The Effect of Ga-Ion Irradiation on Sub-Micron-Wavelength Spin Waves in Yttrium-Iron-Garnet Films.

We investigate the effect of focused-ion-beam (FIB) irradiation on spin waves with sub-micron wavelengths in Yttrium-Iron-Garnet (YIG) films. Time-resolved scanning transmission X-ray (TR-STXM) microscopy was used to image the spin waves in irradiated regions and deduce corresponding changes in the magnetic parameters of the film. We find that the changes of Gairradiation can be understood by assuming a few percent change in the effective magnetizationof the film due to a trade-off between changes in anisotropy and effective film thickness.

Identification of the subventricular tegmental nucleus as brainstem reward center.

Rewards are essential for motivation, decision-making, memory, and mental health. We identified the subventricular tegmental nucleus (SVTg) as a brainstem reward center. In mice, reward and its prediction activate the SVTg, and SVTg stimulation leads to place preference, reduced anxiety, and accumbal dopamine release.

Chronotropic effects of milrinone in a guinea pig ex vivo model: a pilot study to screen for new mechanisms of action.

Positive inotropic responses upon administration of milrinone, an inhibitor of the phosphodiesterase enzyme (PDE), involve a well-pronounced positive chronotropic effect. Here we tested whether milrinone evokes this chronotropic response solely by PDE inhibition or by a concerted action that involve additional pharmacological targets. Milrinone stimulated increases in heart rate were studied in right atrial preparations of guinea pig in the presence or absence of inhibitors of putative ancillary molecular pathways or ion channels: i.

Fifteen Years of NOVA Food-Processing Classification: "Friend or Foe" Among Sustainable Diet Indicators? A Scoping Review.

It has been 15 years since the introduction of the NOVA food-processing classification. While it was designed to identify ultra-processed foods linked to noncommunicable diseases, the NOVA system has a holistic concept that fits with sustainable nutrition. However, NOVA's connection to other sustainable diet indicators has not been thoroughly explored.

A cortico-subcortical loop for motor control via the pontine reticular formation.

Movement and locomotion are controlled by large neuronal circuits like the cortex-basal ganglia (BG)-thalamus loop. Besides the inhibitory thalamic output, the BG directly control movement via specialized connections with the brainstem. Whether other parallel loops with similar logic exist is presently unclear.

Survey of legislative frameworks and national recommendations governing paediatric maintenance haemodialysis in Europe.

Background: The application of international recommendations for paediatric maintenance haemodialysis (HD) could be strengthened by national laws or written recommendations. Our aim was therefore to describe the national rules governing paediatric maintenance HD in European countries.

Methods: A national representative, approved by the president of each paediatric nephrology society, was contacted in all 42 European countries to complete two online questionnaires.

An In Vivo Biostability Evaluation of ALD and Parylene-ALD Multilayers as Micro-Packaging Solutions for Small Single-Chip Implants.

Miniaturization of next-generation active neural implants requires novel micro-packaging solutions that can maintain their long-term coating performance in the body. This work presents two thin-film coatings and evaluates their biostability and in vivo performance over a 7-month animal study. To evaluate the coatings on representative surfaces, two silicon microchips with different surface microtopography are used.

Methods: We performed a cross-sectional real-world study based on users of the MASK-air® app who reported data for at least 3 different months.

Syndromic Retinitis Pigmentosa: A Narrative Review.

Retinitis pigmentosa (RP) encompasses inherited retinal dystrophies, appearing either as an isolated eye condition or as part of a broader systemic syndrome, known as syndromic RP. In these cases, RP includes systemic symptoms impacting other organs, complicating diagnosis and management. This review highlights key systemic syndromes linked with RP, such as Usher, Bardet-Biedl, and Alström syndromes, focusing on genetic mutations, inheritance, and clinical symptoms.

