@article{65545, abstract = {{ABSTRACT Ligation of staple strands in DNA origami nanostructures (DONs) can yield enhanced structural stability in critical environments. This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.}}, author = {{Hacker, Konrad and Juricke, Emilia and Münch, Carolin and Suma, Antonio and Keller, Adrian Clemens and Zhang, Yixin}}, issn = {{1613-6810}}, journal = {{Small}}, publisher = {{Wiley}}, title = {{{Global Quantitative Analysis of Ligation Reactions in Self‐Assembled DNA Nanostructures at the Single‐Nick Level}}}, doi = {{10.1002/smll.202508136}}, year = {{2026}}, } @inbook{65549, author = {{Grimminger-Seidensticker, Elke and Ehrlenspiel, Felix and Hepperle, Lisa}}, booktitle = {{Schulsport.

A persistent challenge in current pharmacotherapy is the limited selectivity of active pharmaceutical ingredients, resulting in undesirable side effects. Smart drug delivery systems, which release encapsulated active pharmaceutical ingredients in response to specific stimuli, offer a potential solution by enabling controlled drug release. This approach can be particularly relevant for exploiting biochemical differences between extracellular and intracellular environments. In this study, self-immolative polydisulfide based polymers manufactured from dithiothreitol were processed into nanoparticle formulations to respond preferentially to elevated glutathione levels, which are characteristic of intracellular environments and are often increased in tumor cells. The influence of polymer chain length on the physicochemical properties of the resulting nanoparticles was investigated. Lumogen® Red was incorporated as a model substance to determine the loading capacity of the carrier system. Degradation was characterized using dynamic light scattering and asymmetric flow field-flow fractionation, as well as by imaging techniques such as atomic force microscopy. Selective release of the embedded substance was demonstrated at elevated glutathione concentrations, while no significant release was observed at extracellularly relevant levels (10 µM glutathione), where the behavior was comparable to the buffer control. Increased release was observed under intracellularly relevant conditions (2 – 10 mM glutathione). These findings support a redox-responsive behavior under intracellular-like conditions. The latter was proven for primary fibroblasts and the cancer cell lines BT-474, MCF-7 and SK-BR-3 by quantification of intracellular low molecular weight thiols. The nanoparticle uptake was confirmed in the investigated cell lines by visualization via confocal laser scanning microscopy. Via lysosomal staining it was shown that nanoparticles accumulate in lysosomes. Furthermore, the carrier system itself showed no cytotoxic properties in cell culture studies against the four different cell types. The developed system is a suitable and very promising smart drug delivery system in the context of controlled drug release.}}, author = {{Kramer, Maurice and Horky, Corinna and Völlmecke, Katharina and Mulac-Hahnen, Dennis and Herrmann, Fabian and Kuckling, Dirk and Langer, Klaus}}, issn = {{2949-8295}}, journal = {{Next Nanotechnology}}, keywords = {{Nanoparticles, Smart drug delivery, Controlled release, Self-immolative polymers, Tumor targeting}}, publisher = {{Elsevier BV}}, title = {{{Smart drug delivery systems for potential targeted cancer therapy: Exploiting increased glutathione levels in tumor microenvironments}}}, doi = {{10.1016/j.nxnano.2026.100510}}, volume = {{9}}, year = {{2026}}, } @article{45284, author = {{Webersen, Yvonne and Daud, Fardien}}, journal = {{MNU Journal}}, title = {{{Was steckt drin?

A linear increase in a exp with rising temperature is observed. The thermal expansion behaviour is modelled using Debye´s phonon dispersion.

An average value of Θ D of ≈905 ± 25 K is obtained, which is very close to our experimental results.

