Published: July 2024

Abstract
In high-frequency electronics, optimizing RF oscillators performance is essential, especially as applications reach into wide frequency bands. This article describes proposed clock generators for UWB sensor systems based on oscillators with dielectric resonator (DRO). Evaluation boards with different sizes of microstrip conductors were developed and tested, based on which new versions of boards were created. Improvements were made to integrate the DRO into a shielded box to ensure minimal external interference. The final designs demonstrated stable operation with low phase noise λ (1 MHz) = -108.805 dBc at fc = 21.732 GHz, sufficient power (3.65 dBm) and low power consumption(56 mW).
Code Clones: A Novel Approach to Detecting Plagiarism in Binary Decomposition of C Programs
Authors: Horváth Marek , Gurbál’ Filip 
Published: July 2024

Abstract
The escalation of code plagiarism in computer science education has necessitated the development of more sophisticated detection methods, particularly for binary files which pose a unique challenge. This study introduces a novel approach to plagiarism detection through binary decomposition, which decompiles binary files back into high-level code to reveal similarities that may be hidden at the binary level. The methodology is crucial for scenarios where students submit compiled programs, enabling the application of traditional code similarity analysis methods to detect instances of plagiarism. Statistical data on code similarity among student submissions in a C programming course are presented, highlighting the urgent need for robust detection strategies. This paper explores the ethical implications of plagiarism, the technical challenges of binary file analysis, and the potential for applying this technique across various programming languages and educational contexts.

Investor Agreement and the Volume Response to Information
Authors: Rauterkus Andreas 
Published: July 2024

Abstract
In this research, an empirical model, which proposes that informational events affect trading volume due to heterogeneous reactions and heterogeneous prior expectations, is tested. Belief dispersion both across and within two sub-groups that proxy for those who own and do not own a given security are measured. The impact of this dispersion on trading volume is also tested. The results suggest that both heterogeneous priors and heterogeneous reactions affect trading volume. However, it is found that any change (positive or negative) in dispersion across groups with heterogeneous prior expectations will result in an increase in trading volume.
The Issue of Inclusion in Secondary Schools from the Czech School Principals’ Point of View
Authors: Skutil Martin , Strouhal Martin 
Published: July 2024

Abstract
Since the introduction of new legislation in 2016, questions of inclusive policy have been constantly discussed not only in schools, but also among professionals, parents, and politicians. This article is part of a larger research survey mapping the state of inclusive education at all Czech Republic secondary schools. It presents the results for two regions in order to show what attitudes and views are held by principals on the implementation of inclusion in the education system. The research was carried out as a qualitative study and semi-structured interview were employed as the research method. The obtained data were analysed using the grounded theory method. The results show that inclusion is not generally accepted by school principals. There are schools that are very pro-inclusive, but there are also schools that fundamentally reject inclusion. Initial assumptions that inclusion has been best received by general secondary schools were not confirmed. On the contrary, it turns out that the type of school does not matter as much as the attitudes of the seniors’ pedagogical staff towards inclusion. Their behaviour and attitudes significantly influence the whole school climate, which is passed on to all actors as well as how the school functions overall in working with pupils with special needs.
Education Experts : Agents of Contemporary Educational Discourse?
Authors: Šimáková Monika 
Published: July 2024

Abstract
More and more experts from the social sciences are appearing in the media to provide expert opinions on media coverage of events and social issues. However, with regard to the conditions under which media content is produced, a growing number of voices have been pointing to the fact that quasi-experts with a media interest tend to speak more in the media than scientifically trained scholars. This article conducts an analysis of media outputs to examine whether this criticism is relevant to the field of education in the Czech media landscape, and the analysis shows that in almost half of cases the so-called “education experts” commenting on education in the media were quasi-experts – people to whom the authority and status to speak on education is attributed by the media – rather than scholarly experts. The analysis results in a classification of experts on education speaking in the Czech media – they usually choose similar rhetoric and accentuate only selected educational topics.
Pathohistomorphometric and Immuno-Histologic Changes in Early Arteriovenous Fistula Failure in Patients with Chronic Kidney Disease
Authors: Pushevski Vladimir , Dejanov Petar , Rambabova-Bushljetikj Irena , Petrusevska Gordana , Popov Zivko , Ivanovski Ninoslav 
Published: July 2024

