Upadacitinib has demonstrated efficacy in psoriatic arthritis in clinical trials, but its real-world performance in difficult-to-treat PsA remains underexplored. This observational, multicenter, open-label study evaluated the efficacy and safety of upadacitinib in 134 patients with psoriatic arthritis (97 women, mean age 51.8 ± 11.2 years, mean disease duration 9.94 ± 7.72 years) who showed inadequate response to advanced therapies. Most patients (74.6%) had received at least two biological/targeted synthetic disease-modifying antirheumatic drugs with different mechanisms of action. Upadacitinib was initiated at 15 mg daily, and within one month, significant improvements were observed: DAS28-ESR decreased from 4.7 to 3.77 (p < 0.001), DAPSA from 25 to 17 (p < 0.001), and CRP from 2.90 to 1.50 mg/L (p = 0.001). These reductions persisted throughout the study. Prednisone dosage decreased significantly (p = 0.049). Adverse events led to upadacitinib discontinuation in 8.2% of patients, but no serious adverse events were reported. Compared to the SELECT-PsA 2 trial, our cohort had a higher proportion of females and greater prior exposure to biologic agents but showed comparable efficacy and safety outcomes. These findings suggest that upadacitinib is a rapid, effective, and relatively safe therapeutic option for difficult-to-treat psoriatic arthritis under real-world conditions, supporting its use despite differing patient characteristics from clinical trial populations.

Thyroid disease is a health concern related to the thyroid gland, which is vital for controlling the metabolism of the human body. Predominantly affecting women in their fourth or fifth decades of life, thyroid disease can result in physical and mental issues. This research focuses on improving the diagnostic process by creating a classification model that utilises various machine learning models and a deeplearning model to categorise three types of thyroid disease conditions. This research developed an automated system capable of classifying three thyroid conditions using five machine learning models and a deep learning model. Resampling techniques, such as SMOTE oversampling and Random undersampling, are utilised to correct the issue of class imbalance in the dataset. Finally, a web-based application is developed utilising the most effective model, GBC, which facilitates easy classification of thyroid diseases. The experimental analysis showed that the Gradient Boosting Classifier (GBC), using oversampling techniques, achieved the highest level of performance in classifying thyroid diseases, obtaining an accuracy and F1-Score of 99.76%. This study demonstrated that TSH was the most indicative biomarker for thyroid disease classification. The experimental results proved that the Gradient Boosting Classifier (GBC) utilising the oversampling technique achieved a superior performance compared to other classifier models, with an accuracy and F1-Score of 99.76%. This research presented insights that can assist healthcare practitioners in promptly diagnosing thyroid diseases. Full article

Fossil fuels remain essential to the world’s energy supply, but the decline in the quality of the oil extracted has increased the relevance of processes such as hydrocracking. Despite its potential, this process involves high energy consumption. In order to assess its efficiency, an exergy analysis of a conventional hydrocracking unit was carried out using Computer Aided Process Engineering (CAPE) tools. After simulations, the physical and chemical exergies of the input and output streams were calculated, which showed a remarkable energy efficiency of 98.76%, attributable to the high exergy content of the products obtained (171,243,917.70 MJ/h) compared to the residues generated (1,065,290.8 MJ/h). The most significant irreversibilities were found in the Recycle Gas Sweetening stage, while the lowest exergy efficiency, 87.16%, was observed in the Residual Gas Sweetening phase. By valorizing the waste, the overall efficiency of the process increased to 99.26%, which allowed for a 40% reduction in the total irreversibilities. Optimization of the stages with the highest unavoidable losses and better energy integration of the process are suggested to maximize its performance. Full article

