text: "Abstract\r\n Doxorubicin (DOX)
is a common drug in cancer chemotherapy, and its high DNA-binding affinity can
be harnessed in preparing DOX-loaded DNA nanostructures for targeted delivery
and therapeutics. Although DOX has been widely studied, the existing literature
of DOX-loaded DNA-carriers remains limited and incoherent. Here, based on an in-depth
spectroscopic analysis, we characterize and optimize the DOX loading into different
2D and 3D scaffolded DNA origami nanostructures (DONs). In our experimental conditions,
all DONs show similar DOX binding capacities (one DOX molecule per two to three
base pairs), and the binding equilibrium is reached within seconds, remarkably
faster than previously acknowledged. To characterize drug release profiles, DON
degradation and DOX release from the complexes upon DNase I digestion was studied.
For the employed DONs, the relative doses (DOX molecules released per unit time)
may vary by two orders of magnitude depending on the DON superstructure. In addition,
we identify DOX aggregation mechanisms and spectral changes linked to pH, magnesium,
and DOX concentration. These features have been largely ignored in experimenting
with DNA nanostructures, but are probably the major sources of the incoherence
of the experimental results so far. Therefore, we believe this work can act as
a guide to tailoring the release profiles and developing better drug delivery
systems based on DNA-carriers."

text: DNA origami nanostructures (DONs) are promising substrates for the
single-molecule investigation of biomolecular reactions and dynamics by in situ
atomic force microscopy (AFM). For this, they are typically immobilized on mica
substrates by adding millimolar concentrations of Mg2+ ions to the sample solution,
which enable the adsorption of the negatively charged DONs at the like-charged
mica surface. These non-physiological Mg2+ concentrations, however, present a
serious limitation in such experiments as they may interfere with the reactions
and processes under investigation. Therefore, we here evaluate three approaches
to efficiently immobilize DONs at mica surfaces under essentially Mg2+-free conditions.
These approaches rely on the pre-adsorption of different multivalent cations,
i.e., Ni2+, poly-l-lysine (PLL), and spermidine (Spdn). DON adsorption is studied
in phosphate-buffered saline (PBS) and pure water. In general, Ni2+ shows the
worst performance with heavily deformed DONs. For 2D DON triangles, adsorption
at PLL- and in particular Spdn-modified mica may outperform even Mg2+-mediated
adsorption in terms of surface coverage, depending on the employed solution. For
3D six-helix bundles, less pronounced differences between the individual strategies
are observed. Our results provide some general guidance for the immobilization
of DONs at mica surfaces under Mg2+-free conditions and may aid future in situ
AFM studies.

text: "Abstract\r\n Background\r\n
\ Hand amputation can have a truly debilitating impact on
the life of the affected person. A multifunctional myoelectric prosthesis controlled
using pattern classification can be used to restore some of the lost motor abilities.
However, learning to control an advanced prosthesis can be a challenging task,
but virtual and augmented reality (AR) provide means to create an engaging and
motivating training.\r\n \r\n Methods\r\n
\ In this study, we present a novel training framework that
integrates virtual elements within a real scene (AR) while allowing the view from
the first-person perspective. The framework was evaluated in 13 able-bodied subjects
and a limb-deficient person divided into intervention (IG) and control (CG) groups.
The IG received training by performing simulated clothespin task and both groups
conducted a pre- and posttest with a real prosthesis. When training with the AR,
the subjects received visual feedback on the generated grasping force. The main
outcome measure was the number of pins that were successfully transferred within
20 min (task duration), while the number of dropped and broken pins were also
registered. The participants were asked to score the difficulty of the real task
(posttest), fun-factor and motivation, as well as the utility of the feedback.\r\n
\ \r\n Results\r\n
\ The performance (median/interquartile range) consistently
increased during the training sessions (4/3 to 22/4). While the results were similar
for the two groups in the pretest, the performance improved in the posttest only
in IG. In addition, the subjects in IG transferred significantly more pins (28/10.5
versus 14.5/11), and dropped (1/2.5 versus 3.5/2) and broke (5/3.8 versus 14.5/9)
significantly fewer pins in the posttest compared to CG. The participants in IG
assigned (mean ± std) significantly lower scores to the difficulty compared to
CG (5.2 ± 1.9 versus 7.1 ± 0.9), and they highly rated the fun factor (8.7 ± 1.3)
and usefulness of feedback (8.5 ± 1.7).\r\n \r\n
\ Conclusion\r\n The
results demonstrated that the proposed AR system allows for the transfer of skills
from the simulated to the real task while providing a positive user experience.
The present study demonstrates the effectiveness and flexibility of the proposed
AR framework. Importantly, the developed system is open source and available for
download and further development.\r\n "

