A DNA-Inspired Synthetic Ion Channel Based on G-C Base Pairing
No full textA dinucleoside containing guanosine and cytidine at the end groups has been prepared using a modular one-pot azide-alkyne cycloaddition. Single channel analysis showed that this dinucleoside predominantly forms large channels with 2.9 nS conductance for the transport of potassium ions across a phospholipid bilayer. Transmission electron microscopy, atomic force microscopy, and circular dichroism spectroscopy studies reveal that this dinucleoside can spontaneously associate through Watson-Crick canonical H-bonding and pi-pi stacking to form stable supramolecular nanostructures. Most importantly, the ion channel activity of this G-C dinucleoside can be inhibited using the nucleobase cytosine
A brief description of the writings, author and period of composition etc. in the family memoir book/ পারিবারিক স্মৃতিলিপি পুস্তকে লেখা, লেখক ও রচনাকাল প্রভৃতির সংক্ষিপ্ত বিবরণ
No full textThe Proverbial Professor Pasupati Sasmal once researched the family memoirs of Jorasanko Thakurbari. Mainly following his research, a brief list of various writings including serial number, title of part of the first line, author, period of composition, page of manuscript etc. is presented here. This is the first part of the given description. The second part of it is as follows: After writing No.105, the list and description (in the second part) of all the remaining writings which are not given serial numbers are also given. Interested Rabindra-inquisitors can know almost all the information at a glance from this list

No full textAbstractIf the origin of neutrino masses is due to physics at the TeV scale, it would be of tremendous interest since it can be probed using ongoing collider as well as low energy rare process searches. So, a key question is: could the new physics behind neutrino masses be near the TeV scale? In this brief overview, I present arguments in favor of this possibility by presenting the example of TeV scale left–right symmetric models (LRSM) for neutrino mass based on type I seesaw paradigm. A particular issue with understanding the small neutrino masses in TeV scale LRSM is to understand the suppression of type II seesaw contribution to neutrino masses, which a priori could be much larger than desired. I discuss how using either D-parity breaking or by using supersymmetry, one can suppress these contributions to the desired level in a natural way. Experimental probes of this hypothesis are briefly touched upon. Constraints of supersymmetry and that of successful leptogenesis on the left–right scale are also emphasized. The former provides an upper limit and the latter, a lower limit on mWR
