Photoinduced Dynamics of [N(C3H7)4]2Cu4Br6 Thin Films with Dual Self-Trapped Exciton Emission and Negative Thermal Quenching.

Organic-inorganic halocuprates(I) form a promising class of light-emitting materials with high photoluminescence (PL) quantum yield. However, the understanding of their emission properties and the PL mechanism is still limited. Here, we investigate thin films of bis(tetrapropylammonium) hexa-µ-bromo-tetrahedro-tetracuprate(I), [N(C3H7)4]2[Cu4Br6], which has a zero-dimensional (0D) molecular salt structure containing [Cu4Br6]2- ions.

Impact of Lewis Acids on the Reactivity of a High-Valent Cu(III) Complex.

Redox-inactive metal ions functioning as Lewis acids (LA) play a significant role in modulating the redox reactivity of metal-oxygen intermediates such as metal-oxo, metal-superoxo, and metal-peroxo species. In photosystem II (PS-II), the redox-inactive metal ion Ca is critical for O activation, although its precise function remains unclear. Inspired by nature's use of redox-inactive metal ions, this study aims to characterize complexes of high-valent Cu(III) bound Lewis acids, (where M = Zn, Eu, Yb, and Sc), through various spectroscopic techniques, including UV-vis and resonance Raman spectroscopic analyses.

Linking epidemiology and genomics of maternal smoking during pregnancy in utero and in ageing: a population-based study using human foetuses and the UK Biobank cohort.

Background: Maternal smoking and foetal exposure to nicotine and other harmful chemicals in utero remains a serious public health issue with little knowledge about the underlying genetics and consequences of maternal smoking in ageing individuals. Here, we investigated the epidemiology and genomic architecture of maternal smoking in a middle-aged population and compare the results to effects observed in the developing foetus.

Methods: In the current project, we included 351,562 participants from the UK Biobank (UKB) and estimated exposure to maternal smoking status during pregnancy through self-reporting from the UKB participants about the mother's smoking status around their birth.

Sulfur traits in the plant microbiome: implications for sustainable agriculture.

Owing to its biochemical flexibility, sulfur (S) is uniquely poised to fulfill versatile roles in plant-microbe interactions - impacting their metabolism with significant consequences for plant health and the global S cycle. We present evidence that the diversity of S-metabolic genes in plant-associated microbiomes (phytobiomes) is underappreciated, and plant niches are hotspots of bacterial S-metabolism with implications for S emissions. Building upon emerging findings, we posit that coordination of S-metabolism between plants and phytobiomes is a common mechanism for plant-microbe homeostasis and agriculturally beneficial microbial services.

Hidden aging: the secret role of root senescence.

Root age-dependent processes have remained poorly understood. Here, we define root age-related terms in their eco-/physiological context, provide a synthesis of read-outs and traits characterizing root senescence in different root types, and follow their modulation in the light of metabolic, hormonal, and genetic control. Evidence for an endogenously regulated senescence program in roots includes changes in root anatomy, metabolism, and color, decrease in root activity, increasing levels of stress-related hormones, and increasing expression of certain transcription factors (TFs) or genes involved in oxidative stress defense.

Assessing the marginal seal of bioactive restorative materials in class II cavities with a bacterial penetration model.

Objectives: The aim of this study was to examine the marginal seal of novel bioactive restorative materials and the material-related properties associated with bacterial microleakage.

Bacterial microleakage was visualized with a modified gram staining protocol and bacterial penetration depths were microscopically determined after sectioning the teeth.

Lewis-Base-Catalyzed Asymmetric Allylation of Isatins with Allyltrichlorosilane.

Herein we report the enantioselective synthesis of 3-allyl-3-hydroxyoxindoles, a core scaffold in a wide range of bioactive molecules, using a Lewis-base catalyst and readily abundant and inexpensive allyltrichlorosilane. This transition-metal-free protocol employs relatively low catalyst loadings of a privileged bispyrrolidine-type scaffold to achieve high yields and enantioselectivities (up to 98% yield and 98:2 er). The total syntheses of the natural products (-)-flustraminol B and (-)-chimonamidine were also successfully carried out using our newly developed method as a key step, highlighting the potential of this method for the efficient and precise synthesis of complex natural products.