To this end, we consider different programs based on the restriction of the evolution to the set of separable (i.e., non-entangled) states, together with the discretization of the space of variables for numerical computations. As a first approach, we apply linear splitting methods to the restricted, continuous equations of motion derived from variational principles. We utilize an exchange interaction Hamiltonian to confirm that the numerical and analytical solutions coincide in the limit of small time steps. The application to different Hamiltonians shows the wide applicability of the method to detect dynamical entanglement. To avoid the derivation of analytical solutions for complex dynamics, we consider variational, numerical integration schemes, introducing a variational discretization for Lagrangians linear in velocities. Here, we examine and compare two approaches: one in which the system is discretized before the restriction is applied, and another in which the restriction precedes the discretization. We find that the ‘first-discretize-then-restrict’ method becomes numerically unstable, already for the example of an exchange-interaction Hamiltonian, which can be an important consideration for the numerical analysis of constrained quantum dynamics. Thereby, broadly applicable numerical tools, including their limitations, for studying entanglement over time are established for assessing the entangling power of processes that are used in quantum information theory.}}, author = {{Offen, Christian and Wembe Moafo, Boris Edgar and Ares, Laura and Sperling, Jan and Ober-Blöbaum, Sina}}, issn = {{1751-8113}}, journal = {{Journal of Physics A: Mathematical and Theoretical}}, number = {{22}}, publisher = {{IOP Publishing}}, title = {{{Numerical approaches to entangling dynamics from variational principles}}}, doi = {{10.1088/1751-8121/ae6d51}}, volume = {{59}}, year = {{2026}}, } @article{65847, abstract = {{Simulating vibronic spectra is a central task in physical chemistry, offering insight into important properties of molecules.

To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts.

We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states.

Exergaming offers a promising prophylactic intervention combining physical and cognitive training. The aim of the present study was to assess how exergaming alters the temporal trajectory of brain signal complexity at rest and during gameplay in older adults. Methods Twenty-eight healthy older adults participated in a 4-week exergaming intervention. Electroencephalography was recorded using 64 electrodes at rest (pre- and post-intervention) and during exergaming (pre-, mid-, and post-intervention). Brain signal complexity was quantified using multiscale entropy across 64 time scales on preprocessed signals. Results Post-intervention resting-state analysis revealed significant reductions at fine and increases at coarse scales in frontal, central, and posterior entropy. During gameplay, entropy declined widespread by mid-intervention, particularly at coarse scales over frontal, central and temporal regions. From mid- to post-intervention, the decline narrowed leaving a net pre-to-post reduction concentrated at coarse scales in these regions. Discussion Resting-state changes indicated a shift toward a younger brain profile, characterized by a transition from age-related increases in local processing to enhanced distributed processing, which may potentially mitigate the rise in neural modularity associated with aging. During gameplay, brain signal complexity decreased in week 2, followed by a modest change by week 4, consistent with the framework in which complexity initially streamlines and then adjusts toward a task-specific optimum. These findings suggest that exergaming can beneficially modulate brain complexity in older adults, offering the potential to reduce age-related neural decline and support healthy brain aging. }}, author = {{Piskin, Daghan Yüksel and Müller, Helen Martha and Skjæret-Maroni, Nina and Vereijken, Beatrix and Baumeister, Jochen}}, issn = {{1663-4365}}, journal = {{Frontiers in Aging Neuroscience}}, publisher = {{Frontiers Media SA}}, title = {{{Rewiring the aging brain: exergaming modulates brain complexity in older adults}}}, doi = {{10.3389/fnagi.2025.1748274}}, volume = {{17}}, year = {{2026}}, } @article{65935, author = {{Piskin, Daghan Yüksel and Cobani, Gjergji and Büchel, Daniel and Lehmann, Tim and Baumeister, Jochen}}, issn = {{0361-9230}}, journal = {{Brain Research Bulletin}}, publisher = {{Elsevier BV}}, title = {{{Brain complexity in motion: Multiscale entropy analysis on mobile EEG data to assess motor performance}}}, doi = {{10.1016/j.brainresbull.2026.111769}}, volume = {{236}}, year = {{2026}}, }
