Central Density Dependent Anisotropic Compact Stars

Stars can be treated as self-gravitating fluid. In this connection, we propose a model for an anisotropic star under the relativistic framework of Krori-Barua (1975) spacetime. It is shown that the solutions are regular and singularity free. The uniqueness of the model is that interior physical properties of the star solely depend on the central density of the matter distribution

Enteric Encephalopathy associated with reversible ECG changes: A Diagnostic Dilemma

Enteric fever is common in India. It presents with various clinical manifestations. Encephalopathyand ECG changes are indicators of prognosis. Persistent ECG changes indicate a poor prognosis. Thepathogenesis of encephalopathy is unclear though prostaglandins and free oxygen species may beimplicated in the prognosis and justifies the use of steroids in enteric encephalopathy withantibiotics. The case presented here presented with encephalopathy and ECG changes whichreversed following antibiotic and steroid therapy. The importance of the case lies in the fact thattyphoid should not be missed in the diagnosis of encephalopathy and ECG should be done in allcases of enteric fever to determine the prognosis

Study on Sedation with Local Analgesia in Calves

Abstract. The effect of sedatives and analgesics on heart rate, respiration rate and rectal temperature were observed. Heart rate and respiration rate significantly decreased during sedation with xylazine hydrochloride plus 2% lignocaine hydrochloride or 0.5% bupivacaine hydrochloride. A significantly decreased heart rate and respiration rate also found during sedation with diazepam plus 2% lignocaine hydrochloride or 0.5% bupivacaine hydrochloride. Two percent lignocaine hydrochloride showed short onset, rapid spreading and no side effect. Duration of analgesia was longer with 0.5 % bupivacaine hydrochloride (55.88±1.58 min in Group B and 48±11.25 min in Group D) compared to 2% lignocaine hydrochloride (39.60±5.77 min in Group A and 43.6±5.81 min in Group C). Xylazine hydrochloride showed short onset and long duration of sedation compared to diazepam. So for herniorraphy, xylazine hydrochloride can be used as a better sedative while 0.5 % bupivacaine hydrochloride can be used as a local analgesic for longer duration of action.Key Words: lignocaine hydrochloride, sedation, analgesiaNC Sarker et al/Animal Production 13(3):191-197 (2011

To Study Correlation of Body Fat and Blood Lipids with Autonomic Nervous System Activity in Postmenopausal Indian Women

Background: Obesity, physical inactivity, and altered estrogen metabolism play integrated role contributing to the disease risk profiles of postmenopausal women (PMW). Aim: To study the correlation of body fat and blood lipids with autonomic nervous system activity in PM Indian women. Subjects and Methods: A total of 60 PM sedentary women without any gross systemic disease were selected as a control group and 23 PMW, who were regularly doing morning walk for 1‑year was  selected as a study group. Body mass index (BMI), waist/hip (W/H) ratio were recorded; lipid profile analyzed, and conventional autonomic function tests were carried. Results were analyzed using SPSS version 16. Results: There was a significant difference in BMI, W/H ratio, lipid profile, autonomic function tests between the two groups. Aging and menopausal duration (MD) were positively correlated with pulse rate, systolic blood pressure, total cholesterol (TC), low‑density lipoprotein (LDL) cholesterol, orthostatic tolerance test (OTT), and negatively correlated with Valsalva ratio (VR), deep breath test (DBT), 30:15 relative risk (RR) intervals ratio, isometric hand‑grip test (HGT), cold pressor test (CPT). BMI and W/H ratio were positively correlated with TC, triglyceride, LDL cholesterol, OTT, and negatively correlated with isometric HGT, CPT. TC and LDL were negatively correlated with VR, deep breath difference test, 30:15 RR interval ratios, isometric HGT, CPT, and positively correlated with OTT. Multiple regression analysis revealed LDL cholesterol as the only significant independent explanatory variable of DBT. LDL cholesterol and age were the significant independent explanatory variables of  30:15 RR interval ratios, CPT. TC, LDL cholesterol, and age were the significant independent  explanatory variables of isometric HGT.Conclusions: Aging, MD, BMI, and W/H ratio all contribute significantly to worsening of autonomic functions and lipid profile. Multiple regression analysis revealed LDL cholesterol as the most significant contributor of worsening of autonomic functions in PM females and regular exercise can improve theseparameters significantly.KEY WORDS: Autonomic functions, blood lipids, body fat, menopaus

