Background: Frailty is a complex multi-dimensional state of increased vulnerability to adverse outcomes and is associated with older age but there is growing evidence of accelerated ageing and frailty in non-geriatric populations, including those experiencing socio-economic deprivation and extreme social exclusion, such as people experiencing homelessness. Addiction, as a coping mechanism for prior trauma, is common among people who are homeless and can have a gendered dimension. Women experiencing homelessness and addiction have unique needs which require a gendered approach. The aim of this study is to evaluate the feasibility and impact of an exercise intervention to target the known physical functioning deficits and frailty which this population experiences. Methods: This quantitatively driven, sequential single-arm mixed-methods feasibility study will evaluate the feasibility and impact of a low threshold trauma informed exercise intervention on physical functioning and frailty in women experiencing homelessness and addiction. Physical function (10m Walk Test, 2Min Walk Test, Single Leg Stance, Chair Stand Test, hand grip dynamometry), frailty (Clinical Frailty Scale and the SHARE-Frailty Instrument) and nutritional status (Mini-Nutritional Status), pain (Numerical Rating Scale) and quality of life (SF 12-V2) will be evaluated. The 10-week intervention will involve a 3-times weekly exercise programme with protein supplementation. Following this, qualitative interviews, which will be thematically analysed using Braun & Clarke methodology, will be conducted. This study will be conducted in Dublin from February to July 2024. Discussion: Little is known about frailty-focussed interventions in women experiencing homelessness and addiction. This proposed study will help to increase the knowledge base regarding the physical health burden and frailty experienced by this vulnerable population and will deliver a targeted intervention with a gendered dimension to mitigate its affects. The findings of this research will help narrow the research gap and will guide clinicians and policy makers to implement unique gender-based treatment strategies for this population. (300).

Globally, the major threat is the rise of antimicrobial-resistant diseases and the increasing incidence of cancer, both of which are leading causes of death due to a lack of effective therapies. Nanocomposites (NCs) have recently emerged as an alternative therapeutic agent for the development of novel medications. The current study demonstrates the fast production of Ag-HAp NCs with an aqueous bark extract of Acacia nilotica and evaluates their antiquorum sensing and anticancer activities. UV-vis spectroscopy, Fourier-transformed infrared spectroscopy, X-ray diffraction analysis, zeta sizer, field emission scanning electron microscopy, and high-resolution transmission electron microscopy were used to evaluate the physicochemical and morphological observations of Ag-HAp NCs. The biofabricated NCs demonstrated the ability to inhibit the violacein production in bioreporter strain Chromobacterium violaceum and mitigate the virulent factors in multidrug-resistant Proteus mirabilis. Sub-MIC concentrations of 2% Ag-HAp NCs (80 µg/mL) efficiently decreased the quorum sensing regulated virulence factors such as biofilm formation, exopolysaccharide synthesis, urease, hemolysin, and cell motility, that contribute to antibiotic resistance. Furthermore, an invitro cytotoxicity study of 2% Ag-HAp NCs revealed exceptional anticancer potential against the MCF-7 cell line using MTT assay. The microscopic studies (ROS and DAPI assay) demonstrated that the synthesized NCs elicit cellular cytotoxicity at a low dosage (IC50 − 23.2 µg/mL). All experiments were carried out in triplicate (n = 3) to establish the statistical significance. Thus, phyto-mediated synthesized 2% Ag-HAp NCs are environmentally acceptable and non-toxic nanomaterials suitable for biomedical applications. [ABSTRACT FROM AUTHOR]

