Principal Component Analysis of Gait Kinematics Data in Acute and Chronic Stroke Patients
Ivana Milovanovi ,Dejan B. Popovi
Computational and Mathematical Methods in Medicine , 2012, DOI: 10.1155/2012/649743
Abstract: We present the joint angles analysis by means of the principal component analysis (PCA). The data from twenty-seven acute and chronic hemiplegic patients were used and compared with data from five healthy subjects. The data were collected during walking along a 10-meter long path. The PCA was applied on a data set consisting of hip, knee, and ankle joint angles of the paretic and the nonparetic leg. The results point to significant differences in joint synergies between the acute and chronic hemiplegic patients that are not revealed when applying typical methods for gait assessment (clinical scores, gait speed, and gait symmetry). The results suggest that the PCA allows classification of the origin for the deficit in the gait when compared to healthy subjects; hence, the most appropriate treatment can be applied in the rehabilitation.

Journal of Automatic Control , 2009, DOI: 10.2298/jac0901013d
Abstract: We present a method for the synthesis of electrical stimulation profiles for assisting of the walking in hemiplegic individuals. The stimulation profiles are synthesized by combining the joint torques estimated from the simulation that optimizes the tracking errors with a constraint of the minimal coactivation of antagonist muscles and the recruitment of the muscles for the potential user. The predicted electrical stimulation profiles were compared with the EMG recordings of the prime movers of the leg joints. The conclusion is that synthesis of controls should rely on muscle activation profiles determined through simulation, in which the level of coactivation of antagonist muscles are preset to ensure stability of the joints and smooth movements. The example presented uses data from a healthy individual (model parameters), but the methodology is directly implantable for hemiplegic individual just by replacing the model parameters, the EMG and the trajectory of the nonparetic leg.

Abstract: Molds are ubiquitously distributed in nature and their spores can be found in the atmosphere even at high altitudes. The difficulty of controlling these undesirable molds, as well as the growing interest of the consumers in natural products, have been forcing the industry to find new alternatives for food preservation. The modern trends in nutrition suggest the limitation of synthetic food additives or substitution with natural ones. Aromatic herbs are probably the most important source of natural antimicrobial agents. Origanum heracleoticum L. essential oil has been known as an interesting source of antimicrobial compounds to be applied in food preservation. In the this work, we have investigated the effect of essential oil obtained from O. heracleoticum on growth of six isolates of Penicillium aurantiogriseum and four isolates of Penicillium chrysogenum isolated from meat plant for traditional Petrovacka sausage (Petrovská klobása) production. The findings reveal that the essential oil of O. heracleoticum provides inhibition of all of fungal isolates tested. O. heracleoticum L. essential oil exhibited higher antifungal activity against the isolates of P. chrysogenum than the isolates of P. aurantiogriseum. O. heracleoticum essential oil showed a MIC value ranging from 25 to 100 μL/mL. The fungi cultivated in the medium with higher concentration of essential oil showed certain morphological changes. The alterations included lack of sporulation and loss of pigmentation.

Abstract: host lipids have been implicated in the pathogenesis of toxoplasma gondiiinfection. to determine if toxoplasmainfection influences the lipid status in the normal host, we assessed serum lipids of swiss-webster mice during infection with the bgd-1 strain (type-2) at a series of time points. mice were bled at days zero and 42 post-infection, and subgroups were additionally bled on alternating weeks (model 1), or sacrificed at days zero, 14 and 42 (model 2) for the measurement of total cholesterol (chl), high density lipoproteins (hdl), low density lipoproteins (ldl) and triglycerides and adiponectin. at day 42, brains were harvested for cyst enumeration. a significant decrease (p = 0.02) in hdl and total chl was first noted in infected vs. control mice at day 14 and persisted to day 42 (p = 0.013). conversely, ldl was unaltered until day 42, when it increased (p = 0.043). serum ldl levels at day 42 correlated only with cyst counts of above 300 (found in 44% mice), while the change in hdl between days zero and 42 correlated with both the overall mean cyst count (p = 0.041) and cyst counts above 300 (p = 0.044). calculated per cyst, this decrease in hdl in individual animals ranged from 0.1-17 μmol/l, with a mean of 2.43 ± 4.14 μmol/l. serum adiponectin levels remained similar between infected and control mice throughout the experiment.

