“…Smart windows that block UV rays may help prevent sunburn, skin cancer, and erythema. [ 44 ] According to the results summarized in Table 4, a variety of LdAN ratios were used to test the UV shielding properties of the LdAN@PET sheets. PET‐0.5 has a much higher UV blocking capacity than PET‐0 because of the high UV absorbance of LdAN immobilized in PET.…”

Smart window can be defined as switchable material whose light transmission is altered upon exposure to light, voltage, or heat. However, smart windows are usually produced from expensive and breakable glass materials. Herein, transparent smart window with long-persistent phosphorescence, high optical transmittance, ultraviolet (UV) protection, rigid, high photostability and durability, an d superhydrophobicity was developed from recycled polyester (PET). Recycled polyester waste (RBW) was simply immobilized with different ratios of lanthanide-doped aluminate nanoparticles (LdAN) to provide a long-persistent phosphorescent polyester smart window (LdAN@PET) with an abili ty to persist emitting light for extended time periods. The solid-state high temperature technique was used to prepare lanthanide-doped aluminate (LdA) micro-scale powder. Then, the top-down technique was applied to afford the corresponding LdAN. Recycled shredded recycled polyester bottles were charged into a hot bath to provide a clear plastic shred bulk, which was then well-mixed with LdAN and drop-casted to provide long-persistent luminescent smart window. In order to improve the phosphor dispersion in the PET bulk, LdAN was synthesized in the nanoparticle form which was characterized utilizing transmission electron microscopy (TEM). For better preparation of translucent smart window of long-persistent phosphorescent polyester, LdAN must be homogeneously dispersed in the PET matrix without agglomeration. The morphology and chemical composition were studied by Fourier-transform infrared (FTIR) spectra), X-ray fluorescence (XRF) analysis, scanning electron microscopy (SEM), and energy-dispersion X-ray spectroscopy (EDX). In addition, spectral profiles of excitation and emission, and decay and lifetime were used to better understand the photoluminescence properties. The hardness properties were also investigated. The developed phosphorescent transparent polyester smart window demonstrated a color switch to intense green underneath UV irradiation and greenish-yellow under darkness as verified by CIELab color parameters. The afterglow polyester smart window showed an absorption wavelength at 365 nm and two phosphorescence intensities at 442 and 512 nm. An enhanced UV protection, photostability and hydrophobic activity were detected. The luminescent polyester substrates with lower LdAN ratios demonstrated rapid and reversible

“…Skin tissue (0.7 × 0.7 cm) was collected from the mid-dorsal region of the nude mice and fixed in a 4% neutral formaldehyde fixative for 24 h. The tissue was then dehydrated using a gradient elution of ethanol (100%, 95%, 85% and 70%) for 5 min, embedded in paraffin, and cut into a thickness of 4 μm using a SSMT-189 KD2260 microtome (Kedi Instrument Equipment Co., Ltd, Jinhua, Zhejiang, China). 26 These sections were stained with hematoxylin for 3 min, immersed in 1% acid alcohol for 30 s, rinsed with running tap water and stained with eosin for 2 min, and then dehydrated with an ethanol gradient elution (70%, 80%, 90% and 100%), and then mounted with DPX (dibutyl phthalate polystyrene xylene) and observed for epidermal hyperplasia. To observe the integrity of collagen fibers, these sections were first stained with Weigert's iron hematoxylin solution for 10 min, rinsed with running tap water, stained with the Beibrich Scarlet-Acid Fuchsin solution for 10 min, and transferred to aniline blue solution and stained for 10 min, and then rinsed in distilled water, differentiated with 1% acetic acid solution for 5 min, dehydrated using 95% ethanol, cleared in xylene and mounted in DPX.…”

“…In this regard, a number of studies have reported that the release of lower eNOS levels can promote cancer cells cycle progression and proliferation [21][22][23]. On the other hand, a plethora of recent evidence has linked eNOS up regulation to carcinogenesis [18,24,25]. Similarly, studies have shown that direct inducible nitric oxide synthase (iNOS) transduction could be cytotoxic and thus leads to inhibit the growth of tumour cells [26].…”

Globally, breast cancer is the common malignancy affecting women and understanding its associated molecular events could help in disease prevention and management strategies. The present study was set to investigate an association between total antioxidant capacity (TAC) and endothelial nitric oxide synthase (eNOS) polymorphisms with breast cancer. For this purpose, 100 subjects were participated in this work, including 50 female patients diagnosed with breast cancer recruited from Oncology hospital, Baghdad - Iraq and 50 healthy women as a control group. The concentration of antioxidants was measured in the serums collected from blood samples of breast cancer patients and healthy controls. While eNOS SNPs (rs1799983, G894T and rs2070744, T 786C) were assessed using TaqMan SNP genotyping and utilising genomic DNA extracted from the participants. The results showed that the antioxidants levels were significantly (P˂0.0001) reduced in blood samples of breast cancer patients in comparison to that of that healthy controls (0.144± 0.097 and 0.587±0.239 respectively). Additionally, the homozygous GG genotype G894T (rs1799983) could retain beneficial impact for the protection from breast cancer potential. While SNP genotyping results showed that both of the homozygous CC and heterozygous TC genotypes (rs2070744 T >C SNP) seem to contribute to the susceptibility of breast cancer development in the investigated set of patients. Overall, the present study findings suggest an association between reduced antioxidant capacity and eNOS gene polymorphisms in breast carcinogenesis.
