Structure-Activity Relationship Study of Splicing Modulators on Hsh155/SF3B1 through Chemical Synthesis and Yeast Genetics.

Meayamycins are synthetic analogs of the natural product FR901464 and exhibit potent anticancer activity against human cancers. They bind SF3B1 and PHF5A, components of the human spliceosome, and they alter pre-mRNA splicing. Detailed analysis of the active site led us to investigate a narrow pocket within the binding site that surrounds the α,β-unsaturated amide portion of meayamycin.

Child Abuse and Neglect and Obsessive-Compulsive Personality Traits: Effects of Attachment, Intolerance of Uncertainty, and Metacognition.

Child Abuse and Neglect (CAN) is extensively implicated as a risk factor preceding the development of Obsessive-Compulsive Personality Traits (OCPT). Nevertheless, the majority of individuals with a history of CAN do not go on to develop OCPT. To date, little research has investigated potential model networks that may help contribute to explaining why CAN sometimes leads to OCPT and not at other times.

Switchable Fluorescence of a Mechanical Stimulus-Responsive Au-P-S Complex.

Elucidating the Mechanism of Electrooxidative Allene Dioxygenation: Dual Role of Tetramethylpiperidine -Oxyl (TEMPO).

The cumulated π system of a nonsymmetric allene contains three distinct unsaturated carbons that imbue it with unique reactivity toward radicals as compared to its alkene and alkyne counterparts. Despite the synthetic potential of these versatile building blocks, electrochemical transformations of allenes have been historically underexplored. Myriad strategies for easy access to allenes, coupled with the resurgence of interest in sustainable oxidative transformations of hydrocarbons, prompted our efforts to conduct an in-depth investigation of a rare example of an electrochemical TEMPO-mediated allene dioxygenation.

Time-series data from a hybrid finite element Large Eddy Simulation of flow over a backward-facing step.

In previous work, a Large Eddy Simulation turbulence (LES) algorithm was developed for finite element-based computational fluid dynamics, using a hybrid continuous-discontinuous Galerkin scheme. The test case for this was a backward-facing step, which is a well-known example with published experimental results for validation. The results of this simulation were used to produce temporal statistics, such as averaged velocity and Reynolds stress profiles, and time-series data.

Chimeric aggregative multicellularity in absence of kin discrimination.

Aggregative multicellularity is a cooperative strategy employed by some microorganisms. Unlike clonal expansion within protected environments during multicellular eukaryotic development, an aggregation strategy introduces the potential for genetic conflicts and exploitation by cheaters, threatening the stability of the social system. , a soil-dwelling bacterium, employs aggregative multicellularity to form multicellular fruiting bodies that produce spores in response to starvation.

BAMITA: Bayesian multiple imputation for tensor arrays.

Data increasingly take the form of a multi-way array, or tensor, in several biomedical domains. Such tensors are often incompletely observed. For example, we are motivated by longitudinal microbiome studies in which several timepoints are missing for several subjects.

The right to health for socioeconomically disadvantaged TB patients in South Korea: An AAAQ framework analysis.

Tuberculosis, a disease of poverty, continues to disproportionately affect socioeconomically disadvantaged populations worldwide. This is particularly concerning given the recent resurgence of TB following the COVID-19 pandemic. In South Korea, despite substantial socioeconomic development, TB remains a prominent problem, ranking as the leading infectious killer in the country.

PNKP safeguards stalled replication forks from nuclease-dependent degradation during replication stress.

Uncontrolled degradation and collapse of stalled replication forks (RFs) are primary sources of genomic instability, yet the molecular mechanisms for protecting forks from degradation/collapse remain to be fully elaborated. Here, we show that polynucleotide kinase-phosphatase (PNKP) localizes at stalled forks and protects stalled forks from excessive degradation. The loss of PNKP results in nucleolytic degradation of nascent DNA at stalled RFs.

Photoredox-Catalyzed Decarboxylation of Oxetane-2-Carboxylic Acids and Unique Mechanistic Insights.

Oxetanes are valuable motifs in medicinal chemistry applications, with demonstrated potential to serve as bioisosteres for an array of functional groups. Through the visible-light-mediated photoredox hydrodecarboxylation of 2-aryl oxetane 2-carboxylic acids this work enables access to the products of a [2+2]-photocycloaddition between alkenes and aryl aldehydes without the challenges associated with a traditional UV-light-mediated Paternò-Büchi reaction. Investigation into the hydrodecarboxylation mechanism reveals substrate-dependent modes of initiation under the conditions reported herein.

