Although modern web technologies increasingly rely on high-performance rendering methods to support rich visual content across a range of devices and operating systems, the field remains significantly under-researched. The performance of animated visual elements is affected by numerous factors, including browsers, operating systems, GPU acceleration, scripting load, and device limitations. This study systematically evaluates animation performance across multiple platforms using a unified set of circle-based animations implemented with eight web-compatible technologies, including HTML, CSS, SVG, JavaScript, Canvas, and WebGL. Animations were evaluated under controlled feature combinations involving random motion, distance, colour variation, blending, and transformations, with object counts ranging from 10 to 10,000. Measurements were conducted on desktop operating systems (Windows, macOS, Linux) and mobile platforms (iOS, Android), using CPU utilisation, GPU memory usage, and frame rate (FPS) as key metrics. Results show that DOM-based approaches maintain stable performance at 100 animated objects but exhibit notable degradation by 500 objects. Canvas-based rendering extends usability to higher object counts, while WebGL demonstrates the most stable performance at large scales (5000–10,000 objects). These findings provide concrete guidance for selecting appropriate animation technologies based on scene complexity and target platform. Full article

Gastrointestinal parasites are a major health and economic concern in small ruminants. The classic microscopic approach using the manual McMaster method serves to quantitatively count parasite eggs, which are labor-intensive and prone to variation. Artificial intelligence-based systems (Parasight^®, powered by Fecalsight AI™) could provide quicker and more objective alternatives; therefore, independent validation is necessary before clinical implementation. The objective of this study was to evaluate the agreement, classification consistency, and diagnostic performance of Parasight^® relative to the manual McMaster method, with a focus on its suitability as a screening and decision-support tool. Fecal samples from 44 Kiko goats over 3 sampling times were analyzed using both methods, with manual counts performed independently by 2 observers. Agreement between methods was assessed using Lin’s concordance correlation coefficient, Bland–Altman analysis, and Cohen’s Kappa for categorical classification. Diagnostic performance for identifying animals exceeding the clinical treatment threshold (>1000 eggs per gram) was evaluated using receiver operating characteristic (ROC) analysis, and regression modeling was used to characterize associations between methods. Manual observers showed high reliability, confirming the suitability of the McMaster method as a reference. Compared with manual counts, Parasight^® consistently underestimated egg counts, resulting in poor-to-moderate absolute agreement; however, it reliably ranked animals by parasite burden and showed excellent discrimination for identifying animals above the treatment threshold (AUC = 0.90–0.96). Regression analyses further demonstrated linear or curvilinear associations depending on egg counts. Overall, the Parasight^® device reliably captured relative parasite burden but required a lower operational threshold to match manual treatment decisions. Full article

Although a yeast-based additive was initially employed as a performance enhancer, subsequent analysis revealed high aflatoxin B1 levels in the corn silage. Therefore, the objective of this study is to determine if the use of a yeast blend in the diet of Holstein calves that consumed feed naturally contaminated with high levels of aflatoxin can minimize the negative impacts of mycotoxins on animal health, contributing to improved performance. For this, we used 24 Holstein calves (6 months old) divided into two groups: Control (n = 12; no additive) and Treatment (n = 12; 5 g additive/animal/day). During the 100-day experiment, animals were weighed, feed intake was measured, blood samples were collected to assess health, and ruminal fluid was analyzed for ruminal fermentation. We observed greater weight gain and better feed efficiency in cattle that consumed the yeast-based additive compared to the control group. Yeast ingestion increased the concentration of propionic acid in the experimental environment, as well as increasing the protozoan count. Higher lymphocyte counts combined with higher levels of immunoglobulin G in the blood of females that consumed the additive were observed. Lower activity of enzymes that are biomarkers of liver damage, as well as markers of oxidative stress, was observed when animals consumed the yeast blend compared to the control group. Lower levels of ceruloplasmin (positive acute phase protein) and higher levels of transferrin (negative acute phase protein) are indicative of an anti-inflammatory response to the additive. The results preliminarily suggest that the consumption of the yeast blend is a nutritional tool capable of acting as a performance enhancer, even under challenging conditions, such as diets contaminated with aflatoxin at levels exceeding international limits.