In lunar and deep-space farming, saline stress (SS) induced by human urine in hydroponically grown vegetables constitutes one of the prime concerns in its utilization for plant nutrition. Therefore, an indoor hydroponic trial was performed to assess the effectiveness of foliar feeding of citric acid (CA, 50 µM as two sprays at 26 days and 38 days after germination using a common hand-held sprayer) and the control treatment (a standardized plant nutrient with 10% synthetic urine replacement and 50 mM NaCl-induced SS) for sugar beets. The response variables included vegetative growth traits of sugar beets, such as the height of plants and stem girth along with lengths and fresh weights of leaves, roots, and whole plants. The recorded findings demonstrated that at the fourth week of germination, CA foliar feeding did not produce a statistically significant impact on the leaf width and plant height of sugar beets. However, CA produced 17%, 14%, and 35% taller plants at the six, eight, and ten weeks of germination, respectively. Likewise, the control treatment recorded 32% and 30% smaller leaf widths of sugar beets compared to the CA foliar feeding treatment at the 8th and 10th weeks of germination, respectively. In addition, it was found that CA foliar feeding was effective in enhancing the stem length and root length by 16% and 38%, respectively compared to the control under SS. Moreover, CA foliar feeding enhanced stem diameter (26%) and root fresh weight (29%) compared to the control treatment. As far as leaf length and fresh weight along with whole plant fresh weight were concerned, foliar feeding of CA demonstrated its effectiveness by producing 32%, 21%, and 42% greater values, respectively compared to the control treatment. Therefore, CA foliar feeding could serve as a potent strategy to mitigate the deleterious effects of saline stress and boost the vegetative growth of hydroponically grown sugar beets.

Accurate non-line of sight (NLOS) identification technique in ultra-wideband (UWB) location-based services is critical for applications like drone communication and autonomous navigation. However, current methods using binary classification (LOS/NLOS) oversimplify real-world complexities, with limited generalisation and adaptability to varying indoor environments, thereby reducing the accuracy of positioning. This study proposes an extreme gradient boosting (XGBoost) model to identify multi-class NLOS conditions. We optimise the model using grid search and genetic algorithms. Initially, the grid search approach is used to identify the most favourable values for integer hyperparameters. In order to achieve an optimised model configuration, the genetic algorithm is employed to fine-tune the floating-point hyperparameters. The model evaluations utilise a wide-ranging dataset of real-world measurements obtained with a Qorvo DW1000 UWB device, covering various indoor scenarios. Experimental results show that our proposed XGBoost achieved the highest overall accuracy of 99.47%, precision of 99%, recall of 99%, and an F-score of 99% on an open-source dataset. Additionally, based on a local dataset, the model achieved the highest performance, with an accuracy of 96%, precision of 96%, recall of 97%, and an F-score of 97%. In contrast to current machine learning methods in the literature, the suggestion model enhances classification accuracy and effectively addresses the NLOS/LOS identification as a multiclass propagation channel. This approach provides a robust solution with generalisation and adaptability across various dataset types and environments for more reliable and accurate indoor positioning technologies.

Background: Bullying is a harmful behavior that involves repeated aggressive actions intended to cause harm or distress to an individual. It is a major public health concern affecting children and adolescents. There is no local relevant study regarding this issue. Objectives: To determine the prevalence of bullying in primary schools. Materials and methods: A cross-sectional study was carried out from 1st September 2023 to the 10th of April 2024 for a sample consisting of 1216 pupils. The sample of the present study was a group of pupils in fifth and sixth primary school classes for both sexes; those were found in the selected schools out of 201 schools currently found at Al-Najaf city, Iraq. The data collecting tools were direct interviews with the participants and a questionnaire composed of two parts, the first consisting of the demographic characteristics data and the second being the bullying items among primary school pupils. Results: The prevalence of bullying was 81.7%. The study shows 3.5% bullyer, 37.3% bullied, 41% bullyer/victim, and 18.3% were non-victims non bullyer. With the exception of the number of close friends in class, all other items were related to (P-value < 0.05) the prevalence of bullying roles (bullyer, bullied, and bullyer/victim). Conclusion: The study found a high prevalence of bullying among primary school students in Najaf City, which is concerning. An inverse relationship between protective factors and the prevalence of bullying has been identified. To address this, teachers should dedicate class time to discussing the harms of bullying and promote tolerance, while also supporting strategies to reduce school violence. [ABSTRACT FROM AUTHOR]

