-virus-like-contamination-in-youngsters-getting-radiation-treatment-regarding-acute-the-leukemia-disease/ instances of major subcutaneous hydatid cyst into the gluteal region are reported to date. Right here, we provide a 72-year-old farmer just who presented with a painless swelling within the gluteal region and identified as having primary subcutaneous hydatid cyst. © 2020 The Author(s).A 39-year-old man offered chief complaints of epistaxis and discomfort on the right cheek that lasted for about 2 months. A rather hard calcified black size with a foreign human anatomy was based in the right substandard nasal meatus. The client underwent endoscopic endonasal surgery and antimicrobial therapy, which included intravenous shot of Penicillin G 4 million units 6 times/day for 7 days and dental amoxicillin 1500 mg/day for six months. Actinomyces types ended up being identified from the calcified international body that calculated 5 mm in size. There clearly was no recurrence for 12 months following the surgery. Surgery and lasting high-dose penicillin for half a year or longer are essential because demise caused by poor compliance with antibiotics have already been reported in past scientific studies. © 2020 The Author(s).A 68-year-old man with past medical history of multiple cerebral infarctions provided to our medical center with subacute paresis. His vital signs on presentation were normal, along with his real examination, apart from their neurologic conclusions, was unremarkable. Neurologic examinations advised cerebellar ataxia. Laboratory evaluation verified good for person immunodeficiency virus (HIV) disease. Their CD4-positive lymphocyte count was 45/μL, and HIV-RNA was 2.3 × 105 copies/mL. Mind computed tomography (CT) scan revealed multiple mass lesions and mind magnetized resonance imaging (MRI) with fluid-attenuated inversion-recovery (FLAIR) revealed periventricular hyperintensities, which advised multiple cancerous lymphoma and HIV encephalopathy. His condition of consciousness had gradually worsened. Ultimately, he passed away 30 days after entry. The autopsy unexpectedly showed disseminated Kaposi's sarcoma (KS). KS lesions had been found in the belly, small bowel, liver, spleen, mesentery and lung area. KS had not been observed on his epidermis. Gross results disclosed numerous nodular lesions in each organ, and hematoxylin and eosin staining showed expansion of spindle cells with vascular proliferation.

Ultra-high field MRI offers many opportunities to expand the applications of MRI. In order for this to be realized, the technical problems associated with MRI at field strengths of 7 T and greater need to be solved or mitigated. This paper explores the use of new variations of composite RF pulses, named serial transmit excitation pulses (STEP), in contrast to parallel pulse techniques, in order to remove and/or mitigate the effects of non-uniform B1 excitation fields associated with the subject (eg the human brain). Several techniques based on STEP sequences are introduced and their application to human brain imaging is presented and evaluated.Phenotypic evolution through deep time is slower than expected from microevolutionary rates. This is the paradox of stasis. Previous models suggest stasis occurs because populations track adaptive peaks that remain relatively stable on million-year intervals, raising the equally perplexing question of why these large changes are so rare. Here, we consider the possibility that peaks can move more rapidly than populations can adapt, resulting in extinction. We model peak movement with explicit population dynamics, parameterized with published microevolutionary estimates. Allowing extinction greatly increases the parameter space of peak movements that yield the appearance of stasis observed in real data through deep time. Extreme peak displacements, regardless of their frequency, will rarely result in an equivalent degree of trait evolution because of extinction. Thus, larger peak displacements will rarely be inferred using trait data from extant species or observed in fossil records. Our work highlights population ecology as an important contributor to macroevolutionary dynamics, presenting an alternative perspective on the paradox of stasis, where apparent constraint on phenotypic evolution in deep time reflects our restricted view of the subset of earth's lineages that were fortunate enough to reside on relatively stable peaks.Polycyclic aromatic compounds consisting of four or five fused anthracene units were synthesized by PtCl2 -catalyzed cycloisomerization as novel long expanded helicenes. These compounds have helical structures with significant stacking of the terminal anthracene moieties at 0.33 nm interlayer distance. In the UV-vis and fluorescence spectra, the absorption and emission bands were red-shifted as the number of fused anthracene units was increased. The characteristic broad and long-lived emission bands of the long analogues are explained by the excimer-like stabilization of the excited state. These photophysical data as well as their cyclic voltammetric data are discussed on the basis of the π-conjugation and interlayer π⋅⋅⋅π interactions in the molecular structures and the molecular orbitals. The barrier and mechanism of helical inversion are also reported.
Unlike axolotls, the urodele Notophthalmus viridescens completes two metamorphoses and emerges from its aquatic environment to mate as a fully terrestrial adult. Larval and adult limb regeneration are commonly treated as roughly equivalent processes and, at least in part, as a recapitulation of embryonic development.

