The objective was to investigate the effect of 4-hydroxybenzoic acid (4-HBA) and 4-hydroxy-3-methoxybenzoic acid (Vanillic acid, VA) on p-glycoprotein (P-gp) activity in multidrug-resistant K562/Dox cancer cells. The cytotoxic and co-treatment with pirarubicin (Pira) were analyzed using a resazurin assay. A noninvasive functional spectrofluorometric technique was used to determine the kinetics of Pira uptake in living multidrug-resistant K562/Dox cancer cells. The three biological endpoints for determination of cellular energetic state included the activity of mitochondria, mitochondrial membrane potential (ΔΨm), and ATP levels. The results revealed that 4-HBA (10 mM) and VA (5 and 10 mM) statistically decreased cell viability in K562 and multidrug-resistant K562/Dox cancer cells. In ways consistent with that result, 4-HBA and VA (0.01, 0.1, 1, and 10 mM) could statistically decrease the IC₅₀ of Pira in K562 and multidrug-resistant K562/Dox cancer cells at 48 and 72 h. The overall intracellular Pira concentration increased in 4-HBA- and VA-treated multidrug-resistant K562/Dox cancer cells when compared to control. The ratio of k_aⁱ/k_a⁰ in 4-HBA- and VA-treated multidrug-resistant K562/Dox cancer cells was significantly decreased when 4-HBA and VA concentration increased. The activity of mitochondria, ΔΨm, and ATP levels significantly reduced in multidrug-resistant K562/Dox cancer cells incubated with 0.01, 0.1, 1, and 10 mM 4-HBA and VA at all harvest time points. In conclusion, 4-HBA and VA were able to bring about cell death in multidrug-resistant K562/Dox cancer cell at high concentrations. The 4-HBA and VA could modify P-gp function via an impaired cellular energetic state, resulting in increased in intracellular drug concentration in multidrug-resistant K562/Dox cancer cells. © 2022 The Authors

The present work focuses on synthesizing Sr2ZnMoO6:Sm2O3 phosphor-mixed TeO2: ZnO: B2O3 glass by microwave synthesis technique at different times (16, 18, 20, 22, 24 min). These samples, after synthesizing they were characterized through XRD, FTIR, density, molar volume, refractive index, absorption spectra, luminescence properties, and lifetime *** study of crystalline nature was studied using XRD spectra of Sr2ZnMoO6. Absorption spectra were evaluated in the wavelength region between 400 and 1800 nm and found seven peaks, which corresponded with the energy transitions of Sm3+ion from the ground level of 6H5/2 → 6F11/2, 9/2, 7/2, 5/2, 3/2, 6H15/2, and 6F1/2 at 944, 1083, 1238, 1383, 1485 and 1543 nm respectively. The photoluminescence in the wavelength region of 500–750 nm using the excitation wavelength at 403 nm. The emission intensity of the samples increased with sintering time until 20 min after which it decreased. The highest peak was observed at 597 nm, corresponding to 4G5/2 → 6H7/2 (orange) transitions of Sm3+ ion. The luminescence lifetime from the 4G5/2 to 6H7/2 level increased with increasing sintering time until 20 min, which had a lifetime of 0.431–0.711 ms when monitored at λex = 403 nm. The results obtained in photoluminescence properties showed that the samples could be potential candidates for orange light-emitting diodes for solid-state lighting applications. © 2023 Elsevier GmbH

CeF3 doped gallium lutetium aluminium yttrium borate glasses were investigated for photonics applications in this work. Their physical, structural, optical and luminescence properties were studied by the effect of CeF3 concentration. Glass density and refractive index raised with increasing CeF3 amount. The FTIR spectra and XRD pattern demonstrated that the glass network consisted of trigonal BO3 and tetragonal BO4 borate groups cooperating with metal oxides in amorphous nature, while CeF3 dopant acted as a glass modifier. Glass strongly absorbed the photons in ultraviolet region by transition of host component, superposed with the 4 f→5d transition of Ce3+ dopant. Under UV excitation, glass doped with 0.05 mol%-CeF3 performed the highest emission intensity at 391 nm by 5d→4 f transition. Due to the strong blue emission, half photons conversion ability and short decay time around 21 ns, this developed glass owns a potential for the blue light sources / medium and the ultraviolet to visible light converter. © 2023 Elsevier GmbH