text: There is a distinct increase in the prevalence of depression with
the onset of puberty. The role of peripubertal testosterone levels in boys in
this context is insufficiently understood and may be modulated by a functional
polymorphism of the androgen receptor gene (AR), a variable number of CAG repeats.
Moreover, there is preliminary evidence that the relationship between testosterone,
CAG repeat length, and the severity of depressive symptoms may differ between
subclinical and overt depression, but this has neither been studied in a clinical
sample of adolescents with depression nor compared between subclinical and overt
depression in an adequately powered study. To investigate the relationship between
free testosterone, CAG repeat length of the AR, depression status (subclinical
vs. overt), and the severity of depressive symptoms, 118 boys treated as in- or
daycare patients at a single psychiatric hospital were studied. Of these, 73 boys
had at least mild depressive symptoms according to the Beck Depression Inventory-II
(BDI-II > 13). Higher-order moderation analysis in the multiple regression
framework revealed a constant relationship between free testosterone and depression
severity irrespective of the number of CAG repeats in adolescents with a BDI-II
score ≤ 13. In adolescents with a BDI-II score > 13, however, there was
a significant negative relationship between free testosterone and BDI-II score
in patients with <19 CAG repeats and a significant positive relationship
regarding free testosterone and BDI-II score in those with more than 28 CAG repeats,
even when considering important covariates. These results suggest that the effects
of testosterone on mood in male adolescents with depression depend on the genetic
make-up of the AR as well as on depression status. This complex relationship should
be considered by future studies addressing mental health issues against an endocrine
background and may, moreover, contribute to tailored treatment concepts in psychiatric
medicine, especially in adults.

text: '(1) Background: Evidence has accumulated that patients with anorexia
nervosa (AN) are at higher risk for vitamin D deficiency than healthy controls.
In epidemiologic studies, low 25(OH) vitamin D (25(OH)D) levels were associated
with depression. This study analyzed the relationship between 25(OH)D serum levels
in adolescent patients and AN and depressive symptoms over the course of treatment.
(2) Methods: 25(OH)D levels and depressive symptoms were analyzed in 93 adolescent
(in-)patients with AN from the Anorexia Nervosa Day patient versus Inpatient (ANDI)
multicenter trial at clinic admission, discharge, and 1 year follow up. Mixed
regression models were used to analyze the relationship between 25(OH)D levels
and depressive symptoms assessed by the Beck Depression Inventory (BDI-II). (3)
Results: Although mean 25(OH)D levels constantly remained in recommended ranges
(≥50 nmol/L) during AN treatment, levels decreased from (in)patient admission
to 1 year follow up. Levels of 25(OH)D were neither cross-sectionally, prospectively,
nor longitudinally associated with the BDI-II score. (4) Conclusions: This study
did not confirm that 25(OH)D levels are associated with depressive symptoms in
patients with AN. However, increasing risks of vitamin D deficiency over the course
of AN treatment indicate that clinicians should monitor 25(OH)D levels.'

