Three Novel Mutations in Iranian Patients with Tay-Sachs Disease

Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in‌ an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing m...

Sachs-Wolfe effect in Spacetimes with Torsion

Cartan torsion contribution to Sachs-Wolfe effect in the inflationary phase of the Universe is discussed.From the COBE data of the microwave anisotropy is possible to compute the spin-density in the Universe as 10 mks units.The spin-density fluctuations at the hadron era is shown to coincide with the anisotropy temperature fluctuations.

Kantowski-Sachs String Cosmologies

We present new exact solutions of the low-energy-effective-action string equations with both dilaton φ and axion H fields non-zero. The background universe is of Kantowski-Sachs type. We consider the possibility of a pseudoscalar axion field h (H = eφ(dh)∗) that can be either time or space dependent. The case of time-dependent h reduces to that of a stiff perfect-fluid cosmology. For space-depe...

American Humor in Promoting the Talk over the Wall with a Focus on Robert Frost’s Poems

The Yankee is an American national phenomenon. He had leapt into national stature when slipped outside of his local character. A myth was woven around him and a cult of the Yankee developed by the permeation of the Yankee characteristics in many different characters who played tricks or told stories and entertained their audiences. The present article is an attempt to observe the Yankee myth, i...