Background: Dietary habits established during young adulthood have long-term implications for health, and food choices among university students are strongly shaped by contextual factors. Institutional eating environments represent a relevant setting for promoting healthier dietary behaviors, yet limited evidence integrates students’ engagement with these settings, their food consumption patterns across contexts, and the individual decision-making processes underlying food choice. Methods: This cross-sectional study analyzed survey data from 1519 students enrolled at a large Italian university. Measures included sociodemographic characteristics, self-identified dietary style, engagement with the university canteen, consumption frequency of selected food categories across institutional and non-institutional contexts, and category-specific food-choice motivations. Data were analyzed using descriptive analyses, Borda count rankings, paired comparisons, and multiple linear regression models. Results: Clear contextual differences in food consumption emerged across all food categories, with consistently lower consumption frequencies within the university canteen compared to outside settings (all p < 0.001). The largest contextual gap was observed for fruit consumption (d = 0.94), with similarly pronounced differences for plant-based foods. Taste was the most salient decision-making factor across food categories (overall M ≈ 4.4), while health-related motives were more prominent for healthier foods and gratification for desserts. Across contexts, self-identified dietary style was the most consistent predictor of food consumption, explaining substantial variance for animal-based protein consumption (R² = 0.293 in the canteen; R² = 0.353 outside), whereas age and gender showed smaller, food-specific associations. Conclusions: The findings highlight institutional eating settings as distinct food environments in which individual dietary preferences are only partially expressed. Effective strategies to promote healthier eating among university students should move beyond generic approaches and integrate interventions targeting service-related engagement, category-specific choice architecture, and students’ dietary identities.

Background: Hermetia illucens larvae provide a sustainable bioconversion pathway that transforms agro-industrial residues into protein- and nutrient-dense biomass and frass, suitable for animal feed and soil amendment, respectively. Nevertheless, the potential spread of antibiotic resistance (AR) genes and pathogenic microorganisms poses biosafety concerns. This study examined the impact of four residue-based diet formulations; peas and chickpea (D1), peas and wheat (D2), onion and wheat (D3), and wheat with digestate (D4), on microbial safety during the bioconversion process. Methods: Enterococcus spp. (viable counts), Salmonella spp. (presence/absence), and 13 AR genes associated with resistance to tetracyclines, macrolide-lincosamide-streptogramin B, β-lactams, vancomycin, and aminoglycosides were quantified in single substrates, diets, larvae, and frass using qPCR. Results: Principal component analysis revealed diet-driven AR gene profiles. D1 lowered the levels of the greatest number of tested AR genes, particularly erm(B), tetracycline, and β-lactam genes in frass, as well as tet(O) and vanB in mature larvae. In contrast, D2 increased the AR gene levels in frass. All diets except D4 eliminated Salmonella spp. Enterococcus spp. loads varied by diet and larval stage, with D2 reducing counts in frass. Conclusions: Diet composition directly shapes microbial dynamics and AR gene dissemination, indicating that legume-based substrates may enhance biosafety in bioconversion systems. Full article

