Obesity is recognized as a major, worldwide, health problem. Excess weight greatly increases the risk for cardiovascular diseases, diabetes and renal diseases. The present study was conducted in Department of Physiology, Index Medical College, Indore. 50 obese (25 male 25 female) non-obese were included. Sympathetic tests performed on both groups. All data are expressed mean± standard deviation...
Most of the empirical applications of the stochatic volatility (SV) model are based on the assumption that the conditional distribution of returns given the latent volatility process is normal. In this paper the SV model based on a conditional normal distribution is compared with SV speciications using conditional heavy-tailed distributions, especially Student's t-distribution and the generaliz...
We propose a robust Poisson geometric process model with heavy-tailed distributions to cope with the problem of outliers as it may lead to an overestimation of mean and variance resulting in inaccurate interpretations of the situations. Two heavy-tailed distributions namely Student’s t and exponential power distributions with different tailednesses and kurtoses are used and they are represented...
The current study was undertaken to determine if white-tailed deer in south Texas harbor Babesia bovis, a causative agent of bovine babesiosis. Blood samples from free-ranging white-tailed deer (Odocoileus virginianus) on two ranches in LaSalle and Webb Counties were screened for B. bovis and other hemoparasites by the polymerase chain reaction (PCR) to detect the piroplasm 18S rDNA. Serology w...
This study was aimed at assessing the extent of correlation between anaemia and malaria amongst paediatric patients attending Paediatric clinics of Murtala Muhammed Specialist Hospital (MMSH), and Hasiya Bayero Paediatric Hospital (HBPH). Two age groups (0-5 and 6-12 years old) were studied (both male and female). Three hundred samples of blood were examined for Malarial Parasites (MP). Two hun...
We consider the analysis of time series data, with particular emphasis on series which have a heavy-tailed structure | that is, whose marginal distributions have a right tail which is regularly varying at innnity with index ?. A natural model to attempt to t to time series data is an autoregression of order p, where p itself is often determined from the data. Recently several methods of paramet...
BACKGROUND Therapeutic drug monitoring for mycophenolic acid (MPA) is increasingly being advocated. The present therapeutic range relates to the 12-hour area under the serum concentration time profile (AUC).However, this is a cumbersome, tedious, cost restricting procedure. Is it possible to reduce this sampling period? AIM To compare the AUC from a reduced sampling strategy with the full 12-...
The generative learning strategy assisted by flash animation had not been applied to overcome learners’ misconceptions. This research aims find out the effectiveness of remediate misconceptions toward Newton’s law about gravity and determine way decrease after intervention. quasi-experimental method with pretest-posttest control group design. was conducted at Public Senior High School 5 Yogyaka...
BACKGROUND AND PURPOSE Pretreatment with intraventricular brain-derived neurotrophic factor (BDNF) reduces ischemic damage after focal cerebral ischemia. In this experiment we studied the effect of intravenous BDNF delivered after focal cerebral ischemia on neurological outcome, infarct size, and expression of proapoptotic and antiapoptotic proteins Bax and Bcl-2, respectively. METHODS With t...
