Evaluation of the effect of Ramadan fasting on fat-soluble antioxidants and markers of oxidative stress in healthy Pakistani subjects

The aim of this study is to evaluate the effect of Ramadan fasting on the fat-soluble antioxidants [all-trans-retinol (vitamin A) and α-tocopherol (vitamin E)] in healthy Pakistani subjects. Thirty (30) healthy male volunteers (aged 30–50 years) with Ramadan fasting have participated in the study. Blood sampling from these subjects was conducted 1 day before and on 15th and 28th days of Ramadan. The serum levels of vitamin A and vitamin E were measured using liquid chromatography linked with UV–visible (HPLC–UV). The comparison between the samples taken at different times was made by Minitab software applying two samples and paired t-test at (p?<?0.05) as significant. No significant changes have been found in the levels of all-trans-retinol before and during Ramadan values. The levels of α-tocopherol on 28th Ramadan have been decreased significantly when compared with its values before Ramadan (p?<?0.0001). It is concluded that there is nonsignificant change in the levels of vitamin A during the month of Ramadan while the levels of α-tocopherol have been decreased significantly on the 28th day of Ramadan. It is therefore suggested that the fasting of Ramadan has effect on the levels of α-tocopherol and food-based interventions might be necessary to modify the diet during Ramadan.

树的罗马控制数和控制数

A Roman dominating function on a graph G = (V, E) is a function f : V→{0, 1, 2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) - 2. The weight of a Roman dominating function is the value (?). The minimum weight of a Roman dominating function on a graph G, denoted byγR(G), is called the Roman dominating number of G. In this paper, we will characterize a tree T withγR(T) =γ(T) 3.

A comparative study of magnetic resonance venography techniques for the evaluation of the internal jugular veins in multiple sclerosis patients

Background and Purpose

The use of magnetic resonance imaging (MRI) to assess the vascular nature of diseases such as multiple sclerosis (MS) is a growing field of research. This work reports on the application of MR angiographic (MRA) and venographic (MRV) techniques in assessing the extracranial vasculature in MS patients.

Materials and Methods

A standardized MRI protocol containing 2D TOF-MRV and dynamic 3D contrast-enhanced (CE) MRAV was run for 170 MS patients and 40 healthy controls (HC). The cross-sectional area (CSA) of the internal jugular veins (IJVs) was measured at three neck levels in all subjects for both MRV techniques to determine the presence of venous stenoses. All data were analyzed retrospectively.

Results

For the values where both methods showed signal, the 3D method showed larger CSA measurement values compared to 2D methods in both IJVs, in both MS and HC subjects which was confirmed with student paired t-tests. Of the 170 MS patients, 93 (55%) in CE-MRAV and 103 (61%) in TOF-MRV showed stenosis in at least one IJV. The corresponding numbers for the 40 HC subjects were 2 (5%) and 4 (10%), respectively. Carotid ectasias with IJV stenosis were seen in 26 cases (15%) with 3D CE-MRAV and were not observable with 2D TOF-MRV. Carotid ectasias were not seen in the HC group. In the 2D TOF-MRV data, banding of the IJVs related to slow flow was seen in 58 (34%) MS cases and in no HC cases. MS patients showed lower average CSAs than the HC subjects.

Conclusion

The 3D CE MRAV depicted the vascular anatomy more completely than the 2D TOF-MRV. However, the 3D CE MRAV does not provide any information about the flow characteristics which are indirectly available in the 2D TOF-MRV in those cases where there is slow flow.
