Per- and polyfluoroalkyl substances and nanoplastics frequently co-occur in environmental matrices, yet the effects of co-exposure on cellular responses upon ingestion are poorly understood. Here, we exposed human intestinal Caco-2 cells to perfluorooctanesulfonic acid, nanoplastics, and their combination. Cell painting-based phenomics was used to map phenotypic alterations across subcellular structures, and untargeted metabolomics using ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was employed to assess metabolic changes. Results show that perfluorooctanesulfonic acid predominantly affected the actin cytoskeleton, Golgi apparatus, and plasma membrane, while nanoplastics primarily targeted mitochondria. Combined exposure disrupted the endoplasmic reticulum, RNA, and mitochondria. Perfluorooctanesulfonic acid reduced levels of carnitines, free fatty acids, nucleotides, and sugars, whereas nanoplastics inhibited ceramides, triglycerides, sphingomyelins, and additional free fatty acids. Combined exposure produced a metabolic profile resembling that of nanoplastics, with specific differences attributed to perfluorooctanesulfonic acid. Overall, nanoplastics appear as the main drivers of the co-exposure effects.
Introduction: Carcinomas of the right and left sides of the colon are considered different types of cancer due to their different carcinogenesis, epidemiology, pathology and prognosis. Although several studies have described the prevalence and incidence of colorectal carcinoma (CRC) in the different colonic segments, more epidemiologic data are still needed to better understand the implications and relationship to sociodemographic and clinical variables. The aim of this study is to determine the anatomic location and histologic grade of CRC, to investigate the differences in patient gender and age, and to determine the correlation of gender and age with the anatomic location and histologic grading of CRC. Methods: A retrospective study was conducted covering the period from January 2013 to December 2022. Demographic data (gender and age), histological type and anatomical location of the tumor were observed. The study included all patients in the observed period with a diagnosis of colorectal cancer (CRC) at different anatomical locations and with different grades of histological staging. All patients had adenocarcinoma. Patients were divided into four age groups based on their gender (20-40 years, 41-55 years, 56-65 years and over 65 years old). Tumors of the colon ascending to the splenic flexure are defined as tumors of the right side, and distal to the splenic flexure as tumors of the left side of the colon. Results: A total of 183 patients were included in the study. Patients were between 38 and 82 years old, with a mean age of 64.3 ± 8.9 years. No statistically significant difference was found in the proportion of anatomical localization of CRC (p > 0.05). The most common anatomical location of CRC over the 10-year period was found to be the rectum 42.1% and the ascending colon 14.2% and transverse colon 13.1%, with no statistically significant difference in cancer incidence between the right and left sides of the colon. Histologic grade II was predominant in 57.4% of patients. A moderate negative correlation was found between age and histologic grade of CRC (r = −0.067), with no statistically significant difference (p > 0.05). Conclusion: No statistically significant difference was found in the anatomical localization of CRC between the right and left side of the colon. Histologic grade II CRC was the most prevalent. A moderate negative correlation was found between age and histologic grade of CRC.
The object of the study is the process of compressing noisy images in a lossy manner by better portable graphics (BPG) encoder. The subject of the study is the method for adaptive selection of the coder parameter Q depending on noise intensity and image complexity. The goal of the study is to consider the basic characteristics of lossy compression of remote sensing images contaminated by additive white Gaussian noise with giving recommendations of preferable Q setting. Methods used: numerical simulation, verification for test images. Results obtained: 1) the dependencies of compression ratio on Q are monotonically increasing functions; 2) their characteristics are strongly dependent on noise intensity and image complexity; 3) dependencies of logarithm of CR on Q contain information on possible existence and position of optimal operation point for compressed noisy images; 4) compression ratios for large Q contain information on image complexity with low sensitivity to noise presence and intensity; 5) it is possible to get useful information from dependences of compression ratio on Q. Conclusions: the results of this research allow: 1) estimating image complexity; 2) adapting Q to noise intensity and image complexity.
