The Asgard archaeal origins of Arf family GTPases involved in eukaryotic organelle dynamics.

The evolution of eukaryotes is a fundamental event in the history of life. The closest prokaryotic lineage to eukaryotes, the Asgardarchaeota, encode proteins previously found only in eukaryotes, providing insight into their archaeal ancestor. Eukaryotic cells are characterized by endomembrane organelles, and the Arf family GTPases regulate organelle dynamics by recruiting effector proteins to membranes upon activation.

The first insight into Acanthocephalus (Palaeacanthocephala) satellitome: species-specific satellites as potential cytogenetic markers.

Acanthocephalan parasites are often overlooked in many areas of research, and satellitome and cytogenetic analyzes are no exception. The species of the genus Acanthocephalus are known for their very small chromosomes with ambiguous morphology, which makes karyotyping difficult. In this study, we performed the first satellitome analysis of three Acanthocephalus species to identify species- and chromosome-specific satellites that could serve as cytogenetic markers.

The kinetics of uracil-N-glycosylase distribution inside replication foci.

Mismatched nucleobase uracil is commonly repaired through the base excision repair initiated by DNA uracil glycosylases. The data presented in this study strongly indicate that the nuclear uracil-N-glycosylase activity and nuclear protein content in human cell lines is highest in the S phase of the cell cycle and that its distribution kinetics partially reflect the DNA replication activity in replication foci. In this respect, the data demonstrate structural changes of the replication focus related to the uracil-N-glycosylase distribution several dozens of minutes before end of its replication.

Changes in hairiness of woven fabrics at the production and finishing stages.

Advances in the textile industry have led to a shift from using empirical experience to design fabrics to using computer-aided systems. Objective fabric properties related to appearance, feel, and comfort are predicted based on the physical models. The look and feel of fabrics are greatly influenced by their complex surface topology, which can be defined by two main properties: roughness and hairiness.

Altered olfactory responses in Fmr1 KO mice.

Fragile X syndrome (FXS) is a neurodevelopmental disorder oftentimes associated with abnormal social behaviors and altered sensory responsiveness. It is hypothesized that the inappropriate filtering of sensory stimuli, including olfaction, can lead to aberrant social behavior in FXS. However, previous studies investigating olfaction in animal models of FXS have shown inconsistent results.

Discovery of Orally Available Prodrugs of Itaconate and Derivatives.

Itaconate, an endogenous immunomodulator from the tricarboxylic acid (TCA) cycle, shows therapeutic effects in various disease models, but is highly polar with poor cellular permeability. We previously reported a novel, topical itaconate derivative, SCD-153, for the treatment of alopecia areata. Here, we present the discovery of orally available itaconate derivatives for systemic and skin disorders.

Development of a health equity tool in resuscitation sciences and application to current research in extracorporeal cardiopulmonary resuscitation for cardiac arrest.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used for adults with cardiac arrest (CA) refractory to Advanced Cardiovascular Life Support (ACLS). Concerns exist that adding ECPR could worsen health inequities, defined as differences in health outcomes that are unfair or unjust. Current guidelines do not explicitly address this issue.

Cross sections of the Ra(p,xn) reactions relevant for Ac production.

Limited availability constrains the implementation of Ac, the most promising α emitter for targeted therapy, in clinical practice. Proton activation of Ra is one of few realistic solutions to this problem. We have therefore measured cross sections of relevant Ra(p,xn) nuclear reactions in the energy range of 12.

Highly stable lithium metal anodes enabled by bimetallic metal-organic frameworks derivatives-modified carbon cloth.

Lithium (Li) metal anodes hold great promise for next-generation secondary batteries with high energy density. Unfortunately, several problems such as Li dendrite growth, low Coulombic efficiency and poor cycle life hinder the commercialization of Li metal anodes. Herein, we design a highly lithiophilic carbon cloth host modified with Sn-doped zinc oxide (ZnO) (ZnSn-CC) directly derived from a bimetallic ZnSn metal-organic framework (ZnSn-MOF), which boosts uniform Li plating/stripping during charge-discharge and effectively protects the Li metal anode.

SPR is a fast and straightforward method to estimate the binding constants of cyclic dinucleotides to their binding partners, such as STING or poxin.

The development of small molecule drugs that target protein binders is the central goal in medicinal chemistry. During the lead compound development process, hundreds or even thousands of compounds are synthesized, with the primary focus on their binding affinity to protein targets. Typically, IC or EC values are used to rank these compounds.

Dragonfly larvae rearing: experimental insights and best practices.

Understanding and optimizing rearing conditions for dragonfly larvae is crucial for ecological research and conservation efforts, yet optimal rearing conditions and general rearing practices are lacking. In this study, we investigated the effect of temperature, amount of oxygen in water, presence of (artificial) plants, and age of eggs on hatchability, survival, and development of dragonfly larvae using the model species Sympetrum striolatum. We conducted three independent experiments and assessed variability between egg clutches of individual females, as well as the occurrence of cannibalism among larvae.

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.

Synthesis of Xenes: physical and chemical methods.

Since the debut of silicene in the experimental stage more than a decade ago, the family of two-dimensional elementary layers beyond graphene, called Xenes or transgraphenes, has rapidly expanded to include elements from groups II to VI of the periodic table. This expansion has opened pathways for the engineering of elementary monolayers that are inherently different from their bulk counterparts in terms of fundamental physical properties. Common guidelines for synthesizing Xenes can be categorized into well-defined methodological approaches.

Acute Effects of Fast vs. Slow Bench Press Repetitions with Equal Time Under Tension on Velocity, sEMG Activity, and Applied Force in the Bench Press Throw.

It analyzed occult metastasis rates and explored relapse occurrences alongside potential predictors of lymph node metastasis.

Maturing conditions of bimetallic nanocomposites as a new factor influencing Au-Ag synergism and impact of Cu(II) and/or Fe(III) on luminescence.

Gold-silver synergism has been well documented in many scientific works dealing with luminescent nanostructures that are exploitable in biomedical and environmental application. Frequently, the ratio of Au : Ag in synthetic mixtures was varied to influence the extent of Au-Ag synergism of the resulting luminescent gold-silver nanoclusters (GSNCs). However, in our approach, a new step, maturing under differing conditions using the same Au : Ag ratio (5 : 1), has been investigated systematically for the very first time.