Background: This study aims to investigate the biomechanical characteristics of orthodontic miniscrews manufactured for use in infrazygomatic crests. Methods: This study analyzed the Zygomatic Spider Screw (HDC, Thiene, Italy), considering four variables: length, insertion angle, insertion depth, support thickness. Twenty-two configurations were tested on 66 miniscrews, all with a diameter of 2 mm, and were inserted into D1 bone-like supports. After compression tests, the deformation angles and linear distances between the tips of the miniscrews were measured. Results: Power analysis showed 99% power for the deformation angles and linear distance. The ICC indicated the good repeatability of the results, with values above 0.70. The mean maximum load values ranged from 21.5 N to 228.8 N, while the mean deformations ranged from 0.45 mm to 2.26 mm. Miniscrews with greater insertion depths (6 and 8 mm) exhibited approximately twice the average deformation (1.5 mm) compared to those inserted at 2 and 4 mm (0.71 mm). It was noted that miniscrews with higher deformation and a lower applied load were those with a working part length of 10 mm and an insertion depth of 2 mm, while those with lower deformation and a better load-bearing capacity were those with a working part length of 6 mm that were fully inserted into the bone support. Conclusions: The miniscrew design and insertion depth significantly affect biomechanical properties. It is advisable to maximize the insertion depth and minimize the distance between the support and the point of force application. The insertion angle did not prove to be a determining factor in the load. Full article

Seagrass ecosystems support complex biological interactions that shape marine community structure and ecosystem functioning. Thanks to their structural complexity, they support heterogeneous communities and interact with associated benthic invertebrates and fish populations, establishing complex relationships that influence the performance and fitness of the involved organisms. This study, through a systematic review, investigated the existing potential biotic interactions between seagrasses and epibionts–epiphytes on a global scale. We created a complex search string and ran it in the online databases Scopus and Web of Science, yielding a total of 62 final outcomes spanning from 1984 to 2024. Our results revealed both positive and negative effects of different biotic interactions among these habitat formers and their associated symbionts. The review showed that the most studied interactions referred to Posidonia oceanica (Delile, 1813) L. and Zostera marina (Linnaeus, 1753), which provide refuge and habitat to different epiphytes and epibionts. The reviewed studies highlighted the importance of epiphytes, their potential role in seagrass growth, nutrient dynamics, and their implications for light absorption, while epibionts enhance canopy structure and can protect seagrasses from predation, but potential drawbacks remain poorly understood. Understanding and preserving these intricate biotic interactions is critical to ensuring the long-term functionality and resilience of seagrass ecosystems in a continuously changing environment.

The Wnt signalling pathway plays a crucial role in tissue homeostasis and cancer biology due to its regulation of cellular processes, including proliferation, migration, and stem cell activity. Frizzled receptor 7 (FZD7) (a member of the F-class G protein-coupled receptors) has emerged as a key Wnt receptor within this pathway, which is elevated in several human malignancies. FZD7 is notably upregulated in gastrointestinal, breast, pancreatic, and hepatocellular carcinomas and transmits oncogenic Wnt signalling through canonical and non-canonical pathways. FZD7 promotes tumour initiation, and emerging evidence implicates FZD7 in cancer stem cell maintenance and epithelial–mesenchymal transition (EMT), reinforcing its role in metastasis. Therapeutic strategies targeting FZD7 have shown promise, including FZD7-specific monoclonal antibody-drug conjugates (ADCs), human single-chain fragment variable (scFVs) antibodies, and nanoparticles. Notably, our recent development of FZD7-ADC has demonstrated tumour-selective cytotoxicity with reduced off-target effects, positioning FZD7 as an attractive therapeutic target. Additionally, nanoparticle-based drug delivery systems have enhanced the precision of existing chemotherapies by targeting FZD7-expressing tumour cells. Despite significant advances, clinical translation remains a challenge due to potential on-target toxicity and the complexity of tumour microenvironments. Future research should focus on optimising delivery systems, refining antibody specificity, and conducting comprehensive preclinical and clinical trials. This review will focus on novel discoveries regarding FZD7 in cancer and provide an update on our original review on this subject in 2016. Additionally, we present new figures generated by our group using the publicly available Pan-Cancer Atlas RNAseq datasets, highlighting FZD7 expression patterns in patient samples. This integrated approach aims to provide updated insights into the function of FZD7 during cancer and its growing status as an attractive target for therapy. In summary, FZD7 stands out as a promising molecular target in cancer therapy due to its selective overexpression in tumours, functional role in Wnt-driven oncogenesis, and potential for innovative therapeutic applications. This review underscores the critical need for the continued exploration of FZD7-targeted therapies to improve patient outcomes in cancer treatment. Full article

