This study aimed to investigate the macroscopic, light microscopic (LM) and scanning electron microscopic (SEM) characteristics of the pecten oculi in common kestrels (Falco tinnunculus). A total of six eyeballs from three common kestrels were used as the study material. The examination revealed that the bulbus oculi was spherical in shape and its diameter exceeded the axial-global length.

Novel smart materials with high curie temperatures: EuDyGeO, EuLaGeO and EuHoGeO.

Appl Radiat Isot

December 2024

Department of Metallurgy and Materials Engineering, Faculty of Engineering and Natural Sciences, Konya Technical University, Konya, Turkey.

The EuDyGeO, EuLaGeO and EuHoGeO powder were obtained through a solid-state reaction method via multistep firing of stoichiometric ratios of EuO, GeO, DyO, LaO and HoO in open atmosphere at temperatures from 800 to 1150 °C. The thermal behaviour, phase formation, SEM/EDX analysis, photoluminescence properties, Curie tempereture, dielectric and piezoelectric properties of the samples were investigated by TG/DTA, XRD, SEM, PL, TG/DTA, LCR-meter and d-meter, respectively. The germenates having triclinic crystal system have D→F, D→F, D→F, D→F transitions of Eu ions.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Article Synopsis
  • The study aimed to determine effective cutoff scores for the Psoriatic Arthritis Impact of Disease questionnaire (PsAID12) based on disease activity measures in patients with PsA.
  • Using data from the ReFlaP study, researchers analyzed scores to define disease states such as remission and varying impact levels, employing statistical methods to establish these cutoffs.
  • Results indicated that the PsAID12 score had high diagnostic performance against established benchmarks, but further validation and expert consensus are needed to confirm the proposed cutoffs for clinical use.

Bone marrow adipose tissue (BMAT) has garnered significant attention due to its critical roles in leukemia pathogenesis, cancer metastasis, and bone marrow failure. BMAT is a metabolically active, distinct tissue that differs from other fat depots. Marrow adipocytes, closely interacting with hematopoietic stem/progenitor cells and osteoblasts, play a pivotal role in regulating their functions.

Introduction: Vaccine platforms such as viral vectors and mRNA can accelerate vaccine development in response to newly emerging pathogens, as demonstrated during the COVID-19 pandemic. However, the differential effects of platform and antigen insert on vaccine immunogenicity remain incompletely understood. Innate immune responses induced by viral vector vaccines are suggested to have an adjuvant effect for subsequent adaptive immunity.

Acenaphthylene-fused heteroarenes with a variety of five- and six-membered heterocycles such as thiophene, furan, benzofuran, pyrazole, pyridine and pyrimidine were synthesized via an efficient Pd-catalyzed reaction cascade in good to high yields (45-90%). This cascade involves an initial Suzuki-Miyaura cross-coupling reaction between 1,8-dihalonaphthalenes and heteroarylboronic acids or esters, followed by an intramolecular C-H arylation under the same conditions to yield the final heterocyclic fluoranthene analogues. The method was further employed to access polyoxygenated benzo[]fluoranthenes, which are all structurally relevant to benzo[]fluoranthene-based fungal natural products.

S-Sulfocysteine (SSC) is a metabolite derived from the metabolism of sulfur-containing amino acids. It has been implicated in neurotoxicity observed in children with sulfite oxidase deficiency. The aim of our study was to confirm the neurotoxic effects of SSC using a mouse hippocampal cell line (HT-22) and to investigate the role of apoptosis in these effects, especially in terms of caspase-3 activation and genotoxicity.

Iron in the migraine brain.

Histol Histopathol

December 2024

Hacettepe University, Institute of Neurological Sciences and Psychiatry, Ankara, Türkiye.

Iron, a vital element for numerous peripheral and central nervous system functions, is a key player in DNA synthesis, gene expression, myelination, neurotransmission, and mitochondrial electron transport. Iron has utmost importance in various neurological functions, including neurotransmitter synthesis and brain cell metabolism. Migraine is a neurogliovascular disorder in which neuroinflammation plays a crucial role.

Hajdu-Cheney syndrome (HCS), caused by a heterozygous gain of function variant of the NOTCH2 gene, is a rare skeletal dysplasia. Although the main presentation is acro-osteolysis, osteoporosis, and facial dysmorphism, having a wide range of clinical manifestations creates diagnostic difficulties. Here, a 15-year-old male patient with HCS who had no complaints until this age except for two short bone fractures and one vertebral collapse fracture due to a fall was reported.

Recent advances in next generation sequencing (NGS) have positioned whole exome sequencing (WES) as an efficient first-tier method in genetic diagnosis. However, despite the diagnostic yield of 35%-50% in intellectual disability (ID) many patients still remain undiagnosed due to inherent limitations and bioinformatic short-comings. In this study, we reanalyzed WES data from 159 Iranian families showing recessively inherited ID.
