L-carnitine is essential for energy production and fatty acid metabolism. This study was designed to evaluate effects of L-carnitine on liver enzymes in rats fed cholesterol rich diet. Thirty two healthy male Wistar Albino rats were divided to four groups as Control (K), Cholesterol (C), L-carnitine (L) and L-carnitine+cholesterol (LC). All rats were kept in individual cages during the experime...

OBJECTIVE To measure aspartate aminotransferase (AST) activity in the pulp of teeth treated with fixed appliances for 6 months, and compare it with AST activity measured in untreated teeth. METHODS The study sample consisted of 16 healthy subjects (mean age 25.7 ± 4.3 years) who required the extraction of maxillary premolars for orthodontic reasons. Of these, 6 individuals had a total of 11 s...

BACKGROUND The current standard for the evaluation of children with blunt abdominal trauma (BAT) consists of physical examination, screening lab values, and computed tomography (CT) scan. We sought to determine if the focused assessment with sonography for trauma (FAST) combined with elevated liver transaminases (AST/ALT) could be used as a screening tool for intra-abdominal injury (IAI) in ped...

The theory of the proximal point algorithm for maximal monotone operators is applied to three algorithms for solving convex programs, one of which has not previously been formulated. Rate-of-convergence results for the "method of multipliers," of the strong sort already known, are derived in a generalized form relevant also to problems beyond the compass of the standard second-order conditions ...

BACKGROUND We evaluated the reliability and accuracy of the combined use of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) bacterial identification and Vitek 2 antimicrobial susceptibility testing (AST) for bacteria from positive blood culture bottles. METHODS Direct identification and AST were performed in parallel to the standard methods in monom...

The well-established method of phase reduction neglects information about a limit-cycle oscillator's approach towards its periodic orbit. Consequently, phase reduction suffers in practicality unless the magnitude of the Floquet multipliers of the underlying limit cycle are small in magnitude. By defining isostable coordinates of a periodic orbit, we present an augmentation to classical phase re...

We show that standard expenditure multipliers capture economy-wide effects of new government projects only when financing constraints are not binding. In actual policy making, however, new projects usually need financing. Under liquidity constraints, new projects are subject to two opposite effects: an income effect and a set of spending substitution effects. The former is the traditional, unre...

In standard solutions, the new-Keynesian model produces a deep recession with deflation in a liquidity trap. Useless government spending, technical regress, and capital destruction have large positive multipliers. The recession, deflation and policy paradoxes are larger when prices are less sticky. I show that these features are all artifacts of equilibrium selection. For the same interest-rate...

In the paper: an efficient VLSI architecture for a 8x 8 twodimensional discrete cosine transform and inverse discrete cosine transform (2-D DCTIIDCT) with a new 1-D DCTIIDCT algorithm is presented. The proposed new algorithm makes all coeficients are positive to simplify the design of multipliers and the coefficients have less round-off error than Lee's algorithm [ I ] . For computing 2-D DCTII...