Individuals diagnosed with ADHD are at a heightened risk of antisocial behaviors, substance abuse, emotional distress, and diminished happiness. Identifying protective factors that reduce the likelihood of these functional impairments in ADHD is vital. Research has shown that a strong sense of coherence (SOC) can serve as a protective factor against various risks and health issues. Therefore, investigating the relationship between SOC and functioning among adults and adolescents with ADHD is essential. A study involving 468 participants aged 15–50 who had reported being diagnosed with ADHD was conducted and analyzed by structural equation modeling. Individuals who reported higher SOC levels also reported lower levels of functional impairment across all domains. This association remained fairly consistent across gender and age groups. The results suggest that SOC is associated with reduced functional impairments in individuals with ADHD. Recognizing this association can aid in identifying those at higher risk within the ADHD population. Further research is warranted to test the causal relationship between SOC and functional impairment and explore potential therapeutic approaches to bolster SOC in individuals with ADHD. Full article

This study evaluated the nephroprotective potential of dapagliflozin and silymarin, alone and in combination, against cisplatin-induced kidney damage in female Wistar rats. Cisplatin was administered at 3 mg/kg weekly to all groups except the normal controls, with treatments of silymarin (50 mg/kg/day), dapagliflozin (0.9 mg/kg/day), or both for 45 days. Dapagliflozin significantly reduced uric acid, the urea-to-creatinine ratio, and serum urea levels compared to nephrotoxic controls, while combination therapy showed further improvements. Both agents decreased inflammatory markers like TNF-alpha, IL-6, and IL-1 beta, with enhanced effects in combination. Oxidative stress markers, including nitrite and 4-HNE, were lowered, and antioxidant enzyme activities (catalase, SOD, and GSH-Px) were increased by dapagliflozin and silymarin, with the combined treatment yielding the most substantial improvements. Molecular analysis revealed elevated Nrf2 and HO-1 levels, which are critical for oxidative stress mitigation, particularly with combination therapy. Histologically, combination therapy preserved renal structure, closely resembling normal controls, while dapagliflozin and silymarin alone showed moderate inflammation and structural alterations. These findings highlight the effect of dapagliflozin and silymarin, especially in combination, to mitigate cisplatin-induced nephrotoxicity by reducing oxidative stress, inflammation, and apoptosis via modulation of the Nrf2/HO-1 pathway.

Background: Previous research has examined the acute effects of high-intensity exercise on muscle contractility, revealing potential interference in reaching peak contraction. This study aims to evaluate the impact of a standardized kettlebell swing protocol on low back musculature contractility, measured by tensiomyography (TMG), and pain sensitivity, measured by pressure algometry. Methods: Forty participants were randomly assigned to one of three groups: control, kettlebell swing, and kettlebell isometric hold. Pre-intervention TMG and pressure pain threshold (PPT) measurements were taken, followed by the intervention and post-intervention measurements. Results: Participants averaged 23.85 years (SD ± 2.73), 162.39 lbs (SD ± 28.69), and 174.29 cm (SD ± 12.45). Baseline ANOVAs showed no significant differences between groups for pre-intervention DM or PPT measurements, nor for demographics (p > 0.05). Although no significant within-group differences in TMG measurements were observed, the kettlebell swing group showed small mean differences in muscle displacement and contraction time for the gluteus maximus with effect sizes ranging from 0.09 to 0.49. Conclusions: The study suggests posterior chain muscles, such as the gluteus maximus, are involved in kettlebell swings. Also, despite the lack of significant TMG differences within groups, the kettlebell swing group exhibited small changes in muscle characteristics, enhancing the understanding of exercise-induced hypoalgesia and posterior chain involvement in resistance exercises.

