Abstract 47 Sc can be produced from different three neutron induced nuclear reactions as Ti(n,p) Sc, 50 V(n,?) and 46 Ca(n,?) Ca, Ca(? ? ) using the Egyptian Second Research Reactor. The measured cross-sections (?) are 62.12 ± 1.93, 4.51 1.27 69.36 2.01 mb natural targets of TiO 2 , V O 3 CaO respectively. carrier-free Ti(n,p), was purified a composite Alginate–Carboxymethyl cellulose/di-2-ethy...

The lipooligosaccharide (LOS) of Haemophilus influenzae contains sialylated glycoforms, and a sialyltransferase, Lic3A, has been previously identified. We report evidence for two additional sialyltransferases, SiaA, and LsgB, that affect N-acetyllactosamine containing glycoforms. Mutations in genes we have designated siaA and lsgB affected only the sialylated glycoforms containing N-acetylhexos...

cADPR (cyclic ADP-ribose) is a universal Ca(2+) mobilizing second messenger. In T-cells cADPR is involved in sustained Ca(2+) release and also in Ca(2+) entry. Potential mechanisms for the latter include either capacitative Ca(2+) entry, secondary to store depletion by cADPR, or direct activation of the non-selective cation channel TRPM2 (transient receptor potential cation channel, subfamily m...
