Abstract:The aim of the present study was to identify the mastitis-causing yeasts from quarters with subclinical mastitis and to evaluate the effect of the teat-end lesions on the outcome of mycotic mastitis. A cross-sectional study was conducted in 9 dairy herds located in Tiaret province, western Algeria. The clinical status of 752 quarters was determined by clinical examination and the California Mastitis Test (CMT). The teat-end condition was assessed visually and scored on a scale of 1 to 5, and the mastitis-causing yeasts were identified using API 20C AUX system. Mould identification at the genera level was based on the macroscopic and microscopic criteria. Out of 752 examined quarters, 261 (34.7%) quarters tested positive for CMT. Fungal agents were found in 5.75% of milk samples (15/261), with the predominance of Candida spp. The most frequent species was Candida tropicalis followed by C.albicans, Cryptococcus neoformans, Cryptococcus albidus, Geotrichum capitatum, Saccharomyces cerevisiae and Penicellium spp. The analysis of the data indicated no association between teat-end lesions and the prevalence of mycotic mastitis (Odds ratio (OR) = 1.047). The outcome of the present study pointed out the implementation of fungi in mastitis and consequently their influence on the milk’s microbiological quality.
Abstract:improve nursing practice, to provide more professional care, to increase their autonomy, nurses need to engage and utilize more and more evidence based practice. Although there is a consensus among healthcare providers, that the application of evidence-based practice is beneficial for both patients and health institutions, still now there are procrastinating and obstacles in the application of these practices in some health care facilities. Objectives: this study aims to assess the main challenges faces nurses to implement evidence-based nursing practices in three tertiary hospitals using a descriptive cross –section study design. Setting: This study was conducted at three governmental tertiary hospitals in Taif city –Saudi Arabia. Sampling: for this study the sample was taken from nurses working in these three hospitals by convenience sampling method. The results of this study showed that (55%) of nurses were not practicing evidence-based nursing practice (EBNP)N before. Moreover the findings of study revealed that subjects were had poor awareness about steps and resources of evidence based practice (EBP). Furthermore the most common barrier faced study nurses were insufficient time to find research reports (58%), lack of authority to change practice (66%), lack of supportive from colleagues (61.5%) and insufficient support from doctors.
Abstract:Identifying of anomalous observations has received a great deal of attention in the statistical literature in the context of ordinary least squares estimator (OLSE). However, the explanatory variables can be inter correlated with each other and alternatives to OLSE come out to address anomalous observations and multicollinearity, simultaneously. In this research paper, I use global influence technique to identify anomalous observations in modified Liu estimator (MLE) proposed by Li and Yang (2012). MLE is superior, in the mean square error matrix sense, to the OLSE, Liu estimator (LE), ridge regression estimator (RRE) and modified ridge regression estimator MRRE). When MLE is used to mitigate the effects of multicollinearity, the anomalous observations can be drastically modified. This paper is aimed to analyze global influence techniques to identify anomalous observations in MLE. To illustrate the methodologies derived in this paper two multicollinearity real data sets were used to identify anomalous observations using global influence techniques. Approximate case deletion influence measures are also proposed for the MLE
Abstract:Our study aims to show whether the administration of Fibroblast Growth Factor-2 (FGF2) and ozone against neuron-damaging hypoxia-ischemia has any neuroprotective effects in rats exposed to experimental cerebral ischemia-reperfusion. 6 groups were created with each group containing 10 rat that 7d old male Wistar rats. The first group, which was the Sham group, was the one in which a neck dissection was performed while ischemia was not caused. 2nd group, carotid arteries were linked, hypoxia was induced in order to cause hypoxia-ischemia (HI), which is done all groups except sham. The other groups were the ones with 10 µl/ml and 20 µl/ml FGF2 administered. The last groups were the ones with 25 ?g/ml and 50 ?g/ml ozone administered, routine tissue follow-up procedures were carried out and stained with hematoxylin and eosin stain, and inflammation, eosinophilic cytoplasm, edema in the cerebral cortex, vascular congestion and necrobiotic-necrotic changes were scored and evaluated. In light microscope revealed moderate-to-severe eosinophilic cytoplasm and necrobiotic changes in the HI group when compared to the Sham group and the 20 µl/ml FGF2 group among others. Significant differences in the criteria of inflammation, vascular congestion and edema in the cerebral cortex was detected between the same groups. Kruskal-Wallis test was used for intergroup comparison resulted in a statistically significant difference between all of the study groups (p< 0.05). In our study, morphological recovery was observed depending on the different doses of FGF2 and ozone used to protect the neurons, were fund to be statistically significant.