The historical industrial waste deposit Gater was used to dispose of different metallurgy wastes from lead and zinc production. The metallurgical waste deposit was situated in the open space, between the tailing waste deposit Žitkovac and river Ibar flow. Large amounts of lead-containing wastes are produced in the non-ferrous metallurgical industry, such as lead ash and lead slag generated in Pb smelting, lead anode slime, and lead sludge produced in the raw lead refining process. In addition to the lead concentration, numerous valuable components are found in the lead refinery waste from the group of Critical Raw Materials, such as antimony, arsenic, bismuth, copper, nickel, magnesium, scandium, as well as Rare-Earth Elements. Samples with eight characteristic points were taken to obtain relevant data indicating a possible recycling method. The chemical composition analysis was conducted using ICP; the scanning was completed using SEM-EDS. The mineralogical composition was determined by using XRD. The chemical analysis showed a wide range of valuable metal concentrations, from Ag (in the range from 14.2 to 214.6, with an average 86.25 mg/kg) to heavy metals such as Cu (in the range from 282.7 to 28,298, with an average 10,683.7 mg/kg or 1.0683% that corresponds to some active mines), Ni and Zn (in the range from 1.259 to 69,853.4, with an average 14,304.81 mg/kg), Sc (in the range from 2.4 to 75.3, with an average 33.61 mg/kg), Pb (in the range from 862.6 to 154,027.5, with an average 45,046 mg/kg), Sb (in the range from 51.7 to 18,514.7, with an average 2267.8 mg/kg), Ca (in the range from 167.5 to 63,963, with an average 19,880 mg/kg), Mg (in the range from 668.3 to 76,824.5, with an average 31,670 mg/kg), and As (in the range from 62.9 to 24,328.1, with an average 5829.53 mg/kg). The mineralogy analysis shows that all metals are in the form of oxides, but in the case of As and Fe, SEM-EDS shows some portion of elemental lead, pyrite, and silica-magnesium-calcium oxides as slag and tailing waste residues. The proposed recovery process should start with leaching, and further investigation should decide on the type of leaching procedure and agents, considering the waste’s heterogeneous nature and acidity and toxicity.
Background and Study Aim. Although physical activity (PA) is an important determinant of physical fitness (PF) in children, studies have rarely examined the associations between PA and PF in early school-age children within narrow age spans. The aim of this study was to evaluate the associations between different intensities of PA and various indices of PF in children aged 9 -11 years. Material and Methods. The participants were 121 children aged 9 - 11 years (49 girls) who were tested for PF (anthropometrics, aerobic endurance, upper body and abdominal strength, jumping power, mobility and flexibility), and the PA was directly measured via GeneActiv triaxial accelerometers. A t test was used to define differences between sexes, while Pearson’s correlations between PA variables and PF indices and multiple regressions for PF criteria were used to calculate sex stratification. Results. Compared with girls, boys achieved better results in terms of jumping power capacity, upper body strength, and aerobic endurance, and they had a higher number of steps taken per day, and a higher amount of vigorous PA per day (all p < 0.05). The girls achieved better results in terms of flexibility and mobility. Correlations between PA-intensities and PF were weak to moderate. Multiple regression calculations revealed that vigorous PA was a significant predictor of jumping power, upper body strength, and aerobic endurance in boys (16%, 20%, and 13% of the explained variance, respectively) and jumping power in girls (18% of the explained variance). Moderate PA was a significant partial regressor of aerobic endurance in girls (13% of the explained variance). Conclusions. Tailoring physical-education curricula to gender-specific PA responses and expanding PF assessments can enhance student engagement, optimize fitness outcomes, and improve the overall effectiveness of physical education programs.
IntroductionCOVID-19, caused by the SARS-CoV-2 virus, has resulted in a global public health crisis with a wide spectrum of clinical manifestations, ranging from asymptomatic infections to severe pneumonia. This study explores the association between various biomarkers and COVID-19 progression, aiming to identify early indicators of disease severity and enhance patient management.Materials and MethodsThe study included 750 confirmed COVID-19 patients categorized into four groups based on disease severity. Patients were recruited at the General Hospital in Tešanj, Bosnia and Herzegovina. All biochemical, hematological and coagulation parameters were analyzed using standard IFCC protocols.ResultsThe study identified significant differences in biochemical, hematological, and coagulation biomarkers across varying COVID-19 severities. Key markers such as C-reactive protein (CRP), D-dimer, lymphocyte count, erythrocyte sedimentation rate (ESR), and platelet count were analyzed. Elevated CRP and D-dimer were strongly linked to severe cases, while decreased lymphocyte count, elevated ESR, and platelet abnormalities were also associated with increased disease severity.ConclusionsOur study highlights the vital role of specific biochemical, hematological and coagulation parameters in predicting COVID-19 severity. Integrating these findings into clinical practice could enhance timely risk stratification, early intervention, and improved outcomes for affected individuals.