Agriculture is an anthropic activity with a significant impact on the environment and biodiversity. Hence, the conservation and proper management of wildlife inhabiting agricultural areas is crucial to ensure both food production sustainability and biodiversity preservation. The presence and distribution of the Eurasian Blackcap (Sylvia atricapilla) was evaluated in different crops during winter and the influence of vegetation structure and altitude on its abundance was analyzed. It was hypothesized that the presence and abundance of the species would be influenced by vegetation structure and altitude. Sampling was conducted in 60 agricultural plots differentiating homogeneous and heterogeneous crops. Warblers were recorded by sight and hearing along 1 km transects. The effect of vegetation structure on the warbler abundance was analyzed by carrying out ANOVAs and Mann–Whitney tests. The Eurasian Blackcap was detected in 75% of the sampled plots. Significant differences in vegetation structure between occupied and unoccupied crops were not found; however, an effect of the altitude of the transects was observed, occupying mostly lower areas. The warbler abundance was not significantly affected by crop type nor sampling year. This study provides valuable information on the ecology and distribution of the Eurasian Blackcap in agricultural crops, enriching the knowledge on how to establish the sustainable management of croplands and ensure the conservation and proper management of the species in agricultural areas.

Fluorescent cholesterol probes are indispensable tools for studying membrane structure, dynamics, and trafficking. To better understand the structure–function relationship of fluorescent cholesteryl probes, we developed a series of five new modular naphthalimide-containing cholesteryl probes (CND15–CND19). These probes incorporate an L-lysine linker between the cholesterol moiety and the fluorophore, along with a series of distinct head groups. We conducted extensive biophysical characterizations of these probes, including the determination of their solvatochromic properties and lipid partitioning behavior using giant unilamellar vesicles. Molecular dynamics simulations were employed to identify key molecular interactions of these probes within model lipid membranes. Furthermore, live-cell imaging in 3T3 fibroblasts demonstrated the potential applications of these analogs in live-cell imaging, measuring cellular membrane dynamics and studying cholesterol-related processes. The results of this study underscore the critical role of the linker and head group in designing fluorescent cholesterol-mimicking probes. These findings provide valuable insights into optimizing probe designs for future cholesterol and membrane biology research. Full article

The role of smoking in the development of periodontal disease has been well explored. However, this study aims to explore the relationship between intensity of smoking history and permanent tooth removal. We utilized the 2022 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative sample of 107,859 US adults, to explore this association. Smoking history intensity was a BRFSS-derived measure of pack-year smoking history. Permanent tooth removal was binarized as the presence or absence of a history of permanent tooth removal. A binary logistic regression was conducted to analyze this association after adjusting for a variety of sociodemographic, health, and substance-use covariates. There was a dose-dependent relationship in which increasing smoking history intensity was associated with increased odds for removal of one or more permanent teeth. For example, those who reported a pack-year history of 30 or more years had a 6.4 times significantly higher odds of reporting a history of permanent tooth removal when compared to those with a 0 pack-year history (adjusted odds ratio = 6.37, 95% CI = 3.80–10.69, p < 0.001). These findings can be used to promote smoking reduction or cessation as a means of decreasing risk of permanent tooth removal due to tooth decay or gum disease. Full article

Action Quality Assessment (AQA)—the task of evaluating how well human actions are performed—is essential in domains such as sports and medicine. Existing AQA methods typically rely on score regression following feature extraction but often neglect the ambiguity inherent in extracted features. In this work, we introduce a novel AQA framework that incorporates a modified attention module to better capture relevant information. Our approach segments video data into clips, extracts features using the I3D network, and applies attention mechanisms to highlight salient features while suppressing irrelevant ones. To assess feature quality, we employ score distribution regression and propose an uncertainty-aware score distribution learning strategy that models features as Gaussian distributions. We further leverage Variational Autoencoders (VAEs) to capture complex latent representations and quantify uncertainty. Extensive experiments on the MTL-AQA and JIGSAWS datasets demonstrate the effectiveness and robustness of our proposed method. Full article

