Background: Quality of life (QoL) is a term used to evaluate general well-being, and it is defined as ‘the degree to which an individual enjoys his or her life. Within the realm of medicine, the evaluation of QoL frequently involves examining how disease exerts a detrimental impact, diminishing the enjoyment and fulfilment experienced by the individual. Dermatological diseases have been found to exert a substantial negative influence on the QoL of dogs and their owners due to nuisance and stress related to the disease but also due to the caregiver burden. In the management of bacterial skin infections, topical therapy is commonly administered alongside systemic antibiotics. Nonetheless, the protracted duration of treatment and difficulties in ensuring owner compliance can introduce a significant caregiver burden, potentially exacerbating the challenges associated with these conditions. Purpose: This study aimed to evaluate the impact on the quality of life (QoL) of dogs with dermatologic diseases after fluorescent light energy (FLE) treatment. Methods: The study was an open, prospective, multicentric clinical trial that included dogs with various dermatological conditions. The dogs received FLE treatment once weekly until the clinical resolution was achieved. Owners completed a validated questionnaire to assess the QoL of their dogs before and after therapy. Results: Thirty-five dogs with deep pyoderma, interdigital furunculosis, pyotraumatic dermatitis, wounds and perianal fistulas were included. All dogs received two sessions of fluorescent light energy once a week. Median treatment duration was 9 weeks for perianal fistula, 7 weeks for interdigital furunculosis, 5 weeks for deep pyoderma, 3 weeks for wounds and 1.5 weeks for pyotraumatic dermatitis. Complete remission was noted in 86% of dogs, and 14% showed an improvement but partial remission. The majority of owners reported a positive impact on their dogs’ QoL after therapy, and 74% of the dogs showed at least a 50% reduction in QoL scores. Conclusion: Fluorescent light energy has been shown to exert beneficial effects on the healing of dermatological diseases and the quality of life (QoL) in dogs and their owners, whether used as a standalone treatment or in combination with standard care therapies. Additionally, it was well-tolerated by the dogs. This study emphasizes the significance of considering both the owner’s and dog’s QoL when evaluating the therapeutic efficacy of dermatological treatments. 展开更多

The complete decomposition of formaldehyde(HCHO) at ambient temperature is the most potential strategy for HCHO elimination from indoor environment.Herein,extra low content of Pt nanoparticles(0.025 wt%)supported on water-solubility carbon nitride/ceria(Pt/gC_(3)N_(4)@CeO_(2)) was prepared for gaseous HCHO removal at ambient temperature in a simulated indoor environment.Fluorescent light(8 W) illumination could visibly boost the complete decomposition of HCHO into CO_(2) over Pt/gC_(3)N_(4)@CeO_(2).The cooperative effect in the distinct heterostructure and plenty of surface reactive oxygen species contribute primarily to the enhanced catalytic performance of Pt/g-C_(3)N_(4)@CeO_(2).Moreover,the possible mechanism of HCHO oxidation over Pt/g-C_(3)N_(4)@CeO_(2) assisted by the fluorescent light irradiation was proposed based on the physicochemical and optical characterization as well as the result of in situ diffuse reflectance infrared Fourier transform spectra.This work might shed some light on the potential application of the versatile catalysts for ambient-temperature catalytic decomposition of HCHO by making full use of the indoor energies. 展开更多

A new one-dimensional Mn(Ⅱ) complex, [MnL2(bipy)(H2O)2]n 1, has been obtained by the reaction of MnCl2·4H2O, 2,2'-bipyridine (bipy) and 1-(4-phenoxyacetate)-5-thioacetatetetrazole (H2L). The crystal crystallizes in the triclinic system, space group Pi with a = 7.6088(2), b = 12.2795(2), c = 13.6617(3)A, α = 75.416(2), β =79.264(2), γ = 74.271(2)°, V = 1179.48(4) A3, Z = 2, Mr = 555.43, F(000) = 570, Dc = 1.564 g/cm^3, μ = 0.704 mm^-1, the final R = 0.0454 and wR = 0.0849 for 3127 observed reflections (Ⅰ〉 2σ(Ⅰ)). The Mn(Ⅱ) is six-coordinated by two water molecules, two N atoms from bipy and two carboxylate O atoms from two L^2- to form a distorted octahedral geometry. Each L^2- ligand serves as a bridging ligand to link two Mn(Ⅱ) atoms, leading to a single-strand zigzag coordination polymer. Hydrogen-bonding interactions between adjacent chains as well as π-π stacking interactions extend the complex into a three-dimensional supramolecular architecture. Moreover, the title compound emits strong red fluorescent light (λem(max) = 610 nm) in EtOH solution. 展开更多

