Di-n-butyl 5-amino-isophthalate.

The title compound, C(16)H(23)NO(4), is essentially planar except for the last two C atoms in each n-butyl group (r.m.s.

Bis(6-meth-oxy-2-{[tris-(hydroxy-meth-yl)methyl-κO]imino-meth-yl}phenolato-κN,O)nickel(II) dihydrate.

In the title compound, [Ni(C(12)H(16)NO(5))(2)]·2H(2)O, the Ni(II) atom is coordinated by four O atoms and two N atoms from the two 6-meth-oxy-2-{[tris-(hydroxy-meth-yl)meth-yl]imino-meth-yl}phenolate ligands in a distorted octa-hedral coordination geometry. O-H⋯O hydrogen bonds link the complexes and uncoordinated water mol-ecules into two-dimensional networks parallel to (001).

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], was obtained by solvothermal synthesis. The Cu(II) atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxyl-ate ligands, leading to a distorted octahedral environment. Each carboxyl-ate group makes one short Cu-O bond [1.

cyclo-Tris[μ-5-(2-pyrid-yl)pyrazol-1-ido-κN,N:N]tris-ilver(I).

In the title compound, [Ag(3)(C(8)H(6)N(3))(3)], the asymmetric unit contains three silver cations and three depronated 5-(2-pyrid-yl)pyrazol-1-ide ligands. Each silver cation is chelated by one 5-(2-pyrid-yl)pyrazol-1-ide ligand, which also acts as a bridging ligand towards the next silver ion via the second pyrazole N atom. In summary, three silver cations and three deprotonated 3-(2-pyrid-yl)-1H-pyrazole ligands produce a macrocyclic trimeric coordination oligomer that exhibits an almost planar conformation (mean deviation 0.

Expression of P16(INK4a) in testis of rhesus monkey during heat stress and testosterone undecanoate induced azoospermia or oligozoospermia.

Previous studies on azoospermia or oligozoospermia induced by heat stress or high doses of testosterone mainly focused on germ cell apoptosis; no data regarding their possible effect on spermatogonia mitosis are available. We have established unilateral cryptorchid and testosterone undecanoate (TU)-treated monkey models and examined expression of P16(INK4a) in the testis to look at its possible role in azoospermia or oligozoospermia induced by the heat stress or the TU treatment. The results showed that both heat stress and TU were capable of inducing expression of P16(INK4a) mainly in spermatogonia and other types of germ cells as well as Sertoli cells at the later stage of germ cell apoptosis, namely on Day 10 after operation or on Day 60 after TU injection.
