4 mm, respectively for the E-Frame mask. The random error of the E-Frame masks in the SI direction was significantly smaller than that of the Type-S. The number of cases showing displacements exceeding 10 mm in the SI direction for at least one fraction was eight (61% of 13 cases) and three (25% of 12 cases) for Type-S and E-Frame masks, respectively. Conclusions The E-Frame masks reduced the random displacements of patient's shoulders in the SI direction, effectively preventing large shoulder shifts that occurred frequently with Type-S masks.Purpose This study aims to investigate the impact of the cavity on the sinus wall dose by comparing dose distributions with and without the sinus under magnetic fields using Monte Carlo calculations. Methods A water phantom containing a sinus cavity (Empty) was created, and dose distributions were calculated for 1, 2, and 4 irradiation fields with 6 MV photons. The sinus in the phantom was then filled with water (Full), and the dose distributions were calculated again. The sinus was set to cubes of 2 cm and 4 cm. The magnetic field was applied to the transverse and inline direction under the magnetic flux densities of 0 T, 0.35 T, 0.5 T, 1.0 T, and 1.5 T. The dose distributions were analyzed by the dose difference, dose volume histogram, and D2 with sinus wall thicknesses of 1 and 5 mm. Results D2 in the "Empty" sinus wall under transverse magnetic fields for the 1-field and 4-field cases was 51.9% higher and 3.7% lower than that in the "Full" sinus wall at 1.5 T, respectively. Meanwhile, D2 in the Empty sinus wall under inline magnetic fields for 1-field and 4-fields was 2.3% and 2.6% lower than that in the "Full" sinus at B = 0 T, respectively, whereas D2 was 0.9% and 0.7% larger at 1.0 T, respectively. Conclusions The impact of the cavity on the sinus wall dose depends on the magnetic flux density, direction of the magnetic field and irradiation beam, and number of irradiation fields.Lead is highly toxic. The detection of lead in the environmental bodies is difficult, because it is colourless and odourless. Herein, we report the synthesis of gold nanoparticles (AuNPs) using the interdigitized vesicles formed by N-decanoyltromethamine (NDTM). AuNPs stabilized by NDTM was pink in colour with spherical shape and the size is 29 ± 7 nm. The optical property of the NDTM-AuNPs was explored for the first time to detect toxic chemical, Pb2+. The addition of toxic metal ion Pb2+ to NDTM-AuNPs rapidly ( less then 1 min) alters the colour from pink to violet due to aggregation, which was confirmed by particle size analyser and TEM. The aggregation induced colour changes were realized via broad spectra in UV-Vis spectroscopy. NDTM-AuNPs showed a selective and sensitive spectrophotometric signal with Pb2+ when compared with other metal ions. The colorimetric change as a function of Pb2+ concentration gave a linear response in the range of 0-30 μM (R2 = 0.9942). The detection limit was found at 10 μM by naked eye and 0.35 μM by spectrophotometry. The proposed method was successfully applied for the determination of Pb2+ ions in tap water and sewage water. Moreover, as a proof of concept, the NDTM-AuNPs sensor system was applied for the detection of lead in commercial paints. The results of the quantitative estimation of lead in paints by NDTM-AuNPs colorimetric sensor were as good as the standard method, atomic absorption spectroscopy.Asenapine maleate was approved by the FDA for the treatment of schizophrenia and mania or mixed episodes with bipolar I disorder. In the present article, two spectroscopic methods were developed and validated for the determination of asenapine. Both methods depend on association complex formation between xanthine based dye (eosin Y) and the cited drug in acetate buffer pH = 3.8. In the spectrophotometric method (method I), the absorbance of the formed complex was estimated at maximum wavelength of 545 nm and Beer's law was obeyed in the range of 1-12 μg mL-1. The spectrofluorimetric method (method II) depends on measuring the quenching effect of the drug on the native fluorescence of eosin Y at 545 nm after excitation at 303 nm. The linearity range of method II was 0.4-3.2 μg mL-1. The limits of detection were 0.24 and 0.08 μg mL-1 for method I and II, respectively. The instructions of ICH were followed to fully validate the developed analytical procedures. The formation constant of the reaction was 3.93 × 104 while its Gibb's free energy was -2.6 × 104 J mol-1. Finally, the methods were applied for the analysis of pharmaceutical tablets and for evaluation of their content uniformity.The influence of furo-, thieno-, and benzo-fused structures at the b bonds in the BODIPY frame on the optical properties is investigated by TD-CAM-B3LYP and RI-CC2 calculations. The most important result is that substituents at the b bond of the BODIPY core affect strongly the S1-S2 gaps. In contrast to the S1 (local excited (LE-type)) state, energy of which is nearly the same for all the substituents at the b bond, energy of the S2 (charge transfer (CT-type)) state depends strongly on the nature of the substituent and decreases in the following order furo-fused > thieno-fused > benzo-fused. In the last case the inversion of S1 and S2 levels occurs. No red shift of the main long-wave absorption transition and no substantial changes in its intensity can be predicted by the calculations for benzo[b]-derivative (vertical energy (Ev) is 2.95 eV, oscillator strength (f) is 0.80) relative to furo- (Ev = 2.97 eV, f = 0.69) and thieno-derivatives (Ev = 2.95 eV, f = 0.65). However, the dramatic decrease of the fluorescence quantum yield is expected owing to