Ticks are key vectors of zoonotic pathogens, and their expanding distribution in Europe heightens public health concerns. In Bosnia and Herzegovina, while tick distribution is well documented, molecular data on tick-borne pathogens remain limited. This study aimed to illustrate the presence and diversity of these pathogens, focusing on areas with high human activity. Ticks (n = 556) were collected in April 2022 from eight diverse locations, including urban parks, private properties, and rural sites. PCR-based screening was employed to detect Anaplasmataceae, Borrelia, Francisella, Piroplasmida, Rickettsia, and tick-borne encephalitis virus (TBEV), with subsequent sequencing to confirm results. Further characterization of Borrelia burgdorferi sensu lato was achieved via reverse line blotting (RLB) hybridization and sequencing. Ixodes ricinus was the most prevalent species, followed by Dermacentor marginatus and D. reticulatus. Our analysis revealed an overall infection rate of 22.1% in questing ticks, with Rickettsia spp. and Borrelia spp. predominating. Notably, seven Borrelia species were identified in I. ricinus, alongside Anaplasma phagocytophilum, Rickettsia helvetica, and R. monacensis, with co-infections mainly observed in peri-urban areas. This study provides the first molecular evidence of multiple tick-borne pathogens in the region, underscoring the need for further surveillance and risk assessment of tick-borne diseases in the region.
Introduction: Various studies conducted in the past few years have shown a causal relationship between human papillomavirus(HPV) and benign and malignant lesions on the laryngeal mucosa. There are no other studies on the association between HPV and laryngeal lesions in Bosnia and Herzegovina. The aim of the study was to investigate the influence of HPV infection on the development of benign and malignant lesions in the larynx. Methods: Samples for the recommended HPV analysis were taken using cotton swabs from Digene’s Specimen Collection Kit (Sample Collection Kit) from the surface of the affected area of the laryngeal mucosa with a gentle rotational movement through the directoscope. Detection of the presence of HPV in the endolaryngeal swab was performed using Digene’s HPV test-Hybrid Capture II, and results were obtained on a DML 2000 luminometer.Results: In this study, a total of 40 patients were enrolled. Among them, 17 cases (42.5%) presented with benign lesions of the larynx, whereas 23 cases (57.5%) had malignant lesions. Within the group of 17 cases with benign lesions, 5 tested positive for HPV: 2 for high-risk HPV (HR HPV), 2 for low-risk HPV (LR HPV), and 1 for both high-risk and LR HPV. Among the 23 cases with malignant lesions, 11 (47.83%) were HPV positive: 5 for HR HPV, 4 for LR HPV, and 2 for both high-risk and LR HPV. Conclusion: Our findings underscore the noteworthy influence of HPV infection on both benign and malignant changes in the laryngeal mucosa. However, future studies necessitate larger sample sizes and the identification of specific virus types.
Introduction: The impact of nutrition on human health has become a central topic in modern research. The Mediterranean diet, rich in fruits, vegetables, fish, whole grains, and olive oil, has been associated with a lower risk of cardiovascular diseases. However, the effects of non-Mediterranean diets, particularly among students, remain insufficiently explored. This study aimed to examine differences in the dietary habits of health sciences students in two cities in Bosnia and Herzegovina (Mostar and Sarajevo) and Split, Croatia. Methods: A cross-sectional descriptive study was conducted between February and November 2024, including 473 students (Mostar: 125, Sarajevo: 230, Split: 118). Dietary habits were assessed using a validated food frequency questionnaire and the Mediterranean Diet Adherence Screener. Statistical analysis included Pearson’s chi-square test, with significance set at p < 0.05. Results: Students from Split showed significantly higher adherence to Mediterranean dietary habits, including greater consumption of vegetables (p = 0.009), fish (p = 0.035), legumes (p = 0.036), and tomato sauce (p = 0.022). Students in Sarajevo reported the highest intake of sugary drinks (p < 0.01), while those in Split consumed the least margarine and cream-based fats (p = 0.003). No significant differences were found in fruit consumption. Conclusion: Given the importance of diet in preventing chronic diseases, targeted nutrition education programs are needed to promote healthier eating habits among students. Future research should explore the underlying causes of these dietary differences and their long-term health implications.