While agricultural crops remain at the forefront of addressing global food demands and malnutrition, depleting resources, fluctuating climatic conditions, and the adverse impact of biotic/abiotic stresses define a major challenge. Plant seeds comprise an important starting material for plant propagation, in vitro generation, and conservation, and are crucial factors in determining the quality and yield of the desired crops. The expanding horizon of precision agriculture suggests that high-quality seeds could promote crop productivity up to 15–20 percent, attributed to emerging biotechnological innovations in seed science and research. In addition, seed science comprises an integral aspect of sustainable development goals (SDGs), and plays a crucial role in Climate Action (SDG 13) and Zero hunger (SDG 2). While synthetic seed technologies highlight prospects in the propagation and conservation of key plant species, seed biopriming to address environmental stresses is innovative in climate-smart agriculture. The article discusses key developments in advanced seed biotechnologies, ranging from nano-enabled seed treatments to the non-coding RNA-mediated determination of seed traits and genetic manipulation of seeds for quality improvement. Research employing multi-omics, bioinformatics, and seed biopharming for the enhanced production of high-value metabolites is opening new avenues in seed biology and biotechnology research.

This study examines the structural, microstructural, magnetic, and dielectric properties of Cr3+-substituted ferrites, specifically Mg0.5Cu0.5Fe1.5Cr0.5O4 and Mg0.5Zn0.5Fe1.5Cr0.5O4, synthesized using the solid-state reaction method. Structural and phase purity assessments were conducted via x-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR) spectroscopy, and Vibrating Sample Magnetometry. XRD patterns confirmed the formation of a single-phase cubic spinel structure in both ferrites, with derived lattice parameters (8.402 and 8.497 Å) and crystallite sizes (44.70 and 30.05 nm) supporting consistent structural integrity. SEM analysis in association with ImageJ software showed grain sizes between 732 and 324 nm, while FTIR spectra revealed characteristic tetrahedral and octahedral vibration bands. Notably, the saturation magnetization increased significantly with Cu2+ concentration, from 38.67 to 60.45 emu/g, indicating an enhancement in magnetic properties. The dielectric behavior, analyzed over a 100–105 Hz range, exhibited Maxwell–Wagner interfacial polarization and electron hopping effects between Fe2+ and Fe3+ ions, contributing to typical dispersion patterns. This improvement in magnetic and dielectric properties, particularly in the Cu-doped samples, underscores the effectiveness of Cr3+ substitution in tuning material characteristics. The findings suggest that these modified ferrites hold promise for high-frequency electronic applications, such as inductors, transformers, and electromagnetic interference shielding materials, where both magnetic stability and efficient dielectric performance are critical. This research contributes valuable insights into the development of advanced ferrites for multifunctional electronic devices. [ABSTRACT FROM AUTHOR]

Psychological problems experienced by diabetic patients need to be known and handled properly by health workers because distress will have a negative impact on the patient's diabetes management behavior. This study aims to capture and describe in detail the psychosocial experience of diabetes patients. This research is qualitative research with a phenomenological approach. Purposive sampling was used to select participants who had an experience following the phenomenon and research objectives. The number of participants in this study was 10 participants. This research was conducted in the Malang City Ciptomulyo Health Center area from March to May 2021. The analysis of this research was interpretative psychological analysis (IPA). The four themes of the psychosocial experience found in people with diabetes mellitus are fear and worry when diagnosed with diabetes, sad and disturbed by changes in body appearance and function, social support providing appeasement and self-awareness and support of others for diabetes management. Living with diabetes can be a difficult and overwhelming experience that often leads to fear and anxiety. Furthermore, the physical changes caused by diabetes can disrupt daily routines and affect mental health. Health workers should address both the physical and psychological effects of diabetes and encourage patients to take responsibility for their treatment to improve overall health.

