text: In the present study, essential and nonessential metal content and biomarker
responses were investigated in the intestine of fish collected from the areas
polluted by mining. Our objective was to determine metal and biomarker levels
in tissue responsible for dietary intake, which is rarely studied in water pollution
research. The study was conducted in the Bregalnica River, reference location,
and in the Zletovska and Kriva Rivers (the Republic of North Macedonia), which
are directly influenced by the active mines Zletovo and Toranica, respectively.
Biological responses were analyzed in Vardar chub (Squalius vardarensis; Karaman,
1928), using for the first time intestinal cytosol as a potentially toxic cell
fraction, since metal sensitivity is mostly associated with cytosol. Cytosolic
metal levels were higher in fish under the influence of mining (Tl, Li, Cs, Mo,
Sr, Cd, Rb, and Cu in the Zletovska River and Cr, Pb, and Se in the Kriva River
compared to the Bregalnica River in both seasons). The same trend was evident
for total proteins, biomarkers of general stress, and metallothioneins, biomarkers
of metal exposure, indicating cellular disturbances in the intestine, the primary
site of dietary metal uptake. The association of cytosolic Cu and Cd at all locations
pointed to similar pathways and homeostasis of these metallothionein-binding metals.
Comparison with other indicator tissues showed that metal concentrations were
higher in the intestine of fish from mining-affected areas than in the liver and
gills. In general, these results indicated the importance of dietary metal pathways,
and cytosolic metal fraction in assessing pollution impacts in freshwater ecosystems.

text: Current methods for assessing cell proliferation in 3D scaffolds rely on changes
in metabolic activity or total DNA, however, direct quantification of cell number
in 3D scaffolds remains a challenge. To address this issue, we developed an unbiased
stereology approach that uses systematic-random sampling and thin focal-plane
optical sectioning of the scaffolds followed by estimation of total cell number
(StereoCount). This approach was validated against an indirect method for measuring
the total DNA (DNA content); and the Bürker counting chamber, the current reference
method for quantifying cell number. We assessed the total cell number for cell
seeding density (cells per unit volume) across four values and compared the methods
in terms of accuracy, ease-of-use and time demands. The accuracy of StereoCount
markedly outperformed the DNA content for cases with ~ 10,000 and ~ 125,000 cells/scaffold.
For cases with ~ 250,000 and ~ 375,000 cells/scaffold both StereoCount and DNA
content showed lower accuracy than the Bürker but did not differ from each other.
In terms of ease-of-use, there was a strong advantage for the StereoCount due
to output in terms of absolute cell numbers along with the possibility for an
overview of cell distribution and future use of automation for high throughput
analysis. Taking together, the StereoCount method is an efficient approach for
direct cell quantification in 3D collagen scaffolds. Its major benefit is that
automated StereoCount could accelerate research using 3D scaffolds focused on
drug discovery for a wide variety of human diseases.

text: Singlet oxygen (1O2) formation is now recognised as a key aspect of non-aqueous
oxygen redox chemistry. For identifying 1O2, chemical trapping via 9,10-dimethylanthracene
(DMA) to form the endoperoxide (DMA-O2) has become the mainstay method due to
its sensitivity, selectivity, and ease of use. While DMA has been shown to be
selective for 1O2, rather than forming DMA-O2 with a wide variety of potentially
reactive O-containing species, false positives might hypothetically be obtained
in the presence of previously overlooked species. Here, we first give unequivocal
direct spectroscopic proof by the 1O2-specific near infrared (NIR) emission at
1270 nm for the previously proposed 1O2 formation pathways, which centre around
superoxide disproportionation. We then show that peroxocarbonates, common intermediates
in metal-O2 and metal carbonate electrochemistry, do not produce false-positive
DMA-O2. Moreover, we identify a previously unreported 1O2-forming pathway through
the reaction of CO2 with superoxide. Overall, we give unequivocal proof for 1O2
formation in non-aqueous oxygen redox and show that chemical trapping with DMA
is a reliable method to assess 1O2 formation.

text: Imaging of the immunological synapse (IS) between dendritic cells (DCs) and
T cells in suspension is hampered by suboptimal alignment of cell-cell contacts
along the vertical imaging plane. This requires optical sectioning that often
results in unsatisfactory resolution in time and space. Here, we present a workflow
where DCs and T cells are confined between a layer of glass and polydimethylsiloxane
(PDMS) that orients the cells along one, horizontal imaging plane, allowing for
fast en-face-imaging of the DC-T cell IS.

