From the discrete radon transform (DRT), R(t, m) of a p x p image I(x, y), intensity at (t, m) results from the sum of intensities, I of elements, (x, y) along a projection of x = my + t (mod p), the resultant transform of the image presented has an averaging effect. If information is required for a subset of the image, it cannot be extracted from transform of the complete image. It is therefor...

BACKGROUND/AIMS Amiodarone, a thyroid hormone-like molecule, can induce dyslipidemia and thyroid dysfunction. However, the effects of dronedarone on lipid metabolism and of both dronedarone and amiodarone on thyroid function and lipid metabolism remain unknown. METHODS Fifty male Sprague-Dawley rats were randomly divided into 5 groups (10 in each group): normal control (NC), amiodarone-treate...

Purpose: To assess the association between the features of optical coherence tomography (OCT) and fluorescein angiography (FA) in clinically significant diabetic macular edema. Materials and Methods: It was an observational, cross-sectional study conducted at Upgraded Department of Ophthalmology, S.M.S Hospital and Medical College, Jaipur. It involved 181 eyes (100 patients) with clinically sig...

Variables on which constraints are imposed incrementally can be said to carry \existential" force in the following sense. Under a translation, commonly used in analyzing natural language discourse, of rst-order formulas into programs from quantiied dynamic logic, such a variable is introduced (at the level of formulas) by an existential quantiier. The present paper extends that translation to s...

The ventral intermediate nucleus (VIM) of the thalamus is an established surgical target for stereotactic ablation and deep brain stimulation (DBS) in the treatment of tremor in Parkinson's disease (PD) and essential tremor (ET). It is centrally placed on a cerebello-thalamo-cortical network connecting the primary motor cortex, to the dentate nucleus of the contralateral cerebellum through the ...

BACKGROUND This study was performed to determine the incidence of central venous device-related blood stream infection and thrombosis in patients treated with moderate dose continuous-infusion interleukin-2 (IL-2). METHODS The records of 160 consecutive patients treated at the University of Wisconsin Hospital and Clinics, between June 1990 and June 1997, with moderate dose continuous-infusion...

Motivated by the RNA world hypothesis, Michael Yarus and colleagues have proposed a model for the origin of the ‘universal’ genetic code, in which RNA aptamers directly template amino acids for protein assembly. Yarus et al. claim that this “direct RNA templating” (DRT) model provides a stereochemical basis for the origin of the code, as shown by the higher-thanexpected frequency of cognate cod...

PURPOSE Visual disturbances that make it difficult to read text are often termed "visual stress". Coloured filters in spectacles may help some children overcome reading problems that are often caused by visual stress. It has been suggested that for optimal effect each child requires an individually prescribed colour for each eye, as determined in systems such as the "Harris Foundation" coloured...

BACKGROUND Impulsive and compulsive behaviors (ICBs) are a heterogeneous group of conditions that may be caused by long-term dopaminergic replacement therapy (DRT) of Parkinson's disease (PD). The spectrum of ICBs includes dopamine dysregulation syndrome (DDS), punding, and impulse control disorders (ICDs). CONTENTS We made a detailed review regarding the epidemiology, pathology, clinical cha...