In this study, GdBO3 phosphors doped with varying concentrations of Sm3+ were synthesized using the solid-state reaction technique at a temperature of 900 °C for 18 h. The SmXGd1−XBO3 phosphors were investigated on different chemical compositions, ranging from x = 0.000–0.150. The crystal structure exhibited a hexagonal GdBO3 phase. Excitation by a 403 nm wavelength resulted in the observed maximum emission peak at 604 nm from all SmXGd1−XBO3 phosphors. The highest emission intensity was achieved at x = 0.075. The emitted light was determined to be orange based on the calculated stimulated CIE chromaticity coordinates, and the correlated color temperature (CCT) was found to be 1634 K. Furthermore, the radioluminescence performance of the phosphors was measured to be 14.3 % and 113.9 % compared to that of commercial BGO and red luminescence powder, respectively. © 2023 Elsevier GmbH

The Dy3+-activated aluminum sodium calcium borate glass with white light emission might have been created through the melt-quenching process. This research explores the optical and luminescence characteristics of borate glasses. Dy3+-activated glasses exhibit absorption in the visible (VIS) and near-infrared spectrums. The absorption starts from the 6H15/2 ground state to the higher state concerning optical characteristics. The emission spectra of dysprosium-doped glasses' photoluminescence show greater intensity at 483 nm (blue light) and 575 nm (yellow light), which are critical wavelengths for white light-generating materials. The luminescence intensity of Dy3+ ions increased up to a 0.50 mol% concentration, while the decay time decreased with an increasing dysprosium ion concentration. The emission spectra were used to estimate the CIE 1931 chromaticity and corresponding color temperature, revealing a shift towards the cold white light location at that temperature. The stimulated emission cross-section is calculated via the Judd-Ofelt theory. All characteristic outcomes suggest that the existing dysprosium-enabled glasses are excellent materials for generating cool white light in W-LED applications. © 2024 Elsevier GmbH

Eu2O3-doped K2O-Gd2O3-P2O5 glasses were fabricated using the melt-quenching technique. The result indicates that the glasses' density and refractive index increase while the molar volume decreases from 0.05 to 0.5 mol% and then increases from 0.5 to 2 mol% with increased Eu2O3 concentration. The absorption spectra in the UV-Vis and NIR regions exhibit an energy transition from a ground state to possible excited states for 7F0 → 5K5, 7F0 → 3P0, 7F1 → 5G2, 7F0 → 5L6, 7F1 → 5D3, 7F0 → 5D2, 7F1 → 5D1 and 7F0 → 7F6, and 7F1 → 7F6. The luminescence characteristics were examined by photoluminescence (PL) and radioluminescence (RL). Both PL and RL confirmed that the optimum value at 2 mol% of Eu2O3 concentration. Similarly, the luminescence efficiency of 2 mol% Eu2O3 concentration compared with the BGO crystal equals 16.77%. As the concentration of Eu2O3 increased, the experimental decay curve dropped while the energy transfers efficiency (ɳET) and the energy transfer parameter (Q) raised. Interestingly, the CIE of emission spectra under 393 nm (UV lamp) were reddish orange (0.64, 0.35). The branching ratio (βR) was most significant at 612 nm, and the JO parameter trend was Ω2 > Ω6 > Ω4. Furthermore, all characterizations confirm its applicability in optical display devices. © 2024

Diagnostic Radiology Technology Department College of Applied Medical Sciences Taibah University Madinah Saudi Arabia. Radiologic Sciences Department Faculty of Applied Medical Sciences King Abdul Aziz University Jeddah Saudi Arabia. Radiological Sciences Program Batterjee Medical College Jeddah 21442 Saudi Arabia. College of Applied Medical Sciences King Saud bin Abdulaziz University for Health Sciences Jeddah Saudi Arabia. King Abdullah International Medical Research Center Jeddah Saudi Arabia. Ministry of the National Guard - Health Affairs Jeddah Saudi Arabia.

