The machinability of wood is an insufficiently researched problem that is mainly related to the machinability of metals. The machinability of a material is a technological property that expresses the ability to remove the maximum amount of crisps from the machined surface in the shortest possible time with satisfactory machining quality and the lowest possible cutting forces and tool wear. The quality and efficiency of the production process when milling solid wood is influenced by the following factors: type of wood, density and moisture content of the wood, temperatures and dimensions of the workpiece as well as the hardness and strength of the wood. The parameters of the milling mode, such as the main and auxiliary motion, the cutting force and power and the power of the drive unit, have a direct effect on the milling process and are related to the milling tool, i.e. the type and quality of the material from which it is made, the number of cutting edges, the geometry of the cutting edge and the sharpness of the tool. In this work, the influence of significant input parameters on the machinability of solid wood in flat peripheral milling is analysed as a function of the cutting force as an output parameter by planning an experiment. The experimental results are mathematically modelled with the aim of obtaining a mathematical model of the process of large-scale milling of solid wood, i.e. its parameters as a function of the cutting force. The results of the experimental part and the results of the models are analysed and compared in order to draw appropriate conclusions and
BACKGROUND Community pharmacists' roles are expanding beyond traditional tasks to include digital health interventions. Despite the growing integration of digital health technologies, gaps remain in understanding pharmacists' digital health technology literacy (DHTL). Adequate DHTL is essential for supporting patients and ensuring the effective implementation of digital tools in pharmacy practice. OBJECTIVES To assess general digital literacy (gDL) and identify specific levels of DHTL among community pharmacists. METHODS A version of the DHTL Assessment Questionnaire (DHTL-AQ), specifically validated for use by community pharmacists, was distributed via online and paper-based formats. In addition to the DHTL-AQ, the questionnaire also included supplementary items assessing gDL. The sample size was calculated on the basis of the targeted pharmacist population. The data were analysed via SPSS. ROC curves were used to determine cut-off scores, whereas chi-square and Kruskal-Wallis tests were used to assess group differences and associations. RESULTS A total of 368 valid responses were collected. Among the respondents, 15.2% had low, 68.8% had medium, and 16.0% had high gDL. On the basis of these findings, DHTL cut-off scores were defined as low (35.9%), medium (19.6%), and high (44.5%). Significant differences in DHTL levels were associated with years of working experience. While 41.3% did not use social media professionally, Facebook, YouTube, Instagram, and Viber were the most commonly used platforms among pharmacists. CONCLUSION This study provides the first comprehensive assessment of DHTL among Serbian community pharmacists, revealing high general digital literacy but highlighting the need for targeted DHTL training. Future research should focus on expanding the sample size and addressing specific DHTL gaps. The approach used in this study offers a practical framework for assessing DHTL that can be applied internationally to inform the development of relevant, tailored training programs and support the expansion of pharmacist-led services in an increasingly digital health environment.
Background and objectives: Melanocytic nevi are among the most common skin lesions, yet their relationship with the peripheral nervous system has remained understudied. Given the neural crest origin of melanocytes and Schwann cells, and the neurotrophic signaling capabilities of pigment cells, this study aimed to investigate the density of nerve fibers within nevi and assess how it varies with respect to histological subtype and anatomical location. Materials and Methods: A total of 90 nevi were analyzed, including junctional, compound, and intradermal types, distributed across the head, trunk, and limbs. Immunofluorescence staining for the pan-neuronal marker PGP 9.5 and for CGRP were performed and nerve fiber density was quantified. Statistical evaluation using two-way ANOVA revealed that both nevus type and anatomical site significantly influenced the degree of total innervation. Results: Junctional nevi demonstrated the highest total nerve fiber density, significantly exceeding that of compound and intradermal nevi. Likewise, nevi located on the head exhibited a significantly greater density of PGP 9.5-positive nerve fibers compared to those on the trunk and limbs. No significant correlation was observed between nevus type and location, suggesting that both factors contribute independently to the differences in innervation. CGRP-positive innervation was uniform regardless of the histological type of nevus and anatomical location. Conclusions: These findings likely reflect the facts that junctional nevi reside at the dermo-epidermal junction, where nerve fibers are most abundant, while the skin of the head and neck is well known to be more richly innervated than other regions. In contrast, analysis of CGRP-positive fibers suggests that the heterogeneity detected with PGP 9.5 is primarily driven by other neuronal populations. The results support the hypothesis of a dynamic relationship between nevi and the peripheral nervous system, potentially mediated by neurotrophic factors. Understanding this interaction may provide insight into nevus biology, sensory symptoms reported in some lesions, and the evolving role of nerves in the tumor microenvironment.