Background: Pleurodesis is a treatment method that aims to create permanent adhesion between the pleural layers to prevent recurrent fluid or air accumulation in the pleural cavity. Talc, one of the most commonly preferred agents in this procedure, is widely used in clinical practice. In this study, a new talc formulation with a modified surface to impart antibacterial and analgesic properties was experimentally evaluated for the first time. The main objective of the study was to comparatively assess the inflammatory and fibrotic responses following standard talc and modified talc applications. Methods: Thirty-six 12-week-old female Wistar albino rats were simply randomly divided into three different groups: control (n = 12), standard talc (n = 12), and modified talc (n = 12). Under anesthesia, 1 mL of physiological saline containing 17 mg of talc was injected intrapleurally into the right hemithorax. The presence of pneumothorax after the procedure was assessed by chest radiography. After a 12-day follow-up period, the animals were euthanized. Bronchoalveolar lavage (BAL) fluid samples, blood samples, and lung and pleural tissue samples were collected for biochemical, histopathological, and immunohistochemical analyses. Results: Modified talc application resulted in a significant increase in both visceral and parietal pleural thickness (p < 0.05). Granulation tissue formation and collagen deposition were significantly higher in the modified talc group. In addition, TGF-β expression and CD68-positive macrophage count increased significantly in the modified talc group (p < 0.05). Inflammatory changes in the lung parenchyma were limited and not statistically significant. Conclusions: The modified talc formulation enriched with lidocaine and antibacterial agents produced a stronger inflammatory and fibrotic response compared to standard talc. These findings indicate that modified talc may increase the effectiveness of pleurodesis. Furthermore, the absence of significant lung parenchymal damage suggests that this treatment is locally effective and feasible. However, further long-term and advanced studies are needed to translate these results into clinical use. Full article

The present study aimed to evaluate whether the inclusion of curcumin as a performance enhancer in finishing cattle has positive effects on animal production, the ruminal environment, hematological and biochemical markers, as well as meat quality. Sixteen castrated Holstein steers, 8 months of age, with an average body weight of 247 ± 3.89 kg were divided into two groups: Control, consisting of animals that consumed 144 mg of monensin/animal/day (n = 8); Treatment, consisting of animals that consumed 552 mg of curcumin/animal/day (n = 8). Animals were fed a diet containing 44% roughage (corn silage) and 56% concentrate for 105 days. During this period, body weight measurements were recorded, and blood samples were collected for the determination of hematological, biochemical, and immunological variables. At the end of the experimental period, animals were slaughtered and meat samples were collected for evaluation. No differences were observed between groups for animal performance, feed intake, or feed efficiency. A lower leukocyte count (lymphocyte and granulocyte) and a higher platelet count were observed in animals that consumed curcumin. These animals also exhibited higher cholesterol levels, along with lower circulating glucose concentrations compared to the control group. In the ruminal environment, higher bacterial activity and greater protozoal counts were observed in the treatment group, but no effects on ruminal short-chain fatty acids were observed. Higher activity of the enzymes glutathione S-transferase in serum and superoxide dismutase in meat was observed, combined with lower lipid peroxidation in serum and meat. Meat from steers fed curcumin showed greater yellow color intensity, higher water-holding capacity, and a higher proportion of monounsaturated fatty acids compared to the control group. These results suggest that curcumin can be used as a performance enhancer, similar to monensin, when thinking about performance, but beyond that, curcumin triggered anti-inflammatory and antioxidant action.

Mastitis remains a prevalent and economically detrimental disease within the dairy industry, profoundly affecting animal welfare, milk quality, and overall production output. Nowadays, Somatic Cell Count (SCC) is widely recognized as the gold-standard indicator for the detection of mastitis; however, its limitations in pathogens discrimination and the lack of early-stage characterization of mastitis highlight the need for complementary diagnostic approaches. This review synthesizes recent research into the development and validation of novel biomarkers for the early and accurate identification of mastitis in dairy cows. The investigation encompasses a range of biological molecules for improving mastitis diagnosis. Biomarkers such as lactoferrin (LTF), β-defensin 4 (DEFB4), vitronectin, paraoxonase 1 (PON1), and N-acetyl-β-D-glucosaminidase (NAGase) show promise in distinguishing between cows not susceptible and cows susceptible to mastitis. Concurrently, nucleic acid-based biomarkers are emerging as a particularly promising frontier. While mitochondrial DNA (mtDNA) has demonstrated insufficient specificity, microRNAs (miRNAs) are gaining attention as highly stable and sensitive indicators of intramammary inflammation, potentially enabling the detection of subclinical infections before they become clinically apparent. Despite these advances, significant challenges related to specificity, reliability, and cost-effectiveness currently hinder the widespread practical application of any single biomarker. Therefore, future research should be directed towards the validation of a synergistic panel of multiple biomarkers to improve mastitis management in dairy cow farms. Full article