The Many Faces of Philadelphia: A Mature T-Cell Lymphoma with Variant Philadelphia-Translocation and Duplication of the Philadelphia Chromosome.

T-cell prolymphocytic leukemia (T-PLL) is a rare mature T-cell lymphoma that is usually associated with poor prognosis and short overall survival. We present a case of a 61-year-old woman presenting with T-PLL and the leukemic cells harboring (-breakpoint cluster region; -ABL protooncogene 1) fusion transcripts as the result of a variant of t(9;22)(q34;q11) called Philadelphia translocation: t(9;22;18)(q34;q11;q21). Sequencing revealed a rare transcript with an exon 6 breakpoint corresponding to e6a2 transcripts, which has thus far been reported in only 26 cases of leukemias.

Social psychology of context and in context: Understanding the temporal, spatial and embodied dimensions of contemporary geopolitics.

Critical voices within social psychology have, for some time, emphasized that context matters for understanding psychological phenomena and processes. This special issue examines what a social psychology of context, and in context, can contribute to understanding contemporary geopolitics. We argue that, in examining the interplay between social psychology and contemporary geopolitics, we can understand how geopolitical contexts shape psychological processes and how psychology, in turn, informs our understanding of geopolitical phenomena.

How Do Trematodes Induce Cancer? A Possible Evolutionary Adaptation of an Oncogenic Agent Transmitted by Flukes.

There is strong epidemiological evidence that development of various cancer types is linked to infection with flukes (Platyhelminthes: Trematoda) in Africa, Asia and the Middle East. The exact nature of the mechanism by which cancer is induced by these parasites is unknown. Here, we provide a new hypothesis suggesting that flukes are not the primary cause of cancer but act as vectors of cancer-inducing microbial pathogens.

Purging the Judiciary After a Transition: Between a Rock and a Hard Place.

Judges play a key role in the implementation of transitional justice mechanisms. Yet, less attention has been paid so far to the question of how to address their collaboration with non-democratic regimes. In theory, judges can be subjected to virtually all transitional justice mechanisms ranging from criminal prosecution and lustration to truth-seeking, or even amnesties.

Photosynthetic traits of along an ecological gradient and developmental stages.

Common reed () is a cosmopolitan species, though its dieback is a worldwide phenomenon. In order to assess the evolutionary role of phenotypic plasticity in a successful plant, the values and plasticity of photophysiological traits of were investigated in the Lake Fertő wetlands at 5 sites with different degrees of reed degradation and along a seasonal sequence. On the one hand, along the established ecological degradation gradient, photophysiological traits of changed significantly, affecting plant productivity, although no consistent gradient-type trends were observed.

Distinct Effects of Olanzapine Depot Treatment on Behavior and Muscarinic M1 Receptor Expression in the Triple-Hit Wisket Rat Model of Schizophrenia.

This study aimed to characterize the triple-hit schizophrenia-like model rats (Wisket) by the assessment of (1) behavioral parameters in different test conditions (reward-based Ambitus test and HomeManner system) for a prolonged period, (2) cerebral muscarinic M1 receptor (M1R) expression, and (3) the effects of olanzapine treatment on these parameters. Wistar (control) and Wisket rats were injected for three consecutive weeks with olanzapine depot (100 mg/kg) and spent 4 weeks in large cages with environmental enrichment (HomeManner). The vehicle-treated Wisket rats spent longer time awake with decreased grooming activity compared to controls, without changes in their active social behavior (sniffing, playing, fighting) obtained in HomeManner.

Probing the Signal Transduction Mechanism of the Light-Activated Adenylate Cyclase OaPAC Using Unnatural Amino Acid Mutagenesis.

OaPAC, the photoactivated adenylyl cyclase from , is composed of a blue light using FAD (BLUF) domain fused to an adenylate cyclase (AC) domain. Since both the BLUF and AC domains are part of the same protein, OaPAC is a model for understanding how the ultrafast modulation of the chromophore binding pocket caused by photoexcitation results in the activation of the output domain on the μs-s time scale. In the present work, we use unnatural amino acid mutagenesis to identify specific sites in the protein that are involved in transducing the signal from the FAD binding site to the ATP binding site.

