Nanotechnology has shown its great potential in different fields of science such as medicine and pharmacy. This paper presents a review on artificial neural networks used in nanotechnology based on information gathered from different research. It is important to understand applications of artificial neural networks so that they can be used even more efficiently in future applications. Research papers summarized and compared here show different results in two fields of science. Artificial neural networks were made and proven to be useful in diagnostics and tracing diseases. The pharmaceutical industry has also shown to be a good candidate for the development of ANNs on the nanotechnology level. Regression analysis was used as a statistical method for presenting the best results from both fields observed. Root mean square error and mean error were calculated to measure the differences between values predicted by a model and the values actually observed from the environment that was being modelled. Based on individual results, each of the ANNs made were accurate enough to be considered as a diagnostic tool in fields of medicine and pharmacy. Performance is greater than 90% 10 out of 12 times, which is viewed in this paper. The multilayer perceptron ANN is mostly used. Based on the latest results, in upcoming years, one can expect better understanding and more research in the field of ANN applications in nanotechnology.

Today's systems are being built to connect to public or semi-public networks, are able to communicate with other systems, e.g., in the context of Internet-of-Things (IoT), involve multiple stakeholders, have dynamic system reconfigurations, and operate in increasingly unpredictable environments. In such complex systems, assuring safety and security in a continuous and joint effort is a major challenge, not the least due to the increasing number of attack surfaces arising from the increased connectivity. In this paper we present an approach that aims to bridge the gap between safety and security engineering. The potential of the approach is illustrated on the example of E-gas system, discussing the cases when unintentional faults as well as malicious attacks are taken into consideration when assuring safety of the described system.

In context of safety-critical Systems of Systems (SoS) that are built as a collection of several systems capable of fulfilling their own function as well as the overall SoS function, increase production efficiency and decrease human effort in such systems, one has to be able to guarantee critical properties such as safety and security. It is not sufficient to analyze and guarantee these critical properties isolated one from another, but one has to be able to provide joint analysis and guarantees on safety and security. This paper is our initial effort towards building a common safety and security assurance approach for complex SoS, where we start from identification and analysis of attack models and connecting them to the already identified functional safety requirements. In this way we will be able to assess system assets and vulnerabilities, and identify ways how an attacker could exploit them. We aim to connect attack modeling process to safety process by aligning mitigation strategies with safety requirements.

Background: Nephrotic syndrome (NS) is one of the most frequent glomerular diseases among children. While most of the children with primary NS respond to steroid treatment, 10 to 20% of the patients are steroid-resistant, and the best therapy for such cases has never been defined. Objective: The present study aimed to evaluate steroid-resistant nephrotic syndrome (SRNS) patients. Materials and methods: Our research included 50 children (56% female and 44% male) with NS. NS was defined as the presence of edema, massive proteinuria, hypoalbuminemia and hyperlipidemia. Patients with NS were treated according to international protocol. SRNS was diagnosed in patients with idiopathic NS based on lack of complete remission despite treatment with steroids. Renal biopsy was performed in 22 patients with SRNS at the Pediatric Clinic II of the University Clinical Center in Sarajevo (UCCS). Histopathologic analyzes of renal biopsy were performed at the Department of Pathology, University Clinical Center in Tuzla (UCCT). Patients with SRNS, after kidney biopsy were treated with nonsteroidal immunosuppressant’s. Results: Eight (36.4%) of the 22 patients who had undergone renal biopsies had minimal change disease (MCNS) and seven (31.8%) had focal segmental glomerulosclerosis (FSGS). The immunosuppressive drugs used in SRNS were Cyclosporine (CsA), Cyclophosphamide (CYC), Mycophenolat mofetil (MMF) and Rituximab (RTX). Three patients (13.6%) did not respond to any treatment and had developed end - stage renal disease (ESRD). Conclusion: With current treatments, some children will ultimately achieve a sustained remission with one of the second line or third line of the proposed drugs. Patients with refractory NS will go to progression towards ESRD. The rapid development of molecular genetics will give a new contribution to the pathogenesis and treatment of this disease.

