www.eg.org diglib.eg.org Abstract Studies aiming at increasing the sense of reality by using scents with the picture medium, such as movies, have lately attracted much attention. In the picture medium, multiple objects with different scents are seen at the same time. Therefore, it is thought that by controlling the presentation of scent in accordance with the various scented objects seen, the v...

Five CD1 molecules are expressed in humans and it is unclear whether they have specialized or redundant functions. We found that sulfatide is a promiscuous CD1-binding ligand and have isolated T cell clones that are specific for sulfatide and restricted by distinct CD1 molecules. These clones have been used to compare the capacity of different CD1 to present the same glycolipid, to induce effec...

There is a wide variability in the clinical presentation of Klinefelter's syndrome. We report the case of a 45-year-old man who was incidentally diagnosed a 47,XXY/46,XY karyotype in a bone marrow aspiration (case 1). He presented hypogonadic features with undetectable testosterone levels and a height in accordance with mid-parental height. He had a monozygous sibling (case 2) who did not show ...

differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. a number of studies have reported the effects of biochemical modifications of chromatin (dna and chromatin proteins) on the regulation of transcription. although, these studies are able to explain how transcription of a given gene is regulated (toward activation...

background degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. the principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. to briefly review the lines of research and potential candidates for cell based therapies among r...

elucidating the critical epigenetics events involved in differentiation and reprogramming of cells to primordial germ cells (pgcs) is among the interesting issues in stem cell research. here, i will talk about critical transcription factors and global hypomethylation in development of germ cells. evidence strongly suggests that the earliest pgcs emerging in the e7.25 mouse embryo epiblast have ...