We compared larval limb development to regeneration of both larval and adult forelimbs and found that there are substantial differences in developmental pattern among larvae and adults. The larval pattern of preaxial dominance is absent in adult regenerates adult regenerates instead develop digits synchronously, and they do so before proximal autopodial elements have formed discrete aggregation zones. By contrast, larval regenerates follow a pattern of sequential digit formation from anterior to posterior, like their embryonic limb buds.

Based upon these morphological clues, we conclude that larval regenerates are unlikely to exhibit features of epimorphic regeneration seen in adults, but are more likely to represent a form of developmental regulation. Furthermore, we confirm that post-metamorphic limb regeneration is not a simple recapitulation of ontology at the morphological level. These distinctions may help to explain and interpret some experiments and observations of regeneration in neotenic or paedomorphic urodeles.

In Scotland, as elsewhere, there has been growing political and public interest in the function and process of parole accompanied by a lack of empirical research on the operation and effectiveness of parole.

Against the backdrop of a Scottish Government review of parole aimed, among other things, at improving the transparency of the process, the aim of the study was to explore the experiences of prisoners seeking early release on licence.

In conjunction with the Scottish Prison Service a national survey was conducted of 197 long-term prisoners who had experience of seeking early release on parole.

The survey revealed that prisoners did not have a clear understanding of parole and often did not feel fully engaged in the process.

It is argued that better support for prisoners prior to, during and following parole hearings might foster their increased engagement and alleviate some of the anxiety associated with the parole process.

Donor latent CMV infection increases cardiac-resident macrophages and T cells leading to increased inflammation, promoting allograft rejection. To investigate the role of cardiac-resident passenger macrophages in CMV-mediated TVS/CR, macrophages were depleted from latently ratCMV (RCMV)-infected donor allografts prior to transplantation. Latently RCMV-infected donor F344 rats were treated with clodronate, PBS, or control liposomes 3 days prior to cardiac transplant into RCMV-naïve Lewis recipients. Clodronate treatment significantly increased graft survival from post-operative day (POD)61 to POD84 and decreased TVS at rejection. To determine the kinetics of the effect of clodronate treatment's effect, a time study revealed that clodronate treatment significantly decreased macrophage infiltration into allograft tissues as early as POD14; altered allograft cytokine/chemokine protein levels, fibrosis development, and inflammatory gene expression profiles.