This study investigates the influence of varying nitrogen-to-phosphorus (N:P) ratios on the growth, nutritional composition, and nutrient removal efficiency of Wolffia globosa under controlled laboratory conditions. Six treatments with N:P ratios of 1:3, 1:2, 1:1, 2:1, 3:1, and a control were evaluated. The findings indicate that a balanced N:P ratio (1:1) promotes optimal growth, resulting in the highest biomass yield and specific growth rate (SGR = 0.120 g/day). In contrast, a nitrogen-rich ratio (3:1) enhanced protein accumulation and phosphorus removal, while the 2:1 ratio favored nitrogen uptake. These results reflect underlying physiological responses, including nitrogen assimilation and phosphorus uptake mechanisms regulated by nutrient balance. A trade-off was observed between biomass production and phosphorus removal efficiency, suggesting that different N:P ratios may be suited to specific application goals. This study contributes to a more comprehensive understanding of how macronutrient balance affects growth and metabolism in W. globosa and offers practical implications for optimizing its use as both a sustainable protein source and a biological agent for nutrient remediation in wastewater treatment systems.

Recent advancements are synthesized to provide a clear roadmap for future research toward sustainable energy solutions. Full article

The Russian Black Pied (RBP) is one of Russia’s most popular dairy cattle breeds. It was developed in the USSR during the 1930s by crossing Russian native cattle with Dutch cattle. Since the mid-1970s, the RBP has been cross-bred with Holstein cattle to enhance milk production. To trace haplotypes and selection signatures in the RBP genomes formed during cross-breeding and selection, we conducted local ancestry inference and scans for selection signatures in 12 resequenced RBP animals. Scans for selection using hapFLK and window-based F_ST identified 65 putatively selected regions across the genome, with 4 identified by both methods. Candidate missense variants were detected within these regions, including KIAA1755, CNBD1, and MPZL3, which may be related to milk traits, pathogen resistance, and climate adaptation. Local ancestry inference and functional annotation analyses suggest that regions with a higher fraction of native haplotypes are enriched for genes associated with keratin filaments, antimicrobial defence, the immune system, protein digestion, and amino acid transporters. The results of our study could be utilised for conservation purposes and the improvement of this and other breeds. Full article

Due to limited fossil resources and climate change, biotechnological processes converting renewable resources into industrial raw materials are increasingly important. Many of these processes require yeast extract for microorganism growth, a high-cost factor. Therefore, the use of inexpensive, protein-rich agricultural raw materials as a source of nutrients is desirable. However, their usage usually results in lower product concentrations and productivity in the fermentation process. This work investigates the nutritional requirements for the production of L-lactic acid using Lactobacillus casei ATCC 393 and 1,3-propanediol using Clostridium butyricum DSM 25047, aiming to replace complex nutrient sources with hydrolyzed protein-rich agricultural raw materials. In the production of 1,3-propanediol, yeast extract was largely (80%) replaced by rapeseed meal hydrolyzate, achieving the same final product concentration and maximum productivity. In the production of L-lactic acid, rapeseed meal hydrolyzate supplemented with B vitamins, mineral salts, cysteine, and tryptophan replaced yeast and meat extracts, achieving the same final product concentration with comparable maximum productivity.

