This paper addresses the depolarisation effect in off-body body area networks channels, based on measurements performed at 2.45 GHz in an indoor environment. Seven different scenarios, involving both static and dynamic users, were considered, taking a statistical perspective. The analysis of the cross-polarisation discrimination is performed, as well as the analysis of path loss in co- and cross-polarised channels. Results show a strong dependence of the cross-polarisation discrimination and of channel characteristics on the polarisation and propagation condition, i.e. line-of-sight (LoS), non-LoS or quasi-LoS. Distance, varied between 1 and 6 m in the considered scenarios, is observed to have very little impact on the cross-polarisation discrimination. In the considered dynamic scenario, the channel is characterised by lognormal-distributed shadowing and Nakagami-distributed multipath fading. Parameters of the Nakagami distribution have essentially different values in the co- and cross-polarised channels, showing a trend towards Rice in the former and Rayleigh in the latter. Based on results, a model is proposed for a dynamic off-body channel.

When dealing with orthopaedic treatment of skeletal Class III malocclusion, a long-term stability of the treatment outcome is not always achievable. Although, clinical investigations1-4 have reported that orthopaedic treatments are effective to reduce skeletal Class III malocclusion avoiding surgery, there is a tendency for some patients toward re-emergence of the Class III growth pattern, especially during the pubertal growth phase.5 ABSTRACT

A great number of spring garlic populations are present in Serbia. It is a very heterogeneous biological material. To date, it has been little studied. Therefore, the aim was to study its production and chemical characteristics. Eighteen populations of spring garlic were examined. Most of the production of this garlic in Serbia is based on them. They were examined in Zminjak, which is located in the central Macva (Serbia). The method of field experiments was used. The research lasted for three years. The results comprise two groups of parameters. The first group contains the results which show the most important productive characteristics (weight of bulb, number of cloves per bulb, bulb yield). The second group consists of the parameters for chemical characteristics of the investigated populations (dry matter, etheric oil, and allin). In this case, the populations demonstrated a significant influence, and their stability was also very conspicuous. Most of the investigated populations of spring garlic can serve as a good resultant material for obtaining new cultivars. The populations can be classified as follows: SG-18, SG-25, SG-28, SG-16, SG-29 (yield), SG-21, SG-26 (technological quality) and SG-29, SG-18, SG-16 (foodstuff and pharmaceutical quality). They can remain as populations, but it would be significantly better to create new cultivars by using them.

Microscopic analysis of the skin and cuticle of wool fibers in Dubska pramenka show different qualitative parameters. The research study included different parts of the body and the samples of the wool fibers from different regions of the body. Histological description shows difference in the basic structurers of the skin in Dubska pramenka. A very pronounced thin epidermis, while dermis and hypodermis are more developed on the samples from the shoulder. Cornified flakes-cuticle of the root of the tail was of a fine structure, and cornified flakes from the rump showed the features of the rough wool fibers. “Transitional form of cuticle” was dominant on the shoulder. The qualitative parameters have a significant influence on the overall quality of wool in general, and the research contributes to a greater usability value of the wool and development of livestock farming in areas in a broader sense.

PURPOSE The aim of this study was to determine the prevalence of potentially inappropriate drug prescription (PIP) in older patients who were on chronic hemodialysis treatment and to explore the factors that lead to PIP. MATERIALS AND METHODS The study was performed at the Department of Nephrology, Clinical Center Niš, Serbia. It included patients who were 65 years old and older who suffered from the end-stage of kidney failure and were treated by hemodialysis. Univariate and subsequent multivariate logistic regression was used to analyze risk factors for PIP or omission (PPO) according to the STOPP and START criteria. RESULTS The study included 83 patients. According to the START criteria, PPO was found in 18 (22%) patients, and 32 (39%) patients experienced PIPs according to the STOPP criteria. The following factors were associated with PIP according to the START criteria: a number of comorbidities, reading the patient leaflet, and having the habit of drinking coffee. According to the STOPP criteria, polypharmacy was associated with PIP (OR = 1.287, p = 0.021): each additional drug increased the risk of potentially inadequate medications (PIM) by 28.7%. CONCLUSION Adequate consideration of potential risk factors, as well as the implementation of valid criteria for assessment of PIP, are just some of the measures that would contribute to solving complex therapeutic problems and designing strategies for rational prescribing according to the individual characteristics of patients.