BackgroundPostoperative atrial fibrillation (POAF) is the most common complication associated with higher mortality rates, prolonged hospitalization, and increased treatment costs.The aimof this cross-sectional longitudinal study is to compare the incidence of POAF after coronary artery bypass grafting (CABG) performed with different surgical techniques. The primary outcome is defined as a heart rhythm disorder with atrial fibrillation characteristics that lasts longer than 5 min or requires treatment due to clinical instability.MethodsThe study included 229 hemodynamically stable patients with isolated coronary artery disease who underwent elective CABG. 153 patients underwent CABG with use of cardiopulmonary bypass (ONCAB) and 76 patients without it (OPCAB). In the preoperative risk assessment with modified score, the risk of POAF was higher in the ONCAB group.ResultsPOAF occurred in 86 (37.55%) of a total 229 patients. The number of new cases of POAF is lower in the OPCAB 36 (15.72%) compared to 50 (21.83%) in the ONCAB group (p = 0.031). In the postoperative period there was a significant difference in the time of onset of the primary outcome, the time spent in the IUC and the length of hospitalization.ConclusionPOAFs are more common in ONCAB operating technique. The OPCAB technique reduces postoperative complications, shortens the stay in the IUC and the length of hospitalization, and reduces treatment costs.
Comparative analysis of red mud reduction techniques was performed using both carbothermal and hydrogen-based reduction methods, combining thermochemical modeling and experimental validation. The reduction process is mostly important because of the high contamination risk assessment of soil with disposed red mud. Therefore, the minimization of red mud during the reduction process can be a novel strategy for the production of metallic iron and solid residue for hydrometallurgical treatment. Different strategies of hydrogen and carbon reduction in static and dynamic conditions were studied between 700 °C and 1700 °C. The separation of solid residue and formed iron was analyzed using magnetic separation. The main aim was to study the advantages and disadvantages of using decarbonizing technologies for the treatment of red mud, aiming to develop an environmentally friendly process. Thermochemical analysis of the reduction offered new data about mass losses during our process through the evaporation, thermal decomposition, and formation of metallic carbide.
During the lifespan, graphic products are exposed to various external factors. During their use, their properties(physical, mechanical, visual, etc.) change to a greater or lesser extent. It is necessary to observe/monitor changesand influence of external factors on their properties as soon as the product is created. The aim of this research is toexamine the impact of the aging process on the quality of inkjet printing. A different number of layers of black ink (in10 % tonal value (TV) and 100 % TV) and a different number of varnish layers were printed on PVC foil material. The samples were exposed to xenon light (λ > 300 nm) to accelerate the ageing process over a period of 72 and 216 h. They were measured by Datacolor spectrophotometer. As expected, with longer exposure time, greater changes occurred. According to the CIE ΔE*00 formula, the differences ranged from an imperceptible to a large colour change. After 72 h, the biggest changes in colour occurred in the K10 % with one ink layer and three layers of varnish. The smallest changes were in K100 % with one ink layer and no varnish. After 216 h, the greatest changes were observed in the K10 % sample with three layers of ink and two layers of varnish. The smallest differences were K10 % sample with one ink layer and without varnish.