Radiotherapy is one of the major cancer treatments that uses controlled doses of ionizing radiation to damage tumor cells. The monitoring of charged particles within a medium is of tremendous importance in radiotherapy. Monte Carlo methods can be used to estimate radiation profiles; however, despite their effectiveness, they are computationally expensive, which limits their practicality. To simplify the analysis, approximate analytical methods focused on estimating the range of charged particles and their velocity function within a medium have been previously derived. Previous solutions include non-elementary functions, such as the exponential integral function with relativistic coordinate transformations, or the use of regular perturbation methods accounting for small relativistic effects. In this paper, a much simpler approach is presented to assist practitioners in the field of radiotherapy. Using the proposed method, the particles’ range and velocities are calculated exclusively with elementary functions. The main advantage of the proposed approach, aside from its straightforward application, is its suitability for relativistic velocities. The equations derived in this paper were successfully tested at the radiotherapy level, accommodating protons with energies of up to 350 MeV. Full article

The process of convergence and the aggregation of polyamide granules and clusters on a water surface has been studied. These granules are widely used to visualize flows on the surface and in the bulk of the water. It is shown that the law of particle motion during convergence corresponds to electrostatic interaction. Like other polymers, polyamide particles are easily charged owing to friction. The quantitative estimation of the surface charge of the granules gives values close to the results of other authors. The range of action of electrostatic forces is fractions of a millimeter, and the maximum velocities of the clusters and granules measured in the experiment do not exceed 1 mm/s when converging. Therefore, when studying flows, electrostatic interaction does not distort the velocity field if the concentration of the granules is low and the velocities of the flows are rather high.

Eye-gaze writing technology holds significant promise but faces several limitations. Existing eye-gaze-based systems often suffer from slow performance, particularly under challenging conditions such as low-light environments, user fatigue, or excessive head movement and blinking. These factors negatively impact the accuracy and reliability of eye-tracking technology, limiting the user’s ability to control the cursor or make selections. To address these challenges and enhance accessibility, we created a comprehensive dataset by integrating multiple publicly available datasets, including the Eyes Dataset, Dataset-Pupil, Pupil Detection Computer Vision Project, Pupils Computer Vision Project, and MPIIGaze dataset. This combined dataset provides diverse training data for eye images under various conditions, including open and closed eyes and diverse lighting environments. Using this dataset, we evaluated the performance of several computer vision algorithms across three key areas. For object detection, we implemented YOLOv8, SSD, and Faster R-CNN. For image segmentation, we employed DeepLab and U-Net. Finally, for self-supervised learning, we utilized the SimCLR algorithm. Our results indicate that the Haar classifier achieves the highest accuracy (0.85) with a model size of 97.358 KB, while YOLOv8 demonstrates competitive accuracy (0.83) alongside an exceptional processing speed and the smallest model size (6.083 KB), making it particularly suitable for cost-effective real-time eye-gaze applications.

This study investigated the impact of soil properties under greenhouse conditions on the growth and productivity of two chickpea (Cicer arietinum) genotypes (V1 and V2) using two distinct soils collected from Marchouch and Beni Mellal sites. Soil analysis revealed significant differences in organic matter, phosphorus, potassium, and nitrogen levels between the two sites. Marchouch soil, characterized by higher nutrient content, especially phosphorus, demonstrated a more favorable environment for chickpea growth, resulting in enhanced plant height, leaf number, chlorophyll content, seed number, and seed weight. Variety V2 showed slightly better performance than V1 across both soil types, particularly in terms of seed yield and mineral content. This research highlights the importance of soil nutrient availability. Furthermore, this study emphasizes the important role of phosphorus in chickpea growth, with Marchouch soil having a higher phosphorus level (62.9 mg kg⁻¹), significantly boosting plant development and yield. Although soil mineral characteristics and genotypes had little effect on most minerals, zinc (19.77 mg uL⁻¹) and iron (69.43 mg uL⁻¹) levels stood out as significant exceptions. Therefore, further studies should focus on examining additional soil characteristics and expanding genotype selection. Based on the findings, Marchouch soil appears to be more favorable for chickpea cultivation. However, more research is needed on the effect of soil and genotypes on Rhizobium activity. Full article