(1) Background: Research on mental health literacy (MHL) and attitudes toward mental health problems (ATMHP) among non-medical college students in Nepal is limited. This study examined the relationship between MHL and ATMHP, considering demographic variables and familiarity with mental health issues; (2) Methods: We conducted a cross-sectional survey with 385 college students from Chitwan and Kathmandu, Nepal, using opportunity sampling. Descriptive and inferential statistics examined demographic differences, while Pearson's correlation assessed relationships among latent variables; (3) Results: No relationship was found between MHL and ATMHP (r = −0.01, p = 0.92). Females had greater awareness of stereotypes (p = 0.025, g = 0.24). Hotel management students showed better self-help strategies (p = 0.036, d = 0.46). Public college students scored higher in self-help strategies than government (p = 0.036, d = −0.32) and private college students (p = 0.02, d = −0.32). Non-employed students outperformed employed ones in self-help strategies (p = 0.002, g = −0.46). Other demographic factors showed no significant relationships; (4) Conclusions: MHL and ATMHP were unrelated, indicating that increasing MHL alone may not improve attitudes. Multidimensional interventions combining education and experiential learning are needed. Certain demographic factors influenced stereotypes and self-help strategies, while others showed no significant impact. [ABSTRACT FROM AUTHOR]

Helicobacter pylori is a highly prevalent pathogen in human gastric mucosa epithelial cells with strong colonization ability. Weizmannia coagulans is a kind of active microorganism that is beneficial to the improvement of host gut microbiota balance and can prevent and treat intestinal diseases. We investigated the beneficial effects of W. coagulans BC99 in H. pylori infected mice and measured inflammation response, oxidative stress, and gut microbiota. Results showed that BC99 could alleviate the gastric inflammation, inhibit the increasing of inflammation parameters endotoxin, interleukin‐10, transforming growth factor‐β, and interferon‐γ and oxidative stress myeloperoxidase and malondialdehyde, promote the levels of superoxide dismutase and catalase. Furthermore, 16S rRNA gene sequencing analysis revealed that BC99 reversed the change of gut microbiota by reducing the abundance of Olsenella, Candidatus_Saccharimonas, Monoglobus, and increasing the abundance of Tyzzerella. Meanwhile, BC99 caused elevated levels of Ligilactobacillus and Lactobacillus. In view of the beneficial effect of BC99 on the content of short‐chain fatty acid, valeric acid with sodium valerate interfered with H. pylori infection in mice found that valeric acid had a good restorative effect of H. pylori infection relating inflammation and oxidative stress responses. These results suggest that W. coagulans BC99 can be used as a potential probiotic to prevent and treat H. pylori infection by regulating the inflammation, oxidative stress, and gut microbiota.

This study aimed to estimate the potential optoelectronic and biological properties of AgO:ZnO nanocomposite synthesized by an environmentally friendly method. The synthesis of nanocomposite was carried out by reducing silver nitrate with Salvia hispanica extra, and zinc nitrate was mixed to produce the nanocomposite. An extensive examination was carried out on the physical and biological characteristics of the synthesized nanocomposite using several approaches. The EDX analysis confirmed the purity of the synthesized sample via the presence of elements Ag, Zn, and O only in the nanocomposite. The crystal structure of nanocomposite with hexagonal phase and average crystallite size of 56.8 nm was confirmed by X-ray diffraction. The formation of fibrous AgO:ZnO nanoparticles with an average diameter of 1.021 ± 0.6 μm was indicated by field-emission scanning electron microscopy examination. The optical property investigation revealed that the nanocomposite had a wide absorption band with an absorption peak at 425 nm. The observed phenomenon was attributable to the occurrence of electronic transitions within the material. The direct bandgap energy of 2.90 eV and the Urbach energy of 0.456 eV for the nanocomposite demonstrated the presence of defect states in the bandgap region. The measured values of the conduction band edge (ECB) and valence band edge (EVB) additionally revealed the material's electronic structure. The biological potential of AgO:ZnO nanocomposite was evaluated by the agar well diffusion technique against Gram-positive and Gram-negative bacteria and a fungus. The extensive investigation of the AgO:ZnO nanocomposite's characteristics has shown its potential for use in a wide range of photonic, optoelectronic, and biological applications.

