Objective To study the role of uterine artery notch on color Doppler ultrasound and roll over test in prediction of PIH. Methods 100 women with high risk pregnancies were studied for presence or absence of uterine artery diastolic notch by Doppler ultrasound at 16-28 weeks. Same women were then subjected to roll over test at 28-32 weeks. Results The primary outcome was that uterine diastolic notching alone and combined together with roll over test shows a high specificity (98.53%) for predicting PIH than roll over test (76.47%) alone. PPV of uterine artery diastolic notching (83.33%) was higher than roll over test alone (54.29%) and both tests combined together (80%). Conclusion After analyzing all the results, it has been concluded that uterine artery Doppler notching is better predictor for PIH than roll over test or even combined Doppler ? Roll over test together.Keywords Uterine artery notching Á Color Doppler Á Roll over test Á Pregnancy induced hypertension
Cataract is characterized partial or complete loss of transparency of the lens that leads to loss of vision. Globally, cataract associated blindness is a major cause of morbidity in developing countries. The cataractogenesis is affected by a number of factors with redox imbalance at the top of list. This imbalance results either from an increased generation of free radicals and/or decreased production of antioxidants. The end products of lipid peroxidation are both mutagenic and carcinogenic. One such product, malondialdehyde (MDA) reacts with deoxyadenosine and deoxyguanosine in DNA, to form DNA adducts. Its role in cataractogenesis is due to its cross linking ability. The present study analyzed the role of MDA in the development of senile cataract. Its level was measured in 75 randomly selected senile cataract patients of different age groups and matched against suitable controls. The study found statistically significant increased levels of MDA in cataract patients but not in controls, indicating an oxidative stress. The present study concluded that increased levels of MDA increased the susceptibility to cataractogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