In the context of nondestructive testing (NDT), this paper proposes an inverse problem approach for the reconstruction of high-resolution ultrasonic images from full matrix capture (FMC) datasets. We build a linear model that links the FMC data, i.e. the signals collected from all transmitter-receiver pairs of an ultrasonic array, to the discretized reflectivity map of the inspected object. In particular, this model includes the ultrasonic waveform corresponding to the transducers response. Despite the large amount of data, the inversion problem is illposed. Therefore, a regularization strategy is proposed, where the reconstructed image is defined as the minimizer of a penalized least-squares cost function. A mixed penalization function is considered, which simultaneously enhances the sparsity of the image (in NDT, the reflectivity map is mostly zero except at the flaw locations) and its spatial smoothness (flaws may have some spatial extension). The proposed method is shown to outperform two well-known imaging methods the Total Focusing Method (TFM) and Excitelet. Numerical simulations with two close reflectors show that the proposed method improves the resolution limit defined by the Rayleigh criterion by a factor of four. Such high-resolution imaging capability is confirmed by experimental results obtained with side drilled holes in an aluminum sample.Human brain development is a complex and dynamic process caused by several factors such as genetics, sex hormones, and environmental changes. A number of recent studies on brain development have examined functional connectivity (FC) defined by the temporal correlation between time series of different brain regions. We propose to add the directional flow of information during brain maturation. To do so, we extract effective connectivity (EC) through Granger causality (GC) for two different groups of subjects, i.e., children and young adults. The motivation is that the inclusion of causal interaction may further discriminate brain connections between two age groups and help to discover new connections between brain regions. The contributions of this study are threefold. First, there has been a lack of attention to EC-based feature extraction in the context of brain development. To this end, we propose a new kernel-based GC (KGC) method to learn nonlinearity of complex brain network, where a reduced Sine hyperbolic polynomial (RSP) neural network was used as our proposed learner. Second, we used causality values as the weight for the directional connectivity between brain regions. Our findings indicated that the strength of connections was significantly higher in young adults relative to children. In addition, our new EC-based feature outperformed FC-based analysis from Philadelphia neurocohort (PNC) study with better discrimination of different age groups. Moreover, the fusion of these two sets of features (FC + EC) improved brain age prediction accuracy by more than 4%, indicating that they should be used together for brain development studies.When more than two elemental materials are present in a given object, material quantification may not be robust and accurate when the routine two-material decomposition scheme in current dual energy CT imaging is employed. In this work, we present an innovative scheme to accomplish accurate three-material decomposition with measurements from a dual energy differential phase contrast CT (DE-DPC-CT) acquisition. A DE-DPC-CT system was constructed using a grating interferometer and a photon counting CT imaging system with two energy bins. The DE-DPC-CT system can simultaneously measure both the imaginary and the real part of the complex refractive index to enable a three-material decomposition. https://www.selleckchem.com/products/etomoxir-na-salt.html Physical phantom with 21 material inserts were constructed and measured using DE-DPC-CT system. Results demonstrates excellent accuracy in elemental material quantification. For example, relative root-mean-square errors of 4.5% for calcium and 5.2% for iodine have been achieved using the proposed three-material decomposition scheme. Biological tissues with iodine inserts were used to demonstrate the potential utility of the proposed spectral CT imaging method. Experimental results showed that the proposed method correctly differentiates the bony structure, iodine, and the soft tissue in the biological specimen samples. A triple spectra CT scan was also performed to benchmark the performance of the DE-DPC-CT scan. Results demonstrated that the material decomposition from the DE-DPCCT has a much lower quantification noise than that from the triple spectra CT scan.Serious games are receiving increasing attention in the field of Cultural Heritage (CH) applications. A special field of CH and education is Intangible Cultural Heritage and particularly dance. Machine learning (ML) tools are necessary elements for the success of a serious game platform since they introduce intelligence in processing and analysis of users' interactivity. ML provides intelligent scoring and monitoring capabilities of the user's progress in a serious game platform. In this paper, we introduce a deep learning model for motion primitive classification. The model combines a convolutional processing layer with a bi-directional analysis module. This way, RGB information is efficiently handled by the hierarchies of convolutions, while the bi-directional properties of an LSTM model are retained. The resulting Convolutionally Enhanced Bi-directional LSTM (CEBi-LSTM) architecture is less sensitive to skeleton errors, occurring using low-cost sensors, such as Kinect, while simultaneously handling the high amount of detail when using RGB visual information.Bayesian networks are a class of popular graphical models that encode causal and conditional independence relations among variables by directed acyclic graphs (DAGs). We propose a novel structure learning method, annealing on regularized Cholesky score (ARCS), to search over topological sorts, or permutations of nodes, for a high-scoring Bayesian network. Our scoring function is derived from regularizing Gaussian DAG likelihood, and its optimization gives an alternative formulation of the sparse Cholesky factorization problem from a statistical viewpoint. We combine simulated annealing over permutation space with a fast proximal gradient algorithm, operating on triangular matrices of edge coefficients, to compute the score of any permutation. Combined, the two approaches allow us to quickly and effectively search over the space of DAGs without the need to verify the acyclicity constraint or to enumerate possible parent sets given a candidate topological sort. Through extensive numerical comparisons, we show that ARCS outperformed existing methods by a substantial margin, demonstrating its great advantage in structure learning of Bayesian networks from both observational and experimental data.

