in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
In 13 patients, the GM2 gangliosidoses, Sandhoff disease and Tay-Sachs disease, were found to be constantly associated with homogeneously and symmetrically increased CT attenuation within the thalami. In the only patient examined with MR imaging, a T2-weighted sequence showed hypointense thalami. It is suggested that this finding is caused by an accumulation of calcium, associated with the intr...
Abstract Sandhoff disease (SD) is an ultra-rare lysosomal storage disorder (LSD), which affects ~ 1/1000, 000 live birth. SD caused by genetic deficiency of beta (β) Hexosaminidase and resulting excess central nervous system (CNS) synthesis GM2 ganglioside (GM2) its impact on neuron death. The exact mechanisms underlying such GM2-driven death are unknown in SD. Glucosylceramide (GC) induced com...
X-ray absorption near-edge spectroscopy (XANES) at the Mn K-edge was used to investigate the environment of Mn in situ within the growth increments of the long-lived freshwater bivalve species Diplodon chilensis patagonicus. Single XANES spectra and Mn Kalpha fluorescence distributions were acquired at submillimetre resolution (up to 100 microm x 50 microm), at Mn concentrations below the weigh...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
novel mutations in sandhoff disease: a molecular analysis among iranian cohort of infantile patients
background: sandhoff disease is an autosomal recessive disorder caused by β-hexosaminidase deficiency and accumulation of gm2 ganglioside resulting in progressive motor neuron manifestations and death from respiratory failure and infections in infantiles. pathogenic mutations in hexb gene were observed which leads to enzyme activity reduction and interruption of normal metabolic cycle of gm2 ga...
Multiple mechanisms have been proposed to account for immune escape by tumors. Although gangliosides have long been known to suppress T-cell immunity, few studies have examined the effect of human tumor-derived gangliosides on immune responses. Here, we show that gangliosides isolated from renal cell carcinoma (RCC) cell lines and clear cell tumor tissue can induce apoptosis in peripheral blood...
