DATA MINING LANGUAGES STANDARDS

The increasing of the database dimension creates many problems, especially when we need to access, use and analyze data. The data overflow phenomenon in database environments imposes the application of different data mining methods, in order to find relevant information from large databases. A lot of data mining tools emerged in the last years. The standardization of data mining languages become in the last years a very important topic. The paper presents Predictive Model Markup Language (PMML) standards from the Data Mining Group. PMML, a standard language for defining data mining models, which allows users to develop models within one vendor's application, and use other vendors' applications to visualize, analyze, evaluate or otherwise use the models.

An Ontological-based Model for Competences in Sustainable Development Projects: a Case Study for Project’s Commercial Activities

The paper presents a project management competencies model, using an ontological approach. The ontology, named PMCatalog, was developed in the framework of the project CONTO, financed by Romanian through the grant 91-037/2007. PMCatalog is consistent with the competence definition and PM competence elements included in the International Competence Baseline, the competency standard of the International Project Management Association. The main PMCatalog’s use cases for commercial activities in sustainable development projects are described. Ontology was developed using the Protégé editor.competence, project management, sustainable development, commercial activities

Tulathromycin disturbs blood oxidative and coagulation status

The aim of this study was to determine the effect of tulathromycin on serum oxidative status and coagulation factors in rabbits. Tulathromycin was administered to eight rabbits, and blood samples were obtained 0, 1, 5, 10 and 15 days after treatment. Indicators of serum oxidative status (malondialdehyde, nitric oxide, superoxide dismutase, retinol and -carotene) and coagulation values (antithrombin III, fibrinogen) were measured after tulathromycin treatment. In addition, routine serum biochemical values (creatine kinase-MB, lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, creatinine, blood urea nitrogen, cholesterol, triglyceride, high density lipoprotein, amylase, total protein, albumin, glucose and calcium), haemacell counts (white and red blood cells) and arterial blood gas parameters (packed cell volume, hemoglobin, pH, partial pressure of carbon dioxide, partial pressure of oxygen, actual bicarbonate, standard bicarbonate, total carbon dioxide, base excess in vivo, base excess in vitro, oxygen saturation, sodium and potassium) were also determined. Tulathromycin increased (P < 0.05) the levels of malondialdehyde, nitric oxide and superoxide dismutase activity, and decreased (P < 0.05) the level of antithrombin III. In conclusion, tulathromycin may cause oxidative damage and coagulation disorders during the treatment period.Key words: Tulathromycin, oxidative damage, coagulation disorder

Genetic PI based model and path tracking control of four traction electrical vehicle

Modeling and control of four-wheel electric vehicles are difficult due to their dynamic parameters and variable road conditions. In this paper, a robust and adaptive electric vehicle model and position control that can be adapted to state variables using a dynamic lateral and longitudinal model of a four-wheel electric vehicle have been proposed. The longitudinal and lateral forces have been modeled according to Newton's second law, depending on the parameters such as the vehicle's size, width, height, weight and slope angle by using dynamic equations of the vehicle. In this paper, a permanent magnet synchronous hub motor has been used for each wheel of the electric vehicle. The magic formula wheel model has been used to determine the relationship between the slip and the friction of the designed vehicle. Using the slip system, the relationship between the speed of the electric vehicle itself and the wheel speeds have been defined. The proportional controller at the position loop and proportional + integral controller at the speed loop of the designed system have been used. In the path tracking control system, position controls have been made in the X and Y coordinate planes. A P position controller and a PI speed controller have been used for each plane. Thus, there are 6 controller coefficients in total. Because of the complicated structure of the system, it is difficult to determine the most suitable controller coefficients by analytical methods. Therefore, the genetic algorithm which is one of the heuristic algorithms has been used in determining these coefficients. Simulation studies have been conducted with a different path and position references to see the effectiveness of the proposed electric vehicle model and position control. The obtained results show that the proposed model and control system are robust, effective and reliable.WOS:0005347255000012-s2.0-8508529761

Tulathromycin disturbs blood oxidative and coagulation status

The aim of this study was to determine the effect of tulathromycin on serum oxidative status and coagulation factors in rabbits. Tulathromycin was administered to eight rabbits, and blood samples were obtained 0, 1, 5, 10 and 15 days after treatment. Indicators of serum oxidative status (malondialdehyde, nitric oxide, superoxide dismutase, retinol and β-carotene) and coagulation values (antithrombin III, fibrinogen) were measured after tulathromycin treatment. In addition, routine serum biochemical values (creatine kinase-MB, lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, creatinine, blood urea nitrogen, cholesterol, triglyceride, high density lipoprotein, amylase, total protein, albumin, glucose and calcium), haemacell counts (white and red blood cells) and arterial blood gas parameters (packed cell volume, hemoglobin, pH, partial pressure of carbon dioxide, partial pressure of oxygen, actual bicarbonate, standard bicarbonate, total carbon dioxide, base excess in vivo, base excess in vitro, oxygen saturation, sodium and potassium) were also determined. Tulathromycin increased (P < 0.05) the levels of malondialdehyde, nitric oxide and superoxide dismutase activity, and decreased (P < 0.05) the level of antithrombin III. In conclusion, tulathromycin may cause oxidative damage and coagulation disorders during the treatment period. © 2011 Academic Journals