Buffer Specificity of Ionizable Lipid Nanoparticle Transfection Efficiency and Bulk Phase Transition.

Lipid nanoparticles (LNPs) are efficient and safe carriers for mRNA vaccines based on advanced ionizable lipids. It is understood that the pH-dependent structural transition of the mesoscopic LNP core phase plays a key role in mRNA transfer. However, buffer-specific variations in transfection efficiency remain obscure.

Sleep Health and White Matter Integrity in the UK Biobank.

Many people experience impaired sleep health, yet knowledge about its neurobiological correlates is limited. As previous studies have found associations between white matter integrity and several sleep traits, white matter integrity could be causally implicated in poor sleep health. However, these studies were often limited by small sample sizes.

Curvisetone─A Male-Specific Tricyclic -Diterpenoid from the Springtail .

The structure determination and occurrence of curvisetone (), a tricyclic nor-diterpenoid from the tiny Collembola , is reported. Utilizing NMR analysis and mass spectrometry, we identified curvisetone's unique carbon skeleton and its occurrence in various sex and life stages. Curvisetone, carrying an unprecedented carbon tricyclic ring system, is an example of the distinct terpene usage of Collembola, which differentiates them from other arthropods.

Neurodevelopmental and psychiatric conditions in 600 Swedish children with the avoidant/restrictive food intake disorder phenotype.

Background: Avoidant restrictive food intake disorder (ARFID) is a feeding and eating disorder characterized by extremely restricted dietary variety and/or quantity resulting in serious consequences for physical health and psychosocial functioning. ARFID often co-occurs with neurodevelopmental conditions (NDCs) and psychiatric conditions, but previous data are mostly limited to small clinical samples examining a narrow range of conditions. Here, we examined NDCs and psychiatric conditions in a large, population-based group of children with ARFID.

Best Practices for Imaging of Transcatheter Valve Failure: An Update From the Heart Valve Collaboratory.

This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.

Handedness.

This chapter offers an overview of the literature on human handedness and its assessment in clinical neurologic practice and research. There are two major forms of handedness: hand preference, which describes a subjective preference to use one hand over the other for skilled motor activities like writing, and hand skill, which describes objectively measured mother skill. This chapter gives an overview of widely used questionnaires and tests to assess hand preference and hand skill, as well as suggestions on how to determine handedness categories such as left-handed, right-handed, and mixed-handed based on the results of these questionnaires and tests.

Functional and structural brain asymmetries in sign language processing.

The capacity for language constitutes a cornerstone of human cognition and distinguishes our species from other animals. Research in the cognitive sciences has demonstrated that this capacity is not bound to speech but can also be externalized in the form of sign language. Sign languages are the naturally occurring languages of the deaf and rely on movements and configurations of hands, arms, face, and torso in space.

Functional and structural brain asymmetries in language processing.

The lateralization of language to the left hemisphere of the human brain constitutes one of the classic examples of asymmetry in biology. At the same time, it is also commonly understood that damage to the left hemisphere does not lead to a complete loss of all linguistic abilities. These seemingly contradictory findings indicate that neither our cognitive capacity for language nor its neural substrates are monolithic.

Split-brain patients: A clinical vs experimental perspective.

For more than 80 years, the clinical perspective on the behavioral outcome of split-brain surgery suggested that it "may be carried out without any untoward effect on the patient," despite some initial and transient disconnection effects. The last 60 years of experimental studies, however, have shown quite the opposite. Using lateralized testing procedures, split-brain patients have demonstrated profound disconnection effects that can last a lifetime.

Large language models for surgical informed consent: an ethical perspective on simulated empathy.

Informed consent in surgical settings requires not only the accurate communication of medical information but also the establishment of trust through empathic engagement. The use of large language models (LLMs) offers a novel opportunity to enhance the informed consent process by combining advanced information retrieval capabilities with simulated emotional responsiveness. However, the ethical implications of simulated empathy raise concerns about patient autonomy, trust and transparency.
