Do stone size and impaction influence therapeutic approach to proximal ureteral stones?

Background/Aim. Primary therapeutic approach to lumbar ureteral stones is still contraversial. The aim of the study was to investigate the influence of stone impaction and size on the effectiveness of proximal ureteral stone lithotripsy. Methods. A total of 123 patients with proximal ureteral stones were investigated in this prospective study performed in a 10- month period. The patients were divided into the group I - 86 patients treated with extracorporeal shock wave lithotripsy (ESWL) and the group II - 37 patients treated with 'Swiss' Lithoclast. In the group I, 49 stones (57%) were classified as impacted, while 20 stones (23.3%) were larger than 100 mm2. In the group II, 26 stones (70.3%) were impacted, and 11 stones (29.7%) were larger than 100 mm2. Stones were defined as impacted by the radiographic, echosonographic as well as endoscopic findings in the group II of patients. Stone size was presented in mm2. Chemical composition of stones were almost the same in both groups of the patients. Results. Generally, there was no statistically significant difference in the treatment success between the groups. However, stones larger than 100 mm2 were statistically more successfully treated endoscopically, while there was no statistical difference in the treatment success of impacted stones between these two groups. Conclusion. ESWL can by considered as primary first therapeutic approach in treatment of all proximal ureteral stones except for stones larger than 100 mm2 that should primarily be treated endoscopically

RESEARCHING AND PLANNING THE RURAL SPACE: THE WORK OF BRANISLAV KOJIĆ

An architect and ruralist, professor and academician, Branislav Kojić made a remarkable contribution to the study of village architecture and villages, their design and planning. His approach was thorough, systematic, comprehensive and interdisciplinary, and resulted in the establishment of a special trend in the study of the village in these regions — “ruralism”. His research had interregional aspect, encompassing space of all the six former republics of the Socialist Republic of Yugoslavia, and with consideration of local and regional specificities. Creativity of Branislav Kojić united the elements of architecture, urbanism, ethnology, human geography, and allowed the filling of gaps in the former knowledge and approaches to rural issues. In order to present Branislav Kojić’s scientific opus and contribution, the paper presents the basic lines of his work, thinking and development of ideas, following the hierarchy of spatial units - from a rural house, a courtyard, through a village atar, a rural settlement, a system of settlements and a rural region, and finally to the villages in the regional spatial frames

Application of FeAl-LDH@SiO2 for Phosphate Removal from Water

In present study FEAL-LDH@SIO2 were Used for removing phosphate from aqueous solutions. FeAl-LDH with molar ratio Fe/Al = 3/1 was synthesized by co- precipitation from aqueous solutions in the present of SIO2 PARTICLES. Silica obtained from rice husks were used as a substrate for the deposition of LDH particles. The prepared material was characterized by scanning electron microscope (FE-SEM), X-ray diffraction (XRD), N2 adsorption/desorption isotherms (BET method) and Fourier transform infrared spectroscopy (FTIR). XRD analysis showed that Fe-Al had formed LDH structure. SEM analysis revealed deposition of LDH particles on SIO2 SUBSTRATE. The adsorption characteristics for phosphate uptake of the obtained material were performed. Adsorption experiments were carried out as a function of LDHs dosage with three different mass ratios of LDH/silica = 1/1, 2/1, and 3/1 and different phosphate concentration AT INITIAL PH 4. Phosphate concentrations were determined using spectrophotometer. The results showed that the maximum sorption capacities of phosphates calculated based on Langmuir equation was 52.68 mg g-1.The book of abstract available at: [http://conf.univerzitetpim.com/wp-content/uploads/2022/06/Book-of-Abstracts_2022-1.pdf

A gold nanoparticles and hydroxylated fullerene water complex as a new product for cosmetics

Three types of gold nanoparticles (AuNPs) were synthesised with a custom-made Ultrasonic Spray Pyrolysis (USP) device, from aqueous solutions of gold (III) chloride (AuCl3) and gold (III) acetate (AuC6H12O6), with an initial concentration of Au 0.5 g/L. AuNPs were collected in suspensions of deionised (D.I.) water with the stabilisers polyvinylpyrrolidone (PVP) or polyethylene glycol (PEG), followed by the process of freeze drying the AuNPs to be useful as a new additive for the cream. The standard cream base was used as a matrix for preparation of three types of cream with AuNPs in the same concentration ratios. The third AuNPs cream was prepared with a patented hydroxylated fullerene water complex (3HFWC-W) matrix. To examine the effect of AuNPs as additive in creams, a six-week study of test creams was conducted on 33 volunteers with no dermatological diseases. During the study three main parameters of the skin where measured: Collagen quality, skin moisturisation and the epidermis-dermis function. The results of the study found improvements of collagen quality between 18-24 %, achieved due to the use of AuNPs in standard creams, while the cream with the combination of 3HFWC-W and AuNPs gave significantly higher improvements with a value of 45.7 %. It was also discovered that hydration of the skin (stratum cornum) increased by 6.4-9.6 % in standard creams with AuNPs, and 73.7 % in the 3HFWC/AuNPs' cream. Similar results were measured by the epidermisdermis function, where 24-28 % improvement for standard creams with AuNPs was identified, and 38.4 % for the cream 3HFWC-W/AuNPs