In this paper, the drainage of storm water from traffic roads is analysed by analysing the traditional method of drainage using a separate sewage system, and also by analysing the integral approach to the drainage of rainwater in the urban area. The research objectives for the treatment of the topic in this paper are set and processed for the needs of planning and development of the sewage system for the drainage of rainwater from roads in urban areas, as well as for the evaluation and ranking of conceptual solutions and the elaboration of plans for the general solution for the collection and drainage of surface water from roads. For relevant rain episodes, i.e. rainfall of appropriate duration and intensity, runoff coefficients and flows were considered and analysed according to the rational method, all for the purpose of obtaining data on the amount of rainwater entering the sewage system. According to the set research program, it was necessary to work on defining and establishing the amount of precipitation for the area that was the research polygon, and based on exact measurement data, the optimal transverse and longitudinal drops of the level of the road were determined in order to drain rainwater from the roads as efficiently and quickly as possible, within the framework of the rules that define this area.
Sustainable nutrient management is critical for maintaining soil fertility, improving agricultural productivity and mitigating environmental impacts. This study evaluated the impact of Ireland's Nitrates Action Programme (NAP) on soil pH, phosphorus (P) and potassium (K) dynamics over a 12‐year period across four meso‐scale agricultural catchments. Using a spatially defined field‐scale sampling approach, trends in studied chemical soil parameters were assessed in response to changing agricultural practices and policy interventions. Results indicate a notable increase in optimal soil pH levels (21%), likely as a result of recent targeted advisory efforts. While overall median soil test P (STP) levels decreased by 0.5 mg/L, variability among catchments was evident, with one catchment showing a significant increase due to intensive poultry manure applications. Additionally, the proportion of P Index 1 soils increased by 9%, suggesting uneven P distribution and highlighting challenges in on‐farm nutrient management. Median soil test K (STK) increased by 17.6 mg/L, with notable gains in tillage and dairy enterprises, indicating shifts in nutrient application strategies. The study also identifies critical source areas (CSAs) of P losses, which decreased by 2%, aligning with NAP objectives. However, nearly 80% of soils remain of suboptimal fertility, particularly for P and pH, underscoring the need for targeted advisory efforts, improved nutrient planning and region‐specific management strategies. Findings provide key insights into how regulatory measures influence soil nutrient trends, informing future policies for sustainable nutrient management and environmental protection in Irish agriculture.
Introduction: Vitamin D (VD) deficiency has become a global epidemic in the past 2 decades. Cardiac troponin is a specific biomarker for detecting myocardial injury, particularly in the context of myocardial infarction (MI), where elevated levels are indicative of myocardial necrosis. This study aimed to investigate the relationship between VD levels and troponin values in patients admitted to the Intensive Care Unit under suspicion of acute coronary syndrome, including comparisons with patients ultimately not diagnosed with ACS. Materials and Methods: This cross-sectional study included a group of 69 patients who were hospitalized in the Intensive Care Unit of the Hospital under suspicion of acute coronary syndrome. The control consisted of patients without ACS. The content of VD-(25[OH]D) in blood plasma was measured by enzyme-linked immunosorbent assay during June–August 2024. Blood samples were taken in tubes with ethylenediaminetetraacetic acid anticoagulant. The tubes without anticoagulant were used for collecting blood for VD, fibrinogen, D-dimer, and lipid parameter measurement. Results: A statistically significant difference in total cholesterol levels was observed between patients with angina pectoris and those with MI (P < 0.05). Pearson correlation analysis also demonstrated a moderate negative correlation between VD levels and troponin values in patients diagnosed with MI (P < 0.05), indicating that lower VD concentrations may be associated with greater myocardial injury. Conclusions: Based on the data obtained, the medical community is inclined to believe that correction of VD deficiency has great prognostic significance. Further clinical and experimental studies are needed to study in more detail the mechanisms of the negative effects of VD deficiency on the cardiovascular system.