Objective: To investigate the efficiency and safety of the fixed combination of perindopril/amlodipin in a treatment if grade I and grade II arterial hypertension and arterial stiffness values after only two weeks of treatment. Design and method: The open clinical prospective controlled study was designed. The study was designed for two weeks and two group were formed. The first group was comprised of arterial hypertension grade I patients and group 2 of arterial hypertension grade 2. The cardiovascular risk profile was notified for all patients. The peripheral and central blood pressure, pulse wave velocity, stroke volume, augmentation index, pulse pressure, heart rate, the reflection index were analyzed before and two weeks after treatment. For the grade I arterial hypertension the fixed combination of perindopril/amlodipin was used in a dose of 5 mg/5 mg, and for grade 2 arterial hypertension dosage was 10 mg/10 mg. Therapy was given as a single tablet advised to be taken in the evening. The average grade I hypertension values were 158/92mmHg, and for grade II the average value was 162/102mmHg. The average vascular age for grade I arterial hypertension was 4,5 years, and for grade II arterial hypertension the average vascular age was 8,5years. Results: Results obtained from this short study showed significant lowering of blood pressure and the improvement of arterial stiffness values and in the vascular age was detected as well in both group. The average values of arterial hypertension felt within normal range after treatment in a both groups after two weeks of therapy. Patient compliance and satisfaction was notified. There were no side effects. Conclusions: The fixed combination of perindopril/amlodipin in a dose of 5 mg/5 mg for grade I arterial hypertension and 10 mg/10 mg for grade II arterial hypertension was proven to be effective in all patients. No adverse events were observed. The compliance of patients was excellent and evening dose is more preferable than morning regime. The arterial stiffness values are not constant and permanent. They are rather flexible and arterial hypertension values major dependent. The lower arterial hypertension, the lower arterial stiffness and vasc ular age.

Objective: The aim of this study was to evaluate corelation of serum level of NGAL to severity of hypertension and diastolic disfunction in patients with ST- segment elevation myocardial infarction treated with fibrinolytic therapy. Design and method: We included 54 consecutive ST-segment elevation myocardial infarction patients treated with fibrinolytic therapy (alteplase). The median follow-up time was 6 days (interquartile range, 5 to 7 days). Blood samples were drawn immediately after admission prior to fibrinolytic administration. The endpoints were mean systolic and diastolic pressure (continuously monitored) and mean E/A ratio as a measure of diastolic function. Results: Patients with high NGAL (above 134,05 &mgr;g/l; 75th percentile) had significantly higher mean systolic and mean diastolic blood pressure compared to patients with low NGAL (under 134,05 &mgr;g/l; 75th percentile), p = 0,001 and p = 0,003; respectively. Patients with high NGAL (above 134,05 &mgr;g/l; 75th percentile) had significantly lower E/A ratio compared to patients with low NGAL (under 134,05 &mgr;g/l; 75th percentile), p = 0,004. Conclusions: High NGAL significantly corelates with severity of hypertension and diastolic dysfunction in patients with acute STEMI.

In a traditional teaching models students are passive learners and usually share a common learning path that is in most cases predefined and fixed. In this paper we describe the case-based model for personalized learning path recommendation in example-based learning activities. According to the proposed model, the primary source of the knowledge for recommendation is represented in the form of cases that represent previously experienced learning paths. A recommended learning path comprises appropriate learning examples and learning resources for a student to go through in order to achieve desired learning outcomes. To validate the effectiveness of the proposed model, we conducted an experimentation to evaluate the impact of the model to student learning progress.

Satureja subspicata and S. horvatii are endemic species of the Balkan Peninsula and often used in traditional medicine in Bosnia and Herzegovina to treat different health conditions. We aimed to analyze the unevaluated apoptotic, genotoxic and cytotoxic effects of two Satureja species, as well as their content of phenolics that are mainly responsible for the plant's biological activity. Apoptotic and geno/cytotoxic activities of S. subspicata and S. horvatii were investigated in vitro in human lymphocyte culture and in vivo in mice. The content of the main phenolics in plant extracts was determined by ultra-high pressure liquid chromatography-MS-MS (UHPLC–MS/MS). Genotoxic and cytotoxic activities of Satureja extracts were evaluated in vitro by applying a cytokinesis-block micronucleus cytome assay in human lymphocyte culture and in vivo applying a mice reticulocytes micronucleus assay. SALSA RT-MLPA R011-C1 apoptosis assay was used for measuring the relative expression of 44 genes associated with the regulation of the apoptotic pathways in human lymphocyte cultures treated with different concentrations of two Satureja extracts. The first analysis of phenolic compounds in S. horvatii and S. subspicata determined by an UHPLC-MS/MS method revealed high levels of rosmarinic and caffeic acids. Minor genotoxic potential was determined in relation to the tested concentrations while no cytostatic and cytotoxic effects were revealed in vitro. However, when applied in concentrations of 200 mg/kg per os, aqueous extracts of two Satureja species significantly decreased frequency of reticulocytes micronuclei in treated mice against controls. Extracts of S. subspicata and S. horvatii in concentrations of 0.2 mg/mL, regardless of solvent used, downregulated pro-apoptotic and upregulated anti-apoptotic genes, showing anti-apoptotic activity. Our results indicate that the registered anti-genotoxic and anti-apoptotic activity is most likely related to the high level of phenolic acids (particularly rosmarinic and caffeic) in the tested extracts.
