On a perfect fluid Kahler spacetime

The object of the present paper is to study a perfect fluid K¨ahlerspacetime. A perfect fluid K¨ahler spacetime satisfying the Einstein field equation with a cosmological term has been studied and the existence of killingand conformal killing vectors have been discussed. Certain results related to sectional curvature for pseudo projectively flat perfect fluid K¨ahler spacetime have been obtained. Dust model for perfect fluid K¨ahler spacetime has also been studied

Centile values for serum lipids and blood pressure for Asian Indian adolescents

BACKGROUND: Reference data for plasma lipids and blood pressure are not available for Asian Indian adolescents. This study aimed to develop representative age- and sex- specific percentile reference data for serum lipids [total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-HDL cholesterol] and blood pressure for urban Asian Indian adolescents aged 14–18 years. The sample consisted of 680 boys and 521 girls aged 14–18 years from the cross-sectional population survey, Epidemiological Study of Adolescents and Young Adults (ESAY) for whom the data for serum lipid levels and blood pressure were recorded. Smoothed age- and sex- specific 5(th), 10(th), 25(th), 50(th), 75(th), 85(th), 90(th )and 95(th )percentiles where derived using LMS regression. RESULTS: Percentile-based reference data for serum lipids and blood pressure are presented for adolescent Asian Indian boys and girls for the first time. Asian Indian adolescents had lower levels of serum TC, LDL-C and HDL-C and higher TG than their counterparts in the USA. Interesting trends in TC and HDL-C levels where observed, which might reflect changes in dietary pattern and physical activity in this age group in India. CONCLUSION: These reference data could be used to identify adolescents with an elevated risk of developing dyslipidemia, hypertension and cardiovascular disorders, to plan and implement preventive policies, and to study temporal trends

Alzheimer's and non-Alzheimer's dementia: a critical review of pharmacological and nonpharmacological strategies

Objective. Dementia is an age-related progressive neurodegenerative disorder afflicting about 5% of the world's population, and it is expected to grow dramatically in the future keeping in view our ageing society. Currently available medications appear to be able to produce moderate symptomatic benefits but do not to stop disease progression. In this article, the management of the disorder, including the currently available drugs as well as psychosocial strategies, is discussed. Methods. A computerized search on Pubmed from 1980 to 2006 was carried out and all articles evaluated and graded on NICE guidelines. Results and conclusions. Currently evaluated and accepted medications only bring about a reduction in the deteriorating course. A combination of pharmacotherapy and psychosocial management is the need of the hour

The burden of behavioral emergencies: need for specialist emergency services

Behavioral emergencies constitute an important component of medical emergencies. Psychiatric emergency services, which handle the bulk of behavioral emergencies, are inadequate to meet the burden. Strategies to deal with them are also hampered by the lack of adequate research and availability of data. Since behavioral emergencies may present differently in different groups, requiring differing management, consensus guidelines need to be arrived at for tackling behavioral emergencies. In addition, training professionals for psychiatric emergency services should form a part and parcel of emergency management services

Role coloring bipartite graphs

A k-role coloring of a graph G is an assignment of colors to the vertices of G such that every color is used at least once and if any two vertices are assigned the same color, then their neighborhood are assigned the same set of colors. By definition, every graph on n vertices admits an n-role coloring. While for every graph on n vertices, it is trivial to decide if it admits a 1-role coloring, determining whether a graph admits a k-role coloring is a notoriously hard problem for k greater than or equal to 2. In fact, it is known that k-Role coloring is NP-complete for k at least 2 on general graph class. There has been extensive research on the complexity of k-role coloring on various hereditary graph classes. Furthering this direction of research, we show that k-Role coloring is NP-complete on bipartite graphs for k at least 3 (while it is trivial for k=2). We complement the hardness result by characterizing 3-role colorable bipartite chain graphs, leading to a polynomial time algorithm for 3-Role coloring for this class of graphs. We further show that 2-Role coloring is NP-complete for graphs that are d vertices or edges away from the class of bipartite graphs, even when d=1

Quasi-conformally flat and projectively flat trans-Sasakian manifolds

The object of the present paper is to study quasi-conformally flat and projectively flat contact manifolds. We have also studied Quasi-conformally flat and projectively flat trans-Sasakian manifolds. We obtained condition for trans-Sasakian manifold to be quasi-conformally flat and projectively flat. The value of scalar curvature has been obtained in quasi-conformally flat and projectively flat trans-Sasakian manifolds

DexmedetomidineVersus Clonidine as Adjuvant in Subarachnoid Block in Patients of Preeclampsia Undergoing LSCS.

Background: The aim of this study is to compare the duration and quality of analgesia with maternal and neonatal outcome following subarachnoid block with intrathecal hyperbaric bupivacaine with either dexmedetomidine or clonidine used as adjuvant in preeclampsia patients undergoing LSCS.Material and Methods: Patients with preeclampsia were drawn from those scheduled for operations requiring subarachnoid block for LSCS.100 ASA grade I & II patients are randomized into two groups.Group A:-Sub arachnoid block with [ 2ml 0.5% Bupivacaine heavy + 45 μg clonidine]Group B:-Subarachnoid block with[ 2ml 0.5% Bupivacaine heavy + 15μg dexmedetomidine]Results: Changes observed in systolic, diastolic and mean blood pressure were comparable in both the groups at different time points (P>0.05). Three patients in Group A and in Group B developed hypotension which responded to intravenous fluid therapy.SpO2 remained stable and comparable in both the groups throughout the study period, (P>0.05).There was significant prolongation of analgesia in Group B where first rescue analgesic was required after 9 hours of subarachnoid blockade. Patients in Group A required rescue analgesic at 7 hours after subarachnoid blockade.There was statistically significant difference in duration of analgesia in two groups. Postoperative analgesia was significantly prolonged in Group B as compared to Group A.Conclusion: Clonidine and Dexmedetomidine as an adjuvant to Bupivacaine did not show significant difference in onset and peak of sensory blockade but Dexmedetomidine provided prolonged duration of sensory blockade and postoperative analgesia as compared to Clonidine group
