Invariant Submanifolds of Generalized Sasakian-Space-Forms

The object of this paper is to study the invariant submanifolds of generalized Sasakian-space-forms. Here, we obtain some equivalent conditions for an invariant submanifold of a generalized Sasakian-space-forms to be totally geodesic.Comment: 11 page

Chemical Composition and Nutritive Value of Oak (Quercus robur) Nut and Leaves

WOS: 000287570600023To determine the potential nutritive value of different parts of Quercus robur chemical composition and in vitro gas production technique were used. Crude protein, dry matter contents and gas production of kernel were higher (P<0.01) than the other parts of oak, whereas, CT, NDF and ADF contents were lower. The NDF and ADF contents of cup and hull were significantly higher compared to those of the other parts of oak. Oak nut and leaves have potential nutritive value for ruminant animals

Application of Dempster-Schafer Method in Family-Based Association Studies

In experiments designed for family-based association studies, methods such as transmission disequilibrium test require large number of trios to identify single-nucleotide polymorphisms associated with the disease. However, unavailability of a large number of trios is the Achilles' heel of many complex diseases, especially for late-onset diseases. In this paper, we propose a novel approach to this problem by means of the Dempster-Shafer method. The simulation studies show that the Dempster-Shafer method has a promising overall performance, in identifying single-nucleotide polymorphisms in the correct association class, as it has 90 percent accuracy even with 60 trio

Interpolation of Surfaces with Asymptotic Curves in Euclidean 3-Space

In this paper, we investigate the interpolation of surfaces which are obtained from an isoasymptotic curve in 3D-Euclidean space. We prove that there exists a unique C0-Hermite surface interpolation related to an isoasymptotic curve under some special conditions on the marching scale functions. Finally, we present some examples and plot their graphs

Dempster-Schafer Method in Family Based Association Studies

In experiments designed for family-based association studies, methods such as transmission disequilibrium test (TDT) require large number of trios to identify single nucleotide polymorphisms (SNPs) associated with the disease. However, unavailability of large number of trios is the Achilles' heel of many complex disease studies, especially for the late-onset diseases since parents might have passed away or unavailable. This problem motivated us to look for new approaches that require smaller number of trios to detect associations in family based studies. Aiming this, we propose using Dempster-Shafer method of evidence to detect the associations in family-based studies and show that this approach has a good performance in identifying associations with moderate to small sized samples

The frequency of buccopalpebral reflex in Parkinson disease

Background/aim: This study aimed to define the frequency of a primitive reflex, the buccopalpebral reflex (BPR), and its association with the clinical situation in patients with Parkinson disease. Materials and methods: Between May 2010 and May 2011, 222 patients, 115 with Parkinson disease and 107 patients without any sign of neurodegenerative disease, were included in the study. All included patients were examined for BPR and snout reflex and were also evaluated with the Mini Mental State Examination. All patients with Parkinson disease were classified with the Unified Parkinson's Disease Rating Scale (UPDRS) and the Hoehn and Yahr Score to determine their clinical severity. Results: Sixteen patients with Parkinson disease (13.9%) had a BPR (+) and 4 patients in the control group (3.7%) (P < 0.001). The UPDRS score, UPDRS daily life activities score, and UPDRS motor system score were all higher in the group with BPR (+). All patients with a BPR also had a positive snout reflex. Conclusion: BPR is more frequent in patients with Parkinson disease than in patients without a neurodegenerative disease

Conformal, concircular, quasi-conformal and conharmonic flatness on normal complex contact metric manifolds

Conformal, concircular, quasi-conformal and conharmonic curvature tensors play an important role in Riemannian geometry. In this paper, we study on normal complex contact metric manifolds under flatness conditions of these tensors

T2-weighted MRI in Parkinson's disease; Substantia-nigra pars compacta hypointensity correlates with the clinical scores

WOS: 000224716800006PubMed: 15472421Background: Iron accumulation in substantia nigra. pars compacta (SNpc) and related intensity and volumetric changes in patients with idiopathic Parkinson's disease (PD) has been reported previously. There are only a few studies evaluating the relation between neuroradiological findings and clinical scores, with contradictory results. Alms: In this study we aimed to measure the iron-rich brain areas of PD patients and healthy subjects with T2-weighted magnetic resonance imaging (MRI) and to evaluate the relation between the clinical scores of PD patients and these imaging results. Methods and Materials: T2-weighted MRI findings were studied in 20 patients with PD and 16 healthy controls. The width of SNpc, putamen volume, and the intensity of the basal ganglia were measured. Unified Parkinson's Disease Rating Scale (UPDRS) was used for evaluating the clinical status. Statistical Analyses: Mann Whitney U test for group comparisons, Wilcoxon sign rank test for comparisons within the patient group, and Spearman's rank correlation coefficient for analyses of correlations were used. Results: Mean SNpc and dentate nucleus intensities were lower in PD patients than healthy subjects. Mean SNpc width and putamen volumes were lower in patients. Decrease in the intensity of mean SNpc correlated with high UPDRS and rigidity scores. Conclusion: The results of our study reflect the increase in iron accumulation and oxidative stress in the SNpc in Parkinson's disease. The decrease in the intensity of SNpc correlates with poor clinical scores
