Background: Type 2 diabetes mellitus (T2DM) and its consequences are a serious global public health issue. By 2030, the number of people with type is predicted to reach 439 million. The purpose this study evaluate plasma levels glucose, HbA1c, insulin, lipid profile in Sudanese T2DM patients. Methods:...

introduction as functional magnetic resonance imaging (fmri) is too expensive and time consuming, its frequent implementation is difficult. the aim of this study is to evaluate repeatability of detecting visual cortex activity in fmri. materials and methods in this study, 15 normal volunteers (10 female, 5 male; mean age±sd: 24.7±3.8 years) attended. functional magnetic resonance images were ob...

In this study, we will show in three visual experiments that there are several brain regions in which induced blood oxygenation level-dependent (BOLD) responses are reproducible between visual tasks and between individual subjects. The reproducible BOLD responses indicate that the specific-sensorial structure (e.g., the lingual gyrus) and non-specific structure (e.g., the precuneus) both exhibi...

Age-related performance declines in visual tasks have been attributed to reductions in processing efficiency. The neural basis of these declines has been explored by comparing the blood-oxygen-level-dependent (BOLD) index of neural activity in older and younger adults during visual task performance. However, neural activity is one of many factors that change with age and lead to BOLD signal dif...

Blood-oxygen-level-dependent contrast functional magnetic resonance imaging (BOLD-fMRI) has been used to perform functional imaging in brain disorders such as stroke and brain tumors. However, recent studies have revealed that BOLD-fMRI does not image activation areas correctly in such patients. To clarify the characteristics of the evoked cerebral blood oxygenation (CBO) changes occurring in s...

PURPOSE Determine whether white matter signal fluctuation on T2* weighted BOLD contrast images are associated with aging and cerebral small vessel disease (SVD). METHODOLOGY Resting state BOLD data were collected with a 250 ms repetition time (TR) to achieve unaliased, ungated cardiac sampled BOLD (cs-BOLD) images on 11 young adult controls, 10 healthy older adult controls and 7 adults with e...

PURPOSE To computationally separate dynamic brain functional BOLD responses from static background in a brain functional activity for forward fMRI signal analysis and inverse mapping. METHODS A brain functional activity is represented in terms of magnetic source by a perturbation model: χ = χ0 +δχ, with δχ for BOLD magnetic perturbations and χ0 for background. A brain fMRI experiment produces...

Background Broiler chickens have properties as meat-producing poultry and produce meat with soft fiber quality. Broiler’s embryo needs to be given attention, especially against disease. The purpose of the study was observe trend research topic external factors which could affect embryo’s growth broiler. Method<ns4:b...