text: AbstractAnorexia nervosa (AN) is a severe
eating disorder and often associated with altered humoral immune responses. However,
distinct B cell maturation stages in peripheral blood in adolescents with AN have
not been characterized. Treatment effects and the relationship between clinical
and B cell parameters are also not fully understood. Here we investigated the
phenotype of circulating B cell subsets and the relationship with body composition
in adolescents with AN before (T0, n = 24) and after 6 weeks (T1, n = 20) of treatment.
Using multi-parameter flow cytometry, we found increased percentages of antigen-experienced
B cells and plasmablasts in patients with AN compared to healthy controls (n = 20).
In contrast, percentages of CD1d+CD5+
B cells and transitional B cells with immunoregulatory roles were reduced at T0
and T1. These B cell frequencies correlated positively with fat mass, fat mass
index (FMI), free fat mass index, and body mass index standard deviation score.
In addition, scavenger-like receptor CD5 expression levels were downregulated
on transitional B cells and correlated with fat mass and FMI in AN. Our findings
that regulatory B cell subgroups were reduced in AN and their strong relationship
with body composition parameters point toward an impact of immunoregulatory B
cells in the pathogenesis of AN.

text: 'When joining lightweight parts of various materials, clinching is a cost
efficient solution. In a production line, the quality of a clinch point is primarily
controlled by measurement of dimensions, which are accessible from outside. However,
methods such as visual testing and measuring the bottom thickness as well as the
outer diameter are not able to deliver any information about the most significant
geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore,
ex-situ destructive methods such as microsectioning cannot detect elastic deformations
and cracks that close after unloading. In order to exceed the current limits,
a new non-destructive in-situ testing method for the clinching process is necessary.
This work proposes a concept to characterize clinch points in-situ by combining
two complementary non-destructive methods, namely, computed tomography (CT) and
ultrasonic testing. Firstly, clinch points with different geometrical characteristics
are analysed experimentally using ex-situ CT to get a highly spatially resolved
3D-image of the object. In this context, highly X-ray attenuating materials enhancing
the visibility of the sheet-sheet interface are investigated. Secondly, the test
specimens are modelled using finite element method (FEM) and a transient dynamic
analysis (TDA) is conducted to study the effect of the geometrical differences
on the deformation energy and to qualify the TDA as a fast in-situ non-destructive
method for characterizing clinch points at high temporal resolution. '

text: "Abstract\r\n Purpose\r\n
\ Studies about effects of lunch dietary Glycemic Index
(GI) on cognition of schoolchildren are scarce. Our previous CogniDo GI study
found no changes of cognition in the early postprandial phase after consumption
of two rice types with medium vs. high dietary GI for lunch (i.e., 45 min after
starting lunch). This study investigated whether the dietary GI of lunch has an
impact on cognition of schoolchildren in the late postprandial phase, 90 min after
lunch.\r\n \r\n Methods\r\n
\ A randomized, 2 × 2 crossover intervention study was conducted
at a comprehensive school with 5th and 6th grade students. Participants (n = 212)
were randomly assigned to either sequence 1 or 2. In the first period, participants
of sequence 1 received a dish with high GI rice (GI: 79), those of sequence 2
with medium GI rice (GI: 64)—in the second period, 1 week later, vice versa. Computer-based
cognitive testing was performed 90 min after lunch examining tonic alertness,
visual search and task switching, and working memory. Treatment effects and treatment
effects adjusted for estimated lunch glycemic load (GL) were analyzed using a
linear mixed model.\r\n \r\n Results\r\n
\ The selected cognitive parameters were not affected by
the GI of lunch 90 min after lunch, neither after intention-to-treat nor in the
per-protocol analysis. Adjustment for GL also did not change results.\r\n
\ \r\n Conclusion\r\n
\ The present study revealed no notable differences after
the consumption of two rice types with medium vs. high dietary GI for lunch in
children’s cognitive function in the late postprandial phase, 90 min after lunch.\r\n
\ \r\n Clinical trial
registration\r\n German Clinical Trials Register
(DRKS00013597); date of registration: 16/04/2018, retrospectively registered.\r\n

