Background and aim: Tachyx is a rare autosomal recessive and neurological disorder caused by glycosfenolipid accumulation (GM2 ganglioside) in cell lysosomes. The accumulation of GM2 ganglioside is due to the mutation in the beta-hexose aminase gene (HEXA), which reduces the activity and deficiency of the HEXA enzyme. The aim of this study was to report 2 cases of T.Sax disease.   Case report:...

Domestic cats exhibit abundant variations in tail morphology and serve as an excellent model to study the development and evolution of vertebrate tails. Cats with shortened and kinked tails were first recorded in the Malayan archipelago by Charles Darwin in 1868 and remain quite common today in Southeast and East Asia. To elucidate the genetic basis of short tails in Asian cats, we built a pedi...

In this article, we introduce the multivariate slash and skew-slash t distributions which provide alternative choices in simulating and fitting skewed and heavy tailed data. We study their relationships with other distributions and give the densities, stochastic representations, moments, marginal distributions, distributions of linear combinations and characteristic functions of the random vect...

Determination of an accurate glenohumeral-joint rotation center (GH-JRC) from marker data is essential for kinematic and dynamic analysis of shoulder motions. Previous studies have focused on the evaluation of the different functional methods for the estimation of the GH-JRC for healthy subjects. The goal of this paper is to compare two widely used functional methods, namely the instantaneous h...

Until recently, Toxoplasma gondii was considered to be clonal with little genetic variability. In this paper we summarize recent genotyping data from chickens in Brazil, and pigs, lambs and white-tailed deer in the USA, to demonstrate the high genetic diversity and geographical distribution of T. gondii. A total of 149 T. gondii isolates from 13 geographical areas of Brazil and 182 T. gondii is...

this study compares and contrasts lexical cohesion in english and persian abstracts of iranian medical students’ theses to appreciate textualization processes in the two languages. for this purpose, one hundred english and persian abstracts were selected randomly and analyzed based on seddigh and yarmohamadi’s (1996) lexical cohesion framework, a version of halliday and hasan’s (1976) and halli...

We consider a system with two heterogeneous traffic classes, one having light-tailed characteristics, the other one exhibiting heavy-tailed properties. When both classes are backlogged, the two corresponding queues are each served at a certain nominal rate. However, when one queue empties, the service rate for the other class increases. This dynamic sharing of surplus service capacity is remini...