Abstract Effects of additions of buckwheat flour and sourdough on the total phenols content, antioxidant activity, and sensory properties of crackers were examined. Different mixtures of wheat flour with addition of buckwheat flour and sourdough were used for the prepartion of crackers. Two types of lactic acid bacteria (Lactobacillus plantarum and Lactobacillus brevis) were used for the preparation of buckwheat sourdough. Properties of crackers made with addition of buckwheat flour and sourdough were analysed in comparison to control crackers made only with wheat flour. Significant increase of total phenols in comparison to wheat flour dough (0.73 mg gallic acid equivalent (GA)/g of dry basis (d.b.)) was accomplished by adding buckwheat flour (1.12 mg GA/g d.b.) and sourdough (1.77 and 1.79 mg GA/g d.b.) regardless of the type of lactic acid bacteries used. All samples showed the decrease in total phenol content during baking process. Crackers with sourdough had higher antioxidant activity (16.84 and 15.84 mmol Fe3+/g d.b.) compared to crackers made with addition of buckwheat flour (10.42 mmol Fe3+/g d.b.) and control sample (7.76 mmol Fe3+/g d.b.). The result of sensory analysis showed positive influence of sourdough on taste and texture of crackers and insignificant differences in odour and appearance of tested samples. Also, the chewiness of crackers made with the addition of buckwheat flour and sourdough was improved compared to control crackers made from wheat flour.

Introduction: Preterm delivery remains a burning issue all over the world, especially in Serbia because of the rate of negative natural increase. IL-6 can stimulate the release of prostaglandins and cause premature contractions and premature labor. Aim of the Study: The aim of this research is to examine the importance of infection in the occurrence of premature contractions and to examine whether the preterm labor is associated with increased concentrations of IL-6 in patients with intact fetal membranes. Patients and Methods: We examined 83 pregnant women. The age range was between 15 and 43 years. The experimental group had 53 pregnant women and a control group was consisted of 30 pregnant women. All pregnant women had singleton pregnancies. The age of pregnancy in both groups was between the 21st and 35th week of gestation. The experimental group was divided into three groups according to the localization of infection: bacterial vaginosis, an infection of the cervix and urinary tract infections. The laboratory identification of IL-6 was performed as a double sandwich ELISA method. The reagents used for the identification of IL-6 were manufactured by Beckman-Coulter and were strictly intended for the research. Results: There were 34 pregnant women or 64% with infection of the cervix, 26 pregnant women or 49% had a positive urine culture, while bacterial vaginosis was present in 47 pregnant women or 89%. A positive finding on all localization was found in 14 pregnant women or 26%. In the experimental group, IL-6 was detected in 37 pregnant women or 70%. The mean value of IL-6 proven in the experimental group was 20.6 pg/ml (SD=18.2, n=53). Conclusion: This research demonstrated a direct link between a bacterial infection and preterm delivery. IL-6 can be used as a serological marker of bacterial infection and preterm delivery.

Introduction: Malignant cells invasion of lymphatic drainage represents the basic precondition of metastasis and the disease progress. The invasion of tumor depends on its pathomorphologic characteristics, out of which one of the most significant role is the type. Aim of the Study: Descriptive analysis of operated patients, estimation of frequency and representativeness of the stated types of NSCLC in the monitored group, analysis of malignant cells of lung cancer in lymphatic drainage on the basis of the type of primary tumor. Patients and Methods: The study included 331 patients, who underwent the surgery during which the malignant infiltration was removed, in addition to the dissection of lymph nodes drainage. Results: Out of the total number of operated patients, 257 of them were male gender, while 74 were female gender, with the average age of 63.52 years (21-80). The relation of gender structure of the patients in relation to gender was statistically significant (p=0.00). The ratio between squamous cell carcinoma to adenocarcinoma was 182:140, while the other types of tumor were insignificant. Statistically, there was no significant difference in the frequency of two most common types of lung cancer (χ2test= 3.02; p=0.09). There was no statistically significant connection between the type of tumor and N1 metastasis (χ2=1.55; p=0.46), as well as in the ratio between the type of tumor and malignant infiltration of lymph nodes, level N2 (χ2=2.33; p=0.32). Conclusion: There is no connection between the type of lung cancer and invasion of levels N1 and N2 of lymph nodes.