text: 'When crawling through the body, leukocytes often traverse tissues that are
densely packed with extracellular matrix and other cells, and this raises the
question: How do leukocytes overcome compressive mechanical loads? Here, we show
that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness
requires neither force sensing via the nucleus nor adhesive interactions with
a substrate. Upon global compression of the cell body as well as local indentation
of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into
dot-like structures, providing activation platforms for Arp2/3 nucleated actin
patches. These patches locally push against the external load, which can be obstructing
collagen fibers or other cells, and thereby create space to facilitate forward
locomotion. We show in vitro and in vivo that this WASp function is rate limiting
for ameboid leukocyte migration in dense but not in loose environments and is
required for trafficking through diverse tissues such as skin and lymph nodes.'

text: 5-Carboxycytosine (5caC) is a rare epigenetic modification found in nucleic
acids of all domains of life. Despite its sparse genomic abundance, 5caC is presumed
to play essential regulatory roles in transcription, maintenance and base-excision
processes in DNA. In this work, we utilize nuclear magnetic resonance (NMR) spectroscopy
to address the effects of 5caC incorporation into canonical DNA strands at multiple
pH and temperature conditions. Our results demonstrate that 5caC has a pH-dependent
global destabilizing and a base-pair mobility enhancing local impact on dsDNA,
albeit without any detectable influence on the ground-state B-DNA structure. Measurement
of hybridization thermodynamics and kinetics of 5caC-bearing DNA duplexes highlighted
how acidic environment (pH 5.8 and 4.7) destabilizes the double-stranded structure
by ∼10–20 kJ mol–1 at 37 °C when compared to the same sample at neutral pH. Protonation
of 5caC results in a lower activation energy for the dissociation process and
a higher barrier for annealing. Studies on conformational exchange on the microsecond
time scale regime revealed a sharply localized base-pair motion involving exclusively
the modified site and its immediate surroundings. By direct comparison with canonical
and 5-formylcytosine (5fC)-edited strands, we were able to address the impact
of the two most oxidized naturally occurring cytosine derivatives in the genome.
These insights on 5caC’s subtle sensitivity to acidic pH contribute to the long-standing
questions of its capacity as a substrate in base excision repair processes and
its purpose as an independent, stable epigenetic mark.

text: Tension of the actomyosin cell cortex plays a key role in determining cell–cell
contact growth and size. The level of cortical tension outside of the cell–cell
contact, when pulling at the contact edge, scales with the total size to which
a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)].
Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic
relationship only applies to a narrow range of cortical tension increase and that
above a critical threshold, contact size inversely scales with cortical tension.
This switch from cortical tension increasing to decreasing progenitor cell–cell
contact size is caused by cortical tension promoting E-cadherin anchoring to the
actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin
at the contact. After tension-mediated E-cadherin stabilization at the contact
exceeds a critical threshold level, the rate by which the contact expands in response
to pulling forces from the cortex sharply drops, leading to smaller contacts at
physiologically relevant timescales of contact formation. Thus, the activity of
cortical tension in expanding cell–cell contact size is limited by tension-stabilizing
E-cadherin–actin complexes at the contact.

text: The mammalian neocortex is composed of diverse neuronal and glial cell classes
that broadly arrange in six distinct laminae. Cortical layers emerge during development
and defects in the developmental programs that orchestrate cortical lamination
are associated with neurodevelopmental diseases. The developmental principle of
cortical layer formation depends on concerted radial projection neuron migration,
from their birthplace to their final target position. Radial migration occurs
in defined sequential steps, regulated by a large array of signaling pathways.
However, based on genetic loss-of-function experiments, most studies have thus
far focused on the role of cell-autonomous gene function. Yet, cortical neuron
migration in situ is a complex process and migrating neurons traverse along diverse
cellular compartments and environments. The role of tissue-wide properties and
genetic state in radial neuron migration is however not clear. Here we utilized
mosaic analysis with double markers (MADM) technology to either sparsely or globally
delete gene function, followed by quantitative single-cell phenotyping. The MADM-based
gene ablation paradigms in combination with computational modeling demonstrated
that global tissue-wide effects predominate cell-autonomous gene function albeit
in a gene-specific manner. Our results thus suggest that the genetic landscape
in a tissue critically affects the overall migration phenotype of individual cortical
projection neurons. In a broader context, our findings imply that global tissue-wide
effects represent an essential component of the underlying etiology associated
with focal malformations of cortical development in particular, and neurological
diseases in general.

