Most tetrameric channels have cytosolic domains to regulate their functions, including channel inactivation. Here we show that the cytosolic C-terminal region of NavSulP, a prokaryotic voltage-gated sodium channel cloned from Sulfitobacter pontiacus, accelerates channel inactivation. The crystal structure of the C-terminal region of NavSulP grafted into the C-terminus of a NaK channel revealed ...

This study explored the effects of cryogenic treatment on the microstructure, hardness, and wear-resistance of diamond-like carbon (DLC) by cryogenically treating NAK 80 mold steel coated with DLC. Raman spectroscopy analyzed the structure of the DLC film. Nanoindenter analyzed the hardness and Young’s modulus of the film, and their relationship determined the wear resistance. Wear test assesse...

Single-rate reliable multicast protocols are known to have scalability problems in the presence of a large number of receivers because the sender cannot distinguish independent packet losses at different receivers from multiple packet losses at the same receiver. In the presence of a large number of receivers, the sender may perceive a large aggregate packet loss even if no individual receiver ...

Az első világháborút követően az Egyesült Államok igyekezett befolyást kiépíteni olajlelőhelyek fölött, azonban ezek gyakran európai birodalmak befolyási zónáiban voltak. Törekvéseinek megvalósítására elsőkörben Perzsiában nyílt lehetősége a háborút követően. 1922-ben kiküldött, Arthur Millspaugh vezette pénzügyi szakértőgárda feladata volt, hogy egyrészt támogassa iráni modernizációt, másrészt...

Ultracold fermionic Feshbach molecules are promising candidates for exploring quantum matter with strong $p$-wave interactions; however, their lifetimes were measured to be short. Here we characterize the collisions of ultracold $^{23}\mathrm{Na}^{40}\mathrm{K}$ different scattering lengths and temperatures. By increasing binding energy molecules, two-body loss coefficient reduces by three orde...

Powdered leaves (500 mg/kg body weight) of medicinal plants M. indica and C. igneus known to possess therapeutic effect were supplemented to streptozotocin induced diabetic rats. Leaf powders of both the plants were able to reduce blood glucose levels in the animals by 38 and 21% respectively after 15 days of supplementation. The preliminary results suggest that both the plants possess potent h...