Moreover, with the continuous population increase worldwide, there is more demand of food and other daily necessities, which require double agriculture production to provide adequate food for humanity from the same available natural resources. Therefore, looking for new techniques to combat various challenges is instantly needed to sustain crop production and provide enough food for humanity. The use of nanotechnology in agriculture field represents an important tool for consistent production of agriculture crops and assists farmers with new practice management systems such as precision agriculture systems, the aim of which is to increase productivity and reduce expenses. Nanotechnology plays an important role in altering agriculture food production. The particles ranging from 1 to 100 nm are accounted as nanoparticles, which usually have high surface energy, big surface area and quantum quarantine. Most notably, nanoparticles increase crop yield by increasing the effectiveness of agricultural inputs to enable site-targeted, controlled nutrient delivery, assuring the least amounts of agroinputs needed. Additionally, the main aim in agricultural production is to facilitate plants' faster adaptation to the increasingly severe climate change factors, such as high temperatures, low water availability, salinity, alkalinity and environmental pollution with heavy metals, without jeopardizing the delicate ecosystems that are currently in place. This review illustrates the effect of numerous nanoparticles on diverse plants of many concentrations, sizes and shapes. The molecular and genetic response to NPs, their method of action and their interactions with biomolecules should be the main areas of study in the future. [ABSTRACT FROM AUTHOR]

Globally, African marigold (MG) derived essential oils (EOs) have attained an immense economic pertinence in the flavor, fragrance, food, medicinal, and floricultural industries, which necessitate boosting its production on a commercial scale. Therefore, we aimed to assess varying levels (0, 50, 100, 150, and 200 mg L-1) of exogenously applied melatonin (MT) as a growth hormone to trigger growth, flower yield, and EOs of MG. The MT was applied as a foliar spray after thirty days of transplantation of MG plants and repeated thrice at fifteen-day intervals. The results depicted that exogenous MT (150 mg L-1) recorded the maximum plant height and leaves number along with fresh and dry weights of leaves and roots. The same treatment exhibited 66%, 64%, and 18% higher flower fresh and dry weights and flower yield respectively, than the control. Additionally, MT remained effective in reducing days taken to bud emergence and flowering, while flower retention duration increased by 11 days. Following the trend of vegetative growth traits, foliar-applied MT (150 mg L-1) remained unmatched in terms of physiological attributes (transpiration rate, stomatal conductance, chlorophyll a, and b contents) of MG. Moreover, for EOs extracted from fresh and dry flowers and leaves, this treatment remained effective by producing 77%, 73%, 53%, and 85% higher content, respectively than the control. Finally, the chemical profiling analyses detected eighty-seven chemical constituents (Caryophyllene oxide was the most dominant compound, and cis-Z-alpha-Bisabolene epoxide followed it) in MG flowers. In terms of the retention time of different chemical compounds in MG flowers, Calarene epoxide had the highest retention time of 19.75 minutes among major compounds. Based on these results, 150 mg L-1 dose of MT may be recommended to growers for boosting MG growth, floral yield and EOs content sustainably. [ABSTRACT FROM AUTHOR]

The achievement of global food security faces exceptional challenges due to the rapid population growth, land degradation and climate change. Current farming practices, including mineral fertilizers and synthetic pesticides, alone are becoming insufficient to ensure long-term food security and ecosystem sustainability. The lack of robustness and reliability of conventional approaches warrants efforts to develop novel alternative strategies. Bio-based management strategies offer promising alternatives for improving soil health and food productivity. For example, microbial inoculants can enhance nutrient availability, crop production and stress resistance while also remediating contaminated soils. Nanobiotechnology is a promising strategy that has great potential for mitigating biotic and abiotic stresses on plant toward sustainable agriculture. Biochar (including modified biochar) serves as an effective microbial carrier, improving nutrient availability and plant growth. Also, biochar amendments have been demonstrated to have great potential facilitating soil organic carbon sequestration and mitigating greenhouse gas emissions and therefore contribute to climate change mitigation efforts. This review examines the integration of microbial inoculants, nano-fertilizers and biochar, which demonstrates as a promising strategy to enhance soil health, crop productivity and environmental sustainability. However, overcoming challenges related to their mass production, application and potential risks remains crucial. Future research should focus on optimizing these bioamendment strategies, evaluating their economic viability and developing robust regulatory frameworks to ensure safe and effective agricultural implementation.