Abstract

Background
Hemodialysis is a prevalent treatment for the end-stage chronic kidney disease (CKD) worldwide. The primary arteriovenous fistula (AVF), widely considered the optimal hemodialysis access method, fails to mature in up to two-thirds of the cases. The etiology of the early AVF failure, defined as thrombosis or inability to use within three months post-creation remains less understood, and is influenced by various factors including patient demographics, surgical techniques, and genetic predispositions. Neointimal hyperplasia is a primary histological finding in stenotic lesions leading to the AVF failure. However, there are insufficient data on the cellular phenotypes and the impact of the preexisting CKD-related factors. This study aims to investigate the histological, morphometric, and immunohistochemical alterations in the fistula vein, pre-, peri-, and post-early failure.

Materials and Methods
Eighty-nine stage 4-5 CKD patients underwent standard preoperative assessment, including the Doppler ultrasound, before a typical radio-cephalic AVF creation. Post-failure, a new AVF was created proximally. The vein specimens were collected during the surgery, processed, and analyzed for morphometric analyses and various cellular markers, including Vimentin, TGF, and Ki 67.

Results
The study enrolled 89 CKD patients, analyzing various aspects of their condition and AVF failures. The histomorphometric analysis revealed substantial venous luminal stenosis and varied endothelial changes. The immunohistologic analysis showed differential marker expressions pre- and post-AVF creation.

Conclusion
This study highlights the complexity of the early AVF failures in CKD patients. The medial hypertrophy emerged as a significant preexisting lesion, while the postoperative analyses indicated a shift towards neointimal hyperplasia. The research underscores the nuanced interplay of vascular remodeling, endothelial damage, and cellular proliferation in the AVF outcomes.

Abstract
The authors describe a kidney transplant procedure using a living donor with a large cyst and double arteries. Due to the lack of regular transplant activity from a deceased donors, we decided to use the, so called, expanded criteria living donors, which means older age (more than 65 years), hypertension, some structural anomalies of the kidneys (cysts, multiple renal arteries), ABO incompatible kidney transplant, etc. The surgical procedure was the unroofing of a large cyst and wadding with perirenal fat. The 10 years survival rate is quite successful and we can recommend it.

Published: July 2024

Abstract
Thromboembolic events are a common cause of morbidity and mortality with significant socioeconomic impact especially when young patients are affected. They are a rare medical event in young people and their clinical presentation can be mild or asymptomatic. The manifestation of symptoms and thrombotic events depends on both: the genetic mutations and the external risk factors that will induce the process. We present a case of a 34-year old young female, with three consecutive cerebrovascular insults in a period of ten years, and an acute myocardial infarction. There is a combination of gene mutations and polymorphism, with a predisposition to thromboembolic events. We emphasized the role of e-NOS (Endothelial nitric oxide synthase 786 T>C mutation) and the connection with smoking. The dual effect of the prolonged smoking and dysfunctional nitric oxide synthase in our young patient led to several thrombotic events. We discussed the various diagnostic tests and possible therapeutic and prophylactic strategies.

Abstract
Membranoproliferative glomerulonephritis (MPGN) is a rare glomerular disease characterized by mesangial hypercellularity and thickening of the glomerular basement membrane (GBM). MPGN can be idiopathic or associated with malignancy, systemic immune complex disorders and chronic infections. It has rarely been associated with solid organ tumors, such as lung, gastric, breast or prostate cancer. We report a patient with MPGN and coexisting colorectal carcinoma.
A 48-year-old man presented with anemia, loss of weight, hypertension, and nephrotic syndrome. The renal biopsy findings were compatible with type 1 MPGN. The antineutrophilic cytoplasmic antibodies, antinuclear antibodies, anti-GBM, serologic markers of hepatitis B and hepatitis C and tumor markers were negative. After ruling out the secondary causes of MPGN, the patient was treated with pulse doses of methylprednisolone and a single dose of cyclophosphamide. However, due to the worsening anemia and rectal bleeding, a colonoscopy was performed, which established a diagnosis of adenocarcinoma of the descending colon. The patient was treated with left hemicolectomy and oral corticosteroids. Within a year after the cancer treatment, the patient experienced a complete resolution of the proteinuria and improvement of the kidney function.
Although rare, MPGN can be associated with hematologic malignancies and solid organ tumors. The most common causes of secondary MPGN should be ruled out before starting specific treatment. In our patient, cancer treatment has led to a subsequent remission of the nephrotic syndrome, which indicated that this association was not coincidental but rather causal. In patients with a tumor and concomitant glomerulopathy which is suspected to be paraneoplastic in etiology, the treatment of the underlying malignancy should be prioritized.

