When motile swarmer cells of Caulobacter crescentus differentiate into sessile stalked cells, the flagellum is ejected. To elucidate the molecular mechanism of the flagellar ejection, flagellar hook-basal body (HBB) complexes from C. crescentus were purified and characterized. The purified HBBs were less stable against acidic pH or protease treatment than HBBs of Salmonella typhimurium, support...

The present investigation has been undertaken to study the Hemoglobin and Transferrin polymorphisms in indigenous goat breed Salem Black of Tamil Nadu. A total of fifty blood samples from the adult male and female local breed of Salem Black goats were collected, among which 40 samples from Mecheri Sheep Research Station, Pottaneri, Salem and 10 samples from Institutional Livestock Farming Compl...

We observed (22) Kalliope and its companion Linus with the integral-field spectrograph OSIRIS, which is coupled to the adaptive optics system at the W.M. Keck 2 telescope on March 25 2008. We present, for the first time, component-resolved spectra acquired simultaneously in each of the Zbb (1-1.18μm), Jbb (1.18-1.42μm), Hbb (1.47-1.80μm), and Kbb (1.97-2.38μm) bands. The spectra of the two bodi...

We present an overview of searches for MSSM Higgs at the Tevatron, concentrating on searches probing the high tanβ region. We discuss the search for A/H → ττ which is soon to be completed in the Run I data and review the new tau triggers implemented by CDF and D0 in Run II, which will greatly impact this analysis. We also present the results of a Run I search for A/Hbb→ bbbb performed by CDF an...

Nascent transcription occurs at nuclear foci of concentrated, hyperphosphorylated RNA polymerase II (RNAPII). We investigate RNAPII localization, distal gene co-association, and Hbb locus conformation during inhibition of transcription. Our results show distal active genes remain associated with RNAPII foci and each other in the absence of elongation. When initiation is inhibited, active genes ...

So far, more than 800 mutations involving the beta-globin gene have been characterized worldwide. Most of these variants are also carried by patients with Turkish origin, since Turkey is one of the hotspot regions for mutations of the globin genes.1 In the present study, we report a case with an unusual high-performance liquid chromatography (HPLC) pattern who turned out to be a carrier of the ...

Self-Synchronizing Stream Ciphers (SSSC) are a particular class of symmetric encryption algorithms, such that the resynchronization is automatic, in case of error during the transmission of the ciphertext. In this paper, we extend the scope of chosen-ciphertext attacks against SSSC. Previous work in this area include the cryptanalysis of dedicated constructions, like KNOT, HBB or SSS. We go fur...

We present a large and homogeneous sample of optical and UV observations of PNe and derive their abundances and the implications for the Intermediate Mass Stars (IMS) and Galactic chemical evolution. We observe the “hot bottom burning” (HBB) reaction, oxygen depletion (ON cycle) and/or production (likewise carbon) during the third dredge-up. All these effects are more efficient at lower metalli...