Designing a fractal antenna for white space TV band frequencies is the main goal of the suggested work. In this design 4 iteration Koch snowflakes patch is used to get multiband. As the number of iterations increased size of the antenna is going to reduce. Further 4th iteration Koch snowflakes slots have been created in the patch. By introducing a fourth iteration cross slot into the ground plane, three bands have been created. Circular polarisation is attained through the incorporation of cross slots in the ground plane, inducing a phase shift between vertically and horizontally polarised electromagnetic waves. The antenna primarily operates within the last frequency bands (686–806 MHz) with linear polarisation. However, it can also function in the initial frequency band (487–540 MHz) with left-hand circular polarisation. The physical size if antenna is reduced by 38 mm with a gain of 4.5dBi. Axial ratio bandwidth (481–552 MHz) is 71 MHz. Axial ratio bandwidth is 18 MHz more as compared to impedance bandwidth. The same antenna can work in linear polarisation as well as circular polarisation. Multi-polarised, multiband antenna with impedance bandwidth of 10.3% (1st band) and 16.08% (last band) is designed for white space TV band frequencies. [ABSTRACT FROM AUTHOR]

Researchers have repeatedly emphasized how urgently we have to decrease the massive nitrogen fertilizer consumption to support agricultural productivity and maintain a sustainable ecosystem. Using chitosan (CS) as a carrier for slow release is considered a potential tool for reducing synthetic fertilizer and improving crop productivity. Therefore, two field experiments were arranged in a randomized complete block design to investigate the effects of seven treatments including synthetic fertilizer and exogenous application of chitosan-based NPK nano-structure (Ch/NPs-NPK) on growth, productivity, and nutrient uptake traits of rice as a worldwide strategy crop during 2022 and 2023 growing seasons. The experimental treatments were: T1 = full recommended synthetic NPK (recommended urea, superphosphate, potassium sulfate; control treatment), T2 = 70% of T1 + Ch/NPs-NPK 100 ppm, T3 = 70% of T1+ Ch/NPs-NPK 200 ppm, T4 = 70% of T1+ Ch/NPs-NPK 300 ppm, T5 = 30% of T1+ Ch/NPs-NPK 100 ppm, T6 = 30% of T1+ Ch/NPs-NPK 200 ppm, and T7 = 30% of T1 + Ch/NPs-NPK 300 ppm. The results revealed that T4 (i.e., 70% of recommended NPK+ Ch/NPs-NPK 300 ppm) and T1 (full recommended synthetic NPK) resulted in the highest and most significant growth and yield traits of rice as well as nutrient grain contents compared to other treatments. Therefore, combining 70% of recommended NPK with Ch/NPs-NPK 300 ppm as an exogenous application can be a smart choice for reducing synthetic NPK fertilizers by 30% in paddy fields without producing a significant decline in terms of growth, yield characteristics, or nutrient grain contents when applying the full recommended synthetic NPK.

