Pretreatment level of serum sialic acid predicts both qualitative and quantitative bone metastases of prostate cancer.

Background: Recently, serum sialic acid (SA) has emerged as a distinct prognostic marker for prostate cancer (PCa) and bone metastases, warranting differential treatment and prognosis for low-volume (LVD) and high-volume disease (HVD). In clinical settings, evaluating bone metastases can prove advantageous.

Objectives: We aimed to establish the correlation between SA and both bone metastasis and HVD in newly diagnosed PCa patients.

Synthesis, structure, topology and magnetic properties of cobalt(II) coordination polymers with 2-nitrobiphenyl-4,4'-dicarboxylic acid and bis(pyridyl) ligands.

Four coordination polymers, [Co2(Hnbpdc)2(nbpdc)(bipy)2]n (1), [Co3(nbpdc)3(bipy)3(H2O)2]n·2nH2O (2), [Co4(nbpdc)4(bipy)(H2O)4]n (3), and [Co2(nbpdc)2(bpee)(3/2)]n·0.25nH2O (4) [H2nbpdc = 2-nitrobiphenyl-4,4′-dicarboxylic acid, bipy = 4,4′-bipyridine and bpee = 1,2-di(4-pyridyl)ethane] have been synthesized by hydrothermal methods and studied by means of X-ray crystallography, topological analyses and magnetic analyses. Compounds 1–3 were synthesized from the same reactants under controlled conditions (pH and ligand ratio).

Solvent-modulated metamagnetism in a nickel(ii) coordination polymer with mixed azide and carboxylate bridges.

A novel 2D coordination polymer consisting of ferromagnetic Ni(ii) chains with alternating double EO-azide bridges and (EO-azide)bis(carboxylate) triple bridges exhibits solvent-modulated metamagnetism, and the reversible dehydration/hydration processes are accompanied by significant changes in critical temperature, critical field and hysteresis.

Bis[3-(2-carboxy-ethen-yl)pyridinium-1-acetato]dichloridozinc(II).

In the title complex, [ZnCl(2)(C(10)H(9)NO(4))(2)], the Zn(II) ion lies on a twofold rotation axis and is four-coordinated by two carboxyl-ate O atoms from two 3-(2-carboxy-ethen-yl)pyridinium-1-acetate ligands in a monodentate mode and two Cl atoms in a distorted tetra-hedral geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a double-chain structure extending parallel to [101].