text: In eukaryotes, clathrin-coated vesicles (CCVs) facilitate the internalization
of material from the cell surface as well as the movement of cargo in post-Golgi
trafficking pathways. This diversity of functions is partially provided by multiple
monomeric and multimeric clathrin adaptor complexes that provide compartment and
cargo selectivity. The adaptor-protein assembly polypeptide-1 (AP-1) complex operates
as part of the secretory pathway at the trans-Golgi network (TGN), while the AP-2
complex and the TPLATE complex jointly operate at the plasma membrane to execute
clathrin-mediated endocytosis. Key to our further understanding of clathrin-mediated
trafficking in plants will be the comprehensive identification and characterization
of the network of evolutionarily conserved and plant-specific core and accessory
machinery involved in the formation and targeting of CCVs. To facilitate these
studies, we have analyzed the proteome of enriched TGN/early endosome-derived
and endocytic CCVs isolated from dividing and expanding suspension-cultured Arabidopsis
(Arabidopsis thaliana) cells. Tandem mass spectrometry analysis results were validated
by differential chemical labeling experiments to identify proteins co-enriching
with CCVs. Proteins enriched in CCVs included previously characterized CCV components
and cargos such as the vacuolar sorting receptors in addition to conserved and
plant-specific components whose function in clathrin-mediated trafficking has
not been previously defined. Notably, in addition to AP-1 and AP-2, all subunits
of the AP-4 complex, but not AP-3 or AP-5, were found to be in high abundance
in the CCV proteome. The association of AP-4 with suspension-cultured Arabidopsis
CCVs is further supported via additional biochemical data.

text: Immune cells are constantly on the move through multicellular organisms to
explore and respond to pathogens and other harmful insults. While moving, immune
cells efficiently traverse microenvironments composed of tissue cells and extracellular
fibers, which together form complex environments of various porosity, stiffness,
topography, and chemical composition. In this protocol we describe experimental
procedures to investigate immune cell migration through microenvironments of heterogeneous
porosity. In particular, we describe micro-channels, micro-pillars, and collagen
networks as cell migration paths with alternative pore size choices. Employing
micro-channels or micro-pillars that divide at junctions into alternative paths
with initially differentially sized pores allows us to precisely (1) measure the
cellular translocation time through these porous path junctions, (2) quantify
the cellular preference for individual pore sizes, and (3) image cellular components
like the nucleus and the cytoskeleton. This reductionistic experimental setup
thus can elucidate how immune cells perform decisions in complex microenvironments
of various porosity like the interstitium. The setup further allows investigation
of the underlying forces of cellular squeezing and the consequences of cellular
deformation on the integrity of the cell and its organelles. As a complementary
approach that does not require any micro-engineering expertise, we describe the
usage of three-dimensional collagen networks with different pore sizes. Whereas
we here focus on dendritic cells as a model for motile immune cells, the described
protocols are versatile as they are also applicable for other immune cell types
like neutrophils and non-immune cell types such as mesenchymal and cancer cells.
In summary, we here describe protocols to identify the mechanisms and principles
of cellular probing, decision making, and squeezing during cellular movement through
microenvironments of heterogeneous porosity.

text: "This article investigates library-related documents written by Gerard van
Swieten (1700–72) during his tenure as Library Prefect in the Imperial Library
of Vienna (1745–72). Van Swieten’s time as Library Prefect is considered through
a textual analysis. Handwritten letters were deconstructed in terms of their appearance,
layout, and tone in order to mine them for meaning. Furthermore, the contents
were examined for library matters such as censorship, catalogues, and collection
development. The Imperial Court Library held a prominent role as a repository
for rare and valuable works, later becoming the National Library of Austria.\r\nGerard
van Swieten’s work as a librarian tends to be overlooked, perhaps because he is
better known as the private physician of Maria Theresia, as well as a medical
reformer. Nevertheless, he was a hard-working chief librarian deeply involved
in all aspects of librarianship. Van Swieten endorsed modern scientific works,
which were otherwise banned officially by the censorship commission, for the use
of scholars in the library, expanded the collection by acquiring books through
his network of scholars and publishers, and reissued library catalogues. He also
provided for the comfort of users in the library reading room, at a time when
such considerations were unusual. In conclusion, a proposal is made that van Swieten
viewed his role as librarian with some importance and pride."