05). In addition, they were found to proliferate faster, secrete more IL-6 and express higher levels of the soluble IL-6R. IPF-HLF increased proliferation was inhibited by TCZ. Moreover, IPF-HLF derived supernatants induced both direct and indirect STAT3 activation that resulted in Smad3 phosphorylation and elevated Gremlin levels in N-HLFs. These effects were also successfully blocked by TCZ. CONCLUSIONS IPF-HLF paracrine signaling leads to IL-6R overexpression, which in turn, affects N-HLF survival. The IL-6/STAT3/Smad3 axis facilitates cellular responses that could potentially promote fibrotic disease. This interplay was successfully blocked by TCZ.BACKGROUND In response to high demand and the growing body of evidence for traditional and complementary therapies, the practice of integrative medicine and integrative healthcare has emerged where these therapies are blended with conventional healthcare. While there are a number of academic integrative healthcare centres worldwide, there are none in Australia. Western Sydney University will soon establish an academic integrative healthcare centre offering evidence-informed traditional and complementary therapies integrated with conventional healthcare in a research-based culture. The aim of this study was to explore healthcare consumers' views about the perceived need, advantages, and disadvantages of the proposed centre and its relevance to community-defined problems and health and service needs. METHODS Qualitative methods, informed by community-based participatory research, were used during 2017. Focus groups supplemented with semi-structured interviews were conducted with healthcare consumers. Participant participants desired greater integration of conventional healthcare with traditional and complementary therapies within a team-based, person-centred environment with assurances of safety and quality. Findings will be used to refine the model of care for an academic integrative healthcare centre in Western Sydney.BACKGROUND More than one-third of children under 3 years old are left behind at home due to parental migration in rural China, and we know very little about early childhood nutrition of left-behind children (LBC) because of the dearth of research. This study examined the association between parental migration and early childhood nutrition of LBC in rural China. METHODS We used repeated cross-sectional data of rural children aged 6-35 months who participated in two surveys in six counties of northern and southern China in 2013 and 2016 respectively. The length, weight, and hemoglobin concentration were measured by trained health-care workers blinded to parental migration status. Stunting, underweight, wasting, and anemia were identified with the standards recommended by WHO. Generalized linear regressions and multivariate logistic regressions were employed to explore the association between parental migration and these nutritional outcomes at each time point. RESULTS Two thousand three hundred thirty-six and 2 to early childhood nutrition of LBC in rural China. Continued nutritional support is needed for all rural children, especially interventions for preventing micronutrient deficiency. Programs for LBC are recommended to continue to focus on nutrition but pay more attention to other important health issues.BACKGROUND Lung cancer surgery is associated with a high incidence of postoperative pulmonary complications (PPCs). Preliminary evidence suggests that ERAS processes can reduce overall incidence of PPCs as short- and long-term recovery improved by supporting units to adopt evidence-based care. However, the evidence is inconclusive due to insufficient high-level studies in this research field. No well-designed, adequately powered, randomized controlled trials (RCTs) have investigated the effects of pulmonary rehabilitation based ERAS program (PREP) on post-operative pulmonary complications, pulmonary function, and health related quality of life following lung cancer surgery. METHODS The PREP trial is a pragmatic, investigator-initiated, multi-center, randomized controlled, parallel group, clinical trial. Five hundred patients scheduled for minimally invasive pulmonary resection at six hospitals in China will be randomized with concealed allocation to receive either i) a pre-operative assessment and an informatommendations in the surgical community. TRIAL REGISTRATION Chinese Clinical Trial Registry ChiCTR1900024646, 21 July 2019.BACKGROUND Aiming at the characteristics of nonlinear, multi-parameter, strong coupling and difficulty in direct on-line measurement of key biological parameters of marine low-temperature protease fermentation process, a soft-sensing modeling method based on artificial bee colony (ABC) and multiple least squares support vector machine (MLSSVM) inversion for marine protease fermentation process is proposed. METHODS Firstly, based on the material balance and the characteristics of the fermentation process, the dynamic "grey box" model of the fed-batch fermentation process of marine protease is established. The inverse model is constructed by analyzing the inverse system existence and introducing the characteristic information of the fermentation process. https://www.selleckchem.com/products/hs94.html Then, the inverse model is identified off-line using MLSSVM. Meanwhile, in order to reduce the model error, the ABC algorithm is used to correct the inverse model. Finally, the corrected inverse model is connected in series to the marine alkaline protease MP fermentation process to form a composite pseudo-linear system, thus, real-time on-line prediction of key biological parameters in fermentation process can be realized. RESULTS Taking the alkaline protease MP fermentation process as an example, the simulation results demonstrate that the soft-sensing modeling method can solve the real-time prediction problem of key biological parameters in the fermentation process on-line, and has higher accuracy and generalization ability than the traditional soft-sensing method of support vector machine. CONCLUSIONS The research provides a new method for soft-sensing modeling of key biological parameters in fermentation process, which can be extended to soft-sensing modeling of general nonlinear systems.