Background: Neoadjuvant endocrine therapy (NET) is widely used for ER⁺/HER2-negative breast cancer as it reduces tumor burden and modulates the tumor microenvironment. However, its effects on key immune cell populations remain unclear. Methods: In this retrospective study, pre- and post-treatment samples from 44 ER⁺/HER2-negative breast cancer patients treated at Antwerp University Hospital and Duke University(2006-2018) were analyzed by immunohistochemistry. We quantified stromal tumor-infiltrating lymphocytes (sTILs) along with markers for T cells, regulatory T cells (including the FOXP3/CD4 ratio), and macrophages (CD68), as well as immune checkpoint markers (PD-L1, PD-1, CTLA-4, TIM-3, and LAG-3). Treatment response was evaluated by changes in tumor size, Ki-67, and the Residual Cancer Burden (RCB) index. Results: NET significantly reduced tumor size (median decrease: 4.5 mm; p < 0.001) and Ki-67 levels (median reduction: 9%; p < 0.001) while sTIL levels remained stable (median: 5%; p = 0.08). CD4⁺ T-cell infiltration increased significantly post-treatment (p = 0.03). CD8⁺ T cells exhibited a heterogeneous response with a significant negative correlation between CD8⁺ counts and tumor size (Spearman r = -0.45, p = 0.003) indicating that higher CD8⁺ infiltration is associated with smaller tumors. FOXP3⁺ T-cell counts decreased from a median of 22.5% to 15% (p = 0.14) and the FOXP3/CD4 ratio declined significantly from a median of 2.307 to 1 (p = 0.04) suggesting a shift toward a less immunosuppressive tumor microenvironment. Higher pre-treatment CD68 expression correlated significantly with improved tumor NET response (p = 0.03). Immune checkpoint analysis revealed non-significant trends toward increased expression of PD-L1 (9% to 25%; p = 0.088), PD-1 (18% to 34%; p = 0.16), and LAG-3 (43% to 66%; p = 0.22) while CTLA-4 (23% to 27%; p = 0.69) and TIM-3 (64% to 52%; p = 0.53) remained largely unchanged. Conclusion: NET elicits profound alterations in the tumor microenvironment of ER⁺/HER2-negative breast cancer. The therapy reduces tumor proliferation and reconfigures immune cell dynamics, as evidenced by increased CD4⁺ T-cell infiltration, a beneficial reduction in the FOXP3/CD4 ratio, and a heterogeneous response of CD8⁺ T cells where higher CD8⁺ levels are linked to smaller tumors. In addition, elevated pre-treatment macrophage levels are predictive of improved tumor NET response. These results underscore the potential of integrating immune parameters as predictive biomarkers for NET efficacy and support further exploration of combined treatment strategies, including the use of immune checkpoint inhibitors, to optimize patient outcomes.Department of Defense Breast Cancer Breakthrough level 2 Award W81XWH2010153 (G.R.D.)

Pathological response is a surrogate marker of efficacy of neoadjuvant therapy in various tumour types, but there is no consensus on reporting pathological response for renal cell carcinoma. We aimed to assess the status of pathological response reporting in renal cell carcinoma and develop a recommendation on tissue preparation and response reporting for neoadjuvant treatment. We conducted a systematic review of publications on the PubMed and Web of Science databases to identify manuscripts reporting response to pre-surgical therapy in renal cell carcinoma. 119 eligible papers were identified. Only five (4%) studies included details of how pathological response had been assessed. Qualitative statements on residual tumour were common (55 [46%] studies), but only eight (7%) studies used a quantitative assessment of pathological response. Guidelines for tissue preparation and pathological response reporting were reviewed at an international workshop held at the Netherlands Cancer Institute in October, 2024, and further developed through expert discussions. To assess neoadjuvant pathological response, nephrectomy specimens should be sampled with the use of a standardised baseline approach with consideration for more extensive sampling. Microscopic assessment should quantify the residual viable tumour in 10% intervals and greatest linear extent. Clinical details, including the neoadjuvant therapy received, should accompany the pathological assessment. In this systematic review, we describe a standardised method for assessment and reporting pathological response, initially intended for use in clinical trials or research settings. These guidelines will help investigators to assess whether the degree of pathological response is linked to survival outcomes and will inform future standard reporting practices.