The etiology of transmissible viral proventriculitis (TVP) of broiler chickens has been discussed since its initial recognition 40 years ago. Regardless of its low direct impact on mortality rate, it leads to high economic losses in the broiler industry through reduction of food conversion, weakening of birds, and their increased susceptibility to pathogens. The aim of the present study was to examine the potential presence of TVP on the broiler chicken farms in Bosnia and Herzegovina, to characterize microscopic lesions, and to investigate the viruses implicated in etiology of TVP by PCR-based methods. In total, 143 diseased broiler chickens from 16 farms in Bosnia and Herzegovina were euthanized and subjected to necropsy and subsequent histopathology of proventriculi. A representative number of proventriculi samples (n = 50) that exhibited histopathologic changes were processed for molecular detection of chicken proventricular necrosis virus (CPNV), girovirus (GyV3), chicken anemia virus (CAV), and infectious bursal disease virus (IBDV) by PCR-based methods. In addition, samples of bursa of Fabricius (n = 39) and spleen (n = 50) were tested for IBDV. Histopathology revealed changes consistent with TVP in 39.8% (57/143) and LP (lymphocytic proventriculitis) in 2.1% (3/143) of samples. All 50 proventricular samples showed positivity to CPNV with Ct values ranging between 18 and 26. GyV3 was detected in eight samples (16%), with Ct values ranging from 11.1 to 27.5. The presence of CAV was more prominent (38%), with 19 positive broiler chickens (Ct ranging from 9.6 to 35.6). Pooled samples of spleen, bursa, and proventriculi from three farms were positive for IBDV. The obtained results represent the first documented data on TVP and the first record of CPNV and GyV3 presence in broiler farms from Bosnia and Herzegovina.
INTRODUCTION Acute bacterial meningitis (ABM) is a serious infectious disease and medical emergency. Given the fact of its high mortality and morbidity, detecting prognostic factors is potentially useful in improving treatment strategies. This paper aims to determine prognostic factors of short-term outcomes of patients with ABM in a developing country - Bosnia and Herzegovina, measured by the Modified Rankin Scale (MRS) at discharge. METHODOLOGY In this retrospective cohort study, 56 patients treated at the Clinic of Infectious Diseases, Clinical Center University of Sarajevo, for 11 years (2012-2022) were included. Statistical analysis was performed using IBM SPSS Statistics version 29.0.1.0. RESULTS The subjects' average age was 31.6 ± 27.7 years, with the youngest patient being 4 months and the oldest 75 years old. Among those, 31 were male and 25 were female. Unfavorable outcomes had 16 (28.6%) patients, including fatal outcomes in four patients and severe disabilities in 12 patients (MRS: 2-6), while 40 (71.4%) patients had favorable outcomes (MRS: 0-1). In the multivariate analysis, predictors of unfavorable outcomes included age older than 60 years, duration of symptoms longer than 24 hours, presence of neurological defects at admission, impaired consciousness, respiratory distress, and no corticosteroid use during treatment. CONCLUSIONS There is certainly a window of opportunity for patients with ABM: The shorter the time between disease onset and treatment initiation, the better the disease outcome.
Biodentine, a tricalcium silicate cement, has emerged as a retrograde root-end filling material to promote periapical lesion (PL) healing after apicoectomy. However, its underlying mechanisms remain unclear. This study tested the hypothesis that Biodentine stimulates the osteogenic differentiation of mesenchymal stromal cells (MSCs) derived from PLs. The Biodentine extract (B-Ex) was prepared by incubating polymerized Biodentine in RPMI medium (0.2 g/mL) for three days at 37 °C. B-Ex, containing both released microparticles and soluble components, was incubated with PL-MSCs cultured in either a basal MSC medium or suboptimal osteogenic medium. Osteogenic differentiation was assessed by Alizarin Red staining and the expression of 20 osteoblastogenesis-related genes. Non-cytotoxic concentrations of B-Ex stimulated the proliferation of PL-MSCs and induced their osteogenic differentiation in a dose-dependent manner, with a significantly enhanced effect in suboptimal osteogenic medium. B-Ex upregulated most early and late osteoblastic genes. However, the differentiation process was prolonged, as indicated by the delayed expression of wingless-type MMTV integration site family member 2 (WNT2), bone gamma-carboxyglutamate protein (BGLAP), bone morphogenic protein-2 (BMP-2), growth hormone receptor (GHR), and FOS-like 2, AP-1 transcription factor subunit (FOSL2), compared with their expression under optimal osteogenic conditions. The stimulatory effect of B-Ex was primarily calcium dependent, as it was reduced by 85% when B-Ex was treated with the calcium-chelating agent EGTA. In conclusion, Biodentine promotes the osteogenic differentiation of PL-MSCs in a calcium-dependent manner, supporting its stimulatory role in periapical healing.