Estimating the amplitude of a sinewave from a set of data points is a common procedure in various applications. This is typically achieved using a least squares method that provides closed-form estimators. The sampling process itself is often affected by different non-ideal phenomena like additive noise, phase noise, or sampling jitter, for example. Here, the precision of the estimation of a sinewave amplitude when the samples are affected by phase noise or sampling jitter is studied in the case of coherent sampling. The mathematical expression derived is useful in obtaining the confidence intervals for the estimated sinusoidal amplitude. It is also valuable at the time of choosing the proper number of samples to acquire from a signal in order to reach a certain desired level of sinewave amplitude estimation precision. The analytical expression presented is validated using both numerically generated data and experimental data. Various non-ideal factors, such as a fixed, uncontrollable amount of jitter in the setup, additive noise, analog-to-digital converter non-linearity, and limited signal bandwidth, are observed and discussed. Additionally, this work presents an exhaustive overview of the technical aspects involved in the experimental validation, including the implementation of the Monte Carlo type procedure, instrument interface, programming language, and the general development of automated measurement systems, which may be useful to other engineers.

A study was conducted in a winery in Puglia on the effect of cooling crushed and destemmed Bombino Nero grapes, comparing two different systems: (1) traditional indirect heat exchange using a water-cooled with a tube-in-tube heat exchanger and (2) a direct refrigeration system with a CO₂ system. The must obtained from crushed grapes cooled with CO₂, compared to that treated with an exchanger, has a lower ethanol content, greater presence of sugars and higher color and tone; these qualitative advantages are due to much faster cooling and deoxygenation, which slowed down the development of indigenous yeasts present on the surface of the grapes and allowed for greater extraction of the anthocyanin components in the must. These qualitative advantages give added value to the wine, justifying higher energy costs. In fact, the test results highlighted limitations associated with higher energy costs for the direct cooling system with CO₂ compared to the traditional one with indirect heat exchange. Energy consumption in the winery is lower for the CO₂ system, but energy and costs for capture, liquefaction and stockage must also be considered. However, from an energy and functional point of view, the potential advantages related to the clarification phase should not be neglected: it could be carried out at higher temperatures than those currently adopted for musts treated with CO_2, limiting the amount of the required CO₂ and consequently the total energy consumption for the whole process.

PVC has become an indispensable material worldwide. However, its production method (suspension) presents significant sustainability challenges, such as negative environmental impacts and high operational costs due to energy consumption. For this reason, a combined analysis was conducted involving energy integration using Aspen Energy Analyzer™ V14 software and a technical process analysis. This methodology aims to reduce industrial utility consumption and assess the sustainability performance of this alternative. The integration through pinch analysis revealed that it is possible to reduce the energy consumption of the process by 29% in heating utilities and 6% in cooling utilities. The minimum utility requirements were 21 GJ/h for heating (down from 29 GJ/h) and 131 GJ/h for cooling (down from 139 GJ/h). This reduction resulted in approximately a 41% decrease in utility costs. Additionally, the reduction in burner energy consumption led to lower greenhouse gas emissions, with a decreased natural gas consumption of approximately 279 m³. However, only two streams could be integrated due to technical process limitations; therefore, it is recommended to explore integrations with complex operations such as reactors and phase-change processes. In addition to this, the WEP technical evaluation yielded promising results showing a decrease in the specific energy intensity by 3219.506 MJ/t (being 4681.8 MJ/t), which represents an economic saving in industrial services (energy purposes) of approximately USD 886.000 per year, satisfying the optimization of the process despite the limitations when integrating it energetically. Finally, a more in-depth analysis should be conducted to further integrate other streams of the process to reduce utilities consumption. Full article