Background/Objectives: Platelet-rich plasma (PRP) is increasingly used in musculoskeletal medicine. Variability in PRP composition, driven by preparation- and donor-related factors, is considered a major contributor to inconsistent clinical outcomes. This study investigated whether habitual dietary patterns are associated with the cellular and molecular composition of leukocyte-poor PRP (LP-PRP). Methods: In this cross-sectional study, 75 healthy adults (25 vegans, 25 vegetarians, and 25 omnivores) who adhered to their dietary patterns for ≥6 months were enrolled. LP-PRP was prepared by a standardized protocol. Cell profiles were quantified in whole blood and LP-PRP; LP-PRP proteins (IL-6, IGF-1, HGF, and PDGF-BB) were measured by ELISA. Group differences, correlations, and multivariable regressions were performed. Results: Whole blood differed by diet with respect to total leukocytes, lymphocytes, and basophils, while platelet and erythrocyte counts did not. In LP-PRP, platelet enrichment ratios and leukocyte counts were comparable across diets. IL-6 in LP-PRP was lower in vegans vs. omnivores (p = 0.017); the Animal-Based Diet Score correlated positively with LP-PRP IL-6 and remained independently associated in regression (β = 0.35, p = 0.004). While IGF-1, HGF, and PDGF-BB did not differ between dietary groups, intake-based analyses revealed associations between specific dietary components and LP-PRP proteins; notably, the fruit and vegetable intake correlated inversely with PDGF-BB, and platelet–growth factor coupling was most pronounced among omnivores. Conclusions: Dietary patterns were associated with selected molecular components of LP-PRP—most consistently IL-6—while cell counts remain largely unchanged. However, interventional studies are needed to establish causality and determine whether dietary modification can influence clinical outcomes. Full article

In modern animal production systems, the use of alternative feed sources is essential for reducing production costs, protecting natural resources, and improving meat quality. This study evaluated the impact of a unique silage—one produced by agro-industrial by-products—on the growth, meat quality, and health parameters of finishing pigs. Eighteen pigs (120 days old, 59.47 ± 0.85 kg) were randomly assigned to three dietary treatments containing 0% (A), 5% (B), or 10% (C) silage. After 60 days, blood samples were collected for hematological and biochemical analyses; this was followed by slaughter for the collection of muscle tissues (triceps brachii, external abdominal oblique) and intestinal digesta (ileum, cecum). Final body weight did not differ among groups (124.54 ± 1.51 kg), and meat composition (fat, protein, collagen, and ash) and pH were unaffected (p > 0.05). ALT levels were significantly lower in group C than in A (p = 0.030). In the ileum, Enterobacteriaceae and Enterococci populations decreased, whereas Lactobacilli increased in B and C (p ≤ 0.05). Cecal Enterococci were reduced in both B and C (p ≤ 0.01), with a tendency for increased Lactobacilli in B. Group C showed higher total phenolic content (p ≤ 0.05) and an improved ω-6/ω-3 ratio (15.09 vs. 17.54 in A). The TBARS values did not differ among treatments. Campylobacter jejuni counts were lower in treatment C, and no Salmonella or Listeria monocytogenes were detected in any samples. The meat color of the triceps brachii was redder in treatments B and C (p = 0.001). Overall, the innovative silage increased phenolic content, supported improvements in gut microbiota, and maintained meat quality, indicating its potential as a sustainable feed ingredient.