Abstract: Timely identification of excessive alcohol use and its potential complications is a prerequisite for successful treatment. Several routine tests have been used in laboratories that may help in diagnosing alcoholism, such as determination of MCV, AST, ALT, GGT, but it has been shown that they lack specificity and sensitivity. Contemporary bio-markers are increasingly being used today that may due to their unique characteristics help in discovering the onset of chronic alcohol abuse, as well as in abstinence and relapse monitoring. The term carbohydrate-deficient transferrin (CDT) stands for a small group of human transferrin isoforms (asialo, monosialo, and disialotran sferrin) with a lower degree of glycosylation in comparison to the dominant transferrin isoform (tetrasialotransferrin). Persons consuming large quantities of alcohol (≥50-80 g daily) over a period of at least two weeks have increased concentrations of transferrin isoforms lacking one (disialotransferrin) or both (asialotransferrin) carbohydrate chains. In this paper the traditional markers of chronic alcohol abuse (GGT, AST, ALT, and MCV) were determined, as well as the new biomarker CDT, after which diagnostic evaluation was performed and their usability and clinical value in routine laboratory practice were estimated. These markers were also determined in heavy alcoholics on admission into hospital and after two weeks of therapy, with the aim of estimating their diagnostic value for abstinence and relapse monitoring.

Abstract: Introduction. Hormonal treatment of prostate cancer (CaP) in the form of total androgen blockade (TAB) with or without radiotherapy is applied in metastatic disease and in patients with nonmetastatic and localized disease as well. Objective. The aim of the study was to compare oncological results, residual and newly developed symptoms during treatment and the quality of life in patients with nonmetastatic CaP treated by using Tand in a group treated both with Tand radiotherapy (RT+TAB). Methods. Retrospective analysis of 126 patients with nonmetastatic CaP was performed. Follow-up was 36 months. Seventynine out of 126 patients were treated with Talone and 47 with Tand radiotherapy (TAB+RT). Overall survival, metabolic syndrome appearance and the frequency of nonmalignant complications during treatment were analyzed. Urinary, digestive and sexual symptoms were analyzed, as well as the overall health condition of the patients. Results. Fatal outcome and/or disease progression occurred in 29 out of 126 patients (23%). High risk patients were significantly more frequent in the TAB+RT group (p=0.04). Mortality rate was not different in both groups indicating that better results of treatment were achieved in patients treated with TAB+RT. Metabolic syndrome appeared in 51.6% of Tpatients and in 51.1 of TAB+RT patients, and was significantly more frequent at the end of the follow-up than at the beginning of the treatment (p=0.003 in Tand p=0.01 in TAB+RT group). Urinary symptoms were more frequent than digestive symptoms in both groups. The quality of life was slightly improved after the beginning of therapy to be followed by the tendency of gradual decrease. Conclusion. Both modalities of treatment were efficient. Therapy TAB+RT was more efficient in high risk patients. Metabolic syndrome was more frequent after a long-term administration of therapy than at the beginning. The quality of life was the most affected in sexually active patients.
The crime of aggression between consensus and contestation

Medjunarodni Problemi , 2011, DOI: 10.2298/medjp1101024m
Abstract: The efforts to define the crime of aggression as an international crime are accompanied by many problems. Some countries see it as a sign of salvation against foreign interference in internal affairs, while others see it as a limiting factor in achieving their own interests. In the battle between consensus and contestation every victory was a Pyrrhic one and the price of any compromise was high. However, after the Review Conference of the Rome Statute of the International Criminal Court, which was held in 2010, we have many reasons for optimism. In this paper, the author presents the historical development of the crime of aggression from the theoretical discussion to its criminalization as an international crime. It is through a critical analysis of the norms in international documents and judgments of international courts based on them that we point to all the advantages and disadvantages of defining aggression. In his conclusion, the author predicts the future of the crime of aggression, bearing in mind the latest solutions in theory and practice of international criminal law.

Abstract: In the inter-census period, the process of ageing of the population of Vojvodina continued, and Vojvodina is in the stage of a deep demographic old age. The average age increased from 37,7 to 39,8 years, and the index of ageing from 71,0 to 94,1. Territorially speaking, the population of Vojvodina has a homogeneous age structure. All counties are in the stage of a deep demographic old age. Somewhat more favourable age structure is present in the South-Ba ki, Sremski and South- Banatski counties. Homogeneity is also present at the municipal level. Out of 45 municipalities, 39 belong to the phase of a deep demographic old age, 5 to a demographic old age, and 1 to the deepest demographic old age, while in the 1991 census 38 municipalities belonged to the phase of a demographic old age, and 7 to the phase of a deep demographic old age.
