Serum galectin-3 concentrations in patients with ankylosing spondylitis.

Objective: The aim of our study was to assess potential correlations between serum galectin-3 concentrations and Ankylosing Spondylitis Disease Activity (ASDAS) index in patients with ankylosing spondylitis (AS).

Methods: A total of 112 patients with AS were included, and 130 healthy subjects were considered as controls. We collected the detailed medical history, and ASDAS index was used to assess the disease severity in patients with AS.

[Case-control study on modified Weaver-Dunn surgery combined with clavical hook-plate internal fixation for the treatment of Tossy type III acromioclavicular dislocation].

Objective: To compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

Methods: Forty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures.

11-Phenyl-[b,e]-dibenzazepine compounds: novel antitumor agents.

A series of 11-phenyl-[b,e]-dibenzazepine compounds were synthesized and shown to be inhibitors of tumor cell proliferation with IC(50) values ranging from submicromolar to micromolar concentrations. Flow cytometric analyses of several active compounds demonstrated inhibition of cell cycle progression at the G(0)-G(1) phase transition resulting in G(0)-G(1) arrest.

NK cell activation and tumor infiltration are involved in the antitumor mechanism of Virulizin.

Previous studies have demonstrated antitumor efficacy of Virulizin in several human tumor xenograft models and a critical role for macrophages in the antitumor mechanism of Virulizin. Although there is growing support for an immune stimulatory mechanism of action for Virulizin, the details remain to be elucidated. The aim of this study was to determine whether infiltration of natural killer (NK) cells into xenografted tumors is altered by Virulizin treatment, and whether such alterations contribute to the antitumor activity of Virulizin.

Triaryl methane derivatives as antiproliferative agents.

Clotrimazole (CLT) 1, a synthetic anti-fungal imidazole derivative, inhibits tumor cell proliferation and angiogenesis. In the current study, flow cytometric analysis demonstrated that the decrease in tumor cell growth by CLT 1 was associated with inhibition of cell cycle progression at the G(1)-S phase transition, resulting in G(0)-G(1) arrest. A series of CLT 1 analogues has been generated in order to develop CLT 1 derivatives that are devoid of the imidazole moiety which is responsible for the hepatoxicity associated with CLT 1 while retaining CLT 1 efficacy.

NC381, a novel anticancer agent, arrests the cell cycle in G0-G1 and inhibits lung tumor cell growth in vitro and in vivo.

Although clotrimazole (CLT), an antifungal drug, inhibits tumor cell proliferation and angiogenesis, its clinical application is hampered by significant hepatotoxicity due to the presence of an imidazole moiety. In our attempts to develop CLT analogs that are devoid of imidazole and are as efficacious as CLT, one pharmacophore designated NC381 was generated and shown to inhibit tumor cell growth via a mechanism similar to that of CLT. In vitro, treatment of NCI-H460 nonsmall cell lung cancer (NSCLC) cells with NC381 inhibited growth in a time-dependent manner.

Adenovirus-mediated ribonucleotide reductase R1 gene therapy of human colon adenocarcinoma.

Ribonucleotide reductase is the enzyme responsible for the reduction of ribonucleotides to their corresponding deoxyribonucleotides for DNA synthesis. Ribonucleotide reductase is a multisubunit complex containing two polypeptides, R1 and R2. In addition to catalytic and allosteric regulatory functions, the R1 subunit appears to act as a novel tumor suppressor.