Background/Objectives: Non-thermal atmospheric plasma (NTAP) has recently gained attention as a promising tool for tissue regeneration due to its ability to modulate cellular signaling and enhance wound repair. However, its effects on oral mucosal healing and associated molecular pathways remain insufficiently characterized. This study aimed to investigate the histological and immunohistochemical effects of NTAP on palatal wound healing in rats and to evaluate key biomarkers involved in angiogenesis, proliferation, and extracellular matrix remodeling. Methods: Sixty rats were randomly assigned to three groups: Saline Control Group (SCG), Chlorhexidine Gluconate Group (CHG), and NTAP-Treated Group (NTAPG). Standardized full-thickness excisional wounds were created in the central palatal mucosa. Animals were sacrificed on postoperative days 7, 14, and 21. Histological assessments included vascularization, inflammatory cell infiltration, collagen fiber organization, and epithelial gap measurements. Immunohistochemical analyses were performed using antibodies targeting VEGF-A, TGF-β, FGF-2, CD34, α-SMA, and Ki67 to evaluate angiogenesis, fibroblast activity, and cellular proliferation. Results: NTAP treatment significantly elevated TGF-β levels at all time points and increased α-SMA-positive cell counts on days 7 and 14. FGF-2 expression was the highest in NTAPG, while VEGF-A and CD34 levels were significantly elevated, indicating robust angiogenic activity. NTAP also reduced inflammatory cell infiltration relative to the other groups. NTAPG exhibited enhanced fibroblast proliferation, increased collagen deposition, improved vascularization, and accelerated re-epithelialization compared with SCG and CHG. Conclusions: NTAP significantly promoted palatal wound healing by enhancing proliferative activity, stimulating growth factor expression, and accelerating tissue repair. These findings suggest that NTAP may serve as an effective therapeutic approach for improving oral mucosal wound healing. Full article

Gastrointestinal nematodes are among the most significant parasites affecting livestock health and productivity, leading to major economic losses and contributing to the global increase in resistance to anthelmintics. Biological control using fungi with ovicidal and nematophagous activity offers an environmentally friendly alternative. This trial represents the first long-term field evaluation in cattle of the commercial combination of D. flagrans and P. chlamydosporia under natural infection conditions. Eighteen Holstein × Zebu males (12–15 months old) were divided into three groups (n = 6): T1 (D. flagrans), T2 (D. flagrans + P. chlamydosporia), and control. Treatments were administered orally daily (6 g/100 kg BW of each fungus; 10⁶ chlamydospores/g) for nine months. Fecal egg counts (EPG) and infective larvae in pasture (L3) were monitored. Groups T1 and T2 showed significantly lower EPG values than the control during most of the experimental period. Haemonchus spp. was identified as the predominant nematode, supporting its epidemiological relevance. The combined fungal treatment exhibited enhanced effectiveness, enhancing parasite suppression through complementary ovicidal and larvicidal mechanisms. This approach offers a sustainable alternative to the excessive use of chemical compounds and has the potential to contribute to integrated animal health and livestock production. Full article

Peripheral nerve repair remains a major clinical challenge, and novel strategies such as conduit-assisted repair have been developed to improve outcomes. In this study, we fabricated a 3D-printed nerve guidance conduit (NGC) composed of polycaprolactone (PCL), a biocompatible and biodegradable polymer, combined with acellular dermal matrix (ADM) derived from porcine dermis, in order to create a multilayered PCL–ADM NGC with both favorable mechanical properties and biological activity. Twenty rabbits were divided into four groups: a negative control group, a silicone tube repair group, an autologous nerve graft group, and a group treated with the 3D-printed PCL–ADM NGCs. Sciatic nerve regeneration was assessed at 4 and 12 weeks postoperatively using electrophysiological measurements, histological staining, and electron microscopy. The PCL–ADM NGC demonstrated comparable axonal regeneration and functional recovery to autologous grafting, and it significantly outperformed silicone tubes in terms of axonal count and maximal electrophysiological response. Histological and ultrastructural analyses further confirmed that the PCL–ADM NGC facilitated organized regeneration with dense myelinated axons and reduced degenerative changes. The fabricated NGCs exhibited excellent flexibility without compromising lumen diameter, which is critical for adapting to the physiological environment of peripheral nerves. These findings indicate that combining synthetic polymers with biologically derived matrices can enhance the regenerative microenvironment and overcome limitations of traditional synthetic conduits. In conclusion, the 3D-printed PCL–ADM NGC represents a promising alternative to both silicone tube repair and autologous nerve grafting by providing structural support and bioactivity while reducing the need for donor nerve harvesting. Further studies in larger animal models and longer follow-up periods will be required to confirm long-term efficacy and support clinical translation of this technology. Full article