text: 'The broad implementation of thermoelectricity requires high-performance and
low-cost materials. One possibility is employing surfactant-free solution synthesis
to produce nanopowders. We propose the strategy of functionalizing “naked” particles’
surface by inorganic molecules to control the nanostructure and, consequently,
thermoelectric performance. In particular, we use bismuth thiolates to functionalize
surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates
decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1)
carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement
and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity
reduction by small grain domains, grain boundaries and nanostructuration. Overall,
the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average
z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed
SnTe.'

text: Capacity, rate performance, and cycle life of aprotic Li–O2 batteries critically
depend on reversible electrodeposition of Li2O2. Current understanding states
surface-adsorbed versus solvated LiO2 controls Li2O2 growth as surface film or
as large particles. Herein, we show that Li2O2 forms across a wide range of electrolytes,
carbons, and current densities as particles via solution-mediated LiO2 disproportionation,
bringing into question the prevalence of any surface growth under practical conditions.
We describe a unified O2 reduction mechanism, which can explain all found capacity
relations and Li2O2 morphologies with exclusive solution discharge. Determining
particle morphology and achievable capacities are species mobilities, true areal
rate, and the degree of LiO2 association in solution. Capacity is conclusively
limited by mass transport through the tortuous Li2O2 rather than electron transport
through a passivating Li2O2 film. Provided that species mobilities and surface
growth are high, high capacities are also achieved with weakly solvating electrolytes,
which were previously considered prototypical for low capacity via surface growth.

text: Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact
electrification (CE) at the nanoscale, but converting KPFM voltage maps to charge
density maps is nontrivial due to long-range forces and complex system geometry.
Here we present a strategy using finite-element method (FEM) simulations to determine
the Green's function of the KPFM probe/insulator/ground system, which allows us
to quantitatively extract surface charge. Testing our approach with synthetic
data, we find that accounting for the atomic force microscope (AFM) tip, cone,
and cantilever is necessary to recover a known input and that existing methods
lead to gross miscalculation or even the incorrect sign of the underlying charge.
Applying it to experimental data, we demonstrate its capacity to extract realistic
surface charge densities and fine details from contact-charged surfaces. Our method
gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative
charge data over a range of experimental conditions, enabling quantitative CE
at the nanoscale.

text: Centrosomes play a crucial role during immune cell interactions and initiation
of the immune response. In proliferating cells, centrosome numbers are tightly
controlled and generally limited to one in G1 and two prior to mitosis. Defects
in regulating centrosome numbers have been associated with cell transformation
and tumorigenesis. Here, we report the emergence of extra centrosomes in leukocytes
during immune activation. Upon antigen encounter, dendritic cells pass through
incomplete mitosis and arrest in the subsequent G1 phase leading to tetraploid
cells with accumulated centrosomes. In addition, cell stimulation increases expression
of polo-like kinase 2, resulting in diploid cells with two centrosomes in G1-arrested
cells. During cell migration, centrosomes tightly cluster and act as functional
microtubule-organizing centers allowing for increased persistent locomotion along
gradients of chemotactic cues. Moreover, dendritic cells with extra centrosomes
display enhanced secretion of inflammatory cytokines and optimized T cell responses.
Together, these results demonstrate a previously unappreciated role of extra centrosomes
for regular cell and tissue homeostasis.

text: Muskelin (Mkln1) is implicated in neuronal function, regulating plasma membrane
receptor trafficking. However, its influence on intrinsic brain activity and corresponding
behavioral processes remains unclear. Here we show that murine Mkln1
knockout causes non-habituating locomotor activity, increased exploratory drive,
and decreased locomotor response to amphetamine. Muskelin deficiency impairs social
novelty detection while promoting the retention of spatial reference memory and
fear extinction recall. This is strongly mirrored in either weaker or stronger
resting-state functional connectivity between critical circuits mediating locomotor
exploration and cognition. We show that Mkln1 deletion
alters dendrite branching and spine structure, coinciding with enhanced AMPAR-mediated
synaptic transmission but selective impairment in synaptic potentiation maintenance.
We identify muskelin at excitatory synapses and highlight its role in regulating
dendritic spine actin stability. Our findings point to aberrant spine actin modulation
and changes in glutamatergic synaptic function as critical mechanisms that contribute
to the neurobehavioral phenotype arising from Mkln1
ablation.

