Spectropolarimetry and nebular geometry of the symbiotic star HBV 475 ?
Wepresent and discuss spectropolarimetry of theRaman scattered emission features atλ6825 andλ7082 of the symbiotic nova HBV 475. Meaningful interpretation in relation to the orbital phase requires an improved ephemeris and we first review available photometry and deduce a newperiod of 956.5 d and minimum epoch at JD 2 444 890. The flux of the λ6825 line varies with photometric phase by about a ...
متن کاملHMGA1 pseudogenes as candidate proto-oncogenic competitive endogenous RNAs
The High Mobility Group A (HMGA) are nuclear proteins that participate in the organization of nucleoprotein complexes involved in chromatin structure, replication and gene transcription. HMGA overexpression is a feature of human cancer and plays a causal role in cell transformation. Since non-coding RNAs and pseudogenes are now recognized to be important in physiology and disease, we investigat...
متن کاملA proto brown dwarf candidate in Taurus
Aims. We search for brown dwarfs at the Class 0/I evolutionary stage, or proto brown dwarfs. Methods. We present a multi wavelength study, ranging from optical at 0.8 μm to radio wavelengths at 6 cm, of a cool, very faint, and red multiple object, SSTB213 J041757, detected by Spitzer toward the Barnard 213 dark cloud, in Taurus. Results. The SED of SSTB213 J041757 displays a clear excess at lon...
متن کامل475 The Candidate Peptides in IgE for Allergy Vaccine Design
IgE, and atopy. Results: We measured the total serum IgE of 155 children. The number of obese and normal weight children with family history of atopic disease who had high level of total serum IgE were 30 and 25 respectively, whereas these children who had normal level of total serum IgE were 6 and 15 respectively [OR 1⁄4 1.9 (95% CI 0.9-3.9)]. On the other hand, obese and normal weight childre...
متن کاملGenus Boswellia as a new candidate for neurodegenerative disorders
Neurodegenerative diseases, characterized by progressive loss of neurons, share common mechanisms such as apoptotic cell death, mitochondrial dysfunction, inflammation, and oxidative stress. Genus Boswellia is a genus in the Burseraceae family. It comprises several species traditionally used for treatment of chronic inflammatory diseases, cerebral edema, chronic pain syndrome, gastrointestinal d...