Motivated by the growing recognition of citrate as a central metabolite in a variety of biological processes associated with healthy and diseased cellular states, we have developed a series of high-performance genetically encoded citrate biosensors suitable for imaging of citrate concentrations in mammalian cells. The design of these biosensors was guided by structural studies of the citrate-responsive sensor histidine kinase and took advantage of the same conformational changes proposed to propagate from the binding domain to the catalytic domain. Following extensive engineering based on a combination of structure guided mutagenesis and directed evolution, we produced an inverse-response biosensor (ΔF/Fmin ≈ 18) designated Citroff1 and a direct-response biosensor (ΔF/Fmin ≈ 9) designated Citron1. https://www.selleckchem.com/products/arv-771.html report the X-ray crystal structure of Citron1 and demonstrate the utility of both biosensors for qualitative and quantitative imaging of steady-state and pharmacologically perturbed citrate concentrations in live cells.Single-atom catalysts (SACs) have attracted widespread interest for many catalytic applications because of their distinguishing properties. However, general and scalable synthesis of efficient SACs remains significantly challenging, which limits their applications. Here we report an efficient and universal approach to fabricating a series of high-content metal atoms anchored into hollow nitrogen-doped graphene frameworks (M-N-Grs; M represents Fe, Co, Ni, Cu, etc.) at gram-scale. The highly compatible doped ZnO templates, acting as the dispersants of targeted metal heteroatoms, can react with the incoming gaseous organic ligands to form doped metal-organic framework thin shells, whose composition determines the heteroatom species and contents in M-N-Grs. We achieved over 1.2 atom % (5.85 wt %) metal loading content, superior oxygen reduction activity over commercial Pt/C catalyst, and a very high diffusion-limiting current (6.82 mA cm-2). Both experimental analyses and theoretical calculations reveal the oxygen reduction activity sequence of M-N-Grs. Additionally, the superior performance in Fe-N-Gr is mainly attributed to its unique electron structure, rich exposed active sites, and robust hollow framework. This synthesis strategy will stimulate the rapid development of SACs for diverse energy-related fields.Liquid-phase transmission electron microscopy (TEM) has been recently applied to materials chemistry to gain fundamental understanding of various reaction and phase transition dynamics at nanometer resolution. However, quantitative extraction of physical and chemical parameters from the liquid-phase TEM videos remains bottlenecked by the lack of automated analysis methods compatible with the videos' high noisiness and spatial heterogeneity. Here, we integrate, for the first time, liquid-phase TEM imaging with our customized analysis framework based on a machine learning model called U-Net neural network. This combination is made possible by our workflow to generate simulated TEM images as the training data with well-defined ground truth. We apply this framework to three typical systems of colloidal nanoparticles, concerning their diffusion and interaction, reaction kinetics, and assembly dynamics, all resolved in real-time and real-space by liquid-phase TEM. #link# A diversity of properties for differently shaped anisotropic nanoparticles are mapped, including the anisotropic interaction landscape of nanoprisms, curvature-dependent and staged etching profiles of nanorods, and an unexpected kinetic law of first-order chaining assembly of concave nanocubes. These systems representing properties at the nanoscale are otherwise experimentally inaccessible. Compared to the prevalent image segmentation methods, U-Net shows a superior capability to predict the position and shape boundary of nanoparticles from highly noisy and fluctuating background-a challenge common and sometimes inevitable in liquid-phase TEM videos. We expect our framework to push the potency of liquid-phase TEM to its full quantitative level and to shed insights, in high-throughput and statistically significant fashion, on the nanoscale dynamics of synthetic and biological nanomaterials.The constant demand for novel functional materials calls for efficient strategies to accelerate the materials discovery, and crystal structure prediction is one of the most fundamental tasks along that direction. In addressing this challenge, generative models can offer new opportunities since they allow for the continuous navigation of chemical space via latent spaces. In this work, we employ a crystal representation that is inversion-free based on unit cell and fractional atomic coordinates and build a generative adversarial network for crystal structures. The proposed model is applied to generate the Mg-Mn-O ternary materials with the theoretical evaluation of their photoanode properties for high-throughput virtual screening (HTVS). The proposed generative HTVS framework predicts 23 new crystal structures with reasonable calculated stability and band gap. These findings suggest that the generative model can be an effective way to explore hidden portions of the chemical space, an area that is usually unreachable when conventional substitution-based discovery is employed.Supramolecular polymers are known to form strong and resilient hydrogels which can take up large amounts of water while exhibiting ease of processing and self-healing. They also possess similarities with networks of biological macromolecules. The combination of these features makes supramolecular polymers ideal candidates for studying mechanisms and consequences of self-assembly, which are relevant to biological materials. At the same time, this renders investigations of mixed hydrogels based on different supramolecular compounds necessary, since this substantially widens their applicability. Here, we address unusual viscoelastic properties of a class of binary hydrogels made by mixing fibrillar supramolecular polymers that are formed from two compounds 1,3,5-benzene-tricarboxamide decorated with aliphatic chains terminated by tetra(ethylene glycol) (BTA) and a 20 kg/mol telechelic poly(ethylene glycol) decorated with the same hydrogen bonding BTA motif on both ends (BTA-PEG-BTA). Using a suite of experimental and simulation techniques, we find that the respective single-compound-based supramolecular systems form very different networks which exhibit drastically different rheology.