Introduction: CEP-37440 was synthesized and supplied by the research and development division of Teva Branded Pharmaceutical Products (West Chester, PA, United States). CEP-37440 represents a newly developed compound that exhibits selectivity inhibition of Focal Adhesion Kinase and Anaplastic Lymphoma Kinase FAK/ALK receptors, demonstrating novel characteristics as an orally active inhibitor. The simultaneous inhibition of ALK and FAK can effectively address resistance and enhance the therapeutic efficacy against tumors through a synergistic mechanism. Methods: The objective of this research was to create an LC-MS/MS method that is precise, efficient, environmentally friendly, and possesses a high level of sensitivity for the quantification of CEP-37440 in human liver microsomes (HLMs). The aforementioned approach was subsequently employed to evaluate the metabolic stability of CEP-37440 in HLMs in an in vitro setting. The validation procedures for the LC-MS/MS analytical method in the HLMs were performed following the bio-analytical method validation guidelines set out by the US-FDA. The AGREE program was utilized to assess the ecological impacts of the current LC-MS/MS methodology. Results and Discussion: The calibration curve linearity was seen in the range of 1–3000 ng/mL. The inter-day accuracy (% RE) exhibited a range of −2.33% to 3.22%, whilst the intra-day accuracy demonstrated a range of −4.33% to 1.39%. The inter-day precision (% RSD) exhibited a range of 0.38% to 3.60%, whilst the intra-day precision demonstrated a range of 0.16% to 6.28%. The determination of the in vitro half-life (t1/2) and moderate intrinsic clearance (Clint) of CEP-37440 yielded values of 23.24 min and 34.74 mL/min/kg, respectively. The current manuscript is considered the first analytical study for CEP-37440 quantification with the application to metabolic stability assessment. These results suggest that CEP-37440 can be categorized as a pharmaceutical agent with a moderate extraction ratio. Consequently, it is postulated that the administration of CEP-37440 to patients may not lead to the accrual of dosages within the human organs. According to in silico P450 metabolic and DEREK software, minor structural alterations to the ethanolamine moiety or substitution of the group in drug design have the potential to enhance the metabolic stability and safety profile of novel derivatives in comparison to CEP-37440.

Lung cancer (LC) is the leading cause of cancer‐related mortality worldwide. Radiotherapy is the main component of LC treatment; however, its efficacy is often limited by radioresistance development, resulting in unsatisfactory clinical outcomes. Here, we found that LC radiosensitivity is up‐regulated by decreased expression of long‐chain acyl‐CoA synthase 6 (ACSL6) after irradiation. Deletion of ACSL6 results in significant elevation of Friend leukemia integration 1 transcription factor (FLI1) and a marked decline of collagens (COLs). Blocking of ACSL6 impairs the tumor growth and upregulates FLI1, which reduces the levels of COLs and compromises irradiation‐induced autophagy, leading to considerable therapeutic benefits during radiotherapy. Moreover, the direct interaction between ACSL6 and FLI1 and engagement between FLI1 and COLs indicates the involvement of the ACSL6‐FLI1‐COL axis. Finally, the potently adjusted autophagy flux reduces its otherwise contributive capability in surviving irradiation stress and leads to satisfactory radiosensitization for LC radiotherapy. These results demonstrate that enhanced ACSL6 expression promotes the aggressive performance of irradiated LC through increased FLI1‐COL‐mediated autophagy flux. Thus, the ACSL6‐FLI1‐Col‐autophagy axis may be targeted to enhance the radiosensitivity of LC and improve the management of LC in radiotherapy. [ABSTRACT FROM AUTHOR]

Highlights: Recent advancement in solution-processed thin film transparent photovoltaics (TPVs) is summarized, including perovskites, organics, and colloidal quantum dots. Pros and cons of the emerging TPVs are analyzed according to the materials characteristics and the application requirements on the aesthetics and energy generation. Promising TPV applications are discussed with emphasis on agrivoltaics, smart windows and facades. Electrical energy is essential for modern society to sustain economic growths. The soaring demand for the electrical energy, together with an awareness of the environmental impact of fossil fuels, has been driving a shift towards the utilization of solar energy. However, traditional solar energy solutions often require extensive spaces for a panel installation, limiting their practicality in a dense urban environment. To overcome the spatial constraint, researchers have developed transparent photovoltaics (TPV), enabling windows and facades in vehicles and buildings to generate electric energy. Current TPV advancements are focused on improving both transparency and power output to rival commercially available silicon solar panels. In this review, we first briefly introduce wavelength- and non-wavelength-selective strategies to achieve transparency. Figures of merit and theoretical limits of TPVs are discussed to comprehensively understand the status of current TPV technology. Then we highlight recent progress in different types of TPVs, with a particular focus on solution-processed thin-film photovoltaics (PVs), including colloidal quantum dot PVs, metal halide perovskite PVs and organic PVs. The applications of TPVs are also reviewed, with emphasis on agrivoltaics, smart windows and facades. Finally, current challenges and future opportunities in TPV research are pointed out.