Background:Interventional radiology (IR) is a subspecialty of diagnostic radiology that uses image-guided radiological methods to carry out minimally invasive procedures. Medical schools in Saudi Arabia minimally expose students to IR unless it is part of an elective rotation. The study aims to gauge how well informed medical and radiology technology students are regarding the variations in educational and clinical experiences offered at different universities in Jeddah, Saudi Arabia. It also aims to assess students' interest in IR as a potential career path and their opinions about their life experiences concerning the department's future. Methods:This study used a cross-sectional study design. Between April and May 2023 in Jeddah, Saudi Arabia, students studying radiology technology and medicine who were in their second year to internship year were given access to a cross-sectional questionnaire. Results:The study found that 31.5% of the students reported having poor knowledge of IR, while 7.8% reported not knowing about it at all. Additionally, 45.9% of respondents felt that their knowledge was adequate, while a minority of 14.7% reported having an excellent understanding of IR concepts. Therefore, in order to enhance students' knowledge about IR, IR courses should be introduced early into curricula, IR symposiums and conferences. Conclusion:The limited exposure of medical and radiology technology students to IR was highlighted. Over one-third indicated interest in IR as a career, with radiology technology students demonstrating greater familiarity. Enhancing IR education through early curriculum integration, symposiums, and conferences is essential. Furthermore, addressing the lack of a standardized radiology curriculum in Saudi medical schools could further enhance IR awareness and career development.

The boro-silicate glasses have been doped with different concentration of Eu2O3 keeping constant CoO concentration (0.02 mol%) and synthesized in melt quench technique, these glasses are characterized through physical parameters, optical absorption, photo, and X-ray luminescence spectroscopy. The results showed that the optical characteristics of the samples are dependent on the Eu2O3 content rather than CoO content inside the glass. We observe tetrahedral dominance of Co2+ in the present glass system. The absorption spectra showed the three broad band of Co2+ ion at 4T1 g(F) → 2T1 g, 4A2 (4F) → 1T1 (4P), and 5T2 g → 5Eg respectively. Using optical absorption spectra, the crystal field parameter (10Dq), Racah parameter (B) were evaluated for all the concentration of Eu3+ doped glass. The phonon side band spectrum shows 1067.98 cm−1 for the present glass system. The integral scintillating efficiency have been studied and exhibited that the value show 8.78 % compared with commercial BGO scintillating crystal. Judd-Ofelt intensity parameters were investigated and used to compute the radiative properties of present glasses. These studies are useful for optimizing glass composition and could be useful for the optical display devices. © 2023 Elsevier GmbH

This paper describes the development and characterization of the Eu3+-doped Ba-Na-B glass system with the varying of Gd2O3 concentrations from 0 to 10 mol%. The photoluminescence emission spectra, excited with 393 nm at Eu3+ ions, show strong luminescence with a peak emission wavelength of 613 nm (5D0→7F2). The highest emission intensity is belonged to the glass sample with 2.5 mol% of Gd2O3. The phonon energy of the host glasses, evaluated from the phonon sideband analysis, is 1017 cm−1. The emission spectra, excited with 275 nm at Gd3+ ions, show the emission band according to the Gd3+→Gd3+ transition at 311 nm (4P7/2→8S7/2) and show the Gd3+→Eu3+ energy transfer, resulting in the emission of light at the characteristic wavelengths of the Eu3+. The highest photoluminescence emission intensity is belonged to the glass sample with 2.5 mol% of Gd2O3, due to its highest energy transfer efficiency at 59.10%. The emitting light of all the glass samples for both excited with 393 nm (Eu3+) and 275 nm (Gd3+) can be all represented by the x,y color coordinates at (0.65, 0.35) in reddish-orange region. The radioluminescence emission spectra, excited by 50 kV, 30 mA X-ray generator, show the emission bands with Eu3+ characteristics. The highest radioluminescence emission intensity is belonged to the glass sample with 7.5 mol% of Gd2O3 with the highest scintillation efficiencies at 20.61% compared to the BGO sample. © 2023 Elsevier GmbH