Abstract:The aim of this study was to investigate effect of the compressive follower preload on modal characteristics of the human whole lumbar spine. A computed tomography (CT)-based 3D ligamentous FE model of the human T12–pelvis spinal segment was developed and validated to predict lumbar modal responses in terms of resonant frequency and mode shape in vertical direction under different values of compressive follower preload. The results showed that under the 0 N, 400 N, 600 N and 800 N preloads, the vertical resonant frequencies for the T12–pelvis model were 6.49 Hz, 7.27 Hz, 7.55 Hz and 7.76 Hz respectively, which presented an increase with increasing preload magnitude. The mode shapes at these resonant frequencies illustrated that the lumbar spine not only performed vertical motion but anterior-posterior (A-P) motion and rotation under vertical vibration. Moreover, increasing the preload decreased vertical displacement of the vertebrae and also altered their A-P displacement and rotational angle in the sagittal plane for the vertical mode shape.
Abstract:Attention deficit hyperactivity disorder (ADHD) is a common disorder that affecting about 5-10% of school age children. A Sustained release methylphenidate (CONCERTA) is commonly used to treat such condition in children. It has a great efficacy in ADHD children. A lot of reports have documented the relationship between MPH and sleep bruxism. However, there is a paucity of reports in the literature that documented awake bruxism as a side effect of sustained release MPH. Up to our knowledge there is only one report of its kind showing such relationships. We report the case of a 10-year-old girl who presented with awake bruxism after her third dose of sustained release MPH. \nIt is a serious side effect of a sustained release methylphenidate (CONCERTA) that might affect health of oral cavity. So, it is important to pick it up early to prevent serious complication and improve quality of life for them.
Abstract:EOs has received attention in recent years as potential ‘natural’ alternatives for replacing antibiotic growth promoters due to their positive impact on growth performance. They were shown to have antimicrobial properties against different types of microorganisms including bacteria and fungi . Results from those studies revealed desirable effects of EO and their derivatives [2-3] for human. \nHowever paramecium sp were used to study environmental qualities and toxic effects of industrial, agricultural and domestic chemicals [4-5]. The objective of this study was to examine in vitro toxicity of essential oil (thymol) and to describe their specific effects on, the population growth, percentage of answer, Proportioning of protein and Proportioning of carbohydrate. \nResults showed that treatment affected the population growth, percentage of answer, Proportioning of protein and Proportioning of carbohydrate. Among the effects of thymol on the growth, we find that different doses have direct and rapid effects on the living organism development of Paramecium tetraurelia.
Abstract:This paper considers the somatic metaphors with various components, and their functions. The statistics has shown the most and the least frequent somatic elements both in Russian and German socio-political discourse.
Abstract:In Algeria, abortions represent a brake to the development of bovine breedings. For that we \npurpose an investigation on the prevalence of the main abortive agents as Neospora caninum and \nToxoplasma gondii to estimate the potential risk that represent the beef meat for the consumers. 5673 \nserums of cattle distributed in 29 departments of the country, was tested by the technique ELISA. A \nglobal prevalence of 84.30 % (77,8 - 90,8 %) for Toxoplasma gondii, and 58.68 % (50.7-68,2 %) for \nNeospora caninum was revealed. Our results also indicate seroprevalence in 28 bovine breedings on \n29 followed departments (the East, the West, Center and the South). Furthermore, Toxoplasma and \nNeospora circulates in the same bovine breedings of the departments of Ain Témouchent, Constantine, \nand Saïda
Abstract:Aim: This study aimed at analyzing the internal reliability of the Knowledge and Attitude Scale for Geriatric Functional Status Assessment which was developed for measuring the information and attitudes of primary care physicians in terms of geriatric functional status assessment.\n Method: The study participants were 41 physicians working in 19 Family Health Centers in Edirne city center between the dates of 15.09.2015-15.10.2015. Data was collected by using a scale which was prepared by our department by using the information in literature. The scale contained a total of 22 questions including 9 questions on socio-demographics and 13 questions in the form of 5-point Likert scale. Data was evaluated by using SPSS program, and Cronbach’s alpha reliability analysis was made.\n Results: Of the participating physicians, 28 were male (68.3%) and 13 were female (31.7%). Their average score was 24.32±11.50. We found a significant relation between physicians’ having training on functional status assessment and knowing how to make a geriatric functional status assessment (Pearson χ2=33.218; p<0.01). According to the reliability analysis of the 13-item scale, the Cronbach’s alpha value was 0.934. \n Conclusion: The scale’s reliability was proved for measuring the information and attitudes of primary care physicians in terms of geriatric functional status assessment in our country.