Published: July 2024

Abstract

Objective: Acetylsalicylic acid (ASA) is the most widely used antiplatelet agent in treating ischemic strokes. ASA resistance varies between the populations, from 5% to 60%. We aimed to determine the prevalence of ASA resistance in our population, its association with demographic characteristics, risk factors, and the occurrence of recurrent ischemic stroke (IS). (IST).

Methods: One hundred consecutive patients with primary or recurrent IS were prospectively included. Strokes were diagnosed with computed tomography (CT) or magnetic resonance imaging (MRI). In all patients a detailed history of cardiovascular risk factors and fasting blood analyzes (blood count, glycemia, HbA1c, degradation products, lipid profile) were taken, and the ASA resistance was examined with the Innovance PFA 200 system. The ASA resistance was examined after a minimum of 1 month of regular use of ASA 100 mg per day.

Results: The prevalence of ASA resistance was 32%. ASA-resistant patients were statistically significantly older (69.9±7.5 vs, 61±1 y., p<0.05), and of male gender (75 vs, 45.6%, p<0.05). Previous cardiovascular diseases were statistically significantly more common in the ASA-resistant patients compared to the ASA-sensitive patients (46.8 vs 26.5%, p<0.05). The presence of recurrent stroke in the ASA-resistant versus ASA-sensitive patients was statistically significant (75% vs. 22.05%, p<0.0001). There was no statistically significant difference in the investigated laboratory parameters and the risk factors between the ASA-resistant and the ASA-sensitive patients.
Conclusion. The prevalence of ASA resistance in our population is high. According to our results, ASA resistance testing should be done in the older male individuals with a previous burden of cardiovascular diseases.

Abstract

Introduction: Tumor budding (TB) is considered to be a morphological and prognostic factor relevant to colon cancer (CC). The aim of our study is to assess the TB and to evaluate its relationship to clinicopathological findings within stage II and III CC patients as a single center experience.

Materials and methods: A total of 120 CC patients operated between 2018 and 2021 at the University Clinic of Digestive Surgery in Skopje, the Republic of North Macedonia were included in this retrospective, single center study. TB was evaluated by the magnification of 200x along the invasive front of the primary tumor on H&E and CKAE1/AE3 immunohistochemically stained sections. Two grades were used: low grade (TB1, 0-4 TBs) and high-grade, which includes intermediate (TB2, 5-9 TBs) and high grade (TB3 ≥10TBs) of TBs.

Results: A statistically significant correlation has been identified between high-grade TB and age (p=0.05) of the patients. There was also a significantly higher occurrence of high-grade TB in patients within stage III CC. Statistically significant correlations were also found in lymph node status (p<0.01), vascular invasion (p<0.05), lymphatic invasion (p<0.01), postoperative relapse (p<0.01), and death (p<0.01). Tumor relapse and death were significantly more frequent in patients with high-grade TB than those with low-grade TB. Patients with registered high-grade TB demonstrated significantly lower relapse-free survival (RFS) and overall survival (OS) rates than patients with low-grade TB over the observation period (RFS: 53.8% vs. 98.5%, p<0.001; OS: 65.4% vs. 97.1%, p<0.001, respectively). Patients with lung and liver postoperative relapses had higher percentage of cases with high-grade TB (94.1%).

Conclusion: Our results are highly suggestive that TB should be included as a histological biomarker in the pathology report of patients with stage II and stage III CC, because of its prognostic value.
