The interaction of sodium phytate hydrate CHOP·xNa·yHO (phytNa) with Cu(OAc)·HO and 1,10-phenanthroline (phen) led to the anionic tetranuclear complex [Cu(HO)(phen)(phyt)]·2Na·2NH·32HO (), the structure of the latter was determined by X-ray diffraction analysis. The phytate is completely deprotonated; six phosphate fragments (with atoms P1-P6) are characterized by different spatial arrangements relative to the cyclohexane ring (1a5e conformation), which determines two different types of coordination to the complexing agents-P1 and P3, P4, and P6 have monodentate, while P2 and P5 are bidentately bound to Cu cations. The molecular structure of the anion complex is stabilized by a set of strong intramolecular hydrogen bonds involving coordinated water molecules.

- The study aimed to assess how post-processing of CT results can help in non-invasively diagnosing pancreatic fibrosis (PF) in patients with chronic pancreatitis and pancreatic cancer.
- It involved 165 patients, where contrast ratios of pancreatic tissues were measured, and the degree of PF was evaluated using established scales.
- Results showed that higher contrast ratios correlated with more severe PF and that signs of inflammation in pancreatic tissues also indicated increased contrast ratios, suggesting a link between CT results and morphological signs of PF.
Article Synopsis
- Pancreatic fibrosis (PF) is key in chronic pancreatitis and this study examined its relationship with various factors in pancreatic specimens from 74 patients.
- Significant differences were found in imaging parameters (like unenhanced pancreas density and contrast enhancement ratio) based on fibrosis grades and inflammation indicators in the tissue.
- Blood levels of fibronectin and hyaluronic acid showed correlations with different aspects of fibrosis, suggesting that these and imaging parameters could aid in non-invasive diagnosis of PF.
The purpose of the research was to obtain an arc welded joint of a preliminary quenched high-carbon wear resistant steel without losing the structure that is previously obtained by heat treatment. 120Mn3Si2 steel was chosen for experiments due to its good resistance to mechanical wear. The fast cooling of welding joints in water was carried out right after welding.
