Evaluation of optical coherence tomography and optical coherence tomography angiography findings of fibromyalgia.

Background: To execute comprehensive study about optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) findings in fibromyalgia (FM) to elaborate macula, optic disk changes.

Methods: A total of 84 participants comprising 44 FM patients and 40 healthy controls were included. Macular full thickness, retinal nerve fiber layer (RNFL), ganglion cell layer (GCL)+, GCL++, superficial vessel density (SVD), deep vessel density (DVD), foveal avascular zone (FAZ), circumpapillary vessel density (cpVD), RNFL measurements were evaluated using OCT/OCTA.

Eco-friendly synthesis of Carbon Quantum Dots (CQDs) from hazelnut husk for sensitive Aflatoxin B1 (AFB1) detection.

In this study, green fluorescent carbon quantum dots (CQDs) with remarkable stability, water solubility, and biocompatibility were synthesized from hazelnut husk (HH) waste material using a novel approach by the pyrolysis method. The optical properties of the synthesized HH-CQDs were characterized by UV-Vis and fluorescence spectroscopy (PL), while their structural properties were characterized using various techniques, including transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). TEM images revealed that HH-CQDs had a spherical shape with diameters ranging from 2 to 10 nm.

New Styryl 1,3,4-Oxadiazol-Based Fluorometric "Turn on" pH Sensor.

A new 1,3,4-oxadiazole derivative (MeO-SODA) was synthesized, fully characterized by means of IR, NMR and HRMS data and and additionally, its ability to detect extremely acidic pH values ​​was examined. Firstly, the characteristic behavior of MeO-SODA was examined in ten different solvents, revealing that it underwent non-radiative transitions as the hydrogen bonding capacity of solvent increased. Secondly, the absorption and fluorescence measurements for MeO-SODA were conducted across various pH levels (pH 2, 4, 6, 7, 9, 10, 12), with fluorescence emission observed exclusively at pH 2.

Green synthesis of carbon dot structures from and Schottky diode fabrication.

In this study, we aimed to synthesize new carbon dot structures (CDs) in a single step by using the plant for the first time and to contribute to the studies in the field of diode fabrication by using the new CDs. The CDs were obtained by hydrothermal synthesis, which is commonly used in the literature. TEM and zeta potential measurements were used to determine morphology and sizes of the CDs, and XRD, XPS, and FTIR and micro-Raman spectroscopy were used for structural characterization.

Incidence and predictors of permanent pacemaker implantation after transcatheter aortic valve implantation with a balloon-expandable biosprosthesis in patients with bicuspid aortic valves.

Introduction: There are few data on permanent pacemaker implantation (PPMI) in patients who have undergone transcatheter aortic valve implantation (TAVI) for bicuspid aortic valve (BAV) stenosis.

Aim: The purpose of this study was to evaluate the predictors and incidence of PPMI in bicuspid patients using a balloon-expandable (BE) TAVI device.

Material And Methods: A total of 62 patients with bicuspid morphology who had undergone successful TAVI using a BE device without previous PPMI were included (retrospectively).