positions of their LE-type (Ev = 2.95 eV, f = 0.80) and CT-type (Ev = 2.79 eV, f = 0.01) transitions. In the case of thieno-fused BODIPY, owing to the approach of the energy levels of the vertical S2 and S1 states, the energy equilibrium of the [1]CT-type state becomes lower than that of the [1]LE state, and Φf of the thieno-derivative may be substantially lower than Φf of the furo-derivative.A naturally fluorescent cyanobacterial protein C-phycoerythrin (CPE) was investigated as a fluorescent probe for biologically and environmentally important hydrosulphide (HS-) ion. It was selective for HS amongst a large anion screen and the optical response was rapid. Sequential UV-visible titration showed considerable peak shift and attenuation with increasing [HS-] while fluorescence titration proved that HS- quenched CPE fluorescence in a concentration dependent manner. The linear response range was 0-2 mM HS- while the Stern Volmer curve was non-linear and the limit of detection was 185.12 μM. Except bicarbonate and glycine, no anion or biomolecule interfered with the detection even at 10 times the concentration of HS-. It was also free of influences from other sulphur forms like sulphite, sulphate and thiosulphate. CPE reliably detected HS- in freshwater and effluent samples, though some under- and over - estimation was evident. The % recovery ranged from ~96 to 105% (RSD ~ 0.035-0.188%). FTIR analysis showed significant changes in the amide I and II regions of CPE, along with minor modifications in the amide III region as well, showing that HS- was able to influence the protein secondary structure at higher concentrations.A simple and green approach for the synthesis of photoluminescent N,S-carbon dots (N,S-CDs) has been proposed using a single natural source precursor (bamboo leaf) as raw materials. The as-synthesized N,S-CDs exhibited a highly stable, excitation wavelength-dependent emission, excellent photobleaching, alkali, and salt tolerance. Here, the mechanism of N,S-CDs luminescence was studied via the UV-vis absorption spectrum and photoluminescence spectroscopy. Based on the quenching properties of nitrophenol compounds on the fluorescence of N,S-CDs, the interaction between N,S-CDs and nitrophenol compounds was investigated on detail in aqueous solution. More importantly, the study on photophysical properties of the N,S-CDs may provide the basis for the development of the N,S-CDs for the fluorescent probe of nitrophenol compounds.Squarylium-based colorimetric hydrogen sulfide (H2S) chemosensors (SQ1, SQ2, and SQ3) were developed, and their detection properties were systematically characterized. SQ1 exhibited rapid and high resolution H2S sensing properties through significant color changes detectable by naked-eye with limit of detection as low as 7.2 ppb. SQ1 also showed excellent selectivity for H2S detection over other relevant anions and nucleophiles. Sensing mechanisms of SQ1 were investigated based on spectroscopic and 1H NMR analyses with quantum calculations. Furthermore, SQ1 showed an efficient response to H2S under versatile conditions in the solution, solid, and dyed fabric states, which suggests applicability of SQ1 to simple, low-cost, and practical H2S sensors.In this study, we report a new donor-acceptor (D-A) type stimuli-responsive material, (E)-4-(((9-ethyl-9H-carbazol-2-yl)methylene)amino)benzoic acid (C1), which possesses both aggregation-induced emission (AIE) and intramolecular charge transfer (ICT) natures. It glows green photoluminescence which changes into yellow color in response to mechanical stimuli, and fumigation in volatile organic compounds (VOCs) can switch the emission back to the initial state with high reversibility. In addition, the C1 film glows yellow-orange light, but turns into blue emission under continuous fumigation in ethyl acetate vapor. AZD1480 However the vapochromism behaves different when the C1 film is smeared The emission of the smeared film is similar to the unsmeared but changes into cyan color after fumigation. The differences in vapochromism between smeared and unsmeared film can be easily distinguished by naked eyes. As revealed by SEM, the as-prepared film undergoes a morphology change from ill-shaped particles to microspheres in response to organic vapor, while the smeared film with scratched surface changes into dendritic patterns. According to the morphology study, the vapochromic luminescence can be ascribed to the physical adsorption of ethyl acetate vapor and the resulting change in the ICT process. In light of the unique vapochromism of C1, a new encryption-decryption technique for data recording was developed. Information can be recorded on the C1 film by mechanical writing and simultaneously concealed. It can be only accessed via fumigation in organic vapor, demonstrating a reliable steganography technology.This study used a descriptive, correlational, and cross-sectional research design to evaluate the effect of seizure self-efficacy of children with epilepsy on their perceived stigma of seizure. The study was conducted with 303 children with epilepsy. The data of the study were collected using "the Seizure Self-Efficacy Scale for Children" and "the Scale for Perceived Stigma in Children with Epilepsy". The mean age of the children included in the study was 12.65 ± 2.37. The correlation between seizure self-efficacy of the children and their perceived seizure stigma was examined; a strong, significant, and negative correlation was found. It is recommended that the awareness of all health professionals should be increased in approaching children with epilepsy and that self-efficacy and stigma should be addressed.