Navigating challenges and cultivating connections: Faculty experiences teaching RN-BSN students.

Background: Success in completing an RN to BSN program largely depends on program quality, flexibility, and accessibility, as well as faculty ability to help students navigate several complex factors. Research specific to the RN-BSN student experience suggests that faculty teaching in RN-BSN programs must be respectful of diverse learners' needs, mindful to avoid bias and reduce stigma, and capable in creating equitable learning spaces. Faculty must also make content relevant to support immediate use by students in the workplace.

Does Annulus Fibrosus Lamellar Adhesion Testing Require Preconditioning?

The interlamellar matrix (ILM), located between the annular layers of the intervertebral disc (IVD), is an adhesive component which acts to resist delamination. Investigating the mechanical properties of the ILM can provide us with valuable information regarding risk of disc injury; however given its viscoelastic nature, it may be necessary to conduct preconditioning on tissue samples before measuring these ILM properties. Therefore, the aim of this study was to optimize mechanical testing protocols of the ILM by examining the effect of preconditioning on stiffness and strength of this adhesive matrix.

Silicon-based Linkers for Tunable Acid-Sensitive Drug Release from Polymeric Nanoparticles.

Active Pharmaceutical Ingredients (APIs) may benefit from a carrier to improve their pharmacokinetic and pharmacodynamic properties. Core-crosslinked polymeric micelles (CCPMs) are carriers for hydrophobic small molecule APIs. In CCPMs, APIs are generally covalently coupled to the core of the micelles by use of a linker, which can be tailored to adjust the release rate of the API.

Heat strain in road construction workers during the summer in New Mexico: a preliminary study.

Unlabelled: In the summer season, road construction workers perform physically demanding tasks outdoors, placing them at greater risk for exertional heat illness conditions. Assessing core temperature (Tcore) is critical as it serves as a key indicator of heat strain and helps to estimate the risk of heat-related illness. Despite the increased risk of hyperthermia, previous research has not assessed Tcore in road construction workers in the United States during summer work.

Constrained β-Hairpins Targeting the EphA4 Ligand Binding Domain.

The activity of the receptor tyrosine kinase EphA4 has been implicated in several pathologies including oncology (gastric and pancreatic cancers) and neurodegenerative diseases (amyotrophic lateral sclerosis and Alzheimer's disease). However, advances in validating EphA4 as a possible drug target have been limited by the lack of suitable pharmacological inhibitors. Recently, we reported on the design of potent EphA4 agonistic agents targeting its ligand binding domain (LBD).

We enhance single-ion magnet (SIM) magnetisation reversal barriers by engineering the second coordination sphere, substituting conventional small monoanions with a bulky polyoxometalate (POM) trianion. Importantly, our approach serves as a model for creating new high-performance multifunctional hybrid materials.

Graph theory approaches for molecular dynamics simulations.

Graph theory, a branch of mathematics that focuses on the study of graphs (networks of nodes and edges), provides a robust framework for analysing the structural and functional properties of biomolecules. By leveraging molecular dynamics (MD) simulations, atoms or groups of atoms can be represented as nodes, while their dynamic interactions are depicted as edges. This network-based approach facilitates the characterization of properties such as connectivity, centrality, and modularity, which are essential for understanding the behaviour of molecular systems.

High-Temperature Polymorphism and Band-Gap Evolution in BaZrS.

Barium zirconium trisulfide (BZS) is a three-dimensional (3D) perovskite with optoelectronic properties suitable for photovoltaic (PV) and light-emitting diode (LED) applications that is conventionally reported in the orthorhombic (62) symmetry. Synchrotron X-ray diffraction, thermal analysis, and Raman and absorption spectroscopy revealed three high-temperature polymorphs that appear when BZS is heated in air prior to complete oxidation (BaZrS + 5O → BaSO + ZrO + 2SO↑) at 700 °C with the approximate stability ranges: BaZrS IV (62)T < 400 °CBaZrS III (63)400 °C ≤ T ≤ 500 °CBaZrS II14/ (140)500 °C ≤ T ≤ 700 °CDifferential scanning calorimetry (DSC) revealed exothermic features accompanying the IV → III and III → II phase changes. Furthermore, the direct band gap varied inversely with temperature with distinct energies for each polymorph (1.
