Cyclometalated Au(III) complexes with alkynylphosphine oxide ligands: synthesis and photophysical properties.

A series of cyclometalated Au(III) complexes [Au(C^N^C)(C-L-P(O)Ph)] with C^N^C = 2,6-diphenylpyridine and alkynylphosphine oxide ligands (L = no linker, Au1; phenyl, Au2; biphenyl, Au3; naphthyl, Au4; anthracenyl, Au5) were synthesized and fully characterized by spectroscopic methods and single crystal XRD analysis. The complexes obtained exhibit triplet (Au1-Au3) and dual (Au4, Au5) emissions in solution, in the solid phase and in the PMMA film, whose characteristics depend on the linker's nature of the alkynylphosphine oxide ligand. The description of electronic transitions responsible for energy absorption and emission in Au(III) complexes was made on the basis of a detailed analysis of the results of DFT calculations and has shown to involve ILCT, LLCT and MLCT transitions of singlet and triplet nature.

Laser-Induced Olfactory Bulbectomy in Adult Zebrafish as a Novel Putative Model for Affective Syndrome: A Research Tribute to Brian Leonard.

Inducing multiple neurobehavioural and neurochemical deficits, olfactory bulbectomy (OBX) has been developed as a rodent model of depression with potential for antidepressant drug screening. However, the generality of this model in other vertebrate taxa remains poorly understood. A small freshwater teleost fish, the zebrafish (Danio rerio), is rapidly becoming a common model species in neuroscience research.

Complex species structure of (Digenea: Lecithasteridae), a fish parasite in the Arctic and Pacific Northwest.

Studying complexes of cryptic or pseudocryptic species opens new horizons for the understanding of speciation processes, an important yet vague issue for the digeneans. We investigated a hemiuroidean trematode across a wide geographic range including the northern European seas (White, Barents, and Pechora), East Siberian Sea, and the Pacific Northwest (Sea of Okhotsk and Sea of Japan). The goals were to explore the genetic diversity within through mitochondrial ( and genes) and ribosomal (ITS1, ITS2, 28S rDNA) marker sequences, to study morphometry of maritae, and to revise the life cycle data.

Deregulation mechanisms and therapeutic opportunities of p53-responsive microRNAs in diffuse large B-cell lymphoma.

Here, we have discussed the molecular mechanisms of p53-responsive microRNAs dysregulation in response to genotoxic stress in diffuse large B-cell lymphoma (DLBCL) patients. The role of micro ribonucleic acids (microRNAs) in p53-signaling cellular stress has been studied. MicroRNAs are the small non-coding RNAs, which regulate genes expression at post-transcriptional level.

Nexus of crude oil and clean energy stock indices: Evidence from time-vector-auto-regression in conjunction with conditional-autoregressive-value-at-risk.

The current study aims to elicit information regarding the tail risk transmission mechanism between crude oil (CO) and selected clean energy (CE) stock indices across time and during certain economic events. A Time-Varying Parameter Vector Auto-Regressive model (TVP-VAR) paired with the conditional autoregressive value-at-risk (CAViaR) approach was used to investigate data from January 1, 2015 to December 29, 2022. Overall, we show that an increased vulnerability to tail risk and deficits might be linked to dynamic spillover over examined markets.

Photocrosslinking of hyaluronic acid-based hydrogels through biotissue barriers.

Photocrosslinkable hydrogels based on hyaluronic acid are promising biomaterials high in demand in tissue engineering. Typically, hydrogels are photocured under the action of UV or blue light strongly absorbed by biotissues, which limits prototyping under living organism conditions. To overcome this limitation, we propose the derivatives of well-known photosensitizers, namely chlorin , chlorin and phthalocyanine, as those for radical polymerization in the transparency window of biotissues.

Drug carrier-assisted combined chemo- and radionuclide therapy for tumors of diverse origins: effects of therapeutic schemes on tumor responses.

Despite the promising results in cancer treatment, standard monotherapy remains insufficient for a wide range of oncological diseases. Combined therapy can significantly improve therapeutic outcomes compared to single-agent treatments. However, identifying the optimal treatment regimen for combined therapy can be a challenging task.

Overweight, obesity, and cardiovascular disease in heterozygous familial hypercholesterolaemia: the EAS FH Studies Collaboration registry.

Background And Aims: Overweight and obesity are modifiable risk factors for atherosclerotic cardiovascular disease (ASCVD) in the general population, but their prevalence in individuals with heterozygous familial hypercholesterolaemia (HeFH) and whether they confer additional risk of ASCVD independent of LDL cholesterol (LDL-C) remains unclear.

Methods: Cross-sectional analysis was conducted in 35 540 patients with HeFH across 50 countries, in the EAS FH Studies Collaboration registry. Prevalence of World Health Organization-defined body mass index categories was investigated in adults (n = 29 265) and children/adolescents (n = 6275); and their association with prevalent ASCVD.

The Puzzle of Food Inflation: Exploring the Asymmetric Nexus Between Economic Policy Uncertainty and Food Prices in the Expanded BRICS Countries.

Fluctuations in economic policy often create ripple effects that can significantly impact commodity prices, including those of essential food items, with potential consequences for food security. The five emerging nations outlined as BRICS (Brazil, Russia, India, China, and South Africa) have most recently extended by including four new members (Egypt, Ethiopia, Iran, and the UAE) on January 1, 2024. Additionally, Argentina and Saudi Arabia are anticipated to join the group soon.

The impact of combination of zofenopril and different diuretics on regression of myocardial reperfusion injury and oxidative status in spontaneously hypertensive rats.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.

Occupational exposure and sarcoidosis: a case-control study in three countries.

Background: Preceding studies of environmental and occupational risk factors of sarcoidosis yielded inconsistent findings.

Aims: We aimed to ascertain the occupational risk factors for sarcoidosis in a case-control study.

Methods: A total of 237 sarcoidosis patients with a histologically confirmed diagnosis were matched with 474 controls for sex and age (median 49, interquartile range 37; 60 years) recruited from the university hospitals and outpatient centres in Belarus, Kazakhstan and the Russian Federation.

Beyond what was said: Neural computations underlying pragmatic reasoning in referential communication.

The ability to infer a speaker's utterance within a particular context for the intended meaning is central to communication. Yet, little is known about the underlying neurocomputational mechanisms of pragmatic inference, let alone relevant differences among individuals. Here, using a reference game combined with model-based functional magnetic resonance imaging (fMRI), we showed that an individual-level pragmatic inference model was a better predictor of listeners' performance than a population-level model.

A thorny tale: The origin and diversification of Cirsium (Compositae).

Widely distributed plant genera offer insights into biogeographic processes and biodiversity. The Carduus-Cirsium group, with over 600 species in eight genera, is diverse across the Holarctic regions, especially in the Mediterranean Basin, Southwest Asia, Japan, and North America. Despite this diversity, evolutionary and biogeographic processes within the group, particularly for the genus Cirsium, remain underexplored.

The design of the spheroids-based in vitro tumor model determines its biomimetic properties.

Cancer, one of the world's deadliest diseases, is expected to claim an estimated 16 million lives by 2040. Three-dimensional (3D) models of cancer have become invaluable tools for the study of tumor biology and the development of new therapies. The tumor microenvironment (TME) is a determinant of tumor progression and has implications for clinical therapies.