Charged gravastars admitting conformal motion

We propose a new model of a {\it gravastar} admitting conformal motion. While retaining the framework of the Mazur-Mottola model, the gravastar is assumed to be internally charged, with an exterior defined by a Reissner-Nordstr{\"o}m rather than a Schwarzschild line element. The solutions obtained involve (i) the interior region, (ii) the shell, and (iii) the exterior region of the sphere. Of these three cases the first case is of primary interest since the total gravitational mass vanishes for vanishing charge and turns the total gravitational mass into an {\it electromagnetic mass} under certain conditions. This suggests that the interior de Sitter vacuum of a charged gravastar is essentially an electromagnetic mass model that must generate the gravitational mass. We have also analyzed various other aspects such as the stress energy tensor in the thin shell and the entropy of the system.Comment: Minor addition, Accepted in Phys. Lett.

Parasitic Hypoproteinemia :A Diagnostic Dilemma in an Immuno competent Patient

Strongyloidiasis is caused by a nematode helminth which causes multisystem involvement with signs and symptoms related to gastrointestinal,pulmonary, dermatological and nervous system.The  index case discussed here presented with edema, hypoalbuminemia, malnutrition and anemia with urease positive duodenal ulcer.Duodenal biopsy suggested malabsorption and strongyloidiasis was detected in biopsy which clinched the diagnosis and treatment was given with ivermectin after which patient improved and responded to treatment.The importance lies in the fact that parasitic infections may cause malabsorption even in immunocompetent patients which is a rare entity, but must not be missed as it responds to treatment promptly which is cheap and effective

Accretion Disks Around Black Holes: Twenty Five Years Later

We study the progress of the theory of accretion disks around black holes in last twenty five years and explain why advective disks are the best bet in explaining varied stationary and non-stationary observations from black hole candidates. We show also that the recently proposed advection dominated flows are incorrect.Comment: 30 Latex pages including figures. Kluwer Style files included.

Effect of Progressive Muscle Relaxation on the Adverse Cardiovascular Profile in Women with Polycystic Ovarian Syndrome

Background: The altered stress reactivity in polycystic ovarian syndrome (PCOS) may constitute a link between depression, overweight, and cardiovascular risk factors. Aims: To study the effects of progressive muscle relaxation (PMR) on the stress levels of PCOS patients and their influence on the cardiovascular risk factors. Subjects and Methods: This prospective pilot project was conducted on 100 PCOS patients in a tertiary care hospital of West Bengal, after receiving approval from the Institutional Ethical Committee and informed consent of the subjects. The stress levels were assessed and conventional autonomic function tests and the lipid profi les were analyzed. The subjects were divided into two groups using an online randomizer. One group received medication, while the other group received medication and practiced progressive muscle relaxation (PMR) for three months. All parameters were re‑evaluated at the end of three months. Results: The perceived stress scale was significantly less in subjects practicing relaxation exercises, as compared to subjects only on medication. The waist/hip ratio, pulse rate, and systolic blood pressure were significantly lower, while there was no difference in the body mass index (BMI) and diastolic blood pressure. Results of the autonomic function tests showed a significant parasympathetic tilt in subjects practicing PMR. In patients with PCOS, who were on PMR, cholesterol, triglycerides, and low‑density cholesterol (LDL) were significantly lower and high‑density cholesterol HDL was significantly higher. Conclusions: PCOS patients are a high‑risk group for developing the metabolic syndrome and relaxation therapies may be recommended as an adjuvant therapy, to tilt the autonomic balance to parasympathetic dominance, to improve the cardiovascular profile.Keywords: Autonomic functions, cardiovascular system, polycystic ovarian syndrome, stres