INTRODUCTION Carotid endarterectomy (CEA) remains the gold-standard treatment for high-grade carotid artery stenosis. While patch angioplasty reduces perioperative complications and restenosis risk compared to primary closure, the optimal patch material remains debated. This study evaluates the long-term safety and effectiveness of CEA with Dacron patch closure regarding overall survival, stroke prevention, and restenosis rates. METHODS A retrospective analysis was performed on 200 patients who met inclusion criteria of either symptomatic carotid stenosis of any degree according to the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria, or asymptomatic stenosis with a NASCET grade ≥70%. All patients underwent carotid endarterectomy (CEA) with standardized Dacron patch closure. Symptomatic stenosis was defined as ipsilateral transient ischemic attack or stroke within six months preoperatively. Perioperative data, survival, stroke-free survival, and freedom from restenosis (≥70% restenosis) were assessed through structured clinical follow-up and serial duplex ultrasound over 5 years. Kaplan-Meier estimates and subgroup analyses were performed according to symptomatic status, baseline stenosis severity, and sex. Log-Rank and / or Wilcoxon Tests were applied to analyze differences between the subgroups. RESULTS Among 200 patients, 26 adverse events (12.9%) were observed, with bleeding events exclusively associated with significantly prolonged clamping times (p = 0.0221 and twice p < 0.0001). Most complications (8.0%) occurred during follow-up, and no deaths were linked to stroke or restenosis At 5 years, overall survival was 93.7%, freedom from stroke was 97.6%, and freedom from restenosis was 97.5%. Symptomatic patients showed slightly lower survival (91.8% vs. 95.7%) and stroke-free survival (96.2% vs. 99.0%) compared to asymptomatic patients, reflecting higher baseline vascular risk. No significant differences in outcome were observed across different NASCET stenosis subgroups. However, a significant sex difference was found in restenosis rates: 5-year freedom from restenosis was lower in women (88.4%) than in men (98.0%; p = 0.017). Stroke rates remained low and similar between sexes. CONCLUSION CEA with Dacron patch closure provides durable long-term stroke protection and patency, with perioperative and late complication rates at the lower end of reported ranges. All bleeding events linked to significantly prolonged clamping times, suggesting intraoperative clamping duration may serve as an early indicator for postoperative bleeding risk. Our data advocate for a potentially increased risk of restenosis in females, which may warrant heightened vigilance and closer duplex ultrasound surveillance during follow-up. These results of this study support the continued use of Dacron patches as a safe and effective option for carotid reconstruction.
Background: All generations of living beings have been and will be exposed to ionizing radiation. Until the discovery of radioactivity, man was not aware that ionizing radiation was a part of him and his environment. Humans are mainly exposed to gamma and beta radiation from terrestrial radionuclides, which represent the main source of irradiation of the human body. Materials and Methods: This paper presents the research overview of the dose rates of gamma and beta radiation, measured outdoors in the research locations by the Gamma–Scout device. The measurements were performed at fifteen locations in the area of Tuzla Canton, Bosnia and Herzegovina. The Gamma–Scout device was mounted outside on the table, at a height of 50 cm above ground in the vicinity of residential buildings in periods of 30 minutes. Results: The results presented include gamma, gamma+beta, and beta dose rate measurements. Based on these results, the annual effective doses originating from gamma and beta radiation were estimated. Results of measurements taken by this method showed that the values of the annual effective dose of gamma and gamma+beta radiation were in the interval of (0.21 - 0.32) mSv and (0.22 - 0.33) mSv, respectively. The estimated annual effective dose received by beta radiation was in the interval of (0 - 0.04) mSv. Conclusion: For all investigated locations, excess lifetime cancer risk (ELCR) was below the recommended risk value.