Dynamic in vivo monitoring of granum structural changes of Ctenanthe setosa (Roscoe) Eichler during drought stress and subsequent recovery.

Investigating the effects of drought stress and subsequent recovery on the structure and function of chloroplasts is essential to understanding how plants adapt to environmental stressors. We investigated Ctenanthe setosa (Roscoe) Eichler, an ornamental plant that can tolerate prolonged drought periods (40 and 49 days of water withdrawal). Conventional biochemical, biophysical, physiological and (ultra)structural methods combined for the first time in a higher plant with in vivo small-angle neutron scattering (SANS) were used to characterize the alterations induced by drought stress and subsequent recovery.

Radio-tracking urban breeding birds: The importance of native vegetation.

As urban areas continue to expand globally, a deeper understanding of the functioning of urban green spaces is crucial for maintaining habitats that effectively support wildlife within our cities. Cities typically harbor a wide variety of nonnative vegetation, providing limited support for insect populations. The resulting scarcity of arthropods has been increasingly linked to adverse effects at higher trophic levels, such as the reduced reproductive success of insectivorous birds in urban environments.

Drug combinations targeting antibiotic resistance.

While the rise of antibiotic resistance poses a global health challenge, the development of new antibiotics has slowed down over the past decades. This turned the attention of researchers towards the rational design of drug combination therapies to combat antibiotic resistance. In this review we discuss how drug combinations can exploit the deleterious pleiotropic effects of antibiotic resistance and conclude that each drug interaction has its prospective therapeutic application.

Synthesis, HS releasing properties, antiviral and antioxidant activities and acute cardiac effects of nucleoside 5'-dithioacetates.

Hydrogen sulfide (HS) is an endogenous gasotransmitter with cardioprotective and antiviral effects. In this work, new cysteine-selective nucleoside-HS-donor hybrid molecules were prepared by conjugating nucleoside biomolecules with a thiol-activatable dithioacetyl group. 5'-Dithioacetate derivatives were synthesized from the canonical nucleosides (uridine, adenosine, cytidine, guanosine and thymidine), and the putative 5'-thio metabolites were also produced from uridine and adenosine.

An updated reference genome of Barbatula barbatula (Linnaeus, 1758).

This study presents an updated genome assembly of B. barbatula, contributing to the species' available genomic resources for downstream applications such as conservation genetics.

Anthropometric but not motor characteristics of young volleyball players were improved after a one-week-long intense training sports camp.

This study aimed to examine potential changes in the anthropometric and motor characteristics of volleyball players aged 17.98 ± 0.51 years after participation in a week-long sports camp.

A preliminary study of combined toxicity and underlying mechanisms of imidacloprid and cadmium coexposure using a multiomics integration approach.

Imidacloprid (IMI) and cadmium (Cd) have been shown to be harmful to mammals separately, but their combined toxicity to mammals remains largely unknown. In this study, biochemical analysis (oxidative stress and serum indicators of liver and kidney function), pathological sections and multiomics (metabolomics and transcriptomics) methods were used to investigate the changes and mechanisms of liver and kidney in mice coexposed to IMI and Cd. Biochemical analysis and pathological section results showed that oxidative stress, organ function, and cell damage were aggravated after the combination of the two methods.

Short communication: The importance of random effects in detecting purging of inbreeding depression: A model comparison in Pannon White rabbits.

Inbreeding depression (ID) is a well-documented phenomenon associated with reduced fitness and possible extinction. However, ID can be mitigated or even eliminated through the interplay of inbreeding and selection, a process known as purging. The aim of this study was to compare the predictive power of two commonly used approaches in models with and without random dam effects to detect purging (full and reduced models).