Metronidazole (MTZ), a widely used antiamoebic and antibacterial drug, has been linked to male reproductive damage. The aim of this study was to investigate Olea europaea L. and Equisetum arvense L. ethanol extracts for the protection against testicular toxicity and male infertility caused by MTZ, and to characterize the underlying mechanisms. Forty-two male rats were divided into six groups. The animals in group 1 served as the controls and received a daily oral dose (1 mL) of the vehicle. The animals in group 2 received metronidazole at doses of 400 mg/kg. Group 3 was treated with E. arvense extract at doses of 100 mg/kg. Group 4 was treated with O. europaea leaf extract at doses of 400 mg/kg. Group 5 was treated with metronidazole and E. arvense extract at doses of 400 and 100 mg/kg, respectively. Group 6 was treated with metronidazole with O. europaea leaf extract at doses of 400 and 400 mg/kg, respectively. The rats were given a daily oral dose of different treatments for 60 days, after which the animals were euthanized to study the histopathological and molecular changes in the testis and the sperm count in the epididymis. The testosterone levels, MDA levels, and GSH contents were also assessed in the rats in all groups. The findings revealed that the MTZ treatment caused a substantial increase in MDA levels and upregulated the NBN gene expression relative to the control. Moreover, the MTZ treatment produced significant reductions in the sperm count and viability, testosterone levels, and GSH content, and downregulated the INSL-3, STAR, HSD-3β, and CYP11A1 gene expression compared to the control. The adverse effects in testicular tissue were significantly reduced in rats given the O. europaea leaves and E. arvense treatment. The findings may show that MTZ can enhance testicular toxicity and infertility, but both plant extracts can prevent these harmful consequences. Full article

Pomegranate peel, a rich agro-industrial by-product, contains abundant phenolic compounds with strong antioxidant and antimicrobial properties. However, the low stability and bioavailability of these compounds limit their efficacy in animal nutrition. This study investigated the effects of pomegranate peel phenolic extract (PE), either in raw form (PE300) or nano-encapsulated using gum–gelatin nano-capsules (NPE300), on health and growth parameters in newly weaned rabbits. Fifty-four male rabbits (40 days old) were assigned to three treatment groups: PE0 (control), PE300 (300 mg PE/L drinking water), and NPE300 (300 mg nano-encapsulated PE/L drinking water). Over six weeks, growth performance, hematological and immunological profiles, antioxidant status, microbial populations, and carcass traits were evaluated. NPE300 treatment demonstrated superior antimicrobial activity in vitro, with larger inhibition zones against all tested pathogens compared to PE300. In vivo, NPE300 significantly improved body weight gain (945.8 g) and feed efficiency, while also enhancing immune function, evidenced by higher white and red blood cell counts, phagocytic activity, and increased plasma IgG and IgM levels. Antioxidant markers showed that NPE300 significantly reduced malondialdehyde levels and tended to improve total antioxidant capacity. Furthermore, intestinal Clostridia counts were reduced, and beneficial microflora significantly increased in the NPE300 group. Carcass weight with edible parts, fur weight, kidney weight, and cecum length were also elevated under NPE300 treatment. In conclusion, nanoencapsulation of PE using gum–gelatin carriers enhanced its bio-efficacy, supporting better redox balance, immunity, gut health, and growth performance in rabbits. These findings support the application of nano-encapsulated PE as a promising natural growth promoter in rabbit production. Full article