text: The question of how RNA, as the principal carrier of genetic information evolved
is fundamentally important for our understanding of the origin of life. The RNA
molecule is far too complex to have formed in one evolutionary step, suggesting
that ancestral proto-RNAs (first ancestor of RNA) may have existed, which evolved
over time into the RNA of today. Here we show that isoxazole nucleosides, which
are quickly formed from hydroxylamine, cyanoacetylene, urea and ribose, are plausible
precursors for RNA. The isoxazole nucleoside can rearrange within an RNA-strand
to give cytidine, which leads to an increase of pairing stability. If the proto-RNA
contains a canonical seed-nucleoside with defined stereochemistry, the seed-nucleoside
can control the configuration of the anomeric center that forms during the in-RNA
transformation. The results demonstrate that RNA could have emerged from evolutionarily
primitive precursor isoxazole ribosides after strand formation.

text: Biological systems are the sum of their dynamic three-dimensional (3D) parts.
Therefore, it is critical to study biological structures in 3D and at high resolution
to gain insights into their physiological functions. Electron microscopy of metal
replicas of unroofed cells and isolated organelles has been a key technique to
visualize intracellular structures at nanometer resolution. However, many of these
methods require specialized equipment and personnel to complete them. Here, we
present novel accessible methods to analyze biological structures in unroofed
cells and biochemically isolated organelles in 3D and at nanometer resolution,
focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential
trafficking organelles, their detailed structural information is lacking due to
their poor preservation when observed via classical electron microscopy protocols
experiments. First, we establish a method to visualize CCVs in unroofed cells
using scanning transmission electron microscopy tomography, providing sufficient
resolution to define the clathrin coat arrangements. Critically, the samples are
prepared directly on electron microscopy grids, removing the requirement to use
extremely corrosive acids, thereby enabling the use of this method in any electron
microscopy lab. Secondly, we demonstrate that this standardized sample preparation
allows the direct comparison of isolated CCV samples with those visualized in
cells. Finally, to facilitate the high-throughput and robust screening of metal
replicated samples, we provide a deep learning analysis method to screen the “pseudo
3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes
accessible ways to examine the 3D structure of biological samples and provide
novel insights into the structure of plant CCVs.

text: 'Theoretical foundations of chaos have been predominantly laid out for finite-dimensional
dynamical systems, such as the three-body problem in classical mechanics and the
Lorenz model in dissipative systems. In contrast, many real-world chaotic phenomena,
e.g., weather, arise in systems with many (formally infinite) degrees of freedom,
which limits direct quantitative analysis of such systems using chaos theory.
In the present work, we demonstrate that the hydrodynamic pilot-wave systems offer
a bridge between low- and high-dimensional chaotic phenomena by allowing for a
systematic study of how the former connects to the latter. Specifically, we present
experimental results, which show the formation of low-dimensional chaotic attractors
upon destabilization of regular dynamics and a final transition to high-dimensional
chaos via the merging of distinct chaotic regions through a crisis bifurcation.
Moreover, we show that the post-crisis dynamics of the system can be rationalized
as consecutive scatterings from the nonattracting chaotic sets with lifetimes
following exponential distributions. '

text: The AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis that
initiates cytoplasmic maturation of the large ribosomal subunit. Drg1 releases
the shuttling maturation factor Rlp24 from pre-60S particles shortly after nuclear
export, a strict requirement for downstream maturation. The molecular mechanism
of release remained elusive. Here, we report a series of cryo-EM structures that
captured the extraction of Rlp24 from pre-60S particles by Saccharomyces cerevisiae
Drg1. These structures reveal that Arx1 and the eukaryote-specific rRNA expansion
segment ES27 form a joint docking platform that positions Drg1 for efficient extraction
of Rlp24 from the pre-ribosome. The tips of the Drg1 N domains thereby guide the
Rlp24 C terminus into the central pore of the Drg1 hexamer, enabling extraction
by a hand-over-hand translocation mechanism. Our results uncover substrate recognition
and processing by Drg1 step by step and provide a comprehensive mechanistic picture
of the conserved modus operandi of AAA-ATPases.