Evaluation of mean platelet volume and platelet count in patients with schizophrenia

Introduction: Compared to the general population, cardiovascular diseases are more common in schizophrenia patients and the mortality rate is higher than the general population. One of the explanations for increased cardiovascular events in patients with schizophrenia is the increase in platelet activity. Platelets are essential for progression of atherosclerotic lesions, plaque destabilization, and thrombus formation. Mean platelet volume (MPV) is a measure of platelet size and a good marker of platelet function and activation, which increases in cardiovascular diseases. MPV is routinely reported during complete blood count analysis. The aim of the present study was to evaluate MPV values of patients with schizophrenia. Methods: In this retrospective study, hospital-records of the patients who were consecutively admitted to psychiatry inpatient clinic between January 2015 and January 2017 with the diagnosis of schizophrenia were reviewed. Healthy subjects with no personal history of psychiatric disorder were included as a control group.  Results: A total of 100 (59 female, 41 male) schizophrenic patients who had been consecutively admitted to the psychiatry inpatient clinic and 37 (20 female, 17 male) healthy controls were included in this retrospective study. There were no significant differences between the patient group and control group in the terms of age (mean age patient group vs control group: 37.72 vs 35.03, p=0.081) and sex (p=0.603). Body mass index (BMI) was found to be significantly different between groups, higher in the patient group (p=0.001). The MPV was found to be significantly higher in patient group compared with the control group (MPV, patient group vs control group: 10.34 fL vs 9.97 fL, p=0.041). Platelet count (PC) was significantly lower in the patient group (PC, patient group vs control group: 234.36 vs 267.38, p=0.008) There was no correlation between MPV and BMI (p=0.354, r=0.10), and duration of illness (p=0.530, r=0.06).  Conclusions: As a result, increased MPV and decreased PC were found in a group of schizophrenic patient in this study. Since increased MPV and decreased PC are evaluated as risk factors for cardiovascular diseases in the general population, they can also be considered as a predictor of risk factors for cardiovascular diseases that are more frequently encountered in schizophrenia

ASSESSMENT OF THE CARDIOTOXICITY OF TULATHROMYCIN IN RABBITS

The aim of this study was to determine the cardiotoxic potency of tulathromycin. Tulathromycin (10 mg/kg, SC) was administered to ten adult male rabbits, and blood samples were obtained before and after drug administration (0 and 6 hours). Serum cardiac damage markers (troponin I, creatine kinase-MB, myoglobin, lactate dehydrogenase, aspartate aminotransferase), routine serum biochemical values (alkaline phosphatase, alanine aminotransferase, gammaglutamyltransferase, creatinine, blood urea nitrogen, cholesterol, triglyceride, high-density lipoprotein, amylase, total protein, albumin, glucose, calcium, ionised calcium, sodium, potassium), white blood cell (WBC) and red blood cell (RBC) counts, arterial blood gas parameters (pH, partial carbon dioxide pressure, partial oxygen pressure, actual bicarbonate, standard bicarbonate, total carbon dioxide, base excess in vivo, base excess in vitro, oxygen saturation, packed cell volume, haemoglobin) and serum oxidative status (malondialdehyde, nitric oxide, superoxide dismutase, retinol, beta-carotene) were measured. Increased levels of troponin I, creatine kinase-MB and creatinine, and decreased WBC counts, ionised calcium and potassium levels were observed after drug administration. Tulathromycin treatment may cause cardiotoxicity, but its effects may be less dramatic than those of other macrolide antibiotics frequently used in veterinary medicine

EFFECTS OF TYLOSIN ON SERUM CYTOKINE LEVELS IN HEALTHY AND LIPOPOLYSACCHARIDE-TREATED MICE

The effects of different doses of tylosin on serum cytokine concentrations were investigated in healthy and lipopolysaccharide-treated mice. The mice were divided into seven groups. Lipopolysaccharide (LPS) was injected into the positive control group. The other six groups received three different tylosin doses concurrently without or with LPS: 10 mg/kg, 100 mg/kg, 500 mg/kg, 10 mg/kg + LPS, 100 mg/kg + LPS and 500 mg/kg + LPS. After treatment, serum samples were collected at 0, 1, 2, 3, 6, 12 and 24 hours. Serum tumour necrosis factor alpha (TNF alpha), interleukin 1 beta (IL1 beta) and IL10 levels were determined by enzyme-linked immunosorbent assay (ELISA). Tylosin doses of 10 and 100 mg/kg induced no cytokine production in the healthy mice. Tylosin at 500 mg/kg had no effect on TNF alpha or IL1 beta production, but it induced IL10 production in healthy mice. All doses of tylosin reduced the elevated TNF alpha and IL1 beta in LPS-treated mice but increased their IL10 levels. In conclusion, these data suggest that tylosin has an immunomodulatory effect at the dose recommended for use against infection
