Luminescent Properties of Pr-Doped LiBaF Crystallites.

Research is ongoing to develop new phosphors capable of emitting light across a broad spectrum, ranging from the ultraviolet (UV) to the infrared region, with potential applications in diverse fields. Using the method of solid-state reactions, a series of LiBaF:Pr phosphors were obtained, and their luminescent properties in the UV-visible range were studied. The photon cascade emission (PCE) phenomenon has been observed under excitation of the 4f5d bands of Pr.

Uncovering the genetic basis of antiviral polyketide limocrocin biosynthesis through heterologous expression.

Background: Streptomyces roseochromogenes NRRL 3504 produces clorobiocin, an aminocoumarin antibiotic that inhibits DNA replication. No other natural products have been isolated from this bacterium so far, despite the presence of a rich repertoire of specialized metabolite biosynthesis gene clusters (smBGCs) within its genome. Heterologous expression of smBGCs in suitable chassis speeds up the discovery of the natural products hidden behind these sets of genes.

Dietary supplementation and the role of phytochemicals against the Alzheimer's disease: Focus on polyphenolic compounds.

Alzheimer's disease is a complicated, multifaceted, neurodegenerative illness that places an increasing strain on healthcare systems. Due to increasing malfunction and death of nerve cells, the person suffering from Alzheimer's disease (AD) slowly and steadily loses their memories, cognitive functions and even their personality. Although medications may temporarily enhance memory, there are currently no permanent therapies that can halt or cure this irreversible neurodegenerative process.

Assessing the benzimidazole resistance in equine strongyles by in vitro methods.

The study aimed to conduct a survey on the occurrence of benzimidazole (BZ) resistance in strongyles by in vitro egg hatch test (EHT) and larval development test (LDT) and to identify the effective indicators of early resistance detection on horse farms with associated risk factors analysis appraisal. In total, 203 horses from 8 farms underwent the fecal sampling of which 77 horses were selected for in vitro testing. Simultaneously, 18 horses were chosen to analyse the results of in vitro tests compared to the in vivo fecal egg count reduction test (FECRT).

Absorption spectra of PS in the ultraviolet and infrared region.

The line list is essential for accurately modeling various astrophysical phenomena, such as stellar photospheres and atmospheres of extrasolar planets. This paper introduces a new line database for the PS molecule spanning from the ultraviolet to the infrared regions, covering wavenumbers up to 45000 cm and containing over ten million transitions between 150,458 states with total angular momentum J < 160. Accurate line intensities for rotational, vibrational and electronic transitions are generated by using the general purpose variational code DUO.

Progress and Challenges in Integrating Nutritional Care into Oncology Practice: Results from a National Survey on Behalf of the NutriOnc Research Group.

Introduction: Nutritional care is a cornerstone of cancer treatment, with the potential to significantly improve patient outcomes by addressing malnutrition and enhancing recovery. Despite growing awareness, the integration of evidence-based nutritional strategies into oncology remains inconsistent. Following a 2020 survey that highlighted critical gaps, the NutriOnc Research Group launched targeted initiatives to raise awareness and improve practices.

Crystal Plasticity Simulation of Cyclic Behaviors of AZ31B Magnesium Alloys via a Modified Dislocation-Twinning-Detwinning Model.

In this study, a probabilistic model within the dislotwin constitutive framework of DAMASK (the Düsseldorf Advanced Material Simulation Kit) was established to describe the cyclic loading behaviors of AZ31B magnesium alloys. Considering the detwinning procedure within the twinned region, this newly developed dislocation-twinning-detwinning model was employed to accurately simulate stress-strain behaviors of AZ31B magnesium alloys throughout tension-compression-tension (T-C-T) cycle loading. The investigations revealed that the reduction in yield stress during the reverse loading process was attributed to the active operation of twinning and detwinning modes.

Resonant and Non-Resonant Impurity States Related to GaAs/AlGaAs Quantum Well Sub-Bands.

The energy positions and wave function shapes of the ground and excited states of impurities, including resonance states, are studied using the expansion of the impurity wave function in basis functions. The structures under study are rectangular GaAs/AlGaAs quantum wells with four different widths. In all cases, the impurity binding energy (relative to the corresponding sub-band) has a maximum at or near the center of the quantum well, decreases as the heterointerface is approached, and apparently has a limit of 0 if the impurity moves deeper into the barrier.

Social Relationships of Captive Bachelor Przewalski's Horses and Their Effect on Daily Activity and Space Use.

Understanding social relationships in at-risk species held in captivity is vital for their welfare and potential reintroduction. In social species like the Przewalski's horse (), daily time allocation and space use may be influenced by social structure and, in turn, reflect welfare. Here, we identify social relationships, time budgets, and spatial distribution of a group of nine older (aged 6-21 years) male Przewalski's horses living in a non-breeding (bachelor) group.

Sr and Cs distribution in Chornobyl forests: 30 years after the nuclear accident.

The primary aim of this study was to quantify patterns in the distribution of Sr and Cs activity in pine (Pinus sylvestris L.: 18 sites) and birch (Betula pendula Roth.: 2 sites) forests within the Chornobyl exclusion zone, 30 years after the Chornobyl nuclear power plant (NPP) accident (1986).

Across the firewall: Foreign media's role in shaping Chinese social media narratives on the Russo-Ukrainian War.

There is a widespread perception that China's digital censorship distances its people from the global internet, and the Chinese Communist Party, through state-controlled media, is the main gatekeeper of information about foreign affairs. Our analysis of narratives about the Russo-Ukrainian War circulating on the Chinese social media platform Weibo challenges this view. Comparing narratives on Weibo with 8.

Multiomics dissection of human RAG deficiency reveals distinctive patterns of immune dysregulation but a common inflammatory signature.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Psychogenetic Features of Heredity and Pathology.

The purpose of this study is to provide an in-depth examination of the complex aspects of hereditary and pathological conditions arising based on psychogenetic factors, in particular, the disclosure of elements that determine the causes of their appearance. The following methods were used in the study: analytical, typological approaches, and generalization. It was found that genetic inheritance plays a significant role in the occurrence of autism spectrum disorders, bipolar disorder, schizophrenia, and other pathologies.
