A seven-coordinate Mn(II) complex with a pyridine-based 15-membered macrocyclic ligand containing one acetate pendant arm: structure, stability and relaxation properties.

A new 15-membered pyridine-based macrocyclic ligand containing one acetate pendant arm (-carboxymethyl-3,12,18-triaza-6,9-dioxabicyclo[12.3.1]octadeca-1(18),14,16-triene, L1) was synthesized and its Mn(II) complex MnL1 was investigated in the context of MRI contrast agent development.

Prognostic significance of TIMP-1 in non-small cell lung cancer.

Unlabelled: Tissue inhibitor of metalloproteinases 1 (TIMP1) regulates not only extracellular matrix catabolism but the major effect in tumor tissue is promotion of cell growth and anti-apoptotic activity. The aim of our study was to evaluate plasma TIMP1 levels and tissue TIMP1 mRNA expression as prognostic markers in NSCLC patients.

Patients And Methods: We studied a group of 108 patients with NSCLC who had undergone lung surgery.

Vitamin D in colorectal, breast, prostate and lung cancer: a pilot study.

Background: Many studies have demonstrated the relationship between vitamin D and cancer of many different sites, including of the breast, colorectum, prostate and lung. Most epidemiological studies have assessed the effects of dietary intake only, although endogenous production after sun exposure is the main source of vitamin D. The aim of our pilot study was to study serum levels of vitamin D in general population and in patients with different type of cancer.

The role of MonoTotal in the primary diagnosis, prognosis and follow-up of patients with non-small cell lung cancer (NSCLC).

Background: A new cytokeratin tumor marker, MonoTotal was studied in lung cancer, the most common cause of cancer mortality worldwide. In non-small cell lung cancer (NSCLC) patients MonoTotal serum levels and their relationship to the tumor stage, histological subtype, early relapse and cancer-related death were evaluated.

Patients And Methods: MonoTotal serum levels were studied, using immunoradiometric assay in a group of 93 patients with newly diagnosed NSCLC undergoing radical surgery, and were compared to those with benign lung diseases.

Test of ovarian cancer multiplex xMAP technology panel.

Background: An ovarian cancer marker panel including leptin, prolactin, osteopontin, insulin-like growth factor II (IGFII), macrophage migration inhibitory factor and CA125 was tested for multiplex marker measurement. Multiplex was compared to single assayed tumour markers: CA125, TPS, thymidine kinase, monototal and HE4.

Patients And Methods: The serum marker levels in ovarian cancer patients were compared to controls with benign ovarian disease.

Gliclazide: pharmacokinetic-pharmacodynamic relationships in rats.

The relationship between the pharmacokinetics of gliclazide and its antidiabetic efficacy were evaluated on the basis of experimental determination of changes with time in the plasma levels of this antidiabetic agent and those of glucose. The experiment included rats with both initial normal glycaemia and alloxan-induced hyperglycaemia (glycaemia increased by a minimum of 30%). Pharmacokinetic and pharmacodynamic parameters were examined in the interval of 30 to 180 min after p.

Long-term studies (1871-2000) on acidification and recovery of lakes in the Bohemian Forest (central Europe).

This paper evaluates long-term changes in the atmospheric depositions of S and N compounds, lake water quality, and biodiversity at eight glacial lakes in the Bohemian Forest over the past 130 years. This time interval covers (i) the 'background' pre-acidification status of the lakes, (ii) a period of changes in the communities that can be partly explained by introduction of fish, (iii) a period of strong lake acidification with its adverse impacts on the communities, (iv) the lake reversal from acidity, which includes the recent status of the lakes. The lake water chemistry has followed-with a characteristic hysteresis-both the sharp increase and decline in the deposition trends of strong anions.
