in this paper we find sufficient conditions on primitive inverse topological semigroup s under which: the inversion inv : (h(s)) (h(s)) is continuous; we show that every topologically periodic countable compact primitive inverse topological semigroups with closed h-classes is topologically isomorphic to an orthogonal sum p i2= bi (gi) of topological brandt extensions bi (gi) of countably compac...

when tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. they hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. one of this type of colloid agents, is tc-99-tin-colloid which is prepared by ...

results at high concentrations (40 and 100 μm), apoptosis was demonstrated and it was clearly more prominent in hepatocytes exposed to celecoxib loaded liposomes. conclusions our results showed that celecoxib loaded liposomes robustly induced apoptosis, an action that can potentially make it more relevant than the usual form for chemopreventive strategies and also may raise concerns about its t...

In the title compound, C(21)H(23)N(2)O(2)P, the P atom has a distorted tetra-hedral configuration. The O atom of the OC(6)H(4)-4-CH(3) group and the N atoms show sp(2) character. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into helical chains parallel to the b axis.

In the title mol-ecule, C(17)H(23)N(2)O(2)P, the P atom has a distorted tetra-hedral environment. The P-N bond to the tolyl-amido fragment is 1.642 (4) Å while that to the butyl-amido fragment is 1.629 (3) Å. The dihedral angle between the two benzene rings is 82.3 (2)°. In the crystal, adjacent mol-ecules are linked via weak N-H⋯(O)P and N-H⋯N hydrogen-bonding inter-actions into an extended ch...