text: Orange-colored crystals of the oxoferrate tellurate K12+6xFe6Te4−xO27 [x=0.222(4)]
were synthesized in a potassium hydroxide hydroflux with a molar water–base ratio
n(H2O)/n(KOH) of 1.5 starting from Fe(NO3)3 ⋅ 9H2O, TeO2 and H2O2 at about 200 °C.
By using (NH4)2TeO4 instead of TeO2, a fine powder consisting of microcrystalline
spheres of K12+6xFe6Te4−xO27 was obtained. K12+6xFe6Te4−xO27 crystallizes in the
acentric cubic space group Iurn:x-wiley:09476539:media:chem202102464:chem202102464-math-0001
3d. [FeIIIO5] pyramids share their apical atoms in [Fe2O9] groups and two of their
edges with [TeVIO6] octahedra to form an open framework that consists of two loosely
connected, but not interpenetrating, chiral networks. The flexibility of the hinged
oxometalate network manifests in a piezoelectric response similar to that of LiNbO3.The
potassium cations are mobile in channels that run along the <111> directions and
cross in cavities acting as nodes. The ion conductivity of cold-pressed pellets
of ball-milled K12+6xFe6Te4−xO27 is 2.3×10^(−4) S ⋅ cm^(−1) at room temperature.
Magnetization measurements and neutron diffraction indicate antiferromagnetic
coupling in the [Fe2O9] groups.

text: To analyze the influence of suspension kinematics on tire wear, detailed
simulation models are required. In this study, a non-linear, flexible multibody
model of a rear axle system is built up in the simulation software MSC Adams/View.
The physical model comprises the suspension kinematics, compliance, and dynamics
as well as the non-linear behavior of the tire using the FTire model. FTire is
chosen because it has a separate tire tread model to compute the contact pressure
and friction force distribution in the tire contact patch. To build up the simulation
model, a large amount of data is needed. Bushings, spring, and damper characteristics
are modeled based on measurements. For the structural components (e.g., control
arms), reverse engineering techniques are used. The components are 3D-scanned,
reworked, and included as a modal reduced finite element (FE)-model using component
mode synthesis by Craig–Bampton. Finally, the suspension model is validated by
comparing the simulated kinematic and compliance characteristics to experimental
results. To investigate the interaction of suspension kinematics and tire wear,
straight line driving events, such as acceleration, driving with constant velocity,
and deceleration, are simulated with different setups of wheel suspension kinematics.
The influence of the setups on the resulting friction work between tire and road
is examined, and an exemplarily calculation of tire wear based on a validated
FTire tire model is carried out. The results demonstrate, on the one hand, that
the chosen concept of elasto-kinematic axle leads to a relatively good match with
experimental results and, on the other hand, that there are significant possibilities
to reduce tire wear by adjusting the suspension kinematics.

text: "Abstract\r\n Abductive reasoning
is a non-monotonic formalism stemming from the work of Peirce. It describes the
process of deriving the most plausible explanations of known facts. Considering
the positive version, asking for sets of variables as explanations, we study,
besides the problem of wether there exists a set of explanations, two explanation
size limited variants of this reasoning problem (less than or equal to, and equal
to a given size bound). In this paper, we present a thorough two-dimensional classification
of these problems: the first dimension is regarding the parameterized complexity
under a wealth of different parameterizations, and the second dimension spans
through all possible Boolean fragments of these problems in Schaefer’s constraint
satisfaction framework with co-clones (T. J. Schaefer. The complexity of satisfiability
problems. In Proceedings of the 10th Annual ACM Symposium on Theory of Computing,
May 1–3, 1978, San Diego, California, USA, R.J. Lipton, W.A. Burkhard, W.J. Savitch,
E.P. Friedman, A.V. Aho eds, pp. 216–226. ACM, 1978). Thereby, we almost complete
the parameterized complexity classification program initiated by Fellows et al.
(The parameterized complexity of abduction. In Proceedings of the Twenty-Sixth
AAAI Conference on Articial Intelligence, July 22–26, 2012, Toronto, Ontario,
Canada, J. Homann, B. Selman eds. AAAI Press, 2012), partially building on the
results by Nordh and Zanuttini (What makes propositional abduction tractable.
Artificial Intelligence, 172, 1245–1284, 2008). In this process, we outline a
fine-grained analysis of the inherent parameterized intractability of these problems
and pinpoint their FPT parts. As the standard algebraic approach is not applicable
to our problems, we develop an alternative method that makes the algebraic tools
partially available again."