SECULAR TRENDS OF CHILDREN AND ADOLESCENTS AS A BASIS FOR PLANNING AND PROGRAMMING OF PHYSICAL ACTIVITY

Naučni skup „Nauka i nastava u vaspitno-obrazovnom kontekstu”, održan 23. oktobra 2020. godine na Pedagoškom fakultetu u Užicu Univerziteta u Kragujevcu.A comprehensive understanding of the secular trends in physical activity of children and adolescents is necessary for public health, due to the significant impact of this factor on health. Regardless of body weight, cardiorespiratory endurance in children is associated with multiple metabolic risk factors, and adolescents with low values ​​of cardiorespiratory endurance are more likely to develop hypertension in adulthood, even with a normal body mass index. The level of motor abilities during childhood and adolescence has been identified as a significant factor influencing the overall daily level of physical activity and maintaining normal body weight values ​​in adulthood. Physical education classes should play a key role in improving the physical activity of children and adolescents because they represent a social impact that encompasses the widest part of the population of the appropriate chronological age. Promoting a healthy lifestyle through finding effective ways to maintain physical activity, within the recommended limits for children and adolescents, is essential for the future of the population and has a tremendous economic, social and demographic impact on the future of each country.Publishe

Timing Is Important—Management of Metabolic Syndrome According to the Circadian Rhythm

Physiological processes occur in accordance with a rhythm regulated by the endogenous biological clock. This clock is programmed at the molecular level and synchronized with the daily light–dark cycle, as well as activities such as feeding, exercise, and social interactions. It consists of the core clock genes, Circadian Locomotor Output Cycles Protein Kaput (CLOCK) and Brain and Muscle Arnt-Like protein 1 (BMAL1), and their products, the period (PER) and cryptochrome (CRY) proteins, as well as an interlocked feedback loop which includes reverse-strand avian erythroblastic leukemia (ERBA) oncogene receptors (REV-ERBs) and retinoic acid-related orphan receptors (RORs). These genes are involved in the regulation of metabolic pathways and hormone release. Therefore, circadian rhythm disruption leads to development of metabolic syndrome (MetS). MetS refers to a cluster of risk factors (RFs), which are not only associated with the development of cardiovascular (CV) disease (CVD), but also with increased all-cause mortality. In this review, we consider the importance of the circadian rhythm in the regulation of metabolic processes, the significance of circadian misalignment in the pathogenesis of MetS, and the management of MetS in relation to the cellular molecular clock

The effects of extreme low frequency pulsed electromagnetic field on bone mineral density and incidence of fractures in patients with end - stage renal disease on dialysis - three year follow up study

Background/Aim. A variety of physical therapy options has been developed for the treatment of musculoskeletal disorders including those characterized with low bone mineral density (BMD). Extreme low frequency pulsed electromagnetic field (ELF-PEMF) can accelerate bone formation. Patients with end stage of renal disease (ESRD) are predisposed to high incidence of fractures due to bone disorder with multifactorial pathogenesis. Vitamin D, calcium supplements, antiresorptive and anabolic drugs in those patients have changed pharmacodynamics and pharmacokinetics and have minimal or limited effects. The aim of this study was to assess the effectiveness of long-term ELF-PEMF therapy applied in concordance with physical exercise on bone mass, incidence of new bone fractures and parathyroid hormone concentrations in ESRD patients on dialysis. Methods. In this 3-year prospective clinical trial, 151 patients with ESRD on dialysis program were subjected to treatment with ELF-PEMF (18 Hz, 2 mT) applied during 40 min after 10 consecutive dialysis procedures, 4 times through one year (120 treatments in total during three years) together with kinesitherapy (study group) or only with kinesitherapy (control group) on the voluntary basis. Results. Total of 124 patients have completed the study. In the study group (n = 54), regardless of sex, significant improvements of BMD, T-score and Z-score on both lumbar spine and femoral neck were achieved after 3-year treatment with ELF-PEMF. In the control group (n = 70), significant decreases of BMD, T-score and Z-score as well as the higher incidence of new bone fractures were recorded. Conclusion. ELF-PEMF could be a convenient and safe non-pharmacological therapeutic strategy for fracture prevention in nephrology practices

Morphometric analysis of the fascicular organisation of the optic nerve

Background/Aim. The optic nerve is anatomically observed in four segments: intrabulbar, orbital, canalicular, and cranial. According to the literature, the surface of the transversal cut of the nerve is different through it. The aim of this study was to evaluate the fascicular organisation of the optic nerve, throughout its three segments from the eye. Methods. Five pairs of optic nerves, obtained from the autopsies were examined. Using Heidenhain's (azan) staining, the cuts were prepared for microscopy. Morphometric analysis was performed using the stereological methods for morphometric cytology - the Weible’s testing system M42. The following measures were established: the surface of the transverse cut of the nerve, the entire surface of fasciculi, the entire surface of connective tissue and blood vessels, the number of fasciculi, the surface of a single fasciculus. Results. The surface of the transverse cut of the nerve was found to grow from the orbital to the cranial segment, as well as the entire surface of fasciculi. While their number is significantly lower in the cranial segment, the number of fasciculi varied slightly between the orbital and the canalicular segment. The surface of a single fasciculus grows from the bulb to the chiasma. There is probable a cause to believe that this may be due to fusion of the “small” fasciculi in the orbitocranial direction. Conclusion. There are significant differences among the examined parameters of the different parts of the optic nerve