This study presents the first instance of determining environmental uric acid in urban dust using high-performance anion exchange chromatography coupled with electrochemical detection. The optimum chromatographic conditions were identified as a 10 mm × 4.6 mm, 10 µm anion exchange column with a mobile phase of pH 8 50 mM phosphate buffer. Cyclic voltametric investigations over a pH range of 2 to 12 showed that uric acid gave a single diffusion-controlled peak. Hydrodynamic voltametric studies of uric acid using a mobile phase of 50 mM pH 8.0 phosphate buffer over the range 0.0 V to +1.4 V (vs. stainless steel) showed a similar single oxidation wave, which plateaued at potentials more positive than +0.7 V (vs. stainless steel). An applied potential of +0.90 V (vs. stainless steel) was chosen for further investigations, and a linear range of 0.10 to 100 mg/L was obtained, with a detection limit of 0.866 mg/L based on a signal-to-noise ratio of 3. Dust wipe samples were extracted in pH 8, 50 mM phosphate buffer with the aid of sonication. Recoveries of 99.6% (% CV = 4.52%) were achieved for the dust wipe fortified with 16.8 µg of uric acid. Nitrate, nitrite, chloride, acetate, and sulfate ions were found not to interfere. The dust wipe samples were found to have uric acid levels of between 32.6 µg/m² and 3.98 mg/m². Full article

Chronic diarrhoea is a frequent complaint in dogs. Abdominal ultrasonography is frequently utilised in cases of dogs with chronic diarrhoea. The prevalence of neoplasia in dogs with chronic diarrhoea for which ultrasonographic findings are not suggestive of neoplasia has not been reported. This study aimed to list the histologic diagnosis of endoscopic gastroduodenal biopsies in this specific population. The medical records of 115 dogs with chronic diarrhoea for which an abdominal ultrasound was not suggestive of a neoplastic process and had undergone endoscopic biopsies were reviewed. Cases were excluded if an abdominal ultrasound revealed a focal intestinal mass, loss of intestinal wall layering, or a mass lesion in another location. Dogs that had undergone previous treatment with immunosuppressants were also excluded. Histologic findings revealed neoplastic features in 3 out of 115 cases (2.6%) and non-neoplastic conditions in 112 cases (97.4%). In conclusion, the prevalence of neoplastic disease in this population was very low. This is valuable information when considering the diagnostic approach in patients which meet the population criteria and which would historically have had endoscopy and biopsy recommended with the main goal of excluding neoplasia but have moderate–high anaesthetic risk, limited access to endoscopy and/or when financial constraints are present (Figure 1).

The main objectives of this research are, firstly, to determine the state of Autism Spectrum Disorder (ASD) caregivers in objective and subjective burden, psychological distress, and resilience, and, secondly, to assess the role of resilience as a mediator variable that could buffer the effect of objective burden on perceived burden and psychological distress. The method is descriptive, cross-sectional with a sample of 250 family caregivers. Results show that levels of burden were high, with half of the sample presenting psychological distress, and that the resilience level was above that of the general population. Additionally, the relational pattern showed significant positive relationships between burden and psychological distress, but negative relationships between these variables and resilience. Finally, as expected, resilience has worked as a buffer, decreasing the effect of objective burden, measured as hours/day caring, on subjective burden and psychological distress. The direct impact of resilience on burden and psychological distress, two of the more important risk factors for the mental health of ASD caregivers, as highlighted in this study, points to the necessity of implementing intervention or training programs that help caregivers to cope with stressors associated with the daily tasks of caring, to enhance resilience and personal growth out of stressful situations.

Phytophthora capsici is a phytopathogen that affects postharvest bell peppers, as it causes rotting and decreases their commercial value. This study evaluates the efficacy of chitosan as a biocontrol agent against P. capsici on bell peppers using in vitro and in vivo assays. The antifungal activity of chitosan was evaluated at four concentrations (0.5, 1.0, 1.5, and 2.0 g L⁻¹). Its effect on mycelial growth inhibition, sporangial germination, disease incidence and severity, and fruit weight loss was determined. The results show that concentrations of 1.0 g L⁻¹ or higher completely inhibited P. capsici growth and sporangial germination in vitro and reduced disease incidence and severity to 0% in treated fruit. Furthermore, chitosan treatments preserved the fresh and dry weight of the fruit, which prevented postharvest deterioration. This study demonstrates that chitosan is an effective and environmentally friendly alternative for the management of postharvest diseases in bell peppers. This could reduce consumer dependence on synthetic fungicides and preserve fruit quality. Full article