A series of isostructural d/f molecular compounds Zn(H2L)Ln(NO3)3·CH3OH(Ln = Dy(1), Tb(2) and Sm(3)) were synthesized by the introduction of a designed multifunctional ligand N,N?,N??,N???-tetra(2-hydroxy-3-methoxy-5-methylbenzyl)-1,4,7,10-tetraazacyclododecan(H4L = C(44)H(60)N4O8). In the isostructural molecules, each crystallographically independent Zn2+ and Ln3+ centers are connected by two phenolic oxygen atoms. For the six-coordinate Zn-(2+) ion, the coordination geometry can be viewed as a regular bicapped square pyramid. While for the ten-coordinate Ln-(3+) ion, if each O,O?-chelated nitrate ligand is seen as a single coordination site, the coordination geometry can be viewed as a distorted pentagonal bipyramid. The fluorescent spectra show that compounds 2 and 3 exhibited characteristic sharp emissions of Tb-(3+) and Sm-(3+), respectively, while compound 1 was found to be a single-component white-light-emitting complex in the solid state. Thermal stabilities of the three compounds were investigated by using thermal gravimetric analysis. In addition, the thermal decomposition of compound 1 was confirmed by temperature-dependent powder X-ray diffraction technique. 展开更多

Exploring an alternative strategy with high efficiency and low cost to abate formaldehyde(HCHO)in indoor environment,is of increasing significance for people’s health.CeO_(2) catalysts prepared by hydrothermal,precipitation and calcination methods were investigated for HCHO removal at ambient temperature.It is found that indoor fluorescent light visibly boosts the catalytic performance of CeO_(2) catalysts for HCHO decomposition at ambient temperature.Among the CeO_(2) catalysts,CeO_(2) prepared from hydrothermal method(CeO_(2)-H)exhibits a superior catalytic performance and an excellent durability by eight recycle times.Based on the characterization and analysis,the excellent catalytic performance of CeO_(2)-H is mainly contributed by its abundance of surface oxygen vacancies,and photogenerated electrons and hole activated by fluorescent light.This work shows a potential practicability in HCHO pollution elimination by taking full advantage of the existing lighting in indoor environments. 展开更多

Storing reclaimed water in lakes is a widely used method of accommodating changes in the consumption of reclaimed water during wastewater reclamation and reuse. Solar light serves as an important function in degrading pollutants during storage, and its effect on dissolved organic matter(DOM) was investigated in this study. Solar light significantly decreased the UV_(254) absorbance and fluorescence(FLU) intensity of reclaimed water.However, its effect on the dissolved organic carbon(DOC) value of reclaimed water was very limited. The decrease in the UV_(254) absorbance intensity and FLU excitation–emission matrix regional integration volume(FLU volume) of reclaimed water during solar light irradiation was fit with pseudo-first order reaction kinetics. The decrease of UV_(254) absorbance was much slower than that of the FLU volume. Ultraviolet light in solar light had a key role in decreasing the UV_(254) absorbance and FLU intensity during solar light irradiation. The light fluence-based removal kinetic constants of the UV_(254) and FLU intensity were independent of light intensity. The peaks of the UV_(254) absorbance and FLU intensity with an apparent molecular weight(AMW) of 100 Da to 2000 Da decreased after solar irradiation, whereas the DOC value of the major peaks did not significantly change. 展开更多

Using a measurement system based on fluorescence induced by variable pulse light, photosynthesis parameters of chlorella pyrenoidosa are obtained, employing single-turnover and multiple-turnover protocols under darkadapted and light-adapted conditions. Under the light-adapted condition,σ’PSII is larger, and F’v/F’m(ST) and F’v/F’m(MT) are smaller than those of the dark-adapted condition, but the corresponding parameters possess good linear correlations.Fm(MT), F’m(MT), Fv/Fm(MT) and F’v/F’m(MT) which are measured using the multipleturnover protocol, are larger than those of the single-turnover protocol. The linear correlation coefficient between Fm(ST) and Fm(MT) is 0.984,and Fv/Fm(MT) = 1.18 Fv/Fm(ST) The linear correlation coefficient between F’m(ST) and F’m(MT) is 0.995, and F’v/F’m(MT) = 1.36 F’v/F’m/(ST). 展开更多
